Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a protection structure for municipal water supply and drainage manhole covers. Background Technique

[0002] The current drainage manhole covers in cities can only meet the transportation of ordinary rainwater and are prone to blockage. When encountering heavy rain, ordinary manhole covers cannot meet the drainage of rainwater, which easily leads to urban waterlogging. However, if the manhole covers are completely opened for drainage, it is very easy to cause danger. The Chinese patent with the publication number CN213741241U discloses a damage protection device for a stainless steel manhole cover: the pull net of this patent is connected to the ring through a locking device and a cross hook. The locking device can not only fix the cross hook inside the ring, but also the insertion plate and the waterproof layer in the locking device can prevent rainwater from eroding the connection between the protection component and the ring, facilitating subsequent maintenance.

[0003] However, the above-mentioned existing technical solutions still have the following defects:

[0004] The existing manhole cover protection device is protected by a pull net, which is not firm enough. When the manhole cover is damaged or opened, no warning can be given through a protection structure set at the manhole cover, resulting in poor protection effect and great potential safety hazards. Content of the Utility Model

[0005] The purpose of the utility model is to provide a protection structure for municipal water supply and drainage manhole covers. By setting a protection fence, it can rise when the manhole cover is opened or washed away, playing a role in protection and warning. The hydraulic push rod drives the connecting ring to rise, so that the support rod and the annular pipe rise from inside the manhole cover, surrounding the manhole cover, reminding vehicles and pedestrians to pay attention to safety, with good protection effect. And by setting a light strip inside the annular pipe, the lighting of the light strip can play a warning role, further reminding vehicles and pedestrians not to approach the manhole cover, solving the problems in the existing technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a protection structure for municipal water supply and drainage manhole covers, including a manhole seat and a manhole cover. A manhole cover is arranged inside the manhole seat. A protection net plate is arranged at the lower end of the manhole cover. An installation ring is arranged at the lower end of the protection net plate and is fixedly arranged on the inner wall of the manhole seat. A hook groove and an annular groove are respectively arranged inside the manhole cover. A U-shaped rod is arranged at the bottom of the manhole cover. A protection fence is also arranged inside the manhole seat.

[0007] Preferably, the protection fence includes an annular pipe, and the annular pipe is located in the annular groove. The annular pipe is a transparent pipe and is provided with a light strip inside.

[0008] Preferably, a support rod is fixedly arranged at the lower end of the annular pipe, and the bottom end of the support rod is fixedly connected with a connecting ring, and the connecting ring is located below the mounting ring.

[0009] Preferably, a fixing ring is arranged below the connecting ring, and the fixing ring is fixedly arranged on the inner wall of the well seat, and the connecting ring is connected with the fixing ring through a hydraulic push rod.

[0010] Preferably, the protective net plate comprises an outer frame, a support frame is fixedly arranged on the inner wall of the outer frame, and a rectangular groove is formed inside the support frame.

[0011] Preferably, a positioning rod is arranged at the bottom of the outer frame, and a positioning groove adapted to the positioning rod is formed at the top of the mounting ring.

[0012] Preferably, a housing is fixedly arranged on the inner wall of the mounting ring, a cylinder is arranged inside the housing, and a pneumatic push rod of the cylinder extends to the outside of the housing and is connected with a limiting rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. By arranging the protective fence, the utility model can rise when the manhole cover is opened or washed open, playing a role in protection and warning. The hydraulic push rod drives the connecting ring to rise, so that the support rod and the annular pipe rise from the manhole cover, enclosing the manhole cover, reminding vehicles and pedestrians to pay attention to safety, with good protection effect. And by arranging a light strip inside the annular pipe, the lighting of the light strip can play a warning role, further reminding vehicles and pedestrians not to approach the manhole cover.

[0015] 2. By arranging the protective net plate, the reliability of the manhole cover is increased, avoiding accidents such as pedestrian casualties and vehicle damage caused by the lack of protective structure in the well seat after the manhole cover is damaged or opened, ensuring the safety of pedestrians and vehicles passing by.
