Description

[Technical Field]

[0001] The present invention relates to an installation structure for an emergency power supply device in a multi-story parking system. [Background technology]

[0002] Multi-story parking systems that allow pallets supporting vehicles to be raised and lowered are widely used. For example, the multi-story parking system disclosed in Patent Document 1 is configured with a lifting floor that allows the pallets supporting vehicles to be raised and lowered within a building, and a lateral movement device that slides the pallets supported by the lifting floor in the lateral direction.

[0003] When a vehicle is brought into the warehouse, it enters through an entrance on the ground floor of the building and is parked on a pallet on the ground floor. The vehicle, supported by the pallet on the ground floor, is raised by a lifting floor and slid by a lateral movement device to be sent to a designated storage area for storage.

[0004] The building's ground floor is also equipped with a turning device (turntable) that changes the orientation of the pallets. When a vehicle is to be removed from the depot, the pallet and vehicle are slid from the designated storage area onto a lifting floor, which then lowers them to the ground floor. The pallet supporting the vehicle is rotated 180 degrees by the turning device, allowing the vehicle to be removed from the entrance facing forward.

[0005] In recent years, emergency power supply devices that supply power in place of the commercial power supply when the power supply from the electric power company (hereinafter referred to as the commercial power supply) is cut off during a disaster, etc., are being installed in various facilities. For example, Patent Document 2 discloses an emergency power supply device that includes a storage battery, a charge / discharge controller, a circuit switching unit that switches between the commercial power supply and the storage battery, a power output terminal, an external power generation source (a solar power generation system), etc. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-270351 [Patent Document 2] Utility Model Registration No. 3171974 Summary of the Invention [Problem to be solved by the invention]

[0007] Because multi-story parking systems require electricity for vehicles to enter and exit the system, it is important to have an emergency power supply that can be used in the event of a commercial power outage. It is also important for residential and business locations near the multi-story parking system to have emergency power supplies in case of a power outage. If the multi-story parking system is equipped with an emergency power supply, it can also supply power to nearby areas in the event of a disaster.

[0008] However, because emergency power supply systems involve large equipment, it is often difficult to secure the installation space. In particular, in the case of multi-story parking systems, since a large number of vehicles are stored within the building, securing the installation space for the emergency power supply system can pose a problem, requiring the building to be larger. In addition, the increase in building size leads to increased costs, and there are legal restrictions on the building's area and height, so it may not be possible to accommodate such an increase in size.

[0009] Therefore, the present invention aims to install an emergency power supply device in a multi-story parking system while minimizing the increase in size of the building as much as possible. [Means for solving the problem]

[0010] In order to solve the above problems, the present invention provides an emergency power supply device installation structure (Configuration 1) that is installed in a multi-story parking system that includes a pallet that supports a vehicle and a lifting floor that raises and lowers the pallet, and that includes a storage battery, a control unit that controls the charging and discharging of the storage battery, an output terminal unit for supplying power to the outside, and an external power generating source that supplies power to the storage battery, and that at least one device selected from the storage battery, the control unit, and the external power generating source is disposed in a pit that is provided directly below the lifting floor, which is located at the lowest position in the lifting range of the lifting floor.

[0011] In the configuration 1, the device disposed in the pit may include the storage battery (configuration 2).

[0012] In the configuration 1 or 2, the device placed in the pit can be configured to float on the surface of the accumulated water in the pit (configuration 3).

[0013] In configuration 3, the device can be configured such that its movement is guided between a state in which it is placed on the bottom of the pit and a state in which it is floating on the water surface by a guide member arranged in the pit (configuration 4). [Effects of the Invention]

[0014] According to this invention, it becomes possible to install an emergency power supply device in a multi-story parking system while minimizing the increase in size of the building. [Brief explanation of the drawings]

[0015] [Figure 1] FIG. 1 is a front view of a multi-story parking system equipped with an emergency power supply device according to an embodiment of the present invention; [Figure 2] Enlarged side view of the main part of Figure 1 [Figure 3] Enlarged front view of the main part of Figure 1 [Figure 4] Plan view of the pit area [Figure 5] VV cross section of Figure 4 [Figure 6] Emergency power supply configuration diagram [Figure 7] A plan view showing a modified example of the case [Figure 8] Front view of Figure 6 DETAILED DESCRIPTION OF THE INVENTION

[0016] An embodiment of the present invention will be described with reference to the drawings. As shown in Figure 1, a multi-story parking system (multi-story parking lot) 1 of this embodiment is configured to include a lifting device 70 equipped with a hoist (winch drum) 71 that raises and lowers a lifting floor (carrier) 3' that enables a pallet P supporting a vehicle A to be raised and lowered within a building 4, and a lateral movement device (lateral travel device) 80 that slides the pallet P supported by the lifting floor 3' in the lateral direction.

[0017] An entrance / exit 4a is provided on the ground floor of the building 4. The entrance / exit 4a faces a transfer space (standing parking space) 2, which is a space for vertical movement of the lift floor 3', and adjacent to both sides of the transfer space 2, there are storage areas (parking spaces) 5 equipped with multiple parking floors (parking space stoppers) 3.

