DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Fig.10 The low-noise, high-flow water pump based on the impeller structure comprises a base 1, a pump body 2 is fixedly connected to the upper end of the base 1, a water delivery cavity 3 is opened in the pump body 2, a water inlet pipe 4 is fixedly connected to the middle of the inner wall of the water delivery cavity 3, and a water outlet pipe 5 is fixedly connected to the top of the water delivery cavity 3 (such as Figure 2 as shown).

[0035] The inner wall of the water delivery cavity 3 is sealed and rotatably connected to a first rod 6, and the side wall of the first rod 6 located in the water delivery cavity 3 is fixedly connected to a rotating plate 7 (such as Figure 3 as shown).

[0036] The water pumping mechanism includes a cavity 8 opened in the rotating plate 7, and the side wall of the rotating plate 7 is sealed with four second rods 9 for rotation. The ends of the four second rods 9 away from the rotating plate 7 are fixedly connected to the impeller 10 (such as Figure 3 and Fig. 9 as shown).

[0037] The rotating plate 7 is provided with a first rotating mechanism, which includes a third rod 16 which is sealingly and rotatably connected to the side wall of the rotating plate 7, the side wall of the third rod 16 is rotatably connected to the side wall of the first rod 6, one end of the third rod 16 passes through the side wall of the rotating plate 7 and is located in the cavity 8, the side wall of the third rod 16 located in the cavity 8 is fixedly connected to the first helical gear ring 17 through a plurality of brackets, the ends of the four second rods 9 away from the impeller 10 all pass through the side wall of the rotating plate 7 and are fixedly connected to the first helical gear 18, and the side walls of the first helical gear ring 17 are all meshed with the side walls of the four first helical gears 18 (such as Figure 3 as shown).

[0038] When the third rod 16 rotates, the third rod 16 drives the first bevel gear ring 17 to rotate through multiple brackets, and then the first bevel gear ring 17 drives multiple second rods 9 to rotate through four first bevel gears 18, drives the four impellers 10 to rotate, and then adjusts the angles of the four impellers 10.

[0039] The side wall of the impeller 10 is provided with a fan-shaped cavity 11 (such as Figure 3 and Figure 4 As shown, the inner wall of the fan-shaped cavity 11 close to the second rod 9 is rotatably connected to two movable leaves 12 (as shown in FIG. Figure 3 and Figure 4 As shown), the inner wall of the fan-shaped cavity 11 is sealed and rotatably connected with a lead screw 13, the side wall of the lead screw 13 is threadedly connected with a slider 14, and the side wall of the slider 14 is rotatably connected to the side walls of the two movable leaves 12 through two rotating rods 15.

[0040] The upper end of the base 1 is fixedly connected to an L-shaped plate 19, and the side wall of the L-shaped plate 19 is provided with a second rotating mechanism, and the second rotating mechanism includes a fourth rod 20 rotatably connected to the side wall of the L-shaped plate 19, one end of the fourth rod 20 penetrates the side wall of the third rod 16 and extends into the cavity 8, and the side wall of the fourth rod 20 is rotatably connected to the side wall of the third rod 16, and the side wall of the fourth rod 20 located in the cavity 8 is fixedly connected to a second helical gear ring 21 through a plurality of brackets, and the ends of the four lead screws 13 close to each other respectively penetrate the side walls of the four second rods 9 (such as Figure 3 As shown), the side walls of the four lead screws 13 in the cavity 8 are fixedly connected to the second bevel gears 22, and the side walls of the second bevel gear ring 21 are meshed with the side walls of the four second bevel gears 22 (as shown Figure 3 as shown).

[0041] After adjusting the angles of the four impellers 10, the fourth rod 20 can be rotated clockwise or counterclockwise. At this time, the fourth rod 20 drives the second bevel gear ring 21 to rotate clockwise or counterclockwise through multiple brackets, and then the second bevel gear ring 21 drives the four lead screws 13 to rotate counterclockwise or clockwise through the four second bevel gears 22, driving the four sliders 14 to slide in a direction away from the second bevel gears 22 or in a direction close to the second bevel gears 22. At this time, the slider 14 will drive the two movable blades 12 to rotate outward or inward through the two rotating rods 15. At this time, the side area of ​​the impeller 10 can be adjusted.

[0042] In summary, the water pump can adjust the angles and side areas of the four impellers 10, which can not only make the angle of the impeller 10 consistent with the water flow angle to reduce noise, but also increase the side area of ​​the impeller 10 when the impeller 10 rotates to be tilted, increase the pumping amount of the water flow, and thus increase the water flow rate, thereby avoiding the situation in the prior art where the blades of the water pump are of a fixed shape, and the blade shape is designed based on the flow head calculation at the design point, but when the flow water deviates from the design point passes through the blades, the water flow angle and the blade angle are not consistent, which will cause noise, etc., and at this time, the water flow rate per unit time will also decrease.

