Detailed Description
The utility model will be further described with reference to specific embodiments, and the advantages and features of the utility model will become apparent as the description proceeds. These examples are illustrative only and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model, and that such changes and modifications may be made without departing from the spirit and scope of the utility model.
Referring to fig. 1 and 2, the utility model relates to a combustible gas detection control device for a pipeline, which comprises a gas concentration sensor 1, a control panel 2, a driving motor 3, a reset switch 4, an opening and closing mechanism 5 and a positioning sensor 6, wherein the opening and closing mechanism 5 is installed on the pipeline, the opening and closing mechanism 5 is controlled by the driving motor 3, and the gas concentration sensor 1, the positioning sensor 6, the driving motor 3 and the reset switch 5 are all connected to the control panel 2; when the opening and closing mechanism 5 is in a state of closing the pipeline, the fan-shaped tooth block of the opening and closing mechanism 5 is in contact with the iron sheet of the positioning sensor 6, the iron sheet of the positioning sensor 6 triggers the reset switch 5, and after the control panel 5 receives a signal of the reset switch 5, the driving motor is controlled to stop running; the starting and stopping mechanism comprises a shell 10, and a driving gear 7, a transmission gear 8 and a fan-shaped tooth block 9 which are arranged in the shell 10, wherein the driving gear 7 is arranged on a motor shaft of the driving motor 3, the fan-shaped tooth block 9 is rotatably arranged on the shell through a rotating shaft, one end of the rotating shaft 9 is provided with the fan-shaped tooth block 9, and the other end of the rotating shaft extends into a pipeline and is provided with a valve plate; the transmission gear 8 is also arranged between the sector gear block 9 and the driving gear 7, and the transmission gear 8 is meshed with the driving gear 7 and the sector gear block 9.
The mounting hole of driving gear 7 be the bar hole, this driving motor 3's motor shaft is put into in this bar hole, with driving gear 7 fixed connection together, improved the fastness of connection of motor shaft and driving gear.
The working principle of the utility model is as follows: when gas concentration sensor detects that gas concentration exceeds standard, send signal to control panel, control panel control driving motor drives the driving gear and rotates, the driving gear passes through the fan-shaped tooth piece of driving gear drive and takes place to rotate, and then it is rotatory (rotatory 90 °) to drive the valve plate, seal the pipeline, when fan-shaped tooth piece rotates to the state of closing the pipeline completely, fan-shaped tooth piece contacts with the iron sheet of location inductor, reset switch is triggered to location sensor's iron sheet, after control panel received reset switch's signal, control driving motor stall. The two positioning sensors are distributed on two sides of the fan-shaped tooth block and are in movable fit with the fan-shaped tooth block.
