Description

Technical Field

[0001] This utility model relates to the field of generator set technology, specifically to an exhaust structure for an air-cooled gasoline generator set. Background Technology

[0002] With the widespread application of generator sets in various fields, their technology is constantly evolving and improving. To meet diverse usage needs, various types of generator sets have emerged on the market. Common generator sets consist of a power system, control system, noise reduction system, vibration damping system, and exhaust system. However, currently, most generator sets have their fuel tank located above the radiator exhaust vent. Contact between the hot air exhausted from the radiator and the fuel tank can cause the fuel temperature to become excessively high, posing a safety hazard.

[0003] CN 208996848 U discloses an oil tank with a baffle for a generator set, including an oil tank body and a baffle for mounting on the side of the generator set's radiator. However, for users who have already purchased the generator set, directly replacing the oil tank can easily lead to incompatibility with the frame and is also costly. Utility Model Content

[0004] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes an exhaust structure for air-cooled gasoline generator sets that can be installed separately above the engine heat dissipation outlet to prevent hot air from spreading upwards.

[0005] To achieve the above objectives, this utility model provides an exhaust structure for an air-cooled gasoline generator set, including a horizontally arranged main board. The front center of the main board protrudes forward and is irregularly shaped. The rear end of the main board has a downwardly extending rear baffle. The right end of the main board is connected to a vertically arranged right side panel, which extends forward and backward. The right end of the rear baffle is fixedly connected to the right side panel. The right side of the right side panel has a vertically arranged lower connecting lug, which extends left and right. The left end of the protruding part of the main board has an upwardly extending upper connecting lug. Both the lower and upper connecting lugs have mounting holes for fixed connection with the generator set. The front end of the protruding part of the main board has a downwardly extending front baffle. The right end of the protruding part of the main board has a downwardly extending right baffle. A fixing plate is connected between the right baffle and the right side panel, and the left, right, and top sides of the fixing plate are fixedly connected to the right baffle, the right side panel, and the main board, respectively.

[0006] In the above solution, the right flange, right side panel, main board, upper connecting lug, front flange, and rear flange are all integrally formed. After cutting, they can be stamped using a mold; this integral design improves strength.

[0007] In the above scheme: the mounting hole of the upper connecting lug is a strip hole, and the mounting hole of the lower connecting lug is a round hole. The strip hole has a larger connection range, which facilitates installation.

[0008] In the above solution: the left end of the lower connecting lug bends forward into an L-shape, the bent portion on the left side of the lower connecting lug is fixed to the bottom of the right side panel, and the bottom of the right side of the lower connecting lug has an arc-shaped portion located below the bottom of the right side panel. The mounting hole is located on the arc-shaped portion. The L-shape design improves connection stability.

[0009] In the above scheme: the right side panel is provided with a mark for fixing the lower connecting lug, which can locate the lower connecting lug and improve the installation efficiency of the lower connecting lug.

[0010] In summary, the beneficial effects of this utility model are as follows: the diagonally arranged lower and upper connecting lugs can respectively fix the front, rear, left, and right sides, minimizing drilling into the engine assembly and ensuring connection stability. The provided front and rear baffles guide hot air downwards towards the front and rear ends of the main board, creating a downward flow trend, changing the airflow direction, and preventing hot air from diffusing upwards as much as possible. The absence of a windbreak structure on the left side of the main board (front, rear, right, and right surround plates) allows for an exhaust channel on the left side, facilitating hot air exhaust and ensuring efficient ventilation. This technical solution can be separately installed on the engine, saving costs. Attached Figure Description

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

[0016] like Figures 1-3As shown, an exhaust structure for an air-cooled gasoline generator set includes a horizontally arranged main board 1. The front center of the main board 1 protrudes forward in an irregular shape. A rear end flange 2 extends downward at an angle. A vertically arranged right side plate 7 is connected to the right end of the main board 1, extending forward and backward. The right end of the rear end flange 2 is fixedly connected to the right side plate 7. A lower connecting lug 3 is vertically arranged on the right side of the right side plate 7, extending left and right. An upwardly extending upper connecting lug 6 is provided at the left end of the protruding part of the main board 1, extending forward and backward. Both ends of the upper connecting lug 6 are flush with the left side of the protruding part, improving connection and fixation stability. Both the lower connecting lug 3 and the upper connecting lug 6 have mounting holes for fixed connection with the generator set. The mounting holes of the upper connecting lug 6 are strip-shaped, while those of the lower connecting lug 3 are round. The strip-shaped holes have a larger connection range, facilitating installation.

[0017] The front end of the protruding part of the main board 1 is provided with a downwardly extending front baffle 5, and the right end of the protruding part of the main board 1 is provided with a downwardly extending right baffle 4. A fixing plate 8 is connected between the right baffle 4 and the right side panel 7, and the left side, right side and top of the fixing plate 8 are fixedly connected to the right baffle 4, the right side panel 7 and the main board 1 respectively. The right baffle 4, the right side panel 7, the main board 1, the upper connecting lug 6, the front baffle 5 and the rear baffle 2 are all integrally formed. The board body can be cut into the shape shown below. Figure 4 The shape shown is then formed by stamping with a mold, and the one-piece design can improve strength.

[0018] The left end of the lower connecting lug 3 bends forward into an L-shape. The bent portion on the left side of the lower connecting lug 3 is fixed to the bottom of the right side panel 7. The bottom right side of the lower connecting lug 3 has an arc-shaped section located below the bottom of the right side panel 7, and the mounting hole is located on this arc-shaped section. This L-shape design improves connection stability. The right side panel 7 has markings 8 for fixing the lower connecting lug 3, enabling positioning and improving installation efficiency.
