Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and in particular to a cable laying corner device for cable trenches in energy storage stations. Background Technology

[0002] Energy storage stations are key infrastructure in modern energy systems. Their core function is to store electrical energy or other forms of energy and release them when needed. This solves the problem of the mismatch between electricity production and consumption in time and space, and is of great significance for improving grid stability, promoting the consumption of renewable energy, and improving energy efficiency. In the construction of energy storage stations, cables are crucial transmission devices in the power system. Cables are laid in cable trenches within the energy storage area. The trench layout follows the principles of proximity to electrical equipment, shortest paths, and aesthetics. It is a holistic, planned approach, coordinating horizontally and vertically, combining near and far distances, minimizing bends and intersections, and facilitating cable construction, maintenance, and future expansion. Among these considerations, cable laying corner devices are key auxiliary equipment in power engineering construction, a crucial link in ensuring the safety and efficiency of power projects. Existing public documents such as CN118508324B – A cable laying turning device and laying method for corner wells; CN114825179B – A device for manually operated high-voltage cable laying corner pulleys; and CN219498749U – A cable laying corner guide device, all disclose corner devices. While existing cable laying corner devices for energy storage stations can assist in cable cornering, they still have certain shortcomings in practical use. First, most existing cable laying corner devices use corner pulleys, which are designed with a fixed angle and cannot be dynamically adjusted according to the curvature of the bend. Furthermore, their adjustment range and accuracy are severely limited, allowing only planar rotation and lacking support for three-dimensional composite cornering. Second, when the pulleys and contact surfaces of existing cable laying corner devices slide relative to the cable, localized overheating and sheath wear occur, leading to an increased sheath scratch rate. Finally, when cables are laid in cable trenches with large corners, existing cable laying corner devices may fail to provide effective support, causing direct friction between the cable and the trench wall, affecting its lifespan. Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given that most existing cable laying corner devices use corner pulleys, which cannot be dynamically adjusted according to the curvature of the curves on site and lack support for three-dimensional spatial composite corners, a cable laying corner device for cable trenches in energy storage stations is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cable laying corner device for cable trenches in energy storage stations, comprising a corner frame, with a first bracket and a second bracket respectively provided at both ends of the corner frame, both the first bracket and the second bracket being installed on the trench wall by anchor bolts, a guide rod fixed on one side of the inside of the corner frame, and a support plate fixed on one side wall of the corner frame; a quick-release frame, which is installed on the surface of the first bracket and the second bracket, and a rotating groove is provided in the middle of the symmetrical plane inside the quick-release frame; a U-shaped protective frame, the inside of which is installed on the surface of the first bracket and the second bracket by fixing bolts, and the U-shaped protective frame is snapped into the inside of the quick-release frame; and a three-dimensional adjustment component, including... A first handwheel is positioned above the corner bracket, and a first screw is fixed at the center of the bottom of the first handwheel. The bottom end of the first screw passes through a bearing on the corner bracket and connects to a bearing inside the corner bracket. A lifting rod is threaded onto the upper part of the outer wall of the first screw, and a rotating rod is rotatably fitted onto the lower part of the outer wall of the first screw. One end of the outer wall of the rotating rod is rotatably connected to one end of a second screw through a hinge seat. The other end of the second screw passes through a threaded hole on the support plate and connects to the second handwheel. A limiting block is fixed on the outer wall of the first screw, and the limiting block is located between the lifting rod and the rotating rod. One end of the lifting rod is slidably fitted onto the outer wall of the guide rod, and the other ends of the lifting rod and the rotating rod are fixedly connected to the quick-release frame.

[0006] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, the quick-release frame has plate grooves at both ends of the internal symmetrical surface, and movable grooves are opened at the front and rear ends of the bottom of the two side walls of the quick-release frame.

[0007] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, trapezoidal grooves are provided at both ends of the bottom of the two side walls of the U-shaped protective frame, and adjacent U-shaped protective frames are connected by a flexible frame.

[0008] The beneficial effects of this invention are as follows: by setting up a three-dimensional adjustment component, the angle between the rotating rod and the lifting rod can be adjusted, as well as the height difference between the quick-release frames at both ends and the U-shaped protective frame. This allows for precise adjustment of the rotation angle of the two adjustment frames according to the cable trench turning angle, and adjustment of the height between the two adjustment frames according to the cable height direction. This adjusts the angle and height of the cable in three-dimensional space, increasing the applicability.

