[0002] The growth of crops is inseparable from the climate environment. Real-time monitoring of environmental changes and accurate grasp of farming time are crucial to agricultural production. If strong winds occur during harvesting of crops such as wheat, the wheat will fall over, resulting in reduced yields. Therefore, agricultural growers should pay close attention to the real-time changes in wind direction and speed. Therefore, wind speed and direction measuring equipment will be installed in farmland, which can effectively provide accurate data for agricultural production and reduce the impact of strong winds on farmland.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, when the outside air flows, it pushes the rotating plate to rotate. The greater the wind force, the faster the rotation speed of the rotating plate, and the more electric energy the generator generates. Conversely, the smaller the wind force of the outside air blowing onto the surface of the rotating plate, the slower the rotation speed of the rotating plate, and the less electric energy the generator generates. The staff can measure the outside wind speed according to the electric energy generated by the generator and the speed at which the battery pack stores electricity. A plurality of rotating plates are installed around the fixed cylinder. When the outside wind force blows toward the plurality of rotating plates on one side of the fixed cylinder, the other side of the fixed cylinder leeward cannot contact the wind force blowing toward the fixed cylinder, so the plurality of rotating plates on one side of the fixed cylinder rotate, while the plurality of rotating plates on the other side do not rotate. At the same time, the plurality of generators located on the inner wall of the second fixed circle will generate electricity on one side, while the plurality of generators on the other side cannot generate electricity. The staff can measure the outside wind direction through the transmission of the plurality of generators to the inside of the battery pack.

[0018] 2. In the present invention, the staff can use the electricity stored in the battery pack by installing the shaft to drive the fan blades to rotate. When the fan blades drive the fixed cylinder to move upward, the air from the outside entering the fixed cylinder will cool the surface of the battery pack and the generator through the installing cylinder during circulation, thereby preventing the battery pack from being seriously heated up due to the long-term power transmission to the battery pack by the generator and the external sunlight when the battery pack is in use. When the outside air flows inside the fixed cylinder, the flowing air can clean the inner wall of the fixed cylinder and the outer wall surface of the installing cylinder. At the same time, the fixed cylinder can be transferred to the designated position by the rotation of the fan blades, which is convenient for the staff to adjust the position of the fixed cylinder, and there is no need for the staff to go to the fixed cylinder placement position to change the position of the fixed cylinder in person.

[0019] 3. In the present invention, when the fixed cylinder is about to fall to the ground, the electric slider, the weight block and the support plate move downward, and the several weight blocks will move to the outer wall of the bottom end of the fixed cylinder. The several weight blocks can increase the weight of the bottom end of the fixed cylinder, so that the center of gravity of the fixed cylinder moves downward. When the fixed cylinder falls to the ground, the bottom end of the fixed cylinder can be made more stable, preventing the air flowing from the inside of the fixed cylinder to the ground from rising after contacting the ground and affecting the stability of the bottom end of the fixed cylinder. When the fixed cylinder falls to the ground, the bottom ends of the several support plates will contact the ground, and the several support plates cooperate with each other to provide better support for the fixed cylinder. The fixed cylinder, the first fixed ring and the second fixed ring are all located above the ground. When in use, the height of the fixed cylinder above the ground can be adjusted by the electric slider and the support plate, so that the air flowing from the outside can better blow the several rotating plates around the fixed cylinder.

[0020] 4. In the present invention, the staff can change the installation method of the fixed tube according to the usage situation. The staff can hook the fixed tube on the tree at the specified position through the protective frame on the first fixed ring, or hook the fixed tube on the fixed frame installed in advance. At the same time, several weight blocks are moved to the outer wall of the bottom end of the fixed tube through the electric slider. When the fixed tube is hooked and installed, the stability of the bottom end of the fixed tube can be improved to prevent the fixed tube from swaying in the air when in use. At the same time, when the fixed tube is hooked and installed, it can also prevent the fixed tube from tipping over and rolling, and it is convenient for the fixed tube and several rotating plates thereon to measure the wind speed and direction in the air at a higher position for a long time.

[0034] As a technical optimization scheme of the present invention, a plurality of limit grooves 28 are provided on the outer wall of the second fixed ring 3, and the top of the inner wall of the limit groove 28 passes through the second fixed ring 3. A plurality of slide grooves 10 matching the limit grooves 28 are provided on the outer wall of the fixed cylinder 1 in the length direction, and an electric slider 18 is slidably installed inside the slide groove 10, and a weight block 26 is installed at the end of the electric slider 18 away from the inner wall of the slide groove 10; the electric slider 18 can drive the support plate 7 to move downward, and the plurality of support plates 7 provide a good supporting effect on the fixed cylinder 1.

[0035] As a technical optimization solution of the present invention, the weight block 26 is located on the side of the fixed cylinder 1, and a support plate 7 is rotatably installed on the bottom end of the weight block 26. The bottom end of the support plate 7 passes through the limiting groove 28. A sliding hole 27 is opened on the side of the support plate 7 in the length direction. A support rod 20 is slidably installed inside the sliding hole 27. The two ends of the support rod 20 are respectively installed on the inner walls on both sides of the limiting groove 28; when in use, the support rod 20 can play a better position limiting role in the rotation of the support plate 7, so that the support plate 7 is more stable while supporting the fixed cylinder 1.

