Description

The present invention relates to a launch / wear platform on which an unmanned aircraft takes off and landing, and in particular relates to a launch / wear platform for an unmanned aircraft that can stabilize the attitude at the time of departure and arrival.

In recent years, unmanned air vehicles that fly by remote control or automatic control have become widespread, and cameras are mounted on these unmanned air vehicles to take aerial photographs of places that are difficult for humans to approach.

By the way, an unmanned aircraft is often landed and departed based on a certain base point, but the terrain at this base point is not always flat, and as a result, the attitude of the unmanned air vehicle at the time of departure and arrival becomes unstable. It is expected that it will end up.

If such a problem occurs, for example, a phenomenon in which the unmanned aircraft ascends diagonally at the start of flight or a phenomenon in which the unmanned aircraft tilts at the time of landing and its blades or the like come into contact with the ground or the like and are damaged may occur. There is a demand for countermeasures.

Then, a conventional technique for responding to such a request is proposed, for example, in Patent Document 1.

In this conventional technology, a rectangular platform is installed at the base point of the flight of an unmanned aircraft to form an almost flat landing surface, and the unmanned aircraft is landed on this landing surface. It can be expected to stabilize the posture of the body when it arrives and departs as much as possible.

By the way, the above-mentioned platform needs a certain amount of weight in order to withstand inadvertent movement caused by an impact at the time of landing of an unmanned aircraft.

If the weight of the platform is secured in this way, it is expected that the work when the platform is transported to the base point and installed will be affected, and the installation work will be complicated.

The present invention has been made to solve the above-mentioned problems in the prior art, and it is a simple operation to reduce the weight at the time of non-use or transportation while stabilizing the attitude at the time of departure and arrival of the unmanned aircraft. The challenge to be solved is to provide a platform for launching and wearing unmanned aircraft that can be installed.

The launch / attach platform of the unmanned aircraft of the present invention includes a base plate and an upper plate provided above the base plate while forming a space between the base plates and where the unmanned aircraft can land and depart. A lift bar for lifting the side portion of the base plate is provided on the side portion of the base plate, and the side portion of the base plate opposite to the side portion on which the lift bar is provided is grounded when the side portion of the base plate is lifted. A rolling element is provided, and a weight for restraining unnecessary movement of the base plate is detachably stored in the space.

In the platform for launching and wearing an unmanned aircraft configured in this way, by grasping and lifting the lift bar and grounding the rolling element, the base plate is rotated around the rolling element, and the base plate is mounted from the installation surface. Float.

This keeps the main components of the launch / wear platform, excluding the rolling elements, floating from the installation surface.

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

Here, since most of the weight of the launch / wear platform is supported by the rolling elements, the above-mentioned movement of the launch / wear platform can be easily performed.

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

Once the landing platform is installed, its upper plate forms a flat landing surface on which the unmanned aircraft can land and land.

Therefore, the unmanned aircraft can be maintained in a substantially horizontal attitude when descending on the upper plate, and can be levitated almost vertically at the time of starting, and can maintain a stable attitude of departure and arrival.

On the other hand, since the weight is detachably attached to the space formed between the base plate and the upper plate, by exchanging this weight, the weight can be installed at the installation location of the attachment / detachment platform. It can be increased or decreased depending on the situation of the surface.

For example, when the installation surface is formed of concrete, asphalt, or the like and is relatively stable, the base plate is stably supported, so that the force for pressing the base plate against the installation surface is small.

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

The weight of the weight can be adjusted according to the condition of the installation surface to adjust the attitude of the departure / arrival platform and stabilize it.

Then, when the platform is withdrawn, it can be performed by reversing the above-mentioned work.

Further, a large number of columns are erected on the base plate, and an upper plate is attached to these columns to form a space for storing weights between the base plate, the plurality of columns, and the upper plate. Can be configured as follows.

With such a configuration, the constituent members forming the space portion can be made into a large number of columns, so that the weight of the constituent members forming the space portion and, by extension, the departure / arrival platform can be reduced.

Further, the upper plate is divided into a plurality of parts, and a connecting tool is provided between at least one of the divided upper plates and the remaining upper plate to connect them so as to be rotatable or connectable. can do.

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

By opening the upper part of the space portion in this way, the weight stored in the space portion can be exposed, and the storage work, the replacement work, and the like of the weight can be facilitated.

Further, the base plate, the upper plate, and a plurality of columns can be detachably connected to each other.

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

It is also possible to provide a shock absorber on the surface of the upper plate on which the unmanned air vehicle is landed.

With such a configuration, it is possible to mitigate the impact applied to the unmanned aircraft when the unmanned aircraft arrives and departs.

Then, the shock absorbing material can be formed into a sheet shape and can be 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 to prevent its deterioration, and the replacement work can be facilitated in maintenance and the like.

Further, the weight can be composed of a water can.
With such a configuration, the amount of water filled in the weight is adjusted to adjust the weight, and at the time of removal, the water in the weight is discarded to minimize the weight of the departure / arrival platform. Can be made easier to move.

According to the present invention, there is an unmanned aircraft launch / wear platform that can be installed with simple work by reducing the weight during non-use or transportation while stabilizing the attitude of the unmanned aircraft when it arrives and departs. Can be provided.

