Description

Technical Field

[0001] This utility model belongs to the field of electromechanical operation and maintenance of highways, and in particular relates to a quick refueling device for refueling generators in highway tunnel substations. Background Technology

[0002] When constructing highways, tunnels are often excavated to facilitate traffic. Tunnels are also excavated into mountains during mining operations. After tunnel construction, substations are installed at the tunnel entrances or exits to provide lighting and other services for vehicles and pedestrians. These substations are typically connected to the power grid to supply electricity to the equipment inside the tunnel. They are also usually equipped with generators to ensure the equipment can function normally in emergencies.

[0003] Generators typically have their own fuel tanks to generate electricity. When the fuel in the tank is depleted or nearly depleted, it needs to be replenished. Currently, the fuel drums are manually moved to the vicinity of the generator's fuel tank, with the drum's outlet aligned with the tank's inlet, to pour the fuel into the tank. This method of refueling requires manual handling, is time-consuming and inefficient, and poses safety hazards such as fuel leakage and static sparks that could cause the fuel to ignite, thus affecting the safe operation of the tunnel.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0025] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0026] Please see Figure 1-4This utility model provides a quick refueling device for generators in highway tunnel substations, comprising: a base 1, a power supply 2, an oil pump 3, an oil suction pipe 4, an oil delivery pipe 5, a refueling nozzle 6, and multiple movable wheels 7. In this embodiment, four movable wheels 7 are arranged at intervals on the bottom of the base 1. Two of the movable wheels 7 are equipped with brakes. The arrangement of the movable wheels 7 facilitates the refueling device's relocation, and the brakes on the two movable wheels 7 allow the refueling device to be moved to a predetermined position and then fixed there, preventing movement during refueling. The power supply 2, oil pump 3, oil suction pipe 4, oil delivery pipe 5, and refueling nozzle 6 are mounted on the base 1. The power supply 2 can be a battery to power the oil pump 3. One end of the oil suction pipe 4 is connected to the inlet of the oil pump 3, one end of the oil delivery pipe 5 is connected to the outlet of the oil pump 3, and the other end is connected to the refueling nozzle 6. In use, the oil extraction pipe 4 is placed inside the oil drum, the oil nozzle 6 is aimed at the inlet of the generator's oil tank, and then the oil pump 3 is started to transfer the generator oil from the oil drum to the generator's oil tank, thus replenishing the generator's generator oil.

[0027] This embodiment sets up an oil pump 3 and a power supply 2 for supplying power to the oil pump 3 on the base 1. An oil suction pipe 4 is set at the inlet of the oil pump 3 and a delivery pipe is set at the outlet. A refueling gun 6 is set at the end of the delivery pipe away from the oil pump 3. In this way, when replenishing the generator's fuel tank, it is only necessary to move the refueling device to the predetermined position, place the oil suction pipe 4 into the oil drum, and aim the refueling gun at the oil tank to complete the replenishment of the generator fuel. This reduces the step of manually moving the oil drum and improves the refueling efficiency of the generator fuel. At the same time, it also eliminates the safety hazards caused by moving the oil drum.

[0028] A first ball valve 8 and a flow meter 9 can be installed on the oil pipeline 5. The first ball valve 8 is located between the flow meter 9 and the oil pump 3. The ball valve is a fluid control valve, and its core component is a ball with a through hole. By rotating the ball, the fluid can be opened, closed, or regulated. Here, the first ball valve 8 and the second ball valve 10 are used to control the on / off state of the oil pipeline 5. The flow meter 9 is an instrument used to measure the flow rate of fluids (liquid, gas, or steam). Here, it is used to detect the amount of oil being delivered to the oil tank through the oil pipeline 5. In use, the amount of power generation oil to be added to the oil tank can be preset on the flow meter 9. Then, when the power generation oil is being added to the oil tank, once the flow meter 9 detects that the amount of oil delivered through the oil pipeline 5 has reached the target, it can control the first ball valve 8 to stop the delivery of power generation oil to the oil tank. Optionally, when the flow meter 9 detects that the amount of oil being transported through the oil pipe 5 has reached the standard, it can also control the oil pump 3 to stop working, so as to stop it from drawing out the oil for power generation from the oil tank, and thus prevent the continued delivery of the oil for power generation into the oil tank.

