Description

Technical Field

[0001] This invention belongs to the field of underwater escape training, specifically an underwater escape training simulator. Background Technology

[0002] In the training of submarine crew members, it is necessary to train them to escape underwater in emergency situations. According to the patent document with authorization announcement number "CN216352876U" and invention title "Underwater Escape Simulator and Underwater Escape Simulation Component," the description states that: the buoyancy chamber generates buoyancy, pushing the main body to rotate, while the pneumatic tilting component moves along the rotating ring. During the movement, by controlling the supply and cutoff of compressed air, the pneumatic tilting component can brake at any position, stopping the simulator from tilting, thus simulating different tilting and overturning situations of a helicopter underwater, better facilitating the training of relevant personnel. However, the following shortcomings still exist:

[0003] In the event of an emergency, a submarine may leak water, necessitating training in underwater escape procedures in such situations. Summary of the Invention

The top of the submarine simulation compartment has a simulation compartment outlet, and the top of the simulation compartment outlet has a hatch. Water inlet valves are symmetrically installed at the top and bottom of the submarine simulation compartment. The water inlet valves on the upper and lower sides are used to control the direction of water intake in the submarine simulation compartment. Rotary shafts are symmetrically installed at both ends of the submarine simulation compartment, and a first pulley is installed on one of the rotating shafts.

[0008] Preferably, the sliding groove is slidably connected to a sliding block, and a rotating groove is provided on the side of the two sliding blocks that are close to each other. The rotating groove is rotatably connected to the rotating shaft.

[0009] Preferably, the drive assembly includes a movable plate installed inside the upper frame. One end of the movable plate is slidably connected to one of the sliding grooves. A side plate is provided on the side of the movable plate near the other sliding groove. The side plate is slidably connected to the sliding groove. Limiting grooves are provided on the sides of the movable plate and the side plate that are close to each other. A large gear is provided between the movable plate and the side plate. A second pulley is installed on the side of the large gear near the side plate. Limiting blocks are installed on the sides of the second pulley and the large gear that are far from each other. The limiting blocks are rotatably connected to the limiting grooves. The large gear and the second pulley are coaxially arranged. A training adjustment assembly is installed above the large gear.

[0010] Preferably, the second pulley is located above the first pulley, and a belt is installed on the outer side of the second pulley and the first pulley. A fixing rod is installed at the bottom end of the moving plate, and the bottom end of the fixing rod is fixedly connected to the sliding block below.

[0011] Preferably, the movable plate is internally threaded with a screw rod, which is rotatably connected to the upper frame. One end of the screw rod is fixedly connected to the output shaft of the motor, and the motor is fixedly mounted on the upper frame.

[0012] Preferably, the training adjustment component includes a rack located above the large gear, with side blocks symmetrically installed at both ends of the rack, and movable rods installed at the bottom ends of the side blocks. The upper frame has symmetrical movable slots inside, and the movable rods are movably installed inside the movable slots. A bottom block is installed at the bottom end of the movable rods, and the bottom block is located below the upper frame. Slots are provided on the sides of the two movable rods that are far apart from each other.

[0013] Preferably, fixed seats are symmetrically installed on both sides of the upper frame. The interior of the fixed seats is formed by an inner groove, which is connected to the interior of the movable groove. The inner groove is located below the slot. A top rod is movably installed inside the inner groove. A locking rod is provided on the side of the top rod near the movable groove. A spring is installed between the locking rod and the top rod. A second magnetic block is installed on the top rod, and a first magnetic block is installed on the locking rod. The magnetic properties of the first magnetic block are the same as those of the second magnetic block. An electromagnet is installed on the side of the fixed seat away from the movable groove.

[0014] Preferably, the bottom end of the inner groove is provided with a bottom groove, the bottom end of the top rod is equipped with a limiting block, the limiting block is slidably connected to the bottom groove, and a rotating rod is provided between the limiting block and the bottom block, with both ends of the rotating rod being rotatably connected to the limiting block and the bottom block respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In this invention, by opening water inlet valves in different directions, water can enter the interior of the submarine simulation chamber from different directions. When the submarine is damaged, seawater enters the submarine from different directions. Trainees need to escape from the water surface in the environment where the water inlet valves are open, thus facilitating the training of trainees.

