Technical Field
[0001] The utility model relates to the technical field of manhole covers, in particular to a manhole cover with a flood discharge and drainage structure. Background Art
[0002] A manhole cover is a structure used to cover the entrance of a sewer, usually used in roads, sidewalks and other public areas. Its main function is to protect the sewer system. When the rainfall is heavy, the drainage capacity of the manhole cover will be overloaded, causing a large amount of rainwater to accumulate, causing the accumulated water to spread on the road surface and affect vehicle driving.
[0003] China's patent "Safety manhole cover with flood discharge function" authorization announcement number "CN113026918B" When a large amount of water accumulates on the road surface, the staff or external tools pull up the power handle to open the manhole cover and put it in an open state. The expanded manhole cover has a larger discharge hole, thereby increasing the drainage volume and facilitating rapid flood discharge.
[0004] When water accumulates on the road, workers are required to operate the manhole cover on site and make the manhole cover deform completely before drainage can be carried out. However, it is dangerous for workers to operate at the water accumulation site.
[0005] Therefore, a manhole cover with a flood discharge and drainage structure is proposed to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a manhole cover with a flood discharge and drainage structure in order to solve the above-mentioned problem, thereby improving the problem that workers are required to operate the manhole cover on site and make the manhole cover deform before drainage operations can be carried out, but there is a certain risk for workers to operate at the flooded site.
[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a manhole cover with a flood discharge and drainage structure, comprising: a manhole cover body, a water outlet is opened at the top of the manhole cover body; a flood discharge mechanism, which is used to realize automatic flood discharge and is arranged inside the manhole cover body; wherein, the flood discharge mechanism includes a drainage port opened at the top of the manhole cover body, a sealing plate is slidably connected to the inner wall of the drainage port, and a flood discharge component is arranged inside the manhole cover body.
[0008] Preferably, the flood discharge assembly includes a drainage cylinder fixedly connected to the lower end of the inner wall of the drain outlet, a floating plate is arranged inside the drainage cylinder, the bottom end of the floating plate is fixedly connected to a connecting rod, the other end of the connecting rod passes through the drainage cylinder and is fixedly connected to a connecting ring, the upper end of the surface of the connecting ring is fixedly connected to round rods distributed in a ring shape, the top end of the round rods is hinged with a push rod, and the top end of the push rod is hinged to the bottom end of the blocking plate. By utilizing the diameter difference between the through holes at the top and bottom ends of the drainage cylinder, when the water accumulation on the manhole cover body increases, the floating plate moves upward to drive multiple blocking plates to move, so that multiple drainage outlets can perform flood discharge operations. Under the action of the floating plate, the state of the blocking plate can be automatically adjusted according to the water accumulation on the manhole cover body to complete the flood discharge operation, which makes the operation more convenient and improves the practicality of the device.
[0009] Preferably, a circular ring is slidably connected to the upper end of the inner wall of the drain port, a filter plate is fixedly connected to the inner wall of the circular ring, a bellows is fixedly connected to the bottom end of the circular ring, and the bottom end of the bellows is fixedly connected to the top end of the drainage tube. The circular ring uses the filter plate to intercept large impurities in the flowing water during drainage operations to prevent impurities from entering the drainage tube, thereby ensuring the stability of the device during operation, and at the same time uses the bellows to ensure normal drainage operations when the circular ring moves up and down.
[0010] Preferably, the top of the drainage cylinder is fixedly connected with two cylinders, the inner wall of the cylinder is slidably connected with a moving rod, the top of the moving rod is fixedly connected with the bottom of the ring, and a spring is fixedly connected between the bottom of the moving rod and the inner bottom wall of the cylinder. The use of the moving rod and the cylinder is conducive to limiting the upward and downward movement of the ring to prevent the ring from rotating, and at the same time, under the action of the spring, it is conducive to resetting the ring after moving downward.
[0011] Preferably, the inner wall of the drainage cylinder is fixedly connected to two limit rods, the surface of the limit rod is slidably connected to a slider, and the floating plate is fixedly connected between the opposite sides of the two sliders. Under the action of the limit rod and the slider, it is conducive to limiting the up and down movement of the floating plate, thereby improving the stability of the floating plate when moving up and down.
[0012] Preferably, a filter frame is fixedly connected to the inner wall of the manhole cover body, and the filter frame is funnel-shaped. The filter frame is used to filter impurities in the water flow, so that the impurities are retained in the filter frame, and the impurities flow to the lower end of the filter frame under the action of the inclined surface of the filter frame, so that the impurities are gathered, thereby ensuring the normal filtering operation of the filter frame.
[0013] Preferably, a rubber ring is fixedly connected to the top of the ring. The level of the rubber ring is higher than the level of the drain, which is conducive to creating a gap between the garbage gathered above the drain and the cover plate of the manhole cover body, and is conducive to protecting the ring when it moves upward.
