A data acquisition device for fire alarm control includes an alarm control device 1. A fixed seat 2 is fixed on the outside of the alarm control device 1. A data collector 3 is inserted on the fixed seat 2. A smoke collector 4 is arranged on one side of the data collector 3. An explosion-proof frame 5 is fixed on the outside of the alarm control device 1. A translation plate 6 is arranged on one side of the fixed seat 2. A temperature collection head 7 and a combustible gas detector 8 are respectively arranged on the side of the translation plate 6 away from the fixed seat 2. An adjustment mechanism is arranged on one side of the fixed seat 2, and the adjustment mechanism is used for the front and back movement of the translation plate 6; the adjustment mechanism includes two adjustment plates 201, and the two adjustment plates 201 are connected by a rotating shaft 202. Two first cross plates 203 distributed symmetrically up and down are fixed on one side of the fixed seat 2. Two first sliding rods 204 are fixed in the middle of the two first cross plates 203. Two first sliders 205 are slidably connected to the outside of the first sliding rods 204. Two second cross plates 601 distributed symmetrically up and down are fixed on one side of the translation plate 6. A second sliding rod 602 is fixed in the middle of the two second cross plates 601. Two second sliders 603 are slidably connected to the outside of the second sliding rod 602. Two first movable shafts 206 are arranged on the adjustment plate 201, and the two first movable shafts 206 extend out of both ends of the adjustment plate 201 and are respectively fixed to the outside of the first slider 205 and the outside of the second slider 603. A cylinder 207 is fixed on the outside of the first cross plate 203, and the ejector rod of the cylinder 207 penetrates through the first cross plate 203 and is fixed to one side of the first slider 205; a top plate 501 is arranged on the top of the explosion-proof frame 5, and an explosion-proof plate 502 is fixedly connected to the bottom of the top plate 501. The bottom end of the explosion-proof plate 502 is inserted into the slot 503 opened in the explosion-proof frame 5, and a through hole 504 is opened inside the explosion-proof plate 502.

[0028] Through the above technical solution, when there is no fire, the top plate 501 is placed on the top of the explosion-proof frame 5, so that the bottom end of the explosion-proof plate 502 at the bottom of the explosion-proof frame 5 is inserted into the slot 503. The ejector rod of the cylinder 207 drives the two first sliders 205 to slide on the first slide rod 204, so that the two first sliders 205 approach each other.

The temperature collection head 7, the combustible gas detector 8 and the smoke collector 4 perform normal data collection in the explosion-proof frame 5, and the collected data is transmitted to the alarm control device 1 for effective analysis to make the best rescue plan.

[0029] Refer to Figure 1 、 Figure 3 and Figure 7 As shown in FIGS.

[0030] Refer to Figure 6 and Figure 7 As shown in FIGS.

[0031] Refer to Figure 1 and Figure 5, two symmetrically arranged fixing plates 509 are fixed to the bottom of the top plate 501. The fixing plates 509 are inserted into the fixing grooves 510 formed in the explosion-proof frame 5. When the top plate 501 is placed on the top of the explosion-proof frame 5, the fixing plates 509 at its bottom are inserted into the fixing grooves 510. Through the cooperation of the fixing plates 509 and the fixing grooves 510, it is prevented that the top plate 501 moves randomly on the top of the explosion-proof frame 5.

[0032] Refer to Figure 1 , Figure 2 and Figure 5 , a groove 511 is formed on one side of the fixing plate 509. A spring 512 is fixed to the inner side wall of the groove 511. One end of each spring 512 is fixedly connected to a pressing plate 513. A limiting plate 514 is fixedly connected to the side of the pressing plate 513 away from the spring 512. The end of the limiting plate 514 extending out of the groove 511 is inserted into the limiting hole 515 formed in the explosion-proof frame 5. After the fixing plate 509 is inserted into the fixing groove 510, one end of the limiting plate 514 in the groove 511 is inserted into the limiting hole 515 under the elastic action of the spring 512. Through the cooperation of the limiting plate 514 and the limiting hole 515, the fixing plate 509 is more firmly and reliably inserted into the fixing groove 510.

[0033] Refer to Figure 2 , a baffle 516 is sleeved inside the groove 511 and outside the limiting plate 514. The outer side of the baffle 516 is fixedly connected to the inner wall of the groove 511. The baffle 516 limits the movement of the pressing plate 513 to prevent the pressing plate 513 from moving outside the groove 511 under the elastic action of the spring 512.

[0034] Refer to Figure 5 , an air inlet hole 517 is formed on one side of the explosion-proof frame 5. A dust-proof cylinder 518 is inserted into the air inlet hole 517. A dust-proof net 519 is fixedly connected inside the dust-proof cylinder 518.

Smoke enters the explosion-proof frame 5 through the air inlet hole 517, enabling the smoke collector 4 to collect data on one side of the data collector 3. And by inserting the dust-proof cylinder 518 into the air inlet hole 517, the smoke is filtered by the dust-proof net 519 in the dust-proof cylinder 518 to prevent impurities in the smoke from entering the explosion-proof frame 5.

[0035] Refer to Figure 5 , a fixing bolt 521 is arranged on one side of the fixing ring 520. One end of the fixing bolt 521 penetrates through the fixing ring 520 and is screwed into the threaded groove 522 formed on one side of the explosion-proof frame 5. By penetrating one end of the fixing bolt 521 through the fixing ring 520 and screwing it into the threaded groove 522, the fixing ring 520 can be fixed to the explosion-proof frame 5 through the cooperation of the fixing bolt 521 and the threaded groove 522, and further the dust-proof cylinder 518 is fixed in the air inlet hole 517 to prevent the dust-proof cylinder 518 from falling off from the inside of the air inlet hole 517.

[0036] The implementation principle of a data acquisition device for fire alarm control in an embodiment of the present utility model is as follows: By adopting an adjustment mechanism, when a fire does not occur, the top plate 501 is placed on the explosion-proof frame 5, and the bottom end of the explosion-proof plate 502 at the bottom of the explosion-proof frame 5 is inserted into the slot 503. The ejector rod of the cylinder 207 drives two first sliders 205 to slide on the first slide rod 204, so that the two first sliders 205 approach each other. Through the movement of the two first sliders 205, the two adjusting plates 201 rotate, and through the cooperation of the second slide rod 602 and the second slider 603, the other end of the adjusting plate 201 moves normally. Through the rotation of the two adjusting plates 201, the translation plate 6 can be driven to move forward, so that the translation plate 6 drives the temperature collection head 7 and the combustible gas detector 8 to move through the through hole 504 to the outside of the explosion-proof plate 502, so that the temperature collection head 7 and the combustible gas detector 8 perform data acquisition. When a fire occurs, the two adjusting plates 201 are reset, so that the temperature collection head 7 and the combustible gas detector 8 move backward into the explosion-proof frame 5. Through the cooperation of the explosion-proof frame 5 and the explosion-proof plate 502, it effectively prevents the temperature collection head 7 and the combustible gas detector 8 from being easily affected by the impact force, thereby preventing the temperature collection head 7 and the combustible gas detector 8 from being damaged. The temperature collection head 7, the combustible gas detector 8 and the smoke collector 4 perform normal data acquisition in the explosion-proof frame 5, and the collected data is transmitted to the alarm control device 1 for effective analysis to make the best rescue plan.
