A water quality treatment device for fine diversion of rainwater and flood

Abstract

The present invention discloses a water quality treatment device for fine diversion of rainwater and flood. When the upper cover is opened, water flows from the water inlet trough to the water storage tank. When the upper cover is closed, water flows from the water inlet trough to the upper cover and then to the drainage trough. Subsequent water flows no longer enter the water storage tank, so that the water flow previously entering the water storage tank can be quickly precipitated, thereby realizing fine diversion of rainwater and flood and improving the sedimentation efficiency of the water storage tank. When the filter plate is horizontal, water flows through the filter holes. At this time, the water outlet speed is slow, but the ability to filter debris is strong, which is suitable for working conditions with small rainwater and flood volume. When the filter plate is vertical, water flows through between the two filter plates. The water outlet speed is fast and larger debris can be filtered, which is suitable for working conditions with large rainwater and flood volume. When the filter plate is vertical, smaller debris will enter the water storage tank, and the smaller debris can be salvaged by the cooperation of the winch and the salvage net. The position of the filter plate can be adjusted according to actual working conditions, thereby improving the flexibility of the device.

Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a water quality treatment device for refined diversion of rainwater and flood. Background Art

[0002] Rainwater carries a large amount of pollutants when flowing through the city, affecting the urban ecological environment and the quality of life of residents. Therefore, rainwater quality treatment plays an important role in urban management and environmental protection. In the existing rainwater quality treatment technology, rainwater is first stored in multiple reservoirs, which are connected by overflow pipes. Rainwater flows in multiple reservoirs to form a continuous flow system, which interferes with the natural sedimentation process of suspended matter and pollutants and reduces the sedimentation efficiency of the reservoir.

[0003] Existing stormwater filtering components do not have the ability to adjust. When the amount of stormwater is small, the filtering components may not be able to fully utilize their processing capacity, resulting in a waste of resources. When the amount of stormwater is large, the filtering components may be blocked due to insufficient processing capacity.

[0024] When the filter plate is horizontal, water flows through the filter hole. At this time, the water outlet speed is slow, but the ability to filter debris is strong, which makes full use of the filter plate capacity of the filter plate, and is suitable for working conditions with small rainfall and flood volume.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The present invention provides a technical solution: a water quality treatment device for fine diversion of rainwater and flood, such as Figure 1 , 2 As shown, it includes a plurality of water reservoirs 101, wherein the water reservoirs 101 are provided with an inlet 102, and the inlet 102 is provided with a water inlet trough 103, the water inlet trough 103 can be fixed on the ground, and an upper cover 104 is slidably provided on the inlet 102, and the upper cover 104 can close the inlet 102, Figure 1 The inlet 102 of the middle water reservoir 101 is opened. Figure 2 The inlet 102 of the middle water reservoir 101 is closed.

[0043] like Figure 1 , 2 As shown, a drainage ditch 105 is provided on one side of the inlet 102, and the drainage ditch 105 can be fixed on the ground. A water retaining plate 106 is fixed on the upper cover 104, and the water retaining plate 106 can make the water flowing onto the upper cover 104 flow to the drainage ditch 105, and the drainage ditch 105 can make the water flow to the inlet 102 of other water reservoirs 101.

[0044] like Figure 1 , 3As shown, a plurality of filter plates 107 are rotatably arranged at the entrance 102, each filter plate 107 is provided with a plurality of filter holes, and the plurality of filter plates 107 are arranged in a row. When the filter plates 107 are in a vertical state, the distance between each two filter plates 107 is the same as the width of the entrance 102. When the filter plates 107 are in a horizontal state, adjacent filter plates 107 are in contact with each other.

[0045] A flipping mechanism 200 is provided under the upper cover 104, and the flipping mechanism 200 can rotate the filter plate 107 from a vertical position to a horizontal position. A locking mechanism 300 is provided at the entrance 102, and the locking mechanism 300 can lock the filter plate 107 in a horizontal position. Figure 1 The middle filter plate 107 is in a horizontal position. Figure 3 The middle filter plate 107 is in a vertical position.