[0018] The lifting device 70 is equipped with a wire 72 connected to a lifting floor 3' located in a loading / unloading passage (berth) F inside the building 4 facing the entrance / exit 4a, and a hoist 71 is disposed at the top of the building 4 to wind up the wire 72. When the hoist 71 winds up the wire 72, the lifting floor 3' and a pallet P placed on the lifting floor 3' rise, and when the wire 72 is unwound, the lifting floor 3' and the pallet P descend. By operating the hoist 71 with a vehicle A parked on the pallet P, the vehicle A can be moved between the height facing the loading / unloading passage F and the height of the specified parking floor 3. The hoist 71 is disposed in a machine room disposed at the top of the building 4.

[0019] The lateral movement device 80 is a device that slides the pallet P laterally between the lifting floor 3' and the parking floor 3 that is located to the side (at the same height) of the lifting floor 3'. By operating the lateral movement device 80 while the vehicle A is parked on the pallet P, the vehicle A can be moved between the lifting floor 3' and the parking floor 3.

[0020] Similar to Patent Document 1, the lateral movement device 80 of the embodiment has protruding ribs (not shown) that protrude downward from two opposing sides of the rectangular pallet P in a plan view, supported by a number of rollers (not shown), thereby allowing the pallet P to slide laterally, but other well-known structures may also be adopted for the structure of the lateral movement device 80. Furthermore, the hoist 71 is not limited to that of the embodiment, and other well-known structures may also be adopted.

[0021] When vehicle A is to be stored, it is allowed to enter through entrance / exit 4a and parked on a pallet P on a lifting floor 3' in the entrance / exit passage F. Vehicle A supported on pallet P is lifted by hoist 71 and slid by lateral movement device 80, and sent to the designated parking floor 3 for storage.

[0022] Furthermore, the loading / unloading route F of the building 4 is equipped with a turning device (turntable) 20 that changes the direction of the pallets P. The turning device 20 is disposed in a pit 10 that is excavated directly below the transfer space 2. As shown in FIGS. 2 and 4, the pit 10 is located directly below the lifting floor 3' that is located at the lowest position in the lifting range of the lifting device 70, and is rectangular in shape when viewed from above, and is provided at a predetermined depth from the surface of the ground G.

[0023] The turning device 20 is configured to include a base 21 placed on the bottom of the pit 10, and a rod (turntable turning device) 22 that protrudes upward from the base 21 and whose protrusion amount is variable. The turning device 20 including the rod 22 can rotate 360 ​​degrees around a vertical axis. When the rod 22 extends and pushes up the pallet P on the loading / unloading path F, the pallet P moves upward and away from the lifting floor 3'. In this state, the turning device 20 operates to change the direction (turn) of the pallet P.

[0024] When vehicle A is to be taken out, the pallet and vehicle are slid from a designated storage area onto the lifting floor 3' and then lowered to the ground floor using the lifting floor 3'. The pallet P supporting vehicle A is rotated 180 degrees by a rotating device, allowing vehicle A to be taken out facing forward through the entrance 4a.

[0025] The emergency power supply device provided in this multi-story parking system 1 will now be described.

[0026] The emergency power supply device is configured to include a storage battery device 30, a control unit 40 that controls the charging and discharging of the storage battery device 30, an output terminal unit 50 for supplying power to the outside, and an external power generating source 90 that supplies power to the storage battery device 30.

[0027] The storage battery device 30 is composed of a well-known secondary battery. A control unit 40 controls charging of the storage battery device 30 and discharging (power supply) from the storage battery device 30 to the outside. As shown in FIG. 6 , the control unit 40 includes a charge controller 41 that controls charging to the storage battery device 30 and discharging from the storage battery device 30, a DC / AC inverter 42 that adjusts the power supplied to the output terminal unit 50, and the like. The configuration of the control unit 40 is not limited to this embodiment, and various configurations can be adopted depending on the specifications.

[0028] As shown in Figures 2, 3, and 6, the external power generation source 90 is made up of a wind power generation device 91 and a solar power generation device 92. The wind power generation device 91 uses wind power to rotate a windmill, and the rotational energy of the wind power to rotate a generator to obtain power (electrical energy). The solar power generation device 92 converts sunlight into electricity using a solar cell module equipped with a solar panel. These power generation devices are also controlled by the control unit 40. Note that the external power generation source 90 may include both the wind power generation device 91 and the solar power generation device 92, as in this embodiment, or may be configured to include only one of them. Furthermore, instead of or in addition to them, the external power generation source 90 may be configured to include a generator equipped with an internal combustion engine, such as a diesel generator.

[0029] In this embodiment, the control panel 6 of the multi-story parking device 1 is disposed to the side of the entrance / exit 4a of the building 4. This position is immediately below the wind power generation device 91 and the solar power generation device 92. The output terminal unit 50 is also disposed next to the side of the control panel 6 (see FIG. 3). The control panel 6 and the output terminal unit 50 are attached to the wall of the building 4, so they are disposed without occupying a large space. Note that the reference numeral 93 in the figure denotes a fire extinguishing equipment room (cylinder room) that houses fire extinguishing devices such as fire cylinders.

