Description

Technical Field

[0001] The invention relates to the technical field of data acquisition, and in particular to a data acquisition device for irrigation control. Background Art

[0002] Precise irrigation control can ensure that crops get the right amount of water, avoiding water waste, soil salinization and pest breeding caused by over-irrigation, and preventing growth stagnation, yield reduction and even death of crops caused by insufficient irrigation. To achieve effective irrigation control, accurate collection of irrigation-related data is a key link.

[0003] However, the collection of irrigation data in actual applications will be affected by many factors. First, since most of the outdoor farmland is uneven, the pipeline cannot be laid flat, resulting in a level difference between the pipeline and the flow meter, which may cause the water to flow unstable inside the pipeline, which may lead to the measurement accuracy of the flow meter. Secondly, the deformation and bending of the pipeline may increase the local resistance and uneven distribution of water flow velocity, thereby causing deviations in the measurement results of the flow meter. In addition, in open areas, especially in areas with large temperature differences, thermal expansion and contraction will also have an adverse effect on the water pipe. In an environment with large temperature changes, the water pipe may expand. At this time, the outer wall of the water pipe is subjected to additional stress, which may cause the water pipe to rupture during repeated use. This not only affects the normal operation of the irrigation system, but also poses a threat to the measurement accuracy and stability of the flow meter. Summary of the invention

[0010] As a preferred implementation, an extension rod is fixedly connected to the inner bottom of the second fixing frame, and a telescopic end of the extension rod is fixedly connected to the inner top wall of the first fixing frame.

[0011] The beneficial effect of adopting the above further solution is: by setting the extension rod, it is convenient to limit the relative position between the first fixing frame and the second fixing frame, thereby avoiding the relative position between the first fixing frame and the second fixing frame changing during adjustment or use, which leads to an increase in the workload of the staff.

[0012] As a preferred implementation, a limiting groove is provided on the inner side wall of the support plate, a limiting block is fixedly connected to the outer side wall of the support plate, and the outer side wall of the limiting block fits with the inner side wall of the limiting groove.

[0013] The beneficial effect of adopting the above further solution is that by providing the limiting groove and the limiting block, the length of the support plate can be easily adjusted, so that the support plate can be adjusted along with the adjustment of the first fixing frame during use.

[0021] By using the support seat, mounting groove, sponge strip and rubber strip in coordination, a buffer space can be provided for the pipeline to avoid thermal expansion and contraction of the pipeline under different temperature conditions, thereby preventing the outer wall of the pipeline from being restricted by the support seat when expanding due to heat and being subjected to additional stress, thereby preventing pipeline deformation from affecting the horizontality and measurement accuracy of the pipeline.

