Description

Technical Field

[0001] This application relates to the technical field of cable trench protection devices, and more particularly to a cable trench protection device. Background Technology

[0002] A published patent document (CN205039504U) discloses a protective device for cable trenches, including a safety cover corresponding to the cable trench. Below the safety cover is a protective isolation plate spaced apart from it, the width of which is smaller than the width of the corresponding cable trench. The safety cover has ventilation holes arranged within the isolation area of ​​the protective isolation plate. This cable trench protective device has a simple and reasonable structure, is easy and convenient to install, and provides good safety protection and ventilation / heat dissipation.

[0003] The above devices do not take into account the internal drainage of the cable trench and the impact of rainwater on the cable. In rainy weather, rainwater will directly wash over the cable, which may affect the use of the cable. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a protective device for cable trenches, which overcomes the deficiencies of existing technologies and aims to solve the problem that existing devices do not take into account the internal drainage of the cable trench and the impact of rainwater on the cables. In rainy weather, rainwater will directly wash over the cables, which may affect the use of the cables.

[0005] To achieve the above objectives, this application provides the following technical solution: a protective device for a cable trench, comprising a cable trench body, wherein multiple sets of sliding grooves are formed on both sides of the interior of the cable trench body, and multiple sets of cable fixing frames are installed inside the cable trench body. Each cable fixing frame includes two sets of cover plates, four sets of bearing plates, and a support frame. The two sets of cover plates are located on the upper sides of the support frame, and the four sets of bearing plates are installed on both sides of the support frame. The four sets of bearing plates are located below the two sets of cover plates. Float mechanisms are installed on both sides of the multiple sets of cable fixing frames. Each float mechanism includes a bottom float and an upper float. The bottom float is located below the upper float. A first fixing block is installed on one side of the upper float, and a sliding plate is installed on one side of the first fixing block. The sliding plate has a hollow hole inside and is slidably connected to the interior of the sliding groove.

[0006] By adopting the above technical solution and setting up a cable fixing frame, cables can be placed above multiple sets of support plates during use. In rainy weather, rainwater is first blocked by the shielding plates when it reaches the inside of the cable trench, and then falls directly to the bottom of the cable trench through both sides without contacting the cables. In heavy rain, the bottom and top floats provide buoyancy to the cable fixing frame, keeping the cables inside the frame away from the water surface, reducing contact with the water, and preventing short circuits. The sliding plates slide inside the sliding groove, making the cable fixing frame more stable when sliding up and down. The design of multiple sets of support plates also makes it convenient for workers to classify and place the cables inside the cable trench, avoiding interference. In normal weather, the shielding plates also protect the cables above the support plates from impacts from stones and other hard debris, preventing damage to the cable exterior and extending the cable's service life.

[0007] As a preferred technical solution of this application, a second fixing block is installed on the top of each of the multiple sets of sliding grooves, and a rotating rod is installed inside each of the multiple sets of sliding grooves. The rotating rod passes through the second fixing block and is rotatably connected to the second fixing block. A third fixing block is installed inside the sliding groove, and the third fixing block is threadedly connected to the bottom of the rotating rod.

[0008] By adopting the above technical solution and setting a second fixing block, the position of the second fixing block can be changed by rotating the rotating rod during use, thereby changing the position of the sliding plate. This allows the staff to easily adjust the height of the bottom of the cable fixing frame. In areas with frequent severe weather, the position of the third fixing block can be flexibly adjusted to limit the height between the cable fixing frame and the bottom of the cable trench, allowing water to be discharged better through the bottom of the cable trench, making the use of cables safer.

[0009] As a preferred technical solution of this application, the top of the cable trench is provided with a placement groove, the inside of the placement groove is equipped with a baffle, and the inside of the baffle is provided with multiple sets of ventilation openings.

[0010] By adopting the above technical solution and setting up placement slots, it is easier for workers to install the baffles. The ventilation openings can effectively improve the internal ventilation performance of the cable trench and help the cables inside the cable trench to dissipate heat.

[0011] As a preferred technical solution of this application, multiple cable placement slots are provided above the multiple sets of carrier plates, and protective plates are installed on the outer side of the multiple sets of carrier plates.

[0012] By adopting the above technical solution and setting up cable placement grooves, it is more convenient for workers to place cables. The protective plates can provide protection for both sides of the support plate, preventing debris from entering the support plate and damaging the cables.

[0013] As a preferred technical solution of this application, a drainage groove is provided at the bottom of the cable trench, and arc-shaped blocks are installed on both sides of the drainage groove.

[0014] By adopting the above technical solution and setting up drainage channels, the drainage performance of the cable trench can be improved. The arc-shaped blocks can make it easier for debris and water to enter the interior of the drainage channels, thereby improving drainage performance and making the cables safer.

[0015] As a preferred technical solution of this application, the top of the support frame is provided with a sleeve groove, and a slider is sleeved inside the sleeve groove. The top of the slider is fixedly connected to the bottom of the baffle.

