DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] In one embodiment, if Figures 1 to 6 As shown, the utility model provides a high-toughness anti-hazard waterproof column pipe plugger, including a plugging component, the plugging component includes a shell 4, the edge position of the shell 4 is provided with a first waterproof component, the first waterproof component is used to seal and abut with the outer end of the column pipe 6, the middle part of the shell 4 is provided with a through hole, the hole wall of the through hole is provided with a second waterproof component, the second waterproof component is used to seal and abut with the surface of the cable body 1 passing through the through hole, the side of the shell 4 provided with the first waterproof component is provided with an outer conflict component 7, an inner conflict component 9 and a conflict driving component 8, the conflict driving component 8 is respectively connected to the outer conflict component 7 and the inner conflict component 9 in transmission, wherein the outer conflict component 7 includes an outer conflict block 71, and the inner conflict component 9 includes an inner conflict block 91;

[0030] The staff puts the plugging assembly on the cable body 1, and allows the terminal of the cable body 1 to pass through the column tube 6 and enter the power equipment. At this time, the outer contact assembly 7 and the inner contact assembly 9 are respectively located at the initial positions, such as Figure 4 As shown, the outer abutment block 71 is spaced apart from the inner tube wall of the column tube 6, and the inner abutment block 91 is spaced apart from the surface of the cable body 1, so that before the formal plugging, the cable body 1 can further adjust the plugging position, so that the length of the cable body 1 inside the power equipment is convenient for power transmission and connection;

[0031] After adjusting the position and making the first waterproof component frictionally contact with the column tube 6, after completing the initial limiting of the column tube 6, under the drive of the contact driving member 8, the outer contact block 71 frictionally contacts with the inner tube wall of the column tube 6, and the inner contact block 91 frictionally contacts with the surface of the cable body 1, so that the sealing component is positioned on both sides between the column tube 6 and the cable body 1, and the installation is convenient and quick. The first waterproof component is used to seal the gap at the outer connection position between the outer shell 4 and the column tube 6, and the second waterproof component is used to seal the gap at the outer connection position between the outer shell 4 and the cable body 1, so as to realize the waterproof sealing of the gap between the column tube 6 and the cable body 1, effectively prevent rainwater from entering the column tube 6, realize the protection of the cable body 1, and ensure the normal use of the cable body 1.

[0032] For example, see Figures 2 to 4 as well as Figure 6 The outer resistance assembly 7 also includes a side plate 43 and an outer resistance plate 73. The side of the housing 4 provided with the first waterproof component is fixedly connected with the side plate 43. The side plate 43 is provided with a plurality of resistance windows 72. The plurality of resistance windows 72 are evenly distributed in the circumference. The side of the side plate 43 facing the axis direction of the housing 4 is rotatably connected with the outer resistance plate 73. The outer resistance plate 73 is arranged corresponding to the resistance window 72. The outer resistance plate 73 is transmission-connected with a first torsion spring on the rotation connection shaft of the outer resistance plate 73 and the side plate 43. The side of the outer resistance plate 73 facing the resistance window 72 is fixedly connected with an outer resistance block 71. When the outer resistance block 71 is in the blocking position, the outer resistance block 71 passes through the resistance window 72 and frictionally resists the inner tube wall of the column tube 6. When the side plate 43 extends into the interior of the column tube 6, the outer resistance block 71 is in the initial position, such as Figure 4 As shown, at this time, when the staff operates the rotation of the outer shell 4 for circumferential adjustment, it will not be hindered by the column tube 6. After the position of the outer shell 4 is adjusted, the outer shell 4 is blocked and fixed, and the outer contact block 71 is used to frictionally contact with the inner tube wall of the column tube 6 to achieve the positioning and installation between the outer shell 4 and the column tube 6.

[0033] It should be noted that if Figure 3 and Figure 4 As shown, the outer wall of the side plate 43 is spaced apart from the inner wall of the column tube 6, so that the side plate 43 can be inserted into the interior of the column tube 6 and the installation is convenient.

