Abstract
Description
Technical Field
[0001] This invention belongs to the field of drainage technology, specifically relating to a drainage device for cable trenches. Background Technology
[0002] Water can easily accumulate in power plant cable trenches due to rainwater seepage and groundwater infiltration. If it is not drained in time, it will accelerate the aging of cable insulation and even cause short circuit accidents, seriously threatening the safe operation of generator units.
[0003] Currently, monitoring and drainage of water accumulation in cable trenches mainly relies on manual inspections. Inspectors must periodically open the covers along the cable trenches one by one, visually assess the water level, and then transport mobile water pumps to the affected areas for drainage. This method is not only labor-intensive and time-consuming, but also has a fixed inspection cycle, making real-time monitoring difficult. Often, the problem is only discovered after the water has already caused damage. In the event of sudden weather events such as heavy rain, the manual response time is even more insufficient, making it impossible to promptly remove the water. Summary of the Invention

The inlet of the water pump is connected to one end of the pumping pipe, and the outlet of the water pump is connected to the outside. When the liquid level probe detects that the water level has reached a preset height, the baffle moves downward, and the baffle and the frame assemblies isolate the cable trench. Simultaneously, the water pump starts, draining the water from the cable trench.
[0006] The cable trench drainage device of this invention, through the setting of a liquid level probe, realizes automatic real-time monitoring of the water level in the cable trench, eliminating the need for manual opening of each cover to visually inspect the water level; through the cooperation of the baffle and frame components, it can automatically move downward to form an area isolation when the water level reaches a preset height, preventing further spread of water; through the water pump and drainage pipe, it realizes automatic drainage of water, eliminating the need for manual handling of mobile water pumps to the waterlogged area; through the coordinated operation of liquid level monitoring, baffle action and water pump start and stop, no manual judgment or operation is required, greatly reducing the labor intensity of manual inspection and solving the problem of delayed manual response.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figures 1-5 As shown, the cable trench drainage device of this embodiment includes a baffle 1, multiple frame assemblies 2, and a pumping assembly 3. The baffle 1 is slidably arranged in the vertical direction and is used to block accumulated water. The multiple frame assemblies 2 are respectively arranged on both sides of the baffle 1 in the horizontal direction. The baffle 1 and the frame assemblies 2 are slidably connected. The frame assemblies 2 include multiple liquid level probes 21, which are spaced apart in the vertical direction and are used to detect the water level. The pumping assembly 3 is arranged on the baffle 1 and includes a water pump 31 and a water pumping pipe 32. The inlet end of the water pump 31 is connected to one end of the water pumping pipe 32, and the outlet end of the water pump 31 is connected to the outside. When the liquid level probe 21 detects that the water level has reached a preset height, the baffle 1 moves downward, and the baffle 1 and the frame assemblies 2 isolate the cable trench. At the same time, the water pump 31 starts to drain the water in the cable trench.
[0025] The cable trench drainage device of this invention, through the setting of a liquid level probe, realizes automatic real-time monitoring of the water level in the cable trench, eliminating the need for manual opening of each cover to visually inspect the water level; through the cooperation of the baffle and frame components, it can automatically move downward to form an area isolation when the water level reaches a preset height, preventing further spread of water; through the water pump and drainage pipe, it realizes automatic drainage of water, eliminating the need for manual handling of mobile water pumps to the waterlogged area; through the coordinated operation of liquid level monitoring, baffle action and water pump start and stop, no manual judgment or operation is required, greatly reducing the labor intensity of manual inspection and solving the problem of delayed manual response. Especially in sudden weather such as heavy rain, it can respond promptly and automatically drain water.
[0026] Specifically, after water accumulates in the cable trench, the level probe 21 monitors the water level in real time. When the water level rises to a preset height, the control baffle 1 moves downward, so that the baffle 1 and the side frame components 2 work together to isolate the cable trench into an independent area, preventing the water from spreading further to other areas. At the same time, the control water pump 31 starts, and the water pump 31 pumps out the accumulated water through the water pipe 32 and discharges it to the outside until the water level drops to a safe height.
[0027] In some embodiments, a plurality of liquid level probes 21 are disposed on the side of the frame assembly 2 near the pumping pipe 32.
