Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to an electric welding smoke detection device. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in enterprise factories, including various toxic chemical gases and particulate matter such as dust. After industrial waste gas is discharged into the atmosphere, it will cause air pollution. After these harmful substances enter the human body through different pathways, some will cause direct harm, while others will accumulate in the human body. After a large amount of dust is inhaled, it is easy to cause diseases such as pneumoconiosis, seriously affecting the safety and health of workers in industrial areas. Electric welding fume is a type of industrial waste gas with a very complex composition, which contains a large amount of dust particles. Therefore, before discharge, it is necessary to first use a smoke detection device to measure the particulate content in the electric welding fume. The electric welding fume can only be discharged when the particulate matter is lower than the emission standard. The smoke detection device determines the particulate content in the electric welding fume by emitting light and measuring the scattering of light. It can quickly measure the particulate content of the electric welding fume in real time. The detection has high accuracy and is simple and convenient to operate.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: when the existing welding smoke detection device detects welding smoke containing a lot of water vapor, the water vapor mixed with the particulate matter in the welding smoke enters the detection device, which can easily cause the welding smoke and water vapor to merge and adhere to the light receiving device of the welding smoke detector, thereby causing the light to be difficult to fully penetrate into the light receiving device due to a layer of particulate adhesion layer attached to the surface of the light receiving device, which can easily lead to inaccurate detection results. Utility Model Content

[0004] The utility model aims to provide a welding smoke detection device with accurate detection and shielding prevention in view of the defects and shortcomings of the prior art.

[0006] A further improvement is that the magnetic pulling block includes a pulling block slidably arranged on the outer wall of the mainframe shell and a magnetic block arranged on the inner wall of the pulling block.

[0007] A further improvement is that a rolling wheel is provided between the pulling block and the outer wall of the mainframe shell.

[0008] A further improvement is that a sliding bracket slidably connected to the inner wall of the pull block is provided between the rolling wheel and the pull block, and a buffer spring is provided between the sliding bracket and the inner wall of the pull block.

[0009] A further improvement is that a handle is provided on the side of the pull block away from the mainframe housing.

[0010] A further improvement is that: a guide groove is provided on the outer wall of the main housing, and the inner wall of the guide groove is slidably connected to the pull block.

[0011] A further improvement is that the driven scraper block comprises a moving base block slidably arranged on the side wall of the light receiving plate and a magnetic block embedded in the inner wall of the moving base block, and a shovel head is also arranged at the bottom of the moving base block.

[0012] A further improvement is that a buffer column is provided between the side wall of the magnetic attraction block and the inner wall of the movable base block.

[0013] A further improvement is that a plurality of air guides are provided on the side of the movable base block away from the light receiving plate.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the utility model is in use, if there are attachments attached to the light receiving plate causing the light to be blocked, the pulling block can be pulled at this time to drive the driven scraper block to move through the magnetic force, and as the driven scraper block moves, the attachments attached to the light receiving plate are scraped off through the shovel head, thereby avoiding the light receiving port on the light receiving plate being blocked by the attachments and affecting the detection structure, and making cleaning more convenient.

