Description

Technical Field

[0001] The utility model relates to the technical field of unmanned boats, in particular to an unmanned boat wind brake. Background Art

[0002] At present, unmanned remote control technology is developing rapidly, and unmanned boats are being used more and more widely in the fields of maritime rescue, scientific research and exploration, security patrols, special missions, etc.

[0003] During the voyage of ships at sea, the marine environment is unpredictable. Once its severity exceeds the range of normal operation of the boat, it will pose a huge threat to the safety of life and property of the boat, equipment and crew members. Therefore, some unmanned boats, pilot boats, lifeboats, and law enforcement boats are equipped with self-righting devices to prevent the boat from completely capsizing and endangering the safety of personnel and high-value equipment. At this time, the air inlet and outlet of the engine room will become high-risk water ingress points. Once the engine room is seriously flooded and the buoyancy volume is excessively reduced, even if the self-righting device is fully inflated, it will not have sufficient heel recovery torque to automatically right the boat. Even if the degree of water ingress in the engine room does not ultimately prevent the boat from self-righting, important equipment in the engine room is still at risk of being damaged by water.

[0004] At present, ship engine room ventilation is usually divided into natural ventilation and mechanical ventilation, such as Figure 4 As shown, ventilation grilles or ventilators are installed on both sides of the ship, and the ventilation grilles or ventilators are equipped with a mechanical closing system. There are some inevitable problems when installing this system on an unmanned boat:

[0005] 1. The unmanned boat does not have the conditions for the crew to manually close the ventilation device;

[0006] 2. In special situations such as when the unmanned boat floods from the mother ship or when the sea conditions are high, the vents on both sides of the ship will have a higher risk of water ingress;

[0007] 3. If the boat is equipped with a trigger-type self-righting device, the wind brake will continue to be exposed to the risk of water ingress during the period from when the boat's tilt angle exceeds the sensor trigger value to when the self-righting airbag is inflated (approximately 30 seconds). Utility Model Content

[0008] In view of the deficiencies in the prior art, the utility model provides an automatic opening and closing damper for an engine room of an unmanned boat, which solves the problem that the prior damper is inconvenient and untimely to close.

[0009] The purpose of the utility model is achieved as follows: an automatic opening and closing wind gate for an unmanned boat cabin comprises a wind gate body, a plurality of gate plates are arranged in the wind gate body, the gate plates are mounted on the wind gate body via a driving shaft and a driven shaft, both ends of the driving shaft and the driven shaft are rotatably mounted on the wind gate body, the driving shaft is transmission-connected to the driven shaft, and the driving shaft is transmission-connected to the output shaft of an electric actuator.

[0010] Furthermore, a driving gear is provided at one end of the driving shaft, and a driven gear is provided at one end of the driven shaft corresponding to the driving shaft, and the driving gear is meshed with the driven gear.

[0011] Furthermore, a plurality of driven shafts are provided and are evenly distributed along the length direction of the wind damper body, and adjacent driven shafts are meshed with each other via driven gears.

[0012] Furthermore, the wind damper body comprises a square frame, and a flange edge is provided at the bottom of the square frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the device of the utility model is simple to manufacture, and different vent sizes can be designed according to different installation positions; once the unmanned boat is in danger of capsizing in high sea conditions, the self-righting device can be linked to the utility model to automatically control the closing of the vent, which greatly reduces the possibility of water entering the engine room and improves the safety of the ship.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3 The shown embodiment is an automatic opening and closing wind gate for an unmanned boat cabin, comprising a wind gate body 100, in which a plurality of gate plates 200 are arranged, the gate plates 200 are mounted on the wind gate body 100 via a driving shaft 300 and a driven shaft 400, the two ends of the driving shaft 300 and the driven shaft 400 are rotatably mounted on the wind gate body 100, the driving shaft 300 is transmission-connected to the driven shaft 400, and the driving shaft 300 is transmission-connected to the output shaft of the electric actuator 700.

[0022] Specifically, the gate plate 200 is composed of two half plates 201 installed on the driving shaft 300 and the driven shaft 400, and the electric actuator 700 adopts a driving motor.

