[0002] If we pay attention to developing rainwater collection and utilization projects in urban construction, and keep the rainwater that was originally drained for use, it will not only increase water resources, but also be a good measure to save tap water. At the same time, through the extensive development of rainwater collection and utilization, since rainwater is retained or infiltrated back into the ground, the drainage volume is reduced, and the threat of urban flood disasters is reduced. Therefore, groundwater can be replenished, the water environment can be improved, and the ecological environment can be restored. It can be said that rainwater collection and utilization is one of the important measures for the sustainable utilization of urban water resources.

[0003] Since rainwater contains a large amount of debris, it needs to be intercepted and purified before it actually flows into the sewage treatment pipeline in order to significantly reduce the debris content in the rainwater. However, continuous interception and purification work will make general filtering equipment prone to blockage problems, so a kind of sewage interception and purification equipment that can perform continuous filtering work is needed to cope with high-load water purification work.

Flexible soft shells are symmetrically arranged on the left and right sides of the top of the inner wall of the vertical tube. The flexible soft shell can be easily deformed due to the action of external force, thereby driving the spring push rod to move.

[0010] Furthermore, one end of the spring push rod away from the flexible soft shell is squeezed against the outer surface of the one-way rotating plate through a rubber end head, and the other end of the spring push rod away from the rubber end head is squeezed against the inner wall of the flexible soft shell, and the outer surface of the spring push rod is fixedly connected to the outer surface of the guide sleeve away from the flexible soft shell through a compression spring.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can perform simple filtering and impurity removal on rainwater through the filtering equipment on both sides to ensure that the rainwater does not contain large waste before purification. In order to ensure that the filter belt does not lose its filtering effect due to mesh blockage during continuous rainwater filtering, the inclination angle of the filter belt is changed by pulling the sliding outer frame, and the impurities on the surface of the filter belt are removed by the flushing effect of rainwater. Under the premise of not replacing the filter belt, it is ensured that the device can continuously purify rainwater and separate rainwater and debris at the same time.

[0014] 2. When the drainage sub-shell slides upward relative to the filter belt, the impact rod will lift the lower surface of the filter belt upward, causing the filter belt to deform, and the objects accumulated on the upper surface of the filter belt will be pushed away by the protruding parts and then broken up, so that the rain can more easily disperse these objects. In order to prevent the impact rod from breaking the filter belt, the elastic pressure cylinder will be compressed when the impact rod encounters strong resistance, thereby alleviating the thrust on the filter belt. The mesh of the filter belt will expand due to the stretching effect of the extension belt and the thrust of the impact rod. At this time, impurities stuck in the mesh of the filter belt will be more easily washed away.

[0015] 3. The device opens the one-way rotating plates on both sides pneumatically, so that more debris can be drained into the solid recovery equipment. Since the vertical tube controlling the one-way rotating plate is always in a sealed state and the internal pressure is monitored by the pressure-sensitive inner tube to prevent the flexible soft shell from losing thrust due to air leakage, the overall stability of the device is relatively high, and there is no electrical mechanical equipment in direct contact with rainwater.

[0016] 4. The inside of the axis bar shell of the device is constantly collecting larger waste materials, so there may be internal blockage problems. At this time, the vertical tube is rotated by the torque chassis, and the thrust of the rubber end is utilized to connect the sliding outer frame and the drainage chamber together under the action of strong friction, so that the sliding outer frame and the drainage chamber move synchronously. The objects inside the drainage chamber impact downward under the action of inertia and gravity, thereby clearing the inner cavity of the axis bar shell, promoting the rapid discharge of internal debris, and thus solving the problem of internal blockage.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 4 The present invention provides a technical solution: an urban rainwater interception and purification device, comprising an adjustment device 1, a solid recovery device 2 is arranged at the axis of the adjustment device 1, and filtering devices 3 are symmetrically arranged on both sides of the inner wall of the adjustment device 1;

[0027] The adjustment device 1 comprises a fixed top frame 11, a limited baffle 12 is fixedly connected to the axis center of the top of the fixed top frame 11, a pressure-sensitive connecting tube 13 is fixedly connected to the lower surface of the limited baffle 12, a sliding outer frame 14 is slidably connected to the lower part of the inner wall of the fixed top frame 11, the front and rear sides of the top of the sliding outer frame 14 are fixedly connected to the outer surface of the fixed top frame 11 through a waterproof sealing tape 16, and external traction cylinders 18 are evenly arranged on the front and rear sides of the lower surface of the fixed top frame 11, and the bottom end of the output shaft of the external traction cylinder 18 is fixedly connected to an external pull plate 17, and the side of the external pull plate 17 is fixedly connected to the outer surface of the sliding outer frame 14. Under the action of gravity, rainwater is drained into the interior of the sliding outer frame 14 through the fixed top frame 11, and then diverted to the filtering devices 3 on both sides;

[0028] The filtering device 3 includes a drainage sub-shell 31, and a fixed guide plate 32 is fixedly connected to the middle part of the inner wall of the drainage sub-shell 31. The fixed guide plate 32 will not completely block the inner wall of the drainage sub-shell 31. The filtered rainwater is discharged downward through the hydrophobic mesh plate 38. An impact rod 33 is slidably connected to the axis of the inner wall of the fixed guide plate 32, and an elastic pressure cylinder 37 is fixedly connected to the bottom end of the impact rod 33. The bottom end of the elastic pressure cylinder 37 is fixedly connected to the hydrophobic mesh plate 38. The top end of the impact rod 33 is rotatably connected to a filter mesh belt 34, and the top end of the filter mesh belt 34 is fixedly connected to an extension belt 35. The bottom end of the filter mesh belt 34 is rotatably connected to a side fixed plate 36 through a guide shaft. The side fixed plate 36 is fixed on the solid recovery device 2 and slides relative to the drainage sub-shell 31.

[0029] There are two extension belts 35, and the inner cavity of the filter belt 34 is evenly provided with water-permeable openings. The outer surface of the extension belt 35 is slidably connected to the upper part of the inner wall of the sliding outer frame 14, and the top of the extension belt 35 extends to the bottom of the inner cavity of the fixed top frame 11. The outer surface of the extension belt 35 is slidably connected to the inner cavity of the fixed top frame 11 through a connecting spring. Two spring belts are provided at the part where the extension belt 35 extends to the cavity shell on both sides of the fixed top frame 11, so that the extension belt 35 can slide along the cavity shell of the fixed top frame 11 and prevent the extension belt 35 from completely sliding out of the cavity shell. The outer surface of the drainage sub-shell 31 is fixedly connected to the inner wall of the sliding outer frame 14, and the bottom of the drainage sub-shell 31 extends to the outside of the sliding outer frame 14. The front and rear sides of the outer surface of the filter belt 34 are both slidably connected to the inner wall of the sliding outer frame 14, and the side of the fixed top frame 11 is fixedly connected to the inner wall of the hole.

[0030] The device is first installed underground, with its fixed top frame 11 fixed to the inner wall of the hole, and then the pipes for inputting rainwater are connected to the ends of the drainage sub-shells 31 on both sides of the bottom to complete the installation of the device.

[0031] The rainwater is drained into the filter devices 3 on both sides through the fixed top frame 11 at the top. At this time, the rainwater is mixed with more solid matter, so the rainwater will flow into the interior of the drainage sub-shell 31 through the filter mesh belt 34, and after passing through the hydrophobic mesh plate 38, it will be recovered to the water purification device from the pipe below, while the solid matter will remain on the upper surface of the filter mesh belt 34. During continuous filtering, the upper surface of the filter mesh belt 34 will affect its rainwater filtering effect due to too many residual objects. At this time, the external traction cylinder 18 on the front and rear sides of the lower surface of the fixed top frame 11 will pull the external pull plate 17 upward, the waterproof sealing belt 16 is compressed, and the sliding outer frame 14 drives the filter devices 3 on both sides of the inner wall to slide upward, but the end portion of the extension belt 35 is connected to the inner cavity of the fixed top frame 11, so when the sliding outer frame 14 slides up, the extension belt 35 will be pushed upward by the thrust at the top, and at this time the extension belt 35 slides out of the inner cavity of the fixed top frame 11, thereby pulling the filter mesh belt 34 to gradually become more inclined.

[0032] When the drainage sub-shell 31 slides upward relative to the filter mesh belt 34, the impact rod 33 will push the lower surface of the filter mesh belt 34 upward to deform the filter mesh belt 34, and the objects accumulated on the upper surface of the filter mesh belt 34 will be pushed away by the protruding part and then broken up, so that rainwater can more easily disperse these objects. In order to prevent the impact rod 33 from breaking the filter mesh belt 34, the elastic pressure cylinder 37 will be compressed when the impact rod 33 encounters strong resistance, thereby alleviating the thrust on the filter mesh belt 34.

[0033] When rainwater enters the filter device 3 again through the fixed top frame 11, it will flush the inclined filter belt 34, and flush the objects on the upper surface of the filter belt 34 into the solid recovery device 2 in the middle, thereby cleaning the filter belt 34. In addition, the mesh of the filter belt 34 will be enlarged due to the drawing effect of the extension belt 35, and the impurities stuck in the mesh of the filter belt 34 will be more easily washed away.

[0034] After flushing for a certain period of time, the external traction cylinder 18 pushes the external pull plate 17 to push the sliding outer frame 14 down and back into place. The extension belt 35 also shrinks back into the inner cavity of the fixed top frame 11 under the thrust of the top compression spring. At this time, the filter belt 34 in a generally inclined state has a better filtering effect and continues to filter rainwater.

