Technical Field

[0001] The present invention relates to the technical field of water quality sampling equipment, and specifically to an in-situ passive water quality sampling device and method for organic pollutants. Background Art

[0002] Water quality sampling devices are indispensable tools in modern water resource management and environmental monitoring. Their main function is to regularly sample water bodies in order to analyze various water quality indicators, such as pH value, dissolved oxygen, heavy metal content, and organic pollutants. These data are of great significance for evaluating the degree of water body pollution, formulating treatment plans, and ensuring public health.

[0003] Traditional water quality sampling methods are mostly active sampling, that is, water samples are pumped into the sampling container through power equipment such as water pumps. This method has many disadvantages. For example, it requires external power support, the equipment is relatively large in size, the operation is complex, and it is easy to disturb the water samples during the sampling process, affecting the accuracy of the monitoring results. In addition, for some remote areas or waters that are difficult to reach, the deployment and maintenance costs of active sampling equipment are relatively high and it cannot adapt to waters at different depths. Therefore, we propose an in-situ passive water quality sampling device and method for organic pollutants. Summary of the Invention

[0006] The effects achieved by the above components are as follows: By setting the adjusting mechanism, the effect of actively sampling water sources at different depths is achieved. Traditional water quality sampling requires external power support, the equipment is relatively large in size, the operation is complex, and it is easy to disturb the water samples during the sampling process, affecting the accuracy of the monitoring results and at the same time unable to test waters at different depths, improving the practicability of the device.

[0012] The effects achieved by the above components are as follows: Rotating the screw moves within the setting block, and the screw drives the sharp cone to move downward, increasing the stability of the support of the sliding rod and the fixed bin for the sampling main body. Since the underwater soil is soft, a support point is prone to tilting.

[0018] The effects achieved by the above components are as follows: By rotating the threaded rod to drive the T-shaped plate to move up and down while sliding on the arc surface of the fixed rod, the moving path of the T-shaped plate becomes more stable.

[0019] Preferably, a protection mechanism is provided on the surface of the sampling main body. The protection mechanism includes a servo motor fixedly connected to the surface of the sampling main body. The output end of the servo motor is fixedly connected with a mounting disc.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1-8, the present invention provides a technical solution: an in-situ passive water quality sampling device for organic pollutants, including a sampling main body 1. A plurality of water inlets are provided on the arc surface of the sampling main body 1. An adsorption module and a signal transmission component are installed inside the sampling main body 1. An adjustment mechanism 2 is provided on the surface of the sampling main body 1. By setting the adjustment mechanism 2, the effect of actively sampling water sources at different depths is achieved. Traditional water quality sampling requires external power support, and the equipment is large in size, complex in operation, and prone to disturbing the water sample during the sampling process, affecting the accuracy of the monitoring results and unable to test water at different depths, improving the practicability of the device. An auxiliary mechanism 3 is provided on the arc surface of the fixed bin 201. By setting the auxiliary mechanism 3, the stability of the sampling main body 1 in water is achieved, preventing the sampling main body 1 from being driven by the constantly fluctuating water to swing significantly. A protection mechanism 4 is provided on the surface of the sampling main body 1. By setting the protection mechanism 4, the effect of cleaning the obstacles around the sampling main body 1 is achieved, preventing a large amount of floating objects in the water from moving with the water fluctuation and blocking the water inlets of the sampling main body 1.

[0042] Next, specifically describe the specific settings and functions of its adjustment mechanism 2, auxiliary structure 3 and protection structure 4.

[0043] Such as Figure 3 And Figure 4 And Figure 5, the adjusting mechanism 2 includes a fixed bin 201, the fixed bin 201 is fixedly connected to the surface of the sampling main body 1, a slide bar 202 is slidably connected to the inner surface of the fixed bin 201, two connecting plates 203 are fixedly connected to the surface of the fixed bin 201, a lead screw 204 is inserted into the connecting plate 203 by internal threading, one end of the lead screw 204 is rotatably connected to a clamping plate 205, the surface of the clamping plate 205 abuts against the slide bar 202, a limiting rod 206 is slidably inserted into the connecting plate 203, one end of the limiting rod 206 is fixedly connected to the clamping plate 205, rotating the lead screw 204 moves within the connecting plate 203, the lead screw 204 drives the clamping plate 205 to move, and the clamping plate 205 drives the limiting rod 206 to slide within the connecting plate 203, avoiding the situation where the clamping plate 205 rotates as the lead screw 204 rotates, improving the stability of the device. A non-slip pad 207 is fixedly connected to the surface of the clamping plate 205, and the material of the non-slip pad 207 is rubber. By setting the rubber non-slip pad 207, due to the good elasticity and flexibility of the rubber material, it can maintain good anti-slip performance underwater, has a large surface friction, and can effectively prevent slipping. In addition, rubber also has water resistance and corrosion resistance, suitable for a variety of underwater environments. Two setting blocks 208 are fixedly connected to the arc surface of the slide bar 202, a screw 209 is inserted into the setting block 208 by internal threading, one end of the screw 209 is fixedly connected to a sharp cone 210, rotating the screw 209 moves within the setting block 208, and the screw 209 drives the sharp cone 210 to move downward, increasing the stability of the support of the slide bar 202 and the fixed bin 201 on the sampling main body 1. Since the underwater soil is soft, a support point is prone to tilting. The size of the sliding plate is adapted to the size of the inner surface of the fixed bin 201. One end of the screw 209 is fixedly connected to a handle 211, and rotating the handle 211 drives the screw 209 to move within the setting block 208, so as to facilitate the staff to stably rotate the threaded rod 34 to precisely control the position of the sharp cone 210.

