Description

Technical Field

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

[0002] In the field of power engineering, the laying and securing of submarine cables is a key step in ensuring stable power transmission. Therefore, when a submarine cable fails, rapid repairs are essential to restore the normal operation of the power system and ensure the reliability and safety of power supply.

[0003] However, submarine cables are susceptible to natural factors such as water current impact and tides in the marine environment, which can cause vibrations and therefore need to be reduced during inspection and maintenance;

[0004] Given that existing fixing devices can only provide basic cable fixing functions, when conducting submarine cable inspections, the impact of vibration when the connector of the inspection equipment is connected to the cable may cause the joints at the connection point between the connector of the inspection equipment and the cable to loosen or be damaged, thereby causing significant errors in the inspection results.

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

[0006] In response to 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 tested, thereby preventing loosening or damage between the connector of the testing equipment and the cable joint.

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

[0008] A cable fixing device for electric power engineering, comprising a mounting plate, on which a detection device is provided;

[0009] The mounting plate is evenly provided with fixing mechanisms, which are used to fix the cables;

[0010] The fixing mechanism includes two groups of telescopic rods symmetrically fixedly mounted on the bottom wall of the mounting plate, wherein the output ends of the two telescopic rods in each group are close to each other and are in the same straight line, an arc-shaped clamping plate is fixedly mounted on the output end of the telescopic rod, and a first plug rod is fixedly mounted on the mounting plate;

[0011] The outer cover of the mounting plate is provided with a protective cover, the bottom wall of the protective cover is open, an elastic member is installed between the inner wall of the protective cover and the mounting plate, and a second insertion rod is evenly fixed on the bottom wall of the protective cover;

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

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

[0014] First, place the mounting plate directly above the cable, and ensure that the connection between the cable and the detection device is between two adjacent fixing mechanisms. Then, place the cable between the 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 out of 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. 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 loosening 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 tightly clamp the cable. Therefore, when the rest of the cable vibrates, the probability of vibration at the connection point 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 closer to 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 of the cable to be detected is clamped by the clamps set 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 of the cable to be detected, 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] Furthermore, the gas supply mechanism includes a gas cylinder fixedly installed in the protective cover, the gas cylinder is filled with high-pressure gas, and a conduit extending into the cavity is fixedly installed on the output end of the gas cylinder.

[0022] After the protective cover is fixed to the ground, the wire hole below the cable is sealed by a 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 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, which can clean out impurities attached to the surface of the cable, increase the friction between the splint and the cable, and improve the fixing effect of the splint on the cable; and the air flow gathers in the protective cover with its 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 is gradually discharged through the gap between the bottom wall of the protective cover and the ground, thereby breaking the contact between the connection part of the cable and the detection device and the water, further reducing the influence of the impact force of the water flow on the connection part, and improving the stability during the detection process.

[0023] Furthermore, the sealing mechanism includes a semi-circular baffle rotatably mounted on the outer side wall of the protective cover, and the protective cover is provided with an adjustment mechanism for guiding the rotation of the baffle.

[0024] In the initial state, the open end of the baffle is downward, and the cable can enter the wire hole normally. When 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 gradually rotates to the bottom of the cable. At this time, the baffle blocks the part of the wire hole below the cable, and then when the gas cylinder is exhausted, 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, the water discharged from the air hole can directly impact the cable surface, thereby improving the cleaning effect of the cable.

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

[0026] Furthermore, the adjustment mechanism includes a guide groove opened on the outer wall of the protective cover, the guide groove is a semicircular ring, a moving magnet is slidably installed in the guide groove, the moving magnet is fixedly connected to the end of the outer wall of the baffle, and a reset magnet and a fixed magnet that attract each other with the moving magnet are respectively embedded at both ends of the guide groove.

[0027] In the initial state, the baffle is in an open downward state. At this time, the moving magnet and the reset magnet are attracted to each other, thereby fixing the baffle and facilitating the cable to enter the cable hole.

[0028] When the baffle state needs to be adjusted, the staff rotates the baffle, and the baffle performs a circular motion around the center of the cable. During this process, the moving magnet moves along the guide groove until the opening of the baffle is facing 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, and the baffle is fixed in the state with the opening facing upward, thereby adjusting the position of the baffle.

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

[0030] During the exhaust process of the air holes, the airflow hits the spoiler, causing the spoiler to shake and change the direction of the airflow.