[0043] A driving mechanism is provided on the base 1, and the driving mechanism includes two electric slide rails 26 fixedly connected to the upper end of the base 1, a slide plate 27 is commonly installed on the side walls of the two electric slide rails 26, a motor 28 is fixedly connected to the upper end of the slide plate 27, a first gear 23 is fixedly connected to the side wall of the first rod 6, a second gear 24 is fixedly connected to the side wall of the third rod 16, a third gear 25 is fixedly connected to the side wall of the fourth rod 20, and a fourth gear 29 is fixedly connected to the side wall of the output shaft of the motor 28. The fourth gear 29 is meshed with the first gear 23, the second gear 24 and the third gear 25 respectively during the movement.

[0044] The two electric slide rails 26 can drive the motor 28 to move horizontally through the slide plate 27, so that the fourth gear 29 can mesh with the first gear 23, the second gear 24 and the third gear 25 respectively during the movement, and then respectively drive the first rod 6, the third rod 16 and the fourth rod 20 to rotate. It should be noted that during the horizontal movement of the motor 28, the motor 28 rotates slowly at this time, and then the fourth gear 29 rotates slowly to approach the first gear 23, the second gear 24 and the third gear 25 respectively. Although during use, the fourth gear 29 may not be able to mesh with the side wall of the first gear 23, the second gear 24 or the third gear 25 at the first time, as the fourth gear 29 rotates slowly, the fourth gear 29 will mesh with the side wall of the first gear 23, the second gear 24 or the third gear 25 during the movement, and the whole process will not take too long and the operation is simple.

[0045] like Figure 6 As shown, the first rod 6 is provided with a first clamping mechanism, which includes a first annular groove 31 opened on the side wall of the first rod 6, a first T-shaped ring 30 is fixedly connected to the side wall of the third rod 16, the side wall of the first T-shaped ring 30 is sealed and slidably connected to the inner wall of the first annular groove 31, a plurality of first clamping grooves 33 are opened on the inner side wall of the first annular groove 31 near the first rod 6, a first annular cavity 32 is opened in the first T-shaped ring 30, and a first elastic membrane ring 34 is fixedly connected to the inner wall of the first annular cavity 32 near the first clamping groove 33.

[0046] After the hydraulic oil is pumped into the first annular cavity 32, the hydraulic oil will squeeze the first elastic membrane ring 34, causing the side wall of the first elastic membrane ring 34 facing the multiple first grooves 33 to deform. At this time, the deformed side wall of the first elastic membrane ring 34 will fit with the inner walls of the multiple first grooves 33. At this time, the rotation of the first rod 6 will drive the third rod 16 to rotate through the multiple first grooves 33, the first elastic membrane ring 34 and the first T-shaped ring 30. When the hydraulic oil in the first annular cavity 32 is extracted, the side wall of the first elastic membrane ring 34 will be completely separated from the inner walls of the multiple first grooves 33. At this time, the rotation of the first rod 6 will not drive the third rod 16 to rotate.

[0047] like Figure 7 As shown, the third rod 16 is provided with a second clamping mechanism, and the second clamping mechanism includes a second annular groove 39 opened on the side wall of the third rod 16, and a second T-ring 38 is fixedly connected to the side wall of the fourth rod 20, and the side wall of the second T-ring 38 is sealed and slidably connected to the inner wall of the second annular groove 39, and the second annular groove 39 is provided with a plurality of second clamping grooves 42 near the inner side wall of the third rod 16, and a second annular cavity 40 is opened in the second T-ring 38, and a second elastic membrane ring 41 is fixedly connected to the inner wall of the second annular cavity 40 near the second clamping groove 42.

[0048] After the hydraulic oil is pumped into the second annular cavity 40, the hydraulic oil will squeeze the second elastic membrane ring 41, causing the side wall of the second elastic membrane ring 41 facing the multiple second grooves 42 to deform. At this time, the deformed side wall of the second elastic membrane ring 41 will fit with the inner walls of the multiple second grooves 42. At this time, the rotation of the third rod 16 will drive the fourth rod 20 to rotate through the multiple second grooves 42, the second elastic membrane ring 41 and the second T-shaped ring 38. When the hydraulic oil in the second annular cavity 40 is extracted, the side wall of the second elastic membrane ring 41 will be completely separated from the inner walls of the multiple second grooves 42. At this time, the rotation of the third rod 16 will not drive the fourth rod 20 to rotate.

