[0001] This utility model relates to the field of water sampling support technology, specifically a multifunctional CTD water sampling support. Background Technology

[0002] A water sampler typically consists of an inlet, an outlet, a sealing device, a triggering device, and a fixed frame. Some advanced water samplers are also equipped with sensors that can measure parameters such as water temperature, salinity, and dissolved oxygen in real time. It is mainly based on the principle of sealing and opening / closing control. When the water sampler reaches the target water layer, the inlet of the water sampler is opened through mechanical, electronic, or chemical triggering methods, and the water sample enters the water sampler. Then the inlet is closed, and the water sample is sealed and preserved for analysis in the laboratory.

[0003] CTD (Conductivity, Temperature, Depth) sampling bracket is a specialized device used for marine scientific research and water sampling. The bracket is used to fix the CTD (Conductivity, Temperature, Depth) meter and the water sampler together, so that the two instruments can be used together.

[0004] Regarding the existing related technologies, the inventor believes that there are the following drawbacks: After the existing water sampler has been collected, it needs to be lifted to the ground by a support, and then the staff needs to manually seal the bottom of the water sampler to prevent water leakage, which is quite troublesome. Utility Model Content

[0005] To address the cumbersome technical problem that existing methods require manual closure of the water sampler's lower inlet after it has been lifted to the ground using a support frame, this invention provides a multifunctional CTD water sampling support frame.

[0006] This utility model is achieved using the following technical solution: a multifunctional CTD water sampling bracket, including a fixed bracket, a water sampler fixedly connected to the middle of the fixed bracket, a temperature, salinity, and depth meter fixedly connected to one side of the fixed bracket, a ring frame fixedly connected to the top of the fixed bracket, an inner cavity provided inside the water sampler, a flap rotatably connected inside the inner cavity, a connecting block fixedly connected to one end of the flap, a fixed ring provided at the bottom of the fixed bracket, a movable rod fixedly connected to the top of the fixed ring, a fixed cylinder fixedly connected to the middle of the movable rod, a return spring provided outside one end of the movable rod, and the top of the movable rod movably connected to the inside of the water sampler, with the top of the movable rod in contact with the connecting block.

[0010] Preferably, one end of the return spring is fixedly connected to the inside of the sleeve, and the other end of the return spring is fixedly connected to the bottom of the water sampler.

[0011] Preferably, the water sampler has a movable groove machined on one side inside, the top of the movable rod is movably connected to the inside of the movable groove, and the connecting block is movably connected to the inside of the movable groove.

[0012] Preferably, the two ends of the flap are fixedly connected to two rotating shafts, which are rotatably connected to both sides of the inner wall of the inner cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, the fixed bracket and water sampler are pulled out of the water surface by the rope at the top of the ring frame. Then the fixed bracket is moved and placed on the ground, and the fixed ring will contact the ground.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1: Please refer to Figure 1 - Figure 2This embodiment of a multifunctional CTD water sampling bracket includes a fixed bracket 1, a water sampler 2 fixedly connected to the middle of the fixed bracket 1, a temperature, salinity and depth meter 3 fixedly connected to one side of the fixed bracket 1, a ring frame 4 fixedly connected to the top of the fixed bracket 1, an inner cavity 8 inside the water sampler 2, a flap 9 rotatably connected inside the inner cavity 8, a connecting block 16 fixedly connected to one end of the flap 9, a fixed ring 10 at the bottom of the fixed bracket 1, a movable rod 11 fixedly connected to the top of the fixed ring 10, a fixed cylinder 12 fixedly connected to the middle of the movable rod 11, a return spring 14 on the outside of one end of the movable rod 11, and the top of the movable rod 11 movably connected to the inside of the water sampler 2, with the top of the movable rod 11 in contact with the connecting block 16.

