Detailed Description
Referring to fig. 1 to 4, in an embodiment of the present invention, an electric power engineering emergency vehicle is provided, including:
The vehicle body 1 is provided with a parking platform 11 fixed on the top, wherein the parking platform 11 is of a groove-shaped structure; and an emergency platform assembly 2 which is parked on the parking platform 11;
Wherein, the emergency platform assembly 2 comprises:
A body 21;
Four foldable arms 24, wherein the foldable arms 24 are fixed on the machine body 21, and power pulp 25 is further arranged on the foldable arms 24;
a first insulation stage 22, the first insulation stage 22 being fixed to the body 21; the at least two telescopic rods 26 are arranged on the first insulating platform 22, the telescopic ends of the telescopic rods 26 are connected with rope bodies 27, and the other ends of the rope bodies 27 are connected with safety hooks 28;

In this embodiment, the vehicle body 1 is used as the basis of the whole rescue vehicle, provides stable supporting and transporting capabilities, and the parking platform 11 is designed into a groove-shaped structure, so that the rescue platform assembly 2 is convenient to park and take off, and the rescue platform assembly 2 can be fixed on the parking platform 11 through parts such as external ropes in the process of transporting the rescue platform assembly 2 by using the vehicle body 1, so that the stability of the rescue platform assembly 2 in the moving process is ensured.
In this embodiment, the four foldable arms 24 make the rescue platform assembly 2 more compact for easy transportation and storage. At the same time, after being unfolded, the stable flying capability can be provided, and referring to fig. 1 or 2, the top of the main body 21 can be configured to be as flat as possible so as to install the first insulation platform 22, and the design of the first insulation platform 22 is very important, as it can ensure the personal safety of maintenance personnel working near the high-voltage cable. The first insulating platform 22 is often formed of an insulating material that prevents electrical current from passing through the platform to cause injury to maintenance personnel.
In this embodiment, the combination of the telescopic rod 26, the rope 27 and the safety hook 28 has a certain flexibility, so that the rescue platform assembly 2 can be easily mounted on a cable, and a stable working platform is provided for maintenance personnel, and in a preferred embodiment, the telescopic rod 26 is configured to be four.
The operation flow is as follows:
During rescue, the rescue platform assembly 2 takes off from the parking platform 11 and flies below the cable.
The operator uses the safety hook 28 to firmly mount the rescue platform assembly 2 on the cable, thereby providing a safe working environment for maintenance personnel.
The maintenance personnel perform the necessary maintenance work on the first insulating platform 22.
The design not only solves the accessibility problem of maintenance of the high-voltage cable in the remote area, but also greatly improves the maintenance efficiency and safety. Through the introduction of unmanned aerial vehicle technique, the electric power engineering rescue vehicle can respond fast under complicated topography and adverse circumstances, provides powerful guarantee for electric power system's steady operation.
It should be noted that, in this embodiment, by detecting the wind speed, the rescue platform assembly may determine whether the current flight environment is suitable for rescue operation, or formulate a rescue strategy according to the wind speed, and of course, the wind speed data may also help the control system of the rescue platform assembly 2 to more accurately adjust the flight attitude and the power output, so as to ensure that the unmanned aerial vehicle remains stable in the flight process.
Specifically, if the current wind speed data is between the first wind speed threshold value and the second wind speed threshold value, the telescopic rod 26 is contracted to make the rope 27 in a straightened state, and the emergency platform assembly can be better fixed on the cable by means of the arrangement, so that shaking caused by wind speed is reduced, and operation stability is improved.
If the current wind speed data is between the second wind speed threshold value and the third wind speed threshold value, the power slurry 25 is in a working state, so that the emergency platform assembly 2 is kept in a stable state, and the unmanned aerial vehicle can still safely and stably operate under the medium wind speed condition.
The vehicle body 1 is also provided with a bin body 12, the bin body 12 is internally provided with a wind prevention assembly 3, and if the current wind speed data is larger than a third wind speed threshold value, the wind prevention assembly 3 leaves the vehicle body 1 and forms a static space, and the static space is used for accommodating the emergency platform assembly 2. This static space can provide a relatively stable environment for the unmanned aerial vehicle, avoiding its direct influence by extreme wind speeds.
Obviously, the third wind speed threshold is greater than the second wind speed threshold, and the second wind speed threshold is greater than the first wind speed threshold, which will not be described in detail herein.

The wind-proof ring 32 is carried by the unmanned aerial vehicle 31, and the shape thereof can be adjusted according to the need to adapt to different environments and use requirements, and the wind-proof ring 32 is made of flexible materials, so that the wind-proof ring can be moderately deformed along with the change of wind force, and meanwhile, the overall stability is maintained. The surface of the windbreak ring 32 has micro holes which allow a small amount of air to circulate, reducing windage.
In addition, a weight increasing ring 33 is fixed below the wind-proof ring 32, and the main function of the weight increasing ring is to increase the overall weight of the wind-proof assembly 3 and improve the stability of the wind-proof assembly under the action of wind force.
The weight ring 33 is designed to ensure stability of the wind-proof assembly 3 in strong winds and to avoid excessive load on the flight capacity of the unmanned aerial vehicle 31 due to the weight ring 33.
In this embodiment, the first insulating platform 22 is slidably connected to the second insulating platform 23 horizontally, which allows the second insulating platform 23 to move horizontally on the first insulating platform 22.
The sliding connection design can be flexibly adjusted according to actual needs, for example, in emergency operation, the position of the second insulation platform 23 can be adjusted according to the size and the position of the operation area, so that the second insulation platform is closer to an operation point, and the operation efficiency is improved.

It should be explained that the wind speed detection model is a relatively simplified model, but it can be realized to a certain extent that the wind speed can be measured and calculated only by using the GPS of the rescue platform assembly 2 itself, wherein when the rescue platform assembly 2 spirals for one turn, the rescue platform assembly 2 does not generate a net displacement in the horizontal direction relative to the surrounding air, i.e. the sum of the horizontal airspeed vectors thereof is zero. But due to the wind speed the horizontal speed (ground speed) of the rescue platform assembly 2 with respect to the ground is equal to the wind speed. Thus, at the end of hover, the average horizontal ground speed of the rescue platform assembly 2 is equal to the average horizontal wind speed.