[0046] When the filter plate 107 is in a vertical position, the movement of the upper cover 104 can also drive the flipping mechanism 200 to rotate the filter plate 107 to a horizontal position, and the locking mechanism 300 can lock the upper cover 104 in the horizontal position.

[0047] like Figure 2 , 6 As shown in , 7, an incomplete gear 109 is fixed on each filter plate 107, and the flip mechanism 200 includes a flip rack 201, which can mesh with the incomplete gear 109. The flip rack 201 is slidably arranged on the flip bracket 202, and the sliding direction of the flip rack 201 is perpendicular to the length direction of the flip rack 201. The flip bracket 202 is fixed under the upper cover 104. In a cycle from the flip rack 201 and the incomplete gear 109 entering meshing to disengaging meshing, the incomplete gear 109 can rotate 90 degrees. Figure 7 The middle upward-turned rack 201 is located away from the inlet 102 of the water reservoir 101 .

[0048] When the filter plate 107 is horizontal, the upwardly-turned rack 201 can be away from the entrance 102 of the water reservoir 101, so that when the upper cover 104 drives the cleaning brush 108 to clean the filter plate 107, the upwardly-turned rack 201 can be prevented from hitting the incomplete gear 109. When the filter plate 107 is vertical, the upwardly-turned rack 201 can be close to the entrance 102 of the water reservoir 101. When the upper cover 104 drives the cleaning brush 108 to move, the upwardly-turned bracket 202 can move, thereby driving the upwardly-turned rack 201 to move. After the upwardly-turned rack 201 is engaged with the incomplete gear 109, it can drive the incomplete gear 109 to rotate, thereby driving the filter plate 107 to rotate, and then rotating the filter plate 107 to a horizontal position, that is, when the upwardly-turned rack 201 is in a position close to the entrance 102 of the water reservoir 101, the movement of the upwardly-turned rack 201 can drive the filter plate 107 to rotate.

[0049] like Figure 8-10 As shown, a pressure plate 110 is fixed under the upper cover 104, and a roller bracket 203 is fixed on each filter plate 107. Two locking rollers 204 are rotatably arranged on the roller bracket 203. The connecting center line of the two locking rollers 204 is parallel to the filter plate 107. When the filter plate 107 is in a horizontal position, the two locking rollers 204 can contact the pressure plate 110. When the upward rack 201 is disengaged from the incomplete gear 109, the pressure plate 110 moves above the locking rollers 204.

[0050] When the filter plate 107 is in the vertical position, the state of the locking roller 204 is as follows: Fig.10 As shown, when the upward rack 201 is located near the inlet 102 of the water reservoir 101, the movement of the upward rack 201 can drive the filter plate 107 to rotate, so that the filter plate 107 is in a horizontal position. At this time, the state of the locking roller 204 is as shown in FIG. Fig. 9 As shown, after the upward rack 201 is disengaged from the incomplete gear 109, the pressure plate 110 moves to above the locking roller 204, and the pressure plate 110 prevents the roller bracket 203 from rotating, thereby preventing the filter plate 107 from rotating, so that the filter plate 107 remains in a horizontal position.

[0051] like Figure 2 , 5 As shown, a salvage net is provided in the water reservoir 101 for lifting and lowering, and in this embodiment, the salvage net is driven by a winch 402 .

[0052] When the upper cover 104 is opened, water flows from the water inlet trough 103 to the water reservoir 101. When the upper cover 104 is closed, water flows from the water inlet trough 103 to the water baffle 106 of the upper cover 104, and then flows to the drainage trough 105. Subsequent water flows no longer enter the water reservoir 101, so that the water flow previously entering the water reservoir 101 can be quickly settled, thereby realizing the refined diversion of rainwater and improving the sedimentation efficiency of the water reservoir 101.

