Description

Technical Field

[0001] This invention relates to the technical field of power distribution cabinets, and more specifically, to a power distribution cabinet that integrates multi-dimensional status sensing and electrical control interlocking functions for strong and weak current isolation. Background Technology

[0002] In recent years, with the strict requirements of the state on safety production standards for major engineering projects, and the in-depth promotion of digital and refined management of transportation infrastructure construction and construction sites, temporary power supply systems are facing unprecedented challenges in safety management and power supply reliability.

[0003] The traditional temporary power distribution cabinets that are widely used at present have revealed multiple structural and functional defects in actual use, mainly in terms of physical security and access control. The core problem lies in the extreme imperfection of their mechanical structure.

[0004] Traditional distribution cabinets typically rely on simple mechanical locks and lack multiple authentication or reliable electrical control interlocking and electrical locking devices. This allows unauthorized personnel, even non-professionals, to easily bypass their authority to open the cabinet doors and perform unauthorized operations. As a result, unauthorized wiring, overload operation, and other phenomena are extremely common, posing serious safety hazards such as short circuits, overloads, and even fires.

[0005] Meanwhile, the power distribution cabinet cannot perceive the critical status inside the cabinet in real time. This information blind spot not only makes the cabinet vulnerable to malicious damage or frequent incidents of damage to critical equipment, but also prevents the back-end operation and maintenance platform from timely and effectively detecting anomalies and responding, thus delaying troubleshooting and repair time.

[0006] Furthermore, as temporary power systems undergo digital transformation, sensitive low-voltage electrical equipment such as smart gateways and communication modules must be integrated. Traditional distribution cabinets fail to adequately address electromagnetic radiation, transient voltage fluctuations, or high-order harmonic pollution generated by high-voltage circuits. These interferences directly couple to or radiate into the low-voltage system, severely impacting the accuracy of data acquisition and the reliability and stability of remote communication. Summary of the Invention

[0007] The purpose of this invention is to provide a strong and weak current isolation distribution cabinet that integrates multi-dimensional state perception and electrical control interlocking functions, in order to solve the problem of low safety in existing distribution cabinets.

[0008] The present invention is implemented as follows: a strong and weak current isolation distribution cabinet integrating multi-dimensional state perception and electrical control interlocking functions includes a cabinet body and a multi-dimensional state perception system. The cabinet body has an internal cavity and a side opening on the cabinet body, which is covered by a cabinet door. The cabinet door is equipped with an electronically interlocked door lock, which includes a swing-type latch. When the latch is connected to the cabinet body, the cabinet door is in a closed state, and the side opening is closed. When the latch is disengaged from the cabinet body, the cabinet door is in an open state, and the side opening is open. The inner cavity is provided with an isolation plate, which divides the inner cavity into a high-voltage area and a low-voltage area, and the high-voltage area and the low-voltage area are arranged independently of each other; the outer periphery of the isolation plate is provided with a conductive strip made of conductive material, which abuts against the inner sidewall of the inner cavity to isolate the high-voltage area and the low-voltage area from each other.

[0013] Furthermore, the terminal block has a connecting wire that passes through the protective sleeve and is clamped and fixed by the protective sleeve.

[0014] Furthermore, the door lock includes an electromagnetic actuator, a worm gear, and a worm. The latch is connected to the worm gear, and the worm is connected to the electromagnetic actuator. The electromagnetic actuator drives the worm to rotate, and the worm synchronously drives the worm gear to rotate, which in turn causes the latch to swing.

[0015] Furthermore, the top of the inner cavity is provided with a mounting base, and the mounting base is provided with a mounting groove with a bottom opening. The smoke temperature sensor is disposed in the mounting groove and is arranged facing downwards through the bottom opening. The mounting base is provided with a flow guide shroud, which is arranged in a ring to form a flow guide channel. The upper end of the flow guide shroud has a flow outlet, and the lower end of the flow guide shroud has a flow inlet. The upper end of the flow guide shroud surrounds the outer periphery of the mounting base, and the flow inlet is aligned and connected to the mounting groove. Along the flow guide shroud from top to bottom, the diameter of the flow guide channel gradually increases. The mounting base is provided with multiple air outlets, which are arranged around the circumference of the mounting base at intervals. The inner end of each air outlet is connected to the mounting groove, and the outer end of each air outlet penetrates the outer circumference of the mounting base.

