Description
Technical Field
[0001] The present application relates to the technical field of cable trench drainage, and in particular to a cable trench water accumulation detection and drainage device. Background Art
[0002] A cable trench is a special trench or conduit system used to bury cables. It is usually used to transport cables from one location to another, either inside a building, underground, or outdoors on the ground.
[0003] In order to facilitate daily maintenance and management, some outdoor ground cable trenches adopt an open design, which is usually used for temporary or low-voltage cable wiring, such as in construction sites, parks, squares, etc. A water pipe is usually buried under this cable trench, and a through hole connected to the water pipe is opened at the bottom of the cable trench to achieve the drainage function of the cable trench. However, the through holes of the open cable trench are easily blocked by fallen leaves, dust and other debris, resulting in the inability to drain water, which easily leads to water accumulation in the cable trench. In addition, since a large number of cables are arranged in the cable trench, it is inconvenient and unsafe to clean the through holes when there is water accumulation. Utility Model Content
[0004] In order to improve the drainage function of the cable trench and reduce the occurrence of water accumulation in the cable trench, the present application provides a cable trench water accumulation detection and drainage device.

[0007] When the water level in the cable trench reaches the warning value, the control component controls the opening and closing component to drive the sealing plate to open the drain port;
[0008] When the water level in the cable trench drops to the safe water level specified in the design, the control component controls the opening and closing component to drive the sealing plate to close the drain outlet.
[0009] By adopting the above technical solution, under normal circumstances, the accumulated water is discharged into the drainage pipe through the drainage hole to achieve drainage of the cable trench;
[0010] When the cable trench cannot be drained smoothly due to heavy rainfall, clogged drainage holes and other reasons, water begins to accumulate in the cable trench. The control component can identify whether the water level in the cable trench has reached the warning value. When the water level reaches the warning value, the control component controls the opening and closing component to drive the sealing plate to open the drainage port for auxiliary drainage. The water flows into the opening and closing component and then into the drainage pipe, so that the accumulated water can be drained away in time, and the cable trench can achieve normal drainage function;
[0011] When the accumulated water drops to the safe water level specified in the design, the control component controls the opening and closing component to drive the sealing plate to close the drain outlet, so that the staff can enter the cable trench to clean the blocked drainage holes when the rain stops. The staff will not step on empty space at the drain outlet and get injured. The low water level avoids the risk of leakage caused by the cable being soaked by accumulated water, improves the drainage function of the cable trench, reduces the occurrence of water accumulation in the cable trench, and improves the safety performance of the cable trench.
[0012] Optionally, the opening and closing assembly includes a drainage box, which is buried in the foundation, the drainage box is connected to the drainage pipe, a motor is arranged in the drainage box, the motor is connected to a rotating shaft, a gear is arranged on the rotating shaft, the sealing plate is slidably connected to the drainage box, the sealing plate is provided with a rack, and the rack is meshed with the gear.
[0013] By adopting the above technical solution, the motor drives the gear to rotate, and the gear drives the rack to move, so that the rack drives the sealing plate to move towards or away from the drain outlet, thereby realizing the opening and closing of the drain outlet.
[0014] Optionally, a slide rail is provided in the drainage box, the sealing plate is connected to a support frame, the rack is provided on the support frame, the support frame is rotatably connected to a pulley, the slide rail supports the pulley, and the pulley rolls along the slide rail.
[0015] By adopting the above technical solution, the pulley rolls along the slide rail, and the support frame drives the sealing plate to move in a direction close to or away from the drain outlet, so that the movement of the sealing plate is more stable and smooth.
[0016] Optionally, a guide plate is provided in the drainage box, and a guide groove is formed on the guide plate, and the guide groove is an L-shaped groove. The support frame is hinged with a plurality of rotating rods, and the rotating rods are hinged to the sealing plate. One end of the rotating rod hinged to the sealing plate is also rotatably connected to a guide wheel, and the guide wheel is located in the guide groove. A movable groove is formed on the cable trench, and the movable groove is connected to the drain outlet. When the sealing plate moves toward the drain outlet, the sealing plate first translates horizontally and then rises obliquely horizontally until the drain outlet is closed.
