Description

Technical Field

[0001] This utility model relates to the field of urban water storage technology, specifically a water storage and purification device with a slow-release device. Background Technology

[0002] In the field of sponge city construction, maintaining stable water levels is crucial for urban hydrological and ecological balance, flood prevention, and water resource recycling. Based on the functional requirements of sponge cities—"water absorption, storage, infiltration, purification, and release"—stored rainwater must be released evenly and slowly during non-rainfall periods to match urban water demand and ecological water replenishment rhythm.

[0003] Currently, the industry generally adopts a pump-driven mechanized water release solution, using a control system to adjust the pump speed or start / stop frequency to achieve flow control. However, this technical approach has significant limitations: on the one hand, in remote areas without power grid coverage, ecologically sensitive areas, or old urban area renovation scenarios, the availability of power sources and the installation of electromechanical equipment are scarce, resulting in poor feasibility of the solution; on the other hand, even in scenarios with available power, the purchase, installation, and maintenance costs of pump units are high, and regular inspections by professional technicians are required, increasing the full life-cycle management costs of sponge cities. Furthermore, the operation of electromechanical equipment may generate noise pollution and energy loss, which conflicts to some extent with the green and low-carbon construction concept of sponge cities.

[0004] Therefore, how to achieve uniform and slow release of rainwater without the intervention of external power, while reducing the construction and operation and maintenance costs of the system, has become a technical problem that urgently needs to be solved in the field of sponge city water management. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses a regulating and purifying device with a slow-release device.

[0006] This utility model provides a regulating and purifying device with a slow-release device, including a water storage tank, which has a water inlet at the upper end and a drain pipe at the lower end.

[0007] A slow-release device is installed inside the water storage tank, and the slow-release device is equipped with a drain hole that communicates with the inner cavity of the water storage tank.

[0008] The slow-release device includes a slow-release cylinder, on which a water inlet pipe communicating with its inner cavity is provided, and an external float ball is connected to the outer end of the water inlet pipe;

[0009] The water inlet pipe is located near the external float and has an inlet hole that communicates with the inner cavity of the water storage tank.

[0010] The water inlet is located below the liquid level in the water storage tank.

[0011] The beneficial effects of the above setup are: 1. By installing a slow-release device with a drain hole in the water storage tank, and a water inlet pipe that communicates with the inner cavity of the slow-release cylinder and is connected to an external float, rainwater can be released evenly and slowly without the intervention of external power; 2. The position of the water inlet hole ensures that the flow rate of water entering the slow-release device remains stable, thereby ensuring that the flow rate of water discharged from the slow-release device also remains stable; 3. Using a slow-release device instead of a traditional water pump reduces costs and noise.

[0012] Because the inlet pipe is relatively soft, the inlet hole is prone to deformation, which causes changes in the flow area of ​​the inlet hole and thus affects the stability of the water flow. Based on this, a further improvement is made by connecting the inlet pipe and the external float ball through a connector; the connector is made of a rigid material; and the inlet hole is located on the connector.

[0013] To maintain a stable water volume inside the slow-release cartridge, a further design feature is the installation of a hinged inner float inside the cartridge; the inner float, unaffected by buoyancy, blocks the drain hole.

[0014] Water storage tanks are typically manufactured using one-piece injection molding, which results in relatively high costs. Therefore, a further improvement involves: the water storage tank comprising a U-shaped, upward-opening body; U-shaped end plates snapping into both ends of the body; a water inlet located on the body; and a drain pipe mounted on the end plates. Specifically, the snapping structure consists of: U-shaped grooves at both horizontal ends of the body, extending along a U-shaped path; and end plates with snapping plates that engage these grooves.

[0015] Because the contact area between the end plate and the tank body is large, the clamping plate and the clamping slot are generally connected by a loose fit to facilitate assembly. Moreover, the tank body is U-shaped and has a strong deformation capacity. As a result, the external dimensions of the water storage tank will have a large deviation. Based on this, the further improvement is as follows: a first clamping hole extending vertically is provided at the upper end of the tank body; a second clamping hole extending vertically is provided at the upper end of the end plate, near the tank body; and a U-shaped clamping rod is provided, with one end clamping the first clamping hole and the other end clamping the second clamping hole.

