Description

Technical Field

[0001] The invention belongs to the field of detection technology, and in particular relates to an automatic time-series sampling device for detecting pollution in a waterfront plant area. Background Art

[0002] In recent years, the country has attached increasing importance to environmental protection, and the supervision and inspection of key polluting enterprises have gradually been incorporated into daily supervision.

[0003] At present, the pollution in some factory areas of some enterprises mainly includes sediment pollution and water pollution. Since the sediment is constant, its pollution detection method mainly adopts sediment collection or direct on-site analysis, or laboratory analysis, which can effectively investigate the sediment pollution at a specified time. However, water samples have periodic fluidity, and have the characteristics of rapid short-term changes on a time scale compared to the sediment. Especially in the groundwater environment affected by tides, its fluidity has a greater impact on the time scale. Therefore, for groundwater affected by tides, sampling and investigation of water samples at a specified time may result in the omission of key information, resulting in the problem of missing regulatory information, causing polluting enterprises to avoid inspection according to tidal laws.

[0004] In response to the above problems, one of the main detection methods in the prior art is to set up manpower to frequently sample groundwater, but this will not only increase unnecessary labor costs, but also be affected by human factors, resulting in sampling results that are not necessarily accurate; another method is monitoring station detection, which is to dig wells near the coastal factory area and install groundwater automatic monitoring stations, so as to fully automate the real-time online detection of pollution conditions, which solves the above problems to a certain extent. However, in the delta area and the coastal area at the junction of the river and the sea, due to the presence of a large amount of terrigenous particulate matter in the groundwater, it has a strong sedimentation effect, and the pollutants are also granular or attached to granular sediment, which causes the pollutants to quickly settle to the bottom and are not collected and analyzed by the suction system, resulting in inaccurate pollutant detection quantity and / or category results. Although the above technical solution can complete the sampling of the sediment layer by setting up a high-suction bottom suction system, this design will significantly change the morphology of the sediment layer, resulting in subsequent collection results that are no longer accurate.

[0005] In summary, there is a need to improve the existing water sampling device so that it can effectively obtain water sample characteristics over a wide area and time at a low cost, providing a more convenient and accurate way for pollution supervision in the factory area.

[0041] It should also be noted that the methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0042] The present invention provides a Figure 1The automatic time-series sampling device for detecting pollution in waterfront factory areas shown is installed in a delta area or a nearshore area at the junction of a river and the sea. Among them, the device mainly includes a lifting water intake device and a lateral conveying device. The lifting water intake device is located in a groundwater well and is installed on the side wall of the groundwater well through a fixed pile 1. Preferably, the main body of the lifting water intake device of this embodiment is a vertically arranged first crawler machine 2, and the upper and lower pulleys are rotatably connected to the corresponding fixed piles 1 and are bridged with a crawler. Along the movement direction of the crawler of the first crawler machine 2, a rotating shaft is installed on several connecting sections at equal intervals, and each rotating shaft is rotatably connected to a water extractor 3.

[0043] The lifting water intake device is set across the groundwater level line, and the upper part and the horizontal conveying device are exposed above the water surface. The lower part of the lifting water intake device is located below the water surface and contacts the sediment layer at the extreme position of the movement of the lower end of the water intake device 3.

[0044] Preferably, the upper part of the water extractor 3 of this embodiment is a box structure, which is rotatably connected to the rotating shaft through a hoisting structure, and an electric-controlled grab is provided at its lower part. When sampling is required, it is controlled to close near the bottoming position, so that the water sample and a small amount of sediment are sealed into the water extractor 3. In another embodiment, a sampling port can be designed at the lower part of the water extractor 3, and a normally open one-way valve controlled by an elastic reset member can be installed. When the bottom is touched, a small amount of sediment is lifted up and enters the water extractor 3 with the water sample, and is sealed into the water extractor 3 as the one-way valve is closed during the lifting process, completing the sampling and reducing the damage to the morphology of the sediment layer. Further, the water extractor 3 of this embodiment is also provided with a flip mechanism, which includes a first magnetic component and a second magnetic component. The first magnetic component is installed on the side of each water dispenser 3, and the first magnetic component is one of a permanent magnet, an electromagnet or a ferromagnetic material. In this embodiment, the water dispenser 3 is selected to be made of ferromagnetic material, and the water dispenser 3 as a whole is the first magnetic component, and then the second magnetic component 4 is fixedly installed on the side of the lifting water intake device through a support frame, and the second magnetic component 4 is an electromagnet. When each water dispenser 3 passes through the magnetic influence range of the second magnetic component 4, it is regarded as its sample outlet position. At the same time, in this embodiment, the water dispenser 3 correspondingly runs to the upper limit position. The sample outlet 11 is in the shape of a long tube, with a part extending forward and tilted downward at a certain angle. It is specifically installed on the side of the water dispenser 3 and close to the middle. When the water dispenser 3 is at the sample outlet position, there is a water storage tank 7 correspondingly passing below the sample outlet 11.

