[0002] Drain board is a key construction board laid between the base layer and the construction layer. Its core function is water seepage and drainage. It is widely used in various operation scenarios such as greening projects, construction projects, and water conservancy projects. The structure of the drain board mainly includes a base plate and several conical bosses arranged on the base plate. The gaps between these bosses are connected to form a drainage channel. The accumulated water is discharged through the drainage channel to ensure the stability and safety of the project.

DETAILED DESCRIPTION

[0047] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0048] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0049] Embodiment 1:

[0050] like Figure 1 , Figure 2 As shown, the present invention provides a water storage type drainage board, comprising:

[0051] A drainage board 1, on which a plurality of drainage grooves are evenly arranged;

[0052] A water storage plate 2, the water storage plate 2 is arranged above the drainage plate 1;

[0053] Support seats 3, multiple support seats 3 are evenly connected between the drainage board 1 and the water storage board 2, and a water inlet is arranged at the top of the support seats 3;

[0054] The water storage pipe 4 is connected to both sides of the support seat 3 , and a plurality of water storage pipes 4 form a water storage pipe network. An overflow component is arranged on the water storage pipe 4 .

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] When a water storage type drainage board is used in an underground drainage system such as urban greening, when it rains, water will accumulate above the water storage board 2, and the accumulated water will enter the interior through the water inlet on the top of the support seat 3, and flow into the water storage pipe 4, and then the accumulated water will be stored in the support seat 3 and the water storage pipe 4. Through the water storage pipe network composed of the water storage pipe 4, the stored water will be transported to the location where water is needed or returned to the water tank, so as to reserve water resources for subsequent use, for example, it can provide water for plant roots during drought; when the amount of water in the water storage pipe 4 exceeds the preset amount of water, it will flow out through the overflow assembly on the water storage pipe 4, fall on the drainage board 1, and be discharged outward through the drainage groove on the drainage board 1.

[0057] Through the above-mentioned structural design, a hollow support seat 3 is used to connect the drainage board 1 and the water storage board 2, and the support seat 3 provides support for the drainage board 1 to avoid collapse when it is pressed or stepped on; and the water storage function is integrated on the drainage board 1 to store a certain amount of water resources while draining water; the water storage pipe 4 is connected to the support seat 3, and there is no need to set up an additional water storage box, so that the drainage channel space in the drainage board 1 and the water storage board 2 is sufficient to ensure a smooth drainage process; the formed water storage pipe network can evenly distribute the stored water resources in the drainage board, which is convenient for the storage and allocation of water resources and improves the utilization rate of water resources.

[0058] Embodiment 2:

[0059] like Figure 3-Figure 8 As shown, on the basis of the above-mentioned embodiment 1, the support seat 3 includes an outer seat body 11 and an inner seat body 12, and the inner seat body 12 is nested in the outer seat body 11; the top of the outer seat body 11 is flush with the top of the water storage plate 2, a water inlet is set at the top of the outer seat body 11 and a conical guide port 13 is set at the edge of the water inlet, and the bottom end of the outer seat body 11 is connected to the installation groove of the drainage board 1; the top of the inner seat body 12 is open and water outlets are set on both sides, and the water outlets are connected to the side of the water storage pipe 4.

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] The support seat 3 is set as a nested hollow structure, and the support seat 3 includes an outer seat body 11 and an inner seat body 12 embedded therein; one side of the outer seat body 11 can be opened to facilitate the embedded installation of the inner seat body 12. The support seat 3 supports the water storage board 2. Since the support seat 3 adopts a hollow structure, it will produce insufficient strength. Therefore, the nested structure is adopted to improve the support strength of the support seat 3, reduce the collapse deformation caused by pressure and stepping, and help maintain the stability of the drainage board structure. A conical guide port 13 is set at the top of the outer seat body 11. When there is water accumulation above the water storage board 2, the water flow will converge to the water inlet of the outer seat body 11 along the conical guide port 13, flow into the outer seat body 11, and then flow downward into the inner seat body 12, flow out from the water outlets on both sides of the inner seat body 12, and enter the water storage pipes 4 on both sides for storage. When installing the support seat 3, align the bottom of the outer seat body 11 with the installation groove for installation.

[0062] Embodiment 3:

[0063] like Figure 3-Figure 6 As shown, based on the above embodiment 2, the overflow assembly includes:

[0064] A lifting rod 14, wherein the lifting rod 14 is arranged in an N-shape, wherein a first end of the lifting rod 14 vertically extends into the top of the water storage pipe 4, and a second end of the lifting rod 14 vertically extends to the outer side of the water storage pipe 4;

[0065] A floating plate 15, the floating plate 15 is connected to the first end of the lifting rod 14;

[0066] The baffle 16 is connected to the second end of the lifting rod 14 , and the baffle 16 blocks the overflow port 17 on the outer side of the water storage pipe 4 .

