Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to an agricultural water diversion device. Background Technology

[0002] In agricultural irrigation, diversion equipment is a core component of fluid transport systems, and its performance directly affects the efficiency of water resource utilization. Traditional diversion devices mostly use power equipment such as centrifugal pumps or plunger pumps to achieve water flow through fixed power output. However, such devices have significant technical defects: First, the flow regulation of existing equipment relies on valve opening control, which leads to increased system energy consumption and throttling losses, failing to meet the technical requirements of energy-saving irrigation; second, the mechanical structure limits dynamic adjustment capabilities, making it impossible to accurately regulate water volume based on real-time parameters such as crop growth cycle and soil moisture; third, traditional one-way valve structures are prone to leakage under high-pressure conditions, affecting the system's sealing performance.

[0003] A search of existing publicly available water diversion devices reveals that they mainly rely on motor-driven impeller rotation to achieve water pumping, which presents the following technical problems: 1) The fixed impeller speed results in an unadjustable flow rate; 2) Using ball valves to regulate the flow rate causes significant pressure loss; 3) There is a lack of dynamic compensation design for the sealing structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an agricultural water diversion device.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: an agricultural water diversion device is provided, including a shell body, a water inlet pipe is provided on one side of the shell body, a water outlet is provided on one side of the top of the water inlet pipe, a water inlet is provided at the bottom of the water inlet pipe, the water outlet and the water inlet respectively penetrate the shell body, a pumping mechanism is provided on one side of the water inlet pipe, the movable end of the pumping mechanism is slidably connected to the inner wall of the water inlet pipe, and a power output mechanism is provided at the top of the pumping mechanism, the output end of the power output mechanism is rotatably connected to the pumping mechanism.

[0006] Through the above technical solution, by coordinating the power output mechanism and the pumping mechanism, water pumping irrigation can be achieved while controlling the water output, thus realizing scientific irrigation and meeting the water needs of different crops at different stages, thereby improving the efficiency of water resource utilization.

[0007] Furthermore, the pumping mechanism includes a sealing plug, a first closing leaf door is provided at the center of the sealing plug, the side wall of the first closing leaf door is rotatably connected to the sealing plug, a second closing leaf door is provided at the bottom end of the first closing leaf door, and the side wall of the second closing leaf door is rotatably connected to the water inlet pipe.

[0008] Through the above technical solution, one end of the inlet can contact the water body through a flexible hose. When the sealing plug moves upward, the space below the sealing plug increases, the air volume expands, and the air pressure decreases. Under the action of external atmospheric pressure, water is forced into the water pipe and pushes open the second closed leaf door at the bottom of the water pipe, entering the space below the sealing plug. When the sealing plug moves downward, under the action of water pressure, the first closed leaf door opens, and water in the space below the sealing plug enters the space above the sealing plug. At the same time, due to the downward pressure of the sealing plug on the water below, the water pressure in the water pipe increases, and the second closed leaf door at the bottom of the water pipe closes, thereby preventing water backflow. When the sealing plug repeatedly moves up and down, water is continuously drawn up and flows out through the outlet, thereby achieving the purpose of irrigation.

[0009] Furthermore, the outer wall of the sealing plug corresponds to the inner wall of the water inlet pipe, and the sealing plug is slidably connected to the water inlet pipe.

[0010] Through the above technical solution, by tightly fitting the outer edge of the sealing plug to the inner wall of the water pipe, a relatively sealed space is formed between the sealing plug and the inner wall of the water pipe when the sealing plug moves up and down.

[0011] Furthermore, a first connecting rod is rotatably connected to the top of the sealing plug, a second connecting rod is rotatably connected to the top of the first connecting rod, a support frame is provided at the end of the second connecting rod away from the first connecting rod, the support frame is rotatably connected to the second connecting rod, and the support frame is fixedly connected to the side wall of the outer shell body.

[0012] Through the above technical solution, by the rotational connection between the second link and the first link, and the rotational connection between the first link and the sealing plug, the second link can drive the sealing plug at the bottom of the first link to move up and down along the inner wall of the water pipe when it swings up and down.

[0013] Furthermore, a third link is provided between the support frame and the second link. The two ends of the third link are rotatably connected to the support frame and the second link, respectively. The top end of the third link is connected to the top end of the second link by a hanging spring. A limit screw is provided at the bottom end of the third link, and the limit screw is threadedly connected to the support frame.

