[0019] like Figure 1 As shown, a vertical icebreaking test device for an underwater vehicle provided by the present invention includes a water pool 100 and a traveling assembly 200, wherein the water pool 100 has a first pool body 110 and two second pool bodies 120 located on both sides of the first pool body 110, and a channel 130 connecting the bottom of the first pool body 110 and the bottom of the second pool body 120 is formed inside the water pool 100; the traveling assembly 200 includes a bearing plate 210 and two connecting brackets 220, the bearing plate 210 is arranged in the first pool body 110, the two connecting brackets 220 are arranged in the second pool body 120, the opposite sides of the two connecting brackets 220 are connected to the bearing plate 210, and the two connecting brackets 220 pass through to the outside of the second pool body 120 and are slidably connected to the top surface of the water pool 100.

[0020] During implementation, the submersible is placed on the supporting plate 210 located in the first tank body 110, so that the water in the first tank body 110 freezes, while the water in the second tank body 120 does not freeze. One side of the connecting bracket 220 located in the second tank body 120 is connected to the supporting plate 210, and the other side of the connecting bracket 220 is a sliding structure. The sliding structure passes through the top of the second tank body 120, and its sliding connection part is located on the top surface of the water pool 100. There is no transmission or sliding structure in the water pool 100. Therefore, the movement of the submersible is not affected by ice, and the sliding structure is located on the water surface for easy maintenance.

[0021] The water pool 100 in this embodiment comprises a first pool body 110 and two second pool bodies 120 located on both sides of the first pool body 110 . A channel 130 is formed inside the water pool 100 to connect the bottom of the first pool body 110 with the bottom of the second pool body 120 .

[0022] Among them, ice can be made in the first pool body 110 through a cooling refrigerator, and an ice layer is formed on the water surface of the first pool body 110. The submersible is placed in the first pool body 110 in advance. After the submersible floats up, it interacts with the ice layer, thereby simulating and studying the vertical icebreaking process of the submersible.

[0023] In order to form the above-mentioned first pool body 110 and the two second pool bodies 120, in one embodiment, the underwater vehicle vertical icebreaking test device also includes two vertically arranged partitions 140, the two partitions 140 are arranged in parallel and fixedly connected to the water pool 100, the first pool body 110 is formed between the two partitions 140, the two second pool bodies 120 are formed between the opposite sides of the two partitions 140 and the water pool 100, and a channel 130 is formed between the bottom of the two partitions 140 and the bottom of the water pool 100.

[0024] The traveling assembly 200 in this embodiment is a structure that carries the submersible and drives the submersible to move in the pool 100. Since the pool 100 is usually long, multiple vertical icebreaking experiments can be performed along the length direction of the first pool body 110. The traveling assembly 200 can drive the submersible to move along the length direction of the first pool body 110, thereby achieving multiple vertical icebreaking operations.

[0025] The traveling assembly 200 in this embodiment includes a supporting plate 210 and two connecting brackets 220. The supporting plate 210 is arranged in the first pool body 110, and the two connecting brackets 220 are arranged in the second pool body 120. The opposite sides of the two connecting brackets 220 are connected to the supporting plate 210, and the two connecting brackets 220 extend out of the second pool body 120 and are slidably connected to the top surface of the water pool 100.

[0026] In one embodiment, the bearing plate 210 is used to support the submersible, and its top is a plane, so as to facilitate the stable placement of the submersible. It is understandable that a groove for stabilizing the submersible and limiting the position of the submersible can also be provided on the bearing plate 210, so that the bracket at the bottom of the submersible can be embedded in the groove, that is, in this embodiment, the shape and structure of the bearing plate 210 are not limited, and stable placement is preferred.

[0027] In one embodiment, the connecting bracket includes a connecting slider 221 and a connecting rod 222, the connecting slider 221 is slidably connected to a slide rail 223 installed on the top of the pool 100, the top of the connecting rod 222 is fixedly connected to the connecting slider 221, and the bottom end of the connecting rod 222 extends into the second pool body 120 and passes through the channel 130 to be connected to the supporting plate 210.

[0028] The connecting slider 221 is disposed on the water surface, and is slidably connected to the top surface of the pool 100 via a slide rail 223 . The connecting rod 222 is a rod structure connecting the slider 221 and the supporting plate 210 .

[0029] In order to limit the stability of the supporting plate's moving direction, in one embodiment, a slide groove 141 is provided at the bottom of the partition 140 , and a guide slider is fixedly connected to the supporting plate 210 or the connecting bracket 220 , and the guide slider is slidably connected to the slide groove 141 .

