Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, in areas where volcanic ash may fall, a filter for capturing floating substances such as volcanic ash is installed in an intake mechanism attached to a generator or the like. This filter requires regular cleaning. For this reason, man-hours for removing the filter from the intake mechanism are generated during cleaning. As a countermeasure, by providing a mechanism for directly hitting the filter in the state where it is attached to the intake mechanism, floating substances captured by the filter may be detached from the filter.

[0005] However, with such a configuration, since the filter is directly hit, it is conceivable that the filter may be damaged.

[0006] An object of the present disclosure is to suppress damage to the filter as compared with the case of providing a mechanism for directly hitting the filter in a configuration for cleaning the filter without removing it from the intake mechanism.

Means for Solving the Problems

[0007] The intake mechanism according to the first embodiment is characterized by comprising: an intake duct having an intake passage through which air from the outside passes; a filter attached to the intake duct for capturing airborne particles contained in the air passing through the intake passage; and a vibrator attached to the intake duct for vibrating the intake duct to release airborne particles captured by the filter from the filter.

[0008] According to the above embodiment, the filter that captures airborne particles is attached to the intake duct. The vibrator vibrates the intake duct to dislodge the airborne particles captured by the filter. As the airborne particles are dislodged from the filter, the filter is cleaned. In this configuration, where the filter is cleaned without removing it from the intake mechanism, damage to the filter can be suppressed compared to a system that directly strikes the filter.

[0009] The intake mechanism according to the second embodiment is characterized in that, in the intake mechanism described in the first embodiment, the intake port of the intake passage of the intake duct faces downward, and the filter is attached to the intake port.

[0010] According to the above embodiment, the filter is attached to an intake port facing downwards. This allows airborne particles that have detached from the filter to fall outside the intake duct.

[0011] The operating system according to the third embodiment is characterized by comprising: an intake mechanism according to claim 1 or 2; a device operated by air drawn in from the intake mechanism; and a suppression member that connects the intake duct of the intake mechanism to the device and suppresses the transmission of vibrations of the intake duct to the device.

[0012] According to the above embodiment, the suppression member suppresses the transmission of vibrations from the intake duct to the device. This prevents damage to the device. [Effects of the Invention]

[0013] According to this disclosure, in a configuration for cleaning the filter without removing it from the intake mechanism, damage to the filter can be suppressed compared to a configuration in which a mechanism is provided to directly strike the filter. [Brief explanation of the drawing]

[Figure 4] This is a perspective view showing an intake mechanism according to a second embodiment of the present disclosure. [Figure 5] This is a front view showing an intake mechanism according to a second embodiment of the present disclosure. [Modes for carrying out the invention]

[0015] <First Embodiment> An example of a power generation system and intake mechanism according to the first embodiment of this disclosure will be described with reference to Figures 1 to 3. The arrow H shown in each figure indicates the vertical direction of the intake mechanism, the arrow W shown in each figure indicates the width direction of the intake mechanism, which is perpendicular to arrow H and is horizontal, and the arrow D shown in each figure indicates the depth direction of the intake mechanism, which is perpendicular to arrows H and W and is horizontal.

[0016] (Intake mechanism 10) As shown in Figure 1, the intake mechanism 10 is attached to the air intake port 100a of the generator 100, which is located outdoors. This intake port 100a opens on one side (left side in the figure) in the width direction of the generator 100.

[0017] This intake mechanism 10 includes an intake duct 12, a filter 22, a vibration machine 32, and a control unit 50. The generator 100 is an example of a device, and the flexible duct 42 is an example of a suppression member.

[0018] Note that a power generation system 90 that generates electricity including the generator 100, the intake mechanism 10, and the flexible duct 42 is configured. The power generation system 90 is an example of an operating system.

[0019] 〔Flexible duct 42〕 As shown in FIG. 1, the flexible duct 42 is attached to the suction port 100a of the generator 100. Specifically, the flexible duct 42 is formed of a metal material or a resin material, has a bellows shape, and is formed in a rectangular tube shape. One end of this flexible duct 42 is attached to the suction port 100a. And the flexible duct 42 is arranged so as to extend in the width direction.

