Description

Technical Field

[0001] The present invention relates to the technical field of power pipes, and particularly relates to an HPVC power pipe and a bracket for underwater use. Background Art

[0002] The underwater laying of cables mainly includes three stages: cable route exploration and cleaning, cable laying, and scour and burial protection. In the process of laying submarine cables, professional laying vessels are usually required, especially for the laying of submarine cables.

[0003] During the cable erection process, when encountering shallow water areas (such as lakes and rivers) with a relatively large obstruction width, the following measures are often taken:

[0004] 1. Installing cable towers to cross the shallow water area, but this measure will damage the ecological environment of the shallow water area;

[0005] 2. Bypassing for erection, but this measure usually needs to consider various factors such as the safety of residents and land occupation, and at the same time, the cost is relatively high;

[0006] 3. Underwater laying.

[0007] Compared with the first two measures, underwater laying is more convenient and fast, but the current underwater cable laying measures have several problems: 1. Since the water depth in most areas of the shallow water area is less than 3 meters, there is often a risk of stranding when using professional laying vessels for laying; 2. If directly using submarine cables for laying, although submarine cables have the advantages of high corrosion resistance, high insulation, and high firmness, the cost of submarine cables is expensive; 3. If using ordinary cables, although the cost is relatively low, the corrosion resistance and firmness of ordinary cables are relatively low.

[0008] Therefore, it is necessary to invent a power pipe that is both convenient for shallow water laying and can protect ordinary cables against water and impact, thereby reducing the overall laying cost. Summary of the Invention

[0015] Further, a drain hole is arranged on the slot, and a one-way valve is arranged in the drain hole.

[0016] A bracket structure includes a clamping mechanism. Fixed mechanisms are respectively connected to both sides of the clamping mechanism. A pipe hoop mechanism is installed on the clamping mechanism. The pipe hoop mechanism includes a first clamp and a second clamp.

[0046] Embodiment:

[0047] As Figure 3As shown in the figure, an HPVC power pipe for underwater use, the HPVC power pipe 100 includes an inner pipe 109. Fixed rings 1122 are respectively and fixedly installed at both ends of the inner pipe 109. A second waterproof film 1127 is provided on the fixed rings 1122. And slots 104 and plugs 105 are respectively provided on one side of the two fixed rings 1122 away from the inner pipe 109. A carbon ring 113 is provided inside the plug 105, and the carbon ring 113 is inside the first waterproof film 114; One end of the plug 105 away from the fixed ring 1122 is provided with a first waterproof film 114; Specifically, the inner pipe 109, the fixed rings 1122, the slots 104 and the plugs 105 have the same inner diameter. Two adjacent HPVC power pipes 100 are connected through the adjacent slots 104 and plugs 105. In this embodiment, the inner pipe 109 and the outer pipe 101 are made of HPVC. The film-breaking mechanism 112 includes a rotating ring 1121, a fixed ring 1122, a sliding plate 1123, a limiting groove 1124, a driving column 1125, a tension spring 1126, a second waterproof film 1127 and a sharp cone 1128. The film-breaking mechanism 112 is installed at both ends of the inner pipe 109 and is located inside the outer pipe 101. Sealing grooves 111 are provided at positions of the outer pipe 101 close to both ends;

[0048] Reference Figure 2 and 3 , the HPVC power pipe 100 further includes an outer pipe 101. The outer pipe 101 is arranged outside the inner pipe 109, and both ends of the outer pipe 101 are respectively fixedly connected to the slots 104 and the plugs 105. Two groups of sealing partitions 116 are arranged between the outer pipe 101 and the inner pipe 109. A sealing plug 117 is arranged on the outer pipe 101, and the sealing plug 117 is located between the two groups of sealing partitions 116. When in use, the HPVC power pipe 100 is sent to the designated water surface, and then the water is allowed to enter the space between the outer pipe 101, the inner pipe 109 and the two groups of sealing partitions 116 by manually pulling out the sealing plug 117, so that the HPVC power pipe 100 sinks to the bottom of the water, and the sealing plug 117 is plugged, which is convenient for subsequent operations. The outer pipe 101 plays a role of waterproofing and protection, and is used to prevent water from entering the inner pipe 109. The rotating ring 1121 is rotatably installed on the outside of the fixed ring 1122, and the sliding plate 1123 (reference Figure 10 ) is rotatably installed on the fixed ring 1122. And a limiting groove 1124 is provided on one side of the rotating ring 1121 close to the sliding plate 1123. A sliding rod of the sliding plate 1123 is slidably installed in the limiting groove 1124; The limiting groove 1124 is composed of a shallow groove and a deep groove connected by a transition (reference Figure 11 ), the deep groove is located at one end of the rotating ring 1121 away from the fixed ring 1122, and the shallow groove is located on the side close to the fixed ring 1122. The sliding rod on the sliding plate 1123 is slidably installed in the limiting groove 1124.

