DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 8 A mobile sprinkler irrigation unit sprinkler uniformity measuring device comprises a plurality of sprinkler heads 3, a bracket 1, a plurality of rectangular rods 14 and two reciprocating screw rods 2 (only one reciprocating screw rod 2 is shown in the figure), the two ends of the bracket 1 are respectively threadedly connected to the two reciprocating screw rods 2, the driving end of the servo motor is fixedly connected to one end of the reciprocating screw rod 2, a plurality of rain gauges 5 are fixedly connected to the bracket 1, each rain gauge 5 is provided with a sliding assembly, the sliding assembly comprises a sealing plate 21 slidably mounted inside the rain gauge 5, the lower end of the sealing plate 21 is rotatably connected to a support rod 11, two cams 22 are fixedly connected to the support rod 11, and the two cams 22 are 180 degrees apart, a plurality of covering assemblies, each covering assembly is used for protecting the rain gauge 5, the covering assembly comprises a covering plate 8 rotatably mounted on the rain gauge 5, a rotating shaft 18 is connected to the rain gauge 5 through a first torsion spring, and the covering plate 8 is fixedly connected to the rotating shaft 18.

[0019] There are multiple knocking components, each of which is used to speed up the flow of water droplets. Each knocking component includes a bending block 20 slidably mounted on the rain gauge 5. The bending block 20 is connected to the corresponding rotating shaft 18 through a pull rope 33. A moving block 25 is connected to the bending block 20 through a first spring 31. The end of the moving block 25 away from the support rod 11 is fixedly connected to the first knocking block 30.

[0020] A hydraulic cylinder 17 is fixedly installed on the bracket 1, and the driving end of the hydraulic cylinder 17 is fixedly connected to the cross plate 13. The lower end of each support rod 11 is rotatably connected to the cross plate 13. A second torsion spring 16 is sleeved on the support rod 11, and one end of the second torsion spring 16 is fixedly connected to the support rod 11, and the other end of the second torsion spring 16 is fixedly connected to the cross plate 13. When the hydraulic cylinder 17 is started and drives the cross plate 13 to move downward, under the transmission action of each support rod 11, each sealing plate 21 will move downward in each rain gauge 5.

[0021] A rectangular block 28 is fixedly connected to the lower surface of each sealing plate 21, a knocking rod 29 is fixedly connected to each moving block 25, an opening 27 for connecting the knocking rod 29 is provided on the sealing plate 21, the cross-section of the rain gauge 5 is in a U-shape, and a rectangular opening connected to the rain gauge 5 is provided on the bracket 1. During the downward movement of the sealing plate 21, the lower surface of the rectangular block 28 will fit the upper surface of the bending block 20, and the upper end of the knocking rod 29 will extend into the opening 27. When the sealing plate 21 continues to move downward, the rectangular block 28 will move downward together with the upper surface of the bending block 20, and the bending block 20 can move up and down. The bending block 20 and the moving block 25 are both made of lightweight plastic material.

[0022] A measuring tube 26 is fixedly connected to one side of each rain gauge 5, and a water outlet is provided on the rain gauge 5. A scale plate 6 is fixedly connected to one side of the measuring tube 26. The scale plate 6 and the measuring tube 26 are both made of transparent glass. A sealing cover 7 is clamped on the measuring tube 26. An air bag 23 is fixedly connected to each rain gauge 5. A pressure tank 10 is fixedly connected to each measuring tube 26. A one-way valve is provided on the pressure tank 10 and the air bag 23. The pressure tank 10 and the air bag 23 are connected. A plurality of jet pipes 19 are fixedly connected to the upper inner wall of each measuring tube 26. The one-way valve can prevent the gas inside the pressure tank 10 from flowing back into the air bag 23. After the air bag 23 is squeezed by the moving block 25, the gas will be discharged into the pressure tank 10 for collection. When the valve of the pressure tank 10 is opened, the gas inside the pressure tank 10 will be discharged through each jet pipe 19. After the gas is ejected, the falling speed of the water droplets attached to the inner wall of the measuring tube 26 will be accelerated.

