Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable equipment, in particular to a plugging device for a power cable protection sleeve. BACKGROUND

[0002] When a cable is changed from overhead to underground, it needs to be threaded through a vertical protection sleeve, and the diameter of the protection sleeve is generally 1.5 times the diameter of the cable. Therefore, after the cable is threaded into the protection sleeve, a gap will be generated between the cable and the protection sleeve. In the related art, in order to prevent rainwater, sundries and small animals from entering the cable tunnel through the gap between the cable and the protection sleeve, fireclay is filled at the gap between the cable and the protection sleeve. However, the fireclay is affected by temperature changes and wind, rain and frost in the outdoor environment and is prone to aging and falling off, and the sealing effect is difficult to last. For example, in summer, the surface temperature of the cable can reach 70-80℃, and the fireclay softens at 55℃. At this time, the fireclay loses stability and sinks, and gradually falls off under the action of gravity, thereby losing the plugging effect. SUMMARY

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1-6 As shown, the sealing device for the power cable protective sleeve according to the embodiment of the present invention includes: a first annular member 1 , a second annular member 2 and a mounting member 3 .

[0036] The axial direction of the first annular member 1 and the axial direction of the second annular member 2 are parallel to each other, and the first annular member 1 and the second annular member 2 are parallel to each other along the axial direction of the first annular member 1 (such as Figure 1 The first annular member 1 and the second annular member 2 are arranged in sequence (in the up and down direction), at least one of the first annular member 1 and the second annular member 2 is divided into a plurality of fastening parts, and the plurality of fastening parts are connected in sequence along the circumference of at least one of the first annular member 1 and the second annular member 2. The inner circumference of the first annular member 1 is surrounded by a first through-hole 11, and the inner circumference of the second annular member 2 is surrounded by a second through-hole 21. The first through-hole 11 and the second through-hole 21 are relative to and connected with each other in the axial direction of the first annular member 1. The first annular member 1 is used to be sleeved on the outer circumference of the cable 100, and the second annular member 2 is used to be sleeved on the protective sleeve 200. The protective sleeve 200 is sleeved on the outer circumference of the cable 100.

[0037] It can be understood that the first ring-shaped member 1 can be divided into multiple fastening parts; or, the second ring-shaped member 2 can be divided into multiple fastening parts; or, both the first ring-shaped member 1 and the second ring-shaped member 2 can be divided into multiple fastening parts, that is, the first ring-shaped member 1 can be divided into multiple first fastening parts 12, and the second ring-shaped member 2 can be divided into multiple second fastening parts 22.

[0038] The mounting member 3 is connected between the first annular member 1 and the second annular member 2. The mounting member 3 is provided with a third through-hole 31 which passes through the mounting member 3 along the axial direction of the first annular member 1. The third through-hole 31 is respectively opposite to the first through-hole 11 and the second through-hole 21 and is connected to each other, so that the cable 100 passes through the first through-hole 11, the third through-hole 31 and the second through-hole 21 in sequence.

[0039] Specifically, if Figure 1 As shown, the first annular member 1, the mounting member 3 and the second annular member 2 are connected from top to bottom, and the first through-hole 11, the third through-hole 31 and the second through-hole 21 are connected at one time, so that the cable 100 can be inserted into the protective sleeve 200 through the first through-hole 11 and the third through-hole 31.

[0040] It is understandable that, because the radial dimension of the cable 100 is smaller than the inner diameter of the protective sleeve 200, and after the first annular member 1 is sleeved on the outer circumference of the cable 100 and the second annular member 2 is sleeved on the outer circumference of the protective sleeve 200, after the cable 100 is inserted into the protective sleeve 200, a gap exists between the outer circumference of the cable 100 and the inner circumference of the protective sleeve 200. Therefore, the mounting member 3 connected between the first annular member 1 and the second annular member 2 can be used to connect the first annular member 1 and the second annular member 2, and can also block the gap between the cable 100 and the protective sleeve 200.

[0041] It should be noted that the mounting member 3 can be connected to the first annular member 1 and the second annular member 2 via a connecting member, such as a screw, a bolt, or the like. Alternatively, the connection can be made via a thread.

[0042] In other words, the sealing device for a power cable protective sleeve according to an embodiment of the present invention can utilize the first annular member 1 to connect to the cable 100. That is, the cable 100 passes through the first annular member 1 through the first perforation 11, so that the first annular member 1 is sleeved on the outer circumference of the cable 100. The second annular member 2 is connected to the port of the protective sleeve 200. That is, the second annular member 2 is sleeved on the port of the protective sleeve 200. The first annular member 1 and the second annular member 2 are then connected using the mounting member 3. This connects the first annular member 1 and the second annular member 2 and the mounting member 3 is used to seal the port of the protective sleeve 200, thereby preventing rainwater, debris, small animals, etc. from entering the protective sleeve 200 through the gap between the cable 100 and the protective sleeve 200.

