Abstract
Description
Title of the invention: FLOOD PROTECTION DEVICE Technical field of the invention
[0001] The present invention relates to a flood protection device.
[0002] For example, the invention can be applied to the protection of an individual or collective garage as well as to the protection of a property enclosed by a low wall or to the protection of a residential or other building, in the event of a flood such as a flood resulting from a flash flood. State of the art
[0003] Global warming is accompanied by an increase in the quantity and severity of extreme weather events, which were once exceptional.
[0004] In some parts of the world, there is an increasing incidence of heavy rains, in which a large amount of water falls in a very short time and in a localized manner. During such heavy rains, rivers quickly overflow and the drainage capacities of sewers are quickly exceeded. This results in flash floods and also flash flooding of areas that may be inhabited and / or have buildings on them.
[0005] There are also very long rainy episodes leading to rising water levels which, although gradual, end up resulting in large-scale flooding.
[0006] Populations are most often truly helpless in the face of such extreme weather events, which can also cause very costly material damage.
[0007] As a result, an old need is still relevant today. It is the need to make progress in the fight against flooding.
[0008] In patent GB 2477365 B, a roller shutter is proposed to be installed under the landing of a door to act as a barrier against water in the event of flooding. A passage for the shutter is provided in the landing of the door. This is a passage through which the shutter can come out to be erected between two slides. When the roller shutter is retracted under the landing of the door, this passage for the shutter is closed by a closure on which, for years, everything entering or leaving through the door walks or rolls. Most of the time, this closure is therefore dirty and / or damaged in a way that prevents the roller shutter from being deployed correctly on the day when, sometimes after years of inactivity, the shutter must come out and be erected between the two slides to act as a barrier against water. Summary of the invention
[0009] A flood protection device comprises a leaf pivoting about an axis of rotation and a motor for actuating the leaf. A rotor of the motor is configured to be in electromagnetic interaction with a stator of the motor so as to be pivoted on itself relative to the stator when the motor is activated. The leaf is immobilized or lockable at least in rotation relative to the rotor of the motor.
[0010] Preferably, a lock is provided such that, when the leaf is in a closed position, it can be secured to a fixed construction to be able to better resist the pressure of water in the event of flooding. Brief description of the figures
[0011] Other advantages and characteristics will emerge more clearly from the following description of a particular embodiment of the invention, given by way of non-limiting example and shown in the appended drawings, among which:
[0012] [Fig-1] is a partial perspective view of a parking lot or property entrance equipped with a flood protection device according to one embodiment of the invention,
[0013] [Fig.2] is a perspective view, partially exploded, of a subassembly which is configured to pivot a leaf and which constitutes the protection device visible in [Fig.l],
[0014] [Fig.3] is a partial perspective view of a leaf which is configured to be mounted on the subassembly of [Fig.2] and which constitutes the protection device shown in [Fig.l],
[0015] [Fig.4] is a partial perspective view, in which the leaf represented by initially on [Fig.3] is mounted on the subassembly shown in [Fig.2],
[0016] [Fig.5] is a diagram of which a part is a schematic section along the plane V re presented in [Fig.4] and which shows in particular the embedding of the motorization and a control chain, and
[0017] [Fig.6] is a perspective view showing part of the protective device visible in [Fig.l] and which shows two locks locking a free edge of the leaf to a low wall while the leaf is in its closed position. Description of the embodiments
[0018] In [Fig.l], a parking and / or property entrance comprises a fixed construction of which two low walls 1 are at a distance from each other. The parking and / or property entrance further comprises a roadway 2 between the two low walls 1.
[0019] Still in [Fig.l], the parking and / or property entrance is provided with a protection device 10 according to one embodiment of the invention. The protection device 10 is a flood protection device.
[0020] A leaf 11 of the protection device 10 is hinged to a subassembly 12 so as to be pivotable about an axis of rotation Z, between an open position and a closed position. The axis of rotation Z is an upward axis, which is preferably vertical. The leaf 11 is in its closed position in [Fig. 1].
