DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] In this embodiment, if Figure 1-Figure 6 As shown, a warning device for personnel approaching the aircraft air intake includes a base 101 and a camera 102. An infrared sensor light and an alarm are arranged on one side of the camera 102, so that when a person approaches, the infrared sensor light senses and transmits a signal to the camera 102, and the camera 102 takes a photo, which is convenient for finding the intruder later, making compensation or other subsequent operations. When the infrared sensor light senses that the person is close, the alarm warns and serves as a reminder. The camera 102 is arranged above the base 101, and a support rod 103 is fixedly installed on the upper end of the base 101. The upper end of the support rod 103 is fixedly connected There is a mounting plate 104, and also includes a warning mechanism 200 symmetrically arranged on both sides of the mounting plate 104, which is used to prevent people from approaching the aircraft air intake, a support mechanism 300 and a reeling mechanism 400. The support mechanism 300 is arranged on the outside of the base 101 to increase the structural stability of the device. The reeling mechanism 400 is arranged between the mounting plate 104 and the camera 102 to enhance the warning effect. Before the warning device for people approaching the aircraft air intake starts to be used, first check whether the device can be used normally, and then adjust the support mechanism 300 and the reeling mechanism 400 to make the device enter a ready-to-use state;

[0029] Among them Figure 2 and Figure 3 As shown, the warning mechanism 200 includes a horizontal plate 201 fixedly connected to the mounting plate 104, a sliding sleeve 202 is slidably provided on one side of the horizontal plate 201 away from the mounting plate 104, and the sliding sleeve 202 is connected to the horizontal plate 201 by bolts, so that the sliding sleeve 202 can be easily disassembled, and then the warning plate 204 can be replaced, and the warning plate 204 suitable for different warning words is provided with a slide groove 203 at the lower end of the horizontal plate 201, and the warning plate 204 is slidably connected inside the slide groove 203, and the warning plate 204 provides a large area of ​​space to display prompt information, which is convenient for directly reminding nearby personnel, and warning light strips 205 are fixedly installed on the surfaces of the warning plate 204 and the horizontal plate 201, so that in a relatively dim situation, nearby personnel can also observe the device and thus stay away from the position of the aircraft air intake;

[0030] Among them Figure 2 and Figure 5 , Figure 6 As shown, the support mechanism 300 includes a plurality of grooves 301 arranged on the surface of the base 101, and the grooves 301 are rotatably connected to the support plates 302. When the roller 105 moves to the area near the aircraft air inlet, the user manually drives the slide plate 304 to move upward, so that the support plate 302 can smoothly contact the ground, thereby increasing the contact area between the device and the ground. The end of the support plate 302 away from the groove 301 is fixedly connected to the bottom plate to improve safety and stability. L-shaped grooves 303 are symmetrically arranged on both sides of the support plate 302, which is convenient for the card on one side of the slide plate 304 to be clamped. The block is inserted into the L-shaped groove 303, and the outer side of the support rod 103 is slidably connected with a slide plate 304. A plurality of openings 305 are arranged on the surface of the slide plate 304. The openings 305 correspond to the position and number of the support plate 302. A block adapted to the L-shaped groove 303 is arranged on the inner wall of the opening 305. When the support plate 302 needs to be stored, the user moves the slide plate 304 upward, and then aligns the plurality of openings 305 with the L-shaped groove 303, and then drives the slide plate 304 to move downward, thereby fixing the support plate 302, making it convenient for the user to move the device;

[0031] Among them Figure 2 and Figure 4As shown, the winding mechanism 400 includes a storage box 401, and a winding rod 402 is rotatably arranged inside the storage box 401. A traction structure for limiting the warning tape 403 is arranged on one side of the winding rod 402, so that when the winding rod 402 rotates, the warning tapes 403 inside the storage box 401 are still in a tightly fitted state. One end of the rotating shaft of the winding rod 402 extends to the outside of the storage box 401 and is fixedly connected to the output end of the motor. The motor is fixedly arranged on the top of the mounting plate 104. A traction hole is opened on the outer surface of the storage box 401. The size of the warning tape 403 matches the size of the traction hole. The hook 404 The thickness is greater than the size of the towing hole, so that the warning tape 403 can freely enter and exit the towing hole, and the hook 404 can prevent the warning tape 403 from being completely retracted. The interior of the towing hole is slidably connected with the warning tape 403. The warning tape 403 is an elastic tape with text warning effects commonly seen on the market, which can enclose or block the area outside the aircraft air inlet to prevent people from approaching the aircraft air inlet, and the warning tape 403 is wound around the outside of the winding rod 402. The end of the warning tape 403 is fixedly connected with a hook 404. Through the hook 404, one end of the warning tape 403 can be fixed to prevent the warning tape 403 from retracting.

[0032] Among them Figure 1 and Figure 2 As shown, the lower end of the base 101 is symmetrically provided with rollers 105, which are self-locking universal wheels and play the role of supporting the warning device for personnel approaching the aircraft air intake, so as to facilitate movement;

[0033] Among them Figure 2 As shown, a handle 106 is fixedly provided on one side of the support rod 103, so that the user can manually pull the handle 106 and then move the device to other positions with the cooperation of the rollers 105.

[0034] Example 2

[0035] The difference from Example 1 is that Figure 2 As shown, a guide rod 306 is fixedly connected to the upper surface of the base 101, and the slide plate 304 is slidably connected to the guide rod 306. The guide rod 306 guides the slide plate 304 to prevent the opening 305 on the surface of the slide plate 304 from being unable to quickly contact the support plate 302, which affects the practical effect of the device;

[0036] Among them Figure 4 As shown, a buckle 405 matched with the hook 404 is fixedly provided on one side of the storage box 401. The user can stretch the warning tape 403 to a certain length and fix the length of the warning tape 403 through the buckle 405 of the adjacent warning device.

[0037] When in use, the user moves the device to the corresponding position through the cooperation between the roller 105 and the handle 106. When the support mechanism 300 needs to be used, the user manually drives the slide plate 304 to move upward. Due to the limiting effect of the guide rod 306, the L-shaped groove 303 on the surface of the support plate 302 can be separated from the opening 305, and then can be smoothly in contact with the ground to achieve a supporting effect. When the warning mechanism 200 needs to be used, a suitable warning plate 204 is selected, and with the cooperation of the slide groove 203 and the sleeve 202, the warning plate 204 is fixedly installed inside the horizontal plate 201 to achieve a warning effect.

[0038] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
