[0052] To solve the problems of the above related technologies, the present embodiment provides a protective sleeve and an electric cabinet.
[0053] As shown in Figure 1 and Figure 2 The protective sleeve provided by the present embodiment comprises a protective sleeve body 110 and a heat dissipation ring 130, the protective sleeve body 110 is used to penetrate the cabinet body 200, the protective sleeve body 110 is provided with a threading passage 112 for the cable 300 to pass through, and the circumferential side wall of the protective sleeve body 110 is provided with a plurality of heat dissipation hole structures 111.
[0054] The heat dissipation ring 130 is sleeved on the protective sleeve body 110, and the circumferential side wall of the heat dissipation ring 130 is provided with a plurality of first heat dissipation opening structures 1311, and the first heat dissipation opening structures 1311 are in communication with the heat dissipation hole structures 111.
[0055] Specifically, the protective sleeve body 110 can be a tubular structure, so the protective sleeve body 110 has a threading passage 112 for the cable 300 to pass through.
[0056] The plurality of heat dissipation hole structures 111 can be arranged in a ring shape and spaced apart on the circumference of the protective sleeve body 110, so that the heat generated by the cable 300 can be quickly dissipated from the plurality of heat dissipation hole structures 111 arranged in a ring shape and spaced apart, improving the heat dissipation effect of the cable 300.
[0057] The protective sleeve body 110 penetrates the cabinet body 200 at a certain angle, and the cable 300 passes through the protective sleeve body 110, so as to ensure that the cable 300 can smoothly pass into the inside of the cabinet body 200 through the protective sleeve body 110.
[0058] The circumferential side wall of the heat dissipation ring 130 is provided with a plurality of first heat dissipation opening structures 1311, the number of the first heat dissipation opening structures 1311 of the heat dissipation ring 130 matches the number of the heat dissipation hole structures 111 of the protective sleeve body 110, and the inner diameter of the heat dissipation ring 130 can be slightly larger than the outer diameter of the protective sleeve body 110, so that the heat dissipation ring 130 can be smoothly sleeved on the outside of the protective sleeve body 110.
[0059] Each first heat dissipation opening structure 1311 can adopt a strip-shaped hole which extends along the axial direction of the heat dissipation ring 130.
[0060] The heat dissipation ring 130 can be made of a metal material with good heat dissipation performance, the heat dissipation ring 130 is sleeved on the outside of the protective sleeve body 110, and each first heat dissipation opening structure 1311 of the heat dissipation ring 130 can be aligned and communicated with each heat dissipation hole structure 111 of the protective sleeve body 110, so as to further improve the heat dissipation efficiency of the cable 300.
[0061] In the embodiment, the protective sleeve 100 mainly includes the protective sleeve body 110 and the heat dissipation ring 130, the protective sleeve body 110 penetrates the cabinet 200, and the heat dissipation ring 130 is sleeved on the protective sleeve body 110, so that the heat dissipation ring 130 and the protective sleeve body 110 are fixed on the cabinet 200; since the protective sleeve body 110 has the threading passage 112, the cable 300 can pass through the threading passage 112 of the protective sleeve body 110 to enter the inside of the cabinet 200, not only realizing the connection between the cable 300 and the cabinet 200, but also realizing the isolation between the cable 300 and the cabinet 200, so as to reduce the abrasion of the cable 300 by the cabinet 200 and realize the protection of the cable 300.
[0062] Since the circumferential side wall of the protective sleeve body 110 is provided with a plurality of heat dissipation hole structures 111, the circumferential side wall of the heat dissipation ring 130 is provided with a plurality of first heat dissipation opening structures 1311, the first heat dissipation opening structures 1311 of the heat dissipation ring 130 are communicated with the heat dissipation hole structures 111, so that the heat generated by the cable 300 passing through the protective sleeve body 110 during the working process can be quickly diffused outward from the plurality of heat dissipation hole structures 111 through the corresponding first heat dissipation opening structures 1311, so that the protective sleeve body 110 can effectively improve the heat dissipation effect of the cable 300 on the basis of protecting the cable 300, and correspondingly ensure the actual carrying capacity and use safety of the cable 300.
