Description
Technical Field
[0001] This utility model belongs to the field of submersible pump technology, specifically relating to a water pump that is clogging-resistant and easy to clean. Background Technology
[0002] As a key piece of equipment for water transport and circulation, the performance and stability of submersible pumps directly affect the operating efficiency and maintenance costs of the entire water system. Traditional submersible pumps, when treating water containing impurities or particulate matter, mostly rely on pre-filter housings to remove impurities through physical interception. The filter housing has a cover structure and is connected to the pump body via elastic clips. However, the following problems may arise during long-term use:
[0003] 1. After the filter housing becomes clogged, the operator needs to remove the filter housing from the water pump body for cleaning and then reinstall it on the water pump body, or lift the water pump body out of the water for cleaning. This cleaning method will cause the plastic clips to break quickly due to repeated deformation, making it impossible to assemble and connect the filter housing with the water pump body. On the other hand, the snapping process needs to be carried out underwater, which is inconvenient.
[0004] 2. When the filter housing becomes clogged, the pump body is submerged below the water surface, so the staff cannot observe the blockage in time. This affects the normal operation of the water system and may even lead to pump pressure buildup or inlet blockage, thus reducing the pump's service life. Utility Model Content
[0005] To address the above problems, the purpose of this utility model is to provide a water pump that is clogging-proof and easy to clean, solving the problems of inconvenient installation and removal of the filter housing of existing submersible pumps, easy structural damage, and the inability of operators to observe the clogging of the submersible pump filter holes underwater in a timely manner.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water pump that is clogging-proof and easy to clean, comprising a submersible pump body, wherein the submersible pump body is sequentially connected to a water pump support, a flow guide cover, and a filter mechanism via extended bolts; the flow guide cover has an inlet and an outlet formed thereon; the filter mechanism is an L-shaped structure integrally formed from a cover and a housing; the housing has an inlet groove at one end facing the cover, which connects the filter mechanism and the flow guide cover; the cover has an inlet connector formed thereon; a filter plate is fitted into the groove of the housing; an indicator mechanism is installed on the filter plate; the indicator mechanism includes a connecting rod, the upper and lower ends of which are respectively connected to a float and a filter plate.
[0007] The beneficial effects of this utility model are as follows: the filter plate is magnetically attached to the filter mechanism, which can be quickly and conveniently installed and removed, improving the cleaning efficiency of the filter holes and the stability of the connection structure; the setting of the indicator mechanism allows personnel to intuitively and promptly observe whether the filter holes are blocked on the water surface; there is no need to change the structural shape of the submersible pump body, water pump support, and flow guide cover in the existing technology, and only the corresponding matching filter mechanism needs to be designed and manufactured to improve the submersible pump filter structure, which greatly reduces the modification cost of the device.
[0008] To ensure a tight fit between the filter mechanism and the flow guide cover;
[0009] As a further improvement to the above technical solution: the open end of the cover is adapted to snap onto the end of the guide cover facing away from the water pump support, and a groove adapted to fit the water outlet is provided on one side of the open end of the cover.
[0010] The beneficial effects of this improvement are: with the tightening connection of the extended bolts, the cover and the guide cover maintain a tight and stable fit, allowing water to be effectively drawn into the pump through the box and the inlet connector.
[0011] In order to make the float sink and move when the filter holes of the filter plate become clogged;
[0012] As a further improvement to the above technical solution: multiple support blocks are installed on the inner wall of the box, magnetic blocks are installed on the support blocks, and a spring is installed at the bottom of the filter plate, with the spring magnetically connected to the magnetic blocks.
[0013] The beneficial effects of this improvement are: when the filter plate is severely clogged, a negative pressure is formed inside the box, which causes the filter plate, supported by the spring, to be sucked into the box under the action of the negative pressure, thereby effectively driving the float to move downward.
[0014] To allow personnel to visually observe the float;
[0015] As a further improvement to the above technical solution: the surface of the float is sprayed with a coating of two colors, consisting of cool and warm pigments, at intervals.
[0016] The beneficial effects of this improvement are: the two-color pigment sprayed on the surface of the float gives the float high brightness and high contrast, enabling people to observe the float on the water surface in a timely manner in both sunny days with strong sunlight and cloudy days with poor light.
[0017] To further enhance the functionality of the device;
[0018] As a further improvement to the above technical solution: the axis of the water inlet is collinear with the axis of the water inlet connector.
[0019] The beneficial effects of this improvement are: the water pump can perform submersible pumping and pipeline pumping through the housing and the inlet connector respectively, and the inlet connector can be blocked when the pipeline pumping function is not needed.
[0020] To allow for flexible adjustment of the water inlet flow rate of the housing and inlet connector;
[0021] As a further improvement to the above technical solution: a flow regulating mechanism is installed on the box body on one side of the water inlet tank. The flow regulating mechanism includes a movable groove, which is opened on the side of the box body. A rotating rod is installed on the inner side of the movable groove, and a gate is installed on the part of the rotating rod located inside the box body. One end of the rotating rod is connected to a lever.
[0022] The beneficial effects of this improvement are as follows: by using a tool such as a long stick to press and rotate the lever, the gate can be rotated, thereby changing the height of the channel formed between the gate, the filter plate, and the box, and thus changing the ratio of the inlet flow rate of the water tank and the water supply pipeline.
[0023] To ensure the stability of the gate angle;
[0024] As a further improvement to the above technical solution: an outer frame is installed on the outer side of the box body outside the movable groove, and friction pads and springs are installed at intervals inside the outer frame. The top of the springs supports and connects to the rotating rod, and the bottom surface of the friction pads is adapted to fit the rotating rod.
[0025] The beneficial effects of this improvement are: when adjusting the angle of the gate, pressing down on the lever causes the rotating rod to disengage from the friction pad for smooth rotation; after adjustment, the lever moves upward under the elastic support of the spring and presses tightly against the friction pad, ensuring the stability of the gate angle.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0035] Example 1:
[0036] like Figure 1As shown in Figure 6: A water pump that is clogging-resistant and easy to clean includes a submersible pump body 1. The submersible pump body 1 is connected in sequence to a water pump support 2, a flow guide cover 3, and a filter mechanism 4 via an elongated bolt 8. The flow guide cover 3 has an inlet 31 and an outlet 32. The filter mechanism 4 is an L-shaped structure integrally formed by a cover 41 and a box 42. The box 42 has an inlet groove 45 at one end facing the cover 41, which connects the cavity between the filter mechanism 4 and the flow guide cover 3. The cover 41 has an inlet connector 43. A filter plate 6 is fitted into the groove of the box 42. An indicator mechanism 7 is installed on the filter plate 6. The indicator mechanism 7 includes a connecting rod 71. The upper and lower ends of the connecting rod 71 are respectively connected to a float 72 and the filter plate 6. The filter plate 6 is a magnetic cover installed on the filter mechanism 4, which can be quickly and easily installed and removed, improving the cleaning efficiency of the filter holes and the stability of the connection structure. The indicator mechanism 7 allows personnel to intuitively and promptly observe whether the filter holes are clogged on the water surface.No changes to the structural shape of the submersible pump body 1, pump support 2, and guide cover 3 in the existing technology are required. Only a corresponding matching filter mechanism 4 needs to be designed and manufactured to improve the submersible pump's filter structure, significantly reducing the modification cost. The open end of the cover 41 is adapted to snap onto the end of the guide cover 3 facing away from the pump support 2. A groove is provided on one side of the open end of the cover 41 to fit the outlet 32. With the tightening connection of the extension bolt 8, the cover 41 and the guide cover 3 maintain a tight and stable fit, allowing water to be effectively drawn into and pumped through the box 42 and the inlet connector 43. Multiple support blocks 44 are installed on the inner wall of the box 42, and the support blocks 44 are equipped with... The filter plate 6 is equipped with a magnetic block 46, and a spring 61 is installed at the bottom of the filter plate 6. The spring 61 is magnetically connected to the magnetic block 46. When the filter plate 6 is severely clogged, a negative pressure is formed inside the box 42, which causes the filter plate 6, supported by the spring 61, to be drawn into the box 42 under the action of the negative pressure, thereby effectively driving the float 72 to move downward. The surface of the float 72 is sprayed with two colors of paint, consisting of cool and warm colors, at intervals. The two-color paint sprayed on the surface of the float 72 gives the float 72 high brightness and high contrast, allowing people to observe the float 72 on the water surface in a timely manner in both sunny days with strong sunlight and cloudy days with poor lighting. The water inlet 31 The axis of the pump is collinear with the axis of the inlet connector 43. The pump can perform submersible pumping and pipeline pumping through the housing 42 and the inlet connector 43 respectively. When the pipeline pumping function is not needed, the inlet connector 43 can be blocked. A flow regulating mechanism 5 is installed on the housing 42 on one side of the inlet trough 45. The flow regulating mechanism 5 includes a movable groove 51, which is opened on the side of the housing 42. A rotating rod 52 is installed on the inner side of the movable groove 51. A gate plate 53 is installed on the part of the rotating rod 52 located inside the housing 42. One end of the rotating rod 52 is connected to a lever 57. By pressing the lever 57 with a tool such as a long stick, the gate plate 53 can be rotated. This changes the height of the channel formed between the gate 53, filter plate 6, and box 42, thereby altering the inflow rate ratio between the water tank and the water supply pipe. An outer frame 54 is installed on the outer surface of the box 42 outside the movable groove 51. Friction pads 55 and springs 56 are installed vertically and vertically inside the outer frame 54. The top of the spring 56 supports and connects to the rotating rod 52. The bottom surface of the friction pad 55 is fitted to the rotating rod 52. When adjusting the angle of the gate 53, pressing down on the lever 57 causes the rotating rod 52 to disengage from the friction pad 55 for smooth rotation. After adjustment, the lever 57 moves upward under the elastic support of the spring 56 and presses firmly against the friction pad 55, ensuring the stability of the gate 53's angle.
[0037] The working principle of this technical solution is as follows: The submersible pump body 1, pump support 2, guide cover 3, and filter mechanism 4 can be assembled into a single unit using the extended bolt 8 and nut. The inlet connector 43 is connected to the corresponding water supply pipeline, and the outlet 32 is connected to the corresponding outlet pipeline. The device is submerged in the water tank, with the top of the float 72 slightly above the water surface for easy observation. After the submersible pump body 1 is powered on, the pump simultaneously draws water from both the water tank and the water supply pipeline. The water in the tank is filtered through the filter plate 6 to remove large impurities. When it is necessary to adjust the inlet flow ratio between the water tank and the water supply pipeline, the operator uses a tool such as a wooden stick to press down on the lever 57 below the water surface, causing the rotating rod 52 to disengage from the friction plate. The friction pad 55 simultaneously presses the spring 56, and then the operator adjusts the pressing direction, causing the lever 57 to rotate to one side, which in turn drives the gate 53 to rotate, thereby changing the height of the channel formed between the gate 53, the filter plate 6, and the box 42, and thus changing the ratio of the water flow rate of the water tank and the water supply pipe. After the adjustment, the lever 57 moves up and sticks tightly to the friction pad 55 under the elastic support of the spring 56, ensuring the stability of the angle of the gate 53. When the filter holes are severely blocked, a negative pressure is formed inside the box 42, which causes the filter plate 6, supported by the spring 61, to be sucked into the box 42 under the action of the negative pressure, thereby effectively driving the float 72 to submerge below the water surface. When the operator cannot see the float 72, the filter plate 6 can be cleaned in time.
