[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The present invention provides Figures 1-10 The shown overhead cable protection device comprises an upper protective cover 1 and a lower protective cover 2. The upper protective cover 1 and the lower protective cover 2 form a "C"-shaped structure. A fixed plug-in block 3 is fixedly installed at the bottom of the upper protective cover 1, and a fixed slot 5 is provided at the top of the lower protective cover 2. The fixed plug-in block 3 and the fixed slot 5 are adapted to each other. A card slot 4 is provided on the left and right sides of the fixed plug-in block 3 near the bottom position. A spring 6 is fixedly connected to the left and right sides of the fixed slot 5. One end of the spring 6 is connected to a card block 7. The card block 7 is triangular, and the bottom of the card block 7 is set as an inclined surface. The inside of the card slot 4 is provided with an inclined surface adapted to the bottom of the card block 7. An upper fixed plate 9 and a lower fixed plate 10 are provided inside the upper protective cover 1 and the lower protective cover 2. A buffer structure 8 is provided between the upper fixed plate 9 and the lower fixed plate 10. The buffer structure 8 is used to absorb cable vibration. Adjustment structures 11 are provided on both sides of the upper protective cover 1 and the lower protective cover 2. The adjustment structure 11 is used to prevent rainwater from entering the interior of the protective device. Furthermore, the adjustment structure 11 includes an adjustment shield 1101, and there are multiple adjustment shields 1101. Through slots 1102 are provided on both sides of the upper protective cover 1 and the lower protective cover 2. Four fixed bases 1103 are fixedly installed inside the lower protective cover 2. The fixed bases 1103 are evenly distributed inside the lower protective cover 2. A rotating shaft 1104 is rotatably installed on every two bases 1103. The rotating shaft 1104 is provided with a thread 1106. The adjustment shield 1101 is threadedly installed on the rotating shaft 1104. A bevel gear 1105 is fixedly installed at one end of the rotating shaft 1104. A second rotating shaft 1108 is provided inside the cover 2, and both ends of the second rotating shaft 1108 are rotatably mounted on the inner wall of the lower protective cover 2. A second bevel gear 1107 is fixedly mounted on the second rotating shaft 1108 near both ends. The second bevel gear 1107 is meshed and transmission-connected with the first bevel gear 1105. A motor 1109 is fixedly mounted on the inner wall of the lower protective cover 2, and the motor 1109 is drive-connected to one of the first rotating shafts 1104. A raindrop sensor and a temperature sensor are installed on the upper protective cover 1. One end of the raindrop sensor and the temperature sensor are respectively connected to a controller, which controls the start and stop of the motor 1109. In the embodiment of the present invention, the electrodes of the raindrop sensor are mounted on the surface of the upper protective cover 1, and rainwater can directly contact the electrodes, thereby forming a path between the electrodes; During installation, align the fixing block 3 at the bottom of the upper protective cover 1 with the fixing slot 5 at the top of the lower protective cover 2 and insert it. When the fixing block 3 is inserted, its side presses the inclined surface of the card block 7, causing the card block 7 to be compressed toward the spring 6 inside the fixing slot 5. When the clamping block 7 is in the position of the clamping block 7, the spring 6 rebounds and pushes the clamping block 7 into the clamping slot 4, thereby fixing the upper protective cover 1 and the lower protective cover 2 together to form a protective space for the cable. The upper protective cover 1 and the lower protective cover 2 adopt the cooperation mode of the fixed plug 3 and the fixed slot 5 and the clamping block 7 and the clamping slot 4. The installation process is simple and fast, and no complicated tools are required. The upper protective cover 1 only needs to be aligned with the lower protective cover 2 and inserted to complete the installation, which greatly improves the installation efficiency, especially when it is necessary to install a protective device for long-distance overhead cables, which can save a lot of time. The clamping block 7 is clamped into the clamping slot 4 under the action of the spring 6, forming a reliable locking structure, which can prevent the protective cover from accidentally falling off when subjected to external forces such as wind and vibration, thereby ensuring continuous protection of the cable. At the same time, this connection method is easy to disassemble while ensuring stability, which is convenient for subsequent maintenance and inspection of the cable. The raindrop sensor and temperature sensor monitor the rainfall in the external environment and the internal temperature of the protective device in real time. The raindrop sensor and temperature sensor send signals to the controller, which starts the motor 1109. The motor 1109 drives the rotating shaft 1104 connected thereto to rotate. Since the bevel gear 1105 on the rotating shaft 1104 meshes with the bevel gear 2 1107 on the rotating shaft 2 1108, the rotating shaft 2 1108 also rotates accordingly. The rotating shaft 1104 and the rotating shaft 2 1108 drive the adjustment shield 1101 to move on one side of the through slot 1102 through the thread 1106. The multiple adjustment shields 1101 can adjust the size of the openings on both sides of the protective cover. When it rains, the sensor controls the adjustment shield 1101 to select the blocking range of the through slot 1102 through the motor 1109 according to the amount of rain. On the one hand, it can prevent a large amount of rainwater from entering the inside of the protective cover from both sides. On the other hand, a small amount of rainwater can be used to clean the cables inside the protective device to avoid excessive dust covering and hindering the normal dissipation of heat. When the rain stops, the motor 1109 rotates in the opposite direction, and the adjustment shield 1101 returns to its initial position to ensure ventilation inside the protective cover. When the temperature sensor detects that the temperature inside the protective device is abnormal, Normally, the controller controls the motor 1109, adjusts the baffle 1101 to adjust the size of the through slots 1102 on both sides of the protective cover, thereby realizing rapid adjustment of the internal temperature; the adjustment structure 11 can automatically adjust the shielding degree of the through slots 1102 according to the rainfall conditions, and close the through slots 1102 in time when the rainfall is heavy, effectively preventing rainwater from entering the interior of the protective cover, avoiding short circuits and other faults of the cable due to moisture, thereby improving the safety and reliability of the cable operation; when the rainfall is less, the shielding degree of the through slots 1102 is controlled, so that a small amount of rainwater enters the interior to clean the cable; at the same time, the adjustment structure 11 can automatically adjust in time according to the temperature inside the protective device, ensuring that the internal cable is always at a suitable working temperature, thereby improving the service life of the cable.

