[0014] To achieve the above purpose, the utility model adopts the following technical scheme:

[0015] The utility model provides a kind of standby positioning equipment for marine rescue, including transponder and base, the top center position of the base is fixedly provided with recessed cylinder, the recessed cylinder is concave, the inner wall of the recessed cylinder is slidably connected with lifting column, the side of the lifting column is fixedly provided with connecting column, the side of the connecting column is fixedly provided with frame body;

[0016] Clamping mechanism is arranged on frame body for clamping and fixing transponder;

[0017] Adjusting mechanism is arranged in recessed cylinder for freely adjusting the height of transponder;

[0018] Illumination mechanism is arranged on one side of recessed cylinder for lighting at night.

[0019] In a possible design, the clamping mechanism includes a clamping plate, a first threaded rod, and a handle for facilitating rotation of the first threaded rod. The clamping plate is slidably connected to the inner walls of the frame body on both sides. A first threaded hole is formed in the frame body. The first threaded rod is threadedly connected to the first threaded hole of the frame body. One end of the first threaded rod is rotatably connected to one side of the clamping plate. The handle is fixedly connected to the other end of the first threaded rod. The clamping plate is arc-shaped.

[0020] In a possible design, the adjusting mechanism includes a rotating rod, a second threaded rod, and two bevel gears. A bearing is embedded in one side of the recessed cylinder. The outer side of the rotating rod is fixedly connected to the inner ring inner wall of the bearing. The bottom end of the second threaded rod is rotatably connected to the bottom inner wall of the recessed cylinder. Two bevel gears are fixedly sleeved on the rotating rod and the second threaded rod, respectively. The two bevel gears are meshed. A second threaded hole is formed in the lifting column. The second threaded rod is threadedly connected to the second threaded hole of the lifting column. One end of the rotating rod is fixedly provided with a hand wheel for facilitating rotation of the rotating rod.

[0021] In a possible design, the illumination mechanism includes a fixed plate, a universal sleeve, a universal ball, and a lighting lamp. One side of the fixed plate is fixedly connected to one side of the recessed cylinder. The bottom of the universal sleeve is fixedly connected to one side of the top of the fixed plate. The outer side of the universal ball is slidably connected to the inner wall of the universal sleeve. The top of the universal ball is fixedly provided with a cylinder. The bottom of the lighting lamp is fixedly connected to the top end of the cylinder. A third threaded rod for limiting the universal ball is threadedly connected to the universal sleeve. One end of the third threaded rod is fixedly provided with a knob for facilitating rotation of the third threaded rod.

[0022] In a possible design, the clamping plate and the frame body are fixedly provided with rubber pads on the side close to each other for improving the clamping effect of the transponder.

[0023] In a possible design, the concave cylinder and the lifting column are both elliptical in shape.

[0024] In a possible design, the two side inner walls of the frame body are both provided with sliding grooves for reducing friction caused by movement of the clamping plate, and the clamping plate is provided with sliding blocks on both sides, which are in sliding connection with the inner walls of the sliding grooves.

When the height of the transponder needs to be freely adjusted, the hand wheel is held and rotated clockwise or counterclockwise. Rotation of the rotating rod transmits power to the second threaded rod through the two meshing bevel gears, so that the second threaded rod is rotated. The rotation of the second threaded rod interacts with the second threaded hole on the lifting column to drive the lifting column to slide up and down in the concave cylinder. Movement of the lifting column drives the connecting column and the clamped transponder to move, so that the height of the transponder can be freely adjusted. Since the concave cylinder and the lifting column are elliptical in shape, the lifting column will not rotate when it is lifted. In a maritime rescue operation, when positioning is needed, the transponder is started to emit a signal for quick positioning of search and rescue personnel (through detection of a search and rescue ship or a helicopter navigation radar probe pulse, the signal emitted by the SART can be displayed on the navigation radar screen of the search and rescue ship or the helicopter to show the exact position of the SART). When the transponder is used at night, the illuminating lamp can be turned on to generate light source, so that personnel on the helicopter can observe the position of the ship. During the illumination process, the cylindrical body at the bottom of the illuminating lamp can be shaken by hand to drive the universal ball to move in the universal sleeve, so that the illuminating lamp can be rotated at multiple angles to facilitate the illuminating lamp to search for the helicopter. Rotation of the knob drives the third threaded rod to rotate, so that the third threaded rod is tightly attached to the universal ball to limit the universal ball and prevent it from rotating.

[0027] The application has the following beneficial effects:
