Description

Technical Field

[0001] This utility model relates to the field of fire detection technology, specifically to a concealed fire detection and alarm device for electrical circuits. Background Technology

[0002] Electrical fire monitoring detectors are safety monitoring devices designed to address fire hazards in electrical circuits. They are used to monitor the operating status of electrical circuits in real time. A current transformer is fitted onto the wire to monitor the circuit current, and a temperature sensor is attached to the circuit to collect the temperature. The main unit receives and analyzes this data. When the parameters exceed the safety threshold, it will immediately issue an audible and visual alarm and transmit a signal to the fire protection system to prevent fires caused by circuit faults. They are widely applicable to areas with dense electrical wiring, such as distribution boxes.

[0003] In the prior art, the electrical fire monitoring detector with patent publication number CN202022737909.9 includes a housing and a base.

A circuit board is fixedly connected inside the housing, and the base is fixedly connected to the bottom of the housing. This utility model incorporates a dustproof and heat dissipation structure, including ventilation openings fixedly connected to the two side walls of the housing. A dustproof head is fixed to one end of each ventilation opening, and the ventilation openings are connected to the interior of the housing. During use, the ventilation openings allow the interior of the housing to connect with the outside, thereby increasing airflow and heat dissipation. Simultaneously, the dustproof head prevents impurities in the air from entering the interior of the housing, ensuring the normal operation of the electrical fire monitoring detector and demonstrating strong practicality. When the detector is fixed in the distribution box with bolts, holes need to be drilled in the inner wall of the distribution box in advance and bolts need to be installed. The operation process is cumbersome. In addition, when the equipment fails and needs to be repaired or replaced, the bolts need to be removed to take out the detector. In addition, the internal space of the distribution box is small, and the bolt removal and installation operation is difficult, which leads to the extension of downtime for maintenance.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example: A concealed fire detection and alarm device for electrical circuits, see attached document. Figure 1 - Appendix Figure 6The system includes a detection component 1, which includes a detector 11. A lead wire 12 is fixed to the top of the detector 11, and a probe 13 is fixed to one end of the lead wire 12. The detector 11 is used to receive the temperature signal transmitted by the probe 13, collect and analyze the temperature parameters of the electrical circuit, and trigger an alarm and transmit a signal when the parameter exceeds the safety threshold, so as to realize the monitoring of fire hazards in the electrical circuit. The lead wire 12 is a signal transmission and physical connection component, used to stably transmit the temperature signal collected by the probe 13 to the detector 11. The probe 13 is a temperature sensing component, which is attached to the heat-prone parts of the electrical circuit, collects the circuit temperature data in real time, and transmits the data to the detector 11 through the lead wire 12.

[0021] Mounting component 2, which is mounted on detector 11, includes mounting part 21. Mounting part 21 includes clamping plate 211, which is located on one side of detector 11. A frame 212 is provided on the top of detector 11, and a movable plate 213 is provided on one side of frame 212.

[0022] The detector 11 is usually installed inside a distribution cabinet. A guide rail is installed inside the cabinet. First, the movable plate 213 is moved, which moves the clamping plate 211, increasing the distance between the two clamping plates 211. Simultaneously, the distance between the two clamping frames 212 also increases. At this point, one end of the lead wire 12 can be inserted into the top of the detector 11. Then, the clamping plate 211 is clamped onto the guide rail of the distribution cabinet. The detector 11 is then moved to the designated position according to usage requirements. During this process, the clamping plate 211 can slide along the guide rail. After moving to the designated position, the movable plate 213 returns to its original position. The clamping plate 211 then clamps the guide rail, fixing the position of the detector 11. Simultaneously, the clamping frames 212 clamp the lead wire 12, securing the connection between the lead wire 12 and the detector 11, thus preventing the lead wire 12 from falling off.

[0023] Specifically, the installation component 2 also includes a movable component 22, which includes a hinge rod 221. The hinge rod 221 is hinged to one side of the clamping plate 211, and a positioning frame 222 is hinged to one end of the hinge rod 221. The positioning frame 222 is fixed to one side of the detector 11.

