Description
Technical field
The present invention relates to a kind of normal temperature and hang high temperature contact detector laying method and temperature sensing hanger, this method adopts the fixing heat detector of suspender that can change detector position according to the variation of detector environment temperature of living in, improved the sensitivity of line-type heat detector greatly, overcome contact simultaneously throwing into question of line-type heat detector is installed.
Background technology
In the prior art, mode at cable testing bridge or cable bearer installation line-type heat detector has two kinds: a kind of is that suspension type is laid, another kind is that contact is laid, what accompanying drawing 1 showed is that the traditional suspension type of heat detector is laid position view, in suspension type is laid, line-type heat detector 4 is laid in directly over the cable testing bridge 5, suspension type anchor clamps 2 are installed on a fixed mount 1, line-type heat detector 4 is placed in the floating holder 3, then floating holder and suspension type anchor clamps is fixed together.In contact is laid, utilize plain clamp to be fixed on the cable testing bridge line-type heat detector, line-type heat detector and cable are contact to be fixed, and the advantage of first kind of system of laying is: can change on cable testing bridge easily or the increase cable, need not to remove line-type heat detector; Its shortcoming is: this mode can only be carried out detection alarm to the outside fire of cable on the cable testing bridge, and can't in time survey the interior fires of cable.The advantage of second kind of system of laying is: no matter to the outside fire of cable on the cable testing bridge or interior fires detection alarm accurately, its sensitivity is very high; Its shortcoming is: need remove line-type heat detector during for replacing on the cable testing bridge or increase cable, be unfavorable for the maintenance and renovation of workmen to cable.For this reason, need to propose a kind of new heat detector laying method and suspender.
Summary of the invention
The object of the present invention is to provide a kind of normal temperature to hang high temperature contact detector laying method and temperature sensing hanger, this method adopts the temperature sensing hanger that can change detector position according to the variation of detector environment temperature of living in to lay line-type heat detector, at normal temperatures line-type heat detector is hung the top that is fixed on cable testing bridge, in case environment temperature surpasses this temperature, this suspender will be opened automatically, line-type heat detector drops on the cable testing bridge automatically, no matter make line-type heat detector still is the detection sensitivity that the fire that causes of inner burning things which may cause a fire disaster possesses same grade to outside burning things which may cause a fire disaster, the false alarm that reduces line style detector itself with fail to report the police, again can the convenient construction personnel to the replacing and the maintenance of cable on the cable testing bridge.
The objective of the invention is to be realized by following technical proposals: a kind of normal temperature hangs high temperature contact detector laying method, a cable testing bridge that cable is installed is arranged, use a plurality of temperature sensing hangers with the line-type heat detector correspondence described cable testing bridge top that is laid in, be provided with temperature sensing element in the described temperature sensing hanger, when the cable temperature at described cable testing bridge place is in 40 ℃～140 ℃, described temperature sensing element action, line-type heat detector is separated with the temperature sensing hanger, make described line-type heat detector free-falling and cover the cable surface that is detected, and the contact of maintenance and described cable is surveyed.
The purpose of temperature sensing hanger of the present invention is achieved in that a kind of temperature sensing hanger that normal temperature hangs high temperature contact detector laying method that is used for, it is characterized in that: have one to hang female frame, this hangs on female frame and hangs sub-frame by one of magnetic force absorption, this hangs sub-frame and is provided with the U type conduit that holds the line-type heat detector cable, the female frame of described suspension is a permanent magnet, wherein be provided with an adsorption plane, the sub-frame of described suspension is the ferroxcube magnet, and its magnetic conversion Curie temperature is 40 ℃～80 ℃.
Compared with the prior art the present invention has following advantage:
1, because the present invention can be suspended on line-type heat detector the top of cable testing bridge at normal temperatures, therefore to maintenance, the replacing of cable or increase more convenient.Also reduced the false alarm of the line-type heat detector that contact lays itself simultaneously.
2, because the present invention has adopted the temperature sensing hanger to lay line-type heat detector; in case protected cable temperature surpasses design temperature value (between 40 ℃～140 ℃); line-type heat detector has just become the contact system of laying; advantage with contact system of laying; be that detector sensitivity has improved; and can effectively reduce the police that fails to report of line-type heat detector that suspension type lays itself, improved the reliability of line-type heat detector greatly.
3, the method and the device of the present invention's employing are applicable to cable type linear temperature-sensitive detector, optical fiber line-type heat detector, air hose line style heat detector.
