[0002] The occurrence of forest fires often results from the intertwining of various natural and human factors. Among natural factors, lightning strikes on trees, extremely dry and flammable ground vegetation caused by drought, and volcanic eruptions can all become the sources of forest fires. Especially under long-term dry and high-temperature weather conditions, combustible substances in the forest are extremely easy to be ignited and spread rapidly. Human factors are more complex and diverse, including but not limited to incomplete extinguishing of campfires during outdoor camping, accidentally igniting surrounding vegetation when burning garbage or crop straws, improper disposal of cigarette butts after smoking, and intentional arson. The significance of forest fire prevention and extinguishing is significant and far-reaching. The hoisting equipment for mobile water tanks for fire extinguishing is a commonly used equipment in forest fire fighting and emergency rescue scenarios, and can complete the hoisting and transportation tasks of large water tanks.

[0003] However, in the scenario of forest fire prevention and extinguishing, the personnel allocation is often limited, and the traditional hoisting method requires the cooperation of more personnel. Generally, one end of the hoisting rope is suspended on a helicopter, and the other end needs to be manually tightened by ground personnel on the lifting lug of the mobile water tank, which greatly increases the labor cost. Moreover, once it is not tightened, mistakes may occur during the hoisting operation, all of which may lead to serious accidents and the safety is not high.

[0004] Therefore, aiming at the problem that the above-mentioned traditional hoisting method for mobile water tanks highly relies on the assistance of ground personnel and is prone to leaving potential safety hazards due to improper operation coordination, a hoisting mechanism for a mobile water tank for fire extinguishing and its usage method can be designed.

The positioning component 13 can be quickly deployed and retracted, and the hook 1603 can be driven to rotate through the set suspension component 16, which is convenient for hooking the lifting lug of the mobile water tank correspondingly.

[0033] Please refer to Figures 3-5, in this embodiment, the winding assembly 6 further includes a first driving motor 601. The first driving motor 601 is installed inside the main body 1 of the mobile water tank hoisting mechanism. The right end of the first driving motor 601 is connected to a first output shaft 602.

The connecting seats 12 are rotatably connected to the lifting arms 14. The setting of the four lifting arms 14 improves the stability and safety of hoisting.

[0034] Please refer to Figures 5-6, in this embodiment, the positioning component 13 further includes an electric telescopic rod 1301. The lower end of the connecting disk 904 is provided with the electric telescopic rod 1301. The lower end of the electric telescopic rod 1301 is fixed with a special-shaped block 1302. The lower end of the special-shaped block 1302 is fixed with a rotating shaft 1303. The surface of the rotating shaft 1303 is connected with a connecting rod 1304. The connecting rod 1304 is rotatably connected with the rotating shaft 1303. There are four connecting rods 1304. By extending or contracting the electric telescopic rod 1301, the connecting rod 1304 is driven to rotate, so as to drive the four lifting arms 14 to adjust the angles simultaneously. The surface of the lifting arm 14 is fixed with a connecting piece 1305. The connecting piece 1305 is of a U-shaped structure. The connecting piece 1305 is rotatably connected with the connecting rod 1304. By the rotation of the connecting rod 1304, the lifting arm 14 can be flexibly unfolded and contracted, so as to facilitate the user to store or use. The suspension component 16 further includes a third driving motor 1601. The lower end of the mounting plate 15 is provided with the third driving motor 1601. The front end of the third driving motor 1601 is connected with a third output shaft 1602. The surface of the third output shaft 1602 is fixed with a hook 1603.

The protective sleeve 1604 is made of rubber. By the arrangement of the protective sleeve 1604, the hook 1603 is protected from damage, and the service life of the lifting mechanism is prolonged.

[0035] The using method of the mobile water tank lifting mechanism for fire extinguishing is as follows:

[0036] The first step is to turn on the camera 11 to observe the position of the hook 1603 in real time;

[0037] The second step is to unfold the four lifting arms 14 through the positioning component 13;

[0038] The third step is to lengthen the lifting rope 7 through the winding component 6 until the hook 1603 is close to the mobile water tank;

[0039] The fourth step is to adjust the angle of the lifting arm 14 through the rotating component 9 to ensure that the hook 1603 is close to the lifting lug of the mobile water tank;

[0040] The fifth step is to rotate the hook 1603 through the suspension component 16 so as to correspondingly hook the lifting lug of the mobile water tank.

[0041] When working, first install the hoisting mechanism mounting frame 3 on the helicopter. The helicopter can move the hoisting mechanism to the position to be hoisted. Then, observe the display screen 4 and monitor the hoisting state in real time through the camera 11. Next, contract the electric telescopic rod 1301, and at the same time, the two ends of the connecting rod 1304 rotate on the rotating shaft 1303 and the connecting piece 1305, so as to push the hoisting arm 14 to rotate on the angle adjustment connecting seat 12, and then the four hoisting arms 14 can be unfolded simultaneously. Then, start the first driving motor 601. The first output shaft 602 rotates in the sleeve 603, so that the rope winding frame 604 rotates. At the same time, cooperate with the auxiliary roller 606 to rotate on the fixed rod 605, so that the hoisting rope 7 is steadily lengthened until the hook 1603 approaches the mobile water tank. Secondly, start the second driving motor 902. The second output shaft 903 drives the connecting disk 904 to rotate until the hook 1603 under the hoisting arm 14 approaches the lifting lug of the water tank. Then, start the third driving motor 1601 to drive the hook 1603 on the third output shaft 1602 to rotate and penetrate into the lifting lug of the mobile water tank, so as to hook the lifting lug of the mobile water tank. Finally, wind up the hoisting rope 7 for subsequent hoisting operations.

[0042] Through the above steps, the automatic winding and unwinding of the hoisting rope is realized by the winding component. The angle of the hoisting arm can be adjusted correspondingly according to the position of the mobile water tank through the rotating component and the positioning component. The hook can also be driven to rotate by the hanging component, which is convenient for hooking the lifting lug of the mobile water tank correspondingly, so as to solve the problem that the traditional hoisting method of the mobile water tank for fire extinguishing highly depends on the assistance of ground personnel and is prone to leaving potential safety hazards due to improper operation cooperation.

[0043] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