[0028] The cable trench drainage device of this invention avoids measurement deviation caused by the separation of the detection position and the pumping position by setting the liquid level probe on the side of the frame assembly close to the pumping pipe. This prevents situations where the water accumulation in the area where the pumping pipe is located exceeds the threshold but is not detected, or where the water accumulation in other areas does not reach the threshold but is mistakenly triggered for pumping.
[0029] Specifically, when the water level rises to the height of a certain level probe 21, the level probe 21 is triggered.
[0030] Furthermore, the liquid level probe 21 is existing technology and will not be described in detail.
[0031] In some embodiments, the frame assembly 2 further includes a mounting shell 22, a first motor 23, a lead screw 24, a threaded block 25, a moving rod 26, and a connecting plate 27. The mounting shell 22 has a guide groove 210, and the baffle 1 is slidably connected in the guide groove 210. The first motor 23 is fixedly mounted on the top of the mounting shell 22. The lead screw 24 is rotatably connected in the mounting shell 22 and is connected to the output end of the first motor 23. The threaded block 25 is threadedly sleeved on the lead screw 24. The moving rod 26 is fixedly connected to the threaded block 25 and is slidably connected to the mounting shell 22. The connecting plate 27 is fixedly connected to the top of the moving rod 26 and is fixedly connected to the top of the baffle 1.
[0032] The cable trench drainage device of this invention achieves the lifting and lowering of the baffle through the cooperation of a first motor, a lead screw, and a threaded block, eliminating the need for manual operation of the baffle. The sliding connection between the moving rod and the mounting shell ensures the smooth movement of the baffle during lifting and lowering. The driving force of the moving rod is transmitted to the top of the baffle through the connecting plate, making the baffle evenly stressed and ensuring that the baffle lifts and lowers vertically along the guide groove. This avoids poor sealing caused by the baffle tilting and effectively prevents water from leaking from the gap between the baffle and the frame assembly to adjacent areas.
[0033] Specifically, when the liquid level probe 21 detects that the water level has reached a preset height, the first motor 23 drives the lead screw 24 to rotate, and the lead screw 24 drives the threaded block 25 to move downward along the lead screw 24. The threaded block 25 drives the moving rod 26 to slide downward along the mounting shell 22, and the moving rod 26 drives the connecting plate 27 to move downward. The connecting plate 27 drives the baffle 1 to slide downward along the guide groove 210, so that the bottom of the baffle 1 contacts the bottom wall of the cable trench, thus dividing the cable trench into an independent area.
[0034] In some embodiments, sliding grooves 28 are provided on both sides of the inner wall of the mounting housing 22, and a through hole 29 extending to the outside is provided at the top of the inner wall of the sliding groove 28. The outer wall of the moving rod 26 is slidably connected to the inner wall of the sliding groove 28 and the through hole 29.
[0035] The cable trench drainage device of this invention provides guidance for the moving rod by setting a sliding groove, which restricts the horizontal displacement of the moving rod; and allows the moving rod to pass through the top of the mounting shell and connect with the connecting plate by setting a through hole.
[0036] Specifically, the moving rod 26 slides up and down along the sliding grooves 28 on both sides of the inner wall of the mounting housing 22. When the moving rod 26 moves upward, its top extends out of the mounting housing 22 through the through hole 29 at the top of the inner wall of the sliding groove 28, causing the connecting plate 27 to move upward. When the moving rod 26 moves downward, its top retracts from the through hole 29 into the sliding groove 28, causing the connecting plate 27 to move downward, thereby driving the baffle 1 to rise and fall.
[0037] In some embodiments, a rubber sleeve is fitted onto the movable rod 26.
[0038] The cable trench drainage device of this invention fills the gap between the moving rod and the sliding groove and the inner wall of the through hole by setting the rubber sleeve, preventing water or impurities from seeping into the interior of the mounting shell along the gap between the moving rod and the mounting shell, and avoiding damage or corrosion of internal components such as the lead screw and threaded block due to water ingress.
[0039] Specifically, a rubber sleeve is fitted onto the outer wall of the movable rod 26 and slides together with the movable rod 26 within the sliding groove 28 and the through hole 29. When the movable rod 26 moves up and down, the rubber sleeve remains in contact with the inner wall of the sliding groove 28 and the inner wall of the through hole 29, filling the gap between the movable rod 26 and the mounting housing 22.