[0014] With the above technical solution, when the limiting screw is not in contact with the third link, the second and third links can be regarded as a single moving unit, and the center of their up-and-down swing is the hinge point between the third link and the support frame. At this time, the limiting screw can be rotated through the operating hole opened on the side wall of the outer shell. When the limiting screw moves upward and contacts the bottom end of the third link, the swing center of the second and third links changes to the hinge point between the second and third links. At this time, the stroke of the sealing plug along the inner wall of the water inlet pipe becomes longer. When the compression depth of the sealing plug increases, the degree of gas compression in the water inlet pipe will increase, and the gas pressure difference will also be greater. The larger pressure difference will provide greater power and will force more water into the water inlet pipe, thereby increasing the water output. The work stroke of the sealing plug can be controlled by rotating the limiting screw, thereby realizing the change in water output.

[0015] Furthermore, the power output mechanism includes a drive rod, one end of which is rotatably connected to the second connecting rod, and the other end of which is rotatably connected to a U-shaped rod, the two ends of which are rotatably connected to the two side walls at the top of the support frame, respectively.

[0016] Furthermore, one end of the U-shaped rod passes through the support frame and is fixedly connected to a first transmission wheel. A motor is provided on one side of the first transmission wheel, and a second transmission wheel is fixedly connected to the output end of the motor. The second transmission wheel and the first transmission wheel are connected by a transmission belt.

[0017] Through the above technical solution, the motor output drives the second transmission wheel to rotate, the second transmission wheel drives the first transmission wheel to rotate through the transmission belt, the first transmission wheel rotates and drives the U-shaped rod to rotate, and when the U-shaped rod rotates, it drives the drive rod and the second connecting rod to swing up and down.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention, through the coordinated operation of a power output mechanism and a pumping mechanism, achieves irrigation while simultaneously controlling the water output, enabling scientific irrigation and meeting the water needs of different crops at different stages, thereby improving water resource utilization efficiency. The reciprocating lifting and lowering motion of the sealing plug changes the air pressure inside the water inlet pipe. Then, under the influence of atmospheric pressure, water is discharged through the water inlet pipe, achieving the purpose of water intake. The switching of the swing centers of the second and third connecting rods alters the working stroke of the sealing plug, controlling the change in air pressure inside the water inlet pipe. This change in the pressure difference between the inside and outside controls the water output. By flexibly adjusting the water output, stable irrigation is ensured, crop growth is guaranteed, and agricultural production efficiency is improved. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figure 1 - Figure 6 As shown, an agricultural water diversion device includes an outer shell 1, a water inlet pipe 4 is provided on one side of the outer shell 1, an outlet 2 is provided on one side of the top of the water inlet pipe 4, an inlet 3 is provided at the bottom of the water inlet pipe 4, the outlet 2 and the inlet 3 respectively penetrate the outer shell 1, a pumping mechanism 5 is provided on one side of the water inlet pipe 4, the movable end of the pumping mechanism 5 is slidably connected to the inner wall of the water inlet pipe 4, and a power output mechanism 6 is provided at the top of the pumping mechanism 5, the output end of the power output mechanism 6 is rotatably connected to the pumping mechanism 5.

[0029] The pumping mechanism 5 includes a sealing plug 503, a first closing leaf gate 504 is provided at the center of the sealing plug 503, the side wall of the first closing leaf gate 504 is rotatably connected to the sealing plug 503, and a second closing leaf gate 505 is provided at the bottom end of the first closing leaf gate 504, the side wall of the second closing leaf gate 505 is rotatably connected to the water inlet pipe 4.

[0030] Both the first closed leaf valve 504 and the second closed leaf valve 505 are upward-opening one-way valves. One end of the inlet 3 can contact the water body through a connecting hose. When the sealing plug 503 moves upward, the space below the sealing plug 503 increases, the air volume expands, and the air pressure decreases. Under the action of the external atmospheric pressure, water is forced into the water pipe 4 and pushes open the second closed leaf valve 505 at the bottom of the water pipe 4, entering the space below the sealing plug 503. When the sealing plug 503 moves downward, under the action of water pressure, the first closed leaf valve 504 opens, and the water in the space below the sealing plug 503 enters the space above the sealing plug 503. At the same time, due to the downward compression of the water below by the sealing plug 503, the water pressure in the water pipe 4 increases, and the second closed leaf valve 505 at the bottom of the water pipe 4 closes, thereby preventing water backflow. When the sealing plug 503 repeatedly moves up and down, water is continuously drawn up and flows out through the outlet 2, thereby achieving the purpose of irrigation.

