[0002] Submersible axial flow pumps are typically installed in rivers, reservoirs, or large containers filled with water. They use a rotating impeller to draw water in and discharge it to the outside, and are used to lift or discharge large amounts of water. Submersible axial flow pumps achieve drainage and irrigation functions by drawing water from a low place to a high place. The position of the impeller from the suction inlet affects the flow rate and head of the submersible axial flow pump.

[0016] Preferably, the bottom output end of the motor is connected to the lead screw located on the left side of the straw.

[0017] The inside of the support lug has a through hole;

[0018] A fixed rod is installed at the bottom of the side rod, and the fixed rod is connected to the connecting rod.

[0019] Preferably, a hook is installed on the outer side of the axial flow pump body, and positioning rods are installed on both sides of the axial flow pump body.

[0022] Preferably, an adjustment component is provided at the bottom of the rotating shaft, the adjustment component being used to adjust the height of the impeller;

[0024] Preferably, the submersible axial flow pump is used as follows:

[0025] Step 1: First, the operator needs to place the axial flow pump at the work site using the support legs, immerse the suction pipe and axial flow pump body in water, and power on the control module. Then, use the fixing parts to connect the drain pipe to the discharge pipe from the flange.

[0026] Step 2: Next, the staff will power on the drive unit set in the control module and transmit the start signal to the motor set in the drive unit. After receiving the start signal, the motor set in the drive unit will start under the support of the connecting parts. After the motor starts, it will drive the execution unit to rotate under the support of the shaft seal. At the same time, the execution unit will drive the impeller seat to rotate inside the axial flow pump body.

[0027] The coupling in the actuator receives the rotational power of the motor and drives the shaft to rotate under the action of the rotational power, which in turn drives the impeller seat to rotate together. Subsequently, after receiving the rotational power, the impeller seat drives the impeller to rotate through the support column.

[0028] Step 3: When it is necessary to adjust the flow rate and head, the operator needs to operate the adjustment component to adjust the height of the impeller set in the adjustment component. By adjusting the height, the flow rate and head of the axial flow pump can be adjusted.

[0029] Step 4: While adjusting the impeller height, the operator can start the motor to drive the lead screw to rotate and adjust the height of the adjustment component, so that the impeller is electrically adjusted to the appropriate height, saving manpower.

[0030] Step 5: Next, place the filter screen outside the suction tube and support feet using the support ring and the C rod and hook, and make the bottom ring contact the working area. Use the positioning and limiting effect of the arc sleeve and the three-shaped feet to provide positioning support for the filter screen, so that the filter screen can block impurities in the water.

[0031] Step 6: Then operate the reinforcement component to connect the magnet and threaded cone in the reinforcement component to the work site as needed, so that the reinforcement component can support and reinforce the axial flow pump body and prevent the axial flow pump body from tipping over.

[0032] Preferably, step 2 further includes the following steps:

[0033] Step 21: When it is necessary to adjust the height of the impeller, the operator can control the extension of the electric rod in the adjustment component under the support of the rotating shaft. The electric rod pushes the connecting shaft downward. The connecting shaft is cut from the rotating shaft. At the same time, the connecting shaft will drive the ring cylinder to move together. Under the guidance of the ring cylinder and the ring groove, the connecting shaft pushes the impeller seat downward, and the impeller seat pushes the impeller to move downward, thereby realizing the function of adjusting the height of the impeller.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. This invention, by installing an adjustment component, allows operators to control the support rod in the adjustment component to push the connecting rod downward along the movable hole according to actual needs. This causes the bearing two to move the support column downward under the action of external force, and the auxiliary blade moves downward together, thereby moving the impeller downward to a suitable height. The flow rate and head are simultaneously affected when the impeller moves, allowing operators to easily adjust the flow rate and head of the submersible axial flow pump by adjusting the height of the impeller.

