Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator set technology, specifically to a generator set fuel tank refueling device. Background Technology
[0002] Diesel generator sets are commonly used backup or main power sources, and their fuel tanks are crucial components for ensuring continuous operation. Currently, common diesel generator fuel tanks typically only have a single filler neck at the top. This design has the following drawbacks: when rapid refueling is needed (such as during emergency power supply), the refueling speed is limited, failing to increase the refueling rate. Furthermore, when the refueling mechanism is unable to refuel due to problems such as filter clogging, there is a lack of rapid backup refueling measures, leading to a failure to refuel and affecting the normal operation of the generator. To address these issues, we propose a generator set fuel tank refueling device. Utility Model Content
[0003] The purpose of this invention is to provide a fuel tank replenishment device for generator sets to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fuel tank replenishment device for a generator set, comprising: The fuel tank has two mounting slots on its top wall and two fuel replenishment mechanisms. Each fuel replenishment mechanism includes a mounting base, which is fixedly installed in the mounting slot by multiple fastening bolts. A fuel injection cylinder is fixedly welded to the top wall of the mounting base, and a fuel guide pipe is fixedly installed on the mounting base, communicating with the inner cavity of the fuel injection cylinder. A sealing cap is threaded onto the fuel injection cylinder. A solenoid valve and a flow sensor are fixedly installed on the fuel guide pipe, with the flow sensor positioned below the solenoid valve. A horizontally arranged connecting pipe is fixedly welded between the two fuel guide pipes, positioned above the solenoid valve. Both the solenoid valve and the flow sensor are electrically connected to an external controller.
[0005] Preferably, an isolation cover is fixedly welded to the bottom wall of the mounting base, and both the solenoid valve and the flow sensor are disposed in the inner cavity of the isolation cover.
[0006] Preferably, a pressure balance valve is fixedly installed on the top wall of the fuel tank, and a return oil connector is fixedly installed on the top wall of the fuel tank.
[0007] Preferably, an oil outlet pipe is fixedly installed on the fuel tank, and a drain pipe is fixedly installed on the fuel tank. Valves are installed on both the oil outlet pipe and the drain pipe.
[0008] Preferably, a liquid level observation window is fixedly installed on the fuel tank.
[0009] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention allows for rapid refueling by installing two refueling mechanisms on the fuel tank. When rapid refueling is needed, both refueling nozzles can simultaneously inject fuel, increasing the refueling speed. Furthermore, during daily use, if one refueling nozzle fails to inject fuel due to a malfunction such as a solenoid valve failure, or if the corresponding flow sensor cannot detect fuel flow or the flow rate is slow, an external controller can open the solenoid valve of the other refueling mechanism, allowing fuel to be injected into the fuel tank via its corresponding refueling nozzle. This avoids the problem of insufficient refueling time when only one refueling mechanism is available and malfunctions, greatly improving the convenience of the fuel tank in actual use.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Please see Figure 1-3 This utility model provides a technical solution: a fuel tank replenishment device for a generator set, comprising: A fuel tank 1 has two mounting slots 2 on its top wall. Two fuel replenishment mechanisms 3 are provided on the fuel tank 1. Each fuel replenishment mechanism 3 includes a mounting base 4, which is fixedly installed in the mounting slot 2 by multiple fastening bolts. A fuel injection cylinder 5 is fixedly welded to the top wall of the mounting base 4. A fuel guide pipe 6 is fixedly installed on the mounting base 4, communicating with the inner cavity of the fuel injection cylinder 5. A sealing cap 7 is threaded onto the fuel injection cylinder 5. A solenoid valve 8 is fixedly installed on the fuel guide pipe 6, and a flow sensor 9 is fixedly installed on the fuel guide pipe 6, positioned below the solenoid valve 8. A horizontally arranged connecting pipe 10 is fixedly welded between the two fuel guide pipes 6, positioned above the solenoid valve 8. Both the solenoid valve 8 and the flow sensor 9 are electrically connected to an external controller.
[0014] An isolation cover 11 is fixedly welded to the bottom wall of the mounting base 4. The solenoid valve 8 and the flow sensor 9 are both located in the inner cavity of the isolation cover 11. The isolation cover 11 can prevent oil from contacting the solenoid valve 8 and the flow sensor 9, thereby improving the safety of use.
[0015] A pressure balance valve 12 is fixedly installed on the top wall of the fuel tank 1, and a return oil connector 13 is fixedly installed on the top wall of the fuel tank 1. The pressure balance valve 12 can ensure the pressure balance inside the fuel tank 1.
[0016] A fuel outlet pipe 14 is fixedly installed on the fuel tank 1, and a drain pipe 15 is fixedly installed on the fuel tank 1. Valves are installed on both the fuel outlet pipe 14 and the drain pipe 15.
[0017] A liquid level observation window 16 is fixedly installed on the fuel tank 1, which facilitates observation of the fuel level inside the fuel tank 1.
[0018] Working principle: When in use, this utility model installs two fuel replenishment mechanisms 3 on the fuel tank 1. When rapid fuel replenishment is needed, the two fuel injectors 5 inject fuel simultaneously to increase the fuel replenishment speed. In daily use, if one fuel injector 5 cannot inject fuel due to a malfunction such as a faulty solenoid valve 8, and the corresponding flow sensor 9 cannot detect the flow of fuel or the flow rate is slow, the solenoid valve 8 of the other fuel replenishment mechanism 3 can be opened by an external controller, and fuel will be replenished to the fuel tank 1 through its corresponding fuel injector 5. This avoids the problem of not being able to replenish fuel in time when there is only one fuel replenishment mechanism and it malfunctions, greatly improving the convenience of the fuel tank in actual use.
