By the way, in the above-mentioned Patent Document 1, although it is not specifically specified what kind of type and structure the emergency power supply 45 is, it can be used instead of the commercial power supply AC in an emergency when a power failure occurs. The more various types of emergency power sources can be used, the more convenient they are to use.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a power supply switching device for a switchgear that allows various second power supplies to be used in place of the first power supply in an emergency such as a power failure.

A power supply switching device for a switching device according to the present invention comprises an opening/closing body that can be freely opened/closed, a driving device for driving at least the opening/closing body, and a first power source for supplying power to the driving device in normal times. A power source for a switchgear comprising: a power source; a second power source for supplying power to the drive device in an emergency; and a selector switch for switching from the first power source to the second power source in an emergency. The switching device is characterized in that the second power supply is a generator and/or a storage battery mounted on the vehicle.

In the present invention, the second power supply for supplying electric power to the drive device in an emergency is one that is always prepared at the installation location of the switchgear, the vicinity thereof, a warehouse, etc. ), but a generator and/or storage battery mounted on the vehicle.

Therefore, according to the present invention, various second power sources can be used in place of the first power source in an emergency when a power failure occurs. That is, according to the present invention, as for the second power supply that can be used in place of the first power supply in an emergency when a power failure occurs, in addition to the one that is always available, the one mounted on the vehicle can also be used. become able to.

In addition, according to the present invention, since it is not necessary to keep the second power source in or near the switchgear, installation and storage costs of the second power source can be reduced.

In the present invention, the first power source may be a commercial power source or a power generator capable of supplying power for a long period of time (for example, a diesel power generator, a gasoline power generator, a solar power generator, a wind power generator, etc.). On the other hand, the second power supply mounted on the vehicle may be the above-mentioned generator (it is not always necessary to be able to supply power for a long time), or a storage battery capable of supplying power for a long time (the above-mentioned generator ) or both of them.

Moreover, in the present invention, the second power source may be movable from the vehicle or may be immovable.

According to the former case, in an emergency, when the vehicle cannot be moved to the installation location of the switchgear, the vehicle is temporarily stopped near the installation location of the switchgear, and then the vehicle is mounted on the vehicle. Operation of moving the second power supply to the installation location of the switchgear becomes possible.

Further, according to the present invention, when a plurality of switchgears are installed at the site, it is necessary to always prepare a second power source dedicated to each switchgear inside or near each switchgear. Therefore, it is possible to share (in other words, reuse or branch) the second power supply mounted on the vehicle with a plurality of switchgears. As a result, the installation cost and storage cost of the second power supply can be greatly reduced.

In the present invention, the number of second power sources installed in the vehicle may be one or plural.

In the present invention, the vehicle may be any vehicle as long as it can be equipped with a generator and/or storage battery. Alternatively, it may be an emergency vehicle such as a fire engine or an ambulance as defined in Article 13, Paragraph 1 of the Enforcement Order of the Road Traffic Act, or an ordinary vehicle.

In addition, the special motor vehicle specified in Table 1 of the Enforcement Regulations of the Road Transport Vehicle Act includes shovel loaders, tire rollers, road rollers, graders, road stabilizers, scrapers, rotary snow plows, asphalt finishers, and tire dozers. , motor sweepers, dampers, wheel hammers, wheel breakers, fork lifts, fork loaders, wheel cranes, straddle carriers, turret-type industrial transport vehicles, vehicles with a structure in which the vehicle chassis is bent and steered , Vehicles with caterpillar structures designated by the Minister of Land, Infrastructure, Transport and Tourism and vehicles with special structures designated by the Minister of Land, Infrastructure, Transport and Tourism, agricultural tractors, agricultural chemical spray vehicles, reaping and threshing vehicles, rice transplanters and those designated by the Minister of Land, Infrastructure, Transport and Tourism These include vehicles for agricultural work, pole trailers, and vehicles with special structures designated by the Minister of Land, Infrastructure, Transport and Tourism.

