Description

Technical Field

[0001] This invention relates to the field of electrical fire early warning device technology, specifically to an electrical fire early warning device based on the Internet of Things. Background Technology

[0002] The Internet of Things (IoT)-based electrical fire early warning device is a system-level solution that, based on traditional electrical fire monitoring, uses sensors, communication networks, and cloud platforms to collect "electrical parameters, environmental parameters, and equipment status" in real time, perform edge computing, cloud big data analysis, and visualization. This enables early identification, graded alarm, and coordinated response to fire hazards such as short circuits, overloads, poor contacts, and leakage.

[0003] Currently, most mainstream products on the market adopt the "integrated housing + back slide rail or expansion bolt" fixing method: the back of the housing has a buckle that matches the standard 35mm DIN rail, or through holes are opened at the four corners, and the housing is locked to the inner wall of the distribution box by expansion bolts.

[0004] However, due to the limited internal space of the distribution box, the casing is surrounded by cables and copper busbars, and the clips / bolts are located between the casing and the box wall. Maintenance personnel must first disconnect the power, disconnect the wires, and then use tools to reach into the gap to release the clips or unscrew the bolts. If the clips are deformed due to long-term heat or the bolts are corroded, the casing can hardly be removed without damage, resulting in "destructive dismantling" on site, which increases maintenance time and raises the risk of secondary fire. Summary of the Invention

[0005] The purpose of this invention is to provide an electrical fire early warning device based on the Internet of Things (IoT) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixed base, wherein a connecting convex plate is provided in the middle of the surface of the fixed base, and limiting grooves are provided at the upper and lower ends of the connecting convex plate, and multiple sets of through holes are provided in the middle of the connecting convex plate, and a telescopic groove is provided at the opening of the limiting groove of the connecting convex plate, and a fixed column is elastically connected in the telescopic groove; a warning device housing, wherein a connecting groove is provided in the middle of the back of the warning device housing, and limiting inserts are provided at the upper and lower ends of the connecting groove of the warning device housing, and a fixing slot is provided on one side of the limiting insert; multiple sets of ventilation openings are provided on the back of the fixed base, and a sandwich cavity is provided inside the back of the warning device housing, and a connecting frame is provided in the sandwich cavity, and the ventilation openings are connected to a shielding plate through a connecting rod.

[0007] Preferably, bolt holes are provided at the four corners of the fixed base, and the fixed base is fixed inside the distribution box by expansion screws through the bolt holes. Upright plates are provided on both sides of the back of the fixed base, and the upright plates leave a gap between the fixed base and the inner wall of the distribution box.

[0008] Preferably, the limiting grooves provided at the upper and lower ends of the connecting groove of the early warning device housing are parallel to the limiting grooves opened at the upper and lower ends of the connecting convex plate. The limiting insert plate can be inserted into the limiting groove from the opening of the limiting groove to connect the fixed base to the early warning device housing.

[0009] Preferably, the through hole in the middle of the connecting convex plate of the fixed base is parallel to the ventilation opening on the back of the early warning device housing, and a filter screen is provided on the back of the connecting convex plate at the opening of the through hole.

[0010] Preferably, one side of the interlayer cavity opened on the back of the early warning device housing is provided with multiple sets of springs. One side of the spring is connected to the interior of the interlayer cavity, and the other side of the spring is connected to the connecting frame. The spring can drive the connecting frame to extend and retract.

[0011] Preferably, the limiting insert plate has an insertion groove on one side, and an L-shaped slide rail is provided at the bottom of the insertion groove. An L-shaped connecting plate is provided in the slide rail. One end of the L-shaped connecting plate is connected to the connecting frame in the interlayer cavity, and the other end of the L-shaped connecting plate extends out of the slide rail and into the insertion groove.

[0012] Preferably, the connecting protrusion is provided with a top holding plate in the limiting slide groove. When the limiting insert is inserted into the limiting slide groove, the top holding plate can be inserted into the insertion groove opened at one end of the limiting slide groove and held against the end of the L-shaped connecting plate in the insertion groove.

[0013] Preferably, the connecting protrusion is provided with a first spring in the telescopic groove opened in the limiting slide groove. One end of the first spring is connected to the inner wall of the telescopic groove, and the other end of the first spring is connected to a fixing post. The fixing post can be inserted into a fixing slot opened on one side of the limiting insert plate by the elastic force of the first spring.