[0016] The contact area between the locking rod and the first and second locking holes directly affects the structural stability of the locking rod. Based on this, a further improvement is made: the housing is provided with a raised first locking block, and the first locking hole is located on the first locking block; the end plate is provided with a raised second locking block, and the second locking hole is located on the second locking block.

[0017] Because the enclosure is U-shaped, its strength is low and its positional stability after installation is not high. Based on this, a further improvement is made: the outer wall of the enclosure is provided with a raised, U-shaped reinforcing plate; multiple reinforcing plates are provided and are evenly spaced along the axial direction of the enclosure.

[0018] The positional accuracy of the drain pipe directly affects the connection accuracy between it and the drain hole. Based on this, a further improvement is made: a downwardly recessed limiting groove is provided at the bottom of the box; the drain pipe is snapped into the limiting groove.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] like Figure 1 and Figure 4 As shown, this utility model discloses a water storage and purification device with a slow-release device, including a water storage tank 1. The water storage tank 1 is composed of a tank body 103 and two symmetrically arranged end plates 104; the tank body 103 is U-shaped with the opening facing upwards, as shown in the figure. Figure 2 The tank body 103 has U-shaped grooves 105 at both ends, with U-shaped end faces and U-shaped extension paths. The end plate 104 is U-shaped to match the tank body 103, and its outer end face has a protruding locking plate 106 that engages with the grooves 105. This not only facilitates the installation of the water tank 1, but also reduces the injection molding difficulty and cost compared to the traditional one-piece injection molding of the water tank 1. After the tank body 103 and the end plate 104 are engaged, they are connected and fixed by hot melt welding to achieve a seal. The upper end face of the end plate 104 is flush with the upper end face of the tank body 103.

[0031] A water inlet 101 is provided at the upper end of one side of the tank 103, through which rainwater flows into the water storage tank 1. A horizontally arranged drain pipe 102 is provided at the lower end of the end plate 104, and the outer end of the drain pipe 102 is connected to the water body through a pipeline, so that the water in the water storage tank 1 flows into the water body.

[0032] To improve the positional accuracy of the drain pipe 102, such as Figure 8 As shown, the lower end of the box 103 is provided with a downwardly recessed limiting groove 112, and the drain pipe 102 is snapped into the limiting groove 112.

[0033] The outer wall of the tank 103 is provided with a raised, U-shaped reinforcing plate 111; multiple reinforcing plates 111 are provided and are evenly spaced along the axial direction of the tank 103. The reinforcing plates 111 not only improve the structural strength of the tank 103, but also, when the water storage tank 1 is installed, the foundation filler will fill the groove formed between adjacent reinforcing plates 111, thereby improving the installation structural stability of the water storage tank 1.

[0034] Because the contact area between the end plate 104 and the tank body 103 is large, the locking plate 106 and the locking groove 105 are connected by a loose fit to facilitate the snap-fit ​​between the end plate 104 and the tank body 103. Furthermore, the tank body 103 is U-shaped and has strong deformation capacity. As a result, the external dimensions of the water storage tank 1 will deviate significantly. To solve this technical problem, the following design is made: Figure 5As shown, the upper end of the tank 103 is provided with a downwardly extending first locking block 109, and the first locking block 109 is provided with a vertically extending first locking hole 107; the upper end of the end plate 104, near the tank 103, is provided with a second locking block 110, and the second locking block 110 is provided with a vertically extending second locking hole 107; one end of the U-shaped locking rod 113 engages with the first locking hole 107, and the other end engages with the second locking hole 107. By engaging the locking hole with the locking rod 113, the shape of the tank 103 is corrected, resulting in higher dimensional accuracy of the water storage tank 1. The provision of the first locking block 109 and the second locking block 110 increases the depth of the first locking hole 107 and the second locking hole 107, and increases the contact area between the locking rod 113 and the first locking hole 107 and the second locking hole 107, resulting in higher structural strength of the locking rod 113 engaging the tank 103 and the end plate 104. The snap-fit ​​rod 113 is arranged with its opening facing downward and is hidden in the groove formed by the connection between the housing 103 and the end plate 104, so that the top of the snap-fit ​​rod 113 is flush with or lower than the top of the housing 103, so that the snap-fit ​​rod 113 will not obstruct the installation of the cover plate of the top plate of the housing 103.

