Flying body mounting unit and flying body

Abstract

To solve the problem that a flying body such as a multicopter (drone) can mount a fire sensor to enable attachment / detachment of a fire sensor body at a higher place, but a torque of rotating force of the flying body to fly by rotating is small so that it is difficult to allow the fire sensor body to rotate and to be attached / detached to / from a sensor base.SOLUTION: A flying body mounting unit to be attachable to a flying body includes a sucker part, a suction mechanism, and a fire sensor holding / rotating mechanism. The suction mechanism sucks an inner side of the sucker part so as to be fixed to a periphery of a fire sensor by sucking. In this state, the holding / rotating mechanism allows the fire sensor to rotate to be attached / detached to / from a sensor base.SELECTED DRAWING: Figure 4

Description

[Technical field]

[0001] The present invention relates to a unit to be mounted on an aircraft and to an aircraft that is suitable for attaching and detaching a fire detector to be installed at a high place. [Background technology]

[0002] Fire detectors such as smoke detectors and flame detectors are installed on ceilings etc. to detect smoke and flames, and thus fires. Such fire detectors are installed by attaching the fire detector body to a detector base installed on the ceiling etc. Then, when inspecting or replacing the fire detector, the fire detector body can be removed from the detector base and reattached.

[0003] In the inventions of Patent Documents 1 and 2, a pair of blade receiving metal fittings is provided on the detector base, and a pair of blade fittings is provided on the detector body. The detector body is then fitted into the detector base and rotated so that the blade fittings enter the blade receiving metal fittings, thereby mechanically and electrically fixing the detector body to the detector base. The detector body can be removed from the detector base by rotating it in the opposite direction. The fire detector body attached to the detector base can be removed as well as electrically disconnected by rotating it by hand or with a remover. The fire detector body can be attached to the detector base by holding the fire detector body by hand or with a remover, pressing it against the detector base, and rotating it in the opposite direction to when it was removed, thereby fitting the blade fittings into the blade receiving metal fittings.

[0004] [Patent Document 1] JP 2016-021199 A [Patent Document 2] JP 2019-169075 A Summary of the Invention [Problem to be solved by the invention]

[0005] It is necessary to monitor fires in large spaces such as atriums and dome stadiums. In order to monitor fires in large spaces, a fire detector such as a flame detector can be installed on the ceiling to widen the monitoring area. However, if a fire detector is installed on the ceiling of a large space, scaffolding must be constructed when testing or replacing the fire detector, and the cost of testing or replacing the fire detector is high. Therefore, it is possible to mount a detachable unit on an aircraft such as a multicopter (drone) to remove or attach the fire detector body at a high place. However, the rotational flight of the aircraft does not provide enough torque to provide the rotational force to attach or detach the fire detector, so it is difficult to rotate the fire detector body to attach it to or remove it from the detector base. [Means for solving the problem]

[0006] One embodiment of the present invention is an aircraft-mounted unit that can be attached to an aircraft, and includes a suction cup, a suction mechanism, and a mechanism for holding and rotating a fire detector main body, and in a state in which the inside of the suction cup is sucked by the suction mechanism and adhered to and fixed around a detector base, the fire detector main body can be rotated by the holding and rotating mechanism to be attached to or removed from the detector base. The periphery of the detector base that is adhered to may be the flange of the detector base or the ceiling plate on the outside of the flange.

[0007] In addition, the flying object of one embodiment of the present invention includes a suction cup, a suction mechanism, and a mechanism for holding and rotating the fire detector body, and while the suction mechanism is used to suck the inside of the suction cup and adhere to and fix the fire detector body to the periphery of the detector base, the fire detector body can be rotated by the holding and rotating mechanism to attach it to or remove it from the detector base. The periphery of the detector base that is adhered to may be the flange of the detector base or the ceiling panel on the outside of the flange. Effect of the Invention

[0008] According to the present invention, in the case of a fire detector installed at a high place, the fire detector main body can be removed from the detector base or attached to the detector base by a flying robot such as a multicopter. [Brief description of the drawings]

[0010] In the following description, the up-down direction will be described based on the direction when the fire detector is installed on the ceiling.

