Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, and in particular to an anti-scouring device for a wind power generation cable. Background Art

[0002] Wind power generation is an important renewable energy technology that can effectively reduce greenhouse gas emissions and provide clean electricity for modern society.

[0003] Cable protection is particularly important in wind power generation systems. Cables are laid between wind turbines and connected to the power grid through cables. By utilizing the abundant wind resources at the seaside, the wind power generation system can be used to efficiently generate wind power. At the same time, the erosion of water flow can cause damage to the cables. It is crucial to protect the cables and reduce the operating risks. They need to effectively resist erosion and other environmental influences.

[0004] Most existing cable laying methods use a method of burying cables in mud and sand, but the mud and sand will still be washed away during the flushing process of water flow, exposing the cables to the outside, causing the problem of cable scouring damage. Therefore, a wind power cable anti-scouring device is introduced. Summary of the invention

[0005] The object of the present invention is to provide a wind power cable anti-scouring device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A wind power cable anti-scour device comprises a cable body and a silt layer, a protective mechanism is installed on the outer wall of the cable body, the protective mechanism and the cable body are buried in the silt layer together, a top plate is arranged on the top of the protective mechanism, the top plate covers the surface of the silt layer, and a sand discharge mechanism is arranged on the top of the top plate;

[0008] The protection mechanism includes a column, one end of the column is connected to a clamping sleeve, one side of the clamping sleeve is hinged with a splint, the top of the splint is fixedly connected to a rotating plate, the top of the clamping sleeve is laterally provided with a clamping block through an extended plate, one side of the rotating plate is clamped with the clamping block, and the bottom end of the column is installed with a base foot.

[0009] The clamp is configured to be arc-shaped, and the clamp is fitted with the outer wall of the cable body through the arc-shaped inner wall. There are four clamps, and the four clamps are arranged in a rectangular array with respect to the bottom of the top plate. An arc-shaped slide groove is provided on one side of the clamp close to the column. The column, the clamping sleeve, the clamp, the rotating plate and the clamping block constitute a quick clamping structure. The width of the arc-shaped slide groove is equal to the width of the clamping block. The arc-shaped slide groove is formed by taking the hinge point on one side of the clamp as the center and the distance between the hinge point and the clamping block as the radius. The clamp is staggered on one side of the column so that the bottom end of the clamp can be rotated upward through the hinge point. A spring telescopic structure is provided inside the clamping block. The spring telescopic structure is composed of a groove and a spring. One end of the spring is arranged at the bottom of the groove, and the other end of the spring is connected to the clamping block. The groove is horizontally provided on an extension plate on one side of the clamping sleeve with respect to the clamping block. The clamping block is pressed to shrink to the inner wall of the groove, and the inner wall of the clamp is not in contact with the cable. The main body can be deflected when it is clamped. When the cable body is clamped and fixed, the clamp naturally droops, and the top of the clamp is clamped with the clamp block through the rotating plate. When the protective mechanism is clamped on the cable body, the quick clamping structure is vertically lowered onto the cable body, and the bottom of the clamp contacts the cable body, pushing the clamp to deflect, pressing the clamp block to shrink and disengage from the clamping of the rotating plate, allowing the clamp to deflect freely, and clamp the cable body after the clamp has deflected one circle, and the clamp block is released to return to its original position, so that the clamp block is clamped with the rotating plate. The clamp plate quickly clamps the cable body, fixes the relative position of the protective mechanism and the cable body, and improves the installation efficiency of the staff.

[0010] The foot at the bottom of the column is set as a conical structure, and there are four of the foot. The foot in the protection mechanism is buried and installed along with the cable body. When the cable body is buried in the mud and sand layer, the foot is driven to be inserted into the mud and sand layer at the same time, and the conical structure of the foot is used to quickly insert the foot into the mud and sand layer. A plurality of anti-scour devices are installed on the cable body, and the plurality of anti-scour devices are equidistantly arranged on the cable body, so that the plurality of foot is inserted into the mud and sand layer, fixes the lateral position of the entire cable body, and improves the stability of the cable body.

