DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] In order to solve the technical problem in the prior art that the ends are easily damaged under the combined effects of the environment, the present invention provides a cable trench cover that can ensure the use function of the vulnerable parts of the cover and avoid end damage.

[0022] See also Figure 1 , Figure 1 The figure is a schematic diagram of the structure of a cable trench cover in one embodiment of the present invention.

[0023] The present invention provides a cable trench cover 100, comprising a concrete slab body 1 and a steel frame 2, wherein the concrete slab body 1 has an installation side 12 relatively arranged along a first direction, and a lap portion 11 is convexly formed on the upper part of the installation side 12; the steel frame 2 is arranged in the concrete slab body 1, and the steel frame 2 comprises a first stress-bearing reinforcement group, a second stress-bearing reinforcement group and a shear reinforcement 23, the first stress-bearing reinforcement group and the second stress-bearing reinforcement group are arranged along a direction toward the bottom of the concrete slab and are both arranged in an arch shape, the end of the first stress-bearing reinforcement group extends to the lap portion 11, and the end of the second stress-bearing reinforcement group extends to the edge where the installation side 12 intersects with the lower side of the concrete slab body 1, and the shear reinforcement 23 connects the first stress-bearing reinforcement group and the second stress-bearing reinforcement group.

[0024] In this embodiment, the lap joint 11 and the end portions of the first stress-bearing reinforcement group and the second stress-bearing reinforcement group together form an inverted L-shaped structure, which is placed on the cable trench structure to form lateral and longitudinal displacement constraints, which is beneficial to the fixation of the cable trench cover 100. At the same time, since the first stress-bearing reinforcement group and the second stress-bearing reinforcement group are arranged in the direction toward the bottom of the concrete slab 1 and are both arched, when the upper force is transmitted to the end of the concrete slab body 1, supporting forces are generated in the lateral and longitudinal directions respectively, forming a composite force. In addition, the interface between the lap joint 11 and the cable trench structure forms a large shear resistance, which is beneficial to withstand shear force, ensure the use function of the fragile parts of the cover 4, and avoid end damage.

[0025] In one embodiment, see Figures 1 to 3 , the arching amplitude of the first stress-bearing reinforcement group is smaller than that of the second stress-bearing reinforcement group.

[0026] In this embodiment, the middle parts of the first stress-bearing reinforcement group and the second stress-bearing reinforcement group are both arched upward, and the middle parts are close to each other, that is, the arching amplitude of the second stress-bearing reinforcement group is greater than the arching amplitude of the first stress-bearing reinforcement group. Such a setting is more in line with the stress characteristics of the plate body, and the vertical downward load is dispersed to both ends through the second stress-bearing reinforcement group, effectively increasing the bearing capacity of the structure.

[0027] In one embodiment, see Figure 2The first stress-bearing reinforcement group includes a plurality of first stress-bearing reinforcements 21 spaced apart along the second direction, the second stress-bearing reinforcement group includes a plurality of second stress-bearing reinforcements 22 spaced apart along the second direction, the number of the first stress-bearing reinforcements 21 is greater than the number of the second stress-bearing reinforcements 22, a plurality of the second stress-bearing reinforcements 22 correspond to part of the first stress-bearing reinforcements 21, and both ends of the second stress-bearing reinforcements 22 are respectively connected to the corresponding first stress-bearing reinforcements 21 through the shear reinforcements 23, wherein the first direction and the second direction are perpendicular to each other.

[0028] In this embodiment, the middle part of each of the first stress-bearing reinforcements 21 is arched upward, and its two ends extend to the overlap portion 11, the middle part of each of the second stress-bearing reinforcements 22 is arched upward, and its two ends extend to the edge where the installation side 12 intersects with the lower side of the concrete slab 1, and in the concrete slab 1, the density of the second stress-bearing reinforcements 22 is less than the density of the first stress-bearing reinforcements 21. Such an arrangement is beneficial to reducing the dead weight, and two shear reinforcements 23 are provided, and the two shear reinforcements 23 are arranged at intervals along the first direction, and they respectively connect the areas near the ends of the first stress-bearing reinforcements 21 and the second stress-bearing reinforcements 22, and the first stress-bearing reinforcements 21 and the second stress-bearing reinforcements 22 are connected through the shear reinforcements 23 to form an integral structure.