[0063] Optionally, in combination with the heat dissipation ring 130, the protective sleeve body 110 is provided with a plurality of heat dissipation hole structures 111, and the heat dissipation ring 130 is provided with a plurality of first heat dissipation opening structures 1311. Figure 3 and Figure 4 As shown in the figures, the heat dissipation ring 130 is used to rotate relative to the protective sleeve body 110, so that the first heat dissipation opening structures 1311 are aligned or staggered with the heat dissipation hole structures 111.
[0064] Specifically, the circumferential sidewall of the heat dissipation ring 130 is provided with a plurality of first heat dissipation opening structures 1311, the number of the first heat dissipation opening structures 1311 of the heat dissipation ring 130 matches the number of the heat dissipation hole structures 111 of the protective sleeve body 110, and the inner diameter of the heat dissipation ring 130 can be slightly larger than the outer diameter of the protective sleeve body 110, so that the heat dissipation ring 130 can rotate relative to the protective sleeve body 110.
[0065] In this optional embodiment, when the cabinet body 200 needs to be maintained or the temperature of the cable is low when the cabinet body 200 is running at low load, the heat dissipation ring 130 is rotated, the first heat dissipation opening structures 1311 on the heat dissipation ring 130 are staggered with the heat dissipation hole structures 111 on the protective sleeve body 110, and at this time the heat dissipation ring 130 can shield the heat dissipation hole structures 111 of the protective sleeve body 110 (see Figure 4 illustrated), so as to prevent dust from entering between the protective sleeve body 110 and the cable 300, and to achieve the protection function of the heat dissipation hole structures 111 of the protective sleeve body 110 and the cable 300.
[0066] When the temperature of the cable 300 passing through the protective sleeve body 110 is high during the operation of the cabinet body 200, and the cable 300 after threading needs to be cooled, the heat dissipation ring 130 is rotated, the first heat dissipation opening structures 1311 on the heat dissipation ring 130 are aligned and communicated with the heat dissipation hole structures 111 on the protective sleeve body 110 (see Figure 3 illustrated), and then the heat generated by the cable 300 during operation can be diffused outward through the heat dissipation hole structures 111 and the first heat dissipation opening structures 1311, so as to achieve the heat dissipation function of the cable 300.
[0067] Optionally, in combination with Figure 5 and Figure 6 illustrated, the protective sleeve 100 further comprises a cleaning ring 140, the cleaning ring 140 is embedded between the heat dissipation ring 130 and the protective sleeve body 110, and the cleaning ring 140 is fixedly connected with the inner wall of the heat dissipation ring 130.
[0068] The circumferential sidewall of the cleaning ring 140 is provided with a plurality of second heat dissipation opening structures 141, and each second heat dissipation opening structure 141 is communicated with the corresponding first heat dissipation opening structure 1311.
[0069] Specifically, the inner diameter of the cleaning ring 140 can be greater than or equal to the outer diameter of the protective sleeve body 110, so that the cleaning ring 140 can be smoothly sleeved on the protective sleeve body 110.
[0070] The outer diameter of the cleaning ring 140 can be smaller than the inner diameter of the heat dissipation ring 130, so that the cleaning ring 140 can be embedded in the inner side of the heat dissipation ring 130. The cleaning ring 140 can be fixed to the inner wall of the heat dissipation ring 130 by bonding or the like, so that the cleaning ring 140 can rotate together with the heat dissipation ring 130 relative to the protective sleeve body 110.
[0071] The cleaning ring 140 can be made of a flexible material such as rubber, silicone or the like, so that the cleaning ring 140 has a certain softness, so that the inner wall of the cleaning ring 140 can better contact the outer wall of the protective sleeve body 110.
[0072] A plurality of second heat dissipation opening structures 141 are formed on the cleaning ring 140, and the number and arrangement of the second heat dissipation opening structures 141, the first heat dissipation opening structures 1311 and the heat dissipation hole structures 111 are the same.
