[0036] Figures 1 to 4 The structure of the reciprocating CTD profile detection device according to an embodiment of the present application is schematically shown.

[0037] As Figures 1 to 4 shown, the reciprocating CTD profile detection device comprises:

[0038] The body 1 is internally provided with a first cabin 2, a second cabin 3, and a third cabin 4, and the third cabin 4 is internally provided with chemical reaction particles;

[0039] The probe module 5 is arranged on the body 1 and is provided with a salinity detector, a temperature detector, and a depth detector;

[0040] The first piston 6 is arranged in the first cabin 2;

[0041] The second piston 7 is arranged between the first cabin 2 and the second cabin 3 to separate the first cabin 2 and the second cabin 3, and the first cabin 2 stores seawater, and the second cabin 3 stores a chemical reaction liquid agent capable of generating gas with the chemical reaction particles;

[0042] The first electromagnetic valve is arranged on the side wall of the first cabin 2 to control the conduction or closing of the first cabin 2 to the outside;

[0043] The second electromagnetic valve is arranged on the side wall of the second cabin 3 to control the conduction or closing of the second cabin 3 to the outside;

[0044] The third electromagnetic valve is arranged between the second cabin 3 and the third cabin 4 to control the conduction or closing of the second cabin 3 and the third cabin 4;

[0045] The first driving assembly 8 is arranged to drive the first piston 6 to move in the first cabin 2;

[0046] A control module is electrically connected with the first electromagnetic valve, the second electromagnetic valve, the third electromagnetic valve and the first driving assembly 8 respectively. In detail, a lithium battery for supplying power to the control module and other electrical components is installed inside the machine body 1, and a solar cell can also be installed outside the machine body 1 to charge the lithium battery; the first electromagnetic valve, the second electromagnetic valve and the third electromagnetic valve are all in a closed state in an initial state.

[0047] Working process: the working ship carrying the present application sails to the preset sea area, and then the staff releases the present application from the ship into the seawater, allowing it to sink naturally. The salinity detector, temperature detector and depth detector on the probe module 5 all start data collection work during the sinking process, and real-time data transmission and storage to the control module. When the depth detector detects that the present application has sunk to the preset depth, the control module instructs the first driving assembly 8 to drive the first piston 6 to move and extrude in the first chamber 2 towards the second chamber 3, and at the same time, the control module instructs the third electromagnetic valve to open, so that the second chamber 3 and the third chamber 4 are connected. When the first piston 6 moves and extrudes in the first chamber 2 towards the second chamber 3, the second piston 7 will also displace and compress the second chamber 3 at the same time, so that the chemical reaction liquid agent in the second chamber 3 enters the third chamber 4 and reacts with the chemical reaction particles to produce gas. The gas will be filled into the second chamber 3 from the third chamber 4, increasing the pressure inside the second chamber 3, and at the same time, it also increases the pressure inside the first chamber 2. After the third electromagnetic valve is opened for a preset time, the control module instructs the third electromagnetic valve to close, and then instructs the first electromagnetic valve to open. Under the push of the pressure in the first chamber 2 and the second chamber 3, the seawater in the first chamber 2 is discharged to the outside from the machine body 1, and then the first electromagnetic valve is closed, thereby reducing the overall density of the present application and increasing the overall buoyancy, so that the present application floats up. The probe module 5 also collects salinity, temperature and depth data during the floating process. When it floats to the preset depth, the control module instructs the first electromagnetic valve to open, and the first driving assembly 8 drives the first piston 6 to move away from the second chamber 3 in the first chamber 2, so as to suck seawater into the first chamber 2, increase the overall density of the present application, and make the overall density of the present application. The present application starts to sink again. In addition, the control module also instructs the second electromagnetic valve to open for a short time to discharge the excess gas in the second chamber 3, further accelerating the switching of the present application to the sinking state; thereby realizing multiple sinking and floating reciprocating motion, and repeatedly completing the profile detection of the preset sea area. In this process, the working ship does not need to wait for a long time, and after the release is completed, it can sail to the next sea area position for release and detection work, saving time and improving work efficiency.

In other embodiments, a threaded hole can be formed on the support rod 9, and a nut driven by the motor can be arranged on the first driving assembly 8 and matched with the threaded hole.

[0049] In the embodiment, the support rod 9 extends into the second cabin 3 in a sealed manner, so that the second piston 7 can move along the support rod 9 when the first driving assembly 8 drives the first piston 6 to move towards the second cabin 3. In this way, the second piston 7 can stably move along the support rod 9 when the first driving assembly 8 drives the first piston 6 to move towards the second cabin 3, thereby enhancing the reliability of the work.