[0016] Furthermore, the flow inlet is covered with an elastic membrane, which has multiple through holes arranged vertically, and the flow channel communicates with the inner cavity through the through holes; the elastic membrane is provided with multiple elastic cylinders, and the elastic cylinders have channels arranged vertically.

[0023] Reference Figure 1-5 The image shows a preferred embodiment of the present invention.

[0024] A strong and weak current isolation distribution cabinet integrating multi-dimensional state perception and electrical control interlocking functions includes a cabinet 100 and a multi-dimensional state perception system. The cabinet 100 has an internal cavity and a side opening on the cabinet 100, which is covered by a cabinet door. The cabinet door is equipped with an electronically interlocked door lock 200, which includes a swing-type latch 201. When the latch 201 is connected to the cabinet body 100, the cabinet door is in a closed state, and the side opening is closed. When the latch 201 is disengaged from the cabinet body 100, the cabinet door is in an open state, and the side opening is open. An isolation plate 300 is provided in the inner cavity, which divides the inner cavity into a high-voltage area 103 and a low-voltage area 102. The high-voltage area 103 and the low-voltage area 102 are arranged independently of each other. A conductive strip made of conductive material is provided on the outer periphery of the isolation plate 300. The conductive strip abuts against the inner side wall of the inner cavity to isolate the high-voltage area 103 and the low-voltage area 102 from each other. The multi-dimensional state perception system includes a latch position sensor for detecting the position of the latch 201, a cabinet door state sensor for monitoring the cabinet door state, and a controller. The controller is located in the low-voltage area 102. The latch position sensor and the cabinet door state sensor are electrically connected to the controller. The controller acquires the monitoring data from the latch position sensor and the cabinet door state sensor and compares it with a preset threshold.

[0025] The aforementioned integrated multi-dimensional status perception and electrical control interlocking function of the strong and weak current isolation distribution cabinet is equipped with an electrically controlled interlocking door lock 200 on the cabinet door, which overcomes the shortcomings of traditional distribution cabinets that lack reliable locking devices, effectively ensuring the safe and reliable locking of the cabinet door, and realizing remote control and status monitoring. Secondly, by arranging the isolation plate 300, the inner cavity is divided into a high-voltage area 103 and a low-voltage area 102. The conductive strip is attached to the inner wall of the inner cavity, which can achieve high-efficiency electromagnetic shielding and physical isolation between strong and weak currents, ensuring the operational reliability of the communication system in the low-voltage area 102 and meeting the requirements of the IP54 protection level of the distribution box. In addition, by arranging latch position sensors and cabinet door status sensors, the physical status of the cabinet 100 can be monitored in real time and abnormal status can be identified, ensuring safety and reliability during operation.

[0026] The edge of the isolation plate 300 is embedded with a conductive strip made of conductive rubber. The isolation plate 300 is fixed by a combination of quick buckles and bolts, so that it is in close contact with the inner metal surface of the cabinet 100 and conducts electricity, forming a continuous low impedance grounding loop, thereby constituting the Faraday cage effect and achieving efficient electromagnetic sealing and high-level IP54 protection.

[0027] In this embodiment, the multi-dimensional state perception system includes a smoke and temperature sensor 600. The high-voltage area 103 and the low-voltage area 102 are respectively equipped with smoke and temperature sensors 600, and the smoke and temperature sensors 600 are electrically connected to the controller.

[0028] Cabinet door status sensors can be installed on the edge of the cabinet door to ensure that a signal is triggered only when the cabinet door is tightly closed. Incorporating smoke and temperature sensors can improve the response speed and sensitivity to overheating or fire emanating from the interior cavity.