[0020] When the water sampler 2 finishes sampling, the fixed support 1 and the water sampler 2 are pulled out of the water surface by the rope at the top of the ring frame 4, so that the fixed support 1 is moved to the ground. When the fixed support 1 is placed on the ground, the fixed ring 10 will contact the ground, so that the fixed ring 10 drives the movable rod 11 to move upward, so that the movable rod 11 moves upward along the inside of the movable groove 15 and contacts the connecting block 16. The connecting block 16 is fixed by the movable rod 11, which facilitates the fixing of the flap 9 and prevents water leakage inside the inner cavity 8 caused by the movement of the flap 9.

[0021] Furthermore, multiple fixed columns 6 are fixedly connected around the fixed bracket 1. The temperature, salinity, and depth meter 3 is fixedly connected to one side of two fixed columns 6. The top of the water sampler 2 is fixedly connected to one side of the top fixed column 6. The water sampler 2 and the temperature, salinity, and depth meter 3 are fixed to one side of the fixed column 6 by bolts, which facilitates the installation and disassembly of the water sampler 2 and the temperature, salinity, and depth meter 3.

[0022] Furthermore, two counterweights 5 are fixedly connected to both ends of the bottom of the fixed bracket 1. By setting the counterweights 5, the weight of the fixed bracket 1 can be increased, and the center of gravity of the fixed bracket 1 can be adjusted to prevent the fixed bracket 1 from tilting when rising and falling.

[0023] Furthermore, the bottom of the fixed bracket 1 is fixedly connected to the base plate 7, the movable rod 11 is movably connected inside the base plate 7, and the fixed cylinder 12 is located at the top of the base plate 7. When the fixed ring 10 drives the movable rod 11 to move upward, the movable rod 11 will drive the fixed cylinder 12 to move upward.

[0024] Furthermore, one end of the return spring 14 is fixedly connected to the inside of the sleeve 13, and the other end of the return spring 14 is fixedly connected to the bottom of the water sampler 2. With the return spring 14 provided, when the fixed cylinder 12 drives the sleeve 13 to move, the sleeve 13 will drive the return spring 14 to compress. When the fixed ring 10 is released, the return spring 14 returns to its original length and drives the sleeve 13 to move, thereby making the fixed cylinder 12 contact the top of the bottom plate 7.

[0025] Furthermore, a movable groove 15 is machined on one side of the inside of the water sampler 2. The top of the movable rod 11 is movably connected to the inside of the movable groove 15, and the connecting block 16 is movably connected to the inside of the movable groove 15. By providing the movable groove 15, the movable groove 15 will limit the movement of the movable rod 11, so that the movable rod 11 remains stable when it moves.

[0026] Furthermore, two rotating shafts 17 are fixedly connected to both ends of the flap 9. The two rotating shafts 17 are rotatably connected to both sides of the inner wall of the inner cavity 8. In the prior art, when the water sampler 2 is placed in the water, the water pushes open the lower cover plate to allow water to enter the cylinder. The water entering the cylinder pushes open the upper cover plate. When the main body reaches the predetermined depth, it is pulled up. At this time, the cylinder floats upward, and the water pressure causes the upper and lower cover plates to close, sealing the water inside the cylinder. This ensures that the water inside the cylinder is a water sample at the predetermined depth. When the water pushes open the flap 9, the flap 9 will rotate around the rotating shafts 17. By setting the rotating shafts 17, the rotating shafts 17 will limit the rotation of the flap 9.

[0027] Working principle: After the water sampler 2 finishes sampling, the fixed support 1 and the water sampler 2 are pulled out of the water surface by the rope at the top of the ring frame 4. Then the fixed support 1 is moved and placed on the ground, and the fixed ring 10 will contact the ground. At the same time, the fixed ring 10 will drive the movable rod 11 and the fixed cylinder 12 to move upward, so that the movable rod 11 moves along the inside of the movable groove 15 and contacts the connecting block 16. The connecting block 16 is fixed by the movable rod 11, which facilitates the fixing of the flap 9 and prevents water leakage inside the inner cavity 8 caused by the movement of the flap 9.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
