Description

Technical Field

[0001] This invention relates to the field of electrical engineering cable laying technology, specifically to a quick-installation cable tray fire protection device and method with integrated intelligent temperature detection. Background Technology

[0002] In modern complex buildings, cable trays, as key facilities for carrying and protecting cables, face significant challenges in installation and maintenance. Traditionally, cable trays are mechanically connected using connecting plates, bolts, and nuts. This method is not only time-consuming and labor-intensive to install, especially difficult when working at heights or in confined spaces, but also prone to problems such as loose bolts, corrosion, or even missing bolts during use. This leads to insecure connections, increased contact resistance, and consequently, localized overheating, becoming a high-risk hazard for electrical fires.

[0003] On the other hand, existing cable tray systems generally lack the ability to sense the temperature of connection points in real time. Although some solutions attempt to add external temperature sensors, they have obvious technical defects: the sensors are usually fixed to the outer wall of the cable tray, which can only indirectly reflect the ambient temperature and cannot accurately capture hot spots inside the connection point caused by poor contact or concentrated current. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-installation cable tray fire protection device with integrated intelligent temperature detection. It connects a first cable tray and a second cable tray via quick-installation splicing modules. Each quick-installation splicing module consists of a male interface component and a female interface component. The male interface component has a plug and a first insertion hole, while the female interface component has a slot and a second insertion hole. The slot has an elastic buckle with a locking block on its outer side. After the plug is inserted into the slot, the locking block passes through the second insertion hole and locks with the first insertion hole. Simultaneously, a temperature sensing strip is embedded in a groove on the inner wall of the top port of the cable tray, and a microprocessor unit, a wireless communication unit, a power supply unit, and an audible and visual alarm module are integrated. This achieves boltless quick-installation connection, close-range temperature detection, and tiered early warning alarms, solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-installation cable tray fire protection device with integrated intelligent temperature detection includes a first cable tray and a second cable tray. The connection between the first cable tray and the second cable tray is connected by a quick-installation splicing module. There are two sets of quick-installation splicing modules, which are located on both sides of the first cable tray and the second cable tray respectively. Each set of quick-installation splicing modules includes a male interface component and a female interface component.

[0007] The male interface component includes a first connecting block and a plug block. The first connecting block is fixed to the port side wall of the first cable tray, and the end of the plug block is fixedly connected to the middle position of the first connecting block. The plug block has a first plug hole.

[0008] The female interface assembly includes a second connecting block and a slot block. The second connecting block is fixed to the port side wall of the second cable tray. The end of the slot block is fixedly connected to the middle position of the second connecting block. The slot block has a slot on the side facing the plug block. A second plug hole is opened on the outer side wall of the slot block. After the plug block is fully inserted into the slot, the second plug hole is aligned with the first plug hole and their axes coincide. An elastic buckle is also provided on the outer side of the slot block. A locking block is provided on the inner side of the elastic buckle. The locking block passes through the second plug hole and the first plug hole.

[0009] A monitoring element box is also provided on one side of the first cable tray or the second cable tray. The monitoring element box contains an intelligent monitoring module. The intelligent monitoring module includes a temperature sensing strip and a microprocessor unit. The temperature sensing strip is embedded in the inner wall groove of the top port of the first cable tray and the second cable tray. The temperature sensing strip and the microprocessor unit for receiving and processing the temperature sensing strip data and performing logical judgments are electrically connected.

[0010] Preferably, the insert block is horizontally arranged, and the slot block is horizontally arranged and horizontally aligned with the insert block.

[0011] Preferably, the outer edge of the slot is also provided with a guide slope.

[0012] Preferably, the inner wall of the slot is provided with a sealing strip, and the sealing strip is squeezed and adhered when the insert and the slot are spliced ​​together.

[0013] Preferably, the elastic buckle and the second cable tray are provided with rotating support blocks on opposite sides, and the rotating support blocks are connected by a central pivot. A torsion spring is provided on the central pivot, and the two spring arms of the torsion spring are fixedly connected to the sides of the second cable tray and the elastic buckle, respectively.

