The invention aims to realize the alarm protection structure of the main board of the gas detector by the following technical scheme, wherein: the gas detector comprises a power supply unit, a display unit, a dust alarm unit, a temperature and humidity alarm unit and an acousto-optic alarm control unit, wherein the power supply unit, the display unit, the temperature and humidity alarm unit, the dust alarm unit and the acousto-optic alarm control unit are all connected with a gas detector mainboard, the dust alarm unit comprises a dust filtering alarm device, the temperature and humidity alarm unit comprises a temperature sensor and a humidity sensor, the dust filtering alarm device comprises a main board box 1 and a main board frame 2, the main board frame 2 is arranged in the main board box 1, the main board frame 2 is used for fixing a gas detector mainboard 3, the temperature sensor 4 and the humidity sensor 5 are arranged in the main board box 1, a heat dissipation cover 6 is arranged above the main board box 1, vent holes 601 are uniformly distributed on the heat dissipation cover 6, and a dust filtering shaft 7 is fixed below the vent holes 601, the dust filtering shaft 7 is of a vertically communicated cylindrical structure, two layers of steps 701 are arranged on the outer side of the dust filtering shaft 7, rotating rings 702 are uniformly arranged on the steps 701, each rotating ring 702 is connected with a supporting rod 703, sealing cloth 704 is connected between the supporting rods 703, the supporting rods 703 can be vertically scattered or closed around the rotating rings 702, elastic clamping buttons 8 are arranged on the outer sides of the supporting rods 703, an alarm filtering cylinder 9 is arranged outside the dust filtering shaft 7, a touch sensor 901 is installed at the bottom of the alarm filtering cylinder 9, induction receivers 902 corresponding to the touch sensor 901 are arranged below the alarm filtering cylinder 9, and the induction receivers 902 are connected with the main board 3.
Specifically, the sound-light alarm control unit comprises an LED flashing light and a buzzer.
Specifically, the alarm filter cartridge 9 is a cylindrical structure with an open upper end, the alarm filter cartridge 9 is provided with chutes 903, the number of which is the same as that of the support rods 703, the chutes 903 are matched with the elastic clamping buttons 8, the cylindrical wall of the alarm filter cartridge 9 is uniformly provided with filter air holes 904, and the filter air holes 904 are all provided with filter screens.
Specifically, the elastic clamping button 8 includes a pushing block 801, a spring groove 802 is disposed on the outermost side of the supporting rod 703, a spring 803 is disposed inside the spring groove 802, and the pushing block 801 is matched with the spring groove 802, so that the pushing block 801 can slide left and right in the spring groove 802.
The working principle is as follows: when the gas detector works, the main board 3 supplies power through the power supply unit, the main board 3 controls the temperature sensor 4 and the humidity sensor 5 to start working and feeds data back to the main board 3 in time, meanwhile, the air is filled into the dust filtering shaft 7 through the air vent 601 by the compressor, at this time, the support rod 703 outside the dust filtering shaft 7 is dispersed downward around the rotating ring 702, meanwhile, the sealing cloth 704 is driven to open, at the moment, under the action of the elastic clamping button 8, the alarm filter cylinder 9 is hung on the support rod 703 through the elastic clamping button 8, the sealing cloth 704 and the support rod 703 divide the alarm filter cylinder 9 into a plurality of independent closed spaces, at the moment, air is filled into the closed space at the bottommost layer through the dust filter shaft 7, because the alarm filter cartridge 9 is provided with the filter air holes 904 and the filter screen, dust in the air is collected in the space of the lowest layer.
When the time goes on, the space at the lowest layer is gradually filled with the filtered dust, and the filtering air holes 904 are also gradually blocked, then the pressure of the space at the lower layer is gradually increased because the air is continuously charged and can not be completely discharged, after the pressure is gradually increased, the pressure of the space at the lower layer enables the space between the alarm filter cartridge and the support rod to be increased, at the moment, the alarm filter cartridge 9 tends to move downwards, the elastic clamping button 8 on the support rod 703 moves inwards under the action of the alarm filter cartridge 9, after the elastic clamping button moves to a certain distance, at the moment, because the alarm filter cartridge 9 is not supported by the support rod 703, the alarm filter cartridge 9 moves downwards, after the alarm filter cartridge 9 moves downwards, the non-working filtering air holes 904 and the filtering net at the upper layer are leaked, at the moment, the air leaks from the new filtering air holes 904 and the filtering net, the inside atmospheric pressure of lower floor is alleviated this moment, then alarm filter cartridge 9 stops under the effect of elasticity card button 8 to move down, after alarm filter cartridge 9 is removing the certain distance, the touching inductor 901 that is located alarm filter cartridge 9 bottom contacts with response receiver 902, transmit alarm signal to mainboard 3 this moment, mainboard 3 control LED flashing light and buzzer work, report to the police through the display element simultaneously and show, this device can guarantee that the inside air cycle of mainboard incasement keeps certain intensity, can not cause the decay because of the jam of dust.
When the staff solved corresponding problem through alarm signal, only need take off whole cooling cover this moment, carry out 180 upsets with warning cartridge filter 9 and dust filter axle 7 together, because the influence of gravity, the bracing piece shrink, warning cartridge filter 9 does not receive the influence of bracing piece this moment, can take off the dust of clearance inside easily, later rotate 180 again, embolia each corresponding dust filter axle 7 by supreme down with warning cartridge filter 9 again, make warning cartridge filter 9 pass through the elasticity snap-button card in the highest position, pack the cooling cover into the mainboard case again this moment, can continue to circulate work, convenient and fast when this method carries out dust disposal.
According to the invention, the compressor is used for circularly replacing the gas in the mainboard chamber, and the dust alarming and filtering device is arranged, so that dust particles in the air are filtered while the mainboard chamber is subjected to gas circulation heat dissipation, so that the mainboard in the mainboard chamber is free from dust pollution, meanwhile, the novel dust alarming and filtering device realizes the alarming device for blocking the filtering hole due to excessive dust collection, the subsequent reduction of filtering and heat dissipation effects is prevented, and the gas detector in a severe environment can be ensured to normally work.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
