[0001] The invention belongs to the technical field of cable protection, and in particular relates to a protective device for ship outdoor cables. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Cables need to be installed on ships to transmit signals. However, during the voyage of the ship, the ship often rises and falls with the wind and waves.

[0003] The protective device of the ship's open-air cable is used to fix and protect the cable. At the same time, both ends of the protective device of the ship's open-air cable are fixedly connected to a fixed foundation on the ship through a fixing component.

[0004] When the ship is shaking, the fixing components at both ends of the ship's outdoor cable protection device are fixedly connected to the fixed foundations on both sides. Due to the shaking of the ship, the fixed foundations on both sides of the ship's outdoor cable protection device are prone to vertical vibration, and the fixing components at one end of the ship's outdoor cable protection device are prone to loosening or breaking, causing the cable pipeline to move or bend at will; When the ship shakes, the fixed foundations on the ship move horizontally relative to each other and rise vertically relative to each other at the same time, which will cause the protective devices of the ship's outdoor cables between the fixed foundations to be subjected to an extrusion force oblique to the horizontal, which may easily cause the protective devices of the ship's outdoor cables to deform and be damaged, thereby losing their protective function.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

The height of the fixed frame driven by the connection assembly can offset the height of the sliding seat when it moves upward, so as to avoid excessive support force on the cable tube caused by the lifting of the fixed frame when the sliding seat moves upward, thereby causing the cable tube to bend; and ensure the height stability of the cable tube when the fixed foundations on both sides vibrate vertically; 3. At this time, if the cable tube and the support seat are squeezed too tightly, the support seat will close the through hole on the side wall of the base and one end of the hose. When the gas in the No. 1 cavity is transported to the gas pipe, the gas enters the No. 2 cavity through the No. 2 outlet valve. Then, under the action of the gas pressure, the No. 3 piston rod slides outward along the piston cylinder, and the No. 3 piston rod drives the fixing frame to move downward, thereby reducing the pressure between the cable tube and the support seat; at this time, if the squeezing force between the cable tube and the support seat is small, the hose and the through hole in the support seat are connected, and when the gas in the No. 1 cavity is transported to the gas pipe, the gas pipe discharges the gas to the outside of the device through the hose, thereby avoiding the fixing frame moving downward and causing insufficient support for the cable tube; 4. When the sliding seat moves upward, the sliding seat drives the limit plate to move upward. At this time, the protective component and the limit plate slide relative to each other. The sliding cooperation between the protective component and the limit plate can prevent the horizontal limit protection of the cable tube from being damaged when the fixed foundations on both sides vibrate vertically; 5. When the fixed foundations on both sides vibrate vertically and produce a height difference, the No. 1 piston rod on the side where the fixed seat is raised contracts toward the No. 1 fixed sleeve. At this time, the pressure in the closed groove cavity increases, and the lubricating oil in the closed groove cavity is transported to the side wall of the limit plate through the oil pipe, thereby reducing the friction between the telescopic part and the limit plate, avoiding excessive friction between the fixed frame and the limit plate and making it impossible to adjust and move.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments; it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 7As shown, a protective device for ship outdoor cables provided by the present invention comprises two fixing seats 1, each of the fixing seats 1 is fixedly connected to a fixing rod 2, and one end of each of the fixing rods 2 is fixedly connected to a baffle 3; The two fixed rods 2 are slidably connected to a sliding seat 10, an elastic component 4 is fixedly arranged between the sliding seat 10 and the two fixed seats 1, and a limiting component 5 is fixedly arranged between the sliding seat 10 and the two baffles 3; The sliding seat 10 is fixedly provided with a connecting component 6, and the connecting component 6 can be vertically extended and retracted. One end of the connecting component 6 is fixedly connected to a fixing frame 12, and the fixing frame 12 is slidably connected to two limiting plates 11. The fixing frame 12 is fixedly connected to a supporting component 7, and the supporting component 7 can support and limit the cable tube 21; A protective component 8 is vertically slidably connected to one side of the limit plate 11, and the protective component 8 is horizontally slidably connected to the fixed seat 1. A pipeline component 9 is connected between the connecting component 6 and the limit component 5. When the limit component 5 is extended, the pipeline component 9 can transport gas to the connecting component 6, thereby pushing the connecting component 6 to extend.