[0014] Preferably, the first connecting block is fixed to the port sidewall of the first cable tray by bolts or welding, and the second connecting block is fixed to the port sidewall of the second cable tray by bolts or welding.

[0015] Preferably, the intelligent monitoring module further includes a wireless communication unit, a power supply unit, and an audible and visual alarm module. The microprocessor unit remotely transmits temperature data and alarm information to the monitoring center or mobile cloud platform through the wireless communication unit. The power supply unit is used to supply power to all electrical devices in the intelligent monitoring module. The audible and visual alarm module is used to automatically trigger an alarm when the temperature sensor detects that the temperature exceeds a preset threshold, and at the same time pushes abnormal information through the wireless communication unit.

[0016] Preferably, the insert block has at least two first insertion holes, and the outer wall of the slot block has at least two second insertion holes.

[0017] A fire protection method for quick-installation cable trays with integrated intelligent temperature detection, implemented based on a quick-installation cable tray fire protection device with integrated intelligent temperature detection, includes the following steps:

[0018] Step 1: Align the plug in the male interface assembly fixed to the side wall of the first cable tray port with the slot in the groove block of the female interface assembly fixed to the side wall of the second cable tray port. Push the first cable tray so that the plug is fully inserted into the slot along the guide slope at the outer edge of the slot, so that the first insertion hole on the plug is aligned with the second insertion hole on the outer side wall of the groove block and the axis coincides. At the same time, the sealing strip on the inner side wall of the slot is squeezed and adhered.

[0019] Step 2: Under the elastic force of the torsion spring, the elastic buckle rotates around the central pivot, causing the locking block on the inner side of the elastic buckle to pass through the second insertion hole and the first insertion hole in sequence, locking the insertion block in the slot, thus completing the boltless splicing of the first cable tray and the second cable tray.

[0020] Step 3: The temperature sensor belt collects local temperature data of the cable in real time and transmits the data to the microprocessor unit in the monitoring element box. The microprocessor unit performs logical judgment on the temperature data. When the temperature exceeds the preset threshold, it triggers the audible and visual alarm module to issue a warning. At the same time, the temperature data and alarm information are remotely transmitted to the monitoring center or mobile cloud platform through the wireless communication unit.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention uses a quick-installation splicing module composed of male and female interface components. It utilizes the mechanical interlocking structure of T-shaped plugs and slots in conjunction with elastic buckle locking to achieve boltless quick installation and disassembly between the first cable tray and the second cable tray. This avoids the problems of time-consuming installation, difficulty in high-altitude operations, and loosening and corrosion of bolts that exist in traditional bolted connections, and greatly improves construction efficiency and connection reliability.

[0023] 2. This invention embeds a temperature sensing strip into the inner wall groove of the top port of the cable tray, allowing the detection end to directly contact the cable surface. This enables close-range and accurate monitoring of the temperature of the connection point and the cable inside the cable tray, overcoming the shortcomings of traditional external sensors that can only indirectly measure ambient temperature, cannot capture hot spots, and are easily damaged due to exposed cables. This significantly improves the accuracy of temperature measurement.

[0024] 3. This invention, through an intelligent monitoring system integrating a microprocessor unit, a wireless communication unit, a power supply unit, and an audible and visual alarm module, can automatically trigger graded early warnings and alarms based on preset temperature thresholds, and remotely transmit data to a monitoring center or mobile cloud platform. This allows maintenance personnel to monitor the temperature status of cable tray connection points in real time, respond promptly in the early stages of a fault, effectively prevent electrical fires, and maintain the integrity of the cable tray structure without requiring additional wiring or external power supply.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To address the issues of time-consuming installation, easy loosening and overheating, and lack of real-time and accurate temperature monitoring at connection points in existing cable tray bolt connections, please refer to [link to relevant documentation]. Figure 1-5 This embodiment provides the following technical solution:

[0033] A quick-installation cable tray fire protection device with integrated intelligent temperature detection, including the first cable...

[0034] The cable tray 10 and the second cable tray 20 are connected at the joint by a quick-connect splicing module. There are two sets of quick-connect splicing modules, which are located on both sides of the first cable tray 10 and the second cable tray 20 respectively. Each set of quick-connect splicing modules includes a male interface component 30 and a female interface component 40.

