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.
[0020] To address the problem of how to effectively sample, such as Figure 1-4 As shown, the following preferred technical solutions are provided:
[0021] A sampling device for surface water detection includes a sampling rod 1. The sampling rod 1 has several evenly distributed storage slots 15 inside along its axial direction. Several rectangular boxes 12, corresponding to the storage slots 15, are fixed to the outer periphery of the sampling rod 1 along its axial direction. The bottom surface of each rectangular box 12 has a water inlet hole 14 communicating with the storage slots 15. A locking block 11 is movably disposed inside each rectangular box 12. A motor 5 is mounted on the upper end of the sampling rod 1. A lead screw 6 is mounted at the output end of the motor 5. A connecting plate 9 is sleeved on the outer side of the lead screw 6. The connecting plate 9 drives several locking blocks 11 to reciprocate synchronously along a straight line, used to open and close the rectangular boxes 12. A water outlet pipe 16 is provided at the water outlet end of each storage slot 15, and a sealing cap 19 is detachably installed at the end of the water outlet pipe 16.
[0022] Specifically, surface water sampling is required. The sampling rod 1 is held and vertically inserted into the water at the sampling point. Then, the motor 5 drives the lead screw 6 to rotate, causing the connecting plate 9 to move horizontally in a straight line. This, in turn, causes several locking blocks 11 to move horizontally in a straight line simultaneously, moving outwards from their corresponding rectangular boxes 12, opening the rectangular boxes 12. Water at different depths then enters the corresponding rectangular boxes 12, flowing through the inlet hole 14 into the corresponding storage tank 15. The motor 5 then drives the lead screw 6 to reverse, causing the locking blocks 11 to move in the opposite direction and reset back into the rectangular boxes 12, sealing them. The sampling rod 1 is then removed from the water, and the sealing cap 19 is rotated off. Water from the storage tanks 15 at different locations is then extracted, bottled, and tested. This design allows for simultaneous sampling of water samples from different depths, offering a simple and efficient operation.
[0023] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:
[0024] A support plate 2 is fixed at the top of the sampling rod 1. A T-slot 7 is opened at the bottom of the support plate 2. A T-block 8 is fixed at the end of the connecting plate 9. The T-block 8 is slidably connected to the inner surface of the T-slot 7. A fixing plate 4 is fixed at the bottom edge of the support plate 2. The motor 5 is fixedly installed on the side of the fixing plate 4 and its output end extends and is fixedly connected to the end of the lead screw 6. The lead screw 6 is threadedly connected to the inner side of the end of the connecting plate 9. A connecting post 10 is fixed on the side of the locking block 11. The end of the connecting post 10 is fixed on the side of the connecting plate 9. The purpose of this design is that the motor 5 drives the lead screw 6 to rotate, which drives the connecting plate 9 to reciprocate along a straight line, thereby driving several locking blocks 11 to move synchronously.
[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the following preferred technical solutions are provided:
[0026] A sealing gasket 13 is attached to the inside of the rectangular box 12. The locking block 11 and the inside of the rectangular box 12 with the sealing gasket 13 are interlocked and matched in size. The purpose of this design is to ensure airtightness. The rectangular box 12 is opened and closed by moving the locking block 11, which facilitates water flow and sealed storage.
[0027] Furthermore, such as Figure 2 and Figure 4 As shown, the following preferred technical solutions are provided:
[0028] The water inlet of the water outlet pipe 16 is fixedly connected to the side wall of the storage tank 15. The outer side of the water outlet of the water outlet pipe 16 is threaded to the inner side of the sealing cover 19. The outer side of the sealing cover 19 is machined with anti-slip texture. The purpose of this design is to take out the water in the corresponding storage tank 15 through the water outlet pipe 16 and open and close the water outlet pipe 16 through the sealing cover 19.
[0029] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0030] A limiting ring 17 is fixed on the outside of the water outlet pipe 16, and a sealing gasket 18 is attached to the side of the limiting ring 17. The sealing gasket 18 is sleeved on the outside of the water outlet pipe 16. The purpose of this design is to rotate and tighten the sealing cover 19 so that the sealing cover 19 squeezes and deforms the sealing gasket 18, thus ensuring the sealing performance.
[0031] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0032] A handle 3 is fixed to the upper end of the support plate 2. The outer side of the handle 3 is machined with anti-slip texture. The purpose of this design is to facilitate carrying the sampling rod 1 through the handle 3 and to facilitate inserting the sampling rod 1 into the water for sampling.
[0033] In summary: For surface water sampling, the sampling rod 1 is held and vertically inserted into the water at the sampling point. Then, the motor 5 drives the lead screw 6 to rotate, causing the connecting plate 9 to move horizontally in a straight line. This, in turn, causes several locking blocks 11 to move horizontally in a straight line simultaneously, moving outwards from their corresponding rectangular boxes 12, opening the boxes. Water at different depths then enters the corresponding rectangular boxes 12, flowing through the inlet 14 into the corresponding storage tanks 15. The motor 5 then drives the lead screw 6 to reverse, causing the locking blocks 11 to move in the opposite direction and reset back into the rectangular boxes 12, sealing them. The sampling rod 1 is then removed from the water, and the sealing cap 19 is rotated off. Water from the storage tanks 15 at different locations is then extracted, bottled, and tested. This design allows for simultaneous sampling of water at different depths, offering a simple and efficient operation.
