Description

Technical Field

[0001] This invention relates to the field of crop irrigation technology, and more particularly to a crop irrigation system. Background Technology

[0002] In agricultural production, water resources are fundamental to the healthy growth of crops, and efficient and stable irrigation systems are core elements for achieving rational water resource utilization, ensuring healthy crop growth, and improving crop yield and quality. With the continuous growth of the global population and the ever-increasing demand for agricultural products, agricultural production faces enormous pressure, placing more stringent demands on the efficiency and stability of irrigation systems. Irrigation pipes, as the "blood vessels" of the irrigation system, bear the crucial responsibility of accurately delivering water to every corner of the farmland. Their connection structures, like the nodes of these "blood vessels," directly determine whether the entire irrigation system can operate smoothly. Defects in the connection structure, like blockages or leaks in blood vessels, will severely affect the performance of the irrigation system, thus posing a challenge to the sustainable development of agricultural production. Therefore, the design of a crop irrigation system is essential.

[0003] Existing crop irrigation pipelines mostly use simple socket or threaded connections to ensure connection stability. These connections are difficult to withstand water flow impact, soil settlement, and thermal expansion and contraction of the pipeline. As a result, the connections are prone to loosening, increasing the risk of leakage. Furthermore, it is difficult to detect and deal with potential problems such as leakage and loosening in a timely manner. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figures 1 to 10 Example 1:

[0036] This invention proposes a crop irrigation system, comprising: a mounting frame 4; a control box 43 mounted on the mounting frame 4; two water pumps 41 mounted on the mounting frame 4; suction pipes 411 connected to the inlet ends of the two water pumps 41; a main pipe 42 connected to the outlet ends of the two water pumps 41; a first connecting pipe head 1 connected to the main pipe 42; two through slots formed on the first connecting pipe head 1; locking plates 11 hinged in each of the two through slots; reinforcing holes 111 provided on each of the two locking plates 11; a second connecting pipe head 2 mounted on the first connecting pipe head 1; locking grooves 22 corresponding to the locking plates 11 provided on the outer circumference of the second connecting pipe head 2; and protruding structures provided on each of the two locking plates 11, which are fitted and pressed against the locking grooves 22. Inside, the upper and lower ends of the second connecting pipe head 2 are both fixed with reinforcing rods 21, and the upper and lower ends of the first connecting pipe head 1 are both fixed with fixing seats 12. The fixing seats 12 are provided with through holes, and the reinforcing rods 21 are located in the through holes of the fixing seats 12. The fixing seats 12 are threaded with adjusting screws 122, and two sets of push rods 123 are movable on the fixing seats 12. The front and rear ends of the fixing seats 12 are both bolted with side seats 124. The side seats 124 are provided with through holes, and a movable connecting cylinder 125 is installed in the through holes. The upper and lower ends of the connecting cylinder 125 are both set as inclined surfaces. Two sets of clamping rods 121 are movable on the fixing seats 12. The end of the clamping rod 121 away from the adjusting screw 122 is set as an inclined surface, and this inclined surface is adapted to the inclined surface of the lower end of the connecting cylinder 125.

