[0009] As a further embodiment of this utility model, a refrigerator is provided at the bottom of the sampling device body, and the placement frame is slidably connected to the inside of the refrigerator. The bottom of the refrigerator is fixedly connected with four sets of universal wheels in a rectangular array, which facilitates movement.

[0010] As a further embodiment of this utility model, four sets of positioning bolts are fixedly connected to the top of the sealing strip, and the inner top wall of the refrigerator is provided with slots that are compatible with the positioning bolts.

[0014] (III) Beneficial Effects

[0015] This utility model provides a water quality analysis and sampling device for environmental protection testing, which has the following beneficial effects:

[0016] 1. This environmental protection testing water quality analysis sampling device, through the setting of a sliding component and a fixed sleeve, allows the connecting joint to drive the sliding sleeve to slide inside the fixed sleeve when personnel pull the water sampling pipe. This causes the telescopic spring on the sliding sleeve to be pushed by the limiting block, resulting in compression deformation and elastic force. This force then pushes the limiting block in the opposite direction, thus offsetting part of the pulling impact. This prevents excessive pulling force during use, which could lead to the water sampling pipe detaching or breaking at the joint, thereby improving the safety of the environmental protection testing water quality analysis sampling device.

[0017] 2. This environmental protection testing water quality analysis sampling device, through the setting of support components and sealing frame, allows for the removal of the placement frame when the pressing rod is pressed down. This causes the pressing rod to drive the fixing plate and sealing frame, and the support spring to deform under force, generating elastic force. Consequently, the sealing frame slides down on the top of the placement frame, causing the positioning pin on the sealing strip to disengage from the top insertion hole, thus allowing the placement frame to be removed. Simultaneously, when the placement frame slides back in, the support spring pushes the fixing plate, causing the fixing plate to drive the sealing frame and sealing strip, making the sealing strip tightly adhere to the inside of the refrigerator. This achieves the effect of increasing the airtightness of the refrigerator. Through dynamic sealing, it avoids energy loss caused by poor sealing of the refrigerator and improves the airtightness of the environmental protection testing water quality analysis sampling device.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: an environmental protection testing water quality analysis sampling device, including a connecting pipe 1 and a placement frame 2. One end of the connecting pipe 1 is connected to a fixed sleeve 3. A sliding component 4 is slidably connected inside the fixed sleeve 3. The sliding component 4 and the fixed sleeve 3 are designed to offset part of the pulling impact force, preventing excessive pulling force on the water sampling pipe 18 during use, which could cause the water sampling pipe 18 to fall off or break at the interface, thus improving the safety of the environmental protection testing water quality analysis sampling device. A sealing frame 5 is slidably connected to the top of the placement frame 2, and a sealing strip 6 is fixedly connected to the top of the sealing frame 5. Support assemblies are fixedly connected to both sides of the sealing frame 5. Component 7, through the setting of support component 7 and sealing frame 5, achieves the effect of increasing the sealing performance of refrigerator 10. Through dynamic sealing, it avoids energy loss caused by poor sealing of refrigerator 10 and improves the sealing performance of environmental protection testing water quality analysis sampling device. Sliding component 4 includes sliding sleeve 401 slidably connected inside fixed sleeve 3. Telescopic spring 402 is sleeved on the surface of sliding sleeve 401. Two sets of limit blocks 403 are fixedly connected to the surface of sliding sleeve 401. Support component 7 includes fixed plate 701 fixedly connected to both sides of sealing frame 5. Positioning rod 702 is slidably connected to both ends of fixed plate 701. Supporting spring 703 is sleeved on the surface of positioning rod 702.

[0025] The other end of the connecting pipe 1 is connected to a peristaltic pump 8, and a sampling device body 9 is fixedly connected to one side of the peristaltic pump 8. The sampling device body 9 facilitates sampling and detection.

[0026] The bottom of the sampling device body 9 is equipped with a refrigerator 10. The placement frame 2 is slidably connected to the inside of the refrigerator 10. The bottom of the refrigerator 10 is fixedly connected with four sets of universal wheels 11 in a rectangular array. The universal wheels 11 facilitate movement.

[0027] Four sets of positioning bolts 12 are fixedly connected to the top of the sealing strip 6. The inner top wall of the refrigerator 10 is provided with slots that are compatible with the positioning bolts 12. The slots facilitate the insertion and positioning of the positioning bolts 12.

[0028] One side of one set of fixing plates 701 is fixedly connected to a pressing rod 13, and a support shell 14 is slidably connected to the surface of the pressing rod 13. The support shell 14 is fixedly connected to one side of the placement frame 2. The setting of the support shell 14 facilitates the sliding of the pressing rod 13.

[0029] The placement frame 2 has several sets of collection bottles 15 inside. The top of the placement frame 2 has a sliding groove that matches the sealing frame 5. The sliding groove facilitates the sliding of the sealing frame 5.

[0030] The sliding sleeve 401 has an internal threaded connection to a connecting joint 16. Both the sliding sleeve 401 and the connecting joint 16 are fitted with sealing rings 17. One end of the connecting joint 16 is connected to a water sampling pipe 18. The water sampling pipe 18 facilitates the collection of liquid samples.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When personnel pull the water pipe 18, the connecting joint 16 drives the sliding sleeve 401 to slide inside the fixed sleeve 3. Then, the telescopic spring 402 on the sliding sleeve 401 is pushed by the limiting block 403, causing the telescopic spring 402 to deform under pressure and generate elastic force, which in turn pushes the limiting block 403 in the opposite direction.

[0033] Second step: When it is necessary to remove the placement frame 2, press down the pressing rod 13, so that the pressing rod 13 drives the fixing plate 701 and the sealing frame 5, the support spring 703 is deformed by force to generate elastic force, and then the sealing frame 5 slides down on the top of the placement frame 2.

[0034] The third step: the positioning bolt 12 on the sealing strip 6 is disengaged from the top insertion hole, and the placement frame 2 is pulled out. At the same time, when it slides back into the placement frame 2, the support spring 703 pushes the fixing plate 701, so that the fixing plate 701 moves the sealing frame 5 and the sealing strip 6, so that the sealing strip 6 is tightly attached to the inside of the refrigerator 10.