[0049] The side walls of the L-shaped plate 19 are fixedly connected to the vertical plates, and the side walls of the vertical plates are respectively fixedly connected to the first plate 35 and the second plate 43 (such as Figure 8As shown, the side wall of the first plate 35 is provided with a third annular groove 36, and the side wall of the first T-ring 30 away from the first rod 6 is sealed and slidably connected to the inner wall of the third annular groove 36 (as shown in FIG. Figure 6 As shown, the inner wall of the first annular cavity 32 is fixedly connected to a plurality of first tubes 37 (as shown in FIG. Figure 6 As shown in FIG. 3 ), the mouth of the first tube 37 is located in the third annular groove 36 .

[0050] A fourth annular groove 44 is formed on the side wall of the second plate 43, and a side wall of the second T-shaped ring 38 away from the third rod 16 is sealed and slidably connected to the inner wall of the fourth annular groove 44. A plurality of second tubes 45 (such as Figure 7 As shown in FIG. 4 ), the mouth of the second tube 45 is located in the fourth annular groove 44 .

[0051] The side wall of the pump body 2 is fixedly connected to the oil pump frame 46, and the inner wall of the oil pump frame 46 is sealed and slidably connected to the third plate 47. The side wall of the third plate 47 is fixedly connected to the upper end of the slide plate 27 through an L-shaped rod 48 (such as Figure 8 As shown, the top of the oil pump frame 46 is connected to the inner wall of the third annular groove 36 through the third pipe 49, and the top of the oil pump frame 46 is connected to the inner wall of the fourth annular groove 44 through the fourth pipe 50 (as shown in FIG. Figure 5 and Figure 8 as shown).

[0052] A first solenoid valve 51 (such as Figure 5 As shown, a second solenoid valve 52 is installed in the fourth pipe 50, and a first sensor 53 and a second sensor 54 are fixedly connected to the side walls of the vertical plate (as shown in FIG. Figure 8 and Fig.10 As shown in FIG. 1 ), the first sensor 53 is electrically connected to the first solenoid valve 51 through an external control mechanism, and the second sensor 54 is electrically connected to the second solenoid valve 52 through an external control mechanism.

[0053] When the motor 28 moves so that the fourth gear 29 meshes with the second gear 24, the first sensor 53 can sense the signal of the movement of the slide plate 27, and then the first solenoid valve 51 is powered on and opened through the external control mechanism. At this time, the third tube 49 is opened. At this time, the movement of the slide plate 27 drives the third plate 47 to slide through the L-shaped rod 48, so that the space in the oil pump frame 46 is increased, and then the oil pump frame 46 absorbs hydraulic oil from the first annular cavity 32 through the third tube 49, the third annular groove 36, and the plurality of first tubes 37, so that the side wall of the first elastic membrane ring 34 is completely separated from the inner walls of the plurality of first card grooves 33. Subsequently, the rotation of the third rod 16 will not drive the first rod 6 to rotate, but the rotation of the third rod 16 will drive the fourth rod 20 to rotate. At this time, the angle and side area of ​​the impeller 10 can be adjusted;

[0054] When the motor 28 continues to move and needs to make the fourth gear 29 mesh with the third gear 25, the second sensor 54 can sense the signal of the movement of the slide plate 27, and then the second solenoid valve 52 is powered on and opened through the external control mechanism, and the first solenoid valve 51 is still powered on and opened. At this time, the fourth pipe 50 is opened, and then the oil pump frame 46 draws hydraulic oil from the second annular cavity 40 through the fourth pipe 50, the fourth annular groove 44, and the plurality of second pipes 45, so that the side wall of the second elastic membrane ring 41 is completely separated from the inner walls of the plurality of second slots 42. Then, the rotation of the fourth rod 20 will not drive the third rod 16 to rotate. At this time, only the side area of ​​the impeller 10 is adjusted;

[0055] In this way, the third rod 16 and the fourth rod 20 can be driven to rotate respectively, so as to adjust the angles and side areas of the four impellers 10;

[0056] After subsequent adjustments, the motor 28 is driven to move to its original position by the two electric slide rails 26 and the slide plate 27. At this time, the fourth gear 29 is engaged with the first gear 23, and the third plate 47 moves to its original position. At this time, hydraulic oil is pumped into the first annular cavity 32 and the second annular cavity 40. At this time, the first rod 6, the third rod 16 and the fourth rod 20 form a whole. At the same time, the signals on the first sensor 53 and the second sensor 54 disappear, so that the first solenoid valve 51 and the second solenoid valve 52 are both powered off and closed, so that the third tube 49 and the fourth tube 50 are both closed.

