All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0028] See also Figures 1-9 , an embodiment of the present invention provides an insulating protective cover for exposed joints of a power generation vehicle, the insulating protective cover for exposed joints of the power generation vehicle comprising: A plurality of protective outer shells 1 are provided, and adjacent protective outer shells 1 are connected by a wave-shaped elastic plate 18. A protective inner sleeve 15 is fixedly installed in the protective outer shell 1, and an expansion space 17 is formed between the protective outer shell 1 and the protective inner sleeve 15; and a sealing detection assembly, which is connected to the protective outer shell 1 and the protective inner liner 15 respectively, wherein the sealing detection assembly includes an inflatable sealing unit and an elastic detector 19; There are multiple elastic detectors 19, which are evenly distributed in the expansion space 17 and fixedly connected to the inner wall of the protective outer shell 1.

[0029] See also Figures 1-9, and also includes: a rubber sleeve 3, the number of the rubber sleeve 3 is multiple, the multiple rubber sleeves 3 are respectively sleeved on the multiple wavy elastic plates 18, and the rubber sleeve 3 is also fixedly connected to the protective outer shell 1.

[0030] The inflatable sealing unit comprises: a self-closing inflation port 2, which is fixedly mounted on the protective outer shell 1 and is also in communication with the expansion space 17; and a hard support portion 16 , which is fixedly mounted on the protective inner sleeve 15 , wherein each protective inner sleeve 15 is symmetrically provided with two hard support portions 16 , and the hard support portion 16 is also fixedly connected to the elastic detector 19 .

[0031] When insulating the exposed joints of the power generation vehicle, first, the joints of one or more cables can be placed in multiple protective inner sleeves 15 respectively (the specific operation method is to insert multiple cables into multiple protective inner sleeves 15 respectively before connecting the joints, and then connect the joints. After the connection is completed, the protective outer shell 1 and the protective inner sleeve 15 are pulled by manpower to slide the protective outer shell 1 and the protective inner sleeve 15 to the joint, that is, the joint part is placed in the appropriate position in the protective inner sleeve 15, which will not be described in detail here). Then, the sealing detection component is started, that is, an external air pump is used to inflate the expansion space 17 through multiple self-closing air inlets 2. After the expansion space 17 is filled with gas, under the action of air pressure, on the one hand, the protective outer shell 1 can be slightly expanded, and on the other hand, the protective inner sleeve 15 close to the cable diameter can be pressed against the cable, thereby ensuring the sealing of the cable, and after the distance between the protective outer shell 1 and the protective inner sleeve 15 increases, that is, the expansion space 1 After the volume of 7 increases, the detection function of the elastic detector 19 can facilitate the staff to understand the protection status of the protective inner sleeve 15 on the cable joint and the cables near the joint. Among them, the elastic detector 19 can be in the form of a spring and a pressure sensor. After the spring is deformed, the value can be transmitted to the staff's mobile terminal after detection by the pressure sensor, so that the protection status of the joint can be monitored in real time. I will not go into details here. In addition, the wavy elastic plate 18 is set to adjust the spacing between adjacent protective outer shells 1, so that multiple joints can be adjusted synchronously in an overall form, and the shapes of multiple protective outer shells 1 can be adjusted according to the use place and space limitations, such as rectangular or circular distribution, etc., thereby improving the practicality and flexibility of the device, simple operation, and can protect the exposed joints of multiple cables at the same time, and can ensure good sealing, and can monitor the sealing in real time to ensure the safe use of electrical equipment and provide convenience for the staff.

[0032] In one embodiment of the present invention, see Figures 1-9 , further comprising: a soft head 12, wherein the number of the soft head 12 is multiple, and the multiple soft heads 12 are fixedly connected to the end of the protective outer shell 1; A communication hole 5 is provided on the soft head 12 and communicates with the protective inner sleeve 15; and a clamping and sealing mechanism, the clamping and sealing mechanism being connected to the soft head 12 and the wavy elastic plate 18 respectively, wherein the clamping and sealing mechanism comprises a compression sealing component and a rotation and contraction component; The compression sealing assembly is fixedly connected to the wavy elastic plate 18 and is also detachably connected to the soft head 12. The rotational contraction assembly is connected to the soft head 12 and is installed in conjunction with the compression sealing assembly.

[0033] It also includes: a limiting head 4 , and the number of the limiting heads 4 is multiple, and the multiple limiting heads 4 are respectively fixedly installed on the ends of the multiple soft heads 12 .

[0034] Under the control of the rotating and shrinking component, the distance between adjacent protective outer shells 1 can be adjusted, and at the same time, the compression sealing component can produce an extrusion effect on the soft head 12. On the one hand, it can further ensure the sealing protection effect of the protective inner sleeve 15 on the joint. On the other hand, it can prevent the cable from loosening at the joint due to external force, thereby further ensuring the safety of electrical equipment.

