[0030] Example 1

[0031] Reference Figures 1 to 9 The present embodiment provides a non-contact train approach alarm device, including a support mechanism 100, the support mechanism 100 includes a vertical frame rod 101 and a cross bar 102, the cross bar 102 is installed on the top of the vertical frame rod 101, and scanning radars 102a are arranged at both ends of the outer wall of the cross bar 102, and a photovoltaic panel 103 and a control box 104 are installed on the outer wall of the vertical frame rod 101; a sweeping mechanism 200, the sweeping mechanism 200 includes a sweeping member 201 and a transmission member 202, wherein the sweeping member 201 is provided with a scanning radar 102a; and a driving mechanism 200 includes a driving member 201 and a transmission member 202. 01 includes a rotating roller 201a, a sweeping rod 201b and an external rod 201c. The rotating roller 201a is movably installed on the outer wall of the vertical frame rod 101, and the sweeping rod 201b is fixedly connected to the outer wall of the rotating roller 201a. The transmission member 202 includes a transmission roller 202a and a pull rod 202b. The transmission roller 202a is movably connected to the inside of the vertical frame rod 101, and the pull rod 202b is fixedly connected to the transmission roller 202a. The transmission roller 202a cooperates with the rotating roller 201a.

[0032] The rotating roller 201a is annular. A bearing 101a is fixedly installed on the outer wall of the vertical support rod 101. The rotating roller 201a is connected to the bearing 101a, and the rotating roller 201a is rotatably connected to the vertical support rod 101 through the bearing 101a; the rotation of the rotating roller 201a drives the rotation of the sweeping rod 201b.

[0033] The shape of the sweeping rod 201b is "匚". Limiting blocks 201b-1 are arranged at both ends of the top of the sweeping rod 201b. The external connecting rod 201c is sleeved between the two groups of limiting blocks 201b-1 of the sweeping rod 201b; the function of the sweeping rod 201b is to drive the external connecting rod 201c to rotate synchronously to clean the sundries remaining on the top of the scanning radar 102a.

[0034] A transmission tooth 201c-1 is arranged in the middle of the outer wall of the external connecting rod 201c, and a transmission tooth 201c-1 is also arranged at the top end of the vertical support rod 101. The transmission tooth 201c-1 at the top of the external connecting rod 201c meshes with the transmission tooth 201c-1 at the top end of the vertical support rod 101. The specific function of this structure is that when the external connecting rod 201c rotates around the axis of the vertical support rod 101, at the same time, due to the meshing of the two groups of transmission teeth 201c-1, the external connecting rod 201c will also rotate around its own axis, so as to clean the sundries more effectively.

[0035] A sliding groove 101b is opened on the outer wall of the vertical support rod 101 near the bearing 101a. A sliding convex block 201a-1 is installed on the inner wall of the rotating roller 201a. A spiral groove 202a-1 is opened on the outer wall of the transmission part 202. The sliding convex block 201a-1 penetrates through the sliding groove 101b and fits with the inner wall of the spiral groove 202a-1 of the transmission roller 202a; when the transmission roller 202a moves up and down inside the vertical support rod 101, due to the sliding convex block 201a-1 arranged on the inner wall of the rotating roller 201a fitting and slidingly connecting with the inner wall of the spiral groove 202a-1, the rotating roller 201a rotates.

[0036] A pulling groove 101c is opened at the bottom of the outer wall of the vertical support rod 101. The shape of the pull rod 202b is "L". One end of the pull rod 202b penetrates through the pulling groove 101c and the other end is fixedly connected to the bottom of the transmission roller 202a; by pulling the pull rod 202b, the transmission roller 202a moves up and down inside the vertical support rod 101.

[0037] A spring is fixedly connected to the bottom of the transmission roller 202a. The other end of the spring at the bottom of the transmission roller 202a is connected to the inner wall of the vertical support rod 101. When the transmission roller 202a moves, the transmission roller 202a is reset by the spring.

[0038] The scanning radar 102a, the photovoltaic panel 103 and the control box 104 are all electrically connected to each other. A main control unit is arranged inside the control box 104, and the main control unit is connected to the scanning radar 102a through 4G signal transmission.

[0039] In some embodiments, the outer wall of the external rod 201c is provided with a brush or hook for cleaning, which is used to clean certain sticky debris.

[0040] Working principle: When there are debris on the top of the stand rod 101 and it blocks the scanning radar 102a, thus affecting the anti-intrusion system, pull the pull rod 202b, and drive the transmission roller 202a to slide up and down inside the stand rod 101 through the pull rod 202b. When the pull rod 202b slides up and down inside the stand rod 101, the sliding protrusion 201a-1 provided on the inner wall of the rotating roller 201a is attached to and slidably connected with the inner wall of the spiral groove 202a-1, so that the rotating roller 201a is in the bearing of the stand rod 101. The scanning radar 102a is rotated at 101a, and the sweeping rod 201b and the external rod 201c are driven to rotate synchronously through the rotation of the rotating roller 201a. The debris trapped on the top of the scanning radar 102a is cleaned up through the rotation of the sweeping rod 201b. During the cleaning process, due to the meshing of the two sets of transmission teeth 201c-1, when the external rod 201c follows the rotation of the sweeping rod 201b, it will also rotate with the axis of the external rod 201c as the center, thereby more effectively cleaning the debris trapped on the top of the scanning radar 102.

[0041] Among them, the specific anti-intrusion system has been disclosed by the "A Radar and Vision Fusion Intelligent Anti-Intrusion Warning System" with the publication number "CN219237054U", so it will not be repeated here.
