The device includes a base with a flame-retardant cover at the center of its upper surface. Refueling machines are mounted on both sides of the flame-retardant cover. An oil storage tank for supplying oil to the refueling machines is located inside the flame-retardant cover. An oil filling pipe is connected to the top of the oil storage tank, passing through the flame-retardant cover. A filter assembly is located at the top of the oil filling pipe. The filter assembly includes a lower housing and an upper housing. A sliding sleeve is fixedly installed at the bottom center of the lower housing. A sliding column is slidably mounted through the center of the sliding sleeve. A connecting sleeve is fitted on the top of the sliding column. A filter screen is arranged around the side wall of the connecting sleeve. A limiting plate is located at the bottom of the sliding column, and a tension spring connects the limiting plate and the sliding sleeve. This invention can filter gasoline entering the oil storage tank, effectively reducing the probability of scale buildup inside the tank and improving the quality of the gasoline. Furthermore, the filter screen in the filter assembly is easy to install and remove, facilitating maintenance and replacement.

[0003] The aforementioned patented explosion-proof skid-mounted refueling device has the following shortcomings: although it is easy to disassemble the filter screen, the filter screen needs to be removed every time it is cleaned, which means that each cleaning operation requires a series of steps such as stopping the machine, disassembling, and reinstalling, which is time-consuming, labor-intensive, and inefficient. Therefore, it is necessary to design an explosion-proof skid-mounted refueling device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an explosion-proof skid-mounted filling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof skid-mounted filling device includes a base, a flame-retardant cover fixedly connected to the top of the base, an oil storage tank fixedly connected to the bottom inner wall of the flame-retardant cover, an oil filling pipe fixedly connected to the top of the oil storage tank, the oil storage tank communicating with the oil filling pipe, the oil filling pipe passing through the top of the flame-retardant cover, a sealing cap provided at the top of the oil filling pipe, a sealing ring provided at the bottom of the sealing cap, a support plate fixedly connected to the bottom inner wall of the oil filling pipe, a filter screen provided at the top of the support plate, a round tube fixedly connected to the top of the filter screen, a drive rod passing through the sealing cap, the drive rod rotatably connected to the sealing cap, a handle fixedly connected to the top of the drive rod, a mounting plate fixedly connected to the bottom of the drive rod, and a brush provided at the bottom of the mounting plate. This technology employs a brush to scrub the surface of the filter screen. When dirt adheres to the filter screen, simply rotating the handle causes the brush to turn, cleaning the screen. Installing the sealing cover also limits the filter screen's position, preventing it from rotating or falling off, thus ensuring its stability. This effectively solves the problem raised in the background technology: although the filter screen is easy to disassemble, each cleaning requires removing it, leading to a series of steps such as stopping the machine, disassembling, and reinstalling, which is time-consuming, labor-intensive, and inefficient. This technology achieves simple operation, allowing cleaning without stopping the machine or removing the filter screen, significantly reducing cleaning time and ensuring work efficiency.

[0007] Preferably, the top of the filter screen is fixedly connected to two positioning tubes, and a positioning rod is provided inside the positioning tube. The top of each of the two positioning rods is fixedly connected to the bottom of the sealing cover.

[0008] Preferably, an elastic sealing ring is fixedly connected to the inner wall of the oil injection pipe, the elastic sealing ring is disposed on the top of the support plate, and a handle is fixedly connected to the inner wall of the round pipe.

[0009] Preferably, a connecting pipe is fixedly connected to one side of the oil injection pipe, and a valve is provided on the connecting pipe.

[0010] Preferably, two positioning plates are fixedly connected to the outer wall of the top end of the oil injection pipe. A circular hole is provided on each positioning plate, and a fixing rod is installed inside the circular hole. A fixing plate is fixedly connected to the top of the fixing rod. Both fixing plates are fixedly connected to a sealing cap. Insertion holes are provided on both the positioning plates and the drive rod, and insertion rods are installed inside the insertion holes. A square plate is fixedly connected to the outer wall of the insertion rod. Guide rods pass through both ends of the square plate. The guide rods are fixedly connected to the positioning plates, and the square plate is slidably connected to the guide rods. A spring is sleeved on the guide rod, and the spring is located on the side of the square plate away from the positioning plates. By setting up the insertion rod, positioning plates, insertion holes, and fixing rods, when the insertion rod is inserted into the insertion holes on the positioning plates and fixing rods, the position of the fixing rod can be limited, thus fixing the position of the fixing rod and the sealing cap. Furthermore, when installing the sealing cap, the positioning rod can be inserted into the positioning tube, thus limiting the position of the filter screen. This achieves the technical effect of facilitating the installation and disassembly of the sealing cap and filter screen, and making it convenient to remove the filter screen for deep cleaning later.