[0029] In one embodiment, see Figure 1 and Figure 4 A mounting groove 13 is provided on the upper side of the concrete slab body 1; the cable trench cover 100 also includes a lifting ring 3 and a cover plate 4, the lifting ring 3 is provided at the bottom of the mounting groove 13, the cover plate 4 is movably provided at the notch of the mounting groove 13, and the cover plate 4 is used to open and close the mounting groove 13.

[0030] In this embodiment, the cable trench cover 100 has two usage modes. When the cable trench cover 100 is permanently buried under the sidewalk, the cable trench cover 100 does not need to be disassembled. At this time, the upper side of the cable trench cover 100 is a plane. When the cable trench cover 100 needs to expose the inspection port and can be opened as part of the sidewalk, it is necessary to set a handle ring 3 and other components to facilitate the lifting of the cable trench cover 100. Therefore, the present application can make specific settings for the cable trench cover 100 according to the usage. In the embodiment where the cable trench cover 100 needs to expose the inspection port and can be opened as part of the sidewalk, the upper side of the concrete slab 1 is close to the installation side. A mounting groove 13 is provided at the position 12, and the lifting ring 3 is arranged at the bottom of the mounting groove 13 and fixed. By setting the lifting ring 3, it is convenient to lift the cable trench cover 100 during maintenance, and the cover plate 4 is movably arranged at the notch of the mounting groove 13, and the cover plate 4 is adapted to the mounting groove 13. The cover plate 4 can open and close the mounting groove 13. When maintenance is required, the cover plate 4 opens the mounting groove 13 to expose the lifting ring 3 for easy lifting. When it is used as a part of the sidewalk at ordinary times, the cover plate 4 is covered at the notch of the mounting groove 13, thereby closing the mounting groove 13. On the one hand, it is more beautiful, and on the other hand, it is not easy to trip pedestrians and accumulate dirt.

[0031] In this embodiment, two installation grooves 13 are provided, and the two installation grooves 13 are spaced apart along the first direction. Correspondingly, two cover plates 4 and two lifting rings 3 are provided. By providing two lifting rings 3, the stability of the cable trench cover plate 100 during lifting is ensured.

[0032] In one embodiment, the lifting ring 3 is connected to the shear reinforcement 23 .

[0033] In this embodiment, the lower end of the lifting ring 3 extends downward into the concrete slab body and is connected and fixed to the first load-bearing reinforcement 21, the second load-bearing reinforcement 22 and the shear reinforcement 23. With this arrangement, when it is lifted for maintenance, the steel skeleton 2 will be lifted as a whole, which is beneficial to the structural integrity.

[0034] In one embodiment, see Figure 4 The cover plate 4 is movable in the vertical direction and is rotatably installed in the groove of the installation groove 13 along the vertical axis, so as to have an open state in which it can move upward and rotate to be offset from the installation groove 13, and a closed state in which it can rotate to correspond to the installation groove 13 and move downward to cover the installation groove 13; the cable trench cover plate 100 also includes a driving mechanism 5, which is arranged in the installation groove 13 and connected to the cover plate 4 to drive the cover plate 4 to move.