[0020] In this configuration, when the other end of the flexible duct 42 vibrates, the flexible duct 42 is configured to suppress the transmission of the vibration of the other end to the generator 100 by deforming.

[0021] 〔Intake duct 12〕 As shown in FIGS. 1 and 2, the intake duct 12 is attached to the other end of the flexible duct 42 and has a box shape with an open bottom.

[0022] Specifically, the intake duct 12 is formed in a rectangular parallelepiped shape made of a metal material or a resin material, and includes a side plate 12b facing one side in the width direction, a side plate 12c facing the back side in the depth direction, a side plate 12d facing the front side in the depth direction, and a top plate 12e. And an intake flow path 14 is formed inside the intake duct 12, and the intake port 14a of the intake flow path 14 is opened downward.

[0023] In this configuration, the air drawn in from the intake port 14a into the intake duct 12 flows through the intake passage 14 and the flexible duct 42 formed inside the intake duct 12 and is supplied to the generator 100 from the intake port 100a.

[0024] [Vibrator 32] The vibrator 32 is a device that applies vibration to the intake duct 12, and as shown in Figures 1 and 2, it is attached to the top plate 12e of the intake duct 12. As a result, when the vibrator 32 is in operation, the intake duct 12 vibrates.

[0025] Furthermore, even if the intake duct 12 vibrates, the flexible duct 42 deforms, which suppresses the transmission of vibrations from the intake duct 12 to the generator 100.

[0026] [Filter 22] The filter 22 is a so-called volcanic ash filter and is attached to the intake duct 12 as shown in Figures 1 and 2. Specifically, it is attached to the intake port 14a of the intake passage 14 in the intake duct 12. In other words, the filter 22 is attached to the inlet of the intake passage 14 in the intake duct 12. In this embodiment, the filter 22 is designed to capture volcanic ash and the like contained in the air passing through the intake port 14a of the intake passage 14 and separate the volcanic ash from the air passing through the filter 22. Volcanic ash is an example of suspended matter contained in the air.

[0027] [Control Unit 50] -Hardware configuration of the control unit 50- As shown in Figure 3(A), the control unit 50 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 52, a RAM (Random Access Memory) 53, storage 54, and a communication interface (I / F) 55. Each component is connected to the others via a bus 56 for communication. The CPU 51 is an example of a processor.

[0028] The CPU 51 is a central processing unit that executes various programs and controls various components. Specifically, the CPU 51 reads programs from the ROM 52 or storage 54 and executes them using the RAM 53 as a workspace. The CPU 51 controls each component and performs various calculations according to the programs stored in the ROM 52 or storage 54.

[0029] In this embodiment, for example, the ROM 52 or storage 54 stores an operating program for operating the vibrator 32 based on gas information from a volcanic gas meter 110 installed outdoors.

[0030] RAM 53 temporarily stores programs or data as a working area. Storage 54 consists of an HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs, including the operating system, and various data.

[0031] The communication interface 55 is an interface for communicating with the volcanic gas meter 110, the vibrator 32, etc., and standards such as Ethernet®, FDDI, and Wi-Fi® are used.

[0032] When executing the above operating program, the control unit 50 uses the above hardware resources to implement various functions. Next, the functional configuration of the control unit 50 that implements these various functions will be described.

[0033] -Functional configuration of the control unit 50- As shown in Figure 3(B), the control unit 50 includes a receiving unit 50a, a determination unit 50b, and an operating unit 50c. Each functional configuration is realized by the CPU 51 reading and executing an operating program stored in the ROM 52 or storage 54. The details of the control unit 50 will be explained later along with its operation.

[0034] 〔others〕 Next, the support mechanism 120 that supports the intake mechanism 10 will be described. As shown in Figure 1, the support mechanism 120 comprises a gate-shaped frame 122 and a wire 124 that hangs down from the gate-shaped frame 122 and whose lower end is attached to the intake duct 12.

