[0034] In order to further explain the technical means and effects adopted by the utility model for realizing the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0035] Please refer to Figures 1-12The embodiment aims to provide a groundwater guiding and discharging device, which comprises a water storage tank 1 arranged on the ground, a water pumping pipe 3 fixed at the center of the water storage tank 1, and a plurality of water filtering pipes 2 arranged on the water storage tank 1 in an inclined manner, wherein each water filtering pipe 2 comprises an outer cylinder 21 and an inner cylinder 22, the inner cylinder 22 is rotatably arranged in the outer cylinder 21, a plurality of sealing blocks 213 for preventing blockage are arranged on the outer cylinder 21 in an annular array, and the outer wall of the inner cylinder 22 is fixedly provided with a plurality of fixed blocks 221 with different hole diameters in an annular array, and the surface of the fixed blocks 221 is arc-shaped.

[0036] An annular groove 211 is formed in the outer cylinder 21, and the inner cylinder 22 is rotatably arranged in the annular groove 211.

[0037] A plurality of limiting grooves 212 are formed through the side wall of the outer cylinder 21, and the sealing blocks 213 are slidably arranged in the limiting grooves 212, and the limiting grooves 212 are communicated with the annular groove 211.

[0038] One end of the sealing block 213 is arc-shaped, and in the process of collecting water, the arc-shaped end of the sealing block 213 is attached to the center of the arc-shaped end of the fixed block 221.

[0039] The sealing block 213 is fixedly provided with a spring 214 at both ends, and the other end of the spring 214 is fixedly connected with the sealing block 213, a column groove adapted to the spring 214 is formed in the side wall of the sealing block 213, one end of the spring 214 is fixed in the column groove, and the other end is fixedly connected with the outer wall of the sealing block 213. The main function of the spring 214 is to provide elastic force, so that the sealing block 213 can keep a stable position in the limiting groove 212.

[0040] In the initial state, the sealing block 213 completely enters the limiting groove 212, and the arc-shaped end thereof is tightly attached to the side wall of the inner cylinder 22, so as to ensure that the inlet of the water filtering pipe 2 is closed when no external force is applied, thereby preventing the unfiltered inflow of groundwater, and meanwhile, the arc-shaped end of the sealing block 213 is located between the two adjacent groups of fixed blocks 221.

[0041] A recess 2132 is formed at the center of the sealing block 213, and a water inlet groove 2131 is formed at both ends of the sealing block 213, and the water inlet groove 2131 is communicated with the recess 2132.

[0042] When it is necessary to collect groundwater using the filter pipe 2, the inner cylinder 22 will be rotated. During the rotation, the fixed block 221 will gradually come into contact with the arc-shaped end of the sealing block 213, and as the inner cylinder 22 continues to rotate, the fixed block 221 will gradually push the sealing block 213 outward. During this process, the sealing block 213 will slide in the limiting groove 212, and the water inlet groove 2131 thereon will gradually be exposed. When the groundwater flows into the recess 2132 through the water inlet groove 2131, it will be temporarily stored in this space. As the inner cylinder 22 further rotates, the through hole 2211 on the fixed block 221 will gradually align with the recess 2132, as shown in Figs. 10 and 11. At this time, the groundwater in the recess 2132 will flow into the interior of the filter pipe 2 through the through hole 2211, and eventually reach the water storage tank 1. Figure 8 、 Figure 9

[0043] During the process of the sealing block 213 being pushed out, it will also push the surrounding soil away. This pushing effect can effectively prevent soil particles from blocking the water inlet groove 2131 and the through hole 2211, thereby ensuring the long-term stable operation of the filter pipe 2.

[0044] Furthermore, the inner cylinder 22 is provided with two groups of fixed blocks 221 with different diameters of the through hole 2211. According to the permeability and particle size of the underground soil, the fixed block 221 with the appropriate diameter of the through hole 2211 is selected to push out the sealing block 213. For soil with good permeability and small particles, a smaller diameter of the through hole 2211 can be selected to ensure that only fine water flow can pass through, while preventing larger soil particles from entering the filter pipe 2. For soil with poor permeability and large particles, a larger diameter of the through hole 2211 is required to allow more water flow to pass through while maintaining a certain filtering effect.