[0036] 2. With the installation of a chassis, the present invention allows the operator to start the motor under the support of the axial flow pump body when the impeller height needs to be adjusted. This causes the lead screw to rotate under the support of the chassis, and at the same time, the lead screw drives the pulley installed on its outer side to rotate, transmitting the rotational power to the belt. This causes all pulleys, the lead screw, and the support rod to rotate, and the adjusting ring to move the adjusting components downward under the action of external force, thereby achieving the function of automatically adjusting the impeller height and saving manpower.

[0037] 3. This invention, by installing a hook, allows the liquid to pass through the filter screen and enter the inner side of the suction pipe when the submersible axial flow pump starts to draw water. At the same time, impurities in the liquid are intercepted by the filter screen, which bends to create an arc to trap the impurities. After the work is completed, the operator pulls the elastic rope through the support ring, causing the support ring and the elastic rope to move out from the inside of the hook. Then, the support ring is moved downward while the bottom ring is pulled upward, causing the filter screen to fold and wrap the impurities trapped on the outside. Finally, the bottom ring and support ring are pulled upward, allowing the bottom ring, support ring, and filter screen to pass through the axial flow pump body, pipe, and motor to be removed and disposed of outside. This achieves the goal of filtering impurities while conveniently handling the trapped impurities.

[0038] 4. This invention, with its reinforced components, allows workers to pull a handle while the pump is installed in a metal container. This releases the magnetic plate from the positioning rod, eliminating its magnetic attraction. The turntable is then pushed downwards to attract the magnet to the bottom of the metal container, providing support for the legs. When the pump is installed in a reservoir, the handle is turned to allow the threaded cone to penetrate the fixed hole and connect to the reservoir bottom threadedly using rotational power and thread action. This causes the pressure plate to press down on the legs, providing stable support and increasing the support width, thus preventing the pump from tipping over and improving stability.

[0056] The execution unit includes a coupling 11 located at the bottom output end of the motor 12, and a shaft seal 13 located inside the bushing 9. A rotating shaft 14 is installed at the bottom of the coupling 11, and the rotating shaft 14 passes through the inner side of the connecting sleeve 10 and the shaft seal 13 and connects to the top of the impeller seat 15 in the adjustment assembly.

[0057] The coupling 11 can transmit rotational power to the rotating shaft 14 under the drive of the drive unit. At the same time, the shaft seal 13 can provide rotational support for the rotating shaft 14 under the support of the shaft sleeve 9, and at the same time play a sealing role to prevent water inside the drain pipe 7 from leaking through the shaft sleeve 9. The rotating shaft 14 will drive the impeller seat 15 to rotate together. The impeller seat 15 will drive the guide vane 16 and use the guide vane 16 to drive the auxiliary vane 28 to rotate together. The auxiliary vane 28 and the support column 19 cooperate to drive the impeller 20 to rotate together. The impeller 20 uses rotational power to draw water into the inner side of the axial flow pump body 1 through the suction pipe 2 and discharge the liquid to the outside through the drain pipe 7.

[0058] Please see Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7This invention provides an embodiment of a high-efficiency, energy-saving submersible axial flow pump with an adjustable impeller and its usage method. The pump includes an adjustment assembly comprising a rotating shaft 14 disposed inside the pump body 1, an impeller seat 15 mounted at the bottom of the rotating shaft 14, a guide vane 16 mounted on the outer side of the impeller seat 15, an inner groove 17 at the bottom of the impeller seat 15, a guide groove 18 at the bottom of the guide vane 16, a support column 19 mounted inside the inner groove 17, an impeller 20 mounted at the bottom of the support column 19, a suction pipe 2 mounted at the bottom of the pump body 1, movable holes 21 penetrating through both sides of the suction pipe 2, a bearing 22 mounted on the outer side of the support column 19, side rods 23 mounted on both sides of the bearing 22, a connecting rod 24 mounted at the bottom of the side rods 23, and the connecting rod 24 being located at the impeller 20. On both sides, a support rod 26 is installed on the side of the connecting rod 24 away from the impeller 20. Multiple auxiliary blades 28 are installed on the outer side of the support rod 19, and the auxiliary blades 28 are located on the inner side of the guide groove 18. A rubber pad 27 is installed on the end of the auxiliary blade 28 away from the support rod 19, and the rubber pad 27 is in contact with the guide blade 16. A fixed rod 25 is installed at the bottom of the side rod 23, and the fixed rod 25 is connected to the connecting rod 24. The impeller seat 15 can provide opening space for the inner groove 17 under the support of the rotating shaft 14, and can stably support the guide blade 16. The guide blade 16 can provide a guiding function for the liquid. In cooperation with the impeller 20, the liquid can pass through the axial flow pump body 1 and flow into the inner side of the drain pipe 7. The guide blade 16 can provide opening space for the guide groove 18, and the guide groove 18 can provide a moving guiding function for the auxiliary blades 28.

