Description

Technical Field

[0001] The present invention relates to the technical field of electrical safety monitoring, and specifically to a real-time voltage detection, control, and alarm structure for an electrician training environment. Background Art

[0002] During the electrician training process, the stability and safety of voltage are of utmost importance. Both the training equipment and students' operations have strict requirements for voltage. Any abnormal voltage fluctuations, such as overvoltage, undervoltage, or instantaneous voltage mutations, are very likely to cause irreversible damage to the training equipment and even endanger the personal safety of students in severe cases. For example, excessive voltage may cause the electronic components inside the equipment to burn out due to excessive current, while too low voltage may prevent the equipment from operating normally and affect the training process.

[0003] During the use of the real-time voltage detection, control, and alarm structure for the electrician training environment, when the voltage is too high and causes the equipment temperature to be too high, generally, after the voltage is sensed to be too high by the sensor, the power interface is directly disconnected and then the alarm device is activated to achieve the alarm effect. However, in the electrician training process, due to the complexity of the sensing device, this method cannot directly show the situation caused by the excessive voltage, thus affecting the comprehensive monitoring and alarm effect during the training process.

[0029] Among them, on the outer surface of the arc-shaped rod close to the coil, an air injection hole is provided.

[0030] The present invention has the following beneficial effects:

[0031] 1. In the present invention, after the rubber strip is heated and shrunk, the first sliding plates at both ends of the rubber strip are pushed by the first springs, causing the whole rubber strip to bend in an arc shape. Then, due to the approach of the two first sliding plates, the distance change causes the swing plate to swing upward at the end far from the first sliding plates, thereby pushing the telescopic block upward. At the same time, since the alarm senses the reduction in the distance between the two first sliding plates and gives an alarm, it is possible to reduce the situation of accidents caused by excessive voltage leading to overheating of the circuit, improving the overall safety of the device during operation and thus reducing accidents during the training with the device.

[0032] 2. In the present invention, when the two ends of the rubber strip are bent under pressure, it will drive the rectangular block in the strip-shaped groove inside the rubber strip to slide in the direction of the first sliding plate. When the rectangular block slides, it will drive the push rod to convey air into the air chamber through the intake pipe. After the staff resets the device, the second spring drives the second sliding plate to convey air out through the air outlet due to air pressure, thereby achieving the purpose of cooling the outer surface of the rubber strip and the inner wall of the coil, reducing the situation of repeated alarms due to lack of cooling, further improving the voltage detection accuracy of the device, and thus ensuring the safety of trainees during practical training.

[0033] 3. In the present invention, when the two ends of the rubber strip are squeezed and approach each other, it will drive the air chambers inside the rubber strip to approach each other. Then, when the arc-shaped rod bends, it will drive the curved rod to bend, so as to contact the inner wall of the rubber strip. In this way, when the two first arc-shaped plates approach each other and the rubber strip bends, to avoid irregular bending of the rubber strip, the bending of the arc-shaped rod and the curved rod is used to shape the bent rubber strip, ensuring the stability of cooling through gas conveyance when the device is reset, and thus achieving the purpose of cooling and protecting the coil.

[0034] 4. In the process of resetting the device by the staff, air will enter the inside of the arc-shaped rod through the air outlet by means of the second sliding plate, and then be transmitted to the inside of the curved rod from the inside of the arc-shaped rod, and finally discharged through the air holes opened on the arc-shaped rod and the curved rod, so as to achieve the purpose of uniformly cooling the surface of the rubber strip and the inner wall of the coil, thereby preventing the situation that when cooling the coil and the rubber strip, due to uneven air distribution, part of the coil is not cooled, resulting in the rubber strip continuing to soften and shrink after resetting due to heat, and further improving the effect of voltage detection accuracy.

[0035] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is a real-time detection, control and alarm structure for the voltage in an electrician training environment, including a main body 1, and further including:

[0049] An expansion mechanism 2, which is installed inside the main body 1;

[0050] An expansion mechanism 3, which is installed inside the expansion mechanism 2. By starting the operation inside the main body 1, the internal structure of the main body 1 drives the expansion mechanism 2 to start operating. During the operation of the expansion mechanism 2, it drives the expansion mechanism 3 to start operating.

