Description
Technical Field
The present invention relates to a fire fighting system testing device, and more particularly, to a fire fighting system testing device without using open fire testing.
Background
Modern people often cause frequent residential fire accidents due to improper electricity and fire utilization. In order to reduce the possibility of fire, many houses or buildings are provided with fire fighting systems such as temperature sensors or sprinklers on the ceiling or at a high level, so as to alarm or extinguish the fire at the beginning of the possible fire. The fire fighting system needs to keep normal operation and transmit abnormal information to the fire fighting host, so it is important to perform regular tests on the fire fighting system.
Taking a temperature sensor as an example, conventionally, during testing, a testing device is required to heat the temperature sensor by an open fire (the open fire is defined as a heating source generating a flame), and whether the temperature sensor is activated or send an alarm message is determined along with the temperature increase. However, the conventional testing equipment needs to use the tar remover as fuel to generate flame, which not only consumes fuel cost, but also may cause the flame to burn the temperature sensor if the distance between the testing equipment and the temperature sensor is not properly held during the testing process; moreover, the flame tends to extinguish once it encounters water, and thus is also prone to distress when tested using conventional testing equipment. In addition, since the use of open fire is often limited by the current building and fire-fighting related regulations, the testing equipment cannot be used at will in many places, and some manufacturers may lay things to omit the testing operation of the fire-fighting system, which greatly increases the fire risk.

The features and advantages of the embodiments will become more fully apparent from the following detailed description and appended claims.
As used herein, the use of "a" or "an" is used to describe elements and components described herein. This is done for convenience of illustration only and to provide a general sense of the scope of the invention. Thus, unless expressly stated otherwise, such description should be read to include one or at least one and the singular also includes the plural.
As used herein, the terms "comprising," "having," or any other similar terms, are intended to cover a non-exclusive inclusion. For example, an element or structure that comprises a plurality of elements is not limited to only those elements listed herein, but may include other elements not expressly listed or inherent to such element or structure.
The fire fighting system testing device is applied to testing a fire fighting system with a temperature sensing function, and testing whether the fire fighting system normally operates or not through temperature change. Fig. 1 is a schematic diagram of a fire fighting system testing device according to the present invention. As shown in fig. 1, a fire fighting system testing device 1 of the present invention includes a testing portion 10, a grip portion 20, and a power supply unit 30. The test section 10 is used to access a fire protection system 80 to be tested, which is disposed at a ceiling or a high place, and is warmed by a heat source to perform a test. The holding portion 20 is connected to the testing portion 10, and the holding portion 20 is used for a user to hold, so as to facilitate moving the testing portion 10 to a position close to the fire fighting system 80 to be tested. The power supply unit 30 is used to supply power to the test part 10, so as to increase the temperature of the heat source of the test part 10. In an embodiment of the present invention, the fire fighting system testing device 1 further comprises a wire 40. Both ends of the wire 40 are electrically connected to the heat source of the test part 10 and the power supply unit 30, so that the power supply unit 30 can transmit power to the heat source of the test part 10 through the wire 40.
Referring to fig. 1 and fig. 2 together, fig. 2 is a schematic view of a testing part of the testing apparatus of a fire fighting system according to the present invention. As shown in fig. 1 and 2, a test unit 10 of a fire fighting system test device 1 according to the present invention includes a cover 11 and an electric heating element 12. The cover 11 includes a bottom 111 and an opening 112 disposed opposite to the bottom 111, that is, if the bottom 111 is disposed on one side of the cover 11, the opening 112 is disposed on the other side of the cover 11 opposite to the bottom 111. An accommodating space 113 is formed in the cover body 11, and the accommodating space 113 is communicated with the environment outside the cover body 11 through the opening 112, so that the fire protection system 80 to be tested can enter the accommodating space 113 through the opening 112, and the test is facilitated. In an embodiment of the present invention, the cover 11 may be a cylindrical, bowl-shaped or U-shaped structure, but the present invention is not limited thereto, and the cover 11 may also be other structures with different shapes. The cover 11 may be made of fireproof and high temperature resistant material to avoid the possibility of the cover 11 being melted down due to over high internal temperature.
The electric heating element 12 is disposed at the bottom 111 of the cover 11. The electrical heating element 12 may be converted to heat by the received electrical power to raise to a desired temperature to facilitate testing against the fire protection system 80 to be tested. Because the electric heating element 12 is heated by electric power, open fire can not be generated, so that the fire fighting system testing device 1 can improve the safety by the electric heating element 12 in use and avoid the device and the fire fighting system 80 to be tested from being burnt. In one embodiment of the present invention, the electrical heating element 12 is a ceramic heater, such as a PTC (Positive Temperature coefficient) type ceramic heater. The PTC type ceramic heater has the characteristics of temperature setting, high heat exchange efficiency, long service life, uniform temperature distribution, self constant temperature effect and the like, so that the PTC type ceramic heater can be used as a heat source which is stable and does not generate open fire. It should be noted that the electric heating element 12 may also be other electric heating elements with similar functions or characteristics, and is not limited to the embodiment.
In an embodiment of the present invention, the testing portion 10 further includes a heat sink 13. The heat dissipation fins 13 are stacked on the surface of the electric heating element 12, and the heat generated by the electric heating element 12 is conducted to the heat dissipation fins 13 through the direct contact between the heat dissipation fins 13 and the electric heating element 12. The radiator fin 13 includes a plurality of fin structures 131, and each fin structure 131 extends from the end near the electric heating element 12 toward the opening 112 end of the housing 11, so that the conductive heat received by the radiator fin 13 can be concentrated toward the opening 112 of the housing 11 through the plurality of fin structures 131. The fin heights and the fin densities of the plurality of fin structures 131 may be adjusted according to different testing requirements. In the present embodiment, the heat dissipation fins 13 may be made of aluminum, but the heat dissipation fins 13 may also be made of other metals, alloys or other heat conductive materials with similar functions or characteristics, and the present embodiment is not limited thereto.
