Technical Field
[0001] The utility model relates to the technical field of vehicle detection, in particular to an anti-freezing automobile exhaust detection device. Background Art
[0002] Since the exhaust pipe is located at the rear of the vehicle and has a multi-chamber structure inside, water vapor may condense at the exhaust pipe outlet due to the temperature difference between hot and cold.
[0003] The waiting area at the vehicle inspection site is usually located outdoors. When the waiting time is long and the outdoor temperature is low, the water vapor inside the exhaust pipe will freeze, causing the exhaust pipe to freeze, making it impossible to perform exhaust gas inspection. At present, the commonly used method of thawing the exhaust pipe is to blow hot air with a hair dryer or melt it with warm water. Additional tools are required to thaw the exhaust pipe, which is inconvenient to use and reduces the inspection efficiency.
[0004] Therefore, it is necessary to design an anti-freezing automobile exhaust detection device that can heat the exhaust pipe before automobile exhaust detection to prevent water vapor in the exhaust pipe from freezing and ensure smooth exhaust detection. Summary of the invention

[0007] The telescopic heating sleeve comprises a primary heating sleeve, a secondary heating sleeve and a heating boss. The secondary heating sleeve is arranged on the outside of the primary heating sleeve, the secondary heating sleeve is slidably connected to the primary heating sleeve, and a heating boss is arranged on the inner side of one end of the secondary heating sleeve away from the primary heating sleeve.

[0014] Figure 3 It is a schematic diagram of the grille and condensate water collection box of the utility model. DETAILED DESCRIPTION
[0015] The utility model is now further described with reference to the accompanying drawings.
[0016] See also Figure 1 , Figure 3 The utility model is an anti-freezing automobile exhaust detection device, comprising a detection device body 1, a connecting pipe 2, a pre-filter 3, a telescopic heating sleeve 4, a condensed water collecting box 5, a heating sleeve storage space 6, a heat preservation roller curtain 7, a charging device 8, and a sampling tube 10. The input end of the detection device body 1 is connected to one end of the connecting pipe 2, the other end of the connecting pipe 2 is threadedly connected to one end of the pre-filter 3, the other end of the pre-filter 3 is threadedly connected to the sampling tube 10, the outer side of the sampling tube 10 is provided with a telescopic heating sleeve 4, the sampling tube 10 is provided with a grille 101, the bottom of the grille 101 is installed with a condensed water collecting box 5, the condensed water collecting box 5 is threadedly connected to the sampling tube 10, a heating sleeve storage space 6 is provided on the side of the detection device body 1, a charging device 8 matching the telescopic heating sleeve 4 is placed inside the heating sleeve storage space 6, and a heat preservation roller curtain 7 is installed at the door of the heating sleeve storage space 6.
[0017] See also Figure 2The telescopic heating sleeve 4 includes a primary heating sleeve 41, a secondary heating sleeve 42, and a heating boss 43. The secondary heating sleeve 42 is sleeved on the outside of the primary heating sleeve 41. The secondary heating sleeve 42 is slidably connected to the primary heating sleeve 41. The heating boss 43 is provided on the inner side of one end of the secondary heating sleeve 42 away from the primary heating sleeve 41. The inner diameter of the heating boss 43 matches the outer diameter of the exhaust pipe of the detection vehicle, so as to better adhere to the exhaust pipe of the detection vehicle and heat the frozen part of the exhaust pipe.
[0018] A battery panel is provided inside the detection device body 1 . The battery panel has a charging port, and the output port of the battery panel is connected to the power supply end of the charging device 8 .
[0019] The front surface of the detection device body 1 is provided with a buckle 9 that matches the sampling tube 10. When the detection personnel carry the detection device to move, the telescopic heating sleeve 4 is removed and placed on the charging device 8 in the heating sleeve storage space 6 for charging, and the heat preservation roller curtain 7 is pulled up to avoid the situation where the outdoor temperature is too low to charge. At the same time, the sampling tube 10 can be snapped into the buckle 9 to complete the temporary fixation of the sampling tube 10, the pre-filter 3, and the connecting tube 2, which is convenient for the detection personnel to move the detection device handheld.
[0020] When the utility model is in operation, the operator removes the telescopic heating sleeve 4 from the charging device 8, installs it to the appropriate position of the end of the sampling tube 10, pulls open the telescopic heating sleeve 4, and makes the telescopic heating sleeve 4 cover the frozen part of the exhaust pipe. The telescopic heating sleeve 4 heats the frozen part of the exhaust pipe, and part of the ice melts into water and directly drips from the exhaust pipe onto the road surface, and the other part of the ice melts into water and enters the sampling tube 10. Since a condensate collecting box 5 is provided at the bottom of the sampling tube 10, the melted water will be collected in the condensate collecting box 5. If the exhaust pipe is severely frozen, the condensate collecting box 5 can be removed first, so that the water entering the sampling tube 10 will directly drip onto the road surface through the installation port of the condensate collecting box 5. After the exhaust pipe is unfrozen, the detection device body 1 can collect and detect the exhaust gas. The exhaust gas passes through the grille 101 and the pre-filter 3 in sequence and enters the detection device body 1. If there is water vapor in the exhaust gas, the water vapor will not stay in the exhaust pipe because the exhaust pipe is also provided with a telescopic heating sleeve 4. After entering the sampling tube 10 and contacting the grille 101, the water vapor will be pre-cooled and condensed into water droplets on the surface of the grille 101, and drip along the grille 101 into the condensed water collection box 5. After the exhaust gas enters the pre-filter 3 to filter out large particles of impurities, it enters the detection device body 1.
[0021] In case of extremely low temperature, the grid 101 and the sampling tube 10 are frozen, and the telescopic heating sleeve 4 can be set at the corresponding frozen position for heating.
[0022] The utility model designs an anti-freezing automobile exhaust detection device. The frozen position of the exhaust pipe can be heated by a telescopic heating sleeve. The water vapor converted after heating can pass through a condensed water collecting box to prevent the water vapor in the exhaust pipe from freezing, thereby ensuring smooth exhaust detection. The telescopic heating sleeve can be stored and charged in the heating sleeve storage space on the side of the detection device body, without the need for an external power supply, and is easy to use.