[0009] Given that existing cable laying corner devices can cause localized overheating and sheath wear when the pulleys and device contact surfaces slide relative to the cable, leading to an increased sheath scratch rate, a further improvement to the cable laying corner device for cable trenches in energy storage stations is proposed.

[0010] As a preferred embodiment of the cable laying corner device for cable trench of energy storage station of the present invention, it further includes a cooling component disposed on the outside of the quick-release frame. The cooling component includes a rotating roller rotatably installed inside the rotating groove and a rotating shaft fixed in the middle of the rotating roller. Hollow grooves are provided at the top and bottom center of the rotating shaft.

[0011] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, a first toothed disc is sleeved on the upper part of the outer wall of the rotating shaft, and an inlet pipe and an outlet pipe are rotatably installed inside the upper and lower hollow grooves respectively; wherein, cooling chambers are evenly spaced along the circumferential direction of the outer wall of the rotating shaft inside the rotating roller, and flow holes are evenly spaced along the circumferential direction of the outer wall of the rotating shaft on the inner wall of the hollow groove, and the flow holes are connected to the cooling chambers.

[0012] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, a coolant tank is provided on the outer side of the rotating roller, a return pipe is provided at the bottom center of the coolant tank, and cooling plates are provided on both sides of the rotating roller; wherein, the cooling plates are installed inside the plate groove, a serpentine tube is provided inside the cooling plates, and the other end of the return pipe is connected to the serpentine tube and the outlet pipe through a pipe joint.

[0013] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, a liquid extraction box is installed on the upper surface of the coolant tank, a liquid extraction pipe is provided at the bottom center of the liquid extraction box, a drain pipe is provided at the top center of the liquid extraction box, and an auxiliary water wheel is rotatably installed at one end of the inside of the liquid extraction box.

[0014] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, a drive water wheel is provided at the other end of the liquid extraction box, a drive shaft is fixed in the middle of the drive water wheel, and one end of the drive shaft passes through the bearing on the liquid extraction box and is connected to the second gear plate; wherein, the bottom end of the liquid extraction pipe extends to the bottom of the coolant tank, the top end of the drain pipe is connected to the other end of the inlet pipe and the serpentine pipe through a pipe joint, and the second gear plate is meshed with the first gear plate.

[0015] Another beneficial effect of the present invention is that by setting up a cooling component, the rotating roller and the cooling plate can be circulated and cooled down, thereby replacing the heat generated by friction during cable laying, reducing the heat of the outer sheath of the cable, ensuring the wear resistance of the cable sheath, and reducing the probability of sheath scratches.

[0016] Given that existing cable laying corner devices sometimes fail to provide effective support when cables are laid in cable trenches with large corners, resulting in direct friction between the cable and the trench wall and affecting its lifespan, a further improvement to the cable laying corner device for cable trenches in energy storage stations is proposed.

[0017] As a preferred embodiment of the cable laying corner device for cable trenches in energy storage stations according to the present invention, it further includes a quick-release assembly disposed on the outer side of the quick-release frame. The quick-release assembly includes a push plate disposed on the outer side of the quick-release frame and a movable plate fixed on the front and rear ends of the outer wall of the push plate. The end of the movable plate is movably connected to the clamping plate through a hinge, and a spring is installed between the clamping plate and the movable plate. The movable plate is slidably mounted on the inner wall of the movable groove.

[0018] Another beneficial effect of the present invention is that by setting up a U-shaped protective frame and a quick-release assembly, the quick-release frame and the U-shaped protective frame can be quickly disassembled and assembled. The U-shaped protective frame can continuously protect the cable, while the flexible frame between the two U-shaped protective frames can prevent the cable from contacting the cable trench wall and causing wear when the cable turns. The subsequent quick-release frame and its structure can be reused, reducing waste. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0037] Example 1 Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 This is the first embodiment of the present invention. This embodiment provides a cable laying corner device for cable trenches in energy storage stations. This cable laying corner device for cable trenches in energy storage stations can adjust the angle and height of the cable in three-dimensional space and has a wide range of applications.

