Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, specifically a manhole cover with a rapid drainage structure. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material 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. The main function of traditional manhole covers is limited to sealing the well opening to prevent people and vehicles from falling in accidentally, and to provide some protection for underground pipeline systems.

[0003] In urban road construction, manholes are often used to transport rainwater from roads and drain it quickly without affecting the roads. Manhole covers are an important part of manholes. Currently, manhole covers are usually installed on the top of the manhole and use drainage holes at the bottom of the manhole cover to drain water from the road. To overcome the above defects, existing technology 1 (Chinese patent application number CN202320747294.9, application date 2023-04-07) provides an easy-drainage manhole cover. This solves the problem that when there is too much water on the road due to heavy rain, the number of holes on the manhole cover is limited, resulting in limited drainage capacity. If workers need to drain the water around the manhole quickly, they need to manually open the manhole cover. However, opening the manhole cover can pose a safety hazard. Vehicles and pedestrians passing by may fall into the manhole if they are not careful. At the same time, since there are many manholes in the city, opening multiple manhole covers greatly increases the labor intensity of workers.

[0004] During use, the aforementioned device cannot enable the manhole cover to drain water quickly, resulting in slippery road surfaces that affect the safety of pedestrians and vehicles. At the same time, the huge water pressure generated by the backflow of water from the manhole cover will impact the manhole cover and its connecting parts, accelerating their aging, deformation, or even damage. Utility Model Content

[0005] The purpose of this utility model is to provide a manhole cover with a rapid drainage structure to solve the problems mentioned in the background art, such as the inability of manhole covers to achieve rapid drainage, resulting in slippery roads, affecting the safety of pedestrians and vehicles, and the huge water pressure generated by backflow of manhole covers, which will impact the manhole cover and its connecting parts, accelerating their aging, deformation and even damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manhole cover with a rapid drainage structure, comprising a base, a manhole cover bolted to the upper surface of the base, a support plate fixedly connected to the inner wall of the base, a fixing block fixedly connected to the upper surface of the support plate, a limiting groove formed inside the manhole cover, a sliding block slidably connected to the surface of the limiting groove, a limiting plate fixedly connected to the surface of the sliding block, and the upper surface of the limiting plate fitting against the lower surface of the manhole cover, an isolation cover fixedly connected to the upper surface of the support plate, a fixing rod fixedly connected to the surface of the isolation cover, and a striking post slidably connected inside the fixing rod.

[0007] Preferably, an electric motor is fixedly connected to the upper surface of the support plate, and a No. 1 rotating shaft is fixedly connected to the output end of the electric motor, and the No. 1 rotating shaft is rotatably disposed inside the fixed block.

[0008] Preferably, a second rotating shaft is fixedly connected inside the limiting plate, and bevel gears are fixedly connected to the surface of the second rotating shaft and the surface of the first rotating shaft. The first rotating shaft passes through the interior of the isolation cover, while the second rotating shaft and the first rotating shaft are rotatably disposed inside the isolation cover.

[0009] Preferably, the manhole cover has a first drainage channel inside, and the first drainage channel is symmetrically distributed about the center of the manhole cover.

[0010] Preferably, the manhole cover has a second drainage channel inside, and the second drainage channel is distributed at equal intervals with respect to the upper surface of the manhole cover.

[0011] Preferably, a connecting rod is fixedly connected to the end of the first rotating shaft, and a push block is fixedly connected to the surface of the connecting rod, and the surface of the push block is arc-shaped.

[0012] Preferably, a connecting plate is fixedly connected to the surface of the striking column, and a spring is fixedly connected to the surface of the connecting plate, with the fixing rod fixedly connected to the other end of the spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the manhole cover with a rapid drainage structure adopts a novel structural design, the specific details of which are as follows:

[0014] This manhole cover with a rapid drainage structure can open the first drainage channel by setting a limiting plate and connecting it to a motor, thus enabling the two drainage channels to work simultaneously. This can quickly disperse accumulated water, reduce the duration and depth of water accumulation on the manhole cover surface, ensure the safety of passage around the manhole, and prevent problems such as backflow of water, thereby improving the practicality and reliability of the manhole cover's drainage function.

[0015] Furthermore, the limiting plate slides on the surface of the limiting groove to prevent excessive offset or misalignment, thereby ensuring a good fit between the manhole cover and the limiting plate and improving the safety of use.

[0016] This manhole cover with a rapid drainage structure, through the connection of a striking column and a spring, allows the striking column to reciprocate by striking the isolation cover. This not only breaks the adhesion between the stains and the surface of the isolation cover, making it easier for stain particles to fall off the surface of the isolation cover, but also ensures that the device can operate continuously and stably, so that the isolation cover always maintains a good protective and working condition.

[0017] Furthermore, it reduces the potential risk of malfunctions caused by issues such as dirt accumulation, and improves the overall reliability of the device operation.

[0018] (3) The manhole cover with a fast drainage structure has a base as the basic support part of the whole device, which bears the weight of the upper manhole cover, support plate and limiting plate. The support plate is fixedly connected to the inner wall of the base, which on the one hand strengthens the structural strength of the base, and on the other hand provides a stable attachment base for fixing the motor.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: By connecting the base 1, the manhole cover 2, and the support plate 10, the stability of the device is improved, such as... Figures 1-2 As shown:

[0029] The device includes a base 1, a manhole cover 2 bolted to the upper surface of the base 1, a support plate 10 fixedly connected to the inner wall of the base 1, a fixing block 9 fixedly connected to the upper surface of the support plate 10, a limiting groove 13 inside the manhole cover 2, a sliding block 12 slidably connected to the surface of the limiting groove 13, a limiting plate 11 fixedly connected to the surface of the sliding block 12, and the upper surface of the limiting plate 11 fitting against the lower surface of the manhole cover 2. An isolation cover 14 fixedly connected to the upper surface of the support plate 10, a fixing rod 17 fixedly connected to the surface of the isolation cover 14, and a striking post 18 slidably connected inside the fixing rod 17.

