Description

Technical Field

[0001] The present invention relates to the field of power engineering, and more specifically, to a cable fixing device for power engineering. Background Art

[0002] In the field of power engineering, the laying and fixing of submarine cables are the core links to ensure stable power transmission. Therefore, when a submarine cable fails, repair measures must be taken promptly to restore the normal operation of the power system and ensure the reliability and safety of power supply.

[0003] However, submarine cables are vulnerable to natural factors such as water flow impact and tides in the marine environment, resulting in vibrations, so it is necessary to reduce them during inspection and repair;

[0004] In view of the fact that the existing fixing devices can only provide basic cable fixing functions, when the connector of the detection device is connected to the cable during the inspection of submarine cables, the influence of vibrations may cause the joints at the connection part between the connector of the detection device and the cable to become loose or damaged, thereby causing significant errors in the detection results.

[0005] For this reason, a cable fixing device for power engineering is proposed. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a cable fixing device for power engineering, which can reduce the vibration of the cable part to be detected, thereby preventing the joints between the connector of the detection device and the cable joint from becoming loose or damaged.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A cable fixing device for power engineering includes a mounting plate, and a detection device is provided on the mounting plate;

[0009] Fixing mechanisms are evenly arranged on the mounting plate, and the fixing mechanisms are used to fix the cable;

[0010] The fixing mechanism includes two telescopic rods symmetrically and fixedly installed on the bottom wall of the mounting plate. The output ends of the two telescopic rods are close to each other, and the two telescopic rods are on the same straight line. An arc-shaped clamping plate is fixedly installed on the output end of the telescopic rod, and a first insertion rod is fixedly installed on the mounting plate;

[0011] A protective cover is provided outside the mounting plate. The bottom wall of the protective cover is open. An elastic member is jointly installed between the inner wall of the protective cover and the mounting plate. Second insertion rods are evenly and fixedly installed on the bottom wall of the protective cover;

[0012] And a push rod that is vertically slidably inserted on the top wall of the protective cover and cooperates with the mounting plate is provided. A spring is jointly installed between the push rod and the protective cover;

[0013] A clamping mechanism matched with the clamping plate is provided on the mounting plate.

[0014] First, place the mounting plate directly above the cable, and make the part where the cable is connected to the detection device between two adjacent fixing mechanisms, and then make the cable between two clamping plates of the same fixing mechanism;

[0015] Then press the push rod downward, the spring is stretched, and the push rod moves downward and pushes the mounting plate downward; the mounting plate is pushed downward by the push rod, so that the clamping plate moves to the side wall of the cable to be clamped, and at the same time the first plug rod is inserted into the ground, so that the mounting plate can be fixed in this position, and then stop pressing the push rod, at this time the spring drives the push rod to break contact with the mounting plate; at the same time, press the protective cover, and fix the protective cover to the outside of the mounting plate through the second plug rod, so that the water flow cannot directly impact the connection part of the cable and the detection device, reducing the probability of vibration of the connection part and improving the connection stability.

[0016] Under the action of the protective cover, the water flow can be prevented from directly impacting the connection between the cable and the detection device, further reducing the probability of vibration of the connection part, and when the water flow impacts the protective cover, the impact force exerted on the protective cover is absorbed by the elastic part, preventing the impact force from being directly transmitted to the installation plate and the connection between the cable and the detection device, further reducing the probability of looseness of the connection between the cable to be detected and the detection device.

[0017] Then the clamping mechanism works on the surface of the clamping plate, cleaning the surface of the clamping plate and the cable to be clamped, ensuring that the clamping plate can clamp the cable tightly. Therefore, when the rest of the cable vibrates, the probability of vibration at the connection between the cable and the detection device can be reduced.

[0018] Finally, the telescopic rod is started, and the telescopic rod drives the two clamps to approach each other, so that the cable can be clamped by the clamps, and then the mounting plate and the cable are fixed by the first plug rod. At this time, the mounting plate is in a fixed state, and the part to be detected of the cable is clamped by the clamps arranged on the mounting plate, so that the part to be detected can be clamped, reducing the probability of the part to be detected being vibrated by the impact force of the water flow. Therefore, the connector of the detection device can be connected to the cable, and when reducing the vibration of the part to be detected of the cable, the connection between the connector and the cable can be prevented from loosening or being damaged, thereby ensuring the detection accuracy.

[0019] Furthermore, the clamping mechanism includes a cavity formed on the clamping plate, an air hole is formed on the side wall of the cavity away from the telescopic rod, and an air supply mechanism for providing air to the cavity is provided on the protective cover;

[0020] The protective cover is symmetrically provided with wire holes, and the protective cover is provided with a sealing mechanism matched with the wire holes.

