[0002] Water resources are extremely precious, so it is necessary to monitor and treat water resources well. Environmental protection workers often need to sample and detect lake water.

[0003] At present, the depths of most urban lakes are one to five meters. Existing sampling devices can only use sampling devices corresponding to the depths of the lakes. This is not only more troublesome, but also requires purchasing different models of sampling devices. Moreover, when the existing sampling devices sample water sources at different depths, the water sources at higher levels are likely to enter the sampling device together with the water sources at lower levels, resulting in inaccurate subsequent detection of the water sources.

[0004] Therefore, a water pollution treatment sampling device is needed to solve the problems in the prior art that it is inconvenient to sample water sources at different depths simultaneously and the water sources at higher levels are likely to be mixed with the water sources at lower levels.

[0010] Further, it should be noted that the connecting mechanism includes an installation groove, which is opened on the inner wall of the rubber sealing plug. The installation groove communicates with the through hole at the center of the rubber sealing plug. An extrusion spring is fixed on the inner wall of the installation groove, and the other end of the extrusion spring is fixed with an installation block, and the other end of the installation block is fixed with a clamping head.

Specific embodiments

[0022] The following further describes the present utility model in conjunction with embodiments.

[0023] Please refer to Figures 1-4 , the present utility model provides a water pollution treatment sampling device, including a sampling tube 1. A plurality of water inlets 2 are opened in the middle of the outer wall of the sampling tube 1. A pulling rod 3 is slidably installed on the inner wall of the sampling tube 1. A rubber sealing plug 4 is fixed to the bottom end of the pulling rod 3. A rotating mounting plate 5 is rotatably installed at the bottom end of the rubber sealing plug 4. Four connecting pieces 6 are fixedly distributed at the bottom end of the rotating mounting plate 5. A sealing mechanism 7 is arranged on the inner wall of the connecting piece 6;

[0024] An arc-shaped clamping groove 12 is arranged at the top end of the pulling rod 3. A through hole is opened at the center of the inner wall of the rubber sealing plug 4. A connecting mechanism 11 is arranged on one side inner wall of the rubber sealing plug 4.

[0025] Through the action of the sealing mechanism 7, when it is necessary to sample water at different depths, in order to avoid the mixing of water sources at different depths into the inner wall of the sampling tube 1, the sampling tube 1 can be sealed through the sealing mechanism 7, and at the same time, it is opened during the sampling process, so as to realize the sampling of water at different depths and avoid the mixing of water at different depths into the inner wall of the sampling tube 1.

[0026] The connecting mechanism 11 can mainly realize the quick connection of the sampling tube 1. At the same time, the length of each sampling tube 1 is one meter, so as to realize the accurate sampling of water sources at different depths of the lake surface and can also sample simultaneously, thereby improving the sampling effect of the water source.

[0027] Furthermore, as Figure 2 , Figure 3 shown, it is specifically noted that the sealing mechanism 7 includes a plurality of stress springs 71. The plurality of stress springs 71 are respectively fixed to the bottom of the inner wall of the corresponding connecting piece 6. The other end of the stress spring 71 is fixed with a movable block 72. The other end of the movable block 72 is fixed with a rubber part 73.

[0028] When the sampling tube 1 does not sample the water source, the rubber sealing plug 4 is attached to the water inlet 2, so as to achieve sealing. When sampling the water source, by pulling the pulling rod 3, the rubber sealing plug 4 can be driven to move, so that the sampling tube 1 can be unsealed. Then, as the rubber sealing plug 4 moves upward, due to air pressure, the water source can be sucked into the inner wall of the sampling tube 1. When the rubber sealing plug 4 moves to a certain extent, the sealing mechanism 7 can just seal the water inlet 2, so that the sampling tube 1 can be sealed again.

[0029] Further, as shown in Figure 1 , Figure 2 , Figure 3 , it is specifically noted that wire grooves 8 are arranged at the bottom end of the inner wall of the sampling tube 1 in a four-corner distribution. The rubber parts 73 are attached to the corresponding wire grooves 8, and the rubber parts 73 are engaged with the corresponding pulling rods 3 through movement.

