Description

TECHNICAL FIELD

[0001] The utility model relates to valve well technical field especially relates to a valve well prevents water device. BACKGROUND

[0002] In the municipal water supply and drainage system, the valve well is one of the key facilities, used to control the fluid flow in the pipeline. However, in extreme weather conditions (such as heavy rain) or when the drainage system fails, a large amount of rainwater or other liquid can easily accumulate in the valve well, causing the water level to rise rapidly. This water accumulation not only affects the normal function of the valve well, but also can cause equipment damage, sewage overflow, and further pollution and safety hazards to the surrounding environment.

[0003] Currently, common measures to prevent water from rising include installing a drainage pump, setting a vent hole, and strengthening the seal. These methods can alleviate the water accumulation problem to some extent, but they still have shortcomings when facing unexpected situations:

[0004] 1. Traditional water rising prevention devices usually only have one water level sensor to monitor the water level and start the drainage pump. However, when the sensor fails or the drainage pump malfunctions, the system cannot respond in time, which may lead to serious consequences.

[0005] 2. Many existing systems rely on regular manual inspection and maintenance, making it difficult to achieve real-time monitoring and automatic response, especially during unattended situations such as night or holidays, which can easily miss the best opportunity for handling.

[0006] 3. Most existing systems lack multiple protection mechanisms, and once a component fails, the entire system may lose functionality, making it difficult to effectively handle complex conditions. SUMMARY

[0007] To overcome the above-mentioned shortcomings, the technical problem to be solved is to provide a valve well water rising prevention device.

[0008] Technical solution: A valve well water rising prevention device, comprising a valve well, a well cover, a valve pipe, a water pump, a discharge pipe, a water suction pipe, a first water level sensor and a second water level sensor, the well cover with a drainage hole is installed at the top of the valve well, the valve pipe is installed inside the valve well, the water pump is installed on the upper side wall of the valve well, the discharge pipe is connected to the top of the water pump, the discharge pipe penetrates out of the valve well at the upper end, the water suction pipe is connected to the bottom of the water pump, the bottom end of the water suction pipe is adjacent to the bottom of the valve well, the first water level sensor is installed on the lower side of the water suction pipe to monitor the low water level state, the second water level sensor is installed above the first water level sensor to provide a high water level warning, the valve pipe, water pump, first water level sensor and second water level sensor are electrically connected to the remote control system.

[0009] In one of the embodiments, a fixed block and a cover are further included, the fixed block is connected to the water suction pipe near the lower port, and the cover is rotatably connected to the fixed block.

[0010] In one of the embodiments, a torsion spring, a guide frame, a sliding frame and a floating ball are further included, two torsion springs are connected between the cover and the fixed block, a guide frame is connected to the top of the fixed block, a sliding frame is slidably connected to the guide frame, and the floating balls are symmetrically connected to the bottom of the sliding frame, and the sliding frame abuts against the cover when sliding to the lowermost end of the guide frame.

[0011] In one of the embodiments, a limiting block, a frame and a filter screen are further included, the limiting blocks are symmetrically connected to the upper side of the valve well, the frame is slidably inserted between the limiting blocks, and the filter screen is connected to the frame and located below the cover.

[0012] In one of the embodiments, a connecting frame is further included, and the connecting frame is connected to the bottom of the frame and located at the middle of the bottom of the filter screen.

[0013] In one of the embodiments, handles are symmetrically connected to the top of the frame.

[0014] The utility model has the following advantages:

[0015] 1. The utility model designs two water level sensors with different heights, forming a double-layer early warning mechanism. The first water level sensor is used for monitoring the low water level state and can immediately send a signal to the control system when the water level reaches the preset height, triggering the water pump to start draining water. The second water level sensor provides high water level early warning, and when the water level exceeds the set value of the second water level sensor, the second water level sensor will start, issue an alarm and notify maintenance personnel to take emergency measures.

[0016] 2. The double protection mechanism significantly enhances the reliability of the system. Even if one of the water level sensors fails, the other water level sensor can still issue an alarm in time, ensuring that the water accumulation problem can be effectively addressed in any situation and preventing equipment damage and environmental pollution caused by high water level.

[0017] 3. Through the coordinated action of the floating ball, the sliding frame and the torsion spring, the cover is automatically opened and closed. When drainage is needed, the cover is automatically opened. After the drainage is completed, the cover is automatically closed to prevent foreign matter from entering the water suction pipe, prolonging the service life of the equipment.

[0018] 4. The filter screen can effectively capture large particles in the rainwater to prevent them from entering the valve well. The design of the connecting frame guides the rainwater to flow downward along the edge of the filter screen, avoiding direct impact on the valve pipe, protecting the internal components, ensuring smooth water flow discharge and improving the drainage efficiency of the system.

Detailed Implementation

[0025] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0026] Example: A valve well anti-flooding device, such as Figures 1-3 As shown, the system includes a valve well 1, a well cover 2, a valve pipe 3, a water pump 4, a drain pipe 5, a pumping pipe 6, a first water level sensor 7, and a second water level sensor 8. The top end of the valve well 1 is fitted with a well cover 2 equipped with a drainage hole, allowing rainwater to drain naturally while preventing foreign objects from entering. The valve pipe 3 is installed inside the valve well 1, responsible for controlling the opening and closing of the fluid in the pipe and regulating the flow rate. A water pump 4 is bolted to the upper part of the rear side wall inside the valve well 1. The top of the water pump 4 is connected to the drain pipe 5, whose upper end extends out of the valve well 1, ensuring proper drainage. Water can be smoothly discharged to the external environment. The bottom of the water pump 4 is connected to the water pump pipe 6. The bottom end of the water pump pipe 6 is close to the bottom of the valve well 1. The water pumping and discharge are achieved through the water pump pipe 6 and the discharge pipe 5. A first water level sensor 7 for monitoring low water level is installed on the lower side of the water pump pipe 6 by bolts. A second water level sensor 8 for providing high water level warning is installed on the water pump pipe 6 above the first water level sensor 7 by bolts. The valve pipe 3, water pump 4, first water level sensor 7 and second water level sensor 8 are all electrically connected to the remote control system.

