[0003] However, after sampling the water quality sample, the sample is poured and placed in the corresponding storage tank, and then transported to the indoor sample detection process. In this process, the storage tank needs to be transported and moved. In order to avoid the overflow of water quality sample from the tank, the subsequent detection of the sample is affected, and the storage tank top is provided with a corresponding sealing cover. The sealing cover can be fixed by the lock outside the sealing cover, so as to realize the fixation of the sealing cover. Such fixation method cannot be locked and fixed from the inside of the cover, so as to cause the cover to shake and collide during the whole transportation, and the sealing storage of the sample water in the tank is affected. Therefore, we propose a hydrology and water conservancy water quality sampling device with sealing storage mechanism. UTILITY MODEL CONTENT

[0017] 1. The technical solution of the present application is a hydrological and water conservancy water quality sampling device with a sealed storage mechanism. Four groups of rotating screws are arranged inside the cross transmission frame located at the top of the sealing cover frame. Combined with the meshing transmission action of the follower bevel gear and the transmission bevel gear located on the side of the rotating screw, when the servo motor drives the transmission bevel gear to rotate, it can drive the rotating screws located on the four sides of the cross transmission frame to rotate synchronously. Then, combined with the rotational transmission action of the rotating screw on the transmission sleeve, the four groups of transmission sleeves can be driven synchronously to move horizontally toward or relative to each other inside the cross transmission frame, thereby driving the bonding plate located on the inside of the sealing cover frame to move synchronously toward or relative to each other, so that the outer side of the bonding plate can be fully bonded to the inner wall of the storage tank, and provide corresponding limiting force to the sealing cover frame from the inside of the storage tank to prevent the storage tank from shaking and colliding arbitrarily during transportation and movement, causing the sealing cover frame to detach from its surface and affect the storage quality of the water sample.

A sealing limit column is arranged on the side of the bonding plate, and a plug-in groove that is adapted to the size of the sealing limit column is opened on the side of the sealing cover frame and the storage tank. When the bonding plate is bonded to the inner wall of the storage tank and provides an installation limit force to the sealing cover frame, the sealing limit column can further provide the sealing cover frame with a corresponding supporting force, thereby further improving the installation stability of the sealing cover frame.
