Description

Technical Field

[0001] The utility model belongs to the technical field of coal transportation, and in particular relates to a mobile coal spreading detection device with a wireless communication function. Background Art

[0002] At present, belt conveyors are important equipment in the production links of thermal power plants and coal terminals. The basic production units consisting of belt conveyors, drop hoppers and transfer stations jointly complete the basic fuel transportation tasks of thermal power plants and coal terminals.

[0003] When the fuel enters the hopper at the end of the belt conveyor, the moisture content of the coal will block the hopper, causing the coal to fall off the belt and onto the ground at the end of the belt conveyor. When a large amount of coal accumulates on the belt, it will burn out the belt motor. When cleaning a large amount of accumulated coal, the system needs to be shut down. Cleaning a large amount of accumulated coal takes a long time, resulting in reduced system reliability. Utility Model Content

[0004] The purpose of the utility model is to provide a mobile coal spill detection device with wireless communication function to solve the problem that coal spillage is not discovered in time, resulting in blockage of the hopper, accumulation of materials on the coal conveyor belt, damage to the driving motor of the coal conveyor belt, and a long time consumption in cleaning up a large amount of spilled and accumulated materials.

[0005] The utility model provides a mobile coal spill detection device with wireless communication function, comprising a mobile detection device, a coal spill detection element, an intelligent controller and a wireless communication module;

[0006] The mobile detection device is arranged on both sides of the coal conveyor belt or on both sides of the feed port of the hopper;

[0007] The mobile detection device includes a coal-fall receiving plate, a magnetic plate, a gravity plate, and a movable connecting rod;

[0008] The coal-dropping receiving plate is arranged horizontally, and its height is lower than that of the coal conveyor belt; the gravity plate is arranged vertically, and its upper end is fixedly connected to one end of the coal-dropping receiving plate, so as to utilize its own gravity to keep the coal-dropping receiving plate horizontal when there is no material;

[0009] The magnetic plate is arranged parallel to the side of the gravity plate close to the coal receiving plate; the upper end of the magnetic plate is movably connected to the coal receiving plate through the movable connecting rod;

[0010] The coal spreading detection element is provided at the lower portion of the magnetic plate and is used to detect whether the lower end of the gravity plate moves up or down;

[0011] The coal falling receiving plate is used to rotate downward with the movable connecting rod as the center when receiving the materials scattered from the coal conveyor belt, thereby driving the lower end of the gravity plate to move upward;

[0012] The coal spreading detection element is connected to the intelligent controller and is used to send the coal falling detection result of the upward movement of the lower end of the gravity plate to the intelligent controller;

[0013] The intelligent controller sends the coal falling detection result to the monitoring terminal through the wireless communication module, so that the monitoring terminal can execute the coal conveyor belt conveyor to stop running.

[0014] Furthermore, a circular magnet block is provided on the magnetic plate, and the circular magnet block is used to be adsorbed on the coal conveyor belt.

[0015] Furthermore, a waterproof and dustproof junction box is provided on the magnetic plate, and the intelligent controller and the wireless communication module are arranged in the waterproof and dustproof junction box.

[0016] Furthermore, the fallen coal receiving plate is fixedly connected to the gravity plate via a first fixing nut.

[0017] Furthermore, both ends of the movable connecting rod are connected to the falling coal receiving plate through a first fixing nut.

[0018] Furthermore, the wireless communication module adopts a Bluetooth transmission module, a WIFI transmission module or a 5G transmission module.

[0019] Furthermore, the coal spreading detection element adopts a proximity switch, a travel switch or an infrared ranging sensor.

[0020] The above solution uses a mobile, wirelessly communicating coal spill detection device. The coal spill detection element can promptly detect blockage in the hopper's feed port. The wireless communication module can then promptly send an alarm message to the monitor, who can then use the intelligent controller to stop the coal conveyor belt and take prompt cleaning measures. This prevents problems such as subsequent blockage of the hopper's feed port due to untimely cleaning, and damage to the conveyor belt's drive motor caused by large amounts of material accumulation. This ensures the operation of the coal conveyor belt system and improves its reliability. This device can be used in locations where coal spill detection is needed, such as coal conveyor belts and hopper feed ports.

The lower part is kept horizontal; the magnetic plate 3 is arranged parallel to the side of the gravity plate 2 close to the coal-dropping receiving plate 9; the upper end of the magnetic plate 3 is movably connected to the coal-dropping receiving plate 9 through a movable connecting rod 4; the coal-scattering detection element 1 is arranged at the lower part of the magnetic plate 3, and is used to detect whether the lower end of the gravity plate 2 moves up and down; the coal-dropping receiving plate 9 is used to rotate downward with the movable connecting rod 4 as the center when receiving the material scattered on the coal conveyor belt, thereby driving the lower end of the gravity plate 2 to move upward; the coal-scattering detection element 1 is connected to the intelligent controller, and is used to send the coal-dropping detection result of the upward movement of the lower end of the gravity plate 2 to the intelligent controller; the intelligent controller sends the coal-dropping detection result to the monitoring terminal through the wireless communication module, so that the monitoring terminal can execute the coal conveyor belt to stop running.

[0029] When the weight of the material on the coal-dropping receiving plate 9 is greater than the preset weight value, the coal-dropping receiving plate 9 rotates downward, and the coal-dropping receiving plate 9 drives the gravity plate 2 to move upward.
