Description

Technical Field

[0001] The utility model relates to the technical field of smoke detection, in particular to a smoke detection device with a protection mechanism. Background Art

[0002] Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides, and the smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products. Flue gas pollution to the environment is a complex pollution of multiple poisons. Before the flue gas is discharged, a detection device is needed to detect the flue gas to determine whether it meets the emission standards.

[0003] However, the existing smoke detection device lacks protective measures for the probe. When detecting smoke, the probe needs to be inserted into the smoke detection port so that the smoke contacts the probe. However, some smoke detection ports are very narrow, and the probe is prone to collision and friction during insertion and withdrawal, thereby affecting the service life of the probe. Therefore, a smoke detection device with a protective mechanism is proposed. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a smoke detection device with a protective mechanism includes a detector 1, a handle 2 is fixedly connected to the bottom of the detector 1, a control panel 3 is arranged on the rear end side wall of the detector 1, a detection rod 4 is arranged at the front end of the detector 1, a probe 9 is fixedly connected to the front end of the detection rod 4, and a protective mechanism acting on the probe 9 is arranged on the detection rod 4;

[0022] The protection mechanism includes a protection plate 5, a movable sleeve 6, a rotating member 7, an adjusting screw 8 and a fixed plate 10. The fixed plate 10 is sleeved on the front end side wall of the detection rod 4 and fixedly connected to the detection rod 4. The rotating member 7 is sleeved on the outer surface of the detection rod 4 and is rotatably connected to the detection rod 4. The end of the rotating member 7 close to the probe 9 is fixedly connected with the adjusting screw 8, and the adjusting screw 8 is made of cemented carbide. The detection rod 4 passes through the adjusting screw 8 and is rotatably connected to the adjusting screw 8. The outer surface of the adjusting screw 8 is sleeved with a movable sleeve 6, and the inner wall of the movable sleeve 6 is provided with an internal thread 13. The movable sleeve 6 and the adjusting screw 8 are connected by threaded cooperation. The end of the movable sleeve 6 close to the probe 9 is fixedly connected with two protection plates 5, and the two protection plates 5 are symmetrically distributed on both sides of the probe 9. The two protection plates 5 are respectively slidably inserted in the guide grooves 14 provided in the fixed plate 10.

[0023] Among them, a plurality of anti-slip grooves are provided on the outer surface of the rotating member 7 .

[0024] The anti-slip groove can increase the friction between the palm of the user and the rotating member 7.

[0025] A first limiting plate 11 is fixedly connected to the outer wall of the protection plate 5 at the front side of the fixing plate 10 , and a second limiting plate 12 is fixedly connected to the outer wall of the protection plate 5 at the rear side of the fixing plate 10 .

[0026] Such an arrangement can ensure that the protective plate 5 will not escape from the guide groove 14 .

[0027] The utility model provides a smoke detection device with a protection mechanism, and the specific working principle is as follows:

[0028] When in use, the rotating part 7 is rotated to drive the adjusting screw 8 to rotate. Since the protective plate 5 is slidably inserted in the guide groove 14, the movable sleeve 6 fixedly connected to the protective plate 5 cannot rotate. When the adjusting screw 8 is rotated, the movable sleeve 6 will move along the axis of the adjusting screw 8. When it is necessary to use the probe 9 in a narrow position, the movable sleeve 6 can be controlled to move in the direction of the probe 9 before extending and withdrawing the probe 9, so that the two protective plates 5 surround the probe 9. In this way, there is no need to worry about the problem of collision and friction when the probe 9 is extended into and withdrawn from the narrow detection position. When the probe 9 reaches the detection position, the protective plate 5 can be restored to its initial position to prevent the protective plate 5 from affecting the contact between the probe 9 and the smoke.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
