Description

Technical Field

[0001] The utility model relates to a surveying device, in particular to a surveying device used for water conservancy and hydropower. Background Art

[0002] During construction surveys, soil sampling is required. A Chinese patent application numbered CN201922015321.X provides a solution for surveying equipment for water conservancy and hydropower construction. The solution involves using a rotary motor to drive a drill rod to rotate, and a worker holding a handle rotates the handle to rotate the screw, thereby gradually lowering a lifting plate. The bottom end of the drill rod passes through the inner ring of the annular sampling plate and drills into the soil layer. The drilled soil accumulates on the upper surface of the annular sampling plate. When sampling, the operator needs to hold the handle and rotate it, and the screw rotates to drive the lifting plate down. This method is laborious and has low stability. In addition, all the drilled soil accumulates on the upper surface of the annular sampling plate, making it impossible to distinguish soil at different depths.

[0003] Chinese patent application number CN202322981278.9 provides a solution for soil sampling equipment at different depths. The solution is to splice two sampling tubes into a tubular structure, insert the soil sampling mechanism shallowly at the upper end of the soil layer to be sampled, lift the main unit, and insert the impact adapter into the socket inside the lower end of the connecting column. Under the action of the main unit, the soil sampling mechanism will be driven into the soil layer. After the sampling is completed, the two sampling tubes are separated to obtain a columnar soil layer sample between the two sampling tubes. This solution effectively solves the problem of all the samples taken being piled up on the ground. However, on the one hand, when sampling, the soil sampling mechanism is shallowly inserted at the upper end of the soil layer to be sampled, and then extended downward by the main unit to sample. Since there is no guide limit function when the soil sampling mechanism is extended downward for sampling, it is easy to deviate when extending downward for sampling, resulting in unsuccessful sampling and the need for secondary sampling. On the other hand, the strong jitter leads to high labor intensity for the operator. On the other hand, it is not easy to transport.

[0004] Therefore, those skilled in the art are committed to providing a survey device for water conservancy and hydropower that can effectively solve the above technical problems. Utility Model Content

The two sleeves 10 are held by hand and used in conjunction with the first spring 11 and the second spring 12 to reduce vibration. At the same time, the main unit 6 slides with the support seat 5 through the guide rail 36, effectively preventing deviation during sampling, reducing the sampling intensity of the operator and improving the stability of the overall structure during sampling; after the sampling is completed, the sampling unit 18 is pulled out, and the first semi-cylindrical tube 19 and the second semi-cylindrical tube 20 are separated to obtain the soil sample between the first semi-cylindrical tube 19 and the second semi-cylindrical tube 20.
