[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] Refer to Figures 1-5 , a sewage well water sampling tool, including an extension column 1, the extension column 1 is connected with an erection assembly, the erection assembly includes two fixed blocks 2 symmetrically arranged on the outer side wall of the extension column 1, and connecting shafts are provided on both fixed blocks 2, and a fixed frame 3 is rotatably sleeved on the outer side wall of the connecting shaft, which is used to support the entire water sampling tool and keep it stable. The fixed block 2 is fixed on the top of the extension column 1 by welding or bolts to ensure the firmness of the connection. The fixed frame 3 is connected to the fixed block 2 through the connecting shaft, and can rotate at a certain angle, so that the operator can adjust the direction of the sampling tool according to the actual situation;

[0024] Two symmetrically arranged adjustment grooves 4 are opened on the side wall of the extension column 1, and a plurality of U-shaped frames 5 are slidably connected to the inner side walls of the two adjustment grooves 4. Two symmetrically arranged first sockets 10 are provided on the U-shaped frame 5, and a plurality of second sockets 11 are provided on the adjustment grooves 4. The plurality of second sockets 11 are arranged vertically. The same bolt 12 is provided in the corresponding first socket 10 and second socket 11. When sampling at a deeper position is required, the U-shaped frame 5 can be moved downward to a suitable height and fixed by the bolt 12; on the contrary, if sampling at a shallower position is required, the U-shaped frame 5 can be moved upward. This design enables the sampling tool to sample at different depths, greatly improving its applicability and flexibility;

[0025] A rotating shaft 6 is rotatably connected to the inner side wall of the U-shaped frame 5, and the rotating shaft 6 is connected to a water intake mechanism. The water intake mechanism includes a rotating cylinder 7 fixedly connected to the outer side wall of the rotating shaft 6. A sealing cover 8 is connected to the outer side wall of the rotating shaft 6. The sealing cover 8 is not affected when the rotating shaft 6 rotates. When the water storage tank 9 of the rotating cylinder 7 is directly below the sealing cover 8, the water storage tank 9 is sealed.

[0026] The sealing cover 8 and the rotating cylinder 7 are of matching sizes. The rotating cylinder 7 is provided with a water storage tank 9. The rotating cylinder 7 is connected to the U-shaped frame 5 through the rotating shaft 6 and can rotate around the rotating shaft 6. The sealing cover 8 and the rotating cylinder 7 are of matching sizes and can seal the water storage tank 9 during the sampling process to prevent contact with sewage at other depths during the upward movement after water intake, which affects the accuracy of sampling. During sampling, the water storage tank 9 is exposed, and then the sampling tool is placed into the sewage. After the water storage tank 9 is filled with water samples, the rotating cylinder 7 is rotated through the rotating shaft 6 to make the sealing cover 8 seal the water storage tank 9, thus completing the sampling process. This design ensures the integrity and accuracy of the water samples.

[0027] The rotating shaft 6 is connected to the extension column 1 through a meshing mechanism. The meshing mechanism includes two gears 13 fixedly connected to the outer side wall of the rotating shaft 6. The two gears 13 are distributed on both sides of the sealing cover 8. The extension column 1 is provided with a lifting groove 14. The inner side wall of the lifting groove 14 is slidably connected to a lifting plate 15. Two groups of racks 16 are fixedly connected to the outer side wall of the lifting plate 15. The gears 13 are meshed with the racks 16. The gears 13 are fixed on the rotating shaft 6, while the racks 16 are fixed on the lifting plate 15. When the lifting plate 15 moves up and down, it will drive the racks 16 to move accordingly, and then drive the gears 13 to rotate. The lifting plate 15 can be moved upward through an adjusting mechanism. At this time, the racks 16 will also rise, driving the gears 13 to rotate, so that the sealing cover 8 closes the water storage tank 9. Conversely, when the water intake mechanism needs to be opened, the lifting plate 15 can be moved downward, and then the water storage tank 9 faces outward.

[0028] The extension column 1 is provided with an adjusting mechanism. The adjusting mechanism includes a pressing groove 17 opened on the extension column 1. The inner side wall of the pressing groove 17 is fixedly connected to a sliding rod 18. The outer side wall of the sliding rod 18 is slidably connected to a pressing plate 19. The end of the pressing plate 19 is fixedly connected to the outer side wall of the lifting plate 15. A return spring 20 is sleeved on the outer side wall of the sliding rod 18. The two ends of the return spring 20 are respectively fixedly connected to the outer side wall of the bottom of the pressing plate 19 and the inner side wall of the pressing groove 17.

[0029] The specific working principle of the present utility model is as follows:

[0030] During the actual operation process, when this device is in use, first place the fixing frame 3 on the edge of the sewage well, and use the connecting shaft between the fixing frame 3 and the fixing block 2 to ensure the stability of the entire device. Then, adjust the position of the U-shaped frame 5 according to the actual depth of the sewage well. By inserting the pin 12 into the corresponding first socket 10 and second socket 11, the up and down movement of the U-shaped frame 5 in the adjustment slot 4 can be realized, thereby adjusting the height of the water intake mechanism, and then water can be taken from positions at different heights. When it is necessary to take a water sample, the operator presses the pressing plate 19. At this time, the pressing plate 19 moves inward along the sliding rod 18 and compresses the return spring 20, and at the same time drives the lifting plate 15 to move downward, so that the rack 16 connected to the lifting plate 15 also moves downward. Due to the meshing relationship between the gear 13 and the rack 16, the downward movement of the rack 16 will drive the gear 13 to rotate, and then drive the rotating shaft 6 and the water intake mechanism connected thereto to rotate. When the rotating cylinder 7 rotates to the position where the opening faces downward, sewage can enter the rotating cylinder 7 through the water storage tank 9; when it is necessary to close the water intake, the operator releases the pressing plate 19, the return spring 20 returns to its original state, and pushes the pressing plate 19, the lifting plate 15 and the rack 16 to move upward, and the gear 13 rotates again, so that the rotating cylinder 7 rotates to the position where the sealing cover 8 is aligned with the opening of the rotating cylinder 7, thus completing the process of taking the water sample. The entire process of taking the water sample realizes the opening and closing of the water intake mechanism by manually controlling the pressing plate 19, realizes the sealing of the water storage tank 9, and avoids the rotating cylinder 7 contacting water at different depths during the upward movement, which affects the accuracy of sampling.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
