Description

Technical Field

[0001] The invention relates to the technical field of cable protection tubes, and in particular to an MPP cable protection tube with strong heat dissipation. Background Art

[0002] MPP power pipe, also known as MPP cable pipe and MPP cable protection pipe, is a protective pipe with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged or disturbed by the magnetic field.

[0003] However, the survey found that the existing MPP cable protection tubes generally have poor heat dissipation, especially in the following two situations, they often have insufficient coping capabilities: 1. Multiple power cables share one cable protection tube: In this case, when the cables are working, the heat generated by the large number of cables can easily cause the local temperature to be too high, which will reduce the safety of the cable use and the service life of the cable protection tube; 2. Separate protection of high-power and high-load power cables: In this case, the heat emitted by the cable in the cable protection tube cannot be dissipated in time, causing the cable temperature to rise and the power transmission capacity to decrease. In the long run, it will also cause damage to the cable and the cable protection tube.

[0004] In order to solve the above problems, a Chinese utility model patent with announcement number CN211126937U and name of a new type of heat dissipation MPP cable protection tube is disclosed. The disclosure scheme is as follows: it includes a tube body, a heat dissipation protection device is arranged in the tube body cavity, and the heat dissipation protection device is composed of a protection plate, a heat dissipation column, a fixed plate, a movable column and a rubber ball. There are two protection plates, and the protection plate is an arc plate. Heat dissipation holes are opened on the outer walls of the two protection plates. The heat dissipation column is fixedly installed on the outer wall of the protection plate. The fixed plate is a hollow rectangular plate. There are two fixed plates, and the two fixed plates are respectively fixedly installed at the upper and lower ends of the tube body cavity. A protrusion is arranged at one end of the movable column, and the protruding ends of the two movable columns are both engaged in the corresponding fixed plate cavity. For this new type of heat dissipation MPP cable protection tube, when the cable transmits electricity, the space in the tube body cavity provides a place for heat dissipation for the heat generated by the cable during operation, thereby improving the heat dissipation efficiency and avoiding the problem that the cable body is completely wrapped in the tube body cavity and cannot be timely dissipated and transmitted.

[0005] However, although the above-mentioned patent scheme can play a certain role in heat dissipation, the heat needs to be dissipated in the tube body cavity through the heat dissipation protection device first, and then dissipated through the tube body, which makes the heat dissipation efficiency low. Once the cable runs at high temperature or heats up quickly, it is often unable to cope well; in addition, the tube body in the above-mentioned patent scheme is formed in one piece rather than connected in parts. When installing the cable protection tube, the cable needs to be inserted from one end and out from the other end to complete, which makes it complicated to solve the problems of installing and rectifying existing cables with cable protection tubes and replacing expired cable protection tubes.

[0006] Therefore, it is necessary to invent an MPP cable protection tube which has high heat dissipation efficiency and is easy to install and replace. Summary of the invention

[0007] In view of the above problems, the present invention proposes an MPP cable protection tube with strong heat dissipation, and the technical solution adopted is as follows: A strong heat dissipation MPP cable protection tube, characterized by comprising a heat dissipation mechanism which is installed in a split manner and has heat-conducting fins distributed on the inner wall for close contact with the cable, an MPP protection tube mechanism which is installed in a split manner outside the heat dissipation mechanism and has a gap between the heat dissipation mechanism and the MPP protection tube mechanism, and an air collection mechanism installed on the heat dissipation mechanism and the MPP protection tube mechanism; The wind collecting mechanism includes wind collecting components distributed from at least one end of the heat dissipation mechanism to the middle, and a driving control component for driving the wind collecting components to open and close; wherein, the wind collecting components located at the end of the heat dissipation mechanism are used to concentrate the wind on the above-mentioned heat-conducting fins, and the remaining wind collecting components are used to concentrate the wind on the gap between the MPP protection tube mechanism and the heat dissipation mechanism; the MPP protection tube mechanism is provided with a shelter at the position corresponding to the wind collecting components.

[0008] Furthermore, the wind collecting assembly includes support rods whose inner ends are rotatably mounted on the outer wall of the heat dissipation mechanism and are evenly distributed in an arc shape along the cross section of the heat dissipation mechanism, and tarpaulins mounted on all the support rods.

[0009] Furthermore, the drive control assembly includes an expansion slide which is elastically slidably installed on the outer surface of the heat dissipation mechanism along the axial direction and connected to the support rod through a pull rope, a limiting slide which is slidably installed on the MPP protection tube mechanism along the axial direction and intermittently acts on the support rod, a driving push rod which is installed on the MPP protection tube mechanism and the output end of which is connected to the limiting slide, a temperature sensor installed on the inner wall of the heat dissipation mechanism, and a controller for controlling the action of the driving push rod.