[0014] Preferably, the drain port is a through hole, and the number of the drain ports is multiple. Using multiple drain ports is beneficial to improving the effect of draining accumulated water.
[0015] The beneficial effects of the utility model are:
[0016] 1. By utilizing the diameter difference between the through holes at the top and bottom of the drainage tube, when the water on the manhole cover increases, the floating plate moves upward to drive multiple blocking plates to move, so that multiple drainage ports can discharge flood water. Under the action of the floating plate, the state of the blocking plate can be automatically adjusted according to the water accumulation on the manhole cover body to complete the flood discharge operation. There is no need for manual operation by the staff at the water accumulation site, which ensures the safety of the staff and improves the practicality of the device.
[0017] 2. When draining water, the ring uses the filter plate to intercept large impurities in the flowing water to prevent them from entering the drainage tube. At the same time, the ring will move up and down under the impact of the water flow and the action of the spring, and the garbage gathered above the drain outlet will be pushed out, which is conducive to the normal drainage operation of the drain outlet, thereby ensuring the stability of the device during operation.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] When implementing: Figure 1-5 As shown, a manhole cover with a flood discharge and drainage structure includes: a manhole cover body 1, a drain port 2 is opened at the top of the manhole cover body 1; a flood discharge mechanism 3, which is used to realize automatic flood discharge and is arranged inside the manhole cover body 1; wherein the flood discharge mechanism 3 includes a drain port 301 opened at the top of the manhole cover body 1, a sealing plate 302 is slidably connected to the inner wall of the drain port 301, and a flood discharge component 303 is arranged inside the manhole cover body 1.
[0026] The manhole cover body 1 is composed of a cover plate and an installation frame. The drain outlet 301 is opened on the cover plate of the manhole cover body 1, and the inner wall of the cover plate of the manhole cover body 1 is provided with a storage groove matching the sealing plate 302. When the downspout 2 performs normal drainage operations, the sealing plate 302 blocks the drain outlet 301, and the downspout 2 can be used for drainage operations.
[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the flood discharge assembly 303 includes a drainage cylinder 3031 fixedly connected to the lower end of the inner wall of the water outlet 2, a floating plate 3032 is arranged inside the drainage cylinder 3031, a connecting rod 3033 is fixedly connected to the bottom end of the floating plate 3032, the other end of the connecting rod 3033 passes through the drainage cylinder 3031 and is fixedly connected to a connecting ring 3034, a circular rod 3035 is fixedly connected to the upper end of the surface of the connecting ring 3034, a push rod 3036 is hinged to the top end of the round rod 3035, and the top end of the push rod 3036 is hinged to the bottom end of the blocking plate 302. Two limit rods 30313 are fixedly connected to the inner wall of the drainage cylinder 3031, a slider 30314 is slidably connected to the surface of the limit rod 30313, and the floating plate 3032 is fixedly connected between the opposite sides of the two sliders 30314. The drainage outlet 301 is a through hole, and the number of drainage outlets 301 is multiple.
[0028] The diameter of the through hole at the bottom of the drain cylinder 3031 is smaller than the diameter of the through hole at the top of the drain cylinder 3031. The diameter of the through hole at the top of the drain cylinder 3031 is the same as the diameter of the bellows 30312 and the ring 3037. When the drain outlet 2 is performing normal drainage operation, the amount of water flowing into the drain cylinder 3031 through the ring 3037 and the bellows 30312 is small and can flow out through the through hole at the bottom of the drain cylinder 3031. There is a certain distance between the bottom of the floating plate 3032 and the inner bottom wall of the drain cylinder 3031. When the drain cylinder 3031 is drained normally, the water in the drain cylinder 3031 is discharged through the ring 3037 and the bellows 30312. During normal drainage operations, the float 3032 does not move. When the accumulated water on the manhole cover body 1 increases, the amount of water entering the drain cylinder 3031 through the ring 3037 and the bellows 30312 will increase. Since the diameter of the through hole at the bottom of the drain cylinder 3031 is relatively small, the water in the drain cylinder 3031 cannot be discharged in time. When the accumulated water continues to enter the drain cylinder 3031, the amount of water retained in the drain cylinder 3031 will gradually increase, causing the float 3032 to move upward following the water surface.
[0029] When the floating plate 3032 moves upward, it will synchronously drive the connecting rod 3033 to move upward, thereby driving the connecting ring 3034 to move upward. The number of round rods 3035 is the same as the number of blocking plates 302. When the connecting ring 3034 moves upward, it drives the round rod 3035 to move upward. The push rod 3036 is set to be inclined in the initial state. When the round rod 3035 moves upward, it will drive the bottom end of the corresponding push rod 3036 to move upward synchronously. When the bottom end of the push rod 3036 moves upward, the top end of the push rod 3036 will push the blocking plate 302 to move, and make the angle between the round rod 3035 and the push rod 3036 smaller. At the same time, part of the blocking plate 302 enters the storage groove opened on the cover plate of the manhole cover body 1, and at the same time, the blockage of the drain outlet 301 is released. When the drain outlet 301 is unblocked, the accumulated water on the manhole cover body 1 will be discharged through multiple drain outlets 301, completing the flood discharge operation.
