The whole device is operated through wireless control mechanism, so that the user can control the lifting of sampler and the movement of float 1 and other actions away from the sampling point, thereby safely and efficiently completing the water body sampling work.

[0019] In order to facilitate the sampler to be smoothly guided into the installation cavity 3 by the lifting mechanism, in the embodiment, as a preferred technical solution of the present application, the diameter of the top end of the cylinder 4 gradually increases from top to bottom.

[0020] In order to facilitate recycling and put down the sampler while facilitating the control of the sampling depth according to the length of the traction rope 13, in the embodiment, as a preferred technical scheme of the utility model, the lifting mechanism comprises a take-up reel 12, the take-up reel 12 is installed at the top end of the float 1, the take-up reel 12 is wound with the traction rope 13, one end of the traction rope 13 is fixedly connected to the top end of the pull rod 8, and one end of the take-up reel 12 is installed with a servo motor 14.

[0022] In order to prevent fixed impurities from entering the water sample, in the embodiment, as a preferred technical scheme of the utility model, the filter screen 15 is installed inside the water inlet 6 of the cylinder body 4.

[0023] In order to facilitate the opening of the cylinder cover 5 to clean the filter screen 15, in the embodiment, as a preferred technical scheme of the utility model, the cylinder body 4 and the cylinder cover 5 are connected through threads.

[0024] Based on the technical scheme of the utility model, the operation process is as follows: firstly, the float 1 is put into the sewage water body. The controller then sends a control electric signal to the wireless signal transmitting module, the wireless signal transmitting module converts the electric signal into a wireless signal and transmits it to the wireless signal receiving module. The wireless signal receiving module restores the wireless signal into an electric signal, and then controls the operation of the electric propeller 2 to drive the float 1 to move in the sewage. After reaching the predetermined water area, the controller instructs the electric propeller 2 to stop again through the wireless signal transmitting and receiving modules, so that the float 1 is stabilized at the target position. At the same time, the controller again rotates the take-up reel 12 by means of the wireless signal output module and the wireless signal receiving module servo motor 14, accurately releases the length of the traction rope 13, and makes the sampler drop to the specified depth due to the weight. At this time, since the length of the connecting rope 11 is limited and one end is fixed on the float 1, the one end of the compression rod 10 rises under the action of buoyancy, causing the disengagement of the clamping part of the rod body of the pull rod 8, the pull rod 8 loses the compression force, the elastic rope 9 is contracted, the piston 7 is pulled up, and the water sample is sucked into the cylinder body 4 from the water inlet 6 by using the air pressure. The filter screen 15 filters out solid impurities at the same time. After the water sample collection is completed, the controller reverses the servo motor 14 by means of the wireless signal output module and the wireless signal receiving module, and tightens the traction rope 13 to recover the sampler into the installation cavity 3. Since the top end of the sampler cylinder body 4 has a smaller diameter, it can be smoothly guided into the installation cavity 3 of the float 1. Finally, the float 1 returns to the shore through the electric propeller 2, and the whole water sample collection process is completed.
