Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
As shown in fig. 1-2, the toxic gas monitoring and alarming device for the underground pipe gallery comprises a fixing plate which is installed on the wall of the underground pipe gallery through screws, a fixing rod which extends towards one side is installed on the fixing plate, a limiting rod which is perpendicular to the bottom of the underground pipe gallery is fixed at the end part of the fixing rod, a limiting sleeve which ascends and descends along with the ascending and descending of the water level in the underground pipe gallery is sleeved outside the limiting rod, a monitoring floating plate which extends towards one side is installed on the outer wall of the limiting sleeve, a gas monitoring assembly is installed on the monitoring floating plate, and an alarm which is connected with the gas monitoring assembly is installed at the top end of the fixing rod;
wherein, gas monitoring subassembly is connected with microprocessor including installing a plurality of gas sensor on monitoring kickboard surface, a plurality of gas sensor, and microprocessor still is connected with the alarm, the work of control alarm, and after the gas data that gas sensor detected turned into the digital quantity signal through AD conversion module, the transmission was handled for microprocessor, comes the alarm work according to gas data.
On foretell basis, equipment passes through the fixed plate to be installed on the wall in the underground pipe gallery, and the mode that adopts the screw is fixed the fixed plate, then overlaps the stop collar in the outside of gag lever post, installs the alarm on the top of gag lever post again, utilizes the gas monitoring subassembly on the monitoring kickboard to detect the gas in the underground pipe gallery.
Simultaneously, the monitoring kickboard still can go up and down according to the lift of water level in the piping lane, prevents that gas monitoring subassembly from soaking in the water.
Furthermore, the limiting rod is arranged in a regular quadrangular prism shape, the inner wall of the limiting sleeve is attached to the outer wall of the limiting rod, a slot extending from the top end to the bottom end is formed in the outer wall of the limiting sleeve, and the fixing rod is fixedly connected with the limiting rod from the slot;
because the gag lever post is the prism form, at the in-process that stop collar and monitoring kickboard go up and down, the monitoring kickboard can not rotate in the gag lever post outside, and sets up the fluting in the stop collar outside, makes the dead lever be connected with the gag lever post from the fluting for the stop collar can not produce the conflict between with the dead lever in-process that goes up and down, can not influence the normal work and the use of equipment.
The monitoring floating plate is vertically fixed on the outer wall of the limiting sleeve, and a foam plate is arranged at the bottom of the monitoring floating plate;
when the water level changes in the underground pipe gallery, the buoyancy that the cystosepiment produced can promote the monitoring kickboard and go up and down, avoids the gas monitoring subassembly to receive and soaks.
A protective outer cover fixed on the monitoring floating plate is sleeved outside the gas sensor, and the detection end of the gas sensor penetrates through the protective outer cover and extends to the surface of the protective outer cover;
wherein, except the monitoring kickboard that adopts the lift, there is the protection dustcoat to protect it outside gas sensor, avoids steam and debris to cause the destruction to the sensor.
A circle of water absorption cotton plate is arranged around the outer side of the protective outer cover, and the water absorption cotton plate is vertically arranged on the surface of the monitoring floating plate;
in order to prevent that the water body from flowing and the splash in the process of billowing are impregnated on the monitoring kickboard, utilize the cotton board of waterproof to adsorb the splash, further promote the security of gas sensor in the course of the work.
On the basis, the utility model discloses in the use, its gas monitoring subassembly part is located the bottom in the underground pipe gallery all the time, and is floating, makes things convenient for its use in the underground pipe gallery that has ponding promptly, makes it to detect the poisonous gas of deposit in the pipe gallery bottom simultaneously, can not influence its detection precision, has improved the practicality.