[0016] By adopting the above technical solution and setting a slider, the vertical movement of the cable fixing bracket is more stable during use because the slider and the socket are interlocked. This also effectively prevents the cable fixing bracket from shifting position during use, thus improving the practicality of the device.

[0017] As a preferred technical solution of this application, the top of the baffle is provided with a mounting groove, and mounting holes are provided at the four corners of the mounting groove. A dustproof net is installed inside the mounting groove, and mounting screws are installed at the four corners of the dustproof net corresponding to the mounting holes.

[0018] By adopting the above technical solution and setting the installation slot, external dust and debris can be filtered during use. The installation screws make it easier for workers to install and remove the dustproof net.

[0019] As a preferred technical solution of this application, the bottom of the baffle is provided with multiple sets of fixing grooves, and the positions of the multiple sets of fixing grooves correspond to the positions of the multiple sets of rotating rods.

[0020] By adopting the above technical solution and setting a fixing groove, the position of the baffle can be restricted by the rotating rod during use, preventing it from shifting and improving the practicality of the device.

[0021] The beneficial effects of this application are:

[0022] 1. By setting up cable fixing brackets, cables can be placed above multiple sets of support plates during use. In rainy weather, rainwater is first blocked by the shielding plates before falling directly to the bottom of the cable trench through both sides, preventing contact with the cables. In heavy rain, the bottom and top floats provide buoyancy to the cable fixing brackets, keeping the cables inside away from the water surface and reducing contact with the water to prevent short circuits. The sliding plates slide inside the sliding grooves, making the cable fixing brackets more stable when sliding up and down. The design of multiple sets of support plates also facilitates the classification and placement of cables inside the cable trench by workers, avoiding interference. In normal weather, the shielding plates also protect the cables above the support plates from impacts from stones and other hard debris, preventing external damage to the cables and extending their service life.

[0023] 2. By setting a second fixing block, the position of the second fixing block can be changed by rotating the rotating rod during use, thereby changing the position of the sliding plate. This allows the staff to easily adjust the height of the bottom of the cable fixing frame. In areas with frequent severe weather, the position of the third fixing block can be flexibly adjusted to limit the height between the cable fixing frame and the bottom of the cable trench, allowing water to be discharged better through the bottom of the cable trench, making the use of cables safer.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-3 A protective device for a cable trench includes a cable trench body 1. Multiple sets of sliding grooves 101 are formed on both sides of the interior of the cable trench body 1. Multiple sets of cable fixing frames 2 are installed inside the cable trench body 1. Each cable fixing frame 2 includes two sets of shields 201, four sets of bearing plates 202, and a support frame 203. The two sets of shields 201 are located above the support frame 203 on both sides. The four sets of bearing plates 202 are installed on both sides of the support frame 203, and below the two sets of shields 201. A float mechanism 3 is installed on both sides of each set of cable fixing frames 2. The float mechanism 3 includes a bottom float 301 and an upper float 302. The bottom float 301 is located below the upper float 302. A first fixing block 303 is installed on one side of the upper float 302. A sliding plate 304 is installed on one side of the first fixing block 303. The sliding plate 304 has an internal hole. A second fixing block 104 is slidably connected to the interior of the sliding groove 101. The top of the cable trench 1 is provided with a placement groove 103, and a baffle 4 is installed inside the placement groove 103. Multiple ventilation openings 401 are provided inside the baffle 4.

[0032] By setting up the cable fixing bracket 2, cables can be placed above multiple sets of bearing plates 202 during use. In rainy weather, when rainwater reaches the inside of the cable trench 1, it will first be blocked by the shield 201, and then fall directly to the bottom of the cable trench 1 through both sides without contacting the cables. In heavy rain, the bottom float 301 and the upper float 302 can provide a certain buoyancy for the cable fixing bracket 2, keeping the cables inside the cable fixing bracket 2 away from the water surface, reducing contact with the water surface and preventing short circuits. The sliding plate 304 slides inside the sliding groove 101, making the cable fixing bracket 2 more stable when sliding up and down. The design of multiple sets of bearing plates 202 also makes it convenient for staff to classify and place the cables inside the cable trench 1, avoiding interference. In normal weather, the shield 201 can also protect the cables above the bearing plates 202 from the impact of stones and other hard debris, preventing damage to the cable exterior and extending the service life of the cables. By setting up the placement slot 103, it is easier for staff to install the baffle 4. The ventilation opening 401 can effectively improve the ventilation performance inside the cable trench 1 and effectively help the cables inside the cable trench 1 to dissipate heat.

