Problems solved by technology

[0002] Because mines are generally not ventilated, workers working underground cannot breathe smoothly, so mines are equipped with ventilation systems, and fans are used to blow air into the mines to discharge excess carbon dioxide to ensure that construction workers can breathe normally. In order to make reasonable use of electric energy and at the same time ensure the normal concentration of carbon dioxide in the well, monitoring personnel are required to go to the site to monitor the carbon dioxide concentration meter in real time, and adjust the frequency converter according to the concentration of carbon dioxide to increase or decrease the fan speed to adjust the balance of carbon dioxide and oxygen. If there are many mining areas, it is impossible for monitoring personnel to patrol in real time, and the time interval between inspections of each mining area may also cause workers to lack oxygen or waste energy

Embodiment 1

[0019] Embodiment 1: as figure 1 As shown, the ventilation remote control system of the present invention includes a mine 1, a fan 2 and a frequency converter 3 are arranged in the mine 1, the fan 2 is connected to a power supply through the frequency converter 3, a carbon dioxide concentration meter 4 is provided in the mine 1, and a carbon dioxide concentration meter 4 is provided in the mine 1. The pointer shaft of the concentration meter 4 is connected to the live wire, the dial of the carbon dioxide concentration meter 4 is provided with a contact 5, a monitoring room 6 is provided, and an indicator light 7 is arranged in the monitoring room 6, and the contact 5 is connected to the neutral line through the indicator light 7. A potentiometer 8 is provided in the monitoring room 6, and the potentiometer 8 is connected to the control terminal of the frequency converter 3.

Embodiment 2

[0020] Embodiment 2: On the basis of the structure described in Embodiment 1, the dial of the carbon dioxide concentration meter 4 is provided with 3-8 contacts 5, and the contacts 5 are evenly distributed on the trajectory of the pointer tip of the carbon dioxide concentration meter 4. , and cooperate with the pointer, the number of indicator lights 7 corresponds to the number of contacts 5, each contact 5 is connected to the neutral line through an indicator light 7, and a signal amplifier 9 is provided, and the potentiometer 8 is connected to the neutral line through the signal amplifier 9 The frequency converter 3 control terminal, the number of signal amplifier 9 is 5, the wire distance between the potentiometer 8 and the signal amplifier 9, the signal amplifier 9 and the signal amplifier 9, and the signal amplifier 9 and the frequency converter 3 control terminal are all 5 meters.

Embodiment 3

[0021] Embodiment 3: On the basis of the structure described in Embodiment 2, a speaker is provided in the monitoring room 6, and the contacts 5 at the top and bottom of the dial of the carbon dioxide concentration meter 4 are connected to the indicator light 7 through the speaker.

[0022] Operation steps and working principle:

[0023] In the ventilation remote control system described above, when the carbon dioxide concentration under the mine 1 continues to increase, the pointer tip of the carbon dioxide concentration meter 4 will continuously move upwards, and multiple contacts 5 can be set, and the pointer moves to the position of each contact 5 and Contact with it will turn on the power supply of the indicator light 7 in the monitoring room 6, and the indicator light 7 will light up. The monitoring personnel can understand the approximate reading of the carbon dioxide concentration meter 4 according to the position of the contact 5 corresponding to the indicator light 7,...

Abstract

The invention provides a ventilation remote control system and belongs to the field of mine ventilation control systems. The ventilation remote control system comprises a mine, wherein a draught fan and a frequency converter are arranged in the mine, the draught fan is connected to a power supply through the frequency converter, a carbon dioxide concentration meter is arranged in the mine, a pointer rotating shaft of the carbon dioxide concentration meter is connected to a live wire, a panel of the carbon dioxide concentration meter is provided with a contact, a monitoring room is arranged, an indicator light is arranged in the monitoring room, the contact is connected to a null wire through the indicator light, a potentiometer is arranged in the monitoring room, and the potentiometer is connected to the control end of the frequency converter. In this way, work staff can conduct monitoring in the monitoring room and conduct monitoring and adjustment in real time, and therefore unbalance between carbon dioxide and oxygen in the mine can not be caused.