[0029] In this embodiment, the camera 101 is mounted on the outside of the cabinet 100 via a shockproof base and a multi-angle adjustable universal joint.

[0030] In this embodiment, the low-voltage area 102 is provided with a grounding busbar. The latch position sensor, cabinet door status sensor and smoke and temperature sensor 600 are respectively connected to the grounding busbar through built-in wires. The built-in wires are built into the wiring channel, and the wiring channel is wrapped with an insulating sheath.

[0031] To ensure complete isolation between strong and weak current circuits and the reliability of weak current communication, the isolation plate 300 must divide its internal cavity into a strong current zone 103 and a weak current zone 102. Simultaneously, independent wiring channels must be reserved to ensure that sensor signal lines do not share cable trays with strong current cables, preventing coupling interference. Furthermore, both strong and weak current systems should have independent grounding systems.

[0032] In this embodiment, the high-voltage area 103 is provided with a terminal block, and a protective sleeve 400 is provided on the outside of the terminal block. The protective sleeve 400 is made of insulating material and encloses the terminal block.

[0033] The height of the protective cover should be able to completely cover the high-voltage circuit breaker and terminals, and be close to the circuit breaker and terminals to fundamentally eliminate the hidden dangers of unauthorized wiring. The material of the protective cover should be an insulating material and a high-strength engineering plastic with fire-retardant properties to provide reliable physical protection and electrical safety insulation.

[0034] In this embodiment, the protective sleeve 400 includes two opposing shells 402, which are connected as one unit by a one-way screw 401; the two shells 402 surround each other to form a closed cavity, and the wiring terminals are enclosed in the cavity.

[0035] By using a protective cover and a one-way screw 401 locking mechanism, the phenomenon of unauthorized wiring and connections is physically prevented. At the same time, the built-in multi-dimensional status sensing system can monitor the physical status of the cabinet 100 in real time and identify abnormal statuses, ensuring safety and reliability during operation.

[0036] In this embodiment, the terminal block has a connecting wire that passes through the protective sleeve 400 and is clamped and fixed by the protective sleeve 400, thus preventing the connecting wire from being pulled off.

[0037] In this embodiment, the door lock 200 includes an electromagnetic actuator 202, a worm gear 203, and a worm 204. The latch 201 is connected to the worm gear 203, and the worm 204 is connected to the electromagnetic actuator 202. The electromagnetic actuator 202 drives the worm 204 to rotate, and the worm 204 synchronously drives the worm gear 203 to rotate. The worm gear 203 drives the latch 201 to swing.

[0038] The electronically interlocked door lock 200 enables reliable locking and remote control of the cabinet door. The door lock 200 integrates a redundant electromagnetic actuator 202, which is connected to the latch 201 via a worm gear 203 and worm 204 with self-locking characteristics, ensuring reliable mechanical locking. Simultaneously, the door lock 200 is equipped with a latch position sensor to ensure real-time monitoring of the latch 201's movement. This status information is then fed back to the cloud platform via a low-voltage gateway, enabling remote control of the door lock 200 and ensuring the safety monitoring of the power distribution cabinet.

[0039] In this embodiment, a mounting base 500 is provided at the top of the inner cavity, and a mounting groove 501 with a bottom opening is provided on the mounting base 500. The smoke temperature sensor 600 is disposed in the mounting groove 501 and is arranged facing downward through the bottom opening. The mounting base 500 is provided with a flow guide 700, which is arranged in a ring to form a flow guide channel 701. The upper end of the flow guide 700 has a flow outlet, and the lower end of the flow guide 700 has a flow inlet. The upper end of the flow guide 700 surrounds the outer periphery of the mounting base 500, and the flow inlet is aligned and connected with the mounting groove 501. Along the flow guide 700 from top to bottom, the diameter of the flow guide channel 701 gradually increases. The mounting base 500 is provided with multiple air outlets 502, which are arranged around the circumference of the mounting base 500 at intervals. The inner end of the air outlet 502 is connected to the mounting groove 501, and the outer end of the air outlet 502 passes through the outer periphery of the mounting base 500.