The bottom end of the rotating shaft 11 is connected to the speed increasing gear box 25, and the bottom block 5 is located between two adjacent support plates 7. When the rotating shaft 11 rotates, the gears inside the speed increasing gear box 25 can rotate rapidly, so that the speed increasing gear box 25 generates greater kinetic energy.

[0037] As a technical optimization solution of the present invention, a generator 14 is installed on the inner wall of the second fixed circle 3 near the corners, the end of the generator 14 away from the inner wall of the second fixed circle 3 is installed at the bottom of the fixed cylinder 1, and the top of the end of the generator 14 close to the inner wall of the second fixed circle 3 is installed at the bottom of the bottom block 5, and the generator 14 is connected to the speed-increasing gearbox 25; the generator 14 is connected to the speed-increasing gearbox 25, and the generator 14 can convert the kinetic energy generated by the speed-increasing gearbox 25 into electrical energy.

[0038] As a technical optimization solution of the present invention, a connecting hole 19 is opened at the middle end of the side of the two support frames 15, a second connecting plate 29 is installed at the top of the battery pack 13, a connecting groove 30 is opened at the top of the second connecting plate 29, and the bottom end of the mounting shaft 17 is rotatably mounted inside the connecting hole 19; the electric energy generated by the generator 14 is transmitted to the inside of the battery pack 13, and the battery pack 13 can store the electric energy.

[0039] As a technical optimization solution of the present invention, a connecting block 21 is installed at the bottom end of the mounting shaft 17, and the connecting block 21 is located inside the connecting groove 30. The connecting hole 19 located on the lower support frame 15 passes through the mounting tube 12. A first connecting plate 16 is installed at the bottom of the lower support frame 15, and the first connecting plate 16 is located at the bottom end of the connecting hole 19. The bottom end of the battery pack 13 is interconnected with the first connecting plate 16 through the connecting hole 19; the connecting hole 19 located on the upper support frame 15 can better limit the position of the bottom end of the mounting shaft 17.

[0040] As a technical optimization solution of the present invention, a protective frame 6 is installed on the top of the first fixed ring 2, and the protective frame 6 is located above the fixed tube 1. The top end of the mounting shaft 17 is rotatably installed on the inner top of the protective frame 6, and a plurality of fan blades 23 are all located inside the protective frame 6; when in use, the protective frame 6 can provide better protection for the fixed tube 1 and the plurality of fan blades 23, preventing external branches from falling into the interior of the fixed tube 1.

[0041] As a technical optimization solution of the present invention, several generators 14 are located at the top of the inner wall of the second fixing circle 3, and the first fixing circle 2 and the second fixing circle 3 are both polygonal frames; when in use, the second fixing circle 3 can provide better support for the fixing tube 1 to prevent debris on the ground from entering the interior of the fixing tube 1.

[0042] When the present invention is used, the staff installs a signal receiver inside the fixed cylinder 1, and connects several generators 14 to the first connecting plate 16, and the first connecting plate 16 is connected to the battery pack 13 located inside the mounting cylinder 12. The staff installs the first fixing ring 2 and the second fixing ring 3 at both ends of the fixed cylinder 1, and places the fixed cylinder 1 on the ground at a designated position in the farmland. When in use, the bottom of the second fixing ring 3 is in contact with the ground, and the fixed cylinder 1 is located above the ground. When the outside is windy, the wind will blow the two rotating plates 9 on the outer wall mounting sleeves 8 of several rotating shafts 11 around the fixed cylinder 1 to rotate. Because the bottom end of the rotating shaft 11 is connected to the inside of the speed-increasing gear box 25, when the rotating plate 9 rotates, its bottom end can drive the gear inside the speed-increasing gear box 25 to rotate, and the speed-increasing gear box 25 is connected to the generator 14, and the kinetic energy generated by the gear inside the speed-increasing gear box 25 after rapid rotation can be transmitted to the inside of the generator 14, and the generator 14 can convert the kinetic energy into electrical energy. When in use, the electric energy converted by the generator 14 is transmitted to the interior of the battery pack 13 through the first connecting plate 16 , and the electric energy is stored in the battery pack 13 .

[0043] When in use, the outside air can drive the rotating plate 9 to rotate when it flows. The greater the wind force, the faster the rotating plate 9 rotates, and the more electric energy the generator 14 generates. On the contrary, the smaller the wind force of the outside air blowing to the surface of the rotating plate 9, the slower the rotating plate 9 rotates, and the less electric energy the generator 14 generates. The staff can measure the outside wind speed according to the electric energy generated by the generator 14 and the speed of the battery pack 13 storing electricity. A plurality of rotating plates 9 are installed around the fixed cylinder 1. When the outside wind blows to the plurality of rotating plates 9 on one side of the fixed cylinder 1, the other side of the fixed cylinder 1 that is leeward cannot contact the wind force blowing in the direction of the fixed cylinder 1, so the plurality of rotating plates 9 on one side of the fixed cylinder 1 rotate, while the plurality of rotating plates 9 on the other side do not rotate. At the same time, the plurality of generators 14 located on the inner wall of the second fixed ring 3 will also generate electricity on one side, while the plurality of generators 14 on the other side cannot generate electricity. The staff can measure the outside wind direction through the transmission of the plurality of generators 14 to the inside of the battery pack 13.

[0044] When the staff needs to move the position of the fixed cylinder 1, the battery pack 13 can drive the installation shaft 17 to rotate inside the protective frame 6 through the stored electrical energy, and the installation shaft 17 can drive a number of blades 23 to rotate inside the protective frame 6 through the fixed sleeve 22 on its outer wall. When the blades 23 rotate, they can drive the outside air to flow into the interior of the fixed cylinder 1, and drive the fixed cylinder 1, the first fixed ring 2 and the second fixed ring 3 to move upward, so that the first fixed ring 2 is off the ground. When in use, the staff can use the blades 23 to suspend the fixed cylinder 1 in the air for a short time, and can measure the wind speed at different positions in the air, to prevent the fixed cylinder 1 from being placed on the ground to measure the wind speed, because of the obstruction of rice fields, terrain and trees, resulting in large errors in wind speed measurement.

[0045] When the fan blades 23 drive the fixed cylinder 1 to move upward, the air from the outside that enters the fixed cylinder 1 will cool the surface of the battery pack 13 and the generator 14 through the mounting cylinder 12 during circulation, preventing the battery pack 13 from being seriously heated due to the long-term power transmission from the generator 14 to the battery pack 13 and the external sun exposure during use. When the fixed cylinder 1 is measuring the wind speed on the ground, the dust from the outside will fall into the inside of the fixed cylinder 1 through the protective frame 6 and attach to the inner wall of the fixed cylinder 1 and the outer wall of the mounting cylinder 12. When the outside air flows inside the fixed cylinder 1, the flowing air can clean the inner wall of the fixed cylinder 1 and the outer wall of the mounting cylinder 12. The protective frame 6 located at the top of the first fixed ring 2 can provide better protection for the several fan blades 23 and the inside of the fixed cylinder 1 when in use, preventing large debris such as branches from the outside from entering the inside of the fixed cylinder 1 or causing collisions with the surface of the fan blades 23.

[0046] When in use, the staff can remotely control the fan blades 23 and the electric slider 18, which is convenient for the staff to remotely change the position of the fixed cylinder 1 according to the use situation, without the need for the staff to personally go to the installation position of the fixed cylinder 1 to change the position of the fixed cylinder 1. The staff drives the fixed cylinder 1 to move up through the fan blades 23, and drives the fixed cylinder 1 to move to other higher positions. When the fixed cylinder 1 falls to the ground, and when the fixed cylinder 1 is about to fall to the ground, several electric sliders 18 can drive the weight block 26 to move down, and at the same time drive the support plate 7 to slide inside the limit groove 28. When in use, the limit groove 28 will gradually move to the bottom of the second fixed ring 3 with the movement of the electric slider 18. At the same time, when the support plate 7 moves down, the bottom ends of several support plates 7 will rotate in the direction away from the fixed cylinder 1 with the support rod 20 as the center.

[0047] When the electric slider 18 moves downward, several weight blocks 26 will move to the outer wall of the bottom end of the fixed cylinder 1. Several weight blocks 26 can increase the weight of the bottom end of the fixed cylinder 1, so that the center of gravity of the fixed cylinder 1 moves downward. When the fixed cylinder 1 falls to the ground, the bottom end of the fixed cylinder 1 can be made more stable, preventing the air flowing from the inside of the fixed cylinder 1 to the ground from rising after contacting the ground and affecting the stability of the bottom end of the fixed cylinder 1. When in use, the bottom ends of several support plates 7 are respectively distributed around the bottom of the fixed cylinder 1. When the fixed cylinder 1 falls to the ground, the bottom ends of several support plates 7 will contact the ground. Several support plates 7 cooperate with each other to provide better support for the fixed cylinder 1. The fixed cylinder 1, the first fixed ring 2 and the second fixed ring 3 are all located above the ground. When in use, the height of the fixed cylinder 1 above the ground can be adjusted by the electric slider 18 and the support plate 7, so that the air flowing from the outside can better blow the several rotating plates 9 around the fixed cylinder 1.

[0048] During use, the staff can change the installation method of the fixed tube 1 according to the usage situation. The staff can hook the fixed tube 1 on the tree at the specified position through the protective frame 6 on the first fixed ring 2, or hook the fixed tube 1 on the fixed frame installed in advance. At the same time, several weight blocks 26 are moved to the outer wall of the bottom end of the fixed tube 1 through the electric slider 18. When the fixed tube 1 is hooked and installed, the stability of the bottom end of the fixed tube 1 can be improved to prevent the fixed tube 1 from swaying in the air during use. At the same time, when the fixed tube 1 is hooked and installed, it can also prevent the fixed tube 1 from tipping over and rolling, and it is convenient for the fixed tube 1 and several rotating plates 9 thereon to measure the wind speed and direction in the air at a higher position for a long time.

[0049] 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. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
