Description

Technical Field

[0001] The utility model relates to the technical field of distribution equipment, in particular to a new type of distribution cabinet for transformers in wind farms. Background Technique

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. Using wind power generation is very environmentally friendly, and the wind energy reserve is huge, so it has been increasingly valued by countries around the world; in wind power plants, distribution cabinets supporting wind turbines are often used to install devices such as transformers;

[0003] In the prior art, the distribution cabinets for transformers in wind farms lack effective installation and fixation. In wind farms with strong winds, they are easily blown down by strong winds; in addition, since sand and dust are often accompanied by the wind, they are easily adhered to the control screens of the distribution cabinets, resulting in inconvenience for staff to observe and use. Therefore, we propose a new type of distribution cabinet for transformers in wind farms. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new type of distribution cabinet for transformers in wind farms, which has a reliable installation and fixation unit and can tightly fix the main cabinet body to the wind turbine column, effectively ensuring the stability of the distribution cabinet in the wind farm environment: the movable double rod and the movable single rod can be pulled outwards, and together with the fitting frame, they form an encircling structure for the wind turbine column; by knocking the hammering block on the side, the ground plug rod can be effectively inserted into the ground, thereby further enhancing the installation stability of the distribution cabinet; and it has a reliable screen dust-proof unit. Through the covering glass, it can prevent dust from falling on the touch screen and affecting the use, and it is convenient to open for using the touch screen, which can effectively solve the problems in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: a new type of distribution cabinet for transformers in wind farms, including a main cabinet body, an installation and fixation unit, and a screen dust-proof unit;

[0006] Main cabinet body: The front end is movably connected with a movable door through a hinge;

[0007] Installation and fixing unit: It includes a fitting rack, movable double rods, vertical connecting rods, movable single rods, vertical insertion rods and hand-pulling blocks. A square fitting rack is fixedly connected to the back of the main cabinet body. The side of the fitting rack facing backward is an inward concave arc structure. The movable double rods and movable single rods are slidably connected inside the fitting rack. The movable double rods and movable single rods are both arc structures of one-third of a circle. The movable double rods are slidably connected to the upper and lower sides inside the fitting rack, and the movable single rod is movably connected to the middle layer inside the fitting rack. A vertical connecting rod is fixedly connected between the movable double rods. Vertical insertion holes are opened at the ends of the movable double rods and movable single rods. The vertical insertion rod passes through the end insertion holes of the movable double rods and movable single rods, and nuts are threadedly connected to both ends of the vertical insertion rod. A hand-pulling block is fixedly connected to the outer side of the end of the movable single rod;

[0008] Screen dust-proof unit: Installed on the front side of the movable door.

[0009] The fitting rack is used to lean against the wind turbine column. The inward concave arc structure can make the fitting rack fit tightly with the wind turbine column. By pulling out the movable double rods and movable single rods outward, the movable double rods and movable single rods of one-third of a circle and the fitting rack together form a surrounding structure for the wind turbine column, and the vertical insertion rod can be used to limit and fix the movable double rods and movable single rods, thereby tightly fixing the main cabinet body to the wind turbine column, effectively ensuring the stability of the power distribution cabinet in the wind farm environment. The hand-pulling block and the vertical connecting rod can both be used for pulling the rod rack, and the vertical connecting rod can play a role in linking the upper and lower parts of the rod body; the screen dust-proof unit can prevent dust from falling on the touch screen and affecting the use, and is convenient to open for using the touch screen.

[0010] Further, the installation and fixing unit further includes ground insertion rods, hammering blocks and through slots I. A ground insertion rod is slidably connected to each of the left and right sides at the lower end of the main cabinet body. A through slot I corresponding to the ground insertion rod horizontally is opened on the side of the main cabinet body. The hammering block is slidably connected inside the through slot I. One end of the hammering block faces inward and is fixedly connected to the upper end of the ground insertion rod, and the other end of the hammering block extends outward. The ground insertion rod is used to insert into the ground, thereby further enhancing the installation stability of the power distribution cabinet. By hammering the hammering block on the side, the ground insertion rod can be effectively inserted into the ground.

[0011] Furthermore, the screen dustproof unit includes a touch screen, a cover glass, a through slot 2 and a connecting short shaft. The touch screen is embedded and installed in the middle of the front end of the movable door. The cover glass is arranged in front of the touch screen and is vertically slidably connected to the movable door. A vertical through slot 2 is provided on the left side of the front end of the movable door. The left side of the cover glass extends into the interior of the through slot 2. A connecting short shaft is fixedly connected at the lower left corner of the cover glass, and the connecting short shaft is slidably connected to the interior of the through slot 2. The touch screen is used to display the operating status of each device inside the power distribution cabinet and information such as current and voltage. The cover glass prevents dust from falling on the touch screen and does not affect the operator's direct observation of the parameter information on the screen from the outside. When it is necessary to set parameters on the touch screen, the cover glass can be slid upward by toggling the connecting short shaft upward, thereby exposing the touch screen for use.

[0012] Furthermore, the screen dustproof unit further comprises an active clamping handle and a clamping block, the front end of the connecting short shaft is rotatably connected with the active clamping handle, and a clamping block is fixedly connected to both the left and right sides of the second upper section of the through slot. The active clamping handle is used to clamp the connecting short shaft by hand and drive the connecting short shaft to slide upwards. During the sliding process, the active clamping handle is in a vertical state, and after moving to the uppermost side, the active clamping handle can be clamped at the clamping block by rotating the active clamping handle to a horizontal position, thereby achieving a fixing effect on the cover glass, keeping the touch screen exposed to the outside, and facilitating the use of the operator.

[0013] Furthermore, it also includes indicator lights and information boards. A row of indicator lights are installed at the upper front side of the movable door, and an information board is installed at the lower side of each indicator light. The indicator lights are used to display the operating status of the equipment in the cabinet, making it easier for the staff to observe the operating information of the power distribution cabinet. The information board is used to identify the function or component corresponding to each indicator light.

[0014] Furthermore, it also includes a hand handle and a waterproof plug. The hand handle is fixedly connected to the middle of the right side of the movable door, a lock is embedded and installed at a position adjacent to the lower end of the hand handle, and a waterproof plug is plugged at the front end of the lock installation hole.