[0030] The storage battery device 30 and the control unit 40 are placed in the pit 10. The storage battery device 30 is composed of a battery unit (battery body) 31 equipped with cells that generate electromotive force, etc. By placing the storage battery device 30 and the control unit 40 in the pit 10, the available space in the multi-story parking device 1 can be effectively utilized. This is because the pit 10 is formed by digging into the ground G in order to place the turning device 20, and as shown in Figures 2 and 4, there is space (empty space) around the turning device 20.

[0031] In this embodiment, both the storage battery equipment 30 and the control unit 40 are selected as devices to be placed in the pit 10, but in addition, an external power generation source 90 may also be placed in the pit 10. Although it is not realistic to place the wind turbine of the wind power generation equipment 91 or the solar panels of the solar power generation equipment 92 in the pit 10, it is possible to place their auxiliary equipment in the pit 10. Furthermore, if a generator equipped with an internal combustion engine is used as the external power generation source 90, it can be placed in the pit 10. There is also the option of placing only the storage battery equipment 30, only the control unit 40, or only the external power generation source 90 in the pit 10. In other words, at least one device selected from the storage battery equipment 30, the control unit 40, and the external power generation source 90 can be placed in the pit 10.

[0032] The pit 10 is provided with drainage equipment (not shown), such as a pump, to prevent rainwater and the like from accumulating within the pit 10. However, if an unexpected amount of rainfall occurs, it is possible that the drainage within the pit 10 will not be able to keep up, resulting in temporary accumulation of stagnant water W within the pit 10. To deal with such an event, the devices (in this embodiment, the storage battery device 30 and the control unit 40) placed within the pit 10 are designed to float on the surface of the stagnant water W by buoyancy. This prevents the devices (particularly electronic devices) that make up the emergency power supply from being submerged (see FIG. 5).

[0033] In the embodiment shown in Figures 4 and 5, the device is housed in a watertight case (panel) C, and the buoyancy of the gas filled inside the case C causes the entire device to float on the water surface (without touching the water). However, other configurations are also possible, such as using a material for the case C that has a lower specific gravity than water, allowing the device to float on the water surface, or having a concave shape with an upward opening (like a boat floating on the water surface), allowing the device to float on the water surface. The case C in the embodiment is a rectangular parallelepiped that is square in plan view, but its shape can be various. Furthermore, if the device is housed in a watertight case C, it is also possible for the device not to float on the water surface.

[0034] In addition, in the embodiment, the movement of the case C floating on the water surface is guided by a guide member 61 arranged in the pit 10. That is, as shown in Figs. 4 and 5, the movement of the case C is guided by the guide member 61 between a state in which it is placed on the bottom of the pit 10 and a state in which it is floating on the water surface. This prevents the case C from moving beyond an expected range. It also prevents the case C from tipping over in the pit 10 (becoming upside down).

[0035] In the embodiment, the guide members 61 are L-shaped steel beams with an L-shaped cross section, which are arranged at the four corners of the rectangular case C in a plan view, but the shape, number, and location of the guide members 61 can be freely set. Also, for example, the guide members 61 may be configured with a guide body 61a extending in the vertical direction and a stopper portion 61b protruding laterally from the guide body 61a (see FIG. 5). When the case C abuts against the stopper portion 61b, further floating of the case C is restricted. Therefore, such a configuration of the guide members 61 can be adopted, for example, when there is an upper limit to the water level of the accumulated water W.

[0036] Although the cables connecting the storage battery equipment 30, the control unit 40, and the external power generation source 90 are not shown in the figures, these cables can be freely routed within the pit 10 and the building 4. However, it is desirable that the cables within the pit 10 have a watertight structure.

[0037] 7 and 8 show a modified example of this embodiment. In this modified example, a float member 64 is attached to the outside of a watertight case C. The case C floats on the surface of the accumulated water W due to the buoyancy of the float member 64, which has the advantage of increasing the freedom to select the material and shape of the case C. For example, even if the case C itself cannot float on water, by attaching a float member 64, it can easily be made into a device that floats on water.

[0038] In this embodiment, a bullet-shaped float 64a with small diameters at both axial ends and a large diameter in the axial center is used as the float member 64, and a cable 64b is inserted through an axial hole formed along the axis of the float 64a. A material with a specific gravity lower than that of water, such as polystyrene foam, can be used as the material for the float 64a. A plurality of such floats 64a are arranged in parallel along the four side surfaces c of the case C, thereby generating stable buoyancy for the case.

[0039] 7 and 8, the guide member 61 is axially shaped and is inserted into a through-hole 62 in the vertical direction provided in the case C. The through-hole 62 passes through between the upper surface a and the lower surface b of the case. The guide member 61 can also be configured in this manner.

[0040] In the above embodiment, the configuration of the present invention was explained using as an example a multi-story parking system 1 equipped with a turning device 20 within a pit 10, but the present invention can also be applied to a multi-story parking system 1 that does not have a turning device 20, as long as it has a pit 10.
