DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] See also Figure 1-3 The utility model provides a portable water conservancy monitoring UAV, including a body 1, support arms 2, wings 3, a folding assembly 4 and a landing frame 5. There are four support arms 2, which are slidably installed at the four corners of the body 1 respectively, and the wings 3 are rotatably installed at the ends. A panoramic monitoring probe is provided at the bottom of the body 1. By setting the panoramic monitoring probe, water conservancy monitoring work can be carried out when the UAV is flying.

[0021] Reference Figure 1 and Figure 2 The folding assembly 4 is arranged in the body 1. The folding assembly 4 includes a bidirectional screw 41, a driving assembly 42, a connecting block 43 and a hinged rod 44. The bidirectional screw 41 is rotatably installed in the body 1, and the driving assembly 42 is installed in the middle of the bidirectional screw 41. The connecting block 43 is sleeved on the bidirectional screw 41 and is threadedly connected with the bidirectional screw 41. There are two connecting blocks 43, and the two connecting blocks 43 are symmetrically installed on the bidirectional screw 41. The hinged rod 44 is hinged between the connecting block 43 and the support arm 2. By setting the folding assembly 4, the driving assembly 42 can be used to rotate the bidirectional screw 41, so that the bidirectional screw 41 drives the connecting block 43 to slide along the bidirectional screw 41, and the connecting block 43 drives the support arm 2 to slide through the hinged rod 44. When the drone is not in use, the support arm 2 can be folded into the body 1 to reduce the space occupied by the support arm 2, so that it is easy to carry and store.

[0022] Specifically, the driving component 42 includes a knob 421, a worm 422 and a worm wheel 423. The knob 421 is fixedly connected to the upper end of the worm 422, the worm 422 is rotatably installed in the body 1, and the worm wheel 423 is fixedly installed on the bidirectional screw 41 and meshes with the worm 422. By setting the driving component 42, during operation, the knob 421 can be rotated so that the knob 421 drives the worm 422 to rotate, the worm 422 drives the worm wheel 423 to rotate, and the worm wheel 423 drives the bidirectional screw 41 to rotate, which is convenient for operation; a groove 11 is provided on the top surface of the body 1, and a cover plate 12 is hinged on the top of the groove 11. The knob 421 is embedded in the groove 11. By setting the groove 11 and the cover plate 12, the knob 421 can be protected.

[0023] Furthermore, a limiting groove 21 is provided on the side wall of the support arm 2. By setting the limiting groove 21, the support arm 2 can be limited to improve the stability of the support arm 2. The inner wall of the fuselage 1 is fixedly connected to the limiting rod 45, and the end of the support arm 2 away from the wing 3 is fixedly connected to the limiting block 22. The limiting block 22 is slidably sleeved on the limiting rod 45. By setting the limiting block 22 and the limiting rod 45, the support arm 2 can be limited to prevent the support arm 2 from slipping out of the fuselage 1.

[0024] Reference Figure 1 and Figure 3 There are four landing stands 5, which are respectively installed at the four corners of the bottom of the body 1. The landing stands 5 include a telescopic rod 51, a spring 52, a rubber ball 53 and a limit bolt 54. The telescopic rod 51 is fixedly installed at the bottom of the body 1, the spring 52 is arranged in the telescopic rod 51, the rubber ball 53 is fixedly connected to the lower end of the telescopic rod 51, and the limit bolt 54 is inserted into the side wall of the telescopic rod 51. By setting the landing stand 5, when the drone is in use, the limit bolt 54 can be loosened. When the drone lands, the rubber ball 53 contacts the ground, the telescopic rod 51 can be retracted and retracted under force, and the spring 52 is used to buffer the impact when landing, so as to reduce the impact of the drone when landing. When the drone is not in use, the telescopic rod 51 can be squeezed and contracted, and the limit bolt 54 is used to resist the telescopic end of the telescopic rod 51 for limit fixing, thereby reducing the landing stand 5 for easy carrying.

[0025] The working principle and usage process of the utility model are as follows: first, by setting up a folding component 4, the driving component 42 can be used to rotate the bidirectional screw 41, so that the bidirectional screw 41 drives the connecting block 43 to slide along the bidirectional screw 41, and the connecting block 43 drives the support arm 2 to slide through the hinge rod 44. When the drone is not in use, the support arm 2 can be folded into the body 1, reducing the space occupied by the support arm 2, thereby making it easy to carry and store.