[0035] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of embodiment 1, the solid recovery equipment 2 includes a drainage chamber 21, and one-way rotating plates 22 are symmetrically arranged on both sides of the inner wall of the drainage chamber 21. The one-way rotating plates 22 can only rotate toward the outside of the drainage chamber 21. A vertical tube 23 is rotatably connected to the axis of the inner wall of the drainage chamber 21. A pressure-sensitive inner tube 24 is fixedly connected to the top of the inner cavity of the vertical tube 23. A pressurizing tube 25 is fixedly connected to the bottom of the inner wall of the vertical tube 23. An air delivery pipe 26 is fixedly connected to the axis of the bottom of the inner cavity of the pressurizing tube 25. A torque chassis 27 is fixedly connected to the bottom of the inner wall of the drainage chamber 21. The pressurizing tube 25 can compress external air into the interior of the vertical tube 23 through the air delivery pipe 26, and then monitor the internal pressure of the vertical tube 23 through the pressure-sensitive inner tube 24 at the top. The torque chassis 27 can deflect the vertical tube 23 by twisting the bottom end of the vertical tube 23.

[0036] The left and right sides of the upper part of the inner cavity of the vertical tube 23 are fixedly connected with a guide sleeve 28 through an insertion interface, a spring push rod 29 is slidably connected to the axis of the inner wall of the guide sleeve 28, and a rubber end 210 is fixedly connected to the end of the spring push rod 29 close to the one-way rotating plate 22. Flexible soft shells 211 are symmetrically arranged on the left and right sides of the top of the inner wall of the vertical tube 23. The flexible soft shell 211 can be easily deformed due to the action of external forces, thereby driving the spring push rod 29 to move.

[0037] One end of the spring push rod 29 away from the flexible soft shell 211 is squeezed against the outer surface of the one-way rotating plate 22 through the rubber end 210, and the other end of the spring push rod 29 away from the rubber end 210 is squeezed against the inner wall of the flexible soft shell 211. The outer surface of the spring push rod 29 is fixedly connected to the outer surface of the guide sleeve 28 away from the flexible soft shell 211 through a compression spring.

[0038] The drainage chamber 21 includes an axis bar shell 2101, and guide chutes 2102 are symmetrically provided on the front and rear sides of the outer surface of the axis bar shell 2101, and a water sealing plate 2103 is fixedly connected to the top of the inner cavity of the axis bar shell 2101. Veneer slides 2104 are symmetrically provided on the front and rear sides of the top of the inner wall of the axis bar shell 2101, and the inner cavity of the veneer slides 2104 is evenly provided with sliding rods 2105. There are two veneer slides 2104, and the side of the outer surface of the veneer slide 2104 away from the vertical tube 23 is fixedly connected to the inner wall of the axis bar shell 2101 through a spring belt, and the inner cavity of the guide chute 2102 is evenly provided with through sockets, and the end of the sliding rod 2105 away from the veneer slide 2104 is plugged into the inner cavity of the guide chute 2102 through the through socket. The top end of the vertical tube 23 is rotatably connected to the axis of the inner wall of the water sealing plate 2103, and vertical slide bars 15 are evenly arranged on the front and rear sides of the middle of the inner wall of the sliding outer frame 14. The outer surface of the vertical slide bar 15 is slidably connected to the outer surface of the axis bar shell 2101 through the guide groove 2102, and the end of the sliding rod 2105 away from the veneer slide plate 2104 is pressed against the outer surface of the vertical slide bar 15.

[0039] When the external traction cylinder 18 is working, the pressure cylinder 25 will draw air from the outside through the air supply pipe 26 to pressurize the inside of the vertical tube 23. Then the flexible soft shell 211 starts to push the spring push rod 29 on the corresponding side to slide toward the side close to the one-way turn plate 22 due to the increased pressure, and pushes the one-way turn plate 22 outward through the rubber end head 210. At this time, the objects washed by rainwater will be drained along the inclined surface of the filter belt 34 to the inside of the axis strip shell 2101, and discharged downward along the bottom of the axis strip shell 2101 under the action of gravity.

[0040] When the sliding outer frame 14 slides, since the top of the water sealing plate 2103 is fixedly connected to the limit baffle 12 through the pressure-sensitive connecting tube 13, the vertical slide bar 15 on the inner wall of the sliding outer frame 14 will slide in a directional manner along the guide groove 2102 on the outer surface of the axis bar shell 2101 to pull the extension belt 35. When the inside of the axis bar shell 2101 is blocked, the torque chassis 27 will twist the vertical tube 23 by 90°, so that the rubber ends 210 on both sides are aligned with the veneer slide plates 2104 on the front and rear sides, thereby pushing the veneer slide plates 2104 to Its sliding rod 2105 is inserted into the guide groove 2102 and squeezed with the vertical slide bar 15. At this time, the sliding outer frame 14 will drive the drainage chamber 21 to rise synchronously through static friction when sliding up, but the pressure-sensitive connecting tube 13 will be squeezed, and the one-way rotating plates 22 on both sides cannot be pushed away by external debris. Then the external traction tube 18 unloads the force, and the sliding outer frame 14 and the drainage chamber 21 slide down synchronously. The objects inside the drainage chamber 21 impact downward under the action of inertia and gravity, thereby clearing the inner cavity of the axis bar shell 2101 and promoting the rapid discharge of internal debris.

[0041] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
