[0003] In the prior art, when workers sample seawater, they can only sample seawater samples at the same depth each time. When sampling seawater at different depths, workers need to put the device into the seawater at different depths for multiple times to take samples. This operation process is not only complicated, but also reduces the efficiency of seawater sampling. At the same time, the amount of seawater samples sampled is small, making the results of seawater pollution detection inaccurate. In this regard, we propose a sampling device for marine pollution detection to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment 1:

[0023] like Figure 1-Figure 4 As shown, a sampling device for marine pollution detection includes a fixed plate 100, characterized in that: a motor 101 is fixedly mounted on the upper end of the fixed plate 100, and a sampling mechanism is provided on the lower end of the fixed plate 100;

[0024] The sampling mechanism includes a collection box 102, a rotating rod 105, a fixed frame 104 and a sealing plate 109. The collection box 102 is fixedly mounted at the lower end of the fixed plate 100, and the collection box 102 is evenly divided into four fan-shaped cavities 103. A fixed frame 104 is provided at the center of the lower end of the collection box 102. The rotating shaft of the motor 101 rotates through the fixed plate 100 and is fixedly connected to one end of the rotating rod 105. The other end of the rotating rod 105 is rotatably mounted on the upper end of the fixed frame 104. Each fan-shaped cavity 103 is fixedly provided with A support plate 106 and a wall of the support plate 106 are symmetrically provided with first telescopic rods 107, first springs 108 are provided inside the first telescopic rods 107, and a sealing plate 109 is fixedly installed at the end of each group of first telescopic rods 107, second telescopic rods 110 are symmetrically provided at the lower part of the rotating rod 105, second springs 111 are provided inside the second telescopic rods 110, and a pushing block 112 cooperating with the sealing plate 109 is fixedly installed at the end of the second telescopic rod 110, and a water discharge mechanism is provided on the outside of the collection box 102.

[0025] The fixing plate 100 is used to fix the collection box 102, the motor 101 is used to drive the rotating rod 105 to rotate, the center of the collection box 102 is hollow, and the four fan-shaped cavities 103 of the collection box 102 are respectively used to collect seawater at different depths, the fixing frame 104 can make the rotating rod 105 rotate more stably, and the rotation of the rotating rod 105 can drive the second telescopic rod 110 to move, the support plate 106 is used to fix the first telescopic rod 107, the first telescopic rod 107 is used to fix the sealing plate 109, the first spring 108 can make the sealing plate 109 always keep the fan-shaped cavity 103 in a closed state when no force is applied, the second telescopic rod 110 is used to fix the push block 112, the elastic force of the second spring 111 is greater than the first spring 108, so the push block 112 can push the sealing plate 109 to open the fan-shaped cavity 103;

[0026] When in use, the staff puts the device into seawater. When the first sampling position is reached, the motor 101 is turned on to drive the rotating rod 105 to rotate, so that the second telescopic rod 110 moves, and the pushing block 112 moves horizontally. When the pushing block 112 moves to abut against the sealing plate 109, since the elastic force of the second spring 111 is greater than the first spring 108, the sealing plate 109 is gradually pushed so that one of the fan-shaped cavities 103 is no longer in a closed state, and the seawater can flow into the collection box 102 for sampling. After a certain amount of seawater is collected in one of the cavities, the motor 101 is started again to drive the rotating rod 105 to continue to rotate, so that the pushing block 112 is no longer in contact with the sealing plate 109. At this time, the sealing plate 109 is pushed under the action of the first spring 108 to close the fan-shaped cavity 103, so that seawater no longer flows in and out, and the device continues to sink. At this time, the above steps can be repeated to collect seawater at different depths. After the seawater is collected in each fan-shaped cavity 103, the device can be taken out from the seawater to complete the seawater sampling and conduct pollution detection.

[0027] In this embodiment, by setting up a sampling mechanism, when the staff samples the seawater, they only need to put the device into the seawater to sample seawater samples of various depths at one time, without sampling in batches. In addition, the device has a simple structure and is easy to operate. It can collect a large amount of seawater at one time, which greatly improves the work efficiency of seawater sampling and the accuracy of seawater detection.

The outside of each fan-shaped cavity 103 is connected with a water outlet pipe 200. The water outlet pipe 200 is used to release the seawater. A water stop valve 201 is provided in the water outlet pipe 200. The water stop valve 201 is used to control the outflow of seawater in the fan-shaped cavity 103. The upper end of the water stop valve 201 is fixedly equipped with a rotating handle 202. The rotating handle 202 makes it convenient for the staff to open the water stop valve 201.

[0030] A water depth detection device 300 is provided in each fan-shaped cavity 103. The water depth detection device 300 is a prior art and will not be explained here. The water depth detection device 300 can detect the amount of collected seawater, and the water depth detection device 300 is electrically connected to the motor 101. When the fan-shaped cavity 103 is full of seawater, the rotation of the motor 101 can be controlled.

[0031] A plurality of connection rings 301 are fixedly provided on the upper end of the collection box 102. The connection rings 301 are used to connect the device to a crane to facilitate taking the device out of the seawater.

[0032] A counterweight ball 302 is fixedly connected to the lower end of the fixing frame 104, and the counterweight ball 302 can ensure that the device is immersed in the sea water and can sink.

[0033] A waterproof protective cover 303 is disposed outside the motor 101 , and the waterproof protective cover 303 is used to protect the motor 101 and extend the service life of the motor 101 .

[0034] After sampling the seawater, the device is taken out of the seawater, and the staff rotates the handle 202 to drive the water stop valve 201 to rotate, and open four different water outlet pipes 200 in sequence, so that the seawater collected in the collection box 102 flows out and is released;

[0035] In this embodiment, by providing a water discharge mechanism, it is convenient for the staff to sample and test the seawater of different depths collected in each fan-shaped cavity 103 .
