Description

SOLAR FLOAT WITH A SELF-LOCKING CAP The present invention relates to a float for use in a floating support structure for supporting at least one solar panel on a body of water.
Such floats for instance comprise a hollow buoyant body and an opening debouching in said hollow body. For creating a floating device or body, said opening is closed by a cap, which can be connected to the hollow body using a suitable connection mechanism, for instance cooperating threading on the cap and the opening.
Such a float may for instance be made from high-density polyethylene, e.g. by injection moulding, and, after application of the cap, can be assembled into rows to support solar panels above water. The floats can further be assembled to assist in creating a pathway for a person to walk on the floating support structure. This pathway can be used for maintenance and buoyancy of the floating support structure. As such, the solar panels and the support structure can be mounted and are accessible for maintenance and cleaning. A problem of known floats is the limited lifetime of the floats, in particular of the connection between the hollow body and the cap resulting in loosening of the cap. A further issue is that assembly of the floats during production while ensuring proper sealing. It is an aim, next to other aims, of the invention to solve or at least alleviate one or more of the aforementioned problems and/or to general provide an improved float. To that end, a float according to claim | is provided. More specifically, a float is provided for use in a floating support structure for supporting at least one solar panel on a body of water, the float comprising a hollow buoyant body, an opening debouching in said hollow body, a cap and a connection mechanism arranged for connecting the cap to the buoyant body for closing the opening in a closed position, wherein the float further comprises a self-locking mechanism configured to prevent disconnection of the cap from the float. Preferably, the self-locking mechanism is arranged to maintain the cap in said closed position, i.e. the position wherein the cap seals the opening. It was found that loosening of the cap may be the result of temperature changes in the float and particularly in the material of the float. Over time, the temperature changes and the resulting thermal expansion and contraction of the material can lead to a loosening of the sealing of the float and to water infiltrating a float and thus to a limited lifetime of the floating support structure. The self-locking mechanism is preferably arranged to prevent disconnection of the cap from the connection mechanism in the closed position. Accordingly, the aforementioned problems relating to the loosening of a cap on a float may be at least partially solved. With a self-locking mechanism, the cap can be securely connected to the buoyant body in a self-locking manner such that preferably no additional locking would be needed.
Further, the process of producing the floats is optimized. It was found that the production is in particular time-consuming due to the fact that sealing of a float must wait until after the cooling process to prevent an improper sealing. Due to cooling, the hollow body may change in size, specifically decrease, resulting in less optimal sealing. By providing a self-locking mechanism, losing the cap is prevented. Because the sealing of the floats can already be done during the cooling process, sealing the floats during the cooling process allows a faster production of floats. Furthermore, sealing the floats during the cooling process increases the throughput of float production, thereby limiting the capacity needed for producing the floats.
The float, cap and the hollow body as described are particularly suitable for use in a floating support structure for supporting at least one solar panel. Such a support structure may comprise a plurality of floating support elements, each for supporting a panel, wherein the floating support elements are and the floats, optionally next to other components, may form the support structure as mentioned.
It is however noted that the invention is not limited to support structures for solar panels. The float, hollow body and/or cap may also be used in other floating structures, for instance to form bridges, artificial islands, pontoons or jetties, wherein said floating structures may be formed by interconnecting, using suitable coupling means, a plurality of floats as described.
According to an embodiment of the float, the self-locking mechanism comprises one or more locking members. Locking members can be used to mechanically lock the cap onto the buoyant body. For example, the one or more locking members may be bulges, vanes and/or flanges. The locking members can be arranged to be moved into at least one corresponding lock during the connecting of the cap. A lock may be, for example, a notch, a nock, a gap or a sleeve. The lock is then arranged to e.g. catch, envelop, hook and/or clamp a locking member to prevent loosening of the cap.
