[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figures 1-3 This utility model provides a water quality sampling device for environmental pollution detection, comprising: a frame 1, the upper end of the frame 1 having a first threaded hole 101, the first threaded hole 101 being threadedly connected to a plurality of first connecting pipes 10 or second connecting pipes 11; a cone head 2 being fixedly connected to the lower end of one side of the frame 1; a connecting shaft 3 being fixedly connected to the middle of the upper end of the frame 1 on one side of the cone head 2, the other end of the connecting shaft 3 being slidably connected to a connecting frame 4, the connecting frame 4 being L-shaped, and a symmetrical front fixing device 6 being fixedly connected to the inner surface of the other side of the L-shaped connecting frame 4, each of the symmetrical front fixing devices 6 being fixedly connected to a rear fixing device 7 via a fixing shaft 703, and a plurality of collection pipes 9 being installed between the corresponding rear fixing device 7 and the front fixing device 6.

[0024] Further as Figure 1 As shown, it is worth noting that each of the first connecting pipes 10 has a third threaded hole 1002 at its upper end, and each of the first connecting pipes 10 has a threaded head 1001 at its lower end. One end of the second connecting pipe 11 also has a threaded head 1001. The threaded head 1001 can be threaded to the third threaded hole 1002 or the first threaded hole 101. The several first connecting pipes 10 or second connecting pipes 11 that can be freely installed and disassembled and are threaded through the first threaded hole 101 at the upper end of the frame 1 can control the length of use according to the actual situation, thereby facilitating the work of sampling personnel and increasing the practicality of the environmental pollution detection water quality sampling device.

[0025] Further as Figure 1 As shown, it is worth noting that both sides of the lower end of the cone 2 are arc-shaped, and the upper end of the cone 2 is rounded. The shape of the cone 2 makes it easier for the frame 1 to enter the water without causing too much change in the water quality, thus affecting the test results.

[0026] The working process of this scheme is as follows: First, place the two collection tubes 9 into the arcs opposite to the front fixing device 6 and the rear fixing device 7 respectively. Then, rotate the fixing shaft 703. The fixing shaft 703 drives the rear fixing device 7 to move towards the front fixing device 6 until the two collection tubes 9 are fixed. Then, install an appropriate number of first connecting tubes 10 and second connecting tubes 11 as needed. Finally, slowly put the frame 1 into the polluted water. Because the connection between the connecting frame 4 and the connecting shaft 3 is a sliding connection, and the connection position between the connecting frame 4 and the connecting shaft 3 is at the upper end of one side of the connecting frame 4, and a foam board 5 is fixedly connected to the outer surface of the other side of the connecting frame 4, when the frame 1 enters the water, the foam board 5 will drive the connecting frame 4 to float horizontally, and sampling of the polluted water source can begin. When the collection is completed and the frame is pulled up, the weight of the counterweight 8 will keep the collection tubes 9 in a vertical state, so that the samples collected in the collection tubes 9 will not scatter.

[0027] As can be seen from the above working process, several first connecting pipes 10 or second connecting pipes 11 that can be freely installed and disassembled are connected by the first threaded hole 101 at the upper end of the frame 1. The length of use can be controlled according to the actual situation, which facilitates the work of sampling personnel and increases the practicality of the environmental pollution detection water quality sampling device. The shape of the cone head 2 makes it easier for the frame 1 to enter the water without causing too much change in water quality, thus affecting the test results.

[0028] Further as Figure 1 and Figure 2 As shown, it is worth noting that the connecting frame 4 is L-shaped. A connecting shaft 3 is slidably connected to the upper end of one side of the L-shaped connecting frame 4, and a foam board 5 is fixedly connected to the outer surface of the other side of the L-shaped connecting frame 4. A counterweight 8 is fixedly connected to the lower end of the other side of the L-shaped connecting frame 4. The lower end of the counterweight 8 fits and slides on the upper arc surface of the cone head 2. The connection between the connecting frame 4 and the connecting shaft 3 is a sliding connection. The connection position between the connecting frame 4 and the connecting shaft 3 is at the upper end of one side of the connecting frame 4, and the foam board 5 is fixedly connected to the outer surface of the other side of the connecting frame 4. That is, when the device is put into water, the foam board 5 will drive the connecting frame 4 to float horizontally, which makes it easier to sample polluted water sources. After collection, when it is pulled up, the weight of the counterweight 8 will keep the collection tube 9 in a vertical state, so that the sample collected in the collection tube 9 will not scatter, thereby increasing the practicality of the environmental pollution detection water quality sampling device.