[0010] Furthermore, the support rod is provided with a control block for intermittently contacting the limiting slide.

[0011] Furthermore, the controller is provided with a receiving terminal for receiving weather information.

[0012] Furthermore, the heat dissipation mechanism comprises an upper heat dissipation pipe and a lower heat dissipation pipe which are installed in a split manner; the heat conduction fins and the temperature sensor are arranged on the inner wall of the upper heat dissipation pipe; and the air collecting assembly is arranged on the outer wall of the upper heat dissipation pipe.

[0013] Furthermore, the outer diameter of one end of the upper heat dissipation pipe corresponding to the wind collecting component is reduced in a two-step shape, and the wind collecting component located at the end of the heat dissipation mechanism is arranged on the second step.

[0014] Furthermore, the heat dissipation mechanism also includes a locking assembly for locking the upper heat dissipation tube and the lower heat dissipation tube; the locking assembly includes a locking slide sliding on the outer wall of the upper heat dissipation tube, a locking column fixedly arranged on the lower heat dissipation tube and having a through groove in the middle and lower part along the sliding direction of the locking slide, a strip-shaped limiting hole arranged on the locking slide and corresponding to the locking column, and an extrusion block for pushing the locking slide to slide; a through hole is arranged on the upper heat dissipation tube corresponding to the locking column.

[0015] Furthermore, the MPP protection tube mechanism includes an upper protection tube and a lower protection tube which are installed in a split manner and whose shapes match the upper heat dissipation tube and the lower heat dissipation tube respectively; the limiting slide and the driving push rod are arranged on the upper protection tube; the upper protection tube and the lower protection tube are locked by a sliding buckle.

[0016] Furthermore, the heat-conducting fins include limiting cavities distributed on the inner wall of the upper heat dissipation tube, and fins elastically and slidably mounted in the limiting cavities.

[0017] Since the present invention adopts the above technical solution, the present invention has the following advantages: 1. The present invention not only realizes the strong heat dissipation of the MPP cable protection tube through the matching design of the heat dissipation mechanism, the air collection mechanism and the MPP protection tube mechanism, but also solves the problem that it is difficult to install, modify and replace the cable protection tube of the existing cables.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0035] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "in", "out", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Embodiment 1:

[0036] This embodiment is implemented by taking the installation and rectification of cable protection tubes for exposed cables currently installed on the wall as an example. Figure 1-6 As shown in FIG9 , a strong heat dissipation MPP cable protection tube comprises a heat dissipation mechanism 1 which is installed in a split manner and has heat-conducting fins 1201 distributed on the inner wall for close contact with the cable, an MPP protection tube mechanism 3 which is installed in a split manner outside the heat dissipation mechanism 1 and has a gap between the heat dissipation mechanism 1 and the MPP protection tube mechanism 3, and an air collection mechanism 2 installed on the heat dissipation mechanism 1 and the MPP protection tube mechanism 3; in this embodiment, the heat dissipation mechanism 1 is made of a metal material with good thermal conductivity, such as copper material; As a specific implementation of this embodiment, Figure 7-8As shown, the heat dissipation mechanism 1 includes an upper heat dissipation tube 12 and a lower heat dissipation tube 11 which are installed in an upper and lower split manner; a heat-conducting fin 1201 is arranged on the inner wall of the upper heat dissipation tube 12; in order to facilitate the installation, rectification or replacement of the cable protection tube of the existing cable, the lower heat dissipation tube 11 adopts a flat arc design with connecting plates on both sides, and the upper heat dissipation tube 12 adopts a high-convex arc design with connecting plates on both sides, and the lower heat dissipation tube 11 and the upper heat dissipation tube 12 adopt a parent-child connection method (such a design can improve stability); the inner wall of the lower heat dissipation tube 11 and the end of the heat-conducting fin 1201 of the upper heat dissipation tube 12 together form a circle that can be in close contact with the cable; In order to further improve the installation tightness of the upper heat dissipation pipe 12 and the lower heat dissipation pipe 11, as Fig.10 As shown, the heat dissipation mechanism 1 also includes a locking assembly 13 for locking the upper heat dissipation tube 12 and the lower heat dissipation tube 11; the locking assembly 13 includes two locking slides 1301 that are symmetrical and slide axially on the outer wall of the upper heat dissipation tube 12, a locking column 1303 that is fixedly arranged on the lower heat dissipation tube 11 and has a through groove in the middle and lower part along the sliding direction of the locking slide 1301, a strip-shaped limiting hole 1301a that is arranged on each locking slide 1301 and corresponds to the locking column 1303, and an extrusion block 1302 that is slidably installed between the two locking slides 1301 and is used to push the locking slide 1301 to slide; wherein, a through hole is arranged on the upper heat dissipation tube 12 corresponding to the locking column 1303, and the strip-shaped limiting hole 1301a is key-shaped; a pair of arc-shaped protrusions are symmetrically arranged in the middle of the opposite sides of the two locking slides 1301, so that the extrusion block 1302 can separate the two locking slides 1301 outward; The steps of locking the upper heat dissipation tube 12 and the lower heat dissipation tube 11 are as follows: first, the two locking slides 1301 are slid toward each other and pressed against each other, and then the upper heat dissipation tube 12 and the lower heat dissipation tube 11 are buckled together through the locking column 1303, at which time the locking column 1303 passes through the large hole of the strip-shaped limiting hole 1301a; then, the extrusion block 1302 is pushed to the middle of the two arc-shaped protrusions, and the two locking slides 1301 are separated outwards, at which time the narrow strip hole of the strip-shaped limiting hole 1301a passes through the through groove of the locking column 1303, and the upper heat dissipation tube 12 and the lower heat dissipation tube 11 are locked; like Figure 18-19 As shown, the MPP protection tube mechanism 3 includes an upper protection tube 32 and a lower protection tube 31 which are installed in an upper and lower split manner and whose shapes match the upper heat dissipation tube 12 and the lower heat dissipation tube 11 respectively; the upper protection tube 32 and the lower protection tube 31 are locked by a sliding buckle 33; The installation steps of the heat dissipation mechanism 1 and the MPP protection tube mechanism 3 are as follows: The first step is to remove the section of the bare cable installed on the wall where the cable protection tube is to be installed; The second step is to fix the lower protection tube 31 to the wall by bolting or clamping; In the third step, the upper heat dissipation pipe 12 and the lower heat dissipation pipe 11 are fastened and installed on the outer surface of the cable through the locking assembly 13 to complete the installation of the heat dissipation mechanism 1; In the fourth step, the installed heat dissipation mechanism 1 is lifted and placed against the inner arc surface of the lower protective tube 31, and then the upper protective tube 32 is connected to the lower protective tube 31 and locked by sliding the buckle 33, thereby completing the installation of the heat dissipation mechanism 1 and the MPP protective tube mechanism 3.