[0017] By adopting the above technical scheme, when closing the drain outlet, the motor drives the gear to rotate, the gear drives the rack to move, and the rack drives the support frame and the sealing plate to move in the direction close to the drain outlet, and the roller first moves along the horizontal section of the guide groove and then moves along the vertical section of the guide groove along one side of the guide groove, so that the support frame, the rotating rod and the sealing plate are first moved horizontally, and then the support frame is moved horizontally. At the same time, the rotating rod rotates around the hinge point of the support frame, and the sealing plate moves vertically upward and closes the drain outlet. The design of the sealing plate moving horizontally and rising to close the drain outlet is compared with the design of closing the opening with a flip plate. When designing a large-sized drain outlet, the design height of the drain box is not affected by the size of the drain outlet, thereby reducing the excavation depth of the foundation, and in order to prevent water from flowing back into the drain box, the top surface elevation of the drain pipe is usually not higher than the bottom surface elevation of the drain box. Therefore, the pre-buried depth of the drain pipe can also be made unaffected by the size of the drain outlet, further reducing foundation excavation and facilitating construction.
[0018] Optionally, the drainage box is connected to a plurality of drainage pipes, the drainage pipes are in communication with the drainage pipes, and the bottom elevation of the drainage box is not lower than the top elevation of the drainage pipes.
[0019] By adopting the above technical solution, multiple drainage pipes can improve the drainage efficiency of the drainage box.
[0020] Optionally, the control component includes a shell, the shell is mounted on the inner bottom wall of the cable, the shell is provided with a water outlet, a support rod is provided in the shell, a first contact sensor is provided on the top of the support rod, the support rod supports a floating plate, a second contact sensor is provided on the inner top wall of the shell, and the top surface elevation of the support rod is higher than the top wall elevation of the water outlet;
[0021] When the floating plate contacts the first contact sensor, the motor is started to make the sealing plate close the drain port;
[0022] When the floating plate contacts the second contact sensor, the motor is started to enable the sealing plate to open the drain port.
[0023] By adopting the above technical scheme, the accumulated water flows into the outer shell from the water inlet. When the accumulated water covers the top of the support rod, the float plate begins to float up. When the water level reaches the warning value, the float plate contacts the second contact sensor. At this time, the motor starts to make the sealing plate open the drain port for auxiliary drainage. When the accumulated water level drops to a safe water level, the float plate contacts the first contact sensor. At this time, the motor starts again to make the float plate close the drain port. This not only improves the drainage function, but also can judge the water level of the accumulated water according to the opening and closing of the drain port, thereby achieving a detection effect.
[0024] Optionally, a water baffle is provided on the top of the cable trench, and the width of the water baffle is greater than the length of the cable bracket.
[0025] By adopting the above technical solution, the water retaining plate can block rainwater and reduce the corrosion of the cable trench caused by long-term rainwater pouring on the cable trench.
[0026] Optionally, a water guide groove is provided on a side of the bottom wall of the water baffle away from the side wall of the cable trench, and the water guide groove is arranged along the length direction of the water baffle.
[0027] By adopting the above technical solution, the water guide groove can reduce the situation where rainwater falls onto the cable along the bottom wall of the water retaining plate.
[0028] In summary, the present application includes at least one of the following beneficial technical effects:
[0029] 1. When the cable trench cannot be drained smoothly due to heavy rainfall, clogged drainage holes and other reasons, water begins to accumulate in the cable trench. The control component can identify whether the water level in the cable trench has reached the warning value. When the water level reaches the warning value, the control component controls the opening and closing component to drive the sealing plate to open the drainage port for auxiliary drainage. The water flows into the opening and closing component and then into the drainage pipe, so that the accumulated water can be drained away in time, and the cable trench can achieve normal drainage function;
[0030] 2. When the accumulated water drops to the safe water level specified in the design, the control component controls the opening and closing component to drive the sealing plate to close the drainage port, so that the staff can enter the cable trench to clean the blocked drainage holes when the rain stops. The staff will not step on the drainage port and get injured. The low water level avoids the risk of leakage caused by the cable being soaked by the accumulated water, improves the drainage function of the cable trench, reduces the accumulation of water in the cable trench, and improves the safety performance of the cable trench;
[0031] 3. Compared with the design of closing the opening with a flip plate, the design of closing the drain outlet by sliding the cover plate upward is beneficial in designing a large-sized drain outlet. The design height of the drain box is not affected by the size of the drain outlet, thereby reducing the excavation depth of the foundation. In addition, in order to prevent water from flowing back into the drain box, the top elevation of the drain pipe is usually not higher than the bottom elevation of the drain box. Therefore, the pre-buried depth of the drain pipe is not affected by the size of the drain outlet, further reducing foundation excavation and facilitating construction.