[0034] like Figure 3 As shown, there are multiple outer abutment blocks 71, and multiple outer abutment blocks 71 are arranged in an array on the side plate 43 to increase the friction points between the outer abutment assembly and the inner wall of the column tube 6, so that the column tube 6 is evenly stressed in the circumferential direction.

[0035] For example, see Figures 2 to 4The inner resistance assembly 9 also includes an inner resistance plate 92, which is rotatably connected to the outer shell 4. A second torsion spring is transmission-connected to the rotational connection shaft between the inner resistance plate 92 and the outer shell 4. A plurality of inner resistance blocks 91 are fixedly connected to the side of the inner resistance plate 92 away from the outer resistance plate 73.

[0036] It should be noted that, in the above embodiment, when the outer shell 4 drives the side plate 43 to shift to the predetermined position inside the column tube 6, the inner contact block 91 is spaced apart from the surface of the cable body 1, and under the drive of the contact driving member 8, the plurality of inner contact blocks 91 frictionally contact with the surface of the cable body 1 to circumferentially embrace and clamp the cable body 1, and position the cable body 1 in the column tube 6, so as to avoid the cable body 1 being dragged during subsequent maintenance of the power equipment, causing the cable body 1 to slide in the column tube 6 and wear the insulating layer of the cable body 1, thereby protecting the cable body 1, and the plurality of inner contact blocks 91 lift the cable body 1 located in the column tube 6, so that the cable body 1 and the column tube 6 are spaced apart, which is convenient for air circulation and heat dissipation of the cable body 1.

[0037] For example, see Figures 2 to 4 The abutment driving member 8 includes a blocking member, a guide rod 82, a spring 83 and a protrusion 84. The blocking member is arranged on the housing 4. The blocking member is transmission-connected to the guide rod 82. The guide rod 82 passes through the housing 4 and is slidingly connected to the housing 4. One end of the guide rod 82 that passes through the inner side of the housing 4 is fixedly connected with a protrusion 84. The arc surface of the protrusion 84 frictionally contacts the surface of the outer abutment plate 73 and the inner abutment plate 92 respectively. The guide rod 82 is located between the protrusion 84 and the housing 4. A spring 83 is sleeved on the portion of the guide rod 82 located between the protrusion 84 and the housing 4. One end of the spring 83 is fixedly connected to the protrusion 84, and the other end of the spring 83 is fixedly connected to the housing 4.

[0038] For example, see Figures 3 to 5 The blocking member includes a baffle 2, a limit block 81 and a fastening bolt 3. The guide rod 82 is located at one end outside the shell 4 and is fixedly connected to the limit block 81. The baffle 2 is located on the side of the limit block 81 away from the shell 4. The baffle 2 is fixedly connected to the shell 4 by the fastening bolt 3. When the blocking assembly is in the blocking position, the baffle 2 and the limit block 81 are frictionally opposed.

[0039] In the above embodiment, according to Figure 4As shown, after the housing 4 is installed on the column tube 6, the baffle 2 inserted on the cable body 1 is moved from one side of the limit block 81 toward the housing 4 to press the limit block 81, so that the protrusion 84 respectively abuts the outer contact plate 73 and the inner contact plate 92. At this time, the plurality of limit blocks 81 are shifted into the slots 811 provided on the end surface of the housing 4, and the baffle 2 is fixedly mounted on the housing 4 by means of a plurality of fastening bolts 3. When the cable body 1 needs to be disassembled for maintenance, the fastening bolts 3 are removed, and the protrusion 84 is shifted to the outer contact plate 73 under the elastic force of the spring 83. Figure 4 The outer contact plate 73 swings back to the initial position under the reset action of the first torsion spring, and the inner contact plate 92 swings back to the initial position under the reset action of the second torsion spring. The outer shell 4 can be easily removed by pulling it outward, and disassembly is convenient.

