Description

Detection assembly

Technical Field

The utility model relates to the technical field of detection devices, in particular to a detection assembly, and particularly aims at tail gas detection of a diesel generator set.

Background

At present, the diesel generator set has national three emission standards, but the diesel generator set does not have tail gas detection function after leaving the factory, so that perfect execution standards cannot be ensured. The gas probe is arranged at the tail gas discharge port to detect vulcanized gas, nitriding gas, carbon dioxide and the like, meanwhile, collected data are transmitted into the host machine, and tail gas detection can be realized, but the existing gas probe is fixed by utilizing a bracket or a mounting seat, and the following problems exist in the mounting mode:

1. the gas probe is usually arranged at the outlet of the exhaust pipe of the diesel generator set and is directly detected, and although the installation and the maintenance are simple, the gas probe is easily damaged by external influences, or the position of the gas probe can be directly regulated by the external world, so that the detection result is influenced.

2. Considering the later maintenance, the device is also ensured on the basis of solving 1, and the assembly and disassembly are simple.

The tail gas detection device has no related components, and achieves the purposes of simple assembly and disassembly and high safety coefficient when the gas detection probe can realize the tail gas detection of the diesel generating set.

Disclosure of Invention

The present utility model is directed to a detection assembly, which solves the above-mentioned problems.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a detection subassembly, detection subassembly includes sensor, fixture, installation tube, bolt, the outside of installation tube and diesel generator's blast pipe outside all be provided with annular installation boss, the installation boss on set up the through-hole, the side of installation tube and be located two through-holes and seted up the installation screw, fixture including can stretch into the passageway part in the through-hole and be located the main part in the through-hole outside, main part and passageway part run through set up the cavity that is used for holding the sensor, passageway part outside set up with the mutual screw thread fit's of installation screw, the outline of main part be the rectangle, the width of this rectangle is less than the distance of two adjacent through-holes, the length of rectangle is greater than the distance of two adjacent through-holes, the bolt wear to establish in the through-hole of two installation bosses, the sensor fixed setting in the cavity.

Further, the lower opening of the installation tube is provided with an annular bulge along the inner side surface, the annular bulge is in slidable fit with the inner side surface of the exhaust pipe, and the annular bulge is provided with sealing rubber on the lower end surface.

The utility model has the technical effects and advantages that:

this application has realized two purposes through setting up sensor, fixture, installation tube, bolt, first, through fixture fixed sensor, then install fixture at the installation tube, pass through the bolt with the installation tube at last and install on the blast pipe, so realize detachable installation, the dismantlement process needs to pass through the dismantlement bolt, when having improved the security, the loading and unloading degree of difficulty reduces, easy operation. And secondly, the installed clamp is limited by two adjacent bolts, cannot rotate, and further cannot be directly separated from the sensor, so that the safety is improved.

Fig. 2 is a cross-sectional view of the sensing assembly of the present utility model mounted on an exhaust pipe.

Fig. 3 is a top view of the mounting tube of the present utility model.

In the figure: the device comprises a fixture-1, a mounting pipe-2, a bolt-3, a generator-4, an exhaust pipe-5, a mounting boss-6, a through hole-7, a mounting screw hole-8, a channel part-9, a main body part-10, a cavity-11, an annular protrusion-12 and sealing rubber-13.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides a detection assembly shown in the attached drawing, the detection assembly comprises a sensor (not shown), a clamp 1, a mounting pipe 2 and a bolt 3, wherein annular mounting bosses 6 are arranged on the outer side of the mounting pipe 2 and the outer side of an exhaust pipe 5 of a diesel generator 4, through holes 7 are formed in the mounting bosses 6, mounting screw holes 8 are formed in the side surfaces of the mounting pipe 6 and between the two through holes 7, the clamp 2 comprises a channel part 9 which can extend into the through holes 7 and a main body part 10 which is positioned on the outer side of the through holes 7, a cavity 11 for accommodating the sensor is formed in the outer side of the channel part 10 and penetrates through the channel part 9, threads which are in threaded fit with the mounting screw holes 8 are formed in the outer side of the channel part 9, the outer contour of the main body part 10 is rectangular, the width of the rectangle is smaller than the distance between the two adjacent through holes 7, the bolt 3 is arranged in the through holes of the two mounting bosses 6 in a penetrating manner, the sensor is fixedly arranged in the cavity 11, the annular boss 12 is arranged at the inner side surface of the annular boss 2 in a sealing manner, and the annular boss 12 is arranged at the inner side surface of the annular boss 12 and can be in a sealing manner, and the sealing effect of the sealing boss 13 is poor is solved.

The above description is installed for assembly, at this time, the clamp 1 is located between the two bolts 3, because the clamp 1 is sized, the clamp 1 is screwed into the installation screw hole 8, but the clamp 1 cannot be smoothly rotated, so far, the clamp 1 is prevented from being separated, and the sensor is prevented from being moved.

The sensor is in communication connection with a detection host, the detection host can be arranged on the diesel generator 4, and the detection host obtains the air quality in the exhaust pipe 5 through the data of the sensor so as to realize the detection purpose.