DETAILED DESCRIPTION
[0040] The following is combined with Figure 1-6 This application is described in further detail.
[0041] The embodiment of the present application discloses a cable trench water accumulation detection and drainage device.
[0042] like Figure 1 and Figure 2 The cable trench water accumulation detection and drainage device comprises a cable trench 1, a plurality of cable brackets 11 are bolted to both sides of the cable trench 1 along its own length direction, a drainage pipe 2 is arranged below the cable trench 1, the drainage pipe 2 is pre-buried in the foundation, a plurality of drainage holes 12 are opened along the length direction of the bottom wall of the cable trench 1, the drainage holes 12 are connected with the drainage pipe 2, a drainage port 13 is opened on the bottom wall of the cable trench 1, an opening and closing component 3 is installed at the bottom of the cable trench 1, the opening and closing component 3 is pre-buried in the foundation, the opening and closing component 3 is connected with a sealing plate 4, and the opening and closing component 3 is connected with the drainage pipe 2, and a control component 5 is installed on the inner bottom wall of the cable trench 1. Water retaining plates 6 are bolted to both sides of the top of the cable trench 1, the water retaining plates 6 are arranged along the length direction of the cable trench 1, and a water guide groove 61 is opened on the bottom wall of the water retaining plate 6 along the length direction, and the water guide groove 61 is arranged on the side of the water retaining plate 6 away from the cable trench 1.
[0043] Normally, the accumulated water is discharged into the drainage pipe 2 through the drainage hole 12, thereby draining the cable trench 1;
[0044] When the cable trench 1 cannot be drained smoothly due to heavy rainfall, blockage of the drainage hole 12 and other reasons, water begins to accumulate in the cable trench 1. The control component 5 can identify whether the water level in the cable trench 1 has reached the warning value. When the water level reaches the warning value, the control component 5 controls the opening and closing component 3 to drive the sealing plate 4 to open the drainage port 13 for auxiliary drainage. The water flows into the opening and closing component 3 and then into the drainage pipe 2, so that the accumulated water can be drained away in time, and the cable trench 1 can achieve normal drainage function.
[0045] When the accumulated water drops to the safe water level specified in the design, the control component 5 controls the opening and closing component 3 to drive the sealing plate 4 to close the drain outlet 13, so that the staff can enter the cable trench 1 to clean the blocked drain hole 12 when the rain stops. The staff will not step on the air at the drain outlet 13 and get injured, which avoids the risk of leakage caused by the cable being soaked by accumulated water, improves the drainage function of the cable trench 1, reduces the occurrence of water accumulation in the cable trench 1, and improves the safety performance of the cable trench 1.
[0046] like Figure 2 , Figure 3 and Figure 4 The opening and closing assembly 3 includes a drainage box 31, which is buried in the foundation. The bottom elevation of the drainage box 31 is higher than the top elevation of the drainage pipe 2. The bottom of the drainage box 31 is connected to a plurality of drainage pipes 32, which are connected to the drainage pipe 2. Slide rails 33 are installed on both sides of the drainage box 31. A support frame 34 is provided in the drainage box 31. Two pulleys 35 are rotatably connected on both sides of the support frame 34. One side of the pulley 35 is inserted into the slide rail 33 so that the pulley 35 can roll along the slide rail 33. A rack 36 is installed at the bottom of the support frame 34. The rack 36 is located in the middle of the support frame 34. A rotating shaft 37 is rotatably connected in the drainage box 31. A gear 38 is coaxially fixed to the rotating shaft 37. The gear 38 meshes with the rack 36. A motor 39 is installed on one side of the drainage box 31. The motor 39 is connected to the rotating shaft 37. Both ends of the support frame 34 are hinged with rotating rods 310 , and the two rotating rods 310 at the same end are respectively located on both sides of the support frame 34 , and one end of the four rotating rods 310 away from the support frame 34 is hinged to the sealing plate 4 .
