Description

Technical Field

[0001] This utility model relates to the field of power cable conduit technology, specifically a chlorinated polyvinyl chloride (CPVC) conduit for buried high-voltage power cables. Background Technology

[0002] Cable conduits, also known as protective conduits or ducts, are pipes used in electrical installations to protect wires and cables, allowing for their insertion and replacement. Cable conduits are a new type of conduit material widely used in power engineering. CPVC is a promising new engineering plastic. The resin is obtained by chlorinating and modifying polyvinyl chloride (PVC) resin, and is a new type of engineering plastic. The product is a white or pale yellow, tasteless, odorless, and non-toxic loose granules or powder. After chlorination, the irregularity of the molecular bonds in PVC resin increases, as does its polarity, leading to increased solubility and chemical stability, thereby improving the material's resistance to heat, acids, alkalis, salts, and oxidants.

[0003] To ensure the durability of power cables, they are generally installed underground. During installation, protective sleeves are usually installed on the surface of the power cables to make them more durable. Currently, common power cable conduits on the market often require splicing due to the long overall length of the cables. When splicing cable conduits, one cable conduit is usually inserted into the inside of another to complete the splicing. If the cable conduit is subjected to significant external force, the joint may detach, further affecting the protective function of the cable conduit.

[0004] Therefore, we propose a chlorinated polyvinyl chloride (CPVC) pipe sleeve for buried high-voltage power cables. Summary of the Invention

[0005] The purpose of this utility model is to provide a chlorinated polyvinyl chloride (CPVC) pipe sleeve for buried high-voltage power cables to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chlorinated polyvinyl chloride (CPVC) pipe sleeve for buried high-voltage power cables, comprising a base plate, on which a first pipe sleeve and a second pipe sleeve are respectively placed from left to right above the base plate; a reinforcing component, which is installed above the base plate and is used to reinforce the joint between the first and second pipe sleeves; and an auxiliary component, which is installed in the middle above the base plate and is used to reinforce the dead corners at the joint of the base plate.

[0007] Preferably, the reinforcement component includes mounting blocks, which are in two sets. A reinforcement ring is rotatably connected between the adjacent surfaces of the two sets of mounting blocks. A uniformly distributed first extrusion rod is fixedly installed between the adjacent surfaces of the two reinforcement rings. A reinforcement sleeve is fitted onto the outer surface of the joint between the first sleeve and the second sleeve. The size of the first extrusion rod is adapted to the size of the reinforcement sleeve.

[0008] Preferably, a fixing plate is fixedly installed on the upper end of both reinforcing rings.

[0009] Preferably, the upper surface of the base plate has four mounting holes arranged in a rectangular pattern.

[0010] Preferably, both ends of the first and second sleeves are chamfered, and the chamfer at the joint of the first and second sleeves is shown in the figure.

[0011] Preferably, the auxiliary component includes a reinforcing frame placed in the middle of the upper surface of the base plate. The bottom surface of the reinforcing frame has several evenly distributed guide grooves. Several guide rods are fixedly installed on the upper surface of the base plate. Each guide rod is engaged with its corresponding guide groove. Multiple elastic steel plates are installed between the bottom surface of the reinforcing frame and the upper surface of the base plate.

[0012] Preferably, the upper surface of the reinforcing frame is provided with a slot, and several evenly distributed second extrusion rods are fixedly installed at the slot on the upper surface of the reinforcing frame. The size of the second extrusion rods is adapted to the size of the reinforcing sleeve.

[0013] Preferably, the reinforcing sleeve is capable of elastic deformation.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When laying power cables, firstly, place the first and second sleeves onto the surface of the cable. Then, place the base plate in the appropriate position and fix it with fasteners through the mounting holes. Next, place the reinforcing sleeve onto the surface of the first sleeve. Then, the second sleeve and the first sleeve can be spliced ​​together by cutting an angle. Next, move the center point of the reinforcing sleeve to the splice point of the first and second sleeves. Then, close the two reinforcing rings and install them with screws through the fixing plate to firmly fix the two reinforcing rings together. Then, the first compression rod will compress the reinforcing sleeve, so that the reinforcing sleeve is firmly attached to the surface of the first and second sleeves, achieving the function of secondary reinforcement of the splice point of the first and second sleeves.

[0016] By setting up reinforcement components, the joint between the first and second sleeves can be further secured, effectively preventing cracking of the joint due to external forces after prolonged use.

[0017] 2. When the reinforcing ring is not in the closed state, the reinforcing frame will be in an upward state under the action of the elastic steel plate. When the reinforcing sleeve is placed on the surface of the second extrusion rod, the closing of the reinforcing ring will push the reinforcing sleeve downward as a whole. At this time, the reinforcing frame will apply a reaction force to the reinforcing sleeve through the elastic steel plate. At this time, the second extrusion rod can extrude force on the reinforcing sleeve. When the reinforcing ring is fully closed, the reinforcing frame will be in a downward state. The elasticity of the elastic steel plate will still apply force to the reinforcing sleeve, thereby achieving the effect of reinforcing the bottom ends of the first and second sleeves.

