Abstract

Embodiments of the present disclosure provide a safety protection device for Raman spectroscopy detection and a Raman spectroscopy detection system including the safety protection device. The safety protection device includes: a detection cavity including a cavity body, the cavity body having an opening end through which a sample to be detected is allowed to be placed into the detection cavity; and a cover configured to cover and engage the opening end so as to form, together with the detection cavity, an explosion proof container defining a space for receiving the sample to be detected, the detection cavity further includes a detection opening formed in the cavity body such that a Raman detection probe is allowed to be inserted into the space through the detection opening so as to detect the sample.

First claim

What is claimed is:

1. A safety protection device for Raman spectroscopy detection, comprising:
a detection cavity comprising a cavity body, the cavity body having an opening end through which a sample to be detected is allowed to be placed into the detection cavity;
a cover configured to cover and engage the opening end so as to form, together with the detection cavity, an explosion proof container defining a space for receiving the sample to be detected,
a sample holder which is provided within the detection cavity and on which the sample to be detected is placed, wherein the sample holder comprises:
a base mounted within the detection cavity and having a detection region on which the sample to be detected is to be placed; and
a shielding plate connected with the base, the shielding plate being configured such that the detection opening and the detection region are located on opposite sides of the shielding plate and having an open pore aligned with the detection opening so that a Raman detection probe is allowed to pass through the detection opening and the open pore that are aligned with each other so as to be located near the detection region, and
wherein the detection cavity further comprises a detection opening formed in the cavity body such that the Raman detection probe is allowed to be inserted into the space through the detection opening so as to detect the sample.

2. The safety protection device according to claim 1 , further comprising a probe limiting block located within the detection cavity and configured to guide and hold the Raman detection probe that passes through the detection opening to be located near the detection region.

3. The safety protection device according to claim 2 , wherein the probe limiting block comprises a limiting hole configured to be aligned with the detection opening and the open pore so as to receive the Raman detection probe.

4. The safety protection device according to claim 2 , wherein the probe limiting block is positioned within the detection cavity between a side wall of the detection cavity in which the detection opening is formed and the shielding plate.

5. The safety protection device according to claim 1 , wherein the detection cavity and/or the cover further comprises a pressure relief opening in communication with the space.

6. The safety protection device according to claim 1 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

7. The safety protection device according to claim 2 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

8. The safety protection device according to claim 1 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

9. The safety protection device according to claim 2 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

10. The safety protection device according to claim 3 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

11. The safety protection device according to claim 4 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

12. The safety protection device according to claim 5 , wherein
the detection cavity further comprises a notched engagement ring located at the opening end and formed with a first engagement structure, and
the cover is formed with a second engagement structure configured to be engaged and locked with the first engagement structure.

13. The safety protection device according to claim 6 , wherein the first engagement structure comprises a plurality of notch engagement structures circumferentially spaced apart from each other, and the second engagement structure comprises a plurality of engagement legs each configured to engage a corresponding one of the notch engagement structures in a snap fit connection such that the cover is detachably engaged and locked to detection cavity.

14. The safety protection device according to claim 7 , wherein the first engagement structure comprises a plurality of notch engagement structures circumferentially spaced apart from each other, and the second engagement structure comprises a plurality of engagement legs each configured to engage a corresponding one of the notch engagement structures in a snap fit connection such that the cover is detachably engaged and locked to detection cavity.

15. The safety protection device according to claim 8 , wherein the first engagement structure comprises a plurality of notch engagement structures circumferentially spaced apart from each other, and the second engagement structure comprises a plurality of engagement legs each configured to engage a corresponding one of the notch engagement structures in a snap fit connection such that the cover is detachably engaged and locked to detection cavity.

16. The safety protection device according to claim 9 , wherein the first engagement structure comprises a plurality of notch engagement structures circumferentially spaced apart from each other, and the second engagement structure comprises a plurality of engagement legs each configured to engage a corresponding one of the notch engagement structures in a snap fit connection such that the cover is detachably engaged and locked to detection cavity.

17. The safety protection device according to claim 10 , wherein the first engagement structure comprises a plurality of notch engagement structures circumferentially spaced apart from each other, and the second engagement structure comprises a plurality of engagement legs each configured to engage a corresponding one of the notch engagement structures in a snap fit connection such that the cover is detachably engaged and locked to detection cavity.

18. A Raman spectroscopy detection system, comprising:
