Description

Technical Field

[0001] The present application relates to the field of handhole wells, and in particular to a combined SMC handhole well. Background Art

[0002] A manhole well refers to a well built in construction or municipal engineering to facilitate the laying of cables. It is a well that can only be entered by hands and cannot be entered by people. In order to facilitate the threading of cables, it is generally made of cement bricks. There are also handhole wells prefabricated with high-strength materials.

[0003] Prefabricated hand hole wells can be directly placed in designated locations during construction. However, because the number of cables and threading positions are different in different wiring scenarios, such hand hole wells are usually prefabricated into a closed universal box, and no holes for threading are reserved on the side walls of the box. This makes it convenient for the construction party to open corresponding holes according to the on-site cable conditions, but it makes the installation process of the hand hole well more cumbersome. Utility Model Content

[0004] In order to improve the problem of troublesome operation during the installation process of the hand hole well, the present application provides a combined SMC hand hole well.

[0005] The present application provides a combined SMC handhole well, which adopts the following technical solution:

[0006] A combined SMC hand-hole well comprises a well seat, a box body connected to the well seat and a well cover covering the box body, a plurality of cable holes for passing cables are arranged at intervals on the surface of the box body, the inner walls of the cable holes are connected to limiting ring capsules, the inner ring of the limiting ring capsules can press against the outer periphery of the cables to form a limit, a plurality of sealing plates are connected to the box body, the sealing plates correspond to and cover the cable holes one by one, and the inner ring of the limiting ring capsules can press against the outer periphery of the sealing plates to form a seal.

[0007] By adopting the above technical scheme, multiple cable holes are distributed at intervals on the outer periphery of the box body. During construction, the sealing plate is driven to separate from the cable hole according to the cable hole corresponding to the on-site cable, so that the cable hole on the box body is opened, and the cable end is passed through the cable hole. The inner circle of the limiting ring bag is pressed against the outer periphery of the cable to form a seal, so that the cable is not easily displaced in the cable hole, thereby improving the stability of the cable installation. At the same time, the outer periphery of other sealing plates is pressed against the inner circle of the limiting ring bag and closes the cable hole, so as to realize the directional opening of the cable hole on the box body. The construction party does not need to open corresponding holes on the outer periphery of the box body according to the situation of the on-site cables, thereby improving the simplicity of operation during the hand hole well installation process.

[0008] Optionally, a limiting ring is fixed on the inner wall of the cable hole, and a limiting groove for the limiting ring to be embedded in the outer periphery of the sealing plate is opened; when the sealing plate is embedded in the cable hole, the limiting ring is embedded in the limiting groove, and the outer wall of the limiting ring presses against the inner wall of the limiting groove to form a limit.

[0009] By adopting the above technical solution, when the sealing plate is embedded in the limiting groove, the inner circle of the limiting ring bag presses against the outer periphery of the sealing plate to form a preliminary limit. At the same time, the limiting ring is embedded in the limiting groove, and the outer periphery of the limiting ring presses against the inner wall of the limiting groove to form a limit, so that the sealing plate is not easy to separate from the cable hole, thereby improving the limiting stability of the sealing plate on the box.

[0010] Optionally, a plurality of air supply channels are provided at intervals on the surface of the box body, and the air supply channels correspond to and are connected to the limiting ring bags one by one. An air supply piston is slidably connected to the inner wall of the air supply channel. When the air supply piston slides toward the limiting ring bag, the air in the air supply channel is driven to enter the inner cavity of the limiting ring bag, and the limiting ring bag is pressurized and expanded and presses against the outer periphery of the cable to form a limit.

[0011] By adopting the above technical solution, when the diameter of the cable needs to be smaller than the inner diameter of the limiting ring bag, the air supply piston is driven to slide on the inner wall of the air supply flow channel toward the limiting ring bag, the air pressure in the air supply flow channel increases, and the air in the air supply flow channel enters the inner cavity of the limiting ring bag. The inner ring of the limiting ring bag is pressurized and expanded and presses against the outer periphery of the cable to form a limit, thereby realizing the applicability of the combined SMC hand hole well to cables of different diameters.

[0012] Optionally, the box surface is provided with a plurality of installation cavities for embedding sealing plates, the installation cavities are connected to the air supply flow channel, the surface of the sealing plate facing the air supply piston is connected with a fixing block, and the surface of the air supply piston is provided with a fixing groove for embedding the fixing block.