[0021] The two low walls 1 delimit between them a passage that pedestrians, animals such as horses, and / or vehicles such as motor vehicles, including cars, can use to enter a parking lot (not shown) and / or a property (not shown), and / or to leave it.
[0022] The subassembly 12 comprises a lateral upright 13, which is fixed to the inner wall of one of the low walls 1, for example by screws 15 (see [Fig.4]). As can be seen in [Fig.l], a hood 14 for protection against rain and snow is fixed to an upper end of the upright 13.
[0023] In [Fig. 2], the subassembly 12 is shown without the protective cover 14. The subassembly 12 comprises a lower sealed housing 20 and a bearing 21. The bearing 21 is fixed to the upright 13, for example by bolts 16 (see [Fig. 4]).
[0024] An output shaft 22 of a motor described later exits the sealed housing 20 by passing through a hole through an upper plate 17 of this sealed housing 20. An annular seal, not shown for the sake of clarity, equips the upper plate 17 and surrounds the output shaft 22. This annular seal ensures a water and dust seal between the output shaft 22 and the upper plate 17.
[0025] The output shaft 22 has a longitudinal axis which coincides with the axis of rotation Z. A support arm 23 is fixed generally at right angles to the output shaft 22, for example by welding.
[0026] A locking device 24 associates the support arm 23 and an assembly plate 25, which this support arm 23 carries. The locking device 24 is known per se and is not described in detail here. The locking device 24 is switchable between a locking position and an unlocked position. When the locking device 24 is in its locking position, the assembly plate 25 is rigidly coupled to the support arm 23. When the locking device 24 is in its unlocked position, the assembly plate 24 can pivot about the axis of rotation Z, relative to the support arm 23.
[0027] According to a first variant embodiment of the invention, the locking device 24 is omitted, and the assembly plate 25 is rigidly fixed to the support arm 23 or forms this support arm 23.
[0028] According to a second variant embodiment of the invention, a dog clutch couples the output shaft 22 and a lower part of the leaf 11 to each other.
[0029] A third variant embodiment of the invention combines the first and second variant embodiments of the invention.
[0030] In [Fig. 3], a part of the leaf 11 is visible. This is the part to be assembled to the subassembly 2. As can be seen in [Fig. 3], a lower crosspiece of the leaf 11 has several holes 27 for the passage of bolt screws 28 (see [Fig. 4]), which are bolts for fixing a lower corner of the leaf 11 to the assembly plate 25. An upper crosspiece of the leaf 11 carries an upper pivot 29, which is directed upwards so that the bearing 21 can be slipped onto this upper pivot 29 from above.
[0031] In [Fig.4], the leaf 11 is mounted on the subassembly 12. In [Fig.4], the bolts 28 fix the leaf 11 to the assembly plate 24.
[0032] Still in [Fig.4], the upper pivot 29 is engaged in the bearing 21. The bearing 21 and the upper pivot 29 together form a hinge 30 by which the leaf 11 is articulated to the subassembly 12 so as to be tiltable around the axis of rotation Z.
[0033] In the embodiment shown, the bearing 21 is a fixed part of the hinge 30, while the upper pivot 29 is a pivoting part of the hinge 30. According to an alternative embodiment of the invention, the upper pivot 29 is a fixed part of the hinge 30, being fixed for example to the upright 13, while the bearing 21 is a pivoting part of the hinge 30, being fixed to the leaf.
[0034] As can be seen in [Fig.4], the axis of rotation Z is close to the wall 1 carrying the upright 13. This allows the subassembly 12 to occupy only a very small part of the width of the passage between the two walls 1, which is particularly advantageous when the leaf 11 is in the open position.
[0035] In [Fig. 5], the motor mentioned above is referenced 35. The motor 35 comprises a stator 36 which is immobilized relative to the sealed housing 20. The motor 35 comprises a rotor 37, which is pivotable relative to the stator 36, on a pivot axis coinciding with the rotation axis Z. The detailed construction of the motor 35 is known per se and is not described in detail here.
