DETAILED DESCRIPTION
[0020] At present, the grounding methods of cable trenches are as follows Figure 1 As shown. A first grounding wire is arranged on both inner side surfaces of the trench body structure of the cable trench, and a first bracket and a second bracket arranged on the two inner side surfaces are respectively connected to the two first grounding wires, and the two first grounding wires are respectively welded to the grounding electrode located below the trench body structure through the second grounding wire and the third grounding wire. Since the second grounding wire and the third grounding wire need to pass through the trench body structure and be welded to the grounding electrode, a channel for the second grounding wire and the third grounding wire to pass through needs to be reserved on the trench body structure, and after the second grounding wire and the third grounding wire are welded to the grounding electrode, the channel reserved by the trench body structure needs to be sealed with concrete, and cast-in-place concrete needs to be used for maintenance. Therefore, the current grounding method of the cable trench has a relatively cumbersome construction process and a long construction period.
[0021] In view of the above reasons, an embodiment of the present application provides a cable trench, which does not require reserved channels for the second grounding wire and the third grounding wire, and thus does not require concrete pouring and maintenance. The construction is convenient and quick, which improves construction efficiency and shortens construction time.

[0024] like Figure 2 and Figure 3 As shown, a cable trench provided in an embodiment of the present application includes a trench structure 100, a trench cover 200, a conductive component 300, two first grounding wires 400, a first bracket 500, a second bracket 600, a plurality of second grounding wires 700, a plurality of third grounding wires 800 and a grounding electrode 900.
[0025] The trench cover 200 covers the opening of the trench structure 100 .
[0026] The conductive component 300 is pre-buried in the side wall of the trench structure 100, with one end thereof extending into the interior of the trench structure 100 and the other end thereof extending out of the trench structure 100. Specifically, when the trench structure 100 is prefabricated, after the reinforcement of the trench structure 100 is completed, the conductive component 300 is arranged between the reinforcements, and the two ends of the guide component extend out of the reinforcements; after the concrete is poured, the two ends of the conductive component 300 are located inside and outside the trench structure 100, respectively.
[0027] The two first grounding wires 400 are respectively disposed on two inner side surfaces of the trench structure 100, and both extend along the length direction of the trench structure 100. Exemplarily, the first grounding wires 400 are galvanized flat steel.
[0028] The first bracket 500 is disposed on an inner side of the trench structure 100 and is electrically connected to the corresponding first grounding wire 400. When the cable carried by the first bracket 500 leaks electricity, or the first bracket 500 is statically charged or struck by lightning, the current on the first bracket 500 is transmitted to the first grounding wire 400 connected to the first bracket 500. Specifically, the first bracket 500 is welded to the first grounding wire 400; of course, in other embodiments of the present application, the first bracket 500 is connected to the first grounding wire 400 by bolting.
[0029] The second bracket 600 is disposed on the other inner side of the trench structure 100 and is electrically connected to the corresponding first grounding wire 400. When the cable carried by the second bracket 600 leaks electricity, or the second bracket 600 is statically charged or struck by lightning, the current on the second bracket 600 is transmitted to the first grounding wire 400 connected to the second bracket 600. Specifically, the second bracket 600 is welded to the first grounding wire 400; of course, in other embodiments of the present application, the second bracket 600 is connected to the first grounding wire 400 by bolt connection.
[0030] For example, Figure 2 and Figure 3 As shown, a power cable is installed on the first bracket 500 , and a communication cable is installed on the second bracket 600 .
[0031] A plurality of second grounding wires 700 are arranged at intervals on an inner side surface of the groove body structure 100 along the length direction of the groove body structure 100, and one end of each second grounding wire 700 is electrically connected to the corresponding first grounding wire, and the other end of each second grounding wire 700 is electrically connected to the end of the conductive component 300 located in the groove body structure 100.
[0032] A plurality of third grounding wires 800 are spaced apart on the other inner side surface of the groove body structure 100 along the length direction of the groove body structure 100 , and one end of each third grounding wire 800 is connected to the corresponding first grounding wire, and the other end of each third grounding wire 800 is electrically connected to the end of the conductive component 300 located inside the groove body structure 100 .
[0033] Specifically, one end of the plurality of second grounding wires 700 and one end of the plurality of third grounding wires 800 are respectively welded to the two first grounding wires 400, and the other end of the plurality of second grounding wires 700 and the other end of the plurality of third grounding wires 800 are welded to the end of the conductive component 300 located in the groove structure 100. In other embodiments of the present application, one end of the plurality of second grounding wires 700 and one end of the plurality of third grounding wires 800 can also be respectively connected to the two first grounding wires 400 by bolts; the end of the conductive component 300 located in the groove structure 100 is provided with threads, and the other end of the plurality of second grounding wires 700 and the other end of the plurality of third grounding wires 800 are both provided with through holes, and the end of the conductive component 300 located in the groove structure 100 passes through the through holes on the second grounding wires 700 and the through holes on the third grounding wires 800, and is tightened and fixed with nuts.
[0034] Exemplarily, the second grounding wire 700 and the third grounding wire 800 are galvanized flat steel.
