Description

Technical Field

[0001] This invention relates to the field of urban drainage technology, specifically to an automatic urban drainage system with drainage assistance function. Background Technology

[0002] Urban drainage systems are engineering facilities systems that treat and discharge urban sewage and rainwater. They are a component of urban public facilities. Urban drainage systems typically consist of drainage pipes and sewage treatment plants. Under the system of separating sewage and rainwater, sewage is collected by drainage pipes, sent to sewage treatment plants, and then discharged into water bodies or recycled. Rainwater runoff is collected by drainage pipes and discharged into nearby water bodies.

[0003] The sewage under the drainage pipes comes from multiple sources, so the inside of the drainage pipes sometimes emits an odor. The existing drainage pipes cannot prevent the odor from spreading into the surrounding air through the water inlet, which is very unpleasant and affects people's normal breathing.

[0004] During the drainage process, impurities usually flow into the drainage pipe along with the sewage, which can easily affect the flow rate of the drainage pipe. Therefore, even if a water pump is used, it is still impossible to improve the problem of blockage caused by impurities, thus greatly reducing the actual use effect. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that sewage under drainage pipes comes from multiple sources, and therefore the drainage pipes sometimes emit odors. Existing drainage pipes cannot prevent the odors inside from being emitted into the surrounding air through the water inlet, which is very unpleasant and affects people's normal breathing. Therefore, this invention proposes an automatic urban drainage system with drainage assistance function.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0011] Furthermore, the second crushing component includes a rack, a rotating rod, a gear, a connecting ring, and crushing blades. The rotating rod is rotatably connected to the inside of the water guide tube via a bearing, and a gear is fixedly connected to the outer surface of the rotating rod near the middle. Several sets of connecting rings are fixedly connected to the outer surface of the rotating rod on both sides of the gear, and crushing blades are fixedly connected to the outer surface of the connecting rings. A rack is fixedly connected to the lower outer surface of the connecting rod, and the rack meshes with the gear.

[0012] Furthermore, the auxiliary components include a water level monitor, a motor, a fixed rod, a piston block, a spring, a movable cavity, a movable rod, a connecting plate, a guide roller, a traction rope, a winding ring, and a winding ring. The water level monitor is installed at the bottom of the inner surface of the water storage frame. Motors are installed on both sides of the inner surface of the water storage frame, and the output end of the motor is fixedly connected to a fixed rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, by setting up a water storage component, during the drainage process, sewage enters the interior of the water storage frame through the water inlet. The water storage frame is affected by the gravity of the water, which drives the limiting plate to pull the ring spring downward. At this time, the water outlet is separated from the block. Sewage enters the interior of the guide frame through the water outlet, and then enters the interior of the guide tube through the connecting tube and flows out through the water outlet pipe. When the amount of sewage in the sewage storage frame decreases to the point that the pressure on the water storage frame is less than the elastic force of the ring spring, the connection is made. Under the elastic force of the ring spring, the limiting plate pulls the water storage frame upward, so that the water outlet matches the block again. Therefore, during the process of very little drainage or no drainage, the odor of sewage below the water storage frame will not be emitted to the outside through the water outlet and affect the air environment.

[0017] 2. In this invention, by setting crushing component one and crushing component two to cooperate, when the water storage frame moves up and down, the connecting rod drives the rotating rod one to move up and down. Since the rotating rod one meshes with the rack one through the gear one at one end, the rotating rod one drives the connecting ring one and the crushing blade one on its surface to rotate when it moves up and down, thereby crushing the impurities in the sewage passing through the connecting cylinder, thus ensuring the water flow rate and reducing the probability of blockage inside.

[0018] As the connecting rod moves up and down, rack two moves up and down with it, thus driving gear two to rotate rotating rod two, which in turn drives the crushing blade two and connecting ring two on its surface to rotate, further crushing the impurities that enter the water guide cylinder. This works in conjunction with crushing component one to ensure the normal flow of sewage inside the drainage system. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figure 1-5 As shown, the present invention proposes an automatic urban drainage system with drainage assistance function, including a rainwater frame 1, a water guide tube 2, and a drain plate 3. The upper outer surface of the rainwater frame 1 is provided with a water inlet, and the drain plate 3 is provided inside the water inlet. The water guide tube 2 is fixedly connected to the lower outer surface of the rainwater frame 1 near the middle. The two outer surfaces of the water guide tube 2 are fixedly connected to the water outlet pipes 4. The inner surface of the rainwater frame 1 is fixedly connected to the middle. The lower outer surface of the water guide tube 5 is fixedly connected to the connecting tube 6, and the bottom end of the connecting tube 6 is fixedly connected to the rainwater frame 1. The inner surface of the connecting tube 6 is connected to the inner surface of the water guide tube 2.

[0029] The guide frame 5 is internally equipped with a water storage component 100, which includes a limiting plate 101, an annular spring 102, an annular groove 103, a water storage frame 104, a water outlet 105, a plug 106, and a support rod 107. An annular groove 103 is formed at the top of the inner surface of the rainwater frame 1, and an annular spring 102 is installed inside the annular groove 103. One end of the annular spring 102 is fixedly connected to the annular groove 103, and the other end is fixedly connected to the limiting plate 101. The limiting plate 101 has a trapezoidal cross-section. A water storage frame 104 is fixedly connected to the lower outer surface of the limiting plate 101. During drainage, sewage enters the interior of the water storage frame 104 through the inlet hole. The water storage frame 104 is affected by the gravity of the water, which causes the limiting plate 101 to pull the ring spring 102 downward. The water storage frame 104 protrudes upward in an arc shape near the middle. Several sets of water outlet holes 10 are evenly spaced in a ring on the inner surface of the water storage frame 104 near the bottom of the protrusion. 5. A block 106 is movably connected inside the outlet hole 105. The outlet hole 105 is disconnected from the block 106. Sewage enters the interior of the guide frame 5 through the outlet hole 105, and then enters the interior of the guide tube 2 through the connecting tube 6 and flows out through the outlet pipe 4. When the amount of sewage inside the sewage storage frame 104 decreases to the point that the pressure on the storage frame 104 is less than the elastic force of the ring spring 102, the limiting plate 101 pulls the storage frame 104 upward under the elastic force of the ring spring 102. The movement allows the outlet 105 to align with the block 106 again. A support rod 107 is fixedly connected to the lower outer surface of the block 106. Therefore, in the case of minimal drainage or no drainage, the odor of sewage below the water storage frame 104 will not be emitted to the outside through the outlet 105 and affect the air environment. The lower outer surface of the support rod 107 is fixedly connected to the rainwater frame 1. The crushing component 200 is located on the lower outer surface of the water storage frame 104 and extends into the interior of the connecting cylinder 6.

[0030] Example 2:

[0031] like Figure 1 and Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that a crushing component 200 is fixedly connected to the lower outer surface of the water storage component 100. The crushing component 200 includes a connecting rod 201, a rotating rod 202, a connecting ring 203, a crushing blade 204, and a rack 205. The connecting rod 201 is fixedly connected to the lower outer surface of the water storage frame 104 at a position corresponding to the connecting cylinder 6, and the bottom end of the connecting rod 201 penetrates into the interior of the connecting cylinder 6. The rotating rod 202 is rotatably connected to the outer surfaces of the connecting rod 201 at positions inside the connecting cylinder 6, and two sets of connecting rings 203 are fixedly connected at equal intervals to the outer surface of the rotating rod 202. When the water storage frame 104 moves up and down, the connecting rod 201 drives the rotating rod 202 to move up and down.

[0032] A crushing blade 204 is fixedly connected to the outer surface of the connecting ring 203. A gear 206 is fixedly connected to the end of the rotating rod 202 away from the connecting rod 201. A rack 205 is fixedly connected to both sides of the inner surface of the connecting cylinder 6 at positions corresponding to the gear 206. The rack 205 meshes with the gear 206. Therefore, when the rotating rod 202 moves up and down, it drives the connecting ring 203 and the crushing blade 204 on its surface to rotate, crushing impurities in the sewage passing through the connecting cylinder 6, thereby ensuring the water flow rate and reducing the probability of blockage inside. The bottom end of the connecting rod 201 penetrates into the interior of the water guide cylinder 2 and is connected to the crushing component 300.

[0033] Example 3:

[0034] like Figure 1 and Figure 4 As shown, the difference between this embodiment and Embodiments 1 and 2 is that a second crushing component 300 is provided below the first crushing component 200. The second crushing component 300 includes a second rack 301, a second rotating rod 302, a second gear 303, a second connecting ring 304, and a second crushing blade 305. The second rack 301 is fixedly connected to the lower outer surface of the connecting rod 201. During the up-and-down movement of the connecting rod 201, the second rack 301 moves up and down with it. The rotating rod 302 is rotatably connected to the inside of the water guide cylinder 2 through a bearing, and the outer surface of the rotating rod 302 is close to... A gear 2 303 is fixedly connected in the middle position. A rack 2 301 meshes with the gear 2 303. Several sets of connecting rings 2 304 are fixedly connected to the outer surface of the rotating rod 2 302 on both sides of the gear 2 303. Crushing blades 2 305 are fixedly connected to the outer surface of the connecting rings 2 304. The rotating rod 2 302 drives the crushing blades 2 305 and the connecting rings 2 304 on its surface to rotate, further crushing the impurities that enter the water guide cylinder 2. This works in conjunction with the crushing component 1 200 to ensure the normal flow of sewage inside the drainage system.

[0035] Example 4:

[0036] like Figure 1 , Figure 4 and Figure 5As shown, the difference between this embodiment and embodiments 1, 2, and 3 is that auxiliary components 400 are provided on the outer surfaces of both sides of the connecting cylinder 6 near the bottom. The auxiliary components 400 include a water level monitor 401, a motor 402, a fixed rod 403, a piston block 404, a spring 405, a movable cavity 406, a movable rod 407, a connecting plate 408, a guide roller 409, a traction rope 410, a winding ring 411, and a winding ring 412. A water level monitor 401 is provided at the bottom of the inner surface of the water storage frame 104, and motors 402 are provided on both sides of the inner surface of the water storage frame 104. The output end of the motor 402 is fixedly connected to the fixed rod 403. When the water level monitor 401 detects that the water level inside the drainage system exceeds the set value, the auxiliary components 400 are installed in the water level monitoring system. When the flow rate exceeds the preset range, it indicates that the drainage system is blocked to a certain extent, and the sewage discharge speed is slow. At this time, the motor 402 drives the fixed rod 403 to rotate in both directions. A winding ring 411 is fixedly connected to the outer surface of the fixed rod 403 near the motor 402, and a traction rope 410 is wound and connected to the outer surface of the winding ring 411. A guide roller 409 is rotatably connected inside the water storage frame 104 below the winding ring 411, and one end of the traction rope 410 passes through to the bottom of the guide roller 409 and is fixedly connected to the connecting plate 408. When the fixed rod 403 rotates in the forward direction, the winding ring 411 winds up the traction rope 410. When the fixed rod 403 rotates in the reverse direction, the winding ring 411 unwinds.

[0037] The two sides of the connecting cylinder 6 form a movable cavity 406 with the rainwater frame 1, and a piston block 404 is provided inside the movable cavity 406. A sealing ring 413 is provided on the outer surface of the piston block 404, and the outer surface of the sealing ring 413 is tightly fitted with the inner surface of the movable cavity 406. A movable rod 407 is fixedly connected to one side of the outer surface of the piston block 404 near the middle, and the movable rod 407 extends through to the outside of the movable cavity 406 and is fixedly connected to the connecting plate 408. A spring 405 is sleeved on the outer surface of the movable rod 407 at the position inside the movable cavity 406, and one end of the spring 405 is fixedly connected to the inner surface of the movable cavity 406, and the other end is fixedly connected to the piston block 404.

[0038] When the winding ring 411 is in a winding state, the traction rope 410 causes the piston block 404 to squeeze the spring 405 inside the movable cavity 406. At this time, the sewage and its internal impurities flow towards the movable cavity 406 under the attraction of the piston block 404. When the winding ring 412 is in an unwinding state, the piston block 404 moves in the direction of pulling the traction rope under the action of the spring 405, and pushes the sewage inside the movable cavity 406 into the connecting cylinder 6. Therefore, the movement of the piston block 404 can be used to make the water flow inside the connecting cylinder 6 and the water guide cylinder 2 flow repeatedly, perform preliminary dredging inside, and improve the sewage flow rate.

[0039] A winding ring 412 is fixedly connected to one end of the outer surface of the fixed rod 403, and a traction rope 414 is wound on the outer surface of the winding ring 412. One end of the traction rope 414 is fixedly connected to the winding ring 412, and the other end is fixedly connected to a push rod 415. The push rod 415 passes through the guide frame 5 and is fixedly connected to the water storage frame 104, and the push rod 415 is movably connected to the guide frame 5.