[0040] In some embodiments, the pumping assembly 3 further includes a mounting plate 33, a connecting pipe 34, a fixing plate 35, a rotating sleeve 36, a second motor 37, a driving gear 38, a connecting sleeve 39, and a driven gear 310. The mounting plate 33 is fixedly connected to the top of the baffle 1, and the water pump 31 is fixedly mounted on the top of the mounting plate 33. One end of the connecting pipe 34 is fixedly connected to the water inlet end of the water pump 31. The fixing plate 35 is fixedly connected to the mounting plate 33 and rotatably mounted on the rotating sleeve 36. The top end of the rotating sleeve 36 is rotatably connected to the connecting pipe 34. The second motor 37 is fixedly connected to the fixing plate 35, and the output end of the second motor 37 is fixedly connected to the driving gear 38. The connecting sleeve 39 is fixedly connected to the rotating sleeve 36. The pumping pipe 32 is fixedly connected to the connecting sleeve 39 and communicates with the connecting sleeve 39. The driven gear 310 is fixedly mounted on the connecting sleeve 39, and the driven gear 310 meshes with the driving gear 38.
[0041] The cable trench drainage device of this invention achieves the adjustment of the direction of the water pumping pipe through the cooperation of the second motor, the driving gear and the driven gear. It eliminates the need for manual adjustment of the water pumping port position by entering the narrow cable trench. The flexible adjustment of the direction of the water pumping pipe avoids the problem of water accumulation in dead corners that cannot be reached by the fixed water pumping pipe, and improves the thoroughness and adaptability of the drainage.
[0042] Specifically, when the pumping direction needs to be adjusted, the second motor 37 is started. The second motor 37 drives the drive gear 38 to rotate, which in turn drives the driven gear 310 to rotate. The driven gear 310 drives the connecting sleeve 39 to rotate, which in turn drives the rotating sleeve 36 to rotate relative to the fixed plate 35. Simultaneously, it drives the pumping pipe 32 to rotate around the axis of the rotating sleeve 36, thereby changing the orientation of the inlet of the pumping pipe 32 so that it is aligned with the water accumulation area. The accumulated water enters the connecting sleeve 39 through the pumping pipe 32, and then enters the water pump 31 through the rotating sleeve 36 and the connecting pipe 34, and is discharged by the water pump 31.
[0043] In some embodiments, the pumping assembly 3 further includes an external threaded sleeve 311, an internal threaded sleeve 312, and a filter cover 313. The external threaded sleeve 311 is fixed at one end of the pumping pipe 32 away from the connecting sleeve 39. The internal threaded sleeve 312 is threadedly connected to the external threaded sleeve 311. The filter cover 313 is fixedly connected to the internal threaded sleeve 312 and communicates with the internal threaded sleeve 312.
[0044] The cable trench drainage device of this invention, through the setting of the filter cover, intercepts solid impurities such as mud, sand and debris in the accumulated water, preventing impurities from entering the water pump and the pumping pipe, avoiding water pump impeller jamming or pipe blockage, and ensuring the continuity and stability of the pumping operation; through the threaded connection of the external threaded sleeve and the internal threaded sleeve, a detachable connection between the filter cover and the pumping pipe is realized, simplifying maintenance operations and improving cleaning efficiency; through the fixed connection between the filter cover and the internal threaded sleeve, the stability of the filter cover during the water pumping process is ensured, preventing the filter cover from falling off or shifting due to water flow impact.
[0045] Specifically, before entering the water pump 31 through the pumping pipe 32, the accumulated water first passes through the filter cover 313. The filter cover 313 intercepts solid impurities such as mud and sand in the accumulated water. The filtered water then enters the pumping pipe 32 through the inner threaded sleeve 312 and the outer threaded sleeve 311. When the filter cover 313 needs cleaning, rotate the inner threaded sleeve 312 to separate it from the outer threaded sleeve 311, remove the filter cover 313 together with the inner threaded sleeve 312, clean it, and then tighten and reinstall it.
