[0002] The comprehensive test tank is the most important facility in the field of ship and ocean engineering, and can conduct various civil and military ship and submersible model tests. When a submersible encounters an emergency during underwater navigation, for example: being attacked and about to sink, or the submersible exploding and sinking, or suddenly encountering a water layer with a sharp change in density in the vertical direction, resulting in a decrease in buoyancy and a sharp drop to the seabed (commonly known as "depth drop"). When encountering these very dangerous situations, it is urgent for the submarine to float to ensure that the submarine does not sink into the sea. In response to this, an emergency floating device adapted to the submarine has been developed. However, before the emergency floating device is put into use on the submersible, it usually needs to be verified to ensure the reliability of the submersible emergency floating device and minimize the risk.

Referring to Figure 1 as shown, the test equipment for the towing release and floating up of the submerged body includes a limit guiding device 1, a towing vehicle 2 and a locking and releasing device 3.

[0030] The limit guiding device 1 is arranged in a deep pool with a depth of 10 meters. The towing vehicle 2 is movably arranged on the limit guiding device 1. The locking and releasing device 3 is fixedly arranged on the towing vehicle 2 and moves synchronously with the towing vehicle 2, and is used for locking and releasing the submerged body to be tested.

[0031] During the floating up test, the locking and releasing device 3 locks the submerged body to be tested onto the towing vehicle 2. The towing vehicle 2 travels regularly along the limit guiding device 1. When it travels to a specified position, the submerged body to be tested is released, and the submerged body to be tested floats up to complete the test.

[0032] In the above process, the so-called regular travel specifically means reaching a specified moving speed within a specified distance, and moving at this speed uniformly for a certain distance. During this period, the model is released. After the model is released, it decelerates and stops within the specified distance.

[0033] The utility model can effectively limit the traveling track of the towing vehicle 2 through the limit guiding device 1 to ensure its traveling effect. Through the mutual cooperation of the towing vehicle 2 and the locking and releasing device 3, on the one hand, the submerged body to be tested can smoothly complete regular travel, and on the other hand, the submerged body is released, enabling the floating up test of the submerged body. Not only is the test operation convenient, but also the test effect is remarkable.

[0037] The support frame 11 is arranged in the deep pool. The support frame 11 is of a frame structure and is the main load-bearing member. The track 12 is fixedly arranged on the support frame 11. The moving device 4 is movably arranged on the track 12. The track 12 and the moving device 4 cooperate with each other to effectively limit the moving track of the towing vehicle 2 and ensure its traveling effect.