[0022] By using the connecting pipe, external water pipe, guide plate, rotating shaft and spiral blade in coordination, it is convenient to change the flow state of water when it enters the mounting seat, so as to avoid excessive water pressure when the water enters the mounting seat, which causes the spiral blade to be unable to rotate, thereby avoiding omissions when the flow meter body collects data, thereby improving the accuracy of data collection.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 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. Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the present invention provides a technical solution: a data acquisition device for irrigation control, comprising a mounting seat 1, and a balancing structure 2 is provided on the outer side wall of the mounting seat 1; The inner side wall of the mounting seat 1 is provided with a flow guide structure 3; The balancing structure 2 includes a first fixing frame 201 attached to the outer wall of the mounting base 1, the top of the first fixing frame 201 is rotatably connected with a threaded sleeve 207, the inner wall of the first fixing frame 201 is slidably connected with a threaded rod 204, the inner wall of the threaded sleeve 207 is threadedly connected to the threaded rod 204, and the bottom of the threaded rod 204 is fixedly connected with a second fixing frame 206. When the operator rotates the threaded sleeve 207, since the positions of the threaded sleeve 207 and the first fixing frame 201 are relatively fixed, the threaded sleeve 207 will move along the threaded rod 204 when rotating, thereby driving the position of the first fixing frame 201 to move. When the distance between the first fixing frame 201 and the second fixing frame 206 gradually decreases, The first fixing frame 201 and the second fixing frame 206 clamp the mounting base 1 to install the device. The outer wall of the first fixing frame 201 is fixedly connected with a first connecting rod 208. Two first connecting rods 208 are provided. The two first connecting rods 208 are respectively located at two ends of the outer wall of one side of the first fixing frame 201. The outer wall of the second fixing frame 206 is fixedly connected with a second connecting rod 209. Two second connecting rods 209 are provided. The positions of the two second connecting rods 209 correspond to the positions of the two first connecting rods 208. The outer walls of the two first connecting rods 208 are fixedly connected with extrusion rods 211. The two extrusion rods 211 are away from one of the two first connecting rods 208. The two ends of the two second connecting rods 209 are provided with an inclined angle, the outer side walls of the two second connecting rods 209 are provided with a sliding groove 210, and the outer side walls of the two second connecting rods 209 are fixedly connected with a support plate 214. The two second connecting rods 209 are respectively slidably connected with a moving block 212 through the two sliding grooves 210. The tops of the two moving blocks 212 are provided with an inclined angle, and the tops of the two moving blocks 212 are respectively matched with the bottoms of the two extrusion rods 211. When the first fixing frame 201 moves toward the second fixing frame 206, driving the two first connecting rods 208 to approach the two second connecting rods 209, the bottoms of the two extrusion rods 211 respectively conflict with the tops of the two moving blocks 212, thereby The position of the moving block 212 is adjusted, the outer side walls of the two moving blocks 212 are fixedly connected with a self-locking telescopic rod 213, the telescopic end of the self-locking telescopic rod 213 is fixedly connected with a moving joint 215, the bottom of the moving joint 215 is slidably connected to the top of the support plate 214, the outer side wall of the moving joint 215 is rotatably connected with a connecting rod 216, and the end of the connecting rod 216 away from the moving joint 215 is rotatably connected with a support seat 217, and the self-locking telescopic rod 213, the moving joint 215, the connecting rod 216, and the support seat 217 are respectively provided in a group, and a group of self-locking telescopic rod 213, the moving joint 215, the connecting rod 216, and the support seat 217 are respectively symmetrically distributed on the central axis plane of the support seat 217; When in use, the threaded sleeve 207 rotates and moves along the threaded rod 204, thereby driving the position of the first fixing frame 201 to move. When the distance between the first fixing frame 201 and the second fixing frame 206 gradually decreases, the first fixing frame 201 and the second fixing frame 206 clamp the mounting base 1, thereby installing the device. During the movement of the first fixing frame 201, the first fixing frame 201 drives the two first connecting rods 208 to move toward the directions of the two second connecting rods 209, thereby driving the two extrusion rods 211 to respectively contact the tops of the two moving blocks 212. Under the action of the two extrusion rods 211, the two moving blocks 212 slide toward the direction close to the support seat 217. At this time, the two moving blocks 212 push the self-locking telescopic rods 213 to move synchronously, and then the two self-locking telescopic rods 213 adjust the positions of the two moving joints 215. When the two moving joints 215 are close to each other, they will push one end of the two connecting rods 216 to lift. Because one end of the two connecting rods 216 is rotatably connected to the outer wall of the support seat 217, when one end of the two connecting rods 216 is lifted, the height of the support seat 217 will be adjusted, so that the outer wall of the support seat 217 fits with the outer wall of the pipeline, supporting the pipeline, so that the pipeline and the mounting seat 1 are in a relatively horizontal position, thereby reducing the position of the pipeline and the influence of the angle on the data acquisition accuracy.

[0027] like Figure 5 As shown: the outer wall of the support seat 217 is provided with a mounting groove 220, the mounting groove 220 is in an I-shape, the support seat 217 is detachably connected with a rubber strip 222 through the mounting groove 220, the rubber strip 222 is located inside the mounting groove 220, and the outer wall of the rubber strip 222 is matched with the inner wall of the mounting groove 220, and further the outer wall of the rubber strip 222 is fixedly connected with a sponge strip 221; During use, due to the temperature differences in different places, the pipeline is very likely to experience thermal expansion and contraction in places with large temperature differences, which may cause the pipeline to deform, thereby possibly changing the flow rate and flow state of the water flow inside the pipeline, which will in turn cause the data measurement and collection device to have large errors when collecting data. At the same time, when the pipeline expands due to heat, since the shape of the support seat 217 cannot be changed, when the pipeline expands due to heat, it is very easy for the support seat 217 to exert additional stress on the outer wall of the pipeline, thereby reducing the service life of the pipeline.

[0028] like Figure 3As shown: the inner wall of the first fixing frame 201 is fixedly connected with a return spring 202, and the first fixing frame 201 can be split. When the first fixing frame 201 is split into two parts, when the two parts of the first fixing frame 201 are pulled, the inner walls of the two parts of the first fixing frame 201 respectively squeeze the two return springs 202. At this time, the two return springs 202 pull and limit the distance between the two first fixing frames 201. When the first fixing frame 201 is completely attached to the outer wall of the device, the two parts of the first fixing frame 201 are loosened, and the two return springs 202 release their own elastic force to fix the two parts of the first fixing frame 201, so as to adapt to equipment of different sizes and sizes. The inner wall of the first fixing frame 201 is slidably connected with a connecting shaft 203, which is located at the center of the two return springs 202, and the two ends of the connecting shaft 203 are respectively located inside the two first fixing frames 201 to prevent the first fixing frame 201 from detaching during use.