[0073] In this optional embodiment, since each of the second heat dissipation opening structures 141 is in communication with the corresponding first heat dissipation opening structure 1311, the cleaning ring 140 will not hinder the heat dissipation of the cable 300 from the heat dissipation hole structures 111 of the protective sleeve body 110 through the first heat dissipation opening structures 1311 of the heat dissipation ring 130; Furthermore, during the rotation of the cleaning ring 140 together with the heat dissipation ring 130 relative to the protective sleeve body 110, the dust near the heat dissipation hole structures 111 of the protective sleeve body 110 can be cleaned by the cleaning ring 140 in a rotating friction manner, so as to avoid the dust from blocking the heat dissipation hole structures 111 of the protective sleeve body 110, and the heat dissipation effect of the cable 300 is ensured.
[0074] Optionally, in combination with Figure 7 As shown, the cleaning ring 140 is spaced apart from the inner wall of the protective sleeve body 110 by a plurality of brush head structures 142.
[0075] Specifically, each brush head structure 142 can include a plurality of protrusions. The brush head structure 142 and the second heat dissipation opening structure 141 are alternately distributed, and the number of the brush head structure 142 can be the same as the number of the heat dissipation hole structure 111 of the protective sleeve body 110.
[0076] The brush head structure 142 and the inner wall of the cleaning ring 140 can be configured as an integral structure, so as to ensure the connection stability of the brush head structure 142 and the cleaning ring 140.
[0077] In this optional embodiment, during the rotation of the cleaning ring 140 together with the heat dissipation ring 130 relative to the protective sleeve body 110, the brush head structure 142 protruding from the inner wall of the cleaning ring 140 can improve the cleaning effect of the dust near the heat dissipation hole structure 111 on the protective sleeve body 110 during the rotation.
[0078] Optionally, in combination with Figure 8As shown, the heat dissipation ring 130 comprises a heat dissipation ring body 131 and two limiting protrusions 132, the two limiting protrusions 132 are arranged on the inner side wall of the heat dissipation ring body 131 along the axial direction of the protective sleeve body 110, and the cleaning ring 140 is fixed between the two limiting protrusions 132.
[0079] Specifically, the limiting protrusion 132 is arranged on the inner wall of the heat dissipation ring 130, and the limiting protrusion 132 can be a ring-shaped protrusion structure (see Figure 5 As shown, it can also be a plurality of protrusion structures arranged in a ring shape.
[0080] The two limiting protrusions 132 can be arranged on the inner walls of the axial ends of the heat dissipation ring body 131 (see Figure 5 As shown, they can also be arranged between the axial ends of the heat dissipation ring body 131.
[0081] The spacing between the two limiting protrusions 132 can be slightly larger than the size of the cleaning ring 140 along the axial direction of the cleaning ring 140, so that the cleaning ring 140 can be smoothly fixed between the two limiting protrusions 132.
[0082] In this optional embodiment, since the cleaning ring 140 can be fixed between the two limiting protrusions 132, the two limiting protrusions 132 can play an axial limiting role on the cleaning ring 140, effectively preventing the cleaning ring 140 from being axially displaced relative to the heat dissipation ring 130, and accordingly enhancing the assembly stability of the cleaning ring 140 and the heat dissipation ring 130.
[0083] Optionally, in combination with Figure 9 and Figure 10 As shown, the protective sleeve further comprises a stop ring 150, the stop ring 150 is sleeved on the protective sleeve body 110, and the stop ring 150 is arranged on the outer side of the cabinet 200.
[0084] Specifically, the inner diameter of the stop ring 150 is greater than or equal to the protective sleeve body 110, so that the stop ring 150 can be smoothly sleeved on the protective sleeve body 110.
[0085] In this optional embodiment, since the protective sleeve base 150 and the stop ring 150 are both sleeved on the protective sleeve body 110, and the protective sleeve base 150 and the stop ring 150 are respectively on the inner side and the outer side of the cabinet 200, the protective sleeve base 150 and the stop ring 150 respectively play an axial limiting role on the protective sleeve body 110 relative to the cabinet 200, for example, the protective sleeve base 150 can prevent the protective sleeve body 110 from being separated outwardly from the cabinet 200, and the stop ring 150 can prevent the protective sleeve body 110 from entering the cabinet 200 inwardly, thereby increasing the connection stability of the protective sleeve 100 and the cabinet 200.