[0035] A slow-release device 2 is installed inside the water storage tank 1. The slow-release device 2 includes a slow-release cylinder 201, the lower end of which is provided with a drain hole 206, which is connected to a drain pipe 102 via a pipeline. A water inlet pipe 202 is connected to the side wall of the slow-release cylinder 201. Figure 3 As shown, one end of the inlet pipe 202 is connected to the inner cavity of the slow-release cylinder 201, and the other end is connected to an external float 203 via a connector 205. The connector 205 includes a cylindrical body, one end of which is provided with a screw that is threadedly connected to the external float 203, and the other end of which is provided with a tower-shaped connecting pipe that is inserted into the inlet pipe 202 and fixed by an interference fit to achieve a seal. The side wall of the body has four circumferentially distributed inlet holes 204. The connector 205 floats under the action of the float, and the inlet holes 204 are located below the liquid surface of the water storage tank 1, so that the flow rate of water entering the slow-release device 2 remains stable, and thus the flow rate of water discharged from the slow-release device 2 also remains stable. Moreover, by setting the slow-release device 2 with a drain hole 206 in the water storage tank 1, and the inlet pipe 202 that is connected to the inner cavity of the slow-release cylinder 201 and the external float 203, the rainwater is released evenly and slowly without the intervention of external power.

[0036] The slow-release cylinder 201 is also equipped with a hinged inner float 207; the inner float 207, when not under buoyancy, blocks the drain hole 206. When the water volume in the slow-release tank 103 increases, causing the inner float 107 to rise due to buoyancy, the inner cavity of the slow-release tank 103 connects with the drain hole 206 to drain water; moreover, as the water volume in the slow-release tank 103 continues to increase, the rising height of the inner float 107 also increases, and the flow area of ​​the flow channel between the inner cavity of the slow-release tank 103 and the drain hole 206 also increases, thus keeping the water volume in the slow-release tank 103 stable. The lower end of the inner float 207 is a convex arc shape, allowing water to enter the area between the inner float 207 and the bottom surface of the slow-release cylinder 201, thus enabling the inner float 207 to float stably.

[0037] The specific installation structure of the internal float 207 is as follows: Figure 6 and Figure 7 As shown, the side wall of the slow-release cylinder 201 has a through hole 211. A mounting bracket 208 is installed inside the slow-release cylinder 201. The lower right end of the mounting bracket 208 is hinged to one end of a connecting plate 209, and the other end of the connecting plate 209 is fixedly connected to an inner float 207. A horizontally arranged threaded tube 210 with external threads extends from the left end of the mounting bracket 208. The threaded tube 210 passes through the through hole 211 and extends to the left out of the slow-release cylinder 201. A locking nut 213 is threaded onto the threaded tube 210 to lock and fix the mounting bracket 208. Sealing rings 212 are provided on both the inner and outer sides of the through hole 211 to fit the threaded tube 210, achieving a seal at the through hole 211. A washer 214 is also provided between the locking nut 213 and the sealing ring 212 to prevent scratching of the sealing ring 212 when the locking nut 213 is tightened.

[0038] The lower end of the water inlet pipe 202 is provided with a movable connecting nut 215. When the connecting nut 215 is threadedly connected to and locked with the threaded pipe 210, the lower end of the water inlet pipe 202 is close to the outer end of the threaded pipe 210, thereby achieving the connection and fixation of the water inlet pipe 202 and also achieving a sealed connection between the water inlet pipe 202 and the threaded pipe 210.

[0039] Compared with the prior art, the advantages of this embodiment are: by setting a slow-release device 2 with a drain hole 206 in the water storage tank 1, and a water inlet pipe 202 that communicates with the inner cavity of the slow-release cylinder 201 and is connected to the outer float 203, etc., rainwater can be released evenly and slowly without the intervention of external power, thereby replacing the traditional water pump, reducing costs and noise.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