[0047] like Figure 4 and Figure 5Guide plates 311 are fixed on both sides of the drainage box 31. The guide plates 311 are provided with guide grooves 312. The guide grooves 312 are L-shaped grooves, and the vertical ends of the guide grooves 312 are close to the drain outlet 13. When the sealing plate 4 fully opens the drain outlet 13, the two rotating rods 310 at one end of the support frame 34 away from the drain outlet 13 are rotatably connected with guide wheels 313. The guide wheels 313 are located at the hinge between the rotating rod 310 and the sealing plate 4, and the guide wheels 313 are coaxial with the hinge axis of the rotating rod 310 and the sealing plate 4. The guide wheels 313 are located in the guide grooves 312. The rotating rod 310 is always in a state of being tilted toward the drain outlet 13. A movable groove 314 is provided at the bottom of the cable trench 1. The movable groove 314 is opened along the circumference of the drain outlet 13 and is connected to the drain outlet 13.
[0048] like Figure 6 The control component 5 includes a shell 51, which is bolted to the inner bottom wall of the cable trench 1. The shell 51 is provided with a water outlet 511, which is opened to communicate with the inner bottom wall of the cable trench 1. Two support rods 52 are bolted to the inner wall of the cable trench 1. The support rods 52 are located in the shell 51, and the top surface elevation of the support rods 52 is higher than the top wall elevation of the water outlet 511. A first contact sensor 53 is embedded on the top of one of the support rods 52, and the first contact sensor 53 is flush with the top surface of the support rod 52. The two support rods 52 jointly support a floating plate 54. A second contact sensor 55 is installed on the inner top wall of the shell 51. The top surface elevation of the shell 51 is lower than the bottom surface elevation of the cable bracket 11.
[0049] When the cable trench 1 cannot be drained smoothly due to heavy rainfall or blockage of the drainage hole 12, water begins to accumulate in the cable trench 1, and the accumulated water flows into the housing 51 from the water inlet 511. When the accumulated water covers the top of the support rod 52, the floating plate 54 begins to float up. When the accumulated water level reaches the warning value, the floating plate 54 contacts the second contact sensor 55, and the motor 39 starts.
[0050] The motor 39 drives the gear 38 to rotate, the gear 38 drives the rack 36 to move, and the rack 36 drives the support frame 34 to move away from the drain outlet 13. Under the gravity of the sealing plate 4, the guide wheel 313 rolls along the vertical end of the guide groove 312, and the sealing plate 4 gradually descends vertically. When the guide wheel 313 enters the horizontal section of the guide groove 312, the support frame 34 drives the sealing plate 4 away from the drain outlet 13, so that the drain outlet 13 is opened, and auxiliary drainage is performed through the drain outlet 13. The accumulated water enters the drainage box 31 and then flows into the drainage pipe 2 through the drainage pipe 32;
[0051] When the water level drops to a safe level, the floating plate 54 contacts the first contact sensor 53, and the motor 39 starts again.
[0052] The motor 39 drives the gear 38 to rotate, the gear 38 drives the rack 36 to move, the rack 36 drives the support frame 34 and the sealing plate 4 to move towards the direction close to the drain outlet 13, the guide wheel 313 first moves along the horizontal section of the guide groove 312 and then moves along the vertical section of the guide groove 312 along one side of the guide groove 312, so that the support frame 34, the rotating rod 310 and the sealing plate 4 are first moved horizontally, and then the support frame 34 is moved horizontally. At the same time, the rotating rod 310 rotates around the hinge point of the support frame 34, and the sealing plate 4 moves vertically upward and closes the drain outlet 13, which not only improves the drainage function, but also can judge the water level of the accumulated water according to the opening and closing of the drain outlet 13, thereby achieving a detection function.
[0053] Compared with the design of closing the opening with a flip plate, the design of the sealing plate 4 sliding up and down to close the drain outlet 13 is advantageous in that when designing a large-sized drain outlet 13 for rapid drainage, the design height of the drain box 31 is not affected by the size of the drain outlet 13, thereby reducing the excavation depth of the foundation. In order to prevent water from flowing back into the drain box 31, the elevation of the top surface of the drain pipe 2 is usually not higher than the elevation of the bottom surface of the drain box 31. Therefore, the pre-buried depth of the drain pipe 2 is not affected by the size of the drain outlet 13, further reducing foundation excavation and facilitating construction.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