[0038] Specifically, the corner frame 100 has a first bracket 101 and a second bracket 102 at each end, both of which are installed on the trench wall by anchor bolts. A guide rod 103 is fixed to one side of the interior of the corner frame 100, and a support plate 104 is fixed to one side wall of the corner frame 100. A quick-release frame 200 is supported on the surfaces of the first bracket 101 and the second bracket 102, and a rotating groove 201 is provided in the center of each symmetrical surface inside the quick-release frame 200. A U-shaped protective frame 300 is inserted from top to bottom. The quick-release frame 200 is detachably snapped into place by the quick-release assembly 600; the U-shaped protective frame 300 is also mounted on the surface of the first bracket 101 and the second bracket 102 by fixing bolts passing through it, thereby fixing the U-shaped protective frame 300 on the bracket and supporting the quick-release frame 200 between the first bracket 101 or the second bracket 102 and the U-shaped protective frame 300; and the three-dimensional adjustment assembly 400 includes a first handwheel 401 disposed above the corner bracket 100 and a first screw 402 fixed at the center of the bottom of the first handwheel 401.

[0039] For details, please refer to Figure 1 and Figure 7 The bottom end of the first screw 402 passes through the bearing on the corner bracket 100 and is connected to the bearing inside the corner bracket 100. A lifting rod 403 is threadedly sleeved on the upper part of the outer wall of the first screw 402, and a rotating rod 404 is rotatably sleeved on the lower part of the outer wall of the first screw 402. The rotating rod 404 is located below the limiting block 402a and can rotate around the first screw 402. One end of the outer wall of the rotating rod 404 is rotatably connected to one end of the second screw 405 through a hinge seat. The other end of the second screw 405 passes through the threaded hole on the support plate 104 and is connected to the second handwheel 406. The second screw 405 is threadedly engaged with the threaded hole on the support plate 104. When the second handwheel 406 rotates, it drives the second screw 405 to move along its axis and drives the rotating rod 404 to rotate around the first screw 402 through the hinge seat. The ends of the lifting rod 403 and the rotating rod 404 away from the first screw 402 are both fixedly connected to the quick-release frame 200. In use, the above setup involves first attaching the two U-shaped protective frames 300 to the inside of the two quick-release frames 200 using the quick-release assembly 600, thus creating a detachable connection between the U-shaped protective frames 300 and the quick-release frames 200; then, using fixing bolts, attaching the two U-shaped protective frames 300 to the surfaces of the first bracket 101 and the second bracket 102, thereby supporting the quick-release frames 200 and the U-shaped protective frames 300 as a whole on the bracket; finally, placing the cable inside the U-shaped protective frame 300 and guiding it. When laying cables at the corner of a cable trench, first rotate the second handwheel 406. The rotation of the second handwheel 406 will cause the second screw 405 to rotate synchronously. The external thread on the outer wall of the second screw 405 is screw-fitted with the threaded hole on the support plate 104. Therefore, when the second screw 405 rotates, it will move along its axis under the action of the thread, and in conjunction with the hinge seat, it will cause the rotating rod 404 to rotate around the first screw 402 as the center. This allows adjustment of the angle between the rotating rod 404 and the lifting rod 403, and adaptive adjustments based on the angle at the cable trench corner. When laying cables at a corner, if the heights of the cable corner input end and the corner output end are different, rotate the first handwheel 401. The rotation of the first handwheel 401 will cause the first screw... 402 rotates synchronously, and the external thread on the outer wall of the first screw 402 is screwed into the threaded hole on the lifting rod 403. Therefore, when the first screw 402 rotates, it will carry the lifting rod 403 to adjust its height under the action of the guide rod 103. This achieves the purpose of adjusting the height difference between the two ends of the adjustment support unit composed of the quick-release frame 200 and the U-shaped protective frame 300. Thus, it can be used to accurately adjust the angle of the adjustment support unit composed of the quick-release frame 200 and the U-shaped protective frame 300 according to the cable trench angle, and to adjust the height between the two ends of the adjustment support unit composed of the quick-release frame 200 and the U-shaped protective frame 300 according to the cable height direction, thereby adjusting the angle and height of the cable in three-dimensional space and increasing the applicability.