[0023] A color plate 32 is slidably connected in each measuring tube 26, and two second springs 4 are fixedly connected to the lower surface of the color plate 32. Each second spring 4 is fixedly connected to the lower inner wall of the measuring tube 26. When water flows onto the upper surface of the color plate 32, the color plate 32 will move downward, and the second spring 4 will be deformed. According to the corresponding scale positions on the color plate 32 and the scale plate 6, the rainfall value can be quickly obtained to facilitate the subsequent measurement of the uniformity of the sprinkler irrigation. The sealing cover 7 can be opened to take out the water flow inside the measuring tube 26.

[0024] A plurality of fixed plates 15 are fixedly connected to each rectangular rod 14, and the plurality of fixed plates 15 are equidistantly arranged. A rotating plate 24 is fixedly connected to each support rod 11, and the rotating plate 24 can pass through the rectangular opening. When each rotating plate 24 moves together with the bracket 1, the rotating plate 24 will move against the fixed plate 15, and the rotating plate 24 will rotate at the same time. After the rotating plate 24 and the fixed plate 15 are separated, the rotating plate 24 will rotate to the initial angle under the elastic force of the second torsion spring 16. A mounting rod 12 is fixedly connected to each first knocking block 30, and a second knocking block 9 is fixedly connected to one end of the mounting rod 12. When the moving block 25 and the bending block 20 slide relative to each other, the moving block 25 will squeeze the airbag 23, and the first knocking block 30 will separate from the surface of the rain gauge 5 at the same time. Under the transmission action of the mounting rod 12, the second knocking block 9 will hit the surface of the pressure tank 10 and the measuring tube 26.

[0025] In the present invention, in the initial state, each covering plate 8 is horizontally arranged and covers the upper surface of the corresponding rain gauge 5 respectively, which can effectively prevent impurities from entering the rain gauge 5. When in use, the hydraulic cylinder 17 is started and drives the cross plate 13 to move downward. Under the transmission action of each support rod 11, each sealing plate 21 moves downward in each rain gauge 5 at the same time. The surface of the sealing plate 21 that fits the inner wall of the rain gauge 5 is provided with a rubber pad, which can not only improve the sealing performance when the sealing plate 21 and the rain gauge 5 are connected, but also when the sealing plate 21 moves downward, the rubber pad will move downward close to the inner wall of the rain gauge 5, so as to scrape off the impurities remaining on the inner wall of the rain gauge 5, which is beneficial to reduce the error during measurement.

[0026] During the downward movement of the sealing plate 21, since the rectangular block 28 is fixedly connected to the sealing plate 21, and part of the surface of the bending block 20 is located directly below the rectangular block 28 (as shown in the attached Figure 5 As shown in the figure, the lower surface of the rectangular block 28 will fit with the upper surface of the bending block 20, and the upper end of the knocking rod 29 will extend into the opening 27. The two cams 22 are located on the opposite side of the moving block 25. In the subsequent forward or reverse rotation of the support rod 11, a cam 22 will squeeze the moving block 25. When the sealing plate 21 moves downward, the rectangular block 28 will move downward together with the upper surface of the bending block 20. Under the transmission action of the inelastic pull rope 33, the rotating shaft 18 will rotate relative to the rain gauge 5, thereby driving the covering The cover plate 8 rotates together, and the cover plate 8 is set obliquely downward after rotation, that is, it no longer blocks the surface of the rain gauge 5, which can prevent water drops on the cover plate 8 from flowing into the rain gauge 5. Since one end of the first torsion spring is fixedly connected to the rotating shaft 18, and the other end is fixedly connected to the surface of the rain gauge 5, the first torsion spring is deformed at the same time, thereby realizing the automatic opening of the cover plate 8. Under the protective effect of the cover plate 8, impurities can be effectively prevented from entering the rain gauge 5, so as to reduce the error during measurement, which is beneficial to the measurement of sprinkler irrigation uniformity.

