DETAILED DESCRIPTION
[0020] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is combined with the drawings and example, and the utility model is further detailedly explained. It should be understood that the specific example described here is only used to explain the utility model, and does not limit the utility model.
[0021] As Figure 1 And Figure 2As shown, the protection device is mainly composed of a box body 1 and a drawer box 2. The box body 1 is designed as a structure with a right-angled triangular cross section, making the space utilization of the box body 1 more efficient. The box body 1 is composed of a bottom plate 1.1, an inclined plate 1.3, a side plate, two side plates 1.2 and a plurality of emission holes 3. The bottom plate 1.1, the inclined plate 1.3 and the side plate are rectangular plates with equal lengths, the two side plates 1.2 are right-angled triangular plates with the same area, the lengths of the two right-angled sides of the right-angled triangular plate are respectively the widths of the bottom plate 1.1 and the side plate, and the length of the hypotenuse of the right-angled triangular plate is the width of the inclined plate 1.3. The bottom plate 1.1, the inclined plate 1.3, the side plate and the two side plates 1.2 constitute the box body 1 with a right-angled triangular cross section. The bottom plate 1.1, the inclined plate 1.3, the side plate and the two side plates 1.2 are made of plate materials, without the need for special molds to manufacture each plate, saving costs, suitable for small-scale production, and can easily change the size and shape, reducing production costs and improving production efficiency. The inclined plate 1.3 is provided with the drawer box 2, and the drawer box 2 is designed as a structure that can be easily pulled out and pushed back, greatly simplifying the drawer box replacement process. This drawer design allows users to quickly access the drawer box 2 without the need to disassemble or move the box body 1, thereby saving valuable time and labor. The inclined surface 2.4 of the drawer box 2 coincides with the surface of the inclined plate 1.3 of the box body 1, forming a smooth transition between the drawer box 2 and the box body 1, not only maintaining consistency in appearance, but also ensuring the stability of the drawer box 2 in function. The upper and lower bottom surfaces 2.7 are respectively provided with a first opening 2.2 and a second opening 2.3, and the first opening 2.2 and the second opening 2.3 are connected with an inner inclined plate 2.1. This design not only makes the drawer box replacement convenient and fast, but also effectively improves the air flow efficiency by setting a round hole on the inclined surface 2.4 of the drawer box 2. The triangular structure of the box body 1 not only has high stability, but also is easy to process and install. And improve the versatility, you can also use the box body 1 by sticking the inclined plate 1.3 of the box body 1 together, thereby adapting to different sizes of tower shape. Traditionally, protective equipment for power transmission line towers often needs to be accurately measured and customized according to different tower types. However, this process not only consumes time and effort, but also greatly increases production costs. The utility model realizes the versatility across tower types through innovative design. This means that regardless of the specific model or voltage level of the tower, the protection device can effectively adapt, eliminating the need for precise customization for each tower type, thereby avoiding the cumbersome measurement and customization process. This universal design not only improves production efficiency, but also significantly reduces the production cost of measurement and mold making, providing a more economical and efficient solution for the maintenance of power transmission lines.
[0022] As Figure 1As shown, the box 1 includes a bottom plate 1.1, an inclined plate 1.3, and two side plates 1.2 on both sides. These plates form a triangular cross-section box 1. This triangular design not only provides additional stability, but also makes the box 1 more flexible in spatial layout. The design of the inclined plate 1.3 and the side plate 1.2 of the box 1 allows the box to be stacked horizontally. By overlapping the inclined plate 1.3 or the side plate 1.2, the length and width of the box can be flexibly expanded. This design allows the box 1 to quickly and easily adjust its size according to different usage requirements and space limitations, greatly improving its applicability and versatility. In addition, the stacking design of the box 1 also brings advantages in logistics and storage. During transportation, the box can reduce the occupied space by stacking, thereby reducing transportation costs. When warehousing, stacked boxes 1 can make more efficient use of warehouse space, reducing storage costs. This design not only improves logistics efficiency, but also saves valuable space resources. For example, when the area needs to be expanded, it can be easily achieved by simply increasing the number of boxes. This modular design allows the box 1 to easily adapt to various towers. Each plate has a number of emission holes 3 along the entire length of the plate edge, which are linearly distributed. The emission holes 3 are circular holes. This design enhances air flow, as the presence of emission holes 3 allows air to enter and exit the box 1 more freely, effectively reducing internal temperature and reducing heat accumulation. With linearly distributed emission holes 3, this distribution ensures more uniform air flow, avoiding congestion in local areas, thereby ensuring uniformity and comfort of the entire box 1 internal environment. It also increases the ventilation of the box 1, which helps maintain dryness inside the box and helps prevent moisture and mold growth. This extends the service life of the protection device, reduces replacement frequency, and further reduces operating costs. The emission hole 3 design of the present utility model has the effect of preventing water accumulation and water resistance. These circular holes ensure that rainwater and moisture can be easily drained, avoiding accumulation inside the protection device, thereby protecting the interior from moisture and preventing corrosion or damage to the box 1 caused by water accumulation. This design improves efficiency while extending the service life of the protection device.
