Description

Technical Field

[0001] This utility model relates to the field of water pump anti-clogging, specifically a fire pump with an anti-clogging structure. Background Technology

[0002] Fire pumps play a vital role in building fire safety. Their performance directly affects the water supply efficiency and fire extinguishing effect during a fire. Once a fire occurs, fire pumps need to be started in time to provide sufficient water pressure and flow to ensure the normal operation of fire hydrants and sprinkler systems. Fire pumps mainly use impellers to convert power into the kinetic energy of water flow to extract water.

[0003] In existing technologies, traditional fire pumps mainly consist of components such as impellers, drive motors, mounting components, and pump bodies. The impeller is responsible for converting power into the kinetic energy of water flow, increasing water pressure and flow rate; the drive motor provides a stable power source for the pump, ensuring its timely start-up in emergencies; the mounting components are used to fix and connect the various components, ensuring smooth operation; and the pump body serves to contain the water flow and guide its direction. These components work together to ensure that the fire pump can supply water efficiently and reliably during a fire.

[0004] However, traditional fire pumps are prone to blockages during use due to impurities in the water, inadequate filtration devices, insufficient maintenance after long-term operation, or poor sealing at pipe connections. This can lead to the deposition of impurities or foreign objects entering the pump body, resulting in internal blockages and reduced water supply efficiency. To address these issues, this invention proposes a fire pump with an anti-blockage structure. Utility Model Content

The surface of the first assembly plate has a plurality of circumferentially equidistant mounting holes.

[0010] Preferably, the mounting ring is fixedly mounted on the inner wall surface of the upper end of the pump body. The mounting ring surface has several first threaded holes. The mounting ring surface is provided with a mounting plate. The mounting plate is a circular plate structure. The mounting plate surface has several holes. A first mounting screw is provided in the hole. The external thread of the first mounting screw is threaded to the first threaded hole. A connecting hole is provided at the center of the mounting plate surface. Several second threaded holes are arranged circumferentially around the connecting hole. A sealing ring is provided between the outer wall of the mounting plate and the inner wall of the pump body.

[0011] Preferably, the upper surface of the impeller is fixedly connected to one end of the pump shaft, the other end of the pump shaft is fixedly connected to the output end of the motor, a connecting seat is fixedly installed below the motor, a number of holes are opened on the bottom surface of the connecting seat, a second mounting screw is provided in the hole, the external thread of the second mounting screw is threaded to the second threaded hole, and the pump shaft is clamped in the connecting hole opened on the surface of the mounting plate.

[0012] Preferably, the bottom surface of the water inlet pipe has a hole, a mounting base is fixedly installed in the hole, a connecting shaft is fixedly installed on the surface of the mounting base, a fixed bearing is sleeved on the surface of the connecting shaft, the inner ring surface of the fixed bearing is fixedly connected to the outer wall of the connecting shaft, a connecting sleeve is fixedly installed on the outer ring surface of the fixed bearing, and a plurality of circumferentially equidistant flow aids are fixedly connected to the outer wall of the connecting sleeve, and a second assembly plate is fixedly installed at the end of the water inlet pipe away from the pump body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The fire pump with an anti-clogging structure proposed in this utility model can pump water by driving an impeller with an electric motor. During pumping, the impact force of the water flow will impact the flow aid plate, generating a torque that causes the flow aid plate to rotate. During the rotation of the flow aid plate, its edges cut the water flow, dividing it into smaller vortices or laminar flows, thereby breaking up the large-scale vortex and turbulent structure in the water flow, making the water flow smoother and more orderly, thus improving the water delivery efficiency. When debris enters the inlet pipe with the water flow, the rotation of the flow aid plate will generate a centrifugal force field. Under the action of centrifugal force, the denser debris will be pushed towards the pump body pipe wall area, while the central area will maintain a relatively clean water flow. In addition, the rotating edges of the flow aid plate will also physically block and disperse the debris, preventing it from agglomerating and causing blockage. This achieves efficient water delivery while preventing pump blockage, thus avoiding the problem of fire pumps being prone to clogging. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a fire pump with an anti-clogging structure, comprising: a pump body 1, an inlet pipe 2 installed at one end of the pump body 1, a flow aid plate 3 installed inside the inlet pipe 2, a drain pipe 4 installed at the other end of the pump body 1, and an installation ring 5 installed on the inner wall of the upper end of the pump body 1.

[0026] Impeller 6 is located inside pump body 1, and motor 7 is fixedly installed on the upper end of impeller 6.

[0027] During operation, the impeller 6 is driven by the motor 7 to pump water. When pumping, the impact force of the water flow impacts the flow aid plate 3, generating a torque that causes the flow aid plate 3 to rotate. As the flow aid plate 3 rotates, its edges cut the water flow, dividing it into smaller vortices or laminar flows. This breaks down large-scale vortices and turbulent structures in the water flow, making the water flow smoother and more orderly, thus improving the water delivery efficiency. When debris enters the inlet pipe 2 with the water flow, the rotation of the flow aid plate 3 generates a centrifugal force field. Under the action of centrifugal force, denser debris is pushed towards the pipe wall area of ​​the pump body 1, while the central area maintains a relatively clean water flow. In addition, the rotating edges of the flow aid plate 3 also physically block and disperse debris, preventing it from agglomerating and causing blockages. This achieves efficient water delivery while preventing pump blockages, thus avoiding the problem of fire pumps being prone to clogging.

[0028] Example 2: Based on Example 1, an inlet pipe 2 is provided to prevent water pump blockage. A hole is opened on the bottom surface of the inlet pipe 2, and a mounting base 16 is fixedly installed in the hole. A connecting shaft 17 is fixedly installed on the surface of the mounting base 16. A fixed bearing 18 is sleeved on the surface of the connecting shaft 17. The inner ring surface of the fixed bearing 18 is fixedly connected to the outer wall of the connecting shaft 17. A connecting sleeve 19 is fixedly installed on the outer ring surface of the fixed bearing 18. Several circumferentially spaced flow aid plates 3 are fixedly connected to the outer wall of the connecting sleeve 19. A second assembly plate 20 is fixedly installed at the end of the inlet pipe 2 away from the pump body 1. The upper surface of the impeller 6 is fixedly connected to one end of the pump shaft 13. The other end of the pump shaft 13 is fixedly connected to the output end of the motor 7. A connecting base 14 is fixedly installed below the motor 7. Several holes are opened on the bottom surface of the connecting base 14. A second mounting screw 15 is provided in the hole. The second mounting screw 15 is threaded to the second threaded hole. The pump shaft 13 is completely locked in the connecting hole opened on the surface of the mounting plate 11.

[0029] To prevent pump blockage, during the pumping process driven by the motor 7 and impeller 6, the water flow impacts the flow aid plate 3 at a certain speed and pressure. With the coordinated action of the fixed bearing 18 and connecting sleeve 19, the flow aid plate 3 can rotate around the connecting shaft 17. During this rotation, the edges of the flow aid plate 3 cut through the water flow, dividing it into smaller vortices or laminar flows. This breaks down large-scale vortices and turbulent structures in the water flow, making it smoother and more orderly. This smooth water flow helps reduce resistance within the pipe and improves efficiency. The efficient water delivery achieves a flow-aiding effect. At the same time, the rotation of the flow-aiding plate 3 also plays a role in preventing blockage. When debris (such as leaves, mud, etc.) enters the inlet pipe 2 with the water flow, the rotation of the flow-aiding plate 3 generates a centrifugal force field. Under the action of centrifugal force, the denser debris will be pushed towards the pipe wall area of ​​the pump body 1, while the central area maintains a relatively clean water flow. In addition, the rotating edge of the flow-aiding plate 3 will also physically block and disperse the debris, preventing it from agglomerating and causing blockage, thus achieving efficient water delivery while preventing blockage.

[0030] Example 3: Based on Example 2, in order to make the overall device more convenient and durable, an installation ring 5 is provided. The installation ring 5 is fixedly installed on the inner wall surface of the upper end of the pump body 1. The surface of the installation ring 5 has a number of first threaded holes. The surface of the installation ring 5 is provided with an installation plate 11. The installation plate 11 is a circular plate structure. The surface of the installation plate 11 has a number of holes. The holes are provided with first installation screws 12. The first installation screws 12 are externally threaded and threadedly connected to the first threaded holes. A connecting hole is provided at the center of the surface of the installation plate 11. A number of second threaded holes are circumferentially arranged around the connecting hole. A sealing ring is provided between the outer wall of the installation plate 11 and the inner wall of the pump body 1.

[0031] For ease of use, the operator can rotate the first mounting screw 12 on the surface of the mounting plate 11 to disengage it from the first threaded hole on the surface of the mounting ring 5, thereby removing the mounting plate 11 from the surface of the pump body 1 as a whole, which makes it convenient for the operator to perform regular maintenance on the impeller 6 and the pump shaft 13.

[0032] The pump body 1 has a cylindrical structure. A drain hole is provided on one side wall of the pump body 1. A drain pipe 4 is fixedly installed in front of the drain hole. A fixed base 10 is fixedly installed at the bottom of the pump body 1. Several linearly equidistant reinforcing ribs are fixedly installed on the outer wall of the fixed base 10. One end of the drain pipe 4 is fixedly connected to the drain hole on the side wall of the pump body 1. A reinforcing plate 8 is fixedly installed between the drain pipe 4 and the side wall of the pump body 1. A first assembly plate 9 is fixedly installed at the end of the drain pipe 4 away from the pump body 1. Several circumferentially equidistant mounting holes are provided on the surface of the first assembly plate 9.

[0033] To make the overall structure more stable and durable, several reinforcing ribs are fixedly installed on the outer wall of the fixed base 10 at the bottom of the pump body 1. The reinforcing ribs can effectively enhance the stability of the overall components. At the same time, a reinforcing plate 8 is fixedly installed between the drain pipe 4 and the pump body 1. The reinforcing plate 8 can provide a certain support for the drain pipe 4, thereby making the overall structure more stable and improving the service life of the device.

[0034] In actual use, the impeller 6 can be driven by the motor 7 to pump water. When pumping water, the impact force of the water flow will impact the flow aid plate 3, generating a torque during the impact process, causing the flow aid plate 3 to start rotating. During the rotation of the flow aid plate 3, its edge cuts the water flow, dividing the water flow into smaller vortices or laminar flows, thereby breaking the large-scale vortex and turbulent structure in the water flow, making the water flow smoother and more orderly, thus improving the water delivery efficiency. When debris enters the inlet pipe 2 with the water flow, the rotation of the flow aid plate 3 will generate a centrifugal force field. Under the action of centrifugal force, the denser debris will be pushed towards the pipe wall area of ​​the pump body 1, while the central area will maintain a relatively clean water flow. In addition, the rotating edge of the flow aid plate 3 will also physically block and disperse the debris, preventing it from agglomerating and causing blockage. This achieves efficient water delivery while preventing pump blockage, thus avoiding the problem of easy blockage of fire pumps.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
