Embodiment 1

[0039] Such as figure 1 As shown, the present embodiment provides an automatic fire alarm device 10 for an excavator engine compartment, and the automatic fire alarm device 10 for an excavator engine compartment includes a temperature sensor 12, a smoke sensor 13, a carbon monoxide sensor 14, a main control module 11 and a wireless communication module 15.

[0040] The temperature sensor 12 , the smoke sensor 13 , the carbon monoxide sensor 14 and the wireless communication module 15 are all connected to the main control module 11 . Wherein, the carbon monoxide sensor 14 may also be called a carbon monoxide sensor.

[0041] Specifically, the temperature sensor 12, the smoke sensor 13 and the carbon monoxide sensor 14 are installed at corresponding positions in the engine compartment of the excavator, for example, they can be arranged in the engine compartment that is not easy to be touched frequently and is easy to collect data. Location; also, for example, it can be set in ...

Embodiment 2

[0074] figure 2A structural schematic diagram of an automatic fire alarm device 10 for an excavator engine compartment proposed by the second embodiment of the present invention is shown. Compared with Embodiment 1, the automatic fire alarm device 10 for the engine compartment of the excavator further includes a display module 16 connected to the main control module 11 , a prompt module 17 and a positioning module 18 .

[0075] The display module 16 is used for displaying the temperature information, the smoke concentration information and the carbon monoxide concentration information for users to view when the excavator is started.

[0076] In this embodiment, the display module 16 may be a liquid crystal display.

[0077] Further, in order to enable the liquid crystal display to clearly display the temperature information, the smoke concentration information and the carbon monoxide concentration information sent by the main control module 11, the liquid crystal display can...

Embodiment 3

[0084] image 3 A schematic structural view of an automatic fire alarm device 10 for an excavator engine compartment proposed by the third embodiment of the present invention is shown. Compared with Embodiment 2, the excavator engine compartment fire automatic alarm device 10 further includes a camera module 19 and a lighting module 20 connected to the main control module 11 .

[0085] The camera module 19 is used for taking video information in the engine compartment.

[0086] The lighting module 20 is used to provide lighting when the camera module 19 takes pictures.

[0087] Specifically, the camera module 19 in the excavator at night cannot clearly capture the video information in the engine compartment. Therefore, in order to improve the clarity of the video information in the engine compartment, the camera module 19 also shoots the video in the engine compartment. Illumination is provided during information, so that the camera module 19 can capture the video informatio...

Abstract

The invention discloses an automatic fire alarm device for an engine compartment fire of an excavator and an excavator. The device comprises a main control module installed in an engine compartment, atemperature sensor, a smoke sensor, a carbon monoxide sensor and a wireless communication module, wherein the temperature sensor, the smoke sensor, the carbon monoxide sensor and the wireless communication module are connected with the main control module; the temperature sensor is used for acquiring temperature information in the engine compartment; the smoke sensor is used for acquiring smoke concentration information in the engine compartment; the carbon monoxide sensor is used for acquiring concentration information of carbon monoxide in the engine compartment; and the main control moduleis used for judging whether an alarm condition is reached according to the temperature information, the smoke concentration information and the concentration information of the carbon monoxide and sending alarm information to a terminal of an owner and / or a server through the wireless communication module when the alarm condition is reached. According to the technical scheme, whether the alarm condition is reached is judged according to the real-time information of the temperature, the smoke concentration and the carbon monoxide, and the alarm information is sent to the owner and / or the server when the alarm condition is reached.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to an automatic fire alarm device for an engine compartment of an excavator and an excavator. Background technique [0002] During the normal operation of the excavator, the temperature of the engine compartment is high. Due to the small space of the engine compartment and the good sealing performance, although a lot of flame-retardant sponges are pasted on the edge of the engine compartment, the engine temperature is very high or open flames (sparks) appear outside. All will ignite the sponge, which will cause a fire. Once a fire occurs, unless it is found and extinguished in time, the excavator will be severely damaged. Although the excavator equipment is equipped with a fire extinguisher as standard in the cab, when a fire occurs, especially when the excavator is shut down, the operator or the owner cannot detect the fire in time. Arrive at the scene for fire fighting. Cont...
