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 exceptional in the past.

[0004] In certain parts of the world, there is an increasing frequency of heavy rainfall, during which a large quantity of water falls in a very short time and in a localized manner. During such heavy rainfall, waterways overflow rapidly and sewage drainage capacities are quickly overwhelmed. This results in flash floods and also sudden inundations of areas that may be inhabited and / or support buildings.

[0005] We also observe very long rainy episodes leading to rises in water levels which, although gradual, eventually result 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 remains relevant. This is the need to make progress in the fight against flooding.

[0008] In patent GB 2477365 B, a roller shutter is proposed for installation under a door landing to act as a barrier against water in the event of flooding. A passage for the shutter is provided in the door landing. This passage allows the shutter to extend and rise between two tracks. When the roller shutter is retracted under the door landing, this passage is closed by a latch over which, for years, everything entering or exiting through the door walks or rolls. Most of the time, this latch becomes dirty and / or deteriorates in such a way that it prevents the roller shutter from deploying correctly when, sometimes after years of inactivity, it needs to extend and rise between the two tracks to act as a barrier against flooding. water. Summary of the invention

[0009] A flood protection device comprises a gate that pivots about an axis of rotation and a gate actuating motor. A motor rotor is configured to interact electromagnetically with a motor stator so that it is pivoted about itself relative to the stator when the motor is activated. The gate is immobilized or lockable, at least in terms of rotation relative to the motor rotor.

[0010] Preferably, a lock is provided such that, when the leaf is in a closed position, it can be secured to a fixed structure in order to better resist the pressure of water in the event of flooding. Brief description of the figures

[0011] Other advantages and features will become clearer from the following description of a particular embodiment of the invention, given by way of non-limiting example and shown in the accompanying drawings, among which:

[0017] [Fig.6] is a perspective view which represents part of the protection device visible on [Fig.l] and which shows two bolts locking a free edge of the leaf to a low wall while the leaf is in its closed position. Description of the implementation methods

[0018] In [Fig. 1], a parking and / or property entrance comprises a fixed structure consisting of two low walls 1 spaced apart. The parking and / or property entrance further comprises a roadway 2 between the two low walls 1.

[0019] Still on [Fig. 1], the parking and / or property entrance is equipped with a A protection device 10 according to an embodiment of the invention. The protection device 10 is a flood protection device.

[0020] A leaf 11 of the protective device 10 is articulated to a subassembly 12 so as to pivot 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 on [Fig. 1].

[0021] The two walls 1 delimit between them a passage which 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 exit it.

[0022] The subassembly 12 includes a lateral upright 13, which is fixed to the inner wall of one of the walls 1, for example by screws 15 (see [Fig. 4]). As can be seen in [Fig. 1], a rain and snow cover 14 is fixed to one upper end of the upright 13.

[0023] In [Fig.2], subassembly 12 is shown without the protective cover 14. Subassembly 12 includes 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 in a top plate 17 of this sealed housing 20. An annular seal, not shown for clarity, is fitted to the top plate 17 and surrounds the output shaft 22. This annular seal provides a water and dust seal between the output shaft 22 and the top 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 globally at a right angle to the output shaft 22, for example by welding.

[0026] A locking device 24 connects the support arm 23 and a mounting plate 25, which is carried by this support arm 23. The locking device 24 is known per se and is not described in detail here. The locking device 24 is switchable between a locked position and an unlocked position. When the locking device 24 is in its locked position, the mounting plate 25 is rigidly coupled to the support arm 23. When the locking device 24 is in its unlocked position, the mounting plate 24 can pivot about the Z-axis of rotation, relative to the support arm 23.

[0027] According to a first embodiment of the invention, the locking device 24 is removed, and the assembly plate 25 is rigidly fixed to the support arm 23 or forms this support arm 23.

[0028] According to a second 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 embodiment of the invention combines the first and second embodiments of the invention.

[0030] In [Fig. 3], a portion of the leaf 11 is visible. This is the portion to be assembled to sub-assembly 2. As can be seen in [Fig. 3], a lower crossbar of the leaf 11 has several holes 27 for the passage of screws and bolts 28 (see [Fig. 4]), which are bolts for fixing a lower corner of the leaf 11 to the assembly plate 25. An upper crossbar of the leaf 11 carries an upper pivot 29, which is directed upwards so that the bearing 21 can be threaded onto this upper pivot 29 from above.

[0031] In [Fig.4], the leaf 11 is mounted on the sub-assembly 12. In [Fig.4], the bolts 28 fix the leaf 11 to the assembly plate 24.