[0024] The clamping plate 211 is movably connected to the positioning frame 222. The positioning frame 222 can support the clamping plate 211 and the hinge rod 221 to prevent them from shifting when moving. When the clamping plate 211 moves, it can drive the hinge rod 221 to move. At this time, the clamping plate 211 can be supported by the hinge rod 221.

[0025] Furthermore, a drive rod 223 is hinged to one side of the hinge rod 221, and a movable plate 224 is fixed to one side of the drive rod 223. The movable plate 224 is slidably connected to one side of the positioning frame 222.

[0026] Moving the movable plate 224 can drive the drive rod 223 to move, and then moving the drive rod 223 can drive the hinge rod 221 to move. At this time, moving the hinge rod 221 can drive the clamping plate 211 to move.

[0027] Preferably, a pressing rod 225 is hinged to one side of the movable plate 224, a connecting plate 226 is hinged to one end of the pressing rod 225, a movable column 227 is fixed to one side of the connecting plate 226, and the movable column 227 is movably connected to the positioning frame 222.

[0028] The movement of the movable column 227 can drive the connecting plate 226 to move. When the connecting plate 226 moves, it can drive the two pressing rods 225 to move. The movement of the pressing rods 225 can drive the two movable plates 224 to move towards each other. The movement of the movable plates 224 can drive the drive rod 223 to move.

[0029] It should be noted that the mounting assembly 2 also includes a locking component 23, which includes a connecting rod 231. The connecting rod 231 is hinged to one side of the frame 212, and a support box 232 is rotatably connected to the outside of the connecting rod 231. The support box 232 is fixed to the top of the detector 11.

[0030] The movement of the connecting rod 231 can move the clamping frame 212, thereby clamping one end of the lead wire 12 to prevent the connection between the lead wire 12 and the detector 11 from becoming loose. The support box 232 is used to support the connecting rod 231 to prevent the connecting rod 231 from shifting. A sealing ring is fixed on the inner wall of the support box 232. A groove corresponding to the sealing ring is opened on the connector at one end of the lead wire 12. After connecting one end of the lead wire 12 to the support box 232, the lead wire 12 can be engaged with the connector on the top of the detector 11. At this time, the groove on the connector at one end of the lead wire 12 can squeeze the sealing ring, thereby maintaining the sealing during connection.

[0031] Furthermore, a pusher 233 is provided at one end of the connecting rod 231, and a connecting column 234 is fixed on one side of the pusher 233. The connecting column 234 is fixed to one end of the movable column 227, and the movable plate 213 is fixed to one side of the connecting column 234.

[0032] One end of the connecting rod 231 is fixed with a guide strip. A pressing groove corresponding to the guide strip is opened on the push frame 233. When the connecting column 234 is moved, the push frame 233 can be moved. At this time, the push frame 233 can drive the pressing groove to press the guide strip, thereby making the connecting rod 231 move. The movement of the connecting rod 231 can drive the frame 212 to move.

[0033] Specifically, a limiting plate 235 is provided below the movable plate 213, and a movable strip 236 is fixed on the top of the limiting plate 235. The movable strip 236 is movably connected to the movable plate 213.

[0034] A limiting groove corresponding to the limiting plate 235 is provided on the top of the detector 11. When the moving plate 213 is moved, the clamping plate 211 clamps the guide rail, and at the same time, the clamping frame 212 clamps one end of the lead wire 12. Then, by engaging the limiting plate 235 with the limiting groove, the moving plate 213 can be limited. When it is necessary to release the limitation of the moving plate 213, the limiting plate 235 can be separated from the limiting groove by moving the moving bar 236, thereby releasing the limitation of the moving plate 213, and the user can then move the moving plate 213.

[0035] Preferably, a pressure plate 237 is sleeved on the outer side of the moving strip 236, and a first spring 238 is fixed on the top of the pressure plate 237. The first spring 238 is fixed to the inner wall of the moving plate 213.

