Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a connection component for a glass fiber braided cable protective sleeve conduit. Background Technology

[0002] Fiberglass braided cable protection conduit, also known as fiber braided pultruded cable protection conduit, BWFRP cable protection conduit, BWFRP fiber braided pultruded tube, BWFRP braided pultruded tube, BWFRP fiber braided tube, fiber braided tube, braided pultruded tube, braided spiral pultruded tube, etc.

[0003] The pipe has a three-layer structure: the inner and outer layers are cross-braided, and the middle layer is a composite layer of circumferential and longitudinal braids. The inner and outer braided layers with different braiding angles, together with the longitudinal and circumferential composite middle layer, constitute this unique composite material product, which greatly improves the ring stiffness of the BWFRP pipe and has better impact resistance and toughness.

[0004] When installing fiberglass braided cable protection conduits, they need to be placed on a pipe support, and then two fiberglass braided cable protection conduits are connected together using components such as straight connectors and sealing rings. The sealing ring is fitted onto the outside of the protection conduit. Since the sealing ring is used to fill gaps, there is a lot of resistance when inserting it. Workers need to apply lubricating substances such as petroleum jelly, but it is not always applied evenly, and there is still a lot of resistance during installation, making the installation operation very time-consuming and laborious. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a connection assembly for glass fiber braided cable protective sleeve conduit, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connection assembly for a glass fiber braided cable protective sleeve conduit, comprising a connecting cylinder and a protective sleeve body, wherein the connecting cylinder comprises a first inner braided layer, and a first circumferential composite layer is sleeved on the outside of the first inner braided layer, a first outer braided layer is sleeved on the outside of the first circumferential composite layer, and a coarsening layer is provided on the outside of the first outer braided layer, and a cold shrink sleeve is connected to the outside of the coarsening layer through an adhesive layer, and a support layer is connected to the inner ring of the cold shrink sleeve.

[0007] By adopting the above technical solution, during installation, it is only necessary to insert the main body of the protective sleeve into the inside of the docking cylinder, and then remove the support layer so that the inner ring of the cold shrink sleeve loses its support and begins to shrink to tightly hug the docking cylinder and the main body of the protective sleeve to form a seal. The operation is simple, convenient, time-saving and labor-saving. During the production process, it is only necessary to roughen the surface of the joint to form a roughened layer and apply silicone glue. Then, the cold shrink sleeve is put on the outside of the joint and part of the support layer is removed, so that the end of the cold shrink sleeve outside the joint shrinks and sticks tightly to the joint. After the silicone glue solidifies, an adhesive layer is formed to fix the cold shrink sleeve, avoiding the cold shrink sleeve from falling off due to bumps, vibrations and other reasons during transportation and storage.

[0008] Furthermore, the adhesive layer is silicone adhesive.

[0009] By adopting the above technical solution, the adhesive layer formed by the silicone adhesive has excellent bonding strength to the cold shrink tubing, and the bonding strength with the connecting cylinder is increased by setting the roughening layer.

[0010] Furthermore, the length of the support layer is less than the length of the cold shrink tubing, and the cold shrink tubing is fixedly connected to the first outer braided layer through an adhesive layer and a roughening layer.

[0011] By adopting the above technical solution, after the silicone adhesive solidifies, an adhesive layer is formed to fix the cold shrink tubing. The coarse layer during this process increases the bonding strength and prevents the cold shrink tubing from falling off due to bumps, vibrations, etc. during transportation and storage. Workers can cut off the pulled-out support layer to prevent long, discarded support layers from scattering and getting caught or stuck during transportation and storage, thus preventing the support layer from being pulled off and the cold shrink tubing from losing support and starting to shrink during transportation and storage.

[0012] Furthermore, there are two of each of the adhesive layer, cold shrink tubing, and support layer, and the two cold shrink tubing and support layers are mirror images of each other.

[0013] By adopting the above technical solution, the two cold shrink tubings are fixed independently, reducing the difficulty of fixing the cold shrink tubings to the docking cylinder and facilitating the extraction of the support layer in the area between the middle and docking cylinders.

[0014] Furthermore, the protective sleeve body is provided in two parts, and the protective sleeve body includes a second inner braided layer, a second circumferential composite layer is sleeved on the outside of the second inner braided layer, and a second outer braided layer is sleeved on the outside of the second circumferential composite layer.

[0015] By adopting the above technical solutions, the ring stiffness of the protective sleeve body has been greatly improved, resulting in better impact resistance and toughness.

[0016] Furthermore, the outer diameter of the second outer braided layer is adapted to the inner diameter of the first inner braided layer.

[0017] By adopting the above technical solution, during installation, the staff inserts the two protective sleeve bodies into the two ends of the docking cylinder respectively, thereby completing the docking of the protective sleeve bodies.

[0018] Furthermore, both the docking cylinder and the protective sleeve body are made of fiberglass material.

[0019] By adopting the above technical solutions, the product features high ring stiffness, resistance to high and low temperatures, high electrical insulation, high tensile strength, strong flame retardancy, corrosion and water resistance, excellent thermal conductivity, smooth inner wall, easy transportation and installation, and safety and environmental protection.

[0020] Furthermore, the inner ring of the first inner braided layer is connected to a sealing ring.

[0021] By adopting the above technical solution, after inserting the two protective sleeve bodies into the docking cylinder, the gap between the two docking sleeves is filled by the sealing ring, thereby further improving the sealing performance.

[0022] Furthermore, the outer ring of the cold shrink tubing is wrapped with adhesive tape.

