Description

Technical Field

[0001] The utility model relates to the field of electrical technology, and more particularly to a high and low voltage complete switchgear. Background Art

[0002] In existing technologies, high and low voltage switchgear is an integrated device used for power distribution, control and protection in power systems. It consists of two parts, high voltage and low voltage, and can receive high voltage power from substations and convert and distribute it into low voltage power for use in various industrial, commercial and civil facilities.

[0003] In the existing technology, the mobility of high and low voltage switchgear is significantly insufficient. Due to the large size and weight of the equipment, its design does not fully consider the convenience of movement. As a result, in actual application, the handling and transfer of the equipment becomes quite difficult. Especially when on-site installation or maintenance is required, the movement of the equipment is not only time-consuming and labor-intensive, but also increases the labor intensity and safety risks for operators.

[0004] This difficulty in movement is particularly prominent on rough roads. Since high and low voltage switchgear generally lacks effective moving mechanisms, such as wheels or suspension systems, the equipment is easily affected by bumps and vibrations when moving on uneven ground. This may not only damage the internal structure and electronic components of the equipment, but also pose a threat to the safety of operators. In addition, the cabinet design in the existing technology is often unable to achieve tilting, which limits the operation and installation of the equipment at specific angles and reduces its applicability and flexibility.

[0005] On the other hand, the heat dissipation effect in the existing technology is also an issue that cannot be ignored. High and low voltage complete switchgear will generate a certain amount of heat during operation, and the heat dissipation design of existing equipment is often not perfect, which leads to an increase in the internal temperature of the equipment, affecting its normal operation and life. Poor heat dissipation effect will not only reduce the efficiency of the equipment, but may also cause premature aging or failure of electronic components, thereby increasing maintenance costs and downtime. This heat dissipation problem is particularly obvious in situations of continuous operation or high ambient temperature, posing a challenge to the stability and reliability of the equipment.

[0010] The utility model is further configured such that the adjustment mechanism includes a connecting frame, a mounting plate, a convex block, a bracket and a cylinder, the connecting frame is rotatably mounted on the base frame, and the mounting plate is rotatably mounted on the connecting frame. Such a design allows the mounting plate to tilt as the connecting frame rotates, thereby changing the posture of the cabinet.

[0011] The utility model further comprises a plurality of convex blocks mounted on a mounting plate, the bracket mounted on a base frame, and the ends of the cylinder connected to the connecting frame and the bracket, respectively. The multiple convex blocks increase the contact points with the ground and improve stability. The bracket is fixed to the base frame to provide support for the cylinder. The telescopic movement of the cylinder pushes the connecting frame and the mounting plate to achieve tilting of the cabinet.

[0012] The present invention is further configured such that a cabinet door is rotatably provided on the cabinet body, and an observation window is provided on the cabinet door. The rotating design of the cabinet door makes operation more convenient, and the observation window allows the operator to observe the equipment status without opening the cabinet door, thereby increasing the safety of operation.

[0013] The utility model is further configured as follows: a main synchronous wheel is provided on the main transmission rod, and multiple groups of slave synchronous wheels are provided on the multiple groups of slave synchronous wheels. A transmission chain is connected between the main synchronous wheel and the multiple groups of slave synchronous wheels. The synchronous rotation of the main transmission rod and the slave transmission rod ensures the stability of the cabinet during the movement. The connection of the transmission chain reduces energy loss and improves the efficiency of the moving mechanism.

[0014] The utility model is further configured such that the plurality of groups of convex blocks are rotatably mounted on the mounting plate, and the plurality of groups of convex blocks increase the supporting points of the cabinet when it is tilted, thereby improving stability.

[0015] The present invention is further configured as follows: the cabinet is provided with a heat dissipation mechanism, the heat dissipation mechanism includes a top plate, a mounting seat, a mounting cover, a heat dissipation fan and ventilation holes; the top plate is arranged on the top end of the cabinet, the mounting seat is mounted on the top plate, the mounting cover is mounted on the top end of the mounting seat, the heat dissipation fan is mounted in the mounting cover, and the ventilation holes are provided in multiple groups distributed on both sides of the cabinet; the design of the heat dissipation fan and the ventilation holes effectively reduces the temperature inside the cabinet and improves the heat dissipation efficiency.

[0016] The utility model is further configured such that an isolation net is provided on the inner side of the mounting seat, and the isolation net prevents the entry of external impurities, protects internal components, and prolongs the service life of the equipment.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a high and low voltage complete switchgear with the following beneficial effects:

[0019] 1. The beneficial effects of the moving mechanism are reflected in the ingenuity and practicality of its design. The motor drives the engagement of the main gear and the slave gear, realizing the coordinated rotation of the main transmission rod and the slave transmission rod, thereby driving the rotation of the rotating wheel, so that the cabinet can be easily moved on a plane. This design not only reduces the burden of manual handling, but also improves the efficiency and safety of equipment movement. On rugged roads, the cylinder can be extended and retracted to push the connecting frame and the mounting plate into contact with the ground, thereby realizing the tilting and stable movement of the cabinet, avoiding the movement difficulties and damage to the equipment caused by uneven roads.

[0020] 2. The beneficial effect of the adjustment mechanism is that it can adjust the position and posture of the cabinet as needed. Through the push of the cylinder, the connecting frame can rotate along the base frame, thereby driving the mounting plate to contact the ground. In this way, one end of the cabinet can be lifted up when necessary to achieve tilted placement, which is convenient for operation or installation in specific environments. This adjustment mechanism increases the applicability and flexibility of the equipment, allowing the equipment to adapt to different usage scenarios and needs.

[0021] 3. The beneficial effect of the heat dissipation mechanism is that it can effectively manage and discharge the heat generated by the equipment during operation. The setting of the heat dissipation fan can extract and discharge the hot air in the cabinet while realizing air circulation through the ventilation holes, thereby maintaining the temperature stability in the cabinet and preventing the equipment from overheating. The installation of the isolation net effectively blocks the entry of external impurities, protects the internal components of the equipment, and extends the service life of the equipment. This heat dissipation design not only improves the operating efficiency of the equipment, but also enhances the reliability and stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