[0051] The main body 1 includes a power supply 111 fixedly connected inside the main body 1. The main body 1 includes:

[0052] A fixing component 11, which is arranged inside the main body 1 through a connecting part;

[0053] A clamping component 12, which is arranged inside the main body 1 through a swinging part. After starting the power supply 111 located inside the fixing component 12, the power supply 111 drives the fixing component 11 to operate inside the main body 1. During the operation of the fixing component, it drives the clamping component 12 to start operating.

[0054] The expansion mechanism 2 includes two pushing blocks 211 arranged inside the fixed component 11. The expansion mechanism 2 includes:

[0055] A sliding component 21, which is slidably arranged inside the fixed component 11;

[0056] An air delivery component 22, which is arranged inside the fixed component 11. During the operation of the clamping component 12, it will drive the sliding component 21 located inside the fixed component 11 to start operating. During the operation of the sliding component 21, it will drive the air delivery component 22 to start operating, so as to achieve the effect of alarming when the device reaches a high temperature due to excessive voltage.

[0057] The expansion mechanism 3 includes an air chamber 311 fixedly connected inside the sliding component 21. The expansion mechanism 3 includes:

[0058] A contraction component 31, which is fixedly arranged inside the sliding component 21;

[0059] A positioning component 32, which is fixedly arranged outside the contraction component 31. During the operation of the sliding component 21, it will drive the contraction component 31 located inside it to start operating. During the operation of the contraction component 31, it will drive the 32 outside it to start operating, so as to achieve the effect of cooling the device when resetting the device.

[0060] The fixed component 11 includes a connecting pipe 112 fixedly connected to the side wall of the power supply 111. One end of the connecting pipe 112 away from the power supply 111 is fixedly connected to an operating table 113, and a connecting pipe 114 is fixedly connected to the side wall of the operating table 113;

[0061] Among them, a coil 115 is arranged at the top of the connecting pipe 114. The side wall of the power supply 111 is fixedly connected to the inner wall of the main body 1. The top of the connecting pipe 114 is fixedly connected to the side wall of the power supply 111. A rectangular groove is opened at the top of the main body 1. First, the power supply 111 inside the main body 1 is turned on. Then, after the current passes through the connecting pipe 112 and enters the operating table 113, it will continue to pass through the connecting pipe 114 and enter the coil 115. Then, when the current passing through the coil 115 is too large, the temperature of the coil 115 will rise.

[0062] The clamping component 12 includes two fixing plates 121 fixedly connected to the side wall of the main body 1. On one side of the two fixing plates 121 close to each other, a first spring 122 is fixedly connected. One end of the first spring 122 away from the fixing plate 121 is fixedly connected to a first sliding plate 123, and a swinging plate 124 is rotatably connected to the top of the first sliding plate 123;

[0063] Wherein, one end of two swing plates 124 close to each other is rotatably connected with a telescopic block 125. The inner wall of the main body 1 is fixedly connected with the side walls of two fixed plates 121. The side wall of the telescopic block 125 slides inside a rectangular groove. When the temperature of the coil 115 rises, it will synchronously drive the temperature of the rubber strip 212 to rise. When the temperature of the rubber strip 212 rises, its whole body is heated and softened. Then, since the first sliding plate 123 supported by the rubber strip 212 will be pushed by the first spring 122 to move towards the center of the coil 115 after the rubber strip 212 is softened. During the movement of the first sliding plate 123, the end of the swing plate 124 far from the first sliding plate 123 will swing upward. Then, the telescopic block 125 will move upward under the push of the swing plate 124.

[0064] The sliding assembly 21 includes a plurality of rubber strips 212 rotatably connected between two pushing blocks 211. A strip-shaped groove 213 is formed in the inner wall of the rubber strip 212, and a rectangular block 214 is slidably connected inside the strip-shaped groove 213;

[0065] Wherein, the outer surface of the pushing block 211 is fixedly connected with the inner wall of the first sliding plate 123. A plurality of air delivery grooves are formed in the inner wall of the rubber strip 212 close to the two pushing blocks 211. When the pushing block 211 moves, it will push the rubber strip 212 so that the rubber strip 212 arches in an arc shape towards the coil 115. During the bending process of the rubber strip 212, since the bending degree at the center of the rubber strip 212 is higher, the rectangular block 214 located inside the strip-shaped groove 213 will be driven by the tensile force generated by the change in distance to drive the push rod 221 to slide inside the air delivery pipe 222. During the movement of the push rod 221, it will push the gas inside the air delivery pipe 222 to move towards the inside of the air cavity 311 through the air inlet pipe 224. When the gas is sent into the air cavity 311, it will push the second sliding plate 312 to slide. Then, when the push rod 221 is reset, since one end of the air inlet pipe 224 is tapered.

