Description

  The present invention relates to a heating tester for testing a heat-sensitive fire sensor.

  2. Description of the Related Art Conventionally, there is a heating tester that performs a test by heating a fire sensor in order to perform an operation test of a heat-sensitive fire sensor that detects a fire based on the heat of the fire. The most popular heating tester uses benzine and heats by heat from catalytic combustion using platinum as a catalyst (see HK-3 and BVT9201K in Non-Patent Document 1).

  However, the above-mentioned heating tester cannot be used on the site where there is a restriction on bringing in combustible materials. Therefore, a heating tester has been devised that can heat a fire detector without using a combustible material. For example, there are a heating tester using hot water (FHT-2E in Patent Document 1 and Non-Patent Document 1) and a heating tester using chemical reaction heat of slaked lime (FHT011 in Patent Document 2 and Non-Patent Document 1).

However, a heat tester using hot water or slaked lime has a short testable time. In a heating tester using hot water, the fire detector cannot be operated when the hot water temperature falls. In addition, the heating tester using slaked lime can maintain the temperature at which the fire detector is operated only during the time when the slaked lime is added to the water. These heating testers can not be used for a long time as the heating tester using catalytic combustion, and can be used in a limited field such as an explosion-proof area, but instead of the heating tester using catalytic combustion, It was not something that could be continuously tested in buildings that were fire prevention objects. In addition, a heating tester using hot water or slaked lime has heat for a predetermined period once it is first used, and does not generate heat as necessary when necessary.
In view of the above-described problems, an object of the present invention is to provide a heating tester that can repeatedly perform an operation test by heating a fire detector repeatedly at any timing without using a combustible material.

(1) A heating tester according to the present invention is a heating tester for performing an operation test by heating a heat-sensing fire detector, and the fire detector itself generates heat by receiving specific radiation. A heating element that heats the fire detector, and heating means that emits the specific radiation to cause the heating element to generate heat, wherein the heating means indirectly heats the fire detector via the heating element. It is characterized by.

(2) Further, in the heating tester according to the present invention, in (1), the heating unit is a radiating unit that radiates any one of a microwave, an alternating magnetic field, an ultrasonic wave, and an infrared ray toward the heating body. The heating body is made of any one of a dielectric that is dielectrically heated by microwaves, a metal that is induction-heated by an alternating magnetic field, a rigid body that is vibrationally heated by ultrasonic waves, and an infrared-absorbing material that is heated by infrared rays. It is characterized by.

(3) The heating tester according to the present invention is characterized in that, in (1) and (2), a battery power supply for driving the heating means is provided.

  According to the configuration of the first aspect, the heating tester according to the present invention can repeatedly heat the fire detector at an arbitrary timing without using a combustible material. In addition, since the fire detector material is not uniform, even if it is directly heated by radiation from the heating means, it will not be a constant heating, but indirectly through a heating element of a predetermined material. Since the sensor is heated, the fire sensor can be heated constantly. Moreover, even if the radiation from the heating means is non-uniform, the fire detector is heated via the heating element, so that the fire detector can be uniformly heated. As a result, the fire detector is not overheated locally and does not burn.

  In addition, according to the configuration of the second aspect of the present invention, since the heating tester can be quickly heated by supplying power, the fire detector is repeatedly heated at an arbitrary timing to perform an operation test. be able to.

  Further, according to the configuration of the third aspect of the present invention, since the heating tester does not need to receive power from the outside during the test, it can move freely and perform the fire detector operation test. Moreover, it can be used repeatedly by charging a battery power supply as a secondary battery and charging. In addition, the battery power supply is downsized as a battery with high energy density. For example, a nickel metal hydride battery or a lithium ion battery is used in the hollow portion of the support rod, thereby improving portability and replenishing energy during repeated use. Therefore, it is not necessary to carry a supplement for the mobile phone, and the freedom of movement can be increased.

It is a figure explaining the shape and usage of a heating tester concerning the present invention. It is a figure which shows the structure of the heating tester which concerns on this invention.

Embodiment Embodiment of this invention is described based on FIG. 1, FIG.

  First, with reference to FIG. 1, the shape and usage of the heating tester 1 according to the present invention will be described.

  The heat-sensing fire detector D to be tested by the heating tester 1 of the present invention is a spot-type heat-sensing sensor installed on the ceiling surface C, for example, a constant temperature spot-type sensor. A differential spot type sensor and a compensation type spot type sensor. The heating tester 1 is attached to the end of the long support 2, and the worker H holds the support 2 to which the heating tester 1 is attached and brings the heating tester 1 close to the fire detector D from below. This is heated to activate the fire detector D, and an operation test is performed.

  Next, the configuration of the heating tester 1 according to the present invention will be described with reference to FIG. In this embodiment, a description will be given on the assumption that a radiation means for radiating microwaves is used as the heating means 1a, and a dielectric that is dielectrically heated by receiving microwave radiation is used as the heating body 1b.

  The main body exterior of the heating tester 1 is a bottomed substantially cylindrical cylindrical body, the top main body exterior facing the fire detector D opens, and the heating body 1b faces the fire detector D at the opening. The heating means 1a is provided below the heating means 1a. The main body exterior that houses the heating element 1b and the heating means 1a is provided with two shaft stoppers facing each other above the center of gravity of the heating tester 1. Moreover, when performing a test using the heating tester 1, the support 2 is attached. The support 2 is provided on the two distal ends of a rod-shaped support rod 2a, a bracket 2b that is a substantially U-shaped mounting bracket that is attached to the tip of the rod and supports the heating tester 1, and the bracket 2b. And a shaft stopping portion 2c that shafts the heating tester 1. In the heating tester 1, the two shaft locking portions on the exterior of the main body are fixed by the shaft locking portions 2c of the bracket 2b. Since the shaft stopper of the heating tester 1 is located above the center of gravity, the heating element 1b provided above the heating tester 1 always faces upward, and the fire detector D installed on the ceiling surface C It can be made to face the lower surface. Even if the inclination of the support 2 is changed, the heating element 1b always faces upward (see FIG. 1).

