Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-3The embodiment discloses an emergency radiation measuring device for an accident site, which comprises a shell 6 with an open upper end, the outer circumferential side of the shell 6 and one end of a supporting rod 3 are rotationally connected through a hinge seat or a hinge, the other end of the supporting rod 3 is provided with a handle 2 arranged perpendicularly, the handle 2 is provided with a threaded hole, a screw rod 8 is arranged in the threaded hole in a threaded manner, the outer circumferential side of the shell 6 is connected with one end of a connecting rope 4, and the other end of the connecting rope 4 is rotationally connected with one end of the screw rod 8 through a rotating pin or a bearing.

[0021] A communication hole is formed in the bottom of the inner cavity of the shell 6, an extension pipe 14 extends inwardly from the inner side of the communication hole, a clockwork escapement 11 is arranged in the bottom of the inner cavity of the shell 6, a helical blade 12 is arranged on the output shaft of the clockwork escapement 11, one end of the helical blade 12 extends into the extension pipe 14, the outer side of the helical blade 12 is in sliding contact with the inner wall of the extension pipe 14, and the clockwork escapement 11 drives the helical blade 12 to rotate.

[0022] A radiation measuring buzzer 7 is arranged on the outer circumferential side of the shell 6.

[0023] Further, the supporting rod 3 is a multi-section telescopic rod, and one section of the supporting rod 3 provided with the handle 2 is provided with a plurality of restraint belts 1, and the device occupies a small space and is convenient to store after the telescopic rod is contracted.

[0024] Further, the supporting rod 3 and the connecting rope 4 are located on the same vertical plane, and the connecting rope 4 is located above the supporting rod 3.

[0025] Preferably, the shell 6 is made of transparent plastic material or transparent glass material, and lime powder, powder paint and other powder materials are arranged in the shell 6, so that the remaining amount of the powder materials in the shell 6 can be observed.

[0026] The radiation measuring buzzer 7 is a handheld radiation measuring device commonly used in the prior art, which emits a buzzing sound when detecting radiation, and the stronger the radiation intensity is, the louder the buzzing sound is.

[0027] The clockwork escapement 11 is a common power component in clocks and toys in the prior art, the input shaft of the clockwork escapement 11 can be rotated to wind the clockwork, and the output shaft of the clockwork escapement 11 can rotate at a certain speed.
