Description

Technical Field

[0001] The present application relates to the field of pumps, and in particular to a mesh cover for a pump. Background Art

[0002] The existing mesh cover has a consistent overall thickness. During the operation of the pump, it is inevitable that foreign matter will clog the water holes on the mesh cover. After the foreign matter is clogged, the flow rate of the water holes will become smaller, but since the suction force of the pump is still very large, the mesh cover will be sucked flat and collapsed due to insufficient strength. Utility Model Content

[0003] The present application provides a mesh cover for a pump, which can increase the strength of the mesh cover and ensure that the water inlet flow rate of the mesh cover is large enough.

[0004] The technical solution of this application is:

[0005] The present application provides a mesh cover for a pump, the mesh cover is arranged at the water inlet position of the pump, and the mesh cover comprises: a mesh cover body and a water inlet joint connected to the mesh cover body;

[0006] The mesh cover body is provided with a first circle of water-permeable holes and a second circle of water-permeable holes arranged around the circumference thereof, and the hole spacing of the first circle of water-permeable holes is smaller than the hole spacing of the second circle of water-permeable holes;

[0007] A plurality of reinforcing ribs are arranged circumferentially on the outer wall of the mesh cover body;

[0008] The number of reinforcing rib circles spanning the first circle of water-permeable holes is greater than the number of reinforcing rib circles spanning the second circle of water-permeable holes.

[0009] Preferably, the opening widths of the water-permeable holes in the first circle and the water-permeable holes in the second circle are the same.

[0010] Preferably, after the water inlet joint is connected to the water inlet joint of the pump, the mesh cover body is arranged obliquely in the water.

[0011] Preferably, the outer diameter of the mesh cover body gradually decreases from one side close to the water inlet joint to the other side far from the water inlet joint.

[0012] Preferably, the mesh cover body is threadedly connected to the water inlet joint.

[0013] Preferably, the mesh cover is a plastic part.

[0014] Since the hole spacing of the first circle of water-permeable holes is smaller than that of the second circle of water-permeable holes, it means that the number of the first circle of water-permeable holes will be more than that of the second circle of water-permeable holes. In order to ensure the overall strength of the mesh body, the number of reinforcing ribs across the first circle of water-permeable holes is greater than that of the second circle of water-permeable holes; the number of holes in the relatively larger barrel diameter of the mesh body (corresponding to the number of holes in the first circle of water-permeable holes) is set higher than the number of holes in the other part with a relatively smaller hole diameter (corresponding to the number of holes in the second circle of water-permeable holes) to ensure that the water inflow of the mesh body is large enough and has good strength. The mesh body is arranged obliquely in the water, so that after the pump sucks water, the residual water level in the mesh body is relatively low, which can enhance the pumping effect.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] A mesh cover 1 for a pump is provided in an embodiment of the present application, wherein the mesh cover 1 is arranged at the water inlet position of the pump, and the mesh cover 1 comprises: a mesh cover body 11 and a water inlet joint 12 connected to the mesh cover body 11; the mesh cover body 11 is provided with a first circle of water-permeable holes 111 and a second circle of water-permeable holes 112 arranged around the circumference thereof, and the hole spacing of the first circle of water-permeable holes 111 is smaller than the hole spacing of the second circle of water-permeable holes 112; a plurality of circles of reinforcing ribs 113 are arranged circumferentially on the outer wall of the mesh cover body 11; the number of circles of reinforcing ribs 113 bridging the first circle of water-permeable holes 111 is greater than the number of circles of reinforcing ribs 113 bridging the second circle of water-permeable holes 112.

[0020] like Figures 1 to 3As shown, the outer diameter of the mesh cover body 11 gradually decreases from one side close to the water inlet joint 12 to the other side away from the water inlet joint 12, that is, the mesh cover body 11 in the embodiment of the present application is designed as a trapezoidal barrel or a triangular barrel, the barrel bottom of the mesh cover body 11 is closed, and the top opening of the mesh cover body 11 is blocked by the water inlet joint 12. Impurities in the water are filtered out by the cylinder wall of the mesh cover body 11, and the water enters the mesh cover body 11 through the water-permeable holes on the cylinder wall of the mesh cover body 11, and then reaches the water inlet joint of the pump through the water inlet joint 12.

[0021] The first circle of water holes 111 is close to the water inlet side, and the second circle of water holes 112 is close to the bottom 114 of the mesh body 11. The opening widths of the first circle of water holes 111 and the second circle of water holes 112 are the same.

[0022] Since the hole spacing of the first circle of water-permeable holes 111 is smaller than the hole spacing of the second circle of water-permeable holes 112, it means that the number of the first circle of water-permeable holes 111 will be greater than the number of the second circle of water-permeable holes 112. In order to ensure the overall strength of the mesh cover body 11, the number of reinforcing ribs 113 bridged on the first circle of water-permeable holes 111 is greater than the number of reinforcing ribs 113 bridged on the second circle of water-permeable holes 112.

[0023] Those skilled in the art should understand that increasing the number of reinforcing ribs 113 will further improve the strength of the mesh cover body 11, but too many reinforcing ribs 113 will affect the water flow rate of the mesh cover body 11. For this reason, the embodiment of the present application combines the actual structural design of the mesh cover body 11, and sets the number of holes in the relatively larger barrel diameter of the mesh cover body 11 (corresponding to the number of water-permeable holes 111 in the first circle) to be greater than the number of holes in the relatively smaller diameter (corresponding to the number of water-permeable holes 112 in the second circle), so as to ensure that the water flow rate of the mesh cover body 11 is large enough and has good strength.

[0024] In addition, in the embodiment of the present application, after the water inlet connector 12 is connected to the water inlet connector 12 of the pump, the mesh cover body 11 is arranged obliquely in the water. The mesh cover body 11 is arranged obliquely in the water, so that after the pump sucks water, the residual water level in the mesh cover body 11 is relatively low, which can enhance the suction effect of the pump.

[0025] In the embodiment of the present application, the mesh cover body 11 is threadedly connected to the water inlet joint 12 and is sealed by a sealing ring, which is easy to assemble and has good sealing performance.

[0026] In the embodiment of the present application, the mesh cover 1 is a plastic part, and the product cost is low.

[0027] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0028] Although the preferred embodiments of the utility model embodiments have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the utility model embodiments.

[0029] It should also be noted that, in this article, the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, relational terms such as "first" and "second" are used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations, nor can they be understood as indicating or implying relative importance. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or terminal device including a series of elements does not include those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of more restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.

[0030] The technical solution provided by the utility model is described in detail above. The principle and implementation method of the utility model are described in this article using specific examples. The description of the above embodiments is only used to help understand the utility model, and the content of this specification should not be understood as limiting the utility model. At the same time, for those skilled in the art, according to the utility model, there will be different forms of changes in the specific implementation methods and application scopes. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived from them are still within the protection scope of the utility model.