[0021] Further, the air supply mechanism includes a gas cylinder fixedly installed inside the protective cover. The gas cylinder contains high-pressure gas, and a conduit extending into the cavity is fixedly installed at the output end of the gas cylinder.

[0022] After the protective cover is fixed to the ground, the part of the wire hole below the cable is blocked by the sealing mechanism, and then the output end of the gas cylinder is opened. At this time, the high-pressure gas in the gas cylinder flows along the conduit, fills the cavity, and is discharged through the air holes on the side wall of the cavity. The gas discharged from the air holes impacts the surface of the cable, and at this time, the impurities attached to the surface of the cable can be washed away, increasing the friction between the clamping plate and the cable, and improving the fixing effect of the clamping plate on the cable; and the air flow gathers in the protective cover with the opening facing down under the action of its own buoyancy. As the air pressure in the protective cover gradually increases, the water in the protective cover gradually drains out through the gap between the bottom wall of the protective cover and the ground, thereby separating the connection part between the cable and the detection device from the water, further reducing the impact of the water flow impact force on the connection part, and improving the stability during the detection process.

[0023] Further, the sealing mechanism includes a semi-circular baffle rotatably installed on the outer side wall of the protective cover, and an adjustment mechanism for driving the baffle to rotate is provided on the protective cover.

[0024] In the initial state, the open end of the baffle faces downward, and at this time, the cable can normally enter the wire hole; after the wire hole is stuck outside the cable, the baffle is driven to rotate by the adjustment mechanism. At this time, the baffle rotates around the cable, and the baffle gradually rotates to the lower part of the cable. At this time, the baffle blocks the part of the wire hole below the cable. Then, when the gas cylinder exhausts gas, the cable can be separated from the water, further reducing the impact force of the water flow on the fixed cable, reducing the probability of cable vibration, and at the same time enabling the water flow discharged from the air holes to directly impact the surface of the cable, improving the cleaning effect on the cable.

[0025] In summary, under the action of the sealing mechanism, it can ensure the stable connection at the joint between the detection device and the cable.

[0026] Further, the adjustment mechanism includes a guiding groove opened on the outer side wall of the protective cover. The guiding groove is semi-circular, and a moving magnet is slidably installed in the guiding groove. The moving magnet is fixedly connected to the end of the outer side wall of the baffle, and a reset magnet and a fixed magnet that attract the moving magnet are respectively embedded at both ends of the guiding groove.

[0027] In the initial state, the baffle is in the state with the open end facing downward. At this time, the moving magnet is attracted to the reset magnet, so that the baffle can be fixed, facilitating the cable to enter the wire hole.

[0028] When it is necessary to adjust the state of the baffle, the staff rotates the baffle. At this time, the baffle makes a circular motion around the center of the cable. During this process, the moving magnet moves along the guiding groove until the opening of the baffle faces upward. At this time, the moving magnet moves to the surface of the fixed magnet, so that the moving magnet can be attracted by the fixed magnet, that is, the baffle is fixed in the state with the opening facing upward, thus playing a role in adjusting the position of the baffle.

[0029] Furthermore, an elastic rope is fixedly installed in the air hole, and a flow disturbing block is fixedly installed on the elastic rope.

[0030] During the exhaust process of the air hole, the airflow impacts the flow disturbing block, and the flow disturbing block shakes, changing the direction of the airflow.

[0031] When the air hole is exposed to the gas environment inside the protective cover, during the shaking process of the flow disturbing block, the contact area between the airflow and the cable is increased, improving the cleaning effect on the cable.

[0032] After the gas cylinder completes the exhaust, the elastic rope resumes its original state and drives the flow disturbing block to move into the air hole, playing a role in ensuring that the clamping plate can directly contact the cable.

[0033] Furthermore, the flow disturbing block is made of rubber, and friction lines are provided on the outer wall of the flow disturbing block.

[0034] As the liquid level drops, the flow disturbing block is gradually exposed to the gas environment inside the protective cover. At this time, the resistance received by the flow disturbing block is small, so the flow disturbing block will contact the cable, and under the action of the airflow impact force, the flow disturbing block slides on the surface of the cable. At this time, the friction lines rub on the surface of the cable, thereby improving the cleaning effect on the surface of the cable.

[0035] Furthermore, a buffer pad is fixedly installed on the side wall of the baffle away from the protective cover. The buffer pad is semi-circular ring-shaped, and the ratio of the inner diameter of the baffle to the inner diameter of the buffer pad is 1.1 - 1.2.

