Description

Technical Field

[0001] This invention relates to the field of axial flow pump technology, and particularly to a horizontal axial flow pump. Background Technology

[0002] An axial flow pump is a machine that relies on the rotation of an impeller to generate axial thrust to transport fluids. It is widely used in water intake, drainage, irrigation, municipal engineering and other fields.

[0003] Currently, most conventional axial flow pumps are vertical structures, which limits their installation methods. They require the construction of a special installation platform with a water tank underneath. The impeller of the axial flow pump must be submerged in the water tank to achieve normal fluid transport operations.

[0004] In outdoor scenarios without fixed platforms, such as riverbanks or shorelines, conventional vertical axial flow pumps cannot be installed and used due to the inability to construct dedicated installation platforms and supporting water tanks. This makes it difficult to meet the water intake and drainage needs in such scenarios, resulting in a significant application gap. Currently, there is no axial flow pump structure that can adapt to platform-less shoreline scenarios and achieve stable installation and operation without the need for a supporting water tank.

[0005] Therefore, a horizontal axial flow pump is provided to address the above problems. Summary of the Invention

[0017] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0018] The positive and progressive effects of this invention are as follows: The aforementioned horizontal axial flow pump features a horizontal design, allowing the base to be directly fixed to the ground near riverbanks or shorelines without the need for a dedicated installation platform. This makes installation convenient, quick, and less expensive than conventional vertical axial flow pumps. Furthermore, unlike existing vertical designs, it eliminates the need for a water tank, making it suitable for outdoor locations without fixed platforms, such as riverbanks or shorelines. This effectively meets the water intake and drainage needs in these environments, significantly improving the equipment's adaptability and ease of use.

[0019] Furthermore, it is equipped with a tilting mechanism and an inlet pipe telescopic adjustment structure. The tilting mechanism, through the meshing transmission of a worm gear and a worm wheel, can drive the inlet pipe to tilt downwards at different angles, achieving preliminary adjustment of the height of the inlet pipe end. Simultaneously, the inlet pipe consists of an inner pipe and a sleeve, which, in conjunction with the length adjustment mechanism, can achieve telescopic adjustment. The length adjustment mechanism is linked to the tilting mechanism; rotating the worm gear synchronously drives the inlet pipe to tilt and extend, requiring no additional operation. Through the synergistic effect of tilting and telescopic adjustment, the impeller can be adjusted to different water depths, significantly expanding the applicable range of water intake and drainage depths for the equipment, and flexibly adapting to different water depth usage scenarios.

[0020] An oil injection mechanism is mounted on the side shaft of the tilting mechanism, and this mechanism is linked to the pressing mechanism. The pressing mechanism is connected to a handwheel via a connecting strip. Pulling the handwheel drives the pressing mechanism to compress the oil injection mechanism, allowing lubricating oil to be delivered through channels and oil outlets to the bearing connection between the side shaft and the fixed seat for lubrication. Releasing the handwheel allows the oil injection mechanism to automatically draw oil from the oil tank for replenishment. This design effectively reduces wear between the side shaft and the fixed seat, extends service life, and provides convenient lubrication operation—simply pulling the handwheel is sufficient.

[0021] By concentrating the water inlet pipe tilting adjustment, telescopic adjustment, and side shaft lubrication operation into a single handwheel, the system eliminates the need for multiple separate operation points, thus providing greater convenience for overall use.

Detailed Implementation

[0024] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0025] like Figures 1-15As shown, a horizontal axial flow pump includes a base 1 and a pump body. The pump body includes an outlet pipe 2 fixed to the base 1. One end of the outlet pipe 2 is connected to an inlet pipe 4 via a corrugated hose 3. An impeller 7 is installed in the end of the inlet pipe 4 away from the corrugated hose 3.

[0026] The pump body is provided with a pump shaft 14, and the two ends of the pump shaft 14 are rotatably installed with the inlet pipe 4 and the outlet pipe 2 respectively; one end of the pump shaft 14 is connected to the output shaft of the motor 6 fixed on the base 1, and the other end of the pump shaft 14 is fixed to the impeller 7; a universal joint 1402 located in the corrugated hose 3 is provided in the middle of the pump shaft 14.