[0037] In this invention, the adjusting screw 122 has a tapered surface on its side, the front and rear ends of the push rod 123 are both inclined surfaces, and the push rod 123 has a waist-shaped groove. A first insert rod 1231 is fixedly installed on the fixed seat 12. The first insert rod 1231 is located in the waist-shaped groove on the push rod 123, and a first spring 1232 is installed in the waist-shaped groove on the push rod 123. The two ends of the first spring 1232 abut against the first insert rod 1231 and the groove wall of the waist-shaped groove on the push rod 123, respectively. A waist-shaped through groove is opened on the connecting cylinder 125, and a second insert rod 1241 is fixedly installed on the side seat 124. The second insert rod 1241 is located in the waist-shaped through groove on the connecting cylinder 125, and a second spring 1251 is installed in the waist-shaped through groove on the connecting cylinder 125. The two ends of the second spring 1251 abut against the second insert rod 1241 and the connecting cylinder 125, respectively. The function of the groove wall of the waist-shaped through groove 25 is as follows: when the adjusting screw 122 is rotated, the conical surface on its side pushes the push rod 123 to move. Since the front and rear ends of the push rod 123 are both inclined surfaces, and the waist-shaped groove cooperates with the first insertion rod 1231, under the buffering effect of the first spring 1232, the push rod 123 can be smoothly pushed forward in a specific direction. As the push rod 123 moves, its front end will contact the connecting cylinder 125 and push the connecting cylinder 125 to move in the through hole of the side seat 124. During the movement, the inclined surfaces of the upper and lower ends of the connecting cylinder 125 are adapted to the inclined surface of the clamping rod 121 away from the adjusting screw 122, thereby pushing the clamping rod 121 to move towards the reinforcing rod 21. Finally, the two sets of clamping rods 121 clamp the reinforcing rod 21, further enhancing the stability of the connection between the first connecting tube head 1 and the second connecting tube head 2.

[0038] In this invention, a sealing gasket is installed inside the first connecting pipe head 1. The sealing gasket is located at the joint between the first connecting pipe head 1 and the second connecting pipe head 2. The sealing gasket is made of rubber material. Its function is that, due to the good flexibility and high elasticity of the rubber material, it can tightly fit the tiny gap between the first connecting pipe head 1 and the second connecting pipe head 2 when they are assembled. When the irrigation system is running, the internal water flow will generate a certain pressure. The rubber sealing gasket can effectively resist the water pressure with its elasticity and prevent water from seeping out from the joint.

[0039] In this invention, a threaded pipe 23 is fixedly connected to the left side of the second connecting pipe head 2. The threaded pipe 23 is made of polyurethane elastomer material. An extension pipe 24 is fixedly connected to the left end of the threaded pipe 23. A branch pipe 5 is connected to the extension pipe 24. The branch pipe 5 is set in the field and has spray holes. Its function is that the excellent elasticity of polyurethane elastomer can effectively buffer the impact force generated by the irrigation water flow in the pipe, reduce the impact damage of the water flow to the pipe connection, ensure the stability of the connection structure, and reduce the risk of leakage. The extension pipe 24 fixedly connected to the left end of the threaded pipe 23 further expands the irrigation range. In the farmland irrigation scenario, the extension pipe 24 can be extended to a specific area. The spray holes on the branch pipe 5 can disperse the water flow into small water droplets or water flow, evenly covering the farmland area and achieving precision irrigation.

[0040] In Example 2, based on Example 1, a first clamping plate 3 and a second clamping plate 31 are installed on the extension tube 24. Both the first clamping plate 3 and the second clamping plate 31 are X-shaped structures and are connected by bolts. The extension tube 24 is clamped between the first clamping plate 3 and the second clamping plate 31. The front end of the first clamping plate 3 has a threaded hole. A support 32 is bolted onto the first clamping plate 3. The support 32 has an L-shaped structure. A base 33 is bolted to the upper end of the support 32. An arc-shaped through groove is provided on the base 33. A power supply base 34 is bolted into the arc-shaped through groove on the base 33. A motor control system is installed inside the power supply base 34. The motor control system includes a wireless controller. A first motor 35 is installed at the upper end of the power supply base 34. The output shaft of the first motor 35 is fixedly connected to the upper end of the power supply base 34. A bracket 351 is bolted onto the first motor 35. A second motor is bolted onto the bracket 351. 352, A clamping seat 353 is bolted to the output shaft of motor 352. Motor 36 is bolted to clamping seat 353. A connecting frame 361 is fixedly mounted on the output shaft of motor 36. A frame 362 is bolted to connecting frame 361. A visual inspection alarm 37 is bolted to frame 362. Its function is as follows: The output shaft of motor 35 is fixedly connected to the upper end of power supply base 34, which can drive the entire assembly mounted on power supply base 34 to rotate, expanding the monitoring range of visual inspection alarm 37. Bracket 351 connects motor 35 and motor 352. Motor 352 drives motor 36 to rotate in a specific direction through clamping seat 353, further finely adjusting the angle of visual inspection alarm 37. Motor 36 mounts visual inspection alarm 37 through connecting frame 361 and frame 362, which can realize multi-angle adjustment of visual inspection alarm 37.