In the present invention, the vehicle may be a gasoline vehicle, a diesel vehicle, an electric vehicle, a fuel cell vehicle, a hybrid vehicle, or the like. Here, when the vehicle is an electric vehicle or a fuel cell vehicle, the energy source of these vehicles is a lithium-ion battery or a fuel cell (a storage battery capable of supplying power for a long time, which is installed in the vehicle as described above). different batteries) itself may be used as the second power supply.

In addition, when the secondary power source is a storage battery mounted on the vehicle that can supply power for a long time, a lithium ion battery of the electric vehicle described above, a fuel cell of the fuel cell vehicle, etc., output from these batteries It is necessary to provide a conversion device (in other words, an inverter) for converting the power supplied from direct current (eg, DC 12V) to alternating current (eg, three-phase AC 200V).

In the present invention, the change-over switch may be arranged at any place. For example, the change-over switch may be housed inside a storage portion for housing the change-over switch formed inside the building frame which is a stationary member. Alternatively, the changeover switch may be housed inside a housing member for housing the changeover switch.

In the latter case, the storage member for storing the changeover switch is provided with an opening for operating the changeover switch from the outside, and this opening can be freely opened and closed by a door that is locked and unlocked by a locking device. It is preferable that the door body is locked and unlocked by operating the key.

Here, the door body that is locked and unlocked by operating the key may be unlockable also by water pressure.

According to this, even in an emergency, for example, when the administrator who manages the key is absent, or when there is no person who knows the storage location of the key, the water pressure will also can be unlocked.

Here, the water pressure for unlocking the door may be any water pressure. In the case of a fire engine, the pressure may be the pressure of water discharged from the hose of the fire engine, or the pressure of water discharged from the nozzle of a commercially available high pressure washer. The water discharged from the hose of the fire engine may be supplied from a fire hydrant, or may be supplied from a fire prevention water tank.

In the present invention, the type and structure of the locking device may be arbitrary.

As described above, when a door that is locked and unlocked by key operation can also be unlocked by water pressure, the type and structure of the locking device can be arranged on the outer surface of the door, for example. A deadbolt that protrudes from the end face of the door tip side of the door plate when the key is operated, and a dead bolt that protrudes from the end face of the door tip side of the door plate to absorb water pressure. and conversion means for converting the force into a force that causes the door body to sink into the interior of the door.

In this case, if the deadbolt of the locking device protrudes and sinks due to contact with the rotating member that rotates around the central axis of rotation due to the rotation of the key, the conversion means can be converted into a force that rotates the rotation center shaft in a direction in which the deadbolt protruding from the end face of the door on the side of the door tip is retracted into the interior of the door.

As described above, the conversion means converts the water pressure into a force that rotates the rotation center shaft in the direction in which the deadbolt protruding from the edge of the door on the side of the door is retracted into the door. In this case, the type and structure of the conversion means may include, for example, an impeller rotated by water pressure, a first tooth formed at one of both ends in the length direction or in the vicinity thereof, and the other A rack member having a second tooth formed at or near an end, a first pinion coupled to the rotation center shaft of the impeller and meshing with the first tooth, and a rotation center shaft. and a second pinion that meshes with the second tooth portion. In this example, when the impeller is rotated by the water pressure, the rack member is slid, so that the deadbolt protruding from the end surface of the door body on the door tip side of the rotation center shaft is retracted into the door body. direction.

In the present invention, when the conversion means has the type and structure described above, the impeller continues to rotate while receiving water pressure, and the rack member also has a first tooth portion of the rack member. As long as it is in mesh with the first pinion, it will continue to slide. As a result, the second pinion that meshes with the second tooth portion of the rack member also continues to rotate, so that the rotation center shaft of the second pinion rotates more than necessary, causing the rotating member, the dead bolt, etc. to rotate. may be damaged.

