Description

Technical Field

[0001] This invention relates to the field of arid microenvironment regulation equipment technology, specifically to a water replenishment device for water retention regulation in arid parks. Background Technology

[0002] In arid regions, microenvironmental regulation equipment is used for plant conservation. By finely regulating plants within a small microenvironment, normal plant ecological growth can be achieved in an overall arid environment. Taking total microenvironmental water retention regulation as an example, existing methods typically use drip irrigation or smart irrigation equipment for microenvironmental water replenishment regulation. However, drip irrigation equipment has limited installation conditions, and its water supply mode results in an unadjustable continuous water supply, making it unsuitable for complex and changeable external environments. It is prone to damage to the microenvironment due to insufficient water supply during windy and sandy weather. Smart irrigation equipment, on the other hand, is not suitable for large-scale installation or outdoor environments due to its high cost and high maintenance requirements. Therefore, research and development of new equipment is needed to provide an inexpensive water replenishment regulation device that can adjust water supply according to environmental changes.

[0025] When using this device, fill the water tank 2 with water, connect the irrigation equipment to the outlet pipe of the water pump cylinder 3 through a pipe, and set up the device on the side of the microenvironment that needs irrigation. In a windy environment, the wind-driven cup rotor 7 drives the drive shaft 6 to rotate. The drive shaft 6 drives the flywheel 10-1 to rotate through the gear reducer 9-3. When the flywheel 10-1 rotates and drives the boss 10-2 on it to abut against the support seat 22, the boss 10-2 pushes the support seat 22, thereby driving the transmission guide seat 21 to move downward on the transmission guide rod 20 through the support seat 22. The transmission guide seat 21 drives the transmission shaft 23 to rotate through the meshing main rack 25 and main gear 24. The transmission shaft 23... The meshing secondary gear 26 and secondary rack 27 drive the lifting guide seat 9-2 to move downward. When the lifting guide seat 9-2 contacts the transmission pin 19, it pushes the guide frame 16 downward through the transmission pin 19. This, in turn, drives the lifting drive seat 8-2 to slide downward on the lifting slide rail 8-1. Consequently, the lifting drive seat 8-2 presses down on the drive arm 15, which in turn drives the connecting arm 13 to rise. The connecting arm 13, through the connecting rod 14, pulls the one-way valve piston 4 upward, thereby raising the water level in the water pump cylinder 3 and allowing the water in the water pump cylinder 3 to be discharged for irrigation. After the boss 10-2 passes its lowest point and rises, the boss 10-2 disengages from the support seat 22. When pushed downwards, the lifting drive seat 8-2, which has been lowered to its lowest point, is pushed upwards by the support spring 8-5. This causes the lifting drive seat 8-2 and the transmission guide seat 21 to rise. The rise of the lifting drive seat 8-2 then lifts the drive arm 15, causing the one-way valve piston 4 to descend. This moves the water pressure from below the one-way valve piston 4 to above it, preparing for the next pumping cycle. Rotating the threaded rod 17 adjusts the position of the adjusting seat 18 within the guide frame 16, thereby adjusting the height of the transmission pin 19. This adjusts the position of the lifting guide seat 9-2 in contact with the transmission pin 19 during its stroke, thus controlling the stroke of the lifting guide seat 9-2 pushing the transmission pin 19, and ultimately controlling the lifting drive seat 8-2. The single movement stroke, that is, the single working stroke of the one-way valve piston 4, is adjusted to regulate the single pumping volume. Adjusting the transmission pin 19 to move downward on the guide frame 16 shortens the single reciprocating stroke of the one-way valve piston 4, that is, reduces the pumping volume. Conversely, the transmission pin 19 rising increases the single pumping volume. Installing a boss 10-2 on the flywheel 10-1 means that one rotation of the flywheel 10-1 drives the transmission guide seat 21 to perform one reciprocating motion through the boss 10-2. Installing several bosses 10-2 on the flywheel 10-1 means that one rotation of the flywheel 10-1 drives the transmission guide seat 21 to perform several reciprocating motions through the several bosses 10-2, thereby adjusting the frequency of water pumping through the one-way valve piston 4.When the wind speed driving the cup rotor 7 is different, the rotation speed of the drive shaft 6 is different. The drive shaft 6 drives the mounting bracket 11-1 to rotate, which in turn drives the speed limiting guide rod 11-3 and the permanent magnet 11-5 on the mounting bracket 11-1 to rotate and generate centrifugal force. When the centrifugal force is greater than the pre-tension force of the return spring 11-4, the permanent magnet 11-5 moves towards the conductive brake ring 11-6. When the permanent magnet 11-5 approaches the conductive brake ring 11-6, it cooperates with it to generate electromagnetic eddy currents, thereby causing the mounting bracket 11-1 to rotate. 1-1. The kinetic energy of the rotating permanent magnet 11-5 is converted into heat energy by the conductive brake ring 11-6, thereby limiting the rotation speed of the mounting bracket 11-1. This stabilizes the maximum rotational speed of the mounting bracket 11-1 and the drive shaft 6 within a small fluctuation range, creating a braking balance between the permanent magnet 11-5 and the conductive brake ring 11-6. When the rotation speed of the drive shaft 6 and the mounting bracket 11-1 is below the maximum speed, the permanent magnet 11-5 will not pop out and will not generate speed-limiting damping with the conductive brake ring 11-6.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. This device, through the cooperation of connecting arm 13, drive arm 15 and connecting rod 14, realizes the reciprocating movement of one-way valve piston 4 by swinging drive arm 15, thereby realizing water pumping and irrigation. 2. This device uses a flywheel 10-1 with a boss 10-2 to drive the transmission guide seat 21 to move up and down. The transmission shaft 23 enables the transmission between the transmission guide seat 21 and the lifting guide seat 9-2. The drive shaft 6 with a wind cup rotor 7 drives the flywheel 10-1 to rotate, thereby pressing the lifting guide seat 9-2. Then, through the cooperation between the lifting guide seat 9-2 and the transmission pin 19 on the lifting drive seat 8-2, the lifting drive seat 8-2 is moved. 3. This device has an adjustable adjustment seat 18 on the lifting drive seat 8-2 through the guide frame 16, thereby adjusting the height of the transmission pin 19. Through the cooperation between the lifting guide seat 9-2 and the transmission pin 19, the single downward stroke of the lifting drive seat 8-2 can be adjusted, thereby adjusting the single pumping volume. 4. In response to different wind conditions, this device incorporates a centrifugally triggered permanent magnet 11-5 on the drive shaft 6 via a speed-limiting guide rod 11-3 and a return spring 11-4. Through the cooperation of the permanent magnet 11-5 and the conductive brake ring 11-6, the conversion of kinetic energy and thermal energy is achieved, thereby limiting the maximum speed of the drive shaft 6.
