Description

Technical Field

[0001] This utility model relates to the field of soft water cellar technology, specifically to a soft water cellar with a long-lasting leak-proof water intake structure. Background Technology

[0002] The existing soft water cellar mainly consists of a cellar body and a rain-receiving surface. The top of the cellar body has an opening, and the rain-receiving surface is connected to the edge of the cellar body and covers the opening. Together, they enclose a water storage cavity. Both the rain-receiving surface and the cellar body are made of high-molecular plastic materials.

[0003] The lower part of the cellar is provided with a water outlet, which includes a water outlet hole, a connector, a nut, a union connector, a guide pipe, and a water intake valve. The assembly structure is as follows: the head of the connector passes through the water outlet hole, and the periphery of the water outlet hole on the rain collection surface is clamped between the connector seat and the nut by the nut. At the same time, the contact parts between the periphery of the water outlet hole and the connector seat and the nut are bonded and sealed with glue to prevent leakage. One end of the union connector is threaded to the inside of the connector head, and the other end is fitted with a connecting pipe by adhesive. The other end of the connecting pipe is equipped with a water valve.

[0004] The above structure has the following technical defects: the sealing performance of the outlet depends on the adhesive bonding, and the adhesive is prone to viscosity decay after long-term use, resulting in sealing failure and leakage; since the cellar is buried underground, excavation is required for repair after leakage, making maintenance cumbersome; frequent leakage and maintenance will cause damage to the cellar structure, thereby shortening the overall service life of the soft water cellar.

[0012] This utility model has the following beneficial effects:

[0013] Long-lasting leak prevention: The water intake sleeve and the cellar body are made of the same material and fixed by high-frequency welding. Combined with fasteners, the water intake sleeve and the connecting pipe are squeezed to achieve a seal, completely abandoning the traditional glue bonding method and avoiding leakage problems caused by glue aging and failure.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Reference Figure 1-5 The embodiments provided by this utility model are as follows:

[0023] A flexible water cellar with a long-lasting leak-proof water intake structure is used for rainwater collection and storage. It consists of a cellar body 1 and a rain-receiving surface 2. An opening is opened at the top of the cellar body 1, and the rain-receiving surface 2 is connected to the edge of the cellar body 1 and covers the opening. The two together enclose a water storage cavity, and both are made of high-molecular composite materials. To address the issues of leakage and cumbersome maintenance associated with traditional water outlet sealing methods that rely on glue, a water intake structure 3 is installed on the lower side of the pit body 1. This structure includes a water outlet hole on the side of the pit body 1 and a water intake sleeve 31 connected to the water outlet hole. The water intake sleeve 31 and the pit body 1 are made of the same material, reducing compatibility issues when connecting different materials. The water intake sleeve 31 is fixed to the pit body 1 by high-frequency welding through an annular connecting surface 312, resulting in a tighter connection compared to traditional clamping, thus preventing leakage at the connection point. A connecting pipe 32 is inserted inside the water intake sleeve 31, and a water valve 33 is installed at the outer end of the connecting pipe 32 to control the water flow. A clamp 34 is fitted around the outer periphery of the water intake sleeve 31. By tightening the clamp 34, the inner wall of the water intake sleeve 31 is tightly fitted to the outer wall of the connecting pipe 32, achieving a seal without glue and avoiding the risk of glue aging and failure. During later maintenance, the connecting pipe 32 can be disassembled by loosening the clamp 34 without excavating the pit body 1, making the operation convenient.

[0024] The connecting pipe 32 has a short tapered section at its front end. This tapered structure guides the connecting pipe 32 to be quickly inserted into the water intake sleeve 31, improving assembly efficiency. The outer diameter of the main body connected to the tapered section matches the maximum inner diameter of the water intake sleeve 31 in its expanded state, ensuring that the water intake sleeve 31 and the connecting pipe 32 are fully fitted after the clamp 34 is tightened, resulting in a more reliable seal. The clamp 34, as a fastener, is easy to operate and can be quickly tightened and loosened. The inner side of the clamp 34 has anti-slip teeth that mesh with the outer surface of the water intake sleeve 31, preventing the clamp 34 from loosening during long-term use, ensuring a stable seal, and further extending the service life of the water intake structure 3.

[0025] The installation method is as follows:

[0026] 1. A water outlet is opened in the lower part of the cellar body 1. A water outlet sleeve 31, which is integrally formed with the water outlet sleeve body 311 and the annular connecting surface 312, is taken. The annular connecting surface 312 of the water outlet sleeve 31 is fixed to the cellar body 1 by high frequency welding to ensure that the water outlet sleeve 31 is connected to the water outlet.

[0027] 2. Take a connecting pipe 32 with a short tapered section at the front end, guide the connecting pipe 32 through the tapered section and insert it into the water intake sleeve 31, and install a water valve 33 at the outer end of the connecting pipe 32;

[0028] 3. Take the clamp 34 with anti-slip teeth on the inside as a fastener, put the clamp 34 on the outer circumference of the water intake sleeve 31, so that the anti-slip teeth on the inside of the clamp 34 engage with the outer surface of the water intake sleeve 31, tighten the clamp 34, so that the inner wall of the water intake sleeve 31 fits tightly with the outer wall of the connecting pipe 32, and complete the seal, thus realizing the installation of the water intake structure 3.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