[0030] This solution has the following working process: When it is necessary to sample water sources at different depths, the sealing cap 10 at the bottom of the sampling tube 1 is rotated and unscrewed. Then, another pull rod 3 is aligned and extended through the bottom through-hole of the rubber sealing plug 4. Since both the top of the rubber sealing plug 4 and the end in contact with the chuck 114 are arc-shaped, when the pull rod 3 is under force, it can squeeze the chuck 114, causing it to move to the inner wall of the installation groove 111. At the same time, as the pull rod 3 continues to move, one end of its arc-shaped bayonet 12 corresponds to one end of the chuck 114. Then, under the force of the compression spring 112, the installation block 113 and the chuck 114 can be driven to reset. Thus, the chuck 114 can be engaged with the inner wall of the arc-shaped bayonet 12, enabling multiple sampling tubes 1 to be quickly connected. At the same time, the length of each sampling tube 1 is one meter, which can accurately extract water sources at different depths. When the sampling tube 1 is not extracting water, the rubber sealing plug 4 can seal the water inlet 2. When the pull rod 3 is pulled, it can drive the rubber sealing plug 4 to move, thereby driving the rotating mounting disc 5 and the connecting piece 6 to move. When the rubber sealing plug 4 moves, due to the air pressure inside the sampling tube 1 and outside the water source, water can be extracted from the water inlet 2 into the sampling tube 1. When the rubber sealing plug 4 moves to the top inner wall of the sampling tube 1, multiple sealing mechanisms 7 move to the sides corresponding to the respective water inlets 2. Then, under the force of the force spring 71, the movable block 72 can be driven to reset, further driving the rubber part 73 to move under force. Thus, the water inlet 2 can be sealed by the rubber part 73. Then, the sampling tube 1 is taken out of the water source. At the same time, the sampling tube 1 can also be sealed by the sealing mechanism 7, preventing water sources at different depths from entering the inner wall of the sampling tube 1 and resulting in poor water source detection.

[0031] According to the above working process, it can be seen that by connecting multiple sampling tubes 1, water sources at different depths can be accurately extracted, thereby improving the detection effect of the water source. And the sealing mechanism 7 mainly seals the sampling tube 1, enabling the sampling tube 1 to be sealed before and after water extraction, thus preventing water sources at different depths from mixing into the corresponding sampling tube 1.

[0032] Furthermore, as shown in Figure 2 、 Figure 3 and Figure 4As shown, it is worth specifically stating that the connecting mechanism 11 includes an installation groove 111. The installation groove 111 is formed in the inner wall of the rubber seal 4. The installation groove 111 communicates with the through hole at the center of the rubber seal 4. A compression spring 112 is fixed to the inner wall of the installation groove 111. The other end of the compression spring 112 is fixed with an installation block 113. The other end of the installation block 113 is fixed with a clamping head 114.

[0033] Further, as Figure 4 shown, it is worth specifically stating that the clamping head 114 is engaged with the arc-shaped bayonet 12, and one side of the arc-shaped bayonet 12 is an arc-shaped slope.

[0034] Since the arc-shaped bayonet 12 has an arc-shaped slope, the upper pull rod 3 can be rotated, so as to drive the rubber seal 4 and the connecting mechanism 11 as a whole to rotate. At the same time, one side of the arc-shaped bayonet 12 has a slope extending outward. When the clamping head 114 rotates, it can pass through the slope of the arc-shaped bayonet 12, so as to drive the clamping head 114 to be squeezed, and the clamping head 114 moves to the inner wall of the installation groove 111, thus the connection state between the two sampling tubes 1 can be released.

[0035] Further, as Figure 1 、 Figure 2 、 Figure 3 shown, it is worth specifically stating that openings 9 are formed at the center of the bottom of the sampling tubes 1, and sealing caps 10 are threadedly connected to the inner walls of the openings 9.

[0036] Further, as Figure 1 、 Figure 2 、 Figure 3 shown, it is worth specifically stating that the sampling tube 1 is one meter long. The pull rod 3 passes through the opening 9 and extends to the through hole at the center of the rubber seal 4. Rubber sealing sleeves 13 are sleeved at the connection points between the multiple sampling tubes 1.

[0037] Since the sampling tube 1 is one meter long, and the depth of most lakes in our country is three to five meters, through the connecting mechanism 11, multiple sampling tubes 1 can be connected, so as to accurately sample water sources at different depths simultaneously.

[0038] In summary: Through the action of the sealing mechanism 7, when sampling water at different depths, in order to avoid the mixing of water sources at different depths into the inner wall of the sampling pipe 1, the sealing mechanism 7 can seal the sampling pipe 1 and open it during the sampling process, so as to achieve the sampling of water at different depths while avoiding the mixing of water at different depths into the inner wall of the sampling pipe 1. By connecting multiple sampling pipes 1, the precise extraction of water sources at different depths can be achieved, thereby improving the detection effect of water sources. And through the sealing mechanism 7, the sampling pipe 1 can be mainly sealed, so that the sampling pipe 1 can be sealed before and after the extraction of water sources, thereby avoiding the mixing of water sources at different depths into the corresponding sampling pipe 1.
