Description

Technical Field

[0001] The present invention relates to the technical field of gates, and in particular to a buoyancy-adjusting sewage-intercepting and flood-discharging gate. Background Art

[0002] In the urban drainage system, the rainwater well is an important component. Its main function is to collect and discharge rainwater. The rainwater well is usually connected to a sewage pipe for treating pollutants in the initial rainwater. The gate is usually installed in the rainwater well, and its core structure includes a buoyancy component and a gate body. In the initial stage of rainfall, the water level in the rainwater well is relatively low, and the buoyancy received by the buoyancy component is not enough to drive the gate to open. At this time, the gate is in a closed state. Since there are many impurities in the initial rainwater and the water source is relatively turbid, the gate plays a role in intercepting sewage at this time, intercepting the pollutants in the initial rainwater in the rainwater well and discharging them through the connected sewage pipe to prevent them from entering the rainwater pipe network. As the rainfall increases, the water level in the rainwater well gradually rises. When the water level exceeds the set height of the buoyancy component, the buoyancy received by the buoyancy component increases, thereby driving the gate to open and gradually opening the flood-discharging channel to achieve rapid flood discharge. Since the gate is provided with buoyancy components such as floating barrels, it can automatically adjust the opening degree of the gate according to the change of the water level without manual intervention and has a good self-adjusting function;

[0003] In actual use, the sundries in the rainwater well are easily wound around the floating barrel. This winding phenomenon will interfere with the normal contact between the floating barrel and the water body, resulting in a reduction in the effective contact area between the floating barrel and the surrounding water body, and then changing the buoyancy received by the floating barrel, making it unable to accurately respond to the water level change, and ultimately having an adverse impact on the function of the floating barrel to drive the gate to open and hindering the timely opening of the gate.

[0004] To solve the above problems, a buoyancy-adjusting sewage-intercepting and flood-discharging gate is proposed in this application. Summary of the Invention

[0005] The present invention provides a buoyancy-adjusting sewage-intercepting and flood-discharging gate, which solves the problem in the related art that the sundries in the rainwater well are easily wound around the floating barrel, having an adverse impact on the floating barrel to drive the gate to open.

[0006] A buoyancy-adjusting sewage-intercepting and flood-discharging gate provided by the present invention includes a gate body, a gate plate, a floating barrel assembly and a driving member;

[0007] A flood-discharging port is opened on the gate body. The gate plate is rotatably installed on the gate body and seals the flood-discharging port. An inclined connecting rod is installed on the gate plate. A sliding port is opened in the connecting rod. The floating barrel assembly is slidably matched with the sliding port. An oil injection assembly is installed at one end of the connecting rod close to the gate plate. The driving member is used to drive the floating barrel assembly to slide in the sliding port and push the oil injection assembly to inject oil into the connection between the gate body and the gate plate;

[0008] The buoy assembly includes a buoy member and a scraping member. The scraping member abuts against the outer periphery of the buoy member. When the driving member drives the buoy assembly to slide in the sliding opening, the buoy member can be driven to rotate, and the scraping member scrapes the outer periphery of the buoy member.

[0009] As a further optimized solution of the present invention, the buoy assembly further includes a loading block, a gear and a gas supply member. The loading block is slidably matched with the sliding opening. The gas supply member is installed on the loading block. The buoy member is connected to the gas supply member.

[0012] As a further optimized solution of the present invention, the gas supply member includes a rotary joint. The rotary joint is installed on the other side of the loading block. The rotary outlet end of the rotary joint is connected to a gas supply pipe. The gas supply pipe rotatably passes through the loading block and is connected to an exhaust shaft located on one side of the loading block. A plurality of exhaust holes facing the buoy body are provided on the exhaust shaft. The gear is fixed on the gas supply pipe, and the assembly rod is fixed on the exhaust shaft. The inlet end of the rotary joint is connected to an inlet pipe, and the inlet pipe is connected to an air pump.

