Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an embedded installation mechanism for a low-voltage power distribution cabinet. Background Art

[0002] A low-voltage distribution cabinet refers to one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment. The manufacturer is responsible for completing all internal electrical and mechanical connections. It is a combination of structural components that are completely assembled together and used for power conversion and control of lighting and power distribution. When installing a low-voltage distribution cabinet, the low-voltage distribution cabinet can be embedded in the wall for installation according to installation requirements. When embedded, in order to ensure the stable installation of the low-voltage distribution cabinet, it is usually necessary to use a mounting structure to achieve the installation of the low-voltage distribution cabinet, thereby facilitating the stable use of the low-voltage distribution cabinet.

[0003] Since low-voltage distribution cabinets are installed in the wall, heat is easily accumulated inside the cabinet when used for a long time. The lack of efficient heat dissipation measures is not conducive to the long-term use of the equipment and can easily cause component burns or even fires. Utility Model Content

[0004] The utility model aims to provide an embedded installation mechanism for a low-voltage power distribution cabinet.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] It includes a wall, which is provided with a storage groove, in which a distribution cabinet body is embedded and placed, and electronic devices are fixedly installed on the inner wall of the distribution cabinet body. A plurality of support plates are fixedly provided on the bottom of the distribution cabinet body. A pair of porous fan boxes are extended from the bottom wall and the top wall inside the distribution cabinet body, and a ventilation fan is installed on the inner wall of the porous fan box. The outer bottom wall and the top wall of the distribution cabinet body are provided with air duct openings connected to the porous fan boxes, and an air circulation belt is arranged between the storage groove and the distribution cabinet body.

[0007] By adopting the above technical scheme, the ventilation fans are also arranged in pairs, which can cooperate with each other to circulate the air inside the distribution cabinet body, inhale cold air and discharge hot air at the same time, circulate and cool the internal electronic devices, and ensure that they are in a good low-temperature working environment. Since the hot air density is lower and is located at the top of the distribution cabinet body, and the cold air density is higher and is located at the bottom of the distribution cabinet body, the ventilation fan at the bottom of the distribution cabinet body adopts an intake rotation direction, and the ventilation fan at the top of the distribution cabinet body adopts an exhaust rotation direction, forming a bottom-up air duct circulation route to avoid heat accumulation inside the distribution cabinet body and excessive temperature causing damage to electronic devices. The setting of the air circulation belt can greatly enhance the heat exchange rate between the distribution cabinet body and the outside world while being embedded in the installation.

[0008] Furthermore, a rolling pulley is rotatably mounted on the bottom wall of the support plate, and a pulley groove matching the rolling pulley is formed on the bottom wall of the storage groove.

[0009] By adopting the above technical solution, during the installation and replacement of the distribution cabinet body, the rolling pulley converts the sliding friction between the distribution cabinet and the storage slot into rolling friction, which greatly reduces the friction and makes installation and replacement more convenient. After the distribution cabinet body reaches the specified position, the rolling pulley will fall into the matching pulley groove and engage, so that the distribution cabinet body can be positioned and placed more stably.

[0010] Furthermore, the side walls and the top wall of the storage slot are provided with fixing slots, the fixing slots are embedded with fixing partitions, a rubber strip is fixedly provided on a side of the fixing partition away from the fixing slot, and the rubber strip is provided against the outer wall of the power distribution cabinet body.

[0011] By adopting the above technical solution, the fixed partition with the rubber strip is embedded in the fixed groove and fixed. At this time, the fixed partition cooperates with the rubber strip to firmly limit the distribution cabinet body from the top wall and the two side walls, and then combined with the limiting of the rolling pulley on the bottom wall and the pulley groove, the distribution cabinet body is firmly installed in the storage groove. The setting of the rubber strip can not only firmly engage the distribution cabinet body, but also avoid damage caused by rigid collision between the fixed plate and the distribution cabinet body.

[0012] Furthermore, the fixed partition divides the air circulation belt into a windless belt, an air inlet belt and an air outlet belt. The air circulation belt is covered with a protective pressure plate, and the protective pressure plate is penetrated by air holes matching the air inlet belt and the air outlet belt. The protective pressure plate is penetrated by a number of bolts connecting to the wall.

[0013] By adopting the above technical solution, the windless belt is located on the side of the air circulation belt, the air inlet belt is located at the bottom of the air circulation belt, and the air outlet belt is located at the top of the air circulation belt. The setting of the vents facilitates the circulation of airflow to form a complete air duct. The setting of the protective pressure plate covers the air circulation belt to prevent the outer wall of the distribution cabinet body from being damaged, thereby improving the overall protection capability.

[0014] Furthermore, the power distribution cabinet body is hingedly provided with a cover plate covering the inner wall, the cover plate is provided with a transparent observation window, and the outer wall of the cover plate is fixedly provided with a door handle.

[0015] By adopting the above technical solution, the setting of the observation window allows the operator to observe the operation status inside the distribution cabinet body, and the door handle facilitates the opening and closing of the cover.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] 1. The porous fan box, ventilation fan, air duct opening and air circulation belt are used to form a bottom-up heat dissipation air duct circulation route to reduce the working temperature of internal electronic components;

[0018] 2. The rolling pulley and pulley groove are used to greatly reduce the friction, making installation and replacement more convenient and more stable;

[0019] 3. Fixed grooves, fixed partitions and rubber strips are used to firmly fit the distribution cabinet body while avoiding damage caused by rigid collision between the fixed plate and the distribution cabinet body. BRIEF DESCRIPTION OF THE DRAWINGS
