The specific implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figures 1 to 3, the mud sand sampling system provided by the embodiment of the utility model includes: a pool, a sampling port 2, a water pump 4 and a backflow stirring device, the sampling port 2 is arranged on the wall of the pool, and the backflow The stirring device is arranged at the bottom of the pool, the water pump 4 communicates with the reflux stirring device and the sampling port 2 respectively, and the reflux stirring device includes a pipeline 6 provided with a plurality of water spray nozzles 7 . The water pump 4 communicates with the reflux stirring device and the sampling port 2 respectively through a tee. The pipe 6 is 500-1000mm long and 50-100mm in diameter.

In the mud sand sampling system provided by the utility model, the pipeline with multiple water spray nozzles in the reflux stirring device is used to stir the water in the pool, and only simple assembly is required for large-volume sampling. Multiple water spray pipes are provided The pipe of the mouth, the stirring effect is good and the cost is low. The utility model has the advantages of long service life, convenient use and simple structure.

In this embodiment, the water spray nozzle 7 is cylindrical and communicated with the pipeline 6 by means of welding or bonding. In the horizontal direction, it is opposite to the movement direction of the water flow, and sprays water against the current flow. In the vertical direction, the nozzle near the incoming flow direction sprays water downward at 45°, and away from the incoming flow direction, the nozzle near the submersible sewage pump sprays water upward at 45°; The first nozzle 8, and the second nozzle 9 corresponding to the top of the pool. Both the first nozzle 8 and the second nozzle 9 are arranged at an angle of 40-50° to the pipeline 6 . The first nozzles 8 and the second nozzles 9 are alternately arranged at intervals of 10-30mm. The length of the first nozzle 8 and the second nozzle 9 is 15-60mm, and the inner diameter is 5-20mm. Most of the water flow turns back to the reflux stirring device, flows out from the nozzle, and forms a jet under the high pressure of the water pump 4, thereby forming agitation for the water body. The downward high-speed water flow from the first nozzle 8 collides with and scours the bottom of the pool, forcing the water flow to turn back, enlarging the turbulent area, and pushing the water body to flow upward, thereby destroying the layering of mud and sand in the water body, causing the mud and sand to turn up and resuspend. After the second nozzle 9 is re-suspended, the mud and sand need to be sprayed and stirred upwards, which can prevent it from redepositing layers, keep its suspended state, and mix more evenly.

The mud sand sampling system provided by the utility model includes a flow control valve 5 arranged on the pipeline between the water pump 4 and the sampling port 2 . The flow control valve 5 in this embodiment adopts a ball valve.

A sediment sampling method using a sediment sampling system, including the above-mentioned sediment sampling system, wherein:

S1. The pipeline 6 provided with a plurality of water spray nozzles 7 is arranged perpendicular to the flow direction of the water flow; in this embodiment, the flow direction of the water flow is the A direction, and the B direction is the stirring direction of the reflux stirring device.

S2, the water spray nozzle 7 sprays water in the opposite direction of the water flow, and stirs the mud and sand evenly;

S3. The water pump 4 pumps the uniformly stirred water to the water intake 2 .

During the use of the mud and sand sampling system of the utility model: most of the water flows back to the reflux stirring device, flows out from the nozzle, and forms a jet under the high pressure of the water pump 4, thereby forming agitation for the water body. The downward high-speed water flow from the first nozzle 8 collides with and scours the bottom of the pool, forcing the water flow to turn back, enlarging the turbulent area, and pushing the water body to flow upward, thereby destroying the layering of mud and sand in the water body, causing the mud and sand to turn up and resuspend. After the second nozzle 9 is re-suspended, the mud and sand need to be sprayed and stirred upwards, which can prevent it from redepositing layers, keep its suspended state, and mix more evenly. Another small part of the water flows out from the sampling port 2 and enters the sampler. According to the size of the sampler, the flow is controlled by a ball valve. In this way, the water body is continuously circulated and stirred under the reflux, the mud and sand are fully mixed, and uniform mud and sand samples can also be obtained at the sampling port.

The mud and sand sampling system provided by the utility model has no agitating blades to avoid winding and wear. The principle of this system is to use high-pressure water jet mixing without traditional stirring blades, which avoids the fiber, cloth, hair in the water body from winding the stirring shaft and the gravel from wearing the blades. Protect the equipment and prolong the service life of the equipment.

The mixing effect is good, and the mud and sand are mixed more evenly. The reflux mixing system in this system adopts a unique design of the first nozzle and the second nozzle, which are arranged alternately on the front and rear pipelines. This strengthens the degree of turbulence in the sampling area, keeps the mud and sand in a suspended state, and effectively avoids their layered sedimentation.

Continuous large-volume sampling is possible. Time sampling is more accurate and scientific, and often requires long-term and large-volume sampling. The sampling system fully meets the requirements of large-volume sampling, and the sampling volume can reach 3-9m ³ .

Low operating costs. The jet flow power of the mud sand sampling system provided by the utility model completely depends on the water pump, fully utilizes the excess head of the water pump, and saves operating costs.

In summary, the utility model has the following advantages: in the mud sand sampling system provided by the utility model, the sampling port is arranged on the wall of the pool, the backflow stirring device is arranged at the bottom of the pool, and the water pump is respectively connected with the backflow stirring device and the sampling port, and the backflow The stirring device includes a pipe provided with a plurality of water spray nozzles. In the mud sand sampling system provided by the utility model, the pipeline with multiple water spray nozzles in the reflux stirring device is used to stir the water in the pool, and only simple assembly is required for large-volume sampling. Multiple water spray pipes are provided The pipe of the mouth, the stirring effect is good and the cost is low. The utility model has the advantages of long service life, convenient use and simple structure.
