Description
Technical Field
[0001] The utility model relates to the technical field of protection devices, and more specifically, to a high-voltage fuse protection device. Background Art
[0002] A high-voltage fuse, also known as a fuse switch, is an important short-circuit protection device mainly used to protect the high-voltage parts of substations, distribution rooms and various electrical equipment.
[0003] The high-voltage fuse is generally installed on transformers and voltage towers and requires manual installation. The installer needs to climb to a high place for operation. Therefore, the high-voltage fuse needs to be placed in a backpack carried with him. However, the existing backpack structure is relatively simple and cannot effectively prevent collisions during climbing. Collisions are likely to damage the high-voltage fuse in the bag, and the protection performance is poor. In view of this, we propose a high-voltage fuse protection device. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a high-voltage fuse protection device to solve the technical problem that the current storage backpack has poor protection performance and is easy to damage the high-voltage fuse.
[0005] To solve the above technical problems, the utility model provides the following technical solution: A high-voltage fuse protection device includes an outer frame, a storage box, an inner box and a middle plate. There are two outer frames in total, and the two sides of the two outer frames are connected by canvas. An assembly groove is opened on the outer side of the outer frame. The inner box is installed in the assembly groove. Side grooves are equidistantly opened on the outer side of the inner box. The storage box is located in the side grooves, and the lower end of the storage box is rotatably connected to the lower side of the side groove opening through a hinge. A plurality of limiting strips are annularly and evenly distributed inside the storage box, and a fuse body is inserted between the limiting strips. Suspension rings are fixed at both ends of the upper end surface of the inner box. A fixing plate is fixed at the lower end inside the outer frame, and the fixing plate is located below the inner box. The middle plate is located between the two fixing plates. A screw rod is rotatably installed at the middle of the middle plate. Limiting plates are installed through both ends of the middle plate. A threaded hole is opened at the middle of the inner side of the fixing plate.
[0006] When the utility model is in use, the buckles at both ends of the bag strap are connected to the suspension rings on both sides, and the device is carried obliquely on the back through the bag strap. During the climbing process, the outer frame and the assembly groove are used for protection to prevent the internal fuse body from being damaged by collision and extrusion. When in use, the storage box is deflected outward from the pulling groove to open the storage box, and the fuse body can be taken out by pulling upward. It is stored in a deflected manner, which is convenient for opening and taking, reducing the difficulty of high-altitude operation. Rotating the rotating cylinder on the middle plate drives the screw rod to rotate, and the screw rod drives the two fixed plates to expand through threads. The displacement of the fixed plates adjusts the distance between the two outer frames. At this time, large-sized tool accessories can be stored in the space between the outer frames. The protection device has an adjustable storage function, which is convenient for carrying tools and enhances the practicability of the device.
[0007] Preferably, fixing bolts are threadedly installed through both sides of the outer frame, and the bottom of the fixing bolts is threadedly connected to the side of the built-in box. The built-in box is locked by the fixing bolts, and the threaded connection is convenient for disassembly.
[0008] Preferably, a limiting block is fixed at the inner bottom end of the side groove, and the limiting block corresponds to the inner end part of the storage box after it is unfolded. During the unfolding process of the storage box, the unfolding angle of the storage box is limited by the limiting block.
[0009] Preferably, a magnetic buckle is provided at the upper end of the storage box, and the magnetic buckle is adsorbed on the top of the side groove when the storage box is closed. A pulling groove is opened at the upper end of the opening of the side groove, and the pulling groove corresponds to the top of the storage box. During the closing process, the storage box is positioned and closed by the adsorption of the magnetic buckle.
[0010] Preferably, a rotating cylinder is sleeved and fixed at the middle of the screw rod, and the rotating cylinder is adapted to the through groove opened at the middle of the middle plate. Manually rotating the rotating cylinder drives the screw rod to rotate.
[0011] Preferably, a positive thread and a reverse thread are respectively opened at both ends of the screw rod, and the positive and reverse threads are respectively connected to the screw holes of the corresponding fixed plates. When the screw rod rotates, the corresponding fixed plates are driven by the threads, so that the two fixed plates are displaced relatively.
[0012] Preferably, limiting grooves are opened at both inner ends of the fixed plate, and the outer ends of the limiting plates are inserted into the corresponding limiting grooves. The displacement is limited by the cooperation of the limiting grooves and the limiting plates to maintain its stability. At the same time, the gap is blocked to facilitate tool storage.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model designs an inner box, buckles the two ends of the bag strap to the suspension rings on both sides, slings the device obliquely on the back through the bag strap, and protects it through the outer frame and the assembly groove during the climbing process to prevent the internal fuse body from being damaged by collision and extrusion. When in use, deflect the storage box outward from the pulling groove to open the storage box, and then pull it upward to complete the extraction of the fuse body. The storage is carried out by deflection, which is convenient for opening and taking, and reduces the difficulty of high-altitude operation.
[0015] 2. The utility model also designs a middle plate. Rotating the rotating cylinder on the middle plate drives the screw rod to rotate, and the screw rod drives the two fixed plates to expand through threads. The displacement of the fixed plates adjusts the distance between the two outer frames. At this time, large-sized tool accessories can be stored in the space between the outer frames. The protection device has an adjustable storage function, which is convenient for carrying tools and enhances the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
