Description

Technical Field

[0001] The present disclosure relates to a smoke addition tester applied to an operation confirmation test of a smoke detector, and particularly to a smoke addition tester having a covering portion provided so as to surround the periphery of a smoke generating device.

Background Art

[0002] There is a smoke detector installed in a fire monitoring area that senses a fire at an early stage by sensing smoke. Smoke detectors are often installed at high places such as the ceiling in a building, and a dedicated smoke addition tester for performing an operation confirmation test of the smoke detector is prepared (see, for example, Patent Document 1).

[0003] The conventional smoke addition tester disclosed in Patent Document 1 enables an operation confirmation test of a smoke detector installed at a high place by using a support rod with a smoke generating body attached to its tip. In this conventional smoke addition tester, a detachable cover that covers the smoke generating body is provided.

[0004] The cover covers the smoke detector installed on a ceiling material or the like and serves to fill the inside with simulated smoke released from the smoke generating body, and is formed of a material such as a synthetic resin. Further, in order to give the cover elasticity, a part in the height direction is bellows-shaped.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The smoke detector targeted for the operation confirmation test may have a state where the pipe covering the wiring is exposed along the ceiling depending on the installation location. Thus, when applying the conventional smoke addition tester according to Patent Document 1 in a situation where there are pipes or the like partially around the smoke detector, the height of the pipe portion can be absorbed by the contraction of the bellows-shaped portion.

[0007] However, since the cover contracts entirely in the height direction, a gap is formed between the ceiling surface and the cover in the portion without pipes, and it is impossible to fill the ceiling surface and the cover without a gap, which may cause the test smoke to leak. As a result, the operation confirmation test of the smoke detector could not be performed with high accuracy.

[0008] Such a problem of test smoke leakage occurs not only when the smoke detector is installed at a high place such as the ceiling, but also when the installation surface of the smoke detector is not flat around the smoke detector.

[0009] The present disclosure has been made to solve the above problems, and in various installation environments, even when the installation surface around the smoke detector is not flat and there are protrusions such as pipes partially, it is possible to suppress the leakage of test smoke and obtain a smoke addition tester having a configuration capable of performing the operation confirmation test quickly and with high accuracy.

Means for Solving the Problems

[0010] The smoke addition tester according to the present disclosure includes a smoke generating device that generates test smoke, a base that supports the smoke generating device, and a cover portion that is connected to the base so as to surround the periphery of the smoke generating device. The cover portion has a plurality of buffer members that are independent and bend in parallel in the circumferential direction.

Effects of the Invention

[0011] According to the present disclosure, in various installation environments, even when the installation surface around the smoke detector is not flat and there are protrusions such as pipes partially, it is possible to suppress the leakage of test smoke and obtain a smoke addition tester having a configuration capable of performing the operation confirmation test quickly and with high accuracy.

Modes for Carrying Out the Invention

[0013] Hereinafter, preferred embodiments of the smoke addition tester of the present disclosure will be described with reference to the drawings. The smoke addition tester according to the present disclosure is characterized in that a covering portion arranged so as to surround the periphery of a smoke generating device has a plurality of buffer members that are arranged in parallel in the circumferential direction and independently bend.

[0014] Note that the smoke addition tester according to the present disclosure is not limited to being used by being attached to the tip of the support rod. When used alone or when mounted on a flying robot such as a drone, various applications according to the installation environment are possible.

[0015] As a result of having such a covering portion, even when the installation surface around the smoke detector is not flat and there are protrusions such as pipes partially, it is possible to suppress the occurrence of gaps through which the test smoke leaks, and it becomes possible to quickly and accurately perform the operation confirmation test in various installation environments.

[0016] Embodiment 1. FIG. 1 is an explanatory diagram showing a schematic configuration of a smoke addition tester according to Embodiment 1 of the present disclosure. The smoke addition tester 100 according to Embodiment 1 includes a smoke generating device 10, a base 20, and a covering portion 30.