[0013] As a further optimized solution of the present invention, the oil injection assembly includes an oil injection cylinder. A hollow pipe is rotatably installed on the side surface of the gate body. The gate plate is fixedly sleeved on the hollow pipe. An assembly shaft is installed at one end of the connecting rod close to the gate plate, and the assembly shaft is fixedly sleeved on the hollow pipe. A first opening located between the gate body and the gate plate is provided on the hollow pipe. A second opening located between the connecting rod and the gate plate is also provided on the hollow pipe. The oil injection cylinder is installed on the inner wall of the connecting rod close to one end of the gate plate. One end of the oil injection cylinder is connected to an oil injection pipe communicated with the hollow pipe. An elastic oil pushing member is installed in the oil injection cylinder, and the elastic oil pushing member extends into the sliding opening.

[0014] As a further optimized solution of the present invention, the elastic oil-pushing member includes a piston, a push rod and a spring. The piston is slidably arranged in the oil injection cylinder. The piston divides the interior of the oil injection cylinder into an oil injection chamber and a gas-pushing chamber. Lubricating oil is arranged in the oil injection chamber. One end of the piston is provided with a push rod located in the gas-pushing chamber, and one end of the push rod slidably passes through the other end of the oil injection cylinder and extends into the sliding port. The spring is sleeved on the push rod, and the two ends of the spring are respectively connected to one end of the piston and the inner wall of the other end of the oil injection cylinder. The other end of the oil injection cylinder is provided with a third opening communicating with the gas-pushing chamber.

[0015] As a further optimized solution of the present invention, an oil supply assembly communicating with the oil injection chamber is installed on the oil injection cylinder, and the oil supply assembly is used to supplement oil into the oil injection chamber.

[0016] As a further optimized solution of the present invention, the oil supply assembly includes an oil supply pipe and an oil supply cylinder. The oil supply pipe is connected to the oil injection cylinder and communicates with the oil injection chamber. The oil supply cylinder is connected to the end of the oil supply pipe away from the oil injection cylinder. A one-way valve is installed on the oil supply pipe. An oil injection port is opened at the top of the oil supply cylinder, and a sealing plug is sealed in the oil injection port.

[0017] As a further optimized solution of the present invention, the driving member includes an electric slide rail. The electric slide rail is installed in the sliding port, and the loading block is installed at the driving end of the electric slide rail.

[0018] The above technical solution of the present invention has the following beneficial technical effects:

[0019] 1. By setting the floating cylinder assembly in the present invention, when the water level gradually rises, the floating cylinder assembly floats up with the rising of the water level. Since the floating cylinder assembly is arranged on the connecting rod, the gate plate can be driven to rotate on the gate body through the connecting rod. When the gate plate rotates, the flood discharge opening opened on the gate body can be gradually opened, and the water source can be discharged through the flood discharge opening. During the drainage process, after the sundries carried in the water adhere to the floating cylinder member, the floating cylinder assembly can be driven by the driving member to move in the sliding port opened in the connecting rod. When the floating cylinder assembly moves, it can drive the floating cylinder member to rotate. Under the centrifugal force, the sundries on its surface can be thrown out. This design can effectively clean the sundries on the surface of the floating cylinder member, avoid the reduction of the contact area between the floating cylinder member and the water body caused by the entanglement of the sundries, so as to ensure that the floating cylinder member can accurately sense the water level change, stably output buoyancy, ensure the normal operation of the function of driving the gate plate to open by the floating cylinder member, improve the reliability and response speed of the gate plate, and enable the rainwater well to perform flood discharge operations more efficiently during the drainage process;

[0020] 2. In the present invention, since a scraper that contacts the float member is provided on the float assembly, when the float member rotates, the scraper can further scrape away the debris on the surface of the float member, and combined with the way of throwing away the debris by centrifugal force, a double cleaning mechanism is formed. This deep cleaning method can make the debris on the surface of the float member clean more thoroughly, reduce the influence of the debris on the normal operation of the float member, and enhance the reliability and stability of the float member;

