Description

Technical Field

[0001] The present invention relates to the technical field of power transmission tower foundation protection, in particular to a rotating floating protection device for a high-voltage transmission line tower foundation. Background Art

[0002] A tower is a pole or tower-shaped structure that supports overhead transmission line conductors and overhead ground wires, maintaining a certain distance between them and the ground. Power towers worldwide are constructed using steel, wood, and reinforced concrete. Wood and reinforced concrete pole-shaped structures are generally referred to as poles, while steel tower-shaped structures and reinforced concrete chimney-shaped structures are referred to as towers. The subsurface portion of a transmission line tower is collectively referred to as the tower foundation. Its function is to stabilize the tower and prevent it from being pulled up, pressed down, or overturned by vertical loads such as ground wires, wind, ice accumulation, and wire breakage tension, as well as horizontal loads and other external forces.

[0003] A search of prior art reveals a tower protection device disclosed in publication number CN208401408U. The device comprises two opposing clamps, each comprising a clamp fixing portion on either side and a clamp protecting portion in the middle. The clamp fixing portions are provided with removable clamp fixings, and the opposing inner surfaces of the clamp protecting portions are shaped to accommodate the outer wall of the tower. The outer surfaces of the clamp fixing portions are each provided with a first fixing ring and a second fixing ring. The first fixing ring is connected to a cable, which is suspended from an anchor. The other end of the cable is provided with a removable cable fixing, which is used to achieve a removable connection with the second fixing ring.

[0004] The reference document describes a removable plywood wrapped around the outer wall of the tower to protect it. Cables are attached to the plywood, and anchors are connected to the cables. The anchors can be driven into the ground based on wind direction to determine their specific anchoring position. This provides strong fixing and provides excellent wind protection. It also isolates the tower from the water during flooding, thus preventing flooding. When the foundation of a tower is submerged in water, it is typically constructed with a circular pile foundation. Circular pile foundations face numerous challenges, including impacts from water flow, collisions with floating objects on the surface, and interference with flood flow.

[0005] In situations like flooding, the impact of water on circular pile foundations can be significant, potentially destabilizing them and jeopardizing the safe operation of power transmission lines. Furthermore, floating objects can directly impact circular pile foundations, posing potential safety risks to transmission lines. Traditional circular pile foundations are unable to adequately address these challenges in the volatile water environment, creating an urgent need for innovative designs to improve the safety and stability of circular pile foundations. Summary of the Invention

[0006] The object of the present invention is to provide a high-voltage transmission line tower foundation rotating floating protection device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a fixed pile, a plurality of installation grooves are provided on the fixed pile, a rotating shaft is fixedly connected to the installation groove, a plurality of limit bars are fixedly connected to the outer side surface of the rotating shaft, the upper and lower ends of the limit bar are fixedly connected to the anti-fall ring, a protection box is slidably connected to the limit bar, a through hole is provided in the middle of the protection box, a plurality of sliding grooves are provided on the inner wall of the through hole, and the sliding grooves are adapted to the limit bar.

[0008] Preferably, the shape of the protection box is diamond-shaped, and adjustment grooves are provided at both ends of the protection box. The cross-section of the adjustment groove is triangular, and the upper end of the adjustment groove passes through the upper surface of the protection box. The upper end of the adjustment groove is movably connected to a sealing cover.

[0009] Preferably, the limiting strip includes a connecting strip, which is fixedly connected to the outer surfaces of multiple rotating shafts, and an arc plate is fixedly connected to the outer side of the connecting strip. The slide groove of the protection box is T-shaped, and the width of the anti-fall ring covers the slide groove of the protection box.

[0010] Preferably, both ends of the protection box are detachably connected with adjustment plates, a plurality of fixing holes are opened on the adjustment plates, fixing screws are passed through the fixing holes, and one end of the fixing screws is threadedly connected to the outer surface of the protection box.

[0011] Preferably, the adjustment plate includes two planar plates, the fixing holes are provided on the planar plates, and a flexible plate is fixedly connected between the two planar plates.

[0012] Preferably, filling rings are provided between the multiple rotating shafts, and support rings are provided above the uppermost rotating shaft and below the lowermost rotating shaft. The outer diameters of the filling rings and the support rings are the same as the outer diameter of the rotating shaft.

[0013] Preferably, the outer surfaces of the two adjustment grooves are provided with observation windows, and the observation windows are provided with scales.

