Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to a coal yard environment on-site monitoring device. Background Art

[0002] There is a large amount of coal in coal mines, thermal power plants, and cogeneration plants. To prevent coal dust from polluting the environment and coal from being contaminated by moisture, the coal is usually stored in sealed coal yards.

[0003] The environment in the coal yard is harsh. The coal mine contains a large amount of coal powder, which causes serious dust in the coal yard when transporting coal. At the same time, coal oxidation produces a large amount of harmful gases. In order to avoid safety accidents, an environmental field monitoring device is usually installed in the coal yard. The oxygen sensor, temperature sensor, methane sensor, dust concentration sensor and carbon monoxide sensor on the device are used to monitor the environment in the coal yard on site.

[0004] The existing coal yard environment on-site monitoring device needs to be used in conjunction with multiple sensors when working. The processor in the device needs to process a lot of information, so the device needs a good heat dissipation environment. The coal yard is seriously polluted by dust, which makes the dustproof net on the heat dissipation mechanism easily blocked, thereby affecting the circulation of the heat dissipation airflow and causing heat dissipation failure. In addition, the sensors on the existing coal yard environment on-site monitoring device need to be in contact with the air to monitor the oxygen concentration, temperature, methane concentration, dust concentration and carbon monoxide concentration in the air. Severe dust pollution will also cause coal powder to cover the sensor surface, reducing the contact area between the sensor and the air, thereby affecting the monitoring accuracy of the sensor. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a coal yard environment on-site monitoring device to solve the technical problem that serious dust pollution easily clogs the dustproof net and affects the accuracy of the sensor.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coal yard environment on-site monitoring device, including a device body, a vibration component is arranged on the device body, the vibration component includes a beating frame, a vibration rod is connected to the device body, a spring is connected to the vibration rod, an anti-collision sleeve is connected to the vibration rod, a dustproof component is arranged on the device body, the dustproof component includes a heat dissipation cabinet, the heat dissipation cabinet, a shielding frame is connected to the heat dissipation cabinet, a roller is connected to the shielding frame, a filter cloth is connected to the roller, and a scraper is connected to the heat dissipation cabinet.

[0007] By adopting the above technical scheme, the dustproof component is started by a rotating motor, and the output end drives a synchronous wheel to rotate, and the four rollers are rotated by the cooperation of multiple synchronous wheels and a synchronous belt. After the rollers rotate, the filter cloth circulates in the heat dissipation cabinet to take away the dust and prevent the air inlet from being blocked. After the vibration component is started by a double-head motor, the output end drives the beating frame to rotate, beat the vibration rod and then reset it. After the vibration rod is beaten by the beating frame, the shrapnel drives the vibration rod to vibrate, thereby shaking off the dust stuck on the sensor.

[0008] Furthermore, a display screen, a buzzer and a signal light are respectively installed on the device body, a sensor is connected to the vibration rod, and a control button for controlling the display screen, the buzzer, the signal light and the sensor circuit is installed on the device body.

[0009] By adopting the above technical solution, the staff presses the control button to turn on the display screen, signal light, sensor, fan and rotating motor, and at the same time starts the double-head motor intermittently. After the five sensors are started, the oxygen concentration, carbon monoxide concentration, methane concentration, dust concentration and temperature in the coal yard are monitored. When a certain value exceeds the standard, the buzzer starts to remind the staff.

[0010] Furthermore, a double-headed motor for driving the beating frame to rotate is installed on the device body, and the beating frame is movably connected to the device body.

[0011] By adopting the above technical solution, after the double-head motor is started, the output end drives the beating frame to rotate and beat the vibration rod and then reset. After the vibration rod is beaten by the beating frame, the shrapnel drives the vibration rod to vibrate, thereby shaking off the dust adhering to the sensor.

[0012] Furthermore, the vibration rods, anti-collision shields and sensors are each provided in five numbers, and the five vibration rods and the five anti-collision shields are all made of rubber material.

[0013] By adopting the above technical solution, the double-headed motor is started once at regular intervals. After the double-headed motor is started, the output end drives the beating frame to rotate and beat the vibration rod and then reset. After the vibration rod is beaten by the beating frame, the shrapnel drives the vibration rod to vibrate, thereby shaking off the dust stuck on the sensor.

