Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and in particular to a pre-buried cable bracket for laying cables. Background Art

[0002] In power construction, cables are usually placed in cable trenches or tunnels. Cable supports are installed on the trench walls or tunnel sidewalls to support and fix the cables in layers to ensure a safe distance and heat dissipation effect. Common types include pre-buried, plug-in, bolted, and assembled types. Pre-buried supports are fixedly connected to structural steel bars or other components before the trench sidewalls are cast. After casting, the ends of the supports are embedded in the trench wall, thus providing good stability. In some power construction projects, to address the problem of difficulty in replacing damaged pre-buried supports, they are designed as a two-part structure consisting of a pre-buried frame and a support body to enable quick replacement.

[0003] However, when the existing pre-buried bracket relies on the overall ventilation and heat dissipation of the cable trench, the heat exchange efficiency in the downstream area far from the air outlet is reduced due to the air flow absorbing the upstream heat, which hinders the heat dissipation of the downstream cable section and causes heat accumulation problems.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Please refer to Figures 1 to 9 , an embodiment of the present invention provides a pre-buried cable support for laying cables, comprising:

[0042] The heat dissipation mechanism 3 includes a main channel 31 extending in a first direction, a plurality of branch channels 32 arranged at the bottom end of the main channel 31 along the first direction, each branch channel 32 extending in a second direction, each branch channel 32 and the main channel 31 having a front end and a rear end along a third direction, a plurality of air intake pipes 34 connected to the main channel 31 arranged at the front end of the main channel 31 along the first direction, and a plurality of pre-buried frames 2 connected to the corresponding branch channels 32 provided at the front end of each branch channel 32 along the second direction. The first direction, the second direction and the third direction are perpendicular to each other; wherein, the first direction is Figure 1 The left and right directions in the second direction are Figure 1 The up and down directions in the third direction are Figure 1 the front-back direction in the

[0043] Several bracket bodies 1 include a mounting frame 14 provided inside the embedded frame 2 and connected to the branch channel 32, the mounting frame 14 is provided with a support plate 12 for carrying cables on the side away from the branch channel 32, and the mounting frame 14 is provided with a one-way airflow component 16 connected to the inside of the mounting frame 14 at the end away from the branch channel 32; wherein, one end of the mounting frame 14 is provided with an intermediate plate 11, the intermediate plate 11 and the embedded frame 2 are detachably connected by threads, the support plate 12 is provided in the middle of the intermediate plate 11, and a rib assembly 13 is provided at its bottom end, the rib assembly 13 is used to strengthen the support strength of the support plate 12, optionally, reference Figure 5 , the rib assembly 13 includes a main triangular rib, and auxiliary triangular ribs provided on both sides of the main triangular rib;

[0044] The heat dissipation mechanism 3 also includes a driving unit arranged inside the main channel 31, which is used to drive the external airflow to flow through the air inlet pipe 34, the main channel 31, the branch channel 32 and the mounting frame 14 in sequence, and finally flow out along the third direction toward the top of the support plate 12 through the one-way airflow component 16.

[0045] like Figure 1 and Figure 2 As shown, the airflow in the cable trench can be introduced into the main channel 31 through the driving part, and then radiated to the corresponding bracket body 1 through the branch channel 32 and the one-way airflow component 16, thereby realizing targeted airflow blowing of the cables on the bracket body 1, solving the problem of heat dissipation obstruction and heat accumulation in the downstream cable section in the prior art; optionally, the one-way airflow component 16 can use a one-way valve.

[0046] In some embodiments, the driving unit includes a first partition 33 arranged in the middle of the main channel 31 and extending along the first direction. One end of the first partition 33 along the first direction is connected to the inner wall of the main channel 31, and a fan 315 is provided between the other end and the inner wall of the main channel 31. There is an air inlet cavity above the first partition 33, and an air supply cavity below the first partition 33. The air inlet pipe 34 is connected to the air inlet cavity, and the branch channel 32 is connected to the air supply cavity.

[0047] like Figure 2 As shown, the fan 315 draws the gas in the cable trench into the air inlet cavity through the air inlet pipe 34, and then disperses the air flow into each branch channel 32 through the air supply cavity, thereby achieving the purpose of driving the gas circulation flow and ensuring long-term effective gas flow and heat dissipation.

[0048] In some embodiments, the heat dissipation mechanism 3 further includes a grounded heat exchange assembly, which includes a bottom plate 310 disposed at the bottom end of the branch channel 32. A third partition plate 39 extending in the second direction is disposed in the middle of the bottom plate 310. The third partition plate 39 divides the branch channel 32 into a downflow airway and an upflow airway arranged in the first direction. A U-shaped connecting pipe 311 is disposed at the bottom end of the bottom plate 310. Heat exchange fins 312 are disposed on the side surface of the U-shaped connecting pipe 311. The two ends of the U-shaped connecting pipe 311 are respectively connected to the bottom of the downflow airway and the bottom of the upflow airway.

[0049] A plurality of second partitions 38 are arranged along the first direction at the bottom end of the first partition 33 , and the bottom end of the second partition 38 is closed and connected to the top end of the third partition 39 .

[0050] like Figures 2 to 4 As shown, the airflow entering the air inlet cavity is blocked by the second partition 38 and the third partition 39, and will first enter the downflow airway of the corresponding branch channel 32, pass through the U-shaped connecting pipe 311, and then enter the upflow airway of the branch channel 32, and then flow back to the inside of the air inlet cavity, and so on, to achieve the airflow movement of each branch channel 32. During the movement, the airflow can not only exchange heat with the concrete on both sides of the branch channel 32, but also exchange heat with the soil through the U-shaped connecting pipe 311, so that each time it passes through the branch channel 3 2 can be simply cooled, and the airflow ejected by the one-way airflow component 16 can be better exchanged with the cable, avoiding the problem of heat accumulation caused by continuously sucking the airflow in the cable trench through the air inlet pipe 34; further, a cross plate 15 is provided inside the mounting frame 14, and one end of the cross plate 15 is closed and connected to the surface of the third partition plate 39; avoiding the downward airway and the upward airway from being connected in the middle, ensuring that the downward airway and the upward airway can only maintain airflow through the U-shaped connecting pipe 311, thereby ensuring the stability of the airflow direction.

[0051] In some embodiments, the heat exchange fins 312 extend upwardly along a first direction, and a triangular plug 313 is provided at the bottom end of the U-shaped connecting tube 311. The triangular plug 313 has a sharp corner away from the end of the U-shaped connecting tube 311; Figure 4 As shown, the triangular plug block 313 and the upwardly extending heat exchange fins 312 facilitate the stable insertion of the U-shaped connecting pipe 311 into the soil, and the upwardly extending heat exchange fins 312 can also initially maintain the stability of the branch channel 32 and reduce its shaking.

[0052] In some embodiments, the air inlet pipe 34 is threadedly connected to an internal threaded pipe 35 away from the main channel 31, a barrier ring 36 is provided in the middle of the internal threaded pipe 35, and a filter 37 is provided between the barrier ring 36 and the end of the air inlet pipe 34 away from the main channel 31; Figure 3 As shown, the gas in the cable trench will pass through the filter 37 and enter the main channel 31 along the inside of the air inlet pipe 34, reducing the dust from entering the main channel 31 and avoiding damage to the fan 315 or blockage of the one-way airflow component 16 caused by dust. In addition, by separating the internal threaded tube 35, the filter 37 can be removed for replacement or cleaning.

[0053] In some embodiments, a positioning frame 314 is provided at the bottom end of the main channel 31 corresponding to each branch channel 32. The embedded cable bracket further includes a plurality of channel leveling mechanisms corresponding to each branch channel 32. The channel leveling mechanisms are used to adjust the corresponding branch channel 32 to maintain a vertical state and be inserted into the positioning frame 314.

