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 level of a pipeline. Background Art

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] After searching, the publication number CN219886942U is a kind of intelligent manhole cover device for sewage pipes with liquid level monitoring function, including a mounting seat, the upper end of the mounting seat is rotatably connected to the manhole cover, the top of the manhole cover is fixedly connected to a solar power generation panel, the bottom of the manhole cover is fixedly connected to a mounting box, the installation box is provided with a battery, a controller and a signal transmission device, the controller and the signal transmission device are located on one side of the battery, and a filter barrel is provided inside the mounting seat. This solution enables the manhole cover to monitor the water level and transmit the information remotely to an external receiving end, so as to grasp the situation in real time, and solves the problem that the existing manhole cover does not have the intelligent monitoring function. However, the above technical solution still has the following shortcomings when it is actually used:

[0004] In rainy weather, a large amount of rainwater inside the well pipe cannot be discharged in time, which will cause the gas inside the pipe to compress. At this time, the squeezed air will choose to release to the place with lower pressure, which will cause the manhole cover to jump up and down. When the inside of the pipe is full of rainwater, the rainwater will also generate pressure on the manhole cover, pushing the manhole cover and spraying it out. Secondly, in summer, due to weather reasons, the temperature in the pipe rises, various gases are mixed, and the temperature difference between the inside and outside caused by rainwater causes some gases to generate a certain amount of kinetic energy due to temperature changes, causing them to be released quickly in a local area. The air pressure changes drastically, which can also cause the manhole cover to jump. Although the above-mentioned prior art can monitor the water level in the pipeline, the manhole cover is generally placed directly on the mounting seat or hinged on the mounting seat. When the manhole cover is subjected to the pressure caused by the above reasons, the manhole cover may jump, flip or shift, which will bring safety hazards to pedestrians and vehicles. Especially in dim light conditions, pedestrians may not be able to detect the movement or flipping of the manhole cover in time, which may easily lead to accidents. In addition, for the manhole cover placed directly on the mounting seat, when it is strongly impacted by air or water flow, the manhole cover may jump upward to a high height, which may cause harm to pedestrians during the falling process.

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

DETAILED DESCRIPTION

[0024] 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.

[0025] Reference Figure 1-5, a manhole cover capable of monitoring the water level of a pipeline, comprises a mounting seat 1 and a manhole cover 2 arranged on the mounting seat 1, a water level monitoring sensor 3 is arranged at the bottom of the manhole cover 2, and the water level monitoring sensor 3 is connected to a remote receiving end. The specific principles and internal structures are all prior arts, and no further elaboration is made here. When the water level monitoring sensor 3 detects an abnormal water level, these monitoring data will be transmitted to the receiving end, so that the staff can dredge or repair the pipeline in time, and because the air flow contains water, when the air flow or water flow impacts upward, the water level monitoring sensor 3 can also monitor the abnormality in the pipeline in time, thereby ensuring the timeliness of the maintenance of the manhole cover 2, a card slot 4 is arranged on the mounting seat 1, a card ring 5 is arranged inside the card slot 4, and a plurality of fixings for fixing the card ring 5 are arranged on the card ring 5, a plurality of connecting components are arranged between the manhole cover 2 and the mounting seat 1, and a warning component for warning pedestrians is also arranged on the manhole cover 2.

[0026] Reference Figure 4 The fixing part includes a control plate 19 arranged above the clamping ring 5. The control plate 19 is in a U-shaped structure, which is convenient for the staff to rotate. A rotating shaft 15 is fixed to the bottom of the control plate 19. The bottom end of the rotating shaft 15 extends to the bottom of the clamping ring 5, and the rotating shaft 15 is rotatably connected to the clamping ring 5. A fixing block 17 is fixedly connected to the side wall of the rotating shaft 15. A control groove 16 adapted to the fixing block 17 is provided on the inner bottom surface of the clamping groove 4. A fixing cavity 18 connected to the control groove 16 is provided inside the mounting seat 1, and the fixing cavity 18 is located below the clamping groove 4. Under the action of the fixing part, the staff can quickly remove the clamping ring 5 from the clamping groove 4, which is convenient for the staff to enter the interior of the pipeline for maintenance work.

[0027] Reference Figure 3 The connecting assembly includes a connecting groove 6 provided on the clamp ring 5, a sleeve 7 is slidably connected inside the connecting groove 6, the top of the sleeve 7 is fixed to the bottom of the manhole cover 2, a push rod 8 is sealed and slidably connected inside the sleeve 7, and the longitudinal section of the push rod 8 is a T-shaped structure, the bottom end of the push rod 8 extends to the outside of the sleeve 7, and the bottom end of the push rod 8 is fixed to the inner bottom surface of the connecting groove 6, the top position of the side wall of the sleeve 7 is connected to an air inlet pipe 13, the air inlet pipe 13 is provided with a one-way valve 14, and the bottom end position of the side wall of the sleeve 7 A connecting pipe 12 is provided for communication, and a one-way valve 14 allows outside air to only enter above the push rod 8 in the sleeve 7. In this way, after the manhole cover 2 moves up, the internal pressure of the sleeve 7 is constant, and the sleeve 7 will not move down. In this way, the sleeve 7 will not fit with the mounting seat 1, so that the gas or water flow in the pipeline can be released in time, which can also prevent the manhole cover 2 from being damaged by excessive pressure. Under the action of the sleeve 7, the manhole cover 2 will not be offset from the pipeline opening in the horizontal direction, thereby preventing pedestrians from falling into the pipeline and reducing safety hazards.