[0011] First, a fire detector to be installed according to the present invention will be described. The detector base 2 is fixed to a ceiling or the like, and the fire detector main body 1 can be attached to or detached from the detector base 2. Figure 1 shows a top view of the fire detector main body 1. On the top surface of the fire detector main body 1, cutting edge fittings 12 are attached by screws 13 to two opposing locations on the periphery of the detector back panel 11.

[0012] 2 shows an enlarged view of the cutting tool 12 shown in FIG. 2(a) is a top view of the cutting tool 12, and FIG. 2(b) is a side view of the cutting tool 12. The cutting tool 12 is configured by bending a single conductive plate to form a contact section 121, an intermediate section 122, and a fixed section 123. The section between the contact section 121 and the intermediate section 122 is bent in one direction, and the section between the intermediate section 122 and the fixing section 123 is bent in the opposite direction. The fixing section 123 is provided with a fixing screw hole 124. The fixing section 123 is fixed to the sensor back plate 11 by screwing a screw 13 into the fixing screw hole 124, and the cutting tool 12 is fixed to the sensor back plate 11.

[0013] 3 shows a bottom view of the sensor base 2. The sensor base 2 has a mounting base back plate 21 and a flange 22 provided around the mounting base back plate 21. The mounting base back plate 21 is recessed above the flange 22 and has a fitting space 23 that accommodates the upper part of the fire sensor main body 1. Furthermore, within the fitting space 23, blade receiving metal fittings 24 are provided at two opposing locations on the underside of the mounting base back plate 21. The sensor base 2 has screws 252 fitted into holes (not shown) in the mounting base back plate 21, and there is no opening to pass through to the back side inside the flange 22, including around the fitting space 23.

[0014] When attaching the fire detector main body 1 to the detector base 2 fixed to the ceiling panel C, the fire detector main body 1 is held by the worker's hand or with an attachment / detachment tool and brought close to the detector base 2 from below. Then, after inserting the upper part of the fire detector main body 1 into the fitting space 23, the fire detector main body 1 is rotated. As a result, the blade fitting 12 is sandwiched between the spring-shaped blade receiving fitting 24, and the fire detector main body 1 is attached to the detector base 2. In addition, in the attached state, the worker can remove the fire detector main body 1 from the detector base 2 by rotating the fire detector main body 1 in the opposite direction to that at the time of attachment. EXAMPLES

[0015] In the first embodiment, instead of an operator attaching and detaching the fire detector main body 1 to and from the detector base 2 by hand or with an attachment / detachment device, the attachment and detachment are performed using a multicopter 3 and an aircraft mounting unit 4. Fig. 4 shows a situation in which the aircraft, the multicopter 3, approaches the detector base 2 in the aircraft mounting unit 4 of the first embodiment.

[0016] The upper part of Fig. 4 shows a schematic cross-sectional view of the detector base 2 fixed to a ceiling board C. The tip of the pressing piece 251 of the fixing member 25 is lowered by tightening the screw 252. The detector base 2 is fixed to the ceiling board C by clamping the ceiling board C between the flange 22 and the tip of the pressing piece 251 of the fixing member 25. The mounting base rear plate 21 is recessed above the flange 22, and includes a fitting space 23 that accommodates the upper part of the fire detector main body 1. Furthermore, within the fitting space 23, blade receiving metal fittings 24 are provided at two opposing locations on the lower side of the mounting base rear plate 21.

[0017] At the bottom of FIG. 4, a multicopter 3 approaching the detector base 2 is depicted. The multicopter 3 is an aircraft that flies using a plurality of propellers 31. An aircraft mounting unit 4 is attached to the upper part of the multicopter 3. The aircraft mounting unit 4 in FIG. 4 is depicted in a schematic cross-sectional view. In the aircraft mounting unit 4, a suction cup part 43 is provided on a unit base 41, and a holding and rotating mechanism 42 is provided inside the suction cup part 43. The holding and rotating mechanism 42 has a fixed base part 422 at the lower part removably fixed to the unit base 41. The fixed base part 422 has a square outer periphery, and is accommodated and fixed in a square recess provided in the center of the upper surface of the unit base 41. The fixed base part 422 is provided with a rotating device (not shown) that rotates the upper rotating base 421. The fire detector main body 1 is placed on the upper part of the rotating base 421. The top surface of the rotating base 421 is provided with anti-slip rubber (not shown), so that the fire detector main body 1 rotates together with the rotating base 421 without slipping when the rotating base 421 rotates. Also, a suction mechanism 44 is provided inside the unit base 41. The suction mechanism 44 sucks in the air inside the suction cup portion 43 and releases it to the outside.

