Description

Technical Field

[0001] This utility model relates to a refueling device, and more particularly to a skid-mounted refueling device. Background Technology

[0002] Skid-mounted refueling units are short for skid-mounted refueling devices. They are mobile ground refueling devices that integrate oil storage tanks, refueling machines, and video monitoring. They are widely used in bus stops, ports, docks, airports, large construction sites, and internal gas stations of enterprises.

[0003] Currently, in common skid-mounted refueling equipment, various functional interfaces on the tank, such as manholes, gauging ports / oil and gas recovery ports, emergency pressure relief devices, breather valve ports, and level gauge ports, are usually scattered in different positions on the top or side of the tank. When maintenance personnel perform inspections, repairs, or maintenance, they need to frequently move between different positions on the tank. The dispersed operation points increase the complexity and time cost of the operation.

[0004] Manhole covers for skid-mounted refueling tank compartments are typically large and heavy. Most manhole covers on the market are fixed with hinges or bolts, and opening and closing mainly relies on manual lifting. For heavy-duty manhole covers, single-person operation is often laborious and requires considerable physical strength. Furthermore, the lack of effective support or limiting mechanisms to maintain the opening angle when open makes operation inconvenient and poses safety hazards. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides a skid-mounted refueling device.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is as follows: it includes a skid-mounted equipment body, which integrates a No. 1 oil tank and a No. 2 oil tank in parallel. The No. 1 oil tank and the No. 2 oil tank are equipped with an inner and outer tank emergency pressure relief device. Each of the No. 1 oil tank and the No. 2 oil tank is provided with a manhole, an emergency pressure relief device, a breather valve, an oil gauging port / oil and gas recovery port, and a level gauge port. The manhole cover is movably connected to the manhole body through a cover opening mechanism, which is implemented by mechanical transmission under the action of external force.

[0007] Furthermore, the skid-mounted equipment body is set on the ground, and protective dikes are set around the ground. A water collection pit is opened at one corner of the ground, and a sewage pipe that runs through the protective dike is connected to the water collection pit.

[0008] Furthermore, the skid-mounted equipment is equipped with a refueling machine on one side of the No. 1 oil tank.

[0009] Furthermore, the manhole is circular, and the manhole, emergency pressure relief device, breather valve, oil gauging port / oil and gas recovery port, and level gauge port are arranged in a straight line along the length of the skid-mounted equipment body.

[0010] Furthermore, the oil metering port / oil and gas recovery port is implemented by fixing it to an external stainless steel pipeline.

[0011] Furthermore, the level gauge port is implemented by installing a level gauge.

[0012] Furthermore, the opening mechanism includes a well body mounting angle plate fixed to the inner wall of the manhole well body and a cover mounting plate fixed to the inner wall of the manhole cover corresponding to the position of the mounting angle plate.

[0013] Furthermore, the cover opening mechanism also includes a collection plate that is fastened to the well body mounting angle plate. An extension column is machined on the side of the collection plate. The collection plate is movably hinged to a main connecting rod and a second auxiliary connecting rod. One end of the main connecting rod is movably hinged to a gas spring that is movably hinged to the other end on the extension column. The other end of the main connecting rod is movably hinged to a first auxiliary connecting rod. The free ends of the first auxiliary connecting rod and the second auxiliary connecting rod are connected to the cover connecting plate. The cover connecting plate is fastened to the cover mounting plate.

[0014] Furthermore, a swing adjustment rod with its other end hinged to the main connecting rod is also hinged to the plate.

[0015] This utility model discloses a skid-mounted refueling device with a dedicated floor structure that optimizes space utilization and ensures operational stability. By integrating the manhole, gauging port / oil and gas recovery port, emergency pressure relief device, breather valve, and level gauge port, the device reduces the movement distance during maintenance and improves repair efficiency. The mechanical opening mechanism, through linkage transmission and gas spring assistance, reduces the force required to open the manhole cover while ensuring the opening angle is limited, eliminating the risk of accidental opening of the cover.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 As shown in the figure, this embodiment of the skid-mounted refueling device includes a skid-mounted equipment body 1, which integrates a first oil tank 3 and a second oil tank 4 connected in parallel. In the preliminary manufacturing of this embodiment, it is determined that the volume of each of the first oil tank 3 and the second oil tank 4 is 25m³. The tank body is made of steel plate, preferably Q345R. The first oil tank 3 and the second oil tank 4 are equipped with an inner and outer tank emergency pressure relief device 5. Each of the first oil tank 3 and the second oil tank 4 is provided with a manhole 6, an emergency pressure relief device 7, a breather valve port 8, an oil gauging port / oil and gas recovery port 9, and a level gauge port 10. The manhole cover 13 of the manhole 6 is movably connected to the manhole body 14 through a cover opening mechanism 15. The cover opening mechanism 15 is implemented by mechanical transmission under the action of external force. A flame arrestor breather valve is installed on the breather valve port 8. The pressure setting is usually +3kPa / -0.5kPa, but this embodiment does not limit it.

