Description

Technical Field

[0001] The present invention relates to the technical field of underwater ballast components, and more particularly to a ballast component for an underwater delivery training device. Background Art

[0002] Underwater training greatly improves the physical fitness of underwater workers and improves the efficiency and success rate of subsequent underwater operations. The hydraulic delivery device used in training needs to dive to a corresponding depth to facilitate the delivery of materials to underwater trainees, and also to facilitate the underwater trainees to replenish oxygen at any time. Although the underwater delivery equipment used in the existing technology can also meet the training requirements, the volume of its ballast component is fixed, so when the water volume in the ballast tank is small, it cannot be filled. Then the water will shake in the ballast tank, increasing the overall shaking rate of the preparation and reducing stability. Moreover, as the diving depth increases, the underwater simulated water flow or the simulated movement of large underwater organisms will cause a strong impact on the equipment, increasing its shaking frequency, thereby further reducing its stability.

[0003] Therefore, it is necessary to develop a new type of underwater delivery training ballast assembly that is sufficiently stable and can continuously provide material supplies to trainees. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, the present invention provides a ballast assembly for an underwater delivery training device, comprising a ballast tank 1, a delivery compartment 2 being sealably welded to the top of the ballast tank 1, a storage compartment 3 being provided in the middle of the ballast tank 1, a drainage compartment 4 being provided at the bottom of the inner cavity of the storage compartment 3, two front and rear ballast compartments 5 being provided inside the ballast tank 1 and located outside the storage compartment 3, two left and right balancing assemblies 6 being provided inside each ballast compartment 5, a water pump 7 being installed in the middle of each ballast compartment 5 and penetrating the ballast tank 1, and evenly distributed auxiliary balancing support frames 8 being installed at the bottom of the ballast tank 1;

[0028] As the water pump 7 continuously pumps water, the increase in the amount of water inside the ballast tank 5 causes the first sealing sleeve 67 and the third sliding sleeve 66, or the second sealing sleeve 68 and the second sliding sleeve 65, to move downward as a whole, subject to the restriction of the return spring 64. When the third sliding sleeve 66 or the second sliding sleeve 65 moves to the lowest point relative to the second sliding sleeve 65, the first sliding sleeve 61 is pressed downward by the continuously increasing water pressure, causing it to move downward and compressing the return spring 64 via the stopper 63. As the first sealing sleeve 67 and the third sliding sleeve 66 or the second sealing sleeve 68 and the second sliding sleeve 65 or the first sliding sleeve 61 move downward, the water storage capacity of the balancing assembly 6 is gradually increased, and the overall length of the balancing assembly 6 is increased, thereby increasing the lateral water resistance of the entire equipment through the evenly distributed balancing assembly 6.

[0029] The symmetrically arranged ballast tank 5, balance assembly 6 and auxiliary balance support frame 8 can improve the stability of the overall center of the equipment, thereby improving the stability of the equipment itself. The balance assembly 6, whose specifications can be freely adjusted according to the increase or decrease of the water volume inside the ballast tank 5, can not only improve the overall water storage capacity of the ballast tank, so that it can dive deeper, but also the increased balance assembly 6 can extend to the bottom of the ballast tank 1, thereby increasing its lateral water resistance, thereby reducing the intensity of impact shaking and further improving stability.

[0030] Among them, a guardrail 9 is fixedly installed on the top of the delivery bin 2, and the bottom of the guardrail 9 is hinged with two left and right sealing plates 10 embedded in the interior of the delivery bin 2. The sealing plates 10 are semicircular, and the arc surfaces of the two sealing plates 10 are in contact with the inner wall of the delivery bin 2, and the facing surfaces of the two sealing plates 10 are in contact with each other;

[0031] The guardrail 9 allows the trainees who enter the delivery bin to observe the external environment at all times so as to better conduct danger simulation training. The sealing plate 10 can be used to close the top of the delivery bin 2 in cooperation with the guardrail 9 to achieve an enclosed space, thereby facilitating a better rest for the trainees.

[0032] Among them, the top of the ballast tank 1 is provided with a rest chamber 11 located inside the delivery chamber 2, and the interior of the storage chamber 3 is provided with a filter plate 12 located on the top of the drainage chamber 4;

[0033] The interiors of the drainage tank 4 and the ballast tank 5 are connected to each other through a pump embedded in the ballast tank 1. Then, after closing the two sealing plates 10 and the sealing cover 14, a sealed space is formed in the storage tank 3 and the rest tank 11 areas inside the delivery tank 2 equipment. Then, under the action of the pump, the water inside the storage tank 3 and the delivery tank 2 can be discharged, so that the training personnel can rest better in the rest tank 11 to restore their physical strength.

[0034] Among them, two left and right escape passages 13 are opened on the side of the delivery bin 2, and the escape passages 13 connect the inside and outside of the delivery bin 2. Two left and right sealing covers 14 are hinged inside the delivery bin 2, and the sealing covers 14 completely seal and cover the ends of the escape passages 13;

[0035] The escape passage 13 allows trainees to enter the rest compartment 11 to access supplies inside the storage compartment 3, and also allows them to escape from simulated underwater dangers, thereby improving the authenticity of the training. The sealing cover 14 can separate the inside and outside of the delivery compartment 2 to better escape danger, while also ensuring that the interior of the delivery compartment 2 is sealed.

