Description
Technical Field
[0001] This utility model relates to the field of energy-saving water pump technology, and in particular to an energy-saving water pump that prevents backflow. Background Technology
[0002] Traditional water pumps, as core equipment in fluid transportation, are widely used in various fields such as agricultural irrigation, industrial production, building water supply and drainage, and municipal water supply. Their main function is to convert mechanical energy into the pressure energy and kinetic energy of the fluid by driving the impeller to rotate through a motor, thereby realizing the directional transportation of the fluid.
[0003] In the current field of energy-saving water pumps, a variety of anti-backflow technologies have been applied. Some energy-saving water pumps incorporate anti-backflow structures at the water outlet, such as symmetrically arranged rotating plates inside the pipe. When the water pump is working, the water flow can open the rotating plates. When the water pump stops working, the rotating plates close the pipe under the restoring force of the spring, preventing the water flow from flowing back due to inertia due to loss of pressure.
[0004] The existing technology does not include auxiliary fixing devices, which leads to the water pipe and interface being in an unstable state for a long time due to the unavoidable vibration during the operation of the water pump and the pressure fluctuation caused by the water flow in the pipeline. This not only easily causes pipeline displacement and shaking, but also accelerates the wear at the interface and the aging of the seals, thus causing water leakage. Therefore, an energy-saving water pump with anti-backflow is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an energy-saving water pump that prevents backflow. It aims to improve the existing technology by not adding auxiliary fixing devices, which causes the water pipe and interface to be in an unstable state for a long time, aggravates the wear at the interface and the aging of the seals, and thus causes water leakage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An energy-saving water pump with backflow prevention includes a support base, a water pump fixedly connected to the top of the support base, an inlet pipe fixedly connected to the outside of the water pump, a conical filter movably connected inside the inlet pipe, an outlet pipe fixedly connected to the top of the support base, an auxiliary docking mechanism fixedly connected inside the outlet pipe, and a quick replacement mechanism fixedly connected inside the inlet pipe.
[0008] The auxiliary docking mechanism includes a connecting rod, which is slidably connected to the outside of the outlet pipe. One end of the connecting rod is fixedly connected to a rotating shaft, and a slider is fixedly connected to the outside of the rotating shaft. Multiple sliding grooves are opened inside the rotating shaft, and a clamping mechanism is slidably connected inside the sliding grooves.
[0009] As a further description of the above technical solution:
[0010] The quick replacement mechanism includes two sliding columns, both of which are slidably connected to the inside of the inlet pipe, and one end of each sliding column is fixedly connected to a locking pin.
[0011] As a further description of the above technical solution:
[0012] A spring is fixedly connected to the outside of the locking post, and a rotating rod is rotatably connected to the other end of the sliding post;
[0013] As a further description of the above technical solution:
[0014] The clamping mechanism includes multiple sliding rods, the outside of which are slidably connected to the inside of multiple sliding grooves, and a sliding plate is fixedly connected to the bottom of each sliding rod;
[0015] As a further description of the above technical solution:
[0016] The other end of the spring is fixedly connected to the inside of the inlet pipe, and the outside of the retaining pin is slidably connected to the inside of the cone filter;
[0017] As a further description of the above technical solution:
[0018] The slider is externally slidably connected to the inside of the outlet pipe, and the rotating shaft is externally rotatably connected to the inside of the outlet pipe.
[0019] As a further description of the above technical solution:
[0020] The sliding rod is slidably connected to the outside of the rotating shaft, and the sliding plate is slidably connected to the outside of the rotating shaft.
[0021] As a further description of the above technical solution:
[0022] An operating block is fixedly connected to the outside of the rotating rod, and the operating block rotates outside the inlet pipe.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the rotating connecting rod drives the rotating shaft to make a circular motion inside the outlet pipe. When the rotating shaft rotates, it drives multiple sliding rods to slide along multiple sliding grooves inside. When the sliding rods slide to the right along the sliding grooves, they drive multiple sliding plates to slide inward inside the rotating shaft. When the sliding rods slide to the limit position, the sliding plates will lock the outside of the water pipe, thereby fixing the water pipe and facilitating connection. Compared with the prior art, it can effectively prevent the energy-saving water pump outlet pipe from shifting due to pipe vibration when connecting with the water pipe.