[0037] As a specific implementation of this embodiment, Figure 14-16 As shown, in order to better adapt to the wind direction, the wind collecting mechanism 2 includes a driving control component and four wind collecting components 22; the four wind collecting components 22 are grouped in pairs, and are distributed from both ends of the upper heat dissipation pipe 12 to the middle with the middle cross section of the upper heat dissipation pipe 12 as the center plane and are symmetrically arranged. The two wind collecting components 22 located at the ends of the upper heat dissipation pipe 12 are used to concentrate the wind on the above-mentioned heat-conducting fins 1201, and the remaining two wind collecting components 22 are used to concentrate the wind on the gap between the MPP protection tube mechanism 3 and the heat dissipation mechanism 1; the position of the MPP protection tube mechanism 3 corresponding to the wind collecting component 22 is provided with a shelter; In order to reduce the influence of the wind collecting assembly 22 at the end of the upper heat dissipation pipe 12 on the wind collecting assembly 22 near the middle, as shown in FIG. Figure 7-8 As shown, the outer diameters of the ends of the upper heat dissipation pipe 12 are reduced in a two-step step shape, and the wind collecting components 22 located at the ends are arranged on the second step. In this way, during the wind collecting process, since the height of the wind collecting components 22 at the ends is lower than the wind collecting components 22 near the middle, the wind collecting effect of the wind collecting components 22 near the middle can be guaranteed to the greatest extent; Specifically, Figure 11-13 As shown in FIG. 17 , the wind collecting assembly 22 includes support rods 2201 rotatably mounted on the outer wall of the upper heat dissipation pipe 12 at the inner end and uniformly arranged in an arc shape along the cross section of the upper heat dissipation pipe 12 , and tarpaulins 2202 mounted on all the support rods 2201 ; The driving control assembly includes an opening slide 21, a limiting slide 23, a driving push rod 24, a temperature sensor 25 and a controller 26, wherein the opening slide 21, the limiting slide 23 and the driving push rod 24 each constitute a group of driving members, and in this embodiment, two groups of driving members are provided, and each group of driving members corresponds to two air collecting assemblies 22 located on one side of the middle cross section of the upper heat dissipation pipe 12; In each set of driving parts, the opening slide 21 is elastically slidably installed on the outer wall of the upper heat dissipation tube 12 near the middle through the return spring 2101, and is connected to all corresponding support rods 2201 through the pull rope 2102; the limiting slide 23 is slidably installed on the upper protection tube 32, and the driving push rod 24 is fixedly installed in the middle of the upper protection tube 32; The temperature sensor 25 is arranged on the inner wall of the upper heat dissipation tube 12, and the controller 26 is fixedly installed in the middle of the upper protection tube 32; the two sets of driving parts share the temperature sensor 25 and the controller 26; in this embodiment, in order to accurately detect the temperature of each section of the cable and ensure that each section of the cable can obtain strong heat dissipation, the temperature sensor 25 is installed on the inner wall of the upper heat dissipation tube 12 every 20-50 cm along the axial direction; In this embodiment, in order to better fold the tarpaulin 2202, a control block 2201a is provided in the middle of the support rod 2201; in order to be able to fold the wind collection component 22 in advance when the weather becomes bad, a receiving terminal for receiving weather information is provided in the controller 26; The operating principle of the drive control component is as follows: when the controller 26 detects that the temperature rises to the set value through any temperature sensor 25, the limit slide 23 in each set of drive parts is gradually separated from the control block 2201a under the pull of the drive push rod 24, and the pull rope 2102 moves upward to the middle of the heat dissipation pipe 12 along with the stretched slide 21 under the action of the return spring 2101. At this time, the support rod 2201 rotates upward and drives the tarpaulin 2202 to be stretched to form a wind collecting hood for collecting wind; when the controller 26 detects that the temperature drops to the set value through the temperature sensor 25 or receives the severe weather warning information through the receiving end, the limit slide 23 in each set of drive parts contacts the control block 2201a under the push of the drive push rod 24 and gradually completes the downward pressure. In this process, the support rod 2201 It rotates downward and drives the tarpaulin 2202 to fold. At the same time, the pull rope 2102 pulls the expansion slide 21 to move toward the end of the upper heat dissipation pipe 12. The reset spring 2101 completes energy storage during the sliding process of the expansion slide 21, preparing for the next opening of the wind collecting component 22 (it needs to be explained here that in order to adapt to the wind direction, the two sets of driving parts drive the wind collecting components 22 to unfold at the same time. When all the wind collecting components 22 are in the unfolded state and one side is intaken with wind, since the wind collecting components 22 driven by the two sets of driving parts are symmetrical, the wind collecting components 22 on the side that is not intaken with wind will neither block the heat dissipation of the thermal fins 1201 nor block the heat dissipation of the gap between the MPP protection tube mechanism 3 and the heat dissipation mechanism 1, and the impact on the surrounding wind speed is also relatively small).

[0038] It is also noted that if the present embodiment is installed in a relatively closed environment, the following measures can be taken: a fan is installed at a position opposite to one end of the MPP cable protection tube of the present embodiment, and the fan is electrically connected to the controller 26. When it is necessary to open the wind collecting component 22 for heat dissipation, the controller 26 turns on the fan at the same time to achieve strong heat dissipation. Embodiment 2:

[0039] This embodiment improves the heat conducting fin 1201 based on the first embodiment, specifically: Figure 20-21As shown, the heat-conducting fin 1201 includes a limiting cavity 1201a, a fin 1201b and a return spring 1201c. The limiting cavity 1201a is distributed on the inner wall of the upper heat dissipation tube 12, and the fin 1201b is elastically slidably installed in the limiting cavity 1201a through the return spring 1201c. When multiple power cables share one cable protection tube, due to the irregular outer circle formed, the fixedly installed thermal fins 1201 often cannot fully contact the outer circle formed by the multiple cables, resulting in poor heat dissipation effect. The design of this embodiment can solve this problem.

[0040] The other structures are the same as those in Embodiment 1 and will not be described in detail here. Embodiment three:

[0041] The difference between this embodiment and the first embodiment is that: Fig. 22 As shown, the air collecting mechanism 2 includes six air collecting components 22; the six air collecting components 22 are grouped in pairs, and are distributed from both ends of the upper heat dissipation pipe 12 to the middle with the middle cross-section of the upper heat dissipation pipe 12 as the center plane and are symmetrically arranged. The two air collecting components 22 located at the ends of the upper heat dissipation pipe 12 are used to concentrate the wind on the above-mentioned heat-conducting fins 1201, and the remaining four air collecting components 22 are used to concentrate the wind on the gap between the MPP protection tube mechanism 3 and the heat dissipation mechanism 1; the MPP protection tube mechanism 3 is provided with a shelter at the position corresponding to the air collecting component 22.