[0021] 3. The present invention can drive the float assembly to move in the sliding mouth through the driving member, so that the float assembly can be moved to the corresponding position on the connecting rod, thereby realizing flexible adjustment of the position of the float member. This function enables the float assembly to be adjusted according to actual working conditions and water level changes, so that the position of the float member can be adjusted as needed in different seasons or under different rainfall intensities, so as to adjust the opening and closing timing of the gate plate on the gate body, thereby improving the drainage efficiency and flexibility of the gate system, so that it can better adapt to the complex and changeable rainwater well drainage environment.

[0022] 4. The present invention provides an air supply component. When debris is attached to the float component, in order to further clean the debris, gas can be blown toward the float component through the air supply component. When blowing air, bubbles can be generated in the water. These bubbles form an impact force on the surface of the float component to further loosen and remove the attached debris. Combined with the centrifugal force throwing out and the scraping component scraping away the debris, this air blowing cleaning method forms a multi-dimensional debris cleaning mechanism, which can more thoroughly clean the debris on the surface of the float component.

[0023] 5. During the long-term use of the gate body of the present invention, the gate plate needs to be rotated frequently, and the connection between the gate plate and the gate body is easy to wear. The driving member can drive the float assembly to move to the end of the connecting rod close to the gate plate, and pressure can be applied to the oil injection assembly at the end of the connecting rod close to the gate plate, so that the oil in the oil injection assembly is injected between the gate body and the gate plate, which plays a lubricating role and reduces the friction when the gate plate rotates on the gate body. This lubrication mechanism can effectively reduce the wear between components, extend the service life of the gate plate and the gate body, reduce the maintenance cost and replacement frequency of the equipment, and improve the operating efficiency and reliability of the gate system;

[0024] 6. With the oil supply component provided in the present invention, when the driving member drives the floating barrel component to move in the sliding opening to approach one end of the gate plate, pressure can be exerted on the elastic oil pushing member, and the oil in the oil injection cylinder is injected into the hollow pipe through the oil injection pipe. Then, the oil is discharged between the gate body and the gate plate through the first opening provided on the hollow pipe. When the driving member drives the floating barrel component to return to its original position, the elastic oil pushing member can return to its original position, generating a suction in the oil injection cylinder, sucking the lubricating oil in the oil supply component into the oil injection cylinder for the next oil injection preparation. This automatic oil supply and lubrication mechanism ensures that there is always sufficient lubricating oil in the oil injection component, provides continuous guarantee for the lubrication between the gate plate and the gate body, and further optimizes the lubrication mechanism of the gate system.

[0025] 7. The present invention organically combines the debris cleaning and oil injection processes through the movement of the floating barrel component, forming a synergistic mechanism. While cleaning debris, the friction between the gate body and the gate plate is reduced by injecting oil for lubrication. This design not only effectively avoids the damage to the function of the floating barrel component caused by debris accumulation, ensures that the floating barrel component can accurately sense the water level change and stably output buoyancy, thus guaranteeing the normal opening and closing of the gate plate, but also reduces the wear generated at the connection between the gate body and the gate plate due to frequent rotation, extends the service life of the gate system. At the same time, it reduces the risk of equipment failure caused by component wear and debris accumulation, reduces the equipment maintenance cost and replacement frequency, improves the operation efficiency and reliability of the gate system, enables it to better adapt to the complex and changeable rainwater well drainage environment, and provides a strong guarantee for the efficient flood discharge operation of the rainwater well.