[0066] The air delivery assembly 22 includes two push rods 221 fixedly connected with the inner walls of a plurality of rectangular blocks 214. One end of the push rod 221 close to the pushing block 211 is slidably connected with an air delivery pipe 222. A reset spring 223 is fixedly connected between the two push rods 221 on the side close to each other. A plurality of air inlet pipes 224 are fixedly connected to one end of the air delivery pipe 222 close to the pushing block 211.

[0067] Among them, several intake pipes 224 pass through the rubber strip 212 through the air delivery groove to the inside of the rubber strip 212. The air outlet holes at one end of the intake pipe 224 close to the rubber strip 212 are tapered. During the movement of the push rod 221, the gas inside the air delivery pipe 222 will be pushed to move inside the air cavity 311 through the intake pipe 224. When the gas is sent into the air cavity 311, the second sliding plate 312 will be pushed to slide. Then, when the push rod 221 is reset, since one end of the intake pipe 224 is tapered, only a small part of the gas inside the air cavity 311 will be absorbed when the push rod 221 absorbs the gas. Then, due to the change of the air pressure inside the air cavity 311, the second sliding plate 312 will be reset to push the gas inside the air cavity 311 to blow out through the sealing piece 314 to the outer surface of the rubber strip 212. After the device alarms through the alarm 126, the staff will reset the device by squeezing the telescopic block 125. Since the staff resets too quickly after the alarm and the coil 115 has not cooled down before resetting again, it may cause the first sliding plate 123 to contract again and alarm. Therefore, when the device resets, the gas inside the air cavity 311 will blow on the surface of the rubber strip 212 and the inner wall of the coil 115 to achieve a cooling effect, reducing the situation of repeated alarms due to lack of cooling, further improving the voltage detection accuracy of the device, and thus ensuring the safety of trainees during training. When the two ends of the rubber strip 212 are close to each other under the extrusion of the first sliding plate 123, the two air cavities 311 inside it will be driven to approach each other.

[0068] The contraction assembly 31 includes a second sliding plate 312 slidably connected to the inner wall of the air cavity 311. Two second springs 313 are fixedly connected to one side of the second sliding plate 312 close to the intake pipe 224. A sealing piece 314 is rotatably connected to one side of the air cavity 311 away from the intake pipe 224.

[0069] Among them, one side of the air cavity 311 close to the intake pipe 224 is fixedly connected to the inner wall of the rubber strip 212. An air outlet is provided on one side of the air cavity 311 away from the intake pipe 224. The outer surface of the sealing piece 314 is rotatably connected to the inside of the air outlet. When the gas inside the air cavity 311 enters the inside of the arc-shaped rod 321 through the air outlet, since the inside of the arc-shaped rod 321 and the curved rod 322 is hollow, the gas will enter the inside of the curved rod 322 synchronously during the movement. When the device is reset, since the arc-shaped rod 321 and the curved rod 322 are connected between the two air cavities 311.

[0070] The positioning assembly 32 includes an arc-shaped rod 321 fixedly connected to one side of the two air cavities 311 close to each other. A curved rod 322 is fixedly connected to the outer surface of the arc-shaped rod 321. Air outlet holes 323 are provided on the outer surface of the curved rod 322 close to the coil 115.

[0071] Among them, an air injection hole 323 is provided on the outer surface of the arc-shaped rod 321 close to the coil 115. After the two ends of the arc-shaped rod 321 approach each other, the arc-shaped rod 321 will be further bent. During the bending process of the arc-shaped rod 321, the curved rod 322 will be driven to bend synchronously. When the arc-shaped rod 321 and the curved rod 322 are bent.

