Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As illustrated in fig. 1 and 2, two column are suspended on explosion-proof water barrier bracket by hook along the isolated blast water bottle of tunnel genesis analysis On 201, tunnel explosion-proof water barrier is constituted.Explosion-proof water barrier bracket 201 is fixed on back.Above-mentioned isolated blast water bottle connection type Belong to this field routine techniques.
This explosion-proof water barrier water level monitoring and automatic water-replenishing device include: water pipe, liquid level sensor, control master it is mechanical, electrical Magnet valve.As shown in Fig. 2, moisturizing branch pipe 204 is distributed in the two sides of moisturizing supervisor 205, each moisturizing branch pipe end is with water outlet Mouthful.The union elbow of moisturizing branch pipe end is located at right above isolated blast water bottle as water outlet.Moisturizing supervisor and moisturizing branch pipe 204 are attached by four-way or threeway.Solenoid valve is had on moisturizing supervisor.Preferably, solenoid valve is anti-using DFB4/16 Quick-fried electromagnetic valve for mine, for solenoid valve conventional on the market.
Liquid level sensor 301 uses universal fluid level transmitter, belongs to the conventional liquid level sensor for being easy to obtain.Work as sensing Device puts into testing liquid bottom, and sensor exports analog quantity voltage signal, carries out via the Analog input mModule that PLC is carried Signal conversion transmits electric signal to PLC.As preferred forms, sensor selects Jiangsu Huahai M & C Technology Ltd. HH319 pressure transmitter.Controller is using the control host for meeting requirement of explosion proof, and the PLC that controller KXP127 is used is west The sub- S7-200 of door does control unit, and sensor uses intrinsic safety type minute-pressure level detection sensor, and precision rate is 0.1cm.
Control host is using the control host for meeting requirement of explosion proof, preferably, control host is using Siemens S7- 200 PLC are as key control unit.Liquid level sensor 301 connect with control main frame PLC, using 4-20mA electric current between them Analog signal communication, passes the electric signal that current level is converted to back in real time.The solenoid valve of moisturizing supervisor and control main frame PLC output End series connection, then accesses the dedicated AC127V power supply in underground.
Each group of isolated blast water bottle installs one or more liquid level sensor.When multiple liquid level sensors are installed, mend Within the scope of water main line first, isolated blast water bottle is equipped with liquid level sensor immediately below the last one moisturizing branch pipe.It is intermediate every Quick-fried water bag can be installed, and can not also install and state sensor.PLC control solenoid valve opens or closes.Pipeline connecting mode are as follows: Moisturizing main line is equipped with a solenoid valve, and two sides separate and several lead to moisturizing branch right above isolated blast water bottle main line to the left and right Pipe.
As preferred forms, isolated blast water bottle inside liquid level is inaccurate in order to prevent or adds water flow different caused When liquid level difference.As shown in Figure 1, being equipped with communicating pipe in every row's isolated blast water bottle bottom, it is ensured that water supply coverage is responsible in each moisturizing Isolated blast water bottle is interconnected, and liquid level in water bag can be kept consistent.It is like that as shown in Figure 2, a connection is responsible for two sides Issue several branch pipes directly connecting with isolated blast water bottle.The water bag connector of water bag bottom is connected by union elbow with branch pipe is connected to It connects, then connection branch pipe is connected by pipe fitting with supervisor is connected to again.
It, will when any one water level sensor senses water shortage information (lower than setting value) within the scope of moisturizing supervisor's moisturizing Information is sent to control host, and control host opens water supply electromagnetic valve, carries out adding water to explosion-proof water barrier.When water adds to setting When water level, liquid level sensor sends the signal to control host, and control host control closes valve, stops adding water.
Mine explosion-suppression sink automatic water-replenishing device for underground coal mine explosion-insulating water tank water level keep, when explosion-insulating water tank water level because When overlong time declines, after liquid level sensor detects, signal is transmitted to control main frame PLC, control main frame PLC output end will Drive magnetic valve opens water supply pipe, to explosion-insulating water tank plus water;Stop supplying water when water level reaches requirement, realizes unattended water Position control.
The PLC of control host can also connect by RS485 communication interface with touch display, for real-time display every Quick-fried water bag liquid level, it is more convenient to use intuitive.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to structure of the invention Think and protection scope is defined, without departing from the design concept of the invention, ordinary engineering and technical personnel in this field To all variations and modifications that technical solution of the present invention is made, protection scope of the present invention should all be fallen into.