Detailed implementation manners

[0038] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0039] As Figures 1-11 shown, a buoyancy-adjustable sewage interception and flood discharge gate proposed by the present invention includes a gate body 1, a gate plate 102, a floating cylinder assembly 3 and a driving member;

[0040] A flood discharge opening 101 is formed in the gate body 1, the gate plate 102 is rotatably installed on the gate body 1 and closes the flood discharge opening 101, an inclined connecting rod 2 is installed on the gate plate 102, a sliding opening 21 is formed in the connecting rod 2, the floating cylinder assembly 3 is slidably engaged with the sliding opening 21, an oil injection component 4 is installed at one end of the connecting rod 2 close to the gate plate 102, and the driving member is used to drive the floating cylinder assembly 3 to slide in the sliding opening 21 and push the oil injection component 4 to inject oil into the connection between the gate body 1 and the gate plate 102;

[0041] The buoy assembly 3 includes a buoy member 31 and a scraping member 32. The scraping member 32 abuts against the outer periphery of the buoy member 31. When the driving member drives the buoy assembly 3 to slide in the sliding opening 21, the buoy member 31 can be driven to rotate, and the scraping member 32 scrapes the outer periphery of the buoy member 31.

[0042] When the water level rises in the present invention, the buoy assembly 3 is driven by the buoyancy force to drive the connecting rod 2 to rotate around the connection point with the gate plate 102, and then the gate plate 102 rotates around the installation point. (The initial position of the buoy assembly 3 is as Figure 1 shown), gradually opening the flood discharge opening 101 for flood discharge. The driving member is started to drive the buoy assembly 3 to slide in the sliding opening 21. The sliding of the buoy assembly 3 drives the buoy member 31 to rotate, and the sundries on the surface of the buoy member 31 are thrown out by the centrifugal force. At the same time, the scraping member 32 scrapes the outer periphery of the buoy member 31 to further clean the sundries. In addition, the sliding of the buoy assembly 3 pushes the oil injection assembly 4, so that the oil injection assembly 4 injects the oil liquid to the connection between the gate body 1 and the gate plate 102, playing a lubricating role and reducing wear.

[0043] As Figure 2 、 Figure 4 and Figure 5 shown, in this embodiment, the buoy assembly 3 further includes a loading block 33, a gear 34 and a gas supply member 35. The loading block 33 is slidably matched with the sliding opening 21. The gas supply member 35 is installed on the loading block 33. The buoy member 31 is connected to the gas supply member 35. A rack 23 is installed on the back surface of the connecting rod 2. The gear 34 is fixed on the gas supply member 35 and meshes with the rack 23. When the driving member drives the loading block 33 to slide in the sliding opening 21, the gear 34 rolls on the rack 23, and drives the buoy member 31 to rotate through the gas supply member 35.

[0044] In the present invention, the driving member drives the loading block 33 to slide in the sliding opening 21. The loading block 33 drives the gas supply member 35 to move, so that the gear 34 fixed on the gas supply member 35 rolls on the rack 23, and then drives the buoy member 31 to rotate through the gas supply member 35. Compared with simply relying on the driving member to push the buoy assembly 3 to slide to make the buoy member 31 rotate, this way of meshing the gear 34 with the rack 23 can make the buoy member 31 rotate more stably and efficiently, enhance the sundries cleaning effect, and ensure the stability of the buoy member 31 during operation.

[0045] As Figure 6 shown, in this embodiment, the buoy member 31 includes a buoy body 311 and an assembly rod 312. The assembly rod 312 is connected to the gas supply member 35. The buoy body 311 is installed at one end of the assembly rod 312.

[0046] The air supply member 35 of the present invention drives the assembly rod 312 to rotate, thereby causing the floating cylinder body 311 installed at one end of the assembly rod 312 to rotate. The floating cylinder body 311 is the main component for generating buoyancy of the floating cylinder assembly 3. Its structural design can ensure stable buoyancy generation during rotation, and at the same time, it is convenient for surface debris to be cleaned during rotation, ensuring the normal functioning of the floating cylinder assembly 3.

