Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, in particular to an MPP cable protection tube with an impact-resistant reinforcement rib structure. Background Art

[0002] MPP power pipes are available in standard and reinforced types. The reinforced type is further divided into trenchless and trenchless pipes. Trenchless MPP pipes are also known as MPP jacking pipes, MPP drag pipes, and MPP traction pipes. MPP power pipes are also known as MPP cable pipes and MPP power cable protection pipes. They are primarily made of PP powder (modified polypropylene). Connections are made by hot-melt welding with a welder. The weld point is around 200°C and should not exceed 220°C. Once the temperature is reached, the two ends can be butted together. (Because MPP pipes are connected by hot-melt welding, poor welds can damage cables or even flatten them. Therefore, MPP power pipes must be made from new material.) Modified polypropylene (MPP) power pipes are resistant to high temperatures and external pressures and are suitable for high-voltage transmission line and cable conduit applications above 10 kV.

[0003] At present, the connection method of MPP cable protection tubes is hot-melt welding with a welding machine. The welding point is around 200 degrees and cannot exceed 220 degrees. When the temperature is reached, the two ends can be butt-jointed. Even if the welding is perfect, the protection ability of the MPP cable protection tube at the interface will be reduced. When the interface is impacted by external force, the MPP cable protection tube is prone to rupture. In view of this, we propose an MPP cable protection tube with an impact-resistant reinforcement rib structure. Utility Model Content

[0004] The purpose of the present utility model is to provide an MPP cable protection tube with an impact-resistant reinforcement rib structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides an MPP cable protection tube with an impact-resistant reinforcement rib structure, including a fixed plate 1, wherein the front and rear sides of the bottom of the fixed plate 1 are fixedly connected to sliders, and the slider is a "T"-shaped structure. A fixed plate 2 is slidably connected below the fixed plate 1, and the front and rear sides of the upper surface of the fixed plate 2 are provided with sliding grooves, and the sliding grooves correspond to the sliders. The bottom center of the fixed plate 1 and the top center of the fixed plate 2 are provided with semicircular grooves, and the grooves correspond to each other up and down.

[0006] As a further improvement of the present technical solution, the fixed plate one and the fixed plate two are both cavities, and the inner cavities of the fixed plate one and the fixed plate two are fixedly connected with multiple support plates, and the multiple support plates are staggeredly distributed in the cavity, and the support plates and the inner cavity form multiple "triangle" structures.

[0007] As a further improvement of the present technical solution, constant temperature cotton is filled between the multiple support plates and between the support plates and the inner cavity.

[0008] As a further improvement of the present technical solution, a fixed plate extends out from the left side of the slider, a card slot is provided at the front end of the left side of the slider, the card slot is slidably connected to a card plate, and the card plate is a "T"-shaped structure.

[0009] As a further improvement of the present technical solution, the left and right ends of the groove are fixedly connected with rubber pads, and the rubber pads fit perfectly with the MPP cable protection tube.

[0010] As a further improvement of the present technical solution, the top of the fixing plate 1 and the bottom of the fixing plate 2 are both fixedly connected with arc covers.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The MPP cable protection tube with an impact-resistant reinforcement rib structure protects the interface of the MPP cable protection tube by adding a fixing plate 1 and a fixing plate 2 at the interface of the MPP cable protection tube. When the interface of the MPP cable protection tube is impacted, the arc cover performs a first force distribution of the impact force, and the support plates in the cavities of the fixing plates 1 and 2 perform a second force distribution, thereby minimizing the impact force on the interface of the MPP cable protection tube and protecting it.

[0021] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] MPP power pipes are divided into ordinary and reinforced types. The reinforced type is further divided into trenchless pipes and trenchless pipes. The so-called trenchless MPP pipe is also called MPP jacking pipe, MPP drag pipe, and MPP traction pipe. MPP power pipes are also called MPP cable pipes and MPP power cable protection pipes. The raw material is PP powder (modified polypropylene). The connection method is hot-melt welding with a welding machine. The welding point is around 200 degrees and cannot exceed 220 degrees. When the temperature is reached, the two ends can be butt-jointed. (Because the connection method of MPP pipes is hot-melt welding, poor welding joints will damage the cables or may flatten them, so MPP power pipes must be made of new materials). Modified polypropylene (MPP) power pipes are resistant to high temperatures and external pressures and are suitable for high-voltage transmission line cable conduit pipes above 10KV. Please refer to Figure 1-Figure 4 As shown, the utility model provides an MPP cable protection tube with an impact-resistant reinforcement rib structure, including a fixed plate 1, and a slider 11 is fixedly connected to the front and rear sides of the bottom of the fixed plate 1. The slider 11 is a "T"-shaped structure. The "T"-shaped structure can not only slide, but also can be clamped. A fixed plate 2 is slidably connected to the bottom of the fixed plate 1, and a sliding groove 23 is provided on the front and rear sides of the upper surface of the fixed plate 2. The sliding groove 23 is also a "T"-shaped structure. The sliding groove 23 corresponds to the slider 11. A semicircular groove 21 is provided at the bottom center of the fixed plate 1 and the top center of the fixed plate 2. The grooves 21 correspond to each other up and down, and the grooves 21 correspond to the MPP cable protection tube.