[0053] When the filter plate 107 is horizontal, water flows through the filter hole. At this time, the water outlet speed is slow, but the ability to filter debris is strong, and the filtering capacity of the filter plate 107 is fully utilized, which is suitable for working conditions with small rainfall and flood volume. When the filter plate 107 is vertical, water flows through between the two filter plates 107, the water outlet speed is fast, and larger debris can be filtered out. The filter plate 107 is not easy to be blocked, which is suitable for working conditions with large rainfall and flood volume. When the filter plate 107 is vertical, smaller debris will enter the reservoir 101, and the smaller debris will be salvaged through the cooperation of the winch 402 and the salvage net. The position of the filter plate 107 can be adjusted according to the actual working conditions, which improves the flexibility of the device. The salvage net is only started under working conditions with large rainfall and flood volume, reducing resource waste.

[0054] When the amount of rainfall is small, the locking mechanism 300 locks the filter plate 107 in a horizontal position, and the upward rack 201 is located away from the entrance 102 of the water reservoir 101. When the upper cover 104 is closed, the upward rack 201 can avoid interference with the incomplete gear 109, so that the upper cover 104 can be closed smoothly.

[0055] When the amount of rainfall and flood is large, the locking mechanism 300 releases the lock on the filter plate 107, the filter plate 107 rotates to a vertical position, and the upward rack 201 moves to a position close to the entrance 102 of the water reservoir 101. When the upper cover 104 is closed, the upward rack 201 rotates the filter plate 107 to a horizontal position through the incomplete gear 109. After the upper cover 104 reaches the end point, the locking mechanism 300 re-locks the filter plate 107, and the upward rack 201 moves to a position away from the entrance 102 of the water reservoir 101 to avoid interference between the upward rack 201 and the incomplete gear 109, so that the upper cover 104 can be opened smoothly.

[0056] The movement of the upper cover 104 and the filter plate 107 can be conveniently controlled by the flipping mechanism 200 and the locking mechanism 300 .

[0057] like Figure 1-4 As shown, a cleaning brush 108 is fixed under the upper cover 104 , and the cleaning brush 108 can clean the horizontal filter plate 107 . When the upper cover 104 moves, the cleaning brush 108 can be driven to clean the horizontal filter plate 107 .

[0058] like Figure 8 As shown, the locking mechanism 300 includes a locking bracket 301, a base bracket 302 is fixed on the water reservoir 101, a locking bracket 301 is slidably provided on the base bracket 302, a plurality of locking forks 303 are fixed on the locking bracket 301, a locking hole is provided at the inlet 102 of the water reservoir 101, and the locking forks 303 can be inserted from the locking hole and penetrate into the bottom of the filter plate 107, Figure 8 The middle locking bracket 301 is located away from the inlet 102 of the water reservoir 101 , and the locking fork 303 does not penetrate under the filter plate 107 .

[0059] When the locking bracket 301 is close to the entrance 102 of the water reservoir 101, the locking fork 303 penetrates into the bottom of the filter plate 107, which can prevent the filter plate 107 from rotating downward and lock the filter plate 107 in a horizontal position. When the locking bracket 301 is away from the entrance 102 of the water reservoir 101, the locking fork 303 disengages from the filter plate 107, releasing the lock on the filter plate 107.

[0060] like Figure 7 , 11As shown, a switching mechanism 500 is provided on the flip-up bracket 202, and the switching mechanism 500 drives the flip-up rack 201 to slide. When the inlet 102 of the water reservoir 101 is opened, the upper cover 104 is at the starting position ( Figure 1 , Figure 3 The upper cover 104 is at the starting position), a starting fork 305 is fixed at one end close to the starting position of the upper cover 104, and when the locking bracket 301 is away from the inlet 102 of the water reservoir 101, the starting fork 305 can drive the switching mechanism 500, and when the inlet 102 of the water reservoir 101 is closed, the upper cover 104 is at the end position ( Figure 2 The middle upper cover 104 is in the end position), and an end fork 304 is fixed to the locking bracket 301 at the end of the upper cover 104 close to the end position of the upper cover 104. When the locking bracket 301 is close to the inlet 102 of the water reservoir 101, the end fork 304 can drive the switching mechanism 500.

[0061] When the locking bracket 301 is away from the entrance 102 of the water reservoir 101, the locking fork 303 disengages from the filter plate 107, and the filter plate 107 is unlocked. The filter plate 107 rotates to a vertical position under the action of its own weight. At this time, the upper cover 104 is at the starting point. The movement of the locking bracket 301 can drive the starting fork 305 to move, and then drive the switching mechanism 500 to make the upward rack 201 close to the entrance 102 of the water reservoir 101. When the upper cover 104 closes the entrance 102, it can drive the movement of the upward rack 201, and then drive the filter plate 107 to rotate, so that the filter plate 107 rotates to a horizontal position.

[0062] After the upper cover 104 reaches the end point, the locking bracket 301 is close to the entrance 102 of the water reservoir 101, and the locking fork 303 penetrates under the filter plate 107 to lock the filter plate 107 in a horizontal position. The movement of the locking bracket 301 can drive the end fork 304 to move, and then drive the switching mechanism 500 to make the upward rack 201 be located away from the entrance 102 of the water reservoir 101. When the upper cover 104 is opened, the upward rack 201 can avoid interference with the incomplete gear 109.

[0063] When the amount of rainfall is small, the locking mechanism 300 locks the filter plate 107 in a horizontal position, and the upward rack 201 is located away from the entrance 102 of the water reservoir 101. When the upper cover 104 is closed, the upward rack 201 can avoid interference with the incomplete gear 109, so that the upper cover 104 can be closed smoothly.

[0064] When the amount of rainfall and flood is large, the locking mechanism 300 releases the lock on the filter plate 107, and the filter plate 107 rotates to a vertical position. At the same time, the switching mechanism 500 is driven to make the upward rack 201 be located near the entrance 102 of the water reservoir 101. When the upper cover 104 is closed, the filter plate 107 is rotated to a horizontal position through the upward rack 201 via the incomplete gear 109. After the upper cover 104 reaches the end point, the locking mechanism 300 re-locks the filter plate 107, and at the same time drives the switching mechanism 500 to make the upward rack 201 be located away from the entrance 102 of the water reservoir 101 to avoid interference between the upward rack 201 and the incomplete gear 109, so that the upper cover 104 can be opened smoothly.

[0065] Through the cooperation of the flipping mechanism 200 , the locking mechanism 300 and the switching mechanism 500 , the movement of the upper cover 104 and the filter plate 107 can be conveniently controlled.

[0066] like Figure 7 , 14 As shown, the switching mechanism 500 includes a switching rack 501, which is fixed on the upper flip rack 201, and the length direction of the switching rack 501 is perpendicular to the length direction of the upper flip rack 201. The switching rack 501 is slidably set on the upper flip bracket 202. The switching rack 501 is meshed and connected with a switching output gear 502, and the switching output gear 502 is rotatably set on the upper flip bracket 202. The switching output gear 502 is connected to the wrench 503 through a speed-increasing gear set, and the wrench 503 is rotatably set on the upper flip bracket 202. The wrench 503 can contact the starting fork 305 or the end fork 304.

[0067] The rotation of the wrench 503 can drive the switching output gear 502 to rotate through the speed-increasing gear set, thereby driving the switching rack 501 to move, and further driving the upward rack 201 to move.

