Abstract
The utility model relates to an over-temperature water gushing device for underwell belt conveyers, which is a safety protection device for mines. The utility model comprises a hot melt pipe of the eutectic temperature sensing material made of the paraffin mixture, drag ropes, a pulley wheel, a weight dropper, a spherical automatic water discharge valve, a water supply pipe, a gauze filter, a nozzle and an over temperature automatic power cut switch, wherein, the hot melt pipe and the nozzle are arranged at the position which is fast in temperature rise and easy in firing. By using the paraffin mixture to make the eutectic temperature sensing material, the device has reasonable design, low cost, easily obtained material, stable performance, and good effect of sensing temperature and gushing water, which can automatically cut power when over temperature occurs. The utility model is a favorable automatic fire protecting and extinguishing device for underwell belt conveyers.
Description
The utility model relates to a kind of mine safety protector, further is the anti-extinguishing device of down-hole rubber conveyer.
At present, the rubber conveyer overtemperature water injector that adopts under the coal mine, or claim anti-extinguishing device, mainly form by fusible alloy rod, haulage cable, pulley, weight, automatic drain valve, nozzle etc.The fusible alloy rod is meltable temperature-sensing element.When down-hole ambient temperature reached the fusing point of fusible alloy, the fusible alloy rod was broken by haulage cable by weight, and automatic drain valve is opened, the nozzle sprinkling fire.The anti-extinguishing device of this pattern all has employing in Britain, China.In this anti-extinguishing device, the used fusible alloy of fusible alloy rod is to make key, and it is formulated by multiple rare metal, the manufacturing cost height.In addition, this device automatic water jetting valve is the template valve, move easy to failure, no overtemperature automatic circuit break function, fusible alloy rod and nozzle riding position be not on the most fire-hazardous position.In addition, also have dry-powder-type to prevent extinguishing device in the Soviet Union, but different with the former.
Purpose of design of the present utility model is to avoid above-mentioned weak point of the prior art, and a kind of material is easy to get, meltable temperature sensing material and element with low cost and provide.The automatic water jetting valve is improved, increased the overtemperature automatic circuit break function, fusible alloy rod and nozzle riding position reasonable Arrangement.
The purpose of this utility model can reach by following measure: in the down-hole rubber conveyer overtemperature water injector of being made up of meltable temperature-sensing element, haulage cable, pulley, weight, automatic drain valve, supply channel, nozzle, meltable temperature-sensing element adopts tempreature bulb, and tempreature bulb has the paraffin wax mixture temperature sensing material of casting between body, the tube core in body and body, the tube core to constitute.
The purpose of this utility model can also reach by following measure:
The automatic drain valve of this device adopts spherical valve.
The weight of this device is associated with and makes the rubber conveyer overtemperature cut-off switch of outage automatically.
Tempreature bulb is arranged near the position in the middle of two head rolls.
The nozzle installation site is the belt both sides about close head roll both sides and head, divide two-layer layout.
The utility model compared with prior art has following advantage:
1. the tempreature bulb cryogenic property is stable, reliable in action, and material therefor is easy to get, with low cost.
2. automatic drain valve changes spherical valve into, and volume is little, and is in light weight, and it is reliable to be active in one's movements.
3. the overtemperature automatic power-off switch is set, can cuts off the power supply of rubber conveyer when overtemperature, the accident of preventing spreads.
4. tempreature bulb is arranged near the position in the middle of two head rolls, and promptly the fastest position of temperature rise is provided with rationally the temperature-sensitive sensitivity.
5. the nozzle installation site is provided with rationally, promptly at the high temperature fire position.
6. be installed in the supply channel on the rubber conveyer headstock, simple in structure, easy for installation, not limited by the tunnel.
7. install gauze filter in the supply channel, filter, can guarantee the water spray effect supplying water.
The drawing of accompanying drawing is described as follows:
Fig. 1: each arrangements of components schematic diagram of the utility model
Fig. 2: tempreature bulb structural representation
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1: install in tempreature bulb 1, walk around pulley 3 by weight 4 tensioners by haulage cable 2 near rubber conveyer two head roll middle parts.From the pressure water source of a ground or a last level,, arrive automatic drain valve 5 through supply channel 8, gauze filter 6.Automatic drain valve 5 is controlled through valve rod 7 by weight 4.
Under the normal condition, automatic drain valve 5 is closed, and the water route is obstructed, and nozzle 9 is not sprayed water.When rubber conveyer generation stall or other reasons, making head roll transfer belt does not change when causing violent friction to produce high temperature, be arranged near temperature after tempreature bulb 1 thermal radiation of two head roll middle parts and raise, in reaching it during the fusing point of paraffin wax mixture temperature sensing material 12, body 11 and tube core 13 will be pulled steel wire rope 2 and draw back, and will drop by the weight 4 that haulage cable 2 is sling, drive valve rod 7 and rotate 90 °, open automatic drain valve 5, ten nozzles 9 that make the current in the supply channel 8 divide two-way to pass through the two-layer layout of branch are concentrated water spray in the high temperature dot place of two-layer belt up and down to two head roll both sides and chain-drive section, the cooling fire extinguishing.Simultaneously, the automatic power-off switch 10 that is being joined by weight will draw back outage, cut off the power supply of rubber conveyer, make it stall.Prevent expanding of fire incident.
Fig. 2 illustrates the structure of tempreature bulb.It is made up of body 11, tube core 13, gland 15, shelves pad 14, paraffin wax mixture temperature sensing material 12.Body 11 materials can preferentially be selected aluminium, copper material for use, and steel also can.The size of body 11 can be: φ 30 * 180mm.To select the disconnected temperature of hot melt for use be 50 ± 3 ℃, when fixedly pulling force is the 100N left and right sides, the component content of the meltable temperature sensing material of paraffin wax mixture can be: paraffin wax 92%, civilian cured 8%.Adjust content ratio, can change the disconnected temperature of hot melt.
Cut-off switch 10 is selected the single button flame-proof switch of LA81 type for use, and is changed a social system.Method for remanufacturing: on the button of this switch, bore a radial hole, insert a thin iron rod in the hole, button is blocked, make this switch be in on-position, one end of thin iron rod is with holes and fasten with seizing wire and weight 4 and link, and when weight 4 tenesmus, carefully iron rod is drawn out, button rebounds, and switch will change disconnection into by connection.
