The utility model can connect the circuit connected to the signal transmitter in a water location by setting a measuring probe and an input probe, so as to facilitate real-time monitoring of whether different areas of the farmland are irrigated with water flow, thereby improving measurement efficiency.

[0004] The arrangement of the connecting rod and the arc plate in the above device can utilize the pressure on the arc plate to move upward, allowing the connecting rod to slide in the slide groove thereon to spread out the multiple arc plates, thereby facilitating the pushing away of soil impurities at the position to be detected. However, if the soil is relatively moist, the thrust of the soil on the arc plate may be smaller than the elastic force of the spring, making it impossible for the multiple arc plates to be spread out, and then the measuring probe cannot detect.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The arrangement of the connecting rod and the arc plate in the above device can utilize the pressure on the arc plate to move upward, allowing the connecting rod to slide in the slide groove thereon to spread out the multiple arc plates, thereby facilitating the pushing away of soil impurities at the position to be detected. However, if the soil is relatively moist, the thrust of the soil on the arc plate may be smaller than the elastic force of the spring, making it impossible for the multiple arc plates to be spread out, and then the measuring probe cannot detect.

[0033] Embodiment 1:

[0034] like Figures 1 to 5 The utility model provides an unmanned aerial vehicle irrigation measurement device.

[0035] Specifically, by Figure 1-2A drone irrigation measurement device is provided, comprising a base plate 1, an L-shaped connecting rod 15, and an installation frame 11. Two detection components 2 are installed on the installation frame 11. The detection component 2 comprises a detection rod 201. A plug 211 is installed at the bottom end of the detection rod 201. A connection plate 203 is rotatably connected to the top end of the detection rod 201. A rotating shaft 202 is connected to the connection plate 203. The connection plate 203 is rotatably connected to the rotating shaft 202. The end of the connection plate 203 away from the detection rod 201 is rotatably connected to a pressure rod 201. 4. The bottom end of the pressure rod 204 is fixedly connected with a moving block 205, and the outer wall of the pressure rod 204 is provided with a spring 206 and a first mounting block 207. The spring 206 is fixedly installed between the connecting plate 203 and the first mounting block 207. The outer wall of the first mounting block 207 is rotatably connected with a plurality of support rods 208, and the support rods 208 are rotatably connected with connecting rods 209. One end of the connecting rod 209 away from the support rod 208 is rotatably connected to the moving block 205, and a measuring probe 210 is fixedly installed at the bottom of the support rod 208.

[0036] The staff controls the drone to fly above the land where irrigation measurement is required, and the telescopic end of the electric telescopic rod 13 moves downward, so that the plug 211 and the detection rod 201 are vertically pushed into the land. At this time, the detection rod 201 can better measure the thickness of soil moisture. By measuring the depth of soil moisture, farmers can understand the soil moisture conditions in different areas of the farmland, and thus decide whether irrigation is needed, the amount of irrigation and the time of irrigation, so as to avoid over-irrigation or under-irrigation and improve irrigation efficiency.

[0037] The telescopic end of the electric telescopic rod 13 continues to move downward. After the plug 211 contacts the relatively dry soil, the right end of the connecting plate 203 is lifted upward due to the resistance of the hard soil, and the left end of the connecting plate 203 drops. The spring 206 is compressed by the external force, and the connecting plate 203 pushes the moving block 205 downward through the pressure rod 204. The moving block 205 pushes the support rod 208 to open through the connecting rod 209, so that the measuring probe 210 at the bottom of the support rod 208 measures the irrigation conditions of the ground surface. Detecting the humidity of the soil surface can understand the irrigation conditions in different areas, facilitate the control of the amount of irrigation water for farmland, improve the measurement efficiency, and ensure the irrigation effect.

[0038] Further:

[0039] like Figure 2 It is shown that two fixing blocks 10 are fixedly installed on the top of the first mounting block 207, and one end of the fixing block 10 away from the first mounting block 207 is fixedly installed on the inner wall of the mounting frame 11. The two fixing blocks 10 are symmetrically arranged, and one end of the rotating shaft 202 away from the connecting plate 203 is fixedly installed on the mounting frame 11.

[0040] Since the first mounting block 207 is connected to the inner wall of the mounting frame 11 through two fixing blocks 10, this can ensure that the connection between the first mounting block 207 and the mounting frame 11 is more stable. This stability is particularly important when the device is running, and can reduce looseness or damage caused by vibration or external forces. The two fixing blocks 10 are symmetrically arranged. This symmetry not only makes the structure more beautiful, but also ensures the balance of the device during operation. The symmetrical structure helps to reduce distortion or deformation caused by uneven force, thereby extending the service life of the device.

[0041] Further:

[0042] like Figure 1 It is shown that two first connecting rods 12 are installed on the top of the installation frame 11, and one end of the first connecting rod 12 away from the installation frame 11 is fixedly installed on the outer wall of the L-shaped connecting rod 15, and the shape of the plug 211 is set to be conical.

[0043] This connection method enhances the connection strength between the mounting frame 11 and the L-shaped connecting rod 15, and improves the stability of the overall structure. When the device is subjected to external force or vibration, this structure can effectively reduce the risk of deformation or damage. The shape of the plug 211 is set to be conical, and the conical plug 211 is easier to insert into the ground, reducing the resistance when plugging and unplugging.

