Description

Technical Field

[0001] The invention belongs to the technical field of temperature detection, and in particular relates to a surface temperature detection device for an electric heater used in a motor vehicle group. Background Art

[0002] In modern EMUs, electric heaters are widely used for temperature regulation in carriages and to ensure passenger comfort. In order to ensure the normal operation and safety of electric heaters, real-time monitoring of their surface temperature is crucial.

[0003] The electric heater is usually installed inside the air outlet of the EMU to heat the blown air when it is discharged. However, the prior art requires a worker to insert an infrared temperature sensor from the air outlet to detect the surface temperature of the electric heater so that the infrared rays emitted by the infrared temperature sensor are irradiated on the surface of the electric heater to detect the surface temperature of the electric heater. This detection method has complicated operation steps, which affects the efficiency of detecting the surface temperature of the electric heater. In addition, since the EMU air outlet is internally circulated, dust in the car is easy to adhere to the surface of the heating rod of the electric heater when air is discharged from the air outlet. When the infrared temperature sensor is used for detection, the adhered dust will absorb and scatter infrared radiation, which will cause the amount of radiation received by the sensor to be reduced or distorted, thereby affecting the accuracy of temperature measurement and reducing the reliability of detection.

The side walls of the other ends of the connecting plates 132 are provided with a fourth groove 134. The inner wall of the fourth groove 134 is fixedly connected to the first motor 135. The output end of the first motor 135 passes through the side wall of the connecting plate 132 and is fixedly connected to one end of the third electric telescopic rod 133. The telescopic ends of the third electric telescopic rod 133 are fixed with detection plates 136.

[0036] The side wall of the detection plate 136 is provided with a plurality of fifth grooves 137, the inner walls of the fifth grooves 137 are rotatably connected with a rotating rod 138, the rod wall of the rotating rod 138 is fixedly connected with a dust sticking rod 139, the top side wall of the detection plate 136 is fixedly connected with a plurality of second motors 1310, the output ends of the plurality of second motors 1310 all pass through the side wall of the detection plate 136 and are fixedly connected with one end of the rotating rod 138, the side wall of the detection plate 136 is fixedly connected with a plurality of second infrared temperature sensors 1311, the angle at which the second infrared temperature sensor 1311 is set enables the infrared rays emitted by the second infrared temperature sensor 1311 to irradiate the position where the adjacent dust sticking rod 139 contacts the heating rod.

[0037] Specifically, the electric heater surface temperature detection component 12 and the two side surface temperature detection components 13 can be used to clean the dust adhered to the front and rear outer walls and the surface of the two end side walls of the heating rod of the electric heater body 1, so as to prevent the adhered dust from absorbing and scattering infrared radiation, resulting in a reduction or distortion of the amount of radiation received by the sensor, thereby affecting the accuracy of temperature measurement, and improving the reliability and accuracy of the surface temperature detection of the electric heater body 1. After cleaning the dust adhered to the surface of the heating rod, it will help the electric heater body 1 to effectively heat the air at the air outlet, thereby improving the use effect of the electric heater body 1.

[0039] Specifically, when the surface temperature of the electric heater body 1 is detected, the second air pump 16 is controlled to start and air is injected into the pneumatic telescopic shell 15, so that the pneumatic telescopic shell 15 is extended outward to block the wind blown out of the air outlet, thereby preventing the scraper 128 from scraping off the dust on the surface of the heating rod and being blown out of the air outlet by the wind. At the same time, when the arc plate 126 moves, when the pressure sensor 14 detects the pressure, it means that the arc plate 126 moves to the position where the electric heater body 1 fixes the heating rod. At this time, the second electric telescopic rod 125 is controlled to contract, driving the arc plate 126 to move, and avoiding the fixed position of the heating rod. After that, as the arc plate 126 moves and passes the fixed position of the heating rod, the second electric telescopic rod 125 is controlled to start, so that the scraper 128 contacts the outer wall of the heating rod again, thereby preventing the fixed position of the electric heater body 1 on the heating rod from affecting the movement of the arc plate 126.