[0025] 2. In this utility model, the operating block drives the rotating rod to rotate inside the sliding column, thereby causing the sliding column to slide outward inside the inlet pipe. The sliding column causes the locking column to slide outward in the slot of the cone filter and compress the spring. When the locking column is no longer in contact with the cone filter, the lock is released for cleaning or replacement. After the operating block is rotated in the opposite direction, the spring drives all components to reset. During the process of the cone filter sliding into the inlet pipe, it first pushes the locking column outward. When its own slot reaches the locking column position, the locking column slides into the slot and completes the locking, realizing the quick disassembly and installation of the cone filter.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example:
[0037] An energy-saving water pump with backflow prevention, as described in reference Figures 1 to 3 The system includes a support base 1, which securely supports the entire water pump and prevents it from shaking during operation. A water pump 2 is fixedly connected to the top of the support base 1. The water pump 2 is the core of the water delivery system, capable of drawing and transporting water. An inlet pipe 3 is fixedly connected externally to the water pump 2, providing a channel for water to enter the pump 2. A conical filter 4 is movably connected inside the inlet pipe 3, filtering impurities in the water and protecting the pump 2. An outlet pipe 5 is fixedly connected to the top of the support base 1, used to output the water transported by the pump 2. An auxiliary docking mechanism 6 is fixedly connected inside the outlet pipe 5, preventing displacement due to vibration when the outlet pipe 5 is docked with the water pipe. The inlet pipe 3... The fixed connection includes a quick-change mechanism 7, which facilitates the rapid replacement of the conical filter 4. The auxiliary docking mechanism 6 includes a connecting rod 61, which is an auxiliary docking operating component. The connecting rod 61 is externally slidably connected to the outside of the outlet pipe 5. This connection method allows the connecting rod 61 to rotate flexibly. One end of the connecting rod 61 is fixedly connected to a rotating shaft 62. The rotation of the connecting rod 61 can drive the rotating shaft 62 to move. The rotating shaft 62 is externally fixedly connected to a slider 63, which can enhance the stability of the rotating shaft 62's movement. The rotating shaft 62 has multiple sliding grooves 64 inside, providing a path for the sliding of subsequent components. The sliding grooves 64 are internally slidably connected to a clamping mechanism 65, which can clamp the water pipe to achieve fixation.
[0038] Specifically, during startup, the support base 1 firmly supports the overall structure, preventing the water pump 2 from shaking during operation. The water pump 2, as the core water delivery component, starts up, and water enters through the inlet pipe 3. The internal conical filter 4 simultaneously filters impurities in the water to protect the water pump 2. The filtered water is pressurized by the water pump 2 and delivered to the outlet pipe 5. The auxiliary docking mechanism 6 in the outlet pipe 5 is connected to the external sliding connecting rod 61. When docking with the external water pipe, the position can be flexibly and slightly adjusted with vibration to prevent docking misalignment. When the conical filter 4 needs to be replaced, the quick replacement mechanism 7 in the inlet pipe 3 can be operated to quickly complete the filter disassembly and reinstallation. Rotating the connecting rod 61 will drive the rotating shaft 62 to make a rightward circular motion in the outlet pipe 5. The rotating shaft 62 is kept stable by the slider 63. The entire process does not affect the foundation support and water delivery function, achieving the synergy of anti-backflow and energy-saving operation.
