Variable frequency diesel generator exhaust structure

Abstract

This utility model discloses an exhaust structure for a variable frequency diesel generator, including a vertically arranged plate. A first mounting hole is provided in the middle of the plate corresponding to the mounting post of the cylinder head heat sink, and the plate abuts against the mounting post, leaving a gap between the plate and the cylinder head heat sink. A bent portion matching the right contour of the cylinder head heat sink is provided on the right side of the plate, with the right end of the bent portion located at the rear of the plate. The right end of the bent portion has a mounting edge extending to the right, directly in front of the hole on the right side of the cylinder head heat sink. A connecting lug is provided on the right side of the mounting edge at a second mounting position, and a second mounting hole is provided on the connecting lug corresponding to the hole. The upper, lower, and right sides of the plate all have rearward-extending flanges for abutting against the cylinder head, forming a cover, allowing air to be exhausted only from the left side of the plate. A clearance notch is provided on the lower right side of the cover, corresponding to the cylinder head, preventing the exhausted hot air from blowing onto the top fuel tank.

Description

Technical Field

[0001] This utility model relates to the field of generator accessories technology, specifically to an exhaust structure for a variable frequency diesel generator. Background Technology

[0002] Diesel generator sets are a common type of power generation equipment, primarily composed of three core modules: the power system, the generator, and the control system. The power system includes a diesel engine, fuel tank, fuel filter, oil filter, radiator or water tank, muffler, and exhaust pipe. Because the air blown out by the radiator tends to diffuse outwards, and heat tends to rise, the temperature of the fuel tank, located at the top, rises. This causes fuel to evaporate easily, producing a large amount of fuel vapor, which increases the pressure inside the fuel tank. This can potentially lead to vapor lock in the fuel lines, resulting in insufficient fuel supply and other problems. Utility Model Content

[0003] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes a variable frequency diesel generator exhaust structure that can prevent the exhaust hot air from blowing onto the top fuel tank.

[0004] To achieve the above objectives, this utility model provides a variable frequency diesel generator exhaust structure, including a vertically arranged plate. The middle part of the plate is provided with a first mounting hole corresponding to the mounting hole post of the cylinder head heat sink, and abuts against the mounting hole post, so that there is a gap between the plate and the cylinder head heat sink. The right part of the plate is provided with a bent part that matches the right contour of the cylinder head heat sink, so that the right end of the bent part is located on the rear side of the plate. The right end of the bent part is provided with a mounting edge extending to the right to the front of the hole on the right side of the cylinder head heat sink. A connecting lug is provided on the right side of the mounting edge corresponding to the second mounting position, and a second mounting hole is provided on the connecting lug corresponding to the hole position.

[0005] The plate extends rearward on its upper, lower, and right sides, and is provided with baffles for abutting against the cylinder head, forming a cover, so that air can only be discharged from the left side of the plate. The lower right side of the cover is provided with a clearance notch corresponding to the cylinder.

[0006] In the above scheme: the bending part bends along an arc shape to form an arc part that matches the outline of the cylinder head heat sink, so that when the hot air from the right side of the cylinder head heat sink blows onto the arc part, it can be turned and then discharged from the left side.

[0007] In the above scheme: the right side ground stop is only set on the mounting edge located above the connecting lug.

[0008] In the above solution, the flange, arc portion, mounting edge, and connecting lug are all integrally formed with the plate body and stamped, making the processing steps simple.

[0009] In the above scheme: the top baffle extends to the right above the mounting edge to avoid hot air blowing upwards as much as possible.

[0010] In summary, the beneficial effects of this utility model are as follows: the designed baffle allows hot air to be discharged only to the left, preventing it from spreading in all directions, especially preventing it from spreading upwards, thus protecting the fuel tank and preventing it from overheating. This, in turn, avoids problems such as increased pressure inside the fuel tank and vapor lock in the fuel line. The designed first mounting hole can be installed on the original mounting hole post on the cylinder head, with a gap to form a channel for hot air to be blown out. The designed bending part can effectively surround the cylinder head heat sink, improving the heat insulation effect. The designed connecting lug can serve as a second fixing structure to ensure installation stability. Attached Figure Description

[0015] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0016] like Figures 1-4 As shown, a variable frequency diesel generator exhaust structure is used to cover the exhaust port of the engine cylinder head. It includes a vertically arranged plate 2. The middle part of the plate 2 is provided with a first mounting hole corresponding to the mounting hole post 3 of the cylinder head heat sink 1 provided in the cylinder head, and abuts against the mounting hole post 3, so that there is a gap between the plate 2 and the cylinder head heat sink 1. The right part of the plate 2 is provided with an arc part 6 that matches the contour of the cylinder head heat sink 1, and the right end of the arc part 6 is provided with a mounting edge 7 that extends horizontally to the front of the hole on the right side of the cylinder head heat sink 1. The right side of the mounting edge 7 is provided with a connecting lug 8 corresponding to the second mounting position 4, and the connecting lug 8 is provided with a second mounting hole corresponding to the hole position.

[0017] The upper, lower, and right sides of the plate 2 are all provided with flanges 9 for abutting against the cylinder head, forming a cover, so that air can only be discharged from the left side of the plate 2. The lower right side of the cover is provided with a clearance notch 10 corresponding to the cylinder.

[0018] The mounting edge 7 located above the connecting lug 8 is also provided with a forward-extending baffle 9. The baffle 9, the arc portion 6, the mounting edge 7, and the connecting lug 8 are all integrally formed with the plate body 2 and stamped together. The top baffle 9 extends to the right above the mounting edge 7 to minimize the upward blowing of hot air.
