Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, in particular to a waterproof handhole well. Background Art

[0002] A handhole well refers to a well built in a building or a municipal project for facilitating cable laying. It is a well that people cannot enter but can only reach in with their hands, which is convenient for threading. Generally, it is mainly made of cement bricks.

[0003] A channel for the entry and exit of cable sleeves is provided on the side of the handhole well. The number of cable sleeves for entry and exit is usually more than two. Inevitably, there are some gaps between the entry and exit channels and the cable sleeves. Rainwater easily enters the handhole well through these gaps, causing water accumulation in the handhole well. Moreover, some rainwater also enters through the poor sealing between the manhole cover and the well body. The cables located in the handhole well are easily damaged after being soaked in rainwater for a long time, resulting in line failures.

[0004] Therefore, at present, a technical solution is needed to solve the technical problems that rainwater often seeps into the interior of the handhole well and the cables in the handhole well are easily damaged after long-term contact with rainwater. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the technical problems that rainwater often seeps into the interior of the handhole well and the cables in the handhole well are easily damaged after long-term contact with rainwater, and to provide a waterproof handhole well.

[0006] The utility model provides a waterproof handhole well, which includes a well body. A cover plate is provided at the top of the well body. A wire-passing window is provided on the side wall of the well body. A partition net is provided inside the well body. The partition net divides the internal space of the well body into two parts, which are a storage area and a water accumulation area from top to bottom in sequence. The partition net is arranged below the wire-passing window.

[0007] When the waterproof handhole well of the utility model is in use, the well body is hoisted to the installation position. The cable sleeve extends into the interior of the well body through the wire-passing window on the side wall of the well body. The incoming cables are placed on the partition net inside the well body. The rainwater seeping into the interior of the well body will continue to fall into the water accumulation area after passing through the partition net, avoiding long-term contact between the rainwater and the cables, playing a role in protecting the cables, and prolonging the service life of the cables.

[0008] Preferably, an annular support plate is provided on the inner wall of the well body, and the partition net is detachably arranged on the annular support plate.

[0009] The detachable installation of the partition net inside the well body is realized, which is convenient for taking out the partition net during use to perform maintenance operations such as cleaning, draining, and plugging the water accumulation area.

[0010] Preferably, an annular frame is arranged at the edge of the partition net, and the annular frame abuts against the annular support plate.

[0011] The annular frame has higher strength relative to the partition net, making the partition net more stable when installed inside the well body.

[0012] Preferably, a submersible pump is provided on the inner bottom wall of the well body. The submersible pump is connected to a liquid discharge pipe. A through hole is provided on the side wall of the well body, and the liquid discharge pipe extends out of the well body through the through hole.

[0013] When there is too much accumulated water inside the well body, the submersible pump can be used to pump the rainwater into the liquid discharge pipe, and then the rainwater is discharged into the sewer or other drainage facilities through the liquid discharge pipe, avoiding the cables being flooded by rainwater due to excessive accumulated rainwater inside the well body.

[0014] Preferably, an elastic washer is provided on the inner wall of the through hole.

[0015] The elastic washer can closely fit with the outer wall of the liquid discharge pipe, forming a seal for the gap between the liquid discharge pipe and the inner wall of the through hole, reducing the infiltration of rainwater.

[0016] Preferably, a controller and a liquid level sensor are further included. The controller is arranged in the storage area, and the liquid level sensor is arranged in the water accumulation area. The liquid level sensor and the submersible pump are respectively electrically connected to the controller.

[0017] The liquid level sensor can monitor the liquid level height in the water accumulation area in real time. When the liquid level height in the water accumulation area reaches the threshold, the liquid level sensor transmits an electrical signal to the controller, and the controller issues an instruction to the submersible pump to pump out the rainwater in the water accumulation area, thus realizing automatic drainage inside the well body.

[0018] Preferably, an annular step surface is provided at the top of the well body, and an annular water stop is provided on the annular step surface.

[0019] The bottom of the annular water stop abuts against the annular step surface, and the top abuts against the cover plate, forming a seal for the gap between the cover plate and the well body, reducing the infiltration of rainwater.

[0020] Preferably, a lifting ring is provided on the outer side wall of the well body.

[0021] It is convenient to hoist the well body through the lifting ring, so as to facilitate the transportation, loading and installation operations of the well body. At the same time, the lifting ring provided on the side wall of the well body will not interfere with the installation of the cover plate, making it more convenient to use.

[0022] Preferably, the wire passing window is set to be circular. A waterproof sleeve is connected outward from the wire passing window. The waterproof sleeve is an elastic material structural member. The waterproof sleeve is set to be trumpet-shaped, and the large end of the waterproof sleeve is connected to the edge of the wire passing window.

[0023] The cable sleeve enters the interior of the well body through the waterproof sleeve. The small end of the waterproof sleeve is tightened on the outer wall of the sleeve, reducing the space for rainwater to enter through the wire passing window, thereby reducing the infiltration of rainwater into the well body interior.

[0024] Compared with the prior art, the beneficial effects of the present utility model are:

[0025] In this application, a partition net is arranged in the handhole well for placing the cables entering the handhole well. The rainwater infiltrating into the well body interior will continue to fall into the water accumulation area after passing through the partition net, avoiding the long-term contact between the rainwater and the cables, playing a role in protecting the cables, and extending the service life of the cables.
