Description

Technical Field

[0001] The present invention relates to the technical field of submarine cable installation and maintenance, and relates to H02G9 / 00, in particular to an electric wire installation device for a network switch. Background Art

[0002] In the era of deep integration of global informatization, the cross-ocean data transmission volume has shown an explosive growth. The seabed, as a key link connecting the continents, shoulders the heavy responsibility of massive data transmission. As the core device for data exchange and routing, network switches are deployed on the seabed to achieve efficient data interaction and distribution between submarine cables in different regions. It is like the "transportation hub" of the submarine communication network, ensuring that data can flow accurately and quickly between different lines to meet the growing demands of global users for real-time communication, cloud computing, big data transmission, etc.

[0003] However, the seabed environment is extremely harsh. The strong corrosiveness of seawater constantly threatens the materials of network switches and their electric wires. Under the erosion of seawater, ordinary materials may corrode and damage within a short period of time, resulting in data transmission interruption. There are strong undercurrents surging in the seabed. Their powerful impact force will not only displace the network switch, but also pull the connected electric wires, causing wire abrasion or even fracture. At the same time, the seabed geological conditions are complex and changeable, from hard reefs to soft silt, which pose great challenges to the installation and fixation of network switches. Once the network switch is not installed stably and sways under the action of external forces such as undercurrents, it is very easy to cause loose wire connections and affect the data transmission quality.

[0004] As a key component to ensure the stable operation of network switches, the connector of the submarine cable fault detection device needs to have excellent sealing performance and firm fixing performance. However, the common electric wire installation devices on the market at present expose many defects when dealing with such a complex seabed environment. In terms of sealing, it is difficult to effectively block the intrusion of seawater for a long time, so that the electric wires of the network switch are immersed in seawater for a long time, accelerating corrosion and aging, and greatly shortening the service life. In terms of fixation, the existing devices are not easy to resist adverse factors such as seabed undercurrents and complex geology, and are prone to displacement, seriously interfering with the normal operation of the network switch and adding great difficulties to subsequent maintenance work. Summary of the Invention

[0005] The present invention provides an electric wire installation device for a network switch to solve the problem that the existing devices are not easy to resist adverse factors such as seabed undercurrents and complex geology and are prone to displacement.

[0006] In order to alleviate the above technical problems, the technical solution provided by the present invention lies in:

[0007] A wire installation device for a network switch, comprising a sealing mechanism. The sealing mechanism includes a first semi-cylindrical body and a second semi-cylindrical body. The first semi-cylindrical body and the second semi-cylindrical body are snap-connected to form a cylinder, and the wire to be installed is inserted through the middle of the cylinder.

[0008] The bottom of the second semi-cylindrical body is connected with an anchoring mechanism for fixing the cylinder to the seabed.

[0009] The first semi-cylindrical body and the anchoring mechanism are jointly connected with a drainage mechanism. The drainage mechanism includes an air inlet pipe communicated with the first semi-cylindrical body. The air inlet pipe is connected to an external air supply device. The anchoring mechanism includes a drain pipe communicated with the second semi-cylindrical body and a fixing seat. A cylindrical cavity communicated with the drain pipe is opened in the fixing seat. Two sliding rods are symmetrically and slidably connected in the cylindrical cavity. One end of each of the two sliding rods, which is far away from each other, is connected with an inclined insertion rod. When the two sliding rods move away from each other, the inclined insertion rod can be inserted into the seabed.

[0010] Furthermore, the sealing mechanism further includes four arc-shaped sealing blocks connected to the two ends of the first semi-cylindrical body and the second semi-cylindrical body. The two arc-shaped sealing blocks on the same side are snap-connected to form a ring.

[0011] An arc-shaped support block is connected to the inner wall of the arc-shaped sealing block. Arc-shaped air bags are fixedly connected to both sides of the arc-shaped support block. An N-shaped limiting frame is inserted into the arc-shaped sealing block. The N-shaped limiting frame abuts against the two arc-shaped air bags. An air charging pipe is communicated with the arc-shaped air bag. The air charging pipe is communicated with the air inlet pipe through a branch pipe.

[0012] Furthermore, the drainage mechanism further includes an installation ring slidably arranged in the air inlet pipe. A round rod is slidably connected to the middle of the installation ring. A conical block is connected to the end of the round rod. A groove matched with the conical block is opened on the installation ring, and the installation ring is magnetically attracted to the conical block.