[0035] The gantry frame 122 is positioned to surround the intake duct 12. A pair of wires 124 are provided, extending downward from the horizontal bar 122a of the gantry frame 122. The lower end of one wire 124 is attached to the side plate 12c of the intake duct 12, and the lower end of the other wire 124 is attached to the side plate 12d of the intake duct 12. In this way, the support mechanism 120 supports the intake duct 12 of the intake mechanism 10.

[0036] (action) Next, the operation of the intake mechanism 10 will be explained. The operation of the intake mechanism 10 is carried out by the control unit 50 controlling each part. Furthermore, in the initial state of the intake mechanism 10 and the generator 100, the vibrator 32 and the generator 100 are inactive.

[0037] In this state, when the generator 100 is operated, the generator 100 draws in air through the intake port 100a shown in Figure 1 and the intake mechanism 10. In other words, the generator 100 operates using the air drawn in from the intake mechanism 10. Specifically, the air drawn in from the filter 22 attached to the intake duct 12 flows through the intake passage 14 of the intake duct 12 and the flexible duct 42, and is supplied to the generator 100 from the intake port 100a.

[0038] Furthermore, when the generator 100 is operated, the receiving unit 50a of the control unit 50 shown in Figure 3(B) receives measurement data from the volcanic gas meter 110 at predetermined intervals. In addition, the determination unit 50b determines whether the measurement data received by the receiving unit 50a is above a predetermined standard value. If the measurement data is determined to be below the standard value, the operating unit 50c maintains the non-operating state of the vibrator 32.

[0039] On the other hand, if the measurement data is determined to be above the standard value, the operating unit 50c activates the non-operating vibrator 32. When the vibrator 32 is activated, the intake duct 12 shown in Figure 2 vibrates. Also, if the measurement data is above the standard value, volcanic ash will be included in the air drawn into the intake mechanism 10.

[0040] However, the filter 22 captures volcanic ash contained in the air passing through it and separates the volcanic ash from the air passing through the filter 22. The air separated from the volcanic ash then flows through the intake passage 14 of the intake duct 12 and the flexible duct 42 and is supplied to the generator 100 from the intake port 100a.

[0041] Here, the volcanic ash captured by the filter 22 is shaken off the filter 22 and detached from it due to the vibration of the intake duct 12 to which the filter 22 is attached. The detached volcanic ash then falls downward and does not enter the intake passage 14 of the intake duct 12.

[0042] Here, even when the vibrator 32 is operating, the receiving unit 50a receives measurement data at predetermined intervals. If the measurement data is determined to be below a reference value, the operating unit 50c deactivates the operating vibrator 32.

[0043] (summary) As explained above, in the intake mechanism 10, the intake duct 12 to which the filter 22 is attached vibrates, causing the volcanic ash captured by the filter 22 to be shaken off and detached from the filter 22. The detachment of the volcanic ash from the filter 22 cleans the filter 22. In this configuration, in which the filter is cleaned without removing it from the intake mechanism, damage to the filter 22 can be suppressed compared to a case where a mechanism that directly strikes the filter is provided.

[0044] Furthermore, in the intake mechanism 10, the filter 22 is attached to the intake port 14a facing downwards. This allows volcanic ash that has detached from the filter 22 to fall to the outside of the intake duct 12.

[0045] Furthermore, in the power generation system 90, the flexible duct 42 suppresses the transmission of vibrations from the intake duct 12 to the generator 100. This helps to prevent damage to the generator 100.

[0046] <Second Embodiment> An example of an intake mechanism according to the second embodiment of this disclosure will be described with reference to Figures 4 and 5. The second embodiment will primarily describe the differences from the first embodiment.

[0047] As shown in Figure 4, the intake mechanism 60 according to the second embodiment is formed in the outer wall 202 of the structure 200 and is attached to an intake port 202a that takes in air into the interior of the structure 200. This intake port 202a opens on one side in the width direction.