[0036] When the cable is installed in the wire hole, the side wall of the buffer pad is closely attached to the outer wall of the cable. When the cable outside the protective cover that is not fixed vibrates, it can drive the buffer pad to deform. At this time, the buffer pad absorbs the kinetic energy of the cable, thereby reducing the probability of vibration of the cable fixed by the fixing mechanism.

[0037] Furthermore, a cavity is provided on the buffer pad, and a pressure pipe extending into the protective cover is inserted on the side wall of the cavity.

[0038] Therefore, when the air pressure inside the protective cover increases, the high-pressure gas flows along the pressure pipe into the cavity. At this time, the air pressure inside the cavity increases, and the buffer pad made of elastic material expands, thereby increasing the contact area between the buffer pad and the cable. According to the pressure formula, when the contact area increases, with the pressure remaining unchanged, the pressure will decrease. This means that the pressure acting on the unit area decreases, thereby reducing the impact force on the buffer pad, further reducing the vibration degree of the cable, and improving the absorption effect of the buffer pad on the kinetic energy of the cable.

[0039] Furthermore, the pressure pipe is made of elastic material, thus ensuring the normal rotation of the baffle.

[0040] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0041] (1) Through the mutual cooperation of the fixing mechanism, protective cover, elastic member, and push rod, this solution can fix one end of the cable to be detected through the fixing mechanism. Therefore, when the detection device is connected to the cable, the vibration degree of the connection part between the cable and the detection device can be reduced, the probability of loosening or damage of the connection part is reduced, and at the same time, the protective cover can prevent water flow from directly impacting the connection part of the cable and the detection device, thereby reducing the vibration probability of the connection part and improving the connection stability.

[0042] (2) Through the mutual cooperation of the cavity, air holes, and gas cylinder, the high-pressure gas in the gas cylinder flows along the conduit to fill the cavity and is discharged through the air holes on the side wall of the cavity. The gas discharged from the air holes impacts the surface of the cable. At this time, the impurities attached to the surface of the cable can be cleaned, increasing the friction between the clamping plate and the cable, and improving the fixing effect of the clamping plate on the cable; and the air flow gathers in the protective cover with a downward opening under the action of its own buoyancy. As the air pressure in the protective cover gradually increases, the water in the protective cover gradually drains through the gap between the bottom wall of the protective cover and the ground, thereby separating the connection part of the cable and the detection device from contact with water, further reducing the impact of the water flow impact force on the connection part, and improving the stability during the detection process.

[0043] (3) Through the mutual cooperation of the baffle, fixed magnet, and moving magnet, the baffle rotates around the cable, and the baffle gradually rotates to the lower part of the cable. At this time, the baffle blocks the part of the wire hole below the cable, so that when the gas cylinder exhausts, the cable can be separated from contact with water, further reducing the impact force of the water flow on the fixed cable, reducing the probability of cable vibration, and at the same time enabling the water flow discharged from the air holes to directly impact the surface of the cable, improving the cleaning effect on the cable.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Embodiment 1:

[0054] Please refer to Figures 1 to 6 , a cable fixing device for power engineering, including a mounting plate 1, and a detection device 2 is provided on the mounting plate 1;

[0055] Fixing mechanisms are uniformly provided on the mounting plate 1, and the fixing mechanisms are used to fix the cable;

[0056] The fixing mechanism includes two telescopic rods 3 symmetrically and fixedly installed on the bottom wall of the mounting plate 1. The output ends of the two telescopic rods 3 are close to each other, and the two telescopic rods 3 are on the same straight line. An arc-shaped clamping plate 4 is fixedly installed on the output end of the telescopic rod 3, and a first plug rod 5 is fixedly installed on the mounting plate 1;

[0057] The outer cover of the mounting plate 1 is provided with a protective cover 6, the bottom wall of the protective cover 6 is open, an elastic member 7 is installed between the inner wall of the protective cover 6 and the mounting plate 1, and a second plug rod 8 is evenly fixedly installed on the bottom wall of the protective cover 6;

[0058] A push rod 9 that cooperates with the mounting plate 1 is vertically slidably inserted on the top wall of the protective cover 6, and a spring 10 is installed between the push rod 9 and the protective cover 6;

[0059] A clamping mechanism cooperating with the clamping plate 4 is provided on the mounting plate 1 .