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See also Figure 1-3 As shown, the technical solution adopted in this specific embodiment is: a welding smoke detection device, including a mainframe housing 1 and an air inlet pipe 2 arranged on one side of the mainframe housing 1 and connected to the mainframe housing 1, the top of the mainframe housing 1 is also provided with an exhaust pipe 3 connected to the mainframe housing 1, the bottom of the inner wall of the mainframe housing 1 is provided with a light receiving plate 13, the inner wall side wall of the mainframe housing 1 is provided with a magnetic pull block 15 slidably provided on the outer wall of the mainframe housing 1, and the magnetic pull block 15 includes a sliding device A pull block 21 is placed on the outer wall of the main housing 1 and a magnetic block 22 is arranged on the inner wall of the pull block 21. A driven scraper block 14 is slidably arranged at the corresponding position of the magnetic pull block 15 on the side wall of the light receiving plate 13. The driven scraper block 14 includes a moving base block 31 slidably arranged on the side wall of the light receiving plate 13 and a magnetic block 33 embedded in the inner wall of the moving base block 31. A shovel head 32 is also arranged at the bottom of the moving base block 31. When an attachment appears on the light receiving plate 13, the magnetic pull block 15 is pulled to make the driven scraper plate 14 move in the magnetic pull block 15. The welding dust is moved under the action of the light receiving plate 13, and the attachments on the receiving plate 13 are scraped off. When in use, the welding smoke is introduced into the main housing 1 from the air inlet pipe 2, and the main housing 1 is filled with welding smoke. At this time, the light-emitting frame 11 is started to generate light and aim at the light receiving plate 13 to emit light. The light is scattered by the welding smoke and is received by the light receiving plate 13. At this time, the concentration of welding smoke particles can be obtained through the scattering data. When attachments are attached to the light receiving plate 13, the magnetic suction pull is pulled. The force block 15 moves the pulling block 21 of the magnetic pulling block 15 and drives the magnetic block 22 to move at the same time, thereby synchronously driving the magnetic block 33 of the driven scraper block 14 slidably disposed on the light receiving plate 13 to move, and the moving base block 31 and the shovel head 32 are driven to move at the same time through the magnetic block 33. At this time, the attachments on the light receiving plate 13 can be scraped off by moving the shovel head 32, thereby preventing the light receiving port on the light receiving plate from being blocked by the attachments and affecting the detection structure, and making cleaning more convenient;

[0021] A rolling wheel 23 is also provided between the pull block 21 and the outer wall of the host housing 1, which is beneficial to reduce the friction resistance between the pull block 21 and the host housing 1, making the pulling smoother;

[0022] A sliding bracket 24 is provided between the rolling wheel 23 and the pull block 21 and is slidably connected to the inner wall of the pull block 21. A buffer spring 26 is provided between the sliding bracket 24 and the inner wall of the pull block 21 to help buffer the lateral pressure generated by the magnetic block 22, thereby avoiding excessive resistance when the pull block 21 moves.

[0023] The pull block 21 is also provided with a pull handle 27 on one side away from the main housing 1, which is conducive to better transmission of the pulling force to the pull block 21;

[0024] A buffer column 35 is provided between the side wall of the magnetic block 33 and the inner wall of the mobile base block 31, which is helpful to buffer the lateral magnetic attraction force received by the magnetic block 33, thereby preventing the magnetic block 33 from being pulled by the attraction force at the moment of being attracted by the magnetic block 22, causing the light receiving plate 13 to be overly squeezed and damaged;

[0025] A plurality of air guides 34 are provided on the side of the movable base block 31 away from the light receiving plate 13. In this embodiment, three air guides 34 are provided, which is beneficial for guiding the airflow upward and reducing the airflow resistance generated when the movable base block 31 moves downward.

[0026] Working principle of the utility model: when the utility model is used, the welding smoke is introduced into the main housing 1 from the air inlet pipe 2, and the main housing 1 is filled with welding smoke. At this time, the light-emitting frame 11 is started, so that the light-emitting frame 11 generates light and emits light at the light receiving plate 13. The light is received by the light receiving plate 13 after being scattered by the welding smoke. At this time, the concentration of welding smoke particles can be obtained through the scattering data. When attachments are attached to the light receiving plate 13, the magnetic pulling block 15 is pulled at this time, so that the pulling block 21 of the magnetic pulling block 15 moves and drives the magnetic block 22 to move at the same time, and then synchronously drives the magnetic block 33 of the driven scraper block 14 slidingly set on the light receiving plate 13 to move, and the moving base block 31 and the shovel head 32 are driven to move at the same time through the magnetic suction block 33. At this time, the attachments on the light receiving plate 13 can be shoveled out and scraped off by moving the shovel head 32, thereby avoiding that the light receiving port on the light receiving plate is blocked by the attachments and affecting the detection structure, and making cleaning more convenient.
