Technical Field

The invention belongs to the technical field of generators, and particularly relates to a ramp self-adaptive oil tank for a generator set.

Background

The generator set is power supply equipment with wide application, mainly takes diesel oil and gasoline as fuel to generate electric energy after energy conversion, the fuel tank is one of important parts of the generator set, and the reasonable structural design of the fuel tank can provide guarantee for the normal operation of the generator set. The generator set is mostly used as fixed power supply equipment and is arranged on a ground cement foundation, and the equipment is relatively static in the operation process, so that the influence of different oil level states in a fuel tank on the normal operation of the equipment is not considered in the design of the traditional generator set. Along with continuous exploration and expansion of the application field of the generator set, more and more generator sets are applied to mobile scenes such as rail cars, road maintenance vehicles and field engineering vehicles, and therefore the design requirement of a fuel tank is required to meet the oil quantity requirements of the generator set in different states in the moving process. As shown in fig. 1, a chassis oil tank of a conventional generator set is generally formed by welding left and right cross beams with an oil tank bottom plate, a cover plate and the like. The perforated oil tank partition plates are uniformly welded in the oil tank, so that the deformation of the whole oil tank during welding is reduced, and fuel can flow to different compartments in the oil tank through small holes in the oil tank partition plates. When a generator set equipped with such a conventional fuel tank is applied to a mobile scene, if a long ramp is encountered, fuel in the fuel tank flows to a low position of the fuel tank under the action of gravity, and as shown in fig. 2, when the generator set inclines on the ramp, the generator set stops due to insufficient fuel supply, so that the equipment cannot work normally.

The problems are unique to the field of generating sets and are more common in the fields of vehicles and engineering machinery. The invention patent with application number CN201811083156.5, "a diesel fuel pump assembly for gradient adaptive system" provides a solution to ensure the oil supply of the engine by adding a fuel pump with a special structure to the oil circuit system. The generating set generally adopts its engine to take the oil pump fuel feeding certainly, and the additional fuel delivery pump that increases will increase a lot of costs, and in addition, the generating set can customize the oil tank of the different degree of depth according to customer's demand usually, and the fuel delivery pump can't cover the oil tank of all depths, therefore this kind of solution is not applicable to the generating set field. The invention patent with the application number of CN201921779798.9 provides another solution for preventing the diesel generator set from inclining, which controls the fuel state by adjusting the internal structure of the fuel tank to ensure that the fuel level is higher than the oil suction pipe. The scheme is feasible theoretically, but also enables the structure of the oil tank to become complex, the material and the processing cost of the oil tank are greatly improved, the risk of fuel leakage is increased, meanwhile, the scheme needs to manually control the operation panel to change the internal structure of the oil tank when the oil tank inclines, the scheme is not strong in practicability, and the requirement of a mobile generator set for automatically adapting to a ramp cannot be met.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 3, the present embodiment provides a ramp adaptive fuel tank for a generator set, which includes a fuel tank body, and a perforated fuel tank partition plate 6, a non-perforated fuel tank partition plate 11, an oil inlet and return pipe assembly 3, an oil filling pipe assembly 7, and a fuel discharge port 10 that are disposed on the fuel tank body, where the non-perforated fuel tank partition plate 11 is disposed on each of front and rear sides of the oil inlet and return pipe assembly 3, respectively, so as to form a labyrinth compartment at an outer peripheral portion of the oil inlet and return pipe assembly 3, when the generator set is placed horizontally, the labyrinth compartment is in communication with other compartments in the fuel tank body, and when the generator set is tilted, part of fuel oil is retained in the labyrinth compartment when the.

Wherein, the oil tank box comprises oil tank bottom plate 2, oil tank curb plate all around (including left side board 5, right side board 1, preceding curb plate, posterior lateral plate) and oil tank apron 4, sclausura oil tank baffle 11 is full weld with oil tank bottom plate 4, the curb plate 1 or 5 and the oil tank apron 2 seam of oil tank one side sealed to make labyrinth lobe respectively have a intercommunication mouth only in left and right both sides edge.

In this embodiment, the two imperforate tank partition plates 11 are oppositely arranged at the front and rear sides of the oil inlet and return pipe assembly 3, wherein the left end of the first imperforate tank partition plate is hermetically connected with the left side plate of the oil tank, the right end is folded towards the second imperforate tank partition plate to form a first communicating port, the right end of the second imperforate tank partition plate is hermetically connected with the right side plate of the oil tank, and the left end is folded towards the first imperforate tank partition plate to form a second communicating port; in the process that the oil tank inclines back and forth, the two communication ports are changed into an oil inlet and an oil outlet, the height of the oil inlet is always lower than that of the oil outlet, and therefore part of fuel oil always stays in the labyrinth type compartment.