[0049] Specifically, at the initial position, the ends of the five sliding plates 1123 with pointed cones 1128 gather at the center of the second waterproof membrane 1127. The sliding rods of the second waterproof membrane 1127 are located at the shallow groove end of the limiting groove 1124 close to the fixed ring 1122. At this time, the pointed cones 1128 do not contact the second waterproof membrane 1127. When the driving mechanism drives the rotating ring 1121 to rotate, the rotating ring 1121 drives the limiting groove 1124 to rotate. As the sliding rods of the sliding plates 1123 move from the shallow groove to the deep groove of the limiting groove 1124, the pointed cones 1128 of the sliding plates 1123 move towards the second waterproof membrane 1127 under the pulling of the tension springs 1126 and penetrate the second waterproof membrane 1127. Then, the limiting groove 1124 drives the pointed cones 1128 to move and cut open the second waterproof membrane 1127, as Figure 11 shown, Figure 11 the curve on the second waterproof membrane 1127 in Figure 11 is the moving curve of the pointed cone 1128. At the same time, the pointed cone 1128 near the plug 105 cuts open the second waterproof membrane 1127 and the first waterproof membrane 114 simultaneously. And a pointed cone 1128 is provided at another corner of the sliding plate 1123 (refer to Figure 12 and 13 ); A driving mechanism is installed between the outer tube 101 and the inner tube 109, and the driving mechanism is in transmission connection with the rotating ring 1121.

[0050] Refer to Figure 13 , the rod of the sliding plate 1123 is rotatably installed in the round hole of the fixed ring 1122, and a tension spring 1126 is arranged in the round hole of the fixed ring 1122. One end of the tension spring 1126 is relatively rotatably connected to the fixed ring 1122, and the other end is fixedly connected to the rod of the sliding plate 1123. The sliding plate 1123 exerts a pulling force to move the sliding plate 1123 towards the fixed ring 1122.

[0051] Refer to Figure 5 , the driving mechanism includes a first bevel gear 106 rotatably installed between the inner tube 109 and the outer tube 101. The second bevel gear 107 meshes with the first bevel gear 106, and the second bevel gear 107 is fixedly installed on the transmission shaft 108; The transmission shaft 108 is rotatably installed inside the outer tube 101. Both ends of the transmission shaft 108 pass through two groups of sealing partitions 116 respectively, and the transmission shaft 108 is in sealed rotation connection with the sealing partitions 116. Both ends of the transmission shaft 108 are respectively provided with a clamping wheel 115, and the clamping wheel 115 meshes with a number of driving columns 1125 arranged on the rotating ring 1121. Refer to Figure 6 and 7 , a semi-circular ring 102 is slidably installed on the outer tube 101, and a first clamping frame 103 is slidably installed on the outer tube 101. The long clamping column of the first clamping frame 103 passes through the outer tube 101 and is connected to the first bevel gear 106, and the other clamping column of the first clamping frame 103 is inserted into the round hole of the semi-circular ring 102.

