Embodiment 1

[0023] Such as figure 1 , a flame detection device that is easy to adjust the distance relative to the detection point, including a detector body 1, a cooling part and a fixing part, the detector body 1 includes a casing, the casing is in a cylindrical structure, and the two ends of the cooling part respectively connected to the opening end and the fixed part of the housing of the detector body 1;

[0024] The cooling part includes two air ducts 8 connected in series and an adjustment part for adjusting the length of the cooling part. The tube 3 is provided with through holes running through its two ends, and one end of the two air pipes 8 extends into the tightening tube 3 from different ends of the through holes respectively, and the two air tubes 8 pass through a hoop 7 and the tightening tube respectively. 3 fixedly connected, any position on the air duct 8 is also provided with an air inlet 4;

[0025] The fixed part includes a mounting plate 5, the free end of an air d...

Embodiment 2

[0029] The present embodiment is further limited on the basis of embodiment 1, as figure 1 , in order to make the cooling part in the present invention have a longer length adjustment range, the air pipes 8 at both ends of the clamping tube 3 are circular pipes, and the diameters of the two air pipes 8 are different in diameter, and the air pipe with a larger diameter 8 are sleeved on the air duct 8 with a smaller diameter. At the same time, the contact between the inner and outer sides of the two air ducts 8 is also beneficial to the rigidity of the cooling part and its ability to support the detector body 1 .

[0030] In order to make the two air pipes 8 have a compact fit relationship, which is beneficial to ensure the position of the detector body 1 relative to the monitoring point, and is beneficial to the detection effect of the present invention, the distance between the two air pipes 8 in the cooling part is not greater than 0.3mm.

[0031] In this embodiment, in orde...

Embodiment 3

[0033] The present embodiment is further limited on the basis of embodiment 1, as figure 1 , in order to prevent the formation of cooling wind dead angle on the housing of the detector body 1, the number of the air outlets 2 is multiple. That is, a plurality of air outlets 2 are set on the outer casing of the detector body 1, so that there is flowing cooling air at each position in the outer casing. Furthermore, in places where forced cooling is required, more dense outlets can be arranged on the outer casing. Air outlet 2 or outlet 2 with larger outlet.

Pipe and adjustment part, the adjustment part includes a clamping tube and two hoops, the clamping tube is provided with through holes through both ends; the fixing part includes a mounting plate, a free end of an air duct and the opening of the detector body shell One end is fixedly connected, and the other free end of the air duct is fixedly connected to the mounting plate; the outer shell of the detector body is also provided with an air outlet. The structure of the present invention is simple, and the detector body has good spacing adjustment performance relative to the monitoring point, which can facilitate the installation of the present invention and the spacing adjustment during use; at the same time, the structure of the present invention is conducive to ensuring the long-term sensitivity and excellent performance of the present invention. cooling effect.

Description

technical field [0001] The invention relates to a safety monitoring device for supervising flame conditions, in particular to a flame detection device whose distance relative to a detection point can be easily adjusted. Background technique [0002] At present, there are gaseous or solid combustibles in chemical plants, oil refineries, substations, industrial warehouses, and even common diesel generator rooms used as emergency power sources, people's living environments, whether it is numerous industrial control equipment or complex Living environment, if the fire is strictly monitored in these occasions, it will provide great protection for property protection and people's life safety. [0003] Flame detector, also known as photosensitive fire detector, is a fire detector used to respond to the light characteristics of fire, that is, to detect the light intensity of flame burning and the flicker frequency of flame. In the prior art, flame detection devices are generally in ...