[0059] According to the actual needs, the staff can control the support rod 26 to push the connecting rod 24 downward along the movable hole 21. Under the action of external force, the connecting rod 24 drives the side rod 23 to move downward. The side rod 23, with the reinforcement of the fixed rod 25, drives the bearing 22 to move downward together. At the same time, the bearing 22 can provide rotational support for the support column 19. Under the action of external force, the bearing 22 will drive the support column 19 to move downward along the inner groove 17. At the same time, the support column 19 will drive the auxiliary blade 28 to move downward along the guide groove 18. Thus, the support column 19 can drive the impeller 20 to move downward to a suitable height. When the impeller 20 moves, it will affect the flow rate and head simultaneously, so that the staff can easily adjust the flow rate and head of the submersible axial flow pump by adjusting the height of the impeller 20.

[0060] Please see Figure 1 , Figure 3 and Figure 7This invention provides an embodiment of a high-efficiency, energy-saving submersible axial flow pump with an adjustable impeller and its usage method. The pump includes a chassis 3. Two lead screws 30 are mounted on the top of the chassis 3 via bearings, located on both sides of a suction pipe 2. Two support rods 31 are also mounted on the top of the chassis 3 via bearings, located on the front and back of the suction pipe 2. Pulleys 32 are mounted on the outer sides of the lead screws 30 and support rods 31. A belt 63 is connected to the outer sides of the pulleys 32 and fitted onto them. The outer side of the axial flow pump body 1 is equipped with... There is a motor 33, the bottom output end of the motor 33 is connected to the lead screw 30, the outer thread of the lead screw 30 is fitted with an adjusting ring 29, and the adjusting ring 29 is connected to the support rod 26. The bottom output end of the motor 33 is connected to the lead screw 30 located on the left side of the suction tube 2. The chassis 3 can provide rotational support for the lead screw 30 through the bearing under the support of the suction tube 2, and can also provide rotational support for the frame rod 31 using the bearing. The belt 63 can transmit power to all pulleys 32, so that all pulleys 32 can rotate synchronously.

[0061] When the height of the impeller 20 needs to be adjusted, the operator can start the motor 33 with the support of the axial flow pump body 1. The motor 33 drives the lead screw 30 to rotate with the bearing mounted on its outer side as the center under the support of the chassis 3. At the same time, the lead screw 30 drives the pulley 32 mounted on its outer side to rotate and transmits the rotational power to the belt 63. The belt 63 drives all the pulleys 32, the lead screw 30 and the support rod 31 to rotate. At the same time, the lead screw 30 uses the rotational power and the thread to push the adjusting ring 29 to move downward. Under the action of external force, the adjusting ring 29 drives the adjusting component to move downward together, thereby realizing the automatic adjustment of the height of the impeller 20 and saving manpower.

