Description

Technical Field

[0001] The utility model relates to a protective device inside an electrical cabinet. Background Art

[0002] To ensure operational safety and comply with press safety production standards, electrical cabinets typically incorporate protective devices on components susceptible to electric shock to prevent accidental contact by maintenance or operators, potentially leading to accidents. However, there are many limitations when selecting and installing protective covers: A large protective device takes up limited cabinet space; a small protective device provides no protection; installing an original electrical cover can lead to long procurement cycles and costs; and if protection isn't factored into the initial design, retrofitting it later can make on-site installation a hassle. Utility Model Content

[0003] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a protective device inside an electrical cabinet.

[0004] A protective device in an electrical cabinet comprises a cabinet body and a protective plate. The protective plate is fixed to a frame at an opening of the cabinet body via a plurality of fixing brackets, and the protective plate is made of a transparent material.

[0005] Furthermore, the fixing bracket is an L-shaped plate structure, which includes a first plate and a second plate. The first plate and the second plate are perpendicular to each other. The first plate is fixedly connected to the frame by at least two bolts, and the second plate is fixedly connected to the protective plate by bolts.

[0006] Furthermore, the protective plate is an acrylic plate.

[0007] Furthermore, the first flat plate is connected to the frame via two bolts, and the second flat plate is connected to the protective plate via one bolt.

[0008] Furthermore, the cabinet is made of stainless steel or aluminum alloy.

[0009] Furthermore, a shock-absorbing cushion or a spring shock absorber is added to the connection between the fixing bracket and the cabinet frame and the protective plate.

[0010] Furthermore, an intelligent sensing device is added to the edge of the protective plate. The intelligent sensing device is an infrared sensor or a microwave sensor, which is used to monitor the status of the protective plate in real time.

[0011] Furthermore, the bolts are coated with a locking agent.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0013] Easy and quick installation: There is no need to remove the installed components in the cabinet or change the original structure of the cabinet. The protective device only needs to be fixed directly on the cabinet frame, which greatly saves installation time and labor costs.

[0014] Comprehensive protection: Using a whole piece of acrylic board as the protective material can solve the protection problem of the entire electrical cabinet at one time, effectively isolating personnel from direct contact with internal components of the electrical cabinet, and avoiding safety hazards such as electric shock.

[0015] Transparent and visible: Acrylic panels have good transparency, so when the electrical cabinet door is open, personnel can intuitively observe the working conditions of each component, which is convenient for daily maintenance and troubleshooting.

[0016] Flexible adaptation: The number of fixing brackets can be adjusted according to the actual size of the electrical cabinet to ensure that the acrylic sheet is firmly fixed and adapt to the needs of electrical cabinets of different sizes and shapes. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, cabinet 1, frame 2, fixing bracket 3, bolt 4;

[0022] A protective device inside an electrical cabinet includes a cabinet body 1 and a protective plate. The protective plate is fixed to a frame 2 at an opening of the cabinet body 1 through multiple fixing brackets 3. The protective plate is made of a transparent material, and is an acrylic plate.

[0023] In this embodiment, the fixing bracket 3 is an L-shaped plate structure, which includes a first plate and a second plate. The first plate and the second plate are perpendicular to each other. The first plate is fixedly connected to the frame 2 by at least two bolts 4, and the second plate is fixedly connected to the protective plate by bolts 4.

[0024] In this embodiment, the first plate is connected to the frame via two bolts, and the second plate is connected to the protective plate via one bolt.

[0025] In this embodiment, the cabinet is made of stainless steel or aluminum alloy.

[0026] In this embodiment, a shock-absorbing cushion or a spring shock absorber is added to the connection between the fixing bracket, the cabinet frame and the protective plate.

[0027] In this embodiment, an intelligent sensing device is added to the edge of the protective plate. The intelligent sensing device is an infrared sensor or a microwave sensor, which is used to monitor the status of the protective plate in real time.

[0028] In this embodiment, the bolts are coated with a locking agent.

[0029] Instructions for use: First, when making the acrylic sheet, you need to measure the size of the cabinet frame, calculate the external dimensions of the acrylic sheet, and cut it after the measurement is completed; install the fixing bracket on the cabinet frame. The specific number is based on the actual size of the cabinet, and it is necessary to ensure that the acrylic sheet is firmly fixed; place the acrylic sheet on the cabinet for trial installation, determine the position of the fixing holes of the acrylic sheet according to the installation position of the fixing bracket, and process it; install the processed acrylic sheet on the fixing bracket; in this way, a protective device that can not only observe the operation of cabinet components but also protect personnel safety is installed.