[0041] In Example 3, based on Examples 1 and 2, the wireless controller is electrically connected to motor 35 (number 1), motor 352 (number 2), and motor 36 (number 3). Each of these motors is equipped with an electromagnetic brake, which is also electrically connected to the wireless controller. The function of this electromagnetic brake is to allow maintenance personnel to remotely send commands via the wireless controller without being physically present. Based on the layout of the irrigation pipeline and the monitoring focus of different areas, the rotation angle of motor 35 can be flexibly adjusted, driving the power supply base 34 and the equipment above it to rotate, thus enabling the visual inspection alarm 37 to cover a wider area. The system controls the second motor 352 and uses the clamping seat 353 to precisely adjust the angles of the third motor 36 and the visual inspection alarm 37, ensuring comprehensive and thorough monitoring of the pipe connection points and surrounding areas. This remote control greatly improves the efficiency of monitoring work and reduces manpower and time costs. When the motor drives the visual inspection alarm 37 to rotate to the specified angle, the wireless controller can immediately trigger the electromagnetic brake. The electromagnetic brake quickly brakes the output shaft of the motor to prevent it from rotating unexpectedly due to external vibration, wind interference or other unforeseen factors, ensuring that the angle of the visual inspection alarm 37 is firmly locked.

[0042] The working principle of this invention: After the two water pumps 41 on the mounting bracket 4 are started, they draw water from the water source through the suction pipe 411, pressurize it, and then transport it to the first connecting pipe head 1 through the main pipe 42. The first connecting pipe head 1 and the second connecting pipe head 2 are initially positioned by the locking plate 11 and the locking groove 22. The protruding structure of the locking plate 11 is embedded in the locking groove 22 to form a mechanical limit. Then, the adjusting screw 122 is rotated, and its side conical surface pushes the push rod 123 to move to both sides. The inclined surface of the front end of the push rod 123 squeezes the connecting cylinder 125 so that it moves laterally in the through hole of the side seat 124. The inclined surfaces of the upper and lower ends of the connecting cylinder 125 push the clamping rod 121 to clamp the reinforcing rod 21 (the reinforcing rod 21 is inserted into the through hole of the fixing seat 12). With the buffering of the first spring 1232 and the second spring 1251, a rigid connection is achieved. The rubber sealing gasket in the first connecting pipe head 1 deforms elastically under water pressure, filling the gap to ensure a seal and prevent water leakage. The water flows through the left side of the second connecting pipe head 2. The threaded pipe 23 (made of polyurethane elastomer) enters the extension pipe 24. The elasticity of the threaded pipe 23 buffers the impact of water flow, reducing pipe vibration and loss at the connection. The extension pipe 24 distributes water to the field through the branch pipe 5. Its extended design can cover remote irrigation areas. The extension pipe 24 is fixed to the support 32 through the first clamp 3 and the second clamp 31 (connected by X-type structural bolts). The base 33 on the support 32 is equipped with the power supply seat 34 through the arc-shaped through groove. The wireless controller sends a command to control the first motor 35 to drive the power supply seat 34 to rotate. The second motor 352 adjusts the angle of the third motor 36 through the clamping seat 353. The third motor 36 drives the visual detection alarm 37 to perform multi-directional monitoring through the connecting frame 361 and the frame 362. When the specified angle is reached, the wireless controller triggers the electromagnetic brake to lock the motor output shaft to prevent external interference from causing angle deviation, realizing real-time monitoring and abnormal early warning of pipe connection and field irrigation conditions.