When the oil tank is in a horizontal state, the labyrinth compartments are communicated with the compartments on the front side and the rear side of the oil tank respectively through the communication ports on the left side and the right side; when the oil tank inclines, the fuel on the upper side flows into the labyrinth compartment from the communication port on one side serving as the oil inlet, the fuel on the lower side flows out of the labyrinth compartment from the communication port on the other side serving as the oil outlet, and due to the height difference between the oil inlet and the oil outlet, part of the fuel always stays in the labyrinth compartment.

Add oil pipe subassembly 7 and connect on fuel tank apron 2, for fuel flows out from adding oil pipe subassembly 7 when preventing the oil tank slope, should ensure during the oil tank design add oil pipe subassembly 7 last port is higher than when the oil tank takes place the biggest angle slope, the highest liquid level that the fuel probably reaches. As shown in fig. 6, the upper horizontal line is the line at which the highest level of fuel is possible when the tank is tilted.

The oil tank cover plate 2 is also provided with an oil inlet and return pipe component 3, and the oil inlet and return pipe component 3 generally comprises an oil mass sensor, an oil return pipe and an oil inlet pipe. According to the invention, the tail end of the oil inlet pipe of the oil inlet and return pipe assembly 3 is connected with a section of oil suction hose 31, as shown in fig. 5, the tail end of the oil suction hose 31 is provided with a counterweight oil suction head 32, and when a generator set inclines, the counterweight oil suction head moves to the lower position of the labyrinth compartment under the action of gravity, so that the fuel oil in the labyrinth compartment can be fully used on a ramp by the generator set, and the ramp adaptability of the generator set is further enhanced. In the embodiment, the counterweight oil suction head 32 is preferably a hollow spherical structure with holes, which has a large weight, and can filter large-particle impurities in the fuel oil during oil suction to prevent an oil circuit from being blocked, and meanwhile, the spherical structure can reduce the friction force between the counterweight oil suction head and a bottom plate of a fuel tank, so that the counterweight oil suction head is beneficial to moving to a low position of the fuel oil along with the inclination of the fuel tank, as shown in fig. 7, it can be seen that the oil suction hose 31 and the counterweight oil suction head 32 are in a state along with the inclination of the fuel tank, and such a design is more beneficial to the full use of the fuel oil in the labyrinth compartment on the ramp of the generator.

As shown in fig. 4, the present invention is provided with two fuel discharge ports 10 on the tank body, which are respectively disposed on the side plates near the top and bottom surfaces of the tank. A piece of transparent oil-resistant glass is embedded in each plug of each fuel oil discharge port respectively to observe the position of the liquid level in the oil tank.

As shown in FIG. 3, the biggest difference of the ramp self-adaptive fuel tank for the generator set is that two imperforate fuel tank partition plates 11 form a labyrinth compartment in the middle of the fuel tank, joints of the imperforate fuel tank partition plates 11, a fuel tank bottom plate 4, a side plate 1 or 5 on one side of the fuel tank, a fuel tank cover plate 2 and other parts are all sealed by full welding, so that the labyrinth compartment only has one communicating port at each of the left and right side corners, when the fuel tank is in a horizontal state, the labyrinth compartment is communicated with other compartments of the fuel tank through the communicating ports at the two sides to ensure the liquid level of fuel in each compartment to be consistent, and the flowing state of the fuel in the fuel tank is shown by arrows. When the oil tank is inclined (taking the condition that the generator set is in an uphill state as an example), as shown in fig. 6, fuel at the front part of the labyrinth compartment gradually enters the labyrinth compartment from the communication port at one side and flows to the oil tank at the rear part from the communication port at the other side, when the inclination angle of the oil tank tends to be stable, part of the fuel A91 is stored in the labyrinth compartment, the rest of the fuel B92 gathers at the rear part of the oil tank along with the action of gravity, the fuel A91 in the labyrinth compartment can meet the requirement of the oil quantity required by the small-number normal operation of the generator set, in the practical engineering application, along with the dynamic conversion of the state of the oil tank between the horizontal state and the inclination state, the fuel B92 at the rear part of the oil tank can be continuously supplemented into the labyrinth oil.

The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