[0014] Preferably, the bottom of the fixed column is connected to a toggle block, which extends from the extension slot opened on the outside of the telescopic groove of the connecting protrusion plate. Pressing the toggle block can cause the toggle block to drive the fixed column to retract into the telescopic groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The electrical fire early warning device based on the Internet of Things proposed in this invention, when installing the early warning device housing, firstly, the fixing base is fixed to the inner wall of the distribution box by passing expansion screws through the bolt holes at the four corners of the fixing base. Then, the limiting insert plates at the upper and lower ends of the connecting groove on the back of the early warning device housing are aligned with the limiting slide grooves at the upper and lower ends of the connecting convex plate on the surface of the fixing base, with the insertion groove on one side of the early warning device housing facing inward. Then, by pressing the actuating block, the actuating block drives the fixing column to retract into the telescopic groove, opening the opening of the limiting slide groove. Then, the limiting insert plate is slowly pushed into the limiting slide groove, connecting the fixing base to the early warning device housing. As the limiting insert plate extends, the top holding plate in the limiting slide groove begins to insert into the insertion groove on one side of the limiting insert plate. At this time, the top holding plate supports the L-shaped connecting plate extending into the insertion groove, causing the L-shaped connecting plate to drive the connecting frame to compress the spring, so that the connecting frame... The connecting rod causes the baffle plate to shift, opening the vent on the back of the warning device housing and connecting the vent to the through hole on the middle surface of the connecting convex plate. This allows the warning device housing to ventilate and dissipate heat through the through hole and the vent. When the limiting plate is fully inserted into the limiting groove, the first spring in the telescopic groove uses tension to eject the fixing post, causing it to insert into the fixing slot on one side of the limiting plate, thus fixing the warning device housing to the surface of the fixed base. When the warning device housing needs maintenance, simply press the actuating block again to retract the fixing post from the fixing slot into the telescopic groove. At this time, the spring uses tension to reset the connecting frame, causing the connecting frame to close the vent again through the baffle plate connected to the connecting rod. This prevents dust and impurities from entering the warning device housing during transport for maintenance. Then, the warning device housing can be slid off the fixed base.

The fixed base 1 is fixed to the inner wall of the distribution box by passing expansion screws through the bolt holes 2 at the four corners of the fixed base 1.

[0028] The limiting grooves 4 at the upper and lower ends of the connecting groove 13 of the early warning device housing 12 are parallel to the limiting grooves 4 at the upper and lower ends of the connecting protrusion 3. The limiting insert plate 14 can be inserted into the limiting groove 4 through the opening of the limiting groove 4 to connect the fixed base 1 to the early warning device housing 12. The through hole 5 in the middle of the connecting protrusion 3 of the fixed base 1 is parallel to the ventilation port 21 on the back of the early warning device housing 12. A filter screen is provided on the back of the connecting protrusion 3 at the opening of the through hole 5.

[0030] A first spring 8 is provided in the telescopic groove 7 opened in the limiting slide groove 4 of the connecting convex plate 3. One end of the first spring 8 is connected to the inner wall of the telescopic groove 7, and the other end of the first spring 8 is connected to the fixing post 9. The fixing post 9 can be inserted into the fixing slot 23 opened on one side of the limiting insert plate 14 by the elastic force of the first spring 8. The bottom of the fixing post 9 is connected to the actuating block 10. The actuating block 10 extends from the extension slot 11 opened on the outside of the telescopic groove 7 of the connecting convex plate 3. Pressing the actuating block 10 can cause the actuating block 10 to drive the fixing post 9 to retract into the telescopic groove 7. By pressing the actuating block 10, the actuating block 10 drives the fixing post 9 to retract into the telescopic groove 7, opening the opening of the limiting slide groove 4.

[0031] In actual use, when installing the warning device housing 12, first fix the fixing base 1 to the inner wall of the distribution box by passing expansion screws through the bolt holes 2 at the four corners of the fixing base 1. Then, align the limiting insert plates 14 at the upper and lower ends of the connecting groove 13 on the back of the warning device housing 12 with the limiting slide grooves 4 at the upper and lower ends of the connecting protrusion 3 on the surface of the fixing base 1, and make the insertion groove 15 on one side of the warning device housing 12 face inward.

When the baffle 22 shifts, it opens the vent 21 on the back of the warning device housing 12, allowing the vent 21 to communicate with the through hole 5 on the middle surface of the connecting protrusion 3. This allows the warning device housing 12 to ventilate and dissipate heat through the through hole 5 and the vent 21. After the limiting insert 14 is fully inserted into the limiting slide groove 4, the first spring 8 in the telescopic groove 7 uses tension to eject the fixing post 9, causing the fixing post 9 to insert into the fixing slot 23 on one side of the limiting insert 14, thus fixing the warning device housing 12 to the fixed base. Surface of base 1; When the warning device housing 12 is being repaired, simply press the toggle block 10 again, causing the toggle block 10 to drive the fixing column 9 to retract from the fixing slot 23 into the telescopic slot 7. At this time, the spring 19 will reset the connecting frame 20 through tension, so that the baffle plate 22 connected to the connecting rod of the connecting frame 20 will close the ventilation port 21 again, preventing dust and impurities from entering the warning device housing 12 on the way to the repair. Then, the warning device housing 12 can be slid off the fixed base 1.