[0017] The smoke generating device 10 is a device that generates test smoke for performing an operation confirmation test of the smoke detector, and is supported by the base 20. The covering portion 30 is connected to the outer periphery of the base 20 so as to surround the periphery of the smoke generating device 10. This covering portion 30 is characterized by having a plurality of buffer members that are independent and bend in parallel in the circumferential direction.

[0018] By using the covering portion 30 having such characteristics, even when the installation surface around the smoke detector is not flat and there are protrusions such as pipes partially, it is possible to suppress the occurrence of gaps through which the test smoke leaks. Note that in FIG. 1, such characteristics of the covering portion 30 are not accurately shown, but the characteristic configuration of the covering portion 30 will be described in detail in FIGS. 2 and later.

[0019] Using FIGS. 2 to 4, the configuration of the plurality of buffer members constituting the covering portion 30 will be described in detail. FIG. 2 is an explanatory diagram showing a state in which a plurality of buffer members 31 according to Embodiment 1 of the present disclosure are connected to the outer periphery of the base 20.

[0020] More specifically, FIG. 2(A) is a top view of a state where each of the plurality of buffer members 31 is connected to the outer periphery of the base 20, as viewed from the side of the smoke detector that is the subject of the operation confirmation test. Further, FIG. 2(B) is a side view showing a state where each of the plurality of buffer members 31 is fixedly connected to the outer periphery of the base 20 by the loop fixing portion 21. Furthermore, FIG. 2(C) is a perspective view showing the states of FIGS. 2(A) and 2(B) three-dimensionally.

[0021] FIG. 3 is an explanatory view showing the detailed shape of the buffer member 31 according to Embodiment 1 of the present disclosure. More specifically, FIG. 3(A) shows the shape when the single buffer member 31 is developed on a plane. Further, FIG. 3(B) shows the shape of a series of buffer members 32 when the covering portion 30 formed on the outer periphery of the base 20 is developed on a plane.

[0022] FIG. 4 is an explanatory view showing a state where one end portion 31a and the other end portion 31b are connected with respect to the single buffer member 31 according to Embodiment 1 of the present disclosure. Specifically, in FIG. 4, three views, namely, (A) a front view, (B) a cross-sectional view, and (C) a perspective view, are shown.

[0023] The plurality of buffer members 31 according to Embodiment 1 shown in FIGS. 2 to 4 can each be formed as a plurality of flexible film members 31 formed in a strip shape. Each of the plurality of film members 31 has a front surface and a back surface, and as shown in FIG. 3(A), has one end portion 31a and the other end portion 31b as end portions in the longitudinal direction of the strip.

[0024] Then, as shown in FIG. 4, each individual film member 31 is formed in a drip shape such that the back surface of one end portion 31a and the back surface of the other end portion 31b face each other as end portions, and as shown in FIG. 2, the end portions in the drip shape are fixedly connected to the outer periphery of the base 20 by the loop fixing portion 21.

[0025] As shown in FIG. 3, each of the plurality of film members 31 can be formed such that the width ΔWb of the other end portion 31b is narrower than the width ΔWa of one end portion 31a by providing a tapered portion 31c that varies the width. When using the film member 31 formed in this way, the one end portion 31a having a wider width ΔWa has a characteristic of being less likely to bend than the other end portion 31b having a narrower width ΔWb.

[0026] Therefore, at the end portion in the shape of a drip, the one end portion 31a is arranged on the inner side and the other end portion 31b is arranged on the outer side so that the one end portion 31a is closer to the base 20 than the other end portion 31b, and by connecting to the base 20, when the plurality of film members 31 are pressed against the installation surface of the smoke detector, it becomes possible to bend the plurality of film members 31 radially outward of the base 20.

[0027] In this way, when the plurality of film members 31 are pressed against the installation surface of the smoke detector, by bending the plurality of film members 31 radially outward of the base 20, it is possible to prevent the film members 31 from interfering with the smoke detector, and the test smoke generated by the smoke generating device 10 can be reliably supplied to the smoke detector.

[0028] Further, when arranging the plurality of film members 31 on the outer periphery of the base 20, the series of buffer members 32 shown in FIG. 3(B) can be used. The series of buffer members 32 shown in FIG. 3(B) exemplifies the case of having a plurality of film members 31(1) to 31(26) composed of 26 sheets. The series of buffer members 32 has a connecting portion 32a at the one end portion 31a where the adjacent one end portions 31a are connected to each other.

