Abstract
The utility model discloses a belt operation light alarm device, including relay KM, flashing frequency controller and lamp area L2, evenly be provided with a plurality of LED lamps on the lamp area L2. One end of the relay is connected with a starting indicator lamp L1 of the belt, the other end of the relay is connected with the input end of the flash frequency controller, and the output end of the flash frequency controller is electrically connected with the lamp strip L2. The light strip L2 is fixed on the guardrail outside the belt. Through set up the lamp area on the guardrail in the belt outside, utilize relay, contactor and stroboscopic controller, signal transmission to relay when the belt starts for relay action contactor actuation, later make to make the lamp area when the belt moves through the stroboscopic controller, last scintillation for remind the on-the-spot personnel belt to start, make people can all receive alarm information in any position, keep away from the belt, very big reinforcing the safety guarantee. The potential safety hazard caused by the fact that workers do not notice that the belt is in the running state is reduced.
Description
Technical Field
The utility model belongs to the technical field of alarm device, concretely relates to belt operation light alarm device.
Background
The coal conveying system of the thermal power plant is provided with a plurality of belts, and field workers need to be warned safely before and after the belts are started to prevent accidents. At present, used belt alarm device is alarm bell and alarm lamp's form, the early warning before starting as the belt is told, 30 seconds alarm bell before the belt starts can send out alarm bell and alarm lamp is bright simultaneously, remind personnel's belt on the spot to start, but this prerequisite is that people will listen to the alarm sound that obtains alarm bell and the alarm lamp that sees is bright, if personnel are far away or take the protection earplug far away from alarm bell, just can not in time receive alarm signal, lead to just having very big potential safety hazard among the belt start-up process.
Disclosure of Invention
In order to solve the problem, the utility model provides a belt operation light alarm device makes the alarm signal that the field work personnel can in time receive the belt and start.
In order to achieve the purpose, the utility model relates to a belt operation light alarm device, including relay KM and lamp area L2, evenly be provided with a plurality of LED lamps on the lamp area L2, the coil of relay and the start indicator L1 of belt form first return circuit, the switch of relay and lamp area L2 form the second return circuit; the light strip L2 is fixed on the guardrail outside the belt.
Further, a flash frequency controller M is arranged in the second loop, and the flash frequency controller M is used for controlling the flashing of the light strip L2.
Further, the light strip L2 is a waterproof light strip.
Further, there are two lamp strips L2, set up respectively on the guardrail of belt both sides.
Further, the lamp strip L2 is fixed on the guardrail through a hoop.
Further, the length of the light strip L2 is greater than or equal to the length of the guardrail.
Compared with the prior art, the utility model discloses following profitable technological effect has at least, the utility model discloses a set up the lamp area on the guardrail in the belt outside, utilize relay, contactor and stroboscopic controller, signal transmission to relay when the belt starts for make the lamp area when the belt moves through the stroboscopic controller after the actuation of relay action contactor, last scintillation for remind field personnel belt to start, make people can all receive alarm information in any position, keep away from the belt, very big reinforcing safety guarantee. The potential safety hazard caused by the fact that workers do not notice that the belt is in the running state is reduced.
Further, the lamp area is waterproof lamp area, and is not fragile.
Further, the length of the length more than or equal to belt in lamp area in case the staff is close to the belt, can find that the lamp area is scintillation, can learn that the belt is in the running state.
Further, the lamp strip is fixed on the guardrail through a hoop, and the lamp strip is installed or detached through the method.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the light belt of the present invention installed on both sides of the belt;
fig. 3 is a front view of the light belt of the present invention installed on both sides of the belt;
in the drawings: 1. relay, 2, LED lamp, 5, belt.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships that are based on the orientations or positional relationships shown in the drawings, and are merely for convenience in describing and simplifying the present invention, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Referring to fig. 1, a belt operation light alarm device includes relay KM, flash controller M and lamp area L2, evenly is provided with a plurality of LED lamps 2 on the lamp area L2. The coil of relay and the start indicator lamp L1 of belt form first return circuit, the switch of relay and lamp area L2 form the second return circuit, are provided with the flash controller in the second return circuit, and the flash controller is used for controlling lamp area L2 scintillation. The light strip L2 is fixed to the guard rail outside the belt 5.
Wherein, Schneider RXM4AB1FD relay is selected as the relay, and constant-signal HM-3DB flash frequency controller is selected as the flash frequency controller.
Preferably, lamp area L2 is waterproof lamp area, improves the stability of alarm device operation.
Preferably, the light strip L2 is secured to the guardrail by a plurality of clips. The clamp includes two clamp monomers, and two semicircular clamp monomer both ends all outwards stretch out and have the fixed part, set up threaded hole on the fixed part, with two bolt and screw hole threaded connection, can be in the same place two clamp monomers are fixed. When fixing lamp area L2 with the clamp, earlier put lamp area L2 on the horizontal pole of guardrail, put two clamp monomers respectively in the both sides of lamp area L2 and horizontal pole, set up screw hole threaded connection on with two bolts and the clamp monomer fixed part, make lamp area L2 and horizontal pole enclose at two clamp monomers and close the space that forms, screw up the bolt, can fix lamp area L2 on the guardrail. Referring to fig. 2 and 3, preferably, a set of light alarm devices is disposed on both sides of each belt, and when both sets of light alarm devices operate normally, the area in the middle of the two light strips L2 is the position of the belt, so that the function of dividing the area can be achieved while alarming. When one light alarm device is in fault, the other light alarm device can still work normally.
The working process of the light alarm device is as follows:
when the belt is started, the belt indicator lamp is electrified, the belt work indicator lamp is turned on, the relay gets power from the belt indicator lamp, the relay coil is attracted, the circuit is switched on, the flash frequency controller and the lamp strip L2 are electrified, and the LED lamp 2 on the lamp strip L2 starts to flash under the action of the flash frequency controller; when the belt stops operating, the belt indicator light is powered off, the relay coil is loosened, the flash frequency controller and the light strip L2 are powered off, and the light strip L2 is extinguished.
