[0002] In many cases, construction sites need to use water pumps to extract surface water or water from deep pits. Due to the particularity of construction sites, the water contains a large amount of large and small debris. These debris will enter the water pump with the water flow, causing the water pump to be blocked and damaged, affecting the normal operation of the water pump. Utility Model Content

[0010] The top frame and the bottom frame are opposite to each other and connected by three or more vertical rods;

[0011] The bearing plate is fixedly connected to the bottom frame;

[0012] The filter mesh is connected to the vertical rod.

[0013] Furthermore, the filter mesh is detachably connected to the vertical rod.

[0014] Furthermore, two or more parallel cards are respectively provided on the opposite surfaces of each of two adjacent vertical rods; card slots are formed between adjacent cards, and the card slots are through slots with their lengths along the vertical direction;

[0017] Furthermore, a rubber strip is provided around the outer periphery of the mesh fixing frame.

[0018] Furthermore, when there are more than two slots on each vertical rod, more than two filter meshes can be arranged in sequence from the outside to the inside, and the area of ​​a single hole of the filter mesh of the filter mesh decreases in sequence from the outside to the inside.

[0020] Beneficial effects:

[0021] (1) The utility model provides a water pumping filter basket. When the water pump is pumping water, the filter mesh of the filter basket isolates the debris in the water from the water pump, thereby solving the problem of clogging the water pump when using the water pump to pump water in water with debris, and improving the water pumping efficiency of the water pump.

[0022] (2) The filter mesh of the utility model is detachably connected to the vertical rod, which is convenient for replacing the filter mesh. On the one hand, the filter mesh can be replaced in time when it is congested; on the other hand, the filter mesh can be replaced with different mesh sizes according to the size of the debris, thereby improving the water pumping efficiency.

The single hole area of ​​the filter mesh of the filter mesh decreases from the outside to the inside. The larger holes on the outside filter large debris, and the smaller holes on the inside filter small debris. Large debris and small debris can be intercepted by classification, which can increase the flow rate of water entering the filter basket and improve the pumping efficiency of the water pump.

[0039] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0040] Example 1:

[0041] This embodiment provides a water pump water filter basket, see attached Figure 1 , including a fixing frame 2 and a filter mesh 1; the fixing frame 2 is a frame structure, and a bearing plate 9 is provided at the bottom of the fixing frame 2; the filter mesh 1 is arranged around the side wall surface of the fixing frame 2; when pumping water, the filter basket is placed in the water, and the top surface of the filter basket is higher than the water surface 18; the water pump 16 is located on the bearing plate 9 in the frame structure.

[0042] The pumping filter basket provided in this embodiment has a filter mesh 1 that isolates debris in the water from the water pump 16 when the water pump 16 is pumping water, thereby solving the problem of clogging the water pump 16 when pumping water in water with debris, and improving the pumping efficiency of the water pump 16.

[0043] See attached Figure 2-4 , the fixing frame 2 also includes a top frame 4, a vertical rod 5 and a bottom frame 8;

[0044] The top frame 4 and the bottom frame 8 are opposite to each other and connected by three or more vertical rods 5; the bearing plate 9 is fixedly connected to the bottom frame 8; the filter mesh 1 is fixedly connected or detachably connected to the vertical rods 5;

[0045] In one embodiment, one or more hanging rings 3 are provided on the top of the fixing frame 2 to facilitate hanging the filter basket in water via a hanging rope 19 for use in different water depths.

[0046] In one embodiment, see the attached Figure 4 and 5 , the opposite surfaces of each two adjacent vertical rods 5 are respectively provided with two or more parallel cards 6; a card slot 10 is formed between adjacent cards 6, and the card slot 10 is a through slot with a length along the vertical direction;

[0047] See attached Figure 6-8 The filter mesh 1 includes a filter mesh and a mesh fixing frame 11, and the filter mesh is fixedly arranged in the mesh fixing frame 11;

[0048] The mesh fixing frame 11 can be inserted into the opposite slots 10 of two adjacent vertical rods 5 along the vertical direction, so that the filter mesh 1 and the vertical rods 5 are detachably connected; thereby, the filter mesh 1 can be replaced.

[0049] Furthermore, a rubber strip 12 is provided around the outer periphery of the mesh fixing frame 11 to achieve sealing between the filter mesh 1 and the fixing frame 2 .

[0050] Furthermore, when there are more than two slots 10 on each vertical rod 5, more than two filter meshes 1 can be arranged sequentially from the outside to the inside, with the individual pore areas of the filter meshes of the filter meshes 1 decreasing from the outside to the inside. The larger pores on the outside filter large debris, while the smaller pores on the inside filter small debris, thereby separating and intercepting large and small debris. This increases the flow rate of water entering the filter basket and improves the pumping efficiency of the water pump 16.

[0051] Working principle:

[0052] See attached Figure 9 The water pump pumps water to the filter basket and connects it to the hanging ring 3 through a lifting rope 19. The filter basket is hoisted and placed in the water, and the top frame 4 of the water pump pumps water to the filter basket is located above the water surface 18. The water pump 16 is located in the filter basket and on the supporting plate 9. The filter mesh 1 of the filter basket isolates the debris in the water outside the filter basket. The water pump pumps the water in the filter basket and discharges it through the water pump drain pipe 17, thereby solving the problem of clogging the water pump 16 when using the water pump to pump water in water with debris, and improving the pumping efficiency of the water pump 16.

[0053] When there are only large or small debris in the water, it is only necessary to install the corresponding filter mesh 1 on the fixing frame 2 to perform the water pumping operation.

[0054] When there are both large and small debris in the water, two or more filter meshes 1 can be arranged in sequence from the outside to the inside, with the pore area of ​​the filter mesh of the filter mesh 1 decreasing from the outside to the inside. The larger pores on the outside filter large debris, while the smaller pores on the inside filter small debris, which can be separated and intercepted. This can increase the flow rate of water entering the filter basket and improve the pumping efficiency of the water pump 16.

[0058] The opposite surfaces of each two adjacent vertical rods 5 are respectively provided with three cards 6, forming two card slots 10, which can accommodate up to two filter meshes 1 at a time;

[0059] See attached Figure 6 、 10 and 11, there are three types of filter mesh 1 to choose from, namely filter mesh I, filter mesh II and filter mesh III;

[0060] The filter mesh of filter sheet I is a large-size filter mesh 13, the filter mesh of filter sheet II is a medium-size filter mesh 14, and the filter mesh of filter sheet III is a small-size filter mesh 15; among them, the hole area of ​​each hole on the large-size filter mesh 13 is greater than the hole area of ​​each hole on the medium-size filter mesh 14, and the hole area of ​​each hole on the small-size filter mesh 15.