[0027] The water outlet pipe 2 is connected to a flipping mechanism 9.

[0028] In practical implementation, the entire horizontal axial flow pump is designed to be horizontal, directly fixed to the riverbank or shore via the base 1, with the inlet pipe 4 extending above the water surface (initial state, such as...). Figures 1-3 As shown, the inlet pipe 4 is horizontally positioned. The flipping mechanism 9 drives the inlet pipe 4 to flip downwards, causing the end of the inlet pipe 4 away from the corrugated hose 3 to enter the water and immerse the impeller 7 in the water. Figure 15 As shown, the motor 6 then drives the pump shaft 14 to rotate, the pump shaft 14 drives the impeller 7 to rotate, the impeller 7 drives the water to enter the inlet pipe 4, and then enters the outlet pipe 2 through the corrugated hose 3, and is discharged outward from the outlet pipe 2.

[0029] The above design, unlike the vertical design used in existing technologies, is suitable for platform-free scenarios such as riverbanks and shores, meeting the water intake and drainage needs in such scenarios, and eliminating the need for a water tank, making it convenient for use in these environments.

[0030] The flipping mechanism 9 allows the water inlet pipe 4 to be flipped downwards at different angles, making it easy to adjust the end of the water inlet pipe 4 away from the corrugated hose 3 to different height positions, so as to be suitable for water intake and drainage in different water depth environments.

[0031] The base 1 has multiple mounting holes 101. The mounting holes 101 provide mounting positions, and the pump can be fixed to the ground on the shore by expansion bolts or anchor bolts. There is no need to build a special installation platform, making installation convenient and quick, and the installation cost is lower than that of conventional vertical axial flow pumps.

[0032] like Figure 1 , Figure 2 , Figure 8 , Figure 9 as well as Figure 10As shown, the flipping mechanism 9 includes a sleeve 901 mounted on the water inlet pipe 4. Side shafts 902 are fixed on both sides of the sleeve 901. The side shafts 902 are rotatably connected to the fixed seat 8 fixed on the base 1. A worm gear 903 is fixedly sleeved on the side shaft 902. The worm gear 903 meshes with a worm 904. The worm 904 is rotatably connected to the bracket 905 fixed on the fixed seat 8.

[0033] By rotating the worm 904, the worm 904 meshes with the worm wheel 903, causing the side shaft 902 to rotate. The side shaft 902 drives the sleeve 901 and the water inlet pipe 4 to rotate together, realizing the tilting adjustment of the water inlet pipe 4. At the same time, through the self-locking between the worm 904 and the worm wheel 903, the adjusted angle can be maintained after tilting adjustment.

[0034] like Figure 1 , Figure 5 as well as Figure 7 As shown, the water inlet pipe 4 includes an inner pipe 401 that is fixedly connected to the end of the corrugated hose 3 and a sleeve 402 that is sleeved on the inner pipe 401. The sleeve 901 is fixedly sleeved on the inner pipe 401. A sealing ring 403 is fixedly sleeved on the outer wall of the end of the inner pipe 401 away from the corrugated hose 3. The sealing ring 403 is tightly fitted to the inner wall of the sleeve 402. The water inlet pipe 4 is connected to an adjusting mechanism 5, and the adjusting mechanism 5 is connected to a driving mechanism 10. The driving mechanism 10 is connected to a worm gear 904.

[0035] Through the above design, the inlet pipe 4 can also be extended and retracted. When the worm gear 904 is rotated to flip the inlet pipe 4 downwards, the worm gear 904 drives the drive mechanism 10 to operate. The drive mechanism 10 drives the lengthening mechanism 5, which extends the inlet pipe 4. Compared with only setting the flipping mechanism 9, the end of the inlet pipe 4 away from the corrugated hose 3 can be adjusted to a lower position, increasing the applicable range of water intake depth. At the same time, driving the inlet pipe 4 to flip and extend / retract only requires rotating the worm gear 904, without any other additional operations, and will not increase the labor intensity of the operator.

[0036] like Figure 3 , Figure 4 , Figure 5 as well as Figure 7As shown, the length adjustment mechanism 5 includes a connecting seat 504 fixed on the inner tube 401. The connecting seat 504 is fixed with a first cylinder 501. A first piston 505 is fitted inside the first cylinder 501. A first stopper rod 502 is fixed to the first piston 505. The first stopper rod 502 is slidably fitted with one end of the first cylinder 501, and the end of the first stopper rod 502 away from the first piston 505 extends to the outside of the first cylinder 501. The end of the first stopper rod 502 away from the first piston 505 is fixed to the outer wall of the sleeve 402 through an end bracket 503. One end of the first cylinder 501 is fixedly connected to a diversion pipe 12, and the diversion pipe 12 is fixedly connected to a spiral hose 13 located below the corrugated hose 3. The spiral hose 13 is connected to the drive mechanism 10.

[0037] like Figures 8-10 As shown, the drive mechanism 10 includes a stud 1001 fixed to one end of a worm gear 904; the end of the stud 1001 away from the worm gear 904 is rotatably connected to an end seat 1003 fixed on a base 1; a nut seat 1002 is threaded onto the stud 1001; a connecting plate 1005 is fixed to the nut seat 1002; a second stopper rod 1006 is fixed to the connecting plate 1005; a second cylinder 1007 is fixed to the base 1; the second stopper rod 1006 is slidably sleeved with the second cylinder 1007; a second piston 1008 is fixed to one end of the second stopper rod 1006; the second piston 1008 cooperates with the second cylinder 1007; a connecting pipe 1004 is fixedly connected to one end of the second cylinder 1007; and the connecting pipe 1004 is fixedly connected to a spiral hose 13.

[0038] When the worm gear 904 is rotated, causing the flipping mechanism 9 to drive the outlet pipe 2 to flip downwards, the stud 1001 rotates together with the worm gear 904. Through the threaded transmission between the stud 1001 and the nut seat 1002, the sliding between the second plug rod 1006 and the second cylinder 1007 provides guidance, causing the nut seat 1002 to move closer to the end seat 1003. The nut seat 1002 drives the second plug rod 1006 and the second piston 1008 to move together through the connecting plate 1005. The second piston 1008 pushes the medium (hydraulic oil or gas) in the second cylinder 1007, causing the medium to enter the first cylinder 501 in sequence through the connecting pipe 1004, the spiral hose 13 and the diverting pipe 12. Then the medium pushes the first piston 505 and the first plug rod 502 to move together, causing the first plug rod 502 to extend out of the first cylinder 501. The lengthening mechanism 5 extends as a whole, and the first plug rod 502 drives the sleeve 402 to move, causing the inlet pipe 4 to extend as a whole.

[0039] Reverse rotation of the worm gear 904 causes the flipping mechanism 9 to drive the outlet pipe 2 to flip upward. When it returns to horizontal, the stud 1001 rotates with the worm gear 904, driving the nut seat 1002 to move closer to the bracket 905. The nut seat 1002 drives the second plug rod 1006 to move outward from the second cylinder 1007. The second piston 1008 causes the second cylinder 1007 to be sucked up, so that the medium in the first cylinder 501 returns to the second cylinder 1007 in sequence through the diversion pipe 12, the spiral hose 13 and the connecting pipe 1004. This causes the length adjustment mechanism 5 to retract as a whole, and in turn, causes the inlet pipe 4 to retract as a whole, reducing the storage volume of the horizontal axial flow pump.

[0040] like Figures 5-6 As shown, the pump shaft 14 includes a first shaft body 1401; one end of the first shaft body 1401 is fixed to the output shaft of the motor 6, and the other end of the first shaft body 1401 is connected to a second shaft body 1403 through a universal joint 1402. A square groove 1406 is provided at the center of the second shaft body 1403, and a square shaft 1405 is slidably fitted in the square groove 1406. A connecting shaft 1404 is fixed to the square shaft 1405. The connecting shaft 1404 is fixed to the impeller 7. The connecting shaft 1404 is rotatably connected to a mounting bracket 1407 fixed in the sleeve 402. The second shaft body 1403 is rotatably connected to the mounting bracket 1407 fixed in the inner tube 401. The first shaft body 1401 is rotatably connected to the mounting bracket 1407 fixed in the outlet pipe 2.

