[0021] In order to make the technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples.
[0022] The utility model provides a technical scheme: refer to Figure 1 - Figure 5 The utility model discloses a kind of MPP power pipes with high compression resistance structure, including several MPP power pipe bodies 1, the outer circumferential side of several MPP power pipe bodies 1 is equipped with connecting mechanism 2, and MPP power pipe body 1 is equipped with buffer mechanism 3.
[0023] In this embodiment, the improved MPP power pipe is used, and the operator can connect and fix several MPP power pipe bodies 1 through the connecting mechanism 2, so as to form a MPP power pipe with a corresponding length to meet the use demand of the MPP power pipe;
[0024] During the use of the MPP power pipe, if the internal wire part position is short-circuit burst, the buffer mechanism 3 can offset and buffer the wire burst impact force, so as to avoid the impact force of the MPP power pipe exceeding the bearing threshold of the pipe wall of the MPP power pipe body 1, which causes the MPP power pipe to be damaged;
[0025] When the MPP power pipe is subjected to external force, since the pipe wall of the MPP power pipe body 1 is relatively thin, the MPP power pipe can be easily bent and deformed to a certain extent, so as to release the external impact force received by the MPP power pipe, thereby avoiding the impact force received by the pipe wall of the MPP power pipe exceeding the bearing threshold of the pipe wall of the MPP power pipe body 1, which causes the MPP power pipe to be damaged, and after the external force received by the MPP power pipe disappears, the MPP power pipe is quickly deformed and reset due to the pushing of the buffer mechanism 3 to the pipe wall of the MPP power pipe body 1.
[0026] In a further preferred embodiment of the utility model, as shown in Figure 1 - Figure 3 The pipe wall of the MPP power pipe body 1 is fixedly provided with a reinforcing rib 4, and the reinforcing rib 4 is provided in a mesh tube shape, and the reinforcing rib 4 is integrally casted by a plurality of elastic metal wires.
[0027] In this embodiment, the reinforcing rib 4 can enhance the strength of the pipe wall of the MPP power pipe body 1, so as to avoid the influence of the small strength of the thin MPP power pipe body 1 on the use of the MPP power pipe.
[0028] In a further preferred embodiment of the utility model, as shown in Figure 1 and Figure 3As shown, the connecting mechanism 2 comprises a plurality of limiting sleeves 22, and a limiting ring 21 in a semicircular cross-sectional shape is fixedly sleeved on the outer periphery of each end of the MPP power pipe body 1, and the limiting sleeve 22 is sleeved on the outer periphery of the corresponding two limiting rings 21.
[0029] In the embodiment, when the MPP power pipe is assembled, the operator inserts the two ends of the MPP power pipe body 1 into the openings at the two ends of the limiting sleeve 22 respectively, so that a constraint force is applied to the two MPP power pipe bodies 1 through the mutual interference between the limiting ring 21 and the inner wall of the limiting sleeve 22, and the two MPP power pipe bodies 1 are more stably connected together, and the operator can splice a plurality of MPP power pipe bodies 1 according to needs to form an MPP power pipe with a corresponding length to meet the use requirements.
[0030] In a further preferred embodiment of the utility model, as shown in Figure 3 The limiting sleeve 22 is supported by soft plastic, and the outer periphery of the limiting ring 21 is inserted into the corresponding inner groove of the corresponding limiting sleeve 22 and in contact with the inner wall of the corresponding limiting sleeve 22.
[0031] In the embodiment, when the outer wall of the MPP power pipe body 1 is damaged, the operator pulls the damaged MPP power pipe body 1 and the adjacent MPP power pipe body 1 to the two sides, so that a great interference force is generated between the limiting ring 21 and the inner wall of the limiting sleeve 22, and the opening of the limiting sleeve 22 is enlarged along the outer ring wall of the limiting ring 21, the limiting ring 21 is pulled out of the limiting sleeve 22, so that the damaged MPP power pipe body 1 can be disassembled, and then a new MPP power pipe body 1 is replaced on the MPP power pipe according to the above, so that the MPP power pipe body 1 can be repaired, and the use cost of the MPP power pipe is reduced.
[0032] In a further preferred embodiment of the utility model, as shown in Figure 1 and Figure 4 The buffering mechanism 3 comprises an asbestos pad 31, the asbestos pad 31 is arranged in the corresponding MPP power pipe body 1, and the asbestos pad 31 is in a cylindrical shape, the outer periphery wall of the asbestos pad 31 is fixedly connected with the inner wall of the corresponding MPP power pipe body 1, and the length of the asbestos pad 31 is the same as the length of the corresponding MPP power pipe body 1.
[0033] In the embodiment, the asbestos pad 31 can enhance the fireproof performance of the inner side of the pipe wall of the MPP power pipe body 1.
[0034] In a further preferred embodiment of the utility model, as shown in Figure 4 and Figure 5 A plurality of elastic sleeves 32 are fixedly arranged in the asbestos pad 31 in a circumferential arrangement, and the adjacent two elastic sleeves 32 are in contact, and the elastic sleeve 32 is filled with epoxy glue and nitrogen.