[0045] The inner cylinder 22 is provided with a plurality of screw holes 222 distributed along the circumferential direction of the inner cylinder 22. Screws are screwed into the screw holes 222. After the rotation of the inner cylinder 22 is completed, the position of the inner cylinder 22 is fixed by the screws.

[0046] ​The design of the screw hole 222 is not only used for installing screws to fix the position of the inner cylinder 22, but also used to provide visual indication of the relative rotation of the inner cylinder 22 and the outer cylinder 21. Since three screw holes 222 are provided, when the left screw hole 222 of the inner cylinder 22 is aligned with the hole on the outer cylinder 21, the center of the large-diameter through hole 2211 fits with the center of the sealing block 213, which means that the water filter pipe 2 will allow more water flow through, suitable for soil conditions with good permeability and large particles; when the middle screw hole 222 of the inner cylinder 22 is aligned with the hole on the outer cylinder 21, the center of the small-diameter through hole 2211 fits with the center of the sealing block 213, which is suitable for soil conditions with poor permeability and small particles, to ensure that only fine water flow can pass through, while preventing larger soil particles from entering the water filter pipe 2; when the right screw hole 222 of the inner cylinder 22 is aligned with the hole on the outer cylinder 21, the center of the sealing block 213 fits with the side wall of the inner cylinder 22 and is located between the two adjacent groups of fixing blocks 221, which means that the inlet of the water filter pipe 2 is closed and underground water cannot flow in. After adjustment, the position of the inner cylinder 22 can be fixed by tightening the screws to prevent accidental rotation.

[0047] Through holes 2211 are provided through the fixing blocks 221 and the inner cylinder 22, and the diameter of the through holes 2211 is smaller than the diameter of the grooves 2132. The smaller diameter of the through holes 2211 can more effectively filter out larger soil particles and impurities. The water filter pipe 2 is inclinedly arranged on the water storage tank 1, which helps the underground water to flow more smoothly into the inside of the water filter pipe 2 under the action of gravity, reduces the resistance of the water flow at the inlet of the water filter pipe 2, and enables more water flow to be effectively filtered and collected. In the case of high underground water level or heavy rainfall, the inclinedly arranged water filter pipe 2 can quickly discharge underground water to prevent the water storage tank 1 from being overfilled or overflowing.

[0048] A water pump 4 is arranged at the bottom of the water storage tank 1, which is in communication with the water suction pipe 3. The water pump 4 is used to control the discharge of water in the water storage tank 1, facilitating the guidance and management of underground water.

[0049] The outer wall of the water storage tank 1 is coated with a thermal insulation coating, which is used to maintain the stability of the internal water temperature of the water storage tank 1. The material of the thermal insulation coating is preferably polyurethane foam, which has excellent thermal insulation performance. Coating the thermal insulation coating can effectively reduce the fluctuation of the internal water temperature of the water storage tank 1 caused by the influence of the external environment, especially in cold seasons, which can avoid the problem of water pipe freezing caused by too low water temperature, and ensure the continuous and stable operation of the underground water guiding and discharging device.

[0050] The utility model discloses in specific use, first, the water storage tank 1 is buried in the predetermined underground position, and the upper end portion of filter pipe 2 should be exposed above ground, according to the permeability and particle size of underground soil, select suitable fixed block 221, manually rotate inner tube 22, make its fixed block 221 gradually contact with sealing block 213, along with the rotation of inner tube 22, fixed block 221 will push sealing block 213 outwards, sealing block 213 will slide in the limiting groove 212 simultaneously, and gradually expose the water inlet groove 2131, until the through hole 2211 on the fixed block 221 of required is aligned with the recess 2132 on sealing block 213, then install screw in screw hole 222 to fix inner tube 22, bury the exposed portion of filter pipe 2 to the underground, ensure that filter pipe 2 is in close contact with soil, when groundwater passes through filter pipe 2 and enters water storage tank 1, start water pump 4, and the water in water storage tank 1 is drawn out through water suction pipe 3.

[0051] The above, only the preferred embodiment of the utility model has been, and does not make any form to the utility model limit, although the utility model has disclosed as above with preferred embodiment, however not to define the utility model, any person skilled in the art, when can utilize the technical content disclosed above make a little more change or modification is equivalent variation equivalent embodiment, but whatever does not leave the utility model technical scheme content, according to the technical essence of the utility model to the above embodiment of any brief introduction modification, equivalent variation and modification, still belong to the range of the utility model technical scheme.
