Description

[Technical Field]

[0001] This utility model relates to the field of equipment line protection technology, and in particular to an insertable detachable tube-type busbar protection sleeve. [Background Technology]

[0002] Tubular busbars are mainly used in wind power generation and belong to power transmission and distribution equipment. Wind power-specific tubular busbars are used for current transmission between the generator set at the top of the tower and the converter at the bottom. They are vertically installed on the inner wall of the tower.

[0003] Due to tower swaying, the rubber sleeve has become detached from its original position. Once detached, the tubular busbar is not effectively protected, the heat-shrink tubing will wear and crack, exposing the conductors and posing a safety hazard. Therefore, it is necessary to send personnel to the site immediately for repositioning. However, due to limited space and difficulty in movement, repositioning will require significant effort and time. After repositioning, as the tower continues to sway, the rubber sleeve will detach again, creating a continuous cycle that increases the workload for on-site personnel for replacement and maintenance. Simultaneously, the wind turbines on-site are shut down for maintenance, preventing normal power generation and affecting the normal power supply. Therefore, resolving the issue of the rubber sleeve detaching from its original position has become an urgent need. [Utility Model Content]

[0004] To solve the above-mentioned technical problems, this utility model proposes an insertable detachable tube-type busbar protection sleeve.

[0005] This utility model is achieved by the following technical solution:

[0006] An insertable detachable tubular busbar protection sleeve includes a tubular protection sleeve body. The protection sleeve body has a slit along its axial direction for temporary unfolding for installation on a pipeline busbar. A first limiting member with an outer diameter larger than the outer diameter of the protection sleeve body is provided on one axial side of the protection sleeve body, and a second limiting member with an outer diameter larger than the outer diameter of the protection sleeve body is provided on the other axial side of the protection sleeve body for cooperating with the first limiting member to provide limiting space.

[0007] As described above, the insertable detachable tube-type busbar protective sleeve has a first limiting member comprising a plurality of first flanges arranged in a circumferential array on the outer periphery of the protective sleeve body, and a second limiting member comprising a plurality of second flanges arranged in a circumferential array on the outer periphery of the protective sleeve body, which are offset from the first flanges.

[0009] As described above, in the insertable detachable tube-type busbar protective sleeve, the second flange is arranged perpendicularly to the main body of the protective sleeve.

[0010] As described above, the insertable detachable tube-type busbar protective sleeve, the main body of the protective sleeve, the first limiting member, and the second limiting member are all made of materials with good elasticity, flame retardancy, and insulation.

[0011] As described above, the insertable detachable tube-type busbar protective sleeve, the main body of the protective sleeve, the first limiting member, and the second limiting member are all made of natural rubber material.

[0012] As described above, in the insertable detachable tube-type busbar protective sleeve, the cutout is a straight line along the axial direction of the protective sleeve body.

[0013] As described above, the cut of the insertable detachable tube-type busbar protective sleeve has a Z-shaped cross-section.

[0014] As described above, the insertable detachable tube-type busbar protective sleeve has an axial cross-sectional shape of annular wave.

[0015] As described above, in the insertable detachable tubular busbar protective sleeve, the inner diameter of the protective sleeve body corresponds to the outer diameter of the tubular busbar to be protected, the outer diameter of the protective sleeve body corresponds to the through hole at the installation location of the tubular busbar to be protected, the distance between the first flange and the second flange corresponds to the thickness of the plate where the through hole is located, and the outer diameters of both the first flange and the second flange are larger than the outer diameter of the through hole.

[0016] Compared with the prior art, the insertable detachable tube-type busbar protective sleeve proposed in this utility model has the following advantages:

[0017] 1. The first limiting member and the second limiting member can provide a limiting space. After the protective sleeve is installed, the first limiting member and the second limiting member can prevent the protective sleeve from leaving the working area under the action of external force, and avoid the situation where the protective sleeve leaves the working area and the tubular busbar is damaged due to lack of protection.

Detailed Implementation Methods

[0029] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Specific embodiments, combined with Figures 1 to 7 As shown, further illustrating the technical solution of this utility model, an insertable detachable tubular busbar protective sleeve includes a tubular protective sleeve body 1. The protective sleeve body 1 has an axially oriented cutout 11 for temporary unfolding and installation on a tubular busbar. A first limiting member 12 with an outer diameter larger than the outer diameter of the protective sleeve body 1 is provided on one axial side of the protective sleeve body 1, and a second limiting member 13 with an outer diameter larger than the outer diameter of the protective sleeve body 1 is provided on the other axial side of the protective sleeve body 1 to cooperate with the first limiting member 12 and provide limiting space. The cutout 11 allows for convenient installation of the protective sleeve onto the tubular busbar requiring protection without affecting its operation. The first limiting member 12 and the second limiting member 13 provide a limiting space. After the protective sleeve is installed, the first limiting member 12 and the second limiting member 13 prevent the protective sleeve from detaching from the working area under external force, thus preventing damage to the tubular busbar due to lack of protection.