[0036] When the motor 35 is activated, the stator 36 and the rotor 37 are in electromagnetic interaction so that electromagnetic forces are then generated and produce a pivoting torque of the stator 36 on itself, relative to the rotor 37.
[0037] The output shaft 22 constitutes the rotor 37. The motor 35 forms a hinge which articulates the leaf 11 to the stator 36 and to the sealed housing 20. Called the first hinge, this hinge formed by the motor 35 is a lower hinge which supports the leaf 11. Called the second hinge, the hinge 30 is an upper hinge whose pivot axis is generally aligned with the pivot axis of the stator 36. The hinge formed by the motor 35 is a hinge blocked in the absence activation of the motor 35. In other words, the hinge formed by the motor 35 is a hinge that can be unlocked by activation of the motor 35. According to an alternative embodiment of the invention, the hinge formed by the motor 35 is a free hinge. By free hinge is meant an unblocked hinge whose pivoting part can freely pivot relative to the fixed part.
[0038] The sealed housing 20 is mounted in a recess C in a floor S which, for example, is a bearing made of concrete. The sealed housing 20 encloses the stator 36 of the motor 35 in a watertight and dust-tight manner. The stator 36 of the motor 35 is located in the recess C, below the surface of the floor S, i.e. below the upper surface of the roadway 2 in the example shown. With the exception of a part of its output shaft 22, the rotor 37 of the motor 35 is also located in the recess C, below the surface of the floor S, i.e. below the upper surface of the roadway 2 in the example shown.
[0039] The protection device 10 comprises a control unit 40 and a receiver 41, which are connected to each other by a link 42 so as to be able to communicate with each other.
[0040] In the embodiment of [Fig. 5], the control unit 40 is a unit for controlling and controlling the motor 5, to which it is connected by a wired link 43. The wired link 43 is configured to transmit an indication of the state of the motor 35 to the control unit 40. The wired link 43 is also configured to apply a command from the control unit 40 to the motor 35.
[0041] The receiver 41 is capable of receiving commands via wireless communication such as Wi-Fi communication (ISO / IEC 8802-11 standard) with a transmitter 45 connected to the Internet 46. In the embodiment of [Fig. 5], the receiver 41 is also a transmitter capable of sending information to the transmitter 45, which is also a receiver. In [Fig. 4], the reference 48 designates a cellular telephone with a microprocessor, which is capable of sending an order to the transmitter 45 via the Internet 46.
[0042] In [Fig. 6], the leaf 11 is in its closed position, as in [Fig. 1]. As can be seen in [Fig. 6], an angle iron 50 of the protection device 10 is fixed to the wall 1 not carrying the upright 13 of the subassembly 12. Opposite the axis of rotation Z, the leaf 11 has a free edge, which two locks 52 of the retractable bolt type are able to lock to the angle iron 50 and to the corresponding wall 1, when the leaf 11 is in its closed position.
[0043] The protection device 10 comprises several seals which are not shown for the sake of clarity. The subassembly 12 and the leaf 11 each carry one or more of these seals. When the leaf 11 is in its closed position, the seals ensure that the protection device 10 closes in a generally watertight manner the passage between the two low walls 1, over the entire height of the leaf 11 from the roadway 2 or over at least the majority of the height of the leaf 11 from the roadway 2.
[0044] An example of a command leading to the closing of the leaf 11 begins with the issuance of a “flood” alert, for example, by a state weather office or other official or private service. The cellular telephone 48 or another device comprising a microprocessor receives this alert, on the basis of which a user chooses whether or not to send an order to close the leaf 11. To issue this order to close the leaf 11, the user can use the device that previously received the “flood” alert. For example, the user uses the cell phone 48 to issue the order to close the leaf 11. The order to close the leaf 11 is sent to the control unit 40, via the Internet 46, then via the transmitter 45 and then via the receiver 4L. Following receipt of the order to close the leaf 11, the control unit 40 activates the motor 35 to make it tilt the leaf 11 from its open position to its closed position.