[0013] The drainage mechanism further includes an installation frame fixedly connected in the air inlet pipe. A first spring is connected between the installation frame and the installation ring. A push rod coaxially arranged with the round rod is connected to the installation frame. The diameter of the push rod is smaller than that of the round rod. After the arc-shaped air bag is filled with gas from the air inlet pipe, the branch pipe and the air charging pipe, the air pressure pushes the installation ring to slide towards the installation frame, so that the air inlet pipe is communicated with the inner cavity of the first semi-cylindrical body.

[0014] Furthermore, the anchoring mechanism further includes two rectangular blocks connected to the ends of the two sliding rods. The inclined insertion rod is fixedly connected to the rectangular block. A bracket is fixedly connected to each of the two rectangular blocks. A connecting rod is hinged to the end of each of the two brackets, and the two ends of the two connecting rods are hinged to each other.

[0015] Furthermore, the end of the branch pipe communicates with the cylindrical cavity, and the branch pipe is perpendicular to the charging pipe. A control rod is slidably connected in the branch pipe, and the control rod reciprocates vertically at the connection part of the branch pipe and the charging pipe;

[0016] When the pressure in the cylindrical cavity decreases, the control rod moves downward so that the branch pipe communicates with the charging pipe.

[0017] Furthermore, a limiting ring is fixedly connected in the branch pipe, and a second spring is connected between the limiting ring and the bottom end of the control rod.

[0018] Furthermore, a T-shaped hole is formed in the control rod. After the control rod moves downward, the branch pipe communicates with the charging pipe through the T-shaped hole.

[0019] Furthermore, a protection mechanism is further included. The protection mechanism includes two arc-shaped cylinders installed at both ends of the second semi-cylinder. A fixing frame is connected between the two arc-shaped cylinders. An arc-shaped rod is slidably connected in the arc-shaped cylinder. Two cylinders communicating with the cylindrical cavity are symmetrically connected to the fixing seat. The sliding rod is slidably connected in the cylinder, and a transmission pipe is communicated between the cylinder and the arc-shaped cylinder.

[0020] Furthermore, a mounting plate is fixedly connected to the arc-shaped cylinder. A locking pin is inserted into the mounting plate. A tension spring is connected between the pin cap of the locking pin and the mounting plate. A jack cooperating with the locking pin is formed in the arc-shaped rod.

[0021] Furthermore, a threaded rod is threadedly connected to the arc-shaped rod, and the axis of the threaded rod faces the electric wire.

[0022] The beneficial effects of the present invention are analyzed as follows:

[0023] An electric wire installation device for a network switch includes a sealing mechanism. The sealing mechanism includes a first semi-cylinder and a second semi-cylinder. The first semi-cylinder and the second semi-cylinder are buckled to form a cylinder, and the electric wire to be installed is inserted through the middle of the cylinder; an anchoring mechanism is connected to the bottom of the second semi-cylinder for fixing the cylinder to the seabed; a drainage mechanism is jointly connected to the first semi-cylinder and the anchoring mechanism. The drainage mechanism includes an air inlet pipe communicating with the first semi-cylinder. The air inlet pipe is connected to an external air supply device. The anchoring mechanism includes a drainage pipe communicating with the second semi-cylinder and a fixing seat. A cylindrical cavity communicating with the drainage pipe is formed in the fixing seat. Two sliding rods are symmetrically and slidably connected in the cylindrical cavity. Oblique insertion rods are connected to the ends of the two sliding rods away from each other. When the two sliding rods move away from each other, the oblique insertion rods can be inserted into the seabed.

[0024] The first semi-cylindrical tube is placed on the upper part. After the connection between the first semi-cylindrical tube and the second semi-cylindrical tube is completed, gas is injected into the first semi-cylindrical tube through the air inlet pipe, so that the seawater in the cylinder is squeezed by the gas and discharged. The air inlet pipe can provide gas through an air compressor or a pressure tank, etc. The seawater in the cylinder is discharged into the cylindrical cavity through the drain pipe, and the pressure in the cylindrical cavity increases, so that the sliding rod is pushed to move away from the fixed seat. When discharging air into the cylinder, the cylinder is pressed synchronously, so that the inclined insertion rod can be inserted into the seabed. The inclination of the inclined insertion rod faces the outer sliding direction of the sliding rod, so that the component motion of the inclined insertion rod can point to the seabed of the sea floor, which is convenient for the insertion of the inclined insertion rod. After the inclined insertion rod is inserted into the seabed, the cylinder is fixed for the second time to ensure that the cylinder will not move due to factors such as undersea undercurrents during the subsequent maintenance of the electric wire, and to ensure the installation and maintenance effect of the undersea cable.

