Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project safety monitoring sampling device. Background Art

[0002] Safety monitoring and sampling of water conservancy projects is an important part of ensuring the safe operation of reservoirs, rivers and other water conservancy facilities. Especially in flood seasons, droughts or periods when water quality changes significantly, regular collection of water samples and testing can help us keep abreast of changes in water bodies and prevent safety accidents.

[0003] Most sampling devices currently available on the market rely on manual operation, requiring the operator to place the sampler into the water, extract the water sample, and pour it into a sample tube. This cumbersome process also presents potential safety risks due to hand contact with the sampling bowl. Due to the complex environments of water conservancy projects such as reservoirs, especially in slippery or dangerous areas, manual operation can easily cause the sampling bowl to slip or the sample to spill, resulting in sample contamination and even personal injury.

[0004] Therefore, a water conservancy project safety monitoring sampling device is needed to solve the above technical defects. Utility Model Content

[0010] Preferably, a reserved groove is provided above the threaded rod and arranged along the length direction of the threaded rod, and the top end of the threaded block is embedded in the reserved groove and moves.

[0011] Preferably, an axle seat is mounted on the top of the fixing frame, a hoisting motor is fixedly connected to the left side of the fixing frame, a lifting rope is wound around the axle seat, the hoisting motor drives the lifting rope to rotate through the transmission assembly, and the bottom end of the lifting rope is hoisted to both sides of the top of the sampling bowl.

[0012] Preferably, two groups of grippers are provided, and the inner sides of the grippers match the shape of the sampling bowl.

After clamping, the clamping hand is driven to flip by the steering motor, thereby driving the sampling bowl filled with the sample to flip stably, and the sample is poured from the sampling port into the transparent sample tube, realizing the function of automatically pouring the sample without holding the sampling bowl, avoiding the potential safety risk of contact between the hand and the sampling bowl, and avoiding the splashing of liquid generated when the sample is poured, especially in a wet and slippery environment such as a reservoir, thereby improving the safety of the operator;

When the sampling bowl rises, it can return to its original position stably, avoiding the swing or deviation of the sampling bowl, avoiding the deviation of the moving trajectory, and improving the accuracy of sampling;

[0017] (3) By providing a fixed frame and a cylinder, the device reduces human intervention through mechanized operation, which not only saves time but also reduces the error rate during the sampling process.
