Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pumps, in particular to a novel impeller of a hydraulic pump. Background Technique

[0002] A hydraulic pump is a power component of a hydraulic system. It is driven by an engine or a motor, sucks oil from a hydraulic oil tank, forms pressurized oil and discharges it to an actuator. Since the suction force generated during the operation of the hydraulic pump is relatively strong, the hoses at the output end and the input end of the device need to withstand a strong impact force. To avoid the hoses from falling off after being impacted, a novel impeller of a hydraulic pump is required. Therefore, the existing novel impeller of a hydraulic pump has been continuously innovated and developed. It can be seen that the existing novel impeller of a hydraulic pump basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the publication number CN214154209U discloses a novel hydraulic pump housing, including a housing and a support body. The other end of the housing is fixedly connected with a first end cover. Through the setting of the limit posts, the novel hydraulic pump housing has the effect of fixing the limit blocks. Through the cooperation of the limit shaft and the fifth vertical plate, the limit shaft can slide along the fifth vertical plate during use, thus playing a role in opening and closing the first end cover, achieving the purpose of convenient disassembly. Through the setting of the connecting shaft and the first connecting cylinder, the novel hydraulic pump housing has the effect of fixing the electric telescopic rod. Through the cooperation of the electric telescopic rod, the first rotating shaft and the second rotating shaft, the mounting plate can rotate during use, thus playing a role in adjusting the angle and achieving the purpose of convenient installation. By setting the electric telescopic rod, the first rotating shaft and the second rotating shaft, the mounting plate can rotate during use, thus playing a role in adjusting the angle and achieving the purpose of convenient installation.

[0004] However, when the above device pumps liquid, it is difficult for the device to effectively fix the input end and the output end during the process of installing the hose for transporting the liquid to the input end and the output end of the device. Since the suction force generated during the operation of the hydraulic pump is relatively strong, the hose for transporting the liquid needs to withstand a strong impact force. This easily causes the hose to fall off after being subjected to a strong impact force, thus affecting the normal operation of the device. Therefore, a novel impeller of a hydraulic pump is urgently needed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a novel impeller of a hydraulic pump to solve the problem that the hoses at the input end and the output end of the device are prone to falling off after being impacted by water flow as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions, and discloses a new impeller of a hydraulic pump, including a housing, a servo motor is fixedly connected to the top of the housing, a connecting shaft is fixedly connected to the output end of the servo motor, and three groups of blades are fixedly connected to the surface of the connecting shaft;

[0007] A clamping mechanism, including a guide cylinder, one side of the guide cylinder is fixedly connected to one side of the housing, a connecting pipe is fixedly connected to the other side of the guide cylinder, connecting blocks are fixedly connected to both sides of the connecting pipe, a clamping plate is rotatably connected to the inner wall of the connecting block, a threaded sleeve rod is rotatably connected to the top of one side of the clamping plate, a threaded rod is threadedly connected to the inner wall of the threaded sleeve rod, a hand wheel is fixedly connected to one end of the threaded rod, and a limiting block is fixedly connected to the other side of the top of the clamping plate.

[0008] As a preferred technical solution of the present utility model, two groups of partition plates are fixedly connected to the inner side wall of the guide cylinder, and the two partition plates divide the guide cylinder into three spaces.

[0009] As a preferred technical solution of the present utility model, reinforcing blocks are fixedly connected to both sides of the guide cylinder, and one side of the reinforcing block is fixedly connected to both sides of the housing.

[0010] As a preferred technical solution of the present utility model, a protective box is fixedly connected to the top of the housing, and heat dissipation holes are opened on the top of the protective box.

[0011] As a preferred technical solution of the present utility model, support frames are fixedly connected to the four circumferences at the bottom of the housing, and a sealing ring is arranged on the inner wall of the housing.

[0012] As a preferred technical solution of the present utility model, the inner diameter of the inner wall of the clamping plate is greater than the outer diameter of the connecting pipe, and the clamping plate is located outside the connecting pipe.

[0013] As a preferred technical solution of the present utility model, communication grooves are opened on both sides of the housing, and the communication grooves are located on one side of the guide cylinder.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the liquid delivery hose is installed on the surface of the connecting pipe. Then, the clamping plate is rotated so that after rotation, the clamping plate is knotted to the surface of the liquid delivery hose. Next, one side of the handwheel is lapped on one side of the limit block and the handwheel is rotated, thereby driving the threaded rod to rotate. After the threaded rod is rotated into the threaded sleeve rod, the two clamping plates are driven to rotate relatively to clamp and fix the liquid delivery hose on the surface of the connecting pipe. The liquid delivery hose clamped by the clamping plate can be effectively fixed on the surface of the connecting pipe, thus avoiding the liquid delivery hose from falling off due to the impact of too fast liquid flow rate on the liquid delivery hose. Moreover, the clamping plate can be adjusted according to the diameter of the liquid delivery hose itself, enabling the device to fix liquid delivery hoses of various models, thereby improving the practicability of the device.

