Description

Technical Field

[0001] This invention relates to the field of corridor cleaning devices, and more specifically to a flow channel cleaning device with water-oil separation and its method of use. Background Technology

[0002] Hydropower station spillway equipment generally uses hydraulic systems for drive and control. During long-term operation, these systems are susceptible to accidental oil leaks, such as aging seals and pipe ruptures. Leaking hydraulic oil can rapidly spread along the spillway's galleries, gates, and hydraulic structure channels. If not handled promptly and effectively, this can lead to oil slicks accumulating on the gallery floor, causing slips and falls, corroding metal pipes and concrete structures within the galleries, and even entering the spillway area with the water flow, causing downstream water pollution. All of this seriously impacts the safe operation of the hydropower station and the ecological environment.

[0003] Currently, the treatment of oily wastewater in the spillway corridor is mainly done manually: workers operate water pumps to collect oily wastewater from the pipe trenches, while traditional oil-absorbing felts are used to simply absorb and remove oil stains from the pressure pipes and trench surfaces. However, due to the generally narrow space of the spillway corridor and the presence of numerous crisscrossing pipe trenches, the above-mentioned manual treatment method suffers from a core technical problem: it cannot quickly and effectively control the spread of pollution caused by hydraulic oil leaks. On the one hand, manual operation is inefficient, making it difficult to complete large-scale cleaning operations in the early stages of oil pollution, leading to the continuous spread of oil pollution. On the other hand, manual cleaning is ineffective, and oil stains in dead corners of pipe trenches and at the bottom of pressure pipes are difficult to completely remove, allowing residual oil stains to continue to spread and cause secondary pollution. In addition, manual operation in the slippery corridors poses a high safety risk, and it is impossible to simultaneously complete the integrated treatment of oil sludge flushing, wastewater suction, and water-oil separation, which is insufficient to meet the actual needs of emergency cleaning and daily maintenance of the hydropower station's spillway corridor. Summary of the Invention

[0004] The main objective of this invention is to provide a flow channel cleaning device with water-oil separation and its usage method, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: it includes a vehicle body, an oil-water separation device and a cleaning tank mounted on the vehicle body, a filter chamber is provided in the container of the oil-water separation device, and a first filter and a second filter are provided in sequence for filtration in the filter chamber, and both the first filter and the second filter are provided with absorbent cotton. The container is equipped with a suction pump on the outside. The outlet of the suction pump is connected to the filter chamber through a pipe. The suction port is connected to a suction pipe for suctioning sewage in the corridor. The cleaning box contains cleaning components for flushing and cleaning the corridor.

[0006] Preferably, the first frame in the first filter is provided with a cover plate, and a sewage pipe is fixed on the cover plate. The outlet of the suction pump is connected to the sewage pipe through a pipe. The first frame has a first side plate at the hollowed-out area around the first frame, and the bottom of the first frame is fixed inside the second filter by a first clip. Multiple through holes are evenly distributed on the first side plate; The absorbent cotton is clipped and fixed to each of the first side plates.

[0007] Preferably, the second frame of the second filter has a second side plate at the hollowed-out area around it, and the bottom of the second frame is fixed in the filter chamber by a second clip. Multiple through holes are evenly distributed on the second side plate; The absorbent cotton is clipped and fixed to each of the second side plates.

[0008] Preferably, a water pump is also provided outside the container, with one end of the water pump connected to an external water pipe and the other end used to connect to a cleaning device.

[0009] Preferably, the cleaning box is equipped with a rotating winding drum, and the winding drum is equipped with a flexible hose for winding. The cleaning components consist of a nozzle with a brush head and a connecting rod. The nozzle is connected to the water pump via a hose.

[0010] Preferably, the cleaning box is equipped with rotating sealing plates on both sides.

[0011] Preferably, the mounting bracket of the vehicle body is equipped with multiple rollers at the bottom.

[0012] Preferably, a water outlet pipe is provided at the bottom of the filter chamber, and the water outlet pipe is connected to an external collection box through a pipe.

[0013] Preferably, the cleaning chamber is equipped with a sewage tank and a clean water tank, and the filter chamber is connected to the sewage tank through a pipe, so that the sewage filtered by the filter chamber enters the sewage tank; The clean water tank is used to store cleaning fluid for cleaning corridors.