[0038] Embodiment, as Figures 1-7As shown in the figure, a wire installation device for a network switch includes a sealing mechanism 100. The sealing mechanism 100 includes a first semi-cylinder 110 and a second semi-cylinder 120. The first semi-cylinder 110 and the second semi-cylinder 120 are buckled to form a cylinder, and the wire to be installed is inserted through the middle of the cylinder; the bottom of the second semi-cylinder 120 is connected with an anchoring mechanism 200 for fixing the cylinder to the seabed; a drainage mechanism 300 is jointly connected to the first semi-cylinder 110 and the anchoring mechanism 200. The drainage mechanism 300 includes an air inlet pipe 310 communicated with the first semi-cylinder 110. The air inlet pipe 310 is connected to an external air supply device. The anchoring mechanism 200 includes a drain pipe 220 communicated with the second semi-cylinder 120 and a fixing seat 210. A cylindrical cavity 211 communicated with the drain pipe 220 is opened in the fixing seat 210. Two sliding rods 230 are symmetrically and slidably connected in the cylindrical cavity 211. One end of each of the two sliding rods 230 away from each other is connected with an inclined insertion rod 250. When the two sliding rods 230 move away from each other, the inclined insertion rod 250 can be inserted into the seabed.

[0039] The working mechanism of the wire installation device for the network switch provided in this embodiment is as follows:

[0040] During use, the first semi-cylinder 110 and the second semi-cylinder 120 are buckled at the part where the cable needs to be connected or repaired. They can be connected by a hoop or bolts, etc. to ensure firmness, so that the connection point of the cable is located inside the cylinder formed by the first semi-cylinder 110 and the second semi-cylinder 120. Gloves (not shown in the figure) can be provided on the first semi-cylinder 110 or the second semi-cylinder 120 to facilitate the operation of maintenance personnel.

[0041] The first semi-cylinder 110 is placed on the upper part. After the first semi-cylinder 110 and the second semi-cylinder 120 are connected, gas is injected into the first semi-cylinder 110 through the air inlet pipe 310, so that the seawater in the cylinder is squeezed out by the gas. The air inlet pipe 310 can provide gas through an air compressor or a pressure tank, etc. The seawater in the cylinder is discharged into the cylindrical cavity 211 through the drain pipe 220. The pressure in the cylindrical cavity 211 increases, so that the sliding rod 230 is pushed to move in a direction away from the fixing seat 210. When discharging air into the cylinder, the cylinder is pressed synchronously, so that the inclined insertion rod 250 can be inserted into the seabed. The inclination of the inclined insertion rod 250 faces the outer sliding direction of the sliding rod 230, so that the component motion of the inclined insertion rod 250 can point to the seabed of the seabed, which is convenient for the insertion of the inclined insertion rod 250. After the inclined insertion rod 250 is inserted into the seabed, the cylinder is fixed for the second time to ensure that the cylinder will not move due to factors such as undersea undercurrents during the subsequent maintenance of the wire, and ensure the installation and maintenance effect of the undersea cable.

[0042] Regarding the structure of the sealing mechanism 100, specifically:

[0043] The sealing mechanism 100 further includes four arc-shaped sealing blocks 130 connected to both ends of the first semi-cylindrical barrel 110 and the second semi-cylindrical barrel 120. The two arc-shaped sealing blocks 130 on the same side are buckled with each other to form a ring; an arc-shaped support block 150 is connected to the inner wall of the arc-shaped sealing block 130, and arc-shaped air bags 160 are fixedly connected to both sides of the arc-shaped support block 150. An N-shaped limiting frame 140 is inserted into the arc-shaped sealing block 130, and the N-shaped limiting frame 140 abuts against the two arc-shaped air bags 160. An air charging pipe 372 is communicated with the arc-shaped air bag 160, and the air charging pipe 372 is communicated with the air inlet pipe 310 through a branch pipe 320.

[0044] After the first semi-cylindrical barrel 110 and the second semi-cylindrical barrel 120 are connected, the four arc-shaped sealing blocks 130 on both sides of them are buckled in pairs to form two rings, and the two corresponding arc-shaped support blocks 150 also contact each other to form a support ring. Two groups of arc-shaped air bags 160 are symmetrically arranged on both sides of the arc-shaped support block 150. The arc-shaped support block 150 is inserted into the arc-shaped sealing block 130, so that the arc-shaped air bag 160 is clamped in the middle of the arc-shaped support block 150. When gas is filled into the air inlet pipe 310, the gas is diverted into the air charging pipe 372, so that the arc-shaped air bag 160 is inflated and expanded, and the arc-shaped air bag 160 approaches and fits the cable under the squeezing and guiding action of the N-shaped limiting frame 140 and the arc-shaped support block 150, so that the inner cavities of the first semi-cylindrical barrel 110 and the second semi-cylindrical barrel 120 are in a sealed state.