[0016] 2. In the present utility model, the guide cylinder is divided into three parts by multiple partition plates for transporting liquid. When reducing the flow space of the liquid, the flow rate in the guide cylinder becomes faster. And the multiple partition plates can also form a screening structure in the guide cylinder to prevent larger objects from being sucked into the housing and causing damage to the impeller, thereby extending the service life of the device.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 、 Figure 3 and Figure 4 A new impeller of a hydraulic pump: It includes a housing 1. A servo motor 2 is fixedly connected to the top of the housing 1. The output end of the servo motor 2 is fixedly connected to a connecting shaft 3. Three groups of blades 4 are fixedly connected to the surface of the connecting shaft 3;

[0025] A clamping mechanism, including a guiding cylinder 5. One side of the guiding cylinder 5 is fixedly connected to one side of the housing 1. The other side of the guiding cylinder 5 is fixedly connected to a connecting pipe 6. Connecting blocks 7 are fixedly connected to both sides of the connecting pipe 6. A clamping plate 8 is rotatably connected to the inner wall of the connecting block 7. A threaded sleeve rod 9 is rotatably connected to the top of one side of the clamping plate 8. A threaded rod 10 is threadedly connected to the inner wall of the threaded sleeve rod 9. One end of the threaded rod 10 is fixedly connected to a handwheel 11. A limiting block 12 is fixedly connected to the other side of the top of the clamping plate 8.

[0026] When using the new impeller of a hydraulic pump, first rotate the clamping plate 8 to open it, then insert one end of two groups of liquid delivery hoses respectively onto the surfaces of the two connecting pipes 6 on both sides of the housing 1, and then rotate the clamping plate 8 so that the clamping plate 8 rotates inside the inner wall of the connecting block 7. After rotating one side of the two clamping plates 8 to overlap on both sides of the liquid delivery hose, rotate the threaded sleeve rod 9. The rotation of the threaded sleeve rod 9 drives the threaded rod 10 and the handwheel 11 to move, so that one side of the handwheel 11 moves to one side of the limiting block 12, making the surface of the threaded rod 10 overlap on the top of the limiting block 12. Then rotate the handwheel 11. The rotation of the handwheel 11 drives the threaded rod 10 to rotate, so as to draw the threaded rod 10 into the threaded sleeve rod 9, making one side of the handwheel 11 squeeze one side of the limiting block 12, so that the threaded rod 10 and the threaded sleeve rod 9 drive the two clamping plates 8 to move relatively. After the clamping plates 8 move relatively, they clamp and fix both sides of the liquid delivery hose. After fixing the liquid delivery hose to the surface of the connecting pipe 6, place the liquid delivery hose into the liquid, connect the servo motor 2 to the power supply. The output end of the servo motor 2 drives the connecting shaft 3 to rotate. The rotation of the connecting shaft 3 drives the blades 4 on the surface to move around the axis of the connecting shaft 3, so as to pump the liquid into the liquid delivery hose, and then enter the connecting pipe 6, the guiding cylinder 5 and the housing 1 in sequence through the liquid delivery hose, and then be sent into another group of liquid delivery hoses through the guiding cylinder 5 and the connecting pipe 6 on the other side of the housing 1, so as to transport the liquid.

[0027] Please refer to Figure 2 and Figure 5 On the inner side wall of the guide cylinder 5, two groups of partition plates 13 are fixedly connected. The two groups of partition plates 13 divide the guide cylinder 5 into three spaces. Reinforcing blocks 14 are fixedly connected to both sides of the guide cylinder 5, and one side of the reinforcing block 14 is fixedly connected to both sides of the housing 1.

[0028] After the two groups of partition plates 13 arranged on the inner wall of the guide cylinder 5 divide the guide cylinder 5 into three spaces, the flow rate of the water flowing through the guide cylinder 5 becomes faster. And when pumping the liquid, the larger impurities in the liquid are blocked by one side of the partition plate 13, thereby preventing larger objects from being sucked into the guide cylinder 5.

[0029] Please refer to Figure 1 、 Figure 3 and Figure 4 On the top of the housing 1, a protective box 15 is fixedly connected. A heat dissipation hole 16 is opened on the top of the protective box 15. Support frames 17 are fixedly connected to the four surrounding parts at the bottom of the housing 1. A sealing ring 18 is arranged on the inner wall of the housing 1. The inner diameter of the inner wall of the clamping plate 8 is larger than the outer diameter of the connecting pipe 6. The clamping plate 8 is located outside the connecting pipe 6. Communication grooves 19 are opened on both sides of the housing 1, and the communication grooves 19 are located on one side of the guide cylinder 5.

[0030] The protective box 15 can protect the surface of the servo motor 2, and the heat dissipation hole 16 on the top of the protective box 15 can effectively discharge the heat generated when the servo motor 2 works. The support frame 17 can support the bottom of the housing 1. Since the housing 1 is composed of multiple plates fixedly combined by bolts and can be disassembled, the sealing ring 18 can prevent the liquid from leaking out from the gap of the housing 1. The liquid in the housing 1 circulates through the communication grooves 19 on both sides.

[0031] Working principle: When using a new impeller of a hydraulic pump, first install the liquid delivery hose on the surface of the connecting pipe 6, clamp and fix both sides of the liquid delivery hose through the two groups of clamping plates 8, and then rotate the handwheel 11 to fix the positions of the two groups of clamping plates 8. When pumping the liquid, place the liquid delivery hose on one side of the housing 1 into the liquid, and then through the rotation of the blades 4, pump the liquid into the liquid delivery hose, and then transport it into the housing 1 through the liquid delivery hose and transport the liquid into the liquid delivery hose on the other side through the communication grooves 19 on both sides of the housing 1, thereby completing the transportation of the liquid.