[0027] In normal circumstances, the drainage hole on the well lid 2 can effectively drain a small amount of ground rainwater, keeping the valve well 1 dry. When encountering heavy rainfall or drainage system failure, the water level in the valve well 1 begins to rise. Once the water level reaches the height of the first water level sensor 7, the first water level sensor 7 will immediately send a signal to the remote control system. Upon receiving the signal, the remote control system starts the water pump 4, which extracts the accumulated water in the well through the suction pipe 6 and discharges it through the discharge pipe 5, thereby maintaining the water level in the valve well 1 within a safe range. If the first water level sensor 7 fails or the water pump 4 malfunctions (e.g., clogs), causing the accumulated water to not be promptly discharged, the water level will continue to rise until it reaches the second water level sensor 8. When the second water level sensor 8 is triggered, it not only notifies the remote control system to increase the drainage intensity, but also sends an alarm to the maintenance personnel, prompting immediate inspection and repair of the relevant equipment to ensure that the problem is quickly resolved and greater losses are avoided.

[0028] As shown in Figure 3 and Figure 4 , it also includes a fixed block 9, a cover 10, a torsion spring 11, a guide rack 12, a sliding rack 13, and a floating ball 14. The fixed block 9 is connected to the suction pipe 6 near the lower end by a bolt. The cover 10 is rotatably connected to the fixed block 9. In the initial state, the cover 10 blocks the lower end of the suction pipe 6 to prevent debris from entering. Two torsion springs 11 are connected between the cover 10 and the fixed block 9. The guide rack 12 is welded to the top of the fixed block 9. The sliding rack 13 is slidably connected to the guide rack 12. The floating ball 14 is symmetrically connected to the bottom of the sliding rack 13. When the sliding rack 13 slides to the lowermost end of the guide rack 12, it abuts the cover 10. The torsion spring 11 is in a deformed state. The weight of the sliding rack 13 is greater than the elastic force of the torsion spring 11, ensuring that the cover 10 remains closed in the static state.

[0029] When there is no or little accumulated water in the valve well 1, the sliding rack 13 slides to the lowermost end of the guide rack 12 due to its own weight. At this time, the sliding rack 13 is located at the connection point of the cover 10 and the fixed block 9. The sliding rack 13 abuts the cover 10, causing the cover 10 to be in a closed state and preventing the cover 10 from rotating, effectively blocking external debris from entering the suction pipe 6. At this time, the torsion spring 11 is in a deformed state, storing elastic potential energy.

[0030] When the water in the valve well 1 increases and cannot be successfully discharged, the floating ball 14 will float on the water surface as the liquid level rises, and as the liquid level rises further, the floating ball 14 drives the sliding frame 13 to move upwards, and when the sliding frame 13 rises to a certain height, it no longer abuts against the connecting point of the cover 10 and the fixed block 9, and the cover 10 can rotate around the connecting point of the cover 10 and the fixed block 9. At this time, the torsion spring 11 quickly rebounds and resets, pushing the cover 10 to rotate and open, thereby removing the obstruction to the lower end of the water suction pipe 6, ensuring that the water suction pipe 6 can immediately start to suck water in an emergency, avoiding poor drainage caused by the cover 10.

[0031] Once the water level rises to the height of the first water level sensor 7, the control system starts the water pump 4, which discharges the accumulated water in the valve well 1 through the water suction pipe 6. As the water pump 4 operates, the water level in the well gradually decreases, and as the accumulated water is effectively discharged, the liquid level decreases, and the floating ball 14 also decreases, driving the sliding frame 13 to move downwards. When the sliding frame 13 returns to the initial position, it again abuts against the cover 10 and forces the cover 10 to reverse and close by its weight. At this time, the torsion spring 11 is deformed again, re-entering the deformed state, ready for the next response.

[0032] As shown in Figure 2 and Figure 5 , it also includes a limit block 15, a frame body 16, a filter screen 17 and a connecting frame 18. The valve well 1 is symmetrically welded with the limit block 15 on the upper side, and the frame body 16 is slidably inserted between the limit blocks 15. The frame body 16 is symmetrically welded with a handle on the top, which is convenient for the operator to hold the handle and remove the frame body 16 from the limit block 15. The frame body 16 is connected with the filter screen 17, which is located below the well cover 2. When rainwater is discharged downward through the drain hole on the well cover 2, the filter screen 17 can effectively intercept impurities such as leaves and sand, preventing them from entering the valve well 1 and protecting the internal components from pollution and damage. The limit block 15 limits the frame body 16, and when cleaning, the frame body 16 can be easily pulled out from the limit block 15 to clean or replace the filter screen 17. After cleaning, the frame body 16 is reinserted into the limit block 15 to restore its original position. The bottom of the frame body 16 is connected with the connecting frame 18, which is located at the middle position of the bottom of the filter screen 17. The design of the connecting frame 18 can guide the rainwater to flow downward along the edge of the filter screen 17, avoiding the rainwater falling directly from the middle, reducing the impact on the valve body of the valve pipe 3 and providing additional protection.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
