[0029] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a water sampling device for a fixed depth, including a circular frame 1, a telescopic column 2 slidably disposed on the inner wall of the circular frame 1, a motor 3 fixedly disposed on the top of the circular frame 1, and a threaded rod 4 fixedly disposed on the bottom of the rotating shaft of the motor 3 extending into the interior of the circular frame 1.

[0031] The bottom end of the threaded rod 4 extends into the interior of the telescopic column 2. A storage frame 5 is fixedly installed at the bottom end of the telescopic column 2. A submersible pump 6 is fixedly installed on the side of the storage frame 5. A sealing element 7 is slidably installed at the bottom of the storage frame 5. Three long grooves 8 are opened on the side of the storage frame 5. A moving strip 9 is slidably installed inside the long grooves 8.

[0032] Working principle: When using this fixed-depth water sampling device, after the water to be tested inside the storage frame 5 is tested, the T-shaped plate 904 is pressed inward, compressing the second compression spring 901 and causing the horizontal plate of the T-shaped plate 904 to move out from the horizontal groove of the T-shaped slot 705, thereby releasing the T-shaped plate 904 from the sealing plate 701. Then, the three moving strips 9 move upward, compressing the first compression spring 902, quickly separating the sealing plate 701 from the storage frame 5, thereby quickly cleaning the water impurities remaining on the upper side of the inner wall of the sealing plate 701 and the filter plate 703, reducing the possibility of clogging of the water sampling device.

[0033] By moving the sealing plate 701 to the lower side of the inner wall of the storage frame 5, the three moving strips 9 are positioned on the lower side of the inner wall of the long groove 8 by the contact force of the first compression spring 902. Then, the T-shaped plate 904 is squeezed, causing the second compression spring 901 to compress. The moving strips 9 then move the T-shaped plate 904 to contact the inside of the slot 705. Next, the T-shaped plate 904 is released, so that the horizontal plate and the vertical plate of the T-shaped plate 904 are both engaged inside the slot 705 by the rebound force of the second compression spring 901. The sealing plate 701 can be quickly fixed to the bottom of the storage frame 5, thereby quickly sampling the water.

[0034] It should be noted that the sealing element 7 includes a sealing plate 701, which is slidably disposed at the bottom of the inner wall of the storage frame 5. Four support blocks 702 are fixedly disposed on the top of the sealing plate 701, a filter plate 703 is fixedly disposed on the top of the four support blocks 702, and three connecting strips 704 are fixedly disposed on the bottom of the sealing plate 701.

[0035] By adopting the above technical solution, the filter plate 703 can filter impurities in the water, increasing the convenience of testing after water sampling.

[0036] It should be noted that the shape of the moving strip 9 and the inner wall of the long groove 8 are both T-shaped. A first compression spring 902 is fixedly installed on the top of the moving strip 9. One end of the first compression spring 902 is fixedly engaged with the top of the inner wall of the long groove 8. A rectangular groove 903 is opened on the side of the moving strip 9. A T-shaped plate 904 is slidably installed inside the rectangular groove 903. A slot 705 that mates with the T-shaped plate 904 is opened on the side of the connecting strip 704.

[0037] By using the above technical solution, when the T-shaped plate 904 is squeezed, the horizontal plate of the T-shaped plate 904 moves out from the inside of the horizontal groove of the slot 705 with an internal cross-section of T, and can contact the fixation between the storage frame 5 and the sealing plate 701.

[0038] It should be noted that a second compression spring 901 is fixedly installed on the side of the vertical plate of the T-shaped plate 904. One end of the second compression spring 901 is fixedly engaged with the inside of the rectangular groove 903. The slot 705 is T-shaped, and the inside of the T-shaped slot 705 is slidably engaged with the side of the T-shaped plate 904.

[0039] By adopting the above technical solution, when the T-shaped plate 904 moves to the inner wall of the slot 705, it is convenient to fix the sealing plate 701 to the lower side of the storage frame 5.

[0040] It should be noted that a ball valve 706 is fixedly inserted into the middle of the bottom surface of the sealing plate 701, and a connecting ring 707 is fixedly installed at the bottom of the sealing plate 701. The side of the connecting ring 707 is fixedly engaged with the side of the three connecting strips 704.

[0041] Using the above technical solution, the water sampled can be easily discharged by opening the ball valve 706.

[0042] It should be noted that two movable blocks 201 are fixedly installed on the side of the telescopic column 2, and a movable groove 202 that cooperates with the movable blocks 201 is opened inside the circular frame 1. A scale groove 101 is fixedly installed on the front side of the circular frame 1, and a scale ruler 203 is fixedly installed on the side of the front movable block 201. The side of the scale ruler 203 slides in cooperation with the inside of the scale groove 101.

[0043] Using the above technical solution, when sampling is required, the rotating shaft of the motor 3 drives the threaded rod 4 to rotate. At the same time, the moving block 201 and the moving groove 202 limit the telescopic column 2, so that the threaded rod 4 drives the telescopic column 2 to move downward when rotating, which in turn drives the scale 203 to move downward. The scale 203 allows the staff to easily know the length of the telescopic column 2 moving downward, which in turn allows the telescopic column 2 to drive the storage frame 5 to move underwater to a suitable depth for water sampling.

[0044] It should be noted that a floating airbag 102 is fixedly fitted to the side of the circular frame 1, and the top of the floating airbag 102 is rounded.

[0045] Using the above technical solution, the floating airbag 102 enables the water sampling device to float on the water surface.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