[0018] When the fire detector main body 1 is mounted on the unit 4 for mounting on an aircraft and the multicopter 3 is flown by an operator, and the suction cup portion 43 comes into contact with the flange 22, the state becomes as shown in FIG. 5. The upper end abutment surface of the suction cup portion 43 comes into contact with the annular flange 22, thereby positioning the fire detector main body 1 mounted on the holding and rotating mechanism 42. Then, in the state shown in FIG. 5, the suction mechanism 44 sucks the inside of the suction cup portion 43. Since there is no opening on the inside of the flange 22, the suction of the suction mechanism 44 reduces the pressure inside the suction cup portion 43. The flange 22 is formed to be wide in the radial direction so that the suction cup portion 43 can easily come into contact with it.

[0019] The unit 4 to be mounted on an aircraft is then attached to and fixed to the flange 22 provided around the detector base 2. Fig. 6 shows the state in which the suction cup 43 is deformed by suction in the unit 4 to be mounted on an aircraft of the first embodiment. The suction mechanism 44 sucks the inside of the suction cup 43, causing the pressure inside to drop and the suction cup 43 to deform, lifting up the unit base 41. The holding and rotating mechanism 42 on the unit base 41 and the fire detector main body 1 on top of that also rise up, and the fire detector main body 1 enters the fitting space 23 shown in Fig. 5.

[0020] When the fire detector main body 1 reaches the upper end, an operator remotely operates the rotation device provided on the fixed base 422 of the holding and rotating mechanism 42, causing the rotating base 421 to rotate clockwise as viewed from below. At this time, since the fixed base 422 of the holding and rotating mechanism 42 is fixed to the flange 22 of the detector base 2 via the unit base 41 and the suction cup part 43, the multicopter 3 itself does not rotate. Therefore, sufficient torque is obtained and sufficient rotational force is transmitted to the fire detector main body 1 mounted on the rotating base 421 so as not to slip.

[0021] As a result, the two blade fittings 12 of the fire detector main body 1 fit into the two blade receiving fittings 24 of the detector base 2, and the fire detector main body 1 is attached. After the attachment is completed, the suction mechanism 44 stops, and outside air is taken into the suction cup portion 43, releasing the suction. Then, the multicopter 3 and the unit 4 for mounting on an aircraft are detached from the detector base 2, and the attachment of the fire detector main body 1 to the detector base 2 is completed.

[0022] When removing the fire detector main body 1 from the detector base 2, the steps are reversed from the attachment steps. The multicopter 3 carrying the flying object mounting unit 4 is flown, the suction cup 43 is brought into contact with the flange 22, and then the suction mechanism 44 is activated. Then, the air inside the suction cup 43 is discharged, and the flying object mounting unit 4 is fixed to the detector base 2 as shown in FIG. 6. In this state, when the operator operates the rotation device provided on the fixed base 422 of the holding and rotating mechanism 42 by remote control, the rotating base 421 rotates counterclockwise as viewed from below. At this time, since the fixed base 422 of the holding and rotating mechanism 42 is fixed to the flange 22 of the detector base 2 via the unit base 41 and the suction cup 43, the multicopter 3 itself does not rotate. Therefore, a sufficient torque is obtained, and a sufficient rotational force is transmitted to the fire detector main body 1 mounted on the rotating base 421 so as not to slip.

