Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a manhole cover capable of monitoring the water depth on the ground. Background Art

[0002] A manhole cover is a cover that covers the wellhead or underground pipe, usually made of materials such as metal, concrete or plastic. Its main function is to cover the openings of underground pipes, wells or other facilities to prevent people, vehicles or other objects from accidentally falling in or causing damage. The design of the manhole cover usually takes into account factors such as bearing the weight of vehicles, preventing slipping, and preventing foreign objects from entering the pipe.

[0003] After searching, a sewer manhole cover with anti-blocking function for municipal roads with publication number CN212742831U is found, which includes a mounting frame, a circular plate, a mounting groove and a manhole cover body. Both ends of the manhole cover body are provided with cavities, a mounting groove is provided at the central position of the manhole cover body, and slide grooves are symmetrically provided on the inner side of the mounting groove. Slide blocks are provided inside the slide grooves, and circular plates are transversely provided between the slide blocks. Through holes are evenly provided on the circular plates, and a rectangular groove penetrating the circular plates is provided at the central position of the circular plates, and hinged plates are symmetrically hinged at the bottom ends of the rectangular grooves. This scheme accelerates rainwater to enter the sewer by vibrating the circular plates up and down. On the other hand, the vertical rods provided under the circular plates can be used to eject the stains inside the through holes, thereby avoiding blockage of the through holes. However, the above technical scheme still has the following deficiencies when actually used:

[0004] When rainwater flows into the pipe through the manhole cover, larger garbage in the water, such as plastic bags, will remain on the manhole cover. After a period of accumulation, the garbage may cover the opening on the manhole cover. The prior art uses a circular plate that vibrates up and down to push the garbage upward, but when the circular plate moves downward, the garbage will continue to cover the water inlet, so that rainwater cannot flow into the pipe smoothly and in time, water will accumulate on the ground, affecting traffic and pedestrian passage. Long-term water accumulation may also cause flooding of the road surface and surrounding buildings.

[0005] Therefore, it is necessary to design a manhole cover that can monitor the ground water depth to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5A manhole cover capable of monitoring the water depth on the ground comprises a manhole cover 1, a plurality of water outlets 2 are opened on the manhole cover 1, a water level monitoring sensor 3 is embedded on the manhole cover 1, the water level monitoring sensor 3 is connected to a remote receiving end, and can transmit the water level data on the ground to the receiving end, so that when the staff finds that the water level on the ground is abnormal, they can rush to repair it in time, deal with the water accumulation problem in time, and reduce the public loss caused by the water accumulation problem. Two fixed plates 4 are fixedly connected to the bottom of the manhole cover 1, and a fixed ring 5 is correspondingly arranged under each water outlet 2. A plurality of rotating columns 6 are fixed on the fixed ring 5, and some rotating columns 6 pass through the inside of the water outlet 2. A moving component for driving the fixed ring 5 to move is provided between the two fixed plates 4, and an injection component is also provided between the two fixed plates 4.

[0025] Reference Figure 3 The moving assembly includes a motor 10 fixedly connected to the side wall of one of the fixed plates 4, a reciprocating screw 8 is axially connected to the end of the output shaft of the motor 10, and the end of the reciprocating screw 8 away from the motor 10 is rotatably connected to the side wall of the other fixed plate 4, and a sliding rod 7 is fixedly connected between the two fixed plates 4. A moving frame 9 is slidably sleeved on the sliding rod 7, the reciprocating screw 8 passes through the side wall of the moving frame 9, and the reciprocating screw 8 is threadedly connected to the moving frame 9, and a rotating shaft 11 is rotatably connected between the moving frames 9, and all the fixed rings 5 ​​are fixedly sleeved on the rotating shaft 11. By setting the moving assembly, the rotating column 6 can push garbage during the horizontal movement process to ensure the smooth flow of the sewer 2. The moving assembly also includes a rotating part.

[0026] Reference Figure 2 The rotating part includes a rack 13 fixedly connected to the bottom of the manhole cover 1, one end of the rotating shaft 11 passes through the side wall of the movable frame 9, and a gear 12 is fixedly sleeved on the rotating shaft 11, and the gear 12 and the rack 13 are meshed with each other. Under the transmission action of the gear 12 and the rack 13, the rotating column 6 rotates while moving horizontally, so that the rotating column 6 will hit the bottom of the garbage during rotation, which helps to move or roll the garbage.