  The heating element 1b is a heating element that heats itself by receiving microwaves as specific radiation from below and heats the opposing fire detector D. The heating element 1b is formed in, for example, a plate-like disk shape, It is the gel pack which sealed the gel-like substance containing this. As the gel-like substance, a substance mainly composed of a superabsorbent polymer substance such as polyacrylic acid sodium salt, which is widely used for disposable diapers and cold insulation agents, can be used, but the water retention ability is equivalent or better. Other substances may be used. Any dielectric material may be used as long as it is a molecule having a dipole moment that generates heat due to intense movement by microwave radiation.

The heating means 1a is a radiation means that is provided below the heating body 1b and emits microwaves as specific radiation toward the heating body 1b, and is, for example, a magnetron. A power line 1c is connected to the heating means 1a, and electric power for driving the heating means 1a is supplied. The power line 1c penetrates the main body exterior of the heating tester 1, is introduced into a hollow portion in the support bar 2a, and is connected to a power source. The power source for driving the heating means 1a is, for example, a battery power source, and may be connected to a battery provided in a hollow portion in the support rod 2a via a switch (not shown).
The above is the configuration of the heating tester 1.

  Next, the operation of the heating tester 1 of the present invention will be described. A heating unit 1a to which a switch (not shown) is turned on and supplied with power from a power source radiates a 300 MHz to 300 GHz microwave toward the heating body 1b located above the heating unit 1a. For example, a microwave of 2450 MHz band is radiated by a magnetron.

  In the heating element 1b that receives the microwave radiation, the dielectric dipole changes with a phase lag with respect to the microwave electric field vibration, and this delay acts as a resistance force against the microwave electric field change, The dielectric dipole is heated. That is, when the dielectric is the above-described gel pack, the water molecules contained in the gel substance are vibrated and heated, and are heated by the same principle as the microwave oven.

  And the fire detector D in the position which opposes by the heat conduction or heat radiation from the heated heating body 1b is heated. The heated fire detectors D are activated when they reach their respective operating points (operating temperature, operating temperature increase rate, etc.).

  As described above, the heating tester 1 according to the present invention can quickly heat the heating element 1b at an arbitrary timing and perform an operation test when power is supplied by a switch operation without using a combustible material. Moreover, as long as there exists electric power, the fire detector D can be heated repeatedly and an operation test can be performed. If microwaves are radiated directly toward the fire detector D, the fire detector D is not standardized, so it will not be heated to a certain degree, and a powerful microwave will be emitted nearby. There is a risk of electromagnetic interference. However, since the heating tester 1 of the present invention indirectly heats the fire detector D via the heating body 1b made of a predetermined material, the fire detector D can be heated constantly. Moreover, even if the radiation from the heating means 1a is not uniform, the fire detector D is heated via the heating body 1b, so that the fire detector D can be uniformly heated. As a result, it is possible to prevent the fire detector D from being overheated locally and being burned. Further, the heating body 1b is not excessively heated by controlling the upper limit of the electric power supplied to the heating means 1a, controlling the temperature of heating by providing the heating body 1b with a heat sensitive means such as a thermostat. You may control as follows. Further, a battery power source as a power source may be carried by the worker H and power may be supplied from the outside of the heating tester 1, or a battery power source may be provided inside the support bar 2a. In the latter case, since it is not necessary to receive power from the outside during the test, the operation test of the fire detector D can be performed by moving freely. Moreover, it can be used repeatedly by charging a battery power supply as a secondary battery and charging. Furthermore, the battery power source is miniaturized as a battery with high energy density. For example, a nickel metal hydride battery or a lithium ion battery is used in the hollow portion of the support rod 2a, thereby improving portability and energy during repeated use. It is not necessary to carry a replenishment product for replenishment, and the degree of freedom of movement can be further increased.

  In the above-described embodiment, it has been described that the radiation unit that radiates microwaves is used as the heating unit 1a, and the dielectric that is dielectrically heated by receiving the microwave radiation is used as the heating body 1b. .

  A radiation means for radiating an alternating magnetic field may be used as the heating means 1a, and a metal such as iron or stainless steel that is induction-heated by the alternating magnetic field may be used as the heating body 1b. This is due to the same principle as the IH cooking heater.

  Further, a radiating unit that emits ultrasonic waves may be used as the heating unit 1a, and a rigid body that is vibrated by ultrasonic waves, such as ceramics, may be used as the heating unit 1b. This is based on the same principle as ultrasonic welding.

  Further, a radiation means for emitting infrared rays, for example, a halogen heater may be used as the heating means 1a, and an infrared absorbing material heated by infrared rays, for example, ceramics may be used as the heating body 1b. The heating element 1b may be a material that generates heat or emits far infrared rays by absorbing infrared rays emitted from the heating means 1a. For example, a dielectric can be used. The infrared ray radiated by the heating means 1a may be anything that causes the heating element 1b to generate heat by absorbing the heating element 1b or radiates far infrared rays from the heating element 1b. It is determined appropriately depending on the heating element 1b in the range of infrared rays to far infrared rays.

  In addition, the heating means 1a should just be a means to perform radiation | emission which heats the fire detector D indirectly via the heating body 1b, and is not restricted to the above-mentioned radiation means. Similarly, the heating element 1b is not limited to the above-described material as long as it can heat the fire detector D by radiation from the heating means 1a.

  As described above, according to the heating tester 1 of the present invention, an operation test can be performed by repeatedly heating the fire detector D at any timing without using a combustible material.
