[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-5 As shown, the technical solution adopted by the present invention is specifically as follows: a portable hand-held Lingemann black smoke detection device, comprising a flue detection box 1, a manual telescopic component is rotatably provided on one side of the flue detection box 1, a first connecting rod 2 is provided on the manual telescopic component, an arc-shaped hand-held rod 3 is provided on the first connecting rod 2, and the bottom of the first connecting rod 2 is rotatably provided on the second connecting rod 4, a through hole is opened at one end of the second connecting rod 4, a movable rod 5 is movably provided inside the through hole, V-shaped brackets 6 for fixing the entire device on the ground are provided at both ends of the movable rod 5, a support block 7 is provided on the V-shaped bracket 6, and a power box 8 is installed at one end of the second connecting rod 4, and an arc-shaped support plate 9 for supporting the arm is rotatably provided on the top of the power box 8.

[0026] Its working principle is: when people use it, they hold the arc-shaped hand-held rod 3 with their right hand, and then perform detection through the flue detection box 1. During the detection, the manual telescopic component is pushed by the left hand to change the length of the flue detection box 1, and then the first connecting rod 2 is rotated on the second connecting rod 4 to adjust the angle. The power box 8 provides power, and the arc-shaped support plate 9 supports the arms of people holding it to prevent fatigue. However, when people hold it for detection, because the whole device has a certain weight, when the detection time is long or there are many detections, people will feel tired. At this time, the V-shaped bracket 6 drives the movable rod 5 to rotate inside the through hole, so that the whole device is supported on the ground. People only need to adjust the length and the rotation angle to complete the detection. This setting can reduce people's labor and improve work efficiency.

[0027] Among them, a smoke channel is arranged on the smoke duct detection box 1, and collection ports are respectively arranged on both sides of the smoke channel. Black smoke can enter the smoke channel through the collection ports. A camera is arranged inside the entire smoke duct for shooting black smoke passing through the collection ports.

[0028] It should be noted that before the device is prepared, the mobile power supply needs to be installed in the power box 8 to provide power for the entire device; during use, the box can be opened at any time to replace the mobile power supply, so as to replenish the power in time, shorten the time consumption caused by charging, and is convenient and fast.

[0029] A fixing plate is provided on the arc-shaped hand-held rod 3, and a tablet computer 10 is provided on the fixing plate. By adopting the tablet computer 10 to control the operation of the entire work and data collection and analysis, the operation interface is larger, which makes it easier for the staff to perform the operation work; when the equipment needs to work, the tablet computer 10 is placed on the operation fixing plate, and it is electrically connected to the mobile power supply in the power box 8 and the flue as a whole; when work is not needed, the tablet computer 10 can be removed and put away to avoid bumps.

[0030] It should be noted that the fixing plate is connected to the tablet computer 10 by snap-fitting, which facilitates installation and removal of the tablet computer 10.

[0031] The movable rod 5 is interference-connected with the through hole, and such a setting can prevent sliding from occurring easily when the movable rod 5 is rotated for support.

[0032] like Figure 4 As shown, the V-shaped bracket 6 is divided into an upper section 11 and a lower section 12. The upper section 11 is provided with a threaded hole, and the lower section 12 is provided with a threaded rod 14. The threaded rod 14 is threadedly connected to the threaded hole. This arrangement can adjust different heights to accommodate people of different heights.

[0033] The bottom of the support block 7 is cut with a plane, and the purpose of providing the plane is to increase the fixing area, thereby improving the fixing effect.

[0034] It should be noted that: when not in use, Figure 2 As shown, the V-shaped bracket 6 drives the movable rod 5 to rotate inside the through hole, so that it is located on the handheld storage component for storage and is convenient for subsequent carrying.

[0035] The manual telescopic assembly includes a third connecting rod 15 connected to one side of the flue detection box 1, a hollow cylinder 16 connected to the first connecting rod 2, a slide groove 17 matching the cavity thereof is provided on the hollow cylinder 16, a push rod 18 is arranged inside the slide groove 17, a third connecting rod 15 is movably arranged inside the hollow cylinder 16, and the third connecting rod 15 is connected to the push rod 18.

[0036] When in use, the push rod 18 moves inside the slide groove 17, and the push rod 18 drives the third connecting rod 15 to move inside the hollow tube 16, so that the third connecting rod 15 drives the flue detection box 1 to move, thereby adjusting the length.

[0037] The working principle of the utility model is as follows: when people use it, they hold the arc-shaped hand-held rod 3 with their right hand, and then perform detection through the flue detection box 1. During the detection, the manual telescopic component is pushed by the left hand to change the length of the flue detection box 1, and then the first connecting rod 2 is rotated on the second connecting rod 4 to adjust the angle. The power box 8 provides power, and the arc-shaped support plate 9 supports the arms of people holding the device to prevent fatigue. However, when people hold the device for detection, because the whole device has a certain weight, when the detection time is long or there are many detections, people will feel tired. At this time, the V-shaped bracket 6 drives the movable rod 5 to rotate inside the through hole, so that the whole device is supported on the ground. People only need to adjust the length and the rotation angle to complete the detection. Such a setting can reduce people's labor and improve work efficiency.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