[0032] Still on [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 sub-assembly 12 so as to be pivotable 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 a variant of the invention, the upper pivot 29 is a fixed part of the hinge 30 by being fixed for example to the upright 13, while the bearing 21 is a pivoting part of the hinge 30 by being fixed to the leaf.

[0034] As can be seen in [Fig.4], the axis of rotation Z is close to the wall 1 supporting the upright 13. This allows the sub-assembly 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 as 35. The motor 35 comprises a stator 36 which is fixed 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 axis of rotation 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 generated and produce a pivoting torque of the stator 36 on itself, relative to the rotor 37.

[0037] The output shaft 22 is part of the rotor 37. The motor 35 forms a hinge that articulates the leaf 11 to the stator 36 and the sealed housing 20. Called the first hinge, this hinge formed by the motor 35 is a lower hinge that 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 locked hinge in the absence activation of motor 35. In other words, the hinge formed by motor 35 is a hinge that can be unlocked by activating motor 35. According to one embodiment of the invention, the hinge formed by motor 35 is a free hinge. A free hinge is understood to be an unblocked hinge whose pivoting part can pivot freely 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 concrete bearing. The sealed housing 20 encloses the stator 36 of the motor 35 in a manner that is watertight and dustproof. 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 pavement 2 in the example shown. Except for a portion 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 pavement 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 control and driving unit for 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 status 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 (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], reference numeral 48 designates a cellular phone with a microprocessor, which is capable of sending a command 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 bracket 50 of the protective device 10 is fixed to the wall 1 not supporting the upright 13 of the subassembly 12. Opposite the axis of rotation Z, the leaf 11 has a free edge, which two bolts 52 of the retractable bolt type are able to lock to the angle bracket 50 and the corresponding wall 1, when the leaf 11 is in its closed position.

[0043] The protective device 10 includes several sealing gaskets, which are not shown for clarity. The subassembly 12 and the leaf 11 each carry one or more of these sealing gaskets. When the leaf 11 is in its closed position, the sealing gaskets ensure that the protective device 10 closes in a generally watertight manner the passage between the two 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 gate 11 begins with the issuance of a "flood" alert, for example, by a state weather service or another official or private service. The cell phone 48 or another device with a microprocessor receives this alert, based on which a user chooses whether or not to send a command to close the gate 11. To issue this command to close the gate 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 swing 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 lock the leaf 11 together in its closed position.

[0046] When the gate 11 is in its closed position, as shown in [Fig. 1], the protective device 10 provides a generally watertight seal to the passage between the two walls 1, over the entire height of the gate 11 from the roadway 2, or at least over a portion of the height of the gate 11 from the roadway 2. If flooding occurs from the area outside the two walls 1 while the gate 11 is in its closed position, the protective device 10 prevents, at least in most respects, this flooding from entering the passage between the two walls 1. Description 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 goal is achieved by means of a flood protection device, which includes a leaf pivoting around an axis of rotation and a motor for actuating the leaf around 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 motor rotor.

[0049] To prevent a pivoting door leaf from closing off a passage, this leaf can simply be placed in the open position, resulting in reliable and robust operation.

[0050] The protective device according to the invention has the advantage that the axis of rotation can be close to one of the two sides of an opening that the gate allows to be closed. Thanks to this, the protective device according to the invention can occupy only a very small part of the width of this opening when the gate is in the open position.

[0051] The protection device defined above may incorporate one or more other advantageous features, alone 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 a smaller footprint can be achieved. The fixed support may include, for example, one or more elements such as a floor, a roadway, and a fixed structure such as a landing and / or a low wall.

[0054] According to an advantageous possibility, the hinge formed by the motor is a hinge supporting the leaf.

[0055] Thus, a simplification and / or a smaller footprint 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, a smaller lateral footprint can be obtained.

[0060] According to an advantageous possibility, the stator and at least part of the rotor are housed in a hollow in the ground.

[0061] Thus, the bulk of the external part of the protection device can be less and / or sensitive parts of the engine can be well protected against many shocks such as those resulting from a collision with a vehicle.

[0062] According to an advantageous possibility, the second hinge is a top hinge which has 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 protective device can be facilitated.

[0064] According to an advantageous possibility, the pivoting part of the second hinge is a top 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 watertight manner.

[0066] Thus, sensitive parts of the engine can be well protected, for example against the weather.

[0067] According to an advantageous possibility, the protection device includes 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 force without opening. For example, such a force could be the force 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 includes a motor control unit from a command, as well as a receiver configured to communicate remotely with a transmitter of the command and to transfer this command to the control unit.

[0070] Thus, the closing of the leaf can be controlled remotely.