[0041] The universal joint 1402 is used to accommodate the flipping of the water inlet pipe 4. When the water inlet pipe 4 is flipped, the water inlet pipe 4 and the pump shaft 14 part located in the water inlet pipe 4 flip together. The sliding of the square shaft 1405 and the square groove 1406 is used to accommodate the extension and retraction of the water inlet pipe 4.

[0042] In order to enable the water inlet pipe 4 to bend downwards and flip over, the weight of the water inlet pipe 4 and the structure above it is applied to the fixed base 8 through the side shaft 902. There is a large pressure between the side shaft 902 and the fixed base 8, resulting in significant wear between them. To reduce wear, the following design is implemented.

[0043] like Figures 9-10 As shown, an oil injection mechanism 16 is installed on the side shaft 902, and the oil injection mechanism 16 is connected to a pushing mechanism 11; a connecting strip 1107 is fixed to the input end of the pushing mechanism 11, a handwheel 15 is rotatably installed on the connecting strip 1107, a square rod 1502 is coaxially fixed to the handwheel 15, and a sleeve 1501 is fixed to one end of the stud 1001, and the inner wall of the sleeve 1501 slides with the square rod 1502.

[0044] The handwheel 15 is used to rotate the stud 1001 and the worm gear 904, while the square rod 1502 and the sleeve 1501 are provided so that the handwheel 15 can be pulled. When the handwheel 15 is pulled and moved, the handwheel 15 drives the pushing mechanism 11 through the connecting bar 1107. The pushing mechanism 11 drives the oiling mechanism 16 to inject oil into the side shaft 902, thereby providing lubrication for the connection between the side shaft 902 and the fixed seat 8.

[0045] In summary, the water inlet pipe 4 can be bent, flipped, and extended / retracted by operating the handwheel 15, and the oiling mechanism 16 can be driven to provide oil lubrication between the side shaft 902 and the fixed seat 8; the operation parts are concentrated in the handwheel 15, making it convenient for operators to operate.

[0046] like Figure 13 As shown, the oil injection mechanism 16 includes a fixed frame 1602 fixed on a fixed base 8; an oil cylinder 1601 is fixed on the fixed frame 1602, a third piston 1604 is fitted inside the oil cylinder 1601, a pressure-bearing column 1603 is fixed to the third piston 1604, a second spring 1605 is provided inside the oil cylinder 1601, and the two ends of the second spring 1605 abut against the inner end faces of the third piston 1604 and the oil cylinder 1601 respectively; one end of the oil cylinder 1601 is fixedly connected to an oil outlet 1606 and an oil inlet 1607, and a first one-way valve 1608 and a second one-way valve 1609 are fixed inside the oil outlet 1606 and the oil inlet 1607 respectively; the oil inlet 1607 is connected to an oil tank provided on the base 1 through a pipe, and the oil outlet 1606 is connected to a side shaft 902 on the sleeve 901.

[0047] like Figure 13 As shown, the sleeve 901 has a channel 9011 inside, and the channel 9011 extends into the side shaft 902. A circular insertion port 9022 is provided at the center of the end of the side shaft 902 on one side of the sleeve 901 (the side shaft 902 on the other side does not have an insertion port 9022), and the insertion port 9022 communicates with the channel 9011. The insertion port 9022 is inserted into the oil outlet 1606, and a sealing gasket 9023 is provided inside the insertion port 9022. Several oil outlet holes 9021 are provided on the cylindrical surface of the side shaft 902 in a ring array. A bearing 801 is provided in the fixed seat 8. The inner ring of the bearing 801 is fixed to the side shaft 902, and a connecting hole 802 communicating with the oil outlet hole 9021 is provided on the inner ring of the bearing 801.