[0023] It should be noted that the device is installed at the air inlet and outlet of the unmanned boat, and the electric actuator 700 is electrically connected to the self-righting device of the unmanned boat (not shown in the figure, which is a prior art and is installed on the unmanned boat) to receive its sensor signal. When the electric actuator 700 receives the sensor signal, it controls the driving shaft 300 to rotate, and the driving shaft 300 drives the driven shaft to rotate, thereby flipping the gate plate 200 and closing the wind brake body 100.

[0024] Furthermore, a driving gear 500 is disposed at one end of the driving shaft 300 , and a driven gear 600 is disposed at one end of the driven shaft 400 corresponding to the driving shaft 300 , and the driving gear 500 is meshed with the driven gear 600 .

[0025] Specifically, a driving gear 500 and a driven gear 600 may be provided at the other end of the driving shaft 300 and the other end of the driven shaft 400, and mesh with each other; such a design can further enhance the reliability of the transmission.

[0026] Furthermore, a plurality of driven shafts 400 are provided, which are evenly distributed along the length direction of the damper body 100 , and adjacent driven shafts 400 are meshed with each other via driven gears 600 .

[0027] It should be noted that if the air inlet and outlet are long and you want to close the air inlet and outlet through a single driving shaft 300 and a driven shaft 400, you need to increase the size of the gate plate 200. Due to the height limitation of the wind damper body 100, the gate plate 200 will become bulky. Therefore, a plurality of mutually meshing driven shafts 400 are designed to cooperate with the gate plate 200 of the original size to achieve the opening and closing of the long air inlet and outlet.

[0028] Furthermore, the damper body 100 includes a square frame 101 , and a flange 102 is provided at the bottom of the square frame 101 .

[0029] It should be noted that the design of the flange 102 facilitates the installation of the device.

[0030] The utility model is further described below in conjunction with the principle.

[0031] If an unmanned boat encounters high sea conditions or collisions, it may shake violently or even capsize. If it is equipped with a trigger-type self-righting device, it must be ensured that it will not lose its automatic righting ability due to water entering the wind gate during the capsizing and inflation process. Since the cabin ventilation wind gate must be manually closed by the ground remote control station operator, it cannot ensure safety. If there is no ventilation wind gate, additional cabin cooling equipment must be installed, which increases weight and cost. Therefore, designing a stable and reliable automatic switch type inlet and outlet wind gate can solve this problem.

[0032] The working principle of the utility model is as follows:

[0033] 1. When the attitude sensor of the ship's self-righting device detects that the boat's tilt angle exceeds 120°, the sensor will send a switch signal;

[0034] 2. The intermediate relay of the gas cylinder solenoid valve controlled by the switch signal of the sensor controls the filling action of the gas cylinder;

[0035] 3. The intermediate relay of the drive motor controlled by the switch signal of the sensor controls the reverse rotation of the drive motor;

[0036] 4. After the driving motor starts working, it drives the wind brake driving shaft 300 to rotate;

[0037] 5. A transmission gear (driving gear 500 and driven gear 600) is arranged between the wind brake driving shaft 300 and the driven shaft 400, so as to achieve the overall follow-up and close the gate;

[0038] 6. When the ship is turned over and righted by the self-righting device and the tilt angle returns to the normal range, the sensor stops sending switch signals;

[0039] 7. After the drive motor actuator loses the attitude sensor signal, the drive motor rotates forward;

[0040] 8. The wind brake driving shaft 300 and the driven shaft 400 realize the opening of the gate by overall following movement.

[0041] During specific use, different sizes of wind gate bodies are customized according to the sizes of ventilation holes of different ship types; the wind gate body can be welded or bolted to the hull; after installation, a flushing test is carried out, the outlet pressure is not less than 0.2MPa, the inner diameter of the nozzle is not less than 12.5mm, the distance between the nozzle and the test point is not more than 1.5m, the water column moving speed is not more than 0.1m / s, and the motor torque is 2000 N•m, i.e. 0.2MP, which meets the watertight requirements.

[0042] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