[0014] A method for using a flow channel cleaning device with water-oil separation, comprising the following steps: S1. Move the entire device to the area that needs cleaning, install the cleaning parts, pull the hose on the winding drum to extend or retract to the appropriate length, connect the external water pipe, and start the water pump to clean the corridor through the nozzle with the brush head. S2. The wastewater collected after cleaning is collected in the pipe trench. After cleaning is completed, the suction pipe is connected and the suction pump is started to suck the wastewater in the pipe trench through the suction pipe. S3. The pumped-up sewage undergoes dual filtration through the first and second filters to fully remove oil and particulate matter from the sewage. The filtered water is then discharged from the outlet pipe. S4. After cleaning, the first and second side panels can be removed by opening the container, and the absorbent cotton can be taken out for cleaning or replacement for the next use.

[0015] This invention provides a flow channel cleaning device with water-oil separation and its usage method, with the following advantages: 1. This device integrates oil stain flushing and cleaning with rapid suction of oily wastewater, simultaneously washing the corridor floor and side walls and recycling wastewater, preventing the long-term accumulation of oily wastewater after cleaning. It eliminates the safety hazard of slipping on wet floors at the source, while significantly reducing the corrosion of corridor facilities by wastewater, effectively extending the service life of the corridor infrastructure.

[0016] 2. A multi-stage conical filtration structure with nested first and second filters is adopted to form a layered filtration system: the first filter prioritizes the interception of large particles such as mud, sand, and debris, preventing clogging of subsequent pipelines and filter components from the source; the second filter further filters fine impurities and floating oil, achieving efficient water-oil separation. The filtered effluent can directly meet discharge standards or be used for secondary cleaning, which reduces wastewater treatment costs and saves water resources.

[0017] 3. Both the side plates of the filter and the absorbent cotton adopt a flexible snap-fit ​​fixing structure, which can be quickly disassembled and assembled without complicated tools; the first and second filters are connected by snap-fit ​​bolts, and a buffer gap is reserved between them, which not only ensures filtration stability, but also facilitates individual disassembly and maintenance. This design makes the cleaning and replacement of the absorbent cotton extremely simple, significantly shortens the equipment downtime for maintenance, and reduces long-term operation and maintenance costs.

Detailed Implementation

[0019] Example 1 like Figures 1-6 As shown, a flow channel cleaning device with water-oil separation includes a vehicle body 1, an oil-water separation device 2 and a cleaning tank 3 mounted on the vehicle body 1. The oil-water separation device 2 has a filter chamber 241 in the container 24, and a first filter 22 and a second filter 23 are arranged in sequence for filtration in the filter chamber 241. Both the first filter 22 and the second filter 23 are provided with absorbent cotton. The container 24 is equipped with a suction pump 26. The outlet of the suction pump 26 is connected to the filter chamber 241 through a pipe. The suction port is connected to a suction pipe for suctioning sewage in the corridor. The cleaning box 3 contains cleaning components for flushing and cleaning the corridor.

[0020] The vehicle-mounted main unit 1 can move flexibly within the corridor, carrying the cleaning device to the area to be cleaned. It uses cleaning components to flush away oil stains on the corridor floor and simultaneously uses a suction pipe to pump the cleaned oily wastewater into the receiving tank 24. This allows for rapid removal of oily wastewater and accumulated water from the corridor, preventing wastewater from accumulating on the floor for extended periods, avoiding slippery surfaces that could pose safety hazards, and reducing corrosion of the corridor facilities. The pumped wastewater is filtered sequentially through the first filter 22 and the second filter 23, forming a multi-stage filtration structure that filters impurities and oil stains in the wastewater in layers. The first filter 22 intercepts large particles such as mud, sand, and debris to prevent clogging of subsequent structures. The second filter 23 further filters out finer impurities and floating oil, ensuring that the filtered wastewater meets discharge standards or can be reused.

[0021] Preferably, the first frame 224 in the first filter 22 is provided with a cover plate 222 on top, and a sewage pipe 21 is fixed on the cover plate 222. The outlet of the suction pump 26 is connected to the sewage pipe 21 through a pipe. The first frame 224 is provided with a first side plate 221 at the hollowed-out parts around it. The bottom of the first frame 224 is fixed in the second filter 23 by a first clip 223. Multiple through holes are evenly distributed on the first side plate 221. The absorbent cotton is clipped and fixed on each of the first side plates 221.