[0029] Therefore, the covering portion 30 shown in FIG. 2(B) can be formed using the series of buffer members 32 shown in FIG. 3(B) by the following procedures 1 and 2. Procedure 1: For each of the individual film members 31(1) to 31(26) constituting the series of buffer members 32 shown in FIG. 3(B), a drip shape is formed such that the back surface of the one end portion 31a and the back surface of the other end portion 31b face each other as end portions (see FIG. 4).

[0030] Step 2: Arrange a series of buffer members 32 with a drip shape formed thereon on the outer peripheral portion of the base 20 such that one end portion 31a is on the inner side and the other end portion 31b is on the outer side, and connect them to the outer peripheral portion of the base using the loop fixing portion 21. As a result, the covering portion 30 shown in FIG. 2(B) can be easily formed.

[0031] The covering portion 30 thus formed has a plurality of film members 31 that are arranged in parallel in the circumferential direction and independently bend. Therefore, even when the installation surface around the smoke detector is not flat and there are protrusions such as pipes partially, the film members 31 in the portions corresponding to the protrusions can bend more independently than the portions without protrusions, and it is possible to suppress the leakage of the test smoke.

[0032] As described above, according to the first embodiment, there is provided a smoke addition tester including a smoke generating device that generates test smoke, a base that supports the smoke generating device, and a covering portion that is connected to the base so as to surround the periphery of the smoke generating device, and the covering portion has a configuration including a plurality of buffer members that are arranged in parallel in the circumferential direction and independently bend.

[0033] As a result, in various installation environments, even when the installation surface around the smoke detector is not flat and there are protrusions such as pipes partially, it is possible to suppress the formation of a gap between the installation surface and the covering portion, suppress the leakage of the test smoke to the outside of the covering portion, and obtain a smoke addition tester that can perform the operation confirmation test quickly and with high accuracy.

[0034] Furthermore, a film member can be adopted for each of the plurality of buffer members, and for each of the plurality of film members, the width of the other end portion can be made narrower than the width of the one end portion, and the back surfaces of the one end portion and the other end portion can be made to face each other at the end portions.

[0035] By using a plurality of film members having such a shape, when bending independently in parallel in the circumferential direction, the plurality of film members can be bent outward in the radial direction of the base, and when the film members are bent, it is possible to prevent interference with the smoke detector, and it is possible to efficiently guide the test smoke to the smoke detector.

[0036] Embodiment 2. In the second embodiment, a case will be described in which the covering portion 30 has a two-layer structure including a first-layer film member 31L configured as a plurality of film members 31 and a second-layer film member 31S configured as a plurality of film members 31.

[0037] FIG. 5 is an explanatory diagram showing a comparison of the single-piece shapes of the first-layer film member 31L and the second-layer film member 31S that constitute a plurality of buffer members 31 according to the second embodiment of the present disclosure. More specifically, the total length LL of the first-layer film member 31L shown in FIG. 5(A) is formed longer than the total length LS of the second-layer film member 31S shown in FIG. 5(B).

[0038] FIG. 6 is an explanatory diagram showing a state in which one end portion 31a and the other end portion 31b are connected with respect to each of the single-piece first-layer film member 31L and the single-piece second-layer film member 31S according to the second embodiment of the present disclosure.

[0039] Specifically, in the upper part of FIG. 6, for the single-piece first-layer film member 31L, three views, namely, (A1) a front view, (B1) a cross-sectional view, and (C1) a perspective view, are shown. Similarly, in the lower part of FIG. 6, for the single-piece second-layer film member 31S, three views, namely, (A2) a front view, (B2) a cross-sectional view, and (C2) a perspective view, are shown.

[0040] The plurality of buffer members 31 having a two-layer structure according to the second embodiment shown in FIGS. 5 and 6 can be formed as a flexible first-layer film member 31L and a second-layer film member 31S, each formed in a strip shape. Each of the first-layer film members 31L and each of the second-layer film members 31S have a front surface and a back surface, and as shown in FIGS. 5(A) and 5(B), have one end 31a and the other end 31b as the longitudinal ends of the strip shape.