[0047] As Figure 6 shown in Figure 7 In this embodiment, the scraping member 32 includes a loading rack 321 and a scraping blade 322. The loading rack 321 is installed on one side of the loading block 33 and is placed on the outer periphery of the floating cylinder body 311. The scraping blade 322 is installed on the loading rack 321 and abuts against the outer periphery of the floating cylinder body 311.

[0048] In the present invention, when the floating cylinder body 311 rotates, the scraping blade 322 installed on the loading rack 321 abuts against the outer periphery of the floating cylinder body 311. The scraping blade 322 scrapes off the debris attached to the surface of the floating cylinder body 311. The setting of the scraping member 32 cooperates with the centrifugal force of the floating cylinder body 311 to clean the debris, forming a double cleaning mechanism, which can further clean the debris on the surface of the floating cylinder body 311 and reduce the influence of the debris on the floating cylinder assembly 3.

[0049] As Figure 7 shown in Figure 8 In this embodiment, the air supply member 35 includes a rotary joint 351. The rotary joint 351 is installed on the other side of the loading block 33. The rotary air outlet end of the rotary joint 351 is connected to an air supply pipe 352. The air supply pipe 352 rotates through the loading block 33 and is connected to an exhaust shaft 353 located on one side of the loading block 33. A plurality of exhaust holes 354 facing the floating cylinder body 311 are provided on the exhaust shaft 353. The gear 34 is fixed on the air supply pipe 352, and the assembly rod 312 is fixed on the exhaust shaft 353. The intake end of the rotary joint 351 is connected to an intake pipe 355, and the intake pipe 355 is connected to an air pump; in actual use, the air pump is installed outside the rainwater well, and in order to save costs, a shunt pipe can be connected to the air pump according to actual use requirements, and the shunt pipe is used to supply air to multiple intake pipes 355.

[0050] After the air pump is started, the gas generated by the air pump is delivered to the intake end of the rotary joint 351 through the intake pipe 355. The rotary joint 351 enables its rotary outlet end to stably transmit the gas to the supply pipe 352 while rotating, and its intake end remains connected to the intake pipe 355. After receiving the gas, the supply pipe 352 guides the gas to the exhaust shaft 353. Since a number of exhaust holes 354 are provided on the exhaust shaft 353 and are arranged towards the floating cylinder body 311, the gas will be ejected from these exhaust holes 354 at high speed to form an air flow blowing towards the surface of the floating cylinder body 311. At the same time, when the driving member drives the loading block 33 to slide in the sliding port 21, the gear 34 fixed on the supply pipe 352 will roll on the rack 23. The rolling of the gear 34 drives the supply pipe 352 to rotate, and then the exhaust shaft 353 connected to the supply pipe 352 and the assembly rod 312 and the floating cylinder body 311 fixed on the exhaust shaft 353 rotate together. During the rotation of the floating cylinder body 311, the air flow ejected from the exhaust holes 354 can blow the surface of the floating cylinder body 311 in all directions, and the impact force of the air flow is used to loosen and blow off the sundries attached to the surface of the floating cylinder body 311.

[0051] As Figure 4 , Figure 5 , Figure 9 and Figure 10 shown, in this embodiment, the oil injection assembly 4 includes an oil injection cylinder 41. A hollow pipe 103 is rotatably installed on the side of the gate body 1. The gate plate 102 is fixedly sleeved on the hollow pipe 103. One end of the connecting rod 2 close to the gate plate 102 is provided with an assembly shaft 24, and the assembly shaft 24 is fixedly sleeved on the hollow pipe 103. A first opening 104 is provided on the hollow pipe 103 between the gate body 1 and the gate plate 102. A second opening 105 is also provided on the hollow pipe 103 between the connecting rod 2 and the gate plate 102. The oil injection cylinder 41 is installed on the inner wall of one end of the connecting rod 2 close to the gate plate 102. One end of the oil injection cylinder 41 is connected with an oil injection pipe 43 communicating with the hollow pipe 103. An elastic oil pushing member 42 is installed in the oil injection cylinder 41, and the elastic oil pushing member 42 extends into the sliding port 21.