[0029] A second ball valve 10 and a flame arrester 11 can also be installed on the oil pipeline 5. The flame arrester 11 is located between the second ball valve 10 and the refueling nozzle 6, and the second ball valve 10 is located between the flow meter 9 and the flame arrester 11. The second ball valve 10 is used to control the opening and closing of the oil pipeline 5. The core principle of the flame arrester 11 is to divide the flame into tiny flame streams through its internal flame-arresting element (usually a metal corrugated plate or metal mesh), and reduce the flame temperature by utilizing heat conduction and heat dissipation effects, ultimately extinguishing the flame. In this embodiment, the flame arrester 11 is a pipeline flame arrester 11. When a fire occurs in the oil tank or oil drum due to static electricity or other reasons, the flame arrester 11 can effectively prevent backfire in the oil pipeline 5 and prevent the fire from spreading. Furthermore, after a fire occurs, the second ball valve 10 blocks the oil pipeline 5 to stop the continued addition of power generation oil to the oil tank.

[0030] The base 1 may also be equipped with a winding wheel 12, which is used to store the oil pipe 5 to facilitate the transfer of the refueling device and to extend the length of the oil pipe 5 so as to transport the oil in the oil drum to the oil tank.

[0031] Please see Figure 1-5 The refueling device also includes a collection component 13 and a storage trough 14 for storing the oil extraction pipe 4. Multiple support columns are mounted on the base 1 for the storage trough 14. The number of support columns can be three or four, but in this embodiment, two support columns are used, spaced apart on the base 1. One side wall of the storage trough 14 is fixedly connected to the two support columns, and the other side wall is connected to the fire extinguisher box 17, thus fixing the storage trough 14 to the base 1. Because of the support columns, there is an installation space between the storage trough 14 and the base 1, within which the power supply 2 and winding wheel 12 can be installed. The bottom of the storage trough 14 is inclined relative to the horizontal plane, and an oil outlet is provided at the lower end of the bottom. The collection component 13 is connected to the oil outlet to collect the generator oil in the storage trough 14. The collection component 13 is an open-top collection box, and a handle can be provided on its outer side wall for easy transport. The storage tank 14 can be equipped with multiple snap-fit ​​components for engaging the oil extraction pipe 4, thereby securing the oil extraction pipe 4 within the storage tank 14. A cover plate can be provided on the top of the storage tank 14 to cover it and prevent dust and other contaminants from falling into the storage tank 14 and adhering to the oil extraction pipe 4, thus affecting its subsequent use. Furthermore, in this embodiment, the bottom of the storage tank 14 is sloped, allowing the collection component 13 to collect the power generation oil adhering to the inside and outside of the oil extraction pipe 4 after use, preventing leakage of the power generation oil.

[0032] The outer surface of the oil outlet can be a square structure, with grooves 15 provided on its two opposite outer side walls. A slider 16, adapted to the groove 15, is provided on the inner side wall of the opening of the collector 13. Specifically, the groove 15 extends from the outer side wall of the oil outlet, and the groove 15 may not penetrate the outer side wall of the oil outlet, thus forming a limiting part between the groove 15 and the outer side wall of the oil outlet, thereby preventing mistaken insertion. The groove 15 can be a T-shaped groove, and the corresponding slider 16 is a T-shaped block, ensuring that the collector 13 can only slide along the extending direction of the groove 15. It is understood that "adapted" in this context means that the size and length of the slider 16 and the groove 15 match, allowing the slider 16 to slide within the groove 15.

[0033] A fire extinguisher box 17 is also installed on the base 1. The fire extinguisher box 17 contains fire extinguishers, fire sand, shovels, and other firefighting equipment, so that personnel can respond immediately in the event of a fire. The outer wall of the fire extinguisher box 17 is equipped with fasteners 18 for securing the fuel nozzle 6. The fasteners 18 can be hook structures, and there can be three of them arranged in a triangle. The hook-like structure of the fastener 18 near the top of the fire extinguisher box 17 faces the top of the fire extinguisher box 17 to secure the handle of the fuel nozzle 6. The hook-like structures of the two fasteners 18 near the bottom of the fire extinguisher box 17 are positioned opposite each other to secure the fuel nozzle 6 near the refueling port. The fasteners 18 secure the fuel nozzle 6, preventing the refueling device from falling to the ground during transport.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
