[0028] Embodiment 1

[0029] A gas fire extinguishing controller, such as Figure 1-Figure 2As shown, it includes a gas fire extinguishing controller 1, a main air duct 2 is fixedly installed on the side wall of the gas fire extinguishing controller 1, the main air duct 2 is a rectangular frame, the interior of the main air duct 2 is hollow to form an air duct 3, the lower end of the main air duct 2 is provided with a lower air port 4 communicating with the air duct 3, the middle of the left and right sides of the main air duct 2 are provided with a side air port 5 communicating with the air duct 3, the top surface of the main air duct 2 is provided with an upper air port 6 communicating with the air duct 3, at least one set of fans 7 is fixedly installed inside the air duct 3, driven by the fans 7, the air flow in the air duct 3 flows to form an air ring with a head-to-tail circulation, and the air in the main air duct 2 is A smoke sensor 8 and a temperature sensor 9 are fixedly installed below the upper air outlet 6. The smoke sensor 8 and the temperature sensor 9 are electrically connected to the gas fire extinguishing controller 1. The downwind outlets 4 and the side air outlets 5 opened on the surrounding areas of the main air duct 2 can quickly collect the gas near the gas fire extinguishing controller 1 through the smoke sensor 8 and the temperature sensor 9. When it is detected that the temperature of the air flow entering the air duct 3 from the outside or the smoke contained in it meets the fire data, the alarm system of the gas fire extinguishing controller 1 is triggered at the first time to quickly extinguish the fire occurring near the gas fire extinguishing controller 1.

[0030] Furthermore, a baffle 10 is fixedly installed at a position downstream of the air ring of the upper air outlet 6 in the air duct 3. The baffle 10 is sealed in the air duct 3 to interrupt the internal circulation of the air ring in the air duct 3, so that the airflow in the air duct 3 is discharged from the upper air outlet 6, and the external airflow can enter the air duct 3 from the lower air outlet 4 and the side air outlet 5.

[0031] In particular, the fans 7 are arranged in the downstream direction of the downwind outlet 4 and the side outlet 5, and the output direction is the same as the air ring flow direction.

[0032] In this embodiment, an air duct 3 surrounding the gas fire extinguishing controller 1 and a fan 7 in the air duct 3 are used to allow external air flow to enter the air duct 3 from the downwind port 4 and the side wind port 5. After detection by the smoke sensor 8 and the temperature sensor 9, it is determined immediately whether a fire occurs around the gas fire extinguishing controller 1, thereby expanding the sampling range.

[0033] Embodiment 2

[0034] A gas fire extinguishing controller 1, such as Figure 3 As shown, the difference between this embodiment and the first embodiment is that the temperature sensor 9 is fixedly installed above the downwind outlet 4, and fans 7 are fixedly installed at positions on both sides of the air duct 3 corresponding to the downwind outlet 4, and the output ends of the two groups of fans 7 there are far away from each other, so that two groups of air rings are formed in the air duct 3 on the left and right, and the two groups of air rings are in opposite directions, and finally flow out from the upwind outlet 6, further increasing the accuracy of gas sampling around the gas fire extinguishing controller 1, and avoiding the defects of the air ring being too long and escaping in the middle in the first embodiment.

[0035] Furthermore, in order to reduce the entry of dust or large particles into the air duct 3, a dust shield 11 is fixedly installed in the side air outlet 5. The dust shield 11 is composed of a plurality of downwardly inclined rectangular pieces, which can block the debris without affecting the entry of smoke into the air duct 3.

[0036] In this embodiment, by changing the position and direction of the fan 7, two air rings in opposite directions are formed in the air duct 3, the length of the air ring is reduced, and the gas entering the air duct 3 is prevented from escaping midway. The position of the temperature sensor 9 is changed to below the gas fire extinguishing controller 1, so that the smoke sensor 8 and the temperature sensor 9 are dispersed for easy maintenance.

[0037] Embodiment 3

[0038] A gas fire extinguishing controller 1, such as Figure 4 As shown, the difference between this embodiment and the second embodiment is that an air intake duct 12 is fixedly installed at the position of the main air duct 2 corresponding to the side air outlet 5, the air intake duct 12 is hollow and communicated with the air duct 3, and a fan 7 with its output end facing the air duct 3 is fixedly installed in the air intake duct 12, thereby further reducing the possibility of gas escape.

[0039] Furthermore, the entrance of the air intake duct 12 is tilted downward to form an air intake port 13. When a fire occurs and fire water is sprayed in to extinguish the fire, the probability of water flowing into the air duct 3 is reduced. A dust shield 11 can also be installed to reduce the entry of debris into the air duct 3. Correspondingly, a water shield cap 14 covering the upper air outlet 6 is fixedly installed at the position of the main air duct 2 corresponding to the upper air outlet 6, which is also used to reduce the entry of dust and water into the air duct 3.

[0040] Furthermore, a cleaning port 15 is provided on the side wall of the main air duct 2 at a position corresponding to the top of the air duct 3, and a cleaning plate 16 is movably installed in the cleaning port 15. A handle 17 is provided at one end of the cleaning plate 16 and a sweeping head 18 is provided at the other end. Brushes are provided on the upper and lower end surfaces of the cleaning plate 16. By holding the handle 17 and inserting the cleaning plate 16 into the cleaning port 15, the inner wall surface of the main air duct 2 is cleaned, and the sweeping head 18 can clean the gaps on both sides of the temperature sensor 9.

[0041] Furthermore, ash outlets 19 are provided on both sides of the bottom end surface of the main air duct 2, and plugs 20 are installed in the ash outlets 19 for interference fit. When the main air duct 2 is cleaned, the plugs 20 are pulled out of the ash outlets 19, and the dust collected by the cleaning plate 16 during cleaning can be discharged from the ash outlets 19.

[0042] In the embodiment, the air intake duct 12 and the water retaining cap 14 are installed at the side air outlet 5 and the upper air outlet 6 to reduce the probability of water flowing into the air duct 3 when a fire occurs, and the interior of the air duct 3 is cleaned and maintained by the cleaning plate 16.

[0043] The working principle of the utility model is as follows: by utilizing the air duct 3 which surrounds the gas fire extinguishing controller 1 and the fan 7 in the air duct 3, the external air flow enters the air duct 3 from the downwind port 4 and the side wind port 5, thereby expanding the sampling range, and through the detection of the smoke sensor 8 and the temperature sensor 9, it is immediately determined whether a fire occurs around the gas fire extinguishing controller 1, thereby quickly carrying out a fire fighting response, and avoiding the special situation in which a fire occurs around the gas fire extinguishing controller 1 and the gas fire extinguishing controller 1 is damaged first.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