[0023] By adopting the above technical solution, workers can choose to wrap a layer of tape around the outer ring of the cold shrink tubing and press it tightly to further fix the cold shrink tubing, ensuring that the cold shrink tubing is tightly fitted to the main body of the protective tubing, and can also play a role in supplementing the sealing performance, enhancing wear resistance, and enhancing impact resistance.

[0024] In summary, the present invention has the following main advantages:

[0025] This invention, through the design of a roughening layer, an adhesive layer, a cold-shrink tubing, and a support layer, allows for simple and convenient installation. During installation, the protective tubing body is inserted into the connecting cylinder, and then the support layer is removed, causing the inner ring of the cold-shrink tubing to shrink and tightly seal the connecting cylinder and the protective tubing body. This process is simple, convenient, time-saving, and labor-saving. During production, only a roughening layer is applied to the surface of the connecting joint, followed by the application of silicone adhesive. The cold-shrink tubing is then placed over the connecting joint, and a portion of the support layer is removed, allowing the end of the cold-shrink tubing outside the connecting joint to shrink and adhere tightly. Once the silicone adhesive has solidified, an adhesive layer is formed, securing the cold-shrink tubing and preventing it from detaching due to bumps or vibrations during transportation and storage. This further simplifies the operation and saves effort. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A connection assembly for fiberglass braided cable protective sheath conduit, such as Figures 1-5 As shown, the device includes a docking cylinder 1 and a protective sleeve body 5. The docking cylinder 1 includes a first inner braided layer 101, a first circumferential composite layer 102 sleeved on the outside of the first inner braided layer 101, a first outer braided layer 103 sleeved on the outside of the first circumferential composite layer 102, a roughened layer 104 disposed on the outside of the first outer braided layer 103, and a cold shrink sleeve 3 connected to the outside of the roughened layer 104 through an adhesive layer 2. The adhesive layer 2 is silicone adhesive. The cold shrink sleeve 3 is fixedly connected to the first outer braided layer 103 through the adhesive layer 2 and the roughened layer 104. A support layer 4 is connected to the inner ring of the cold shrink sleeve 3. The length of the support layer 4 is less than the length of the cold shrink sleeve 3. There are two of each of the adhesive layer 2, the cold shrink sleeve 3, and the support layer 4. The two cold shrink sleeves 3 and the support layer 4 are mirror images of each other. The operator inserts the protective sleeve body 5 into the docking cylinder 1 and then removes the support layer 4, causing the inner ring of the cold shrink sleeve 3 to lose support and begin to shrink to tightly hug the docking cylinder 1 and the protective sleeve body 5 to form a seal.

[0036] See Figure 4 and Figure 5In the above embodiment, there are two protective sleeve bodies 5. The protective sleeve body 5 includes a second inner braided layer 501, a second circumferential composite layer 502 sleeved on the outside of the second inner braided layer 501, and a second outer braided layer 503 sleeved on the outside of the second circumferential composite layer 502. The outer diameter of the second outer braided layer 503 is adapted to the inner diameter of the first inner braided layer 101. Both the docking cylinder 1 and the protective sleeve body 5 are made of fiberglass material. The inner ring of the first inner braided layer 101 is connected to a sealing ring 6. During installation, the operator first puts the sealing ring 6 into the docking cylinder 1, and then the operator inserts the protective sleeve body 5 into the docking cylinder 1.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are now used to improve performance.

[0039] See Figure 4 and Figure 5 In the above embodiment, the outer ring of the cold shrink tubing 3 is wrapped with tape 7. The operator can choose to wrap a layer of tape 7 around the outer ring of the cold shrink tubing 3 to press it tightly and further fix the cold shrink tubing 3, so as to ensure that the cold shrink tubing 3 is tightly fitted with the protective tubing body 5, and can also play a role in supplementing the sealing, strengthening wear resistance, and strengthening impact resistance.

[0040] The implementation principle of this utility model is as follows: First, during the production process, the worker only needs to roughen the surface of the joint to form a roughening layer 104 and apply silicone glue. Then, the worker puts the cold shrink sleeve 3 on the outside of the joint and removes part of the support layer 4, so that the end of the cold shrink sleeve 3 outside the joint shrinks and sticks tightly to the joint. After the silicone glue solidifies, an adhesive layer 2 is formed to fix the cold shrink sleeve 3. During this process, the roughening layer 104 increases the adhesive strength and prevents the cold shrink sleeve 3 from falling off due to bumps, vibrations, etc. during transportation and storage. The worker can cut off the part of the support layer 4 that has been pulled out to prevent the long waste support layer 4 from scattering outside and getting hooked or stuck during transportation and storage, which would cause the support layer 4 to be pulled out, thereby preventing the cold shrink sleeve 3 from losing support and starting to shrink during transportation and storage. The installation method of the other cold shrink sleeve 3 is the same.

[0041] During installation, the workers first place the sealing ring 6 into the docking cylinder 1, then insert the protective sleeve body 5 into the docking cylinder 1, and then remove the support layer 4 so that the inner ring of the cold shrink sleeve 3 loses support and begins to shrink to tightly hug the docking cylinder 1 and the protective sleeve body 5 to form a seal. At this time, the workers can choose to wrap a layer of tape 7 around the outer ring of the cold shrink sleeve 3 to press it tight and further fix the cold shrink sleeve 3, ensuring that the cold shrink sleeve 3 and the protective sleeve body 5 fit tightly together, which can also play a role in supplementing the sealing performance, strengthening wear resistance, and strengthening impact resistance.