[0035] The male interface component 30 includes a first connecting block 31 and a plug block 32. The first connecting block 31 is fixed to the port side wall of the first cable tray 10 by bolts or welding. The end of the plug block 32 is fixedly connected to the middle position of the first connecting block 31 to form a T-shaped structure. The plug block 32 is horizontally arranged and has at least two first plug holes 33.

[0036] The female interface assembly 40 includes a second connecting block 41 and a slot block 42. The second connecting block 41 is fixed to the port side wall of the second cable tray 20 by bolts or welding. The end of the slot block 42 is fixedly connected to the middle position of the second connecting block 41 to form a T-shaped structure. The slot block 42 is horizontally arranged and horizontally aligned with the plug block 32.

[0037] The slot 42 has a slot 43 on the side facing the insert 32, through which the insert 32 passes. The outer wall of the slot 42 has at least two second insertion holes 44. After the insert 32 is fully inserted into the slot 43, the second insertion holes 44 are aligned with the first insertion holes 33 and their axes coincide. The outer edge of the slot 43 is also provided with a guide slope 410 to guide the insert 32 into the slot 43 smoothly. The inner wall of the slot 43 is provided with a sealing strip 411. When the insert 32 and the slot 43 are joined, the sealing strip 411 is squeezed and adhered to prevent dust and moisture from entering the interface.

[0038] An elastic buckle 45 is also provided on the outside of the groove block 42. The elastic buckle 45 and the second cable tray 20 are provided with rotating support blocks 46 on opposite sides. The rotating support blocks 46 are connected by an intermediate pivot 47. A torsion spring 48 is provided on the outer sleeve of the intermediate pivot 47. The two spring arms of the torsion spring 48 are fixedly connected to the sides of the second cable tray 20 and the elastic buckle 45, respectively. The inner side of the elastic buckle 45 is also provided with a locking block 49. When the elastic buckle 45 covers the outside of the slot block 42, the locking block 49 can be inserted into the second socket 44 and the first socket 33, so that the plug 32 is limited in the slot 43 and cannot be pulled out, thereby realizing the connection between the first cable tray 10 and the second cable tray 20. When it is necessary to pull out the plug 32, press the end of the elastic buckle 45 away from the locking block 49, so that the locking block 49 rotates slightly around the axis of the central pivot 47 until it is pulled out from the second socket 44 and the first socket 33, thereby releasing the limitation of the slot block 42 and the plug 32.

[0039] A monitoring element box 50 is also provided on one side of the first cable tray 10 or the second cable tray 20. The monitoring element box 50 contains an intelligent monitoring module, which includes a temperature sensing strip 51, a microprocessor unit, a wireless communication unit, a power supply unit, and an audible and visual alarm module. The temperature sensing strip 51 is an energy-saving thermistor sensing strip, which is embedded in the inner wall groove 11 of the top port of the first cable tray 10 and the second cable tray 20. Through the detection end of the temperature sensing strip 51, the cable temperature of various parts of the first cable tray 10 and the second cable tray 20 can be directly and accurately measured.

[0040] The microprocessor unit is electrically connected to the temperature sensing strip 51 and is used to receive and process the data from the temperature sensing strip 51 and perform logical judgments. The wireless communication unit is connected to the microprocessor unit and uses LoRa, NB-IoT or ZigBee low-power wide area network communication to remotely transmit temperature data and alarm information to the monitoring center or mobile cloud platform.

[0041] The power supply unit uses a high-performance lithium-ion battery or supercapacitor to power the entire intelligent monitoring module. The audible and visual alarm module 52 is used to automatically trigger an alarm when the temperature sensor 51 detects that the temperature exceeds the preset threshold, emitting a red warning light and a buzzer reminder. At the same time, it pushes abnormal information through the wireless communication unit. For example, when the set temperature T < 60℃, the system is in normal condition; when 60℃ ≤ T < 70℃, a first-level warning is triggered, and the audible and visual alarm module 6 is activated, and the point is marked in yellow on the platform to remind maintenance personnel to pay attention; when 70℃ ≤ T < 85℃, a second-level alarm is triggered, the platform pops up an alarm window, and sends an SMS to the bound mobile phone; when T ≥ 85℃, a third-level emergency alarm is triggered, the platform continuously sends audible and visual alarm data, and immediately notifies relevant personnel for emergency handling.