[0086] Optionally, the stop ring 150 is threadedly connected with the protective sleeve body 110.
[0087] Specifically, an inner thread can be arranged on the inner wall of the stop ring 150, and an outer thread is arranged at the corresponding position of the protective sleeve body 110, so that the stop ring 150 can be threadedly sleeved on the protective sleeve body 110.
[0088] In this optional embodiment, since the stop ring 150 is threadedly connected with the protective sleeve body 110, during the process of threadedly sleeving the stop ring 150 on the protective sleeve body 110, the protective sleeve body 110 can be driven to move outwardly of the cabinet 200 by the continuous rotation of the stop ring 150 relative to the protective sleeve body 110, and correspondingly, the stop ring 150 is more closely connected with the inner wall of the cabinet 200, thereby improving the connection stability of the protective sleeve 100 and the cabinet 200.
[0089] Optionally, in combination with Figure 11 As shown in
[0090] The heat dissipation ring 130 is made of a magnetic material and is magnetically connected with the magnetic ring 160.
[0091] Specifically, the magnetic ring 160 can be a circular ring structure with magnetic adsorption effect. The heat dissipation ring 130 can be made of a magnetic material and can be adsorbed by the magnetic ring 160, for example, the heat dissipation ring 130 can be an iron ring, and the magnetic ring 160 can adsorb the heat dissipation ring 130 by its own magnetic property. The magnetic ring 160 can be fixed to the inner wall end of the stop ring 150 by adhesion, clamping or other ways.
[0092] In this optional embodiment, the magnetic ring 160 fixed to the stop ring 150 is magnetically connected with the heat dissipation ring 130, and the stop ring 150 is fixedly sleeved on the protective sleeve body 110, so that the heat dissipation ring 130 is magnetically adsorbed by the magnetic ring 160, thereby effectively preventing the heat dissipation ring 130 from being separated from the protective sleeve body 110 and further improving the installation stability of the heat dissipation ring 130 and the protective sleeve body 110.
[0093] Optionally, in combination with Figure 12 、 Figure 13 and Figure 17 As shown in
[0094] Specifically, the diameter of the first sealing ring 170 is greater than the protective sleeve body 110, so that the first sealing ring 170 can be smoothly sleeved on the protective sleeve body 110.
[0095] In this optional embodiment, since the first sealing ring 170 is sleeved on the protective sleeve body 110 and is located between the protective sleeve body 110 and the cabinet 200, the first sealing ring 170 not only plays a sealing role between the protective sleeve 100 and the cabinet 200, but also can enhance the connection stability of the protective sleeve 100 and the cabinet 200.
[0096] Furthermore, in combination with Figure 13 and Figure 17 It is shown that the protective sleeve 100 further comprises a second sealing ring 180, which is arranged between the heat dissipation ring 130 and the protective sleeve body 110, so that the second sealing ring 180 can enhance the smoothness of the heat dissipation ring 130 during rotation relative to the protective sleeve body 110, and the second sealing ring 180 can limit the axial displacement of the heat dissipation ring 130 relative to the protective sleeve body 110, and the stop ring 150 is sleeved outside the protective sleeve body 110, which correspondingly prevents the stop ring 150 from rotating to a position and loosening the protective sleeve body 110.
[0097] Optionally, in combination with Figure 14 to Figure 16 It is shown that the protective sleeve further comprises a wire passing sleeve 120, which can adopt a structural mode as follows, for example, the wire passing sleeve 120 comprises an annular connecting portion 121 and a plurality of sector-shaped movable pieces 122 arranged in an annular arrangement, the annular connecting portion 121 is connected with the protective sleeve body 110, and the arc-shaped edges of each sector-shaped movable piece 122 are respectively connected with the annular connecting portion 121, each sector-shaped movable piece 122 is used to be in an open state when the cable 300 is threaded through the annular connecting portion 121, and is used to be in a closed state when the cable 300 is separated from the annular connecting portion 121.