[0040] In one embodiment, continue to refer to Figures 2 to 6 The first waterproof member includes a limiting flange 41 and a sealing gasket 42. The edge of the housing 4 is provided with a limiting flange 41, and a sealing gasket 42 is embedded in one end of the limiting flange 41 facing the column tube 6. The sealing gasket 42 is used to frictionally contact with the outer end of the column tube 6. The gap at the outer connection position of the housing 4 and the column tube 6 is sealed by the friction between the sealing gasket 42 and the outer end of the column tube 6.

[0041] Exemplarily, the sealing gasket 42 is provided with a limiting groove at one end facing the column tube 6, and the outer end of the column tube 6 is plugged into and abutted against the sealing gasket 42 through the limiting groove. While the column tube 6 and the sealing gasket 42 are plugged into and abutted against each other for sealing, the connection position of the housing 4 and the column tube 6 is limited by the limiting groove.

[0042] Exemplarily, the second waterproof component includes a sealing ring 5, which is fixedly connected to the hole wall of the through hole, and the side of the inner contact plate 92 close to the outer shell 4 is fixedly connected with an extrusion block 51, and the extrusion block 51 is arranged adjacent to one side of the cable body 1. When the inner contact plate 92 swings to the contact position, the extrusion block 51 swings synchronously until the extrusion block 51 and the sealing ring 5 are frictionally in contact, and the sealing ring 5 and the surface of the cable body 1 are frictionally in contact. After the inner contact block 91 contacts and clamps the cable body 1 to position it, the friction between the extrusion block 51 and the sealing ring 5 is used to seal the gap at the outer connection position of the outer shell 4 and the cable body 1, and the function of the sealing gasket 42 is combined to achieve waterproof sealing of the gap between the column tube 6 and the cable body 1, effectively preventing rainwater from entering the column tube 6, protecting the cable body 1, and ensuring the normal use of the cable body 1.

[0043] It should be noted that, when the column tube plugger is in use, the cable body 1 is passed through the baffle 2 and the housing 4 in sequence, and further passed through the column tube 6 to enter the interior of the power equipment to connect the cable body 1. In order to reserve a sufficient length of the cable body 1 inside the power equipment for power connection and maintenance, at this time, the position of the cable body 1 on the housing 4 is adjusted. After the position is determined, the staff can extend the side plate 43 on the housing 4 into the column tube 6, and with the help of the limiting groove on the sealing gasket 42, the friction abutment with the outer end of the column tube 6 is achieved, on the one hand, the sealing treatment of the gap at the connection position between the housing 4 and the outer side of the column tube 6 is achieved, and on the other hand, the housing 4 is accurately installed on the column tube 6;

[0044] Then, the staff moves the baffle 2 so that the baffle 2 contacts the plurality of limit blocks 81, and fixes the baffle 2 to the housing 4 with the help of the fastening bolts 3. At this time, the protrusions 84 respectively contact the outer contact plate 73 and the inner contact plate 92 with friction, so as to achieve the friction between the outer contact block 71 and the inner tube wall of the column tube 6, and the friction between the inner contact block 91 and the surface of the cable body 1. While the blocking component is positioned and installed between the column tube 6 and the cable body 1, the cable body 1 located in the column tube 6 is clamped and lifted with the help of the plurality of inner contact blocks 91, so that the cable body 1 and the column tube 6 are spaced apart, so as to avoid the cable body 1 from shifting and rubbing against the column tube 6 when the cable body 1 is dragged for maintenance of the electric power equipment, resulting in damage to the insulation layer, and facilitating air circulation, so as to achieve the heat dissipation effect on the cable body 1.

[0045] In addition, when the inner contact plate 92 is shifted to Figure 3 When in the position shown, the sealing ring 5 is squeezed with the help of the extrusion block 51, so that the sealing ring 5 and the surface of the cable body 1 are frictionally contacted, thereby sealing the gap at the outer connection position between the outer shell 4 and the cable body 1, and combined with the effect of the sealing gasket 42, the gap between the cable body 1 and the column tube 6 is waterproofly sealed.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