[0042] The operation of this device mainly includes the following steps:

[0043] Step 1: Align the insert block 32 in the male interface assembly 30 fixed to the side wall of the first cable tray 10 with the slot 43 of the groove block 42 in the female interface assembly 40 fixed to the side wall of the second cable tray 20. Push the first cable tray 10 so that the insert block 32 is fully inserted into the slot 43 along the guide slope 410 at the outer edge of the slot 43, so that the first insertion hole 33 on the insert block 32 is aligned with the second insertion hole 44 on the outer side wall of the groove block 42 and their axes coincide. At the same time, the sealing strip 411 on the inner side wall of the slot 43 is squeezed and adhered.

[0044] Step 2: Under the elastic force of the torsion spring 48, the elastic buckle 45 rotates around the central pivot 47, causing the locking block 49 on the inner side of the elastic buckle 45 to pass through the second insertion hole 44 and the first insertion hole 33 in sequence, locking the insertion block 32 in the slot 43, thus completing the boltless splicing of the first cable tray 10 and the second cable tray 20.

[0045] Step 3: Temperature sensor 51 collects local temperature data of the cable in real time and transmits the data to the microprocessor unit in the monitoring element box 50. The microprocessor unit performs logical judgment on the temperature data. When the temperature exceeds the preset threshold, it triggers the audible and visual alarm module 6 to issue a warning. At the same time, the temperature data and alarm information are remotely transmitted to the monitoring center or mobile cloud platform through the wireless communication unit.

[0046] Working principle: During the rapid assembly of the first cable tray 10 and the second cable tray 20, the male interface assembly 30 fixed to the side wall of the first cable tray 10 port is first aligned with the female interface assembly 40 fixed to the side wall of the second cable tray 20 port. Guided by the guide ramp 410, the insert 32 in the male interface assembly 30 smoothly inserts into the slot 43 of the groove block 42 in the female interface assembly 40. The sealing strip 411 on the inner side wall of the slot 43 is compressed and adhered, providing dust and water protection. After the insert 32 is fully inserted into the slot 43, the first insertion hole 33 on the insert 32 aligns with the second insertion hole 44 on the groove block 42, and their axes coincide. At this time, under the elastic force of the torsion spring 48, the elastic buckle 45 rotates around the central pivot 47, causing the locking block 49 on the inner side of the elastic buckle 45 to pass through the second insertion hole 44 and the first insertion hole 33 in sequence, thereby locking the insertion block 32 and completing the boltless quick-connect connection between the first cable tray 10 and the second cable tray 20. When disassembly is required, press the end of the elastic buckle 45 away from the locking block 49 to release the locking block 49 from the hole and thus release the limit.

[0047] During operation, the intelligent monitoring module inside the monitoring component box 50 begins to work. The temperature sensing strip 51, embedded in the groove 11 on the inner wall of the top port of the first cable tray 10 and the second cable tray 20, directly contacts and collects temperature data from various parts of the cable in real time. The microprocessor unit receives the signal from the temperature sensing strip 51 and performs logical judgments: when the temperature is below 60℃, the system remains normal; when the temperature reaches the range of 60℃ to 70℃, a first-level warning is triggered, the audible and visual alarm module 6 emits a red warning light and a buzzer, and pushes a yellow marker to the platform via the wireless communication unit; when the temperature rises to 70℃ to 85℃, a second-level alarm is triggered, the platform pops up an alarm window and sends a text message to the bound mobile phone; when the temperature reaches 85℃ or above, a third-level emergency alarm is triggered, with continuous audible and visual alarms and notification of relevant personnel for emergency handling. The power supply unit continuously supplies power to the entire monitoring module, ensuring long-term stable operation of the device.