[0029] like Figure 3 As shown: the inner bottom of the second fixing frame 206 is fixedly connected with an extension rod 205, and the telescopic end of the extension rod 205 is fixedly connected to the inner top wall of the first fixing frame 201. Since the first fixing frame 201 and the threaded rod 204 are slidably connected, when the operator rotates the threaded sleeve 207, the angle between the first fixing frame 201 and the second fixing frame 206 cannot be limited, which can easily cause the angle between the first fixing frame 201 and the second fixing frame 206 to shift, thereby reducing the stability of the equipment. At this time, the extension rod 205 limits the positions of the first fixing frame 201 and the second fixing frame 206, so that the relative angle between the first fixing frame 201 and the second fixing frame 206 remains consistent, thereby improving the stability of the equipment.

[0030] like Figure 6 As shown: the inner wall of the support plate 214 is provided with a limiting groove 218, and the support plate 214 is divided into two parts, and the two parts can move in opposite directions respectively. There are two limiting grooves 218, and the two limiting grooves 218 are both arranged on the outer wall of one part of the support plate 214, and the outer wall of the other support plate 214 is fixedly connected to the limiting block 219, and the two ends of the limiting block 219 are respectively located inside the two limiting grooves 218, and the outer wall of the limiting block 219 is matched with the inner wall of the limiting groove 218.

[0031] like Figure 1 and Figure 8As shown: the guide structure 3 includes a connecting pipe 301 fixedly connected to the mounting seat 1, and one end of the connecting pipe 301 away from the mounting seat 1 is fixedly connected to an external water pipe 302, and the inner wall of the connecting pipe 301 is fixedly connected to a guide plate 303, and three guide plates 303 are provided. The three guide plates 303 are distributed in a circular array on the inner wall of the connecting pipe 301, and the three guide plates 303 are all spiral. When water flows into the interior of the connecting pipe 301, the three guide plates 303 change the flow direction of the water flow, thereby buffering the water flow to a certain extent, avoiding excessive pressure of the water flow, which leads to a decrease in data measurement accuracy.

[0032] like Figure 8 As shown: one end of the three guide plates 303 is fixedly connected to the rotating shaft 304, and the outer wall of the rotating shaft 304 is rotatably connected to the spiral blade 305. When the water flows through the buffer of the three guide plates 303, the pressure drops, so that when the water flows through the spiral blade 305, it will drive the spiral blade 305 to rotate, thereby converting data such as the flow rate and flow of the water into data such as the rotation speed of the spiral blade 305, so as to collect the data more accurately and clearly. A flow meter body 306 is arranged on the top of the mounting seat 1, and one end of the flow meter body 306 is located inside the mounting seat 1. The flow meter body 306 located inside the mounting seat 1 is a sensor, which is convenient for recording and transmitting the rotation data of the spiral blade 305.

[0033] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the data acquisition device for irrigation control, when in use, connects the external water pipe 302 with the connecting pipe 301. Furthermore, when the threaded sleeve 207 is rotated, the threaded sleeve 207 moves along the threaded rod 204, thereby driving the position of the first fixing frame 201 to move. When the distance between the first fixing frame 201 and the second fixing frame 206 gradually decreases, the first fixing frame 201 and the second fixing frame 206 clamp the mounting seat 1, thereby installing the equipment. During the movement of the first fixing frame 201, the first fixing frame 201 drives the two first connecting rods 208 to move toward the directions of the two second connecting rods 209, thereby driving the two extrusion rods 211 to respectively contact the tops of the two moving blocks 212. Under the action of the two extrusion rods 211 , the two moving blocks 212 slide towards the direction close to the support seat 217 respectively, and at this time the two moving blocks 212 push the self-locking telescopic rods 213 to move synchronously, and then the two self-locking telescopic rods 213 adjust the positions of the two moving joints 215. When the two moving joints 215 are close to each other, they will push one end of the two connecting rods 216 to lift, and because one end of the two connecting rods 216 is rotatably connected to the outer wall of the support seat 217, when one end of the two connecting rods 216 is lifted, the height of the support seat 217 will be adjusted, so that the outer wall of the support seat 217 fits with the outer wall of the pipeline, supporting the pipeline, so that the pipeline and the mounting seat 1 are in a relatively horizontal position, thereby reducing the position of the pipeline, and the influence of the angle on the data acquisition accuracy; In areas with large temperature differences, pipes are very likely to experience thermal expansion and contraction in places with large temperature differences, which may cause deformation of the pipes, thereby changing the flow rate and flow state of the water flow inside the pipes, and further causing large errors in the data measurement and collection device when collecting data. At the same time, when the pipe expands due to heat, since the shape of the support seat 217 cannot be changed, when the pipe expands due to heat, it is very easy for the support seat 217 to apply additional stress to the outer wall of the pipe, thereby reducing the service life of the pipe. Therefore, when the pipe expands due to heat, the sponge strip 221 is first squeezed, and the rubber strip 222 further supports the pipe. Since the rubber strip 222 is made of rubber and has a certain elasticity, when the pipe squeezes the rubber strip 222, the rubber strip 222 relieves the pressure on the pipe to avoid additional stress on the outer wall of the pipe, thereby avoiding a decrease in the life of the pipe.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