[0031] When the air holes are exposed to the gas environment in the protective cover, the contact area between the airflow and the cable is increased during the shaking of the spoiler block, thereby improving the cleaning effect of the cable.

[0032] When the gas cylinder is completely deflated, the elastic rope recovers and drives the spoiler to move into the air hole, ensuring that the splint can directly contact the cable.

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

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

[0035] Furthermore, a buffer pad is fixedly mounted on the side wall of the baffle away from the protective cover. The buffer pad is in a semicircular shape, 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 fits tightly against the outer wall of the cable. When the cable that is not fixed outside the protective cover 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 pressurized tube extending into the protective cover is inserted into the side wall of the cavity.

[0038] Therefore, when the air pressure inside the protective cover increases, the high-pressure gas flows along the pressurized tube into the cavity. At this time, the air pressure inside the cavity increases, and the elastic cushion material expands, thereby increasing the contact area between the cushion and the cable. According to the pressure formula, when the contact area increases, the pressure will decrease when the pressure remains unchanged. This means that the pressure acting on a unit area decreases, thereby reducing the impact force on the cushion, thereby reducing the vibration of the cable and improving the cushion's ability to absorb the cable's kinetic energy.

[0039] Furthermore, the pressurizing tube is made of elastic material, thereby ensuring that the baffle can rotate normally.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) This solution can fix the part of the cable to be tested by the fixing mechanism through the mutual cooperation of the fixing mechanism, the protective cover, the elastic member, and the push rod. 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, and the probability of the connection part becoming loose or damaged is reduced. At the same time, the protective cover can prevent water flow from directly impacting the connection part between the cable and the detection device, thereby reducing the probability of vibration of the connection part and improving the connection stability.

[0042] (2) This solution uses the mutual cooperation of the cavity, the air hole and the gas cylinder. The high-pressure gas in the gas cylinder flows along the conduit to fill the cavity and is discharged through the air hole on the side wall of the cavity. The gas discharged from the air hole impacts the surface of the cable, which can clean the impurities attached to the surface of the cable, increase the friction between the splint and the cable, and improve the fixing effect of the splint on the cable; and the air flow is gathered in the protective cover with the 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 is gradually discharged 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 on the connection part, and improving the stability during the detection process.

[0043] (3) In this solution, the baffle rotates around the cable through the mutual cooperation of the baffle, the fixed magnet, and the moving magnet, and the baffle gradually rotates to the bottom of the cable. At this time, the baffle blocks the part of the wire hole below the cable, and then when the gas cylinder is exhausted, the cable can be separated from the water, further reducing the impact force of the water flow on the fixed cable and the probability of cable vibration. At the same time, the water flow discharged from the air hole can directly impact the cable surface, thereby improving the cleaning effect of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] Example 1:

[0054] See also Figures 1 to 6 , a cable fixing device for electric power engineering, comprising a mounting plate 1, on which a detection device 2 is provided;

[0055] The mounting plate 1 is evenly provided with fixing mechanisms, which are used to fix the cables;

[0056] The fixing mechanism includes two groups of telescopic rods 3 symmetrically fixedly mounted on the bottom wall of the mounting plate 1. The output ends of the two telescopic rods 3 in each group of telescopic rods 3 are close to each other and are in the same straight line. An arc-shaped clamping plate 4 is fixedly mounted on the output end of the telescopic rod 3, and a first insertion rod 5 is fixedly mounted 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 insertion rod 8 is evenly fixed 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] Furthermore, 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 sure the connection between the cable and the detection device 2 is between two adjacent fixing mechanisms. Then, make sure the cable is between the 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 disengage from 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 of the cable and the detection device 2, 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 part 7, preventing the impact force from being directly transmitted to the installation plate 1 and the connection between the cable and the detection device 2, further reducing the probability of loosening 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 the clamping mechanism 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 started, and the telescopic rod 3 drives the two clamping plates 4 to move closer to each other, so that the cable can be clamped by the clamping plates 4, and then the mounting plate 1 and the cable are fixed by 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 set on the mounting plate 1, 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 2 can be connected to the cable, and when reducing the vibration of the part of the cable to be detected, the connection between the connector and the cable can be prevented from loosening or being damaged, thereby ensuring the detection accuracy.

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

[0066] Wire holes 12 are symmetrically opened on the protective cover 6 , and a sealing mechanism cooperating with the wire holes 12 is provided on the protective cover 6 .

