- the deployment of the marine exploration device can be provided by an engine M if the device is made for large boats, so for a much heavier device.
- the device is a lateral exploration kit.
- the deployment takes place on the sides of the live works of a boat.
- Said kit intended to be fixed on a boat, comprises a support T, deployment means C, H for positioning the support T in a predetermined position under the water Ci, and fastening means for maintaining the support
- the support T may be, for example, a flexible sheet sufficiently wide to accommodate an elongate occupant, for example a trampoline, a net or a technical fabric, the support T optionally comprising also one or more stiffening slats.
- the device is attached laterally to the boat, which may be a monohull boat (FIGS. 6, 7, 8) or to a watercraft (FIGS. unilateral ( Figure 6) or bilateral ( Figure 7, 8, 9). It allows a user to lie on the support T to observe the seabed.
- boat which may be a monohull boat (FIGS. 6, 7, 8) or to a watercraft (FIGS. unilateral ( Figure 6) or bilateral ( Figure 7, 8, 9). It allows a user to lie on the support T to observe the seabed.
- the deployment means C, H advantageously comprises two rigid structures, for example metal structures, C side faces of the boat and a guide system H. On each side face, there is a metal structure positioned towards the front of the boat. boat, and a metal structure positioned towards the rear of the boat.
- Each metal structure C comprises for example four sections such that, when the boat is on the water, a first section is parallel to the surface of the boat and by which the metal structure is fixed to said boat, a second section is perpendicular to the third section and of a length adapted so that the lower end is partially immersed, a third section is parallel to the surface of the water and immersed and a fourth section is parallel to the second section and at least partially immersed .
- the first section of the metal structure is for example connected to the guide system H of the deployment means C, H, said guide system H being attached to one boat.
- the structure C is for example foldable on itself. Once the exploration is complete, it can be folded and rotated along the boat so as not to hinder the rapid movement of the boat.
- the second section, perpendicular to the third section, and the third section, parallel to the surface of the water and immersed, of the structure C fold over each other along an axis perpendicular to the surface of the water, on the lateral face of the boat, so as to form a folded structure.
- the folded structure can then pivot at the level of the guide system at the level of the boat, and move from a vertical position to a horizontal position parallel to the surface of the boat and along the gunwale, so as not to hinder the rapid movement of the boat.
- the said metal structures C constitute a frame on which the support T is fixed.
- the structures C can be made of aluminum or stainless steel.
- the support T is where the user lies.
- Two elongated floats f are fixed on each side of the support T. They allow to maintain the user on the support in order to avoid a lateral displacement thereof and they ensure the system a better stability.
- Fixing the metal structure C to the boat can be achieved in several ways.
- the structure C can be maintained by a sleeve fixed to the freeboard of the boat.
- the structure C may have a perpendicular extension which penetrates the freeboard of the boat. In this case, nuts and a pin can be used for its attachment for example.
- the structure C can be fixed by a bearing H, bridges or ligatures ( Figures 6, 7, 8).
- Two front and rear bearings H can be permanently placed on the boat.
- the H bearing or the trigger guard is attached to an arciform pad. This pad is placed directly on the pneumatic coil of the boat ( Figure 9).
- the support is maintained in the position determined under water by the fixing means bl, b2, Y, b, which may for example be similar to those of the previous variant.
- the front and rear C structures are attached to the boat also by bits b to allow greater stability of the kit.
- the ends b can be attached to tabs t. In this way said frame thus ensures the maintenance of the support T in the determined position under the water Ci.
- the first deployment means C, H makes it possible to move the support T between a position outside the water C2 and the position determined under the water Ci, the fixing means b1, b2, Y, b, allowing the support T to be held in the position in the water Ci.
- the device attaches to two inflatable floats ( Figure 10).
- Figure 10 The machine thus formed is ultra-light, mountable and removable quickly. If necessary, it is collapsible. It can very easily be transported in a car when disassembled.
- the boat has two floats f2 which inflate for example through a manual or electric air pump.
- the floats may be composites or rotomoulded.
- Said device comprises two structures C: a front structure F and a rear structure Co, said front and rear structures being sufficiently rigid to maintain a constant gap between said two floats of said boat.
- Said structures C comprise hemlets at their ends, said hems being adapted so that said floats can be slid therein. The hems rub sufficiently on the floats in use to ensure stability of the floats. Other means of fixing the hems on the floats can also be added in order to guarantee this stability.
- the support T where the user is lying down also includes hemming on each side, said hems being adapted so that said floats can be slid therein.
- Both front and rear C structures are made of composites or aluminum.
- the structure Co is rigid enough to support the engine. It is also the container where the batteries of the electric motor are located. It should be noted that the structure Co is elevated relative to the support T, which allows a user to pass his fins between the structure Co and the support T ( Figure 10).
- the front structure C comprises a submerged central portion.
- a remote control system can be implemented to allow driving in the extended position and all the previous variants of these control modes can be used for this variant and the following.
- the underwater exploration device fixed on a boat is a so-called "beluga” craft which is a fast surface exploration craft, instantly convertible into exploration gear of the immediate underwater space.