[0046] In some embodiments, the pumping assembly 3 further includes a drain pipe 314, a support plate 315, and a support frame 316. One end of the drain pipe 314 is connected to the outlet of the water pump 31, and the other end of the drain pipe 314 is connected to the outside. The support plate 315 is fixedly connected to the mounting plate 33 and the drain pipe 314 are fixedly connected. The support frame 316 is fixedly connected to the bottom of the mounting plate 33 and the baffle 1 is fixedly connected.
[0047] The cable trench drainage device of this invention guides the water pumped by the water pump to a designated area outside through the setting of the drainage pipe, avoiding secondary soaking of other areas in the cable trench during the water discharge process; the support plate provides stable support for the drainage pipe, preventing the drainage pipe from shaking, sagging or falling off due to water flow impact or its own weight during the pumping process, thus ensuring the smooth drainage path.
[0048] Specifically, after the water pump 31 starts, it draws the accumulated water into the water pipe 32, pressurizes it, and discharges it from the outlet. The accumulated water is then discharged to a designated area via the drain pipe 314. During the pumping process, the support plate 315 provides support for the drain pipe 314, and the support frame 316 connects the mounting plate 33 and the baffle 1, transferring the overall weight of the pumping assembly 3 to the baffle 1 and ensuring the stable installation of the pumping assembly 3 on the baffle 1.
[0049] In some embodiments, the cable trench drainage device further includes a control unit 4, which is connected to the liquid level probe 21, the first motor 23 and the water pump 31. The control unit 4 is used to receive the liquid level information from the liquid level probe 21 and to control the first motor 23 and the water pump 31 to start according to the liquid level information.
[0050] The cable trench drainage device of this invention realizes automatic reception and processing of liquid level probe detection signals through the setting of control unit, eliminating the need for manual judgment of water depth; through the connection between control unit and first motor, it realizes automatic control of baffle lifting, eliminating the need for manual operation of baffle for area isolation; through the connection between control unit and water pump, it realizes automatic start and stop of pumping operation, eliminating the need for manual handling of mobile water pump to water accumulation area or on-site water pump start.
[0051] Specifically, the liquid level probe 21 detects the water level in real time and transmits the detected liquid level information to the control unit 4. The control unit 4 analyzes and judges the received liquid level information. When the water level reaches a preset height, the control unit 4 sends a start command to the first motor 23, driving the baffle 1 to move downward to form a zone partition; at the same time, it sends a start command to the water pump 31, driving the water pump 31 to pump out and discharge the water through the pumping pipe 32. When the water level drops to a safe height, the control unit 4 controls the first motor 23 to rotate in the opposite direction, driving the baffle 1 to move upward to reset, and controls the water pump 31 to stop working.
[0052] Furthermore, the control unit 4 is existing technology and will not be described in detail.
[0053] In some embodiments, the cable trench drainage device further includes a base 5, which is disposed at the bottom of the frame assembly 2. The base 5 is fixedly connected to the frame assemblies 2 on both sides. The base 5 is used to connect to the bottom wall of the cable trench, and the frame assembly 2 is connected to the side wall of the cable trench. A drainage channel is formed between the base 5, the baffle 1, and the frame assemblies 2 on both sides.
[0054] The cable trench drainage device of this invention provides a stable bottom support for the frame assembly through the base, and at the same time realizes the reliable fixation of the device to the bottom wall of the cable trench, avoiding displacement or overturning of the device under the impact of water accumulation; the fixed connection between the base and the two side frame assemblies forms an integral installation frame, which enhances the structural strength of the device.
[0055] Specifically, the base 5 is fixedly installed on the bottom wall of the cable trench, and the side frame assemblies 2 are fixedly installed on the left and right side walls of the cable trench respectively. The base 5 and the bottom of the side frame assemblies 2 are fixedly connected to form a stable installation frame. The baffle 1 is slidably connected in the guide groove 210 of the side frame assemblies 2. When the baffle 1 moves upward, a drainage channel is formed between the bottom of the baffle 1 and the base 5, allowing water to flow freely in the cable trench. When the baffle 1 moves downward, the bottom of the baffle 1 contacts the base 5, sealing the drainage channel and isolating the cable trench as an independent area. After the water is pumped out by the pumping assembly 3, it flows to other areas or is discharged to the outside through the drainage channel.
