Description

Technical Field

[0001] The utility model relates to the technical field of hovercrafts, and relates to an anti - rollover device for hovercrafts. Background Art

[0002] A hovercraft is a high - speed ship that utilizes the surface effect principle and relies on air above atmospheric pressure to form an air cushion between the hull and the support surface, enabling the hull to sail completely or partially off the support surface;

[0003] Currently, during the operation of a hovercraft on water, encountering wind and waves as well as turning at an angle will easily cause the hovercraft to roll over. Generally, a power device, a fan, is equipped on the hovercraft. After the hovercraft rolls over, people are likely to come into contact with the fan blades in a panic in the water, thus increasing the risk of human injury;

[0004] To solve the above problems, an anti - rollover device for hovercrafts is proposed in this application. Content of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art and provides an anti - rollover device for hovercrafts.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: an anti - rollover device for hovercrafts, including an anti - rollover structure, and the anti - rollover structure is arranged on the hull;

[0007] The anti - rollover structure includes two square tubes installed at the bottom of the hull, a mounting shell detachably installed on the top of the hull, and two air pumps located above the hull. The output ends of the two air pumps are both equipped with air outlet pipes. The ends of the two air outlet pipes far from the corresponding air pumps are respectively communicated with the corresponding square tubes, and a plurality of nozzles are installed on both square tubes;

[0008] Two arc - shaped openings are penetrated through the mounting shell. The mounting shell is movably inserted with threaded rods through the two arc - shaped openings. One ends of the two threaded rods are both equipped with moving blocks, and contact switches are installed on both moving blocks. Nuts are threadedly connected to both threaded rods. A rotating needle is rotatably connected to the inner wall of the mounting shell, and the two contact switches are respectively electrically connected to the corresponding air pumps;

[0009] A lubrication structure is arranged on the mounting shell.

[0010] Bolts are installed on the mounting shell, and the mounting shell is installed on the hull through the bolts. By setting the bolts, it is convenient to disassemble and assemble the mounting shell.

[0011] A bracket is installed on the top of the hull, and both air pumps are installed on the bracket. By setting the bracket, it is used to support and fix the two air pumps.

[0012] A support rod is installed on the inner wall of the mounting shell, the rotating needle is movably sleeved on the outer side of the support rod, and a limiting plate is installed on one end of the support rod. The support rod and the limiting plate are provided to support and limit the rotating needle.

[0013] The lubrication structure includes a connecting hole opened on the top of the mounting shell, and the mounting shell is connected to a lubrication box through the connecting hole. The connecting hole is located directly above the rotating needle, and a lubrication port is opened on the rotating needle. The lubrication structure is provided to lubricate the pointer.

[0014] The mounting shell is provided with a sponge rod through the connecting hole, and the flow rate of the lubricating liquid is slowed down by arranging the sponge rod.

[0015] The beneficial effects of the utility model are:

[0016] By setting up an anti-rollover structure and adjusting the position of the contact switch, the anti-rollover structure itself is calibrated. When the driver turns, the contact switch tilts with the hull, and the rotating needle is perpendicular to the water surface due to its own weight. When the contact switch touches the rotating needle, the air pump on one side of the contact switch is started, so that the air is quickly injected into the square tube through the air outlet pipe, and finally quickly ejected through the nozzle, so as to coordinate the hull and try to avoid rollover;

[0017] By setting up a lubrication structure, the lubricating liquid is poured into the lubrication box. The lubricating liquid first soaks the sponge rod, and the sponge rod decelerates the lubricating liquid, so that the lubricating liquid component drips into the lubrication port to lubricate the rotating needle and ensure the sensitivity of the rotating needle as much as possible.