[0011] The top plate includes a cover plate, the bottom of which is fitted with the upper surface of the silt layer, a clamping rod is provided at the bottom of the cover plate, a pressing plate is fixedly connected to the bottom end of the clamping rod, and the pressing plate is clamped with the cable body. The pressing plate is used to fix the cable body in cooperation with the clamping plate. At the cross section of the cable body, the bottom of the cable body is supported by two symmetrically arranged clamping plates to limit the sinking and lateral displacement of the cable body. The top of the cable body is resisted downward by the clamping plate to limit the floating and longitudinal displacement of the cable body, further stabilizing the stability of the cable body installation and enhancing the stable connection between the anti-scouring device and the cable body.

[0012] The upper surface of the cover plate is provided with an indicator light, and the bottom of the indicator light is provided with a conductive iron sheet through a wire, and the conductive iron sheet is connected to the clamp. The staff can quickly check by observing the indicator light on the top of the cover plate. When the cable body is damaged, the problem is first found through the change in the power voltage value between the wind turbines, and then the cable body buried between the wind turbines is checked. After the cable body is damaged, leakage occurs, and the current is transmitted to the conductive patch through the damaged part of the cable body. The conductive patch works on the indicator light to light up, indicating that there is a leakage problem. The conductive property of the water body is utilized, and multiple anti-scouring devices are equidistantly arranged on the cable body at the same time. Multiple indicator lights will light up at the leakage point. Due to the resistance characteristics of the water body, the farther away from the leakage point, the darker the brightness of the indicator light, and vice versa, the brighter the brightness of the indicator light, which is convenient for the staff to quickly determine and repair the location of the damage.

[0013] The sand discharge mechanism includes a movable rotating sleeve, the inner wall of the movable rotating sleeve is movably connected to the top of the column, one side of the movable rotating sleeve is connected to a hinge, a corrugated plate is provided on the side of the hinge away from the movable rotating sleeve, the upper surface of the cover plate is set as an arc surface, the cross-section of the corrugated plate is set as a wave shape, fins are provided on both sides of the corrugated plate, and the fins are used to stabilize the swinging direction of the corrugated plate. After the cable body and the protective mechanism are buried in the mud layer, the upper surface of the cover plate is set to an arc surface, and the water flows along the arc-shaped cover plate surface, generating a downward pressure on the bottom of the cover plate to stabilize the relative position between the cover plate and the mud layer. At the same time, when the water flows along the arc-shaped surface on the cover plate, the water flows and scours the corrugated plate. The cross-section of the corrugated plate is set to a wave shape. With the push of the water flow, the force direction of the bottom of the corrugated plate is constantly changing, and one side of the corrugated plate is constantly deflected around the hinge, so that the corrugated plate swings upward under the scouring of the water flow. The corrugated plate deflects downward under the action of gravity, so that the corrugated plate continuously swings up and down under the action of the water flow. When the corrugated plate deflects downward, it pushes the water flow to flow toward the surface of the cover plate, changes the scouring angle of the water flow on the mud on the surface of the cover plate, forms a water flow disturbance on the surface of the cover plate, and reduces the accumulation of mud on the surface of the cover plate.

[0014] A hook is provided on the top of the cover plate, and the hook is movably connected to the cover plate. When the cable body needs to be repaired, the damaged position is determined by the indicator light, and then the anti-scouring device near the damaged position is lifted by the lifting device on the hooks provided on both sides of the damaged position of the cable body, so that the cable body is evenly stressed, and the secondary damage to the damaged position on the cable body during the lifting process is reduced. At the same time, the height of the cable body is raised, and the impact of mud and sand on the cable body is reduced. At the same time, the high-intensity work of maintenance personnel in the deep-water high-pressure environment is reduced, the harm of the high-pressure environment to maintenance personnel is reduced, and the efficiency of cable body maintenance and repair is improved.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] The wind power cable anti-scour device of the present invention provides a protection mechanism to quickly wrap and clamp the outer wall of the cable body, thereby improving the efficiency of cable installation and burial. After the protection mechanism and the cable body are clamped, they are buried in the mud layer, and the clamping plate is used to reduce the damage of the cable body caused by the pressure inside the mud. The top plate is used to protect the top of the cable body to reduce the threat of external impact to the cable. The arc structure on the top of the cover plate is used to generate downward pressure when water flows on its surface, thereby stabilizing the position of the cable body. In conjunction with the corrugated plate in the sand discharge mechanism, the water flow pushes the corrugated plate to swing, and pushes the water flow to flow toward the upper surface of the cover plate to flush the mud on the upper surface of the cover plate, thereby ensuring the cleanliness of the cover plate surface and preventing the accumulation of mud and sand from burying the entire device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 , the present invention provides a technical solution:

[0030] A wind power cable anti-scour device comprises a cable body 1 and a silt layer 5, a protective mechanism 2 is installed on the outer wall of the cable body 1, the protective mechanism 2 and the cable body 1 are buried together in the silt layer 5, a top plate 3 is arranged on the top of the protective mechanism 2, the top plate 3 covers the surface of the silt layer 5, and a sand discharge mechanism 4 is arranged on the top of the top plate 3;

[0031] The protection mechanism 2 includes a column 201, one end of the column 201 is connected to a clamping sleeve 202, one side of the clamping sleeve 202 is hinged with a splint 203, the top of the splint 203 is fixedly connected to a rotating plate 204, the top of the clamping sleeve 202 is laterally provided with a clamping block 205 through an extended plate, one side of the rotating plate 204 is clamped with the clamping block 205, and the bottom end of the column 201 is installed with a base foot 206.

[0032] The clamping plate 203 is arranged in an arc shape, and the clamping plate 203 is fitted with the outer wall of the cable body 1 through the arc inner wall. There are four clamping plates 203, and the four clamping plates 203 are arranged in a rectangular array at the bottom of the top plate 3. An arc-shaped sliding groove is opened on one side of the clamping plate 203 close to the column 201. The column 201, the sleeve 202, the splint 203, the rotating plate 204 and the block 205 constitute a quick clamping structure. The width of the arc-shaped slide groove is equal to the width of the block 205. The arc-shaped slide groove takes the hinge point on one side of the splint 203 as the center and the distance from the hinge point to the block 205 as the radius. The splint 203 is staggered on one side of the column 201 so that the bottom end of the splint 203 can rotate upward through the hinge point. The block 205 is provided with a spring telescopic structure inside. The spring telescopic structure is composed of a groove and a spring. One end of the spring is arranged at the bottom of the groove, and the other end of the spring is connected to the block 205.

The block 205 is pressed to shrink to the inner wall of the groove, and the splint 203 When the inner wall is not engaged with the cable body 1, it can be deflected. When the cable body 1 is clamped and fixed, the clamp 203 naturally droops, and the top of the clamp 203 is engaged with the clamp block 205 through the rotating plate 204. When the protective mechanism 2 is clamped to the cable body 1, the quick clamping structure is vertically lowered to the cable body 1, and the bottom of the clamp 203 contacts the cable body 1, pushing the clamp 203 to deflect, pressing the clamp block 205 to retract and disengage from the engagement with the rotating plate 204, so that the clamp 203 can deflect freely. After the clamp 203 deflects one circle, the cable body 1 is clamped, and the clamp block 205 is released to return to its original position, so that the clamp block 205 is engaged with the rotating plate 204. The clamp 203 quickly clamps the cable body 1 to fix the relative position of the protective mechanism 2 and the cable body 1.

[0033] The foot 206 at the bottom of the column 201 is configured as a conical structure, and four foots 206 are provided.

[0034] In one embodiment, the base foot 206 in the protection mechanism is buried and installed along with the cable body 1. When the cable body 1 is buried in the mud layer 5, the base foot 206 is simultaneously driven to be inserted into the mud layer 5. The base foot 206 is quickly inserted into the mud layer 5 through the conical structure of the base foot 206. A plurality of anti-scour devices are installed on the cable body 1. The plurality of anti-scour devices are equidistantly arranged on the cable body 1, so that a plurality of base feet 206 are inserted into the mud layer 5, thereby fixing the lateral position of the entire cable body 1 and improving the stability of the cable body 1.