[0039] When the connecting rod 61 is rotated to the right, the connecting rod 61 drives the rotating shaft 62 to move in a rightward circular motion within the outlet pipe 5. The clamping mechanism 65 includes multiple sliding rods 651, and a sliding plate 652 is fixedly connected to the bottom of each sliding rod 651. The rotation of the rotating shaft 62 drives the multiple sliding rods 651 to slide along the sliding groove 64. The sliding of the sliding rods 651 drives the sliding plate 652 to move. When the sliding rods 651 slide to their limit, the sliding plate 652 clamps the outside of the water pipe, thus fixing the water pipe. The quick replacement mechanism 7 includes two sliding columns 71. One end of each sliding column 71 is fixedly connected to a locking column 72, and the other end of each sliding column 71 is rotatably connected to a rotating rod 74. An operating block is fixedly connected to the outside of the rotating rod 74. 75. A spring 73 is fixedly connected to the external of the locking post 72. When the conical filter 4 needs to be replaced, the operating block 75 is rotated at both ends. The operating block 75 drives the rotating rod 74 to rotate inside the sliding post 71. The rotation of the rotating rod 74 causes the sliding post 71 to slide out of the inlet pipe 3. The sliding post 71 drives the locking post 72 to slide out of the slot of the conical filter 4. At the same time, the spring 73 is compressed. After the locking post 72 is released from the conical filter 4, it can be cleaned or replaced. The operating block 75 is rotated in the opposite direction. The spring 73 drives the component to reset and slide the conical filter 4 into the inlet pipe 3. When it contacts the locking post 72, it pushes the locking post 72 out. When the slot is aligned with the locking post 72, the locking post 72 slides into the slot and completes the locking.
[0040] Specifically, when the structure is working, the sliding groove 64 guides the sliding rod 651 of the clamping mechanism 65 to slide, pushing the sliding plate 652 to clamp the water pipe to achieve fixed connection. When replacing the conical filter 4, the operating block 75 is rotated to make the rotating rod 74 drive the sliding column 71 to slide out of the inlet end pipe 3. The locking column 72 disengages from the filter slot and compresses the spring 73 to release the lock for replacement. When resetting, the spring 73 pushes the locking column 72 to reset. When the filter slides in, it pushes out the locking column 72. After the slot is aligned, the locking column 72 slides in to complete the locking.
[0041] Reference Figure 1 , Figure 3 and Figure 4 The two sliding posts 71 can slide flexibly inside the inlet pipe 3 to achieve position adjustment. The outside of the two sliding posts 71 is slidably connected to the inside of the inlet pipe 3. The locking post 72 can cooperate with the locking groove of the conical filter 4 to achieve locking or unlocking function. The spring 73 can provide a restoring force to ensure that the locking post 72 can automatically lock into the locking groove. The rotation of the rotating rod 74 can drive the sliding post 71 to slide inside the inlet pipe 3. The other end of the spring 73 is fixedly connected to the inside of the inlet pipe 3, which can provide fixed support for the spring 73 so that it can extend and retract normally. The outside of the locking post 72 is slidably connected to the inside of the conical filter 4. The locking and unlocking of the conical filter 4 is achieved by the sliding of the locking post 72 inside the conical filter 4.
[0042] Specifically, the quick-change mechanism 7 achieves rapid locking and unlocking of the conical filter 4 through the coordinated movement of the sliding column 71, the locking column 72, the spring 73, and the rotating rod 74. In the initial state, the spring 73 is in a natural extension and contraction state, and its restoring force pushes the locking column 72 into the slot of the conical filter 4 to complete the locking. At this time, the sliding column 71 is stably stopped in the corresponding position in the inlet pipe 3 due to the limitation of the locking column 72. When the filter needs to be replaced, the rotating rod 74 is rotated, and its rotation will drive the sliding column 71 to slide in the inlet pipe 3. The sliding column 71 simultaneously pulls the locking column 72 out of the slot, and the spring 73 is stretched and stored. After the rotating rod 74 is released, the spring 73 releases the restoring force, pulls the sliding column 71 back, and the locking column 72 slides back into the slot, restoring the locked state.
