Description

AIRPORT PRODUCT INJECTION EQUIPMENT AND CORRESPONDING DEVICE

Field of the invention

The present invention relates to equipment, intended to be carried by a drone, making it possible to inject a product, such as an insecticide product, inside a nest, such as an insect nest, located in height.

The invention also relates to a drone equipped with such injection equipment.

Some animals, such as hornets or processionary caterpillars, build nests that can house thousands of individuals. For some species, for example hornets and processionary caterpillars, these nests are usually built high up, for example in the branches of a tree.

Some of these animals are harmful and/or invasive animals whose population should be regulated. Thus, the presence of a hornet's nest near a dwelling or the passage of humans can represent a danger. In addition, hornets of species commonly called "Asian hornets", originating from Asia, have recently been introduced into Europe and North Africa, where they proliferate to the detriment of other insect species, such as bees whose they feed. It is usually recognized that this species of hornets is, in Europe and North Africa, a pest whose population should be regulated.

The processionary caterpillar is also an animal that has recently been introduced in certain regions. These caterpillars cause a lot of damage and their population must be regulated.

Prior art

To regulate the population of these animals, the most effective method is to destroy their nests. This destruction can however prove to be difficult, in particular for Asian hornets or processionary caterpillars. Indeed, these two species build their nests in trees, at heights that can be significant, of the order of a few tens of meters. Access to these nests is therefore often difficult.

To destroy these nests, it is known that an operator, wearing suitable protection, approaches them using a ladder or a basket and sprays the nest with a large quantity of insecticide product. This method is sometimes difficult to implement, when the nest is located at great heights or in an inaccessible place. It has thus been proposed, by certain operators, to carry out such spraying using a drone.

Moreover, such spraying leads to the dispersion on the nest and around the nest of a large quantity of a very powerful insecticide product, likely to disturb and pollute the environment. Thus, after its destruction by insecticides, the nest remains covered with an insecticide product likely to contaminate birds landing on the nest. Moreover, since this method mainly kills the insects when they leave the nest, many dead insects can be found around a nest. They can then be eaten by birds which then risk poisoning themselves with the insecticide product.

Another known method consists in injecting an insecticide product directly inside the nest, using a lance forming a pipe and held from the ground by an operator. This operator tries to pierce the nest with the end of the lance to inject the product directly into it. This method is often limited to nests located at relatively low heights, due to the difficulty of implementing a very long spear. Furthermore, it causes the bottom of the nest to be pierced in order to inject the product therein. The hole thus formed allows the product, after injection, to fall back out of the nest by gravity, which leads to environmental pollution.

Objectives of the invention

The present invention aims to overcome these drawbacks of the prior art.

In particular, the present invention aims to provide a solution for destroying insect nests that are not easily accessible, in particular located at a height, which makes it possible to avoid the dispersion in the environment of harmful products such as insecticides.

In particular, an object of the present invention is to provide such a means which allows the easy destruction of such nests located at very great height or in places that are not easily accessible.

Yet another object of the invention is to provide such a method which allows the destruction of such nests using a reduced quantity of products, such as insecticide products.

A particular objective of the invention is to provide equipment and a method allowing the destruction of such nests by confining the product used inside the destroyed nest, in order to limit its impact on the environment.

These objectives, as well as others that will appear more clearly later, are achieved using product injection equipment, suitable to be carried by a drone, comprising:

means of attachment to the drone,

a reservoir of product to be injected,

an injection tube,

a mechanism for delivering the product, connected to a first end of the injection tube, and capable of placing the injection tube and the reservoir in communication.
According to the invention, this equipment comprises a penetration head, assembled at a second end of the injection tube, the penetration head comprising drilling and/or cutting means making it capable of penetrating into a wall of a nest insects, and the penetration head having at least one injection hole, in communication with the injection tube and opening onto an external surface of the penetration head.

Thus, this equipment allows the injection of products, for example insecticide products, inside the insect nest itself, which allows a much more effective destruction of the latter and avoids the dissemination of insecticide product. The fact that the equipment is carried by a drone makes it possible to treat nests located at heights making it inaccessible by other means.

Advantageously, the penetration head is movable, relative to the means of attachment to the drone, between a first position and a second position in which it is more distant from the means of attachment to the drone than in the first position, and the equipment of injection comprises means for driving the penetration head from the first position to the second position.