[0045] The locks 52 are configured to detect whether the leaf 11 is in its closed position. When they have detected that the leaf 11 is in its closed position, the locks 52 actuate themselves to a state in which they together lock the leaf 11 in its closed position.
[0046] When the leaf 11 is in its closed position as is the case in [Fig. 1], the protection device 10 closes in a generally watertight manner the passage between the two low walls 1, over the entire height of the leaf 11 from the roadway 2 or over at least part of the height of the leaf 11 from the roadway 2. If flooding occurs from the area outside the two low walls 1 while the leaf 11 is in its closed position, the protection device 10 at least essentially prevents this flooding from entering the passage between the two low walls 1. Presentation of the invention
[0047] The invention has at least the aim of improving the reliability of a flood protection device.
[0048] According to the invention, this aim is achieved by means of a flood protection device, which comprises a leaf pivoting about an axis of rotation and a motor for actuating the leaf about the axis of rotation, the motor comprising a stator and a rotor which is configured to be in electromagnetic interaction with the stator so as to be pivoted on itself relative to the stator when the motor is activated, the leaf being immobilized or lockable at least in rotation relative to the rotor of the motor.
[0049] So that a pivoting leaf does not close a passage, this leaf can simply be placed in the open position, resulting in reliable and robust operation.
[0050] The protection device according to the invention has the advantage that the axis of rotation can be close to one of the two sides of a passage that the leaf allows to be closed. Thanks to this, the protection device according to the invention can occupy only a very small part of the width of this passage when the leaf is in the open position.
[0051] The protection device defined above may incorporate one or more other advantageous characteristics, individually or in combination, in particular among those defined below.
[0052] According to an advantageous possibility, the motor forms a hinge for articulating the leaf to a support.
[0053] Thus, simplification and / or reduced bulk can be achieved. The fixed support may comprise, for example, one or more elements from a floor, a roadway and a fixed construction such as a landing and / or a low wall.
[0054] According to an advantageous possibility, the hinge formed by the motor is a hinge for supporting the leaf.
[0055] Thus, simplification and / or reduced bulk can be achieved.
[0056] According to an advantageous possibility, the hinge formed by the rotor is a hinge inferior.
[0057] According to an advantageous possibility, the hinge formed by the motor is a first hinge, the protection device comprising a second hinge for articulating the leaf to a support.
[0058] According to an advantageous possibility, the stator and at least part of the rotor are lower than the leaf.
[0059] Thus, less lateral bulk can be obtained.
[0060] According to an advantageous possibility, the stator and at least part of the rotor are housed in a hollow in a ground.
[0061] Thus, the bulk of the external part of the protection device can be reduced and / or sensitive parts of the engine can be well protected against numerous shocks such as those resulting from a collision with a vehicle.
[0062] According to an advantageous possibility, the second hinge is an upper hinge which comprises a fixed part and a pivoting part fixed to the leaf, the fixed part being lowered onto or into the pivoting part.
[0063] Thus, the installation of the protection device can be facilitated.
[0064] According to an advantageous possibility, the pivoting part of the second hinge is an upper pivot which is fixed to the leaf so as to be directed upwards.
[0065] According to an advantageous possibility, the protection device comprises a sealed housing enclosing the stator and at least part of the rotor in a waterproof manner.
[0066] Thus, sensitive parts of the engine can be well protected, for example against bad weather.
[0067] According to an advantageous possibility, the protection device comprises a lock shaped to secure, at a distance from the axis of rotation, the leaf to a fixed construction when the leaf is in a closed position.
[0068] Thus, the leaf in its closed position can withstand a significant thrust without opening. For example, such a thrust may be the thrust of water present only on one side of the leaf, for example in the case of a flood.
[0069] According to an advantageous possibility, the protection device comprises a unit for controlling the motor based on an order, as well as a receiver configured to communicate remotely with a transmitter of the order and to transfer this order to the control unit.
[0070] Thus, the closing of the leaf can be controlled remotely.