[0062] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 8This invention provides an embodiment of a high-efficiency, energy-saving submersible axial flow pump with an adjustable impeller and its usage method. The pump includes an axial flow pump body 1, a hook 34 mounted on the outer side of the pump body 1, positioning rods 35 mounted on both sides of the pump body 1, a C-rod 36 mounted on the end of the positioning rods 35 away from the pump body 1, a support ring 37 placed inside the hooks 34 and C-rod 36, an elastic rope 38 threaded through the support ring 37, a filter screen 39 mounted at the bottom of the support ring 37, and the filter screen 39 located outside the suction pipe 2 and the support leg 4. A bottom ring 40 is mounted at the bottom of the filter screen 39. An elastic band 41 is installed through the interior of the axial flow pump body 1, which can provide stable support for the hook 34. The hook 34 is used to provide placement support for the support ring 37, and the axial flow pump body 1 can provide stable support for the positioning rod 35. The positioning rod 35 can provide support for the C rod 36. The C rod 36 and the hook 34 cooperate to provide positioning support for the support ring 37, so that the support ring 37 can stably support the filter screen 39. The bottom ring 40 can provide support for the bottom of the filter screen 39, and can cooperate with the support ring 37 to position the shape of the filter screen 39, so that the filter screen 39 can cover the outside of the straw 2 and the support leg 4.

[0063] When the submersible axial flow pump starts to draw water, the liquid passes through the filter screen 39 and enters the inside of the suction pipe 2. Simultaneously, impurities in the liquid are intercepted by the filter screen 39, preventing them from entering the inside of the suction pipe 2 and damaging the impeller 20. The filter screen 39 also bends and deforms towards the central axis of the suction pipe 2, using the resulting curvature to trap impurities. After work is completed, the operator can pull the support ring 37 in both the front and back directions, stretching the elastic rope 38. At this time, the support ring 37 will move out from the inside of the C rod 36. Then, slightly pull the support ring 37 upwards, causing it to pull the elastic rope 38 out from the inside of the hook 34. Then move the support ring 37 downwards while simultaneously lifting the bottom ring 40 upwards, so that the bottom ring 40 fits snugly against the support ring 37. At this point, the filter screen 39 will fold to wrap the impurities trapped on the outside. Then, the operator can pull the bottom ring 40 and the support ring 37 upwards. During the pulling process, the bottom ring 40 and the support ring 37 can be pulled to the front and back, causing the support ring 37 to stretch the elastic rope 38 and the bottom ring 40 to stretch the elastic band 41. This allows the bottom ring 40, the support ring 37, and the filter screen 39 to pass through the axial flow pump body 1, the pipe 7, and the motor 12 and be taken out to the outside for dumping and processing of impurities. This achieves the goal of conveniently processing the intercepted impurities while filtering them.

[0065] The reinforcing assembly includes an arc sleeve 42 installed through the inside of a bottom ring 40. Two support legs 4 near the arc sleeve 42 are fitted with geometric feet 43 on their outer sides, with the arc sleeve 42 fitted over the geometric feet 43. A through hole 44 is provided at the top of each geometric foot 43, and a positioning rod 45 is installed through the through hole 44. A magnet 46 is installed at the bottom of the positioning rod 45, and a turntable 47 is installed at the top of the positioning rod 45. A handle 48 is installed at the top of the turntable 47. An insertion hole 49 is provided on the side of the geometric foot 43 away from the arc sleeve 42, and the insertion hole 49 is connected to the through hole 44. An insertion rod 50 is placed through the insertion hole 49, and an arc magnetic plate 51 is installed at the end of the insertion rod 50 near the positioning rod 45. The arc magnetic plate 51 is attracted to the outside of the positioning rod 45 by the magnet 46. A pull handle 52 is installed on the outside of the insertion rod 50. A fixing hole 53 is provided at the bottom of the geometric foot 43, and a fixing hole 53 is provided on the side of the geometric foot 43 away from the arc sleeve 42. A side rod 54 is installed on the surface, and a threaded rod 55 is installed inside the side rod 54 through the thread. A pressure plate 56 is installed on the outside of the threaded rod 55. A threaded cone 57 is installed at the bottom of the threaded rod 55, and a handle 58 is installed at the top of the threaded rod 55. The bottom ring 40 can provide stable support for the arc sleeve 42. When the bottom ring 40 moves, it will drive the arc sleeve 42 to move together. The arc sleeve 42 can be engaged with the jig foot 43, so that the jig foot 43 can provide positioning and support for the bottom ring 40 through the arc sleeve 42 under the support of the support foot 4. The jig foot 43 can provide opening space for the through hole 44, the insertion hole 49 and the fixing hole 53. The through hole 44 can provide a through channel for the positioning rod 45. The positioning rod 45 can provide support for the magnet 46. The magnet 46 can be attracted to the bottom of the metal container. The fixing hole 53 can provide a through channel for the threaded cone 57. The threaded cone 57 and the threaded rod 55 have threads on their outer sides.

