Description

Zero pollution warning equipment for underground oil pipes in gas stations

This device relates to a zero pollution warning device for the underground oil pipe of a gas station, in particular to a warning device buried under the path of the underground oil pipe of the gas station, which can prevent and prevent the leakage of the underground oil pipe of the gas station under the ground.

Generally, the oil storage tanks and pipelines of gas stations are buried underground, so the oil storage tanks or underground oil pipes are susceptible to leakage due to oxidative corrosion, external damage or other reasons, thereby contaminating the surrounding soil and groundwater. According to research, 46% of oil storage tanks and pipelines that have been buried for more than 10 years will leak, and those who have been buried for more than 15 years will have a leakage probability of 71%.

In a typical gas station, the fuel is stored in an oil tank, and it is matched with an underground oil pipe installed underground to transfer the fuel in the oil tank to each fuel island, and then the distributor is connected to the distribution pump on the fuel island for the convenience of users. The distribution pump draws fuel; however, underground oil pipes may leak due to poor construction or brittle cracks after long-term use. In Taiwan, which is prone to earthquakes, it is easier to rupture due to vibration and cause oil leakage.

In order to detect the leakage of oil in oil storage tanks or underground oil pipes in gas stations, for example, Patent No. 432181 "Operating System and Method for Storage Tanks on the Surface During Operation", which is best selected on the periphery of underground storage tanks and near underground pipelines. Position, drill several gas injection wells / exhaust wells; then add one or more different volatile chemical tracers to the underground storage tanks and pipelines, and simultaneously fill the gas injection wells / exhaustions in the soil filling section near the underground storage tanks and pipelines Gas wells use nitrogen or other gases to flush out the soil gas in the filling portion; observe the occurrence and concentration change of volatile tracer in the soil gas in the extraction well, and whether the presence of volatile tracer in the soil gas in the extraction well is acceptable Identify whether there are leaks in underground storage tanks and pipelines. Another example is the "Soil Gas Sampling Method" of the Republic of China Patent No. 502117 and the "Soil-Gas Sampling Apparatus" of the US Patent No. 5,235,863, which uses a negative pressure vacuum for soil gas sampling; and then by the Republic of China No. I294093 In view of the "parallel soil gas sampling method", it is to obtain a larger amount of soil gas in parallel instead of in series; and based on the "Automated soil gas monitoring chamber" of US Patent 6,598,458, it is Multi-point repetitive sampling is performed with multiple air chambers, and soil gas recovery is performed by the US Patent No. 7,659,123 "In Situ remedial Alternative and Aquifer Properties Evaluation Probe System".

However, in terms of the aforementioned patents, when the oil in the oil storage tank or underground oil pipe has leaked into the soil, the various soil monitoring or detection methods are used to achieve the purpose of early warning and monitoring; at this time, the oil has already been Leakage and contamination of nearby soil can prevent pollution from expanding, but it is still necessary to remediate the contaminated area, which is still a big burden for gas station operators.

In view of this, the inventors of this case have made in-depth discussions on the aforementioned conventional invention problems, and through years of research and development and manufacturing experience in related industries, actively seek solutions, and after long-term research and development, they have successfully developed The equipment "Zero pollution warning device for underground oil pipes in gas stations" has been used to improve various problems in practice.

The purpose of this equipment is to avoid and prevent the problems of oil leakage and pollution of the soil environment caused by various reasons for the underground oil pipes of gas stations under the ground.

In order to achieve the purpose of previous disclosure, this equipment is to provide a zero pollution warning device for the underground oil pipe of the gas station, which is buried under the path of the underground oil pipe of the gas station, and includes: a plurality of pipe grooves, each of which has a channel, and The two ends of the channel respectively form an open end and a connecting end. The channel can accommodate underground oil pipes, and each pipe groove is arranged below the path of the underground oil pipe of the gas station in an inclined manner with the open end slightly higher than the connecting end; a liquid storage tank; It is buried at the junction of each tube groove. The liquid storage tank has an accommodating space and an opening is formed above the accommodating space. The opening is provided with a plurality of connecting portions. The connecting portion may be provided with the connecting end so that each The channel is connected to the storage space of the liquid storage tank, and at least one sensor is provided in the storage space, and the sensor can transmit a signal to an alarm; thereby, when a leak occurs in the local oil pipe, the tube groove The channel can receive the leaked liquid, and because the channel is arranged obliquely, the leaked liquid can flow into the storage space of the liquid storage tank, concentrate the leaked liquid in the liquid storage tank, and send it through the sensor. An alarm is provided, which has the effect of being able to detect at any time whether there is liquid leakage in the liquid storage tank and prevent leakage of underground oil pipes.

In one embodiment, the pipe groove is composed of a bottom plate, a side plate extending upward from both sides of the bottom plate, and a cover, and the bottom plate, the two side plates, and the cover are combined to form a groove that can accommodate the insertion of the underground oil pipe. Road.

In an embodiment, the connecting end of the pipe groove is provided with a connecting flange, and a plurality of connecting holes are provided on the connecting flange; and the connecting portion of the liquid storage tank is provided with a pair of grooves corresponding to the pipe groove, and A plurality of holes corresponding to the connection holes are formed in the grooves. The holes can be set in the grooves through a screw through the connection holes, and the opening ends of the tube grooves are slightly higher than the connection ends. The channel communicates with the containing space of the liquid storage tank.

In one embodiment, the liquid storage tank is further provided with an upper cover, which can close the opening.

In a preferred embodiment, an observation tube is inserted into the liquid storage tank, and the observation tube system protrudes from the upper cover and extends to the ground for daily visual inspection by personnel.

The sensor may be a pontoon sensor, a riot oil level sensor, or an oil and gas sensor.

According to the above, the zero pollution warning device of the underground oil pipe of the gas station of this equipment has the following advantages:
I. This equipment is equipped with a pipe groove under the path of the underground oil pipe of the gas station, and the underground oil pipe is placed in the channel of the pipe groove. When the local oil pipe leaks for various reasons, the leaked liquid can be directly contained In the channel, the soil will not be contaminated.
2. Each pipe groove is arranged below the path of the underground oil pipe of the gas station in an inclined manner with the open end slightly higher than the connection end, and the connection end of each pipe groove is arranged on the connection part of the liquid storage tank, so that each groove The channel is in communication with the storage space of the liquid storage tank; therefore, when the liquid leaking from the local downpipe falls into the channel, the liquid in the channel will flow into the storage space of the liquid storage tank due to the horizontal slope. At this time, the liquid storage tank The sensor inside can send the signal to the siren to send an alarm, and notify the station staff to deal with it.
Avoid continuous leakage.