Preferably, the one or more locking members are provided on the cap. By providing the one or more locking members on the cap, a locking member can be moved into a corresponding lock during the connecting of the cap. For example, a locking member may be moved into a lock with the same movement as the connecting of the cap. This enables a quick and convenient locking of the cap. Alternatively, a locking member may be moved into a lock with a different movement than the connecting of the cap. For example, the connecting and locking of the cap may then comprise a two-step movement, wherein the connecting is a movement of a first degree of freedom and the locking is a movement in a second degree of freedom. This may enable a more secure locking of the cap. The connecting and locking of the cap may also be a multi-step movement, wherein the plurality of steps is preferably more than two. According to a further embodiment, the self-locking mechanism comprises at least one deformable locking member which is movable between an unlocked position, wherein the cap is movable with respect to the buoyant body in a connection direction, and a locked position, wherein movement of the cap is blocked along said connection direction. By being in an unlocked position when the cap is moved in the connection direction, the locking member does not obstruct the connecting of the cap. In the locked position of the locking member, a cap in the closed position is prevented from disconnecting. Preferably, the locking member is biased towards the locked position. A bias of the locking member towards the locked position contributes to the self-locking capacity of the float, because no additional step of moving the locking member towards the locked position would be needed. 1t is then further preferred if the locking member can be moved towards the unlocked position during the moving of the cap in the connection direction. For example, the moving of the cap in the connection direction may move the locking member towards the unlocked position. According to a further embodiment, the self-locking mechanism comprises at least one pair of a deformable locking member and an engagement member arranged to engage the deformable member in the locked position, wherein the deformable locking member is provided on the cap or the float, wherein the engagement member is arranged on the other of the cap or the float. The engagement member can be used to mechanically lock the cap onto the buoyant body. The engagement member can be arranged to engage the at least one corresponding locking member during the moving of the cap in the connection direction. The locking member may then be arranged to e.g. catch, envelop, hook and/or clamp an engagement member to prevent loosening of the cap in the closed position. Preferably, at least one of the locking members is arranged to abut at least one engagement member after connecting the cap onto the buoyant body.
Further, the cap may comprise at least one deformable locking member, preferably a plurality thereof. By arranging one or more locking members on the cap to abut one or more engagement members on the buoyant body, the locking member and engagement member can lock the cap correspondingly.
For example, an engagement member on the buoyant body may catch or hook a locking member on the cap after connecting the cap onto the buoyant body.
Furthermore, by providing the deformable member on the cap, the cap and the deformable member can be integrally made.
The cap comprising the deformable member differs in functionality from the buoyant body, which functions to provide e.g. buoyancy and stability.
According to a further embodiment, the cap comprises a plate shaped base member with a raised edge or collar for engaging the connection mechanism.
In the closed position, the plate shaped base member can seal the opening of the hollow buoyant body.
The raised edge of the base member can engage the connection mechanism for a further sealing of the opening and for securing the cap onto the buoyant body.
A further sealing is achieved if the raised edge engages the connection mechanism with a large surface area of the raised edge.
For example, the raised edge may be a raised outer edge of the plate shaped base member.
The surface area of the raised edge can then be relatively large.
Alternatively, the plate shaped base member has a centric protrusion protruding from a plane of the plate, the centric protrusion being arranged centrically of the plate and away from the edge of the plate and arranged to engage the connection mechanism.
According to a further embodiment, the buoyant body comprises a neck being a raised edge around the opening of the buoyant body, wherein the neck comprises the connection mechanism.
By having a neck, the buoyant body can connect with the cap through the connection mechanism.
Because the neck is a raised edge, the connection mechanism can be provided along the surface area of the neck for a secure connection of the cap onto the buoyant body.
For example, the edge around the opening may be raised in an outward direction away from the buoyant body.
The cap can then engage with the connection mechanism on the outside of the buoyant body.
Alternatively, the edge may be raised inwardly such that it is at least partially provided inside the hollow buoyant body.
According to a further embodiment, the raised edge of the cap and the neck of the buoyant body are annular.
Because the raised edge and the neck are similarly shaped, the cap can be suitably fitted onto the buoyant body and engage the connection mechanism provided on the neck.
A suitable fit of the cap and the neck prevents water from entering the float.
The suitable fit further enables a secure connecting of the cap onto the buoyant body.
