Detailed Description
For a clear and complete description of the present invention, the following detailed description is made with reference to the accompanying drawings and examples.
An infrared induction coal chute coal blockage detection device is of a box body structure with a cavity and comprises a device wall 1, a movable baffle 2, a first infrared transmitting device 3, a first infrared receiving device 4 and an alarm device 5; an opening is formed in one surface, connected with the coal dropping cylinder wall 7, of the right side of the device wall 1, and corresponds to the opening of the coal dropping cylinder wall 7; the movable baffle 2 is arranged on the open surface of the device wall 1 and is connected with the device wall 1 through a rotating shaft 6 arranged at the top end of the device wall 1; the first infrared emission device 3 is connected to the top end of the inner side of the device wall 1; the first infrared receiving device 4 is connected to one side surface of the inner side of the device wall 1, which is far away from the coal dropping cylinder wall 7, and is spaced from the bottom surface of the inner side of the device wall 1 by a certain distance; the alarm device 5 is arranged outside the device wall 1 and is connected with the first infrared receiving device 4.
Example 1
The upper part of the opening of the device wall 1 is connected with the coal dropping cylinder wall 7 and the device wall 1 through an L-shaped baffle 13, and the lower part of the opening is connected with the coal dropping cylinder wall 7 and the device wall 1 through a screw 12.
The movable baffle 2 is arranged at the joint of the opening of the coal dropping cylinder wall 7 and the opening of the device wall 1, and when the movable baffle 2 is not acted by lateral force, the movable baffle is in a vertical state and shields the opening of the coal dropping cylinder wall 7 and the opening of the device wall 1. When the coal block smoothly passes through the coal dropping cylinder, the coal block cannot fall into the detection device; when the coal dropping barrel is blocked, the coal blocks are accumulated in the coal dropping barrel and extrude the wall 7 of the coal dropping barrel, so that the movable baffle 2 is subjected to lateral acting force and overturns around the rotating shaft 6, and the coal blocks enter the detection device through the gap opened by the movable baffle 2. When coal blocks entering the detection device or the movable baffle 2 which is extruded by the coal blocks, overturned leftwards and fixed in position shields the first infrared receiving device 4, and the first infrared receiving device 4 cannot receive infrared rays emitted by the first infrared emitting device 3, the alarm device 5 connected with the first infrared receiving device 4 sends out alarm sound and flashing light for reminding for 5 minutes and sends out 1-time reminding every 1 minute. The electric power worker closes the alarm device 5, dredges the coal dropping barrel, pulls the handle 9, opens the device cabin door 8 and cleans coal blocks in the detection device. After the dredging and cleaning are finished, the alarm device 5 is restarted.
The bottom surface of the device wall 1 of the detection device is a concave curved surface. When the coal briquette in the coal dropping cylinder is not blocked, but in the dropping process, individual coal briquette is collided with the movable baffle 2 to enter the detection device due to the collision among the coal briquettes, the bottom surface of the wall 1 of the detection device is a concave curved surface, and the first infrared receiving device 4 is positioned on the side surface which is away from the bottom surface of the wall 1 at a certain distance, so that the dropped coal briquette is stopped at the bottom of the concave curved surface, the first infrared receiving device 4 cannot be shielded, and meanwhile, the detection device can accommodate a plurality of coal briquettes which are mistakenly dropped into the detection device, thereby reducing the false alarm rate.
Example 2
In the premise of embodiment 1, the top end of the inner side of the device wall 1 is connected to a second infrared emitting device 10, the inner side of the device wall 1 is connected to a second infrared receiving device 11, and the horizontal position of the second infrared receiving device 11 is between the first infrared receiving device 4 and the bottom surface of the device wall 1 and is located on the side surface of the device wall 1 close to the coal dropping cylinder wall 7. When the coal blocks in the coal dropping cylinder are blocked, the coal blocks falling into the detection device or being extruded by the coal blocks, turned leftwards and fixedly arranged movable baffle plates 2 shield the second infrared receiving device 11, and the triggering alarm device 5 sends out early warning sound and flashing light reminding; when the obstruction is removed, the reminder is over.
In order to reduce the false alarm rate, the second infrared receiving device 11 sets a shielding time threshold, when the shielding time is more than 2S, the alarm device 5 is started, sends out early warning sound and flashes a lamp to remind for more than 2 minutes, and reminds once every 1 minute. When a coal block falls into the detection device by mistake, the shielding time of the falling process is below 2S, and the alarm device 5 cannot be triggered. The coal blocks which fall by mistake finally fall into the bottom of the device wall 1 with the concave curved surface and have a certain distance from the second infrared receiving device 11, and the alarm device 5 cannot be triggered.
It should be noted that the directions and positions indicated as "upper", "lower", "left", "right", "inner", "vertical", "horizontal", etc. used in the present invention are only for convenience of description and simplification of description based on the directions or positional relationships shown in the drawings, and do not indicate or imply that the indicated device or element must have a specific direction or be constructed and operated in a specific positional relationship, and thus, should not be construed as limiting the present invention.
Meanwhile, unless explicitly stated or limited otherwise, the terms "connected," "disposed," and the like are to be construed broadly and include, for example, integral or detachable connections, mechanical, component, or electrical connections. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