[0030] Among them, both sides of the supporting plate 210 can extend through the channel 130 to the second cell body 120 and connect to the connecting bracket, or the opposite sides of the two second brackets can extend through the channel 130 to the first cell body 110. Both methods can realize the invention intent in this embodiment.

[0031] The connecting bracket 220 can be pushed to slide on the guide rail by manpower. To save effort, the connecting bracket 220 can be driven to slide by a driving structure. In one embodiment, the traveling component 200 also includes a driving member 230, which is installed on the top surface of the pool 100. The output end of the driving member 230 is connected to the two connecting brackets 220, and is used to drive the two connecting brackets to slide along the length direction of the pool 100.

[0032] The driving member 230 includes two screw rods 231, a motor 232, two gears 233, a chain 234 and a plurality of bearing seats 235. The two screw rods 231 are installed on the pool 100 via the plurality of bearing seats 235. The two screw rods 231 are connected to the threaded holes 224 provided on the two connecting sliders 221. The motor 232 is fixedly connected to the pool 100. The output end of the motor 232 is connected to one of the screw rods 231. The two gears 233 are respectively sleeved on the two screw rods 231. The chain 234 is transmission-connected to the two gears 233. It is understandable that the driving member 230 can also be replaced by a structure such as an oil cylinder.

[0033] In one embodiment, the submersible's own buoyancy function can be used to achieve vertical icebreaking, which can be achieved by introducing gas into or exhausting gas from the submersible, or by changing the weight of the submersible. This is a conventional way that technicians in this field can think of to control the ascent and descent of a submersible.

[0034] In another embodiment, the traveling assembly 200 further includes a lifting platform 240 installed on the bearing plate 210 and located in the first pool body 110, and the top of the lifting platform 240 has a mounting surface for placing the submersible. The submersible located on the lifting platform 240 can be driven to move upward by the vertical movement of the lifting platform 240 until vertical ice breaking is achieved.

[0035] The lifting platform 240 includes a plurality of lifting cylinders and a lifting plate, wherein the plurality of lifting cylinders are mounted on the bearing plate 210, and the output ends of the plurality of lifting cylinders are connected to the lifting plate. It is understood that the wires connected to the lifting cylinders can be attached to the bearing plate 210 and the connecting bracket 220 to extend outside the pool 100 and be connected to a power source.

[0036] To prevent the water surface of the second pool body 120 from freezing and affecting the movement of the connecting bracket 220, Figure 2 As shown, the present embodiment further includes an antifreeze component 300, which has an antifreeze end, which is connected to the water surface of the second pool body 120 and is used to drive the water on the water surface of the second pool body 120 to flow. It can be understood that flowing water is less likely to freeze than static water. Therefore, the present application uses the antifreeze component 300 to make the water on the water surface of the second pool body 120 flow, thereby preventing the water surface of the second pool body 120 from freezing, wherein the flow of the water on the water surface of the second pool body 120 does not affect the static state of the water surface of the first pool 100, that is, it does not affect the freezing process of the water surface of the first pool 100.

[0037] In one embodiment, the antifreeze assembly 300 includes a water pump 310, a water inlet pipe 320, a water outlet pipe 330 and a cross pipe 340. The water pump 310 is installed on the side wall of the water pool 100. The water inlet end of the water pump 310 is connected to the second pool body 120 via the water inlet pipe 320, and the water outlet end of the water pump 310 is connected to the cross pipe 340 via the water outlet pipe 330. The cross pipe 340 is fixedly arranged at a position close to the water surface in the second pool body 120 along the extension direction of the second pool body 120, and the cross pipe 340 is provided with multiple water outlet holes facing the water surface in the second pool body 120.

[0038] like Figure 3 As shown, in order to prevent the portion of the traveling assembly 200 located at the channel 130 from freezing, in one embodiment, a drainage groove 142 is provided at the portion of the pool 100 located above the channel 130, and the drainage groove 142 is connected to the water inlet end pipe.

[0039] To avoid ice formation between the guide slider and the partition 140, in one embodiment, the drainage groove 142 is connected to the slide groove 141 to allow water near the guide slider to flow, thereby avoiding ice formation and ensuring stable sliding of the guide slider.

[0040] Compared with the prior art: the submersible is placed on a supporting plate 210 located in the first tank body 110, so that the water in the first tank body 110 freezes, while the water in the second tank body 120 does not freeze, and one side of the connecting bracket 220 located in the second tank body 120 is connected to the supporting plate 210, and the other side of the connecting bracket 220 is a sliding structure, which passes through the top of the second tank body 120, and its sliding connection part is located on the top surface of the water pool 100. There is no transmission or sliding structure in the water pool 100. Therefore, the movement of the submersible is not affected by ice, and the sliding structure is located on the water surface, which is easy to maintain.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