[0048] As shown in Figures 4 and 5, the intake mechanism 60 comprises an intake duct 12, a filter 22, a vibrator 32, and a control unit 50. A mounting rubber 72 connects the intake duct 12 and the intake port 202a of the intake mechanism 60. The mounting rubber 72 is an example of a restraining member.

[0049] The mounting rubber 72 is attached to the intake port 202a of the structure 200. Specifically, the mounting rubber 72 is made of rubber material and has a rectangular annular shape. One end of the mounting rubber 72 is attached to the intake port 202a. The other end of the mounting rubber 72 is attached to the intake duct 12.

[0050] The support mechanism 220 supporting the intake mechanism 60 includes a pair of wires 224, as shown in Figures 4 and 5. The pair of wires 124 extend from the upper portion of the outer wall 202 of the structure 200 relative to the intake port 202a toward the upper end of the side plate 12b of the intake duct 12. The lower end of one wire 224 is attached to one corner of the upper end of the side plate 12b, and the lower end of the other wire 124 is attached to the other corner of the upper end of the side plate 12b. In this way, the support mechanism 220 supports the intake duct 12 of the intake mechanism 60.

[0051] In this configuration, the mounting rubber 72 suppresses the transmission of vibrations from the intake duct 12 to the structure 200. This prevents damage to the structure 200. The operation of other aspects of the second embodiment is the same as that of the first embodiment.

[0052] Although this disclosure has described specific embodiments in detail, it will be apparent to those skilled in the art that this disclosure is not limited to these embodiments, and that various other embodiments are possible within the scope of this disclosure. For example, in the above embodiment, the filter 22 captured volcanic ash, but it is sufficient for the filter to capture suspended matter contained in the air, and the filter may capture dust, dirt, etc. contained in the air. Thus, the filter 22 does not have to be a volcanic ash filter, and it is sufficient for the filter 22 to capture dust, dirt, etc. contained in the air.

[0053] Furthermore, in the above embodiment, the control unit 50 activated or deactivated the vibrator 32 based on the measurement results of the volcanic gas meter 110. However, a wind speed detection sensor may be placed inside the intake duct 12 to continuously measure the wind speed inside the intake duct 12. If the measured wind speed is above a predetermined reference value, the vibrator 32 may be activated, and if the measured wind speed is below the reference value, the vibrator 32 may be deactivated.

[0054] Furthermore, in the above embodiment, the control unit 50 activated or deactivated the vibrator 32 based on the measurement results of the volcanic gas meter 110. However, a differential pressure flow meter is also provided to measure the slight differential pressure before and after the filter, and the differential pressure before and after the filter is continuously measured. If the measured differential pressure is above a predetermined reference value, the vibrator 32 is activated, and if the measured differential pressure is below the reference value, the vibrator 32 is deactivated.

[0055] Furthermore, in the above embodiment, the filter 22 was attached to the intake port 14a facing downwards, but for example, the intake port may be facing horizontally, and the filter may be attached to this horizontally facing intake port.

[0056] Furthermore, in the first embodiment described above, the control unit 50 activated or deactivated the vibrator 32 based on the measurement results of the volcanic gas meter 110. However, the vibrator 32 may be activated in response to an activation signal from the intake fan provided on the generator 100, and deactivated in response to a deactivation signal from the intake fan.

[0057] Furthermore, in the second embodiment described above, the control unit 50 activated or deactivated the vibrator 32 based on the measurement results of the volcanic gas meter 110. However, the vibrator 32 may also be activated in response to an activation signal from an intake fan installed on the structure 200, and deactivated in response to a deactivation signal from the intake fan.

[0058] Furthermore, although not specifically described in the above embodiment, the frequency of the vibrator 32 may be periodically changed while the vibrator 32 is in operation.

[0059] Furthermore, although not specifically described in the above embodiment, the amplitude of the vibrator 32 may be periodically changed while the vibrator 32 is in operation.

[0060] Furthermore, although not specifically described in the above embodiment, the excitation direction by the vibrator 32 may be periodically changed while the vibrator 32 is in operation. [Explanation of Symbols]