[0043] In addition, the first ring-shaped member 1, the mounting member 3 and the second ring-shaped member 2 are sequentially connected, so that the cable 100 and the protective sleeve 200 are stably connected, the shaking of the cable 100 is avoided, and the abrasion between the cable 100 and the protective sleeve 200 is reduced.

[0044] Embodiment one:

[0045] As shown in Figure 1 , the first ring-shaped member 1 is divided into a plurality of first fastening parts 12, and the second ring-shaped member 2 is integrally formed. Preferably, the mounting member 3 is also an integrally formed ring-shaped member, and the inner circumferential surface of the mounting member 3 surrounds the third through hole 31.

[0046] As shown in Figure 1 , the first ring-shaped member 1 includes a plurality of first fastening parts 12, one of the two adjacent first fastening parts 12 is provided with a first protrusion 13, and the other of the two adjacent first fastening parts 12 is provided with a first groove 14 matched with the first protrusion 13. The first protrusion 13 is arranged on one of the two adjacent first fastening parts 12 and adjacent to one side of the other of the two adjacent first fastening parts 12.

[0047] It can be understood that the first ring-shaped member 1 can include at least two first fastening parts 12, for example, Figure 1 , the first ring-shaped member 1 is divided into two first fastening parts 12, a first protrusion 13 is arranged on the first fastening part 12 on the right side, and a first groove 14 matched with the first protrusion 13 is arranged on the first fastening part 12 on the left side. Therefore, when the first ring-shaped member 1 is sleeved on the cable 100, the first protrusion 13 can be matched in the first groove 14 to prevent the two first fastening parts 12 from moving relative to each other in the vertical direction.

[0048] Specifically, as shown in Figure 1 , the first ring-shaped member 1 can be divided into two first fastening parts 12 by a vertical (i.e. upward and downward) cross section, and each first fastening part 12 includes a vertical first connecting surface 16. A first protrusion 13 is arranged on the first connecting surface 16 on the right side, and a first groove 14 is arranged on the first connecting surface 16 on the left side.

[0049] That is, during installation, the second ring-shaped member 2 can be sleeved on the port of the protective sleeve 200, the mounting member 3 is connected with the second ring-shaped member 2 through the connecting member, the cable 100 is inserted into the protective sleeve 200 through the third through hole 31 until a predetermined position, then the two first fastening parts 12 are respectively sleeved on the outer circumferential surface of the cable 100 from both sides of the cable 100, the first protrusion 13 and the first groove 14 are matched, and finally the first ring-shaped member 1 is connected with the mounting member 3 to complete the installation of the plugging device for the protective sleeve of the power cable according to the embodiment of the present application.

[0050] In other words, during installation, since the length of the cable 100 inserted into the protective sleeve 200 needs to be determined according to the actual working conditions, the first annular member 1 is divided into a plurality of first fastening parts 12. Before the sealing device for the power cable protective sleeve of the embodiment of the present invention is completely installed, relative movement can occur between the cable 100 and the protective sleeve 200, that is, the length of the cable 100 inserted into the protective sleeve 200 can be changed according to the change of the actual working conditions. Therefore, the sealing device for the power cable protective sleeve of the embodiment of the present invention is more practical and easier to install.

[0051] Example 2:

[0052] On the basis of Example 1, the second annular member 2 is divided into a plurality of second fastening portions 22, one of two adjacent second fastening portions 22 is provided with a second protrusion 23, the other of the two adjacent second fastening portions 22 is provided with a second groove 24 matching the second protrusion 23, and the second protrusion 23 is provided on a side of one of the two adjacent second fastening portions 22 adjacent to the other of the two adjacent first fastening portions 12.

[0053] It is understandable that the second annular member 2 may include at least two second fastening portions 22, such as Figure 2 and Figure 3 As shown, taking the second ring member 2 being divided into two second fastening parts 22 as an example, the second fastening part 22 located on the right is provided with a second protrusion 23, and the second fastening part 22 located on the left is provided with a second groove 24 matching the second protrusion 23. Therefore, when the second ring member 2 is sleeved on the port of the protective sleeve 200, the second protrusion 23 can be engaged with the second groove 24 to prevent the two second fastening parts 22 from moving relative to each other in the up and down directions.

[0054] Specifically, if Figure 2 and Figure 3 As shown, the second ring member 2 can be divided into two second fastening parts 22 through a vertical (i.e., up and down) cross section, and each second fastening part 22 includes a vertical second connecting surface 27, and a second protrusion 23 is provided on the second connecting surface 27 on the right, and a second groove 24 is provided on the second connecting surface 27 on the left.

