Description

Technical Field

[0001] The utility model belongs to the technical field related to underwater submarines, and particularly relates to an automatic balancing device for traveling in underground rivers. Background Art

[0002] The device should have a streamlined appearance to reduce water flow resistance. An electric thruster is selected, which can propel the device through spiral jet. At the same time, ensure that the volume of the device is suitable for moving in underground rivers. Maintain stability by draining or injecting water to prevent capsizing in areas with strong water flow. An built-in gyroscope sensor can monitor the tilt angle of the device in real time and adjust the center of gravity at any time to keep it horizontal. Keep it at any depth in the water body without floating or sinking. However, when the balancing device is about to lose power in the water body and the remaining power is not enough to lift the balancing device to the water surface, the balancing device can only sink in the water body, resulting in the balancing device moving with the surging in the underground river water. And after power off, the signal gradually weakens until it cannot be transmitted, resulting in the loss of the balancing device and being not easy to retrieve. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic balancing device for traveling in underground rivers, so as to solve the problem that when the balancing device is about to lose power in the water body and the remaining power is not enough to lift the balancing device to the water surface as mentioned in the above background art.

[0017] By installing the airbag and the counterweight, when using the balancing device, the buoyancy of the airbag and the gravity of the counterweight balance each other, enabling the fuselage to float on the water surface, and the airbag is underwater. When water is gradually added to the water tank, the weight of the balancing device gradually becomes greater than the buoyancy provided by the airbag, and at this time, the balancing device sinks. When the battery power inside the fuselage is insufficient to make the balancing device float, the last bit of power can be used to drain the water in the water tank. At this time, the buoyancy in the airbag is greater than the weight of the balancing device, and the balancing device is floated to the water surface by the airbag. At this time, the staff can directly observe the position of the balancing device on the water surface of the underground river, which is convenient for subsequent salvage, avoiding the situation of sinking to the bottom of the underground river due to power failure and salvaging relying on weak signals, and increasing the probability of successful salvage.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides an automatic balancing device traveling in an underground dark river as Figures 1-4 shown, including a fuselage 1 and a gyroscope 7 installed inside the fuselage 1;

[0025] A thruster 8 is provided on the outer wall of the right end of the fuselage 1 to push the balancing device to move in the water;

[0026] A water tank 11 is fixedly connected to the outer wall of the lower end of the fuselage 1;

[0027] Drain valves 10 are respectively provided on the outer wall of the front end of the water tank 11 and close to both the left and right sides to control the entry and exit of the liquid in the water tank 11. When using the balancing device, first fill the water tank 11 with water, turn on the gyroscope 7, continuously monitor the attitude of the device through the gyroscope 7, and control the volume of the liquid in the water tank 11 by controlling the direction of the thruster 8 and the drain valve 10 of the water tank 11 to maintain the stability of the device;

[0028] An airbag 14 is provided below the water tank 11 for upward buoyancy, and a counterweight 15 is provided below the airbag 14 to press the airbag 14 below the water surface when the balancing device is on the water surface. When the power of the balancing device is insufficient to support the device to float to the water surface, it can be remotely controlled to drain the remaining water in the water tank 11. At this time, the buoyancy of the airbag 14 is greater than the weight of the balancing device, and the balancing device can be lifted and floated on the water surface to avoid the situation that the balancing device sinks to the bottom due to power failure. After the balancing device is lifted to the water surface, the weight of the counterweight 15 makes the airbag 14 not float on the water surface, so that the position of the airbag 14 is below the water surface of the underground river.

[0029] As Figure 3 and Figure 4As shown in the figure, a fixed frame 12 is fixedly connected to the outer wall of the lower end of the water tank 11 to limit the positions of the airbag 14 and the counterweight 15. A bottom plate 13 is arranged on the lower side of the fixed frame 12. A plurality of downwardly opening grooves 16 are formed in the outer wall of the lower end of the fixed frame 12. A buffer spring 17 is fixedly connected between the inner walls of the upper ends of the plurality of grooves 16 and the bottom plate 13.

[0030] The positions among the airbag 14, the counterweight 15 and the water tank 11 are restricted by the fixed frame 12. When the balancing device touches the bottom, the bottom plate 13 can contact the bottom of the underground river, and the buffer spring 17 contracts for buffering. If the impact during falling is large, it will rebound to avoid damage.

[0031] As Figure 3 and Figure 4 shown in the figure, the gravity provided by the counterweight 15 is less than the buoyancy provided by the airbag 14. The fixed frame 12 is designed to be sealed and fixedly connected to the water tank 11 by welding.

[0032] The gravity of the counterweight 15 is less than the buoyancy of the airbag 14. When adding the gravity of the balancing device, it is slightly greater than the buoyancy provided by the airbag 14. At this time, the airbag 14 is located below the water surface, and the fuselage 1 is located above the water surface, which is convenient for the front drain valve 10 of the water tank 11 to intake water.

[0033] As Figure 1 and Figure 2 shown in the figure, a control module 4 is fixedly connected to the inner wall of the left end of the fuselage 1. A signal transmitter 2 is embedded in the outer wall of the front end of the control module 4 to send information signals to the outside. A signal detector 3 is embedded inside the outer wall of the left end of the fuselage 1 to detect the undercurrent in the underground river. Spiral elevators 9 are fixedly connected to the outer walls of the upper and lower ends of the fuselage 1 and are respectively close to the left and right sides to drive the balancing device to move up and down in the underground river.

[0034] The direction of the undercurrent and obstacles such as stones in the underground river can be detected by the signal detector 3. When the fuselage 1 moves, instructions can be sent through the signal detector 3 to avoid undercurrent obstacles. At the same time, the spiral elevators 9 can also be controlled to rotate in different directions to keep the balance of the fuselage 1. After the data detected by the signal detector 3 is processed by the control module 4, the detected data can also be sent to the user terminal through the signal transmitter 2 for remote viewing.

[0035] As Figure 1 and Figure 2 shown in the figure, drivers 5 are respectively arranged on the inner sides of the fuselage 1 close to the left and right sides to control the operation of the thrusters 8 and the spiral elevators 9. A battery 6 is arranged inside the fuselage 1 to supply power to the drivers 5. The plurality of spiral elevators 9 are separately controlled and can rotate clockwise or counterclockwise. A fixed seat is arranged on the outer wall of the rear end of the gyroscope 7 to limit the position of the gyroscope 7.

[0036] After the signal detection head 3 detects data, it can drive the thruster 8 and the screw lifter 9 through the control driver 5 to execute different instructions for work to maintain the balance of the fuselage 1, and the battery 6 supplies power to the driver 5, the control module 4 and the drain valve 10 so that they can work normally.

[0037] The implementation principle of this embodiment is as follows: When using the balancing device, first fill the water tank 11 with water, turn on the gyroscope 7, continuously monitor the attitude of the device through the gyroscope 7, and control the volume of the liquid in the water tank 11 by controlling the direction of the thruster 8 and the drain valve 10 of the water tank 11 to maintain the stability of the device. When the power of the balancing device is not enough to support the device to float to the water surface, it can be remotely controlled to drain the remaining water in the water tank 11. At this time, the buoyancy of the airbag 14 is greater than the weight of the balancing device, so the balancing device can be lifted and floated on the water surface to avoid the situation that the balancing device sinks to the bottom due to power failure. After the balancing device floats to the water surface, the weight of the counterweight 15 makes the airbag 14 not float on the water surface, so that the position of the airbag 14 is under the water surface of the underground river.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