[0018] By setting auxiliary components, the reinforcement dead corners of the first and second sleeves after the reinforcement components are reinforced can be fixed again, which can further make the first and second sleeves more solid after splicing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] Example 1: A buried high-voltage power cable chlorinated polyvinyl chloride (CPVC) pipe sleeve includes a base plate 3, a first pipe sleeve 4 and a second pipe sleeve 5 placed on the top of the base plate 3 from left to right, a reinforcing component 1 installed on the top of the base plate 3, the reinforcing component 1 being used to reinforce the joint of the first pipe sleeve 4 and the second pipe sleeve 5, and an auxiliary component 2 installed in the middle of the top of the base plate 3, the auxiliary component 2 being used to reinforce the dead corners at the joint of the base plate 3.

[0027] The reinforcement component 1 includes a mounting block 6, which has two sets. A reinforcement ring 7 is rotatably connected between the two sets of mounting blocks 6 on their adjacent sides. A uniformly distributed first extrusion rod 8 is fixedly installed between the two adjacent sides of the two reinforcement rings 7. A reinforcement sleeve 10 is fitted onto the outer surface of the joint between the first sleeve 4 and the second sleeve 5. The size of the first extrusion rod 8 is adapted to the size of the reinforcement sleeve 10.

[0028] A fixing plate 9 is fixedly installed on the upper end of each of the two reinforcing rings 7, which is used to fix the position of the reinforcing rings 7 with screws.

[0029] The upper surface of the base plate 3 has four rectangular mounting holes 11 for fixing the base plate 3 to the ground.

[0030] Both ends of the first sleeve 4 and the second sleeve 5 are chamfered. The chamfer at the joint of the first sleeve 4 and the second sleeve 5 is shown in the figure. This allows for a smaller gap after the first sleeve 4 and the second sleeve 5 are joined together.

[0031] When laying power cables, firstly, the first sleeve 4 and the second sleeve 5 are respectively placed on the surface of the cable. Then, the base plate 3 is placed in a suitable position and fixed with fasteners through the mounting holes 11. Next, the reinforcing sleeve 10 is placed on the surface of the first sleeve 4. Then, the second sleeve 5 and the first sleeve 4 are spliced ​​together by opening an angle. Next, the center point of the reinforcing sleeve 10 is moved to the splice of the first sleeve 4 and the second sleeve 5. Then, the two reinforcing rings 7 are closed and then installed with screws through the fixing plate 9 to achieve the purpose of firmly fixing the two reinforcing rings 7 together. Then, the first compression rod 8 will compress the reinforcing sleeve 10, so that the reinforcing sleeve 10 is firmly attached to the surface of the first sleeve 4 and the second sleeve 5, achieving the function of secondary reinforcement of the splice of the first sleeve 4 and the second sleeve 5.

[0032] By setting the reinforcement component 1, the splicing joint of the first sleeve 4 and the second sleeve 5 can be further fixed, which can effectively prevent the splicing joint of the first sleeve 4 and the second sleeve 5 from cracking due to external force after long-term use.

[0033] In embodiment 2, auxiliary component 2 includes a reinforcing frame 12, which is placed in the middle of the upper surface of the base plate 3. The bottom surface of the reinforcing frame 12 has several evenly distributed guide grooves 14. Several guide rods 15 are fixedly installed on the upper surface of the base plate 3. Each guide rod 15 is engaged with its corresponding guide groove 14. Multiple elastic steel plates 16 are installed between the bottom surface of the reinforcing frame 12 and the upper surface of the base plate 3.

[0034] The upper surface of the reinforcing frame 12 is provided with a slot, and several evenly distributed second extrusion rods 13 are fixedly installed at the slot on the upper surface of the reinforcing frame 12. The size of the second extrusion rods 13 is adapted to the size of the reinforcing sleeve 10.

[0035] The reinforcing sleeve 10 can undergo elastic deformation, which allows the first extrusion rod 8 and the second extrusion rod 13 to deform the reinforcing sleeve 10 when they are extruded.

[0036] When the reinforcing ring 7 is not in the closed state, the reinforcing frame 12 will be in an upward state under the action of the elastic steel plate 16. When the reinforcing sleeve 10 is placed on the surface of the second extrusion rod 13, the reinforcing ring 7 will push the reinforcing sleeve 10 downward as a whole. At this time, the reinforcing frame 12 will exert a reaction force on the reinforcing sleeve 10 through the elastic steel plate 16. At this time, the second extrusion rod 13 can extrude force on the reinforcing sleeve 10. When the reinforcing ring 7 is fully closed, the reinforcing frame 12 will be in a downward state. The elastic steel plate 16 will still exert a force on the reinforcing sleeve 10, so as to reinforce the bottom end of the first sleeve 4 and the second sleeve 5.

[0037] By setting auxiliary component 2, the dead corners of the first sleeve 4 and the second sleeve 5 after the reinforcement component 1 are reinforced can be fixed again, and the first sleeve 4 and the second sleeve 5 can be made more solid after splicing.
