Description

Technical Field

[0001] This utility model relates to the field of diesel generator set technology, and in particular to a diesel generator set with emergency braking protection. Background Technology

[0002] Diesel generator sets, as backup or mobile power sources, are widely used in communications, mining, hospitals, construction, and other fields, and their operational reliability is crucial. Existing diesel generator sets typically have basic functions such as overspeed protection, overheat protection, and underpressure protection. However, under extreme operating conditions, such as governor failure or the fuel control system being stuck at the maximum fuel supply position, the engine may experience a "runaway" phenomenon, where the speed increases sharply and far exceeds the rated speed.

[0003] Existing protective measures largely rely on electronic control systems to cut off the fuel supply. However, in extreme cases where the electronic system itself fails, or the engine fails to stop after fuel is cut off due to the intake of engine oil, combustible gases, etc., there is a lack of a direct, mechanical, forced braking method. This could lead to engine damage due to overspeeding in a very short time, and even cause catastrophic accidents such as connecting rod breakage, crankshaft damage, and engine block rupture, resulting in huge economic losses and safety risks.

[0014] (III) Beneficial Effects

[0015] This utility model provides a diesel generator set with emergency braking protection, which has the following advantages:

[0016] 1. This diesel generator set with emergency braking protection features a braking mechanism. During operation, mechanical braking structures are installed on both sides of the internal generator flywheel. When the power is connected, the miniature push rods on both sides are activated. These push rods move the end brake blocks until they are pressed tightly against the flywheel surface. Friction force is used to forcibly brake the flywheel. The brake blocks are installed using a double-ended screw and a positioning nut, facilitating easy disassembly and assembly by maintenance personnel. The structure is simple, convenient, and practical, preventing engine damage due to overspeeding in a very short time, thus avoiding significant economic losses and safety risks.

[0017] 2. This diesel generator set with emergency braking protection features a movable cooling mechanism. When in use, a cooling fan is installed inside the mounting frame on the top of the generator set casing. The drive motor on one side of the mounting frame can be started, which drives the lead screw on the output end to rotate. This causes the cooling fan, which is threaded onto the surface of the lead screw, to move left and right along the surface of the lead screw under the limitation of a limit rod on one side. This improves the cooling range of the cooling fan and avoids the existence of cooling dead zones, which would prevent the equipment from being adequately cooled and thus affect its normal operation.

[0030] A heat dissipation housing 8 is fixedly connected to one side of the drive motor 601, and the heat dissipation housing 8 is fixedly connected to one side of the mounting frame 5; the heat dissipation housing 8 serves to protect the drive motor 601.

[0031] The top of the mounting frame 5 has ventilation holes, and a dustproof net 9 is installed inside the ventilation holes; the dustproof net 9 serves to block dust.

[0032] A support rod 10 is fixedly connected to the bottom of the generator set housing 1. The support rod 10 is made of stainless steel. The support rod 10 serves to support the generator set housing 1.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: When in use, mechanical braking structures are set on both sides of the internal generator flywheel 3. When the power is turned on, the miniature push rods 403 on both sides are activated. The miniature push rods 403 drive the end brake blocks 401 to move until the brake blocks 401 are pressed tightly against the surface of the flywheel 3.

The brake blocks 401 are installed by the cooperation of the double-headed screw 404 and the positioning nut 405, which also makes it convenient for maintenance personnel to disassemble and install the brake blocks 401 later.
