Description

Technical Field

[0001] This utility model relates to the field of gas sensing and detection technology, and in particular to an R290 explosion-proof and flame-retardant monitoring device. Background Technology

[0002] With industrial development, the widespread use of fluorinated refrigerants has brought serious environmental and health problems. The chlorine and fluorine they contain can damage the ozone layer, exacerbate climate change, and even damage the nervous system and cause death. R290 refrigerant, on the other hand, has an extremely low global warming potential (GWP) and an ODP value of 0. It does not damage the ozone layer and does not produce a greenhouse effect, so it has been vigorously promoted and is expected to become the mainstream refrigerant in the market. However, R290 refrigerant is a highly flammable substance. During use, if there is a leak in the valves or pipelines of the air conditioner, the R290 leak may cause an explosion when it comes into contact with an open flame or an electric spark. This could affect production at best, and endanger life and property at worst. Therefore, it is necessary to design it accordingly.

[0003] To this end, patent CN215640743U discloses an explosion-proof online dust concentration monitoring device, which relates to the technical field of online dust concentration monitoring devices. The key points of its technical solution are: it includes a flange, a base is fixedly installed on the top of the flange, a fixed seat is connected to the top of the base by a hinge, a fixed rod is connected inside the fixed seat, two symmetrically arranged placement rods are fixedly installed inside the fixed rod, an explosion-proof net is movably connected to the top of the placement rod, the explosion-proof net is coated with a waterproof and breathable layer, the waterproof and breathable layer is coated with a flame-retardant layer, the bottom of the explosion-proof net is coated with a heat insulation layer, the explosion-proof net is sleeved on the outside of the signal transmitter and the signal receiver, and flame-retardant layer, waterproof and breathable layer and heat insulation layer are respectively provided on the outside and inside of the explosion-proof net, so as to prevent fire from damaging the signal transmitter and the signal receiver when the equipment catches fire, thereby increasing the service life of the signal transmitter and the signal receiver;

[0004] Although the aforementioned explosion-proof smoke and dust concentration online monitoring device can prevent fire from damaging the signal transmitter and receiver during use, it is inconvenient to readjust the position of the monitoring device after installation. Therefore, it is necessary to design an R290 explosion-proof and flame-retardant monitoring device. Utility Model Content

[0005] The purpose of this invention is to provide an R290 explosion-proof and flame-retardant monitoring device to solve the defect of existing R290 explosion-proof and flame-retardant monitoring devices that are inconvenient to readjust after installation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an R290 explosion-proof and flame-retardant monitoring device, including a mounting base;

[0007] An adjustment structure is provided on one side inside the mounting base. The adjustment structure includes an adjustment groove starting from one side inside the mounting base. An adjustment block is provided inside the adjustment groove. A lead screw is threadedly connected inside the adjustment block.

[0008] A monitoring structure is fixed to one side of the regulating block, a sensor is fixed to the inner wall of the bottom of the monitoring structure, and an air intake tube is fixed to the bottom of the monitoring structure.

[0009] Furthermore, a protective component is fixed on the outer wall of the mounting base, and mounting brackets are evenly fixed on the outer wall of the mounting base on the side away from the protective component.

[0010] Furthermore, one end of the rotating shaft near the first bevel gear extends to the outside of the mounting plate and is fixed with a second bevel gear, while the other end of the rotating shaft extends to the outside of the mounting plate and is fixed with a handle.

[0011] Furthermore, the top end of the lead screw extends into the interior of the mounting base and is rotatably connected to the mounting base, and the first bevel gear and the second bevel gear mesh with each other.

[0012] Furthermore, the protective assembly includes an explosion-proof box, an explosion-proof door, and a flame retardant. The explosion-proof box is fixed to the outer wall of the mounting base, and an explosion-proof door is hinged to one side of the explosion-proof box. Flame retardants are provided on the outer sides of both the explosion-proof box and the explosion-proof door.

[0013] Furthermore, the monitoring structure includes a door panel, a monitoring box, an alarm bell, a circuit board, a data processor, a microcontroller, and a data storage device.

[0017] The R290 explosion-proof and flame-retardant monitoring device provided by this utility model has the following advantages:

[0018] With the adjustment structure, the adjustment block and the lead screw are connected by a threaded connection. By rotating the handle, the adjustment block can be moved up and down inside the adjustment groove. The movement of the adjustment block will cause the monitoring structure to move up and down, thus adjusting the position of the monitoring structure. When the monitoring structure moves, it will cause the sensor to move up and down, which is convenient for monitoring the environment at different heights. This makes the device easy to move the position of the monitoring structure and improves the convenience of using the R290 explosion-proof and flame-retardant monitoring device.

[0019] By incorporating protective components, the monitoring structure can be protected by the explosion-proof enclosure and explosion-proof doors, preventing damage from external explosions. The flame-retardant effect of the flame retardant agent can also prevent the explosion-proof enclosure and explosion-proof doors from being damaged by fire, thus realizing the explosion-proof and flame-retardant function of the device and improving the safety of the R290 explosion-proof and flame-retardant monitoring device during use.

[0020] By incorporating a monitoring structure, the sensor monitors the gas in the environment through an air intake tube, detecting whether the air contains leaked R290 gas. Under the control of a microcontroller, the sensor can transmit abnormal signals to an alarm bell, which can promptly sound an alarm to remind staff to handle the situation. This enables the device to have convenient detection and alarm functions, improving the convenience and efficiency of the R290 explosion-proof and flame-retardant monitoring device during use.