[0066] When the submersible axial flow pump is installed in the metal container, the operator can pull the handle 52 away from the suction tube 2 with the support of the feet 43. The handle 52 will drive the insertion rod 50 to move along the insertion hole 49. At the same time, the insertion rod 50 will cause the arc magnetic plate 51 to separate from the positioning rod 45 under the action of external force, releasing the magnetic attraction and fixation of the positioning rod 45. Then, the operator can hold the handle 48 and push the turntable 47 downward. Under the action of external force, the turntable 47 will push the positioning rod 45 to move downward along the through hole 44. Under the action of external force, the positioning rod 45 will push the magnet 46 downward and firmly attract it to the bottom of the metal container. The magnet 46, the positioning rod 45 and the feet 43 will cooperate to provide support and fixation for the support feet 4 and the chassis 3.

[0067] When the submersible axial flow pump is installed in the reservoir, the handle 58 can be pushed to rotate the threaded rod 55. The threaded rod 55 uses rotational power and the threaded action with the side rod 54 to push the threaded cone 57 and the pressure plate 56 downwards. The threaded cone 57 penetrates the solid hole 53 and contacts the bottom of the reservoir. The rotational power and the threaded action connect the threaded cone 57 to the bottom of the reservoir. The pressure plate 56 also pushes the support feet 43 downwards, so that the support feet 43 can be firmly connected to the bottom of the reservoir, providing stable support for the support feet 4. The support feet 43 increase the support width, thereby preventing the submersible axial flow pump from tipping over and improving stability.

[0068] Please see Figure 1 and Figure 6 The present invention provides an embodiment of a high-efficiency and energy-saving submersible axial flow pump with adjustable impeller and its usage method, including a rotating shaft 14, an adjustment component provided at the bottom of the rotating shaft 14, the adjustment component being used to adjust the height of the impeller 20;

[0069] The adjustment assembly includes an electric rod 59 embedded in the bottom of a rotating shaft 14. The bottom of the rotating shaft 14 has an annular groove 60. A connecting shaft 62 is installed at the bottom of the electric rod 59. An annular cylinder 61 is installed at the top of the connecting shaft 62 and is located inside the annular groove 60. An impeller seat 15 is installed at the bottom of the connecting shaft 62, and an impeller 20 is installed at the bottom of the impeller seat 15. The rotating shaft 14 can provide stable support for the electric rod 59 and provide space for the annular groove 60. The annular groove 60 can provide a moving guide for the annular cylinder 61. The annular cylinder 61 and the electric rod 59 cooperate to provide stable support for the impeller 20 and can rotate together with the rotating shaft 14.

[0070] According to the actual needs, the staff can control the electric rod 59 to extend under the support of the rotating shaft 14, so that the electric rod 59 pushes the connecting shaft 62 downward under the support of the rotating shaft 14. Under the action of external force, the connecting shaft 62 will drive the ring cylinder 61 to move downward along the ring groove 60. In this way, the connecting shaft 62 can push the impeller 20 downward to adjust the height under the guidance of the ring groove 60 and the ring cylinder 61, thus providing convenience for adjusting the height of the impeller 20.