[0031] Refer to Figures 1-5, An anti - rollover device for an air - cushion vehicle, including an anti - rollover structure 2. The anti - rollover structure 2 is arranged on the hull 1. The anti - rollover structure 2 includes two square tubes 214 installed at the bottom of the hull 1, a mounting shell 201 detachably installed on the top of the hull 1, and two air pumps 212 located above the hull 1. The output ends of the two air pumps 212 are both installed with air outlet pipes 213. The ends of the two air outlet pipes 213 far from the corresponding air pumps 212 are respectively communicated with the corresponding square tubes 214. A plurality of nozzles 215 are installed on the two square tubes 214. Two arc - shaped openings 206 are penetrated through the mounting shell 201. The mounting shell 201 is movably inserted with threaded rods 207 through the two arc - shaped openings 206. One ends of the two threaded rods 207 are both installed with moving blocks 209. Contact switches 210 are installed on the two moving blocks 209. Nuts 208 are threadedly connected to the two threaded rods 207. A rotating needle 204 is rotatably connected to the inner wall of the mounting shell 201. The two contact switches 210 are respectively electrically connected to the corresponding air pumps 212. According to the above - mentioned technical solution, it should be noted that by adjusting the position of the contact switch 210, the angle that the rotating needle 204 can rotate is changed to achieve the purpose of better calibration;

[0032] According to the above - mentioned technical solution, specifically, when the driver turns, the contact switch 210 tilts along with the hull 1, while the rotating needle 204 is perpendicular to the water surface due to its own weight. When the contact switch 210 touches the rotating needle 204, the air pump 212 on one side of the contact switch 210 is started, so that it quickly injects air into the square tube 214 through the air outlet pipe 213 and finally sprays it out quickly through the nozzles 215, thereby coordinating the hull 1 to avoid rollover as much as possible.

[0033] Refer to Figure 1 , Bolts 202 are installed on the mounting shell 201. The mounting shell 201 is installed on the hull 1 through the bolts 202. The bolts 202 facilitate the disassembly and assembly of the mounting shell 201.

[0034] A bracket 211 is installed on the top of the hull 1. The two air pumps 212 are both installed on the bracket 211. The bracket 211 is used to support and fix the two air pumps 212.

[0035] Refer to Figure 6 , A support rod 203 is installed on the inner wall of the mounting shell 201. The rotating needle 204 is movably sleeved on the outside of the support rod 203. A limiting plate 205 is installed at one end of the support rod 203. The support rod 203 is used to support the rotating needle 204, and the limiting plate 205 is used to prevent the rotating needle 204 from detaching from the support rod 203 as much as possible.

[0036] Refer to Figure 6, a lubrication structure 3 is provided on the installation shell 201. The lubrication structure 3 includes a communication hole 302 opened at the top of the installation shell 201. The installation shell 201 is communicatively installed with a lubrication tank 301 through the communication hole 302. The communication hole 302 is located directly above the rotating needle 204. A lubrication port 304 is opened on the rotating needle 204. The installation shell 201 is installed with a sponge rod 303 through the communication hole 302. Among them, the sponge rod 303 is used to slow down the dripping speed of the lubricating liquid. Specifically, the lubricating liquid is poured into the lubrication tank 301. The lubricating liquid first wets the sponge rod 303, and the sponge rod 303 decelerates the lubricating liquid, so that the lubricating liquid component drips into the lubrication port 304 for lubricating the rotating needle 204, and tries to ensure the sensitivity of the rotating needle 204.

[0037] Working principle:

[0038] The anti-rollover device of this hovercraft is used to calibrate the anti-rollover structure 2 by adjusting the position of the contact switch 210. When the driver turns, the contact switch 210 tilts along with the hull 1, while the rotating needle 204 is perpendicular to the water surface due to its own weight. When the contact switch 210 touches the rotating needle 204, the air pump 212 on one side of the contact switch 210 is started, and it quickly injects air into the square tube 214 through the air outlet pipe 213 and finally sprays out quickly through the nozzle 215, so as to coordinate the hull 1 and try to avoid rollover.

[0039] For the anti-rollover device of this hovercraft, the lubricating liquid is poured into the lubrication tank 301. The lubricating liquid first wets the sponge rod 303, and the sponge rod 303 decelerates the lubricating liquid, so that the lubricating liquid component drips into the lubrication port 304 for lubricating the rotating needle 204, and tries to ensure the sensitivity of the rotating needle 204.