[0014] Compared to existing technologies, the present invention offers the following advantages: by installing a counterweight of a certain weight within the adjustment tank, the protection box can be partially submerged and partially surfaced, effectively protecting the anchor post from surface wave damage. As the water level changes, the position of the protection box adjusts to the water level under the influence of buoyancy, maintaining its protective effect on the anchor post. When the direction of the water flow changes, the impact of the current causes the protection box to rotate. The protection box is connected to the anchor post via a rotating shaft and can rotate freely around the anchor post, with its sharp end facing the direction of the current, thereby reducing resistance. It also guides debris carried by the current away from the anchor post, protecting it. An adjustment plate is installed on the outside of the protection box. By adjusting the angle of two flat plates, the adjustment plate can be adjusted to suit different water flow conditions. This reduces the impact of the current on the anchor post, preventing it from being hit by debris, and extending the life of the anchor post. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 5 , the embodiment provided by the present invention:

[0024] Embodiment: It comprises a fixed pile 1, and a plurality of mounting grooves 2 are provided on the fixed pile 1, a rotating shaft 3 is fixedly connected in the mounting groove 2, and a plurality of limit bars 4 are fixedly connected to the outer side surface of the rotating shaft 3. The limit bar 4 can connect the protection box 6 and the rotating shaft 3 to each other. The upper and lower ends of the limit bar 4 are fixedly connected with an anti-fall ring 5, and the anti-fall ring 5 can prevent the protection box 6 from falling out of the limit bar 4 during the movement. The limit bar 4 is slidably connected to the protection box 6, and a through hole 7 is provided in the middle of the protection box 6. A plurality of slide grooves 8 are provided on the inner wall of the through hole 7, and the slide grooves 8 are adapted to the limit bar 4.

[0025] The protective box 6 is diamond-shaped, adapting to the current and reducing resistance. Adjustment slots 9 are defined at both ends of the box. These slots are triangular in cross-section and extend through the top surface of the box. A sealing cap 10 is movably connected to the slots. Placing a suitable weight in the slots allows the box 6 to float near the water's surface, protecting the pillars from erosion by waves.

[0026] The limiting bar 4 includes a connecting bar 11, which is fixedly connected to the outer surfaces of the multiple rotating shafts 3. A curved plate 12 is fixedly connected to the outer side of the connecting bar 11. The chute 8 of the protective box 6 is T-shaped, and the width of the anti-fall ring 5 covers the chute 8 of the protective box 6. When the protective box 6 rotates, the chute 8 drives the internal curved plate 12 and the connecting bar 11 to rotate synchronously. When the protective box 6 floats up and down, it can move within the constraints of the curved plate 12 to prevent it from falling out.

[0027] Adjustment plates 14 are detachably connected to both ends of the protective box 6. The adjustment plates 14 have a plurality of fixing holes, through which fixing screws 15 extend. One end of the fixing screws 15 is threadedly connected to the outer surface of the protective box 6. The adjustment plates 14, connected to the protective box 6 via the fixing screws 15, are easily disassembled and adjusted.

[0028] The adjustment plate 14 includes two planar plates 16 with fixing holes defined therein. A flexible plate 17 is fixedly connected between the two planar plates 16. Adjusting the angles of the two planar plates 16 can change the overall angle of the adjustment plate 14. The flexible plate 17 serves to connect the two planar plates 16.

[0029] Filling rings 18 are provided between the plurality of rotating shafts 3. Support rings 19 are provided above the uppermost rotating shaft 3 and below the lowermost rotating shaft 3. The outer diameters of the filling rings 18 and support rings 19 are the same as the outer diameters of the rotating shafts 3. The filling rings 18 and support rings 19 can help fix the position of the rotating shafts 3.

[0030] An observation window 13 is provided on the outer surface of the two adjustment grooves 9 . A scale is provided on the observation window 13 , and the scale facilitates observation of the amount of the filling from the outside.

[0031] To install the protective box 6, first install the shaft 3 into the mounting slot 2 of the fixed column, then connect the multiple limit bars 4 to the shaft 3. Install the filler ring 18 between the multiple shafts 3. Then, fit the chute 8 of the protective box 6 onto the corresponding limit bars 4, and the protective box 6 is installed. Finally, install the anti-drop ring 5 at both ends of the limit bars 4 to prevent the protective box 6 from falling off.

[0032] After the installation of the protection box 6 is completed, the sealing cover 10 is opened and a counterweight is installed in the adjustment groove 9. By adjusting the counterweight, part of the protection box 6 floats on the water surface and part of it sinks into the water. When the height of the water level changes, the position of the protection box 6 will also change with the height of the water level under the action of buoyancy, maintaining the protective effect on the fixed column. When the direction of the water flow changes, the protection box 6 will be driven to rotate under the impact of the water flow. The protection box 6 is connected to the fixed column through the rotating shaft 3 and can rotate freely around the fixed column, so that the sharp end of the protection box 6 faces the direction of the water flow, which has the effect of reducing resistance. At the same time, it can guide the debris brought by the water flow, push it away from the fixed pile 1, and protect the fixed pile 1. An adjustment plate 14 is installed on the outside of the protection box 6. By adjusting the angle of the two flat plates 16, the angle of the adjustment plate 14 can be changed to adapt to water flows in different situations.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
