Description

Technical Field

[0001] This application relates to the technical field of gas detection, and specifically discloses a portable harmful gas automatic alarm device. Background Art

[0002] At the present stage, the basic construction industry in our country has developed rapidly, and investment in the basic construction industry has been increased everywhere. However, many construction sites currently do not pay attention to the working environment of workers. Sometimes, before construction, due to environmental reasons, it is often impossible to know the real-time situation of the gas change in the environment immediately, so it is impossible to prevent the impending danger, and relevant personnel cannot evacuate in time after entering. Before or during construction, it is necessary to detect the gas concentration or leakage in mines, pipelines, confined spaces, etc., and a harmful gas automatic alarm device is required to detect and alarm harmful gases, reminding the staff that the concentration of harmful gases is too high to avoid harm to the users;

[0003] At present, the existing harmful gas automatic alarm devices are not easy to carry. For the sake of easy carrying, technology has changed to design this harmful gas automatic alarm device in a form that can be carried by people to achieve convenient carrying. However, other problems have followed, that is, for the detection of gases in narrow terrains such as vertical shafts and mine tunnels, since the harmful gas automatic alarm device adopted is in a form that can be carried by people, this device will not be able to detect some areas.

[0025] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, will detail the specific implementation manners, structures, features and their effects according to the present invention.

[0026] The reference numerals in the drawings of the specification include: main pipe 1, auxiliary pipe 2, hollow pipe 3, handle pipe 4, alarm 5, rotating handle 6, rotating rod 7, traction wire 8, protective layer 801, electric wire 802, connection point 9, connection column 10, harmful gas detection main body 11, winding wheel 12, collar 13.

[0027] The embodiment is as Figure 1 and Figure 2 shown:

[0028] The portable harmful gas automatic alarm device includes a detachable pipe structure, a harmful gas detection head detachably connected to the pipe structure, a traction wire 8 connected to the harmful gas detection head and arranged inside the pipe structure, a rotating assembly arranged on the pipe structure for driving the traction wire 8 to wind and unwind, an alarm 5 arranged on the pipe structure, and a storage battery electrically connected to the traction wire 8.

[0029] AsFigure 1 As shown, the pipe body structure includes a plurality of main pipes 1, a plurality of auxiliary pipes 2 and a handle rod. Both ends of the auxiliary pipe 2 are provided with hollow pipes 3. The surface of the hollow pipe 3 is provided with external threads. The inner wall of the main pipe 1 corresponding to the external thread connection part is provided with internal threads, and the external threads are threadedly connected with the internal threads.

[0030] Specifically: The assembly and disassembly of the pipe body structure are realized through threaded connection. When the pipe body structure is not installed, the space occupied by the device is small and it is convenient to carry. When the pipe body structure is installed, it is a rod-shaped structure and it is also convenient for people to carry.

[0031] As Figure 1 shown, the rotating assembly and the alarm 5 are both installed on the handle rod. The harmful gas detection head is installed on the main pipe 1 far from the handle rod and is threadedly connected with the main pipe 1. The harmful gas detection head includes a harmful gas detection body 11 and a connection column 10 fixedly connected to the bottom of the harmful gas detection body 11. The connection column 10 is threadedly connected with the main pipe 1. The harmful gas detection body 11 is a sensor, specifically a C6000A001 toxic and harmful gas detector. A connection point 9 is provided at the bottom of the connection column 10, and the connection point 9 is used to connect the traction wire 8.

[0032] Combined with the attached Figure 1 and the attached Figure 2 , the rotating assembly includes a rotating rod 7 and a rotating handle 6. The rotating rod 7 is rotatably connected inside the handle rod. The left end of the rotating rod 7 passes through the handle rod and is coaxially connected with the rotating handle 6. A winding wheel 12 is provided on the rotating rod 7. One end of the traction wire 8 is installed on the winding wheel 12, and the other end of the traction wire 8 is electrically connected to the harmful gas detection body 11 through the auxiliary pipe 2 and the main pipe 1.

[0033] Since the traction wire 8 is relatively soft and there is an unstable situation, therefore, an auxiliary stability structure for the smooth routing of the traction wire 8 is also included. The auxiliary stability structure is composed of a plurality of sleeve rings 13. The sleeve rings 13 are installed on the inner walls of the main pipe 1 and the auxiliary pipe 2, and the traction wire 8 is arranged through the sleeve rings 13.

[0034] In order to further protect the traction wire 8, the traction wire 8 includes an electric wire 802 and a protective layer 801. The electric wire 802 is placed inside the protective layer 801. One end of the electric wire 802 is connected to a storage battery to supply power to the harmful gas detection body 11. The alarm 5 is provided with a buzzer and a controller. The alarm 5 is electrically connected to the harmful gas detection body 11, and the alarm 5 is powered by the storage battery.

[0035] Since the harmful gas detection head may be thrown out under different working conditions, a protective shell should be provided on the outer periphery of the harmful gas detection head to prevent the harmful gas detection head from being damaged when it needs to be thrown out under working conditions.

[0036] Specific implementation process:

[0037] The first step is roughly divided into two types of working conditions that can be carried by humans: assemble this device, and then use the harmful gas detection head to detect the gas;

[0038] The second step is the working conditions that cannot be carried by humans, such as vertical terrain or narrow mine tunnels, etc. At this time, it is necessary to unscrew the connecting column 10 so that the harmful gas detection main body 11 is separated from the main pipe 1. If detecting from top to bottom, then only need to steadily control the traction line 8 so that the harmful gas detection main body 11 moves towards the destination. After the detection is completed, rotate the rotation handle 6 to make the winding wheel 12 rotate to retract the traction line 8, and then retract the harmful gas detection main body 11. If it is a working condition that requires throwing out the harmful gas detection main body 11, just throw out the harmful gas detection main body 11. The traction line 8 can assist. After the detection is completed, rotate the rotation handle 6 to make the winding wheel 12 rotate to retract the traction line 8.

[0039] The third step, if harmful gas appears, the harmful gas detection main body 11 is activated and emits an electrical signal. The controller receives this electrical signal and makes the buzzer start to achieve an alarm.

[0040] This device solves the problem that the existing harmful gas automatic alarm device cannot be compatible with both portability and the detection ability in narrow terrains at the same time.

[0041] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