[0054] like Figure 1 、 Figure 2 and Figure 4 As shown, the branch channels 32 are inserted into the soil through the U-shaped connecting tube 311, the triangular plug block 313 and the heat exchange fins 312 extending upwardly. These branch channels 32 are arranged according to the spacing between the positioning frames 314. By adjusting the branch channels 32 to maintain a vertical state, the user can place the suspended main channel 31 above each branch channel 32, and insert the top side of the branch channel 32 into the positioning frame 314 to achieve rapid alignment and installation, thereby improving the convenience and accuracy of installation.

[0055] In some embodiments, the channel leveling mechanism comprises:

[0056] The leveling detection assembly 5 includes a plurality of detection bars 51 provided on the outer wall of the branch channel 32 and extending along the second direction. A connecting rope 54 is detachably mounted on one side of the detection bar 51, and a conical counterweight 55 is provided at the bottom end of the connecting rope 54.

[0057] The leveling adjustment assembly 6 includes a plurality of embedded blocks 61 that penetrate the bottom plate 310 and are evenly arranged around the branch channel 32. An adjustment plate 65 is provided below the embedded blocks 61. An adjustment bolt 63 is threadedly connected to the middle of the top of the embedded blocks 61.

[0058] Among them, such as Figure 4 As shown, each detection straight bar 51 is provided with a mounting sleeve 52 at the top, and a plug post 53 is detachably inserted in the middle of the mounting sleeve 52. The top of the connecting rope 54 is tied to the middle of the plug post 53 to achieve detachable installation of the connecting rope 54. The plug post 53 is installed inside each mounting sleeve 52 and aligned with the corresponding detection straight bar 51. If the connecting rope 54 is parallel to the detection straight bar 51, the adjustment is complete.

[0059] In addition, if Figure 6 As shown, an installation cavity 62 is provided inside the embedded block 61, and connecting springs 64 are provided on both sides of the adjusting bolt 63 at the top of the internal top of the installing cavity 62. The bottom end of the connecting spring 64 is connected to the top surface of the adjusting plate 65, so that the adjusting plate 65 can be maintained at the bottom end of the embedded block 61 when it is not driven by the adjusting bolt 63, and will not interfere with subsequent adjustments. When adjustment is needed, by rotating the adjusting bolt 63, under the action of the thread, the adjusting bolt 63 moves downward and pushes the adjusting plate 65 downward, thereby realizing a slight swing of the branch channel 32 with the base plate 310 as the reference, thereby achieving the purpose of adjustment.

[0060] In some embodiments, the embedded cable support further includes a plurality of first balancing mechanisms 4 disposed on the support plate 12 and arranged along the third direction. The first balancing mechanisms 4 are used to clamp the cable and keep the cable extending in the horizontal direction. Figure 4 and Figure 8 As shown, multiple first balancing mechanisms 4 can not only ensure that each cable is separated and independent from each other, ensure the stability of each cable and prevent it from shaking randomly, but also the cables extend in the horizontal direction, ensuring that there will be no oblique resistance after pulling the cables, thereby improving the convenience of pulling the cables when laying.

[0061] In some embodiments, the first balancing mechanism 4 includes:

[0062] The lower adjustment portion includes a mounting base plate 41 provided on the support plate 12. A movable plate 44 is rotatably connected to the mounting base plate 41 via a hinge seat 42. The axis of the rotation axis of the hinge seat 42 extends in the third direction. Buffer springs 43 are provided at both ends of the bottom surface of the movable plate 44 along the first direction. The bottom ends of the buffer springs 43 are connected to the mounting base plate 41.

[0063] The two upper adjustment parts are arranged at both ends of the top surface of the movable plate 44 along the first direction, and include two rotatable clamping rings 49. The axis extension direction of the two clamping rings 49 is the third direction. A plurality of clamping springs 412 are provided between the two clamping rings 49.

[0064] like Figure 4 、 Figure 8 and Figure 9 As shown, when the cable is placed between the two upper adjusting parts, the two clamping rings 49 of the same upper adjusting part are close to each other under the action of the clamping spring 412, which fails to achieve the purpose of clamping the cable. Moreover, because the two clamping rings 49 can rotate, the clamping rings 49 will be driven to rotate synchronously when the cable is dragged, thereby ensuring the separation of the cables and the stable dragging of a single cable.

