Technical Field

[0001] The present invention relates to the field of marine environment, and in particular to a sampling device for marine water quality survey. Background Art

[0002] Environmental protection departments need to regularly test the water quality of dams, lakes, etc.

[0003] The existing water quality sampling and detection device has a complex structure. When sampling at different water levels, samples can only be taken at each water level segment. Sampling is time-consuming and inefficient, and cannot meet people's needs. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the existing water quality sampling and detection devices, such as complex structure, which can only sample separately in each water level segment when sampling at different water levels. The sampling is time-consuming, inefficient, and cannot meet people's needs. A sampling device for marine water quality survey is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The top of the water pump stretches out the side of the water pump with a press-on / off switch, and the bottom of the water pump stretches out the side of the water pump to make the pump extend out of the water pump's reach.

[0007] Preferably, threads are provided on the outer sides of the two second rotating rods, and connecting blocks are threadedly connected to the two second rotating rods. A connecting rod is fixedly installed on one side of the connecting block, a long rod is rotatably installed on the connecting rod, and a wooden board is rotatably installed on the long rod.

[0008] Preferably, a rotating column is rotatably mounted on one side of the box body, a first gear is fixedly mounted on the rotating column, a second gear is fixedly mounted on the rotating shaft, and the first gear and the second gear are meshed with the same chain.

[0009] Preferably, a short column is fixedly mounted on the rotating shaft, a third gear is fixedly mounted on the short column, a fourth gear is fixedly mounted on the rotating shaft, and the third gear is meshed with the fourth gear.

[0010] Preferably, a threaded groove is provided on one side of the rotating column, a screw is threadedly connected to the inner thread of the threaded groove, a hose is fixedly installed on the water pipe, and one end of the screw is fixedly connected to the hose.

[0011] Preferably, a tooth plate is fixedly mounted on one side of the connecting column, the teeth on the tooth plate are engaged with the third gear, and a sliding groove is provided on the other side of the connecting column, and a short rod is slidably mounted in the sliding groove.

[0012] Preferably, two first bevel gears are fixedly mounted on the first rotating rod, and second bevel gears are fixedly mounted on the bottom ends of the two second rotating rods, and the first bevel gears are meshed with the second bevel gears.

[0013] Preferably, the water supply pipe is installed with a second control valve, the top of the inner wall of the water tank is provided with a water hole, one end of a water outlet pipe is installed in the water hole, and the other end of the water outlet pipe is communicated with the inside of the water pump.

[0014] Preferably, a collection box is fixedly mounted on the bottom of the inner wall of the box body, and a baffle is fixedly mounted on the inner wall of the collection box.

[0015] Preferably, water inlet pipes are fixedly installed on both sides of the inner wall of the water tank, a first control valve is installed on the two water inlet pipes, and one end of the water inlet pipe extends to the outside of the water tank.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] This solution is provided with a moving motor, a rotating shaft, a fourth gear, a third gear, a connecting column, a water tank and a water pump. When the motor is working, the motor rotates to drive the rotating shaft, the fourth gear and the third gear to rotate, driving the connecting column to move downward, so that the connecting column drives the water tank and the water pump fixed at the bottom of the connecting column to move downward. When it moves to a suitable position, the control valve on the water inlet pipe is opened to allow seawater to enter the water tank. Then the water pump is started, and the water pump transports the filtered seawater through the water pipe to the seawater collection box inside the box. As the connecting column continues to move downward, seawater at different depths is sampled.

[0018] Since a rotating shaft, a first gear, a second gear, a chain, a connecting column, a screw and a hose are provided, while sampling, the rotating shaft rotates to drive the first gear to rotate, and the second gear is driven to rotate through the chain. Since the second gear is fixedly mounted on the connecting column, when the second gear rotates, it drives the connecting column to rotate, drives the screw to move, and the screw drives the hose to move, thereby transporting seawater of different depths to different collection boxes for classification and detection.

[0019] The present invention has a simple structure, and the sampling and detection device can sample water in different water level sections, thereby improving the practicability of the sampling and detection device. BRIEF DESCRIPTION OF THE DRAWINGS

A first rotating rod 25 is rotatably installed on the inner wall of the box body 4, and a mounting groove 35 is provided at the bottom end of the two fixed columns 2. A fixing rod 34 is fixedly installed on the inner wall of the two mounting grooves 35, and a second rotating rod 23 is rotatably installed on the fixed rod 34.

[0028] In this embodiment, threads are provided on the outer sides of the two second rotating rods 23, and connecting blocks 24 are threadedly connected to the two second rotating rods 23. A connecting rod 33 is fixedly installed on one side of the connecting block 24, and a long rod 32 is rotatably installed on the connecting rod 33, and a wooden board 38 is rotatably installed on the long rod 32.

[0029] In this embodiment, a rotating column 17 is rotatably mounted on one side of the box body 3, a first gear 18 is fixedly mounted on the rotating column 17, a second gear 16 is fixedly mounted on the rotating shaft 6, and the first gear 16 and the second gear 18 are meshed with the same chain 19.

[0030] In this embodiment, a short column 37 is fixedly mounted on the rotating shaft 6 , a third gear 29 is fixedly mounted on the short column 37 , and a fourth gear 28 is fixedly mounted on the rotating shaft 6 . The third gear 29 meshes with the fourth gear 28 .

[0031] In this embodiment, a threaded groove 20 is formed on one side of the rotating column 17 , a screw rod 21 is connected to the inner thread of the threaded groove 20 , a hose is fixedly mounted on the water pipe 27 , and one end of the screw rod 21 is fixedly connected to the hose.

[0032] In this embodiment, a tooth plate is fixedly installed on one side of the connecting column 7, and the teeth on the tooth plate are engaged with the third gear 29. A sliding groove 13 is opened on the other side of the connecting column 7, and a short rod 14 is slidably installed in the sliding groove 13.