[0036] A winch 15 is installed on the top of the rest cabin 11, and the winch 15 is connected to a floating rope assembly 16 located above the guardrail 9 through a rope wound around the surface;

[0037] The required materials can be prepared in advance through the storage bin 3, and the floating rope assembly 16 can cooperate with the winch 15 to make the upper end of the rope float to the water surface. Then, the cooperation between the winch 15 and the rope facilitates the replenishment of materials for the delivery equipment itself during training, thereby improving the practicality of the delivery equipment.

[0038] The balancing assembly 6 includes a first sleeve 61 disposed inside the ballast tank 5. The lower end of the outer surface of the first sleeve 61 extends to the bottom of the ballast tank 1 and is fixedly connected to an anti-drop block 62. The upper end of the outer surface of the first sleeve 61 is fixedly sleeved with a stopper 63. A return spring 64 is provided on the outside of the first sleeve 61 and is located at the bottom of the stopper 63. The lower end of the return spring 64 abuts against the inner wall of the ballast tank 5.

[0039] Due to the increase in the amount of water inside the ballast tank 5, the downward movement of the first sealing sleeve 67 and the third sliding sleeve 66 or the second sealing sleeve 68 and the second sliding sleeve 65 or the first sliding sleeve 61 will gradually increase the overall length of the balancing assembly 6, thereby increasing the overall water storage capacity of the balancing assembly 6. The evenly distributed balancing assembly 6 improves the overall lateral stability of the equipment and reduces the intensity of the overall shaking of the equipment.

[0040] Among them, the internal sliding clamp of the first sliding sleeve 61 is connected to the second sliding sleeve 65, the internal sliding clamp of the second sliding sleeve 65 is connected to the third sliding sleeve 66, the top of the second sliding sleeve 65 is fixedly connected to the second sealing sleeve 68 which is sealed and connected to the inside of the first sliding sleeve 61, the top of the third sliding sleeve 66 is fixedly connected to the first sealing sleeve 67 which is sealed and connected to the inside of the second sealing sleeve 68, the tops of the first sealing sleeve 67 and the second sealing sleeve 68 are abutted against the top of the inner cavity of the ballast tank 5, and the tops of the first sealing sleeve 67 and the second sealing sleeve 68 are both provided with water inlet grooves 69.

[0041] The floating rope assembly 16 includes a floating block 161 located above the guardrail 9. The bottom of the floating block 161 is fixedly connected to a magnetic block 162. The interior of the magnetic block 162 is fixedly sleeved with a threaded sleeve 163. The interior of the threaded sleeve 163 is threadedly sleeved with a connecting shaft 164. The bottom of the connecting shaft 164 is connected to a rope wrapped around the surface of the winch 15.

[0042] Under the buoyancy of the float 161, the upper end of the rope can be lifted through the cooperation of the magnetic block 162, the threaded sleeve 163, the connecting shaft 164 and the winch 15, so that it can float to the water surface. By unscrewing the connecting shaft 164 from the inside of the threaded sleeve 163, the rope and the float 161 can be separated, and the rope can be retracted into the inside of the delivery bin 2 to facilitate closing the two sealing plates 10. The separated float 161 and threaded sleeve 163 are adsorbed on the top of the guardrail 9 through the fixedly connected magnetic block 162.

[0043] Among them, the outer diameter of the connecting shaft 164 is smaller than the gap inside the guardrail 9, and the connecting shaft 164 moves to the bottom of the guardrail 9 following the rope. The adsorption strength between the magnetic block 162 and the guardrail 9 is greater than the buoyancy strength of the floating block 161.

[0044] The working principle and use process of the present invention:

[0045] When the water pump 7 is turned on and continuously pumps water, the increase in the water volume within the ballast tank 5 causes the first sealing sleeve 67 and the third sliding sleeve 66, or the second sealing sleeve 68 and the second sliding sleeve 65, to move downward as a whole, under the restriction of the return spring 64. When the third sliding sleeve 66 or the second sliding sleeve 65 moves to the lowest point relative to the second sliding sleeve 65, the first sliding sleeve 61 is pressed downward by the continuously increasing water pressure, causing it to move downward and compress the return spring 64 via the stopper 63. As the first sealing sleeve 67 and the third sliding sleeve 66 or the second sealing sleeve 68 and the second sliding sleeve 65 or the first sliding sleeve 61 move downward, the water storage capacity of the balancing assembly 6 is gradually increased, and the overall length of the balancing assembly 6 is increased. This improves the overall lateral stability of the equipment through the evenly distributed balancing assembly 6.

[0046] Closing the sealing plate 10 and the sealing cover 14 forms a sealed space inside the delivery chamber 2 and the storage chamber 3, allowing the trainees to rest and adjust in the rest chamber 11. During the danger simulation training, the trainees can return to the interior of the delivery chamber 2 through the escape passage 13. Then closing the sealing cover 14 can block the external simulated dangerous objects, making the training more realistic.

[0047] The water pump 7 pumps water into the ballast tank 5 to make the entire equipment dive to the depth required for training. During training, if materials need to be delivered, the winch 15 can be turned on to rotate it and the rope can be reeled out, and then the telescopic upper end can float to the water surface under the buoyancy of the floating rope assembly 16. After the materials are bundled, the pneumatic winch 15 rotates in the opposite direction to pull the materials to the top of the guardrail 9 by contraction. The materials can then be removed by the trainees below for use or placed in the storage bin 3.