[0065] Furthermore, since the two upper adjustment parts are arranged at the two ends of the top surface of the movable plate 44 along the first direction, the movable plate 44 can swing around the connecting axis of the hinge seat 42, thereby ensuring that the cable remains in a horizontal state under the action of gravity, which is convenient for dragging the cable, and a buffer spring 43 is provided to prevent the movable plate 44 from being excessively tilted, making it difficult to pull the cable.

[0066] In some embodiments, the upper adjustment portion further includes a rotatable limiting sleeve 47, the axis of which extends in the third direction. A plurality of limiting grooves 48 are disposed around the surface of the limiting sleeve 47. The inner walls of the two clamping rings 49 are provided with limiting sliders 410 that can move along the limiting grooves 48. Each clamping spring 412 is disposed in the corresponding limiting groove 48 and has its ends connected to the limiting sliders 410 of the two clamping rings 49.

[0067] like Figure 4 、 Figure 8 and Figure 9 As shown, the upper adjustment portion includes shaft seats 45 provided at both ends of the movable plate 44 along the third direction, and a guide shaft 46 is rotatably connected between the shaft seats 45. A limiting sleeve 47 is sleeved on the middle of the guide shaft 46 to ensure the stable rotation of the limiting sleeve 47 and the clamping ring 49; in addition, the installation of the clamping ring 49 is achieved by the limiting sleeve 47, and when the limiting slider 410 moves along the limiting groove 48, it is ensured that the two clamping rings 49 can move stably when approaching each other, thereby preventing the clamping ring 49 from deflecting relative to the limiting sleeve 47. Furthermore, the clamping spring 412 located in the limiting slide groove 48 also improves the structural strength of the clamping spring 412, ensuring its stable stretching and contraction. Furthermore, the two clamping rings 49 are close to each other and are provided with clamping inclined surfaces 411 on the end surfaces. A first angle is formed between the clamping inclined surfaces 411 and the axis of the guide shaft 46. The openings of the two first angles are both set to the side away from each other. The static friction force of the clamping inclined surfaces 411 against the cable surface is used to clamp the cable, which will not interfere with the removal and dragging of the cable.

[0068] In some embodiments, as Figure 7 As shown, the one-way airflow component 16 is divided into two groups, the upper and lower groups. The airflow blown out by the upper group contacts the upper surface of the cable. Because the guide shaft 46 and the clamping ring 49 will lift the cable, the airflow blown out by the lower group can contact the lower surface of the cable, thereby fully improving the heat exchange efficiency.

[0069] During the installation process: first, after the bottom surface of the cable trench is poured, the branch channels 32 are arranged along both sides of the bottom surface of the cable trench according to the spacing between the positioning frames 314;

[0070] When laying a single branch channel 32, first insert the U-shaped connecting pipe 311 stably into the soil through the triangular plug block 313 and the heat exchange fins 312 extending obliquely upward, and the heat exchange fins 312 extending obliquely upward can also initially maintain the stability of the branch channel 32 and reduce its shaking. Then install the plug post 53 into the interior of each mounting sleeve 52 and the corresponding detection straight bar 51. If the connecting rope 54 is not parallel to the detection straight bar 51, select the corresponding embedding block 61 according to the inclination direction of the branch channel 32, rotate the adjusting bolt 63, and under the action of the thread, the adjusting bolt 63 moves downward and pushes the adjusting plate 65 downward, thereby achieving a slight swing of the branch channel 32 with the bottom plate 310 as the reference, thereby achieving the purpose of adjustment. Finally, when the plug post 53 is inserted into any mounting sleeve 52, the connecting rope 54 and the detection straight bar 51 remain parallel, and the adjustment is completed.

[0071] Then, through the lifted main channel 31, it falls above each branch channel 32 and is inserted into the positioning frame 314 through the top side of the branch channel 32 to achieve rapid alignment and installation, thereby improving the convenience and accuracy of installation. Then, a casting plate is set up, holes for the embedded frame 2 and the air inlet pipe 34 are reserved, and concrete is poured into the space formed by the casting plate to finally form the side wall of the cable trench.
