Description

Underground oil pipeline warning and monitoring device

This creation is about a warning and monitoring device for underground oil pipes, especially a warning and monitoring device for oil pipes buried underground in a gas station.

Domestic gas stations mostly use underground storage tanks to store gasoline and diesel for sale. The storage tank of the gas station pumps the oil to the tanker for supply through the underground oil pipe. At present, about 90% of the storage tanks used in domestic gas stations are made of steel, and more than 60% of underground oil pipes or connectors are made of metal; however, underground oil pipes or connectors may be brittle due to poor construction or long-term use. As for leakage, in Taiwan, where earthquakes are prone to occur, it is more likely to rupture due to vibration and cause oil leakage.

Current pollution prevention and control require underground storage tank systems to perform leak detection. The detection techniques include: tank tightness testing, underground wells for oil and gas or oil slick inspections, or analytical instruments to detect the degree of contamination of the soil by oil products. When an abnormality is detected, it means that the oil product of this gas station has leaked to the outside of the underground storage tank system, and when the oil product leakage is actually detected, the underground storage tank system may have leaked for a period of time, which has already caused serious pollution to the environment. . The remediation of oil spills is also a major project, which may include the remediation of soil and groundwater, which requires inexpensive costs, and more importantly, the related environment has been harmed.

In order to detect oil leakage in oil storage tanks or underground oil pipes in gas stations, as in Patent No. I679614 "The Creation of Zero Pollution Warning for Underground Oil Pipes in Gas Stations", pipe grooves are installed in the path of underground oil pipes, and the underground oil pipes are installed in the pipeline. In the pipe trough, when there is a leak in the local lower tubing, the channel of the pipe trough can receive the leaked liquid, the leaked liquid can flow into the containing space of the liquid storage tank, and the leaked liquid can be concentrated in the liquid storage tank It also has the function of detecting whether there is liquid leakage in the liquid storage tank at any time and preventing the leakage of underground oil pipes by using the sensor to send out an alarm.

However, the aforementioned patents need to set up several additional pipe grooves, and then flow through the oil groove to the reservoir to achieve the purpose of early warning and monitoring. Before construction, a channel must be reserved to erect the pipe grooves, which makes it difficult for the existing industry to replace and cannot be popularized. ; And the erection cost of the pipe trough is high, and the maintenance is not easy.

In view of this, the inventor of this case has made an in-depth discussion on the aforementioned conventional invention problems, and has actively sought solutions through years of experience in R&D and manufacturing in related industries to improve various conventional problems.

The main purpose of this creation is to avoid and prevent the problems of oil leakage and soil pollution caused by the underground oil pipes of the gas station under the ground for various reasons; and the installation cost is low, and it can be used in both old and new gas stations. Underground tubing laid by the body.

In order to achieve the aforementioned purpose, this creation is to provide an underground oil pipeline warning and monitoring device, which includes: an oil pipe with an oil pipeline inside, the oil pipe is covered with a protective pipe, and there is a gap between the protective pipe and the oil pipe; at least one guide The flow tube has a connecting end and an open end, the connecting end is connected to a proper position of the protective tube and communicates with the gap; a liquid storage tank has a containing space, and the open end of the flow guide tube is connected It is arranged in the liquid storage tank and penetrates the containing space; and, the warning monitoring unit is arranged outside, and at least one sensor is arranged in the containing space, and the sensor is connected with the warning monitoring unit line, if the sensor When the device detects the leaking liquid from the above-mentioned liquid storage tank, the warning monitoring unit will issue a warning and cut off the power supply of the oil conveying motor, and stop the oil supply, so as to avoid the pollution of the environmental soil caused by the continued leakage.

In one embodiment, an adapter seat is provided at the joint of each of the oil pipes, and a gap is formed between the adapter seat and the protective tube, and the diversion tube is connected to the gap and the containing space of the liquid storage tank.

The protective tube can be a PU hose, a polyurethane hose, a polyurethane hose or a silicone hose.

The sensor can be a float sensor, an explosion-proof oil level sensor or an oil gas sensor.

According to the above, the underground oil pipeline warning monitoring device of this creation has the following advantages: 1. This creation is to wrap a protective pipe directly on the outside of the underground oil pipe. When the oil pipe leaks due to various reasons, the leaked liquid can directly flow through the gap through the draft tube and enter the liquid storage tank without contaminating the soil. 2. Since each oil pipe system is directly connected to a liquid storage tank, when the sensor in the liquid storage tank is sent to the warning monitoring unit, the oil pipe can be directly repaired or replaced, eliminating the inspection operation of individual oil pipes. Reduce maintenance costs. 3. The oil pipe of this creation can be directly exchanged with the old oil pipe, and there is no need to reserve a channel to erect the pipe groove, the cost is low, and both new and old gas station bodies can be used.

In order to achieve a more complete disclosure of the technical content for the purpose of creation, I will elaborate on the following content, and please also refer to the disclosed diagram and drawing number:

Please refer to Figure 4, which is a schematic diagram of the implementation state of this creation under the ground of a gas station. When the underground oil pipe 10 is configured to transport the oil storage tank 12 to the gas station body 40, the draft tube 16 can be set at the lowest of the oil pipe 10 At this point, when a leak occurs in the oil pipe 10, the leaked liquid will quickly fall into the containing space 181 of the liquid storage tank 18 from the draft tube 16 by the inclination. At this time, the sensor 32 detects that there is For the leaked liquid, the warning monitoring unit 30 will issue a warning and cut off the power supply of the oil conveying motor, and stop the oil supply, so as to avoid the pollution of the environmental soil caused by the leakage.