[0052] When the driving member drives the floating cylinder assembly 3 to move to one end of the connecting rod 2 close to the gate plate 102, the floating cylinder assembly 3 pushes the elastic oil pushing member 42, so that the oil in the oil injection cylinder 41 enters the hollow pipe 103 through the oil injection pipe 43, and then flows to the connection between the gate body 1 and the gate plate 102 through the first opening 104 on the hollow pipe 103, playing a lubricating role. The design of this oil injection assembly 4 can automatically lubricate the gate connection, reduce wear, and extend the service life of the gate.

[0053] It should be noted that: In the present invention, the movement of the buoy assembly 3 organically combines the debris cleaning and oil injection processes, forming a synergistic mechanism. While cleaning debris, the friction between the gate body 1 and the gate plate 102 is reduced by injecting oil for lubrication. This design not only effectively avoids the damage of the buoy assembly 3 function caused by debris accumulation, ensures that the buoy assembly 3 can accurately sense the water level change and stably output buoyancy, thereby ensuring the normal opening and closing of the gate plate 102, but also reduces the wear generated at the connection between the gate body 1 and the gate plate 102 due to frequent rotation, extends the service life of the gate system. At the same time, it reduces the risk of equipment failure caused by component wear and debris accumulation, reduces the equipment maintenance cost and replacement frequency, improves the operation efficiency and reliability of the gate system, enables it to better adapt to the complex and changeable rainwater well drainage environment, and provides a strong guarantee for the efficient flood discharge operation of the rainwater well.

[0054] As Figure 11 shown, in this embodiment, the elastic oil-pushing member 42 includes a piston 421, a push rod 422 and a spring 423. The piston 421 is slidably arranged in the oil injection cylinder 41. The piston 421 divides the interior of the oil injection cylinder 41 into an oil injection chamber and a gas-pushing chamber. Lubricating oil is arranged in the oil injection chamber. One end of the piston 421 is provided with a push rod 422 located in the gas-pushing chamber, and one end of the push rod 422 slidably passes through the other end of the oil injection cylinder 41 and extends into the sliding port 21. The spring 423 is sleeved on the push rod 422, and both ends of the spring 423 are respectively connected to one end of the piston 421 and the inner wall of the other end of the oil injection cylinder 41. The other end of the oil injection cylinder 41 is provided with a third opening 424 communicating with the gas-pushing chamber.

[0055] The buoy assembly 3 pushes the push rod 422, causing the piston 421 to slide in the oil injection cylinder 41, compressing the lubricating oil in the oil injection chamber, and discharging it through the oil injection pipe 43 for oil injection. When the buoy assembly 3 returns to its original position, the spring 423 pushes the piston 421 to reset, generating negative pressure in the gas-pushing chamber, inhaling air through the third opening 424, and at the same time generating suction in the oil injection chamber, sucking in lubricating oil from the oil supply assembly 5. The structural design of the elastic oil-pushing member 42 realizes the automatic cycle of oil injection and oil suction, ensuring the continuous operation of the oil injection assembly 4.

[0056] As Figure 10 With Figure 11 shown, in this embodiment, an oil supply assembly 5 communicating with the oil injection chamber is installed on the oil injection cylinder 41, and the oil supply assembly 5 is used to supplement oil to the oil injection chamber.

[0057] When the lubricating oil in the oil filling cylinder 41 decreases, the one-way valve 53 prevents the lubricating oil in the oil filling chamber from flowing back. Under the suction effect generated by the oil filling cylinder 41, the lubricating oil in the oil supply cylinder 52 enters the oil filling chamber through the oil supply pipe 51 to supplement the lubricating oil. The setting of the oil supply assembly 5 ensures that there is always enough lubricating oil in the oil filling assembly 4, providing continuous guarantee for the lubrication of the gate.