[0055] That is to say, if Figure 2 and Figure 3As shown, during installation, the two second fastening parts 22 can be put on the port of the protective sleeve 200 from both sides of the protective sleeve 200, so that the second protrusion 23 is matched with the second groove 24, and the mounting part 3 is connected to the second ring part 2 through the connecting part, so that the second ring part 2 is fixedly connected to the protective sleeve 200. The cable 100 is inserted into the protective sleeve 200 through the third through-hole 31 until it reaches the preset position, and then the two first fastening parts 12 are respectively put on the outer circumference of the cable 100 from both sides of the cable 100, and the first protrusion 13 is matched with the first groove 14. Finally, the first ring part 1 is connected to the mounting part 3 to complete the installation of the sealing device for the power cable protective sleeve according to the embodiment of the present invention.

[0056] It should be noted that during installation, the mounting member 3 needs to be put on the cable 100 first, that is, when the cable 100 is inserted into the protective sleeve 200, the mounting member 3 is put on the outer peripheral surface of the cable 100 and adjacent to the port of the protective sleeve 200, until the cable 100 is inserted into the preset position, and then the second ring member 2 and the first ring member 1 are respectively put on the protective sleeve 200 and the cable 100, and finally the mounting member 3 is used to connect the first ring member 1 and the second ring member 2.

[0057] Example 3:

[0058] On the basis of the second embodiment, similarly, the mounting member 3 is divided into a plurality of third fastening portions 32 , and the plurality of third fastening portions 32 are sequentially connected along the circumference of the mounting member 3 .

[0059] That is to say, if Figure 3 and Figure 4 As shown, the first ring member 1 can be divided into multiple first fastening parts 12, the second ring member 2 can be divided into multiple second fastening parts 22, and the mounting member 3 can be divided into multiple third fastening parts 32. Then, during installation, after the cable 100 is inserted into the protective sleeve 200 and reaches the preset position, the second ring member 2, the mounting member 3 and the first ring member 1 can be correspondingly installed on the outer circumferential surface of the protective sleeve 200 and the cable 100.

[0060] Compared with the second embodiment, in this embodiment, there is no restriction on the installation order, that is, it is not necessary to put the mounting part 3 on the cable 100 before the cable 100 is inserted into the protective sleeve 200. Therefore, the fault tolerance of the installation is improved, and the installation efficiency can also be improved to avoid unnecessary rework.

[0061] In some embodiments, the sealing device for the power cable protective sleeve also includes a first hoop (not shown in the figure) and a second hoop (not shown in the figure). The first hoop is arranged on the outer peripheral surface of the first ring-shaped member 1 to fasten multiple first fastening parts 12, and the second hoop is arranged on the outer peripheral surface of the second ring-shaped member 2 to fasten multiple second fastening parts 22.

[0062] It is understood that after the first annular member 1 and the second annular member 2 are installed, the first annular member 1 can be tightened with the first clamp to further secure the connection between the first annular member 1 and the cable 100. Similarly, the second annular member 2 can be tightened with the second clamp to further secure the connection between the second annular member 2 and the protective sleeve 200.

[0063] In addition, it should be noted that the first clamp and the second clamp can also be replaced with iron wire or cable ties.

[0064] Preferably, if Figure 1-Figure 5 As shown, the outer circumference of the first annular member 1 is provided with a first annular groove 15, and the first hoop is provided in the first annular groove 15;

[0065] A second annular groove 25 is formed on the outer circumferential surface of the second annular member 2 , and the second hoop is disposed in the second annular groove 25 .

[0066] That is, the first clamping hoop disposed within the first annular groove 15 can prevent significant vertical displacement between the first clamping hoop and the first annular member 1. Similarly, the second clamping hoop disposed within the second annular groove 25 can also prevent significant vertical displacement between the second clamping hoop and the second annular member 2, further improving the stability of the first and second clamping hoop during use.

[0067] In some embodiments, the radial dimension of the third through hole 31 gradually decreases along the direction from the second annular member 2 to the first annular member 1 , and the radial dimension of one end of the third through hole 31 adjacent to the second annular member 2 is equal to the radial dimension of the second through hole 21 .

[0068] Specifically, if Figure 6 As shown, the third through hole 31 passes through the mounting member 3 in the up-down direction, and the radial dimension of the third through hole 31 gradually decreases from bottom to top. The radial dimension of the lower opening of the third through hole 31 is equal to the radial dimension of the second through hole 21 .

[0069] That is to say, if the height of the protective sleeve 200 port is uneven (i.e., the protective sleeve 200 port has a protruding portion), after the second ring member 2 and the mounting member 3 are connected, the protruding portion of the protective sleeve 200 port can be inserted into the third through-hole 31, thereby avoiding the reduction of the size of the protective sleeve 200 port inserted into the second ring member 2 due to the protrusion of the protective sleeve 200 port. Figure 6 As shown, the outer circumference of the mounting member 3 is generally parallel to the inner circumference of the third through hole 31, that is, the outer circumference of the mounting member 3 gradually decreases from bottom to top, so that the outer circumference of the mounting member 3 is not easy to accumulate external debris, rainwater, etc.