[0040] The operating principle of the present invention is now described as follows:

[0041] In the present invention, when it is necessary to detect the surface temperature of the electric heater body 1, the first base plate 2 and the second base plate 3 are first installed on both sides of the electric heater body 1 by using the mounting bolts 5, and at the same time, it is ensured that the position of the second base plate 3 is located at the air inlet of the electric heater body 1, and then the first electric telescopic rod 123 is first controlled to start, so that the fixing plate 124 drives the second electric telescopic rod 125 to move, so that the positions of the plurality of arc plates 126 correspond to the positions of the heating rods on the corresponding electric heater body 1, and then the second electric telescopic rod 125 is controlled to start, so that the arc plates 126 are driven to move toward the direction of the electric heater body 1, so that the side wall of the scraper 128 contacts the outer side wall of the heating rod of the electric heater body 1, and then the first electric slide rail 7 and the second electric slide rail 10 are controlled to start, so as to drive the first slide plate 8 and the second slide plate 11 to move, so that the scraper 128 continuously moves on the outer side wall of the heating rod, and in the process of the scraper 128 moving, the dust adhered to the outer side wall of the heating rod can be scraped off, and then the first electric slide rail 7 and the second electric slide rail 10 are controlled to start, so as to drive the first slide plate 8 and the second slide plate 11 to move, and then the first electric slide rail 7 and the second electric slide rail 10 are controlled to start, so as to drive the first slide plate 8 and the second slide plate 11 to move, and then the scraper 128 continuously moves on the outer side wall of the heating rod, and in the process of the scraper 128 moving, the dust adhered to the outer side wall of the heating rod can be scraped off, and then the first electric slide rail 7 and the second electric slide rail 10 are controlled to start, so as to drive the first slide plate 8 and the When the first electric slide rail 7 and the second electric slide rail 10 are started, the first air pump 1212 is controlled to start, and the air in the storage shell 1211 is continuously pumped out, and the air inlet pipe 1210 pumps the outside air into the connecting shell 129 through the spring hose 1213 and the connecting shell 129. In this process, the dust scraped off the outer wall of the heating rod will be sucked into the connecting shell 129 by the air inlet pipe 1210, and then enter the storage shell 1211 through the spring hose 1213, so as to complete the collection of the dust adhering to the surface of the heating rod. After that, the first infrared temperature sensor 127 is controlled to start, so that the infrared rays emitted by the first infrared temperature sensor 127 are irradiated on the outer wall of the heating rod of the electric heater body 1 after being cleaned by the scraper 128, so as to measure the temperature of the outer side of the heating rod of the electric heater body 1. With the movement of the first slide plate 8 and the second slide plate 11, the first infrared temperature sensor 127 can be used to uniformly detect the surface temperature of the front and rear sides of the electric heater.

[0042] While detecting the surface temperatures of the front and rear sides of the electric heater body 1, the plurality of first motors 135 are controlled to start, driving the third electric telescopic rod 133 to rotate, so that the inclination angle of the detection plate 136 corresponds to the inclination angle of the heating rod of the electric heater body 1, and then the third electric telescopic rod 133 is controlled to start, driving the detection plate 136 to move toward the side walls of both ends of the heating rod of the electric heater body 1, and after the dust sticking rod 139 contacts the outer wall of the heating rod of the electric heater body 1, the third electric telescopic rod 133 is controlled to stop extending, and then the second motor 1310 is controlled to start, driving the corresponding rotating rod 138 to rotate, thereby driving the dust sticking rod 139 to rotate, thereby removing the dust adhered to the outer wall of the heating rod, and then the third electric telescopic rod 133 is controlled to shrink a certain distance, so that the position where the dust sticking rod 139 contacts the heating rod is exposed, and then the second infrared temperature sensor 1311 is controlled to start, and the dust sticking rod 139 cleans the outer wall of the heating rod. The surface temperature of the rear position can be detected, and the first base plate 2 and the second base plate 3 can be installed on both sides of the electric heater body 1, which is convenient for real-time detection of the surface temperature of the electric heater body 1, avoiding the staff from using a handheld detection device to detect the surface temperature of the electric heater, thereby improving the detection efficiency of the electric heater body 1, and at the same time, the electric heater surface temperature detection component 12 and the two-side surface temperature detection components 13 can be used to clean the dust adhered to the front and rear outer walls and the surface of the two end walls of the heating rod of the electric heater body 1 to prevent the adhered dust from absorbing and scattering infrared radiation, resulting in a reduction or distortion of the radiation received by the sensor, affecting the accuracy of temperature measurement, and improving the reliability and accuracy of the surface temperature detection of the electric heater body 1. After cleaning the dust adhered to the surface of the heating rod, it helps the electric heater body 1 to better effectively heat the air at the outlet, thereby improving the use effect of the electric heater body 1.