[0021] In this embodiment, the cable is protected by the cable tube 21, the cable tube 21 passes through the fixing frame 12, and the support assembly 7 can support and limit the cable tube 21; the two fixing seats 1 are respectively fixedly connected to the fixed foundation of the ship board by bolts, and at this time, the protection assembly 8 pushes the limiting plate 11 to clamp and fix the cable tube 21; When the ship shakes, the fixed foundation on the ship moves horizontally relatively, and the protection component 8 pushes the limit plate 11 to elastically protect the cable tube 21, thereby preventing the cable tube 21 from being damaged due to rigid impact; When the fixed foundations on both sides vibrate vertically and produce a height difference: exist Figure 1 In the embodiment, if the fixed seat 1 on the left side is raised, the fixed seat 1 on the left side pushes the sliding seat 10 upward through the elastic component 4, and the elastic component 4 is compressed. Since the elastic component 4 is compressed, the sliding seat 10 on the left side is close to the fixed seat 1 on the left side, and the limiting component 5 between the sliding seat 10 on the left side and the baffle 3 is extended; and the height of the fixed seat 1 on the right side is lower than that of the fixed seat 1 on the left side, so at this time, the limiting component 5 on the right side elastically limits the sliding seat 10, and the limiting component 5 on the right side is compressed at the same time, and the sliding seat 10 on the right side is close to the baffle 3, so the elastic component 4 between the sliding seat 10 on the right side and the fixed seat 1 is extended; If the right fixing seat 1 is raised, the right fixing seat 1 pushes the sliding seat 10 upward through the elastic component 4; The cooperation of the elastic component 4 and the limit component 5 can prevent the fixing base 1 from falling off from the fixing base when the fixing bases on both sides vibrate vertically and generate a height difference. When the fixed foundations on both sides vibrate vertically and generate a height difference, the limit assembly 5 on the left or right side extends, and the pipeline assembly 9 can deliver gas to the connecting assembly 6, thereby pushing the connecting assembly 6 to extend. At this time, the connecting assembly 6 drives the fixing frame 12 to drop in height; the height of the fixing frame 12 driven by the connecting assembly 6 to drop can offset the height of the sliding seat 10 moving up, thereby preventing the fixing frame 12 from lifting too much support force on the cable tube 21 when the sliding seat 10 moves up, thereby causing the cable tube 21 to bend; ensuring the height stability of the cable tube 21 when the fixed foundations on both sides vibrate vertically; When the sliding seat 10 moves upward, the sliding seat 10 drives the limit plate 11 to move upward. At this time, the protective component 8 and the limit plate 11 slide relatively. The sliding cooperation between the protective component 8 and the limit plate 11 can prevent the horizontal limit protection of the cable tube 21 from being damaged when the fixed foundations on both sides vibrate vertically.

[0022] like Figure 2 As shown, as a preferred embodiment of the present invention, the elastic component 4 includes a No. 1 piston rod 41 and a No. 1 fixed sleeve 42; the No. 1 piston rod 41 is a hollow rod, the No. 1 piston rod 41 is slidably sleeved outside the fixed rod 2, and the No. 1 piston rod 41 is sealed and connected with the fixed rod 2, the No. 1 piston rod 41 is slidably and sealedly connected with the No. 1 fixed sleeve 42, an elastic member is connected between the inner end surface of the No. 1 fixed sleeve 42 and the No. 1 piston rod 41, the No. 1 piston rod 41 is fixedly connected with the sliding seat 10, and the No. 1 fixed sleeve 42 is fixedly connected with the fixed seat 1; In this embodiment, the elastic member elastically supports the sliding seat 10 by pushing the No. 1 piston rod 41, so that when a height difference occurs vertically between the fixed bases on both sides, the two fixed bases 1 can always be fixedly connected to the fixed bases on both sides.

