[0028] In this example, the right end of the first connecting rod 202 passes through the left side of the box body 201 and extends to the inside of the box body 201. The connecting column 205 is rotatably connected to the back wall of the inner cavity of the box body 201 through a bearing. The front and rear side walls of the inner cavity of the box body 201 are provided with positioning grooves. The front and rear sides of the first gear plate 207 are fixed with two positioning blocks horizontally slidably connected to the positioning grooves. By starting the output shaft at the right end of the dual-axis motor 3, the first connecting rod 202 drives the first bevel gear 203 and the second bevel gear 204 to rotate, and drives the connecting column 205 and the first gear 206 rotates, so that the first gear 206 drives the first tooth plate 207 to move rightward, and the delivery cylinder 5 is lifted up by the hinged plate 208 to achieve the purpose of adjusting the delivery angle of the delivery cylinder 5.

[0031] In this example, the steel rope 211 is fixed on the outside of the lifting ring 404, and the elastic member 405 includes a second spring and a damper. The second spring is sleeved on the outside of the damper. The buoy to be released is placed inside the releasing tube 5 and is located on the right side of the push plate 210. By starting the output shaft at the left end of the dual-axis motor 3, the half-tooth gear 402 starts to rotate and drives the second tooth plate 403 to move downward and squeeze the second spring and the damper. A groove is provided on the upper surface of the base 1. The second spring and the damper are fixed on the inner bottom wall of the groove. When the second tooth plate 403 starts to move downward and squeezes the second spring and the damper, the steel rope 211 pulls the push plate 210 to move left.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The working principle of the above embodiment is:

[0036] (1) When the portable buoy launching device for hydrological survey is needed, the portable buoy launching device for hydrological survey is moved to the hydrological survey area where the buoy needs to be launched through the universal wheel 6, and then the launched buoy is placed inside the launching tube 5 and located on the right side of the push plate 210. By starting the output shaft at the left end of the dual-axis motor 3, the half-tooth gear 402 starts to rotate and drives the second tooth plate 403 to start moving downward and squeeze the second spring and the damper, and the steel rope 211 pulls the push plate 210 to move left. When the half-tooth gear 402 is no longer in contact with the second tooth plate 403, the second spring and the first spring 209 begin to reset and quickly move the push plate 210 to the right to launch the buoy.

[0037] (2) When the delivery angle needs to be adjusted, the output shaft at the right end of the dual-axis motor 3 is started, so that the first connecting rod 202 drives the first bevel gear 203 and the second bevel gear 204 to rotate, and drives the connecting column 205 and the first gear 206 to rotate, so that the first gear 206 drives the first gear plate 207 to move to the right, and the delivery cylinder 5 is lifted up by the hinge plate 208 to achieve the purpose of adjusting the delivery angle of the delivery cylinder 5. After the adjustment is completed, the lower surface of the delivery cylinder 5 can be supported by the electric telescopic column fixed on the upper surface of the box body 201 and close to its right end, thereby improving the stability of the delivery cylinder 5.
