DETAILED DESCRIPTION

[0042] The following description is used to disclose the present application so that those skilled in the art can implement the present application. The preferred embodiments in the following description are only as examples, and other obvious modifications can be conceived by those skilled in the art.

[0043] As Figures 1 to 11 shown in the figure, the intelligent height-adjustable flood control water pump includes a mounting seat 1, the bottom of the mounting seat 1 is fixedly connected with a protective cover 3, the bottom of the mounting seat 1 is liftably installed with a submersible pump body 17, the bottom of the submersible pump body 17 is fixedly connected with an impeller bin 9, the two sides of the impeller bin 9 are respectively communicated with a water inlet pipe 21 and a water outlet pipe 26, the water inlet pipe 21 is communicated with a filter assembly and an external pipe 19, the filter assembly is arranged on the outside of the submersible pump body 17, the top of the mounting seat 1 is provided with a heat dissipation assembly, and the heat dissipation assembly is used for heat dissipation of the submersible pump body 17;

[0044] In the working process of the submersible pump body 17, when the submersible pump body 17 can completely immerse in water, the water inlet pipe 21 is communicated with the filter assembly, and the submersible pump body 17 is heat dissipated by the flow of water, when the submersible pump body 17 cannot completely immerse in water, the water inlet pipe 21 is communicated with the external pipe 19, and the heat dissipation assembly is opened, and the submersible pump body 17 is heat dissipated by the heat dissipation assembly.

[0045] In the specific implementation, first, the submersible pump body 17 is transported to the position required for drainage, then the submersible pump body 17 is controlled to descend, so that the impeller bin 9 sinks into the water bottom, and then the submersible pump body 17 is started to work for drainage.

[0046] When the submersible pump body 17 can be completely submerged in water, the water inlet pipe 21 and the filter assembly of the impeller chamber 9 are communicated, and the water flow drawn by the submersible pump body 17 is filtered by the filter assembly, which can prevent the impeller chamber 9 from being blocked by impurities in the water and can also use the water flow to cool the submersible pump body 17, thereby preventing the submersible pump body 17 from overheating.

[0047] When the submersible pump body 17 cannot be completely submerged in water, the water inlet pipe 21 and the filter assembly of the impeller chamber 9 are communicated, and the water flow drawn by the submersible pump body 17 is filtered by the filter assembly, which can prevent the impeller chamber 9 from being blocked by impurities in the water and can also use the water flow to cool the submersible pump body 17, thereby preventing the submersible pump body 17 from overheating.

[0048] The use range of the device can be effectively improved by the water inlet pipe 21, the filter assembly and the external pipe 19. When the device is used for drainage work in deep water such as a river or a reservoir, impurities such as waterweeds often exist in the water. The filter assembly can effectively prevent the waterweeds from adhering to the outside of the submersible pump body 17, thereby preventing the heat dissipation efficiency of the submersible pump body 17 from decreasing. When the device is used for drainage work in a shallow pit such as accumulated water formed in a transformer substation due to heavy rain, the wiring in the transformer substation is complex, so the accumulated water needs to be drained in time. The accumulated water is formed for a short time, so impurities such as waterweeds do not exist. At this time, the water inlet pipe 21 and the external pipe 19 are communicated to drain the accumulated water. During this process, the submersible pump body 17 cannot be completely submerged in water due to the different depths of the accumulated water. The heat dissipation assembly is turned on to cool the submersible pump body 17, thereby preventing the submersible pump body 17 from being burned out due to ineffective heat dissipation.

[0049] As a further embodiment of the present application, the filter assembly comprises a filter screen 25, the inner side of the filter screen 25 is fixedly connected with a plurality of triangular heat dissipation plates 23, the cross section of the triangular heat dissipation plate 23 is a right triangle, the hypotenuse thereof is fixedly connected with the filter screen 25, and one of the right angles is fixedly connected with the outer wall of the submersible pump body 17 to cool the submersible pump body 17. The outer side of the filter screen 25 is fixedly connected with a plurality of external heat dissipation plates 24, a plurality of filter holes are arranged on the filter screen 25, the filter holes are located between adjacent two external heat dissipation plates 24, and the bottom of the filter screen 25 is fixedly connected with a ring cavity 27 with a cross section of a "U" shape, the two side wall plates of the ring cavity 27 are fixedly connected with the bottom wall plate of the submersible pump body 17 and the bottom wall plate of the filter screen 25 respectively.

