[0025] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0026] Reference Figure 1-4 The high-safety temperature-compensated gas detector of the present utility model embodiment includes a base 1, a mounting base 2 is fixedly connected to the side of the base 1, a connecting column 3 is fixedly connected to the right side of the base 1, a placement groove 14 is opened inside the base 1, a circuit board 8 is arranged inside the placement groove 14, a display screen module 7 is arranged on the side of the circuit board 8, an upper cover 6 is arranged on the side of the display screen module 7 away from the circuit board 8, a gas detection sensor 9 is arranged on the surface of the circuit board 8, a temperature sensor 10 is arranged on the right side of the gas detection sensor 9, a control unit 11 is arranged below the temperature sensor 10, and a clamping rod 13 is arranged on the side of the control unit 11;

[0027] An audible and visual alarm 5 is fixedly connected to the right side of the connecting column 3, a gas delivery detection tube 4 is fixedly connected to the bottom of the base 1, a fan body 12 is fixedly connected to the side of the base 1, a drive motor 15 is arranged inside the fan body 12, and a rotating rod 16 is fixedly connected to the output end of the drive motor 15. The outer surface of the rotating rod 16 is fixedly connected to fan blades 17, and there are two fan blades 17. A pipe 18 is arranged on the side of the fan body 12, and the side of the pipe 18 away from the fan body 12 passes through the interior of the placement slot 14.

[0028] The above structure, by setting a temperature sensor 10 and a fan body 12, realizes that when the temperature sensor 10 detects that the temperature inside the gas detector is too high, the temperature sensor 10 drives the drive motor 15 inside the fan body 12 to start working through the controller, so that the drive motor 15 can drive the rotating rod 16 to rotate, and the outer surface of the rotating rod 16 is fixedly connected with a fan blade 17, so that the fan blade 17 can rotate, and the fan body 12 is fixedly connected to the base 1 through the pipe 18, so that the pipe 18 can suck out the hot air inside the placement slot 14 opened inside the base 1, so that the gas detection sensor 9 will not have inaccurate detection data, thereby avoiding the problem of inaccurate detection data and avoiding the possibility of spontaneous combustion inside the gas detector.

[0029] By setting up the base 1 and the upper cover 6, it is achieved that when the external environment is at high temperature, the high temperature situation that may occur inside the gas detector is alleviated under the action of the thermal insulation layer coated on the surface of the base 1 and the upper cover 6, wherein the material of the thermal insulation layer is ceramic fiber. The low thermal conductivity of ceramic fiber effectively isolates heat and reduces heat transfer. Ceramic fiber can withstand high temperature environment and is suitable for the protection of high-temperature industrial equipment and furnace bodies. The ceramic fiber coating is light and will not increase the structural burden. It has good tolerance to most chemical substances, extends the service life of the equipment, helps reduce energy consumption and improve energy efficiency in industrial applications, and the excellent thermal insulation performance of the ceramic fiber coating can reduce heat accumulation inside the detector and ensure the stability and accuracy of the equipment. Especially in an environment with large temperature fluctuations, the ceramic fiber coating can buffer the thermal shock caused by temperature changes and protect the electronic components and sensitive elements of the detector from damage. The ceramic fiber coating can also improve the surface hardness and wear resistance of the gas detector, reduce the risk of physical damage, thereby avoiding the possibility of misjudgment of the alarm device and avoiding the need for manual shutdown.

[0030] Working principle: When the temperature sensor 10 detects that the temperature inside the gas detector is too high, the temperature sensor 10 drives the drive motor 15 inside the fan body 12 through the controller to start working, so that the drive motor 15 can drive the rotating rod 16 to rotate, and the outer surface of the rotating rod 16 is fixedly connected with the fan blade 17, so that the fan blade 17 can rotate, and the fan body 12 and the base 1 are fixedly connected through the pipe 18, so that the pipe 18 can suck out the hot air inside the placement slot 14 opened inside the base 1, so that the gas detection sensor 9 will not have inaccurate detection data. When the external environment is high temperature, under the action of the thermal insulation layer coated on the surface of the base 1 and the upper cover 6, the high temperature inside the gas detector is alleviated.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
