AI Technical Summary
The existing floor drain filter cover is prone to blockage when debris accumulates, resulting in water accumulation in the trench and difficulty in cleaning, and it is impossible to judge the location of debris in a timely manner.
A telescopic floor drain filter cover is designed, including counterweight rings, drain pipes, filter covers, filter cover handles, water sealing plates and sealing sleeve rings. By lifting the filter cover handle, debris is cleaned above the water-stabilized surface, combining the porous plate and limiting protrusions to prevent blockage, achieving convenient cleaning.
It improves the cleaning efficiency of the filter cover, reduces the difficulty of the operators' work, and prevents blockage of sewage pipes and gas spillage.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor drain filter covers, in particular to a telescopic floor drain filter cover. Background Art
[0002] In oil refining and chemical companies, various pumps are used. To prevent hazardous substances such as pump oil from spilling out and contaminating the environment, drainage trenches are installed around the pumps. Floor drains are installed in the trenches, leading to drainage pipes and ultimately to locations such as sewage pools. To prevent debris from entering the floor drains and clogging the drainage pipes, floor drains are generally equipped with filter covers to filter out debris, intercepting debris on the surface of the cover. Currently, the most common floor drain filter covers are bowl-shaped. When drains are used, debris gradually accumulates on the surface of the cover. If not cleaned promptly, the drain will become blocked and eventually cause water to accumulate in the drain. The covered debris and turbid water make it difficult to clearly determine the position of the drain cover, making it difficult to properly clean the debris on the cover. Utility Model Content
[0003] The purpose of the utility model is to provide a telescopic floor drain filter cover.
[0004] The utility model provides the following technical solutions:
[0005] The utility model proposes a telescopic floor drain filter cover, which comprises a weight ring for being placed on the outlet of a sewage pipe, a drainage pipe passing through the weight ring, and a filter cover for preventing debris from entering the sewage pipe. The drainage pipe is arranged under the filter cover, and a filter cover handle is fixed on the filter cover.
[0006] Furthermore, a steel plate is provided at the end of the drain pipe to seal the end of the drain pipe. An opening is provided on the side wall of the drain pipe near the end. A water seal baffle is fixed to the upper end of the opening. The water seal baffle and the pipe wall at the upper end of the opening have an inclination angle of 130°-140°. The end of the water seal baffle extends downward and exceeds the lower end of the opening.
[0007] Furthermore, it also includes a sealing ring, which is sleeved on the drain pipe.
[0008] Furthermore, the filter screen of the filter cover is a porous plate, the pore size of the porous plate is 6 mm, and the center distance between adjacent holes is 8 mm.
[0009] Furthermore, a limiting protrusion is provided on the peripheral side of the end of the drain pipe.
[0010] Furthermore, the limiting protrusion is the weld between the steel plate and the end of the drain pipe.
[0011] Compared with the existing technology, when water accumulates in the ditch, the filter cover handle of the utility model can be lifted by hand, and the filter cover can be lifted above the surface of the accumulated water to clean up the debris. After cleaning, the filter cover can be put down. The utility model improves the cleaning efficiency of the filter cover, reduces the cleaning difficulty, and reduces the work difficulty of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] See Figure 1 and Figure 2 In one embodiment of the utility model, a telescopic floor drain filter cover includes a counterweight ring 1 for being placed on the outlet of a sewage pipe, a drain pipe 2 passing through the counterweight ring 1, and a filter cover 3 for preventing debris from entering the sewage pipe 00. The drain pipe 2 is arranged under the filter cover 3, and a filter cover handle 4 is fixed on the filter cover 3. When water accumulates in the ditch, the filter cover handle 4 can be lifted by hand, and the filter cover 3 can be lifted above the surface of the accumulated water to clean up the debris. After cleaning, the filter cover can be put down.
[0020] See Figure 1 and Figure 3In one embodiment of the present utility model, a steel plate 5 is provided at the end of the drain pipe 2 to seal the end of the drain pipe 2. An opening 6 is provided on the side wall of the drain pipe 2 near the end. A water seal baffle 7 is fixed to the upper end of the opening 6. The water seal baffle 7 and the pipe wall at the upper end of the opening 6 form an inclination angle a of 130°-140°. The end of the water seal baffle 7 extends downward and exceeds the lower end of the opening 6; so that the water seal baffle 7 will not affect the sewage from reaching the end of the drain pipe 2 and flowing out from the opening; at the same time, the sewage enters the end of the drain pipe 2 to form a water seal, thereby preventing the gas in the sewage pipe 00 from overflowing.
[0021] See Figure 1 and Figure 2 In one embodiment of the present invention, a sealing ring 8 is further included, which is arranged on the drain pipe 2; it prevents debris from continuously entering the sewage pipe 00 through the gap between the counterweight ring 1 and the drain pipe 2, causing blockage of the sewage pipe; and at the same time prevents the gas in the sewage pipe 00 from overflowing.
[0022] See Figure 1 In one embodiment of the present invention, the filter screen of the filter cover 3 is a porous plate with a pore size of 6 mm and a center distance of adjacent holes of 8 mm; this facilitates sewage to enter the drain pipe 2 while ensuring that weeds and other debris with larger particle sizes or lengths do not enter the drain pipe and cause blockage.
[0023] See Figure 1 and Figure 2 In one embodiment of the present invention, a limiting protrusion 9 is provided on the peripheral side of the end of the drain pipe 2 to prevent the drain pipe 2 from falling out of the sewage pipe 00 due to excessive upward pulling of the filter cover handle 4.
[0024] See Figure 4 and Figure 5 In the above embodiment, the limiting protrusion is the weld between the steel plate 5 and the end of the drain pipe 2; the outer diameter d1 of the weld is larger than the inner diameter d2 of the counterweight ring.
[0025] In actual application, when water accumulates in the ditch, the filter cover handle 4 can be lifted by hand, and the filter cover 3 can be lifted above the surface of the accumulated water to clean up the debris. After cleaning, the filter cover can be put down.
[0026] The implementation methods of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