[0058] As Figure 10 In Figure 11 the present embodiment shown, the oil supply assembly 5 includes an oil supply pipe 51 and an oil supply cylinder 52. The oil supply pipe 51 is connected to the oil filling cylinder 41 and communicates with the oil filling chamber. The oil supply cylinder 52 is connected to one end of the oil supply pipe 51 away from the oil filling cylinder 41. A one-way valve 53 is installed on the oil supply pipe 51. An oil filling port is provided at the top of the oil supply cylinder 52, and a sealing plug 54 is sealed in the oil filling port.

[0059] The one-way valve 53 only allows the lubricating oil to flow from the oil supply cylinder 52 to the oil filling cylinder 41, preventing the lubricating oil from flowing back. When filling the lubricating oil into the oil supply cylinder 52, the sealing plug 54 is opened to inject the lubricating oil, and then the sealing plug 54 seals the oil filling port to prevent the lubricating oil from leaking. This design ensures the normal operation of the oil supply assembly 5 and the effective supply of the lubricating oil.

[0060] As Figure 4 shown, in the present embodiment, the driving member includes an electric slide rail 22. The electric slide rail 22 is installed in the slide opening 21, and the loading block 33 is installed at the driving end of the electric slide rail 22. When the electric slide rail 22 is powered on and started, its driving end drives the loading block 33 to slide in the slide opening 21, thereby driving the overall movement of the floating drum assembly 3. As the driving member, the electric slide rail 22 can control the movement of the floating drum assembly 3 to flexibly adjust the position of the floating drum member 31, meeting the requirements of different working conditions and water level changes.

[0061] The specific working principle of the present invention is as follows:

[0062] In the initial stage of rainfall, the water level in the rainwater well is relatively low, and the buoyancy received by the floating drum assembly 3 is not enough to drive the gate to open. The gate plate 102 blocks the flood discharge port 101, and the sewage interception function is started. The pollutants in the initial rainwater are intercepted in the rainwater well and discharged through the sewage pipe. As the rainfall increases and the water level rises, the floating drum assembly 3 floats in the slide opening 21 under the action of buoyancy, driving the connecting rod 2 to rotate, and then causing the gate plate 102 to rotate around the installation point, gradually opening the flood discharge port 101 for flood discharge;

[0063] During the drainage process, if debris adheres to the surface of the buoy member 31, the electric slide rail 22 is activated to drive the loading block 33 to slide within the sliding opening 21, causing the gear 34 to roll on the rack 23, driving the air supply member 35 and the buoy member 31 to rotate, using centrifugal force to throw out the debris. At the same time, the scraping piece 322 of the scraping member 32 scrapes and cleans the outer periphery of the buoy member 31. The air supply member 35 blows air to the buoy member 31 through the air inlet pipe 355, the rotary joint 351, the air supply pipe 352, and the exhaust holes 354 on the exhaust shaft 353 to further loosen and remove the debris;

[0064] When lubrication is required at the connection between the gate body 1 and the gate plate 102, the electric slide rail 22 drives the buoy assembly 3 to move to one end of the connecting rod 2 close to the gate plate 102, pushing the elastic oil pushing member 42, so that the oil in the oil injection cylinder 41 enters the hollow pipe 103 through the oil injection pipe 43, and then flows to the connection for lubrication through the first opening 104. After that, the electric slide rail 22 drives the buoy assembly 3 to return to its original position, the elastic oil pushing member 42 resets, and the oil injection cylinder 41 sucks lubricating oil from the oil supply assembly 5 to prepare for the next oil injection. Through the coordinated work of each component, the flood discharge gate realizes functions such as sewage interception, flood discharge, buoy cleaning, and automatic lubrication, improving the drainage efficiency and reliability and adapting to the complex and changeable drainage environment of the rainwater well.

[0065] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples that fall within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
