Description

Technical Field

[0001] This utility model belongs to the technical field of gas station technology, specifically relating to a safety leak prevention protection device for gas stations. Background Technology

[0002] If a large LNG leak occurs during the operation of a gas station and is not dealt with in time, it will cause a serious accident. LNG is stored at low temperature. Once a leak occurs, it will be heated and flashed to form a flammable vapor cloud of gas and liquid mixture. The toxic arsenic and sulfur heavy components have a density greater than air, so they become heavy gas. If they encounter an ignition source, they may cause fires or even explosions. When an LNG gas station leaks, in the emergency response process, the injured should be rescued first and employees of companies and other units that may be affected by the leak and nearby people should be evacuated in a timely manner to ensure the safety of employees and the public to the greatest extent.

[0022] Please see Figure 1-4 This utility model provides the following technical solution: a safety leak-proof protection device for gas stations, comprising: a gas dispenser 1, a gas pipe 2 installed on one side of the gas dispenser 1, a protective cover 3 abutting against one side surface of the gas dispenser 1, bolts 4 horizontally penetrating and connecting both ends of the protective cover 3, the side walls of the bolts 4 being threaded into the gas dispenser 1, a rubber frame 5 bonded to the inner wall of the opening end of the protective cover 3, a baffle 6 abutting against the surface of the rubber frame 5, rubber strips 7 provided on both sides of the bottom of the baffle 6, the bottom of the rubber strips 7 being snapped into the inner wall of the protective cover 3, an installation pipe 8 provided on the top of the protective cover 3, a gas alarm 9 threadedly connected to the top of the installation pipe 8, an exhaust pipe 10 provided on the back surface of the protective cover 3, a gas valve 11 threadedly connected to the opening end of the exhaust pipe 10, and a gas tank 12 threadedly connected to the bottom outlet surface of the gas valve 11.

[0023] Preferably, the gas dispenser 1, the protective cover 3, and the bolts 4 form a threaded connection structure.

[0024] In practical use, the gas filling pipe 2 is connected to the through groove opened on one side of the protective cover 3, while the protective cover 3 is fixed at the intersection of the gas dispenser 1 and the gas filling pipe 2 using bolts 4.

[0025] Preferably, the protective cover 3, the baffle 6 and the rubber strip 7 form a sliding engagement connection structure, and a rectangular groove is longitudinally opened at the opening end of the protective cover 3, and the shape and size of the groove are adapted to the baffle 6.

[0026] In practical use, pull the baffle 6 upwards to disengage the rubber strip 7 at its bottom from the locked protective cover 3, thereby facilitating the inspection and replacement of the components at the intersection of the gas dispenser 1 and the gas pipe 2 inside the protective cover 3.

[0027] Preferably, the bottom and sides of the protective cover 3 are provided with circular through grooves, and the surface of the through grooves is provided with rubber rings, and the shape and size of the rubber rings are adapted to the gas filling pipe 2.

[0028] In practical use, the through grooves opened on the side wall and bottom of the protective cover 3 make it easy to place the gas pipe 2, while the rubber ring at the intersection of the two can fill the gap at the connection.

[0029] Preferably, the inner wall of the mounting tube 8 is provided with a threaded structure, and the shape and size of the threaded structure are compatible with the bottom connector of the gas alarm 9.

[0030] In practical use, the gas alarm 9 is installed and fixed at the top of the protective cover 3 using the mounting tube 8 at the top of the protective cover 3.

[0031] Preferably, the exhaust pipe 10, the gas valve 11, and the gas tank 12 form a threaded connection structure.

[0033] Working principle: When refueling a vehicle with natural gas, the gas is delivered via the refueling pipe 2 installed on the refueling machine 1. Gas leakage is prone to occur at the connection between the refueling machine 1 and the refueling pipe 2. A through-slot on one side of the protective cover 3 is used to connect the refueling pipe 2, while bolts 4 secure the protective cover 3 at the intersection of the refueling machine 1 and the refueling pipe 2. This creates a small, sealed space at the junction of the refueling machine 1 and the refueling pipe 2. Then, the gas alarm 9 is installed and fixed at the top of the protective cover 3 using the mounting pipe 8. The gas alarm then... 9. Monitor the gas concentration inside the protective cover 3. When the gas concentration inside the protective cover 3 is too high, the gas alarm 9 will start to sound. At this time, the staff can open the gas valve 11 so that the gas inside the protective cover 3 is collected into the gas tank 12 through the connected exhaust pipe 10. This not only avoids the danger caused by the excessive gas concentration inside the protective cover 3, but also allows the leaked gas to be recovered again. At the same time, pull the baffle 6 upward so that the rubber strip 7 at the bottom of it is disengaged from the protective cover 3, thereby facilitating the inspection and replacement of the components at the intersection of the gas dispenser 1 and the gas pipe 2 inside the protective cover 3.