[0044] As Figure 6 and Figure 7 , the auxiliary mechanism 3 includes a mounting frame 31, the mounting frame 31 is fixedly connected to the arc surface of the fixed bin 201, several counterweight blocks 32 are slidably connected to the inner surface of the mounting frame 31, the shape of the counterweight block 32 is semi-circular, two connecting frames 33 are fixedly connected to the surface of the mounting frame 31, a threaded rod 34 is rotatably connected to the connecting frame 33, a T-shaped plate 35 is threadedly connected to the arc surface of the threaded rod 34, one side of the T-shaped plate 35 abuts against the counterweight block 32, a fixed rod 36 is fixedly connected to the surface of the connecting frame 33, and the T-shaped plate 35 is slidably connected to the arc surface of the fixed rod 36. By rotating the threaded rod 34 to drive the T-shaped plate 35 to move up and down while sliding on the arc surface of the fixed rod 36, the movement path of the T-shaped plate 35 is more stable.

[0045] As Figure 8 shown, the protection mechanism 4 includes a servo motor 41 fixedly connected to the surface of the sampling main body 1. The output end of the servo motor 41 is fixedly connected with a mounting plate 42. One end of the mounting plate 42 is fixedly connected with a plurality of connecting plates 203. The shape of the connecting plate 203 is wavy. A plurality of drainage holes 45 are formed on the surface of the placement plate 43. A plurality of setting plates 44 are fixedly connected to the surface of the placement plate 43. The floating objects can be blocked in advance by the setting plates 44 and made to move away through collision.

[0046] The method specifically includes the following:

[0047] S1. First, use the adjustment mechanism 2 to lower the slide plate below the sampling main body 1;

[0048] S2. First, use the auxiliary mechanism 3 to install the counterweight 32 in the mounting frame 31;

[0049] S3. First, use the protection mechanism 4 to rotate the setting plate 44 around the sampling main body 1.

[0050] Working principle: When the staff collects water, an adsorption module and a signal transmission component are installed inside the sampling main body 1. The adsorption module is arranged inside the sampling main body 1 and consists of multiple layers of different types of adsorption materials, such as activated carbon fibers, molecularly imprinted polymers, etc. These adsorption materials have specific adsorption capabilities for different types of organic pollutants and can efficiently adsorb and enrich the organic pollutants in the water sample. There are also a sensor and a wireless transmission module. The sensor real-time monitors relevant parameters of the water sample inside the sampling main body 1, such as the concentration of organic pollutants, temperature, pH value, etc., and sends the data to the remote monitoring center through the wireless transmission module, facilitating the staff to grasp the sampling situation in real time. According to the water depth and sampling requirements, the height of the sampling main body 1 is adjusted. First, the sliding rod 202 is pulled to slide inside the height bin. The sliding rod 202 drives the setting block 208 to move. When the sliding rod 202 is adjusted to an appropriate position, the lead screw 204 moves inside the connecting plate 203. The lead screw 204 drives the clamping plate 205 to move. The clamping plate 205 drives the anti-slip pad 207 to move until the anti-slip pad 207 abuts against the sliding rod 202. By setting the anti-slip pad 207 made of rubber, due to the good elasticity and flexibility of the rubber material, it can maintain good anti-slip performance underwater. Its surface has a large frictional force, which can effectively prevent slipping. In addition, rubber also has water resistance and corrosion resistance and is suitable for a variety of underwater environments. Subsequently, the handle 211 is rotated to drive the screw 209 to move inside the setting block 208. The setting block 208 drives the sharp cone 210 to move. The screw 209 rotates and moves inside the setting block 208, and the screw 209 drives the sharp cone 210 to move downward, increasing the stability of the support of the sliding rod 202 and the fixed bin 201 for the sampling main body 1. Since the underwater soil is soft, a single support point is prone to tilting.

[0051] When the staff needs to add counterweight to the fixed bin 201, the semi-circular counterweight block 32 is placed inside the installation. Subsequently, by rotating the threaded rod 34, the T-shaped plate 35 moves downward while sliding on the arc surface of the fixed rod 36, making the movement path of the T-shaped plate 35 more stable until one side of the T-shaped plate 35 abuts against the counterweight block 32, achieving the stability of the sampling main body 1 in the water and preventing the continuously fluctuating water from driving the sampling main body 1 to shake significantly.

[0052] When the staff needs to clean the obstacles around the sampling main body 1, since there are a large number of floating objects in the water and they will move with the flow of the water, the servo motor 41 is started to drive the installation disk 42 to rotate. The installation disk 42 drives the connecting plate 203 to rotate. The connecting plate 203 drives the follower plate to rotate, achieving the effect of cleaning the obstacles around the sampling main body 1 and preventing a large number of floating objects in the water from moving with the water fluctuations and blocking the water inlet of the sampling main body 1.

[0053] This method; when collecting water quality, first use the adjustment mechanism 2 to lower the slide plate below the sampling main body 1; then use the auxiliary mechanism 3 to install the counterweight 32 in the mounting bracket 31; finally use the protection mechanism 4 to rotate the setting plate 44 around the sampling main body 1.