Therefore, in the present invention, the rack member is used until the dead bolt protruding from the end surface of the door tip side of the door body is retracted into the door body, and the dead bolt that has been retracted into the door body is retracted into the door body. It is necessary to continue sliding until the body protrudes from the end face on the side of the door.

That is, in the present invention, the permissible sliding amount of the rack member (in other words, the sliding distance) is the distance until the deadbolt protruding from the end surface of the door tip side of the door body sinks into the inside of the door body ( In other words, it is necessary to set the distance until the dead bolt that has been sunk inside the door protrudes from the end face of the door on the door tip side).

Therefore, in the present invention, in order to prevent damage to the rotating member and the deadbolt, it is preferable to provide regulation means for regulating the amount of sliding of the rack member (in other words, rack member sliding amount regulation means).

This restricting means may be of any type and structure as long as it can restrict the amount of sliding of the rack member.

In a first example of the restricting means, a long hole having a length in the length direction of the rack member (in other words, the sliding direction) is formed in the rack member, and the stationary member is fixed to the long hole in the long hole. The shank of a fastener such as a screw is inserted through it.

In this first example, when the rack member slides in one direction and the deadbolt protruding from the edge of the door body on the door tip side sinks into the door body, the length of the long hole in the rack member is reduced. Of the two ends in the length direction, the rack member stops sliding when the shaft portion of the fastening portion is engaged with the peripheral edge portion of the end portion on the side opposite to the sliding direction of the rack member. be. On the other hand, as the rack member slides in the other direction, when the deadbolt that has been sunk inside the door protrudes from the end face of the door on the front end side of the door, The rack member stops sliding when the shaft portion of the fastening portion is engaged with the peripheral edge portion of the end portion of the rack member in the direction opposite to the sliding direction of the rack member.

In a second example of the restricting means, when the rack member slides in one direction and the deadbolt protruding from the end face of the door body on the side of the door tip is retracted into the door body, the rack member is prevented from moving. The rack member slides in the other direction to sink into the door body with the first abutment member with which the end portion of the rack member on the sliding direction side abuts among the both ends in the length direction. When the deadbolt protrudes from the end face of the door body on the door tip side, the second contact member with which the sliding direction end of the rack member abuts among both ends of the rack member in the length direction is immovable. It is arranged on the member.

In the present invention, as described above, the conversion means converts the water pressure into a force that rotates the rotation center shaft in the direction in which the deadbolt protruding from the end face of the door body on the door tip side sinks into the interior of the door body. In the case of conversion, the conversion means can be covered with a cover member having an opening for discharging water at the bottom so that other members and devices in the vicinity of the conversion means do not get wet with water. preferable.

The covering member may be attachable and detachable to the converting means or the immovable member on which the converting means is arranged, or may be unattachable and detachable.

Further, in order to improve the watertightness of the cover member, it is preferable to fill and arrange a sealing material between the cover member and the conversion means or the immovable member on which the conversion means is arranged.

In the present invention described above, it is preferable that the changeover switch is covered with a cover member so that the changeover switch is not covered with dust or wet with water.

In addition, it is preferable that the cover member can be freely attached to and removed from the changeover switch or the non-moving member on which the changeover switch is arranged so that the changeover switch can be operated immediately in an emergency.

Here, the mounting structure of the cover member may be any structure as long as the cover member can be freely mounted and detached.

For example, the mounting structure of the cover member includes an engaging portion provided in the cover member, a changeover switch, or an engaged portion provided in the stationary member on which the changeover switch is arranged, and engaged by the engaging portion. And, it may be configured to include.

In order to improve the watertightness of the cover member, it is preferable to fill and arrange a sealing material between the cover member and the changeover switch or the immovable member on which the changeover switch is arranged.

In the above-described present invention, when the changeover switch is housed inside the housing member as described above, the housing member may be of any type and structure.

The storage member may be a dedicated storage member for storing and arranging the changeover switch (including other components constituting the power switching device) inside, or may not be a dedicated storage member.

In the latter case, the storage member may be, for example, a guide member for guiding the opening/closing movement of the opening/closing body. According to this, the guide member can be a member that also serves as the storage member, and the cost can be reduced accordingly.

When the guide members are arranged on both sides in the width direction of the opening/closing body (in other words, in the left/right direction), the changeover switch is a pair of left and right guide members arranged on both sides in the width direction of the opening/closing body. Of these, it may be housed and arranged inside the guide member on the right side, which is one side, or it may be housed and arranged inside the guide member on the left side, which is the other side.

In the former case, the door may be a right-opening door or a left-opening door. The door body may be a hinged door that can be rotated about a hinge, or a sliding door. However, in the case of a sliding door, a space for a door pocket is required, so the door body is preferably a hinged door.

If the door is a hinged door that opens to the left, when the door is opened to perform power switching work or maintenance work on the power switching device, the operator of the switchgear must be on the left side of the door when the door is opened. There is a risk that the work will have to be done in a cramped space between the door and the building frame such as the wall on the right side. For this reason, considering that there are many right-handed people, it is more preferable that the door body is a hinged door that opens to the right.

Considering the above, if the guide members are arranged on both sides in the width direction of the opening/closing body, the changeover switch should More preferably, it is housed inside the guide member on the right side, and the door body is a hinged door that opens to the right.

The guide member may have any type, structure, or the like. For example, the guide member may include an insertion portion into which the end portion of the opening/closing body in the width direction is slidably inserted, at least a changeover switch and a plug for the second power source. and a storage section in which an outlet into which the power supply is inserted is stored and arranged.

In this example, the insertion section and the storage section may or may not be separated by a partition.

In the former case, even if dust, rainwater, and the like flow in from the insertion portion, they are blocked by the partition and prevented from flowing into the storage portion. That is, according to this, it is possible to protect the changeover switch, the outlet, and the like, which are accommodated and arranged in the accommodating portion, from the outside.

The guide member may be composed of only an insertion portion into which the end portion of the opening/closing body in the width direction is slidably inserted, and at least the changeover switch and the outlet may be accommodated in the insertion portion.

In addition, in the present invention, when an operation device for opening and closing the opening and closing movement and stopping the movement of the opening/closing member is provided, the operation device is housed and arranged inside the housing member in which the selector switch is housed and arranged. You may do so.

Further, in the present invention, the control device for executing drive control of the drive device for driving the opening/closing member is housed and arranged together with the operating device inside the housing member in which the selector switch is housed and arranged. good too. In this case, the control device, operation device and switch may be unitized. This facilitates maintenance of the control device, the operation device, and the changeover switch, which are closely related to each other. Further, according to this, the wiring work of the control device can be facilitated and the number of wiring and piping members can be reduced.

In the present invention as described above, the type, structure, etc. of the changeover switch may be of any type as long as it is capable of switching between the first power source and the second power source. It may or may not have a part.

Examples of the changeover switch in the former case include a knife switch, a toggle switch (with an operating portion that moves up and down), a rocker switch, etc. Examples of the changeover switch in the latter case include a rotary switch, a selector A switch, a toggle switch (with an operating portion that moves in the horizontal direction), a push button switch, and the like can be mentioned.

In the present invention, as described above, in the case where the operation portion of the switch is rotatable in the vertical direction, by rotating the operation portion to the upper rotation limit position, the first power source power is supplied from the second power supply, and by rotating the operation unit to the lower rotation limit position, the type and structure of the changeover switch is, for example, an opening The operation part protrudes from a groove formed in the circumferential direction of the outer peripheral surface of the semicircular part and is guided by the groove. It may or may not be vertically rotatable.