[0023] Unlike conventional skid-mounted refueling devices, the skid-mounted equipment body 1 in this embodiment is set on a concrete floor 11. The construction of the concrete floor 11 helps to provide uniform support for the skid-mounted equipment body 1, improves the stability of the location of the skid-mounted equipment body 1, and helps to avoid safety problems caused by foundation settlement after long-term use. In addition, protective dikes 16 are set around the perimeter of the concrete floor 11, and a water collection pit 12 is opened at one corner of the concrete floor 11. The water collection pit 12 is connected to a sewage pipe that runs through the protective dikes 16. The construction of the sewage pipe is carried out in accordance with current industry regulations. For example, the sewage pipe is made of steel pipe, and a coaxial steel sleeve is set on the outer periphery of the sewage pipe. The space between the sewage pipe and the steel sleeve is filled with asphalt mortar and the inside is filled with asphalt hemp fiber. A wing ring is set on the outside of the steel sleeve to strengthen the connection stability and sealing of the protective dikes 16.

[0024] The skid-mounted equipment body 1 is located on one side of the No. 1 oil tank 3 and is equipped with a refueling machine 2. The refueling machine 2 is an essential key facility for the skid-mounted refueling device.

[0025] In this embodiment, as Figure 1 As shown, the manhole 6 is circular. The manhole 6, the oil gauging port / oil vapor recovery port 9, the emergency pressure relief device 7, the breather valve port 8, and the level gauge port 10 are arranged in a straight line along the length of the skid-mounted equipment body 1. In other words, in this embodiment, the manhole 6, the oil gauging port / oil vapor recovery port 9, the emergency pressure relief device 7, the breather valve port 8, and the level gauge port 10 are integrated and arranged on the top of the skid-mounted equipment body 1. When the operator performs inspection, maintenance, or repair, there is no need to frequently climb and move between different positions on the tank, which is more convenient. On this basis, the oil gauging port / oil vapor recovery port 9 is implemented by fixing an external stainless steel pipeline; the level gauge port 10 is implemented by installing a level gauge.

[0026] like Figure 2 The diagram shown illustrates the actual process flow during use, clearly illustrating the actual usage and external connection relationships of this embodiment, which is helpful for those skilled in the art to understand. However, the specific connection method is not unique to this embodiment.

[0027] The opening mechanism 15 includes a manhole mounting angle plate 17 fixed on the inner wall of the manhole body 14 and a cover mounting plate 18 fixed on the inner wall of the manhole cover 13 corresponding to the position of the mounting angle plate 17.

[0028] The opening mechanism 15 also includes a collection plate 19 that is fastened to the well body mounting angle plate 17. An extension column 20 is machined on the side of the collection plate 19. It should be noted that the side where the extension column 20 is located is the non-connection side between the well body mounting angle plate 17 and the collection plate 19, thereby dividing the connection of the collection plate 19 into regions and optimizing the connection relationship during assembly.

[0029] Based on the above structure, the assembly plate 19 is machined with an extension column 20, on one side of which a main connecting rod 22 and a second auxiliary connecting rod 24 are movably hinged. The position where the main connecting rod 22 is hinged to the assembly plate 19 is located in the middle of the main connecting rod 22, which is S-shaped. The hinged end of the second auxiliary connecting rod 24 is movably hinged to the middle position of the assembly plate 19. One end of the main connecting rod 22 is movably hinged to a gas spring 21, the other end of which is movably hinged to the extension column 20. That is to say, one end of the gas spring 21 is hinged to the main connecting rod 22, and the other end is hinged to... On the extension column 20, the other end of the main connecting rod 22 is movably hinged to the first auxiliary connecting rod 23. The hinge positions of the main connecting rod 22 and the first auxiliary connecting rod 23 are both located on the free ends. The free ends of the first auxiliary connecting rod 23 and the second auxiliary connecting rod 24 are connected to the cover connecting plate 26. The cover connecting plate 26 is fastened to the cover mounting plate 18. The collection plate 19 is also hinged to a swing adjustment rod 25, the other end of which is hinged to the main connecting rod 22. The swing adjustment rod 25 is used to improve the activity stability of the main connecting rod 22.

[0030] When the gas spring 21 extends to drive the main connecting rod 22 to swing around its hinge axis, the main connecting rod 22 and the first auxiliary connecting rod 23 are simultaneously hinged together. The first auxiliary connecting rod 23 and the cover connecting plate 26 move together, and the cover connecting plate 26 simultaneously drives the second auxiliary connecting rod 24 to move. This combined action achieves the driving action of the opening mechanism 15, optimizes the opening and closing form of the manhole cover 13, and reduces the opening and closing force.

[0031] It should be noted that this embodiment shows the case where the opening mechanism 15 is a set. In fact, depending on the weight of the manhole cover 13 and the assembly requirements, those skilled in the art can set up multiple sets of opening mechanisms 15 to further reduce the opening and closing weight and improve the opening and closing stability and durability.

[0032] This embodiment discloses a skid-mounted refueling device with a dedicated floor structure, which optimizes space utilization and ensures operational stability. By integrating the manhole, gauging port / oil and gas recovery port, emergency pressure relief device, breather valve port, and level gauge port, the movement distance during maintenance is reduced, and maintenance efficiency is improved. The mechanical opening mechanism, through linkage transmission and gas spring assistance, reduces the force required to open the manhole cover while ensuring the opening angle is limited, eliminating the risk of accidental cover damage.

[0033] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