[0044] like Figure 1 It is shown that two second mounting blocks 3 are fixedly mounted on the top of the base plate 1, and the two second mounting blocks 3 are symmetrically arranged. An electric telescopic rod 13 is fixedly mounted on the bottom of the base plate 1, and the telescopic end of the electric telescopic rod 13 is connected to a round block 7, which is mounted on one end of an L-shaped connecting rod 15 away from the mounting frame 11.

[0045] The base plate 1 can be fixed under the drone by the second mounting block 3. The symmetrical arrangement of the two second mounting blocks 3 not only enhances the balance of the overall structure, but also improves the stability of the second mounting blocks 3 installed under the drone. The telescopic end of the electric telescopic rod 13 can easily push the detection rod 201 and the plug 211 into the soil. The round block 7 can easily transport water to the second telescopic water pipe 8 inside the L-shaped connecting rod 15.

[0046] Further:

[0047] like Figure 1-2 It is shown that a limit block 16 is fixedly installed on one side of the installation frame 11 . The limit block 16 is sleeved on the outer wall of the detection rod 201 . The detection rod 201 is slidably connected to the limit block 16 . The limit block 16 is arranged below the connecting plate 203 .

[0048] The limit block 16 is sleeved on the outer wall of the detection rod 201 to ensure that the detection rod 201 remains stable during movement without shaking or deviating from the predetermined path. The setting of the limit block 16 can also prevent the detection rod 201 from being impacted or damaged by excessive external force.

[0049] like Figure 1 It is shown that a water tank 4 is fixedly installed on the top of the base plate 1, a first telescopic water pipe 6 is fixedly installed on the bottom of the water tank 4, an electric water valve 5 is installed on the first telescopic water pipe 6, an end of the first telescopic water pipe 6 away from the water tank 4 is fixedly installed on a round block 7, two second telescopic water pipes 8 are fixedly connected to the round block 7, and a nozzle 9 is fixedly installed on the end of the second telescopic water pipe 8 away from the round block 7.

[0050] After the measuring probe 210 has finished detecting, stains may adhere to the surface of the measuring probe 210. At this time, the electric water valve 5 is started, and the water in the water tank 4 flows along the first telescopic water pipe 6 to the round block 7, and then passes through the second telescopic water pipe 8 in the L-shaped connecting rod 15 and is sprayed out from the nozzle 9. The sprayed water is sprayed radially, which can better clean the measuring probe 210 and better prevent the stains from affecting the sensitivity of the subsequent detection of the measuring probe 210.

[0051] Further:

[0052] like Figure 1 and Figure 3 It is shown that a sealing cover 14 is threadedly connected to the top of the water tank 4 , the water tank 4 is arranged in the middle of the base plate 1 , and the electric water valve 5 is fixedly installed at the bottom of the base plate 1 .

[0053] The sealing cover 14 allows the user to easily open and close the water tank 4, thereby facilitating cleaning, adding water or other maintenance operations on the water tank 4. At the same time, the threaded connection also ensures a tight connection between the sealing cover 14 and the water tank 4, preventing water leakage. The water tank 4 is arranged in the middle of the base plate 1 to help balance the center of gravity of the device and reduce the risk of overturning of the base plate 1 due to the shift of the center of gravity.

[0054] like Figure 1 It is shown that the round block 7 and the L-shaped connecting rod 15 are both set to be hollow, the second telescopic water pipe 8 is set inside the L-shaped connecting rod 15, and the nozzle 9 is set on the installation frame 11 and is set below the moving block 205.

[0055] The L-shaped connecting rod 15 is hollow and a second telescopic water pipe 8 is arranged inside, which can make full use of the space and make the overall structure more compact. The hollow design can play a protective and heat-insulating role to a certain extent. The hollow structure can reduce the direct impact of the external environment on the internal second telescopic water pipe 8 and extend its service life.

[0056] Working principle: The staff controls the drone to fly above the land where irrigation needs to be measured, and the telescopic end of the electric telescopic rod 13 moves downward, so that the plug 211 and the detection rod 201 are vertically pushed into the land. At this time, the detection rod 201 can better measure the thickness of the wet land. By measuring the depth of soil wetness, farmers can understand the soil moisture conditions in different areas of the farmland, and thus decide whether irrigation is needed, the amount of irrigation and the time of irrigation, avoid over-irrigation or under-irrigation, and improve irrigation efficiency.

[0057] The telescopic end of the electric telescopic rod 13 continues to move downward. After the plug 211 contacts the relatively dry soil, the right end of the connecting plate 203 is lifted upward due to the resistance of the hard soil, and the left end of the connecting plate 203 drops. The spring 206 is compressed by the external force, and the connecting plate 203 pushes the moving block 205 downward through the pressure rod 204. The moving block 205 pushes the support rod 208 to open through the connecting rod 209, so that the measuring probe 210 at the bottom of the support rod 208 measures the irrigation conditions of the ground surface. Detecting the humidity of the soil surface can understand the irrigation conditions in different areas, facilitate the control of the amount of irrigation water for farmland, improve the measurement efficiency, and ensure the irrigation effect.

[0058] After the measuring probe 210 has finished detecting, stains may adhere to the surface of the measuring probe 210. At this time, the electric water valve 5 is started, and the water in the water tank 4 flows along the first telescopic water pipe 6 to the round block 7, and then passes through the second telescopic water pipe 8 in the L-shaped connecting rod 15 and is sprayed out from the nozzle 9. The sprayed water is sprayed radially, which can better clean the measuring probe 210 and better prevent the stains from affecting the sensitivity of the subsequent detection of the measuring probe 210.

[0059] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