[0023] The improvement of this embodiment is that:

[0024] Taking into account that after the MPP cable protection tube is welded, the protection ability of the MPP cable protection tube at the interface to the cable is reduced, and when the interface is impacted by external force, the MPP cable protection tube is prone to rupture. Therefore, the front and rear sides of the bottom of the fixed plate 1 are fixedly connected with sliders 11. The slider 11 is a "T"-shaped structure. The "T"-shaped structure can not only slide, but also can be snapped. The fixed plate 2 is slidably connected below the fixed plate 1. The front and rear sides of the upper surface of the fixed plate 2 are provided with sliding grooves 23. The sliding grooves 23 are also a "T"-shaped structure. The sliding grooves 23 correspond to the slider 11. By sliding the slider 11 in the sliding grooves 23, the fixed plate 1 and the fixed plate 2 can be perfectly fitted together, thereby protecting the interface of the MPP cable protection tube between the fixed plate 1 and the fixed plate 2.

[0025] In order to disperse the impact force received by the fixing plate 1 and the fixing plate 2 2, the fixing plate 1 and the fixing plate 2 2 are both cavities, and the inner cavities of the fixing plate 1 and the fixing plate 2 2 are fixedly connected with multiple support plates 13. The multiple support plates 13 are staggered in the cavity, and the support plates 13 and the inner cavity form multiple "triangle" structures. The staggered distribution of the multiple support plates 13 disperses the impact force received by the fixing plate 1 and the fixing plate 2 2, thereby protecting the interface of the MPP cable protection tube.

[0026] Considering that the interface of the MPP cable protection tube is easily affected by temperature and may break, constant temperature cotton 14 is filled between multiple support plates 13 and between the support plates 13 and the inner cavity. The constant temperature cotton 14 can ensure that the temperature inside the fixing plate 1 and the fixing plate 2 2 is constant, thereby protecting the interface of the MPP cable protection tube from the influence of temperature factors.

[0027] In order to ensure that the fixed plate 1 and the fixed plate 2 2 can be well fixed after the sliding connection, the left side of the slider 11 extends out of the fixed plate 1, and a slot 15 is provided at the front end of the left side of the slider 11. The slot 15 is slidably connected with the card plate 12, and the card plate 12 is a "T"-shaped structure. When the fixed plate 1 and the fixed plate 2 2 are aligned, the card plate 12 slides in the slot 15 to limit and fix the fixed plate 1, thereby ensuring that the fixed plate 1 and the fixed plate 2 2 will not slide.

[0028] Taking into account the impact of humidity on the interface of the MPP cable protection tube, rubber pads 22 are fixedly connected to the left and right ends of the groove 21. The rubber pads 22 fit tightly with the MPP cable protection tube. The rubber pads 22 have good waterproof properties and can ensure that the environment between the fixing plate 1 and the fixing plate 2 2 is relatively dry.

[0029] In order to enable the device to withstand stronger impact force, the top of the fixed plate 1 and the bottom of the fixed plate 2 2 are fixedly connected with an arc cover 3. The arc cover 3 has an obvious force distribution effect, thereby achieving the first force distribution of the impact force.

[0030] In summary, the working principle of this solution is as follows:

[0031] When the MPP cable protection tube with the impact-resistant reinforcement rib structure is in use, the fixing plate 1 and the fixing plate 2 2 are respectively placed above and below the interface of the MPP cable protection tube, and the slider 11 of the fixing plate 1 is aligned with the slide groove 23 of the fixing plate 2, and the slider 11 is allowed to slide in the slide groove 23. When the fixing plate 1 and the fixing plate 2 are aligned, the clamping plate 12 is allowed to slide in the clamping groove 15 to limit and fix the fixing plate 1, thereby ensuring that the fixing plate 1 and the fixing plate 2 will not slide. When the interface of the MPP cable protection tube is subjected to impact, When struck, since the arc cover 3 has an obvious force distribution effect, the arc cover 3 will perform the first force distribution on the impact force. When the dispersed impact force reaches the fixed plate 1 and the fixed plate 2 2, multiple support plates 13 are staggered in the cavity. The support plates 13 and the inner cavity form multiple "triangle" structures. The staggered distribution of multiple support plates 13 disperses the impact force received by the fixed plate 1 and the fixed plate 2 2 for a second time, thereby minimizing the impact force received at the interface of the MPP cable protection tube and providing good protection for the interface of the MPP cable protection tube.

The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
