Technical Field
[0001] The utility model belongs to the technical field of farmland water conservancy equipment, and particularly relates to an automatic farmland irrigation and drainage system. Background Technique
[0002] Farmland irrigation has always been one of the oldest farming methods of mankind. Historically, it has been regarded as an important technical and skill activity, which is not only applied to food production, but also used for activities such as supplementing soil fertilizers, reducing soil erosion, and protecting rivers and lakes. Today, it is still an important task for many farmers and irrigation engineers, and it is also one of the bases for social and economic stability and human health.
[0003] In the use of agricultural paddy fields, in order to maintain a suitable growth environment for crops, it is necessary to adjust the cultivation environment of the crops, which also includes keeping the water level of the agricultural paddy fields reasonable. Too high or too low water levels are not conducive to crop production, so that the crops can be timely supplemented with an appropriate amount of water. In the prior art, most of them are drained by controlling the drainage outlets between the paddy fields and guided into each farmland through ditches. In this way, it is necessary for manual workers to judge the water level in real time and then dig and fill the ditches. This not only requires manual operation, but also requires frequent detection of the water level in the fields, which is time-consuming and laborious.
[0004] Therefore, we propose an automatic farmland irrigation and drainage system to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 of the embodiments.
[0031] In order to better understand the above technical solutions, the following will specifically describe the above technical solutions in detail with reference to the accompanying drawings of the specification and specific embodiments.
[0032] Referring to Figure 1-2 , an automatic irrigation and drainage system for farmland includes a water storage tank 1. A cam rotor pump 2 is fixedly arranged in the water storage tank 1. The cam rotor pump 2 is a prior art and can change the pumping direction by changing the rotation direction of the motor. An opening is provided on the top surface of the water storage tank 1, which can receive rainwater in rainy weather and play a role in saving resources.
[0033] Referring to Figure 1-3, a mounting plate 3 is fixedly arranged on the water storage tank 1, a spring 4 is fixedly arranged on the mounting plate 3, a connecting pipe 5 is fixedly arranged on the spring 4, a buoy 6 is fixedly arranged on the connecting pipe 5, the inside of the buoy 6 is hollow, a clamping plate 7 is further arranged between the connecting pipe 5 and the spring 4, a plurality of switches 8 for starting the cam rotor pump 2 are fixedly arranged on one side of the water storage tank 1 where the mounting plate 3 is located, the clamping plate 7 abuts against the switches 8, round corners are arranged on the top edge and the bottom edge of the switches 8 to facilitate the clamping plate 7 to press the switches 8 when contacting with the switches 8, the plurality of switches 8 are arranged in sequence from top to bottom, when the buoy 6 moves up and down, the buoy 6 drives the connecting pipe 5 and the clamping plate 7 to move up and down, the clamping plate 7 contacts with the switches 8 to open and close the switches 8, as Figure 3 shown in, each time the clamping plate 7 contacts with the switches 8, the switches 8 are triggered to transmit the signal of the current water level height. When the first switch 8 above is triggered, it indicates that the current water level is relatively high and the cam rotor pump 2 sucks water. Therefore, when the clamping plate 7 rises and contacts with the first switch 8 above, the water level in the water storage tank 1 rises, and the cam rotor pump 2 continuously absorbs the farmland water until the second switch 8 contacts with the clamping plate 7, indicating that the water level in the farmland has dropped and the cam rotor pump 2 stops working. Similarly, the lowermost switch 8 is used to control the cam rotor pump 2 to discharge the water inside the water storage tank 2. The cam rotor pump 2 continuously sucks water, and the position of the clamping plate 7 rises until the second switch 8 contacts with the clamping plate 7, indicating that the water level in the farmland has risen to the normal position and the cam rotor pump 2 stops working.
[0034] This device can be placed at any position in the farmland. Compared with the traditional method of using ditches for drainage, which can only be operated at the edge of the farmland, it increases the scope and breadth of use, and the applicable situations are also more flexible. After the water storage tank 1 is fixed, the height of the buoy 6 will also be indirectly fixed. The height of the prefabricated buoy 6 is such that the lower half of the buoy 6 contacts the water body in the farmland. The buoy 6 is subject to the upward buoyancy force from the water body and the pulling force of the spring 4, and the overall force is in balance.