[0068] like Figure 7 , 12 As shown, one end of a tension spring 504 is fixed to the wrench 503, and the other end of the tension spring 504 is fixed to the flip-up bracket 202. The tension spring 504 can keep the wrench 503 in two positions, one of which is close to the inlet 102 of the water reservoir 101, called the extended position ( Fig.12 ), when the wrench 503 is in the extended position, the upturned rack 201 is close to the inlet 102 of the water reservoir 101, and a position away from the inlet 102 of the water reservoir 101 is called the retracted position ( Fig.12 ), when the wrench 503 is in the retracted position, the upward rack 201 is away from the inlet 102 of the water reservoir 101.

[0069] When the wrench 503 is in the retracted position and the upper cover 104 is in the starting position, the movement of the starting fork 305 can drive the wrench 503 to rotate, so that the wrench 503 moves from the retracted position to the extended position, and the tension spring 504 locks the wrench 503 in the extended position.

[0070] When the wrench 503 is in the extended position and the upper cover 104 is in the terminal position, the movement of the terminal fork 304 can drive the wrench 503 to rotate, so that the wrench 503 moves from the extended position to the retracted position, and the tension spring 504 locks the wrench 503 in the retracted position.

[0071] Through the cooperation of the tension spring 504 and the wrench 503, it is easy to drive and control the switching mechanism 500, and the upward rack 201 can be locked at a position close to the entrance 102 of the water tank 101 or at a position away from the entrance 102 of the water tank 101.

[0072] like Fig.11 As shown, the end of the starting fork 305 is L-shaped. When the locking bracket 301 is away from the inlet 102 of the water reservoir 101, the starting fork 305 can hook the movable end of the wrench 503 and drive the wrench 503 to rotate.

[0073] like Figure 7 , 13 As shown, the speed increasing gear includes a pinion 505, which is coaxially fixed on the switching output gear 502, the pinion 505 is meshedly connected with a reversing gear 506, and the reversing gear 506 is rotatably set on the upper flip bracket 202, the reversing gear 506 is meshedly connected with an input gear 507, and the input gear 507 is rotatably set on the upper flip bracket 202, the rotation center of the wrench 503 is fixed on the input gear 507, and the movable end of the wrench 503 is set below the rotation center of the wrench 503.

[0074] The rotation of the wrench 503 can drive the input large gear 507 to rotate, and then drive the reversing large gear 506 to rotate, and then drive the small gear 505 to rotate. The speed increase effect is achieved by the reversing large gear 506 driving the small gear 505, and the stroke of the wrench 503 is enlarged to the stroke of the upward rack 201, so that the wrench 503 can control the movement of the upward rack 201 with a smaller stroke, which is convenient for driving and controlling the wrench 503.

[0075] like Figure 7 , 8 As shown, the locking bracket 301 is driven by an electric push rod 306 , and the electric push rod 306 is fixed on the base bracket 302 .

[0076] The shortening of the electric push rod 306 can drive the locking bracket 301 away from the inlet 102 of the water reservoir 101 , and the extension of the electric push rod 306 can drive the locking bracket 301 close to the inlet 102 of the water reservoir 101 .

[0077] like Figure 4 As shown, in order to realize the sliding of the upper cover 104 on the entrance 102 of the water reservoir 101, a plurality of pairs of driven wheels and driving wheels are rotatably arranged under the upper cover 104, and the driven wheels and driving wheels are rollingly arranged on the entrance 102 of the water reservoir 101, and the driving wheels are driven by a driving motor 111, and the driving motor 111 is fixed under the upper cover 104.

[0078] The driving motor 111 can drive the driving wheel to rotate, thereby driving the upper cover 104 to move, and further driving the driven wheel to rotate.

[0079] like Figure 5 As shown, the salvage net is fixed on a salvage bracket 401 , the salvage bracket 401 is slidably arranged on a guide rail 403 , the guide rail 403 is fixed in the reservoir 101 , the salvage bracket 401 is rope-connected to a winch 402 , and the winch 402 is fixed on a base bracket 302 .