[0067] like Figure 3 As shown, the gas supply mechanism includes a gas cylinder 13 fixedly installed in the protective cover 6, the gas cylinder 13 is filled with high-pressure gas, and a conduit 14 extending into the cavity 11 is fixedly installed on the output end of the gas cylinder 13, and the conduit 14 is a hose.

[0068] After the protective cover 6 is fixed to the ground, the wire hole 12 located below the cable is sealed by the sealing mechanism, and 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 to fill the cavity 11 and is discharged through the air holes on the side wall of the cavity 11. The gas discharged from the air holes impacts the surface of the cable, which can clean out the impurities attached to the surface of the cable, increase the friction between the splint 4 and the cable, and improve the fixing effect of the splint 4 on the cable; and the air flow gathers in the protective cover 6 with its downward opening 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 is gradually discharged through the gap between the bottom wall of the protective cover 6 and the ground, thereby breaking the connection between the cable and the detection device 2 from contact with the water, further reducing the influence of the impact force of the water flow on the connection part, and improving the stability during the detection process.

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

[0070] In the initial state, the open end of the baffle 15 is downward, and the cable can enter the wire hole 12 normally. When 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 bottom of the cable. At this time, the baffle 15 blocks the part of the wire hole 12 below the cable, and then when the gas cylinder 13 is exhausted, 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, the water discharged from the air hole can directly impact the cable surface, thereby improving the cleaning effect of the cable.

[0071] In summary, under the action of the sealing mechanism, it can ensure that the detection device 2 is stably connected to the cable connection.

[0072] like Figure 6 As shown, the adjustment mechanism includes a guide groove 16 provided on the outer wall of the protective cover 6. The guide groove 16 is semicircular. A moving magnet 17 is slidably installed in the guide groove 16. The moving magnet 17 is fixedly connected to the end of the outer wall of the baffle 15, and a reset magnet 18 and a fixed magnet 19 that attract each other with the moving magnet 17 are respectively embedded at both ends of the guide groove 16.

[0073] In the initial state, the baffle 15 is in a downwardly opened state. At this time, the moving magnet 17 and the reset magnet 18 are attracted to each other, thereby fixing the baffle 15 and facilitating the entry of the cable into the cable 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 guide groove 16 until the opening of the baffle 15 is facing 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, thereby adjusting the position of the baffle 15.

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

[0076] During the exhaust process of the air holes, the airflow impacts the spoiler block 21, causing the spoiler block 21 to shake and change the direction of the airflow.

[0077] When the air holes are exposed to the gas environment in the protective cover 6, the contact area between the airflow and the cable is increased during the shaking of the spoiler 21, thereby improving the cleaning effect of the cable.

[0078] After the gas cylinder 13 has finished exhausting, the elastic rope 20 recovers and drives the spoiler 21 to move into the air hole, thereby ensuring that the clamping plate 4 can directly contact the cable.

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

[0080] As the liquid level drops, the spoiler block 21 is gradually exposed to the gas environment in the protective cover 6. At this time, the spoiler block 21 is subject to less resistance, so the spoiler block 21 will contact the cable, and under the action of the impact force of the airflow, the spoiler block 21 slides on the surface of the cable. At this time, the friction lines rub against the surface of the cable, thereby improving the cleaning effect of the cable surface.

[0081] like Figure 3 As shown, a buffer pad 22 is fixedly mounted on the side wall of the baffle 15 away from the protective cover 6. The buffer pad 22 is semicircular, 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 fits tightly against the outer wall of the cable. When the cable that is not fixed outside the protective cover 6 vibrates, it can cause 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 vibration of the cable fixed by the fixing mechanism.

[0083] like Figure 5 As shown, a cavity 23 is formed on the buffer pad 22 , and a pressurizing tube 24 extending into the protective cover 6 is inserted into the side wall of the cavity 23 .

[0084] Therefore, when the air pressure in the protective cover 6 increases, the high-pressure gas flows along the pressurized pipe 24 into the cavity 23. At this time, the air pressure in the cavity 23 increases, and the elastic cushion 22 expands, thereby increasing the contact area between the cushion 22 and the cable. According to the pressure formula, when the contact area increases, the pressure will decrease under the condition of constant pressure. This means that the pressure acting on a unit area decreases, thereby reducing the impact force on the cushion 22, thereby reducing the vibration of the cable and improving the cushion 22's ability to absorb the cable's kinetic energy.

[0085] like Figure 6 As shown, the pressurizing tube 24 is made of elastic material, thereby ensuring that the baffle 15 can rotate normally.

[0086] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