[0035] The grounding electrode 900 is located outside the trench structure 100, one end of the grounding electrode 900 is inserted into the ground, and the other end of the grounding electrode 900 is electrically connected to the end of the conductive component 300 located outside the trench structure 100. Specifically, the grounding electrode 900 is connected to the end of the conductive component 300 located outside the trench structure 100 through a wire, such as a galvanized flat steel.
[0036] The current generated on the first bracket 500 and the second bracket 600 is transmitted to the first grounding wire 400, and the current on the two first grounding wires 400 is respectively transmitted to multiple second grounding wires 700 and multiple third grounding wires 800, and then transmitted to the underground through the conductive component 300 and the grounding electrode 900. The cable trench structure does not need to reserve a channel for the second grounding wire 700 and the third grounding wire 800, and thus does not need to be poured and maintained with concrete. It only needs to connect the second grounding wire 700 and the third grounding wire 800 to one end of the conductive component 300, and connect the grounding electrode 900 to the other end of the conductive component 300. The construction is convenient and fast, which improves the construction efficiency and shortens the construction time.
[0037] In some embodiments of the present application, reference Figure 4 The conductive assembly 300 includes an insulating fixture 310 and a conductive rod 320. The insulating fixture 310 is detachably connected to the reinforcement of the trench structure 100. The conductive rod 320 is mounted on the insulating fixture 310, and the two ends of the conductive rod 320 are respectively located inside and outside the trench structure 100. The end of the conductive rod 320 located inside the trench structure 100 is connected to the second grounding wire 700 and the third grounding wire 800, and the end of the conductive rod 320 located outside the trench structure 100 is connected to the grounding electrode 900.
[0038] The insulating fixture 310 is detachably connected to the reinforcement of the trench structure 100, so that the insulating fixture 310 can be quickly connected to the reinforcement. The conductive rod 320 is connected to the reinforcement of the trench structure 100 through the insulating fixture 310, so that the conductive rod 320 remains fixed in position when the trench structure 100 is prefabricated.
[0039] Exemplarily, the conductive rod 320 is a screw; the end of the conductive rod 320 located inside the trench structure 100 passes through the second grounding wire 700 and the third grounding wire 800, and is tightened with a nut; the grounding electrode 900 is connected to the conductive rod 320 through a wire, and the end of the conductive rod 320 located outside the trench structure 100 passes through the wire and is tightened with a nut. The conductive rod 320 in the form of a screw can quickly connect the second grounding wire 700, the third grounding wire 800 and the grounding electrode 900, thereby improving construction efficiency. Of course, the conductive rod 320 can also be other specific structures, for example, the conductive rod 320 can also be an optical axis.
[0040] Further, refer to Figure 5 The insulating fixing member 310 includes a clamping portion 311 and a sleeve portion 312 that are fixedly connected. The clamping portion 311 is provided with an opening and is configured to clamp the reinforcement of the trench structure 100. The sleeve portion 312 is connected to the conductive rod 320 by interference fit.
[0041] When the insulating fixing member 310 needs to be connected to the reinforcement of the trench structure 100, the reinforcement enters the clamping part 311 through the opening of the clamping part 311, so that the clamping part 311 clamps the reinforcement. The conductive rod 320 passes through the sleeve part 312, and the sleeve part 312 and the conductive rod 320 have an interference fit, so that the conductive rod 320 and the sleeve part 312 are connected and tightened to avoid looseness.
[0042] Exemplarily, the clamping portion 311 is integrally connected with the sleeve portion 312. Of course, the clamping portion 311 and the sleeve portion 312 can also be bonded or the like.
[0043] Continue to refer to Figure 5 The insulating fixing member 310 further includes a plurality of protrusions 313 , which are disposed on the outer side of the sleeve portion 312 , so that the insulating fixing member 310 is tightly connected to the concrete of the trench structure 100 .
[0044] also, Figure 5 The outer side of the clamping portion 311 is also provided with a fixing groove 314, and the fixing groove 314 surrounds the through hole of the clamping portion 311 for accommodating the reinforcement. After the clamping portion 311 is connected to the reinforcement, the clamping portion 311 and the reinforcement can be tied with a cable tie, and the cable tie is located in the fixing groove, so that the clamping portion 311 and the reinforcement are more firmly connected.
[0045] Figure 2 The cable trench shown in the figure has a conductive component 300, the lower end of the second grounding wire 700 is connected to the conductive component 300, and the third grounding wire 800 is connected to the conductive component 300 after being bent at the bottom surface of the trench structure 100, so that the third grounding wire 800 is relatively long and has a high cost. In order to reduce the cost of the cable trench, in some embodiments of the present application, reference is made to Figure 3 , conductive components 300 are disposed on both side walls of the trench structure 100 ; the conductive components 300 disposed on both side walls of the trench structure 100 are respectively connected to the second grounding wire 700 and the third grounding wire 800 .
[0046] The lower ends of the second grounding wire 700 and the third grounding wire 800 are both connected to the corresponding conductive components 300, and the third grounding wire 800 is no longer required. Figure 2 The portion located at the bottom of the trench structure 100 saves costs and facilitates the installation of the third grounding wire 800 inside the trench structure 100.
[0047] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.
[0048] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
