Abstract
Description
Technical Field
[0001] This application relates to the field of drainage, and more specifically, to an oil depot drainage system. Background Technology
[0002] Currently, domestic oil depots typically have oil tank storage areas. During rainy weather, the working platforms of the oil tanks are washed by rainwater, generating oily wastewater inside the fire dike of the storage area. If this wastewater is not discharged and treated in a timely manner or is mixed with rainwater pipes, it will pollute the local environment.
[0003] In existing technologies, personnel need to arrive on-site and discharge oily wastewater based on experience. However, staff errors or the lack of timely on-site arrival can lead to incorrect or even impossible discharge of oily wastewater from the tank area, polluting the local environment.
[0004] Therefore, how to discharge wastewater in a timely and reasonable manner has become a technical problem that needs to be solved in this field. Utility Model Content
[0005] In view of this, this application proposes an oil depot drainage system to achieve timely and reasonable discharge of wastewater.
[0006] According to this application, an oil depot drainage system is proposed, comprising: a water collection well, wherein a liquid level device is provided in the water collection well; a first drain pipe, wherein a first valve is provided on the first drain pipe; a second drain pipe, wherein a second valve is provided on the second drain pipe; and a control device, wherein the control device includes a time delay controller; wherein the first drain pipe and the second drain pipe are respectively connected to the side wall of the water collection well; one end of the control device is connected to the liquid level device, and the other end is respectively connected to the first valve and the second valve.
[0007] In some embodiments, the liquid level signal generated by the liquid level device is connected to the control device via a first signal transmission line, and the opening and closing signal generated by the control device is connected to the first valve and the second valve via a second signal transmission line and a third signal transmission line, respectively.
[0008] In some embodiments, the control device further includes a control module.
[0009] In some implementations, the start signal generated by the control module is connected to the delay controller, and the delay control signal generated by the delay controller is connected to the control module.

The start signal is used to start the delay controller, and the first opening signal is used to open the first valve.
[0011] In some implementations, when the delay controller starts and reaches a set time, the delay controller generates a delay control signal, and the control module generates a first closing signal and a second opening signal based on the delay control signal. The first closing signal is used to close the first valve, and the second opening signal is used to open the second valve.
[0012] In some embodiments, a drainage ditch is also included, which is connected to the sidewall of the collection well.
[0013] In some embodiments, the first drain pipe is an oily wastewater drain pipe, and the second drain pipe is a rainwater drain pipe.
[0014] In some implementations, the control device is a power distribution control cabinet.
[0015] In some embodiments, both the first valve and the second valve are directly buried, ground-operable electric valves.
[0016] According to the technical solution of this application, by adjusting the delay controller in the control device and the first valve on the first drain pipe and the second valve on the second drain pipe, the initial oily wastewater and the subsequent rainwater in the oil storage tank area can be automatically diverted and discharged, and the entire oil depot drainage system can be made to be controlled without manual intervention.

The control device 1 includes a delay controller 2. The first drain pipe 4 and the second drain pipe 6 are respectively connected to the side wall of the water collection well 8. One end of the control device 1 is connected to the liquid level device 3, and the other end is connected to the first valve 5 and the second valve 7 respectively.
[0025] In some embodiments of this application, the liquid level signal generated by the liquid level device is connected to the control device through a first signal transmission line, and the opening and closing signal generated by the control device is connected to the first valve and the second valve through a second signal transmission line and a third signal transmission line, respectively.
[0026] In some embodiments of this application, the control device further includes a control module.
[0027] In some embodiments of this application, the start signal generated by the control module is connected to the delay controller, and the delay control signal generated by the delay controller is connected to the control module.
[0028] In some embodiments of this application, when the liquid in the collection well reaches a set level, the level device generates a level signal, and the control module generates a start signal and a first opening signal based on the level signal. The start signal is used to start the delay controller, and the first opening signal is used to open the first valve.
[0029] In some embodiments of this application, when the delay controller is started and a set time is reached, the delay controller generates a delay control signal. The control module generates a first closing signal and a second opening signal based on the delay control signal. The first closing signal is used to close the first valve, and the second opening signal is used to open the second valve.
[0030] In some embodiments of this application, a drainage ditch is also included, which is connected to the sidewall of the collection well.
[0031] In some embodiments of this application, the first drain pipe is an oily wastewater drain pipe, and the second drain pipe is a rainwater drain pipe.
[0032] In some embodiments of this application, the control device is a power distribution control cabinet.
[0033] In some embodiments of this application, both the first valve and the second valve are directly buried, ground-operable electric valves.
[0034] The specific implementation methods of this application are further described below with reference to specific embodiments.
[0035] A liquid level device 3 is installed inside the water collection well 8. A first valve 5 is installed on the oily sewage drainage pipe, and a second valve 7 is installed on the rainwater drainage pipe. A power distribution control cabinet is installed outside the water collection well 8, and a time delay controller 2 is installed inside the power distribution control cabinet. The oily sewage drainage pipe and the rainwater drainage pipe are respectively connected to the side wall of the water collection well 8. One end of the power distribution control cabinet is connected to the liquid level device 3, and the other end is connected to the first valve 5 and the second valve 7 respectively.
[0036] During rainy weather, when the liquid level in the collection well 8 reaches the set value (generally submerging the drainage pipe in the collection well 8, but the specific liquid level can be adjusted according to the actual situation), the liquid level signal of the liquid level device 3 in the collection well 8 is sent to the control module in the power distribution control cabinet through the first signal transmission line. The control module generates a start signal and a first opening signal based on the liquid level signal. The start signal is used to start the time delay controller 2 in the power distribution control cabinet, and the first opening signal is used to open the first valve 5. At this time, the oily wastewater generated in the oil storage tank area can be discharged to the oily wastewater treatment equipment through the oily wastewater drainage pipe for timely oil separation treatment. When the time delay controller 2 is started and reaches the set time (generally 10 minutes, but the specific time can be adjusted according to the actual situation), the time delay controller generates a time delay control signal. The control module generates a first closing signal and a second opening signal based on the time delay control signal. The first closing signal is used to close the first valve 5, and the second opening signal is used to open the second valve 7. At this time, the rainwater in the oil storage tank area can be discharged to the downstream rainwater inspection well or rainwater drainage ditch through the rainwater drainage pipe.
[0037] On sunny days, the control module in the power distribution control cabinet defaults to keeping the first valve 5 on the oily sewage drain pipe and the second valve 7 on the rainwater drain pipe closed.
[0038] Both the first valve 5, installed on the oily wastewater drainage pipe, and the second valve 7, installed on the rainwater drainage pipe, are directly buried, ground-operated valves for easy operation. They are generally electrically operated, but in special circumstances (such as power outages, damaged signal transmission lines, or malfunctioning control modules in the power distribution control cabinet), staff can manually open and close the valves. This design allows for timely operation by staff in emergencies, preventing accidents.
[0039] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.
[0040] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
[0041] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