[0045] Regarding the structure of the drainage mechanism 300, specifically:

[0046] The drainage mechanism 300 further includes a mounting ring 360 sliding in the air inlet pipe 310. A round rod 362 is slidably connected to the middle of the mounting ring 360. A conical block 361 is connected to the end of the round rod 362. A groove matching with the conical block 361 is opened on the mounting ring 360, and the mounting ring 360 is magnetically attracted to the conical block 361; the drainage mechanism 300 further includes a mounting frame 330 fixedly connected in the air inlet pipe 310. A first spring 350 is connected between the mounting frame 330 and the mounting ring 360. A push rod 340 coaxially arranged with the round rod 362 is connected to the mounting frame 330. The diameter of the push rod 340 is smaller than that of the round rod 362. After the gas fills the arc-shaped air bag 160 from the air inlet pipe 310, the branch pipe 320 and the air charging pipe 372, the air pressure pushes the mounting ring 360 to slide towards the mounting frame 330, so that the air inlet pipe 310 is communicated with the inner cavity of the first semi-cylindrical barrel 110.

[0047] In the initial state, the first spring 350 applies a thrust to the mounting ring 360, so that the push rod 340 is away from the round rod 362, so that the round rod 362 is not pushed. At this time, the mounting ring 360 is magnetically attracted to the conical block 361, and the gas will not enter the inner cavity of the cylinder through the air inlet pipe 310. At this time, the gas first enters the arc-shaped airbag 160 through the air inlet pipe 310, the branch pipe 320 and the inflation pipe 372, so that the arc-shaped airbag 160 expands. After the arc-shaped airbag 160 expands to completely fit the wire to be installed, the air pressure gradually increases, so that the increase in air pressure can push the mounting ring 360 to overcome the elastic force of the first spring 350 and approach the push rod 340. At this time, the push rod 340 pushes the round rod 362, so that the conical block 361 is separated from the contact with the mounting ring 360, so that the gas can flow to the inner cavity of the cylinder through the air inlet pipe 310, so that the seawater in the cylinder is discharged, ensuring that the cylinder performs the drainage operation only when the air tightness is good.

[0048] Regarding the structure of the anchoring mechanism 200, specifically:

[0049] The anchoring mechanism 200 also includes two rectangular blocks 240 connected to the ends of the two sliding rods 230, and the oblique rod 250 is fixedly connected to the rectangular blocks 240. The two rectangular blocks 240 are fixedly connected with brackets 260, and the ends between the two are hinged with connecting rods 270, and the two ends of the two connecting rods 270 are hinged to each other.

[0050] When the two rectangular blocks 240 move away from each other, the two rectangular blocks 240 pull the connecting rod 270 to swing through the bracket 260. Since the ends of the connecting rod 270 are hinged to each other, and the distance between the hinged parts of the bracket 260 and the connecting rod 270 and the corresponding rectangular blocks 240 is greater than the distance between the hinged parts of the two connecting rods 270 and the corresponding rectangular blocks 240, the hinged parts of the two connecting rods 270 can move downward and approach the seabed, so that the connecting rod 270 can be inserted into the seabed, further improving the installation firmness of the device.

[0051] Among the optional methods of this embodiment, the more preferred ones are:

[0052] The end of the branch pipe 320 is connected to the cylindrical cavity 211, and the branch pipe 320 is perpendicular to the inflation tube 372. A control rod 370 is slidably connected inside the branch pipe 320, and the control rod 370 vertically reciprocates at the connection between the branch pipe 320 and the inflation tube 372; when the pressure in the cylindrical cavity 211 decreases, the control rod 370 moves downward to connect the branch pipe 320 with the inflation tube 372.

[0053] When air is injected into the cylinder through the intake pipe 310, the seawater in the cylinder enters the cylindrical cavity 211 through the drain pipe 220. Since the branch pipe 320 is connected to the cylindrical cavity 211, the pressure of the discharged seawater can be conducted into the branch pipe 320. When the airtightness of the cylinder is good, the pressure can push the control rod 370 upward. At this time, the branch pipe 320 is not connected to the inflatable pipe 372, maintaining the drainage state of the cylinder. When the contact part between the cylinder and the wire leaks, the pressure in the cylindrical cavity 211 will decrease, so that the control rod 370 moves downward, making the branch pipe 320 connected to the inflatable pipe 372. Thus, gas can enter the arc-shaped airbag 160, enabling the arc-shaped airbag 160 to continue to expand and block the gap between the cylinder and the wire.

