Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a municipal drainage manhole cover. Background Art

[0002] Municipal manhole covers are a kind of covers set up in public places such as urban roads and squares to facilitate the maintenance of road facilities. It is mainly used to cover the facilities such as drainage pipes, cables and ventilation ducts below to protect their normal operation and improve the aesthetics of the city. During the installation of the manhole cover, it is necessary to ensure that the manhole cover is placed horizontally and firmly fixed to prevent it from moving or deforming. After the installation is completed, it is also necessary to use filling materials to reinforce the manhole cover to ensure its stability and load-bearing capacity. Finally, the environment around the manhole cover is tidy and obvious safety warning signs are set. However, with the trampling of vehicles and passers-by above the manhole cover, the manhole cover will inevitably loosen from the base, causing the manhole cover to vibrate after the vehicle passes, thereby making noise and affecting the normal life of roadside residents, so it needs to be improved.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0016] like Figures 1 to 3As shown, a municipal drainage manhole cover comprises a square base 1 and a manhole cover body 2, the side of the base 1 is provided with a hinge seat 11, the side of the manhole cover body 2 is movably connected with the hinge seat 11 through a pin shaft, a locking piece 21 is provided on the manhole cover body 2, a socket 12 is provided at the end of the base 1 corresponding to the locking piece 21, a sealing cover 22 is provided on the outer surface of the manhole cover body 2 corresponding to the keyhole of the locking piece 21, an annular rubber pad 3 is provided on the inner ring of the base 1, and buffer blocks 4 are provided at the four corners of the base 1, the buffer blocks 4 are movably embedded in the base 1 through spring columns, and the side of the buffer block 4 protruding from the base 1 is beveled, the side edge of the manhole cover body 2 is movably abutted against the beveled edge of the buffer block 4, and a fall prevention net 5 is detachably installed in the base 1. Specifically, in this embodiment, the manhole cover body 2 is made of ductile iron, which has high structural strength and low cost. The base 1 is embedded in the road surface base and fixed in the road surface base by concrete and screws. The base 1 and the manhole cover body 1 are designed to be frame-shaped. One end of the manhole cover body 2 is movably connected to the hinge seat 11 of the base 1 through a pin shaft. When the maintenance is convenient, the operator opens and closes the manhole cover body 2. A lock 21 is set on the manhole cover body 2. The lock 21 cooperates with the socket 12 on the edge of the base 1 to close the manhole cover body 2 and the base 1, so as to prevent the manhole cover body 2 from being disassembled and stolen by other personnel, and ensure the safety of the use of the manhole cover body 2. When the municipal maintenance personnel need to open the manhole cover body 2, they only need to insert the key into the corresponding keyhole of the lock 21 to open the manhole cover body 2. At the same time, in order to avoid the keyhole being blocked by debris during use, we set a sealing cover 22 on the outer surface of the manhole cover body 2 to block the keyhole. At the same time, in order to prevent the manhole cover body 2 from being affected by the vibration of vehicles running on the road after a long time of use, it is easy to move vertically and horizontally. Only relying on the pin shaft in the hinge seat 11 and the lock piece 21 and the socket 12 cannot completely offset the vibration, and it is easy to cause damage to the pin shaft and the lock piece 21, reducing their service life. Therefore, we install rubber pads 3 on the inner circle of the base 1 to play a vertical buffering role and reduce the abnormal noise caused by the vibration of the manhole cover body 2. Four buffers are installed at the four corners of the base 1. The cushion block 4 is embedded in the base 1 through the spring column, and the side of the cushion block 4 protruding from the base is beveled. When the manhole cover body 2 is closed, the beveled edge of the cushion block 4 is under the pressure of the manhole cover body 2 and retracts to the side of the base 1. At this time, the spring column is compressed, and the spring force provided by the spring column is used to make the beveled edge of the cushion block 4 press against the four corners of the manhole cover body 2, which can not only offset the horizontal vibration force of the manhole cover body 2 when the vehicle passes by, but also the spring column plays a buffering role, reducing the noise generated by the collision between the manhole cover body 2 and the base 1. Furthermore, in order to prevent passers-by from accidentally stepping on and falling when the manhole cover body 2 is open for drainage, we installed an anti-fall net 5 in the base 1 to play a bottoming role and ensure the safety of passers-by.

[0017] like Figure 2 As shown, a guide rail 41 is provided at the bottom of the buffer block 4, and a slide groove 13 is provided at the four corners of the base 1 corresponding to the guide rail 41. The guide rail 41 cooperates with the slide groove 13 to limit the buffer block 4 so that when it is subjected to pressure from the manhole cover body 2, it can only retract or extend along the direction of the guide rail 41, thereby preventing the buffer block 4 from running off and being misplaced.

[0018] like Figure 3 As shown, the outer surface of the manhole cover body 2 is provided with anti-skid protrusions 23, and the inner surface of the manhole cover body 2 is provided with reinforcing ribs 24. Specifically, the anti-skid protrusions 23 can prevent passers-by from falling when walking by, and the reinforcing ribs 24 are used to improve the structural strength of the manhole cover body 2 to prevent the manhole cover body 2 from being crushed by vehicles and collapsing and deforming.

[0019] like Figure 1 As shown, bolt holes are provided at the four corners of the base 1, and the base 1 is fixed in the road surface base by long bolts to prevent the base 1 from being displaced by vibration.

[0020] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