[0080] The winch 402 can drive the salvage support 401 to rise, thereby driving the salvage net to rise, and salvage smaller debris in the reservoir 101.

[0081] A liquid level meter is fixed on the base support 302 . In this example, the liquid level meter is an ultrasonic liquid level meter, which is used to monitor the water level in the water reservoir 101 .

[0082] Working process: In the initial state, the upper cover 104 is at the starting position, the inlet 102 of the water reservoir 101 is open, the wrench 503 of the switching mechanism 500 is in the retracted position, the locking fork 303 of the locking mechanism 300 is inserted into the locking hole at the inlet 102 of the water reservoir 101 and penetrates under the filter plate 107, and the filter plate 107 is locked in a horizontal position by the locking mechanism 300.

[0083] Under the condition of less rain and flood, water flows into the water reservoir 101 through the water inlet groove 103. When the water reservoir 101 reaches the set water level, the upper cover 104 is closed, and the water flows to the upper cover 104 and is guided to the drainage groove 105 by the water retaining plate 106, and then diverted to other water reservoirs 101. The water in the closed water reservoir 101 begins to settle. When the upper cover 104 is closed, the drive motor 111 is started, driving the upper cover 104 to move, and then driving the cleaning brush 108 to clean the filter plate 107.

[0084] Under the working condition of heavy rain and flood, the upper cover 104 is at the starting position, the entrance 102 of the water reservoir 101 is opened, the wrench 503 of the switching mechanism 500 is in the retracted position, and the electric push rod 306 is shortened, thereby driving the locking bracket 301 away from the entrance 102 of the water reservoir 101, and then driving the locking fork 303 to disengage from the filter plate 107, releasing the lock of the filter plate 107, and the filter plate 107 rotates to a vertical position under the action of its own weight, and the water flows into the water reservoir 101 through the water inlet trough 103. When the water reservoir 101 reaches the set water level, the upper cover 104 is closed, and the water flows to the upper cover 104 and is guided to the drainage trough 105 by the water retaining plate 106, and then diverted to other water reservoirs 101. At the closed water reservoir 101, the winch 402 drives the salvage bracket 401 to rise, thereby driving the salvage net to rise, and salvages smaller debris in the water reservoir 101.

[0085] When the electric push rod 306 is shortened and drives the locking bracket 301 away from the entrance 102 of the water reservoir 101, the movement of the locking bracket 301 drives the starting fork 305 to move, thereby driving the wrench 503 to rotate. The rotation of the wrench 503 can drive the switching output gear 502 to rotate through the speed-increasing gear set, thereby driving the switching rack 501 to move, and then driving the upward rack 201 to move toward the entrance of the water reservoir 101, so that the wrench 503 of the switching mechanism 500 moves from the retracted position to the extended position.

[0086] When the upper cover 104 is closed, the drive motor 111 is started, driving the upper cover 104 to move, thereby driving the upward rack 201 to engage with the incomplete gear 109, and then driving the filter plate 107 to rotate. After the upward rack 201 is disengaged from the incomplete gear 109, the filter plate 107 rotates to a horizontal position, and at the same time, the pressure plate 110 moves to above the locking roller 204 to prevent the filter plate 107 from rotating again, so that the filter plate 107 remains in a horizontal position, and then the cleaning brush 108 moves to the filter plate 107 that has been turned to a horizontal position, thereby cleaning the filter plate 107.

[0087] After the upper cover 104 reaches the end position, the electric push rod 306 extends to drive the locking bracket 301 to move, and the movement of the locking bracket 301 drives the end fork 304 to move, thereby driving the wrench 503 to rotate. The rotation of the wrench 503 can drive the switching output gear 502 to rotate through the speed-increasing gear set, thereby driving the switching rack 501 to move, and then driving the upward rack 201 away from the entrance 102 near the water tank 101, so that the switching mechanism 500 moves from the extended position to the retracted position.

[0088] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