[0041] And each of the individual first-layer film members 31L and each of the individual second-layer film members 31S are formed in a drip shape such that the back surface of one end 31a and the back surface of the other end 31b face each other as shown in FIG. 6, and the drip-shaped ends are fixedly connected to the outer periphery of the base 20 by the loop fixing portion 21.

[0042] As shown in FIG. 5, each of the first-layer film members 31L and each of the second-layer film members 31S can be formed such that the width ΔWb of the other end 31b is narrower than the width ΔWa of the one end 31a. When using the film member formed in this way, the one end 31a having a wider width ΔWa has a characteristic that is less likely to bend than the other end 31b having a narrower width ΔWb.

[0043] FIG. 7 is an explanatory diagram showing a state in which each of the first-layer film members 31L and each of the second-layer film members 31S configured as a two-layer structure according to the second embodiment of the present disclosure are connected to the outer periphery of the base 20.

[0044] More specifically, FIG. 7(A) is a top view seen from the side of the smoke detector, which is the subject of the operation confirmation test, of the state in which each of the first-layer film members 31L and each of the second-layer film members 31S are connected to the outer peripheral portion of the base 20.

[0045] In particular, the first-layer film member 31L and the second-layer film member 31S having a two-layer structure are laminated such that the cut portions 33 of the film members adjacent to each other formed in a strip shape in the second-layer film member 31S are covered by the film member formed in a strip shape in the first-layer film member 31L.

[0046] That is, the second-layer film member 31S having a drip shape is disposed inside, and the first-layer film member 31L having a drip shape is disposed outside thereof so as to shift in the circumferential direction and cover the cut portion 33, thereby forming a two-layer structure. Since the cut portion 33 is difficult to visually recognize in FIG. 7(A), the reference numeral 33 is shown in FIG. 7(B).

[0047] Moreover, FIG. 7(B) is a side view showing the two-layer structure shown in FIG. 7(A) as viewed from the side. Further, FIG. 7(C) is a perspective view showing the states of FIGS. 7(A) and 7(B) three-dimensionally.

[0048] Also in the second embodiment, at each of the drip-shaped ends of the first-layer film member 31L and the second-layer film member 31S, one end portion 31a is arranged to be closer to the base 20 than the other end portion 31b, so that one end portion 31a is on the inner side and the other end portion 31b is on the outer side.

[0049] The state where the other end portion 31b is disposed outside and is fixedly connected to the base 20 by the loop fixing portion 21 is shown in FIGS. 7(B) and 7(C).

[0050] By adopting such a connection configuration, when the first-layer film member 31L and the second-layer film member 31S having a two-layer structure are pressed against the installation surface of the smoke detector, both the first-layer film member 31L and the second-layer film member 31S disposed inside the first-layer film member 31L can be bent radially outward of the base 20.

[0051] Thus, when the film member 31L of the first layer and the film member 31S of the second layer, which have a two-layer structure, are pressed against the installation surface of the smoke detector, by deflecting the film member 31L of the first layer and the film member 31S of the second layer outward in the radial direction of the base 20, it is possible to prevent the film member 31L of the first layer and the film member 31S of the second layer from interfering with the smoke detector, and the test smoke generated by the smoke generating device 10 can be reliably supplied to the smoke detector.

[0052] Furthermore, by adopting a two-layer structure, the cut portion 33 of the film members adjacent to each other in the film member 31S of the second layer is covered by the film member 31L of the first layer, and it is possible to suppress smoke from leaking to the outside of the covering portion 30 more effectively than in the single-layer structure of the first embodiment.

[0053] As described above, according to the second embodiment, the same effects as those of the first embodiment can be achieved. Furthermore, by forming the covering portion into a two-layer structure, it is possible to suppress test smoke from leaking to the outside of the covering portion, and it becomes possible to perform the operation confirmation test of the smoke detector more quickly and with higher precision.

