[0002] Drainage 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 drainage 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.

[0047] The present invention will be further described in detail below with reference to 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 terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0049] Example 1:

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

[0051] Drain board 1, multiple drainage grooves are evenly arranged on the drain board 1;

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

[0053] Support base 3, multiple support bases 3 are evenly connected between the drainage plate 1 and the water storage plate 2, and a water inlet is provided at the top of the support base 3;

[0054] Water storage pipe 4, water storage pipe 4 is connected to both sides of the support base 3, multiple water storage pipes 4 form a water storage pipe network, and an overflow component is set 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 that of urban greening, when rainfall occurs, water will accumulate above the water storage board 2. The accumulated water enters the interior of the support base 3 through the water inlet on the top of the support base 3 and flows into the water storage pipe 4, and then the accumulated water is stored in the support base 3 and the water storage pipe 4. The stored water is transported to a location where water is needed or returned to the water tank through the water storage pipe network composed of the water storage pipe 4, thereby reserving water resources for subsequent use. For example, it can provide water for plant roots during droughts. When the amount of water in the water storage pipe 4 exceeds the preset amount of water, it flows out through the overflow assembly on the water storage pipe 4, falls on the drainage board 1, and is 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 under pressure or stepped on; and the water storage function is integrated into 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, facilitate the storage and allocation of water resources, and improve the utilization rate of water resources.

[0058] Example 2:

[0059] like Figure 3-Figure 8 As shown, based on 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, and 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 outlet is 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 base 3 is designed as a nested hollow structure, comprising an outer base 11 and an inner base 12 embedded within it. The outer base 11 has an opening on one side to facilitate the insertion and installation of the inner base 12. The support base 3 supports the water storage plate 2. Since the support base 3 is hollow, it would lack strength. Therefore, the nested structure improves the support strength of the support base 3, reduces deformation caused by pressure and footsteps, and helps maintain the stability of the drainage plate structure. A conical guide port 13 is provided at the top of the outer base 11. When water accumulates above the water storage plate 2, the water flows along the conical guide port 13 to the water inlet of the outer base 11, flows into the outer base 11, and then flows downward into the inner base 12. It then flows out through the water outlets on both sides of the inner base 12 and enters the water storage pipes 4 on both sides for storage. To install the support base 3, align the bottom of the outer base 11 with the mounting slot.

[0062] Example 3:

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

[0064] The lifting rod 14 is configured as an N-type, wherein the first end of the lifting rod 14 vertically extends into the top of the water storage pipe 4, and the second end of the lifting rod 14 vertically extends to the outer side of the water storage pipe 4;

[0065] 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 drain plate is storing water, the float 15 is located at a lower position under the action of the gravity of itself and the lifting rod 14 and baffle 16 connected to it, and does not come into contact with 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 achieve the water storage function. When the water level in the water storage pipe 4 gradually rises, the buoyancy of the water on the float 15 increases, and the float 15 will move upward as the water level rises. When the water level rises to a certain height, the float 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 float 15 decreases and it 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 16, so that the 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] Example 4:

[0071] like Figure 3-Figure 6 As shown, based on the above embodiment 1, the water storage pipe 4 is connected to the middle 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 set between the water storage pipe 4 and the water storage board 2 to provide space for the overflow component to move; a gap is set 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 flow out quickly through the drainage groove on the drain board 1.

[0074] Example 5:

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

[0076] The diversion cavity 21 is provided on the upper portion of the inner seat 12. Curved flow channels 22 are provided on both sides of the diversion cavity 21, and water outlets are formed at the ends of the curved flow channels 22.

[0077] The transmission chamber 23 is provided at the lower portion 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] 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 is connected obliquely to the sphere 26;

[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 is connected to the bottom end of the sphere 26 and is arranged perpendicular to 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 diversion cavity 21, enters the water storage pipe 4, and flows into the water storage pipe 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 flow is more concentrated and flows out from the water outlet at the end, ensuring the water storage and drainage effects. A transmission chamber 23 is provided 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 provided 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 along the spoiler 27 panel to the water storage pipe 4, 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] Example 6:

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

[0089] The two chutes 31 are symmetrically arranged on both sides of the spoiler 27;

[0090] The transverse spoiler 32 is slidably connected to the slide groove 31 , and a spring 33 is connected between the transverse 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] Example 7:

[0094] like Figure 6-Figure 8 As shown, based on the above 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, the water flow will enter the support seat 3 through the clamping ring 34 at the top of the outer seat body 11. When the water flows through the clamping ring 34, the filter plate 35 filters the water flow, filtering 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] Example 8:

[0098] like Figure 6-Figure 8 As shown, based on the above-mentioned embodiment 7, elastic telescopic tubes 36 are symmetrically connected to both 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 pressed on the top of the spoiler 27.

[0099] A plurality of ventilation cavities 38 are provided in the clamp ring 34 . A first ventilation port of the ventilation cavity 38 is connected to the interior of the airbag, and a second ventilation port of the ventilation cavity 38 is connected to the external environment. A plurality of resonance plates 39 are provided in the ventilation cavity 38 .

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

[0101] As spoiler 27 rotates with sphere 26, pressure ball 37 above spoiler 27 is affected by the movement of spoiler 27 and moves up and down. Pressure ball 37 is connected to the bottom end of elastic telescopic tube 36. The up and down movement of pressure ball 37 squeezes elastic telescopic tube 36, causing it to expand and contract vertically. When elastic telescopic tube 36 is squeezed, it causes pressure changes in the gas within the airbag. The pressure ball 36 in contact with the higher side of the spoiler 27 is squeezed upward, compressing the elastic tube 36 and increasing the air pressure within the airbag. Air flows through the first ventilation port into the ventilation chamber 38 and out through the second ventilation port, causing the resonant plate 39 to vibrate during the flow. The pressure ball 36 in contact with the lower side of the spoiler 27 moves downward, extending the elastic tube 36 and reducing the air pressure within the airbag. Under the action of negative pressure, air flows through the second ventilation port into the ventilation chamber 38 and into the airbag through the first ventilation port, causing the resonant plate 39 to vibrate during the flow. This vibration is transmitted through the resonant plate 39 to the retaining ring 34, causing the filter plate 35 to vibrate accordingly, shaking out debris stuck in the mesh of the filter plate 35, reducing the risk of clogging the filter plate 35 and ensuring the normal water storage and drainage process. At the same time, the elastic tube 36 is always pressed against the spoiler 27, helping to maintain its stability during its rotation and reducing deformation and displacement caused by water impacting the spoiler 27.
