Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering drainage, in particular to a leakage-proof drainage structure for civil engineering. Background Art
[0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It refers to the materials, equipment used, and the technical activities such as surveying, design, construction, maintenance, and repair carried out, as well as the objects of engineering construction. House leakage directly affects the quality of construction projects. In order to alleviate house leakage, it is necessary to drain the accumulated water through drainage devices.
[0003] The patent with announcement number CN220908626U discloses a house anti-leakage drainage device, including a drainage pipe, the top of which is fixedly connected to a water inlet head, the outer wall of which is fixedly connected to a mounting block, the outer wall of which is provided with a mounting hole, and the inner wall of which is fixedly connected to a fixing rod. The above device realizes the screening function, thereby reducing the situation where debris is easily blocked during drainage, and is conducive to automatic unblocking when blockage occurs.
[0004] The above-mentioned device utilizes the up and down movement of the movable screen plate to drive the dredging rod located below the movable screen plate to rotate in the water inlet head, so as to stir up the debris and loosen it so as to facilitate the flow of water. However, debris such as leaves are easily dropped on the house, and larger debris such as leaves are easily accumulated on the upper surface of the movable screen plate during rain, causing another blockage situation, which makes the device less practical. Utility Model Content
[0005] The purpose of this utility model is to provide a civil engineering anti-leakage drainage structure in order to solve the above problems, as described below.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] The utility model provides a civil engineering anti-leakage drainage structure, comprising an outer tube and an inner tube, wherein the outer wall of the upper end of the outer tube is provided with a mounting ring, the inner tube and the outer tube cooperate to form a debris outflow cavity, and a sealing cover for blocking the upper end of the debris outflow cavity is integrally formed between the upper end of the inner tube and the outer tube, a filter box is provided above the interior of the inner tube, and the filter box is integrally formed of two parts along its axial direction, the upper part being a frustum part and the lower part being a cylinder part, an elastic component for driving the filter box to move upward is provided in the inner tube, and the movable end of the elastic component is provided with a driving plate for contacting with the water flow, and a plurality of flow grooves are evenly opened on the upper part of the side wall of the inner tube.
[0008] By adopting the above-mentioned civil engineering anti-leakage drainage structure, when water flows, it flows out from the inner tube after passing through the filter box, and debris such as leaves are blocked on the inclined surface of the frustum. The water flow contacts the driving plate, driving the filter box to overcome the elastic force of the elastic component and move downward. At this time, the leaves move into the inner tube together with the frustum. When the large diameter end of the frustum is located at the flow groove, the leaves and other debris flow through the flow groove with the water into the debris outflow cavity and are discharged, avoiding blockage.
[0009] Preferably, a plurality of water filtering slots are evenly provided on the conical surface of the frustum portion, a filter screen is provided on the bottom surface of the cylindrical portion, and the diameter of the cylindrical portion is adapted to the aperture of the inner tube.
[0010] Preferably, the elastic component includes a horizontal plate fixedly connected to the inside of the inner tube, a sliding hole is opened through the middle of the horizontal plate, a sliding rod is slidably connected in the sliding hole, the bottom surface of the cylindrical part is detachably connected to the upper end of the sliding rod, the lower end of the sliding rod is fixedly connected to a circular plate, a spring is connected between the circular plate and the horizontal plate, and the spring is sleeved on the sliding rod.
[0011] Preferably, there are a plurality of driving plates, which are evenly fixedly connected to the circumferential surface of the circular plate.
[0012] Preferably, the elastic force of the spring is weaker than the impact force of the water flow.
[0013] Preferably, a threaded hole is provided in the middle of the bottom surface of the cylindrical portion, and the upper end of the sliding rod is threadably fitted into the threaded hole.
[0014] Preferably, a plurality of through holes are formed through the mounting ring.
[0015] The beneficial effects are:
[0016] After water flows through the filter box, it flows out from the inner tube. Leaves and other debris are blocked on the inclined surface of the frustum. The water flow contacts the driving plate, driving the filter box to overcome the elastic force of the elastic component and move downward. At this time, the leaves move into the inner tube together with the frustum. When the large diameter end of the frustum is located at the flow groove, leaves and other debris flow through the flow groove with the water and enter the debris outflow cavity for discharge, avoiding blockage and improving the drainage effect.

