[0002] High pole lamp is the illumination device of the combination type lamp stand of the universal height of 15-40 meters, and the lighting radius can reach 60 meters, and is widely used in square, playground, airport, overpass and other places. The high pole lamp is generally of liftable type, which is composed of lamp tray, lamp pole, lifting structure and electrical control device.

[0003] The lamp tray can be lifted and lowered, and the lamp on the lamp tray can be opened and closed. The lamp tray is the main part of the daily maintenance of the high pole lamp. The opening and closing of the lighting lamp on the lamp tray and the lifting and unhooking of the lamp tray are controlled by the electrical control device.

[0004] At present, the electrical control board of the market high pole lamp is assembled by a plurality of conventional circuit components, which has the following defects and problems: the secondary control loop is complicated, the circuit board assembly is large in size, the labor cost and material cost of the primary line and the secondary line are high, the fault nodes are many, the reliability is poor, the on-site installation, operation and maintenance are not simple. There is no foolproof design, easy to misoperation, poor safety. When the lamp tray of the high pole lamp is lowered, the lamp group power circuit breaker must be closed, and the wiring of the control circuit on the lamp tray is removed. Before the lamp tray is lowered, it needs to be lifted and unhooked. If misoperation occurs, the cable may be broken or the circuit control board may be damaged, which may cause safety accidents. INVENTION CONTENTS

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and provide a control protection switch device for high pole lamp, which solves the problems of high cost, poor reliability and easy misoperation of the high pole lamp control device.

[0006] The technical scheme for solving the above technical problem is as follows: a control protection switch device for high pole lamp, comprising: a box body;

[0007] A power switch module is arranged in the box body, and the input end of the power switch module is connected with a power supply.

[0008] A relay module is arranged in the box body, and the relay module is connected to the output end of the power switch module to form a main loop. The output end of the relay module is connected with a first plug-in module, and the first plug-in module is used for connecting the lighting device or driving motor of the high pole lamp.

[0009] The single-chip microcomputer is connected with the relay module and is used for controlling on-off and switching of the relay module.

[0010] Compared with the prior art, the above technical scheme has the following beneficial effects:
