Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a booster energy-saving water pump with good sealing performance. Background Technology

[0002] Water pumps, as core equipment for fluid transportation, are widely used in industrial production, agricultural irrigation, and daily life. In many applications, the medium pumped is not pure water, but liquids containing impurities, silt, or high-viscosity slurries and chemical raw materials. These special media easily adhere to and deposit on the inner wall of the pipe, especially in the outlet section, forming a layer of dirt.

[0003] Over time, the accumulation of fouling buildup gradually reduces the effective flow cross-section of pipes, increasing resistance to fluid transport. To maintain the rated flow rate, the pump must consume more energy to overcome the increased resistance, leading to energy waste. In severe cases, fouling can even cause pipe blockage, forcing the entire system to shut down and affecting the continuity and stability of production. Traditional solutions typically involve periodic shutdowns for manual disassembly and physical or chemical cleaning of the pipes. This process is not only time-consuming and labor-intensive, increasing maintenance costs, but frequent disassembly and reassembly can also damage the pipe's sealing performance.

[0004] To address the drawbacks of manual cleaning, existing technologies have developed pipeline components with online cleaning capabilities. These typically incorporate fixed or movable cleaning scrapers and brushes inside the pipes. However, these online cleaning devices themselves face wear, damage, and accumulating dirt after prolonged use. More importantly, when the cleaning device needs repair or replacement, or when deep cleaning is required on areas inaccessible to the device, complex disassembly of the entire pipeline assembly is still necessary. This significantly reduces the convenience of online cleaning and fails to fundamentally solve the core problem of inconvenient maintenance.

[0005] Therefore, this utility model proposes a booster pump with good sealing performance to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a booster energy-saving water pump with good sealing performance, which aims to improve the problems of existing water pumps, such as the difficulty in disassembling and maintaining the cleaning device itself, and the inability to effectively clean the dead corners inside the pipes.

[0007] To achieve the above objectives, this utility model provides a booster energy-saving water pump with good sealing performance, comprising: a pump body and an outlet pipe in fluid communication with the pump body; as well as a wall scraping assembly and a clamping mechanism.

[0008] The wall scraping assembly is detachably mounted at the end of the water outlet pipe. The wall scraping assembly includes a scraper for scraping off impurities from the inner wall of the water outlet pipe and a motor for driving the scraper to rotate about the central axis of the water outlet pipe.

[0009] The clamping mechanism is used to fix the scraper assembly to or detach it from the water outlet pipe. The clamping mechanism includes multiple grippers and an electric push rod for driving the grippers to clamp or release the water outlet pipe synchronously.

[0010] Preferably, the scraper assembly further includes a worm gear connected to the output shaft of the motor and a worm wheel meshing with the worm gear. The worm wheel is coaxially disposed outside the water outlet pipe, and the scraper is fixedly connected to the worm wheel.

[0011] Preferably, the wall scraping assembly further includes a connecting plate, a receiving member, and an anti-detachment rod. The motor and worm gear are mounted on the connecting plate, and the receiving member and anti-detachment rod are used to connect and stabilize the clamping mechanism with the rest of the wall scraping assembly.

[0012] Preferably, the clamping mechanism further includes multiple rotating shafts, through which the pushing and pulling action of the electric push rod is transmitted to the gripper to drive the gripper to swing.

[0013] Preferably, the clamping mechanism further includes a connector and a limiting rod. The connector connects the electric push rod to the rotating shaft. One end of the gripper is rotatably connected to the rotating shaft, and the other end is slidably connected to the limiting rod to limit the movement trajectory of the gripper.

[0014] Preferably, the clamping mechanism further includes a controller electrically connected to an electric push rod for controlling its extension and retraction.

[0015] Preferably, it also includes an inlet pipe, a pressurizing device located inside the pump body, a first ball valve located on the inlet pipe, and a second ball valve located on the outlet pipe.

[0016] Preferably, the scraping plane of the scraper is perpendicular to the axis of the water outlet pipe.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a rotatable wall scraping component, which is driven by a motor to scrape the inner wall of the water outlet pipe, the problem of the impurities attached to the inner wall of the water outlet pipe being difficult to clean and requiring machine shutdown and disassembly in the prior art is solved, and the technical effects of online automatic cleaning, improved cleaning efficiency and reduced labor costs are achieved.

[0018] 2. This utility model, by setting up a clamping mechanism in which multiple grippers are opened and closed synchronously by an electric push rod, realizes the rapid fixation and separation of the wall scraping component and the water outlet pipe. It solves the problem that the cleaning device itself is difficult to maintain and cannot thoroughly clean the dead corner area inside the pipe in the prior art. It achieves the technical effect of facilitating deep cleaning of the wall scraping component and dead corner of the pipe, quick repair and replacement, and greatly improving the practicality of the device.

[0021] 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.

[0022] Reference Figures 1-4 This utility model provides a booster energy-saving water pump with good sealing performance, which aims to solve the problems in the prior art where it is difficult to clean impurities attached to the inner wall of the water pump outlet pipe online, and the cleaning device itself is difficult to disassemble and maintain, resulting in poor practicality.

[0023] Specifically, it includes a pump body 1, a pressurizing device 2 located inside the pump body 1, an inlet pipe 3 connected to the pump body 1, and an outlet pipe 5 in fluid communication with the pump body 1. A first ball valve 4 is installed on the inlet pipe 3, and a second ball valve 6 is installed on the outlet pipe 5.