[0040] The mounting slot 501 is arranged facing downwards and the mounting base 500 is installed at the top of the inner cavity, which facilitates the upward flow of air in the inner cavity, so that the smoke temperature sensor 600 can respond efficiently and greatly improve the response sensitivity.

[0041] The air deflector 700 encloses and forms the air deflector channel 701. The air deflector inlet is arranged to face downwards and openly, so that the airflow can enter through the air deflector inlet, flow upwards, and be discharged outwards through the air outlet 502, forming a smooth air deflector path. When the temperature in the inner cavity is too high or when there is a fire and smoke, the airflow will flow upwards under the action of high temperature, and enter the air deflector channel 701 through the air deflector inlet, and then flow out through multiple air outlets 502, so that the smoke and temperature sensor 600 can respond quickly.

[0042] Secondly, the guide channel 701 extends vertically, while the air outlet 502 is formed in the mounting base 500 and is arranged horizontally along the mounting base 500. This facilitates the airflow to enter the guide channel 701 from bottom to top and then flow outward through the air outlet 502, thus forming an efficient airflow path.

[0043] In this embodiment, the flow inlet is covered with an elastic membrane 703, and the elastic membrane 703 is provided with a plurality of membrane through holes 706 arranged vertically through the membrane. The flow channel 701 communicates with the inner cavity through the membrane through holes 706. The elastic membrane 703 is provided with a plurality of elastic cylinders 704, and the elastic cylinders 704 are provided with channels 705 arranged vertically through the cylinder. The elastic cylinder 704 is arranged in the inner cavity. The lower end of the elastic cylinder 704 is connected to the elastic membrane 703 and aligned with and connected to the membrane through hole 706. The upper end of the elastic cylinder 704 extends upward and is arranged in a suspended state in the guide channel 701. Along the direction from bottom to top, the diameter of the elastic cylinder 704 gradually decreases.

[0044] By sealing the flow inlet with an elastic membrane 703, and providing multiple elastic cylinders 704 on the elastic membrane 703, with the elastic cylinders 704 formed in the flow channel 701, the airflow passes through the membrane through hole 706, enters the flow channel 701 through the cylinder channel 705 of the elastic cylinder 704, flows upward in the flow channel 701, and then flows out through the air outlet 502 of the mounting base 500, forming an efficient and smooth airflow.

[0045] Furthermore, by arranging the elastic cylinder 704, the airflow in the air guide channel is prevented from flowing out of the guide inlet in the opposite direction, ensuring that the airflow flows upward in a unidirectional manner in the guide channel. In this way, the smoke temperature sensor 600 can monitor efficiently and quickly.

[0046] In this embodiment, a plurality of inclined cylinders 702 are provided in the middle of the flow guide 700, and the inclined cylinders 702 are arranged in the flow guide channel 701; the lower end of the inclined cylinder 702 is connected to the inner side wall of the flow guide 700 and penetrates the flow guide 700, forming a central hole in the middle of the flow guide 700. The upper end of the inclined cylinder 702 is inclined upward so that the inclined cylinder 702 is inclined in the guide channel 701. The upper end of the inclined cylinder 702 extends toward the mounting groove 501. The upper end of the elastic cylinder 704 is higher than the upper end of the inclined cylinder 702.

[0047] By forming multiple inclined cylinders 702 in the guide channel 701, with the inclined cylinders 702 formed in the middle of the guide hood 700, the guide hood 700 can guide the airflow in the middle. The airflow can not only enter the guide channel 701 through the guide inlet, but also enter the guide channel 701 from the middle of the guide hood 700 through the multiple inclined cylinders 702. Thus, the guide hood 700 can guide the airflow in multiple directions and positions, which greatly improves the efficiency and sensitivity of the smoke temperature sensor 600 in detecting the airflow.

[0048] In addition, the upper end of the elastic cylinder 704 is higher than the upper end of the inclined cylinder 702, so as to prevent the airflow entering the guide channel 701 from the elastic cylinder 704 from flowing back out through the inclined cylinder 702.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
