Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to an energy metering box with protective functions. Background Technology

[0002] A power metering box is a collection of necessary metering instruments and auxiliary equipment for measuring electrical energy. It includes electricity meters, voltage and current transformers and their secondary circuits, power metering panels, cabinets, and boxes. Metering boxes can be installed in a suspended or floor-mounted manner. The most traditional problems with power metering boxes are heat dissipation and dust prevention. Transmission-type power metering boxes have poor sealing effects and relatively simple locking functions. This results in dust entering the box despite its tight seal, affecting the normal operation of electrical equipment. Furthermore, the ventilation of existing distribution boxes is limited to a single hole, which has no dust-blocking effect and poor heat dissipation, affecting the normal operation of the power metering box.

The forward winch 2041 and... The inner ring of the reverse winch 2042 is provided with a ratchet ring 20814, which meshes with the ratchet 2081. When the second servo motor 204 rotates in the forward direction, the ventilation plate 1061 is pulled down. At this time, the vertical surface of the ratchet teeth 20812 of the ratchet 2081 in the middle of the bearing seat 208 of the forward winch 2041 will hinge to the vertical surface of the inner teeth of the ratchet ring 20814 of the forward winch 2041. At this time, the forward winch 2041 and its ratchet 2081 rotate in the same direction. A second spring 20813 is arranged between the bottom of the ratchet teeth 20812 and the spring space 20811 for the springback of the ratchet teeth 20812. At the same time, the traction cable 10611 of the reverse winch 2042 is pulled by the ventilation plate 1061 to the unwinding state.The reverse winch 2042 rotates in the opposite direction to the ratchet 2081 it is located in. At this time, the inclined surface of the inner teeth of the ratchet ring 20814 of the reverse winch 2042 contacts the inclined surface of the ratchet teeth 20812 of the ratchet 2081. After pressing down the ratchet teeth 20812, it springs back, completing the rotation action of releasing the rope. When the ventilation plate 1061 is raised, the actions of the forward winch 2041 and the reverse winch 2042 are opposite. Guide wheels 205 are arranged on the side wall and bottom of the housing 2, and the traction cable 10 611 is attached to the side wall and bottom of the housing 2 via guide wheel 205. A brake box 206 is located on the inner side wall of the housing 2. A traction cable 10611 connected to the reverse winch 2042 passes through the brake box 206. A limiting tube 2061, which is a hollow frustum, is located inside the limiting tube 2061. A brake tube 2062, also hollow frustum, is movably mounted inside the limiting tube 2061. The front of the brake tube 2062 is divided into equal subdivisions. The front diameter of brake pipe 2062 is larger than the inner front diameter of limiting pipe 2061. A servo cylinder 2063 is located behind brake pipe 2062. Servo cylinder 2063 drives and connects to brake pipe 2062. Servo cylinder 2063 and limiting pipe 2061 are located on the inner wall of housing 2. Traction cable 10611 passes through limiting pipe 2061 and brake pipe 2062. When ventilation plate 1061 is pulled to a certain height, brake pipe 2062 moves forward and inserts into limiting pipe 2061. The traction cable 10611 is clamped at the front of the 062 section to prevent it from descending due to the weight of the ventilation plate 1061. During operation, the brake pipe 2062 moves backward to release the brake on the traction cable 10611. A guide roller 207 is rotatably installed at the upper corner of the housing 2, located between the slide rails 106, to support the ventilation plate 1061 at the corner. The operation of the second servo motor 204 can be determined by the temperature controllers located inside the housing 2.

[0032] The design allows for the installation and support of power distribution components by mounting beams between the two side walls of the enclosure, and the power supply function involved in the design is an external power supply.

[0033] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