[0043] Reference Figures 2 to 4 These sliding rods 651 can move along a specific trajectory to achieve a clamping function. Multiple sliding rods 651 are externally slidably connected to the interior of multiple sliding grooves 64. The sliding grooves 64 provide a sliding path and guidance for the sliding rods 651. The movement of the sliding rods 651 synchronously drives the sliding plate 652 to move. The slider 63 is externally slidably connected to the interior of the outlet pipe 5. The slider 63 can slide within the outlet pipe 5 to cooperate with the overall mechanism's movement. The rotating shaft 62 is externally rotatably connected to the interior of the outlet pipe 5. The rotating shaft 62 can... The outlet pipe 5 rotates to transmit power. The external sliding rod 651 is slidably connected to the inside of the rotating shaft 62, allowing the sliding rod 651 to slide relative to the rotating shaft 62. The external sliding plate 652 is slidably connected to the inside of the rotating shaft 62, allowing the sliding plate 652 to move within the rotating shaft 62 to achieve a locking action. The rotation of the operating block 75 can drive the rotating rod 74 to rotate synchronously. The external rotation of the operating block 75 is outside the inlet pipe 3. By rotating the operating block 75, the relevant components can be controlled to lock and unlock the cone filter 4.
[0044] Specifically, when the operating block 75 is rotated, it drives the rotating rod 74 to rotate synchronously, thereby locking and unlocking the cone filter 4. The rotating shaft 62 rotates within the outlet pipe 5 to transmit power. The sliding rod 651 slides inside the rotating shaft 62, while its exterior moves along a specific trajectory of the sliding groove 64. The sliding groove 64 acts as a guide. The movement of the sliding rod 651 synchronously drives the bottom sliding plate 652, causing the sliding plate 652 to move within the rotating shaft 62 to achieve a clamping action. The slider 63 slides within the outlet pipe 5, coordinating with the overall action of the clamping mechanism 65. The clamping function is completed through the linkage of various components.
[0045] The implementation principle of this application embodiment is as follows: to prevent the pipeline from vibrating and shifting when the outlet pipe 5 of the energy-saving water pump is connected to the water pipe, the connecting rod 61 is rotated to the right. When the connecting rod 61 rotates, it drives the rotating shaft 62 to make a circular motion to the right inside the outlet pipe 5. When the rotating shaft 62 rotates, it drives multiple sliding rods 651 to slide along multiple sliding grooves 64 inside the rotating shaft 62. When the multiple sliding rods 651 slide to the right along the sliding grooves 64, it drives multiple sliding plates 652 to slide inward inside the rotating shaft 62. When the multiple sliding rods 651 slide to the right along the sliding grooves 64 until they can no longer slide, the interior of the multiple sliding plates 652 clamps the exterior of the water pipe to fix the water pipe and facilitate connection.
[0046] When the conical filter 4 needs to be quickly replaced, rotate the two operating blocks 75 to the left and right respectively. The rotation of the two operating blocks 75 drives the two rotating rods 74 to rotate left and right respectively inside the two sliding pillars 71. When the two rotating rods 74 rotate, they drive the two sliding pillars 71 to slide outward inside the inlet pipe 3. When the two sliding pillars 71 slide outward inside the inlet pipe 3, they drive the two locking pillars 72 to slide outward inside the locking grooves of the conical filter 4. The outward sliding of the locking pillars 72 causes the two springs 73 to compress. When the two locking pillars 72 slide out of contact with the conical filter 4, the lock is released, and the conical filter 4 is cleaned or replaced. Rotate the two operating blocks 75 in opposite directions respectively. Then the two springs 73 drive the components to reset, and slide the conical filter 4 into the inlet pipe 3. When the conical filter 4 slides to contact the two locking pillars 72, it pushes the two locking pillars 72 outward. When the two locking grooves on the conical filter 4 slide to the two locking pillars 72, the two locking pillars 72 slide into the two locking grooves, completing the locking.