[0035] In this embodiment, when the above-mentioned part of the wire position short circuit burst, the impact force will impact on the elastic sleeve 32, the elastic sleeve 32 through the compression of the internal gas, the adaptive deformation of the internal structure of the elastic sleeve 32, so that the elastic sleeve 32 internal gas to the elastic sleeve 32 inner wall of the thrust offset the impact force generated when the wire burst, so that the MPP power tube body 1 pipe wall will only withstand smaller impact force, with the reinforcement rib 4 on the MPP power tube body 1 pipe wall of the constraint limit, so that the MPP power tube body 1 pipe wall almost will not be damaged due to the larger impact force;
[0036] When the MPP power tube is damaged due to the gnawing of rats or insects and other animals, the epoxy glue in the elastic strip is sprayed out, and due to the interception of the asbestos pad 31, the epoxy glue will not completely flow out of the MPP power tube, the hole on the MPP power tube is filled with epoxy glue, and due to the contact of the epoxy glue with air, the epoxy glue is relatively fast to coagulate, thereby repairing the MPP power tube to some extent and prolonging the use time of the MPP power tube.
[0037] Working principle: when the improved MPP power tube is assembled, the operator will limit the sleeve 22 on the outer circumferential side of the MPP power tube body 1, in the process of limiting the sleeve 22 on the limiting ring 21, the operator presses the limiting ring 21 and the MPP power tube body 1, so as to change the shape of the limiting ring 21 by the deformation of the limiting ring 21 and the MPP power tube body 1, so that the limiting ring 21 can be inserted into the inner groove of the limiting sleeve 22, and then due to the mutual resistance of the limiting ring 21 and the inner wall of the limiting sleeve 22, the limiting sleeve 22 is stably sleeved on the limiting ring 21, then the limiting ring 21 on the other end of the other MPP power tube body 1 is inserted into the other inner groove of the limiting sleeve 22, so that the two MPP power tube bodies 1 are more stably connected together, according to the above-mentioned operation, the operator can connect the corresponding number of MPP power tube bodies 1 according to the needs, so as to form the MPP power tube with the required length, so as to meet the use demand of the MPP power tube;
[0038] After the MPP power tube is assembled, the operator directly inserts the wire into the MPP power tube to complete the installation of the wire in the MPP power tube, and due to the support and limitation of the elastic sleeve 32 on the wire, the wire is relatively stable at the central position in the MPP power tube. When the wire bursts at a part of the position, the impact force generated will impact on the elastic sleeve 32, and the elastic sleeve 32 will deform adaptively through the compression of the internal gas, so as to offset the impact force generated when the wire bursts through the thrust of the internal gas of the elastic sleeve 32 on the inner wall of the elastic sleeve 32, so that the pipe wall of the MPP power tube body 1 will only bear a small impact force, and the constraint and limitation of the reinforcing rib 4 on the pipe wall of the MPP power tube body 1 will make the pipe wall of the MPP power tube body 1 almost not damaged due to a large impact force;
[0039] When the MPP power tube is subjected to external force, due to the thin pipe wall of the MPP power tube body 1, the pipe wall of the MPP power tube and the reinforcing rib 4 can easily deform to a certain extent, and the mutual resistance of the elastic sleeve 32 can also make the parts of the elastic sleeve 32 deform adaptively, so that the MPP power tube body 1 can deform when subjected to external force, and the external impact force on the MPP power tube can be released, thereby avoiding damage to the pipe wall of the MPP power tube. After the external force on the MPP power tube disappears, the MPP power tube quickly deforms and resets due to the pushing of the elastic sleeve 32 on the pipe wall of the MPP power tube body 1 when the elastic sleeve 32 resets;
[0040] When the MPP power tube is damaged due to the gnawing of animals such as rats or insects, the epoxy glue in the elastic strip is sprayed out, and due to the interception of the asbestos pad 31, the epoxy glue will not completely flow out of the MPP power tube. The hole on the MPP power tube is filled with epoxy glue, and due to the contact of the epoxy glue with the air, the epoxy glue quickly coagulates, thereby repairing the MPP power tube to a certain extent and prolonging the service life of the MPP power tube;
[0041] When the outer wall of the MPP power tube body 1 is damaged, the operator pulls the damaged MPP power tube body 1 and the adjacent MPP power tube body 1 to the two sides, so that a great resistance force is generated between the limiting ring 21 and the inner wall of the limiting sleeve 22, and then the opening of the limiting sleeve 22 is enlarged along the outer ring wall of the limiting ring 21, and the limiting ring 21 is pulled out of the limiting sleeve 22, so that the damaged MPP power tube body 1 can be disassembled, and then a new MPP power tube body 1 is replaced on the MPP power tube according to the above, so that the MPP power tube body 1 can be repaired.
[0042] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only the principles of the present application.