[0035] The specific activity mode of the cover plate 4 is not limited, and it can be a flip type, a sliding type, or a detachable snap-on type. In this embodiment, the cover plate 4 can move in the vertical direction and rotate with one end as the axis. In the closed state, the cover plate 4 extends into the installation groove 13, and its upper side is flush with the upper side of the concrete slab body 1 to ensure the overall beauty and avoid protrusions that trip pedestrians. When lifting is required, the driving mechanism 5 first drives the cover plate 4 to move upward, so that the cover plate 4 extends out of the installation groove 13 At this time, the cover plate 4 is located directly above the installation groove 13, and there is still a situation where the lifting ring 3 is blocked. Therefore, the driving mechanism 5 drives the cover plate 4 to rotate about one end axis. At this time, the cover plate 4 is staggered with the installation groove 13 and is in an open state. At this time, the lifting ring 3 is completely exposed, which is conducive to lifting. When the maintenance is completed, the driving mechanism 5 drives the cover plate 4 to rotate so that the cover plate 4 is located directly above the installation groove 13, and then drives it to move downward and extend into the installation groove 13 to return to the initial state.

[0036] In one embodiment, see Figure 4 The driving mechanism 5 includes a mounting column 51, a screw rod 52 and a motor 53. The mounting column 51 is arranged on the lower side of the cover plate 4. The mounting column 51 is provided with a threaded hole. The screw rod 52 is rotatably installed in the mounting groove 13 along the vertical direction. The screw rod 52 is threadedly connected to the mounting column 51, and the motor 53 is connected to the lower end of the screw rod 52.

[0037] In this embodiment, the mounting post 51 is located at the lower side of the cover plate 4 near its end position, and a threaded hole extending in the vertical direction is provided in the middle of the mounting post 51, and the screw rod 52 is extended in the vertical direction. The screw rod 52 is rotatably installed in the mounting slot 13 in the vertical direction, and the screw rod 52 is threadedly connected to the threaded hole. The motor 53 is arranged in the mounting slot 13 and connected to the lower end of the screw rod 52, and is used to drive the screw rod 52 to rotate. When in use, the cover plate 4 extends into the mounting slot 13 in the initial state. Due to the limit of the mounting slot 13, the motor 53 rotates forward, driving the screw rod 52 to rotate, and the screw rod 52 is threadedly matched with the threaded hole, thereby driving the cover plate 4 and the mounting post 51 to move upward until the cover plate 4 completely extends out of the mounting slot 13, at which time the cover plate 4 is out of the limit of the mounting slot 13. When the screw rod 52 rotates, no relative movement is found between the screw rod 52 and the mounting post 51. At this time, the screw rod 52 drives the cover plate 4 and the mounting post 51 to rotate synchronously, thereby rotating the cover plate 4 to the side. When it is necessary to cover, it can be placed on the side of the mounting groove 13 through an external limit block or the operator's hand to act as a limit. Then the motor 53 is started. The motor 53 drives the screw rod 52, the mounting post 51 and the cover plate 4 to rotate in the opposite direction until the cover plate 4 abuts against the external limit block or the operator's hand. At this time, the cover plate 4 is directly above the mounting groove 13. Since the cover plate 4 is limited, the screw rod 52 is threadedly matched with the threaded hole, thereby driving the cover plate 4 to move downward until the cover plate 4 extends into the mounting groove 13 and returns to the initial state, completing the covering state of the cover plate 4.

[0038] In another embodiment, the driving mechanism 5 includes a connecting column, a lifting assembly and a rotating assembly. The connecting column is arranged on the lower side of the cover plate 4, and the lifting assembly is arranged in the mounting groove 13. The lifting part of the lifting assembly is connected to the connecting column, and the lifting part and the connecting column can rotate relative to each other. The lifting assembly is used to drive the connecting column to move in the vertical direction. The rotating assembly is arranged in the mounting groove 13, and the rotating assembly is connected to the connecting column to drive the connecting column to rotate. When the lifting assembly drives the cover plate 4 to extend out of the mounting groove 13, the rotating assembly drives the cover plate 4 to rotate.