[0040] Furthermore, the first bracket 101 and the second bracket 102 have the same structure and are installed equidistantly on the cable trench wall for supporting cable installation. The guide rod 103 can guide and limit the lifting rod 403, allowing the lifting rod 403 to rise and fall while preventing the lifting rod 403 from rotating. The first screw 402 is only threadedly connected to the lifting rod 403, so when the first screw 402 rotates, it only moves the lifting rod 403 up and down. The limiting block 402a is fixed on the outer wall of the first screw 402, while the rotating rod 404 is rotatably sleeved on the outer wall of the first screw 402. The second screw 405 is engaged with the threaded hole and adjusts the angle of the rotating rod 404 under the action of the hinge seat.

[0041] Read in detail Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the quick-release frame 200 has plate grooves 202 at both ends of the internal symmetrical surface, and the quick-release frame 200 has moving grooves 203 at the front and rear ends of the bottom of both side walls; the U-shaped protective frame 300 has trapezoidal grooves 301 at both ends of the bottom of both side walls, and two adjacent U-shaped protective frames 300 are connected by a flexible frame 302.

[0042] Furthermore, the movable trough 203 has an L-shaped cross-section, and the flexible frame 302 can extend and bend to adjust and bend in accordance with the angle of the cable trench, in order to protect the cable and prevent the cable from contacting and abrading the cable trench wall.

[0043] Example 2 Reference Figure 6 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to reduce the temperature generated by friction during cable laying, the rotating roller 501 and the cooling plate 505 are circulated and cooled to ensure the wear resistance of the cable sheath.

[0044] Specifically, it also includes a cooling assembly 500 disposed on the outside of the quick-release frame 200. The cooling assembly 500 includes a rotating roller 501 rotatably mounted inside the rotating groove 201 and a rotating shaft 502 fixed in the middle of the rotating roller 501. Hollow grooves 502a are provided at the top and bottom centers of the rotating shaft 502. A first toothed disc 502c is sleeved on the upper outer wall of the rotating shaft 502. An inlet pipe 502d and an outlet pipe 502e are rotatably mounted inside the upper and lower hollow grooves 502a, respectively. The rotating roller 501... Cooling chambers 501a are evenly spaced along the circumferential direction of the outer wall of the rotating shaft 502 inside the 01. Flow holes 502b are evenly spaced along the circumferential direction of the outer wall of the rotating shaft 502 on the inner wall of the hollow groove 502a, and the flow holes 502b are connected to the cooling chambers 501a. A coolant tank 504 is provided on the outer side of the rotating roller 501, and a return pipe 504a is provided at the bottom center of the coolant tank 504. Cooling plates 505 are provided on both sides of the rotating roller 501. The cooling plates 505 are installed on... Inside the plate slot 202, a serpentine tube 505a is installed inside the cooling plate 505. The other end of the return pipe 504a is connected to the serpentine tube 505a and the outlet pipe 502e via a pipe connector. A liquid extraction box 503 is installed on the upper surface of the coolant tank 504. A liquid extraction pipe 503a is located at the bottom center of the liquid extraction box 503, and a drain pipe 503b is located at the top center of the liquid extraction box 503. An auxiliary water wheel 503c is rotatably installed at one end inside the liquid extraction box 503. The other end of the interior of 3 is provided with a drive water wheel 503d, and a drive shaft 503e is fixed in the middle of the drive water wheel 503d. One end of the drive shaft 503e passes through the bearing on the liquid extraction box 503 and is connected to the second gear plate 503f. The bottom end of the liquid extraction pipe 503a extends to the bottom of the coolant tank 504, and the top end of the drain pipe 503b is connected to the other end of the inlet pipe 502d and the serpentine pipe 505a through a pipe joint. The second gear plate 503f is meshed with the first gear plate 502c. In use, the cable is placed in the quick-release frame 200 and the U-shaped protective frame 300 at the input end. When guiding the cable at a corner, the cable slides along the inside of the quick-release frame 200 and the U-shaped protective frame 300. As the cable moves, it presses against the inner wall of the U-shaped protective frame 300 towards the inner corner, causing the rotating roller 501 protruding from the center of the U-shaped protective frame 300 to rotate due to friction. The rotation of the rotating roller 501 under force causes the rotating shaft 502 inside it to rotate. The rotation of the rotating shaft 502 causes the first toothed disc 502c on its outer wall to rotate synchronously. The first toothed disc 502c is meshed with the second toothed disc 503f, so the rotation of the first toothed disc 502c causes the second toothed disc 503f to rotate synchronously. The rotation of the second toothed disc 503f is driven by the drive shaft 503e. The water turbine 503d rotates, and in conjunction with the auxiliary water turbine 503c, it draws coolant from the coolant tank 504 through the suction pipe 503a. The coolant then flows through the drain pipe 503b and the inlet pipe 502d into the hollow groove 502a in the serpentine tube 505a and the rotating shaft 502, respectively. The coolant then flows through the flow hole 502b in the hollow groove 502a into the cooling chamber 501a in the rotating roller 501. After flowing in, the coolant returns to the coolant through the outlet pipe 502e and the other end of the serpentine tube 505a via the return pipe 504a. This cools the rotating roller 501 and the cooling plate 505, thereby displacing the heat generated by friction during cable laying, reducing the heat of the outer sheath of the cable, ensuring the wear resistance of the cable sheath, and reducing the probability of sheath scratches.