[0011] Preferably, both of the two insertion rods are fixedly connected to a pull rod on the side that is far apart from each other.

[0012] Preferably, a fuel dispenser is provided on both sides of the flame-retardant cover, and the oil storage tank supplies fuel to the fuel dispensers.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing a brush to scrub the surface of the filter screen, when dirt adheres to the filter screen, simply rotating the handle causes the brush to rotate, thus cleaning the filter screen. Installing the sealing cover also limits the filter screen's movement, preventing it from rotating or falling off, ensuring its stability. This effectively solves the problem raised in the background technology that, although the filter screen is easy to disassemble, each cleaning requires removing it, leading to a series of steps such as stopping the machine, disassembling, and reinstalling, which is time-consuming, labor-intensive, and inefficient. This technology achieves simple operation, allowing cleaning without stopping the machine or removing the filter screen, significantly reducing cleaning time and ensuring work efficiency.

[0015] 2. By setting up an insertion rod, positioning plate, insertion hole, and fixing rod, when the insertion rod is inserted into the insertion hole on the positioning plate and fixing rod, the position of the fixing rod can be limited, thus fixing the position of the fixing rod and the position of the sealing cover. When installing the sealing cover, the positioning rod can also be inserted into the positioning tube to limit the position of the filter screen. This achieves the technical effect of facilitating the installation and removal of the sealing cover and filter screen, and making it convenient to remove the filter screen for deep cleaning later.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7An explosion-proof skid-mounted filling device includes a base 1, a flame-retardant cover 2 fixedly connected to the top of the base 1, an oil storage tank 3 fixedly connected to the bottom inner wall of the flame-retardant cover 2, an oil filling pipe 4 fixedly connected to the top of the oil storage tank 3, the oil storage tank 3 and the oil filling pipe 4 communicating, the oil filling pipe 4 passing through the top of the flame-retardant cover 2, a sealing cap 5 provided at the top of the oil filling pipe 4, a sealing ring provided at the bottom of the sealing cap 5, a support plate 6 fixedly connected to the bottom inner wall of the oil filling pipe 4, a filter screen 7 provided at the top of the support plate 6, a round tube 8 fixedly connected to the top of the filter screen 7, a drive rod 9 passing through the sealing cap 5, the drive rod 9 rotatably connected to the sealing cap 5, a handle 10 fixedly connected to the top of the drive rod 9, and a mounting plate 11 fixedly connected to the bottom of the drive rod 9, with a brush 12 provided at the bottom of the mounting plate 11. Because it employs a brush to scrub the surface of the filter screen, when dirt adheres to the filter screen, simply rotating the handle causes the brush to turn, thus cleaning the filter screen. Installing the sealing cover also limits the filter screen's position, preventing it from rotating or falling off, ensuring its stability. This effectively solves the problem raised in the background technology that, although the filter screen is easy to disassemble, each cleaning requires removing it, leading to a series of steps such as stopping the machine, disassembling, and reinstalling, which is time-consuming, labor-intensive, and inefficient. Therefore, it achieves simple operation, cleaning without stopping the machine or removing the filter screen, greatly shortening the cleaning time and ensuring work efficiency.

[0026] In this utility model, two positioning tubes 13 are fixedly connected to the top of the filter screen 7. Positioning rods 14 are provided inside the positioning tubes 13. The tops of the two positioning rods 14 are fixedly connected to the bottom of the sealing cover 5. During installation, the positioning rods 14 are inserted into the positioning tubes 13. After the sealing cover 5 is installed, the filter screen 7 will not shift when the mounting plate 11 and the brush 12 are rotated to clean the filter screen 7.

[0027] In this utility model, an elastic sealing ring 15 is fixedly connected to the inner wall of the oil injection pipe 4. The elastic sealing ring 15 is set on the top of the support plate 6. A handle 16 is fixedly connected to the inner wall of the round pipe 8. When the filter screen 7 is installed, the filter screen 7 and the round pipe 8 will squeeze the elastic sealing ring 15, and the filter screen 7 and the round pipe 8 will fit tightly with the elastic sealing ring 15 to seal.