[0013] By adopting the above technical scheme, when the sealing plate on the corresponding cable hole is removed according to the on-site cable conditions, a cable hole is provided at the end of the cable, driving the air supply piston to slide on the inner wall of the air supply flow channel toward the direction close to the limiting ring bag, and the air in the air supply flow channel enters the limiting ring bag. The inner ring of the limiting ring bag is pressurized and expanded and pressed against the outer periphery of the cable to form a fixation. At the same time, the sealing plate is embedded in the installation cavity, the installation cavity is connected to the air supply flow channel, the fixing block is embedded in the fixing groove, and the outer wall of the fixing block presses against the inner wall of the fixing groove to form a limit, so that the air supply piston is not easy to deviate on the inner wall of the inflation flow channel, thereby ensuring the limiting stability of the air supply piston on the inner wall of the air supply flow channel.

[0014] Optionally, the sealing plate surface is provided with a fixed cavity for the fixed block to slide, and a sealing elastic member is connected to the sealing plate, one end of the sealing elastic member in the elastic force direction is connected to the inner wall of the fixed cavity, and the other end of the sealing elastic member in the elastic force direction is connected to the surface of the fixed block, and the sealing elastic member has an elastic force that drives the fixed block to slide in a direction away from the fixed cavity, and the end of the fixed block tends to protrude from the surface of the sealing plate.

[0015] By adopting the above technical solution, when the sealing plate is embedded in the cable hole, the inner wall of the cable hole abuts against the end face of the fixed block and drives the fixed block to slide toward the fixed cavity. The end face of the fixed block is flush with the end face of the sealing plate, so that it is not easy to wear between the surface of the fixed block and the inner wall of the cable hole, thereby extending the service life of the combined SMC hand hole well.

[0016] Optionally, a guide surface is provided on the end surface of the fixing block protruding from the sealing plate, and the guide surface is in the shape of an arc protrusion, and the guide surface can abut against the inner wall of the cable hole and guide the fixing block to slide in a direction close to the fixing cavity.

[0017] By adopting the above technical solution, when the sealing plate is embedded in the cable hole, the guide surface abuts against the inner wall of the cable hole and guides the fixed block to slide toward the fixed cavity, thereby reducing the wear between the end face of the fixed block and the inner wall of the cable hole, thereby extending the service life of the combined SMC hand hole well.

[0018] Optionally, a fixed airbag is connected to the inner wall of the fixed groove, and the surface of the fixed airbag can press against the surface of the fixed block to form a limit.

[0019] By adopting the above technical solution, when the fixed block is embedded in the fixed groove, the surface of the fixed airbag is pressed against the outer wall of the fixed block to fix it, making it difficult for the air supply piston to slip on the inner wall of the inflation channel, thereby improving the stability of the inner ring of the limiting ring bag pressing against the outer periphery of the cable.

[0020] Optionally, a fixed piston is slidably connected to the inner wall of the fixed groove, the end face of the fixed piston is flush with the surface of the air supply piston, and the fixed groove is connected to the inner cavity of the fixed airbag.

[0021] By adopting the above technical solution, when the fixed cavity is connected to the fixed groove, the elastic force of the sealing elastic part drives the fixed block to slide in the direction close to the fixed groove, the fixed block abuts the surface of the fixed piston and drives the fixed block to slide in the direction close to the fixed groove, the air pressure in the fixed groove increases, the air in the fixed groove enters the inner cavity of the fixed airbag, the fixed airbag is pressurized and expanded and abuts against the surface of the fixed block to form a limit, so that the fixed block is not easy to shift in the fixed groove, thereby improving the limit stability of the air supply piston in the inflation flow channel.

[0022] Optionally, a reset elastic member is connected to the air supply piston, and the elastic coefficient of the reset elastic member is smaller than the elastic coefficient of the sealing elastic member. One end of the reset elastic member in the elastic force direction is connected to the inner wall of the fixed groove, and the other end of the reset elastic member in the elastic force direction is connected to the surface of the fixed piston. The reset elastic member has the elastic force to drive the fixed piston to slide in the direction away from the fixed groove, and the surface of the fixed piston tends to be flush with the surface of the air supply piston.

[0023] By adopting the above technical solution, when the fixed groove is connected to the fixed cavity, the elastic coefficient of the sealing elastic part is greater than the elastic coefficient of the reset elastic part, and the elastic force of the sealing elastic part drives the fixed block to slide in the direction close to the fixed groove. The surface of the fixed block abuts against the surface of the fixed piston and drives the fixed piston to slide in the direction close to the fixed groove. The air pressure in the fixed groove increases and drives the air in the fixed groove into the inner cavity of the fixed airbag. The fixed airbag is pressurized and expanded and pressed against the outer wall of the fixed block, thereby increasing the pressing force between the fixed block and the fixed airbag.