The annular shape allows the cap to slide onto the neck for easily closing the opening of the buoyant body.
Preferably, the raised edge may be annular with an inner diameter corresponding to an outer diameter of the annular neck for a further secure connecting of the cap onto the buoyant body. The corresponding diameters preferably contribute to preventing water from entering the float. The cap then envelops the neck when closing the opening of the buoyant body and engaging the connection 5 mechanism. The connection mechanism may then be arranged between the connected cap and the neck. Alternatively, the centric protrusion of the cap and the neck may be annular. An outer diameter of the annular protrusion may then correspond to an inner diameter of the annular neck. According to a further embodiment, the connection mechanism comprises threading for screwing the cap onto the buoyant body. By screwing the cap onto the buoyant body, the cap can be securely connected to the buoyant body. For example, the threading may be provided along the neck of the buoyant body and/or the threading may be provided on the cap. Preferably, the connecting mechanism comprises cooperating threading provided on the cap and a neck around the opening of the buoyant body.
According to a further embodiment, the self-locking mechanism is configured to counter any rotation in the closed position. It is then further preferred if threading is arranged for connecting the cap to the buoyant body by rotating the cap in a first direction, wherein the self-locking mechanism is arranged (o prevent rotation of the cap in a direction opposite the first direction. The cap can then only be moved to the closed position and is prevented from disconnecting when rotating from the closed position in the direction opposite the first direction. The cap can then be moved to the closed position already during the cooling process during production of the float. In case the cap has loosened after connection during the cooling process, the cap can be easily rotated further in the first direction for a more secure connection of the cap onto the buoyant body, after which the cap remains in the closed position in a self-locking manner by means of the self-locking mechanism. In unlocked position, the deformable member is preferably arranged to allow rotation in the first direction, wherein in the locked position, the deformable member blocks rotation in the direction opposite the first direction. No additional step is then needed for moving the deformable locking member to the unlocked position when rotating the cap in the first direction. Similarly, no additional step would be needed to move the deformable locking member to the locked position when rotating the cap in the direction opposite the first direction.
According to a further embodiment, the neck comprises external treading and wherein the cap comprises a plate shaped base member with a raised edge provided with internal threading. The threading on the cap then corresponds to the threading on the neck.
Further, the cap envelops the neck when closing the opening of the buoyant body and engaging the threading.
The threaded connection mechanism preferably contributes to preventing water from entering the float.
For example, the threading is provided on a radially inner surface of the raised edge of the cap and on a radially outer surface of the neck.
Alternatively, threading on the cap may be provided on a radially outer surface of the centric protrusion and threading on the neck may be provided on a radially inner surface of the neck.
According to a further embodiment, the at least one locking member is provided on the raised edge of the cap.
Because the raised edge is relatively close to the buoyant body in comparison with the plate shaped base member of the cap, a locking member provided on the raised edge can conveniently lock the cap onto the buoyant body.
Preferably, the at least one locking member may be provided on a radially outer surface of the raised edge of the cap.
A locking member on the cap can then be visibly moved into a locking position.
For example, a locking member may be moved into a lock or a locking member may be moved to abut an engagement member on the buoyant body for catching or hooking the locking member.
Preferably, a plurality of locking members extends radially from the outer surface of the cap, wherein the locking members extend under an angle with respect to the normal, i.e. are arranged skewed.
The locking members are preferably arranged as barb or hook shaped members, to prevent rotation in a direction opposite the first (connection) direction as defined by the threading in the cap.
Alternatively, the at least one locking member may be provided on a radially inner surface of the raised edge of the cap.
According to a further embodiment, the at least one locking member is skewed for flattening under the influence of the at least one engagement member during the connecting of the cap.
By being skewed, the at least one locking member on the cap can flatten in the direction in which the at least one locking member leans askew.
Preferably, a locking member is skewed in the direction of the movement for connecting the cap onto the buoyant body.
The locking member can then flatten under the influence of an engagement member on the buoyant body during the connecting of the cap to allow movement of the locking member past the engagement member.