[0023] like Figure 4 As shown, as a preferred embodiment of the present invention, the limiting assembly 5 includes a No. 2 piston rod 51, a No. 2 fixed sleeve 52 and a No. 2 spring 53; the No. 2 piston rod 51 is a hollow rod, and the No. 2 piston rod 51 is slidably sleeved outside the fixed rod 2, and the No. 2 piston rod 51 is sealed and connected to the fixed rod 2, the No. 2 piston rod 51 is slidably and sealingly connected to the No. 2 fixed sleeve 52, the No. 2 spring 53 is connected between the inner end surface of the No. 2 fixed sleeve 52 and the No. 2 piston rod 51, the No. 2 piston rod 51 is fixedly connected to the sliding seat 10, and the No. 2 fixed sleeve 52 is fixedly connected to the baffle 3; in this embodiment, the No. 2 spring 53 pushes the No. 2 piston rod 51 to elastically limit the sliding seat 10.

[0024] like Figure 5As shown, as a preferred embodiment of the present invention, the connecting assembly 6 includes a No. 3 piston rod 61, a piston cylinder 62 and a No. 3 spring 63; the piston cylinder 62 is fixedly connected to the sliding seat 10, the No. 3 piston rod 61 is fixedly connected to the fixing frame 12, the No. 3 piston rod 61 is slidably and sealingly connected to the piston cylinder 62, and the No. 3 spring 63 is connected between the piston cylinder 62 and the No. 3 piston rod 61; Under the action of the No. 3 spring 63, the No. 3 piston rod 61 elastically supports the fixed frame 12. When the pipeline assembly 9 delivers gas to the piston cylinder 62, under the action of the gas pressure, the No. 3 piston rod 61 slides outward along the piston cylinder 62, and the No. 3 piston rod 61 drives the fixed frame 12 to move downward.

[0025] like Figure 7 As shown, as a preferred embodiment of the present invention, the support assembly 7 includes a support seat 71, a base 72 and a No. 4 spring 73; the base 72 is fixedly connected to the fixing frame 12, the support seat 71 is slidably connected to the base 72, and the No. 4 spring 73 is arranged between the support seat 71 and the base 72; in the support assembly 7, the No. 4 spring 73 pushes the support seat 71 to elastically support the cable tube 21.

[0026] like Figure 2 As shown, as a preferred embodiment of the present invention, the protective assembly 8 includes a moving seat 81 and a telescopic member 82, the moving seat 81 is slidably connected to the sliding seat 10, the telescopic member 82 is fixedly connected to the moving seat 81, and one end of the telescopic member 82 is slidably connected to the limiting plate 11, and the telescopic member 82 can be elastically telescopic; When the fixed foundation on the ship moves horizontally relative to each other, the fixed foundation on the ship squeezes the movable seat 81 toward the middle, and the movable seat 81 pushes the telescopic member 82. The telescopic member 82 reduces the horizontal impact force during an earthquake by elastic expansion and contraction; and one end of the telescopic member 82 slides with the fixed frame 12, so that the fixed foundations on both sides vibrate vertically. When the fixed frame 12 moves vertically, the rigid destruction between the telescopic member 82 and the limiting plate 11 can be avoided.