[0023] As Figure 2 and Figure 3As shown, in the long-term protection process, the protection device may be partially damaged and needs to be replaced regularly to ensure continuous protection effect. The traditional method often needs to disassemble the entire protection device to carry out maintenance and replacement of the repellent, which not only is cumbersome to operate, but also increases the safety risk. The drawer box 2 is ingeniously designed, so that the user only needs to easily pull open the drawer to replace the work. This design not only simplifies the replacement process, improves the operation convenience, but also reduces the safety risk in the maintenance process, providing a strong guarantee for the safe and stable operation of the power transmission line. The drawer box 2 is the core component of the utility model, which is designed to be easily pulled out from the inclined plate 1.3 of the box body 1. The cross section of the drawer box 2 is a right trapezoid, including an inclined surface 2.4, two inner side plates 2.5, an inner inclined plate 2.1, an upper bottom surface 2.6 and a lower bottom surface 2.7. The width of the inclined surface 2.4 is the same as that of the upper bottom surface 2.6 and the lower bottom surface 2.7, and the inclined surface 2.4 shares a bottom edge and a top edge with the upper bottom surface 2.6 and the lower bottom surface 2.7 respectively. The two inner side plates 2.5 are arranged in the middle of the upper bottom surface 2.6 and the lower bottom surface 2.7 and on the two side edges of the upper bottom surface 2.6 and the lower bottom surface 2.7. The design of the two inner side plates 2.5 enhances the lateral stability of the drawer box 2, and also provides additional support for the drawer box 2 to prevent deformation during pulling out. The upper bottom surface 2.6 and the lower bottom surface 2.7 of the drawer box 2 are respectively provided with a first opening 2.2 and a second opening 2.3. This design allows the upper bottom surface 2.6 and the lower bottom surface 2.7 of the drawer box 2 to interact with the external environment, providing more flexibility and convenience. The first opening 2.2 on the surface of the upper bottom surface 2.6 of the drawer box 2 is rectangular in shape and located at the top end of the drawer box 2. The top edge of the first opening 2.2 coincides with the bottom edge of the inclined plate 1.3 of the box body 1, and the two side edges of the first opening 2.2 coincide with the side edges of the two inner side plates of the drawer box 2. This precise alignment ensures the sealing between the drawer box 2 and the box body 1, and also facilitates the replacement of the drawer box. The second opening 2.3 on the surface of the lower bottom surface 2.7 of the drawer box 2 is rectangular in shape and located at the top end of the drawer box 2. The top edge of the second opening 2.3 coincides with the top edge of the inclined plate 1.3 of the box body 1, and the two side edges of the second opening 2.3 coincide with the side edges of the two inner side plates of the drawer box 2. This design makes the structure of the protection device more compact and simple, reduces the waste of space, and also facilitates management and storage. The compact design means that the space inside the box body 1 can be used more efficiently, and the simple structure reduces the complexity of manufacturing and maintenance. The inner inclined plate 2.1 is arranged between the top edge of the first opening 2.2 and the bottom edge of the second opening 2.3. This design increases the structural stability of the drawer box 2, prevents the drawer box 2 from deforming during use, and ensures the durability and reliability of the drawer box 2. The design of the inner inclined plate 2.1 not only enhances the structural stability of the drawer box 2, but also forms an effective waterproof barrier by combining with the inclined plate 1.3, protecting the interior of the drawer box from moisture.The top edge of the inner inclined plate 2.1 coincides with the bottom edge of the inclined plate 1.3, which effectively prevents rainwater from entering the repellent placement 2.8, improving the stability of the device. The design of the inner inclined plate 2.1 enhances the structural stability of the drawer box 2, and this waterproof design is particularly suitable for outdoor environments, which can protect the device from harsh weather conditions and ensure the long-term effectiveness of the device to maintain the power tower. The first opening 2.2 and the space formed by the inner inclined plate 2.1 and the two inner plates and the lower bottom surface 2.7 of the drawer box 2 form the repellent placement 2.8. Each face of the drawer box 2 is provided with two emission holes 3, which are used to increase the efficiency of air flow.