[0050] In the embodiment, when the submersible pump body 17 can be completely submerged in water to work, the water flow extracted by the submersible pump body 17 can pass through the triangular heat dissipation plate 23 and the filter screen 25 for filtration, and then the water flow can enter the space formed by the triangular heat dissipation plate 23, the filter screen 25 and the submersible pump body 17, and the submersible pump body 17 is cooled by the flow of the water flow. In the process of the flow of the water flow, the filter screen 25 can filter the impurities such as weeds in the water under the inertial action of the water flow, so as to avoid the impurities such as weeds from adhering to the filter screen 25. On the one hand, it is beneficial to avoid the weeds from adhering to the submersible pump body 17 to reduce the heat dissipation efficiency of the submersible pump body 17. On the other hand, the weeds can be prevented from blocking the filter screen 25 by the filtering method, so as to avoid the situation that the water pumping efficiency of the submersible pump body 17 is reduced.

[0051] By arranging the triangular heat dissipation plate 23, the heat generated by the submersible pump body 17 can be effectively conducted, so that the water flow can effectively take away the heat, and the heat can also be conducted to the external heat dissipation plate 24 through the filter screen 25. This is beneficial to expand the heat dissipation area of the submersible pump body 17, so that the heat can be lost faster. In addition, when the submersible pump body 17 cannot be completely submerged in water to work, the external heat dissipation plate 24, the filter screen 25 and the triangular heat dissipation plate 23 can also be used to effectively cool the submersible pump body 17 by the cooling assembly.

[0052] As a further embodiment of the present application, the cooling assembly comprises a fan 2 fixedly connected at the top center of the mounting seat 1. A ring groove 29 is arranged in the top wall plate of the mounting seat 1, and a plurality of air holes are arranged at the bottom of the ring groove 29. The output end of the fan 2 is communicated with a vertical pipe, and the side of the vertical pipe is communicated with a plurality of air outlet pipes 28. The ends of the air outlet pipes 28 away from the vertical pipe are communicated with the ring groove 29.

[0053] In the embodiment, when the submersible pump body 17 cannot be completely submerged in water to work, the fan 2 is started to blow air into the air outlet pipes 28 through the vertical pipe, and then the air is delivered into the ring groove 29. Finally, the air is blown into the inside of the protective cover 3 through the air holes, and then the air flow is blown onto the triangular heat dissipation plate 23, the filter screen 25 and the external heat dissipation plate 24 outside the submersible pump body 17 under the guidance of the protective cover 3. The heat dissipation of the submersible pump body 17 is realized by air cooling.

[0055] In specific implementation, in the process of the submersible pump body 17 working, the output shaft is driven to rotate by the submersible motor 18, and then the impeller is driven to rotate, and the water flow is extracted from the water inlet pipe 21 of the impeller chamber 9 through the rotation of the impeller in the impeller chamber 9.

[0056] In the process of extracting the water flow, when the submersible pump body 17 cannot be completely submerged in water to work, the electromagnetic three-way valve 20 communicates the external pipe 19 with the water inlet pipe 21, and when the submersible pump body 17 can be completely submerged in water to work, the electromagnetic three-way valve 20 communicates the water inlet pipe 21 and the communication pipe 22, so that the water inlet pipe 21 can extract the water flow from the ring cavity 27 through the communication pipe 22.

[0057] As a further embodiment of the present application, the bottom of the protective cover 3 is fixedly connected with a ring plate 4, a plurality of rectangular grooves are formed in the inside of the ring plate 4, a sliding column 32 is slidably connected in the rectangular groove, a damping spring 31 is fixedly connected to one end of the sliding column 32, the end of the damping spring 31 away from the sliding column 32 is fixedly connected to the inner wall of the rectangular groove, a cleaning inclined surface 35 is formed in the end of the sliding column 32 away from the damping spring 31, the cleaning inclined surface 35 is used for cleaning the part of the filter screen 25 between the two external heat dissipation plates 24, and a guide groove 33 is formed in the bottom of the end of the sliding column 32 away from the damping spring 31.