[0027] like Figure 1 and Figure 3As shown, as a preferred embodiment of the present invention, the pipeline assembly 9 includes an air supply pipe 91, an air inlet valve 92, and a No. 1 air outlet valve 93; a closed No. 1 cavity 13 is provided between the No. 2 piston rod 51 and the No. 2 fixed sleeve 52, and the No. 1 cavity 13 is away from the No. 2 spring 53; a closed No. 2 cavity 14 is provided between the No. 3 piston rod 61 and the piston cylinder 62, and the No. 2 cavity 14 is away from the No. 3 spring 63; the air supply pipe 91 is connected between the No. 1 cavity 13 and the No. 2 cavity 14, the air inlet valve 92 is provided on the No. 2 piston rod 51, and the No. 1 air outlet valve 93 is provided on the air supply pipe 91, the air inlet valve 92 unidirectionally inhales air into the No. 1 cavity 13, and the No. 1 air outlet valve 93 unidirectionally exhausts air into the No. 2 cavity 14; When the limit assembly 5 on the left side is extended and the No. 2 piston rod 51 slides to the outside of the No. 2 fixing sleeve 52, the air pressure in the No. 1 cavity 13 increases, and the gas in the No. 1 cavity 13 enters the No. 2 cavity 14 through the gas pipe 91. At this time, the air pressure in the No. 2 cavity 14 increases. Under the action of the air pressure, the No. 3 piston rod 61 slides outward along the piston cylinder 62, and the No. 3 piston rod 61 drives the fixing frame 12 to move downward.

[0028] like Figure 3 and Figure 5 As shown, as a preferred embodiment of the present invention, a No. 2 air outlet valve 15 is provided on the air supply pipe 91, and a hose 16 is provided between the No. 1 air outlet valve 93 and the No. 2 air outlet valve 15. The hose 16 is connected to the base 72 through the air channel in the fixed frame 12, and the base 72 is provided with a through hole 17 connected to the outside.

[0029] When the cable tube 21 and the support seat 71 are squeezed too tight, the support seat 71 closes the through hole 17 on the side wall of the base 72 and one end of the hose 16. When the gas in the No. 1 cavity 13 is transported to the gas pipe 91, the gas enters the No. 2 cavity 14 through the No. 2 gas outlet valve 15. Then, under the action of the gas pressure, the No. 3 piston rod 61 slides outward along the piston cylinder 62, and the No. 3 piston rod 61 drives the fixing frame 12 to move downward, thereby reducing the pressure between the cable tube 21 and the support seat 71. When the squeezing pressure between the cable tube 21 and the support seat 71 is small, the hose 16 and the through hole 17 in the support seat 71 are connected. When the gas in the No. 1 cavity 13 is transported to the gas pipe 91, the gas pipe 91 discharges the gas to the outside of the device through the hose 16, thereby preventing the fixing frame 12 from moving downward and causing insufficient supporting force for the cable tube 21.

[0030] like Figure 2As shown, as a preferred embodiment of the present invention, a closed groove cavity is formed between the No. 1 piston rod 41 and the No. 1 fixed sleeve 42, the two limit plates 11 are connected by an oil pipe 19, and the two ends of the oil pipe 19 are respectively connected to the two No. 1 fixed sleeves 42, the oil pipe 19 is provided with an oil drip hole on the upper side of the limit plate 11, the closed groove cavity is connected to the outside through an air valve 18 for one-way air intake to the closed groove cavity, and the closed groove cavity is connected to the oil pipe 19 through an oil valve 20 for one-way oil discharge to the oil pipe 19; When the fixed foundations on both sides vibrate vertically and produce a height difference, the No. 1 piston rod 41 on the raised side of the fixed seat 1 contracts toward the No. 1 fixed sleeve 42. At this time, the pressure in the closed groove cavity increases, and the lubricating oil in the closed groove cavity is transported to the side wall of the limit plate 11 through the oil pipe 19, thereby reducing the friction between the telescopic member 82 and the limit plate 11, avoiding excessive friction between the fixed frame 12 and the limit plate 11 and making it impossible to adjust and move.

[0031] Working principle: The cables are protected by the cable tube 21, which passes through the fixing frame 12, and the supporting assembly 7 can support and limit the cable tube 21; the two fixing seats 1 are respectively fixedly connected to the fixed basis of the ship deck by bolts, and at this time the protective assembly 8 pushes the limiting plate 11 to clamp and fix the cable tube 21.

[0032] When the ship shakes, the fixed foundation on the ship moves horizontally relatively, and the protection component 8 pushes the limit plate 11 to elastically protect the cable tube 21 to prevent the cable tube 21 from being damaged due to rigid impact.

