[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Example: Refer to Figure 1-Figure 12A light and highly mobile flood fighting and rescue pump comprises a double pump group, the double pump group comprises a siphon pump group and a centrifugal pump group, after the centrifugal pump group draws the flood water into the siphon pump group, the siphon pump group draws the flood water out and discharges it, wherein the siphon pump comprises a pump body 10, a one-way valve is arranged at both the water inlet end and the water discharge end of the pump body 10, a mounting groove 11 is arranged at the top of the pump body 10, a water inlet joint 23 connected with the inner cavity of the pump body 10 is fixedly installed in the mounting groove 11, a water inlet pipe 41 is fixedly installed on the water inlet joint 23, a third drainage pipe 30 for drainage is fixedly installed at the water inlet end of the water inlet pipe 41, a first one-way control valve 31 is arranged on the third drainage pipe 30; The centrifugal pump group includes a first mounting cylinder 13 fixedly installed in the mounting groove 11, a second mounting cavity 16 is opened in the first mounting cylinder 13, a first drainage pipe 20 for connecting the inner cavity of the pump body 10 with the second mounting cavity 16 is fixedly installed at the bottom of the first mounting cylinder 13, a water-pumping turbine 19 is rotatably arranged in the second mounting cavity 16, a driving part for driving the water-pumping turbine 19 to rotate is arranged on the first mounting cylinder 13, a second drainage pipe 21 is fixedly installed on the top of the first mounting cylinder 13, a first one-way valve 22 is arranged on the second drainage pipe 21, and also includes a drone 1, a clamping bracket is arranged at the bottom of the drone 1, and the pump body 10 and the water inlet filter head are detachably connected to the clamping bracket.

[0021] In this embodiment, the functional component adopts a battery, which is fixedly installed in the installation groove 11 to provide energy for the driving part.

[0022] When in use, the drainage hose is fixed on the second drainage pipe 21 and the third drainage pipe 30, and the pump body 10 is fixed on the drone 1, and then the drone 1 is moved to the top of the river channel for collecting and discharging flood water, and then the drone 1 lowers its altitude so that one end of the drainage hose falls into the river channel, and then the pump body 10 is transported to the designated flood control and rescue location by the drone 1, and then the drone 1 is separated from the pump body 10, and the drone 1 is raised again. During the ascent of the drone 1, the water inlet filter head is carried up, and during this process, the water inlet pipe 41 originally folded and stored in the installation groove 11 is pulled open, and then the water inlet filter head is dropped into the flood, so as to quickly complete the placement and installation of the pump body 10, greatly improve the efficiency of flood control and rescue, reduce the burden on disaster relief personnel, and reduce the risk of disaster relief personnel installing flood control and rescue pumps.

[0023] When pumping water, the drive unit is started to drive the pumping turbine 19 to rotate. The pumping turbine 19 pumps flood water into the pump body 10 through the water inlet filter head and the water inlet pipe 41. During this process, the first one-way control valve 31 is closed until the pump body 10 is filled with water and the water is discharged from the second drain pipe 21. Then the first one-way control valve 31 is opened. Under the principle of the one-way valve and siphon, the water inside the pump body 10 flows to the second drain pipe 21 while being discharged. At the same time, it will also flow out through the third drain pipe 30, and then the flood water will be discharged into the river through the hose connected to the third drain pipe 30.

[0024] To sum up, in this embodiment, on the one hand, the battery drives the motor 14 to rotate and pump water, and there is no need to use engines such as oil extraction machines and gasoline engines, thereby reducing the overall weight of the flood control and rescue pump. Then, the pump body 10 is transported and installed by the drone 1, and the laying of the water inlet pipe 41 and the drainage pipe is completed by the drone 1, which greatly improves the maneuverability and flexibility in complex terrain and emergency situations, and reduces the time and risk of ground transportation and manpower handling; the flood is first initially pumped into the siphon pump group by the centrifugal pump group, and then the siphon pump group is used for efficient drainage. The combined use of the two pumps greatly improves the efficiency of flood extraction. In addition, after the energy carried by the flood control and rescue pump is exhausted, the siphon principle can still be used to continuously extract and discharge the flood, thereby improving the durability and reliability of flood control and rescue.

[0025] Reference Figure 7 The driving part includes a motor 14 fixedly mounted on the first mounting tube 13, and a mounting shaft 17 is fixedly mounted on the output end of the motor 14. The mounting shaft 17 extends into the second mounting cavity 16 and is fixedly connected to a water pumping turbine 19. The motor 14 is started, and the motor 14 drives the mounting shaft 17 to rotate, and the mounting shaft 17 drives the water pumping turbine 19 to rotate, thereby generating negative pressure inside the pump body 10, and the negative pressure is used to pump water.

[0026] Reference Fig.12 The water inlet pipe 41 includes an air storage outer tube 411, a water passing inner tube 412 and a connecting strip 413. The air storage outer tube 411 is sleeved on the water passing inner tube 412. The two sides of the connecting strip 413 are fixedly connected to the inner wall of the air storage outer tube 411 and the outer wall of the water passing inner tube 412 respectively. When the water inlet filter head is placed in water, air is inflated into the air storage outer tube 411. After the air storage outer tube 411 is expanded, the inner cavity of the water passing inner tube 412 is pulled open.

[0027] In this embodiment, when in use, that is, after the water inlet pipe 41 is laid, the outer air storage tube 411 is inflated to expand. When the outer air storage tube 411 expands, the inner hole of the water-passing inner tube 412 is opened through the connecting strip 413 to facilitate flood water to enter the interior of the pump body 10 through the water-passing inner tube 412.