[0060] First, place the mounting plate 1 directly above the cable, and make the portion where the cable is connected to the detection device 2 between two adjacent fixing mechanisms, and then make the cable between two clamping plates 4 of the same fixing mechanism;

[0061] Then press the push rod 9 downward, at this time the spring 10 is stretched, and the push rod 9 moves downward and pushes the mounting plate 1 downward; the mounting plate 1 is pushed downward by the push rod 9, so that the clamping plate 4 moves to the side wall of the cable to be clamped, and at the same time the first plug rod 5 is inserted into the ground, so that the mounting plate 1 can be fixed in this position, and then stop pressing the push rod 9, at this time the spring 10 drives the push rod 9 to break contact with the mounting plate 1; at the same time, press the protective cover 6, and fix the protective cover 6 to the outside of the mounting plate 1 through the second plug rod 8, so that the water flow cannot directly impact the connection part between the cable and the detection device 2, thereby reducing the probability of vibration of the connection part and improving the connection stability.

[0062] Under the action of the protective cover 6, the water flow can be prevented from directly impacting the connection between the cable and the detection device 2, further reducing the probability of vibration of the connection part, and when the water flow impacts the protective cover 6, the impact force exerted on the protective cover 6 is absorbed by the elastic member 7, preventing the impact force from being directly transmitted to the connection between the mounting plate 1 and the cable and the detection device 2, further reducing the probability of looseness of the connection between the cable to be detected and the detection device 2.

[0063] Then the clamping mechanism works on the surface of the clamping plate 4, and cleans the surface of the clamping plate 4 and the part of the cable to be clamped, ensuring that the clamping plate 4 can clamp the cable tightly. Therefore, when the rest of the cable vibrates, the probability of vibration at the connection part between the cable and the detection device 2 can be reduced.

[0064] Finally, the telescopic rod 3 is activated. The telescopic rod 3 drives the two clamping plates 4 to approach each other, so that the cable can be clamped by the clamping plates 4. Then, the mounting plate 1 is fixed to the cable through the first insertion rod 5. At this time, the mounting plate 1 is in a fixed state, and the part of the cable to be detected is clamped by the clamping plates 4 provided on the mounting plate 1. Furthermore, the part to be detected can be clamped, reducing the probability of vibration of the part to be detected due to the impact of water flow. Therefore, the connector of the detection device 2 can be connected to the cable, and when the vibration of the part of the cable to be detected is reduced, the loosening or damage of the connection between the connector and the cable can be prevented, thus ensuring the detection accuracy.

[0065] As Figure 4 shown, the clamping mechanism includes a cavity 11 formed in the clamping plate 4. An air hole is formed in the side wall of the cavity 11 away from the telescopic rod 3, and a gas supply mechanism for supplying gas to the cavity 11 is provided on the protective cover 6.

[0066] Symmetrically arranged wire holes 12 are formed in the protective cover 6, and a sealing mechanism cooperating with the wire holes 12 is provided on the protective cover 6.

[0067] As Figure 3 shown, the gas supply mechanism includes a gas cylinder 13 fixedly installed in the protective cover 6. High-pressure gas is contained in the gas cylinder 13. A conduit 14 extending into the cavity 11 is fixedly installed at the output end of the gas cylinder 13, and the conduit 14 is a flexible hose.

[0068] After the protective cover 6 is fixed to the ground, the part of the wire hole 12 located below the cable is blocked by the sealing mechanism. Then, the output end of the gas cylinder 13 is opened. At this time, the high-pressure gas in the gas cylinder 13 flows along the conduit 14, fills the cavity 11 and is discharged through the air holes in the side wall of the cavity 11. The gas discharged from the air holes impacts the surface of the cable. At this time, the impurities attached to the surface of the cable can be washed away, increasing the friction between the clamping plate 4 and the cable and improving the fixing effect of the clamping plate 4 on the cable. And the airflow gathers in the protective cover 6 with the opening downward under the action of its own buoyancy. As the air pressure in the protective cover 6 gradually increases, the water in the protective cover 6 gradually drains out through the gap between the bottom wall of the protective cover 6 and the ground, further separating the connection part between the cable and the detection device 2 from the water contact, and further reducing the influence of the water flow impact force on the connection part and improving the stability during the detection process.

[0069] As Figure 3 shown, the sealing mechanism includes a semi-circular baffle 15 rotatably installed on the outer side wall of the protective cover 6, and an adjustment mechanism for driving the baffle 15 to rotate is provided on the protective cover 6.

[0070] In the initial state, the open end of the baffle 15 faces downward, and at this time, the cable can enter the wire hole 12 normally; after the wire hole 12 is stuck outside the cable, the baffle 15 is driven to rotate by the adjustment mechanism. At this time, the baffle 15 rotates around the cable, and the baffle 15 gradually rotates to the lower part of the cable. At this time, the baffle 15 blocks the part of the wire hole 12 below the cable. Thus, when the gas cylinder 13 exhausts gas, the cable can be separated from the water, further reducing the impact force of the water flow on the fixed cable, reducing the probability of cable vibration, and at the same time enabling the water flow discharged from the air hole to directly impact the surface of the cable, improving the cleaning effect on the cable.

