[0022] As Figures 1-6As shown in the figure, a water sample preservation device for wastewater detection includes a sampling bottle 100 and a storage box. A rubber stopper 101 is provided at the mouth of the sampling bottle 100. An insertion hole is provided on the rubber stopper 101. When the sampling bottle 100 is inverted with liquid inside, no liquid will leak out from the insertion hole. Because the rubber stopper 101 has a certain elasticity, when there is no hard insertion tube 301 in the insertion hole, the rubber in the insertion hole will bounce into the insertion hole and block the insertion hole. Therefore, when the sampling bottle 100 is inverted, the sample will not flow out from the insertion hole. The storage box 200 includes a box cover and a box body. The box cover is arranged on the box body and cooperates with the box body. A plurality of placement grooves are arranged inside the box body. A sample storage bottle 300 is arranged in the placement groove. A hard insertion tube 301 is fixed on the bottle cap of the sample storage bottle 300. The hard insertion tube 301 communicates with the sample storage bottle 300 and cooperates with the insertion hole. The sample storage bottle 300 is clamped by a clamping mechanism 400 arranged inside the storage box 200. During use, first remove the rubber stopper 101 of the sampling bottle 100. After sampling is completed, insert the rubber stopper 101 into the mouth of the sampling bottle 100. Move the sampling bottle 100 to align the insertion hole of the rubber stopper 101 of the sampling bottle 100 with the insertion tube of the sample storage bottle 300, and insert the insertion tube into the rubber stopper 101 to communicate with the sampling bottle 100. The wastewater sample in the sampling bottle 100 flows into the sample storage bottle 300 under the action of gravity;

[0023] Specifically, the clamping mechanism 400 includes a fixed clamping head, a movable clamping head 401, a mounting plate 402, an inclined surface slider 403, a guide rod 404, a spring 405, an inclined surface pressing block 406, and a limiting component 407. The fixed clamping head is fixed on one side inside the placement groove, the movable clamping head 401 is arranged on the opposite side of the fixed clamping head, the movable clamping head 401 is fixed on the mounting plate 402, and a guide rod 404 is also fixed on the mounting plate 402. The mounting plate 402 is slidably arranged. When setting a sliding track or groove for the mounting plate 402, the track or groove ends when the movable clamping head 401 has clamped the sample storage bottle 300, or a limiting member is provided for the mounting plate 402 to prevent it from continuing to slide forward when the sample storage bottle 300 is clamped. A spring 405 is sleeved on the guide rod 404, and the guide rod 404 passes through the inclined surface slider 403 through a through hole provided on the inclined surface slider 403. The inclined surface slider 403 is slidably arranged left and right inside the box body. A first inclined surface 4031 is provided on the inclined surface slider 403, and the inclined surface pressing block 406 is slidably arranged up and down inside the box body. A second inclined surface 4061 is provided on the inclined surface pressing block 406. The first inclined surface 4031 cooperates with the second inclined surface 4061. The limiting component 407 is used to limit the displacement of the inclined surface pressing block 406. When placing the sample storage bottle 300 in the placement groove, one side of the sample storage bottle 300 abuts against the fixed clamping head. After placing all the sample storage bottles 300 in the same placement groove, the worker presses down the inclined surface pressing block 406. The inclined surface pressing block 406 slides downward, the second inclined surface 4061 contacts the first inclined surface 4031, and the inclined surface pressing block 406 continues to push the inclined surface slider 403 forward to slide, compressing the spring 405. After the spring 405 is compressed to a certain amount, the mounting plate 402 drives the movable clamping head 401 to move forward. When the top of the inclined surface pressing block 406 is flush with the upper surface of the box body, it is regarded as clamping the sample storage bottle 300. Then, the worker operates the limiting component 407 to limit the upward movement of the inclined surface pressing block 406;

[0024] Specifically, the limiting component 407 includes a rotating piece 4071, a fixed piece 4072 and a limiting bolt 4073. The rotating piece 4071 is rotatably arranged on the box body on one side of the placement groove. One end of the fixed piece 4072 is fixed on the box body on the other side of the placement groove. The fixed piece 4072 is provided with a first through hole 40721, and the rotating piece 4071 is provided with a second through hole 40711. The limiting bolt 4073 passes through the first through hole 40721 and the second through hole 40711 and is threaded into the threaded hole on the box body to fix the rotating piece 4071. During use, to ensure the limiting effect, several groups of limiting components 407 can be set. After the staff presses down the inclined surface pressing block 406 completely, one hand holds the inclined surface pressing block 406, and the other hand operates the rotating piece 4071. Rotate the unfixed side of the rotating piece 4071 from the unfixed side of the fixed piece 4072 to the lower side of the fixed piece 4072, align the first through hole 40721 and the second through hole 40711, and tighten the limiting bolt 4073 to achieve the limit;