[0052] Specifically, when in use, manually connect the slots 104 and plugs 105 of two adjacent HPVC power pipes 100. Then, rotate the first card holder 103 to drive the first bevel gear 106, which in turn drives the second bevel gear 107 to rotate. The rotation of the second bevel gear 107 drives the transmission shaft 108 to rotate. The transmission shaft 108 drives the camming wheel 115 to rotate, which in turn drives the drive post 1125 of the film-breaking mechanism 112, and then drives the rotating ring 1121 to rotate. The rotating ring 1121 drives the sliding plate 1123 to work. After rotation, move the movable semi-circular ring 102 close to the first card holder 103, and then insert the short rods on both sides of the first card holder 103 into the grooves of the semi-circular ring 102, so as to fix the semi-circular ring 102 and the first card holder 103, then fix the first bevel gear 106, and fix the film-breaking mechanism 112, preventing the film-breaking mechanism 112 from driving the sliding plate 1123 to move and driving the pointed cone 1128 to move and scratch the cable when vibrating.

[0053] A drain hole 110 is provided on the slot 104 (refer to Figure 6 ), and a one-way valve is provided in the drain hole 110. When the plug 105 is inserted into the slot 104, since the plug 105 drives the first waterproof film 114, the water inside the slot 104 is discharged from the drain hole 110.

[0054] Refer to Figure 14 、 17 And 18, a bracket structure, characterized in that it includes a jamming mechanism 220, fixing mechanisms 210 are respectively connected to both sides of the jamming mechanism 220, a pipe hoop mechanism 230 is installed on the jamming mechanism 220, the pipe hoop mechanism 230 includes a first clamp 231 and a second clamp 232, a second limiting plate 233 is arranged on the lower surface of the second clamp 232, the second limiting plate 233 is slidably installed on the jamming mechanism 220, a first limiting rod 234 is arranged below the second clamp 232, the first limiting rod 234 is inserted into the hole of the first limiting plate 214, a third card holder 235 is installed on the side of the second clamp 232, the third card holder 235 passes through the second clamp 232 and is connected to the protruding plate of the first clamp 231; and the above-mentioned HPVC power pipe 100 is installed between the first clamp 231 and the second clamp 232 (refer to Figure 1 And 2 ).

[0055] Refer to Figure 15, the jamming mechanism 220 plays a connecting role. Two fixing mechanisms 210 are respectively installed on both sides of the jamming mechanism 220, and the two fixing mechanisms 210 are respectively fixedly connected to the seabed ground. The pipe hoop mechanism 230 is slidably installed in the jamming mechanism 220, and the pipe hoop mechanism 230 is used to fix the HPVC power pipe 100. The fixing mechanism 210 includes a third limiting plate 212, a fixing connecting plate 211 is slidably installed on the third limiting plate 212, and a plug rod 213 is arranged at the lower end of the fixing connecting plate 211; a fourth clamping frame 215 is slidably installed on the side of the third limiting plate 212; a first limiting plate 214 is arranged on one side of the third limiting plate 212 close to the jamming mechanism 220, and the first limiting plate 214 is slidably installed in the jamming mechanism 220. The first limiting plate 214 is slidably installed in the chute of the chassis 221, the fixing connecting plate 211 is slidably installed on the side of the third limiting plate 212, and the plug rod 213 is used to fix the bracket mechanism 200; a plurality of grooves are arranged on the side of the fixing connecting plate 211. When the fourth clamping frame 215 passes through the grooves on the side of the fixing connecting plate 211, it is used to fix the fixing connecting plate 211, which is convenient for adjusting the positions of the fixing connecting plate 211 and the plug rod 213.

[0056] Reference Figure 15 , the jamming mechanism 220 includes a chassis 221, a U-shaped plate 224 is arranged on the upper surface of the chassis 221, and two symmetrical Z-shaped rods 222 are slidably installed inside the U-shaped plate 224 (Reference Figure 16 ), a gear 223 is arranged between the inner racks of the Z-shaped rods 222, and the gear 223 meshes with the two Z-shaped rods 222 respectively; a second clamping frame 225 is slidably installed on the U-shaped plate 224, and the second clamping frame 225 passes through the U-shaped plate 224 and is inserted into the gear 223. By rotating the second clamping frame 225, the gear 223 is driven to rotate, and then the two Z-shaped rods 222 are driven to move, so that the other ends of the Z-shaped rods 222 are inserted into the card slots on the second limiting plate 233, thereby realizing the limitation of the second pipe hoop 232, the first pipe hoop 231 and the HPVC power pipe 100. At the same time, the first limiting rod 234 is slidably installed in the hole of the first limiting plate 214, thereby performing secondary limitation on the first limiting plate 214. Sealing strips 236 are arranged on the inner sides of the first pipe hoop 231 and the second pipe hoop 232, and the sealing strips 236 are installed in the sealing grooves 111 to seal the connected HPVC power pipe 100 and achieve re-sealing.

