Description

Technical Field

[0001] The utility model relates to the technical field of pipeline heat preservation protection, in particular to a protection device. Background Technique

[0002] In the underground coal mine environment, steam, as an effective gasifying agent and heat carrier, plays an important role in gas prevention and control and underground coal gasification mining. Injecting hot steam can increase the desorption rate of methane in the coal seam, thereby improving the efficiency of gas extraction and reducing the risk of gas explosion in coal mine operations. The injection of steam not only promotes the desorption of methane but also uses its heat energy to preheat the coal seam, providing the necessary temperature conditions for underground coal gasification mining. Due to the humid underground environment, the injection of hot steam can, to a certain extent, reduce the environmental humidity and improve the working environment of miners. In the wading section, a large amount of condensed water generated by steam condensation needs to be properly treated to prevent water accumulation from affecting the safety and operation efficiency of the mine.

[0003] The existing steam pipeline heat preservation methods mostly involve laying aluminosilicate fiber product insulation pipe shells, binding them with galvanized steel wires, and wrapping the outer protective layer with aluminum alloy plates. However, most of the existing steam pipeline surfaces fix and install the aluminum alloy plates. When it is necessary to inspect, maintain, and repair the steam pipeline, the aluminum alloy plates on the surface cannot be disassembled conveniently and quickly, thus increasing the maintenance time and cost.

[0031] Embodiment 1

[0032] Referring to Figure 1 - Figure 3 , which is the first embodiment of the present utility model. This embodiment provides a protection device, including a sealing assembly 100, which includes a pipe 101, a first sleeve 102 and a second sleeve 103 used in conjunction with the pipe 101, flanges 104 symmetrically and fixed to the pipe 101 by screws, and an extrusion member 105 used in conjunction with the flanges 104. The tightness between the flanges 104 and the pipe 101 is improved through the extrusion member 105;

[0033] An installation assembly 200, which includes blocks 201 and upper short blocks 202 symmetrically installed on the first sleeve 102, slots 203 symmetrically opened on the second sleeve 103, airbags 204 installed in the slots 203, a limiting member 205 used in conjunction with the upper short blocks 202, through which the first sleeve 102 and the second sleeve 103 are fixed together, and a blocking member 206 used in conjunction with the first sleeve 102 and the second sleeve 103, through which falling rocks in the mine can be prevented from colliding with the first sleeve 102.

[0034] Specifically, the extrusion member 105 includes round blocks 105a symmetrically installed on the pipe 101, sealing rings 105b used in conjunction with the round blocks 105a, chutes 105c symmetrically opened on the pipe 101, and a ring 105d and a first spring 105e arranged on the chutes 105c, enabling the ring 105d to reset through the first spring 105e.

[0035] Further, the sealing ring 105b is located between the round block 105a and the ring 105d. The size of the ring 105d is smaller than that of the sealing ring 105b, and there are several chute 105c and the first spring 105e.

[0036] Further, circular holes are symmetrically formed at the top end of the first sleeve 102, through which the polyurethane foam can be injected. The first sleeve 102 and the second sleeve 103 are connected by a hinge. The inner walls of the first sleeve 102 and the second sleeve 103 do not contact the outer wall of the pipeline 101.

[0037] Operation process: Before use, the flange 104 is installed at both ends of the pipeline 101 through screws. When the flange 104 is installed, one end of the flange 104 will contact the ring 105d. With the installation of the flange 104, the ring 105d will be extruded, causing the ring 105d to move towards the sealing ring 105b, deforming the sealing ring 105b due to extrusion. The gap between the flange 104 and the round block 105a is filled through the deformation, thereby improving the sealing performance. At the same time, the first sleeve 102 and the second sleeve 103 are installed on the pipeline 101 and fixed by the limiting member 205. Then, the polyurethane foam is injected into the interiors of the first sleeve 102 and the second sleeve 103 and on the surface of the pipeline 101 through the circular holes. After filling, the polyurethane foam will overflow from another circular hole at this time. Then, the circular holes are welded and sealed. The injected polyurethane foam plays a role in heat preservation and protection for the pipeline 101.

[0038] Embodiment 2

[0039] Refer to Figure 4 - Figure 5 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the limiting member 205 includes lower short blocks 205a symmetrically installed on the second sleeve 103, a limiting frame 205b slidably installed on the lower short blocks 205a, a plug rod 205c inserted into the limiting frame 205b, grooves 205d symmetrically formed on the plug rod 205c, a placement groove formed on the limiting frame 205b, and a limiting block 205e and a second spring 205f arranged in the placement groove. The second spring 205f enables the limiting block 205e to reset.