[0029] Further as Figure 1 and Figure 2As shown, it is worth noting that each of the symmetrical front fixing devices 6 includes a first connecting plate 601. One side of the first connecting plate 601 is provided with a symmetrical arc, and the upper and lower ends of the first connecting plate 601 located in the middle of the symmetrical arc are fixedly connected with limit posts 605. The other end of each limit post 605 is fixedly connected with a connecting block 606. The first connecting plate 601 is provided with a second threaded hole 604 at the center point of the middle of the symmetrical arc. The symmetrical collection tubes 9 can be fixed more conveniently through the front fixing device 6 and the rear fixing device 7, so that sampling can be carried out simultaneously in one place, preventing the randomness of sample detection, thus improving the efficiency of detection quality, and thereby improving the practicality of the environmental pollution detection water quality sampling device.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that each of the symmetrical rear-mounted fixing devices 7 includes a second connecting plate 701. One side of the second connecting plate 701 is provided with a symmetrical arc, and both the upper and lower ends of the second connecting plate 701 located in the middle of the symmetrical arc are provided with through holes 711 and sliding grooves 709. The through holes 711 and sliding grooves 709 are respectively fitted and slidably connected to the outer surface of the limiting post 605 or the connecting block 606. The second connecting plate 701 is provided with a connecting hole 710 at the center point of the middle of the symmetrical arc. The connecting hole 710 is slidably connected to a fixing shaft 703. By fitting and slidably connecting the through holes 711 and sliding grooves 709 to the outer surface of the limiting post 605 or the connecting block 606, the position and movement trajectory of the symmetrical rear-mounted fixing device 7 can be restricted.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that one end of the fixed shaft 703 is threaded to the second threaded hole 604, and the fixed shaft 703 is slidably connected to the outer surface of the second connecting plate 701 on the other side by a sliding baffle 704, a slidably connected spring 706, a fixed baffle 705, and a fixed handle 707. Through the position and connection relationship of the second connecting plate 701, the sliding baffle 704, the spring 706, and the fixed baffle 705, the collecting tube 9 can have a certain buffering effect to prevent damage when the collecting tube 9 is fixed. In addition, the fixed handle 707 facilitates the rotation of the fixed shaft 703.

[0032] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the second connecting plate 701 and the first connecting plate 601 are each provided with a second rubber pad 702 or a first rubber pad 602 on the inner surface of the symmetrical arc. The second connecting plate 701 and the first connecting plate 601 are each provided with a limiting groove 708 or a raised guide 603 on both sides of their opposite surfaces. The raised guide 603 and the limiting groove 708 are respectively fitted and slidably connected. The second rubber pad 702 or the first rubber pad 602 can increase the friction with the collection tube 9, improve its stability, and also provide a certain degree of protection for the collection tube 9. The front fixing device 6 and the rear fixing device 7 can be accurately fixed and connected to each other by the fitted and slidably connected protruding guide 603 and the limiting groove 708.

[0033] In summary: First, place the two collection pipes 9 into the arcs opposite the front fixing device 6 and the rear fixing device 7, respectively. Then, rotate the fixing shaft 703, which moves the rear fixing device 7 towards the front fixing device 6 until the two collection pipes 9 are fixed. Next, install an appropriate number of first connecting pipes 10 and second connecting pipes 11 as needed. Finally, slowly place the frame 1 into the polluted water. Because the connection between the connecting frame 4 and the connecting shaft 3 is a sliding connection, and the connection position between the connecting frame 4 and the connecting shaft 3 is at the upper end of one side of the connecting frame 4, and a foam board 5 is fixedly connected to the outer surface of the other side of the connecting frame 4, when the frame 1 is placed in the water, the foam board 5 will be able to prevent the foam board from absorbing the foam. The foam board 5 causes the connecting frame 4 to float laterally, allowing for the start of sampling the contaminated water source. After collection, when pulled up, the weight of the counterweight 8 keeps the collection tube 9 vertical, preventing the collected sample from scattering. The connecting frame 4 and connecting shaft 3 are slidably connected, with the connection point on one side of the connecting frame 4. A foam board 5 is fixedly attached to the outer surface of the other side of the connecting frame 4. When the device is submerged in water, the foam board 5 causes the connecting frame 4 to float laterally, facilitating easier sampling of the contaminated water source. Furthermore, when pulled up, the weight of the counterweight 8 ensures the sample remains vertical. The gravity of block 8 will keep the collection tube 9 in a vertical position, preventing the sample collected in the collection tube 9 from scattering. This increases the practicality of the water quality sampling device for environmental pollution detection. The front fixing device 6 and the rear fixing device 7 can more easily fix the symmetrical collection tube 9, allowing simultaneous sampling in one place and preventing the randomness of sample detection, thus improving the efficiency of detection quality and further enhancing the practicality of the water quality sampling device for environmental pollution detection. The through hole 711 and the sliding groove 709 are respectively fitted and slidably connected to the outer surface of the limiting post 605 or the connecting block 606, which can limit the position of the symmetrical rear fixing device 7. The position and movement trajectory, through the position and connection relationship of the second connecting plate 701, sliding baffle 704, spring 706 and fixed baffle 705, can provide a certain buffering effect for the collection tube 9, preventing damage when the collection tube 9 is fixed. The fixed handle 707 facilitates the rotation of the fixed shaft 703. The second rubber pad 702 or the first rubber pad 602 can increase the friction with the collection tube 9, improve its stability, and also provide a certain protection for the collection tube 9. The protruding guide 603 and the limiting groove 708 are respectively fitted and slidably connected, so that the front fixing device 6 and the rear fixing device 7 can be accurately fixed and connected to each other.