[0058] In specific implementation, after the submersible pump body 17 is completely submerged in water to work, the submersible pump body 17 is controlled to rise, so that the submersible pump body 17 can be stored in the protective cover 3, and the submersible pump body 17 is protected by the protective cover 3, in the process of the submersible pump body 17 rising, when the external heat dissipation plate 24 rises to the plane where the sliding column 32 is located, the guide groove 33 is in contact with the external heat dissipation plate 24, through the arrangement of the guide groove 33, the sliding column 32 can be located between the two external heat dissipation plates 24, with the movement of the submersible pump body 17, the cleaning inclined surface 35 at the end of the sliding column 32 can be in contact with the filter screen 25, so as to clean the surface of the filter screen 25, and at the same time, the two side wall plates at the end of the sliding column 32 clean the wall plates of the external heat dissipation plate 24, which is conducive to avoiding the situation that the external heat dissipation plate 24 cannot be effectively cooled due to the attachment of water plants on the surface of the external heat dissipation plate 24.

[0059] After the cleaning slope 35 at the end of the sliding column 32 cleans the filter screen 25, the fan 2 can be started, and the air blown out from the air hole can be used to clean the dust and impurities scraped off by the sliding column 32, so that the dust is blown off, and the water outside the submersible pump body 17 can also be dried by the air flow, which is beneficial to avoid the rust of the submersible pump body 17 caused by water stains outside the submersible pump body 17.

[0060] After the submersible pump body 17 is completely accommodated in the protective cover 3, the sliding column 32 abuts against the filter screen 25, and the damping spring 31 applies an elastic force to the sliding column 32. The damping spring 31 can effectively dampen and buffer the lateral movement of the submersible pump body 17 during movement, thereby reducing the impact on the submersible pump body 17 during movement.

[0062] In specific implementation, when the submersible pump body 17 cannot be completely submerged in water for work, the heat dissipation assembly is started to perform heat dissipation work on the submersible pump body 17. During the starting of the heat dissipation assembly, the memory bellows 5 is pulled downward to extend to the outside of the submersible pump body 17, so that the air blown out by the fan 2 can blow on the outside of the submersible pump body 17, thereby achieving the purpose of heat dissipation of the submersible pump body 17.

[0063] During the rising of the submersible pump body 17, the cross rod 16 located at the side of the abutting column 15 abuts against the bottom of the memory bellows 5. With the rising of the submersible pump body 17, the cross rod 16 also rises, and the memory bellows 5 is accommodated to the bottom of the protective cover 3 through the cross rod 16. After the submersible pump body 17 rises to the highest position, the abutting column 15 abuts against the ring plate 4, thereby achieving the effect of fixing the submersible pump body 17 and avoiding the shaking of the submersible pump body 17 during movement.

[0064] As a further embodiment of the present application, the air bag 14 is embedded at the bottom center of the bottom plate 6, and an air pump 34 is also embedded in the inside of the bottom plate 6, one end of the air pump 34 is communicated with the air bag 14, the other end of the air pump 34 is communicated with the rubber tube 8, the outer wall of the end of the rubber tube 8 away from the air pump 34 is fixedly connected with the foam plate 7, the end of the foam plate 7 away from the rubber tube 8 is fixedly connected with the arc-shaped tube, the arc-shaped tube is communicated with the end of the rubber tube 8 away from the air pump 34, and the outer wall of the ring plate 4 is also fixedly connected with the hook 13, and the hook 13 is used for suspending the arc-shaped tube.

[0065] In specific implementation, when the submersible pump body 17 works in deep water, the water resistance needs to be overcome in the process of recovering the submersible pump body 17, when the water resistance is large, the air pump 34 is started, the air pump 34 extracts air through the arc-shaped tube, and then the air bag 14 is inflated, after the air bag 14 is inflated, the displacement of the device is increased, and then the buoyancy of the device is increased, and the difficulty of recovering the device is reduced by increasing the buoyancy of the device.

[0066] Through the setting of the foam plate 7, the arc-shaped tube can always float on the water surface, which is beneficial to avoid the situation that the air pump 34 extracts water, after the submersible pump body 17 is accommodated in the protective cover 3, the rubber tube 8 is wound on the hook 13, and the arc-shaped tube is hung on the hook 13.

[0073] The controller 10 sends the generated control information to the winch 30 to control the winch 30 to stop working.