The equipment for injecting products, according to the invention, thus performs a double action on the nest: a mechanical action pushing the penetration head forwards to ensure its good penetration into the nest and an action of injecting products. These two actions can be simultaneous or combined to ensure the most effective destruction of the nest.

Preferably, the penetration head is integral with the second end of the injection tube, and the injection tube is movable with the penetration head, relative to the means of attachment to the drone, between the first position and the second position .

According to an advantageous embodiment, the mechanism for delivering the product comprises a shuttle secured to the injection tube, and movable with the injection tube between the first position, in which the shuttle blocks the first end of the injection tube, and the second position, in which the shuttle places the injection tube in communication with the reservoir of product to be injected.

This shuttle makes it possible to simultaneously ensure the mechanical action and the product delivery action of the injection equipment.

Advantageously, the drive means of the penetration head comprise a trigger mechanism able to maintain the shuttle in the first position, and, in response to a command, to drive the shuttle into the second position.

Advantageously, the trigger mechanism comprises at least one spring capable of driving the shuttle from the first to the second position.

Advantageously, the trigger mechanism comprises at least one electromagnetic suction cup capable of holding in place a ferromagnetic plate linked to the shuttle, in the first position of the shuttle.

Such an electromagnetic lock allows effective maintenance of the shuttle in its first position, without energy consumption, and triggering requiring only very little energy.

Preferably, the means for piercing and/or cutting the penetration head comprise at least one tip.

This point allows the penetration head to easily penetrate the wall of the nest.

Advantageously, the means for drilling and/or cutting the penetration head comprise at least one metal blade.

The blade, or blades, advantageously make it possible to facilitate the introduction of the penetration head into the nest. They also make it possible to destroy the structure of the nest around the penetration head, in order to facilitate the diffusion into the nest of the product injected by this head.

Advantageously, the product injection equipment comprises a support surface placed close to the penetration head, able to limit the penetration of the penetration head into a wall of an insect nest.

By limiting the penetration of the penetration head into the nest, the support surface avoids any situation of the penetration head getting stuck in the nest, which could present a danger for the drone carrying the injection equipment of product.

Advantageously, the product injection equipment comprises at least one electric accumulator, the means of attachment to the drone being located between the battery and the penetration head.

This distribution of the battery and the penetration head allows a balancing of the masses around the center of gravity of the drone.

The invention also relates to a device for injecting product into an insect nest, comprising a drone equipped with equipment for injecting product as described above.

Detailed Description of Embodiments of the Invention
Structure of product injection equipment

FIG. 1 represents, in side view, a drone 1 carrying equipment for injecting product into a nest according to one embodiment of the invention. The drone 1 can be a drone of a known type, comprising a body 11 on which are mounted lifting propellers 12. Advantageously, the injection equipment according to the invention is mounted under the drone 1.

This injection equipment comprises a support board 2, extending substantially horizontally and connected to the drone 1 via support rods 13, which constitute means of attachment to the drone. This support board 2 carries the product delivery mechanism, comprising the connecting part 3, the reservoir 4 fixed to the connecting part 3 and the trigger mechanism 7. This product delivery mechanism makes it possible to send the product to inject into an injection tube 5 which ends in a penetration head 6.

In the rest of the description, it is considered that the horizontal plane is the plane passing through the propellers of the drone 1, and that the injection tube 5 materializes a horizontal axis 10 extending from the front to the rear of the equipment. injection, the front end of the injection equipment being constituted by the penetration head 6 and the rear end being constituted by the end of the support board 2 which is opposite to this point 6.
Delivery mechanism

A first end of the injection tube 5 is attached to the product delivery mechanism, visible in the sectional views of Figures 5 and 6. This product delivery mechanism comprises a connecting piece 3 shown in perspective in Figures 3 and 4. This connecting piece 3 comprises a cover portion 31, consisting of a plate having, on its underside, a first threaded cylindrical edge 311 allowing assembly by screwing of the reservoir 4. This underside of the cover portion 31 also has a second cylindrical edge 312, concentric with the first threaded cylindrical edge 311 and of slightly larger diameter.

A seal 313 is advantageously placed between the first cylindrical edge 311 and the second cylindrical edge 312 and can be crushed by the edge of the tank 4 when the latter is screwed onto the first threaded cylindrical edge 311 . Thus, the cover portion 31 of the connecting piece 3 closes the reservoir 4 in a sealed manner.

Outside the second cylindrical border 312, the cover portion 31 of the connecting piece 3 has holes 316 allowing it to be assembled to the board 2, via the support rods 13.