[0054] In an alternative embodiment of the present embodiment, preferably:

[0055] A limiting ring 380 is fixedly connected inside the branch pipe 320, and a second spring 390 is connected between the limiting ring 380 and the bottom end of the control rod 370.

[0056] The second spring 390 provides a pulling force for the control rod 370, fixing the lower limit position of the movement of the control rod 370, that is, when the control rod 370 is at the lowest part of the stroke, the branch pipe 320 is connected to the inflatable pipe 372. When the pressure transmitted by the cylindrical cavity 211 is sufficient, it can overcome the pulling force of the second spring 390 to make the control rod 370 move upward. After the cylinder leaks, the second spring 390 can pull the control rod 370 downward, enabling the branch pipe 320 to be connected to the inflatable pipe 372.

[0057] In an alternative embodiment of the present embodiment, preferably:

[0058] A T-shaped hole 371 is formed in the control rod 370. After the control rod 370 moves downward, the branch pipe 320 is connected to the inflatable pipe 372 through the T-shaped hole 371.

[0059] By providing the T-shaped hole 371, the movement stroke of the control rod 370 can be shortened. Thus, by moving the control rod 370 by a distance equal to the diameter of the T-shaped hole 371, the on-off control of the branch pipe 320 and the inflatable pipe 372 can be achieved, enabling the operation of inflating the arc-shaped airbag 160 in a timely manner after the leakage of the cylinder occurs.

[0060] Regarding the structure of the protection mechanism 400, specifically:

[0061] The protection mechanism 400 includes two arc-shaped cylinders 410 installed at both ends of the second semi-cylindrical tube 120. A fixing frame 450 is connected between the two arc-shaped cylinders 410. An arc-shaped rod 420 is slidably connected inside the arc-shaped cylinder 410. Two cylinders 212 communicating with the cylindrical cavity 211 are symmetrically connected to the fixing seat 210. A sliding rod 230 is slidably connected inside the cylinder 212. A transmission pipe 411 is connected between the cylinder 212 and the arc-shaped cylinder 410.

[0062] There is a clearance fit between the arc-shaped cylinder 410 and the arc-shaped rod 420, with a tiny gap left between them. Seawater inside the cylinder enters the cylindrical cavity 211 through the drain pipe 220, causing the sliding rod 230 to be pushed and move outward. After the sliding rod 230 moves to its maximum outward stroke, the cylinder 212 can communicate with the arc-shaped cylinder 410 through the transmission pipe 411. At this time, seawater enters the arc-shaped cylinder 410 and pushes the arc-shaped rod 420 out.

[0063] In an alternative embodiment of the present example, preferably:

[0064] An installation plate 430 is fixedly connected to the arc-shaped cylinder 410. A locking pin 431 is inserted into the installation plate 430. A tension spring 432 is connected between the pin cap of the locking pin 431 and the installation plate 430. A jack cooperating with the locking pin 431 is provided on the arc-shaped rod 420.

[0065] After the arc-shaped rod 420 slides out, it can form a ring with the arc-shaped cylinder 410. And after the arc-shaped rod 420 extends, it can push the locking pin 431 to slide against the tension of the tension spring 432. Subsequently, the arc-shaped rod 420 continues to move. After the jack on the arc-shaped rod 420 moves to the position of the locking pin 431, the locking pin 431 is inserted into the jack to fix the arc-shaped rod 420.

[0066] In an alternative embodiment of the present example, preferably:

[0067] A threaded rod 440 is threadedly connected to the arc-shaped rod 420, and the axis of the threaded rod 440 faces the electric wire.

[0068] After the arc-shaped rod 420 is fixed to the arc-shaped cylinder 410, the threaded rod 440 is tightened so that the end of the threaded rod 440 abuts against the electric wire, thereby ensuring the relative fixation of the positions of the arc-shaped rod 420 and the electric wire. And the two arc-shaped cylinders 410 are fixedly connected through the fixing frame 450, so that the electric wire between the two arc-shaped cylinders 410 is straight and will not bend, ensuring that the connection part of the connected electric wire will not swing with the flow of seawater and ensuring the firmness of its connection.

[0069] The arc-shaped cylinder 410 is installed at the end of the second semi-cylinder 120 through the clamping block 460. The clamping block 460 and the second semi-cylinder 120 can be connected by bolts. After the wiring is completed, the clamping block 460 is removed, and then the first semi-cylinder 110 and the second semi-cylinder 120 are removed. At this time, the connection and installation of the wire are completed.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
