[0002] During operation, hydropower station equipment may leak oil due to mechanical wear and aging of parts. This oil and water flows through pipelines into the collection well. To prevent oil pollution from entering downstream waterways, manual cleaning of the collection well is currently the standard practice. However, the collection well is poorly ventilated, dark, and damp, posing significant safety risks for manual cleaning. Furthermore, the workload is heavy, the labor intensity is high, and the results of manual cleaning are unsatisfactory. Utility Model Content

[0003] To address the problems of high risks and poor effectiveness of manual cleaning of oil-soil wells in existing technologies, which leads to oil pollution in rivers and waterways and affects environmental safety, this utility model provides an oil-soil cleaning device for water collection wells. After separating the oil-water mixture in the water collection well, the device automatically transports and stores it at a designated location for unified treatment, thereby solving the above problems.

[0004] The technical solution adopted in this utility model is:

[0005] A device for cleaning oil stains from a water collection well includes an oil stain separation device and a transmission and storage control device, wherein the transmission and storage control device is connected to the outlet end of the oil stain separation device.

[0006] The oil-water separation device includes a water storage tank and a pipeline separation mechanism installed on the water storage tank. The pipeline separation mechanism has filter holes. The inlet end of the pipeline separation mechanism is used to connect to the sewage pipe on the side wall of the water collection well. The outlet end of the pipeline separation mechanism is connected to the transmission, storage and control device.

[0008] Furthermore, the pipe separation mechanism includes a pipe support frame disposed on the water storage tank and a loop filter pipe disposed on the pipe support frame, wherein the filter holes are opened at the bottom of the loop filter pipe.

[0009] Furthermore, the pipe support frame includes a transverse support and a longitudinal support, the transverse support and the longitudinal support are fixedly connected, and both ends of the transverse support and the longitudinal support are respectively set on the pool wall of the water storage tank.

[0010] Furthermore, the loop-shaped filter pipe has a multi-stage circulation structure, consisting of multiple straight pipe sections and bends connected in sequence, with pipe clamps connecting adjacent straight pipe sections.

[0011] Furthermore, a filter cloth layer is provided on the pipe separation mechanism, and the filter cloth layer is attached to the outer surface of the pipe separation mechanism and covers the water filter holes.

[0012] Furthermore, the oil tank is equipped with a high oil level sensor and a low oil level sensor. The high oil level sensor is installed at a higher height than the low oil level sensor.

[0015] The beneficial effects of this utility model are:

[0016] This utility model's oil stain cleaning device separates the liquid flowing into the sewage pipe from the side wall of the collection well into water and oil. The water portion is filtered through a filter hole and collected in the storage tank below, while the oily portion is blocked through the filter hole and retained in the pipe separation mechanism. It then enters the oil collection tank of the transmission and storage control device through the outlet of the pipe separation mechanism for collection, thus achieving complete separation of water and oil. This effectively prevents incomplete oil separation from flowing into rivers and lakes, avoiding environmental pollution. Compared to manual cleaning, this utility model's device achieves automatic separation, with good separation effect, saving time and increasing efficiency. The new type of oil collection tank is placed at a low position near the water collection well, while the oil storage tank, which is connected to the oil collection tank via an oil pump, is placed at a higher position on the ground. When the sludge in the oil collection tank reaches a certain level, the oil pump can be started to transport the sludge in the oil collection tank to the higher oil storage tank for storage. Subsequently, relevant personnel can directly process the sludge in the oil storage tank without having to go down into the water collection well, which is safer and more convenient. Moreover, the oil collection tank can operate normally without being affected when the sludge in the oil storage tank is processed, enabling the device to operate continuously and effectively for a long time, reducing the number of shutdowns and restarts, and improving the working efficiency and automation of the device.

The water portion is filtered through the filter holes 2 and collected in the storage tank 1 below, while the oily portion is blocked through the filter holes 2 and retained in the pipeline separation mechanism. It then enters the oil collection tank 11 of the transmission and storage control device through the outlet of the pipeline separation mechanism for collection, thus achieving complete separation of water and oil. This effectively prevents incomplete oil separation from flowing into rivers and lakes, avoiding environmental pollution. Compared to manual cleaning, this utility model's device achieves automatic separation, with good separation effect, saving time and increasing efficiency. The oil collection tank 11 of this utility model is placed in... The oil collection tank 11 is located at a low position near the side wall 16 of the water collection well, while the oil storage tank 12, which is connected to the oil collection tank 11 via the oil pump 13, is placed at the same height as the ground. When the sludge in the oil collection tank 11 reaches a certain level, the oil pump 13 can be started to transport the sludge in the oil collection tank 11 to the oil storage tank 12 at a higher position for storage.

[0027] Example 2

[0028] This embodiment is a further implementation based on Embodiment 1. For details, please refer to... Figure 1 , Figure 2 and Figure 4 In this embodiment, the pipeline separation mechanism includes a pipeline support frame 3 mounted on the water storage tank 1 and a loop-shaped filter pipe 4 mounted on the pipeline support frame 3. Filter holes 2 are located at the bottom of the loop-shaped filter pipe 4. The pipeline support frame 3 is used to support the pipeline separation mechanism on the upper surface of the water storage tank 1. To avoid excessive obstruction affecting the normal filtration of the filter holes 2 in the pipeline separation mechanism, the components of the pipeline support frame 3 can be made of pipe fittings, strip plates, etc., and the material can be wood or steel. The specific selection can be made by those skilled in the art based on the site's humidity and corrosion resistance requirements. The loop-shaped filter pipe 4 allows the mixed liquid to have a longer flow path and a longer residence time in the pipeline separation mechanism, thereby making the oil-water separation more thorough and further improving the separation effect.