[0033] Reference Figure 1Each of the multiple sliding grooves 101 has a second fixing block 104 installed on its top. A rotating rod 105 is installed inside each of the multiple sliding grooves 101, passing through and rotatably connecting to the second fixing block 104. A third fixing block 108 is installed inside each sliding groove 101, threadedly connected to the bottom of the rotating rod 105. Multiple cable placement slots 206 are provided above each of the multiple bearing plates 202, and protective plates 207 are installed on the outer sides of each of the multiple bearing plates 202. A sleeve groove 204 is provided on the top of the support frame 203, and a slider 205 is sleeved inside the sleeve groove 204. The top of the slider 205 is fixedly connected to the bottom of the baffle 4. By setting the second fixing block 104, the position of the third fixing block 108 can be changed by rotating the rotating rod 105 during use, thereby changing the position of the sliding plate 304. This design allows for convenient adjustment of the bottom height of the cable fixing bracket 2 by staff. In areas with frequent severe weather, the position of the third fixing block 108 can be flexibly adjusted to limit the height between the cable fixing bracket 2 and the bottom of the cable trench 1, allowing water to drain more effectively through the bottom of the cable trench 1, thus enhancing cable safety. The cable placement groove 206 makes cable placement more convenient for staff. The protective plate 207 provides protection for both sides of the support plate 202, preventing debris from entering the support plate 202 and damaging the cable. The slider 205, which interlocks with the socket groove 204, ensures stable vertical movement of the cable fixing bracket 2 and effectively prevents positional displacement, improving the device's practicality.

[0034] Reference Figure 1 The bottom of the cable trench 1 is provided with a drainage trough 106, and arc-shaped blocks 107 are installed on both sides of the drainage trough 106. By setting the drainage trough 106, the drainage performance of the cable trench 1 can be improved. The arc-shaped blocks 107 can make it easier for debris and water to enter the interior of the drainage trough 106, thereby improving drainage performance and making the cable safer. The top of the baffle 4 is provided with an installation groove 403, and installation holes 404 are provided at the four corners of the installation groove 403. A dustproof net 5 is installed inside the installation groove 403, and the four corners of the dustproof net 5 correspond to the installation holes 404. The device is equipped with mounting screws 501; by setting mounting grooves 403, external dust and debris can be filtered through 503 during use. The mounting screws 501 make it easier for workers to install and remove the dustproof net 5; multiple sets of fixing grooves 402 are opened at the bottom of the baffle 4, and the positions of the multiple sets of fixing grooves 402 correspond to the positions of multiple sets of rotating rods 105. By setting fixing grooves 402, the position of the baffle 4 can be restricted by the rotating rods 105 during use, so that it will not shift during use, thus improving the practicality of the device.

[0035] Working Principle: By setting up the cable fixing bracket 2, cables can be placed above multiple sets of support plates 202 during use. In rainy weather, when rainwater reaches the inside of the cable trench 1, it will first be blocked by the shielding plate 201, and then fall directly to the bottom of the cable trench 1 through both sides, without contacting the cables. In heavy rain, the bottom float 301 and the upper float 302 can provide a certain buoyancy for the cable fixing bracket 2, keeping the cables inside the cable fixing bracket 2 away from the water surface, reducing contact with the water surface and preventing short circuits. The sliding plate 304 slides inside the sliding groove 101, making the cable fixing bracket 2 more stable when sliding up and down. The design of multiple sets of support plates 202 also facilitates the operation of personnel to access the cables inside the cable trench 1. The cables are placed in categories to avoid interference. In normal weather, the shield 201 can also protect the cables above the support plate 202 from impacts by stones and other hard debris, preventing damage to the cables and extending their service life. By setting the second fixing block 104, the position of the third fixing block 108 can be changed by rotating the rotating rod 105 during use, thereby changing the position of the sliding plate 304. This allows the staff to easily adjust the height of the bottom of the cable fixing frame 2. In areas with frequent severe weather, the position of the third fixing block 108 can be flexibly adjusted to limit the height between the cable fixing frame 2 and the bottom of the cable trench 1, allowing water to drain better through the bottom of the cable trench 1, making the use of cables safer.

[0036] The placement slot 103 makes it easier for workers to install the baffle 4. The ventilation opening 401 effectively improves the ventilation performance inside the cable trench 1 and helps the cables inside the cable trench 1 to dissipate heat. The cable placement slot 206 makes it easier for workers to place cables. The protective plate 207 provides protection for both sides of the support plate 202 to prevent debris from entering the support plate 202 and damaging the cables.

[0037] Meanwhile, by setting up the drainage trough 106, the drainage performance of the cable trench 1 can be improved. The arc-shaped block 107 can make it easier for debris and water to enter the interior of the drainage trough 106, thereby improving the drainage performance and making the cable safer.

[0038] In addition, by setting the slider 205, the cable fixing bracket 2 can move up and down more stably during use because the slider 205 and the socket 204 are interlocked, and the position of the cable fixing bracket 2 can be effectively prevented from shifting during use, thus improving the practicality of the device. By setting the mounting groove 403, external dust and debris can be filtered through 503 during use, and the mounting screw 501 makes it easier for workers to install and remove the dustproof net 5. By setting the fixing groove 402, the position of the baffle 4 can be restricted by the rotating rod 105 during use, so that it will not shift during use, thus improving the practicality of the device.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