In terms of structural design, the distance D between the radiator fins 13 and the opening 112 of the housing 11 needs to be kept,
so that the heat dissipation fins 13 do not exceed the openings 112; that is, the electric heating element 12 and the heat dissipating fins 13 are retained in the receiving space 113 of the cover 11, and after the fire protection system 80 to be tested enters the receiving space 113 through the opening 112, the fire protection system 80 to be tested does not contact the heat dissipating fins 13 and a certain space exists between the two through the reserved distance D. Thus, the fire fighting system 80 to be tested is tested by the radiant heat provided by the cooling fins 13. The distance D is approximately several centimeters (e.g., 1-2 centimeters), and can be adjusted according to different design requirements.
In one embodiment of the present invention, the test section 10 further includes an insulator 14. The insulating member 14 covers the other parts except the connection part between the electric heating element 12 and the heat dissipating fins 13, that is, the periphery and most of the surface of the electric heating element 12 are kept in an insulating state by the arrangement of the insulating member 14, and only one side surface contacts the heat dissipating fins 13 and a partial surface area is electrically connected with the wire 40. Therefore, the electric heating element 12 can concentrate the heat generated after conversion to be conducted toward the heat dissipating fins 13, so as to improve the heat conduction efficiency. In this embodiment, the insulating member 14 may be made of a material having heat insulating and electrically insulating properties.
Fig. 3 is a schematic view of a testing portion of a testing device of a fire fighting system according to another embodiment of the present invention. As shown in fig. 3, in the present embodiment, the test section 10a of the fire fighting system test device 1 of the present invention further includes a height adjusting mechanism 15. The height adjusting mechanism 15 can be coupled to the electric heating element 12 for adjusting the height of the electric heating element 12 relative to the bottom 111 of the housing 11, thereby changing the distance D between the heat dissipation fins 13 and the opening 112 of the housing 11. Therefore, in response to different types or installation positions of the fire protection systems 80 to be tested, the user can adjust the height of the electric heating element 12 to a suitable height by the height adjusting mechanism 15, so as to perform corresponding testing operations by using the fire protection system testing device 1 of the present invention. The height adjusting mechanism 15 may be a combination of different structural members, such as a sliding member and a sliding groove, a rotating member and a gear, or other structural members capable of generating height displacement.
Referring to fig. 1 and 2, in an embodiment of the present invention, the holding portion 20 may be a rod with a fixed length, one end of the rod is directly connected to the testing portion 10, and the other end of the rod is connected to the testing portion
For the user to hold. The rod member may be made of a light and heat-resistant material such as a metal or alloy,
Plastic materials or other materials with similar properties, etc.
The power supply unit 30 is electrically connected to the electric heating element 12 of the testing part 10 through the wire 40, so that the power supply unit 30 can directly transmit power to the electric heating element 12 for electric-thermal conversion. In an embodiment of the present invention, the power supply unit 30 is a battery module capable of storing power, such as a lithium iron battery. The lithium iron battery has the characteristics of large electric capacity, high discharge power, quick charge, high stability in a high-temperature environment and the like, so that the lithium iron battery can be used as a stable power supply source. It should be noted that the power supply unit 30 may also adopt other power supply units with similar functions or characteristics, and is not limited to the embodiment. According to different design requirements, the power supply unit 30 can also adopt a module design capable of being externally connected with a power supply, and power is supplied by utilizing a socket in a building.
The wire 40 may be an electrical transmission wire that can transmit a relatively large current to heat the electrical heating element 12 to a set temperature in a short period of time. In an embodiment of the present invention, the wire 40 is disposed separately from the grip portion 20, and the electric heating element 12 of the self-test portion 10 directly extends to the power supply unit 30.
Fig. 4 is a schematic diagram of a fire fighting system testing device according to another embodiment of the present invention. As shown in fig. 4, in the present embodiment, the grip portion 20 of the fire fighting system testing device 1a of the present invention includes a hollow structure 21. The wire 40 may be hidden within the grip portion 20 through the hollow structure 21 to reduce the possibility that the exposed wire 40 will affect the overall operation or movement of the fire protection system testing device 1a of the present invention. In addition, in the present embodiment, the grip portion 20 may further include a telescopic structure 22 with a changeable length. By the arrangement of the telescopic structure 22, the user can easily adjust the total length of the grip portion 20 to test fire protection systems 80 to be tested at different heights.
Fig. 5 is a schematic diagram of a fire fighting system testing device according to another embodiment of the present invention. As shown in fig. 5, in this embodiment, the fire fighting system testing device 1b of the present invention further includes a pivot mechanism 50. The pivot mechanism 50 is disposed at a connection position of the testing portion 10 and the holding portion 20, so that the testing portion 10 can rotate relative to the holding portion 20 through the pivot mechanism 50 to change a testing angle.
Therefore, the fire fighting system testing device provided by the invention utilizes the electric heating element to carry out electric heating conversion, and generates a heat source area with stable temperature between the heat dissipation fins and the opening of the cover body to test the fire fighting system to be tested, so that the traditional testing device using open fire test is replaced, and the safety and the testing efficiency of the fire fighting system test are greatly improved. In addition, through different structural designs of the testing part or/and the holding part, the use flexibility and the convenience of the fire fighting system testing device are improved, so that the fire fighting systems to be tested in different forms or arrangement positions can be tested.