[0014] Furthermore, a circular hole adapted to the sensor power line is provided on the vibration rod, and the five vibration rods, anti-collision sheaths and sensors are evenly distributed.

[0015] By adopting the above technical solution, after the vibration rod is hit by the beating frame, the shrapnel drives the vibration rod to vibrate, thereby shaking off the dust adhering to the sensor, preventing the dust from covering and affecting the monitoring accuracy of the sensor. At the same time, the anti-collision cover is set to prevent multiple sensors from colliding with each other and causing damage.

[0016] Furthermore, the heat dissipation cabinet is respectively connected to an air inlet pipe and an air outlet pipe, four fans are installed in the shielding frame, a plurality of synchronous wheels are connected to the shielding frame, a synchronous belt is connected between the plurality of synchronous wheels, and a rotating motor for driving the synchronous wheels to rotate is installed in the shielding frame.

[0017] By adopting the above technical solution, after the rotating motor is started, the output end drives a synchronous wheel to rotate, and the four rollers are rotated by the cooperation of multiple synchronous wheels and a synchronous belt. After the rollers rotate, the filter cloth circulates in the heat dissipation cabinet to take away the dust and avoid the air inlet being blocked.

[0018] Furthermore, a plurality of the rollers are provided, and a synchronous wheel is sleeved on the outside of four of the rollers.

[0019] By adopting the above technical solution, after the roller rotates, the filter cloth circulates in the heat dissipation cabinet to remove the dust and avoid the air inlet being blocked. After the filter cloth moves to the air outlet position, the air flow is backblown to blow off the dust adhering to the surface of the filter cloth.

[0020] Furthermore, the surface of the roller is rough, and a plurality of the rollers are movably connected to the shielding frame.

[0021] By adopting the above technical solution, after the rotating motor is started, the output end drives a synchronous wheel to rotate, and the four rollers are rotated by the cooperation of multiple synchronous wheels and a synchronous belt. After the rollers rotate, the filter cloth circulates in the heat dissipation cabinet to take away the dust and avoid the air inlet being blocked.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] The present invention blocks dust through the filter cloth in daily use by setting the dust-proof component. The small aperture of the filter cloth can effectively prevent dust from entering the device. After the rotary motor is started, the output end drives a synchronous wheel to rotate, and the four rollers are rotated by the cooperation of multiple synchronous wheels and a synchronous belt. After the rollers rotate, the filter cloth circulates in the heat dissipation cabinet to take away the dust and avoid the air inlet being blocked. After the filter cloth moves to the air outlet position, the airflow is backblown to blow off the dust adhering to the surface of the filter cloth, which is convenient for automatic cleaning of the filter cloth. At the same time, the scraper cooperates with the heat dissipation airflow to backblow the filter cloth surface, effectively preventing the heat dissipation mechanism from being blocked.

[0024] The present invention arranges a vibration component so that the double-headed motor starts up at regular intervals. After the double-headed motor starts up, the output end drives the beating frame to rotate, beat the vibration rod and then reset it. After the vibration rod is beaten by the beating frame, the shrapnel drives the vibration rod to vibrate, thereby shaking off the dust stuck on the sensor, preventing the dust from covering and affecting the monitoring accuracy of the sensor. At the same time, the anti-collision cover is arranged to prevent multiple sensors from colliding with each other and causing damage, effectively preventing dust from covering the sensor and affecting the measurement accuracy.

[0042] To clean the sensor 6, the double-headed motor 801 is started at regular intervals. After the double-headed motor 801 is started, the output end drives the beating frame 802 to rotate and beat the vibration rod 803 and then reset.

After the filter cloth 710 moves to the air outlet position, the hot air flow is blown back to blow off the dust adhering to the surface of the filter cloth 710, so that the filter cloth 710 can be automatically cleaned. At the same time, the scraper 711 cooperates with the hot air flow to blow back to clean the surface of the filter cloth 710. At the same time, the sensor 6 and the air outlet are not located on the same plane to avoid affecting the monitoring work of the temperature sensor 6 when the hot air flow is blown out.
