Description

Technical Field

[0001] This invention relates to the field of flood control and disaster relief equipment technology, and more specifically, to an energy-saving flood control and disaster relief pump. Background Technology

[0002] Flood control and emergency pumps are equipment used to deal with floods during the flood season. Flood control and emergency pumps need to work for a long time, which leads to high temperatures. Some existing flood control and emergency pumps do not have sufficient heat dissipation capacity, which can easily increase the workload of the pumps and result in a shorter service life. In addition, some existing flood control and emergency pumps are not easy to carry and move, which causes inconvenience to their use.

[0003] A search revealed a portable flood control and emergency rescue pump with announcement number CN211448928U, comprising a placement plate, a fastening mechanism, a walking mechanism, a lifting mechanism, a cooling mechanism, and a waterproof box. This portable flood control and emergency rescue pump improves heat dissipation, does not increase the workload of the pump, extends its service life, and is easy to move and transport, bringing convenience to its use.

[0004] However, in the aforementioned flood control and emergency pumps, the pump body and motor are integrated. For deeper water surfaces, the pump body and motor are submerged in the water, which places high demands on the waterproof performance of the motor. If water gets into the motor, it is prone to short circuit, reducing the safety of use. Summary of the Invention

[0035] Example 1, please refer to Figure 1-11 The present invention provides the following technical solutions:

[0036] An energy-saving flood control and emergency pump, specifically, includes an emergency pump 1 and an energy-saving electric motor 2 for driving the emergency pump 1; the emergency pump 1 includes an installation cylinder 3; a pump body 4 is fixedly installed on the bottom surface of the installation cylinder 3;

[0037] The energy-saving electric motor 2 includes a top cover 5; the bottom surface of the top cover 5 is fixedly mounted with an electric motor body 6; the output end of the electric motor body 6 is fixed with a bushing 7; the top of the pump body 4 is rotatably equipped with a drive shaft 8 that is compatible with the bushing 7; ear plates 9 are symmetrically fixed on the sides of the top cover 5; and a lifting plate 10 is fixed on the bottom surface of the ear plates 9.

[0038] The lifting plate 10 has ear seats 11 fixed on its side; a connecting ring 12 is fixed between the two ear seats 11; an extension rod 13 is symmetrically fixed on the side of the connecting ring 12; a ball head 14 is fixed at the end of the extension rod 13; and a buoyancy part 15 adapted to the ball head 14 is symmetrically slidably arranged on the outer side of the mounting cylinder 3.

[0039] Working principle of this embodiment:

[0040] By controlling the energy-saving motor 2 to rise away from the emergency pump 1, the two buoyancy parts 15 are driven to slide and unfold away from the emergency pump 1, which improves the buoyancy performance of the entire device, so that the energy-saving flood control and emergency pump floats on the water surface, avoids water entering the motor body 6, improves the safety performance of the motor body 6, and improves the stability of the overall device operation.

[0041] Example 2, please refer to Figure 1-11 This second embodiment is an improvement on the first embodiment. Specifically, the inner circumferential side of the mounting cylinder 3 is symmetrically provided with lifting grooves 16 that slide with the lifting plate 10; the outer circumferential side of the mounting cylinder 3 is evenly provided with several weight-reducing grooves 22; an annular handle 17 is fixed between the two ear plates 9; the drive shaft 8 is symmetrically fixed with insert rails 18; the inner wall of the bushing 7 is symmetrically provided with limiting grooves 19 that slide with the insert rails 18.

[0042] The mounting cylinder 3 has symmetrical clearance grooves 20 on its outer periphery; extension plates 21 are symmetrically fixed on the outer periphery of the mounting cylinder 3; guide grooves 23 communicating with clearance grooves 20 are formed on the surface of extension plates 21; the buoyancy part 15 includes an Ω-shaped plate 24; a sliding plate 25 that slides with the guide groove 23 is fixed on the inner wall of the Ω-shaped plate 24; an inclined guide plate 26 adapted to the ball head 14 is fixed on the surface of the sliding plate 25; a tension spring 27 is fixed between one end of the sliding plate 25 and the inner wall of the guide groove 23. The outer periphery of the mounting cylinder 3 is symmetrically provided with arc-shaped grooves 28 on both sides of the clearance groove 20; the top and bottom of the arc-shaped grooves 28 are provided with positioning grooves 29; an arc-shaped baffle 30 is slidably provided inside the arc-shaped groove 28; the surface and bottom of the arc-shaped baffle 30 are fixed with arc-shaped rails 31 that slide with the corresponding positioning grooves 29; a fastening screw 32 is threaded through the outer wall of the arc-shaped baffle 30; and a screw hole 33 is provided on the inner wall of the arc-shaped groove 28 for threading with the fastening screw 32.