[0029] Example 3

[0030] This embodiment is a further implementation based on Embodiment 2. For details, please refer to... Figure 2The pipe support frame 3 includes a transverse support 5 and a longitudinal support 6, which are fixedly connected. Both ends of the transverse support 5 and the longitudinal support 6 are respectively mounted on the wall of the water storage tank 1. Through the cross-arrangement and fixed connection of the transverse support 5 and the longitudinal support 6, the pipe support frame 3 can provide comprehensive support for the entire loop pipe without affecting the normal filtration of the filter holes 2, thereby improving the stability of the device, preventing the pipe separation mechanism from shifting or falling under gravity, and ensuring the long-term stable and effective operation of the device.

[0031] Example 4

[0032] This embodiment is a further implementation based on Embodiment 1. For details, please refer to... Figure 2 , Figure 3 The loop-shaped filter pipe 4 has a multi-stage circulation structure, consisting of multiple straight pipe sections 7 and bends 8 connected sequentially. Adjacent straight pipe sections 7 are each connected by pipe clamps 9. Specifically, the multi-stage circulation structure of the loop-shaped filter pipe 4 can be configured with multiple loop-shaped segmented pipes, such as... Figure 2 As shown, the U-shaped filter pipe 4 starts from the inlet end, and each U-shaped pipe path is set as one of the first-stage circulation structures. Figure 2 The diagram illustrates a loop-shaped filter pipe 4 with five-stage circulation. Those skilled in the art can comprehensively consider the required number of circulation stages based on factors such as the oil content in the water collection well, the pipe flow rate, and the filtration efficiency of the filter holes 2. This loop-shaped filter pipe 4 has better filtration performance, a more compact structural layout, and occupies less space.

[0034] This embodiment is a further implementation based on Embodiment 1. For details, please refer to... Figure 4 A filter cloth layer 10 is installed on the pipeline separation mechanism. The filter cloth layer 10 is attached to the outer surface of the pipeline separation mechanism and covers the water filter holes 2. The mixture in the pipeline is filtered through the water filter holes 2 and the filter cloth layer 10, leaving the oil inside the pipeline, while the water falls into the water storage tank 1 below for collection through the water filter holes 2 and the filter cloth layer 10. The whole process does not require manual intervention. A liquid pump can be installed between the pipeline separation mechanism and the side wall 16 of the water collection well for liquid transportation.

[0035] As a preferred embodiment, the filter cloth layer 10 can be made of geotextile material.

[0036] Example 6

[0037] This embodiment is a further implementation based on Embodiment 1. For details, please refer to... Figure 1 ,

[0038] The oil collection tank 11 is equipped with an oil collection tank high level sensor 14 and an oil collection tank low level sensor 20. The oil collection tank high level sensor 14 is set at a higher height than the oil collection tank low level sensor 20. The oil collection tank high level sensor 14 and oil collection tank low level sensor 20 are used to send signals to start or stop the oil pump 13 after the corresponding liquid level is reached in the oil collection tank 11.

[0039] The high-level oil sensor 14 installed in the oil collection tank 11 sends a signal and starts the oil pump 13 after the oil level in the oil collection tank 11 reaches the limit level. The oil pump 13 lifts and transports the collected sludge oil in the oil collection tank 11 to the storage tank 12 at a higher level for storage, to be processed later. The low-level oil sensor 20 sends a signal to stop the oil pump 13 after the oil pump 13 draws the sludge oil in the oil collection tank 11 to the low level point. After the oil pump 13 has finished transporting the oil, the oil collection tank 11 can continue to collect sludge oil, achieving operation without downtime.

[0040] The oil storage tank 12 is equipped with a high-level sensor 15 and a low-level sensor 21. The high-level sensor 15 is positioned higher than the low-level sensor 21. An alarm 18 is also installed on the oil storage tank 12. The alarm 18 is used to trigger an alarm when the high-level sensor 15 detects that the internal liquid level has reached the limit. The alarm 18 can be a buzzer or similar component. Once the buzzer sounds, the monitoring station staff are alerted to further treat the contaminated oil in the oil storage tank 12, ensuring the continuous and effective operation of the entire system. During the treatment process, the low-level sensor 21 monitors whether the oil level in the tank 12 has reached the low point and sends a corresponding signal, allowing staff to stop the discharge process.

[0041] The specific configuration of each liquid level sensor in this embodiment can be selected from the following models:

[0042] TUF21 series ultrasonic level sensor: used for real-time monitoring of changes in oil level in oil tanks, applicable to fields such as chemical engineering, water conservancy, and storage tanks where level detection is required.

[0043] CR-606 series capacitive oil level transmitter: Features high precision, impact resistance, and easy installation.

[0044] FST700-205 reed switch oil / water level sensor: suitable for measuring the level of oil / water tanks, as well as the level of engineering, machinery, chemical tanks, and sewage tanks in pipelines.

[0045] DLK201 Container Oil Level Sensor: Employs a high-precision sensing core, suitable for liquid level measurement and control in rivers, groundwater, reservoirs, water towers, and containers.

[0046] As a preferred embodiment, a transparent scale 17 is provided on the side wall of the oil storage tank 12, allowing staff to visually observe the oil level inside the tank and quickly determine the liquid level. A drain valve 19 is provided at the bottom of the side wall of the oil storage tank 12, which connects to the inside of the tank. By opening the drain valve 19, a small amount of water mixed in with the sludge can be discharged through sedimentation, achieving separate treatment and further improving the treatment effect.

[0047] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