[0033] When the fixed foundations on both sides vibrate vertically and produce a height difference: exist Figure 1 In the embodiment, if the fixed seat 1 on the left side is raised, the fixed seat 1 on the left side pushes the sliding seat 10 to move upward through the elastic component 4, and the elastic component 4 is compressed. Due to the compression of the elastic component 4, the sliding seat 10 on the left side is close to the fixed seat 1 on the left side, and the limiting component 5 between the sliding seat 10 on the left side and the baffle 3 is extended; and the height of the fixed seat 1 on the right side is lower than that of the fixed seat 1 on the left side, so at this time, the limiting component 5 on the right side elastically limits the sliding seat 10, and the limiting component 5 on the right side is compressed at the same time, and the sliding seat 10 on the right side is close to the baffle 3, so the elastic component 4 between the sliding seat 10 on the right side and the fixed seat 1 is extended; on the contrary, if the fixed seat 1 on the right side is raised, the fixed seat 1 on the right side also pushes the sliding seat 10 to move upward through the elastic component 4; Through the cooperation of the elastic component 4 and the limiting component 5, it is possible to prevent the fixing seat 1 from falling off from the fixing foundation when the fixing foundations on both sides vibrate vertically and generate a height difference.

[0034] When the fixed foundations on both sides vibrate vertically and generate a height difference, the limit assembly 5 on the left or right side extends, and the pipeline assembly 9 can deliver gas to the connecting assembly 6, thereby pushing the connecting assembly 6 to extend. At this time, the connecting assembly 6 drives the fixing frame 12 to drop in height; the height of the fixing frame 12 driven by the connecting assembly 6 to drop can offset the height of the sliding seat 10 moving up, thereby preventing the fixing frame 12 from lifting too much support force on the cable tube 21 when the sliding seat 10 moves up, thereby causing the cable tube 21 to bend; ensuring the height stability of the cable tube 21 when the fixed foundations on both sides vibrate vertically; When the limit assembly 5 on the left side is extended and the No. 2 piston rod 51 slides toward the outside of the No. 2 fixing sleeve 52, the air pressure in the No. 1 cavity 13 increases, and the gas in the No. 1 cavity 13 enters the No. 2 cavity 14 through the gas pipe 91; at this time, if the cable tube 21 and the support seat 71 are squeezed too tightly, the support seat 71 closes the through hole 17 on the side wall of the base 72 and one end of the hose 16, and when the gas in the No. 1 cavity 13 is transported to the gas pipe 91, the gas enters the No. 2 cavity 14 through the No. 2 gas outlet valve 15, and then the gas pressure is increased. Under the action of force, the No. 3 piston rod 61 slides outward along the piston cylinder 62, and the No. 3 piston rod 61 drives the fixing frame 12 to move downward, thereby reducing the pressure between the cable tube 21 and the support seat 71; at this time, if the extrusion force between the cable tube 21 and the support seat 71 is small, the hose 16 and the through hole 17 in the support seat 71 are connected, and when the gas in the No. 1 cavity 13 is transported to the gas pipe 91, the gas pipe 91 discharges the gas to the outside of the device through the hose 16, thereby avoiding the fixing frame 12 moving downward and causing insufficient supporting force on the cable tube 21.

[0035] When the sliding seat 10 moves upward, the sliding seat 10 drives the limit plate 11 to move upward, and the protection component 8 and the limit plate 11 slide relative to each other. The sliding cooperation between the protection component 8 and the limit plate 11 can prevent the horizontal limit protection of the cable tube 21 from being damaged when the fixed foundations on both sides vibrate vertically. When the fixed foundations on both sides vibrate vertically and produce a height difference, the No. 1 piston rod 41 on the raised side of the fixed seat 1 contracts toward the No. 1 fixed sleeve 42. At this time, the pressure in the closed groove cavity increases, and the lubricating oil in the closed groove cavity is transported to the side wall of the limit plate 11 through the oil pipe 19, thereby reducing the friction between the telescopic member 82 and the limit plate 11, avoiding excessive friction between the fixed frame 12 and the limit plate 11 and making it impossible to adjust and move.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