[0039] Specifically, the lifting assembly includes an electric cylinder, a push rod of the electric cylinder constitutes the lifting part, and the rotating assembly includes a mounting plate, a gear, a gear ring and a driving motor. The mounting plate is installed at the upper end of the lifting part, and the lower end of the connecting column is rotatably installed on the mounting plate along the axis in the vertical direction. The gear ring is arranged on the outer periphery of the connecting column, and the gear is rotatably installed on the mounting plate along the axis in the vertical direction and meshes with the gear ring. The driving motor is installed on the mounting plate and connected to the gear to drive the gear to rotate. During specific use, when the electric cylinder pushes the cover plate 4 out of the mounting groove 13, the electric cylinder stops working and the driving motor starts. The driving motor drives the gear to rotate, and the gear meshes with the gear ring, thereby driving the connecting column and the cover plate 4 to rotate, thereby opening the mounting groove 13.

[0040] In one embodiment, see Figure 4 The cable trench cover 100 also includes a power module 6 and a power generation module. The power module 6 is arranged in the installation groove 13 and is electrically connected to the driving mechanism 5. The power generation module is arranged on the cover 4 and is electrically connected to the power module 6.

[0041] In this embodiment, the power module 6 is arranged inside the installation groove 13, and the power module 6 can provide electrical energy to the driving mechanism 5 to ensure the normal operation of the driving mechanism 5. The power generation module is arranged on the cover plate 4, and the power generation module can generate electricity to charge the power module 6 to prevent the power module 6 from running out of power.

[0042] In one embodiment, see Figure 4 The power generation module includes a pressure power generation plate 7, and the pressure power generation plate 7 is embedded on the upper side of the cover plate 4.

[0043] In this embodiment, the pressure power generation plate 7 is located on the upper side of the cover plate 4 . When pedestrians walk through the cable trench cover plate 100 , they step on the pressure power generation plate 7 to generate electricity and store it in the power module 6 .

[0044] It should be noted that the pressure power generation plate 7 is a prior art and will not be described in detail here.

[0045] In another embodiment, the power generation module may also be a solar panel.

[0046] In one embodiment, see Figure 4The cable trench cover 100 also includes a communication module and a control module 8. The control module 8 and the communication module are both arranged in the installation groove 13. The communication module is electrically connected to the control module 8 for communicating data with external equipment and transmitting it to the control module 8. The control module 8 is electrically connected to the driving mechanism 5 to control the operation of the driving mechanism 5 according to the signal transmitted by the communication module.

[0047] In this embodiment, in order to control the operation of the driving mechanism 5 , a communication module and a control module 8 are further provided in the installation slot 13 . The communication module is used to communicate with the outside world for human-computer interaction, and the control module 8 is used to control the operation of the driving mechanism 5 .

[0048] Specifically, the communication module includes any one or more combinations of the following: an infrared communication device, a radio wave communication device, a microwave communication device, a Bluetooth communication device, and a Wi-Fi communication device, all of which are prior arts and will not be elaborated herein.

[0049] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail: In specific use, when it is necessary to lift the cable trench cover 100, the motor 53 rotates forward, driving the screw rod 52 to rotate, and the screw rod 52 is threadedly matched with the threaded hole, thereby driving the cover plate 4 and the mounting column 51 to move upward until the cover plate 4 is completely extended out of the mounting groove 13. At this time, the cover plate 4 is disengaged from the limit of the mounting groove 13. When the screw rod 52 rotates, no relative movement is found between the screw rod 52 and the mounting column 51. At this time, the screw rod 52 drives the cover plate 4 and the mounting column 51 to rotate synchronously, thereby rotating the cover plate 4 to the side. When it is necessary to cover, An external limit block or the operator's hand can be placed beside the installation groove 13 to act as a limit, and then the motor 53 is started. The motor 53 drives the screw rod 52, the installation column 51 and the cover plate 4 to rotate in the opposite direction until the cover plate 4 abuts against the external limit block or the operator's hand. At this time, the cover plate 4 is directly above the installation groove 13. Since the cover plate 4 is limited, the screw rod 52 is threadedly matched with the threaded hole, thereby driving the cover plate 4 to move downward until the cover plate 4 extends into the installation groove 13 and returns to the initial state, completing the covering state of the cover plate 4.

[0050] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
