Description

Technical Field

[0001] This utility model relates to the field of diesel generator technology, specifically to a fuel leak prevention mechanism for diesel generator sets. Background Technology

[0002] In the power generation sector, diesel generator sets are key power equipment, and the safety and reliability of their fuel supply system are of paramount importance. Currently, fuel is typically supplied to the fuel tank and generator of oil-fired generators via a flexible hose, with both ends usually secured by wire binding or clamps. While this traditional connection method offers some ease of installation, it has revealed numerous shortcomings in practical applications.

[0003] On the one hand, the uniformity of the tightening force of the wire or clamp is poor, making it difficult to achieve a stable seal. During generator operation, equipment vibration can easily cause the wire to loosen or the clamp to shift, leading to fuel leakage. Especially in high-pressure fuel transportation scenarios, insufficient sealing at the connection point can cause fuel splashing, not only polluting the working environment but also posing a significant fire hazard. On the other hand, wire exposed to oily environments for extended periods is prone to corrosion, and the metal material of the clamp may lose its tightening performance due to fuel corrosion, causing the hose interface to gradually loosen. Furthermore, the hose itself will age and harden due to long-term fuel flushing and changes in ambient temperature. Traditional fixing methods cannot compensate for the deformation caused by hose aging, further exacerbating the risk of fuel leakage. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-3 In this embodiment, a fuel leak prevention mechanism for a diesel generator set is used to increase the stability of the connection between the fuel tank 2 and the generator body 3.

[0023] Specifically, it includes a mounting bracket 1, an oil tank 2, and a generator body 3; the oil tank 2 and the generator body 3 are both installed inside the mounting bracket 1, and a connector 4 is provided on both the oil tank 2 and the generator body 3. The two connectors 4 are connected by a connecting pipe 5; locking components 6 are installed at both ends of the connecting pipe 5, which are used to detachably connect to the two connectors 4 respectively.

[0024] In actual use, the two ends of the connecting pipe 5 are respectively connected to the two connectors 4 by the two locking components 6, thereby improving the stability of the connection between the two ends of the connecting pipe 5 and the two connectors 4 and ensuring the effective supply of fuel.

[0025] In detail, the locking assembly 6 includes a limiting ring 601 installed on the outside of the connecting pipe 5, a docking cylinder 602 movably sleeved on the outside of the connecting pipe 5, an internal thread on the inner circumferential wall of the docking cylinder 602, and an external thread matching the internal thread on the outside of the connector 4; a spring 603 sleeved on the outside of the connecting pipe 5 is assembled between the limiting ring 601 and the docking cylinder 602.

[0026] In actual use, the limiting rings 601 at both ends of the connecting pipe 5 are aligned with the connector 4, and the mating sleeve 602 is inserted so that the internal thread engages with the external thread of the connector 4. The mating sleeve 602 is tightened by the rotating part 604. During the rotation of the mating sleeve 602, the compression spring 603 is compressed, so that the compression spring 603 has a certain elastic potential energy. At this time, the elastic potential energy of the compression spring 603 makes the end of the connecting pipe 5 tightly pressed against the end of the connector 4 facing the connecting pipe 5, forming a seal.

[0027] Furthermore, in order to facilitate the rotation of the docking cylinder 602, in this embodiment, a rotating member 604 is sleeved on the outside of the docking cylinder 602, and the shape of the upper cross section of the rotating member 604 is a regular hexagon.

[0028] In actual installation, the docking cylinder 602 is a regular hexagon. The docking cylinder 602 can be rotated by a wrench or socket tool for easy installation and disassembly.

[0029] Furthermore, in order to increase the heat resistance of the connecting pipe 5, a heat-resistant component 7 is provided on the outside of the connecting pipe 5 in this embodiment. The heat-resistant component 7 includes an asbestos mesh layer 701 wrapped around the outside of the connecting pipe 5, and a sleeve 702 is sleeved on the outside of the asbestos mesh layer 701. The sleeve 702 is made of ceramic fiber.

[0030] In actual installation, a 2-3mm thick asbestos fiber woven mesh is used to tightly wrap the outside of the connecting pipe 5 and is fixed with a high-temperature resistant adhesive, covering the entire exposed part of the connecting pipe 5. A ceramic fiber woven sleeve 702 is selected, with an inner diameter 5-8mm larger than the outer diameter of the connecting pipe 5, and is sleeved on the outside of the asbestos mesh layer 701. Both ends are fixed with metal cable ties and can withstand a maximum temperature of 1000℃.

[0031] Furthermore, the asbestos mesh layer 701 is tightly attached to the surface of the connecting pipe 5. Utilizing the low thermal conductivity and porous structure of the asbestos material, it blocks the heat generated during generator operation from being transferred to the connecting pipe 5, reducing the direct heat action on the hose body and slowing down the aging rate of the hose due to high temperature. The ceramic fiber sleeve 702 is fitted on the outside of the asbestos mesh layer 701 as an outer protective structure. The ceramic fiber can withstand high temperatures, further blocking the conduction of external heat sources to the connecting pipe 5, forming a double heat insulation barrier.
