Description

Technical Field

[0001] This invention relates to the field of control cabinets, and particularly to a laboratory power control cabinet and its method of use. Background Technology

[0002] Laboratory power control cabinets are key equipment for the centralized distribution and management of electrical energy. They control the power switches of various electrical components and circuits. Their performance directly affects the efficiency and success rate of experiments. They are widely used in scientific research, teaching and product development.

[0003] However, in laboratory power control cabinets, power modules are typically fixed inside the cabinet, resulting in complex wiring. When a power module malfunctions or needs upgrading, the entire control cabinet often needs to be powered off, requiring tedious disconnection and rewiring work, leading to large-scale laboratory downtime, long repair cycles, and severely impacting experimental progress. Furthermore, laboratory equipment configurations and power requirements frequently change, making it difficult for traditional fixed control cabinets to achieve rapid and low-cost capacity expansion or adjustment. Additionally, the compact internal space of the control cabinet and the dense concentration of power components mean that traditional cooling solutions typically involve installing a few fans on the cabinet for overall airflow, resulting in chaotic airflow that fails to effectively cool the high-heat power modules. This easily leads to heat accumulation inside the cabinet, causing localized overheating, accelerating the aging of electronic components, and even triggering overheat protection or equipment failure, threatening the continuity and stability of experiments. Furthermore, the installation of the power module is separated from the electrical connection. When replacing the module, the user needs to first complete the mechanical fixing and then perform complex wiring operations for the power and control lines. This process is not only inefficient and requires high professional skills from the operators, but also increases the risk of poor contact, incorrect wiring and accidental electric shock due to frequent wiring, so safety needs to be improved. Summary of the Invention

[0004] The main objective of this invention is to provide a laboratory power control cabinet and its usage method, which can complete the connection of power lines and control lines in one step, achieve plug-and-play, greatly reduce downtime, and has high installation efficiency and low operational risk.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A laboratory power control cabinet and its usage method are disclosed, comprising a control cabinet body, an extension platform, and a control panel. The extension platform is integrally formed at the front end of the control cabinet body. Multiple mounting plate structures are fixedly installed on the inner rear end of the control cabinet body. A modular power supply box is disposed on the inner side of the mounting plate structure. Connecting pins are welded to both sides of the modular power supply box.

Multiple conductive plugs are fixedly installed at the rear end of the modular power supply box. Multiple terminal blocks are fixedly installed inside the modular power supply box. Multiple fan mounting frames are fixedly installed on the inner rear end of the control cabinet body below the mounting plate structure, and fan structures are fixedly installed inside the fan mounting frames.

[0007] As a further embodiment of the present invention, a drawer box is movably installed on the inner side of the extension platform, a storage box is movably installed on the bottom of the control cabinet body, a display screen is fixedly installed on the front end of the control panel, and multiple control buttons are movably installed on the front end of the control panel below the display screen.

[0008] As a further embodiment of the present invention, the mounting plate structure includes a mounting frame, a ventilated base plate, a socket mounting groove, a conductive socket, a docking slide, and a snap-fit ​​seat. The mounting frame is fixedly installed on the inner rear end of the control cabinet body, the ventilated base plate is fixedly installed on the lower end of the mounting frame, the socket mounting groove is opened on the inner wall of the mounting frame, the socket mounting groove is fixedly installed on the front end of the mounting frame, the conductive socket is fixedly installed on the inner side of the socket mounting groove, and the snap-fit ​​seat is fixedly installed on the top inner side of the mounting frame.

[0009] As a further embodiment of the present invention, the socket mounting groove is connected to the interior of the mounting frame, and the conductive socket is connected to the control panel via a wire.

[0010] As a further embodiment of the present invention, the modular power supply box is inserted into the mounting frame, the mating pins are inserted into the socket mounting slots for connection, the lower end of the modular power supply box is attached to the ventilated base plate, the conductive plug is connected to the conductive socket, and the terminal block is connected to the conductive plug via a circuit.

[0011] As a further embodiment of the present invention, a sealing door panel is movably installed at the rear end of the module power supply box, and push-pull handles are fixedly installed on both sides of the sealing door panel at the rear end of the module power supply box. A snap-fit ​​block is fixedly installed at the front of the upper end of the module power supply box, and the snap-fit ​​block is inserted into the snap-fit ​​seat for connection.