[0071] Furthermore, the usage method of the submersible axial flow pump is as follows:

[0072] Step 1: First, the staff needs to place the axial flow pump at the work site using the support foot 4, immerse the suction pipe 2 and the axial flow pump body 1 in water, and power on the control module. Then, use the fixing parts to connect the drain pipe to the drain pipe 7 from the flange 8.

[0073] Step 2: Then, the staff will power on the drive unit set in the control module and transmit the start signal to the motor 12 set in the drive unit. After receiving the start signal, the motor 12 set in the drive unit will start under the support of the connecting parts. After the motor 12 starts, it will drive the execution unit to rotate under the support of the shaft seal 13. At the same time, the execution unit will drive the impeller seat 15 to rotate inside the axial flow pump body 1.

[0074] The coupling 11 in the execution unit receives the rotational power of the motor 12 and drives the rotating shaft 14 to rotate under the action of the rotational power, so that the rotating shaft 14 drives the impeller seat 15 to rotate together. Then, after receiving the rotational power, the impeller seat 15 drives the impeller 20 to rotate through the support column 19.

[0075] Step 3: When it is necessary to adjust the flow rate and head, the operator needs to operate the adjustment component to adjust the height of the impeller 20 set in the adjustment component. By adjusting the height, the flow rate and head of the axial flow pump can be adjusted.

[0076] Step 4: While adjusting the height of the impeller 20, the operator can start the motor 33, which will drive the lead screw 30 to rotate and adjust the height of the adjustment component, so that the impeller 20 is electrically adjusted to the appropriate height, saving manpower.

[0077] Step 5: Then, place the filter screen 39 outside the straw 2 and the support leg 4 with the support ring 37 under the support of the C rod 36 and the hook 34, and make the bottom ring 40 contact the working place. The positioning and limiting effect of the arc sleeve 42 and the geometric foot 43 provides positioning support for the filter screen 39, so that the filter screen 39 can block impurities in the water.

[0078] Step 6: Then operate the reinforcement component to connect the magnet 46 and threaded cone 57 in the reinforcement component to the work site as needed, so that the reinforcement component can support and reinforce the axial flow pump body 1 and prevent the axial flow pump body 1 from tipping over.

[0079] Furthermore, step 2 also includes the following steps:

[0080] Step 21: When it is necessary to adjust the height of the impeller 20, the operator can control the electric rod 59 in the adjustment assembly to extend under the support of the rotating shaft 14, so that the electric rod 59 pushes the connecting shaft 62 downward. The connecting shaft 62 is cut from the rotating shaft 14. At the same time, the connecting shaft 62 will drive the ring cylinder 61 to move together, so that the connecting shaft 62 pushes the impeller seat 15 downward under the guidance of the ring cylinder 61 and the ring groove 60, so that the impeller seat 15 pushes the impeller 20 downward, thereby realizing the function of adjusting the height of the impeller 20.

[0081] Working Principle: Before using the submersible axial flow pump, it is necessary to check whether there are any problems that may affect its use. When the operator needs to use the submersible axial flow pump, it should first determine whether the submersible axial flow pump is installed in a metal container or in a reservoir or other water. When installed in a metal container, the submersible axial flow pump is positioned and supported by magnets 46 under the support of the type 43. When installed in a reservoir or other water, the submersible axial flow pump is positioned and supported by threaded cones 57 under the support of the type 43. At the same time, the drainage pipe is connected to the drain pipe 7 through the fixing parts and flange 8. Then, the filter screen 39 is installed for protection using C rod 36, hook 34 and support ring 37, and under the positioning and restriction of the arc sleeve 42 by the type 43. Finally, the motor 12 is started to make the impeller 20 rotate and discharge water from the right side of the drain pipe 7 to the outside. Finally, it is determined whether the head and flow rate need to be adjusted. The motor 33 is started and the adjustment component is operated through the adjustment ring 29 to adjust the height of the impeller 20 to control the head and flow rate.
