AI Technical Summary
The existing detection pit lacks warning and reminder functions and ventilation systems, which may cause drivers to be unable to detect the pit in time, increasing the risk of wheel dropping. At the same time, the detection personnel are prone to adverse reactions during long-term work.
A land pit system for motor vehicle detection is designed, including ventilation system, early warning system and lighting system. The ventilation system realizes the input of fresh air and the discharge of gas through the air inlet filter and the induced fan. The early warning system uses pressure sensors and displays to sense the vehicle position and issue a warning. The lighting system provides lighting during detection through the lamp head.
The working environment of the tester is improved through the ventilation system and the adverse reactions such as chest tightness are reduced; the early warning system effectively avoids the risk of vehicle falling; and the lighting system improves the accuracy of the detection.

DETAILED DESCRIPTION
[0021] The utility model will be further described below in conjunction with the accompanying drawings.
[0022] like Figure 1-Figure 6A pit system for motor vehicle inspection shown in the figure includes a pit 1, which is covered with a carport 2, and includes a ventilation system, an early warning system and a lighting system. The ventilation system includes an air inlet filter 4, which is connected to a first induced draft fan 14, which is connected to an air outlet pipe 8 through a first buried pipe 6, and the air outlet pipe 8 is located at the bottom of the pit 1. An exhaust pipe 9 is provided on the upper part of the pit 1, and the exhaust pipe 9 is connected to a second induced draft fan 15 through a second buried pipe 7, and the second induced draft fan 15 is connected to an exhaust nozzle 16. The early warning system includes a pressure sensor 10 and a display 3, and the pressure sensor 10 is located on both sides of the pit 1. The lighting system includes a lamp holder 11, which is connected to the top of the pit 1 through a universal joint 12, and includes a controller. The first induced draft fan 14, the second induced draft fan 15, the pressure sensor 10, the display 3 and the lamp holder 11 are all controlled by the controller.
[0023] In this embodiment, the number of pressure sensors on each side is 3 rows.
[0024] In order to facilitate ventilation, ventilation holes are provided on the air outlet pipe 8 and the exhaust pipe 9.
[0025] In order to prevent cold air from entering, a heating jacket 5 is connected behind the first induced draft fan 14 , and the heating jacket 5 is sleeved on the above-ground part of the first buried pipe 6 .
[0026] In order to facilitate the control of heating, the heating jacket 5 is controlled by a controller.
[0027] In order to facilitate heating, the heating sleeve 5 is a hollow box body with a heating wire 5a arranged inside.
[0028] In order to facilitate the connection of the lamp holder, a connecting rod 13 is connected between the pit 1 and the universal joint 12 .
[0029] In order to facilitate air intake and exhaust, the air inlet filter 4 and the exhaust nozzle 16 are both arranged outside the carport 2.
[0030] The specific working process of the utility model is as follows:
[0031] When the vehicle enters, the wheels press on the pressure sensors 10, and the three rows of pressure sensors 10 all feel the pressure of the wheels. At this time, the display 3 displays "the vehicle route is normal". If the wheels deviate, they can only press on one row of pressure sensors. At this time, the display 3 warns the driver to adjust the direction or stop the car to prevent the wheels from being in the pit 1.
[0032] It should be noted that although many vehicles have different widths, the three rows of pressure sensors can still detect whether the vehicle is deviating.
[0033] During inspection, the controller is used to turn on the lamp head 11. When the staff needs to conduct a detailed inspection of a certain place, the lamp head can be adjusted through the universal joint 12 to centrally illuminate the place, thereby improving the illumination and thus improving the inspection effect.
[0034] When air intake is required, the first induced draft fan 14 inhales air, the air is filtered by the air inlet filter 4, enters through the first buried pipe 6, and is discharged from the air outlet pipe 8, so that the air enters the pit 1. When exhaust is required, the second induced draft fan 15 is turned on, and the gas in the pit 1 is discharged through the exhaust pipe 9 and the second buried pipe 7 and discharged from the exhaust nozzle 16. There is no linkage between the air intake function and the exhaust function.
[0035] When the air is cold in winter, turn on the heating 5 sets when taking in air to heat the incoming gas.
