Description

TECHNICAL FIELD The present invention relates to a takeoff and landing platform for unmanned aerial vehicles, and more particularly to a takeoff and landing platform for unmanned aerial vehicles capable of stabilizing the posture during takeoff and landing.

2. Description of the Related Art In recent years, unmanned flying objects that fly by remote control or automatic control have become popular, and cameras are mounted on these unmanned flying objects to take aerial photographs of locations that are difficult for humans to approach.

By the way, unmanned flying objects are often taken off and landed based on a certain base point, but the terrain at this base point is not necessarily flat, and due to this, the attitude of the unmanned flying object during takeoff and landing becomes unstable. It is assumed that it will be lost.

If such a problem occurs, for example, the unmanned flying object may rise obliquely at the start of flight, or when the unmanned flying object tilts when landing, the blades may contact the ground and be damaged. There is a demand for countermeasures.

For example, Patent Literature 1 proposes a conventional technique intended to meet such demands.

In this conventional technology, a rectangular platform is installed at the base point of the flight of the unmanned flying object to form a nearly flat takeoff and landing surface, and the unmanned flying object takes off and arrives on this takeoff and landing surface. It can be expected that the posture of the body at the time of departure and arrival is stabilized as much as possible.

By the way, the above-mentioned platform requires a certain amount of weight in order to withstand inadvertent movements caused by impacts when the unmanned aerial vehicle lands.

If the weight of the platform is ensured in this way, it is assumed that the work for transporting and installing this platform to the base point will be affected, and the installation work will be complicated.

The present invention was made to solve the above-mentioned problems in the prior art, and while stabilizing the attitude of the unmanned air vehicle when taking off and landing, the weight is reduced when it is not in use or when it is transported, so that it is easy to operate. The problem to be solved is to provide a platform for take-off and take-off of an unmanned aerial vehicle that can be installed.

A take-off platform for an unmanned aerial vehicle according to the present invention comprises a base plate and an upper plate provided above the base plate while forming a space between the base plates for taking off and landing of the unmanned aerial vehicle, the base plate comprising: A lift bar for lifting the side of the base plate is provided on the side of the base plate, and the side of the base plate opposite to the side on which the lift bar is provided is grounded when the side of the base plate is lifted. A rolling element is provided, and a weight for restraining unnecessary movement of the base plate is detachably accommodated in the space.

In the take-off platform for the unmanned aerial vehicle constructed in this manner, the lift bar is gripped and lifted to ground the rolling element, thereby rotating the base plate around the rolling element and moving the base plate from the installation surface. float.

As a result, the main constituent members of the landing platform, excluding the rolling elements, are kept floating above the installation surface.

In this state, by pushing the launch platform, the launch platform is moved to the installation position.

Here, since most of the weight of the take-off platform is supported by the rolling bodies, the above-described movement of the take-off platform can be easily performed.

After moving the take-off platform to the installation position, the take-off platform can be installed by lowering the lift bar and bringing the base plate into contact with the installation surface.

When the takeoff platform is installed, its upper plate forms a flat takeoff and landing surface, and the unmanned air vehicle can take off and land on this flat upper plate.

Therefore, the unmanned flying object can be maintained in a substantially horizontal posture when it is lowered onto the upper plate, and can be floated substantially vertically when starting, thereby maintaining a stable take-off/arrival posture.

On the other hand, since the weight is detachably mounted in the space formed between the base plate and the upper plate, by replacing the weight, the weight can be removed from the installation location of the landing platform. It can be increased or decreased according to the condition of the surface.

For example, if the installation surface is made of concrete, asphalt, or the like and is relatively stable, the base plate is stably supported, so the force that presses the base plate against the installation surface can be reduced.

Further, when the installation surface is formed of gravel, soil, or the like and has unevenness on the surface, it is necessary to press the installation surface with a large force in order to smooth the unevenness.

By adjusting the weight of the weight according to the situation of the installation surface, it is possible to adjust and stabilize the attitude of the landing/departure platform.

When the take-off platform is to be withdrawn, the work described above can be reversed.

Also, a large number of struts are erected on the base plate, an upper plate is attached to these struts, and a space for storing weights is formed between the base plate, the plurality of struts, and the upper plate. can be configured as

With such a configuration, the structural members forming the space can be made up of a large number of struts, so that the weight of the structural members forming the space and, in turn, the take-off and landing platform can be reduced.

In addition, the upper plate is divided into a plurality of parts, and a connector is provided between at least one of the divided upper plates and the remaining upper plate to connect these parts in a rotatable or contactable and detachable manner. can do.

With such a configuration, by rotating one of the divided upper plates, the upper space formed below it can be opened.

By opening the upper part of the space in this way, the weight stored in the space can be exposed, and the work of storing or exchanging the weight can be facilitated.

Also, the base plate, the upper plate, and the plurality of struts may be detachably connected.

With such a configuration, when not in use, they can be disassembled and stored, so that the storage space can be kept small.

It is also possible to provide a shock absorbing material on the surface of the upper plate on which the unmanned flying object takes off and arrives.

By adopting such a configuration, it is possible to reduce the impact applied to the unmanned flying object when the unmanned flying object takes off and arrives.

Then, the impact absorbing material can be formed in a sheet shape and detachably attached to the upper plate via the fastening member.

With such a configuration, the impact absorbing member can be removed and stored when not in use, thereby preventing deterioration thereof and facilitating replacement work in maintenance and the like.

Additionally, the weight can be constituted by a water can.
With such a configuration, the weight can be adjusted by adjusting the amount of water filled in the weight, and when the weight is removed, the weight can be minimized by discarding the water in the weight. can be moved more easily.

According to the present invention, there is provided a platform for taking off and landing an unmanned aerial vehicle that can be installed with simple work while stabilizing the attitude of the unmanned aerial vehicle when taking off and landing, while reducing the weight of the unmanned aerial vehicle when not in use or during transportation. can provide.