[0024] The water pump also includes a wall scraping assembly 7 and a clamping mechanism 8. The wall scraping assembly 7 is detachably installed at the end of the outlet pipe 5. The clamping mechanism 8 is used to quickly fix and separate the wall scraping assembly 7 from the outlet pipe 5. Specifically, the wall scraping assembly 7 includes a scraper 706 for scraping away impurities from the inner wall of the outlet pipe 5 and a motor 702 for driving the scraper 706 to rotate around the central axis of the outlet pipe 5. The clamping mechanism 8 includes multiple grippers 805 and an electric push rod 802 for driving the grippers 805 to simultaneously clamp or release the outlet pipe 5. The wall scraping assembly 7 is fixed to the outer wall of the outlet pipe 5 by the clamping mechanism 8. The motor 702 is mounted on the connecting plate 701, and the controller 803 is electrically connected to the electric push rod 802. The rod 802 is used to control its extension and retraction. The electric push rod 802 is connected to multiple rotating shafts 804 through the connector 801. Multiple grippers 805 are connected to the rotating shafts 804 and the limiting rods 806 respectively. One end of the gripper 805 is rotatably connected to the rotating shaft 804, and the other end is slidably connected to the limiting rod 806. Thus, under the pushing and pulling action of the electric push rod 802, the multiple grippers 805 can synchronously clamp inward or release outward about the water outlet pipe 5 with the rotating shaft 804 as the axis. The wall scraping assembly 7 also includes a receiving part 705 and an anti-detachment rod 707. Both the receiving part 705 and the anti-detachment rod 707 are connected to the clamping mechanism 8 to enhance the stability of the connection between the wall scraping assembly 7 and the clamping mechanism 8.

[0025] In a preferred embodiment, to achieve stable wall-scraping cleaning action, the wall-scraping assembly 7 specifically includes a worm 703 connected to the output shaft of the motor 702 and a worm wheel 704 meshing with the worm 703. The worm wheel 704 is coaxially disposed outside the water outlet pipe 5, and the scraper 706 is fixedly connected to the worm wheel 704. Through transmission, the motor 702 can efficiently drive the scraper 706 to rotate. Furthermore, to ensure the smoothness and reliability of the wall-scraping action, the scraping plane of the scraper 706 is perpendicular to the axis of the water outlet pipe 5.

[0026] To improve the overall structural strength and installation stability of the wall scraping assembly 7, the wall scraping assembly 7 also includes a connecting plate 701, a receiving part 705, and an anti-detachment rod 707. The motor 702 and the worm gear 703 are both mounted on the connecting plate 701, while the receiving part 705 and the anti-detachment rod 707 are used to connect and stabilize the clamping mechanism 8 and the rest of the wall scraping assembly 7, forming a stable whole.

[0027] To achieve reliable synchronous clamping and releasing of the water outlet pipe 5, the internal transmission structure of the clamping mechanism 8 includes multiple rotating shafts 804. The pushing and pulling action of the electric push rod 802 is transmitted to the gripper 805 through the rotating shafts 804 to drive the gripper 805 to swing synchronously. Specifically, the clamping mechanism 8 is also provided with a connecting piece 801 and a limiting rod 806. The connecting piece 801 connects the electric push rod 802 and the rotating shafts 804. One end of the gripper 805 is rotatably connected to the rotating shaft 804, and the other end is slidably connected to the limiting rod 806. This linkage structure precisely limits the movement trajectory of the gripper 805, ensuring the accuracy and reliability of the clamping action.

[0028] To achieve automated control of the clamping mechanism 8, the clamping mechanism 8 also includes a controller 803, which is electrically connected to the electric push rod 802 and is used to precisely control the extension and retraction stroke and start and stop of the electric push rod 802.

[0029] It also includes an inlet pipe 3, a pressurizing device 2 located inside the pump body 1, a first ball valve 4 located on the inlet pipe 3, and a second ball valve 6 located on the outlet pipe 5. The first ball valve 4 and the second ball valve 6 are used to control the opening and closing and sealing of the pipeline.

[0030] Working principle: First, water is sent into the pump body 1 through the inlet pipe 3, and then pumped to the outlet pipe 5 by the pressurizing device 2. During this process, the first ball valve 4 and the second ball valve 6 can limit and seal at their respective positions as needed to prevent water leakage.

[0031] When it is necessary to remove impurities attached to the inner wall of the water outlet pipe 5, the wall scraping assembly 7 is operated, and the motor 702 on the side wall of the connecting plate 701 is started to drive the worm gear 703 to rotate. Through the meshing relationship with the worm wheel 704, the worm wheel 704 is driven to rotate, thereby driving the scraper 706 on one side to scrape off the impurities attached to the inner wall of the water outlet pipe 5. The receiving part 705 and the anti-detachment rod 707 are both connected to the clamping mechanism 8. The mutual connection makes the wall scraping assembly 7 more stable and prevents it from falling off due to external forces.

[0032] When the scraper 706 encounters hard-to-clean corners during the scraping process, the clamping mechanism 8 is operated. The controller 803 drives the electric push rod 802 to push or retract, thereby driving multiple rotating shafts 804 connected to it. The grippers 805 are connected to the rotating shafts 804 and the limiting rods 806 respectively. Through the limiting action of the limiting rods 806 and the connection of the connecting piece 801, the force driven by the electric push rod 802 drives the multiple grippers 805 to swing synchronously inward or outward around the rotating shafts 804 and the end connected to the limiting rods 806, thereby achieving the effect of fixing or loosening the water outlet pipe 5. The clamping mechanism 8 can detach the wall scraping assembly 7 from the water outlet pipe 5, thereby cleaning the scraper 706 and thoroughly removing impurities from the dead corner areas inside the water outlet pipe 5, further improving cleaning efficiency. When a component is damaged, it can also be quickly replaced and repaired, greatly improving the practicality of the component.
