Description

Technical Field

[0001] This utility model relates to the field of water body sampling technology, specifically a multi-layer water body sampling device. Background Technology

[0002] Water resources are an important resource, and people's daily lives are inseparable from the use of water resources. In order to accurately monitor the quality of water sources, it is necessary to regularly sample and test water resources (rivers and lakes). The sampling method usually involves using an extraction device connected to an external water pipe to test the water body. However, sampling is not accurate enough for water bodies at different depths, and there are also certain limitations on the area. Operators cannot be too far away from the water source. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a multi-layer water sampling device. The technical solution adopted includes a flat plate, a bottom mounting frame, a rotating shaft, moving wheels, air bladders, inflation / deflation ports, an upper mounting frame, a stepper motor, an upper rotating shaft, a take-up / deployment rope, a top block, a stabilizing part, a plug-out part, a connecting rod, a base plate, a bottom fixing rope, a counterweight ball, a water container, a water inlet, and a sealing plug. The bottom mounting frame is integrally formed on both the left and right sides of the bottom of the flat plate. The rotating shaft is mounted on the bottom mounting frame in the front and back directions. Moving wheels are fixed on the front and rear ends of the rotating shaft. Several air bladders are evenly fixed on the ground of the flat plate. An inflation / deflation port is located on the front of the airbag, sealed by a removable plug. The presence of wheels facilitates movement of the flatbed, while the airbag allows it to float on the water after inflation, providing flexibility in its position. However, when the flatbed is far from the shore, holes need to be pre-drilled in the flatbed for subsequent traction. A through-hole is cut in the center of the flatbed, with integrated upper mounting brackets on both sides. A stepper motor is fixed to the left side of the upper mounting bracket, and the output shaft of the stepper motor extends from the through-hole in the upper mounting bracket to the right side, where it is fixed to a fixed end. The upper rotating shaft is fixedly connected, and its movable part is inserted into the through holes in the left and right directions of the upper mounting bracket on the right side. The stepper motor is powered by a battery and controlled by a remote control. The power supply and control methods are conventional technologies and do not need to be described in detail. The top end of the take-up and release rope is fixed to the upper rotating shaft and wound around it. The other end extends downward and is fixedly connected to a top block. The position of the top block corresponds to the position of the through slot on the flat plate. The four corners of its lower surface are integrally formed connecting rods, and the bottom of the connecting rods is fixed to the base plate. When the stepper motor starts and drives the upper rotating shaft to rotate, it can complete the take-up and release of the rope, thereby allowing the base plate to enter... The lifting mechanism ensures that the number of rotations of the upper shaft is constant with each rotation of the stepper motor, and the length of the pulling or releasing rope is also fixed. Therefore, this method allows for sampling and accurate control of water depth at different depths. A bottom fixing rope is fixedly connected to the bottom surface of the base plate, and a counterweight ball is fixedly connected to the lower end of the bottom fixing rope. A water-holding cylinder is fixed to the base plate, with water inlets on the upper left side and the lower right side of the water-holding cylinder, both sealed with plugs. The left sealing plug is connected to the plug-pulling part. After reaching the corresponding water depth, the left sealing plug is pulled out through the plug-pulling part, and water is poured into the water-holding cylinder.

[0004] As a preferred technical solution of this utility model, the stabilizing part includes an L-shaped baffle and a top limiting plate. The L-shaped baffle is integrally formed at the four corners of the through groove opening in the middle of the flat plate, and the top limiting plate is integrally formed on the top of the L-shaped baffle. The side of the top block contacts the inner wall of the L-shaped baffle, and chamfered surfaces are opened on all four sides of the top block.

[0005] As a preferred technical solution of this utility model, the plug-out part includes a left rotating shaft, a motor and a pull-out rope. The motor is installed on the front side of the upper mounting bracket on the left side. The output shaft of the motor extends from the through hole on the front side of the upper mounting bracket to the rear side and is fixedly connected to the left rotating shaft at its output end. One end of the pull-out rope is fixed to the left rotating shaft and wound around it, and the other end is fixedly connected to the sealing plug. Since the pull-out rope is in a taut state, it can help stabilize the top block and prevent it from rotating randomly.

[0006] As a preferred technical solution of this utility model, the counterweight ball is made of iron.

[0007] As a preferred technical solution of this utility model, the sealing plug is a rubber sealing plug.

[0008] The beneficial effects of this utility model are as follows: the airbag design allows the flat plate to float on the water surface, making it more flexible to sample from different locations. The stepper motor and remote control device drive the upper shaft to rotate, releasing the reel and release rope, which allows the top block to descend into the water under the action of the fitted ball. The depth of the probe can be easily controlled by the number of rotations of the stepper motor. The water is released by the sealing plug in the water outlet on the left side of the water tank, which is located in the water, and water is poured into the water tank to complete the depth sampling.