[0023] This causes the two blade fittings 12 of the fire detector main body 1 to come out of the two blade receiving fittings 24 of the detector base 2, and the fire detector main body 1 is removed. After removal, the suction mechanism 44 stops, and outside air is taken into the suction cup portion 43, releasing the suction. Then, the multicopter 3 and the unit 4 for mounting on an aircraft are detached from the detector base 2, and the fire detector main body 1 is carried to the worker. This completes the removal of the fire detector main body 1 from the detector base 2.

[0024] <Replacing the holding and rotating mechanism> The holding and rotating mechanism 42 has a fixed base 422 at the lower part removably fixed to the unit base 41, and is replaceable with another mechanism. In the first embodiment shown in Figs. 4 to 6, the fixed base 422, whose horizontal surface is square, is accommodated in a depression with a square horizontal surface provided in the center of the upper surface of the unit base 41, and is fixed so as not to rotate. Fig. 7 shows a configuration in which a smoke test spray 45, which is a smoke mechanism, is fixed as another mechanism. The lower part of the smoke test spray 45 is accommodated in a depression with a square horizontal surface provided in the center of the upper surface of the unit base 41 and fixed. A cover may be added to the spray can so that the periphery of the lower part of the smoke test spray 45 is square, but it does not have to be square as long as it can be accommodated in the depression of the unit base 41, and a cylindrical spray can may be fixed as it is without adding a cover.

[0025] When performing the smoke application test, the multicopter 3 is flown, and as shown in FIG. 7, the suction cup portion 43 is brought into contact with the flange 22 of the detector base 2, and then the operator remotely sends a smoke application command. Then, the mist for testing is released from the smoke application test spray 45 by the mist release mechanism (not shown). This allows the smoke application test of the fire detector main body 1 to be performed. During the smoke application test, the air vehicle mounted unit 4 does not need to be fixed by operating the suction mechanism 44. When the smoke application test is completed, the multicopter 3 can be moved up and down several times to send air into the fire detector main body 1. By moving it up and down in this way, the test smoke inside the fire detector main body 1 is quickly dispersed. Also, if the suction mechanism 44 is activated at this time, the test smoke inside the fire detector main body 1 can be removed more quickly. By using the aircraft-mounted unit 4 equipped with the smoke test spray 45 shown in Figure 7 and the multicopter 3, during the smoke test, the worker can test multiple fire detectors installed on the ceiling panel C in succession, thereby enabling an efficient smoke test. EXAMPLES

[0026] In the second embodiment as well, instead of an operator attaching and detaching the fire detector main body 1 to and from the detector base 2 by hand or with an attacher / detacher, the attachment and detachment are performed using a multicopter 3 and an aircraft mounting unit 5. Fig. 8 shows a multicopter 3, which is an aircraft, equipped with the aircraft mounting unit 5 of the second embodiment.

[0027] As shown in Fig. 8, the unit 5 to be mounted on an aircraft has a plurality of suction columns 55 provided on a unit base 51, and a suction cup portion 53 is provided at the tip of the suction column 55. In Fig. 8, two of the four suction columns 55 and suction cup portions 53 are shown. A holding and rotating mechanism 52 is provided inside the suction cup portion 53. Four suction cup portions 53 are provided at positions outside the holding and rotating mechanism 52. As long as the unit 5 to be mounted on an aircraft is fixed to the sensor base 2, the number of suction columns and suction cup portions may be any number, as long as a plurality is provided.

[0028] The holding and rotating mechanism 52 has a fixed base 522 at the lower part removably fixed to the unit base 51. The fixed base 522 has a square outer periphery and is accommodated and fixed in a square recess provided in the center of the upper surface of the unit base 51. The fixed base 522 is equipped with a rotation device (not shown) for rotating the upper rotating base 521 and a lifting device (not shown) for lifting it. The fire detector main body 1 is placed on the upper part of the rotating base 521. Since the upper surface of the rotating base 521 is provided with non-slip rubber (not shown), when the rotating base 521 rotates, the fire detector main body 1 rotates together with the rotating base 521 without slipping. In addition, the aircraft mounting unit 5 is provided with a suction mechanism 54 having a suction device 541 and a suction pipe 542. The suction device 541 is provided inside the unit base 51, and sucks air inside the suction cup part 53 from inside the unit base 51 through a suction pipe 542 provided inside the suction column 55.

