Description

Technical Field

[0001] This utility model relates to the field of power installation equipment technology, and in particular to a line safety isolator. Background Technology

[0002] Line safety isolators are common devices in power or communication systems used to ensure the safety of line maintenance or operation. They typically require external cables to be connected to the internal components. Existing line safety isolators lack mechanisms for securing cables, making them inconvenient for workers to install quickly as needed. Furthermore, the heat dissipation structure within the existing isolator enclosure is often poorly designed, making it difficult for cool air to effectively flow through all heat-generating components. This can lead to heat accumulation in localized areas, resulting in low overall heat dissipation efficiency and potentially affecting the stable operation and lifespan of the equipment.

[0003] Therefore, this application provides a line safety isolator to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a line safety isolator, which aims to solve the problems of existing line safety isolators that lack a mechanism for fixing cables, making it inconvenient for staff to install them quickly as needed. The heat dissipation structure inside the existing isolator box is often not optimized enough, making it difficult for cold air to flow effectively through all heat-generating components, which can easily lead to heat accumulation in local areas and low overall heat dissipation efficiency, potentially affecting the stable operation and service life of the equipment.

[0005] To achieve the above objectives, this application provides the following technical solution: a line safety isolator, including an isolating box body, the isolating box body further including a base plate and a box cover, the base plate and the box cover are hinged together, the box cover is provided with a cooling fan and a locking mechanism for connecting the base plate, the base plate is connected with a fixing plate and a mounting plate, the mounting plate is provided in two sets, the two sets of mounting plates are set on the base plate on the upper and lower sides of the fixing plate, the fixing plate is connected with multiple sets of isolator bodies for line safety, a wire plate is slidably connected to the mounting plate, the mounting plate is provided with a sliding groove, a pressing slider slides in the sliding groove, a guide groove connecting to the outside is provided on the side wall of the sliding groove, the wire plate slides through the sliding groove in the guide groove, through the cooperation between the above components, the cable can be fixed and the heat dissipation and air circulation can be improved, thereby improving the overall integration, installation flexibility and operational reliability of the equipment.

[0006] Preferably, the cover is also equipped with a diverter plate and a guide plate. The air cooler is installed on the outer side wall of one side of the cover, and the diverter plate is connected to the inner side wall of the other side of the cover. The cover has ventilation openings, which are located on the same side wall as the air cooler. There are two sets of ventilation openings, which are located on the upper and lower sides of the air cooler, respectively. By setting the diverter plate and guide plate inside the cover and rationally arranging the positions of the air cooler and the ventilation openings, the air circulation path inside the cover is optimized.

[0007] Preferably, the air cooler, the fixed plate, and the diverter plate are located at the same height. There are two sets of guide plates, which are symmetrically arranged on the upper and lower sides of the diverter plate. The height of the guide plates is matched with that of the vent, ensuring that the cold air can effectively cool the main heat-generating components first and guide the airflow direction.

[0008] Preferably, a wire clamp is connected to one side of the wire plate, and a locking block is connected to the other side of the wire plate by bolts. Both the wire plate and the locking block have threaded holes of the same size. The wire plate and the locking block are connected by bolts. The size of the locking block is adapted to the slide groove. By setting the wire clamp and the locking block connected by bolts, not only can the cable be reliably fixed, but the wire plate can also be firmly locked in the slide groove of the mounting plate.

[0009] Preferably, the top-tightening slider further includes a base plate and a top-tightening plate. An elastic telescopic rod is fixedly connected to the base plate, and the telescopic end of the elastic telescopic rod is rotatably connected to the top-tightening plate. By setting a top-tightening slider with an elastic telescopic rod and a top-tightening plate, a certain pre-tightening force can be provided to the wire plate before final locking to prevent it from sliding easily and facilitate fine-tuning operations.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, by setting a wire plate that can slide on the mounting plate, and cooperating with a top-tightening slider and a locking block structure, the wire plate used to fix the cable can be easily slid and adjusted on the mounting plate to achieve initial positioning and final locking. This solves the problems of inconvenient cable fixing and difficulty in accurately adjusting the position in the prior art, and improves the convenience and flexibility of installation.

