Description

A marine park power transmission cable protection device

Technical Field

The invention relates to the technical field of cable laying equipment, and in particular to a protective device for power generation and transmission cables in an ocean park.

Background Art

In marine parks, cables are usually needed to transmit electricity. Due to the laying of lines, cables need to be installed in the ocean and on land. Cables on land are generally installed overhead to protect the cables and prevent them from falling.

Existing cable protection devices have limitations. Specifically, for example, the Chinese patent with publication number "CN114899771A" discloses "a cable anti-fall protection device, including multiple support components and anti-fall components, multiple support components are arranged in sequence for use, the anti-fall components are arranged between adjacent support components, the anti-fall components include a ring and a connecting rope, one end of the connecting rope is connected to the ring, and the other end of the connecting rope is connected to the support component, and the cable between adjacent support components can pass through the ring." Although this patent can achieve the effect of preventing the outer insulation layer of the cable from rupturing within a certain range, since the cable is mostly reserved for length when it is installed outdoors, the cable will not be completely straightened to prevent the cable from being damaged. To cope with the thermal expansion and contraction reaction, when the cable is straightened by the connecting rope and the ring, the connecting rope itself cannot always remain straightened, and the rope is easily broken due to wind and sun, which will directly cause the ring to fall, eventually causing the cable to fall between two adjacent support components, causing the cable to be scratched by the edge corners of the support component, resulting in external rupture of the cable; and, the setting of the ring requires that the initial end of the cable be passed through the ring before it can be used, so that the overall device can only be used when the cable is first installed. When the cable is installed and it is necessary to strengthen the overhead protection of the cable at a certain point on the cable, the device loses its installation effect; and, the device cannot adjust the use angle, and its use is limited.

Therefore, the present invention proposes a marine park power generation transmission cable protection device.

In this embodiment, a plurality of limit holes are opened on the top of the adjusting disk 38, and a reserved hole is opened on the inner bottom of the connecting frame 31. In the initial state, one end of the limit rod three 37 is fitted with the top of the adjusting disk 38, and the limit rod three 37 is adaptively matched with the limit hole and the reserved hole respectively.

The adjusting plate 38 cooperates with the limiting rod 37 so that the position of the connecting frame 31 can be fixed and limited after adjustment.

In this embodiment, an anti-scratch component three is provided at the other end of the skateboard 35.

The fixed rods 39 are fixedly connected to the skateboard 35, and the protective rollers three 310 are rotatably connected to the fixed rods 39.

The protective roller 310 protects the outer top of the cable and can also cooperate with the threaded rod 34 to limit the height of the cable inside the main frame 1.

In this embodiment, an auxiliary support structure 4 is provided at the bottom of the mounting base 32, and the auxiliary support structure 4 includes a fixing plate 41, and the fixing plate 41 is fixedly installed at the bottom of the mounting base 32. A storage rack 42 is fixedly installed on one side of the bottom of the fixing plate 41, and a support rod 43 is fixedly installed on the top of the storage rack 42. A support plate 44 is rotatably provided on the inner side of the storage rack 42, and one end of the support plate 44 is connected to a bottom plate 45, and the bottom plate 45 is fixedly connected to the bottom of the two hollow arc plates 22.

The auxiliary support structure 4 further enhances the working stability of the device, and can cooperate with the connecting frame 31 to perform synchronous rotation support work.

In this embodiment, one end of the support rod 43 is rotatably connected to the bottom of the connecting frame 31, and the mounting base 32 is in a "T" shape.

The support rod 43 has the effect of reinforcing the bottom of the connecting frame 31 .

In this embodiment, an installation component is provided on the other side of the bottom of the second fixing plate 41, and the installation component consists of a T-plate 46 and a plurality of expansion screws 47. The T-plate 46 is fixedly connected to the second fixing plate 41, and the expansion screws 47 are connected to the T-plate 46 through threads.

The expansion screw 47 cooperates with the T-plate 46 to enhance the stability of the device.

It should be noted that the present invention is a marine park power transmission cable protection device. Before use, the mounting base 32 and the T-plate 46 are installed at a suitable outdoor position through a plurality of expansion screws 1 33 and expansion screws 2 47. After the plurality of devices are installed, they are used in conjunction with each other.

Remove the two bolt fixings 215. At this time, the limiting rod 1 211 and the limiting rod 212 are free from restriction, and the movable plate 210 is pulled to slide to a suitable position in the opposite direction of the mounting base 32. At this time, the cable is placed on the movable plate 210. After the cable is placed, the movable plate 210 is pushed to the initial position, and the limiting rod 212 is fixed by the bolt fixings 215. After the limiting rod 1 211 is adjusted to a suitable position according to the width of the cable on the movable plate 210, the limiting rod 1 211 is fixed by the bolt fixings 215. At this time, the protective roller 1 213 is attached to the outside of the cable;

After placing the cable on the movable plate 210 and fixing the limit rod 1 211 and the limit rod 212, since the limit rod 37 is in the initial state, one end of the limit rod 37 is in contact with the top of the adjustment disk 38. At this time, the connecting frame 31 is not restricted in the movable state. According to the direction of the cable and the height of the cable inside the main frame 1, the connecting frame 31 is rotated to a suitable angle, and then the threaded rod 34 is rotated to slide the slide plate 35 toward the bottom of the inner side of the connecting frame 31 to a suitable position, so that the connecting frame 31 is limited and fixed by the limit rod 37 and the protective roller 310 can be in contact with the outer surface of the cable inside the main frame 1 to restrict it.

During the process, the slide plate 35 moves synchronously with the two fixing rods 39, the two protection rollers 310, the fixing plate 1 36 and the limiting rod 37, so that the limiting rod 37 gradually moves toward the limiting hole corresponding to the adjusting disk 38 and the reserved hole of the connecting frame 31. When the outside of the protection roller 310 fits the outer surface of the cable inside the main frame 1, the threaded rod 34 stops rotating. At this time, the limiting rod 37 passes through the limiting hole corresponding to the adjusting disk 38 and the reserved hole of the connecting frame 31, and finally the limiting rod 37 limits and fixes the position of the connecting frame 31, and at the same time, the protection roller 310 limits the height of the cable inside the main frame 1.

When the connecting frame 31 rotates, the two hollow arc plates 22 move with it, and the hollow arc plates 22 move with the bottom plate 45, and the bottom plate 45 acts on one end of the support plate 44 to move synchronously, and the other end of the support plate 44 rotates on the inner side of the storage rack 42 as the connecting frame 31 rotates, so that the auxiliary support structure 4 strengthens the support force of the device as a whole;

When the cable is installed, when the cable is affected by thermal expansion and contraction or shakes due to external factors such as wind, the cable acts on the buffer roller 28. Under the pressure of the cable, the buffer roller 28 moves with the connecting rod 27 and the slider 25 corresponding to the connecting rod 27. When the cable is affected by the shaking and generates a downward pressure, the slider 25 slides on the arc slide bar 24 toward the fixed block 23. At the same time, the slider 25 acts on the spring 26 to be compressed toward the fixed block 23. When the spring 26 is compressed to a certain extent and the downward pressure on the cable is reduced, the spring 26 rebounds with the slider 25, so that the buffer roller 28 acts on the cable to move back. During the process, the protective roller 1 213 has an anti-scratch effect on the outer sides of the cable, the buffer roller 28 and the protective roller 217 have an anti-scratch effect on the outer bottom of the cable, and the protective roller 3 310 has an anti-scratch effect on the outer top of the cable.