[0035] The top plate 3 includes a cover plate 301, the bottom of which is fitted with the upper surface of the silt layer 5, a clamping rod 302 is provided at the bottom of the cover plate 301, a pressing plate 303 is fixedly connected to the bottom end of the clamping rod 302, and the pressing plate 303 is clamped with the cable body 1. The pressing plate 303 also cooperates with the clamping plate 203 to fix the cable body 1. At the cross section of the cable body 1, the bottom of the cable body 1 is supported by two symmetrically arranged clamping plates 203 to limit the sinking and lateral displacement of the cable body 1, and the top of the cable body 1 is resisted downward by the clamping plate 303 to limit the floating and longitudinal displacement of the cable body 1, further stabilizing the stability of the installation of the cable body 1, and enhancing the stable connection between the anti-scouring device and the cable body 1.

[0036] An indicator light 304 is disposed on the upper surface of the cover plate 301 , and a conductive iron sheet is disposed at the bottom of the indicator light 304 via a wire, and the conductive iron sheet is connected to the clamping plate 203 .

[0037] In one embodiment, the staff conducts a quick inspection by observing the indicator light 304 on the top of the cover 301. When the cable body 1 is damaged, the problem is first discovered through the change in the power voltage value between the wind turbines. The cable body 1 buried between the wind turbines is then checked. After the cable body 1 is damaged, leakage occurs. The current is transmitted to the conductive patch through the damaged part of the cable body 1. The conductive patch works on the indicator light 304 to light up, indicating that there is a leakage problem. By utilizing the conductive property of the water body, multiple anti-scouring devices are equidistantly arranged on the cable body 1, and multiple indicator lights 304 are lit at the leakage point. Due to the resistance characteristics of the water body, the farther away from the leakage point, the dimmer the brightness of the indicator light 304, and vice versa, the brighter the brightness of the indicator light 304, which is convenient for the staff to quickly determine and repair the location of the damage.

[0038] A hook 305 is provided on the top of the cover plate 301 , and the hook 305 is movably connected to the cover plate 301 .

[0039] In one embodiment, when the cable body 1 needs to be repaired, the damaged position is determined by the indicator light 304, and then the anti-scour device near the damaged position is hoisted by the hoisting device to the hooks 305 provided on both sides of the damaged position of the cable body 1, so that the cable body 1 is evenly stressed, thereby reducing secondary damage to the damaged position on the cable body 1 during the lifting process, and at the same time raising the height of the cable body 1 to reduce the impact of mud and sand on the cable body 1. At the same time, it reduces the high-intensity work of maintenance personnel in the deep-water high-pressure environment, reduces the harm of the high-pressure environment to maintenance personnel, and improves the efficiency of maintenance and repair of the cable body 1.

[0040] The bottom of the hook 305 passes through the cover plate 301 and is connected to the clamping rod 302. The top of the clamping rod 302 is connected to the bottom of the hook 305 through a telescopic sleeve structure. The telescopic sleeve is provided with an outer sleeve and an inner sleeve. The outer sleeve is clamped on the outer wall of the inner sleeve. The outer sleeve is connected to the bottom of the cover plate 301 to form a waterproof structure. The inner sleeve is connected to the bottom thread of the hook 305 through the thread of the inner wall. The pressing plate 303 is set to an arc shape. Through the clamping of the arc-shaped pressing plate 303 and the outer wall of the cable body 1, the hook 305 is rotated along the inner wall of the inner sleeve. The bottom of the clamping rod 302 is restricted by the pressing plate 303 to rotate, and the extension length of the clamping rod 302 is adjusted.