[0035] When the water level rises, the drainage volume between the buoy 6 and the water body increases, and the upward buoyancy force from the water body increases. To make the overall force tend to balance again, the tensile force of the spring 4 increases. If the water level rises and the volume of the buoy 6 below the water surface increases significantly, the spring 4 will be stretched to affect the switch 8. Although the spring 4 still has a downward tensile force on the buoy 6, the length of the spring 4 will be elongated, and the buoy 6 drives the connecting pipe 5 to move upward. The connecting pipe 5 drives the clamping plate 7 to move upward as well. The clamping plate 7 contacts the switch 8, and the uppermost switch 8 controls the cam rotor pump 2 to absorb water into the water storage tank 1. Similarly, when the water level drops, the drainage volume between the buoy 6 and the water body decreases, and the upward buoyancy force from the water body decreases. To make the overall force tend to balance again, the tensile force of the spring 4 decreases. If the water level drops to affect the lowermost switch 8 and the volume of the buoy 6 below the water surface decreases, the length of the spring 4 will be shortened. Although the spring 4 still has an upward tensile force on the buoy 6, the length of the spring 4 will be shortened, and the buoy 6 drives the connecting pipe 5 to move downward. The connecting pipe 5 drives the clamping plate 7 to move downward as well. The clamping plate 7 contacts the lowermost switch 8, and the lowermost switch 8 controls the cam rotor pump 2 to discharge water into the farmland.
[0036] Referring to Figure 1-3 , by setting the buoy 6 to detect the water level change in the farmland, and then controlling the cam rotor pump 2 to pump and drain the water body in the farmland, thereby changing the water level change in the farmland, keeping the water level in the farmland within a reasonable range. The whole process does not require manual participation, saving the time for detection and operation and improving the production efficiency.
[0037] Referring to Figure 1-3 , the connecting pipe 5 is integrally arranged in a "U" shape. The connecting pipe 5 is a steel pipe. The connecting pipe 5 can connect the clamping plate 7 and the buoy 6. The overall process is that the buoy 6 drives the clamping plate 7 to move up and down, reflecting the change in the water level of the surrounding area on the clamping plate 7, and the clamping plate 7 will contact the switch 8 to change the water volume in the farmland.
[0038] Referring to Figure 1-3 , a protective box 9 is welded on the periphery of the mounting plate 3. A sealed space is formed between the protective box 9 and the water storage tank 1. The connecting pipe 5 is hermetically and slidably arranged on the protective box 9. The protective box 9 can protect the mounting plate 3, the spring 4, the clamping plate 7 and the switch 8 located inside the protective box 9, reducing the degree of erosion they suffer under the action of the water body and increasing the service life of the device.
[0039] Referring to Figure 1-3 , a first limiting ring 10 is fixedly arranged on the inner wall of the protective box 9. The first limiting ring 10 is slidably sleeved outside the connecting pipe 5. By setting the first limiting ring 10, the connecting pipe 5 can maintain its up-and-down movement, reducing the degree of deviation from the vertical direction during its movement and increasing the accuracy of use.
[0040] Reference Figure 4 Figure 4 , the buoy 6 includes a housing 11 fixedly connected to the connecting pipe 5. A balloon 12 is sleeved inside the housing 11. The inside of the housing 11 is hollow and has relatively high strength. The material is suitable for connection use. Under the combined action with the balloon 12, the balloon 12 provides buoyancy for the housing 11.
[0041] Reference Figure 1-3 Figure 1-3 , a second limiting ring 13 is fixedly arranged on the outer wall of the protection box 9. The second limiting ring 13 is slidably sleeved on the outer wall of the housing 11. The second limiting ring 13 can limit the moving position of the buoy 6 and prevent the buoy 6 from shifting.
[0042] Reference Figure 1-3 Figure 1-3 , a plurality of feet 14 are fixedly arranged at the bottom of the water storage tank 1. After determining the position of the water storage tank 1, it is necessary to fix the position of the water storage tank 1 to improve the stability performance of the device and reduce the offset amount of the water storage tank 1. Since the soil quality on the farmland is mostly relatively soft, when directly placing the water storage tank 1, it is necessary to insert its feet 14 deep.
[0043] Reference Figure 1-3 Figure 1-3 , two pipes 15 for draining and sucking water are connected to the cam rotor pump 2. One of them extends below the water surface inside the water storage tank 1, and the other extends outside the water storage tank 1. The pipe 15 extending outside the water storage tank 1 passes through the protection box 9 and extends below the liquid level in the farmland.
[0044] Working principle:
[0045] After fixing the water storage tank 1, the height of the prefabricated buoy 6 is set. At this time, the overall force on the buoy 6 tends to be balanced. When the water level changes, the buoy 6 drives the connecting pipe 5 to move, and the connecting pipe 5 drives the clamping plate 7 to move as well. The clamping plate 7 contacts the switch 8. When the water level rises, the uppermost switch 8 controls the cam rotor pump 2 to suck water into the water storage tank 1. Similarly, when the water level drops, the lowermost switch 8 controls the cam rotor pump 2 to discharge water into the farmland.
[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