[0012] In this invention, by setting up a cooler, a diverter plate, and a guide plate, a specific cool air circulation path is constructed, which can guide the cool air to cool the isolator body first, then divert and guide it to the circuit board and cable connection area, and finally exhaust it from the vent. This solves the problems of uneven heat dissipation and local heat accumulation in the prior art, improves the overall heat dissipation efficiency and uniformity of the isolation box, and ensures the stable and reliable operation of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] refer to Figure 1-5The diagram shows a line safety isolator, including an isolating box body 1. The isolating box body 1 also includes a base plate 2 and a box cover 3, which are hinged together. The box cover 3 is equipped with a cooling fan 4 and a locking mechanism for connecting the base plate 2. A fixing plate 6 and a mounting plate 7 are connected to the base plate 2. Two sets of mounting plates 7 are provided, which are disposed on the upper and lower sides of the base plate 2 of the fixing plate 6. Multiple sets of isolator bodies 5 for line safety are connected to the fixing plate 6. To facilitate easier and faster cable fixing, a cable plate 8 is slidably connected to the mounting plate 7. A groove 71 is provided on the mounting plate 7, and a clamping slider 9 slides within the groove 71. A groove is provided on the side wall of the groove 71. The guide groove 72 connects to the outside world. The wire plate 8 slides through the slide groove 71 within the guide groove 72. One side of the wire plate 8 is connected to the wire clamp 82, and the other side of the wire plate 8 is connected to the locking block 81 by bolts. The locking block 81 and the wire plate 8 have threaded holes of the same size. The length of the locking block 81 is adapted to the size of the slide groove 71, and the width of the locking block 81 is adapted to the guide groove 72. In order to prevent the wire plate 8 from sliding easily on the mounting plate 7 and to facilitate fine adjustment of the position of the wire plate 8 on the mounting plate 7, the top-tightening slider 9 also includes a base plate 91 and a top-tightening plate 93. An elastic telescopic rod 92 is fixedly connected to the base plate 91, and the telescopic end of the elastic telescopic rod 92 is rotatably connected to the top-tightening plate 93.

[0022] As one embodiment of this invention, to improve the air circulation effect inside the housing, a diversion plate 31 and a guide plate 32 are also provided inside the housing cover 3. The air cooler 4 is installed on the outer side wall of one side of the housing cover 3, and the diversion plate 31 is connected to the inner side wall of the other side of the housing cover 3. The air cooler 4, the fixing plate 6, and the diversion plate 31 are located at the same height. When the housing cover 3 is closed with the base plate 2, the isolator body 5 is located between the air cooler 4 and the diversion plate 31. The cold air drawn in by the air cooler 4 first circulates through the isolator body 5. To cool down the air, the cover 3 has ventilation openings on the same side wall as the air cooler 4. There are two sets of ventilation openings, located on the upper and lower sides of the air cooler 4 respectively. There are also two sets of guide plates 32, which are symmetrically arranged on the upper and lower sides of the diversion plate 31. The height of the guide plates 32 is matched with that of the ventilation openings. Under the action of the diversion plate 31, the cold air is diverted to the upper and lower sides, and then, under the action of the guide plates 32, it flows back to the air outlet. Along the way, it passes through the wire plate 8, which carries away the hot air near the wire plate 8.

[0023] The working principle of this practical device is as follows: First, the operator installs the isolator body 5 onto the fixing plate 6. Then, the clamping slider 9 is placed in the slide groove 71. Next, the locking block 81 on the wire plate 8 is aligned vertically with the guide groove 72. The locking block 81 is then inserted into the guide groove 72, contacting the clamping slider 9. The locking block 81 pushes the clamping plate 93 towards the base plate 91. After the locking block 81 is fully positioned within the slide groove 71, it is rotated to rotate the clamping plate 93. The wire plate 8 can then be released. Under the action of the elastic telescopic rod 92, the clamping plate 93 initially fixes the wire plate 8 onto the mounting plate 7, facilitating wiring and fine-tuning. Then, the cable connected to the isolator body 5 is fixed to the clamp 82. After fixing, the bolts on the plate 8 are rotated to clamp the mounting plate 7 with the clamp 81, so that the plate 8 is firmly fixed on the mounting plate 7. Then the box cover 3 can be closed. Then the air cooler 4 is turned on to blow cold air into the isolation box body 1. The cold air drawn in by the air cooler 4 first cools the isolator body 5. Then, under the action of the diverter plate 31, the cold air is diverted to the upper and lower sides. Then, under the action of the guide plate 32, it flows back to the air outlet. Along the way, it passes the plate 8, which carries away the hot air near the plate 8, improving the air circulation effect inside the isolation box body 1.
