Description

Technical Field

[0001] This utility model relates to the field of emergency shut-off device technology, and in particular to an emergency shut-off device that integrates a rainwater well and a shut-off valve. Background Technology

[0002] With the acceleration of urbanization, the importance of stormwater drainage systems in urban infrastructure is becoming increasingly prominent. The increase in paved urban surfaces leads to reduced rainwater infiltration and surges in short-term flow, increasing the pressure on drainage systems. Stormwater wells, as a key component of the drainage system, are responsible for the collection and transport of rainwater. Faced with frequent extreme weather events, traditional stormwater drainage systems face significant challenges, especially in emergencies such as torrential rains and floods. Preventing system overload and overflow, and ensuring urban safety and smooth flow, has become an urgent problem to be solved. Therefore, stormwater well shut-off valves must possess efficient and reliable emergency shut-off functions to prevent flood spread and system damage.

[0003] In existing technologies, most storm drain shut-off valves contain only a single disc and lack a limiting structure. During water flow interruption, if the hydraulic load is too high, the single disc may not be able to withstand the excessive impact force, causing it to rotate in the opposite direction. This can not only lead to emergency shut-off failure but may also cause valve malfunction or damage, thereby reducing the reliability of the system.

[0004] Therefore, those skilled in the art have provided an emergency shut-off device that integrates a rainwater well and a shut-off valve to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an emergency shut-off device that integrates a rainwater well and a shut-off valve. This device uses a first bidirectional motor to drive a drive bevel gear, causing the upper and lower discs to rotate simultaneously to achieve the emergency shut-off function. When one disc is damaged, the other can continue to work, ensuring the continuity of the emergency shut-off. At the same time, a second bidirectional motor drives the drive gear to adjust the position of the limit rod, precisely limiting the rotation range of the discs and preventing excessive hydraulic load from causing the discs to flip over, thus ensuring the reliability of the system under high water pressure conditions.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An emergency shut-off device integrating a rainwater well and a shut-off valve includes a rainwater well. A first bidirectional motor is disposed in the middle of one side of the rainwater well. Both ends of the first bidirectional motor are fixedly connected to first transmission rods. A driving bevel gear is sleeved on the outer side of each of the two first transmission rods. A driven bevel gear is meshed on one side of each of the two driving bevel gears. A rotating rod is sleeved inside each of the two driven bevel gears. A disc is fixedly connected to the outside of each of the two rotating rods. A second bidirectional motor is disposed in the middle of both sides of the rainwater well. Both ends of the two second bidirectional motors are fixedly connected to second transmission rods. A driving gear is sleeved on the outer side of multiple second transmission rods. A driven gear is meshed on one side of each of the multiple driving gears. A limiting rod is sleeved inside each of the multiple driven gears. A sieve plate is disposed at the upper end of the rainwater well. Vibration motors are disposed on both sides of the lower end of the sieve plate. A collection box is fixedly connected to the upper end of one side of the rainwater well.

[0008] Through the above technical solution, the device drives the active bevel gear with a first bidirectional motor to make the upper and lower discs rotate simultaneously to achieve the emergency cut-off function. When one disc is damaged, the other can continue to work to ensure the continuity of emergency cut-off. At the same time, the second bidirectional motor drives the active gear to adjust the position of the limit rod to precisely limit the rotation range of the discs, prevent excessive hydraulic load from causing the discs to flip, and ensure the reliability of the system under high water pressure conditions.

[0009] Furthermore, the upper end of the rainwater well is provided with a well cover, and the inside of the well cover is provided with water inlet grooves evenly spaced apart, and the upper end of the collection box is provided with a cover plate;

[0010] By using the above technical solution, water inlet channels can be evenly spaced on the manhole cover to effectively disperse and guide rainwater into the storm drain, which helps to improve rainwater drainage efficiency, prevent rainwater from accumulating or overflowing on the manhole cover, and thus reduce the risk of urban flooding.

[0011] Furthermore, two water passages are provided on one side of the rainwater well and one side of the collection box, and the multiple water passages are aligned with each other in pairs. The two lower water passages are equipped with filter screens inside.

[0012] The above technical solution involves creating a water passage trough on one side of the rainwater well and collection box, and installing a filter screen inside the lower water passage trough. This effectively filters out impurities and particulate matter in the rainwater, preventing these substances from entering the collection system and causing potential blockages.

[0013] Furthermore, both the upper ends of the rainwater well and the cover plate are provided with lifting holes;

[0014] The above technical solution allows operators to easily open or close the manhole cover and cover plate, facilitating daily inspection, maintenance, and rapid response in emergencies.

[0015] Furthermore, both ends of the two rotating rods extend into the interior of the rainwater well and are rotatably connected to it;

[0016] The above technical solution ensures the smoothness and accuracy of the disc when opening and closing by rotating the rod and connecting it to the inside of the rainwater well.

[0017] Furthermore, both discs are provided with sealing rings on their exterior surfaces;

[0018] The above technical solution enhances the sealing performance between the disc and the rainwater well, effectively preventing leakage of sewage or rainwater.

[0019] Furthermore, a battery and a controller are respectively installed at the upper and lower ends of one side of the rainwater well;

[0020] The above technical solutions enable automated control of rainwater wells, enhancing the system's intelligence. Especially in the event of a power outage, the battery ensures the system's normal operation, improving its reliability and emergency response capabilities, and ensuring continuous operation and timely response to various needs.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes an emergency shut-off device integrating a rainwater well and a shut-off valve. In use, the device uses a first bidirectional motor to drive a drive bevel gear, causing two discs at the upper and lower ends of the rainwater well to rotate simultaneously, thus achieving an emergency shut-off function. Even if one disc is damaged, the other disc can continue to perform the emergency shut-off, ensuring the continuity and effectiveness of emergency handling. Simultaneously, a second bidirectional motor drives the drive gear, causing the upper and lower limit rods to rotate and limit the discs, effectively restricting their rotation range and preventing them from rotating again due to excessive hydraulic load. This avoids backflow damage to the system, ensuring the system's reliability under high water pressure conditions.