[0028] In this utility model, a connecting pipe 17 is fixedly connected to one side of the oil injection pipe 4, and a valve is provided on the connecting pipe 17. Oil can be injected into the oil storage tank 3 through the connecting pipe 17.

[0029] In this invention, two positioning plates 20 are fixedly connected to the outer wall of the top end of the oil injection pipe 4. A circular hole 21 is provided on the positioning plate 20, and a fixing rod 19 is installed inside the circular hole 21. A fixing plate 18 is fixedly connected to the top of the fixing rod 19. Both fixing plates 18 are fixedly connected to sealing caps 5. Insertion holes 22 are provided on both the positioning plate 20 and the drive rod 9. An insertion rod 23 is installed inside the insertion hole 22. A square plate 24 is fixedly connected to the outer wall of the insertion rod 23. Guide rods 25 pass through both ends of the square plate 24. The guide rods 25 are fixedly connected to the positioning plate 20, and the square plate 24 is slidably connected to the guide rods 25. A spring 26 is sleeved on the guide rod 25, and the spring 26 is positioned away from the square plate 24. On one side of the positioning plate 20, insert the rod 23 into the insertion hole 22 on the positioning plate 20 and the fixing rod 19 to limit the position of the sealing cover 5. The sealing cover 5 is then placed on the oil injection pipe 4 for installation. By setting the rod, positioning plate, insertion hole and fixing rod, when the rod is inserted into the insertion hole on the positioning plate and the fixing rod, the position of the fixing rod can be limited, thus fixing the position of the fixing rod and the position of the sealing cover. When installing the sealing cover, the positioning rod can also be inserted into the positioning tube to limit the position of the filter screen. This achieves the technical effect of facilitating the installation and disassembly of the sealing cover and the filter screen, and making it convenient to remove the filter screen for deep cleaning later.

[0030] In this invention, each of the two insertion rods 23 is fixedly connected to a pull rod 27 on the side that is far apart from each other.

[0031] In this utility model, a fuel dispenser 28 is provided on both sides of the flame-retardant cover 2, and the oil storage tank 3 supplies oil to the fuel dispenser 28.

[0032] Working principle: When installing the filter screen 7, place the filter screen 7 on the tray 6. During the insertion of the filter screen 7, it will come into contact with the elastic sealing ring 15. Press the filter screen 7 and the round tube 8 to lower them, so that the filter screen 7 and the round tube 8 can be tightly fitted to the elastic sealing ring 15 for sealing. Adjust the position of the two positioning tubes 13 so that the two positioning tubes 13 are parallel to the two insertion rods 23. Insert the positioning rod 14 into the positioning tube 13. Pull the pull rod 27 to move the two pull rods 27 away from each other. During the movement of the pull rod 27, the pull rod... Pull rod 27 will move insert rod 23, which in turn will move square plate 24. Square plate 24 will move along guide rod 25 and will also compress spring 26, causing spring 26 to contract and remove insert rod 23 from insertion hole 22 on positioning plate 20. Fixing rod 19 will be inserted into round hole 21. Releasing pull rod 27 will cause the contracted spring 26 to extend, allowing insert rod 23 to be inserted into insertion hole 22 on positioning plate 20 and fixing rod 19. This limits the position of fixing rod 19 and allows for installation. After installing the sealing cap 5, the sealing ring at the bottom of the sealing cap 5 fits tightly against the top of the fuel injection pipe 4 to create a seal. Once installed, the sealing cap 5 will not rotate, and the positioning rod 14 will restrict the position of the positioning tube 13, thus restricting the position of the filter screen 7, preventing it from rotating or falling off. After installation, the connecting pipe 17 can be connected to the fuel injection pipe to inject fuel into the fuel tank 3. The fuel is filtered through the filter screen 7, effectively reducing the probability of scale buildup inside the fuel tank and improving fuel efficiency. After a period of use, the gasoline inside the oil tank can be cleaned by turning the handle 10, which will drive the drive rod 9 to rotate, which in turn will drive the mounting plate 11 to rotate, which in turn will drive the brush 12 to rotate and clean the surface of the filter screen 7, removing the dirt covering the surface of the filter screen 7. When the filter screen 7 needs to be removed for deep cleaning, pull the lever 27 again to remove the insert 23 from the insertion hole 22, remove the sealing cover 5, and pull the handle 16 to remove the filter screen 7.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
