Description

Technical Field

[0001] This utility model relates to the technical field of gas alarm controllers, and in particular to a gas alarm controller with a blocking function. Background Technology

[0002] A gas alarm controller with a blocking function is a highly efficient safety protection device designed to monitor the concentration of combustible or toxic gases in the environment and automatically cut off the connection with potential hazard sources (such as gas systems) when the concentration of dangerous gases exceeds the standard, thereby preventing further gas leakage and effectively reducing the risk of accidents.

[0003] In the prior art, patent application number 202011551998.6 discloses a gas alarm controller with a blocking function, including a housing and a gas alarm controller. The gas alarm controller is fixedly installed on one side of the housing. A water tank is fixedly connected to the bottom side of the housing. A circulating water pipe is fixedly connected to the outlet of the water tank. A water pump is installed on the circulating water pipe. A cover plate is connected to one side of the housing via a hinge. Two circular holes are opened on the side of the cover plate. A connecting bracket is fixedly connected to each of the two circular holes. A rotating shaft is rotatably connected to each of the two connecting brackets. A fan is fixedly connected to one end of each of the two rotating shafts.

[0004] During use, it was found that the above device required the cover to be opened and closed repeatedly when adjusting the parameters of the gas alarm controller, which affected the efficiency of parameter adjustment and made it less convenient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gas alarm controller with a blocking function that improves the convenience of parameter adjustment.

[0006] This utility model discloses a gas alarm controller with a blocking function, comprising a housing, a gas alarm controller body, and a control panel. The gas alarm controller body is installed inside the housing, which also includes a cover assembly, an anti-touch assembly, and a filter assembly. A set of air inlets is provided at each of the left and right ends of the housing, and a filter assembly is installed on each air inlet. The cover assembly is fixedly installed at the front end of the housing, and the control panel is mounted on the cover assembly. An anti-touch assembly is movably installed on the cover assembly, sealing the control panel. The gas alarm controller body is wiredly connected to the control panel. In use, the cover assembly seals the front end of the housing, and the anti-touch assembly prevents external objects from touching the control panel. When the parameters of the housing need to be adjusted, the operator releases the seal of the anti-touch assembly on the control panel and then adjusts the detection parameters of the gas alarm controller body through the control panel. When the control panel detects smoke, it issues an alarm and simultaneously closes the solenoid valve electrically connected to the control panel, thereby preventing further gas leakage and improving convenience.

[0007] Preferably, the lid assembly includes a lid body, bolts, and positioning rods. A set of threaded grooves is provided at each of the four corners of the front end of the lid body, and a set of bolts is provided at each of the four corners of the lid body. A positioning rod is provided at the rear end of the lid body, and a positioning groove is provided at the front end of the lid body. The control panel is embedded and installed at the front end of the lid body. In use, the positioning rod is inserted into the positioning groove to complete the positioning of the lid body. Then, the bolts pass through the lid body and are threadedly connected to the corresponding threaded grooves, thereby sealing the front end of the lid body.

[0008] Preferably, the anti-touch component includes a sealing plate, a pivot pin, a fixing plate, a groove, a light bar, a spring, a lifting plate, and insert rods. The sealing plate is hinged to the front end of the cover body via the pivot pin. Two sets of fixing plates are provided at the front end of the cover body, each set having a set of insertion holes. A groove is provided at the front end of the cover body, and a light bar is fixedly installed in the groove. The lifting plate is slidably connected to the light bar. A set of springs is fitted onto the outer side of each set of light bars. Two sets of insert rods are provided at the top of the lifting plate. Under normal conditions, the sealing plate seals the front end of the control panel while the lifting plate, under the elastic force of the spring, drives the insert rods to insert into the insertion holes of the fixing plate. When it is necessary to adjust the parameters of the gas alarm controller body, the operator moves the lifting plate downwards, causing the insert rods to separate from the insertion holes. Then, the sealing plate, with the support of the pivot pin, releases the seal on the front end of the control panel. The operator can then adjust the detection parameters of the gas alarm controller body through the control panel, improving protection.

[0009] Preferably, the filter assembly includes a fixed frame and a filter screen. A fixed frame is installed in each set of air inlets, and a filter screen is installed inside each set of fixed frames. The flue gas passes through the filter screen and enters the chamber, where it is detected by the gas alarm controller. The filter screen prevents external particles from entering the chamber.

[0010] Preferably, it also includes annular flat washers, with a set of annular flat washers fitted on the outside of each set of bolts; the bolts increase the contact area with the body of the box cover through the annular flat washers, thereby improving the connection firmness.

[0011] Preferably, it also includes a lever, with a lever provided at the front end of the lifting plate; the operator can move the lifting plate by using the lever, improving convenience.

[0012] Preferably, it also includes an observation window, wherein the sealing plate is provided with an observation port, and the observation window is installed on the observation port.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the cover assembly seals the front end of the box, and the anti-touch assembly prevents foreign objects from touching the control panel. When it is necessary to adjust the parameters of the box, the operator releases the anti-touch assembly from the control panel and then adjusts the detection parameters of the gas alarm controller through the control panel. When the control panel detects smoke, it issues an alarm and closes the solenoid valve electrically connected to the control panel, thereby preventing further gas leakage and improving convenience.