[0070] In some embodiments, the mounting member 3 is provided with a plurality of first connection holes 33, and the plurality of first connection holes 33 are arranged at circumferential intervals along the third through-hole 31. The second annular member 2 is provided with a plurality of second connection holes 26, and the plurality of second connection holes 26 correspond one-to-one to the plurality of first connection holes 33. The first connection holes 33 are connected to the corresponding second connection holes 26 through a connecting member.

[0071] Specifically, if Figures 1-6 As shown, a thread is provided in the second connecting hole 26, and the mounting member 3 and the second annular member 2 can be connected by a screw, that is, one end of the screw passes through the first connecting hole 33 and is threadedly engaged with the second connecting hole 26 to connect the mounting member 3 to the second annular member 2.

[0072] In some embodiments, the first connecting hole 33 penetrates the mounting member 3 along the axial direction of the first annular member 1 ; and / or the second connecting hole 26 penetrates the second annular member 2 along the axial direction of the second annular member 2 .

[0073] It can be understood that the first connecting hole 33 passes through the mounting member 3 , or the second connecting hole 26 passes through the second annular member 2 , or the first connecting hole 33 passes through the mounting member 3 and the second connecting hole 26 passes through the second annular member 2 .

[0074] That is, when the first connection hole 33 passes through the mounting member 3, the mounting member 3 and the second annular member 2 can be conveniently connected via screws. When the second connection hole 26 passes through the second annular member 2, a thread can be provided in the first connection hole 33, and one end of a screw can be passed from bottom to top through the second connection hole 26 and then threadedly engaged with the first connection hole 33 to connect the mounting member 3 to the second annular member 2. When the first connection hole 33 passes through the mounting member 3 and the second connection hole 26 passes through the second annular member 2, the mounting member 3 and the second annular member 2 can be connected via bolts.

[0075] Preferably, the first connection hole 33 passes through the mounting member 3 and the second connection hole 26 passes through the second annular member 2. During use, the blocking assembly of the embodiment of the present invention is placed outdoors for a long time. Using screws for connection will easily rust due to the influence of rain and other factors, making it difficult to disassemble. However, using bolts for connection can facilitate disassembly even after rusting, thereby optimizing the assembly and disassembly of the blocking assembly of the embodiment of the present invention.

[0076] In some embodiments, at least a portion of the outer circumference of the first annular member 1 is provided with external threads, and the wall surface of the third through hole 31 is provided with internal threads matching the external threads, so that the first annular member 1 is threadedly connected to the third through hole 31 .

[0077] Specifically, if Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the outer peripheral surface of the lower end of the first annular member 1 is provided with an external thread, and the wall surface of the upper end of the third through hole 31 is provided with an internal thread.

[0078] It is understandable that after the mounting member 3 is connected to the second annular member 2, the first annular member 1 is threadedly engaged with the mounting member 3. Alternatively, the first annular member 1 is threadedly engaged with the mounting member 3 first, and then the mounting member 3 is connected to the second annular member 2.

[0079] That is to say, the installation sequence between the first annular member 1, the mounting member 3 and the second annular member 2 can be installed in different installation sequences according to actual working conditions, so that the installation method of the sealing assembly of the embodiment of the present invention is diverse.

[0080] In other embodiments, Figure 7 As shown, the sealing assembly of an embodiment of the present invention includes a mounting body 4 surrounded by multiple mounting parts 41, the inner circumference of the mounting body 4 forms a mounting hole, and the mounting hole includes a first section 412, a second section 413 and a third section 414 connected in sequence in the up and down directions, the first section 412 is used to be mounted on the cable 100, and the third section 414 is used to be mounted on the protective sleeve 200.

[0081] like Figure 7 As shown, taking the mounting body 4 surrounded by two mounting parts 41 as an example, the mounting body 4 can be divided into two mounting parts 41 by a cross section along the up and down directions, and each mounting part 41 includes two vertical mounting surfaces 411, and a third protrusion 4111 is provided on the mounting surface 411 of one mounting part 41, and a third groove 4112 matching the third protrusion 4111 is provided on the mounting surface 411 of the other mounting part 41.

[0082] It can be understood that when the cable 100 is inserted into the protective sleeve 200 and reaches the preset position, the two mounting parts 41 are mounted on the outer circumference of the cable 100 and the protective sleeve 200, and the third protrusion 4111 is matched with the third groove 4112 to prevent the two mounting parts 41 from relative displacement in the up and down directions.

[0083] Optionally, the outer circumference of the first section 412 can be fastened with a clamp, and the outer circumference of the third section 414 can also be fastened with a clamp. Of course, wire or cable ties can also be used for fastening.