[0027] When the sealing plate 21 moves down a certain distance, the hydraulic cylinder 17 stops working. At this time, the sealing plate 21 is completely located on the side opposite to the water outlet. At this time, the rotating piece 24 is located between the two fixed pieces 15. Then the motor drives the reciprocating screw 2 to rotate, and each nozzle 3 sprays clean water at the same time. During the movement of the bracket 1 back and forth along the reciprocating screw 2, the sprayed water flow will fall into each rain gauge 5. During the movement of each rotating piece 24 together with the bracket 1, the rotating piece 24 will move against the fixed piece 15. Since the position of the rectangular rod 14 cannot be changed, the fixed piece 15 is fixedly connected to the rectangular rod 14, and the fixed piece 15 cannot move. When the rotating piece 24 moves against the surface of the fixed piece 15, the rotating piece 24 will rotate around the axis of the support rod 11 under the blocking effect of the fixed piece 15, and the support rod 11 fixedly connected to the rotating piece 24 will also rotate together, that is, the support rod 11 rotates (as shown in the attached figure). Figure 2 As shown), since the hydraulic cylinder 17 is fixedly mounted on the bracket 1, the driving end of the hydraulic cylinder 17 is fixedly connected to the cross plate 13, and the lower end of the support rod 11 is rotatably connected to the cross plate 13. During the rotation of the support rod 11, it will rotate relative to the cross plate 13. Since the cam 22 is fixedly connected to the support rod 11, the cam 22 will rotate, and the corresponding cam 22 will squeeze the moving block 25, so that the moving block 25 and the bending block 20 slide relative to each other. Since one end of the first spring 31 is fixedly connected to the bending block 20, and the other end is fixedly connected to the moving block 25, the first spring 31 is deformed.

[0028] In the initial state, the surface of the first knocking block 30 is in contact with the surface of the rain gauge 5. During the relative sliding of the moving block 25 with a T-shaped cross section and the bending block 20, the moving block 25 will squeeze the airbag 23, and the first knocking block 30 will be separated from the surface of the rain gauge 5 at the same time. The knocking rod 29 will hit the inner wall of the opening 27. Since one end of the mounting rod 12 is fixedly connected to the first knocking block 30, and the other end of the mounting rod 12 is fixedly connected to the second knocking block 9, the first knocking block 30 is fixedly connected to the moving block 25, and the first knocking block 30 moves with the moving block 2 5 moves together, the mounting rod 12 will move together and drive the second knocking block 9 to move, the second knocking block 9 will hit the surface of the pressure tank 10 and the measuring cylinder 26, the sealing plate 21 will vibrate so that the water droplets slide along the inclined surface into the measuring cylinder 26, and the measuring cylinder 26 will vibrate so that the water droplets on the inner wall of the measuring cylinder 26 will fall quickly. When the rotating piece 24 and the fixing piece 15 are separated, under the elastic force of the second torsion spring 16, the rotating piece 24 will rotate to the initial angle, and the protrusion 22 will not squeeze the moving block 25 when it rotates to the initial position (as shown in the attached Figure 2As shown), under the elastic force of the first spring 31, the moving block 24 and the first knocking block 30 will move to the initial position, and the first knocking block 30 will hit the surface of the rain gauge 5 when moving until it fits with the surface of the rain gauge 5, so that the water droplets adhered to the inner wall of the rain gauge 5 flow to the inclined surface of the sealing plate 21 with a right-angle trapezoidal cross-section. The inclined surface of the sealing plate 21 is relatively smooth, so that the water droplets can slide into the measuring tube 26, which can better and more thoroughly collect the water flow inside the rain gauge 5, so as to reduce errors. The cross-sectional area of ​​the measuring tube 26 is smaller than that of the rain gauge 5, which is conducive to improving the accuracy of rainfall measurement.

[0029] The one-way valve can prevent the gas inside the pressure tank 10 from flowing back into the airbag 23. After the airbag 23 is squeezed by the moving block 25, the gas will be discharged into the pressure tank 10 for collection. When the nozzle 3 stops spraying for a period of time, the valve of the pressure tank 10 is opened, and the gas inside the pressure tank 10 will be discharged through each jet pipe 19. After the gas is sprayed out, it will accelerate the falling of water droplets attached to the inner wall of the measuring tube 26. When the water falls on the upper surface of the color plate 32, the color plate 32 will move down, and the second spring 4 will be deformed. According to the corresponding scale positions on the color plate 32 and the scale plate 6, the rainfall value can be quickly obtained to facilitate the subsequent measurement of the uniformity of the sprinkler irrigation.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