The platform 1 of the present embodiment includes a base plate 2 and an upper plate 3 which is provided above the base plate 2 while forming a space S between the base plates 2 and where an unmanned aircraft F described later can be landed and departed. When a lift bar 4 for lifting the side portion of the base plate is provided on the side portion of the base plate 2, and the side portion of the base plate 2 is lifted on the side portion opposite to the side portion on which the lift bar 4 of the base plate 2 is provided. A rolling element 5 that is grounded to the ground is provided, and a weight W that restrains unnecessary movement of the base plate 2 is detachably stored in the space portion S.

As shown in FIGS. 1 and 2, a large number of columns 6 are erected on the base plate 2, and an upper plate 3 is attached to these columns 6, and the base plate 2 and the plurality of columns 6 are attached. A space portion S in which the weight W is housed is formed between the upper plate 3 and the upper plate 3.

A plurality of support members 7 having a rectangular cross section are attached to the upper end of each of the columns 6, and these support members 7 are installed so as to be parallel to each other at intervals in the front-rear direction of the platform 1. The upper plate 3 is fixed on the support member 7 of the above by a fixing means such as a screw.

In the present embodiment, the base plate 2, the upper plate 3, and a plurality of columns 6 are detachably connected to each other.

Further, as shown in FIGS. 2 and 3, the upper plate 3 is divided into a plurality of parts (divided into two in the present embodiment), and between at least one of the divided upper plates 3 and the remaining upper plate 3. Is provided with a connecting tool 8 made of a hinge that rotatably connects them.

As a result, one upper plate 3 can be rotated upward with the remaining upper plate 3 as a support, and the upward rotation causes the space portion S as shown in FIGS. 6 and 7. It is designed to open the upper part of.
By opening the upper part of the space portion S in this way, the weight W stored in the space portion S can be easily taken in and out.

A sheet-shaped shock absorbing material 9 is mounted on the surface of the upper plate 3 on which the unmanned flying object F is landed and landed over almost the entire surface.

As shown in FIGS. 1 and 5, the shock absorbing material 9 has a stopper 10 that penetrates the shock absorbing material 9 and the upper plate 3 at the upper limit and is locked to the shock absorbing material 9. , One end is fixed to the lower end of the stopper 10 and is routed so as to surround the lower part of the support member 7, and the other end of the locking string 11 is attached to the lower surface of the upper plate 3 and is detachably fastened. It is fixed by the fastening means R including the hook 12 to be formed.

Further, in the present embodiment, the weight W is composed of a water can.

After moving the platform 1 to the installation position, the platform 1 can be installed as shown in FIG. 1 by lowering the lift bar 4 and bringing the base plate 2 into contact with the installation surface.

When the platform 1 is installed, the impact absorbing material 9 and the upper plate 3 form a flat landing surface, and the unmanned aircraft F can land and land on the flat upper plate 3.

Therefore, the unmanned flying object F can be held in a substantially horizontal posture while descending on the upper plate 3, and can be floated substantially vertically at the time of starting, and can maintain a stable departure / arrival posture.

On the other hand, since the weight W is detachably attached to the space portion S formed between the base plate 2 and the upper plate 3, the weight W is adjusted by exchanging the weight W to adjust the weight of the platform 1. The force that presses against the installation surface can be adjusted to an appropriate value.

As a result, even if the installation surface is formed of gravel or soil and the surface is uneven, the unevenness can be eliminated by the force of pressing the platform 1 against the installation surface.
As a result, the platform 1 can be maintained in a stable attitude, and the arrival and departure of the unmanned aircraft F can be stabilized.

Further, when the installation surface is formed of concrete, asphalt, or the like and is relatively stable, the force for pressing the base plate 2 against the installation surface is small because the base plate 2 is stably supported. Can be adjusted to

Then, when the platform 1 is withdrawn, the work can be performed in the reverse of the above-mentioned work, but the weight of the platform 1 can be reduced by discarding and withdrawing the water of the weight W as necessary. , The above-mentioned withdrawal work can be made easier.

As described above, in the present embodiment, the installation work and the withdrawal work of the platform 1 can be simplified.

Further, by using a large number of columns 6 as the main constituent members forming the space portion S, it is possible to reduce the weight of the constituent members forming the space portion S, and thus the platform 1.

Then, as shown in FIG. 6, one of the upper plates 3 is rotated to open the upper part of the space portion S formed below the upper plate 3 to expose the weight W stored in the space portion S. As shown in FIG. 7, the weight W can be easily stored and replaced.

By detachably connecting the support column 6 to the base plate 2 and the upper plate 3, the storage space can be kept small by disassembling and storing them when not in use.

On the other hand, the unmanned vehicle F is lowered onto the upper plate 3 (shock absorber 9) of the installed platform 1 as shown by an arrow in FIG. 8, and is levitated as shown by an arrow in FIG.

Here, since the platform 1 is held in a stable attitude as described above, the unmanned aircraft F can be made to arrive and depart in a stable state.

In the present embodiment, the impact applied to the unmanned flying object F when the unmanned flying object F arrives and departs can be absorbed or mitigated by the impact absorbing material 9.
This makes it possible to prevent damage to the unmanned flying object F.

Further, when not in use, as shown in FIG. 5, by removing and storing the impact absorbing material 9, its deterioration can be prevented, and the replacement work can be made smooth in maintenance and the like. can.
