Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality detection device for multi-depth sampling. Background Art

[0002] Water quality testing can detect the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluate the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage, etc. Sampling is required when testing water quality.

[0003] After searching the Chinese patent "A depth-adjustable water quality detection sampling device", the publication number is "CN219608528U". This patent drives the sampling head to dive and float in the water through a water tank. The principle of the water tank is the same as that of a submersible. The dead weight is changed by controlling the amount of water in the tank, thereby changing the buoyancy. The position of the sampling head in the water is adjusted by controlling the position of the water tank 4 in the water, so that water at different positions and depths in the water can be collected. However, when sampling water quality, this device is not convenient for quickly sampling and testing water quality at different depths, which reduces the use effect of the device.

[0004] Therefore, a water quality detection device with multi-depth sampling is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a water quality detection device with multi-depth sampling in order to solve the above problems, thereby improving the problem of inconvenient and inefficient rapid sampling and detection of water quality at different depths.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a multi-depth sampling water quality detection device, comprising a bottom plate, two collecting rollers are fixedly connected to the top of the bottom plate, and a traction rope is arranged on the surface of the collecting roller; a sampling mechanism, which can quickly sample and detect water quality at different depths, and the sampling mechanism is arranged at one end of the traction rope; wherein the sampling mechanism comprises two sampling barrels arranged at one end of the traction rope, one of the sampling barrels is fixedly connected to one of the traction ropes, a water storage tank is opened on the inner wall of the sampling barrel, and a limiting component is arranged on the outer wall of the sampling barrel.

[0007] Preferably, the sampling mechanism also includes a sealing block slidably connected to the middle part of the inner wall of the water tank, the bottom end of the sealing block is clamped with the water tank, one of the sealing blocks is fixedly connected to the other traction rope, a compression spring is provided at the top of the sealing block, one end of the other traction rope passes through two sampling tubes in sequence and is fixedly connected to the other sealing block, the sealing block fits tightly with the sampling tube to prevent water leakage, and can sample and detect water quality at different depths, thereby improving the detection accuracy of the device.

[0008] Preferably, a sealing ring is fixedly connected to the inner bottom wall of one of the sampling cylinders, which can improve the sealing performance of one of the sampling cylinders when the other traction rope moves up and down.

[0009] Preferably, a filter is fixedly connected to one side of the sampling tube, a water inlet is opened on one side of the surface of the sampling tube, the filter is fixedly connected in the water inlet, and when the sealing block moves upward, the sampling tube samples the water quality through it, and the filter filters impurities and garbage.

[0010] Preferably, one side of the sampling tube is connected to a drain pipe, and one end of the drain pipe is threadedly connected to a sealing cap to facilitate taking out the water flow after sampling.

[0011] Preferably, the limiting assembly includes a fixed block fixedly connected to the bottom end of one of the sampling tubes, and the top end of the other sampling tube is rotatably connected to a connecting block. A telescopic ring is arranged between the two sampling tubes. When sampling water quality, the sampling positions of the two sampling tubes can be adjusted by the telescopic ring, so that water quality at different depths can be sampled.

[0012] Preferably, both sides of the sampling tube are fixedly connected with a fixing plate, the top of the fixing plate is fixedly connected with a fixing rod, and the top of the fixing plate is provided with a plurality of evenly distributed counterweight blocks, which can counterweight the sampling tube, increase the weight of the sampling tube, prevent the sampling tube from being displaced during sampling, and prevent the sampling tube from moving when another traction rope drives the sealing block to move upward.

[0013] Preferably, one end of the fixing rod passes through the counterweight block and is threadedly connected to a limiting plate, so that the counterweight block on the fixing plate can be fixed and limited.

[0014] The beneficial effects of the utility model are:

[0015] 1. By setting up a sampling mechanism, when sampling water quality at different depths, one of the collecting rollers is rotated to drive two sampling barrels into the water for sampling through one of the traction ropes. The position of the sampling barrel can be adjusted by controlling one of the traction ropes. The other traction rope can drive the sealing block to move upward, and cooperate with the water inlet and the filter to sample the water flow. The sealing block is elliptical, and the sealing block cooperates with the compression spring to seal the water storage tank. The drain pipe cooperates with the sealing cover to take out the water sample in the water storage tank. The sealing ring can seal the other traction rope when it moves. The other sampling barrel is set under one of the sampling barrels, which can sample water quality at different depths and improve the detection effect of the device.

[0016] 2. By setting the limit assembly, when sampling water quality at different depths, the distance between the two sampling tubes can be increased by adjusting the fixed ring, so that the two sampling tubes can detect water quality at different depths. The fixed block and the connecting block can be used to fix the telescopic ring in the fixed block, which is convenient for carrying and collecting the sampling tube when not in use. The counterweight blocks on both sides of the sampling tube can increase the weight of the sampling tube to prevent the sampling tube from being displaced during sampling, and can also prevent the sampling tube from moving upward when another traction rope drives the sealing block to move upward. The fixed rod and the limit plate can be used to fix the counterweight block, and the position of the sampling tube can be adjusted to facilitate sampling of water quality at different depths.
