Description

Technical Field

[0001] This invention relates to the field of isolation equipment technology, and in particular to an intelligent safety barrier. Background Technology

[0002] In industrial production, automatic control requires the use of various automated instruments, control systems, and actuators. The signal transmission between them ranges from small signals as weak as millivolts or microamperes to large signals of tens of volts, or even thousands of volts or hundreds of amperes; there are low-frequency DC signals as well as high-frequency pulse signals, etc. After the system is formed, it is often found that the signal transmission between instruments and equipment interferes with each other, causing system instability or even malfunction.

[0003] A safety barrier is a device that uses linear optocoupler isolation to convert input signals into outputs. The input, output, and power supply are mutually isolated, making it particularly suitable for use with equipment and instruments requiring electrical isolation.

[0004] During use, to ensure long-term stable operation, safety barriers need to be kept within a normal temperature range (-30°C to +70°C). Existing safety barriers mainly dissipate heat by creating heat dissipation vents on the outer shell, forming a heat dissipation grille that connects the outside to the inside of the safety barrier, thus maintaining a certain heat dissipation effect. Although this method can ensure heat dissipation, because the heat dissipation grille connects the outside to the inside of the safety barrier, dust will accumulate inside the safety barrier after long-term use, which will reduce the stability and service life of the safety barrier to some extent. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an intelligent safety barrier that, while ensuring the heat dissipation effect of each safety barrier, can isolate external dust and keep the inner side of each safety barrier clean, thereby improving the stability and service life of the isolator.

Specifically, each safety barrier unit 200 includes a housing 210, with a mounting cavity 211 formed inside the housing 210, and a wiring module disposed within the mounting cavity 211. Heat dissipation grilles 212 are formed on the housing 210 and on its relatively parallel two sides. An isolation plate 220 is disposed inside the mounting cavity 211, separating the heat dissipation grilles 212 and the wiring module, forming a heat dissipation channel 250 between the isolation plate 220 and the heat dissipation grilles 212. Several insertion interfaces 221 are spaced apart on the isolation plate 220, and heat exchange components 230 are detachably disposed on the insertion interfaces 221. The mounting base 100 is provided with a blowing assembly 300 and a detection unit 400 connected to each safety barrier unit 200. The detection unit 400 acquires the temperature value within each heat dissipation channel 250 and controls the blowing assembly 300 to blow air into the heat dissipation channel 250 based on the temperature value. During operation, the partition separates the heat dissipation channel 250 from the inner wiring module, ensuring a dust-free working environment inside the housing 210. Simultaneously, the heat exchange component 230, detection component, and air blowing component 300, when low heat dissipation efficiency is detected within the heat dissipation channel, can control the air blowing component 300 to improve heat dissipation.

[0019] The heat exchange assembly 230 includes a mounting block 231 fitted into the plug interface 221. A first semiconductor pillar 232 and a second semiconductor pillar 233 are spaced apart on the inner side of the mounting block 231.

Through the first semiconductor and the second semiconductor, after power is applied, the heat inside the isolation plate 220 can be forcibly transferred to the heat dissipation channel 250. This structure can ensure that the inside of the isolation plate 220 is a dust-free environment, while simultaneously fanning heat inside.

[0020] The middle of the insertion interface 221 is integrally formed with a support plate 222, and the mounting block 231 has a first support groove 231a, into which the support plate 222 is inserted. Through the support plate 222 and the first support groove 231a, the mounting block 231 can be detachably installed, facilitating the assembly, replacement and maintenance of each heat exchange component 230.

[0021] A heat-conducting component 240 is also provided inside the connector 221.

A second support groove 241b is provided on the heat-conducting block 241, and a support plate 222 can be inserted into the second support groove 241b.

The safety barrier unit 200 has a snap-fit ​​groove 213 on both vertical sides near the mounting base 100, and the snap-fit ​​groove 213 snaps into the slot 110.

[0024] A baffle plate 216 is installed between the detection port 214 and the channel opening. The baffle plate 216 can block the incoming airflow, reducing its impact on the airflow at the detection port 214. At the same time, it ensures the effective heat dissipation of the airflow within the heat dissipation channel 250.

[0025] An air supply chamber 120 is provided inside the mounting base 100, and an air inlet 130 is provided at the bottom of the slot 110.

A control switch 320 is provided inside the air supply chamber 120. When the control switch 320 is closed, it can control the operation of the miniature fan 310.

[0026] The bottom of the slot 110 is provided with a countersunk hole 140.
