Abstract

An insulation assembly comprises an insulation pipe, an insulation umbrella group, and an insulation base. The insulation pipe has a first end and a second end opposite to the first end. The insulation umbrella group is formed on an outer wall of the insulation pipe. The insulation base is made of an insulating material and connected to the first end of the insulation pipe.

First claim

What is claimed is:

1. An insulation assembly, comprising:
an insulation pipe having a first end and a second end opposite to the first end;
an insulation umbrella group formed on an outer wall of the insulation pipe; and
an insulation base made of an insulating material and connected to the first end of the insulation pipe, the insulation base has an insulation flange and an insulation connection tube, a first end of the insulation connection tube is connected to the first end of the insulation pipe and a second end of the insulation connection tube opposite to the first end is connected to the insulation flange.

2. The insulation assembly of claim 1 , wherein the insulation base has a plurality of reinforcing ribs each connected to outer walls of the insulation flange and the insulation connection tube.

3. The insulation assembly of claim 2 , wherein the reinforcing ribs are uniformly distributed and spaced around a circumference of the insulation connection tube.

4. The insulation assembly of claim 3 , wherein a plurality of installation holes are formed in the insulation flange, each of the installation holes disposed at a middle position between adjacent reinforcing ribs of the plurality of reinforcing ribs.

5. The insulation assembly of claim 1 , wherein the insulation base is integrally formed by molding.

6. The insulation assembly of claim 1 , wherein the insulation connection tube has a constant diameter.

7. The insulation assembly of claim 6 , wherein an inner diameter of the insulation pipe is larger than an outer diameter of the insulation connection tube and the first end of the insulation pipe is sleeved and connected to an outer wall of the first end of the insulation connection tube.

8. The insulation assembly of claim 6 , wherein an outer diameter of the insulation pipe is less than an inner diameter of the insulation connection tube and the first end of the insulation connection tube is sleeved and connected to the outer wall of the first end of the insulation pipe.

9. The insulation assembly of claim 1 , wherein the insulation connection tube has a plurality of different diameters.

10. The insulation assembly of claim 9 , wherein the insulation connection tube has:
(a) a first tube portion disposed at the first end of the insulation connection tube distal from the insulation flange, the first tube portion having a first constant outer diameter,
(b) a second tube portion disposed at the second end of the insulation connection tube proximal the insulation flange, the second tube portion having a second constant outer diameter greater than the first constant outer diameter, and
(c) a third tube portion connected between the first tube portion and the second tube portion, the third tube portion having a third outer diameter gradually changing from the first constant outer diameter to the second constant outer diameter.

11. The insulation assembly of claim 10 , wherein an inner diameter of the insulation pipe is larger than an outer diameter of the first tube portion of the insulation connection tube and the first end of the insulation pipe is sleeved and connected to an outer wall of the first tube portion of the insulation connection tube.

12. The insulation assembly of claim 10 , wherein an outer diameter of the insulation pipe is less than an inner diameter of the first tube portion of the insulation connection tube and the first tube portion of the insulation connection tube is sleeved and connected to the outer wall of the first end of the insulation pipe.

13. The insulation assembly of claim 1 , further comprising an end cover mounted on the second end of the insulation pipe.

14. The insulation assembly of claim 13 , wherein an insulation gas of an insulation liquid is filled in an inner space of the insulation pipe.

15. The insulation assembly of claim 13 , further comprising a wire connection bar mounted on a top wall of the end cover.

16. The insulation assembly of claim 15 , further comprising a shielding ring mounted on the top wall of the end cover around the wire connection bar.

17. The insulation assembly of claim 1 , further comprising a shielding sleeve disposed on the insulation base and extending into the insulation connection tube and/or the insulation pipe.

18. The insulation assembly of claim 17 , wherein a slot is formed in a bottom surface of the insulation flange and a flange of the shielding sleeve fits in the slot of the insulation flange.

19. The insulation assembly of claim 1 , wherein the insulation base and the insulation pipe are formed of a same insulation material.

20. The insulation assembly of claim 1 , wherein the insulation base is a fiber material impregnated with a curable agent.

21. The insulation assembly of claim 20 , wherein the fiber material is a man-made fiber or a natural plant fiber.

22. The insulation assembly of claim 21 , wherein the man-made fiber is at least one of glass fiber, Kevlar fiber, aramid fiber, nylon fiber, high density polyethylene fiber, and high or ultra high molecular weight polyethylene fiber.

23. The insulation assembly of claim 20 , wherein the fiber material has a length within a range of 1 millimeter to 300 millimeters.

24. The insulation assembly of claim 20 , wherein the fiber material has a length within a range 10 millimeters to 150 millimeters.

25. The insulation assembly of claim 20 , wherein the fiber material has a length within a range of 5 millimeters to 100 millimeters.

26. The insulation assembly of claim 20 , wherein the curable agent is an epoxy resin.

27. The insulation assembly of claim 20 , wherein the curable agent has bisphenol A epoxy and anhydride.

28. The insulation assembly of claim 1 , further comprising a protection coating layer with flame retardant, anti-current leakage, or anti-aging properties formed on an outer surface of the insulation base.

29. The insulation assembly of claim 28 , wherein the protection coating layer has a silicon rubber and a filler filled in the silicon rubber, the filler is at least one of silicon powder, alumina, zinc oxide, magnesium oxide, boron nitride, titanium dioxide, and iron oxide red.

30. The insulation assembly of claim 28 , wherein a liquid material forming the protection coating layer is capable of being cured and solidified at a temperature equal to or higher than a room temperature.