[0031] In this implementation case, see Figure 1 , Figure 2 , Figure 4 The axial cross-sectional shape of the protective sleeve body 1 is annular wavy. The wavy cross-section of the protective sleeve body 1 allows for a certain gap between the protective sleeve body 1 and the tubular busbar, which can reduce and mitigate the vibration caused by the swaying of the tubular busbar, further protecting the tubular busbar. At the same time, the wavy cross-sectional shape of the protective sleeve body 1 can reduce material input and lower production costs while ensuring normal performance.

[0032] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, the protective sleeve body 1, the first limiting member 12, and the second limiting member 13 are all made of materials with good elasticity, flame retardancy, and insulation. As a preferred embodiment of this solution, and not a limitation thereof, the protective sleeve body 1, the first limiting member 12, and the second limiting member 13 are all made of natural rubber. The use of natural rubber as the material for the protective sleeve enables it to have good shock absorption and cushioning performance, which is beneficial for absorbing stress generated during shaking, further protecting the use of the tubular busbar.

[0033] In this implementation case, see Figures 1 to 4 The first limiting member 12 includes a plurality of first flanges 121 arranged in a circumferential array on the outer periphery of the protective sleeve body 1, and the second limiting member 13 includes a plurality of second flanges 131 arranged in a circumferential array on the outer periphery of the protective sleeve body 1, which are offset from the first flanges 121. The offset arrangement of the first flanges 121 and the second flanges 131 simplifies the molds for their production, reduces production costs, and ensures the production process. At the same time, by providing a plurality of first flanges 121, the first limiting member 12 facilitates the installation of the protective sleeve into the working area while ensuring the limiting and locking function.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, see [link to relevant documentation]. Figures 1 to 3 The first flange 121 is inclined relative to the second flange 131. The inclined arrangement of the first flange 121 facilitates the insertion of the protective sleeve into the installation space. As a preferred embodiment of this solution, and not a limitation thereof, the second flange 131 is vertically arranged relative to the protective sleeve body 1. The arrangement of the second flange 131 can prevent the protective sleeve from falling off.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, see [link to relevant documentation]. Figure 3 The first flange 121 is tilted at an angle α relative to the second flange 131, and the range of α is 0° to 90°.

[0036] In this implementation case, see Figure 1 , Figure 2 , Figure 5 The cut 11 is a straight line along the axial direction of the protective sleeve body 1. As a preferred embodiment of this solution, but not a limitation, the cross-sectional shape of the cut 11 is Z-shaped. The cut 11 facilitates the unfolding of the protective sleeve body 1 for installation onto the tubular busbar. The Z-shaped cut 11 facilitates opening the protective sleeve body while concealing the fracture, making the tubular busbar more aesthetically pleasing.

[0037] In this implementation case, see Figure 6 , Figure 7 The inner diameter of the protective sleeve body 1 corresponds to the outer diameter of the tubular busbar to be protected, and the outer diameter of the protective sleeve body 1 corresponds to the through hole 2 at the installation location of the tubular busbar to be protected. The outer diameters of the first flange 121 and the second flange 131 are both larger than the outer diameter of the through hole 2. The protective sleeve body 1 can be installed on the tubular busbar, while avoiding collision and wear between the tubular busbar and the through hole 2, thus achieving a protective function.

[0038] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, the distance between the first flange 121 and the second flange 131 corresponds to the thickness of the plate containing the through hole 2. The distance between the first flange 121 and the second flange 131 provides a certain sliding space for the protective sleeve, allowing it to adjust accordingly when the tubular busbar sways, thus protecting both the tubular busbar and the protective sleeve itself. Simultaneously, the first flange 121 and the second flange 131 limit the movement of the protective sleeve, preventing it from sliding off and affecting its protection of the tubular busbar.

[0039] The working principle of this embodiment is as follows:

[0040] This utility model proposes an insertable detachable tube-type busbar protective sleeve, which provides limiting space through an inclined first flange 121 and a second flange 131 that is perpendicular to the axial direction of the protective sleeve body, thereby preventing the protective sleeve from detaching. The specific principle is as follows:

[0041] The cut 11 can be temporarily opened to install the protective sleeve onto the tubular busbar. At the same time, the elastic, inclined first flange 121 can easily pass through the through hole, protecting the tubular busbar from direct collision and wear with the plate containing the through hole. There is also a gap between the first flange 121 and the second flange, providing a certain sliding space for the protective sleeve. When the tubular busbar shakes, the protective sleeve can adjust accordingly, providing a certain sliding space for the protective sleeve. This protects both the tubular busbar and the protective sleeve itself. In addition, the first flange 121 and the second flange 131 can limit the protective sleeve, preventing it from sliding off and affecting its protection of the tubular busbar.