- the device comprises a n-boat attached to a boat.
- the pivoting pod N constitutes the support T of said device.
- the axis H is a support and rotation axis transfixing the rear part of the nacelle N.
- the nacelle N pivots about this axis H. This pivoting movement makes it possible to move from the high position of the nacelle PH (FIG. 12). at the low position of the nacelle PB ( Figure 11).
- the front part of the n-boat is immersed, enough to put the user in the underwater exploration position, equipped simply with a mask and a snorkel.
- the user is for example lying on the n-pod.
- the user has access visually and directly to everything the underwater space in front and under it.
- the high position PH of the n-boat the user is for example in a sitting position on the seat S of the n-boat, and the movement of the machine may be faster to go to the site of exploration.
- the low position PB thus corresponds to the position determined under the water Ci and the high position PH therefore corresponds to the determined position out of the water C 2 .
- the remote controls can be provided by push-pull system for steering as well as for engaging the gears and accelerator.
- the controls are the same regardless of the navigation phase, for the user out of the water or in the surface water, with mask and snorkel. This gives a total functionality of the machine, which allows the user to move quickly out of the water, to go underwater observation instantly, by lowering the front part of the n-pod.
- N may for example be provided with a handlebar D.
- the handlebars allow the user to hold, for example as to activate the controls and maintain the direction.
- the seat S of the n-boat and the handlebar D are for example immersed.
- the vehicle is propelled either by an outboard motor M propulsive explosion, or by an electric motor.
- the boat on which the device is fixed comprises hulls K, the hulls K having internal flanks and external flanks.
- the nacelle N is for example fixed between the hulls K of the boat and thus pivots on its rear axle, its front part immersing itself.
- the structure of the nacelle N is for example in contact with the inner flanks of the hulls K.
- the boat comprises for example two hulls K and the nacelle N is fixed between these two shells K.
- the n-boat N fixed between the two hulls K is always in contact with the water whether it is in the high position PH or low PB.
- it forms with the set of two lateral K hulls a monohull hull in gull wing.
- the time to go down and up the device is reduced by shortening the distance to the water.
- the position of the pilot is modified to visualize the marine space.
- the nacelle N will participate in the buoyancy of the boat comprising the two lateral hulls K.
- the hulls K of the boat as well as the structure of the n-boat, which is in contact with the inner sides of the hulls K, may consist for example of composites (polyester, epoxy, glass fiber or carbon or Kevlar) or be made from rotomouldings.
- the weight of the machine according to the materials can approximately oscillate between 90 to 120 kilograms without the propulsion engine.
- the boat also comprises two transverse beams of structure P which make it possible to ensure the connection and the maintenance of the hulls K (FIGS. 13 and 14).
- the mechanism of the movement of the nacelle N is simple. This is articulated on a transverse axis H transfixing the rear end of the nacelle N. This axis can be fixed symmetrically on the rear parts of the inner flanks of the shells K.
- the nacelle N is fixed in a sealed manner to each shell K, via a sealed connection between the axis transfixiant H and the nacelle N, and possibly a tight connection between the axis H and each shell K if the axis H passes through the structure of each hull K.
- the axis H can for example be supported by the hulls K, moving it upwards until it is supported by the gunwale of the hulls K.
- the rear shape of the pod N will be adapted to this solution, and may for example be raised to allow high attachment of this axis.
- the device comprises, in addition to the n-boat, deployment means C, H and fastening means b1, b2, Y, b.
- the front part of the nacelle is supported by a hoist C.
- Said hoist C provides the connection between the front part of the nacelle and the beam P connecting before the hulls of the machine.
- the guidance system H is the transfixing axis in this embodiment.
- a fixing means b1, b2, Y, b, of the n-pod N in the low position PB is provided in order to prevent relative movement of the n-boat with respect to the boat and thus improve the stability of the machine.
- the fastening means may be made for example by a tubular spacer fixed to the front part of the nacelle and to the structural beam, the attachment of which could be adjusted so as to be able to vary the depth of the nacelle N.
- the low position PB can correspond to the position determined in the water Ci and the high position PH can correspond to the determined position out of the water c 2 .
- the first deployment means C, H also makes it possible to move the support T between the position outside the water C2 and the position determined under the water Ci, the fixing means b1, b2, Y, b, allowing the maintenance of the support T in the position out of the water C2.
- the weight of the n-boat is neutral, ie the n-boat can not sink or float completely. This is achievable for example by adding polystyrene in the nacelle's own structure.
- the front part of the platform has a V shape to attack the waves at best. It also has flanges on its sides which are an integral part of the nacelle and are against the inner flanks of the hulls K. This serves on the one hand to maintain more stable N pod in high position PH, but also to avoid splashing.
- the nacelle comprises for example a seat S.
- the machine as described in Figures 11, 12, 13 and 14 is provided for a user. However, it is possible to expand the n-pod so that other users can stick to it as well.
- the machine is therefore intended for one or more users depending on its width.
- the device can be easily mounted on the boat by assembling thereto, on each side, the axis and then linking the front part of the n platform N to hoist C.
