Background
Water pollution is water pollution caused by the reduction or loss of the use value of water caused by harmful chemical substances. Acid, alkali, oxidant in sewage, compounds such as copper, cadmium, mercury, arsenic and the like, and organic poisons such as benzene, dichloroethane, ethylene glycol and the like can poison aquatic organisms, and influence drinking water sources and scenic spot landscapes. The organic matters in the sewage consume oxygen in the water when being decomposed by microorganisms, so that the life of aquatic organisms is influenced, after dissolved oxygen in the water is exhausted, the organic matters are anaerobically decomposed to generate unpleasant gases such as hydrogen sulfide, mercaptan and the like, so that the water quality is further deteriorated, and therefore, a sampling system for water pollution treatment is needed to be used for sampling the water area regularly, and the subsequent detection work is convenient.

As still further aspects of the invention: positioning bolts are arranged at four corners of the top of the base, and the ends of the positioning bolts penetrate through the base.
The invention also discloses a sampling method for water pollution treatment, which adopts the sampling system for water pollution treatment and comprises the following steps:
s1, firstly, carrying a base to the side of a water area to be sampled, then, rotating a positioning bolt until the positioning bolt is screwed into a soil layer beside the water area, stably positioning the base, enabling a mounting frame to be positioned right above the water area, and then controlling a driving motor to be started to enable a limiting shaft to rotate, enabling a rope to be lengthened on the limiting shaft, and immersing the sampling frame into water;
s1.1, it is to be noted that after the sampling frame is immersed in water, the first slide plate is propped against the water inlet at the moment, the second slide plate is positioned in the middle of the exhaust cavity, water in the water area enters the exhaust cavity through the water outlet at the moment, and although air exists in the sliding cavity, the L-shaped cavity, the water taking cavity and the left half part of the exhaust cavity, the weight of the inner structure of the sampling frame and the water mass of the right half part of the exhaust cavity are greater than the buoyancy of the sampling frame, so that the sampling frame can sink downwards in the water;
s1.2, in addition, the rope can drive the limiting wheel to rotate in the process of lengthening the rope in the mounting frame, at the moment, the rope does not need to be in friction contact with the sliding port, and the sliding friction between the rope and the sliding port is changed into rolling friction, so that the service life of the rope is prolonged, the friction force is reduced, and electric energy is saved for the driving motor;
s2, when the sampling frame sinks to a proper depth, the driving motor is started at the moment, the first screw rod is rotated, the first nut drives the first pushing piece to pull the first sliding plate to move upwards in the sliding cavity, water in the water area can be sucked into the sliding cavity through the water inlet at the moment, then the water pushes the rotating plate open and is injected into the water taking cavity, when the water entering the water taking cavity passes through the blocking pressing plate, the blocking pressing plate is firmly pressed on one side of the fixed port by the water pressure at the moment, so that external water can not push the rotating plate open any more, and water sample collection at the first depth can be completed;
s3, as the first screw rod is meshed with the second screw rod through the first bevel gear and the second bevel gear, when the first screw rod rotates, the second screw rod also rotates, when the first sliding plate moves upwards, the second sliding plate moves leftwards in the exhaust cavity again, more water can enter the sliding cavity and the exhaust cavity at the moment, so that the dead weight of the sampling rack is larger and larger, the sampling rack can continue to sink, and then water resources in other water sampling cavities can be sampled according to the principle, the effect of simultaneously collecting water samples with different depths for a single time can be realized, and the sampling effect is improved;
s4, after the water samples are collected in the water sampling cavities, starting the driving motor to enable the driving end of the driving motor to rotate reversely, namely enabling the first sliding plate to move downwards, enabling the second sliding plate to move rightwards, namely enabling the water in the sliding cavity and the exhaust cavity to be completely discharged, wherein the buoyancy of the sampling frame is larger than the self weight, so that the sampling frame floats upwards towards the water surface, the situation that the driving motor is started to pull the sampling frame to the water surface can be avoided, and because the power required for the driving motor to start the empty winding rope is lower than that required for pulling the sampling frame while winding the rope, the electric energy of the driving motor can be further saved;
s5, it should be noted that when the sampling frame sinks in water for sampling, if there is reef below, can be detected by ultrasonic object detector at first, then with information display on the display screen to make the controller control start servo motor, make the third nut drive the rack and move in the base, simultaneously the rack can drive gear and pivot rotation, make the support column follow rotatory and adjust the direction of sampling frame, avoid sampling frame and reef collision, improved the security.
Compared with the prior art, the invention has the beneficial effects that:
1. by starting the driving motor, the first sliding plate can drive the first sealing ring to move upwards in the sliding cavity, at the moment, water in the water area can be sucked into the sliding cavity, so that the water can jack up the rotating plate and enter a plurality of water taking cavities, the effect of collecting water samples with different depths at one time can be realized, the sampling effect is improved, and the water in the water taking cavities can be prevented from automatically exuding by the collected water sample because the water pressure can firmly press the retaining plate on one side of the fixed port when the water in the water taking cavities passes through the retaining plate;
2. after the water samples are collected in the water sampling cavities, the driving motor is started to enable the driving end of the driving motor to rotate reversely, the first sliding plate can be moved downwards, the second sliding plate can be moved rightwards, water in the sliding cavity and the exhaust cavity can be completely discharged, at the moment, the buoyancy of the sampling frame is larger than the self weight, the sampling frame can float upwards to the water surface, the situation that the sampling frame is pulled to the water surface by starting the driving motor can be avoided, and because the power required for starting the empty winding rope by the driving motor is lower than that required by pulling the sampling frame while winding the rope, the electric energy of the driving motor can be saved;
3. the first screw rod and the second screw rod are respectively connected by using the first bevel gear and the second bevel gear in a meshed transmission way, so that a single driving motor can simultaneously control the rotation of the first screw rod and the second screw rod and play different roles, the electric energy consumed by the sampling device can be further saved, and the power consumption device is the same as the concept of energy conservation and environmental protection in China;
4. through setting up ultrasonic wave object detector, can detect the reef in the water area, when the reef that exists in the lower floor position below of sample frame was detected by ultrasonic wave object detector, can make the controller control start servo motor for the support column is rotatory and adjust the direction of sample frame, avoids sample frame and reef collision, has improved the security.