[0030] See also Figure 4-5 In one embodiment of the present invention, the upper fixing plate 9 and the lower fixing plate 10 are semicircular in structure, and a plurality of connecting members 14 are fixedly connected to the inner walls of the upper protective cover 1 and the lower protective cover 2, and the other ends of the connecting members 14 are respectively connected to the upper fixing plate 9 and the lower fixing plate 10; Furthermore, the buffer structure 8 includes a buffer base 801, and there are multiple buffer bases 801. The buffer bases 801 are fixedly mounted on the inner walls of the upper fixed plate 9 and the lower fixed plate 10. Two slide rods 802 are fixedly mounted on each buffer base 801. A second spring 803 is provided on the outer side of the slide rod 802. One end of the second spring 803 is connected to the buffer base 801, and the other end of the second spring 803 is connected to a slider 804. A clamping block 805 is fixedly connected to the side of the slider 804 away from the buffer base 801. The slider 804 is passed through the slide rod 802. In the embodiment of the present invention, a placement hole for installing cables is provided between the upper fixing plate 9 and the lower fixing plate 10, and the clamping block 805 is made of natural rubber with good insulation properties.

[0031] When the cable needs to be installed, the upper protective cover 1 and the lower protective cover 2 are opened first, and the cable is placed between the upper fixing plate 9 and the lower fixing plate 10. At this time, due to the action of the second spring 803, the slider 804 is in the initial position on the slide rod 802, and there is a certain distance between the clamping blocks 805, which is convenient for cable insertion; After the cable is installed, close the upper protective cover 1 and the lower protective cover 2. During the operation of the cable, if vibration occurs, the cable will exert a force on the upper fixed plate 9 and the lower fixed plate 10, and its buffer base 801, slide rod 802, spring 2 803 and slider 804 and other components work together to absorb vibration energy; multiple buffer bases 801 and the double slide rod 802 and spring 2 803 structure on each buffer base 801 enable the entire buffer system to buffer the vibration of the cable from multiple directions and positions. No matter which direction the cable is subjected to vibration, the energy can be absorbed by the buffer structure 8 in a timely and effective manner, reducing the damage to the cable caused by vibration.

[0032] See also Figure 8 In one embodiment of the present invention, a plurality of drain ports 12 are provided at the bottom of the lower protective cover 2 , and the drain ports 12 are evenly distributed on the lower protective cover 2 ; In the embodiment of the present invention, on the one hand, the drain outlet 12 can discharge a small amount of sewage after the rainwater washes the cable out of the interior of the protective device, ensuring the cleanliness of the interior of the protective device; on the other hand, the drain outlet 12 plays an auxiliary heat dissipation role for the protective device.

[0033] See also Figure 9-10 In one embodiment of the present invention, a plurality of baffles 13 are fixedly mounted on both sides of the lower protective cover 2. The baffles 13 are in an "L"-shaped structure and are fixedly mounted near the through slot 1102. The baffles 13 on both sides of the lower protective cover 2 are arranged opposite to each other. In an embodiment of the present invention, when the overhead cable protection device is operating normally and there are no special circumstances such as rainfall, air will naturally flow through the through slots 1102 on both sides of the protective cover. At this time, the baffles 13 with an "L"-shaped structure and arranged opposite to each other will have a certain guiding effect on the airflow. When the airflow enters from the through slot 1102 on one side, the baffle 13 will change the direction of the airflow. Under the guidance of the baffles 13 on both sides, an airflow circulation is formed inside the protective cover. This airflow circulation helps to promote the circulation of air inside the protective cover, enhance the heat dissipation effect, and enable the heat generated by the cable operation to be more effectively dissipated to the surrounding environment.

[0034] See also Figure 4In one embodiment of the present invention, a semi-fastening ring 15 is fixedly installed at both ends of the upper protective cover 1 and the lower protective cover 2, and a buffer pad 16 is fixedly installed on the inner side of the semi-fastening ring 15; Furthermore, a cable hole 17 is provided between the semi-fastening rings 15 at both ends of the upper protective cover 1 and the lower protective cover 2; In an embodiment of the present invention, when installing an overhead cable, the cable is first placed in the cable hole 17 between the semi-fastening rings 15 at both ends of the lower protective cover 2. The size of the cable hole 17 is slightly larger than the outer diameter of the cable to ensure that the cable can pass smoothly; after the cable is placed, the upper protective cover 1 and the lower protective cover 2 are covered, and the buffer pad 16 fits tightly on the surface of the cable. The buffer pad 16 has a certain elasticity and insulation, can adapt to the shape of the cable, and fill the tiny gap between the cable and the semi-fastening ring 15; compared with other fixing methods, the semi-fastening ring 15 has a simple structure and is easy to install, and can quickly and effectively fix the cable, reducing the possibility of the cable shaking and displacement in the protective cover, and reducing the risk of the cable being damaged due to friction or collision with the inner wall of the protective cover.
