DETAILED DESCRIPTION

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference Figure 1-4, a combustible gas detector with anti-interference, a combustible gas detector with anti-interference, comprising a first protective plate 1, a second protective plate 2, a detector body 4 and a display panel 5, a display panel 5 is arranged on the side of the detector body 4 close to the first protective plate 1, wiring heads 6 and alarm components 21 are arranged on both sides of the detector body 4, a second protective plate 2 that cooperates with it is arranged on the back of the first protective plate 1, cavities 3 are symmetrically opened in the first protective plate 1 and the second protective plate 2, the detector body 4 is sleeved in the cavity 3, a second slide groove 10 is opened inside the side of the second protective plate 2 away from the detector body 4, a rubber plate 11 is slidably inserted in the second slide groove 10, a second spring 12 is fixed between the side of the rubber plate 11 away from the detector body 4 and the side wall of the second slide groove 10, a lower connecting pipe 13 that penetrates the outer surface of the first protective plate 1 is fixedly connected to the bottom surface of the detector body 4, and a filter component is arranged at the bottom of the lower connecting pipe 13.

[0024] Specifically, a first slide groove 7 is provided inside the first protective plate 1 on a side away from the detector body 4, a rubber ring 8 is slidably inserted in the first slide groove 7, and a plurality of first springs 9 are fixed between the side of the rubber ring 8 away from the detector body 4 and the side wall of the first slide groove 7. Through the cooperation of the first spring 9 and the rubber ring 8, the detector can absorb part of the kinetic energy through the rubber ring 8 when it is hit, thereby protecting the internal components. Rubber pads that cooperate with the outer surface of the terminal 6 and the alarm component 21 are provided at both ends of the opposite surfaces of the first protective plate 1 and the second protective plate 2. The rubber pads can better protect the internal components from being damaged due to impact. The filter component includes a first sleeve 14, a connecting tube 15 and a water-absorbing resin 16, and a lower connecting pipe 13. A first sleeve 14 is fixedly connected to the end away from the detector body 4, and a connecting tube 15 is threadedly connected to the end of the first sleeve 14 away from the lower connecting tube 13. The threaded connection makes it easier to remove the connecting tube 15 from the water-absorbing resin 16, so as to facilitate the replacement of the internal water-absorbing resin 16. The water-absorbing resin 16 is engaged with the connecting tube 15 and the first sleeve 14 at the connection. The water-absorbing resin 16 can be used to prevent water vapor from entering and affecting the detection results. A second sleeve 17 is threadedly connected to the end of the connecting tube 15 away from the first sleeve 14, so that the second sleeve 17 is easier to disassemble and separate from the connecting tube 15. A dustproof net 18 is engaged with the second sleeve 17 at the connection with the connecting tube 15 to prevent impurity particles in the gas to be measured from clogging the detector.

[0025] As an optimization solution, Figure 1-4As shown, an explosion-proof glass plate 19 is fixedly provided in the middle of the first protective plate 1 away from the end of the second protective plate 2, first fixing blocks 20 are symmetrically fixed at both ends of the sides of the first protective plate 1 and the second protective plate 2, fixing bolts 22 are inserted through the first fixing block 20, a second fixing block 23 is fixedly provided on the side of the second protective plate 2 away from the end of the first protective plate 1, and a sealing gasket 24 is fixedly provided between the opposite surfaces of the first protective plate 1 and the second protective plate 2.

[0026] Specifically, the display panel 5 is arranged at the center position of the outer surface of the detector body 4. The display panel 5 is located directly behind the explosion-proof glass plate 19 and is contained inside the explosion-proof glass plate 19, which avoids the display panel 5 being blocked by the explosion-proof glass plate 19, resulting in the staff being unable to view the complete data. The inner circle diameter of the first slide groove 7 and the rubber ring 8 is larger than the diameter of the explosion-proof glass plate 19, so that the first slide groove 7 and the rubber ring 8 will not block the line of sight of the explosion-proof glass plate 19 when working, and also avoids the impact on the explosion-proof glass plate 19.

[0027] Working principle: When the combustible gas detector is in use, the second protective plate 2 is fixed and placed by the expansion bolts and the second fixing block 23, and then the detector body 4 is snapped into the inside of the second protective plate 2, and the detector is connected to the external power supply through the wiring head 6. The combustible gas is absorbed and detected by the detector through the second sleeve 17, and displayed in real time on the display panel 5. Then the first protective plate 1 is put on the front side of the detector body 4 so that the explosion-proof glass plate 19 is aligned with the display panel 5, and the first fixing blocks 20 on both sides of the first protective plate 1 and the second protective plate 2 are fixed by bolts. The staff can view the data on the display panel 5 through the explosion-proof glass plate 19. When the combustible gas concentration reaches the set value, the alarm component 21 on the detector will sound to remind the staff so that the staff can take corresponding measures in time. When the combustible gas detector is hit during use, the external first protective plate 1 and the second protective plate 2 can prevent the internal detector body 4 from being directly damaged by the impact. At the same time, with the cooperation of the first spring 9 and the rubber ring 8, the rubber plate 11 and the second spring 12, the force on the internal circuit is reduced to avoid damage caused by impact. At the same time, through the cooperation of the first fixing block 20, the fixing bolt 22, and the sealing gasket 24, the inside of the detector is completely isolated from the outside world, avoiding corrosion to the inside of the detector and damage to the detector body 4 in a humid environment. At the same time, under the action of the water-absorbing resin 16 and the dust-proof net 18, the detector will not be blocked by water vapor and impurity particles in the gas to be measured, thereby causing the sensor component to be blocked. After the detector has been used for a period of time, when the internal water-absorbing resin 16 and the dust-proof net 18 need to be replaced, the connecting tube 15 and the second sleeve 17 can be screwed to replace the water-absorbing resin 16 and the dust-proof net 18 in time. When the internal components of the detector fail, the maintenance personnel screw the fixing bolts 22 to release the fixation of the first protective plate 1 and the second protective plate 2, and then open the first protective plate 1 to repair the detector body 4, making the maintenance more convenient.