[0027] Reference Figure 2 and Figure 5The jet assembly includes two air bags 14, which are fixedly connected to two opposite side walls of the mobile frame 9, respectively. The air bags 14 are fixed to the fixed plate 4, and an air inlet pipe 16 and an air outlet pipe 17 are connected to the air bags 14. Both the air inlet pipe 16 and the air outlet pipe 17 are provided with a one-way valve 18. The flow limiting directions of the two one-way valves 18 are opposite. Under the action of the one-way valve 18, when the air bag 14 is squeezed, the internal air can only be discharged through the air outlet pipe 17, and when the air bag 14 is stretched, the outside air can only enter the air bag 14 through the air inlet pipe 16. The two air bags 14 can continuously supply air to the rotating column 6. The rotating column 6 is tubular, and the interior of the rotating shaft 11 is hollow. The interior of the fixed ring 5 is provided with a number of connecting cavities 19, the same number as the rotating column 6. The rotating column 6 is connected with the interior of the rotating shaft 11 through the connecting cavities 19. A rotating joint 15 is provided at one end of the rotating shaft 11. The air outlet pipe 17 is connected with the interior of the rotating shaft 11 through the rotating joint 15. The air in the rotating column 6 can be blown to the bottom of the garbage, which is helpful for pushing and rolling the garbage and improving the cleaning efficiency.

[0028] Reference Figure 5 The rotating column 6 is made of rubber, which is elastic and can be deformed. In this way, when the rotating column 6 is pushed to clean up garbage, pedestrians or vehicles will not be injured when they come into contact with the rotating column 6. When there is no water accumulation, the rotating column 6 moves to the bottom of the manhole cover 1 and is staggered from the drain port 2. This prevents the rotating column 6 from being extended from the drain port 2 for a long time and being worn, thereby extending the service life of the rotating column 6.

[0029] Reference Figure 3 The cross section of the movable frame 9 is a U-shaped structure. When the rotating column 6 rotates, the movable frame 9 will not generate resistance to the rotating column 6.

[0030] The specific working principle of the utility model is as follows:

[0031] When garbage covers the sewer outlet 2, the accumulated water on the ground is difficult to be discharged into the pipe smoothly. At this time, the water level monitoring sensor 3 will detect that the ground water level continues to rise, remains unchanged, or drops very slowly. These abnormal data will be remotely transmitted to the receiving end. At this time, the staff remotely starts the motor 10. The output shaft of the motor 10 rotates to drive the reciprocating screw 8 to rotate. Under the guidance of the slide bar 7, the rotation of the reciprocating screw 8 will not drive the moving frame 9 to rotate, but makes the moving frame 9 move horizontally. The moving frame 9 can drive the fixed ring 5 and the rotating column 6 to move together. During the movement of the rotating column 6, the garbage can be pushed to one side, thereby preventing the blockage of garbage and maintaining the smooth flow of rainwater.

[0032] Furthermore, in the above process, the movement of the moving frame 9 drives the rotating shaft 11 to move. Under the transmission action of the gear 12 and the rack 13, the rotating shaft 11 rotates while moving horizontally, so that the fixed ring 5 and the rotating column 6 rotate. The rotation of the rotating column 6 can further hit and push the garbage, thereby preventing rainwater from accumulating on the ground to cause traffic difficulties or flooding of buildings, and reducing the damage caused by rainwater.

[0033] Furthermore, during the horizontal movement of the mobile frame 9, when the mobile frame 9 moves toward one side, the air bag 14 on that side will be squeezed, and the air in the air bag 14 will be squeezed into the air inlet and outlet pipes 17, and then enter the connecting chamber 19 through the rotating shaft 11, and finally be ejected from one end of the rotating column 6, while the air bag 14 on the other side will be in a negative pressure state, and the outside air will enter the air bag 14 through the air inlet pipe 16. Conversely, when the mobile frame 9 moves toward the other side, the air in the air bag 14 on the other side will be ejected through the rotating column 6, and the outside air will enter the corresponding air bag 14, and the step will be repeated in this way. During the movement of the mobile frame 9, air will be continuously ejected from the rotating column 6. On the one hand, the air in the rotating column 6 can be blown to the bottom of the garbage, which helps to push and roll the garbage. On the other hand, since the rotating column 6 is elastic, the flowing air can support the rotating column 6, increase the carrying capacity of the rotating column 6 for garbage, thereby improving the efficiency of garbage cleaning as a whole and ensuring the water flow capacity of the manhole cover 1.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