[0067] The working principle and beneficial effects of the above technical solution are:

[0068] When the drainage plate is storing water, the floating plate 15 is located at a lower position under the gravity of itself and the lifting rod 14 and the baffle 16 connected thereto, and does not contact the water surface. The baffle 16 blocks the overflow port 17 on the outside of the water storage pipe 4; when the water flows into the support seat 3, it can be stored inside the water storage pipe 4 to realize the water storage function. When the water level in the water storage pipe 4 gradually rises, the buoyancy of the water on the floating plate 15 increases, and the floating plate 15 will move upward with the rise of the water level. When the water level rises to a certain height, the floating plate 15 drives the baffle 16 to rise through the lifting rod 14 and fully opens the overflow port 17. At this time, the excess water in the water storage pipe 4 will be discharged through the overflow port 17. When the water level drops, the buoyancy of the floating plate 15 decreases and then falls back, and the baffle 16 is driven by the lifting rod 14 to re-block the overflow port 17.

[0069] Through the above-mentioned structural design, after a preset amount of water is stored in the support seat 3 and the water storage pipe 4, the overflow port 17 is automatically opened for drainage through the linkage of the float plate 15 and the baffle plate 16, so that excess water in the water storage pipe 4 overflows, and the water storage amount is accurately controlled to ensure the flexible connection between the water storage process and the drainage process.

[0070] Embodiment 4:

[0071] like Figure 3-Figure 6 As shown, based on the above-mentioned embodiment 1, the water storage pipe 4 is connected to the middle part of the outer base body 11, a gap is provided between the bottom end of the water storage pipe 4 and the drainage board 1, and a gap is provided between the top end of the water storage pipe 4 and the water storage board 2.

[0072] The working principle and beneficial effects of the above technical solution are:

[0073] The water storage pipe 4 is arranged between the drain board 1 and the water storage board 2, and a gap is arranged between the water storage pipe 4 and the water storage board 2 to provide space for the overflow component to move; a gap is arranged between the water storage pipe 4 and the drain board 1 to increase the water receiving space above the drain board 1, and the water storage pipe 4 does not contact the drain board 1 and will not block the water flow, so that the overflow water can quickly flow out through the drainage groove on the drain board 1.

[0074] Embodiment 5:

[0075] like Figure 3-Figure 8 As shown, based on the above embodiment 2, the inner seat body 12 includes:

[0076] The flow guiding cavity 21 is arranged at the upper part of the inner seat body 12, arc-shaped flow channels 22 are arranged on both sides of the flow guiding cavity 21, and water outlets are formed at the ends of the arc-shaped flow channels 22;

[0077] The transmission chamber 23 is arranged at the lower part of the inner seat body 12;

[0078] The transmission chamber 23 and the guide chamber 21 are separated by a partition 24, and the center of the partition 24 protrudes upward and is provided with a through hole;

[0079] A ball seat 25, the ball seat 25 is connected to the through hole in the center of the partition plate 24;

[0080] The ball 26 is rotatably connected to the ball seat 25, and a sealing gasket is provided between the ball 26 and the ball seat 25;

[0081] A spoiler 27, the spoiler 27 is connected to the sphere 26 at an angle;

[0082] Motor 28, motor 28 is installed in the transmission cavity 23, the output shaft of motor 28 is coaxially arranged with the axis of sphere 26, and motor 28 is electrically connected to the controller;

[0083] A rotating rod 29, the rotating rod 29 is connected to the bottom end of the sphere 26, and the rotating rod 29 is arranged vertically with the spoiler 27;

[0084] The bent rod 30 has two ends connected to the output shaft of the motor 28 and the rotating rod 29 respectively.

[0085] The working principle and beneficial effects of the above technical solution are:

[0086] When the water flows into the inner seat body 12, it flows along the arc flow channels 22 on both sides of the guide cavity 21, enters the water storage pipe 4, and flows into the water storage network through the water storage pipe 4, so that the stored water is evenly distributed; the arc flow channel 22 is set to be arc-shaped, and the middle part is higher than the two sides, so that the water flows out from the water outlet at the end more concentratedly, ensuring the water storage and drainage effects. A transmission chamber 23 is set at the lower part of the inner seat body 12. When the precipitation or the amount of water accumulated above the water storage plate 2 exceeds a preset value, the motor 28 is started to rotate its output shaft. The motor 28 drives the rotating rod 29 to rotate through the bent rod 30, and then drives the ball 26 to rotate in the ball seat 25; a sealing gasket is set on the ball seat 25 to prevent water from flowing out from between the gas 25 and the ball seat 25; the spoiler 27 rotates synchronously with the ball 26, and the inclined spoiler 27 stirs the water flow during rotation, increases the water flow velocity, and makes the water flow flow into the water storage pipe 4 along the spoiler 27 panel, reducing the risk of water accumulation above the water storage plate 2; at the same time, under the action of the disturbance, the water flow is more evenly distributed, avoiding the situation where too much water in a single water storage pipe 4 overflows prematurely, and effectively ensuring the water storage effect.