The cover portion 31 is pierced by a central hole 314, in which is placed a substantially vertical tube 315. This tube 315, or plunger, extends into the tank 4, almost to the bottom of this tank 4. At its upper end, this tube 315 opens, through the hole 314, inside a horizontal pipe 32 of the connecting piece 3, extending over the cover portion 31, along the axis 10.

Another hole, not visible in the figures, is pierced through the cover portion 31. This hole communicates the underside of the cover portion 31, and therefore the inside of the reservoir 4, with a valve 34 located on the upper face of the cover portion 31. This valve allows the introduction into the reservoir 4 of pressurized gas and prevents the exit of this gas.

A shuttle 33 is slidably mounted in the horizontal pipe 32 of the product delivery mechanism 3. This shuttle 33 has a generally cylindrical outer shape on which are placed three seals 331, 332, 333, held in peripheral grooves of the outer surface of shuttle 33. Between seals 331 and 332, shutter shuttle 33 has a perfectly cylindrical surface. When these seals 331 and 332 are located on either side of the hole 314, as shown in FIG. 5, the shuttle 33 therefore closes the end of this hole 314 facing the horizontal pipe 32. When the shuttle 33 is in such a position, called first position or closed position, it is considered that the product delivery mechanism is in a closed position.

On the other hand, between the seal 332 and the seal 333, the outer surface of the shuttle 33 has a peripheral groove 334, on which open openings 335 which put the peripheral groove 334 in communication with an internal chamber 336 of the shuttle 33.

When the seals 332 and 333 are placed on either side of the hole 314, as shown in FIG. 6, the hole 314 is placed in communication with the internal chamber 336 of the shuttle 33. This internal chamber 336 itself opens on the first end of the injection tube 5, which is assembled by screwing inside the internal chamber 336. When the shuttle 33 is in such a position, called second position or open position, which puts the inside of the reservoir 4 in communication with the injection tube 5, it is considered that the product delivery mechanism is in an open position.

In the embodiment shown, the injection tube 5 is integral with the shuttle 33, and the movement of the shuttle 33 between the first position and the second position therefore causes identical movements of the injection tube 5. It is however possible, in other embodiments, for the internal chamber 336 of the shuttle 33 to open onto the first end of the injection tube 5 without this injection tube 5 being integral with the shuttle 33. The shuttle 33 could then be movable between its first position and its second position without driving the injection tube 5.
Trigger mechanism

In the embodiment represented by the figures, the product delivery mechanism comprises a trigger mechanism 7, at the rear of the connecting piece 3, which makes it possible to maintain the shuttle 33 in its closed position and, in response to a command, to move it to its open position.

This trigger mechanism 7 comprises a rod 71 circulating in the horizontal pipe 32 and fixed, by its first end, to the rear of the shuttle 33 and, by its second end, to a ferromagnetic plate 75. Between these two ends, the rod 71 carries a collar 72. A spring 73 surrounds the rod 71, in the horizontal pipe 32, between the collar 72 and a plate 74 for closing the horizontal pipe 32. This plate 74 is pierced to allow the passage of the rod 71 , but blocks the spring 73.

The trigger mechanism 7 also comprises an electromagnetic suction cup 76 placed outside the horizontal pipe 32. In the closed position of the product delivery mechanism, represented by FIG. 5, the ferromagnetic plate 75 is pressed against the suction cup 76 and is magnetically retained by this electromagnetic suction cup 76. In this position, the spring 73 is compressed between the collar 72 and the plate 74.

Such an electromagnetic lock 76 comprises a permanent magnet capable of magnetically attracting and holding the ferromagnetic plate 75. This permanent magnet is surrounded by an electromagnetic coil capable, when it is electrically powered, of producing a magnetic field opposite to that of the permanent magnet, thus canceling the latter. Thus, the electromagnetic lock 76 exerts a magnetic attraction when it is not electrically powered and no longer exerts this attraction when it is electrically powered.

In the embodiment shown, it is possible to place the trigger mechanism 7 in its closed position by pushing the injection tube 5 backwards, compressing the spring 73, until the ferromagnetic plate 75 is in contact with the electromagnetic lock 76 and is retained by it. The trigger mechanism 7 and the product delivery mechanism 3 remain in this position until the electromagnetic suction cup 76 is electrically powered and releases the ferromagnetic plate 75.