[0028] When not in use, that is, when the water inlet pipe 41 is not completely laid, the air in the air storage outer pipe 411 and the water in the water passing inner pipe 412 are emptied, and then the water inlet pipe 41 is folded up, and then the folded part of the water inlet pipe 41 is placed in the installation groove 11, so as to facilitate transportation along with the flood fighting and rescue pump. In addition, the discharge pipe used to discharge flood water into the drainage channel can also be folded and placed in the installation groove 11.

[0030] In this embodiment, the installation shaft 17 can also drive the first fan blade 18 to rotate while rotating. The first fan blade 18 rotates to absorb external air, and then discharges it into the first outer tube 25 through the first air pipe 27, thereby expanding the air storage outer tube 411.

[0031] Reference Figure 1 and Figure 10-11 The water inlet filter head includes a counterweight block 37, a vertical pipe 39 is fixedly installed on the counterweight block 37, a second inner pipe 40 is fixedly installed on the side wall of the vertical pipe 39, a second outer pipe 45 is fixedly installed on the outer wall of the second inner pipe 40, a filter screen 42 is fixedly installed in the vertical pipe 39, an air storage outer pipe 411 at the water inlet end of the water inlet pipe 41 is fixedly connected to the second outer pipe 45, and a water-passing inner pipe 412 at the water inlet end of the water inlet pipe 41 is fixedly connected to the second inner pipe 40, an air cavity 26 is opened in the counterweight block 37, an exhaust hole 28 connected to the air cavity 26 is opened at the top of the counterweight block 37, an exhaust pipe 43 is fixedly installed at the bottom of the second outer pipe 45, a second one-way control valve 44 is fixedly installed on the exhaust pipe 43, and the second one-way control valve 44 is connected to the air cavity 26.

[0032] In this embodiment, the counterweight block 37 is used to ensure that the water inlet of the water inlet pipe 41 is submerged in water. When the water inlet pipe 41 expands, the second one-way control valve 44 is closed. When water enters the pump body 10, the second one-way control valve 44 is opened, and excess gas enters the air cavity 26 and is then discharged through the exhaust hole 28. The discharged gas generates bubbles in the water and moves upward. In this process, impurities in the water can be pushed away, thereby preventing the impurities from clogging the filter 42.

[0033] Reference Figure 4-Figure 8 A mounting box 32 is fixedly mounted on the third drain pipe 30, a second mounting cylinder 35 is fixedly mounted on the side wall of the mounting box 32, a rotating shaft 33 is rotatably connected inside the mounting box 32, an impeller 34 is fixedly connected to the rotating shaft 33, the rotating shaft 33 extends to the second mounting cylinder 35 and is fixedly connected to a second fan blade 36, a second air pipe 29 is fixedly connected to the exhaust end of the second mounting cylinder 35, the second air pipe 29 is connected to the first air pipe 27, and both the first air pipe 27 and the second air pipe 29 are provided with a one-way valve for intake of air into the first outer tube 25.

[0034] In this embodiment, the water discharged by the siphon pump drives the impeller 34 to rotate when passing through the installation box 32, the impeller 34 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the second fan blade 36 to rotate to supply air to the air storage outer tube 411. When the motor 14 stops working, the air cavity 26 continues to be inflated to ensure that the debris in the water is expelled during the siphon process.

[0035] Compared with the above embodiment, further, a rotor power generation device can be installed on the side wall of the installation box 32 to fix the rotor to the rotating shaft 33. Then, during the siphon drainage process, the kinetic energy generated by the flood discharge can be used to generate electricity, thereby improving the endurance of the motor 14.

[0036] Reference Figure 1-Figure 4 The clamping bracket includes a connecting rod 2 fixedly installed at the bottom of the drone 1, a mounting rod 3 is fixedly installed at the bottom of the connecting rod 2, a clamping plate 12 is fixedly installed on the top of the side wall of the pump body 10, and the clamping plate 12 is clamped on the mounting rod 3; two mounting rods 3 are provided, and also include a first electric telescopic cylinder 4 and a second electric telescopic cylinder 6, and the two extension rods of the first electric telescopic cylinder 4 are fixedly installed with a first connecting ring 5, and the first connecting ring 5 is rotatably connected to the mounting rod 3, and a visual camera is fixedly installed on the cylinder body of the first electric telescopic cylinder 4; the two extension rods of the second electric telescopic cylinder 6 are fixed A second connecting ring 7 is fixedly installed, and the second connecting ring 7 is rotatably connected to the mounting rod 3. A connecting plate 8 is fixedly installed on the two extending rods of the second electric telescopic cylinder 6, and an insert rod 9 is fixedly connected to the connecting plate 8. A hanging ring 38 is fixedly connected to the counterweight block 37, and the insert rod 9 is inserted into the hanging ring 38; when the extending rods of the first electric telescopic cylinder 4 and the second electric telescopic cylinder 6 extend one length unit (three to five centimeters), the mounting groove 11 is separated from the mounting bracket, and when the extending rods of the first electric telescopic cylinder 4 and the second electric telescopic cylinder 6 extend two length units, the water inlet filter head is separated from the insert rod 9.

[0037] When the drone 1 carrying the pump body 10 moves to a position where the body can be prevented, the extension rod of the second electric telescopic cylinder 6 extends one length unit, thereby disengaging the clamping plate 12 from the mounting rod 3. Then the drone 1 takes off again, moves the water inlet filter head above the flood, and extends the extension rod of the second electric telescopic cylinder 6 by one length unit, disengaging the water inlet filter head from the insertion rod 9, thereby causing the water inlet filter head to fall into the flood, automatically completing the laying of the water inlet pipe 41, allowing rescue personnel to stay away from the flood when installing the emergency pump, thereby reducing the risk of disaster relief.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