[0025] Preferably, a rotating handle 4074 is provided at the head of the limiting bolt, which is convenient for the staff to operate;

[0026] Specifically, the box body and the box cover are connected by a buckle 500. A rubber pressing strip 2011 is provided on the inner top surface of the box cover. The position of the rubber pressing strip 2011 is adapted to the position of the intubation tube after the box cover is closed, and the rubber pressing strip 2011 is provided to prevent the liquid in the sample storage bottle 300 from leaking from the rigid intubation tube 301;

[0027] Preferably, an installation groove is provided on the box body, and an installation rib 2012 is provided on the box cover. The installation rib 2012 is inserted into the installation groove when the box cover and the box body are closed, making the connection between the box cover and the box body more reliable;

An air outlet is also provided on the bottle cap of the sample storage bottle 300, and a soft plug 302 adapted to it is provided at the air outlet. Close the valve 104 when sampling the sampling bottle 100. When transferring the wastewater sample, open the valve 104 of the sampling bottle 100 and pull out the soft plug 302 at the air outlet of the sample storage bottle 300 to prevent the transfer of the wastewater sample from slowing down or stopping due to the change of air pressure in the sampling bottle 100 during the transfer process;

[0029] Preferably, a sample storage bottle bottom support is provided in the placement groove. The sample storage bottle bottom support is provided with a support groove, and the shape of the support groove matches the shape of the bottom of the sample storage bottle 300. The shaped sample storage bottle bottom support makes the placement of the sample storage bottle 300 more stable.

[0030] Working principle: When in use, open the buckle 500 and remove the box cover. First, place the empty sample storage bottle 300 into the placement groove, so that the bottom of the sample storage bottle 300 is placed into the bottom support of the sample storage bottle. One side of the sample storage bottle 300 abuts against the fixed clamping head. After all the sample storage bottles 300 in the same placement groove are placed, the staff presses down the inclined surface pressing block 406. The inclined surface pressing block 406 slides downward. The second inclined surface 4061 contacts the first inclined surface 4031. The inclined surface pressing block 406 continues to push the inclined surface slider 403 forward to slide, compressing the spring 405. After the spring 405 is compressed to a certain amount, the mounting plate 402 drives the moving clamping head 401 to move forward. When the top of the inclined surface pressing block 406 is flush with the upper surface of the box body, then the staff holds the inclined surface pressing block 406 with one hand and operates the rotating piece 4071 with the other hand. Turn the unfixed side of the rotating piece 4071 from the unfixed side of the fixed piece 4072 to the lower side of the fixed piece 4072, align the first through hole 40721 and the second through hole 40711, and tighten the limit bolt 4073 to achieve limiting. This operation can also be completed by two people. Then, pull out the rubber stopper 101 of the sampling bottle 100, close the valve 104 of the sampling bottle 100. After sampling is completed, insert the rubber stopper 101 into the bottle mouth of the sampling bottle 100, then open the valve 104 of the sampling bottle 100, pull out the soft stopper 302 of the sample storage bottle 300, move the sampling bottle 100, align the insertion hole of the rubber stopper 101 of the sampling bottle 100 with the insertion tube of the sample storage bottle 300, insert the insertion tube into the rubber stopper 101 to communicate with the sampling bottle 100. The waste water sample in the sampling bottle 100 flows into the sample storage bottle 300 under the action of gravity. After the amount of the waste water sample in the sample storage bottle 300 reaches the requirement, pull out the sampling bottle 100, insert the soft stopper 302 into the air outlet. If multiple sample storage bottles 300 are needed to store the same sample, perform this operation multiple times. Finally, align the mounting rib 2012 on the box cover with the mounting groove on the box body and close it. At this time, the rubber pressing strip 2011 on the box cover corresponds to the position of the hard insertion tube 301, and snap on the buckle 500.