As soon as the electromagnetic lock 76 is electrically powered, it releases the ferromagnetic plate 75. The spring 73 then deploys, pushing back the collar 72, until placing the product delivery mechanism in the open position shown in the figure 6.
Trigger control and power supply

The product delivery mechanism also comprises an electronic control card, not shown, capable of managing the electrical supply to the electromagnetic suction cup 76 and comprising a radio communication module enabling it to control the electrical supply of the electromagnetic suction cup 76 by response to a particular radio signal. This radio communication module preferably uses radio frequencies chosen so as not to interfere with the radio frequencies used to control the drone.

The injection equipment also comprises an electric accumulator 8, constituted for example by a battery, allowing the electric supply of the electronic control card and of the electromagnetic suction cup 76. Advantageously, this electric accumulator 8 is carried by the board of support 2, close to the rear end of this support board 2, opposite to the penetration head 6. This position of the electric accumulator 8 makes it possible to advantageously distribute the masses of the injection equipment, the mass of the injection tube 5 and the penetration head 6 placed at the front of the drone 1, being balanced by the mass of the electric accumulator 8 at the rear of the drone 1.
Tube

The injection tube 5, which is fixed by its first end to the product delivery mechanism 3 and at its second end to the penetration head 6, advantageously has a length of between 1 and 2 meters. This length allows the penetration head 6 to be located at a sufficient distance from the propellers 12 of the drone 1, so that the drone 1 can approach a nest and cause this penetration head 6 to penetrate into the nest without its propellers 12 are not likely to come into contact with the nest or with the branches of trees surrounding it.

The injection tube 5 is preferably made of metallic material such as titanium. It can advantageously be surrounded, over at least a part of its length, by a sheath 51 allowing it to improve its mechanical strength in bending. This sheath 51 can thus, advantageously, be constituted by a tube made of composite material having good resistance to bending, in which the injection tube 5 is inserted and secured.

In the embodiment shown, the injection tube 5 and the sheath 51, integral with this injection tube 5, are slidably mounted in a fixing lug 21 carried by the support board 2, at the front of this support board 2. The injection tube 5 can thus move, with the shuttle 33, between a first position and a second position. In other embodiments, it is also possible for this injection tube to be fixed with respect to the support board.
Penetration head

The penetration head 6 is shown in front view in FIG. 7 and in section, side view, in FIG. 8. This penetration head 6 has a conical tip 61, made of metallic material such as titanium, which extended by an injection portion 62 which, in the embodiment shown, is of generally frustoconical shape. this injection portion 62 could also, in other embodiments, have a different shape.

The injection portion 62 comprises an internal chamber 620, onto which the second end of the injection tube 5 opens. Injection holes 63 start from this internal chamber 620 and open onto the outer surface of the injection portion 62 .

The outer surface of the injection portion 62 has three triangular fins 641, 642, 643, each extending substantially in a plane passing through the axis 10. These fins 641, 642, 643 preferably belong to the same part as the injection portion 62, and are therefore also made of plastic material. Metal blades 651, 652, 653, mounted respectively by screwing on these fins 641, 642, 643, allow these fins 641, 642, and 643 to have a sharp edge.

A stop disc 66 is pressed against the base of the injection portion 62. Having a larger diameter than that of the base of the injection portion 62, it constitutes a bearing surface, placed close to the penetration head, which makes it possible to limit the penetration of the penetration head 6 into a nest, for example a hornet's nest. This limitation of the penetration makes it possible to prevent any jamming of the penetration head 6 inside a nest.

The penetration head 6 is intended to sink into the lateral flank of an insect nest, such as a hornet's or caterpillar's nest. The shape and hardness of the conical tip 61 allow it to easily penetrate such a nest. Furthermore, the metal blades 651, 652 and 653, carried by the fins 641, 642 and 643, can cut, during the penetration of the penetration head 6, the structure of these nests around the injection portion 62. This cutout facilitates the penetration of the penetration head 6.

In the embodiment shown, the penetration head 6 is assembled to the second end of the injection tube 5 via a connection sleeve 67, which is screwed inside the internal chamber 620 and has a collar 670 capable of holding the stop disc 66 against the base of the portion 62. The second end of the injection tube 5 can be inserted into a cylindrical opening passing through the connection sleeve 67 and be assembled there, so as to sealed, via a clamping ring 671 screwed onto the connection sleeve 67 and compressing an olive seal 672 against the injection tube 5 and the connection sleeve 67.

