Technical Field

[0001] The utility model relates to the technical field of overflow pipes, in particular to an anti-blocking overflow pipe. Background Art

[0002] An overflow pipe is a pipe or device used to control liquid overflow. It is usually designed to direct excess liquid to another location when the liquid reaches a certain height or pressure to prevent the liquid from overflowing or causing damage. The design and function of the overflow pipe may vary in different application scenarios.

[0003] The existing overflow pipe has no filtering, sealing and other structures, which causes impurities in the water or dust and debris from the outside to enter the overflow pipe, thereby causing the overflow pipe to be blocked. Therefore, an anti-blocking overflow pipe is proposed. The inlet and outlet water can be filtered by setting a filter net 2, and the overflow pipe is sealed by a cover plate to prevent impurities in the water, external debris, etc. from entering the overflow pipe. Utility Model Content

The inlet and outlet water can be filtered by setting a second filter net, and the overflow pipe is sealed by a cover plate to prevent impurities in the water and external debris from entering the overflow pipe.

[0005] The technical solution adopted by the utility model to solve the technical problem is an anti-blocking overflow pipe, comprising an overflow pipe, a limiting ring is fixed at the top of the overflow pipe by bolts, a connecting rod is sleeved through the inside of the limiting ring, a floating assembly is arranged at the bottom end of the connecting rod located inside the overflow pipe, and a cover plate is arranged at the top end of the connecting rod located at the top of the limiting ring;

[0006] A liquid outlet pipe is welded at one end of the overflow pipe, a first filter screen is fixed inside the liquid outlet pipe through a slot, an externally threaded butt pipe is welded at the bottom end of the overflow pipe, and a second filter screen is fixed between the externally threaded butt pipe and the overflow pipe through bolts.

[0007] By adopting the above technical solution, the second filter screen filters the incoming water, the first filter screen filters in the liquid outlet pipe, and the cover plate seals the top of the overflow pipe to prevent impurities and debris from entering the overflow pipe and causing it to be blocked.

[0008] Specifically, the floating assembly includes a protective cover fixed to the bottom end of the connecting rod through a flange, and a floating block is glued inside the protective cover.

[0009] Specifically, the floating block is made of polyethylene material, and a rubber pad is glued to the bottom end of the floating block located at the bottom of the protective cover.

[0010] Specifically, a through hole is formed inside the limiting ring, and the connecting rod passes through the through hole.

[0011] Specifically, the limiting ring is located outside the through hole and has reserved grooves equidistantly extending therethrough.

[0012] Specifically, slots are provided on both sides of the overflow pipe.

[0013] Beneficial effects of the utility model:

[0014] (1) The utility model discloses an anti-blocking overflow pipe, wherein the second filter screen can filter the liquid entering the overflow pipe from the external threaded butt pipe to prevent impurities in the liquid from entering the overflow pipe, and the first filter screen can filter the liquid in the liquid outlet pipe to prevent impurities from entering the overflow pipe through the liquid outlet pipe. The cover plate is covered on the top of the overflow pipe to prevent foreign matter from entering the overflow pipe and avoid clogging of the overflow pipe.

[0015] (2) The utility model discloses an anti-blocking overflow pipe.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The filter screen 2 can filter the inlet and outlet water, and the overflow pipe can be sealed by the cover plate to prevent impurities in the water and foreign debris from entering the overflow pipe. Figure 1-4 As shown, the anti-blocking overflow pipe of the utility model comprises an overflow pipe 1, a limiting ring 2 is fixed at the top of the overflow pipe 1 by bolts, a connecting rod 3 is sleeved through the inside of the limiting ring 2, a floating assembly 4 is arranged at the bottom end of the connecting rod 3 located inside the overflow pipe 1, and a cover plate 5 is arranged at the top end of the connecting rod 3 located at the top of the limiting ring 2;

[0024] A liquid outlet pipe 6 is welded at one end of the overflow pipe 1, a first filter screen 7 is fixed inside the liquid outlet pipe 6 through a slot, an externally threaded butt pipe 9 is welded at the bottom end of the overflow pipe 1, and a second filter screen 10 is fixed between the externally threaded butt pipe 9 and the overflow pipe 1 by bolts.

[0025] When in use, the second filter screen 10 filters the incoming water, the first filter screen 7 filters in the liquid outlet pipe 6, and the cover plate 5 seals the top of the overflow pipe 1 to prevent impurities and debris from entering the overflow pipe 1 and causing blockage.

[0026] For example, Figure 3 As shown, the utility model also includes that the floating assembly 4 includes a protective cover 401 fixed to the bottom end of the connecting rod 3 through a flange, and a floating block 402 is glued inside the protective cover 401.

[0027] When in use, the protective cover 401 is used to protect the floating block 402 to prevent it from being worn.

[0028] For example, Figure 3 As shown, the utility model also includes that the floating block 402 is made of polyethylene material, and a rubber pad 403 is glued to the bottom end of the floating block 402 located at the bottom of the protective cover 401.

[0029] When in use, the rubber pad 403 can improve the sealing between the float 402 and the overflow pipe 1 .

[0030] For example, Figure 4 As shown, the utility model further includes that a through hole 201 is formed inside the limiting ring 2 , and the connecting rod 3 passes through the through hole 201 .

[0031] When in use, the connecting rod 3 opening the through hole 201 moves up and down.

[0032] For example, Figure 4 As shown, the utility model also includes that the inner part of the limit ring 2 located outside the through hole 201 is equidistantly penetrated with reserved grooves 202 .

[0033] When in use, the reserved groove 202 is opened so that the gas in the overflow pipe 1 can be discharged.

[0035] When in use, the opening of the card slot 8 makes it convenient for personnel to use tools to rotate the overflow pipe 1.

[0036] When the utility model is used, a person installs the overflow pipe 1 on a pipeline or water storage equipment through the external threaded butt pipe 9, and the opening of the clamping groove 8 facilitates the person to use a tool to rotate the overflow pipe 1;

[0037] The liquid in the pipeline or water storage equipment enters the overflow pipe 1 through the external threaded butt pipe 9, pushing the float 402 upward, so that the liquid squeezed into the overflow pipe 1 can flow out of the liquid outlet pipe 6, achieving the purpose of overflow;

[0038] The second filter screen 10 can filter the liquid entering the overflow pipe 1 from the external threaded butt joint 9 to prevent impurities in the liquid from entering the overflow pipe 1. The first filter screen 7 can filter the liquid in the liquid outlet pipe 6 to prevent impurities from entering the overflow pipe 1 through the liquid outlet pipe 6.

[0039] After the liquid in the overflow pipe 1 flows out through the liquid outlet pipe 6, the floating block 402 moves downward due to its own weight to block the external threaded butt joint pipe 9, and the cover plate 5 at the top of the connecting rod 3 covers the top of the overflow pipe 1, which can prevent foreign debris from entering the overflow pipe 1 and avoid clogging the overflow pipe 1.

[0040] The protective cover 401 can protect the floating block 402 from being easily worn. The setting of the rubber pad 403 can improve the sealing between the floating block 402 and the overflow pipe 1. The opening of the reserved groove 202 allows the floating block 402 to move up and down so that the gas in the overflow pipe 1 can be discharged.
