Static dragging belt capable of automatically sensing wear length and alarm method thereof

Abstract

The invention provides a static dragging belt capable of automatically sensing wear length and an alarm method thereof. The static dragging belt comprises a static dragging belt body and a self-sensing circuit, one end of the bottom of the static dragging belt body is a dragging belt grounding area, and the self-sensing circuit comprises N parallel resistors R1-RN which are connected in parallel and an instrument, a wire of the grounding area of the dragging belt is provided with parallel resistors R1-RN, and the instrument is used for measuring the current total parallel resistance value R total of the parallel resistors R1-RN when the vehicle runs; the parallel resistors are sequentially arranged on the wire of the grounding area of the dragging belt from bottom to top, so that an alarm system communicating with the instrument can judge the abrasion condition of the dragging belt by comparing the received current total parallel resistance value R total with a preset value R of the parallel resistors. The static dragging belt can monitor the contact condition of the grounding belt and the ground in real time, ensures reliable grounding, and can predict the residual life of the dragging belt.

Description

technical field [0001] The invention belongs to the application field of automobile electrostatic discharge accessories, and in particular relates to a self-inductive wear-length electrostatic mop belt and an alarm method thereof. Background technique [0002] In order to improve the safety of special vehicles such as dangerous goods transport vehicles, it is required to set up static drag strips to ensure that the vehicle body is connected to the ground and eliminate possible static electricity. The electrostatic mopping belt realizes that its metal conductor is connected to the earth through its own counterweight, and the length of the mopping belt can be manually adjusted according to the wear condition, such as figure 1 As shown, the conductive rubber belt 2 with a penetrating electric wire inside is installed on the bottom of the vehicle through the fixing member and the adjusting device 1 to ensure that its length is appropriate, and the conductive rubber belt 2 is kep...

AI Technical Summary

Problems solved by technology

After the vehicle has been driving for a period of time, the mopping belt wears out, resulting in unreliable grounding, and the length of the mopping belt needs to be adjusted manually

Therefore, it is impossible to monitor the wear condition in real time. If the wear of the grounding belt is not found in time, the metal conductor of the grounding belt will not be reliably connected to the ground, resulting in the failure of static electricity to unload, and there is a risk of fire and explosion of dangerous goods.

[0006] 2. The length of the electrostatic mopping belt is manually adjusted according to the wear and tear, and manual inspection and maintenance are required. There is no intelligent detection method to predict the remaining life of the mopping belt, and timely remind customers to adjust and replace the worn electrostatic mopping belt

[0007] 3. When the contact surface between the mopping belt and the ground exceeds the normal grounding area requirement, the wear surface will increase and the service life of the mopping belt will be reduced. Therefore, there is a lack of intelligent detection means, and it is impossible to detect and warn of excessive wear caused by improper length setting of the grounding belt, etc. Problems, resulting in shortened life expectancy of the electrostatic mopping belt

[0008] Based on this, it is urgent to propose an electrostatic mopping belt and its alarm method to solve the problems of excessive wear caused by improper length setting of the electrostatic mopping belt, and issue an alarm in time to remind the driver to ensure the life and function of the electrostatic mopping belt