When the locking member is moved past the engagement member in the first direction, movement of the locking member in the second direction opposite to the first direction is prevented by the skewed locking member, because the locking member is additionally skewed to straighten under the influence of an engagement member when moved in the second direction, wherein a locking member straightened by an engagement member prevents further movement of the locking member in the second direction. As such, the locking member may function as barb.
Additionally or alternatively, the at least one engagement member may be skewed for flattening under the influence of the at least one locking member during the connecting of the cap. Preferably, the self-locking mechanism is separate form the connecting mechanism, for instance in the form of threading as mentioned above. It may however also be possible that the threading comprises a varying crest, root, flank and/or angle for a self-locking of the cap after connecting. According to a further preferred embodiment, the buoyant body comprises a coupling mechanism configured to interconnect with an adjacent component, for instance a float according to any of the preceding claims, in the floating support structure.
Preferably, the shape of the hollow body is a parallelepiped, preferably rectangular cuboid. This allows efficient coupling of a plurality of floats for providing the floating support structure for supporting at least one solar panel. Easy coupling is obtained if, according to a preferred embodiment, the hollow body is provided with coupling mechanisms near the corners for coupling to neighbouring floats. The coupling mechanism may comprise flanges provided with holes for receiving coupling means, such as screws. Preferably, the flanges extend from the corners of the cuboid.
According to a further embodiment, the float further comprises a protrusion-notch mechanism for an aligned stacking of a first float with an upper surface and at least a second float with a lower surface, wherein the protrusion-notch mechanism comprises one or more notches provided on one of the lower surface and the upper surface, the protrusion-notch mechanism further comprising one or more protrusions provided on the other of the lower surface and the upper surface and arranged to engage the one or more notches. This prevents a relative movement of the floats in a plane parallel to an interface of the first float and the second float.
According to a further embodiment, one or more protrusions are cruciform and the one or more notches are shaped correspondingly. It should be mentioned that the protrusion-notch mechanism may also be applied in floats not having a self-locking mechanism as described above.
According to a further aspect, a cap is provided for use in a float according to any of the preceding claims, comprising a plate shaped base member with a raised edge and locking members provided on the raised edge.
According to a further aspect, a hollow buoyant body for use in the float is provided. The body may be provided with the locking member and/or the engagement member and/or the protrusion- notch mechanism as described above.
According to yet another aspect, a method is provided for manufacturing a float as described above, comprising the steps of providing the hollow buoyant body, providing the cap and connecting the cap to the buoyant body. For example, the hollow buoyant body may be made by injection moulding using a mould for the hollow buoyant body. The injection moulding process takes place e.g. at a temperature between 400 and 500 kelvin. Furthermore, the cap may be made by injection moulding using a mould for the cap. The step of providing the hollow buoyant body preferably includes a cooling process for cooling the buoyant body. Preferably, the cap is connected to the buoyant body during the cooling process. By connecting the cap to the buoyant body during the cooling process, assembly of the float is less time-consuming. The process of producing the floats is thus optimized, because the sealing of the floats can already be done during the cooling process. Sealing the floats during the cooling process allows a faster production of floats. Furthermore, sealing the floats during the cooling process increases the throughput of float production, thereby limiting the capacity needed for producing the floats. The present invention will hereafter be elucidated with reference to the attached drawings, wherein: — Figure 1 shows a float with a cap connected to the hollow buoyant body of the float; - Figure 2 shows an exploded view of a cap with the opening of a hollow buoyant body; - Figure 3 shows a view of the cap in the closed position; - Figure 4 shows a cutaway view of a cap connected to a hollow buoyant body along a diameter of the cap; and - Figure 5 shows two stacked floats.
In figure 1 a float 100 is shown comprising a cap 1 connected to a hollow buoyant body 2.

In the locked position, the deformable member 13 blocks rotation in the direction L opposite the first direction R. The deformable locking members 13 are skewed in the opposite direction L to flatten (in a direction indicated in figare 3 by arrow F) under the influence of one or more engagement members 30 during rotation of the cap 1 in the first direction R.