[0040] Specifically, the lower short blocks 205a and the upper short blocks 202 are both provided with insertion holes, the diameter of the insertion holes is the same as that of the plug rod 205c, and the limiting block 205e is engaged with one of the grooves 205d, thereby fixing the plug rod 205c.

[0041] Further, one side of the limiting block 205e close to the groove 205d is set to be arc-shaped. The second spring 205f is located between the placement groove and the limiting block 205e, and the size of the clamping block 201 is smaller than that of the clamping groove 203.

[0042] The rest of the structure is the same as that of Embodiment 1.

[0043] Operation process: When installing the first sleeve 102 and the second sleeve 103, first pull the insertion rod 205c upward, so that the insertion rod 205c rises and squeezes the limiting block 205e, causing the limiting block 205e to move deeper into the placement groove. As the insertion rod 205c is pulled up, another groove 205d on the surface of the insertion rod 205c will rise to the position of the limiting block 205e. At this time, the limiting block 205e is reset by the reaction force of the second spring 205f and engages with this groove 205d, thereby fixing the insertion rod 205c. At this time, the insertion rod 205c releases the limit on the lower short block 205a and the upper short block 202, and pushes the limiting frame 205b to one side, causing the limiting frame 205b to release the limit on the upper short block 202. Then, rotate the first sleeve 102 and the second sleeve 103 open through the hinge and sleeved on the surface of the pipeline 101. At this time, merge the first sleeve 102 and the second sleeve 103 again. While merging, the clamping block 201 will insert into the clamping groove 203 and contact the top of the airbag 204. As the clamping block 201 descends, it will squeeze the airbag 204. After the first sleeve 102 and the second sleeve 103 are merged, the deformed airbag 204 fills the remaining gap during the merging process, further improving the sealing performance. At the same time, the lower short block 205a and the upper short block 202 will also contact again. At this time, reset the limiting frame 205b and the insertion rod 205c, and the first sleeve 102 and the second sleeve 103 can be installed on the pipeline 101.

[0044] Embodiment 3

[0045] Refer to Figure 6 - Figure 7 This is the third embodiment of the present utility model. The difference between this embodiment and the above embodiments is that the blocking member 206 includes a collar 206a used in conjunction with the first sleeve 102 and the second sleeve 103, a cross bar 206b installed between the two collars 206a. The collar 206a and the cross bar 206b are both made of metal, threaded rods 206c symmetrically arranged on the collar 206a, and extension plates 206d. The extension plates 206d are fixed by screws, a pressing plate 206e arranged on the threaded rod 206c. A rotating shaft is provided at the connection between the threaded rod 206c and the pressing plate 206e, and a connection block 206f used in conjunction with the extension plate 206d.

[0046] Specifically, the collar 206a is composed of two semi - circles and is connected by a hinge. A buckle is provided at the connection of the two semi - circles. There are several cross - bars 206b, and the cross - bars 206b can block falling rocks, etc. The shape of the abutment plate 206e is arc - shaped and contacts the surfaces of the first sleeve 102 and the second sleeve 103, thereby fixing the blocking member 206.

[0047] Furthermore, a rubber pad is provided on the side of the abutment plate 206e away from the threaded rod 206c, and there are several of them. The rubber pads play a role in increasing friction. The connecting block 206f is installed at the bottom end of the second sleeve 103 by screws. Connecting ports are opened at both ends of the connecting block 206f, and the connecting ports are engaged with the extension plates 206d.

[0048] All other structures are the same as those in Embodiment 2.

[0049] Operation process: When in use, the blocking member 206 can be installed according to the usage scenario. Since the device is in a coal mine shaft, the underground environment may be subject to impacts from rocks, coal blocks or other objects. At this time, rotate the collar 206a through the hinge and sleeved on the surfaces of the first sleeve 102 and the second sleeve 103. Then close the collar 206a and connect it through the buckle. Next, rotate the threaded rod 206c to push the abutment plate 206e to move, so that the abutment plate 206e contacts the surfaces of the first sleeve 102 and the second sleeve 103 to install the collar 206a. At this time, insert the connecting block 206f between the two extension plates 206d, so that the extension plates 206d are engaged with the connecting ports. Then install the extension plates 206d on the second sleeve 103 by screws, which can prevent the blocking member 206 from loosening due to impact. At the same time, the cross - bars 206b can block rocks, coal blocks or other objects from hitting the surfaces of the first sleeve 102 and the second sleeve 103.