In the present invention, when the storage member for storing and arranging the changeover switch is used as a guide member for guiding the opening/closing movement of the opening/closing member, as described above, the changeover switch has the same cross-sectional shape in the longitudinal direction. It may or may not be housed inside the guide member either directly via a pedestal member having a hat-shaped cross section which is continuous in the direction, or further via a mounting member.

In the former case, the type and structure of the pedestal member may be arbitrary. It consists of left and right first bent portions that are bent 90 degrees to the side opposite to the side, and left and right second bent portions that are bent 90 degrees outward in the width direction from the tip of each of the first bent portions. It is.

In this example, a space is formed under the flat portion (in other words, the upper surface portion or the horizontal portion) of the base member by the flat portion and the left and right first curved portions (in other words, hanging portions). Therefore, this space can be used as a wiring space for components of the power switching device including the changeover switch (in other words, a space for arranging power lines and the like).

The outlet into which the power plug of the second power supply is inserted may or may not be arranged on the flat portion of the base member and integrated with the changeover switch.

In the former case, the changeover switch and outlet can be assembled in advance at the factory in an integrated form, and at the site where the switchgear is installed, the changeover switch and the outlet integrated at the factory can be installed. All you have to do is place the outlets.

That is, as a result, the operation of storing and arranging the changeover switch and the outlet inside the guide member and the operation of removing them from the inside of the guide member are easier than in the case where they are not integrated.

Here, integrating the changeover switch and the outlet means, for example, placing and fixing the changeover switch and the outlet (in other words, mounting) on the upper surface of the base member.

The longitudinal direction of the pedestal member when housed and arranged inside the guide member may be the vertical direction or the horizontal direction.

In the latter case, compared to the former case, it is necessary to increase the dimension of the guide member in the width direction (in other words, the direction orthogonal to the opening/closing movement direction of the opening/closing member), which is the horizontal direction of the guide member. It is preferable that the longitudinal direction of the pedestal member when housed and arranged inside the is the vertical direction.

If the longitudinal direction of the pedestal member when housed and arranged inside the guide member is the vertical direction, the changeover switch and the outlet may be arranged vertically in the order of the changeover switch and the outlet from the top. You may arrange vertically in order of an outlet and a changeover switch.

Here, if the second power source is movable from the vehicle and is movable on the floor or the like, in an emergency, a power line extending from the second power source (in other words, , electric cord) is inserted into an outlet.

Therefore, when the changeover switch and the outlet are arranged vertically from the top, the length of the power supply line extending from the second power supply is shorter than when the outlet is arranged vertically and the changeover switch is arranged in the order from the top. can do.

Components of the power supply switching device other than the changeover switch and the outlet may or may not be arranged on the flat portion of the base member to be integrated with the changeover switch and the outlet.

In addition, it is preferable to arrange the changeover switch at a height position that is easy for the person who performs the switching operation of the power source to operate. For example, the changeover switch is preferably arranged at a height of about 130 cm from the floor or ground.

In the present invention, when a plurality of switchgears are installed at the site, a selector switch may or may not be provided for each switchgear.

According to the latter case, only one changeover switch is required to be installed, and the operation of this one changeover switch makes it possible to switch the power supply of all the switchgears.

In the present invention, the generator and the storage battery, which are the second power supply mounted on the vehicle, are of various manufacturers and of various types even by the same manufacturer. The shape of the power plug does not necessarily match the shape of the outlet of the power switching device.

For this reason, a converter for adapting the shape of the power plug to the shape of the outlet of the power switching device so that various power plugs of power lines extending from various second power sources can be inserted into the outlet of the power switching device. It is preferable to manufacture the adapter in advance and always keep the manufactured conversion adapter on site.

INDUSTRIAL APPLICABILITY The present invention can be applied to various opening/closing devices such as a shutter device in which a shutter curtain serves as an opening/closing member, an overhead door device in which a sliding door serves as an opening/closing member, a smokeproof hanging wall device, and a sliding door device.
