Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to a leak-proof connection device for the inlet and outlet of a storage tank. Background Technology

[0002] There are many types of storage tanks, among which rainwater storage tanks are specialized equipment for collecting and storing rainwater. With the development of urbanization, water shortage and rainwater runoff pollution problems have become prominent, and the demand for rainwater recycling has increased, driving rainwater storage tanks to evolve from simple water storage ponds to specialized equipment. Functionally, they integrate systems such as filtration and liquid level control, adapting to different scenarios, relieving water supply pressure, reducing urban flooding, and becoming an important facility for water resource recycling and ecological protection.

[0003] The inlet and outlet of the rainwater storage tank are the core connection nodes between the tank and the pipeline, undertaking the key functions of rainwater transportation and circulation. Its sealing and structural integrity directly affect the operating efficiency of the storage tank.

[0004] During the long-term operation of rainwater storage tank connection devices, impurities carried by rainwater during collection tend to accumulate on the inner wall of the pipeline. Long-term accumulation can lead to a reduction in the pipeline's flow cross-section. When the blockage reaches a certain level, excessive pressure can damage the sealing of the connection, causing the sealing ring to age faster, the interface to loosen, and ultimately leading to leakage. To prevent pipeline blockage, the filter screen of the connection device needs to be manually disassembled and cleaned regularly. However, existing connection structures mostly use fixed flanges or welded connections. Disassembly requires loosening bolts one by one, which is cumbersome, time-consuming, and labor-intensive. Especially in confined installation spaces or complex pipeline layouts, the disassembly process can easily cause damage to surrounding components. Furthermore, repeated disassembly can reduce the stability of the connection structure, thus causing leakage. Therefore, a leak-proof connection device for the inlet and outlet of the storage tank is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof connection device for the inlet and outlet of a storage tank to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A leak-proof connection device for the inlet and outlet of a storage tank includes a storage tank and a pipe. The pipe is fixedly installed at the bottom of the storage tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, through the provision of a storage tank, pipes, and a pipe plug mechanism, during the drainage process, when the filter holes are blocked, the pipe plug mechanism is pulled during inspection, and the connecting rod will move the filter screen.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] Please see Figures 1-8 This utility model provides a technical solution:

[0034] A leak-proof connection device for the inlet and outlet of a storage tank includes a storage tank 1 and a pipe 2. The pipe 2 is fixedly installed at the bottom of the storage tank 1. A filter screen 3 is slidably connected to the inside of the pipe 2. A connecting rod 5 is installed inside the pipe 2 and passes through the filter screen 3. A rubber plug 6 is fixedly connected to one end of the connecting rod 5, and a pipe plug mechanism 4 is fixedly installed at the other end of the connecting rod 5. The pipe plug mechanism 4 includes a primary pipe plug 41. A rubber fixing groove seat 42 is fixedly connected to one end of the primary pipe plug 41, and a pipe plug base plate 46 is fixedly connected to the other end of the primary pipe plug 41. An inflatable rubber ring 43 is fixedly installed on the inner side of the seat 42. A handle 47 is fixedly installed on one side of the pipe plug base plate 46. A second main component 45 of the pipe plug is fixedly connected to the other side of the pipe plug base plate 46. A push plate 44 is fixedly connected to one side of the second main component 45 of the pipe plug. The second main component 45 of the pipe plug includes a second main body 451 of the pipe plug. An inflation valve 452 is fixedly connected to the inner side of the second main body 451 of the pipe plug. An air release groove 453 is opened on the inner side of the second main body 451 of the pipe plug. A spring top plate 454 is fixedly connected to one side of the second main body 451 of the pipe plug. A return spring 455 is fixedly connected to one end of the spring top plate 454.

[0035] As a further implementation of this scheme, the pipeline 2 includes a pipe body 21, a flow guide 22 is fixedly connected to the inner side of the pipe body 21, and a retaining ring 23 is fixedly installed on the inner side of the pipe body 21. The side of the retaining ring 23 near the push plate 44 is in close contact with the side of the push plate 44 near the retaining ring 23. The reason for the side of the retaining ring 23 near the push plate 44 in close contact with the side of the push plate 44 near the retaining ring 23 is that when the push plate 44 touches the retaining ring 23, the push plate 44 will not be able to pass through due to the retaining ring 23 being too small, thus preventing the push plate 44 from operating normally.