[0072] During use, first, the power supply 111 inside the main body 1 is turned on. Then, the current passes through the first connecting pipe 112 and enters the operating platform 113, and then continues to pass through the second connecting pipe 114 and enters the coil 115. After that, when the current passing through the coil 115 is too large, the temperature of the coil 115 will rise. After the temperature of the coil 115 rises, since the inner wall of the coil 115 is in contact with the outer surface of the rubber strip 212, when the temperature of the coil 115 rises, the temperature of the rubber strip 212 will rise synchronously. When the temperature of the rubber strip 212 rises, its whole body is heated and softened. Then, since the first sliding plate 123 supported by the rubber strip 212 will be pushed by the first spring 122 to move towards the center of the coil 115 after the rubber strip 212 is softened. During the movement of the first sliding plate 123, the end of the swing plate 124 away from the first sliding plate 123 will swing upward. Then, when the telescopic block 125 is pushed by the swing plate 124, it will move upward. When the two first sliding plates 123 move, the alarm 126 will sense that the distance between the two swing plates 124 becomes smaller and then give an alarm. When the distance between the two 124 is adjusted by heating and softening the rubber strip 212 to give an alarm, it can reduce the accidental situation caused by excessive heat of the circuit due to too high voltage, improve the overall safety of the device during operation, and thus reduce the occurrence of accidents when using the device for training.

[0073] When the two sliding plates 123 move towards the center of the coil 115, they will synchronously push the push block 211 to move. When the push block 211 moves, it will push the rubber strip 212, causing the rubber strip 212 to arch in an arc towards the coil 115. During the bending process of the rubber strip 212, since the bending degree at the center of the rubber strip 212 is higher, the rectangular block 214 located inside the strip-shaped groove 213 will be subjected to the tensile force generated by the change in distance, driving the push rod 221 to slide into the inside of the air pipe 222. During the movement of the push rod 221, it will push the gas inside the air pipe 222 to move through the air inlet pipe 224 into the inside of the air chamber 311. When the gas is sent into the inside of the air chamber 311, it will push the second sliding plate 312 to slide. Then, when the push rod 221 is reset, since one end of the air inlet pipe 224 is tapered, only a small part of the gas inside the air chamber 311 will be absorbed when the push rod 221 absorbs the gas. Then, due to the change in the air pressure inside the air chamber 311, the second sliding plate 312 will be reset to push the gas inside the air chamber 311 to be blown to the outer surface of the rubber strip 212 through the sealing piece 314. After the device alarms through the alarm 126, the staff will reset the device by squeezing the telescopic block 125. Since the staff resets too quickly after the alarm and the coil 115 is not cooled before resetting again, it may cause the first sliding plate 123 to contract again and alarm. Therefore, when the device is reset, the gas inside the air chamber 311 will blow the surface of the rubber strip 212 and the inner wall of the coil 115 to achieve a cooling effect, reducing the situation of repeated alarms due to no temperature reduction, further improving the voltage detection accuracy of the device, and thus ensuring the safety of the trainees during practical training.

[0074] When the two ends of the rubber strip 212 are squeezed by the first sliding plate 123 and approach each other, they will drive the two air chambers 311 inside it to approach each other. Then, due to the change in the distance between the two air chambers 311, the two ends of the arc-shaped rod 321 will approach each other. After the two ends of the arc-shaped rod 321 approach each other, the arc-shaped rod 321 will be further bent. During the bending process of the arc-shaped rod 321, it will drive the curved rod 322 to bend synchronously. When the arc-shaped rod 321 and the curved rod 322 bend, they will squeeze the outside of the rubber strip 212 to achieve a supporting effect, avoiding the situation that the rubber strip 212 is irregularly bent due to being squeezed by the first sliding plate 123 after being heated and softened, enabling the rectangular block 214 located on the inner wall of the rubber strip 212 to better drive the push rod 221 to move, thus achieving the effect of ensuring the air delivery to the inside of the air chamber 311, ensuring the stability of cooling through gas delivery when the device is reset, and thus achieving the purpose of cooling and protecting the coil 115.

[0075] When the gas inside the air chamber 311 enters the inside of the arc-shaped rod 321 through the air outlet, since the inside of the arc-shaped rod 321 and the curved rod 322 is hollow, the gas will enter the inside of the curved rod 322 synchronously during the movement. When resetting the device, since the arc-shaped rod 321 and the curved rod 322 are connected between the two air chambers 311, the gas will be dispersed to the outer surface of the rubber strip 212 through the air holes 323 when the device is reset, so as to cool the overall heat-softened part of the rubber strip 212. Then, when the gas passes through the rubber strip 212 to the inner wall of the coil 115, it synchronously cools the entire inner wall of the coil 115, avoiding the uneven gas cooling caused by the air outlet being located at both ends of the rubber strip 212, further reducing the repeated alarm situation due to no cooling, improving the voltage detection accuracy of the device, and thus ensuring the safety of trainees during training.