[0041] In one embodiment, when the protective mechanism 2 needs to be removed from the cable body 1, the hook 305 is hung by the lifting device, and then the hook 305 is rotated so that the bottom end of the hook 305 rotates along the top of the clamping rod 302, shrinking the length of the clamping rod 302, and synchronously driving the pressure plate 303 to rise, disengaging the contact and clamping connection between the pressure plate 303 and the cable body 1, and then the top plate 3 is lowered vertically as a whole, so that the clamping plate 203 is disengaged from the clamping connection with the cable body 1, and the rotating plate 204 on the top of the clamping plate 203 is deflected, and the rotating plate 204 is deflected toward the side away from the clamping block 205. After the rotating plate 204 is deflected one hundred and eighty degrees, the obstruction of the contact clamping plate 203 to the cable body 1 is quickly released, and the clamping of the cable body 1 is quickly released, which is convenient for the staff to quickly remove the protective mechanism 2, and convenient for the user to disassemble and assemble, thereby improving the working efficiency of the device.

[0042] The sand discharge mechanism 4 includes a movable sleeve 401, the inner wall of which is movably connected to the top of the column 201, a hinge 402 is connected to one side of the movable sleeve 401, and a corrugated plate 403 is provided on the side of the hinge 402 away from the movable sleeve 401. The upper surface of the cover plate 301 is set as an arc surface, the cross section of the corrugated plate 403 is set as a wave shape, and fins are provided on both sides of the corrugated plate 403, and the fins are used to stabilize the swing direction of the corrugated plate 403.

[0043] In one embodiment, after the cable body 1 and the protection mechanism 2 are buried in the silt layer 5, the upper surface of the cover plate 301 is set to an arc surface, and the water flows along the arc-shaped surface of the cover plate 301, generating a downward pressure on the bottom of the cover plate 301, thereby stabilizing the relative position between the cover plate 301 and the silt layer 5. At the same time, when the water flows along the arc-shaped surface on the cover plate 301, the water scours the corrugated plate 403, and the cross-section of the corrugated plate 403 is set to be wavy. With the push of the water flow, the force direction of the bottom of the corrugated plate 403 is constantly changed, and one side of the corrugated plate 403 is around the hinge 40 2 continuously deflects, so that the corrugated plate 403 swings upward under the scouring of the water flow, and the corrugated plate 403 deflects downward under the action of gravity, so that the corrugated plate 403 continuously swings up and down under the action of the water flow. When the corrugated plate 403 deflects downward, it pushes the water flow to flow toward the surface of the cover plate 301, changes the scouring angle of the water flow on the sediment on the surface of the cover plate 301, forms water flow disturbance on the surface of the cover plate 301, reduces the accumulation of sediment on the surface of the cover plate 301, improves the cleanliness of the surface of the cover plate 301, and is convenient for the staff to observe the indicator light 304 on the surface of the cover plate 301 in real time;

[0044] By the continuous swinging of the corrugated plate 403 on the surface of the cover plate 301, the device as a whole forms a bionic structure, which facilitates the rapid recovery of the underwater natural environment and reduces the damage to the natural environment caused by the buried installation of the cable body 1;

[0045] At the same time, the corrugated plate 403 is continuously swung on the bottom of the water to disturb the water flow, thereby preventing the attachment and growth of aquatic organisms, reducing the covering effect of aquatic organisms on the cover plate 301, and reducing the harm of aquatic organism attachment to the cable body 1.

[0046] In one embodiment, after the protection mechanism 2 is clamped onto the cable body 1, the device for lowering the cable body 1 hoists the hook 305 on the top of the cover plate 301, and the cable body 1 is lowered into the water. The disc structure of the cover plate 301 and the corrugated plate 403 on the top of the cover plate 301 assist in lowering the cable body 1, thereby reducing the working pressure of the lifting device. The cover plate 301 and the corrugated plate 403 buffer the sinking of the cable body 1. At the same time, the corrugated plate 403 is used to guide the sinking direction of the cable body 1. The corrugated plate 403 follows the vertical sinking direction of the cable body 1. The corrugated plate 403 is deflected to the vertical direction by the hinge 402. The fins arranged on both sides of the corrugated plate 403 stabilize the direction of the cable body 1, thereby reducing the influence of water flow on the lowering installation of the cable body 1 and avoiding the problem of installation misalignment.
