DETAILED DESCRIPTION

[0020] This specific embodiment is a survey sampling device, such as Figure 1-Figure 5 As shown, the survey sampling device includes a sampling tube 1, a sampling cup 2 and a sealing block 3. A plurality of sampling cups 2 are arranged in sequence inside the sampling tube 1 along the vertical direction. The sealing block 3 matches the inner wall of the sampling tube 1. A fixing rod 4 is bonded to the bottom surface of the inner part of the sampling cup 2. A sealing cover 5 is movably sleeved on the fixing rod 4 and matches the open end of the sampling cup 2. The lower surfaces of the sampling cup 2 and the sealing block 3 near the upper side are connected with a threaded rod 6, which matches the thread groove at the upper end of the fixing rod 4. A mounting plate 7 is fixed to the inner wall of the sampling cup 2, and a water pump 8 is installed on the mounting plate 7. A plurality of sampling holes are opened on the surface of the sampling tube 1. The water inlet end of the water pump 8 is connected to a sampling hose 9. The movable end of the sampling hose 9 passes through the sampling cup 2 and cooperates with the sampling holes. A filter screen 10 is arranged inside the sampling hose 9. The water outlet end of the water pump 8 is connected to a water outlet pipe, which cooperates with the inner cavity of the sampling cup 2. A liquid level sensor 11 is installed on the lower surface of the mounting plate 7, and a tube cover 12 is threadedly matched with the upper port of the sampling tube 1.

[0021] Through the threaded cooperation between the threaded rod 6 and the threaded groove at the upper end of the fixed rod 4, it is convenient to stably connect several sampling cups 2 together. Combined with the mutual cooperation between the water pump 8 and the sampling hose 9, and the mutual cooperation between the sampling hose 9 and the sampling hole, under the action of the water outlet pipe, it is convenient to extract the water sample into the sampling cup 2. Several sampling cups 2 arranged in the vertical direction realize simultaneous sampling of water layers at different depths, effectively reducing the workload of the staff and improving the sampling efficiency. Combined with the liquid level sensor 11, it is convenient to monitor the changes in the liquid level inside the sampling cup 2 in real time to prevent overflow caused by excessive water sample in the sampling cup 2. The sealing cover 5 ensures the sealing of the upper port of the sampling cup 2. Combined with the sealing block 3 and the tube cover surface 12, it further ensures the sealing of the sampling tube 1, effectively preventing the water sample from splashing and mixing, affecting the later research data.

[0022] A sleeve 19 is welded to the outside of the threaded rod 6 and cooperates with the upper surface of the sealing cover 5. Through the cooperation between the sleeve 19 and the sealing cover 5, when the threaded rod 6 is screwed into the fixed rod 4, the sealing cover 5 is pressed toward the sampling cup 2, thereby ensuring the stability and sealing effect between the sealing cover 5 and the open end of the sampling cup 2.

[0023] A counterweight 17 is welded to the lower end of the sampling tube 1, and an installation groove is opened at the bottom of the counterweight 17. A camera 16 is installed inside the installation groove, and a transparent cover is installed on the outer side of the inner wall of the installation groove to cooperate with the camera 16. The counterweight 17 ensures that the sampling tube 1 always remains vertically downward in the water, ensuring the stability of the sampling tube 1 during the deep underwater process. The combination of the transparent cover and the camera 16 facilitates the collection of underwater images, further facilitating the collection of water samples and hydrogeological research.

[0024] A plurality of sealing grooves are provided on the inner wall of the sampling tube 1, and a plurality of sealing strips are provided on the outer surface of the sealing block 3, which cooperate with the sealing grooves. A handle 18 is bonded to the upper surface of the sealing block 3. The cooperation between the sealing strip and the sealing groove effectively increases the sealing performance between the sealing block 3 and the inner wall of the sampling tube 1. The handle 18 facilitates pulling the sealing block 3 outward, thereby facilitating taking out the sampling cup 2 from the inside of the sampling tube 1.

[0025] A rubber block 13 is bonded to the inner wall of the cylinder cover 12, which cooperates with the inner wall of the sampling cylinder 1, and the rubber block 13 effectively increases the sealing between the cylinder cover 12 and the open end of the sampling cylinder 1. A fixing ring 14 is welded on the upper surface of the cylinder cover 12, and a steel rope 15 is connected to the fixing ring 14, which facilitates the lowering of the sampling cylinder 1 to water layers of different depths.

[0026] Working principle: When using the survey sampling device of the technical solution, first screw the threaded rod 6 into the corresponding threaded groove at the upper end of the fixed rod 4 in sequence. As the threaded rod 6 is screwed in, the sleeve 19 is driven to move in the direction close to the sealing cover 5 until the threaded rod 6 is screwed in to the bottom. Under the action of the sleeve 19, the sealing cover 5 is tightly pressed against the open end of the sampling cup 2. At the same time, the connected sampling cup 2 is placed into the sampling tube 1 through the handle 18, and the sealing strip on the sealing block 3 is stuck in the corresponding sealing groove. At the same time, the movable end of the sampling hose 9 is pulled out through the sampling hole so that the open end of the sampling hose 9 faces outward. Finally, the tube cover 12 is screwed on the open end of the sampling tube 1, and the rubber block 13 is squeezed on the inner wall of the sampling tube 1. The sampling tube 1 is installed. When conducting survey sampling operations, the device is carried to the sampling site, and the sampling tube 1 is placed in the water layer to be sampled, and the steel rope 15 is released. Under the gravity of the block 17, the sampling tube 1 sinks vertically downward into the water, and the underwater image is collected by the camera 16 during the sinking process to ensure the stability of the sampling tube 1 sinking process; when the sampling tube 1 sinks to a suitable depth, the steel rope 15 stops releasing, and the water pump 8 is driven to run at this time. Under the action of the sampling hose 9, the water sample is extracted, and under the action of the outlet pipe, it is drained into the sampling cup 2. Combined with the liquid level sensor 11, the water level change inside the sampling cup 2 is monitored in real time, and the pumping operation of the water pump 8 is stopped in time. Under the action of several sampling cups 2, the sampling operation of water layers at different depths is completed; at this time, the steel rope 15 is wound up, the sampling tube 1 is pulled out of the water, and the above steps are reversed to take out the sampling cup 2 and the water sample inside it; wherein the filter net 10 effectively filters the water sample to prevent the water from containing large particles of impurities, which may cause the sampling hose 9 and the water pump 8 to be blocked, affecting the use.

[0027] The movable end of the steel rope 15 is connected to an external winch, which is convenient for releasing and winding the steel rope 15, and further convenient for lowering the sampling tube 1 to the water layer and collecting the sampling tube 1 after the sampling is completed. When the steel rope 15 is released by the external winch, the released length of the steel rope 15 is measured to determine the sinking depth of the sampling tube 1, and then the sampling depths of different sampling cups 2 are obtained.

[0028] The utility model facilitates simultaneous sampling of water layers of different depths by means of a plurality of sampling cups 2 arranged in a vertical direction, effectively reduces the workload of staff members who need to perform multiple sampling of water layers of different depths, and improves sampling efficiency.

[0029] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. In the utility model, the water pump 8 and the liquid level sensor 11 are connected to the external control structure to facilitate the operation and use of the staff. The above-mentioned components are all purchased on the market, and technical personnel in this field can install and use them according to requirements.

[0030] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation scheme of the utility model. In addition, the utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the utility model.