[0040] When the second traction rope 414 is in a coiled state, it pulls the push rod 415 to move the water storage frame 104 downward. When the second traction rope 414 is in an uncoiled state, the water storage frame 104, under the action of the ring spring 102, pulls the push rod 415 and the connecting rod 201 upward. During the repeated up and down movement of the connecting rod 201, the first crushing blade 204 and the second crushing blade 305 can further crush the impurities in the sewage, thereby cooperating with the piston block 404 to accelerate the sewage flow rate and unclog the inside of the drainage system.

[0041] The working process and principle of this invention are as follows:

[0042] During the drainage process, sewage enters the interior of the water storage frame 104 through the inlet hole. The water storage frame 104 is affected by the gravity of the water, which drives the limiting plate 101 to pull the ring spring 102 downward. At this time, the outlet hole 105 is separated from the block 106. Sewage enters the interior of the guide frame 5 through the outlet hole 105, and then enters the interior of the guide tube 2 through the connecting tube 6 and flows out through the outlet pipe 4. When the amount of sewage in the sewage storage frame 104 decreases to the point that the pressure on the storage frame 104 is less than the elastic force of the ring spring 102, the connection is established. Under the elastic force of the ring spring 102, the limiting plate 101 pulls the storage frame 104 upward, so that the outlet hole 105 matches the block 106 again. Therefore, during the process of very little drainage or no drainage, the odor of sewage below the storage frame 104 will not be emitted to the outside through the outlet hole 105 and affect the air environment.

[0043] When the water storage frame 104 moves up and down, the connecting rod 201 drives the rotating rod 202 to move up and down. Since the rotating rod 202 meshes with the rack 205 through the gear 206 at one end, the rotating rod 202 drives the connecting ring 203 and the crushing blade 204 on its surface to rotate when it moves up and down, thereby crushing the impurities in the sewage passing through the connecting cylinder 6, thus ensuring the water flow rate and reducing the probability of blockage inside.

[0044] During the up-and-down movement of the connecting rod 201, the rack 2 301 moves up and down with it, thus driving the drive gear 2 303 to drive the rotating rod 2 302 to rotate, causing the rotating rod 2 302 to drive the crushing blade 2 305 and the connecting ring 2 304 on its surface to rotate, further crushing the impurities that enter the water guide cylinder 2, thereby cooperating with the crushing component 1 200 to ensure the normal flow of sewage inside the drainage system;

[0045] When the water level monitor 401 detects that the drainage system exceeds the preset range, it indicates that the drainage system is blocked to a certain extent, and the sewage discharge speed is slow. At this time, the motor 402 drives the fixed rod 403 to rotate forward and backward. When the fixed rod 403 rotates forward, the first winding ring 411 and the second winding ring 412 wind up the first traction rope 410 and the second traction rope 414 respectively. Therefore, the first traction rope 410 is pulled, causing the piston block 404 to compress the first spring 405 inside the movable cavity 406. At this time, the sewage and its internal components are discharged slowly. Impurities in the part flow towards the movable cavity 406 under the attraction of the piston block 404. When the fixed rod 403 rotates in the opposite direction, the first winding ring 411 and the second winding ring 412 are unwound. The piston block 404 moves in the direction of pulling the traction rope under the action of the first spring 405, and pushes the sewage inside the movable cavity 406 into the connecting cylinder 6. Therefore, the movement of the piston block 404 can be used to make the water flow inside the connecting cylinder 6 and the water guide cylinder 2 flow repeatedly, perform preliminary dredging inside, and improve the sewage flow rate.

[0046] Furthermore, during the aforementioned process, when the second traction rope 414 is in a coiled state, it pulls the push rod 415 to move the water storage frame 104 downward. When the second traction rope 414 is in an uncoiled state, the water storage frame 104, under the action of the annular spring 102, pulls the push rod 415 and the connecting rod 201 upward. During the repeated up-and-down movement of the connecting rod 201, the first crushing blade 204 and the second crushing blade 305 can further crush the impurities in the sewage, thereby cooperating with the piston block 404 to accelerate the sewage flow rate and unclog the inside of the drainage system.