[0029] When the fire detector main body 1 is attached to the detector base 2, as shown in FIG. 8, the fire detector main body 1 is mounted on the unit 5 for mounting on an aircraft, and the multicopter 3 is flown by an operator to bring the suction cup 53 into contact with the flange 22. When the suction device 541 performs suction, the air inside the suction cup 53 is sucked through the suction pipe 542. Then, the four suction cups 53 are attached to the flange 22 of the detector base 2, and the unit 5 for mounting on an aircraft is fixed to the detector base 2. In this state, the lifting device of the fixed base 522 is operated to push up the rotating platform 521. Then, after the rotating platform 521 is pushed up until the fire detector main body 1 comes into contact with the mounting base back plate 21 of the detector base 2, the rotating device of the fixed base 522 is operated to rotate the rotating platform 521 clockwise as viewed from below. At this time, since the fixed base 522 of the holding and rotating mechanism 52 is fixed to the flange 22 of the sensor base 2 via the unit pedestal 51, the suction column 55, and the suction cup portion 53, it does not rotate relative to the sensor base 2. Therefore, sufficient torque is obtained and sufficient rotational force is transmitted to the fire sensor main body 1 mounted on the rotating base 521 so as not to slip.

[0030] As a result, the two blade fittings 12 of the fire detector main body 1 fit into the two blade receiving fittings 24 of the detector base 2, and the fire detector main body 1 is attached. After the attachment is completed, the suction device 541 stops, and outside air is taken into the suction cup portion 53, releasing the suction. Then, the multicopter 3 and the unit 5 for mounting on an aircraft are detached from the fire detector, and the attachment of the fire detector main body 1 to the detector base 2 is completed.

[0031] When removing the fire detector main body 1 from the detector base 2, the steps are reversed from the attachment steps. The multicopter 3 carrying the unit 5 for mounting on an aircraft is flown, the suction cup 53 is brought into contact with the flange 22, and then the suction device 541 is activated. This causes the air inside the suction cup 53 to be discharged, and the unit 5 for mounting on an aircraft is fixed to the detector base 2. In this state, when the operator remotely operates the rotation device provided on the fixed base 522 of the holding and rotating mechanism 52, the rotating table 521 rotates counterclockwise as viewed from below. At this time, the fixed base 522 of the holding and rotating mechanism 52 is fixed to the flange 22 of the detector base 2 via the unit base 51, the suction column 55, and the suction cup 53, and therefore does not rotate. Therefore, a sufficient rotational force is transmitted to the fire detector main body 1 mounted on the rotating table 521 so as not to slip.

[0032] As a result, the two blade fittings 12 of the fire detector main body 1 come out of the two blade receiving fittings 24 of the detector base 2, and the fire detector main body 1 is removed. After the removal is complete, the suction device 541 stops, and outside air is taken into the suction cup portion 53, releasing the suction. Then, the multicopter 3 and the unit 5 for mounting on an aircraft are detached from the detector base 2, and the fire detector main body 1 is carried to the worker. This completes the removal of the fire detector main body 1 from the detector base 2.

[0033] In the first and second embodiments, the sensor base is attached to the flange, but the sensor base may be attached to the ceiling plate C on the outside of the flange. In this case, the sensor base does not need to have a flange with a wide radial width. However, it is preferable that the ceiling plate C does not have air permeability so that the aircraft mount units 4 and 5 are sufficiently fixed to the ceiling plate C by suction, and it is also preferable that the suction capacity of the suction mechanism 44 and the like is high.

[0034] In the first and second embodiments, the air vehicle on-board units 4, 5 are attached to the multicopter 3. However, the multicopter itself, which is the air vehicle, may have the configuration of the air vehicle on-board units 4, 5.

[0035] Although the examples of the present invention have been described in detail above, the specific configuration is not limited to these embodiments, and the present invention includes design changes within the scope of the present invention. The above-mentioned examples can be combined by utilizing each other's technologies as long as there are no particular contradictions or problems in the purpose and configuration.