[0035] In one embodiment of the present invention, see Figures 1-9 , the compression sealing assembly comprises: There are multiple V-shaped elastic plates 6, and the multiple V-shaped elastic plates 6 are fixedly connected to the multiple wavy elastic plates 18 respectively; And an arc-shaped pressure head 7, the number of the arc-shaped pressure heads 7 is multiple, wherein an arc-shaped pressure head 7 is fixedly installed on both sides of each of the V-shaped elastic plates 6, and a soft head 12 is arranged between the two oppositely arranged arc-shaped pressure heads 7, and the arc-shaped pressure head 7 and the soft head 12 are detachably connected.

[0036] See also Figures 1-9 , the rotation and contraction assembly includes: A guide plate 9, wherein the guide plate 9 is fixedly connected to the soft head 12; A fastening rope 8, the fastening rope 8 passes through the plurality of guide plates 9 and is slidably connected to the guide plates 9, and support plates 11 are fixedly mounted on both ends of the fastening rope 8, and each support plate 11 is fixedly mounted with a second arc-shaped pressure head 10, and the second arc-shaped pressure head 10 is detachably connected to the soft head 12; and a tightening drive unit, wherein the tightening drive unit is connected to the supporting plate 11 and to the tightening rope 8 .

[0037] The tightening drive unit comprises: An adjusting cylinder 14, wherein the adjusting cylinder 14 is fixedly mounted on the supporting plate 11; A guide chute plate 13, wherein the number of the guide chute plates 13 is multiple, and the multiple guide chute plates 13 are all fixedly mounted on the supporting plate 11 and are all connected to the adjusting cylinder 14; and a winding module, which is inserted into the adjusting cylinder 14 and is rotatably connected to the adjusting cylinder 14, wherein a plurality of the fastening ropes 8 pass through the guide slide plate 13 and are connected to the winding module.

[0038] The winding module comprises: a rotating shaft 27, one end of which is rotatably connected to the inner wall of the adjusting cylinder 14, and the other end of which passes through the adjusting cylinder 14 and is rotatably connected to the adjusting cylinder 14; A rotating head 20, the rotating head 20 is fixedly mounted on the other end of the rotating shaft 27; and a winding portion 26 , which is located inside the adjusting cylinder 14 and on the rotating shaft 27 , and is also connected to the fastening rope 8 .

[0039] See also Figures 1-9 , further comprising: a positioning circular plate 24, the positioning circular plate 24 being fixedly mounted in the adjusting cylinder 14, wherein the rotating shaft 27 passes through the positioning circular plate 24 and is rotatably connected to the positioning circular plate 24; There are multiple sockets 25, and the sockets 25 are evenly arranged on the positioning circular plate 24; A positioning telescopic rod 22, one end of which passes through the rotating head 20 and is detachably connected to the socket 25, and the other end of the positioning telescopic rod 22 is fixedly mounted with a push-pull protrusion 21; And a baffle 28 , the baffle 28 is fixedly mounted on the positioning telescopic rod 22 , and a plug spring 23 is provided between the baffle 28 and the rotating head 20 , and the plug spring 23 is sleeved on the positioning telescopic rod 22 .

[0040] When adjusting the spacing between adjacent protective outer shells 1 and squeezing and limiting the soft head 12, first, by manually pulling the push-pull protrusion 21, try to move the positioning telescopic rod 22 toward the outside of the rotating head 20. At this time, the positioning telescopic rod 22 is separated from the socket 25, and the plug spring 23 is in a compressed state. Then, due to the eccentric arrangement between the positioning telescopic rod 22 and the rotating head 20, the positioning telescopic rod 22 is manually rotated, so that the rotating head 20 can be rotated on the adjusting cylinder 14 and the rotating shaft 27 can be driven to rotate synchronously. At this time, during the rotation of the rotating shaft 27, the fastening rope 8 can be continuously wound at the winding portion 26. During the winding process of the fastening rope 8, the length of the fastening rope 8 exposed to the outside of the guide slide plate 13 becomes shorter, thereby reducing the distance between adjacent protective outer shells 1. At this time, the V-shaped elastic plate 6 and the wavy elastic plate 18 are both in a compressed state, so that when danger occurs or the cables are disassembled, , so that each component is reset and the distance between adjacent protective outer shells 1 is increased to ensure the safety of power connection. I will not go into too much detail here. Under the pushing action of the V-shaped elastic plate 6, the arc pressure head 1 7 can produce an extrusion effect on the soft head 12, which is similar to the structure of a splint. Under the pressure of the arc pressure head 1 7 and the arc pressure head 2 10, and because the arc pressure head 1 7 and the arc pressure head 2 10 are arc-shaped structures, the soft head 12 will be deformed, thereby increasing the friction between the cable in the connecting hole 5 and further ensuring the sealing effect. After tightening to a certain extent or meeting the tightening requirement, the positioning telescopic rod 22 is loosened. Under the elastic force of the plug-in spring 23, the positioning telescopic rod 22 will be extended into a certain socket 25 on the positioning circular plate 24 again, thereby limiting the rotating head 20 and preventing the rotating head 20 from driving the rotating shaft 27 to reverse, thereby loosening the fastening rope 8. I will not go into too much detail here.
