Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a sediment sampling device for river channel management in water conservancy projects. Background Art

[0002] Scour and siltation often occur in natural rivers, which are prone to water disasters and hinder the development of water conservancy. In order to meet the requirements of eliminating hazards and promoting benefits, appropriate measures must be taken to regulate the river, including projects such as guidance, dredging and bank protection. When implementing related projects, it is necessary to sample and inspect the sediment in the relevant river areas.

[0003] After searching the announcement number: CN216846969U, a sediment sampling device for river channel management in water conservancy projects is found, including a motor, a base is arranged at the bottom of the motor, a lifting device is arranged on one side of the top of the base, extension plates are installed on both sides of the lifting device, and a collecting device is installed on one side of the bottom of one of the extension plates; using the lifting device, the motor is connected to an external power supply and the motor starts to work. This application solves the problems of time-consuming, labor-intensive and extremely low efficiency.

[0004] However, after the drill bit in the application drills into the mud, the sampling plate also penetrates into the mud. When the movable plate moves to generate thrust, the sampling plate is sometimes unable to be opened because it is buried too deep in the mud, and the mud cannot be collected.

[0005] Therefore, we designed a sediment sampling device for river management in water conservancy projects. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a sediment sampling device for river channel management in a water conservancy project, which solves the problem that a sampling plate sometimes cannot be opened and sediment cannot be collected.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A sediment sampling device for river channel management of a water conservancy project comprises a base, a transmission assembly is fixedly connected inside the base, a lifting assembly is fixedly connected to the right side of the top of the base, and a sand sampling assembly is fixedly connected to the bottom of the lifting assembly;

[0009] The sand taking assembly includes a drill rod fixedly connected to the bottom of the lifting assembly, a plurality of sand sliding grooves are provided on the surface of the drill rod, a pressure plate is slidably connected to the surface of the drill rod, two groups of electric push rods are fixedly connected to the top of the pressure plate, and the tops of the two groups of electric push rods are fixedly connected to the bottom of the lifting assembly, a drill bit is fixedly connected to the bottom of the drill rod, and a plurality of water leakage holes are provided on the surface of the drill bit.

[0016] 1. Through the sand-collecting assembly, when the connecting plate drives the sand-collecting assembly to descend into the river channel, the drill bit goes deep into the mud and sand, and then the connecting plate drives the entire sand-collecting assembly to rise. When the drill bit rises, the mud and sand inside the drill bit will be brought up, and at the same time, two sets of electric push rods are started to drive the pressure plate to descend on the surface of the drill rod, so that the pressure plate is pressed into the drill bit, so that when the drill bit rises, the mud and sand inside the drill bit will not flow out with the water flow.
