[0021] Reference Figures 1 to 3 .
[0022] The medical radiation protection alarm device proposed by the utility model is further explained.
[0023] A medical radiation protection alarm device, comprising:
[0024] A fixed plate 1 is rotatably connected to a rotating plate 2, and a radiation detector 3 and an alarm 4 are rotatably connected to the rotating plate 2.
[0025] The cleaning mechanism 5 includes a sliding plate 6, which is slidably connected to the alarm 4, and at least two brushes 7 are fixedly connected to the side wall of the sliding plate 6. The end of the brush 7 is located in the sound hole of the alarm 4. The brush 7 includes a connecting rod, and a layer of bristles is spirally distributed on the connecting rod, which is convenient for cleaning the dust in the sound hole of the alarm 4 to prevent the sound hole on the alarm 4 from being blocked.
[0026] A driving motor 8 is fixedly connected to the fixed plate 1 , and an output shaft of the driving motor 8 passes through the fixed plate 1 and is fixedly connected to the rotating plate 2 .
[0027] The rotating plate 2 is T-shaped, and the end of the rotating plate 2 is rotatably connected to the rotating shaft 9. The radiation detector 3 and the alarm 4 are respectively fixedly connected to the lower ends of the rotating shaft 9, and the radiation detector 3 and the alarm 4 are electrically connected. The radiation detector 3 is distributed at both ends of the rotating plate 2, and the alarm 4 is distributed at one end of the rotating plate 2, which is convenient for detecting the radiation conditions at different positions.
[0028] A gear 10 is fixedly connected to the rotating shaft 9 , and an inner gear ring 11 is fixedly connected to the lower surface of the fixed plate 1 . The inner gear ring 11 meshes with the gear 10 .
[0029] A sliding rod 12 is fixedly connected to the sliding plate 6, and a sliding groove 13 is opened on the side wall of the alarm 4. The end of the sliding rod 12 is slidably connected in the sliding groove 13. The sliding rod 12 is L-shaped, and the lower end of the vertical section of the sliding rod 12 is slidably connected in the sliding groove 13, which is convenient for the sliding plate 6 to move back and forth, thereby driving the movement of the position of the brush 7, so that the brush 7 can clean the dust in the holes on the alarm 4.
[0030] A spring 14 is fixedly connected to the upper surface of the sliding plate 6 , the upper end of the spring 14 is fixedly connected to the alarm 4 , and the sliding plate 6 is in contact with the inner gear ring 11 .
[0031] Working principle: the fixing plate 1 is fixed at the specified position by screws and other existing technical means. When it is necessary to detect the radiation situation in the space, the driving motor 8 is started. The output shaft of the driving motor 8 drives the rotating plate 2 to rotate, driving the radiation detector 3 and the alarm 4 to rotate. The radiation detector 3 rotates in a circular manner, so that it is convenient for the radiation detector 3 to detect the radiation situation in different areas along the circular track, thereby improving the detection effect of the radiation detector 3. During the rotation of the rotating plate 2, the gear 10 is driven to rotate in a circular manner. Due to the meshing of the gear 10 with the inner gear ring 11, the driving gear 10 rotates, driving the rotating shaft 9, the alarm 4 and the sliding plate 6 to rotate. When the sliding plate 6 rotates, the rotating plate 2 rotates in a circular manner. When the movable plate 6 contacts the inner gear ring 11, the inner gear ring 11 limits the sliding plate 6 and pushes the sliding plate 6 toward the alarm 4 during its rotation, driving the brush 7 to move toward the alarm 4, so that the brush 7 is inserted into the sound hole on the alarm 4. When the sliding plate 6 is free from the limit of the inner gear ring 11, the spring 14 pushes the sliding plate 6 away from the alarm 4 through the elastic force of the spring 14, driving the brush 7 to move out of the sound hole on the alarm 4. When the brush 7 moves out of the sound hole on the alarm 4, the dust in the sound hole on the alarm 4 is brought out of the hole, thereby preventing the sound hole of the alarm 4 from being blocked and facilitating the normal use of the alarm 4.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