[0054] Embodiment 3. In the third embodiment, a case where the smoke addition tester described in the first or second embodiment is mounted on a flying robot such as a drone and used will be described.

[0055] FIG. 8 is an explanatory diagram showing a configuration example of a smoke addition test apparatus according to the third embodiment of the present disclosure. Specifically, the smoke addition test apparatus 1 according to the third embodiment mounts the smoke addition tester 100 described in the first or second embodiment on a flying robot 200 and has a configuration that can perform an operation confirmation test of a smoke detector installed at a high place based on remote control by a remote controller 2.

[0056] The flying robot 200 is a multi-copter type unmanned aerial vehicle that can fly by remote operation with a remote controller 2, and a drone is taken as an example. The tester can conduct an operation confirmation test by flying the flying robot 200 equipped with the smoke addition tester 100 according to the installation position of the smoke detector to be tested installed on the ceiling or the like.

[0057] FIG. 9 is an explanatory diagram regarding a method for conducting an operation confirmation test of a smoke detector installed at a high place using the smoke addition test apparatus 1 according to Embodiment 3 of the present disclosure. In FIG. 9, a case where two smoke detectors 3(1) and 3(2) that are the objects of the operation confirmation test are installed on the high ceiling surface 4 is illustrated.

[0058] Furthermore, FIG. 9 shows a state where there is a pipe 5 that partially covers the wiring around the smoke detectors 3(1) and 3(2). More specifically, for the smoke detector 3(1), there are pipes 5 on both the left and right sides on the paper surface of FIG. 9, and for the smoke detector 3(2), a case where there is a pipe 5 only on the left side on the paper surface of FIG. 9 is illustrated.

[0059] The smoke addition tester 100 mounted on the flying robot 200 has a plurality of buffer members 31 that are arranged in parallel in the circumferential direction and independently bend as described in the previous Embodiments 1 and 2. Therefore, even when the installation surface around the smoke detectors 3(1) and 3(2) is not flat and there are protrusions such as pipes 5 partially, it is possible to suppress the occurrence of gaps where the test smoke leaks outside the covering portion 30, and it becomes possible to quickly and accurately conduct the operation confirmation test in various installation environments.

[0060] To conduct an operation confirmation test on the smoke detectors 3(1) and 3(2) in such an installation state using the smoke addition test apparatus 1 according to Embodiment 3 of the present disclosure, the tester 6 sequentially executes the following procedures.

[0061] In the following description, the operation confirmation test will be carried out in the order of the smoke detector 3(1) and the smoke detector 3(2). Also, in the third embodiment, it is assumed that the smoke generating device 10 can remotely control the generation / stop of test smoke based on the remote operation by the remote controller 2.

[0062] <Step 1: Installation of the smoke addition test device 1 on the ground> The tester 6 installs the smoke addition test device 1 at a ground position where it is easy to access the smoke detector 3(1) for which the operation confirmation test is to be performed first.

[0063] <Step 2: Conducting the operation confirmation test of the smoke detector 3(1)> The tester 6 operates the remote controller 2 to fly the flying robot 200 equipped with the smoke addition tester 100 along a desired route towards the smoke detector 3(1) which is the object of the first operation confirmation test. In FIG. 9, the first route R1 and the second route R2 are illustrated as the desired routes.

[0064] For example, when there are flight obstacles such as pipes and lighting on the path of the first route R1, the tester 6 can select the second route R2 to avoid the flight obstacles and move the flying robot 200 towards the smoke detector 3(1) which is the object of the operation confirmation test.

[0065] Regardless of whether the first route R1 or the second route R2 is selected, the tester 6 can adjust the smoke generating device 10 to a desired relative position with respect to the smoke detector 3(1) by remotely controlling it with the remote controller 2 so as to raise the flying robot 200 from directly below the smoke detector 3(1).

[0066] At this time, since the covering portion 30 has flexibility, even when the flying robot 200 is raised to a position where the surrounding of the smoke detector 3(1) is covered by the covering portion 30, it is possible to mitigate the situation where the flying robot 200 enters an overload state due to the covering portion 30 contacting the ceiling surface 4.

[0067] Furthermore, even in the region where the pipe 5 exists, the surrounding of the smoke detector 3(1) can be covered by the covering portion 30 in a state where the leakage of the test smoke to the outside is suppressed by the partial bending of the buffer member.

[0068] After the relative alignment of the smoke generating device 10 with respect to the smoke detector 3(1) is completed, the tester 6 can remotely perform the operation confirmation test of the smoke detector 3(1) by operating the smoke generating device 10 by remote control using the remote controller 2 to generate test smoke.

[0069] In addition, in order to easily visually recognize the state in which the confirmation lamp of the smoke detector 3 to be tested is lit as a result of performing the operation confirmation test, it is effective to make the plurality of film members 31 of a transparent material.

[0070] Also, in order to easily perform the control of the relative alignment and the confirmation of the confirmation lamp, it is conceivable to adopt a configuration in which a camera is mounted on the flying robot 200 and the image captured by the camera is confirmed on the display monitor provided on the remote controller 2 side.

[0071] By having such a configuration, even when it is difficult to control the relative alignment from the ground, or when it is difficult to directly visually recognize the confirmation lamp of the smoke detector 3(1) from the ground, the tester 6 can visually recognize the image displayed on the display monitor of the remote controller 2, and thus can more easily and accurately perform the control of the relative alignment and the confirmation of the confirmation lamp.

[0072] <Procedure 3: Conducting the operation confirmation test of the smoke detector 3(2)> After the operation confirmation test of the smoke detector 3(1) is completed in Procedure 2, the tester 6 operates the remote controller 2 to fly the flying robot 200 equipped with the smoke addition tester 100 along a desired route toward the smoke detector 3(2) which is the target of the next operation confirmation test. In FIG. 9, the third route R3 is illustrated as the desired route.

[0073] In Step 3, in order to conduct an operation confirmation test of the smoke detector 3(2), the specific remote operation performed by the tester 6 using the remote controller 2 is substantially the same as the remote operation described in Step 2, and thus the description thereof is omitted.

[0074] Also, although not shown in the figure, after the operation confirmation test of the smoke detector 3(2) in Step 3 is completed, the tester 6 performs a remote operation to land the flying robot 200 on the ground by operating the remote controller 2.

[0075] As described above, according to Embodiment 3, by adopting the configuration as shown in FIG. 8, it is possible to realize a smoke addition tester that can easily perform an operation confirmation test of a smoke detector installed at a high place in various installation environments without using a support rod.

[0076] In addition, when a camera is mounted on the flying robot, the tester can easily perform control of the relative alignment of the smoke generating device with respect to the smoke detector and confirmation of the confirmation light of the smoke detector when performing the operation confirmation test by visually recognizing the image displayed on the remote controller.

[0077] Note that when flying the flying robot 200 equipped with the smoke addition tester 100 to perform the operation confirmation test, it is important to adopt a configuration that avoids a situation where the drip-shaped portions of the film members 31, 31L, 31S shown in FIG. 4 or FIG. 6 are caught by other objects and the flight becomes impossible.

[0078] Referring to FIGS. 7(B) and 7(C) shown above, it shows a state where the other end portion 31b disposed outside the one end portion 31a is fixedly connected to the base 20 by the loop fixing portion 21. In such a connection state, as described above, there is a possibility that the drip-shaped portion may be caught by other objects and the flight may become impossible.

[0079] Therefore, in order to avoid such a non-flying state, the following configuration can be considered for each of the film members 31, 31L, and 31S. Specifically, a cut is provided at one end 31a into which the tip portion of the other end 31b can be inserted. Then, by inserting the tip portion of the other end 31b into the cut at the one end 31a, a drip shape is formed. Further, only the end of the one end 31a is fixedly connected by the loop fixing portion 21, and the other end 31b is not fixed by the loop fixing portion 21.

[0080] As a result, even when an interference state occurs in which the drip-shaped portion is caught by another object for some reason, the other end 31b comes out of the cut portion of the one end 31a and the drip shape is opened, thereby avoiding a situation where the flying robot 200 becomes unable to fly.
