[0034] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0035] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0036] At present, wind direction and wind speed sensors in my country are all installed on a ten-meter-high wind pole 10, and the bottom of the wind pole is fixed to the ground by a hinge. The installation of the wind pole and the maintenance and repair of the wind direction and wind speed sensors are all manually lowered and raised, which generally requires 3-5 people, is time-consuming and labor-intensive, inefficient, and unsafe.

[0037] A wind pole landing device of the present application includes a base 1 placed on the ground, a clamp assembly 21 for fixing the wind pole, and a landing assembly; the landing assembly is connected to the clamp assembly and is used to drive the clamp assembly 21 to drive the wind pole to be laid flat or erected.

[0038] like Figure 1 As shown, the lifting and lowering assembly includes a support arm 22, a triangular inclined plate 23, a telescopic assembly 24 and a driving part 25. The support arm 22 and the triangular inclined plate 23 are each provided with a pair, and the two ends of the support arm 22 are respectively hinged to the base 1 and the triangular inclined plate 23, the bottom of the telescopic assembly 24 is hinged to the base 1, and the top is hinged to the triangular inclined plate 23. The triangular inclined plate 23 is hinged to the hoop assembly 21.

[0039] More specifically, if Figure 2 , Figure 3 As shown, the telescopic assembly 24 includes a first support rod 241 hinged to the base 1, a second support rod 242 passing through the first support rod 241, and a connecting piece 243 fixed to the top of the second support rod 242. The connecting piece 243 is preferably T-shaped, and the vertical part is fixedly sleeved on the top of the second support rod 242. The driving part 25 is used to drive the second support rod 242 and the connecting piece 243 to rise or fall along the first support rod 241. By using the principle of a single-cylinder reverse support arm, the lifting and lowering of the second support rod 242 drives the support arm 22 to rotate around the hinge point with the base 1, thereby driving the wind rod to be laid flat or erected.

[0040] like Figure 2, Figure 3 As shown, the rotating shaft 231 fixedly connects a pair of triangular inclined plates 23, the connecting member 243 is located between the pair of triangular inclined plates 23, and the horizontal part of the connecting member 243 is movably mounted on the rotating shaft 231, that is, the connecting member 243 is pivotally connected to the rotating shaft 231, so that the triangular inclined plates 23 can rotate relative to the support arm 22 and the telescopic assembly 24.

[0041] The wind pole foundation is generally rectangular, with a hinge on one side of the foundation. The base 1 in the present application is fixedly connected to a wind pole connecting part 11, with threads at both ends of the hinge, and matching screw holes are provided at positions corresponding to the threads on the wind pole connecting part 11.

[0042] When the wind pole needs to be laid down to repair or replace the equipment on the wind pole, the second support rod 242 is first driven to rise along the first support rod 241 by the driving unit 25, and the support arm 22 rotates along the hinge point through the single-cylinder reverse support arm principle, so that the telescopic component 24 is perpendicular to the ground; the wind pole is then limited by the hoop assembly 21 and the wind pole connecting part 11 to effectively avoid the danger caused by the wind pole being offset, and then the lock between the wind pole foundation and the ground is released, and the driving unit 25 drives the second support rod 242 to descend along the first support rod 241, and the support arm 22 rotates in the opposite direction around the hinge point with the base 1 through the single-cylinder reverse support arm principle, thereby driving the wind pole to be laid down. The speed of the second support rod 242 rising and falling along the first support rod 241 is not less than 1 cm / s.

[0043] During the process of lowering the wind pole, the triangular inclined plate 23 rotates relative to the support arm 22, and the hoop assembly 21 can also rotate flexibly relative to the triangular inclined plate 23. Through relative rotation, the hoop assembly 21 can flexibly adjust the angle of the wind pole as the position of the wind pole changes during the process of lowering the wind pole, so that the rotation axis of the hoop assembly 21 and the rotation axis of the wind pole remain coaxial, that is, the hoop assembly 21 will not scratch the outer wall of the wind pole, and play a role in protecting the wind pole. Similarly, when the wind pole needs to be erected, the triangular inclined plate 23 can be flexibly rotated relative to the support arm 22, and the hoop assembly 21 can be flexibly rotated relative to the triangular inclined plate 23, so that the wind pole will not be subjected to additional force.

[0044] The present application controls the driving part 25 through a remote control device. When the driving part 25 drives the second support rod 242 to extend, the extension distance is not less than 20 cm. In addition, when the telescopic component 24 is perpendicular to the bottom surface, the height of the entire device reaches a maximum value, and the maximum height does not exceed 70 cm. At this time, the angle between the support arm 22 and the telescopic component is 30° to 45°. The wind pole landing device of the present application is small in size and light in weight, which is very suitable for carrying by engineering vehicles. It is also very convenient to use the device in the field.

[0045] like Figure 1 to Figure 5As shown, the base 1 is a frame structure, preferably a rectangle, and a recessed portion 12 is provided on the frame structure, and the recessed portion 12 is adapted to the telescopic assembly 24. When the telescopic assembly 24 is folded, the recessed portion 12 is used to store the telescopic assembly 24. A handle 13 is also fixedly connected to the frame structure, and at least two handles 13 are provided, which facilitates the staff to move the device.

[0046] The device is preferably made of square tube steel and threaded steel, which has low production cost and is anti-corrosive and rust-proof. When the wind pole is lowered or raised, the wind pole is effectively limited, which can effectively prevent the safety accident of the wind pole falling due to operating errors in the prior art. It is safe and reliable, has a simple structure and is easy to operate.

[0047] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