[0045] In the above content, although the end of the lateral conveying device can be designed to be below the water extractor 3, and the sample can be released by the electric-controlled grab bucket, the design of the sample outlet 11 takes into account the need for spatial dimension planning of the lifting water extraction device and the lateral conveying device to avoid occupying too much underground space, thereby reducing the radial dimension requirements of the groundwater well. Therefore, the lifting water extraction device and the lateral conveying device are staggered at a certain distance, thereby reducing the lateral dimension of the lifting water extraction device, and relying on the extended sample outlet 11 to accurately drop the water sample and sediment into the water storage tank 7. Specifically, as the first crawler machine 2 rotates, the water extractor 3 can make reciprocating up and down movements, and continuously enter the water for sampling operations; when the water extractor 3 passes through the second magnetic component 4, it is affected by the suction force and flips around its rotating axis, so that the water sample and sediment in the water extractor 3 flow out along the sample outlet 11 and fall into the water storage tank 7 below. In another aforementioned embodiment, as the water extractor 3 flips over and part of the sample flows out, the normally open one-way valve opens, and the magnetic force weakens as the distance increases. After the water extractor 3 is straightened, the remaining residual sample can fall into the water tank 7 or the well from the sampling port designed near the front.

[0046] The end of the transverse conveying device is connected to a warehouse; preferably, the main body of the transverse conveying device is a second crawler machine 6 arranged horizontally, wherein the crawler of the second crawler machine 6 is arranged vertically and rotates along the horizontal plane, and a plurality of water tanks 7 are evenly distributed along the direction of movement, and the water tank 7 is detachably connected to the crawler piece or the connecting section at the corresponding position. Specifically, in this embodiment, the detachable connection can be achieved by an inverted hook and a lock. The transverse conveying device also includes a conveying table, which serves as a supporting structure for the water tank 7. Its main body is designed to be an annular structure (long waist shape when viewed from above) and is mounted on the outside of the second crawler machine 6. The surface of the conveying table is relatively smooth, and the water tank 7 is in sliding contact with the conveying table. A box drop port is processed at the far end of the conveying table, and an induction door 9 flush with the table is installed. It detects whether the water tank 7 stores sufficient samples through a pressure sensor. When the requirements are met, the induction door 9 flips down, and the water tank 7 falls into the gravity slide 10 connected below the induction door 9, and finally slides to the warehouse at the end of the slide. The warehouse of this embodiment is an automated stereoscopic warehouse, and the water tank 7 is stored in the corresponding position of the sample rack according to the preset information. Furthermore, due to the need for long-term sealing operation, the water tank 7 is a self-closing water tank; further, an opening and closing sealing cover is designed on the upper part of the water tank 7, which is provided with a magnetic suction device and coated with magnetic material on the conveying table. When the water tank 7 falls into the gravity slide 10, the magnetic force weakens, and the sealing cover seals the water tank 7; in another embodiment, an elastic reset part can also be installed at the rotating shaft of the sealing cover, so that as the sample falls from the water extractor 3 to the sealing cover, it is turned over and opened, and then automatically rebounds and seals.

[0047] In this embodiment, a single sampling operation can be prepared in advance by personnel mounting a water tank 7 on the second crawler machine 6; preferably, in order to realize an automated design, a box delivery device can be arranged laterally on the transverse conveying device, specifically an empty box conveyor conventionally configured in the production line, thereby realizing the ability to automatically replenish boxes.

[0048] Preferably, in order to reduce costs, the power motor 8 of the second crawler machine 6 is connected to the pulley of the first crawler machine 2 through the transmission shaft and the gear transmission mechanism 5 to drive it to rotate. The advantage of this design is that it reduces the construction cost and not only reduces the number of power units; at the same time, by adjusting the transmission mechanism, when the water extractor 3 runs to the top, a water storage tank 7 just passes below, achieving a linkage effect, and also reducing complex control systems and sensor accessories.

[0049] Preferably, the device also includes a flow meter, and technicians can install the flow meter in the groundwater well, or at the bottom of the lifting water intake device, or on the side of each water intake device 3 according to needs to detect the flow rate of water in the well.

[0050] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