[0036] As a further implementation of this solution, the guide 22 is funnel-shaped and the rubber plug 6 is arc-shaped. The rubber plug 6 is adapted to the small diameter end opening of the guide 22. The rubber plug 6 is arc-shaped so that it can better block the small diameter end opening of the guide 22 when in use, which can effectively prevent rainwater from overflowing from the gap.

[0037] As a further implementation of this solution, the filter screen 3 includes a filter main component 31. A partition structure 32 is fixedly connected to one side of the filter main component 31, and a sealing rubber ring 34 is fixedly connected to one side of the partition structure 32. The sealing rubber ring 34 is fixedly connected to one side of the partition structure 32 to prevent rainwater from overflowing from the gaps, which would result in poor sealing effect of the sealing rubber ring 34.

[0038] As a further implementation of this solution, the filter main component 31 has a filter hole 33 on its inner side. The filter hole 33 is circular in shape, and the partition structure 32 is cross-shaped. The cross-shaped partition structure 32 can divide the internal space of the storage tank into multiple small areas, restrict the flow range of the liquid, and reduce the amplitude and impact of rainwater sloshing.

[0039] As a further implementation of this scheme, the second main component 45 of the pipe plug is slidably connected to the inner side of the first main component 41 of the pipe plug. The inner side of the inflatable rubber ring 43 is tightly attached to the outer side of the second main component 45 of the pipe plug. An inflation rubber port 48 is opened on the inner side of the inflatable rubber ring 43. The inner side of the inflatable rubber ring 43 is tightly attached to the outer side of the second main component 45 of the pipe plug to prevent gaps between the second main component 45 of the pipe plug and the inflatable rubber ring 43, which would allow rainwater to enter and affect the practicality of the device.

[0040] As a further implementation of this solution, the inflation valve 452 is adapted to the inflation rubber port 48, and the deflation groove 453 is opened in the shape of a cuboid. The reason for opening the deflation groove 453 in the shape of a cuboid is to prevent the gas from not being completely discharged due to insufficient space when the inflation rubber ring 4 is deflated, thus affecting the practicality of the inflation rubber ring 4.

[0041] Workflow: During use, pipe 2 is installed at the bottom of storage tank 1. The pipe plug mechanism 4 is inserted into the inside of pipe body 21. Push plate 44 first contacts retaining ring 23, and push plate 44 presses against pipe plug main component 45 to apply pressure to reset spring 455. Since the inflation rubber ring 43 is fixedly connected to pipe plug main component 41, and the inside of pipe plug main component 41 is slidably connected to the outside of pipe plug main component 45, when one side of pipe plug bottom plate 46 contacts one side of pipe body 21, the inflation valve 452 inside pipe plug main component 451 can just block the inflation rubber ring 43 to inflate. Due to the connection rod 5 at one end The connecting rod 5 is fixedly connected to the bottom plate 46 of the pipe plug. The connecting rod 5 passes through the partition structure 32 of the filter screen 3. The partition structure 32 is fixedly installed on one side of the filter main component 31. Several filter holes 33 are opened on the inner side of the filter main component 31. A sealing rubber ring 34 is fixedly connected to the outer side of the partition structure 32. During the movement, the sealing rubber ring 34 forms an arc when it touches the retaining ring 23, which can effectively prevent rainwater from entering from the outside of the filter screen 3. The other end of the connecting rod 5 is fixedly connected to the rubber plug 6. At the same time, the filter screen 3 is just in the center of the pipe 2, and the rubber plug 6 is at the top of one side of the pipe 2.

[0042] During use, pulling the handle 47 causes the return spring 455 to push the spring top plate 454 back, thereby causing the main body 451 of the pipe plug to move the inflation valve 452 forward. Since the opening direction of the venting groove 453 corresponds to the opening direction of the inflation rubber port 48, and the venting groove 453 is rectangular, the inflation rubber ring 43 is deflated during the movement. At the same time, the connecting rod 5 will drive the filter screen 3 and the rubber plug 6 to move. When the filter screen 3 is pulled out, the rubber plug 6 just blocks the smaller end of the guide 22 to prevent rainwater from continuing to flow out, thus achieving more convenient disassembly or installation.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