[0048] The circular design of the socket 9022, and the matching shape of the oil outlet 1606 with the socket 9022, ensures that the rotation of the side shaft 902 is not affected. A sealing gasket 9023 provides a seal at the connection between the socket 9022 and the oil outlet 1606, ensuring that the lubricating oil discharged from the oil outlet 1606 enters the channel 9011 through the socket 9022 without leakage.

[0049] like Figure 9 and Figure 12 As shown, the pushing mechanism 11 includes a first guide seat 1101 and a second guide seat 1102. Both the first guide seat 1101 and the second guide seat 1102 are fixed to the base 1, and both the first guide seat 1101 and the second guide seat 1102 have guide holes. A movable rod 1103 is slidably fitted into the guide holes. One end of the movable rod 1103 is fixed to a connecting strip 1107, and the other end of the movable rod 1103 is fixed to an end block 1104. The end block 1104 is also fixed with... The extrusion plate 1105 has a first spring 1106 sleeved on the movable rod 1103. The movable rod 1103 is elastically connected to the second guide seat 1102 through the first spring 1106. One side of the extrusion plate 1105 abuts against the end of the pressure column 1603. The side wall of the extrusion plate 1105 is provided with a first vertical surface 11051 and a second vertical surface 11052, and an inclined surface 11053 is provided between the first vertical surface 11051 and the second vertical surface 11052.

[0050] When handwheel 15 is not pulled, such as Figure 12 As shown, the extrusion plate 1105 is attached to the pressure column 1603 through its second vertical surface 11052.

[0051] When the handwheel 15 is pulled, the handwheel 15 drives the movable rod 1103 to move together through the connecting bar 1107 and compress the first spring 1106. The movable rod 1103 drives the pressing plate 1105 to move through the end block 1104 until the first vertical surface 11051 abuts against the pressure column 1603. During the above process, the pressure column 1603 is pressed by the inclined surface 11053, causing it to move into the oil cylinder 1601. The pressure column 1603 drives the third piston 1604 to push the oil in the oil cylinder 1601 and compress the second spring 1605. The oil enters the socket 9022 through the oil outlet 1606 and the first one-way valve 1608, then enters the channel 9011, and then is discharged into the bearing 801 from the oil outlet 9021 and the connecting hole 802, providing lubrication for the bearing 801.

[0052] When the handwheel 15 is released, the elastic force of the first spring 1106 resets the movable rod 1103, connecting bar 1107, handwheel 15, and pressing plate 1105, causing the second vertical surface 11052 to move back to the pressure column 1603. Meanwhile, in the oil injection mechanism 16, the elastic force of the second spring 1605 moves the third piston 1604 and the pressure column 1603. The pressure column 1603 moves outward from the oil cylinder 1601 and remains in contact with the pressing plate 1105. The oil cylinder 1601 draws in oil to replenish the oil needed for the next lubrication. Specifically, the oil in the oil tank on the base 1 enters the oil cylinder 1601 through the pipe, the oil inlet 1607, and the second one-way valve 1609.

[0053] With the above design, lubrication of the bearing 801 between the side shaft 902 and the fixed seat 8 can be achieved by pulling and releasing the handwheel 15, making the lubrication operation convenient.

[0054] The water outlet pipe 2 is connected to multiple connecting pipes 17. The multiple connecting pipes 17 are spliced ​​together to form pipes of different lengths. The end of the spliced ​​pipe that is away from the water outlet pipe 2 is connected to a sprinkler pipe 18. Multiple sprinkler heads 1801 are provided on the sprinkler pipe 18.

[0055] Different numbers of connecting pipes 17 are used to assemble pipe bodies of different lengths for conveying water over different distances. After the entire horizontal axial flow pump draws water, the water is conveyed through the connecting pipes 17 into the sprinkler pipe 18, and then sprayed out from multiple nozzles 1801, forming fine water droplets that are evenly sprinkled to irrigate the plants, thus achieving water-saving irrigation.

The protection scope of this invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications fall within the protection scope of this invention.