[0028] Reference Figure 1 and Figure 3The warning component includes a placement groove 10 arranged on the manhole cover 2, and a cover plate 11 adapted to the placement groove 10 is provided on the manhole cover 2. An airbag 9 is arranged inside the placement groove 10. When the airbag 9 is in an expanded state, the airbag 9 can be stored in the placement groove 10, and the cover plate 11 can protect the airbag 9 to prevent damage to the airbag 9 caused by vehicles or pedestrians. The top of the airbag 9 is fixed to the bottom of the cover plate 11, and the airbag 9 is connected to the connecting pipe 12. The airbag 9 is in a long strip shape. The height of the airbag 9 will increase after it is inflated. In this way, when the manhole cover 2 moves upward, it can timely warn nearby pedestrians or vehicles to prevent airflow or water flow from causing harm to pedestrians or vehicles.

[0029] Reference Figure 1 The side wall of the cover 11 is provided with a plurality of warning lights 21 distributed at equal intervals. The warning lights 21 can be connected to the water level monitoring sensor 3. After the manhole cover 2 is moved up, pedestrians and vehicles can be reminded in time in a dimly lit environment to reduce safety hazards.

[0030] Reference Figure 5 The bottom of the manhole cover 2 is provided with a groove 20 corresponding to the control board 19, and the control board 19 can be received in the groove 20 to ensure that the manhole cover 2 and the mounting base 1 can fit together.

[0031] The specific working principle of the utility model is as follows:

[0032] When the manhole cover 2 is impacted by airflow or water flow, the manhole cover 2 and the sleeve 7 will move upward, and the sleeve 7 will extend from the connecting groove 6. Since the position of the push rod 8 is fixed, the upward movement of the sleeve 7 causes a negative pressure state to appear at the upper end of the push rod 8, so that the external air can enter the sleeve 7 through the air inlet pipe 13. Under the connection between the push rod 8 and the sleeve 7, the manhole cover 2 will not be separated from the mounting seat 1. Under the action of the one-way valve 14, the air at the top of the push rod 8 will not be discharged. At this time, the internal pressure of the sleeve 7 is constant, so the manhole cover 2 will not reset downward under the action of gravity. At this time, the manhole cover 2 and the mounting seat are connected. 1, so that the gas or water in the pipeline can be discharged in time. Under such a design, the manhole cover 2 will not be staggered with the pipeline to prevent pedestrians from falling into the pipeline. Secondly, the pressure in the pipeline can be released in time to prevent the impact of airflow or water flow from causing harm to pedestrians or vehicles. When the airflow impacts upward, it will carry water. In this way, the airflow or water flow will pass through the water level monitoring sensor 3 when moving upward. The water level monitoring sensor 3 can detect the water level abnormality and remotely transmit the information to the receiving end, so that the staff can also maintain the manhole cover 2 at that place in time;

[0033] Furthermore, in the above process, when the manhole cover 2 is impacted and moves upward, the sleeve 7 is driven upward, and the inner bottom surface of the sleeve 7 squeezes the air in the sleeve 7, so that the air enters the airbag 9 through the connecting pipe 12. After the airbag 9 is inflated, the overall height increases, and a warning light 21 is provided on the cover plate 11, so that pedestrians and vehicles can be reminded in time when an abnormality occurs in the manhole cover 2, thereby reducing safety hazards;

[0034] Furthermore, when the staff needs to enter the pipeline for inspection and maintenance, the staff lifts the manhole cover 2 to create a distance between the manhole cover 2 and the retaining ring 5, and the airbag 9 is also inflated. The upward movement of the manhole cover 2 allows the control panel 19 to be disengaged from the slot 20. Then the staff screws the control panel 19 to rotate the shaft 15 and the fixed block 17. When the fixed block 17 rotates to the bottom of the control slot 16, the staff pulls the control panel 19 upward to move the fixed block 17 into the control slot 16, and then continues to pull up. The retaining ring 5 can be disengaged from the retaining groove 4, so that the manhole cover 2 can be separated from the mounting seat 1, and then the staff can enter the pipeline for inspection and maintenance. The airbag 9 on the separated manhole cover 2 is in an expanded state, which also serves as a warning to the vehicle to prevent the vehicle from causing harm to the maintenance personnel.

[0035] 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.
