Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering sampling technology, specifically a water conservancy engineering sampling device. Background Technology

[0002] Sampling devices for water conservancy projects are equipment used to obtain water, soil or other environmental samples for analysis and detection of their components, pollutants or other characteristics. These sampling devices typically include sampling bottles, sampling instruments, level gauges and other tools. Appropriate sampling methods and equipment are selected as needed to ensure that accurate and reliable samples are obtained for analysis and research. In water conservancy projects, sampling devices are widely used to monitor water quality, soil quality and environmental changes.

[0003] Publication No.: CN219996618U, a water conservancy engineering sampling device, belonging to the field of water conservancy engineering technology, specifically includes a base and a sampling bucket. A column is fixedly mounted on the top of the base, and a telescopic frame is fixedly mounted on the column. A winding drum is fixedly mounted on the telescopic frame via a rotating shaft, and a traction rope is fixedly mounted on the winding drum. The free end of the traction rope is fixedly connected to the sampling bucket. An inlet tube is fixedly mounted at the bottom of the sampling bucket, and a sleeve is fitted on the outside of the inlet tube. A movable cylinder is connected inside the sleeve, and a filter head is provided at the bottom of the movable cylinder. This utility model, through the telescopic frame, rotating shaft, winding drum, and traction rope, can adjust the distance between the sampling bucket and the column, and can enable the sampling bucket to collect water quality samples at different depths, improving the accuracy of water quality testing results and enhancing the practicality of the device. Through the sleeve, movable cylinder, and filter head, sediment in the water can be filtered, preventing sediment from clogging the device and causing damage or even a reduction in its service life.

[0004] In summary, the existing technology CN219996618U uses a sampling bucket to sample water. However, during the sampling process, it is impossible to sample water at different heights simultaneously. Therefore, the sampling height needs to be adjusted multiple times, resulting in a long sampling time. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a water conservancy engineering sampling device, including a screw sleeve 2 and a fixing frame 3. A handle 4 is welded to the top of the fixing frame 3, allowing the fixing frame 3 to be moved using the handle 4. Bearings 12 are embedded on both sides of the fixing frame 3, and a lead screw 9 is fixedly installed within the inner ring of each bearing 12. Handwheels 8 are installed at both ends of the lead screw 9, allowing the lead screw 9 to be rotated using the two handwheels 8. Two screw sleeves 2 are engaged with the lead screw 9, and the outer threads of the lead screw 9 are distributed in opposite directions, allowing the two screw sleeves 2 to move relative to or in opposite directions on the rotating lead screw 9. A slider 11 is installed on the top of each screw sleeve 2. Two sliding grooves 10 are symmetrically opened at the top of the fixing frame 3 on both sides of the fixing plate 13. The two sliders 11 are slidably connected to the two sliding grooves 10 respectively, limiting the movement of the two screw sleeves 2. When the two screw sleeves 2 move, the two sliders 11 move within the two sliding grooves. The two screw sleeves 2 slide within the groove 10 to prevent them from shaking. A fixing plate 13 is welded to the top of the fixing bracket 3 on the opposite side of the two screw sleeves 2. A bearing 14 is embedded in the fixing plate 13. The screw rod 9 is fixedly connected to the inner ring of the bearing 14. The bearing 14 fixes the screw rod 9 to prevent it from shaking. A housing 1 is installed at the bottom of the screw sleeve 2 on one side of the fixing plate 13. A housing 7 is installed at the bottom of the screw sleeve 2 on the other side of the fixing plate 13. Four water storage tanks 5 are symmetrically opened on the inner side of both housing 1 and housing 7. Baffles 15 are symmetrically installed on the inner side of both housing 1 and housing 7. The baffles 15 separate the four water storage tanks 5 to prevent the water inside the four water storage tanks 5 from mixing together. Four water outlet pipes 6 are equidistantly embedded on the side of housing 7 away from housing 1. The four water outlet pipes 6 correspond to the four water storage tanks 5, and the water inside the four water storage tanks 5 can be discharged from the corresponding water outlet pipes 6.

[0023] Working principle: Use handle 4 to carry the fixing frame 3 to the sampling position of the water conservancy project. Insert the first shell 1 and the second shell 7 at the bottom of the fixing frame 3 into the water. Use handwheel 8 to turn screw 9. The two screw sleeves 2 move in opposite directions on the rotating screw 9. The two screw sleeves 2 drive the first shell 1 and the second shell 7 to separate. Water at different heights enters the corresponding water storage tank 5 from the openings on the opposite side of the first shell 1 and the second shell 7. After the four water storage tanks 5 are filled with water, use handwheel 8 to turn screw 9 in the opposite direction. The two screw sleeves 2 drive the first shell 1 and the second shell 7 to come together. Use handle 4 to take the first shell 1 and the second shell 7 out of the water and carry them into the sample analysis chamber. The water samples in the four water storage tanks 5 are discharged from the corresponding water outlet pipes 6 for analysis.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
