Description

Technical Field

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

[0002] Industrial production enterprises or chemical manufacturing industries often need to emit a large amount of high-temperature flue gas during production. Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. As the country's inspection on environmental protection continues to strengthen, in order to reduce the pollution of flue gas to the environment, it is necessary to regularly sample, test and analyze the emitted flue gas. Usually, the sampling tube is inserted into the flue to sample the flue.

[0003] The existing sampling tube has a fixed length, which makes its smoke sampling range relatively single and cannot sample smoke at different depths in the flue, affecting the accuracy of smoke detection. Therefore, there is a need for a smoke detection sampling device that can adjust the insertion depth of the sampling probe, obtain smoke data at more depths, and improve the accuracy of detection. Utility Model Content

[0004] To this end, the utility model provides a smoke detection sampling device, which uses a sampling extension component to solve the problem that the length of the sampling tube is fixed, so that the smoke sampling range is relatively single and the smoke at different depths of the flue cannot be sampled.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a smoke detection sampling device, comprising a sampler body, a cavity is opened inside the sampler body, a driving motor is fixedly installed inside the cavity, a threaded rod is fixedly connected to the output end of the driving motor, a sampling extension assembly is arranged outside the threaded rod, the sampling extension assembly comprises a slider, anti-rotation sliders are fixedly arranged on both sides of the slider, a through groove is opened inside the slider, obstacle avoidance grooves are opened on both sides of the through groove, a limiting groove is opened at the bottom of the through groove, an installation groove is opened at the bottom of the limiting groove, a spring is arranged inside the slider, a connecting plate is arranged at the bottom of the spring, adjustment blocks are fixedly arranged on both sides of the connecting plate, an insert block is fixedly arranged at the bottom of the connecting plate, a mounting block is arranged inside the mounting groove, a slot is opened on the top of the mounting block, a connecting ring is fixedly arranged at the bottom of the mounting block, and a sampling pipeline unit is arranged inside the connecting ring.

[0006] Preferably, the sampling pipeline unit includes a movable sampling tube, which passes through a connecting ring and is fixedly connected to the connecting ring, a sampling probe is fixedly provided at one end of the movable sampling tube, a fixed sampling tube is inserted into the inside of the movable sampling tube, the movable sampling tube is slidably connected to the fixed sampling tube, a sealing ring is embedded on the outside of the fixed sampling tube, and one end of the fixed sampling tube is fixedly connected to the sampler body.

[0007] Preferably, both ends of the threaded rod are connected to both side walls of the cavity via bearings.

[0008] Preferably, the sliding block is sleeved on the outside of the threaded rod and is connected to the threaded rod through threads.

[0009] Preferably, the two anti-rotation sliding blocks are slidably connected to the two side walls of the cavity respectively.

[0010] Preferably, the top of the spring is fixedly connected to the top of the through slot, and the bottom of the spring is fixedly connected to the connecting plate.

[0011] Preferably, the adjustment block passes through the obstacle avoidance groove and is slidably connected to the obstacle avoidance groove.

[0013] Preferably, the mounting block is disposed inside the mounting groove and is slidably connected to the mounting groove.

[0014] The utility model embodiment has the following advantages:

[0015] 1. The slider moves by rotating the threaded rod.

[0016] 2. By dragging the adjustment block upward along the obstacle avoidance groove, the adjustment block moves through the connecting plate to allow the insert block to be pulled out from the slot, thereby releasing the limit of the mounting block inside the mounting groove, making it easier to remove the movable sampling tube from the fixed sampling tube, and then to remove the fixed sampling tube from the sampler body, thereby facilitating the subsequent cleaning of the movable sampling tube and the fixed sampling tube.