[0036] When the moving bar 236 moves and causes the limiting plate 235 to separate from the limiting groove, the pressure plate 237 can be moved. The movement of the pressure plate 237 applies a squeezing force to the first spring 238, thereby releasing the limitation on the moving plate 213. Then, the moving plate 213 is moved to the designated position, and the moving bar 236 is released. The rebound force of the first spring 238 can drive the limiting plate 235 back to its original position and re-engage with the limiting groove, thereby limiting the moving plate 213 again.

[0037] When using a concealed fire detection and alarm device, first press the moving bar 236 to drive the pressure plate 237 to compress the first spring 238, and the limit plate 235 will disengage from the limit groove at the top of the detector 11, releasing the fixation of the moving plate 213. Then push the moving plate 213 to drive the connecting column 234 and the movable column 227 to move synchronously.

[0038] The movable column 227 drives the connecting plate 226 to move, the connecting plate 226 pulls the pressing rod 225, the pressing rod 225 pushes the two movable plates 224 to slide towards each other along the positioning frame 222, the movable plate 224 drives the drive rod 223 to rotate, the drive rod 223 pulls the hinge rod 221, so that the distance between the two clamping plates 211 is expanded. At the same time, the connecting column 234 drives the push frame 233 to move, the push frame 233 presses the guide strip of the connecting rod 231 through the pressing groove, drives the connecting rod 231 to rotate, and the distance between the two clamping frames 212 expands synchronously.

[0039] Then, align the clamp 211 on one side of the detector 11 with the slide rail inside the distribution box and insert it. Slide the detector 11 along the slide rail to the monitoring position corresponding to the part of the electrical circuit that is prone to overheating. No drilling or fixing bolts are required, simplifying the installation process. Then, insert one end of the lead wire 12 into the connector on the top of the detector 11. The sealing ring on the inner wall of the support box 232 fits into the groove of the lead wire 12 connector to ensure a tight connection.

[0040] Then, the moving plate 213 is pushed in the opposite direction, which drives the connecting column 234 and the movable column 227 to reset. The movable plate 224, the drive rod 223, and the hinge rod 221 move to make the clamping plate 211 clamp the slide rail and fix the position of the detector 11. At the same time, the pusher 233 drives the connecting rod 231 to rotate, and the clamping frame 212 clamps the lead wire 12 to prevent the lead wire 12 from being loosened or falling off due to vibration or pulling, thus ensuring stable transmission of temperature signals.

[0041] Then, the moving bar 236 is released, the first spring 238 rebounds and drives the pressure plate 237 to reset, so that the limit plate 235 is inserted into the limit groove, fixing the moving plate 213 and ensuring that the installation structure is stable. The probe 13 is then attached to the part of the electrical circuit that is prone to overheating, completing the detection layout.

[0042] When the equipment is working, the probe 13 collects the line temperature data in real time and transmits it to the detector 11 through the lead wire 12. The detector 11 analyzes the data and triggers an alarm and transmits a signal when the parameter exceeds the safety threshold. When maintenance or replacement is required later, the detector 11 can be quickly removed by moving the moving bar 236 and pushing the moving plate 213, which is suitable for the narrow space of the distribution box and shortens the maintenance time.

[0043] In summary, the detector 11 can be quickly fixed to the slide rail inside the distribution box without drilling holes for fixing bolts, simplifying the installation process. Subsequent maintenance and replacement can be carried out quickly without removing bolts, making it suitable for narrow spaces, reducing the difficulty of disassembly and assembly, shortening maintenance time, and allowing for flexible adjustment on the slide rail without disassembly and reassembly, thus improving installation adaptability.

[0044] The connection between the lead wire 12 and the detector 11 can be fixed to prevent the lead wire 12 from becoming loose or falling off due to vibrations from the operation of equipment in the distribution box and pulling of wiring, thus ensuring stable transmission of temperature signals and preventing monitoring interruption.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