[0074] As a further embodiment of the application, the working method of the underwater distance sensor 11 during the process of the winch 30 lowering the submersible pump body 17 is specifically:

[0075] The underwater distance sensor 11 obtains distance information of itself and the water bottom;

[0077] The underwater distance sensor 11 sends the request information to the controller 10 to request the controller 10 to control the winch 30 to stop working;

[0078] The basis for generating the request information is specifically: when the distance information obtained by the underwater distance sensor 11 feedbacks a distance of zero, it means that the underwater distance sensor 11 has reached the water bottom, and at this time the underwater distance sensor 11 generates the request information.

[0079] In specific implementation, during the process of controlling the submersible pump body 17 to ascend and descend, when the submersible pump body 17 is lowered, the winch 30 is used to lower the submersible pump body 17, so that after the submersible pump body 17 is lowered below the water surface, the underwater distance sensor 11 obtains distance information of the bottom plate 6 and the water bottom, when the bottom plate 6 and the wall plate of the water bottom abut, the underwater distance sensor 11 generates the request information, and then the underwater distance sensor 11 sends the request information to the controller 10, the controller 10 sends control information to the winch 30, and after the winch 30 receives the control information, it stops working, so that the submersible pump body 17 hovers on the water bottom, the height of the submersible pump body 17 is adjusted through the winch 30 and the underwater distance sensor 11, so that the submersible pump body 17 can hover on the water bottom no matter what depth of water surface it faces.

[0080] Through the setting of the bottom plate 6, the submersible pump body 17 can be effectively separated from the silt of the water bottom, so as to avoid that the submersible pump body 17 sucks the silt of the water bottom during working.

[0081] The working principle of the application is:

[0082] In use, first, the device is transported to the position where drainage is needed by the external movable base, then the submersible pump body 17 is put into the water by controlling the winch 30, then the submersible motor 18 is started, the impeller is driven to rotate by the submersible motor 18, the water in the impeller chamber 9 is pumped through the water inlet pipe 21, then it is discharged through the water outlet pipe 26, the water flow pumped by the impeller chamber 9 can be discharged by adding a drain pipe on the water outlet pipe 26, so as to achieve the purpose of drainage, and the drain pipe is commonly known to those skilled in the art and will not be disclosed here.

[0083] During the operation of the submersible pump body 17, when the submersible pump body 17 works in deep water such as river channels and reservoirs, the water grass and other substances in the water of the river channel and the reservoir are filtered by the filter assembly, on the one hand, it can avoid the water grass entering the impeller chamber 9 and causing the impeller chamber 9 to be blocked, on the other hand, it can also avoid the water grass adhering to the outside of the submersible pump body 17 to cause the heat dissipation efficiency to be reduced, secondly, the bottom plate 6 can also block the water grass at the bottom of the river and the reservoir from entering the impeller chamber 9, further avoiding the water grass from being sucked into the impeller chamber 9 and causing the impeller chamber 9 to be blocked, and the bottom plate 6 can also block the silt at the bottom of the water from entering the impeller chamber 9, which is beneficial to avoid the silt from being sucked into the impeller chamber 9.

[0084] After the operation of the submersible pump body 17 is completed, the submersible pump body 17 is lifted by controlling the winch 30, and as the winch 30 rises, the cleaning slope 35 at the end of the sliding column 32 abuts against the filter screen 25 to scrape off the small amount of impurities on the surface of the filter screen 25. The setting of the triangular heat dissipation plate 23 and the filter screen 25 enables the filter screen 25 to push the water grass and other impurities away from the submersible pump body 17 under the action of water flow inertia when the water flows, thereby avoiding the water grass from being blocked on the filter screen 25.

[0085] The setting of the fan 2 can heat the submersible pump body 17 when the submersible pump body 17 cannot be completely immersed in water to work, and can also blow off the dust scraped off by the cleaning slope 35 after the cleaning of the filter screen 25, which is beneficial to avoid the dust from adhering to the outside of the submersible pump body 17 to cause the heat dissipation efficiency of the submersible pump body 17 to be reduced, secondly, the fan 2 can also blow dry the outer wall of the submersible pump body 17, which is beneficial to avoid the rust caused by the water stains adhering to the outer wall of the submersible pump body 17.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