[0045] Furthermore, the first toothed disc 502c meshes with the second toothed disc 503f to achieve the function of transmission. The inlet pipe 502d and the outlet pipe 502e are rotatably installed in the corresponding hollow groove 502a to prevent the pipes from rotating when the rotating shaft 502 rotates. The cooling chamber 501a in the rotating roller 501 is provided with four chambers and is connected to the hollow groove 502a and the corresponding pipes through the corresponding flow holes 502b. The coolant flowing in the serpentine pipe 505a is used to reduce the temperature of the cooling plate 505. The drive water wheel 503d and the auxiliary water wheel 503c cooperate to draw coolant. The pipe joint realizes the connection of the pipes.

[0046] Example 3 Reference Figure 6 and Figure 13 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to continuously protect the cable at the corner, after the cable is laid, the quick-release frame 200 and the U-shaped protective frame 300 are separated, and the flexible frame 302 is used to avoid the cable from contacting and wearing with the cable trench wall.

[0047] Specifically, it also includes a quick-release assembly 600 disposed on the outer side of the quick-release frame 200. The quick-release assembly 600 includes a push plate 601 disposed on the outer side of the quick-release frame 200 and a movable plate 602 fixed on the front and rear ends of the outer wall of the push plate 601. The end of the movable plate 602 is movably connected to the locking plate 603 via a hinge. A spring 604 is installed between the locking plate 603 and the movable plate 602. The movable plate 602 is slidably mounted on the inner wall of the movable groove 203. In use, after the cable bend is laid, the push plates 601 on both sides are pushed towards the center. The push plates 601, under pressure, move the front and rear moving plates 602 along the inside of the moving groove 203. At this time, since the clamping plate 603 is located in the trapezoidal groove 301 on the U-shaped protective frame 300, the moving plate 602 moves synchronously with the clamping plate 603, causing the clamping plate 603 to slide along the inner wall of the trapezoidal groove 301 and push against the inner wall of the trapezoidal groove 301. This causes the clamping plate 603 to fold towards the moving plate 602 and compress the spring 604. At this point, the clamping plate 603 moves out of the trapezoidal groove 301 and releases the U-shaped protective frame. The protective frame 300 has a limiting effect. The U-shaped protective frame 300 and the quick-release frame 200 are disassembled and separated. Then, the corner bracket 100, quick-release frame 200, etc. are pulled upward to completely separate the corner bracket 100, quick-release frame 200, etc. from the U-shaped protective frame 300. At this time, the two U-shaped protective frames 300 are still installed on the surface of the first bracket 101 and the second bracket 102, and the U-shaped protective frame 300 continuously protects the cable. The flexible frame 302 between the two U-shaped protective frames 300 can also prevent the cable from contacting the cable trench wall and causing wear when the cable turns. The subsequent quick-release frame 200 and its structure can be reused to reduce waste.

[0048] Furthermore, the movable plate 602 is slidably mounted on the inner wall of the movable groove 203, which can ensure the stable movement of the movable plate 602 and has high stability. The clamping plate 603 can rotate under the action of the hinge. Both ends of the spring 604 are provided with limit posts, which can be used to limit the position of the spring 604 and play a guiding role.