[0025] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-Figure 5 As shown, the utility model provides a civil engineering anti-leakage drainage structure, including an outer tube 1 and an inner tube 3, the outer wall of the upper end of the outer tube 1 is provided with a mounting ring 2, the inner tube 3 and the outer tube 1 cooperate to form a debris outflow cavity 5, and the upper end of the inner tube 3 and the outer tube 1 are integrally formed with a cover 4 for blocking the upper end of the debris outflow cavity 5, a filter box 6 is provided on the upper part of the inner tube 3, the filter box 6 is integrally formed by two parts along its axial direction, the upper part is a frustum part 62, and the lower part is a cylindrical part 61, an elastic component for driving the filter box 6 to move upward is provided in the inner tube 3, the movable end of the elastic component is provided with a driving plate 16 for contacting with the water flow, and a plurality of flow grooves 7 are evenly opened on the upper part of the side wall of the inner tube 3.
[0027] Furthermore, a number of water filter slots 9 are evenly opened on the conical surface of the frustum 62, a filter screen 10 is provided on the bottom surface of the cylindrical portion 61, and the diameter of the cylindrical portion 61 is adapted to the aperture of the inner tube 3, so that water can flow through the filtered water slots 9 into the cylindrical portion 61. At this time, large impurities are blocked on the outside of the inclined surface of the frustum 62, while small impurities are blocked on the surface of the filter screen 10. The cylindrical portion 61 is adapted to the aperture of the inner tube 3, which can prevent impurities from leaking from the gap between the two when the filter box 6 moves downward.
[0028] Reference Figure 3 As shown, the elastic component includes a transverse plate 11 fixedly connected to the inside of the inner tube 3, and a sliding hole 12 is opened through the middle of the transverse plate 11, and a sliding rod 13 is slidably connected to the sliding hole 12. The bottom surface of the cylindrical portion 61 is detachably connected to the upper end of the sliding rod 13, and the lower end of the sliding rod 13 is fixedly connected to a circular plate 14. A spring 15 is connected between the circular plate 14 and the transverse plate 11, and the spring 15 is sleeved on the sliding rod 13. When the water flow falls in the filter box 6, it contacts the driving plate 16, driving the circular plate 14, the sliding rod 13 and the filter box 6 to overcome the pulling force of the spring 15 and move downward. When there is no water flowing, the filter box 6 automatically moves up under the pulling force of the spring 15.
[0029] Specifically, there are several driving plates 16, which are evenly fixed on the circumferential surface of the circular plate 14. The elastic force of the spring 15 is weaker than the impact force of the water flow, so that the water flow can smoothly pass through the driving plates 16 under the action of impact force and gravity to drive the filter box 6 to move downward in the inner tube 3.
[0030] Reference Figure 5 As shown, a threaded hole 17 is provided in the middle of the bottom surface of the cylindrical portion 61, and the upper end of the slide rod 13 is threadedly adapted to the threaded hole 17. When a large number of small impurities are collected in the cylindrical portion 61 and blockage occurs, the filter box 6 can be removed and cleaned or replaced by rotating it.
[0031] Specifically, a plurality of through-holes 8 are formed through the mounting ring 2 , and the outer tube 1 can be mounted in the drainage trough through the through-holes 8 for use.
[0032] With the above structure, when water flows, it flows through the filter box 6 and then flows out of the inner tube 3. Leaves and other debris are blocked on the inclined surface of the frustum 62. Under the action of gravity, the water flow contacts the driving plate 16, driving the filter box 6 to overcome the elastic force of the elastic component and move downward. At this time, the leaves move into the inner tube 3 together with the frustum 62. When the large-diameter end of the frustum 62 is located at the flow groove 7, the leaves and other debris flow through the flow groove 7 with the water and enter the debris outflow chamber 5 for discharge, avoiding blockage.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