[0031] The outer wall of the sealing plug 503 corresponds to the inner wall of the water inlet pipe 4. The sealing plug 503 is slidably connected to the water inlet pipe 4. Through the tight fit between the outer edge of the sealing plug 503 and the inner wall of the water inlet pipe 4, a relatively sealed space is formed between the sealing plug 503 and the inner wall of the water inlet pipe 4 when the sealing plug 503 moves up and down.

[0032] The top of the sealing plug 503 is rotatably connected to a first connecting rod 501, and the top of the first connecting rod 501 is rotatably connected to a second connecting rod 502. A support frame 509 is provided at the end of the second connecting rod 502 away from the first connecting rod 501. The support frame 509 is rotatably connected to the second connecting rod 502 and is fixedly connected to the side wall of the outer shell body 1.

[0033] Through the rotational connection between the second link 502 and the first link 501, and the rotational connection between the first link 501 and the sealing plug 503, when the second link 502 swings up and down, it can drive the sealing plug 503 at the bottom of the first link 501 to move up and down along the inner wall of the water pipe 4.

[0034] A third link 506 is provided between the support frame 509 and the second link 502. The two ends of the third link 506 are rotatably connected to the support frame 509 and the second link 502 respectively. The top end of the third link 506 is connected to the top end of the second link 502 through a hanging spring 507. A limit screw 508 is provided at the bottom end of the third link 506, and the limit screw 508 is threadedly connected to the support frame 509.

[0035] When the limiting screw 508 is not in contact with the third link 506, the second link 502 and the third link 506 can be regarded as a single moving unit. The center of their up-and-down swing is the hinge point between the third link 506 and the support frame 509. At this time, the limiting screw 508 can be rotated through the operating hole opened on the side wall of the outer shell 1. When the limiting screw 508 moves upward and contacts the bottom end of the third link 506, the swing center of the second link 502 and the third link 506 changes to the hinge point between the second link 502 and the third link 506. At this time, the stroke of the sealing plug 503 along the inner wall of the water inlet pipe 4 becomes longer. When the compression depth of the sealing plug 503 increases, the degree of gas compression in the water inlet pipe 4 will increase, and the gas pressure difference will also be greater. The larger pressure difference will provide greater power and will force more water into the water inlet pipe 4, thereby increasing the water output. The working stroke of the sealing plug 503 can be controlled by rotating the limiting screw 508, thereby realizing the change in water output.

[0036] The power output mechanism 6 includes a drive rod 601. One end of the drive rod 601 is rotatably connected to the second connecting rod 502, and the other end of the drive rod 601 is rotatably connected to a U-shaped rod 602. Both ends of the U-shaped rod 602 are rotatably connected to the two side walls at the top of the support frame 509, respectively.

[0037] One end of the U-shaped rod 602 passes through the support frame 509 and is fixedly connected to the first transmission wheel 603. A motor 606 is provided on one side of the first transmission wheel 603. The output end of the motor 606 is fixedly connected to the second transmission wheel 604. The second transmission wheel 604 and the first transmission wheel 603 are connected by a transmission belt 605.

[0038] The output end of motor 606 drives the second transmission wheel 604 to rotate. The second transmission wheel 604 drives the first transmission wheel 603 to rotate through the transmission belt 605. The rotation of the first transmission wheel 603 drives the U-shaped rod 602 to rotate. When the U-shaped rod 602 rotates, it drives the drive rod 601 and the second connecting rod 502 to swing up and down.

[0039] When using this utility model, the motor 606 is first started. The output end of the motor 606 drives the second transmission wheel 604 to rotate. The second transmission wheel 604 drives the first transmission wheel 603 to rotate through the transmission belt 605. The rotation of the first transmission wheel 603 drives the U-shaped rod 602 to rotate. When the U-shaped rod 602 rotates, it drives the drive rod 601 and the second connecting rod 502 to swing up and down. The second connecting rod 502 drives the sealing plug 503 to move up and down along the inner wall of the water pipe 4 through the first connecting rod 501. The reciprocating up and down movement of the sealing plug 503 realizes the change of air pressure in the water pipe 4. Then, under the action of atmospheric pressure, the water is discharged through the outlet 2, thereby achieving the purpose of water intake.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