[0043] Working principle of this embodiment two:

[0044] In the stowed state, under the tension of the tension spring 27, the sliding plate 25 is pulled and stowed inside the guide groove 23. At this time, the top of the inclined guide plate 26 passes through the clearance groove 20 and is stowed inside the mounting cylinder 3. The ball head 14 is placed on the surface of the extension plate 21, and the inclined guide plate 26 is pressed against the ball head 14. The two buoyancy parts 15 are close to each other, and the energy-saving motor 2 is stowed inside the mounting cylinder 3, which reduces the footprint of the overall device and makes it easy to carry.

[0045] In the unfolded state, pulling the ring handle 17 upwards causes the lifting plate 10 on the energy-saving motor 2 to slide upwards along the lifting groove 16 on the inner wall of the mounting cylinder 3. During this process, the bushing 7 slides upwards along the drive shaft 8 (the drive shaft 8 always rotates with the rotation of the bushing 7). As the energy-saving motor 2 rises, it drives the ball head 14 to slide along the inclined guide plate 26, thereby squeezing the inclined guide plate 26 and forcing it to drive the slide plate 25 to slide away from the mounting cylinder 3 along the inner wall of the guide groove 23. The tension spring 27 is stretched, realizing the synchronous unfolding of the buoyancy part 15 and improving the floating performance of the entire device. When the extension rod 13 slides upwards along the clearance groove 20 to above the arc groove 28, the arc baffle 30 is pulled along the arc groove 28 until the fastening screw 32 is coaxial with the screw hole 33. The fastening screw 32 is tightened so that it is screwed into the screw hole 33. The arc baffle 30 is placed below the extension rod 13, and at the same time, the extension rod 13 is in contact with the top of the clearance groove 20 to prevent the extension rod 13 from moving and improve the stability of the entire device in the unfolded state. Example

[0050] The outer periphery of the sealing cover 49 is evenly provided with several heat conduction grooves 50; a lifting ring 51 coaxial with the sealing cover 49 is provided on the outside of the sealing cover 49; the lifting ring 51 has a hollow structure inside and several water outlet holes are evenly provided on its inner wall; a sponge ring 52 is fixed on the inner wall of the lifting ring 51; an extension tube 53 is symmetrically connected to the outer wall of the lifting ring 51; and a slide rail 54 that slides and engages with the slide groove 48 is symmetrically fixed on the outer wall of the lifting ring 51.

[0052] The water outlet pipe is connected to the external delivery pipe via a flexible hose. One-way valves are installed on the water outlet pipe, water inlet pipe, liquid extraction pipe 58, and liquid discharge pipe 59. By installing a one-way valve on the water outlet pipe, the water inside the sealing cover 49 can only be discharged to the external delivery pipe through the water outlet pipe.

By installing a one-way valve on the liquid discharge pipe 59, the water inside the piston tube 57 can only be discharged through the liquid discharge pipe 59 and then sent into the lifting ring 51 through the corresponding flexible hose and extension pipe 53 in sequence to moisten the sponge ring 52.

[0053] Working principle of this embodiment three:

[0054] During the deployment process, the buoyancy unit 15 drives the piston plate 40 to slide along the inner wall of the piston cylinder 41 away from the emergency pump 1, drawing water into the piston cylinder 41. The motor body 6 is then activated to draw water into the pump body 4 and discharge it through the drain pipe 43, the corresponding hose, and the vortex pipe 45 in sequence. This increases the weight of the overall device, lowers the center of gravity of the overall device, and further improves the stability of the overall device operation.

[0055] After the energy-saving flood control and emergency pump is deployed, the stability of the overall device operation can be further improved by tightening the pull rope 36 and inserting the fixing anchor 37 into the ground.

[0056] The water drawn out by the pump body 4 enters the sealing cover 49 through the branch pipe and is then discharged, which improves the heat exchange effect between the sealing cover 49 and the motor body 6. During operation, the motor body 6 drives the bushing 7 to rotate. Through the cooperation of the guide ball 62 and the threaded groove 60, the wet sponge ring 52 is driven to scrape back and forth along the outer wall of the sealing cover 49, which further improves the heat exchange effect between the sealing cover 49 and the motor body 6, thereby increasing the service life of the motor body 6.
