Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-7 , an embodiment of the present invention is: an early warning device for monitoring agricultural pests and diseases, including a trapping box 1, a support frame 2 is fixedly installed at the bottom of the trapping box 1, a covering top 3 is fixedly installed at the top of the trapping box 1, a trapping lamp 4 is fixedly installed at the bottom of the covering top 3, a monitoring device 5 is arranged inside the trapping box 1, and a cleaning device is arranged inside the trapping box 1; Among them, the cleaning device includes a motor 6, a reciprocating lead screw 7, a sleeve 8, a first elastic telescopic rod 9 and a scraping rod 10. The motor 6 is fixedly installed at the front of the trapping box 1, the reciprocating lead screw 7 is fixedly installed at the output end of the motor 6, the sleeve 8 is slidably installed on the surface of the reciprocating lead screw 7, the first elastic telescopic rod 9 is fixedly installed at the bottom of the sleeve 8, and the scraping rod 10 is fixedly installed at the movable end of the first elastic telescopic rod 9. By moving the scraping rod 10, the insect corpses or other impurity dust that may fall on the monitoring device 5 are cleaned, avoiding some substances from affecting the normal operation of the device, resulting in distorted or inaccurate monitoring data, and at the same time being able to avoid these pests and diseases from affecting the monitoring device, ensuring the normal operation of the device, and avoiding false alarms or missed alarms caused by external environmental factors.

[0023] The cleaning device further includes a push rod 11, a sliding rod 12, a first inclined block 13 and a shutter 14. The push rod 11 is fixedly installed at the top of the sleeve 8. The sliding rod 12 is slidably installed on the surface of the covering top 3. The first inclined block 13 is fixedly installed at the bottom of the sliding rod 12. One end of the shutter 14 is rotatably installed on the surface of the sliding rod 12, and the other end of the shutter 14 is slidably installed on the surface of the covering top 3. The scraping rod 10 contacts the monitoring device 5. The surfaces of the push rod 11 and the first inclined block 13 that contact each other are both inclined surfaces. A chute is opened on the surface of the covering top 3, and a ventilation opening is opened at the front of the trapping box 1. By contacting, it is ensured that the scraping rod 10 can clean the monitoring device 5 when moving. By setting the inclined surface, it is ensured that the push rod 11 can smoothly push the first inclined block 13 when moving. By opening the chute, it is ensured that the shutter 14 can move along a specified route.

[0024] When this embodiment works: First, set the monitoring and warning device near the farmland. At night, turn on the trapping lamp 4. The trapping lamp 4 emits a specific wavelength light source in the dark to attract insects with phototaxis. When the insects enter the inside of the trapping box 1, the monitoring device 5 analyzes the entering insects through the camera and uploads suspicious insects or data in time. When the monitoring and warning device works, the motor 6 starts to drive the reciprocating lead screw 7 to rotate. The rotation of the reciprocating lead screw 7 drives the sleeve 8 to move. The movement of the sleeve 8 drives the first elastic telescopic rod 9 to move. The movement of the first elastic telescopic rod 9 drives the scraping rod 10 to move. The movement of the scraping rod 10 cleans the insect corpses or other impurity dust that may fall on the monitoring device 5, avoiding some substances from affecting the normal operation of the device, resulting in distorted or inaccurate monitoring data. At the same time, it can avoid these pests from affecting the monitoring device, ensure the normal operation of the device, and avoid false alarms or missed alarms caused by external environmental factors. When the monitoring and warning device finishes working, the motor 6 drives the reciprocating lead screw 7 to rotate. The rotation of the reciprocating lead screw 7 drives the sleeve 8 to move. The movement of the sleeve 8 drives the push rod 11 to move. The movement of the push rod 11 contacts and pushes the first inclined block 13 to move upward. The movement of the first inclined block 13 drives the sliding rod 12 to move upward. The movement of the sliding rod 12 drives the upper part of the shutter 14 to move upward while the lower part of the shutter 14 slides inside the chute opened on the surface of the covering top 3, covering the trapping opening at the top of the trapping box 1. When the monitoring and warning device starts to work, the push rod 11 moves and no longer contacts the first inclined block 13. Subsequently, the sliding rod 12 starts to move downward under the action of gravity. The movement of the sliding rod 12 drives the shutter 14 to rotate and open the trapping opening at the top of the trapping box 1. By opening during work and closing after work, it is avoided that the sensor or the trapping opening of the monitoring and warning device is covered by spider webs, resulting in a decrease in the detection performance of the monitoring and warning device or false alarms, ensuring the normal operation of the monitoring and warning device, reducing errors caused by the obstruction of spider webs, and at the same time preventing spiders from weaving webs, which can effectively avoid damage to the surface of the device and even affect the internal parts, thereby prolonging the service life of the device.
