Description

Technical Field

[0001] The present invention relates to the technical field of water pollution sampling, and particularly relates to a sampling device for detection. Background Art

[0002] The problem of water pollution has always been a severe challenge faced globally, which has had a profound impact on the ecological environment, human health, and social and economic development. Accurate water pollution detection is crucial for timely discovering pollution sources, evaluating water quality, and formulating effective treatment measures. The first and most critical step in water pollution detection is to obtain representative water samples, which depends on a sampling device with excellent performance. The present invention is a sampling device for detection.

During the actual sampling process, according to different sampling distance requirements, the hose can be flexibly wound and unwound.

[0027] In addition, in the present invention, by controlling the extension of the second hydraulic rod, since its piston rod is connected to the second sliding plate and the second sliding plate slides on the rail rod, the extension of the second hydraulic rod pushes the second sliding plate to slide leftward. At the same time, one end of the third hydraulic rod is fixed on the first sliding plate and the other end is connected to the second sliding plate. Contracting the third hydraulic rod drives the first sliding plate and related components to move leftward together, so that the water suction end of the hose can be accurately placed inside the water source.

[0060] Embodiment 3, based on Embodiment 1 and Embodiment 2,

[0061] Two groups of water pumps 5 are installed on the partition plate 26 by bolts. Three - phase motors 51 are installed on both groups of water pumps 5 by bolts. An inlet three - way pipe 52 is connected between the inlet ends of the two groups of water pumps 5 by bolts. Control valves are installed at the outlet ends of both groups of water pumps 5. A connecting pipe 53 is connected between the outlet ends of the two groups of water pumps 5. A shunt pipe 54 is connected to the connecting pipe 53. Two filter tanks 55 are connected to the shunt pipe 54. A confluence pipe 56 is connected to the outlet ends of the two filter tanks 55. Control valves are installed on both the shunt pipe 54 and the confluence pipe 56. The inlet three - way pipe 52 is connected to the hose on the hose reel 46. Its functions are as follows: An inlet three - way pipe 52 is connected between the inlet ends of the two groups of water pumps 5 by bolts. The function of the inlet three - way pipe 52 is to aggregate and distribute the water samples from the hose on the hose reel 46. On the one hand, it distributes the water samples inhaled from the hose to the two groups of water pumps 5, realizing the shunt of water samples and improving the efficiency of water sample collection and treatment. On the other hand, when one of the water pumps 5 or related components fails, the other water pump 5 can still draw water samples from the hose through the inlet three - way pipe 52, ensuring the continuity of water sample collection work. The shunt pipe 54 connected to the connecting pipe 53 shunts and conveys the water samples output from the water pumps 5 to the two filter tanks 55, realizing the decentralized treatment of water samples. The main function of the filter tank 55 is to filter the water samples, remove impurities in the water samples, and improve the quality of the water samples to meet the requirements of subsequent detection.

[0062] Working principle of this embodiment: The support structure composed of the support frame 11, welding seat 12, support arm 121 and first hydraulic rod 122 on the load-bearing plate 1 can adjust the angle of the support arm 121 through the telescopic movement of the first hydraulic rod 122 according to different terrain conditions. At the same time, the hinge structure between the anchor 1211 and the support arm 121 enables the device to adapt to uneven ground. By the telescopic movement of the second hydraulic rod 221, the second sliding plate 23 can be pushed to slide along the rail rod 2. The piston rod of the third hydraulic rod 242 on the first sliding plate 24 is fixedly connected to the second sliding plate 23, and they work together to achieve precise control of the position of the second sliding plate 23, enabling the water suction end of the hose to be accurately placed inside the water source. No matter how complex the position of the water source is, accurate positioning and collection can be achieved. The first sliding plate 24 slides smoothly on the rail rod 2 through a linear bearing 241. Components such as the hinge plate 251, threaded block 2511, and knob 2513 on the fixed plates 25 at its left and right ends can further fine-tune the position of the sliding plate. By rotating the knob 2513, the hinge plate 251 is driven to move through screw transmission, thereby adjusting the fit degree between the contact wheel 2512 and the rail rod 2 to ensure the stability and flexibility of the sliding plate movement. By rotating the locking cap 45 to move it axially along the rotating rod 41, the tensioning plate 44 is driven to expand or contract, facilitating the installation and disassembly of the hose winding roller 46. Start the second motor 345, and the power is transmitted to the top roller 342 to make it rotate. The top roller 342 and the bottom roller 311 cooperate to work, and their relative movement can convey and lower the hose placed between them. By adjusting the screw rod 3431, the distance between the top roller 342 and the bottom roller 311 can be adjusted according to the size of the hose and operation requirements. The two groups of water pumps 5 installed on the partition 26 are the power sources for water sample collection, driven by the third motor 51. The water sample is sucked from the hose on the hose winding roller 46 through the inlet three-way pipe 52. The inlet three-way pipe 52 distributes the water sample to the two groups of water pumps 5. The water pumps 5 pump the water sample from the water source, and the control valve at the water outlet end of the water pump 5 can control the water flow. The water is conveyed to the shunt pipe 54 through the connecting pipe 53. The shunt pipe 54 shunts the water sample to the two groups of filter tanks 55. The filter tanks 55 initially filter the water sample to remove impurities. The control valves on the shunt pipe 54 and the confluence pipe 56 can control and adjust the water flow to ensure the effectiveness of the filtering process. The water sample filtered by the filter tanks 55 is collected through the confluence pipe 56 and finally collected in the water sample collection device.
