[0002] Detection equipment refers to devices, instruments or systems used to measure, inspect, analyze and judge whether products or processes meet the specified requirements. They play a crucial role in fields such as industry, scientific research, medical treatment, and environmental protection, ensuring product quality, improving production efficiency, and safeguarding people's life health and environmental safety.

[0003] Automobile exhaust gas generally has a relatively high temperature. When the exhaust gas detection equipment works continuously, the internal temperature will continue to rise. If the heat inside the equipment is not discharged in time, it may cause the performance of the electronic components of the equipment to decline, thus affecting the accuracy of the detection results. High temperature will also cause the surface temperature of the equipment to rise, which will not only affect the operation experience of the operator, but also may scald the operator. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when the above equipment is used, due to the lack of a heat dissipation device in the exhaust gas detection equipment, the accuracy of the detection results is affected and the operation safety risk increases, and thus a motor vehicle exhaust gas detection equipment is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a motor vehicle exhaust gas detection equipment, including a heat dissipation mechanism, and a cleaning mechanism is fixedly installed on one side of the outer wall of the heat dissipation mechanism;

[0006] The heat dissipation mechanism includes a bottom plate, two push rods are fixedly installed on one side of the outer wall of the bottom plate, a detection box is fixedly installed on the top of the bottom plate, a detector is arranged at the bottom of the inner wall of the detection box, a filter screen is fixedly inserted into the inner surface wall of the detection box, four universal wheels are fixedly installed at the bottom of the bottom plate, a group of first holes are opened on the outer surface wall of the detection box, five groups of second holes are opened on the outer surface wall of the detection box, and cooling pipes are fixedly inserted between the inner surface walls of the five groups of second holes.

[0007] Preferably, the outer surfaces of the five cooling pipes are fixedly sleeved with first heat dissipation fins, and the outer surfaces of the five first heat dissipation fins are fixedly connected to the inner surface wall of the detection box.

[0010] Preferably, a movable block is threadedly connected to the outer surface wall of the threaded rod, and a cleaning brush is fixedly installed on one side of the outer wall of the movable block.

[0011] Preferably, two sliders are fixedly installed on the outer surface wall of the movable block, and guide rails are movably sleeved on the outer surface walls of the two sliders.

[0012] Preferably, one side of the outer wall of the detection box is fixedly connected to one side of the outer wall of the motor. The outer surface of the threaded rod is movably inserted between the inner surface walls of a set of the first holes, and the inner surface wall of the detection box is fixedly connected to the outer surface walls of the two guide rails.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0014] 1. In the present utility model, under the action of the heat dissipation mechanism, when vehicle exhaust enters the interior of the detection box, the first heat dissipation fin will absorb the heat in the exhaust gas. Subsequently, the heat dissipation pipe will promptly bring the heat to the second heat dissipation fin, and the heat of the exhaust gas will be quickly dissipated to the outside through the fan. By rapidly reducing the temperature of the exhaust gas, it can effectively prevent the temperature in the detection box from being too high, which may cause a decrease in the performance of electronic components and the accuracy of the detection results. At the same time, it can also prevent the internal components of the device from accelerating aging due to high temperature, reducing the cost of equipment maintenance and replacement. The push rod and the universal wheels cooperate with each other, which can facilitate people to move the device and improve the practicability of the device.

[0015] 2. In the present utility model, under the cooperation of the heat dissipation mechanism and the cleaning mechanism, the filter screen can remove solid particulate matter in the exhaust gas, ensuring the purity of the exhaust gas sample, thereby improving the accuracy of the detection results. The cleaning brush can promptly clean the filter screen to avoid a decrease in the filtering effect and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification

[0025] Embodiment 1, as Figures 1 - 4 shown, the present invention provides a motor vehicle exhaust gas detection device, including a heat dissipation mechanism 1, and a cleaning mechanism 2 is fixedly installed on one side of the outer wall of the heat dissipation mechanism 1

[0026] The heat dissipation mechanism 1 includes a base plate 101, two push rods 102 are fixedly installed on one side of the outer wall of the base plate 101, a detection box 103 is fixedly installed on the top of the base plate 101, a detector 104 is arranged at the bottom of the inner wall of the detection box 103, a filter screen 105 is fixedly inserted into the inner surface wall of the detection box 103, four universal wheels 106 are fixedly installed at the bottom of the base plate 101, a group of first holes 107 are opened on the outer surface wall of the detection box 103, five groups of second holes 108 are opened on the outer surface wall of the detection box 103, a cooling pipe 109 is fixedly inserted between the inner surface walls of the five groups of second holes 108, a first heat sink 110 is fixedly sleeved on the outer surface wall of each of the five cooling pipes 109, and the outer surface walls of the five first heat sinks 110 are fixedly connected to the inner surface wall of the detection box 103, a group of second heat sinks 111 are fixedly sleeved between the outer surface walls of the five cooling pipes 109, and the outer surface walls of the group of second heat sinks 111 are fixedly connected to one side of the outer wall of the detection box 103, and a fan 112 is fixedly installed between the outer surface walls of the group of second heat sinks 111

[0027] The effect achieved by the entire Embodiment 1 is that the push rod 102, the bottom plate 101, and the universal wheels 106 cooperate with each other, which can facilitate people to move the detection device and improve the flexibility of the device. When the tail gas enters the interior of the detection box 103, the first heat sink 110 can promptly reduce the temperature of the tail gas and transfer the absorbed heat to the second heat sink 111 through the cooling pipe 109. The second heat sink 111 will dissipate the heat to the outside with the assistance of the fan 112. By reducing the temperature of the tail gas, it is possible to avoid the influence of high temperature on the accuracy of the detection results and reduce the service life of electronic components. The filter screen 105 can quickly filter out solid particles in the tail gas, avoid the influence of particles on the measurement accuracy of the detector 104, and reduce the cleaning and maintenance frequency of the internal components of the device.

[0028] Embodiment 2 is as Figures 2 - 4 shown. The cleaning mechanism 2 includes a motor 201. A threaded rod 202 is fixedly installed at the output end of the motor 201. An active block 203 is threadedly connected to the outer surface of the threaded rod 202. A cleaning brush 204 is fixedly installed on one side of the outer wall of the active block 203. Two sliders 205 are fixedly installed on the outer surface of the active block 203. Guide rails 206 are movably sleeved on the outer surfaces of the two sliders 205. One side of the outer wall of the detection box 103 is fixedly connected to one side of the outer wall of the motor 201. The outer surface of the threaded rod 202 is movably inserted between the inner surfaces of a set of first holes 107. The inner surface of the detection box 103 is fixedly connected to the outer surfaces of the two guide rails 206.

[0029] The effect achieved by the entire Embodiment 2 is that after the motor 201 is started, it will drive the threaded rod 202 to rotate. Under the action of the surface thread, the threaded rod 202 will drive the active block 203 to move. At this time, the slider 205 will also be driven to slide inside the guide rail 206 to prevent the active block 203 from moving in the wrong direction when moving. When the active block 203 moves, it will also drive the cleaning brush 204 to move together to clean the pollutants on the surface of the filtering device and avoid excessive pollutants from affecting the speed and effect of tail gas filtration.

[0030] Working principle: When it is necessary to detect motor vehicle exhaust gas, people can push the push rod 102. At this time, the four universal wheels 106 at the bottom will drive the detection device to move to the detection location. Subsequently, the exhaust gas is transported into the interior of the detection box 103. At this time, the high-temperature exhaust gas first contacts the first heat sink 110, and the first heat sink 110 will absorb the heat in the exhaust gas, causing the temperature of the exhaust gas to rapidly decrease. At this time, the cooling pipe 109 will transport the heat in the first heat sink 110 outward to the second heat sink 111 fixedly sleeved on its outer wall. The second heat sink 111 will dissipate the heat to the outside. After the fan 112 is started, it will accelerate the heat dissipation speed of the second heat sink 111. After the exhaust gas is cooled, the filter screen 105 will filter out the solid particles in the exhaust gas. The filtered exhaust gas continues to move forward and is detected by the detector 104. The exhaust gas after the detection is then discharged to the outside of the detection box 103. When the filter screen 105 has been used for too long, the motor 201 starts to drive the threaded rod 202 to rotate inside the detection box 103, so that the movable block 203 drives the cleaning brush 204 to move and clean the pollutants accumulated on the surface of the filter screen 105.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