[0057] Working principle: This invention is used underwater. First, place the jamming mechanism 220 on the seabed. Then, slidably install the fixed connecting plate 211 of the fixing mechanism 210 in the third limiting plate 212. According to the installation height, insert the fourth clamping frame 215 into the end face of the third limiting plate 212 to fix the fixed connecting plate 211 and the inserting rod 213, and insert the inserting rod 213 into the seabed. Then, insert the first limiting plate 214 into the chassis 221 as required. Next, insert the second limiting plate 233 of the second clamp 232 of the pipe hoop mechanism 230 into the groove of the chassis 221, adjust the second clamp 232 to the appropriate position, and then manually rotate the second clamping frame 225 to drive the gear 223 to drive the two Z-shaped rods 222 to insert into the holes on the two second limiting plates 233 respectively. At the same time, the first limiting rod 234 is inserted into the hole of the first limiting plate 214 to achieve secondary fixation of the first limiting plate 214.

[0058] Deliver the HPVC power pipe 100 to the designated water surface by ship. Then, manually pull out the sealing plug 117 to allow water to enter the space between the outer pipe 101, the inner pipe 109, and the two groups of sealing partitions 116, so that the HPVC power pipe 100 sinks to the bottom of the water. Plug the sealing plug 117, and dock the slots 104 and plugs 105 of two adjacent HPVC power pipes 100. At this time, the water in the circular pipe of the slot 104 (the space from the second waterproof membrane 1127 to the end of the slot 104) is squeezed by the first waterproof membrane 114 of the plug 105, and the water is squeezed out from the one-way valve in the drain hole 110 until the slot 104 and the plug 105 are completely sealed and connected.

[0059] Then, manually rotate the first clamping frame 103 by the worker, so that the first clamping frame 103 drives the first bevel gear 106 to drive the second bevel gear 107 to rotate. The rotation of the second bevel gear 107 drives the transmission shaft 108 and then drives the caster wheel 115 to rotate. The rotation of the caster wheel 115 drives a number of driving columns 1125 to drive the rotating ring 1121 to rotate. In the initial position, the ends of the five sliding plates 1123 with pointed cones 1128 gather at the center of the second waterproof membrane 1127, and the sliding rods of the sliding plates 1123 are located at the shallow groove end of the limiting groove 1124 close to the fixed ring 1122. At this time, the pointed cone 1128 does not contact the second waterproof membrane 1127. When the driving mechanism drives the rotating ring 1121 to rotate, as the shallow groove of the limiting groove 1124 reaches the deep groove, the pointed cone 1128 of the sliding plate 1123 moves towards the second waterproof membrane 1127 under the pull of the tension spring 1126 and penetrates the second waterproof membrane 1127, and then cuts open the second waterproof membrane 1127 under the drive of the rotating ring 1121, as Figure 11 shown. Figure 11The curve on the second waterproof film 1127 is the moving curve of the sharp cone 1128. At the same time, the sharp cone 1128 close to the plug 105 cuts open the second waterproof film 1127 and the first waterproof film 114 simultaneously. At this time, the water remaining between the slot 104 and the plug 105 is adsorbed by the carbon ring 113.

[0060] Then, the connected HPVC power pipe 100 is placed on the second clamp 232, so that the sealing strip 236 is snapped into the sealing groove 111. Then, the first clamp 231 is installed on the second clamp 232. At the same time, the sealing strip 236 of the first clamp 231 is snapped into the sealing groove 111. Then, the third bracket 235 is inserted into the groove on the side of the second clamp 232, and then the plate (as Figure 18 shown) protruding from the first clamp 231 is clamped, realizing the clamped installation. Then, by pushing the cable, the cable is moved between adjacent HPVC power pipes 100, thus completing the laying of the cable.