[0017] (2) The invention drives the moving plate to move back and forth along the sliding groove by turning on the motor. The moving plate is fixedly connected to the sliding block on the submarine simulation cabin by the fixed rod, thereby driving the submarine simulation cabin to move back and forth along the sliding groove. The simulation submarine loses control and moves sideways with the water flow. The trainees need to escape from the water surface while the submarine simulation cabin is constantly moving, which increases the difficulty of training and improves the trainees' escape ability.

[0018] (3) The invention moves the rack downward to mesh with the large gear, and the moving plate moves laterally, so that the large gear rotates under the action of the rack, which drives the second pulley to rotate. Through the transmission of the belt and the first pulley, the submarine simulation cabin rolls itself during the movement, thereby further increasing the training difficulty and improving the escape ability of the trainees.

[0019] (4) When a positive current is applied to the electromagnet, the push rod moves toward the locking rod under the repulsive force of the electromagnet, causing the movable rod to move downward to the position corresponding to the locking groove and the locking rod. Under the elastic force of the spring, the locking rod quickly enters the slot, thereby fixing the rack and meshing with the large gear. When a reverse current is applied to the electromagnet, the locking rod leaves the slot under the attractive force of the electromagnet. Then the push rod moves back and causes the movable rod to move upward, thereby disengaging the rack from the large gear. This facilitates the adjustment of training difficulty and improves training effect. Attached Figure Description

A limit block 1016 is installed at the bottom end of the top rod 1011. The limit block 1016 is slidably connected to the bottom groove 1010. A rotating rod 1017 is provided between the limit block 1016 and the bottom block 1005. The two ends of the rotating rod 1017 are rotatably connected to the limit block 1016 and the bottom block 1005, respectively.

[0034] Working principle: When in use, the hatch 803 is opened, and the trainees enter the submarine simulation compartment 801 from the simulation compartment exit 802 to prepare for training. The hatch 803 is closed, and the equipment is lowered into the water by a crane. In the first stage of training, the water inlet valves 804 in different directions are opened, so that water can enter the submarine simulation compartment 801 from different directions. This simulates when the submarine is damaged and seawater enters the submarine from different directions. The trainees need to escape to the surface in the environment where the water inlet valves 804 are open, thus facilitating the training.

[0035] The second phase of training then begins. Motor 903 is activated, causing screw 902 to rotate. Since screw 902 is threadedly connected to moving plate 901, it drives moving plate 901 to move back and forth along sliding groove 7. Moving plate 901 is fixedly connected to sliding block 806 on submarine simulation chamber 801 via fixed rod 910, thus causing submarine simulation chamber 801 to move back and forth along sliding groove 7. This simulates a submarine losing control and drifting sideways with the water flow. Trainees need to escape the water while submarine simulation chamber 801 is constantly moving, increasing the difficulty of the training and improving the trainees' escape ability.

[0036] The third stage of training then begins. A positive current is applied to the electromagnet 1009, causing the second magnetic block 1015 on the push rod 1011 to be repelled by the electromagnet 1009. This causes the push rod 1011 to move towards the locking rod 1012. The locking rod 1012, however, is blocked by the movable rod 1004 and cannot move. As the push rod 1011 moves, it drives the movable rod 1004 downwards via the rotating rod 1017, causing the rack 1001 to move downwards. When the rack 1001 reaches the position where it meshes with the large gear 906, the movable rod 1004 moves downwards to the position corresponding to the locking rod 1012 in the slot 1006. At this point, the locking rod 1012 quickly enters the slot 1006 under the elastic force of the spring 1013. With the rack 1001 fixed, the moving plate 901 moves laterally, causing the large gear 906 to rotate under the action of the rack 1001. This, in turn, drives the second pulley 905 to rotate. The second pulley 905, through the transmission of the belt 907 and the first pulley 808, causes the submarine simulation chamber 801 to roll during the movement, thereby further increasing the training difficulty and improving the escape ability of the trainees. When the difficulty is adjusted, a reverse current is applied to the electromagnet 1009, causing the locking lever 1012 to move back away from the locking slot 1006 under the attraction of the electromagnet 1009. Subsequently, the push rod 1011 moves back, causing the movable rod 1004 to move upward, thereby disengaging the rack 1001 from the large gear 906, thus facilitating the adjustment of the training difficulty.