[0030] The stability of the device is improved by connecting the base 1, the manhole cover 2, and the support plate 10. The base 1 serves as the basic support of the entire device, bearing the weight of the manhole cover 2, the support plate 10, and the limiting plate 11. The support plate 10 is fixedly connected to the inner wall of the base 1, which on the one hand strengthens the structural strength of the base 1, and on the other hand provides a stable attachment base for fixing the motor 5. At the same time, the isolation cover 14 plays a role in isolation and protection, improving the protection of the first rotating shaft 6, the second rotating shaft 7, and the bevel gear 8, and avoiding interference from external dust, debris, and rainwater. A limiting groove 13 is opened inside the manhole cover 2. Through the rotation of the second rotating shaft 7, the limiting plate 11 is driven to slide on the surface of the limiting groove 13, preventing excessive offset and misalignment, thereby ensuring a good fit between the manhole cover 2 and the limiting plate 11, improving the safety of use. At the same time, the precise limiting effect ensures that the relative movement between the components is within a reasonable range, reducing wear caused by excessive friction and unreasonable collisions, and helping to extend the service life of the manhole cover 2 and the limiting plate 11.

[0031] In Example 2, unlike Example 1, the rapid drainage effect of the manhole cover 2 is improved by connecting the motor 5, the limiting plate 11, and the second rotating shaft 7. Figures 3-5 As shown:

[0032] A motor 5 is fixedly connected to the upper surface of the support plate 10, and a first rotating shaft 6 is fixedly connected to the output end of the motor 5. The first rotating shaft 6 is rotatably set inside the fixed block 9. A second rotating shaft 7 is fixedly connected inside the limiting plate 11. A bevel gear 8 is fixedly connected to both the surface of the second rotating shaft 7 and the surface of the first rotating shaft 6. The first rotating shaft 6 passes through the interior of the isolation cover 14. At the same time, the second rotating shaft 7 and the first rotating shaft 6 are rotatably set inside the isolation cover 14. A first drainage groove 3 is opened inside the manhole cover 2, and the first drainage groove 3 is symmetrically distributed about the center of the manhole cover 2. A second drainage groove 4 is opened inside the manhole cover 2, and the second drainage groove 4 is evenly distributed about the upper surface of the manhole cover 2.

[0033] When the motor 5 rotates, it drives the first rotating shaft 6 at the output end to rotate. The bevel gear 8 connects the first rotating shaft 6 and the second rotating shaft 7. At the same time, a limiting plate 11 is installed on the surface of the second rotating shaft 7, so that the motor 5 drives the limiting plate 11 to rotate. When it is necessary to drain the manhole cover 2 quickly, the motor 5 drives the limiting plate 11 to rotate, so that the first drainage channel 3 is opened. At this time, sewage can flow in not only from the second drainage channel 4, but also from the first drainage channel 3, which improves the drainage efficiency of the manhole cover 2. Whether in some low-lying areas or special areas prone to water accumulation, it can better cope with complex and changeable rainfall conditions with its rapid drainage capability, ensuring smooth drainage of the manhole opening, improving the practical value and application range of the device. In addition, the mode of the two drainage channels working simultaneously can quickly disperse the accumulated water, reduce the duration and depth of water accumulation on the surface of the manhole cover 2, ensure the safety of passage around the manhole opening, and prevent the occurrence of problems such as backflow of water, thus improving the practicality and reliability of the drainage function of the manhole cover 2.

[0034] In embodiment three, unlike embodiment two, by connecting the spring 20, push block 16, and striking post 18, the residue of dirt on the surface of the isolation cover 14 is reduced, making the isolation cover 14 more effective in protecting the internal parts. Figures 6-7 As shown:

[0035] A connecting rod 15 is fixedly connected to the end of the first rotating shaft 6, and a push block 16 is fixedly connected to the surface of the connecting rod 15. The surface of the push block 16 is arc-shaped. A connecting plate 19 is fixedly connected to the surface of the striking post 18, and a spring 20 is fixedly connected to the surface of the connecting plate 19. A fixing rod 17 is fixedly connected to the other end of the spring 20. As the first rotating shaft 6 rotates, the connecting rod 15 on the surface of the first rotating shaft 6 drives the push block 16 to rotate. When the push block 16 contacts the striking post 18, the striking post 18 slides towards the surface of the isolation cover 14. At the same time, the spring 20 is installed on the surface of the connecting plate 19, thereby realizing the reciprocating striking of the isolation cover 14 by the striking post 18. The repeated tapping of the surface 4 causes the isolation cover 14 to vibrate continuously. This vibration has a good cleaning effect on the stains attached to the surface of the isolation cover 14, which can break the adhesion between the stains and the surface of the isolation cover 14, making it easier for the stain particles to fall off the surface of the isolation cover 14. This effectively reduces the residue of stains, keeps the isolation cover 14 clean, better performs its protective function for internal parts, extends the service life of the isolation cover 14 and internal parts, and ensures that the device can operate continuously and stably, and always maintain a good protective and working condition. This reduces the potential failure risk caused by stain accumulation and other problems, and improves the overall reliability of the device.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
