Description

Technical Field

[0001] The present invention relates to the technical field of crop irrigation, and in particular to a crop irrigation system. Background Art

[0002] In the field of agricultural production, water resources are the fundamental guarantee for the healthy growth of crops, and an efficient and stable irrigation system is the core element for achieving the rational use of water resources, ensuring the healthy growth of crops, and improving the yield and quality of crops. With the continuous growth of the global population and the increasing demand for agricultural products, agricultural production is facing tremendous pressure, and more stringent requirements are placed on the efficiency and stability of the irrigation system. Irrigation pipes, as the "blood vessels" of the irrigation system, bear the important task of accurately transporting water to every corner of the farmland. Their connection structure is like the nodes of the "blood vessels", which directly determines whether the entire irrigation system can operate smoothly. If there are defects in the connection structure, it will be like a blockage or leakage in the blood vessels, seriously affecting the performance of the irrigation system, and thus posing a challenge to the sustainable development of agricultural production. Therefore, a crop irrigation system is designed.

[0003] In terms of connection stability, existing crop irrigation pipes mostly use simple socket or threaded connections, which are difficult to withstand the impact of water flow, external forces of soil settlement and thermal expansion and contraction of pipes, causing the connections to loosen easily, increasing the risk of leakage, and making it difficult to promptly detect and deal with potential faults such as leakage and loosening.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

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

[0036] The present invention proposes a crop irrigation system, comprising: a mounting frame 4; a control box 43 is mounted on the mounting frame 4; two water pumps 41 are mounted on the mounting frame 4; the water inlet ends of the two water pumps 41 are connected to a water suction pipe 411; the water outlet ends of the two water pumps 41 are connected to a main pipe 42; the main pipe 42 is connected to a first connecting pipe head 1; the first connecting pipe head 1 is provided with two through grooves; locking plates 11 are hinged in the two through grooves; the two locking plates 11 are provided with reinforcement holes 111; the first connecting pipe head 1 is provided with a second connecting pipe head 2; the outer circumference of the second connecting pipe head 2 is provided with a locking groove 22 corresponding to the locking plate 11; the two locking plates 11 are provided with a protruding structure; the protruding structures on the two locking plates 11 are adaptively pressed on the locking groove 22 Inside, the upper and lower ends of the second connecting pipe head 2 are fixed with reinforcement rods 21, and the upper and lower ends of the first connecting pipe head 1 are fixed with a fixing seat 12, a through hole is provided on the fixing seat 12, the reinforcement rod 21 is located in the through hole on the fixing seat 12, an adjusting screw 122 is threaded on the fixing seat 12, and two groups of push rods 123 are movable on the fixing seat 12, the front and rear ends of the fixing seat 12 are both installed with side seats 124 by bolts, the side seats 124 are provided with a through hole, and a movable connecting tube 125 is installed in the through hole, the upper and lower ends of the connecting tube 125 are set to inclined surfaces, and two groups of clamping rods 121 are movable on the fixing seat 12, and the end of the clamping rod 121 away from the adjusting screw 122 is set to an inclined surface, and the inclined surface is adapted to the inclined surface of the lower end of the connecting tube 125.

[0037] The first and second springs 1232 are installed in the waist-shaped groove on the push rod 123, and the two ends of the No. 1 spring 1232 respectively abut against the No. 1 plug rod 1231 and the groove wall of the waist-shaped groove on the push rod 123. A waist-shaped through groove is provided on the connecting tube 125, and a No. 2 plug rod 1241 is fixedly installed on the side seat 124. The No. 2 plug rod 1241 is located in the waist-shaped through groove on the connecting tube 125, and a No. 2 spring 1251 is installed in the waist-shaped through groove on the connecting tube 125. The two ends of the No. 2 spring 1251 respectively abut against the No. 2 plug rod 1241 and the connecting tube 1 The function of the groove wall of the waist-shaped groove on 25 is: when the adjusting screw 122 is rotated, the conical surface of its side pushes the pushing rod 123 to move. Since the front and rear ends of the pushing rod 123 are both inclined surfaces, and the waist-shaped groove cooperates with the No. 1 plug rod 1231, under the buffering action of the No. 1 spring 1232, the pushing rod 123 can be smoothly pushed in a specific direction. As the pushing rod 123 moves, its front end will contact the connecting tube 125 and push the connecting tube 125 to move in the through hole of the side seat 124. The inclined surfaces of the upper and lower ends of the connecting tube 125 are adapted to the inclined surfaces of the clamping rod 121 away from the adjusting screw 122 during the movement, thereby pushing the clamping rod 121 to move in the direction of the reinforcement rod 21. Finally, the two sets of clamping rods 121 achieve the clamping of the reinforcement rod 21, further enhancing the stability of the connection between the first connecting pipe head 1 and the second connecting pipe head 2.

[0038] In the present 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: since the rubber material has good flexibility and high elasticity, when the first connecting pipe head 1 and the second connecting pipe head 2 are assembled, it can fit tightly into the tiny gap between the two. 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 by virtue of its elasticity, preventing water from seeping out from the connection gap.