[0087] Embodiment 6:

[0088] like Figure 7 As shown, based on the above-mentioned embodiment 5, a lateral spoiler component is provided on the spoiler 27, and the lateral spoiler component includes:

[0089] A chute 31, wherein two chute 31 are symmetrically arranged on both sides of the spoiler 27;

[0090] The lateral spoiler 32 is slidably connected in the slide groove 31 , and a spring 33 is connected between the lateral spoiler 32 and the end of the slide groove 31 .

[0091] The working principle and beneficial effects of the above technical solution are:

[0092] When water flows into the inner seat body 12, the water flows impact the spoiler 27 and pushes the transverse spoiler 32 to slide along the slide groove 31, and the sliding direction is along the inclination direction of the spoiler 27. When the transverse spoiler 32 slides, it stores energy for the spring 33. When the water flow becomes smaller or disappears, the transverse spoiler 32 is reset. Through the reciprocating motion of the transverse spoiler 32, the water flow can be better pushed into the water storage pipe 4, which helps to improve the efficiency of drainage and water storage and avoid the problem of local water accumulation or poor drainage.

[0093] Embodiment 7:

[0094] like Figure 6-Figure 8 As shown, on the basis of the above-mentioned embodiment 5, a clamping ring 34 is connected to the top of the outer base body 11, and a filter screen plate 35 is connected to the center of the clamping ring 34.

[0095] The working principle and beneficial effects of the above technical solution are:

[0096] During the drainage and water storage process, water flows into the support seat 3 through the snap ring 34 at the top of the outer seat body 11. When the water flows through the snap ring 34, the filter plate 35 filters the water to filter out sand, gravel and other debris to prevent them from entering the support seat 3 and causing blockage and erosion, thereby ensuring the normal operation of the drainage and water storage systems.

[0097] Embodiment 8:

[0098] like Figure 6-Figure 8 As shown, on the basis of the above-mentioned embodiment 7, elastic telescopic tubes 36 are symmetrically connected to the two sides of the clamping ring 34, the elastic telescopic tubes 36 are telescopic in the vertical direction, and the outside of the elastic telescopic tubes 36 is surrounded by an airbag; the bottom end of the elastic telescopic tube 36 is connected to a pressure ball 37, and the pressure ball 37 is crimped on the top of the spoiler 27.

[0099] A plurality of ventilation chambers 38 are arranged in the clamp ring 34 , a first ventilation port of the ventilation chamber 38 is connected to the inside of the airbag, and a second ventilation port of the ventilation chamber 38 is connected to the external environment; a plurality of resonance plates 39 are arranged in the ventilation chamber 38 .

[0100] The working principle and beneficial effects of the above technical solution are:

[0101] When the spoiler 27 rotates with the spherical body 26, the pressure ball 37 above the spoiler 27 will be affected by the movement of the spoiler 27 and move up and down. The pressure ball 37 is connected to the bottom end of the elastic telescopic tube 36, and the up and down movement of the pressure ball 37 will squeeze the elastic telescopic tube 36 to expand and contract in the vertical direction. When the elastic telescopic tube 36 is squeezed, the pressure of the gas in the airbag will change. Among them, the pressure ball 36 in contact with the higher side of the spoiler 27 is squeezed and moved upward, so that the elastic telescopic tube 36 is compressed, the air pressure in the airbag increases, the airflow enters the ventilation cavity 38 through the first ventilation port and flows out through the second ventilation port, and the resonance plate 39 vibrates during the airflow flow; the pressure ball 36 in contact with the lower side of the spoiler 27 moves downward, so that the elastic telescopic tube 36 is extended, the air pressure in the airbag decreases, the airflow enters the ventilation cavity 38 through the second ventilation port under the action of negative pressure, and flows into the airbag through the first ventilation port, and the resonance plate 39 vibrates during the airflow flow; the vibration is transmitted to the clamping ring 34 through the resonance plate 39, so that the filter plate 35 vibrates accordingly, and the debris blocked on the mesh of the filter plate 35 is shaken out, reducing the risk of blockage of the filter plate 35, and ensuring the normal progress of the water storage and drainage process. At the same time, the elastic telescopic tube 36 is always pressed on the spoiler 27, which helps to maintain its stability during the rotation of the spoiler 27 and reduce the deformation and displacement caused by the impact of the water flow on the spoiler 27.