[0071] In summary, under the action of the sealing mechanism, it can ensure the stable connection between the detection device 2 and the cable.

[0072] As Figure 6 shown, the adjustment mechanism includes a guiding groove 16 opened on the outer side wall of the protective cover 6. The guiding groove 16 is semi-circular ring-shaped. A moving magnet 17 is slidably installed in the guiding groove 16. The moving magnet 17 is fixedly connected to the end of the outer side wall of the baffle 15. And reset magnets 18 and fixed magnets 19 that attract the moving magnet 17 are respectively embedded at both ends of the guiding groove 16.

[0073] In the initial state, the baffle 15 is in the state with the opening facing downward. At this time, the moving magnet 17 is attracted by the reset magnet 18, so that the baffle 15 can be fixed, facilitating the cable to enter the wire hole 12.

[0074] When the state of the baffle 15 needs to be adjusted, the staff rotates the baffle 15. At this time, the baffle 15 makes a circular motion around the center of the cable. During this process, the moving magnet 17 moves along the guiding groove 16 until the opening of the baffle 15 faces upward. At this time, the moving magnet 17 moves to the surface of the fixed magnet 19, so that the moving magnet 17 can be attracted by the fixed magnet 19, that is, the baffle 15 is fixed in the state with the opening facing upward. Therefore, it plays a role in adjusting the position of the baffle 15.

[0075] As Figure 4 shown, an elastic rope 20 is fixedly installed in the air hole, and a flow disturbance block 21 is fixedly installed on the elastic rope 20.

[0076] During the exhaust process of the air hole, the airflow impacts the flow disturbance block 21, and the flow disturbance block 21 shakes, changing the airflow direction.

[0077] When the air hole is exposed to the gas environment inside the protective cover 6, during the shaking process of the flow disturbance block 21, the contact area between the airflow and the cable is increased, improving the cleaning effect on the cable.

[0078] After the gas cylinder 13 finishes exhausting gas, the elastic rope 20 restores and drives the flow disturbance block 21 to move into the air hole, playing a role in ensuring that the clamping plate 4 can directly contact the cable.

[0079] As shown Figure 4 in the figure, the spoiler block 21 is made of rubber, and friction lines are provided on the outer wall of the spoiler block 21.

[0080] As the liquid level drops, the spoiler block 21 is gradually exposed to the gas environment inside the protective cover 6. At this time, the resistance received by the spoiler block 21 is small. Therefore, the spoiler block 21 will come into contact with the cable, and under the action of the air flow impact force, the spoiler block 21 slides on the surface of the cable. At this time, the friction lines rub on the surface of the cable, thereby improving the cleaning effect on the surface of the cable.

[0081] As shown Figure 3 in the figure, a buffer pad 22 is fixedly installed on the side wall of the baffle 15 away from the protective cover 6. The buffer pad 22 is semi-circular ring-shaped, and the ratio of the inner diameter of the baffle 15 to the inner diameter of the buffer pad 22 is 1.1 - 1.2.

[0082] When the cable is installed in the wire hole 12, the side wall of the buffer pad 22 is closely attached to the outer wall of the cable. When the cable outside the protective cover 6 that is not fixed vibrates, it can drive the buffer pad 22 to deform. At this time, the buffer pad 22 absorbs the kinetic energy of the cable, thereby reducing the probability of the cable fixed by the fixing mechanism from vibrating.

[0083] As shown Figure 5 in the figure, a cavity 23 is provided on the buffer pad 22, and a pressure pipe 24 extending into the protective cover 6 is inserted on the side wall of the cavity 23.

[0084] Therefore, when the air pressure inside the protective cover 6 increases, the high-pressure gas flows along the pressure pipe 24 into the cavity 23. At this time, the air pressure in the cavity 23 increases, and the buffer pad 22 made of elastic material expands, thereby increasing the contact area between the buffer pad 22 and the cable. According to the pressure formula, when the contact area increases, with the pressure remaining unchanged, the pressure will decrease. This means that the pressure acting on the unit area decreases, thereby reducing the impact force on the buffer pad 22, further reducing the vibration degree of the cable, and improving the absorption effect of the buffer pad 22 on the kinetic energy of the cable.

[0085] As shown Figure 6 in the figure, the pressure pipe 24 is made of elastic material, thus playing a role in ensuring that the baffle 15 can rotate normally.

[0086] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
