Description

Technical Field

[0001] The utility model belongs to the technical field of motor vehicle exhaust detection, in particular to a smoke detection device. Background Art

[0002] As environmental protection departments pay more and more attention to the phenomenon of excessive emissions of motor vehicle exhaust, it is usually necessary to use a smoke detection device to detect the smoke density of exhaust emissions from motor vehicles on the road.

[0003] A Chinese patent application with authorization publication number CN221007212U discloses a transmission-type smoke meter that uses spring tension to squeeze a plate against the inner wall of an exhaust pipe, thereby securing a sampling probe within the exhaust pipe. However, this device still suffers from the following drawbacks: During use, the inspector still needs to bend over or even crawl under the vehicle to install or remove the sampling probe from the vehicle's exhaust pipe, making it inconvenient to use. Furthermore, during the process of removing the sampling probe, the inspector's proximity to the vehicle's exhaust pipe can lead to the possibility of inhaling residual exhaust gas, potentially impacting their health. Therefore, there is an urgent need to develop a smoke detection device that can address these issues. Utility Model Content

[0004] The utility model provides a smoke detection device, the purpose of which is to solve the technical problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model discloses a smoke detection device, comprising a detection body; a hose connected to the detection body; a sampling probe connected to one end of the hose away from the detection body; a support sleeve is provided on the outer periphery of one end of the sampling probe close to the hose; an operating rod is radially fixed to the circumferential side wall of the support sleeve; and a clamping assembly is mounted on the operating rod for clamping the exhaust pipe of a motor vehicle after the sampling probe is inserted into the exhaust pipe of the motor vehicle.

[0007] As a preferred technical solution of the present invention, the clamping assembly includes a pair of first side-connecting columns radially fixed on the circumferential side wall of the support sleeve; the two first side-connecting columns are coaxially arranged, and the two first side-connecting columns are perpendicular to the operating rod; the two first side-connecting columns are fixed with a first sliding sleeve at one end away from the support sleeve; a guide rod parallel to the operating rod is slidably inserted in the two first sliding sleeves; the two guide rods are radially fixed with a first clamping rod parallel to the sampling probe at one end away from the operating rod; the two guide rods are connected by a push-pull sleeve at one end close to the operating rod; the push-pull sleeve The sleeve is slidably sleeved on the outer circumference of the operating rod; a transmission sleeve is coaxially arranged on the side of the push-pull sleeve close to the support sleeve; the transmission sleeve is slidably sleeved on the outer circumference of the operating rod; a pair of second side connecting columns parallel to the first side connecting columns are radially fixed on the circumferential side wall of the transmission sleeve; a second sliding sleeve is fixed on one end of the two second side connecting columns away from the transmission sleeve; the two second sliding sleeves are respectively slidably sleeved on the two guide rods; a second clamping rod parallel to the first clamping rod is radially fixed on the circumferential side wall of the two second sliding sleeves; a clamping space for the exhaust pipe of the motor vehicle is formed between the two second clamping rods and the two first clamping rods.

[0008] As a preferred technical solution of the present invention, a pair of extensions are axially arranged at one end of the transmission sleeve close to the push-pull sleeve; a pair of bearing bars parallel to the first side column are arranged between the transmission sleeve and the push-pull sleeve; the two bearing bars are arranged on opposite sides of the operating rod, and the two bearing bars are fixed on the operating rod; a pair of rotating shafts are connected side by side between the two bearing bars; gears are fixed on both rotating shafts; a first rack and a second rack are meshed on both gears; the two first racks and the two second racks are arranged parallel to the operating rod; the two first racks are respectively fixed on the two guide rods; the two second racks are respectively fixed on the two extensions.

[0009] As a preferred technical solution of the present invention, the push-pull sleeve is rotatably connected to an adjustment cylinder coaxially arranged with the operating rod at one end away from the transmission sleeve; the adjustment cylinder is threadedly fitted on the outer periphery of the operating rod.

[0010] The utility model has the following beneficial effects:

[0011] The utility model inserts the sampling probe into the exhaust pipe of the motor vehicle, clamps the exhaust pipe of the motor vehicle with a clamping assembly, and then places the operating rod on the ground. Then, the inspector moves away from the exhaust pipe of the motor vehicle to sample, collect, and inspect the exhaust gas of the motor vehicle. After the exhaust gas of the motor vehicle is inspected, the exhaust pipe of the motor vehicle is loosened by the clamping assembly, and the sampling probe is taken out from the exhaust pipe of the motor vehicle by holding the operating rod. This not only effectively improves the positioning effect of the sampling probe, but also avoids the problem in the prior art that the inspector needs to bend down or even crawl under the vehicle to install the sampling probe on the exhaust pipe of the motor vehicle or remove the sampling probe from the exhaust pipe of the motor vehicle, thereby effectively ensuring the inspection efficiency of the exhaust gas of the motor vehicle, and also avoids the problem in the prior art that the inspector may inhale the residual exhaust gas in the exhaust pipe of the motor vehicle due to the close proximity of the inspector to the exhaust pipe of the motor vehicle, thereby ensuring the health of the inspector.