[0023] 2. This utility model proposes an emergency shut-off device integrating a rainwater well and a shut-off valve. During use, a sieve plate is installed at the upper part of the rainwater well to effectively filter impurities in the rainwater, preventing them from entering the lower part and affecting the normal emergency shut-off function of the disc valve, thus ensuring the reliability of the emergency shut-off system. Furthermore, during the filtration process, a vibrating motor drives the sieve plate to vibrate, causing impurities to enter the collection box, thereby preventing impurities from accumulating on the sieve plate and ensuring smooth rainwater flow to the lower part. Simultaneously, workers can easily open the collection box to clean impurities, greatly improving cleaning efficiency and reducing manual cleaning workload. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-5 This utility model provides a specific embodiment: an emergency shut-off device integrating a rainwater well and a shut-off valve, comprising a rainwater well 1, a first bidirectional motor 2 disposed in the middle of one side of the rainwater well 1, a first transmission rod 3 fixedly connected to both ends of the first bidirectional motor 2, a driving bevel gear 4 sleeved on one side of each of the two first transmission rods 3, a driven bevel gear 5 meshing with one side of each of the two driving bevel gears 4, a rotating rod 6 sleeved inside each of the two driven bevel gears 5, and a disc 7 fixedly connected to the outside of each of the two rotating rods 6. The rainwater well 1 has a second bidirectional motor 9 installed in the middle of both sides inside. The two ends of the two second bidirectional motors 9 are fixedly connected to the second transmission rods 10. The outer side of the multiple second transmission rods 10 is fitted with a drive gear 11. The drive gears 11 are meshed with a driven gear 12 on one side. The driven gears 12 are fitted with a limit rod 13 inside. The upper end of the rainwater well 1 is fitted with a screen plate 14. The lower ends of the screen plate 14 are fitted with vibrating motors 15 on both sides. The upper end of one side of the rainwater well 1 is fixedly connected to a collection box 18.

[0033] The device uses a first bidirectional motor to drive an active bevel gear, which causes the upper and lower discs to rotate simultaneously to achieve an emergency cut-off function. When one disc is damaged, the other can continue to work, ensuring the continuity of the emergency cut-off. At the same time, the second bidirectional motor drives the active gear to adjust the position of the limit rod, precisely limiting the rotation range of the discs and preventing excessive hydraulic load from causing the discs to flip over, thus ensuring the reliability of the system under high water pressure conditions.

[0034] A manhole cover 16 is installed at the upper end of the rainwater well 1. Water inlet channels 17 are evenly spaced inside the manhole cover 16. A cover plate 19 is installed at the upper end of the collection box 18. By evenly spaced water inlet channels on the manhole cover, rainwater can be effectively dispersed and guided into the rainwater well, improving rainwater drainage efficiency and preventing rainwater from accumulating or overflowing on the manhole cover, thereby reducing the risk of urban flooding. Two water passage channels 21 are opened on one side of the rainwater well 1 and one side of the collection box 18, and these channels 21 are aligned with each other in pairs. Filter screens 24 are installed inside the two lower water passage channels 21. The water passage channels on one side of the rainwater well and collection box, and the filter screens inside the lower water passage channels, effectively filter out impurities and particulate matter in the rainwater, preventing these substances from entering the collection system and causing potential blockages. Pull-out mechanisms are installed on both sides of the upper end of the rainwater well 1 and the cover plate 19. The hole 20, with its lifting hole, allows operators to easily open or close the manhole cover and cover plate, facilitating daily inspection, maintenance, and rapid response in emergencies. Both ends of the two rotating rods 6 extend into the interior of the rainwater well 1 and are rotatably connected thereto. This rotatable connection ensures the smoothness and accuracy of the discs during opening and closing. Sealing rings 8 are installed on the exterior of both discs 7, enhancing the sealing performance between the discs and the rainwater well, effectively preventing leakage of sewage or rainwater. A battery 22 and a controller 23 are respectively installed at the upper and lower ends of one side of the rainwater well 1, enabling automated control of the rainwater well and improving the system's intelligence. Especially in the event of a power outage, the battery ensures the normal operation of the system, enhancing its reliability and emergency response capabilities, ensuring continuous operation and timely response to various needs.

[0035] Working Principle: During operation, the operator controls the first bidirectional motor via the controller, which drives the active bevel gear to rotate. This causes the two discs at the upper and lower ends of the rainwater well to rotate synchronously, maintaining a vertical position and completing the normal drainage operation. During drainage, the screen plate inside the rainwater well filters impurities from the rainwater, preventing them from entering the lower end and affecting the normal emergency shut-off function of the disc valve, thus ensuring the reliability of the emergency shut-off system. Simultaneously, the vibrating motor drives the screen plate to vibrate, causing impurities to enter the collection box, preventing them from accumulating on the screen plate and ensuring that rainwater flows smoothly to the lower end. The operator can easily open the collection box to clean impurities, greatly improving cleaning efficiency and reducing manual cleaning workload. In case of an emergency shut-off, the operator controls the first bidirectional motor via the controller to drive the active bevel gear to rotate, causing the two discs to rotate synchronously and complete the emergency shut-off function. At the same time, the second bidirectional motor drives the active gear to rotate, allowing the upper and lower limit rods to rotate and limit the discs, effectively restricting the rotation range of the discs and preventing them from rotating again due to excessive hydraulic load. This avoids water backflow damaging the system, thus ensuring the reliability of the system under high water pressure conditions.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
