Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power pipeline corridors, in particular to an underground power pipeline corridor. Background Art
[0002] Underground power pipeline corridors are public tunnels built underground in cities for the centralized laying of municipal pipelines such as electricity, communications, radio and television. A large number of cables will be laid inside the pipeline corridors according to the needs of power supply or communication.
[0003] At present, underground power pipelines are located below the ground, and there are not only a large number of cables laid inside the ducts, but also many types and categories of cables. However, all these cables are exposed inside the underground pipelines. Once an accident occurs due to a malfunction of individual cables, it will cause safety hazards to the remaining cables. At the same time, the complexity of cables of the same category is not conducive to management after wiring.
[0004] Regarding the protection of cables in underground utility tunnels, how to provide an independent protective sub-tube corridor for the same type of cables in underground power utility tunnels is a technical difficulty that needs to be solved. Utility Model Content
[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.
[0006] To this end, the technical solution adopted in this utility model is:
[0007] An underground power pipe gallery comprises a clamping mechanism, a cable support mechanism installed on the clamping mechanism, and a pipe gallery mechanism installed in the clamping mechanism, wherein the clamping mechanism comprises a base, a first jacket movably installed on one side of the outside of the base, a second jacket movably installed on the other side of the outside of the base, and two groups of combined bolts installed in the first jacket and the second jacket, the cable support mechanism comprises a protective ring buckle located on the outside of the first jacket and the second jacket, a positioning clamp movably installed in the middle of the inner cavity of the protective ring buckle, and a reinforcing sleeve installed in the inside of the protective ring buckle, and the pipe gallery mechanism comprises an anti-skid outer tube installed on the inside of the first jacket and the second jacket, two ring pads fixedly installed on the outside of the anti-skid outer tube, two pressurized powder spray cans fixedly installed on the top of the anti-skid outer tube, and a sealing gasket connected to the bottom end tube of the pressurized powder spray can.
[0008] In a preferred example, the utility model can be further configured as follows: the base is made of stainless steel material, and transverse holes are provided in the end plates on both sides of the base, and reinforcing bolts are movably installed in the transverse holes, the first jacket and the second jacket are made of insulating plastic, and the tops of the first jacket and the second jacket are provided with two transverse grooves adapted to be clamped on the slider at the bottom of the base.
[0009] By adopting the above technical solution, the combined first jacket and the second jacket are fixed by two sets of combined bolts. At this time, the tops of the first jacket and the second jacket after fixation can provide a horizontal groove for adapting clamping for the slider at the bottom of the base. After the base is fixed to the inner wall of the underground power pipeline corridor by reinforced bolts, multiple anti-slip outer tubes laid along the inner wall of the pipeline corridor can provide independent protection cavities for cables of the same category.
[0010] In a preferred example, the utility model can be further configured as follows: the protective ring buckle is made of rubber material, and four through holes are opened in the middle of the protective ring buckle.
[0011] By adopting the above technical solution, when the cable passes through the inner cavity of the anti-slip outer tube and penetrates to the outside, the protective ring buckle can be quickly assembled along the gap between the two adjacent anti-slip outer tube ports. When the anti-slip outer tube and the protective ring buckle are connected, flames appear inside the anti-slip outer tube and the protective ring buckle. The soft protective ring buckle is deformed at the moment of encountering the flame, and the pressurized powder spray can will also spray powder towards the inner cavity of the anti-slip outer tube.
[0012] In a preferred example, the utility model can be further configured as follows: the positioning clamp is composed of a flame retardant gasket and four clamping rods installed on the outside of the flame retardant gasket, the reinforcing sleeve is made of silicone material, and the reinforcing sleeve passes through one end of the inner cavity of the protective ring buckle and is provided with a hole adapted to be clamped on the clamping rod.
[0013] By adopting the above technical solution, four reinforcing sleeves are inserted into the inside of the protective ring buckle. At this time, the four clamping rods in the positioning clamp can be positioned and clamped by the four reinforcing sleeves, and the flame-retardant gaskets fixed in the middle of the four clamping rods can provide suspended support for cables of the same type while setting a cavity for guiding powder spraying in the inner cavity of the anti-slip outer tube. Once the cable suddenly ignites due to an accident, the pressurized powder spray tank can quickly spray dry powder into the inner cavity of the anti-slip outer tube.
[0014] In a preferred example, the utility model can be further configured as follows: the inner wall of the anti-slip outer tube is coated with a flame retardant paint surface, and the outer wall of the anti-slip outer tube is coated with an insulating paint layer.
[0015] By adopting the above technical scheme, the combined protective ring buckle and positioning clamp are used to position and support cables of the same category. When cables of the same category are installed in the middle of the inner cavity of the anti-slip outer tube, the cables suspended in the middle of the inner cavity of the anti-slip outer tube can be protected. Once a fire occurs in the cables, the multiple independent anti-slip outer tubes can prevent the remaining equipment in the underground power corridor from being disturbed by the fire in the anti-slip outer tube.
[0016] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:
[0017] 1. The utility model assembles cables of the same category in batches inside each sub-pipeline corridor, and the cables of the same category can be clamped in the middle of the inner cavity of the anti-slip outer tube by positioning clamps. When an emergency occurs to the cables of the same category, the cables in the independent sub-pipeline corridor can be extinguished by the dry powder in the inner cavity of the pressurized powder spray can at the moment of spontaneous combustion. While ensuring that the underground power pipe corridor is not disturbed, a safe working environment can be provided for the subsequent emergency repair of the cables.