[0022] The first filter 22 has a conical structure, with the first frame 224 being an integral frame structure. The bottom of the first frame 224 is a fixed sealing plate, and the sides and top are open. The four sides of the open areas have grooves. The first side plate 221 is a flexible perforated plate that can be slightly bent and fixed in the grooves on the first frame 224. At the same time, the absorbent cotton is also tightly attached to the first side plate 221 and fixed in the grooves. The snap-fit ​​structure facilitates the disassembly and assembly of the first side plate 221 and the replacement of the absorbent cotton later. The absorbent cotton in the first filter 22 can perform preliminary filtration of sewage. The first locking block 223 is fixed to the bottom of the first frame 224 and is fixed to the second filter 23 by bolts, thus creating a gap between the first filter 22 and the second filter 23 for buffering sewage with different filtration levels.

[0023] Preferably, the second frame 232 in the second filter 23 has a second side plate 231 at the hollowed-out area around it, and the bottom of the second frame 232 is fixed in the filter chamber 241 by a second clip 233; multiple through holes are evenly distributed on the second side plate 231; and the absorbent cotton is clipped and fixed on each of the second side plates 231.

[0024] The second filter 23 has a conical structure and fits around the outside of the first filter 22. The second frame 232 is an integral frame structure with a fixed sealing plate at the bottom and openwork around the sides and top. The openwork areas around the sides have grooves. The second side plate 231 is a flexible perforated plate that can be slightly bent and locked into the grooves on the second side plate 231 for fixation. Simultaneously, the absorbent cotton is also tightly fitted against the second side plate 231 and locked into the grooves for fixation. This locking structure facilitates the disassembly and assembly of the second side plate 231 and the replacement of the absorbent cotton later. The absorbent cotton in the second filter 23 further filters the wastewater. The second locking block 233 is fixed to the bottom of the second frame 232 and secured to the filter chamber 241 with bolts to prevent it from moving under the impact of wastewater.

[0025] Preferably, the container 24 is also equipped with a water pump, one end of which is connected to an external water pipe, and the other end is used to connect to the cleaning component. The cleaning container 3 is equipped with a rotating winding drum 32, and the winding drum 32 is equipped with a retractable hose; the cleaning component is a nozzle with a brush head and a connecting rod, and the nozzle is connected to the water pump through the hose.

[0026] A water pump connects to an external water pipe, allowing external cleaning water to be sprayed from the nozzles. The nozzles, equipped with brush heads and connecting rods, can be used to scrub and clean the corridor floor and side walls. A retractable hose allows the nozzles and connecting rods to be moved to cover a larger area.

[0027] Preferably, the cleaning box 3 has rotating sealing plates 31 on both sides. The sealing plates 31 can cover the items inside the cleaning box 3. The mounting bracket 11 of the vehicle body 1 is provided with multiple rollers 12 at the bottom. The rollers 12 enable the vehicle body 1 to slide, thereby enabling the cleaning device to move.

[0028] Preferably, the bottom of the filter chamber 241 is provided with a water outlet pipe 25, which is connected to an external collection box via a pipeline. The filtered wastewater discharged from the filter chamber 241 can be transported to the outside for collection and reuse or directly discharged.

[0029] Preferably, when venturing deep into the corridor or without external water support, the cleaning tank 3 can be equipped with a wastewater tank and a clean water tank, as well as a portable power source to power the water pump and suction pump 26. The filter chamber 241 is connected to the wastewater tank via a pipe, and the wastewater filtered by the filter chamber 241 enters the wastewater tank. The clean water tank is used to store the cleaning solution for corridor cleaning. The water pump can draw water from the clean water tank for cleaning, and the pumped wastewater enters the wastewater tank for storage.

[0030] Example 2 like Figures 1-6 As shown in Example 1, a method for using a flow channel cleaning device with water-oil separation is further illustrated, and the method steps are as follows: S1. Move the entire device to the area that needs cleaning, install the cleaning parts, pull the hose on the winding drum 32 to extend or retract to the appropriate length, connect the external water pipe, and start the water pump to clean the corridor through the nozzle with the brush head. S2. The wastewater collected after cleaning is collected in the pipe trench. After cleaning is completed, the suction pipe is connected and the suction pump 26 is started to suction the wastewater in the pipe trench through the suction pipe. S3. The pumped-up sewage undergoes dual filtration through the first filter 22 and the second filter 23, which effectively removes oil and particulate matter from the sewage. The filtered water is discharged from the outlet pipe 25. S4. After cleaning, the first side panel 221 and the second side panel 231 can be removed by opening the container 24, and the absorbent cotton can be taken out for cleaning or replacement for the next use.