[0030] When the accumulated water on the manhole cover body 1 is discharged, the amount of water flowing into the drain cylinder 3031 through the circular ring 3037 and the bellows 30312 will decrease. Under the action of the through hole at the bottom end of the drain cylinder 3031, the amount of water in the drain cylinder 3031 will gradually decrease, so that the float plate 3032 will drop with the liquid level. When the float plate 3032 moves downward, the connecting ring 3034 is driven to move downward synchronously through the connecting rod 3033, so that the connecting ring 3034 drives the push rod 3036 to move downward through the circular rod 3035, so that the push rod 3036 drives the sealing plate 302 to move, thereby realizing the re-sealing operation of the drain outlet 301.
[0031] like Figure 2 , Figure 3 and Figure 4As shown, a circular ring 3037 is slidably connected to the upper end of the inner wall of the drain port 2, a filter plate 3038 is fixedly connected to the inner wall of the circular ring 3037, a bellows 30312 is fixedly connected to the bottom end of the circular ring 3037, and the bottom end of the bellows 30312 is fixedly connected to the top of the drain cylinder 3031. Two cylinders 3039 are fixedly connected to the top of the drain cylinder 3031, a moving rod 30310 is slidably connected to the inner wall of the cylinder 3039, the top of the moving rod 30310 is fixedly connected to the bottom end of the circular ring 3037, and a spring 30311 is fixedly connected between the bottom end of the moving rod 30310 and the inner bottom wall of the cylinder 3039. A rubber ring 305 is fixedly connected to the top of the circular ring 3037.
[0032] When the drain outlet 2 is draining, water will flow into the ring 3037, and flow into the drain cylinder 3031 through the filter plate 3038 and the bellows 30312, and flow out through the through hole at the bottom of the drain cylinder 3031. When the amount of water passing through the filter plate 3038 is large, the filter plate 3038 will drive the ring 3037 to move downward under the impact of the water flow, and the spring 30311 will be squeezed. When the amount of water passing through the filter plate 3038 is small, the ring 3037 will move upward under the action of the spring 30311. Since the water flowing into the drain outlet 2 is in an unstable state, the ring 3037 will move up and down under the impact of the water flow and the action of the spring 30311. When the ring 3037 moves upward, it will push the rubber ring 305 to move upward, thereby ejecting the garbage gathered above the drain outlet 2 to ensure the normal drainage operation of the drain outlet 2.
[0033] A filter frame 304 is fixedly connected to the inner wall of the manhole cover body 1, and the filter frame 304 is funnel-shaped.
[0034] The water flowing in from the downspout 2 and the multiple drain outlets 301 will be filtered through the filter frame 304 and then flow into the drainage pipe below the manhole cover body 1, and the downspout 2 and the drain outlet 301 are opened above the higher end of the filter frame 304. When the water flows out through the drainage tube 3031 and the drainage hole below the downspout 2, it will flow to the higher end of the filter frame 304, and the filter frame 304 will be used to filter the impurities in the water flow so that the impurities are retained in the filter frame 304.
[0035] When the utility model is in use, when the accumulated water on the manhole cover body 1 increases, the water flow entering the drain cylinder 3031 through the circular ring 3037 and the bellows 30312 will increase. Since the diameter of the through hole at the bottom end of the drain cylinder 3031 is small, the water in the drain cylinder 3031 cannot be discharged in time, and the amount of water retained in the drain cylinder 3031 will gradually increase. At this time, the floating plate 3032 moves upward with the liquid surface, and drives the connecting ring 3034 to move upward through the connecting rod 3033, so that the circular rod 3035 moves upward and pushes the push rod 3036, so that the top of the push rod 3036 pushes the blocking plate 302 to move, thereby releasing the blockage of the drain outlet 301. When the drain outlet 301 is unblocked, the accumulated water on the manhole cover body 1 will be discharged through the multiple drain outlets 301, thereby automatically completing the flood discharge operation.
[0036] When the accumulated water on the manhole cover body 1 is discharged, the amount of water flowing into the drain cylinder 3031 through the circular ring 3037 and the bellows 30312 will decrease. Under the action of the through hole at the bottom end of the drain cylinder 3031, the amount of water in the drain cylinder 3031 will gradually decrease, so that the float plate 3032 follows the drop of the liquid level, and drives the connecting ring 3034 to move downward synchronously through the connecting rod 3033, thereby driving the push rod 3036 to move downward, and the push rod 3036 drives the sealing plate 302 to move to complete the automatic sealing operation of the drain outlet 301.
[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
