Description

Technical Field

[0001] This utility model relates to the field of sampling technology, specifically a sampling device for water pollution detection. Background Technology

[0002] Water pollution is caused by harmful chemicals that damage aquatic ecosystems and drinking water sources. Wastewater contains acids, alkalis, heavy metals, and organic toxins, which can cause the death of aquatic organisms. Microorganisms decompose organic matter, consuming oxygen and causing water quality deterioration. To mitigate pollution, people take samples of treated wastewater for testing to ensure environmental safety.

[0003] A water pollution detection sampling device, disclosed in CN220542529U, includes a base plate and a push handle. The push handle is welded to the upper right end of the base plate. A filter box is installed at one end of the upper surface of the base plate, containing filter cotton. A water inlet trough is installed at the upper part of one side surface of the filter box. A water pump is fixedly installed at the middle of the upper surface of the base plate. A delivery pipe is fixedly installed in the water inlet trough, and the end of the delivery pipe is fixedly connected to the water pump. A support frame is welded to the other end of the upper surface of the base plate. A roller is movably fitted inside the support frame, and a winding roller is fitted on the outer surface of the roller. A motor is connected to the end of the roller away from the support frame. The advantages of this invention are: the device uses filter cotton, which can effectively filter impurities in the water, improving the sampling and detection effect; the device is equipped with a water pump and delivery pipe, which can quickly draw out and transport the water sample to the required location, improving sampling efficiency. Furthermore, existing sampling devices have the following disadvantages in use:

[0004] (1) Although the existing sampling device is equipped with wheels at the bottom to improve mobility, in the sampling site with rugged terrain, the four wheels often cannot provide enough stability and passability, and the mobility of the device will be severely limited, affecting work efficiency.

[0005] (2) Existing sampling devices use a rotating shaft to take in and put out the sampling tube. However, since the sampling tube is not fixed, it is difficult to take in and put out the sampling tube smoothly once there is insufficient friction, which is inconvenient to use.

[0006] (3) The existing sampling device is driven by two fixed rods. However, this design fails to take into account the height differences between different users. Since the height of the fixed rods is not adjustable, the applicability of the sampling device is limited, making it unsuitable for a wide range of users. Utility Model Content

Support column 701 and second support column 706 are welded to the top of the base plate 1. A connecting pipe 703 passes through the inside of support column 701. The rotating plate 702 is connected to the adjacent sides of support column 701 and second support column 706 by bearings. Several equidistant support shafts 704 are welded to the adjacent sides of the two rotating plates 702. A threaded groove 708 is formed on the side of support column 706 near the turntable 709. A rotating shaft 707 passes through support column 706. The turntable 709 is welded to the rotating shaft 707 away from support column 701. The turntable 709 is located away from the rotating shaft 710. A handle 710 is connected to a bearing on one side of the 07. A bolt 705 passes through the turntable 709.

The slider 604 is slidably connected to the slot 502. The locking block 603 can be completely accommodated in the slot 501. The locking block 603 is adapted to the slot 401. By setting an extension sleeve 4 and a push frame 5 and fixing them with the buckle structure 6, the locking block 603 can be pressed down to make it completely enter the slot 501. The height can be adjusted up and down, expanding the applicability of the sampling device and making it widely applicable to a variety of operators.

[0028] In practical use, refer to Figures 1 to 4 As shown, the sampling tube 8 is passed through the support shaft 704 and connected to the connecting pipe 703. The rotating turntable 709, driven by the handle 710, rotates the rotating plate 702 and the upper support shaft 704, converging the sampling tube 8 onto the support shaft 704. The bolt 705 is then turned into the threaded groove 708 to secure the device. The operation is simple and convenient. Pressing the locking block 603 retracts the telescopic rod 601 and spring 602, allowing the locking block 603 to enter the empty slot 501, which can be adjusted to a suitable height. When the telescopic rod 601 and spring 602 expand, they push the locking block 603 into the slot 401, fixing the pusher frame 5. This design is suitable for diverse operators. By setting an obstacle-crossing structure 3 and rotating the connecting seat 302... The device has a certain obstacle-crossing ability and can ensure mobility in sampling sites with rugged terrain. The extension and retraction of the damping rod 303 and spring 304 can provide shock absorption during the movement of the device. Push the device to the sampling location, rotate the fixing plate 204 of the fixing structure 2 to make the threaded column 203 descend, and the fixing plate 204 abuts the ground, fixing the device. Rotate the bolt 705 to make it leave the threaded groove 708. Rotate the turntable 709 through the handle 710 to drive the rotating plate 702 and the support shaft 704 above to rotate, and release the sampling tube 8 of the appropriate site. The suction pump 10 collects the water sample into the filter box 12 (the suction pump 10 and the filter box 12 are existing technologies and will not be described again) for sampling. The operation is simple.
