[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, the present invention provides a water source sampling device for water conservancy testing, comprising a mounting frame 1, a winding roller 2, a connecting belt 3, a sampling bucket 4, a telescopic rod 5, and a limiting frame 6. The device is characterized in that: the winding roller 2 is movably connected to the bottom of the mounting frame 1; the connecting belt 3 is fixedly connected to the surface of the winding roller 2; the telescopic rod 5 is fixedly installed on the top right side of the mounting frame 1; the limiting frame 6 is fixedly installed on the top of the mounting frame 1 and the output end of the telescopic rod 5; the connecting belt 3 passes through the interior of the limiting frame 6; the sampling bucket 4 is fixedly installed on the other end of the connecting belt 3; a bucket lid 7 is threadedly connected to the top of the sampling bucket 4; a water inlet 8 is opened on the front side of the top of the bucket lid 7; a sealing airbag 9 is installed inside the water inlet 8; an air pipe 10 is connected to the top of the sealing airbag 9; a fixing component 11 is fixedly connected to the rear side of the top of the bucket lid 7; and an installation component 12 is fixedly connected to the bottom of the surface of the bucket lid 7.

[0024] refer to Figure 3 The fixing component 11 includes a fixing block 111, which is fixedly connected to the rear side of the surface of the bucket lid 7. An mounting block 112 is fixedly installed on the front side of the fixing block 111 by bolts. An arc groove 113 is provided on the back side of the mounting block 112 and the front side of the fixing block 111. The air pipe 10 is located inside the arc groove 113.

[0025] As a technical optimization of this utility model, by setting the fixing component 11, the position of the air tube 10 can be effectively fixed, preventing the air tube 10 and the sealing airbag 9 from getting tangled or shifting during operation, ensuring that the sealing airbag 9 can always be located inside the water inlet 8. The design of the arc groove 113 can fit the air tube 10 better, reducing the risk of the air tube 10 being damaged due to pulling.

[0026] refer to Figure 3 The mounting component 12 includes a threaded strip 121, which is fixedly connected to the bottom of the surface of the barrel cover 7. The inner wall of the sampling barrel 4 is provided with a threaded groove 122 that is used in conjunction with the threaded strip 121. The barrel cover 7 is threadedly connected to the sampling barrel 4 through the threaded groove 122 and the threaded strip 121.

[0027] As a technical optimization of this utility model, by setting the installation component 12, the threaded strip 121 is used in conjunction with the threaded groove 122 on the inner wall of the sampling bucket 4, making the connection between the bucket cover 7 and the sampling bucket 4 tighter and more stable. This structural design is simple and easy to implement, and facilitates quick disassembly and maintenance. The threaded connection enhances the sealing performance between the bucket cover 7 and the sampling bucket 4, effectively preventing damage to the purity and accuracy of the sample.

[0028] refer to Figure 1 An air pump 13 is provided at the end of the trachea 10 away from the sealing airbag 9, and the output end of the air pump 13 is connected to the trachea 10.

[0029] As a technical optimization of this utility model, by setting an air pump 13 to provide a stable air source for the sealing airbag 9, it is ensured that the sealing airbag 9 can be quickly inflated and maintain sufficient pressure to seal the water intake 8. This design improves sampling efficiency and reduces the complexity of manual operation. The configuration of the air pump 13 can also realize remote control of the inflation and deflation process of the sealing airbag 9, further reducing the difficulty and risk of operation.

[0030] refer to Figure 3 A counterweight 14 is fixedly connected to the bottom of the sampling bucket 4.

[0031] As a technical optimization of this utility model, adding a counterweight 14 to the bottom of the sampling bucket 4 can increase the stability of the entire device in water and prevent the device from floating or tilting due to factors such as water flow during the sampling process. The presence of the counterweight 14 helps to keep the sampling bucket 4 perpendicular to the water surface, thereby improving the accuracy and representativeness of the sampling.

[0032] refer to Figure 1 The surface of the sampling bucket 4 is connected to a water outlet valve 15.

[0033] As a technical optimization of this utility model, by setting a water outlet valve 15, the operator can conveniently discharge the water sample after sampling, avoiding the cumbersome steps of opening the entire sampling bucket 4 to take water and drain water. This not only simplifies the operation process, but also reduces the possibility of water sample contamination.

[0034] refer to Figure 1 A support plate 16 is fixedly connected to the right side of the mounting bracket 1, and the air pump 13 is fixedly installed on the top of the support plate 16.

[0035] As a technical optimization of this utility model, by setting a support plate 16, the air pump 13 is fixed on the support plate 16 on the right side of the mounting frame 1, which is conducive to the compact layout of the overall structure, saves space and improves the overall aesthetics of the device. The air pump 13 is located on the support plate 16, which facilitates daily inspection and maintenance and extends the service life of the equipment.

[0036] The working principle and usage process of this utility model are as follows: During use, the operator installs the mounting frame 1 on the bank of the water source to be tested. When sampling deeper water is required, the operator starts the air pump 13, which inflates the sealing airbag 9 through the air pipe 10. This seals the water intake 8 with the inflated airbag 9. The operator then extends the output end of the telescopic rod 5 outwards, causing the connecting belt 3 to extend outwards via the limiting frame 6. This allows the sampling bucket 4 to move to the water surface along with the connecting belt 3. The operator then unwinds the winding roller 2, and the sampling bucket 4 is vertically lowered into the water via the counterweight 14. Because the sealing airbag 9 seals the water intake 8, water will not enter the sampling bucket 4 during the water entry process. After descending to a suitable depth, the operator disconnects the air pipe 10 connected to the air pump 13, thereby deflating the sealing airbag 9 and removing it from the water intake 8. This allows water to enter the sampling bucket 4 for sampling, enabling the sampling bucket 4 to sample water sources at different depths. After sampling, the operator rotates the winding roller 2 to drive the connecting belt 3 to wind up, causing the connecting belt 3 to move the sampling bucket 4 upwards to the water outlet surface. Then, the operator controls the telescopic rod 5 to retract, thus completing the sampling work. When the operator needs to take samples from the sampling bucket 4 for testing, they can take the water source sample from the sampling bucket 4 by opening the water outlet valve 15, ensuring convenient testing for the operator.

[0037] In summary, this water source sampling device for water conservancy testing, by setting up a bucket lid 7, a water inlet 8, a sealing airbag 9, an air pipe 10, and an installation assembly 12, allows the bucket lid 7 to be fixedly installed to the sampling bucket 4 via the installation assembly 12. During deep water sampling, the operator injects air into the air pipe 10, causing the sealing airbag 9 to expand and seal the water inlet 8. This allows the sampling bucket 4 to descend to different depths without water entering. When the desired sampling depth is reached and water needs to be collected, the operator simply needs to prevent the sealing airbag 9 from being lifted, allowing water to enter the sampling bucket 4 through the water inlet 8 for sampling. This ensures the operator's convenience in sampling at different depths and solves the problem that in practical use, the aforementioned devices do not have a structure for sampling water sources at different depths, thus only allowing surface sampling. When the operator needs to test water samples at different depths, the aforementioned devices are limited in their ability to perform this task.