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

[0040] Embodiment 2. On the basis of embodiment 1, a No. 1 plywood 3 and a No. 2 plywood 31 are installed on the extension tube 24. Both the No. 1 plywood 3 and the No. 2 plywood 31 are set to an X-shaped structure, and the No. 1 plywood 3 and the No. 2 plywood 31 are connected by bolts. The extension tube 24 is clamped between the No. 1 plywood 3 and the No. 2 plywood 31. A threaded hole is provided at the front end of the No. 1 plywood 3. A support 32 is installed on the No. 1 plywood 3 by bolts. The support 32 is an L-shaped structure. The upper end of the support 32 is installed with a base 33 by bolts. An arc-shaped through groove is provided on the base 33. A power supply seat 34 is installed in the arc-shaped through groove on the base 33 by bolts. A motor control system is provided inside the power supply seat 34. The motor control system includes a wireless controller. A No. 1 motor 35 is provided at the upper end of the power supply seat 34. The output shaft of the No. 1 motor 35 is fixedly connected to the upper end of the power supply seat 34. A bracket 351 is installed on the No. 1 motor 35 by bolts, and a No. 2 motor is installed on the bracket 351 by bolts. 352, a clamping seat 353 is installed on the output shaft of the No. 2 motor 352 by bolts, and the No. 3 motor 36 is installed on the clamping seat 353 by bolts, and a connecting frame 361 is fixedly installed on the output shaft of the No. 3 motor 36, and a frame 362 is installed on the connecting frame 361 by bolts, and a visual detection alarm 37 is installed on the frame 362 by bolts. Its function is: the output shaft of the No. 1 motor 35 is fixedly connected to the upper end of the power supply seat 34, which can drive the entire component installed on the power supply seat 34 to rotate, thereby expanding the monitoring range of the visual detection alarm 37, and the bracket 351 connects the No. 1 motor 35 and the No. 2 motor 352, and the No. 2 motor 352 drives the No. 3 motor 36 to rotate in a specific direction through the clamping seat 353, thereby further fine-tuning the angle of the visual detection alarm 37, and the No. 3 motor 36 is installed with the visual detection alarm 37 through the connecting frame 361 and the frame 362, thereby realizing multi-angle adjustment of the visual detection alarm 37.

[0041] Example 3: Based on Example 1 and Example 2, the wireless controller is electrically connected to the No. 1 motor 35, the No. 2 motor 352 and the No. 3 motor 36. The No. 1 motor 35, the No. 2 motor 352 and the No. 3 motor 36 are all equipped with electromagnetic brakes, and the electromagnetic brakes are all electrically connected to the wireless controller. Its function is: maintenance personnel do not need to be on site, they can send instructions through the wireless controller from a distance, and can flexibly adjust the rotation angle of the No. 1 motor 35 according to the layout of the irrigation pipeline and the monitoring focus of different areas, drive the power supply base 34 and the upper equipment to rotate, so that the visual detection alarm 37 can cover a wider range ; Operate the No. 2 motor 352, and use the clamping seat 353 to accurately adjust the angle of the No. 3 motor 36 and the visual detection alarm 37 to ensure comprehensive and no-dead-angle monitoring of the pipeline connection parts and surrounding areas. This remote control greatly improves the efficiency of the monitoring work and reduces manpower input and time costs. When the motor drives the visual detection alarm 37 to rotate to the specified angle, the wireless controller can immediately trigger the electromagnetic brake to work. The electromagnetic brake quickly brakes the output shaft of the motor to prevent it from accidentally rotating due to external vibrations, wind interference or other unexpected factors, ensuring that the angle of the visual detection alarm 37 is firmly locked.

[0042] The working principle of the present invention is as follows: after the two water pumps 41 on the mounting frame 4 are started, water is sucked from the water source through the water suction pipe 411, and is transported to the first connecting pipe head 1 through the main pipe 42 after being pressurized. 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 convex structure of the locking plate 11 is embedded in the locking groove 22 to form a mechanical limit. Subsequently, the adjusting screw 122 is rotated, and the side conical surface thereof pushes the pushing rod 123 to move to both sides. The inclined surface of the front end of the pushing rod 123 squeezes the connecting tube 125 to make it move laterally in the through hole of the side seat 124. The inclined surfaces of the upper and lower ends of the connecting tube 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), and cooperates with the buffering of the No. 1 spring 1232 and the No. 2 spring 1251 to achieve a rigid connection. The rubber sealing gasket in the first connecting pipe head 1 elastically deforms under water pressure, fills the gap to ensure sealing, and prevents water leakage. Water flows through the left side of the second connecting pipe head 2 The threaded tube 23 (made of polyurethane elastomer) enters the extension tube 24. The elasticity of the threaded tube 23 buffers the impact of water flow, reducing pipe vibration and loss at the connection. The extension tube 24 disperses water to the field through the branch pipe 5. Its expanded design can cover remote irrigation areas. The extension tube 24 is fixed to the support 32 through the No. 1 clamp 3 and the No. 2 clamp 31 (X-shaped structural bolt connection). The base 33 on the support 32 is installed with the power supply base 34 through an arc-shaped through groove. The wireless controller sends instructions to control the No. 1 motor 35 to drive the power supply base 34 to rotate. The No. 2 motor 352 adjusts the angle of the No. 3 motor 36 through the clamping base 353. The No. 3 motor 36 drives the visual detection alarm 37 through the connecting frame 361 and the frame 362 for multi-directional monitoring. 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, thereby realizing real-time monitoring and abnormal warning of the pipeline connection and field irrigation conditions.