[0012] As a further embodiment of the present invention, the fan structure includes a fan box, an air guide block, a ventilated top plate, a fan frame, and fan blades. The fan box is fixedly installed inside the fan mounting frame, the air guide block is fixedly installed inside the fan box, the ventilated top plate is fixedly installed at the upper end of the fan box, the fan frame is fixedly installed at the rear end of the fan box, and the fan blades are rotatably installed inside the fan frame.

[0013] As a further embodiment of the present invention, the fan box and the module power supply box are arranged vertically one-to-one, the ventilated top plate is located below the ventilated bottom plate, and the fan blades blow air into the fan box.

[0014] A method for using a laboratory power control cabinet, the method specifically includes the following steps:

[0015] Step 1: The main body of the control cabinet is the main part of the control cabinet. The extended platform is used for placing items, and the drawers and storage boxes are used for storing items. The display screen and control buttons in front of the control panel are used for control observation and power switch operation.

[0016] Step 2: The modular power supply box is initially separated from the mounting frame. Open the sealed door at the rear of the modular power supply box, install the laboratory power electrical components and wiring on the inner wall of the modular power supply box and connect them to the terminal block. At the same time, the terminal block is electrically connected to the conductive socket.

[0017] Step 3: The module power box is inserted into the mounting frame, and the docking pins are simultaneously inserted into the docking grooves for positioning. The snap-fit ​​bracket is inserted with pins to fix the snap-fit ​​block, thus fixing the module power box. The module power box is positioned and installed in the mounting frame, and the conductive plug and conductive socket are connected to establish the power connection structure of the control cabinet, so that the power control in the module power box can be realized through the control panel.

[0018] Step 4: After the module power supply box is installed, insert the fan box into the fan mounting frame and arrange it perpendicular to the module power supply box. After the fan blades in the fan frame run, they send air into the fan box. The air moves upward along the arc of the air guide block, passes through the ventilated top plate, the ventilated top plate and the bottom mesh plate in sequence and enters the module power supply box. The heat inside the module power supply box is carried out and blown out from the top mesh plate, thus performing one-to-one exhaust and heat dissipation inside the module power supply box.

[0019] The beneficial effects that can be achieved by the above embodiments of the present invention include: the modular power supply box can be quickly connected to the socket mounting slot of the mounting frame through the docking pins and fixed with the snap-fit ​​block and snap-fit ​​seat, realizing the plug-and-play effect, so that the modular power supply box can be installed, replaced and maintained independently, greatly reducing downtime, simplifying the installation process, and facilitating fault diagnosis and component upgrades, which is particularly suitable for the ever-changing needs of the laboratory.

[0020] The main body of the control cabinet adopts an integrated design. When the modular power supply box and the mounting frame are installed, the conductive plug and the conductive socket are connected synchronously. When separated, they are also disassembled synchronously, realizing the synchronous disassembly and assembly of the power supply during modular disassembly and assembly. This eliminates the trouble of setting up control lines. In addition, the conductive socket is reliably connected to the terminal block through the conductive plug, ensuring the stability of power transmission. At the same time, it enhances the sealing and portability of the module, preventing dust intrusion and accidental electric shock. This structure not only saves space, but also meets laboratory safety standards.

[0021] It supports the parallel installation of multiple modular power supply boxes, each of which can be controlled independently to adapt to the power needs of different laboratories. This results in rapid deployment and heat dissipation, allowing the control cabinet to be flexibly expanded according to the scale of the experiment, avoiding the high cost of replacing the entire unit, and facilitating customized expansion.

[0022] The fan blades deliver air into the fan housing. After being guided by the air guide block, the airflow passes through the ventilated top plate and bottom mesh plate into the module power supply box, and finally exits from the top mesh plate, forming a continuous airflow circulation. The one-to-one vertically arranged fan structure achieves targeted heat dissipation. The active heat dissipation method effectively reduces the internal temperature, avoids equipment failure caused by overheating, and extends the service life of the power supply components.
