Description

Technical Field

[0001] This utility model relates to the field of natural gas boiler technology, specifically to an intelligent safety protection device for natural gas boilers. Background Technology

[0002] Gas-fired boilers include gas-fired hot water boilers, gas-fired hot water boilers, and gas-fired steam boilers. Gas-fired hot water boilers are also called gas-fired heating boilers and gas-fired bathing boilers. As the name suggests, gas-fired boilers are boilers that use gas as fuel. Compared with oil-fired boilers and electric boilers, gas-fired boilers are the most economical, so most people choose them for steam, heating, and bathing. To ensure the safe operation of gas-fired boilers, intelligent protection devices are needed to intelligently protect the boiler during operation, ensuring its safe and stable operation.

[0003] The existing protection devices lack a structure for ventilating the air around the boiler, which prevents leaked natural gas from dissipating in a timely manner during boiler operation, thus failing to effectively protect the boiler and increasing the risk of boiler operation. In addition, the existing safety protection devices cannot be adjusted according to the size of the boiler, making it impossible to fix the protection devices to boilers of different sizes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an intelligent safety protection device for natural gas boilers. Through the setting of a fan frame, an axial fan, a worm gear reducer and a drive motor, the drive motor drives the axial fan to rotate after being reduced in speed by the worm gear reducer. The axial fan swings up and down, thereby drawing away and discharging the air around the gas boiler, thereby dispersing the leaked natural gas, preventing the gas from accumulating, and effectively protecting the boiler. This can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent safety protection device for a natural gas boiler, comprising a support frame, an adjusting crossbar welded between two support frames, bolt holes on the adjusting crossbar, a limit block installed on the upper side of the adjusting crossbar, a locking groove provided in the center of the limit block, a limit shaft hole provided on the bottom side of the locking groove, a fan frame provided on the side of one of the support frames, an axial flow fan installed on the fan frame, a worm gear reducer installed on the side of the fan frame, a drive motor installed on the lower side of the worm gear reducer, and gas leak sensors installed at both ends of the other support frame.

[0006] Furthermore, a support arc plate is provided between the two adjusting crossbars, and a connecting ring is provided at one end of the axial fan.

[0007] Furthermore, the inner side of the connecting ring is provided with a threaded groove, and the fan frame is welded to the support frame.

[0008] Furthermore, the output shaft of the worm gear reducer is bolted to the housing of the axial fan, and the axial fan is connected to the fan frame via bearings.

[0009] Furthermore, the limiting block and the adjusting crossbar are connected through the bolt holes and bolts, and the two ends of the supporting arc plate are welded to the adjusting crossbar.

[0010] Furthermore, the output shaft of the drive motor is keyed to the input shaft of the worm gear reducer, and the worm gear reducer is bolted to the fan frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a fan frame, axial flow fan, worm gear reducer and drive motor, enables the drive motor to drive the axial flow fan to rotate after being reduced in speed by the worm gear reducer. This causes the axial flow fan to swing up and down, thereby drawing away and discharging the air around the gas boiler, thereby dispersing the leaked natural gas, preventing the gas from accumulating, and effectively protecting the boiler.

[0012] 2. This utility model, through the setting of an adjusting crossbar, a limiting block, a locking groove, a limiting shaft hole, and a bolt hole, allows the limiting block to be adjusted along the bolt hole on the adjusting crossbar, thereby adjusting the distance between the limiting blocks and enabling the limiting blocks to be used for limiting and fixing the installation of gas boilers of different sizes.