[0057] During use of the water pump, the driving motor 28 rotates, and then the fourth gear 29 drives the first rod 6 to rotate through the first gear 23, and then the rotating plate 7 drives the multiple impellers 10 to rotate, and the water entering the water delivery chamber 3 from the water inlet pipe 4 is pumped out through the water outlet pipe 5;

[0058] When the water flow angle changes and the angle of the four impellers 10 needs to be adjusted, the driving motor 28 rotates slowly and drives the motor 28 to move horizontally through the two electric slide rails 26 and the slide plate 27, so that the fourth gear 29 is meshed with the second gear 24. During this process, the first sensor 53 can sense the signal of the movement of the slide plate 27, and then the first solenoid valve 51 is powered on and opened through the external control mechanism. At this time, the third tube 49 is opened. At this time, the movement of the slide plate 27 drives the third plate 47 to slide through the L-shaped rod 48, so that the space in the oil pump frame 46 is increased, and then the oil pump frame 46 absorbs hydraulic oil from the first annular cavity 32 through the third tube 49, the third annular groove 36, and the multiple first tubes 37, so that the side wall of the first elastic membrane ring 34 is completely separated from the inner wall of the multiple first card grooves 33, and then the rotation of the third rod 16 will not drive the first rod 6 to rotate;

[0059] Then the driving motor 28 rotates, and then the fourth gear 29 drives the third rod 16 to rotate through the second gear 24. At this time, the third rod 16 drives the first bevel gear ring 17 to rotate through multiple brackets, and then the first bevel gear ring 17 drives multiple second rods 9 to rotate through four first bevel gears 18, and drives the four impellers 10 to rotate, thereby adjusting the angles of the four impellers 10;

[0060] When the side area of ​​the impeller 10 needs to be adjusted later, the motor 28 continues to move so that the fourth gear 29 meshes with the third gear 25. At this time, the second sensor 54 can sense the signal of the movement of the slide plate 27, and then the second solenoid valve 52 is powered on and opened through the external control mechanism. At this time, the fourth pipe 50 is opened, and then the oil pump frame 46 draws hydraulic oil from the second annular cavity 40 through the fourth pipe 50, the fourth annular groove 44, and the plurality of second pipes 45, so that the side wall of the second elastic membrane ring 41 is completely separated from the inner walls of the plurality of second card grooves 42;

[0061] Then the driving motor 28 rotates counterclockwise or clockwise, at which time the fourth gear 29 drives the fourth rod 20 to rotate clockwise or counterclockwise through the third gear 25, at which time the fourth rod 20 drives the second bevel gear ring 21 to rotate clockwise or counterclockwise through multiple brackets, and then the second bevel gear ring 21 drives the four lead screws 13 to rotate counterclockwise or clockwise through the four second bevel gears 22, driving the four sliders 14 to slide away from the second bevel gear 22 or slide towards the second bevel gear 22, at which time the slider 14 will drive the two movable leaves 12 to rotate outward or inward through the two rotating rods 15, and the side area of ​​the impeller 10 can be adjusted at this time;

[0062] In this way, the water pump can adjust the angles and side surface areas of the four impellers 10, which can not only make the angle of the impeller 10 consistent with the water flow angle to reduce noise, but also increase the side surface area of ​​the impeller 10 when the impeller 10 rotates and tilts, increase the pumping amount of the water flow, and thus increase the water flow rate, thereby avoiding the problem that the blades of the water pump in the prior art are fixed in shape, and the blade shape is designed based on the flow head calculation of the design point. However, when the flow water at a flow rate deviating from the design point passes through the blade, the water flow angle and the blade angle are not consistent, which will cause noise, etc., and at this time, the water flow rate per unit time will also decrease;

[0063] After adjustment, the motor 28 is driven to move to the original position by the two electric slide rails 26 and the slide plate 27. At this time, the fourth gear 29 is meshed with the first gear 23, and the third plate 47 is moved to the original position. At this time, hydraulic oil is pumped into the first annular cavity 32 and the second annular cavity 40. At this time, the hydraulic oil will squeeze the first elastic membrane ring 34, so that the side wall of the first elastic membrane ring 34 facing the multiple first grooves 33 is deformed. At this time, the deformed side wall of the first elastic membrane ring 34 will fit with the inner walls of the multiple first grooves 33, and the hydraulic oil will squeeze the second elastic membrane ring 41. The side wall of the second elastic membrane ring 41 facing the multiple second slots 42 is deformed. At this time, the deformed side wall of the second elastic membrane ring 41 will fit with the inner walls of the multiple second slots 42, that is, the first rod 6, the third rod 16 and the fourth rod 20 form a whole. At the same time, the signals on the first sensor 53 and the second sensor 54 disappear, so that the first solenoid valve 51 and the second solenoid valve 52 are both powered off and closed, so that the third tube 49 and the fourth tube 50 are both closed. When the angle and side area of ​​the impeller 10 need to be adjusted again during subsequent use, the above steps can be repeated.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts 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.
