Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical equipment, in particular to an electrical equipment fire warning device based on cloud chamber technology. Background Art
[0002] The cloud chamber technique is a physical experimental device used to observe and study the trajectory and characteristics of particles, especially for studying subprimordial particles in cosmic rays and particle physics. In the cloud chamber, a highly saturated alcohol vapor or frozen ethanol ether gas is usually filled. When a charged particle passes through these gases, ion pairs are generated, which form visible tiny droplets on their path, forming an effect called "cloud". This cloud can help observe and record particle trajectories because the movement of particles in the cloud chamber will leave obvious tracks.
[0003] The electrical equipment fire warning device is a device used to detect the risk of electrical equipment fire. Once a fire precursor phenomenon such as smoke, high temperature or flame is detected, the device will immediately trigger an alarm to notify relevant personnel to take appropriate emergency measures. The warning device can be integrated with the automatic fire extinguishing system to improve the fire extinguishing response speed and protect the safety of equipment and personnel.
[0004] In existing electrical equipment fire warning devices, smoke alarms are usually used to detect pre-fire phenomena. They emit a stable light beam through a transmitter, and a receiver receives the light beam. When there is no smoke, the light beam reaches the receiver directly. When smoke enters the beam path, the light is scattered by the smoke, and a part of the light is captured by the receiver, causing the receiver to sense the change in light and trigger an alarm. However, during use, smoke alarms require smoke to be generated, and when smoke is generated, it is not far from the fire, so it cannot predict the occurrence of a fire in advance. Utility Model Content
[0005] In order to make up for the above shortcomings, the utility model provides an electrical equipment fire warning device based on cloud chamber technology, aiming to improve the problem that the smoke alarm in the prior art requires smoke to be generated, but when smoke is generated, it is not far from the fire, so the occurrence of fire cannot be predicted in advance.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: an electrical equipment fire warning device based on cloud chamber technology, comprising a box body 1, a groove 3 is opened in the middle of the front end of the box body 1, a photoelectric sensor 4 is fixedly connected to the inner wall of the groove 3, a cloud box 5 is fixedly connected to the front side of the inner wall of the groove 3, a hole 6 is opened in the middle of the front end of the cloud box 5, a heat absorbing plate 8 is fixedly connected to the inner wall of the hole 6, a heat dissipation plate 7 is fixedly connected to the rear side of the heat absorbing plate 8, a smoke detector 9 is fixedly connected to the middle of the left side of the box body 1, a wire 10 is fixedly connected to the middle of the right side of the box body 1, a plug 11 is fixedly connected to the right side of the wire 10, and a fire extinguishing mechanism 2 is arranged on the top of the box body 1;
[0025] Specifically, electric energy is provided by the plug 11 and the wire 10. When a fire is about to occur in an electrical device, the internal temperature thereof will rise. The heat can be absorbed by the heat absorbing plate 8 and transferred to the heat dissipating plate 7, causing the temperature in the cloud box 5 to rise. The motion trajectory of such particles can be captured by the photoelectric sensor 4. By monitoring the changes in the track gauge of the particles, when the track gauge of the particles becomes faster, it means that a fire is about to occur, otherwise it is not. The monitored electrical equipment can be further monitored by the smoke detector 9 to improve the accuracy of the monitoring results.
[0026] Reference Figure 1 , Figure 2 and Figure 4 The fire extinguishing mechanism 2 includes a concave hole 201, which is opened at the rear side of the top of the box body 1. A servo motor 202 is fixedly connected to the inner wall of the concave hole 201. An air pipe 203 is fixedly connected to the rear side of the top of the box body 1. The output end of the servo motor 202 passes through the air pipe 203 and is fixedly connected to an arc-shaped baffle plate 204. The left side of the outer wall of the air pipe 203 is connected to a plurality of nozzles 205. A concentration detector 206 is fixedly connected to the top of the front end of the box body 1.
[0027] Specifically, the arc-shaped baffle plate 204 can be rotated in the air pipe 203 by starting the servo motor 202, and the air pipe 203 is connected to the external carbon dioxide gas tank. As the arc-shaped baffle plate 204 rotates, an angle in the air pipe 203 is opened to allow a large amount of carbon dioxide gas to pass through and be sprayed into the electronic equipment through the nozzle 205, thereby reducing the oxygen content inside the electronic equipment and suppressing the fire in its infancy. The oxygen concentration and carbon dioxide concentration in the electrical equipment can be detected by the concentration detector 206.
[0028] Reference Figure 1 , Figure 2 and Figure 4A fixing column 21 is fixedly connected to the right side of the bottom front end of the box body 1, and a thermometer 20 is arranged on the outside of the fixing column 21; a plurality of fixing blocks 12 are fixedly connected to the left and right sides of the box body 1; a running light 14 is fixedly connected to the right side of the top front end of the box body 1, and a fault light 13 is fixedly connected to the middle of the top front end of the box body 1; an alarm light 15 is fixedly connected to the left side of the top end of the box body 1, and an alarm horn 16 is fixedly connected to the left and right sides of the outer wall of the alarm light 15; a signal device 17 is fixedly connected to the front right side of the box body 1; a card slot 18 is fixedly connected to the left and right sides of the bottom of the box body 1, and a battery box 19 is arranged on the inner wall of the card slot 18;
[0029] Specifically, a thermometer 20 can be hung on the fixing column 21, and the ambient temperature can be known through the thermometer 20. The fixing block 12 can facilitate the device to be fixed on the electrical equipment. The operating light 14 can be used to know whether the device is operating normally. The fault light 13 can be used to remind the staff to repair the device. The alarm light 15 can be used to issue a warning in the event of a fire. The alarm horn 16 can be used to remind people of a fire. The battery box 19 can be placed in the card slot 18. The battery box 19 can provide power when the electrical equipment is powered off in the event of a fire.
[0030] Working principle: Before using the device, first, the device provides electrical energy through the plug 11 and the wire 10. When the electrical equipment is about to catch fire, the temperature inside it will rise, and the heat can be absorbed by the heat absorbing plate 8 and transferred to the heat dissipating plate 7, so that the temperature inside the cloud box 5 rises, and the charged particles in the cloud box 5 are subject to the increase of thermal motion, which makes their movement more violent. When the alcohol vapor in the cloud box 5 drives the particles to pass through, ion pairs will be generated, and these ion pairs will form visible tiny water droplets on the movement path, thus forming the so-called "cloud" effect. The photoelectric sensor 4 can capture the trajectory of such particle movement, and by monitoring the change of the particle movement track gauge, the faster the particle movement track gauge becomes, the more likely it is that a fire is about to break out. Fire occurs, otherwise it does not, and the monitored electrical equipment can be further monitored through the smoke detector 9 to improve the accuracy of the monitoring results, and through the fire extinguishing mechanism 2, when it is detected that a fire is about to occur, the arc-shaped baffle plate 204 can be rotated in the air pipe 203 by starting the servo motor 202, and the air pipe 203 is connected to the external carbon dioxide gas tank. As the arc-shaped baffle plate 204 rotates, an angle is opened in the air pipe 203, so that a large amount of carbon dioxide gas can pass through and be sprayed into the electronic equipment through the nozzle 205, thereby reducing the oxygen content inside it and curbing the fire in its infancy. The oxygen concentration and carbon dioxide concentration in the electrical equipment can be detected by the concentration detector 206 to further ensure that fire cannot occur.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