This assembly integral with the penetration head 6 on the injection tube 5 allows, in the embodiment shown, that the penetration head 6 can move, with the injection tube 5, between a first position and a second position, in which the penetration head 6 is farther from the drone than in the first position.

In other possible embodiments, the injection tube 5 can be fixed relative to the drone. The penetration head 6 can then, in an advantageous variant, be movable relative to the injection tube 5, for example in translation, between a first position and a second position, in which the penetration head 6 is farther from the drone than in the first position. The equipment then comprises drive means adapted to drive the penetration head from its first position to its second position.
Equipment operation

To implement the product injection equipment represented by the figures to destroy an insect nest at height, for example a hornet's nest or a caterpillar's nest, an operator assembles this injection equipment below the drone 1. He pours the desired dose of insecticide product into reservoir 4, then screws this reservoir 4 onto the cover portion 31 of the equipment. For example, for the destruction of an Asian hornet nest, it is possible to put in tank 4 a quantity of 120 milliliters of insecticide product.

Then, the operator pushes the injection tube 5 backwards, towards the connecting piece 3, by compressing the spring 73 until the ferromagnetic plate 75 is attracted and held by the electromagnetic suction cup 76. The mechanism delivery of the product is then in the closed position.

The operator then connects a gas compressor or a bottle of pressurized gas to the valve 34 in communication with the tank 4 and injects pressurized gas into this tank 4. By way of example, for the destruction of a nest of Asian hornets, it is possible to fill this tank 4 with gas under a pressure of 7 bars. The insecticide injection equipment is then ready for use.

The operator can then take off the drone 1 carrying the injection equipment and move it until the penetration head 6 comes into contact with a side wall of the nest to be destroyed.

To facilitate this movement, the drone 1 and the injection equipment can carry one or more cameras (not shown in the figures). By way of example, a first camera, focused on the penetration head 6, can be carried by the mounting lug 21 and a second camera can be carried by one of the support legs of the drone (not shown). These cameras are advantageously connected to a dedicated electronic card transmitting the data to the pilot of the drone, who can thus carry out precise piloting of the drone near the nest of insects to be treated.

By the action of the propellers 12 of the drone 1, the penetration head 6 can begin to pierce this side wall and penetrate into the nest to be destroyed. When this penetration is sufficient, the operator can send, via his radio control, the radio signal commanding the triggering of the injection.

Upon receipt of this radio signal, the electronic product injection equipment control board electrically supplies the electromagnetic lock 76, which then releases the ferromagnetic plate 75. The assembly formed by the rod 71, the shuttle 33 and the injection tube 5 then moves forward. This sudden displacement, by a distance of approximately 20 mm, has two effects. On the one hand, it suddenly pushes the penetration head 6 forwards, from its first position to its second position, which has the effect of completing the sinking of this penetration head 6 into the nest, until 'that the stop disc 66 is in contact with the wall of the nest. On the other hand, it causes the shuttle 33 to pass into its open position, which puts the injection tube 5 in communication with the reservoir 4.

The pressure of the gas contained in the reservoir 4 then pushes the insecticide product, which occupies the bottom of the reservoir 4, into the dip tube 315. This product then passes, through the shuttle 33, into the injection tube 5, which leads to the penetration head 6. Having arrived in the internal chamber 620 of the penetration head 6, it is ejected, still pushed by the pressurized gas, through the injection holes 63. The penetration head 6 being, at this time, embedded in the nest to be destroyed, the injection of the insecticide product takes place directly inside the nest.

If the gas pressure in reservoir 4, before injection, is 7 bars, this gas undergoes expansion during the ejection of the product. However, when the product is ejected through the injection holes 63, the pressure drop in the system is such that the injection pressure is around 5.5 bars.
Effect of injection in the nest

This pressurized injection of the product inside the nest itself makes it possible to effectively eliminate the insects contained in the nest and thus to destroy it. It should be noted that the mechanical action of piercing the nest and injecting under pressure also contributes to weakening the nest, which accelerates its destruction after the elimination of insects.
Since the insecticide product is inside the nest itself, and not on its surface, its impact on the environment is limited. The fact that the injection takes place through a side hole prevents this product from flowing out by gravity through the injection hole. The insecticide product, as well as the dead insects and the parts of the nest contaminated by this product, therefore remain largely inside the nest, after the injection, for a period generally greater than the time necessary for the insecticide product to is degraded naturally.
