Description

Technical Field

[0001] This utility model relates to the technical field of generator set protection equipment, specifically to a fireproof generator set housing for construction sites. Background Technology

[0002] As a core power equipment in construction projects, the stable operation of construction site generator sets directly affects the construction progress and personnel safety.

[0003] Traditional construction site generator sets typically use a single-layer metal plate structure for their casings. While this provides basic protection, it has significant shortcomings in fire resistance. Firstly, metal plates have high thermal conductivity; when the generator overheats or is ignited by an external fire source, heat can quickly transfer to the outside of the casing, posing a risk of fire spread. Secondly, the single-layer structure cannot prevent the spread of localized flames caused by short circuits or overloads in internal electrical components, easily leading to equipment damage or even personal injury. Furthermore, traditional casings have simplistic heat dissipation designs, often relying on simple ventilation holes in the side walls. However, these holes lack filtration and protection, allowing dust and debris to enter the generator set, affecting operational reliability. Additionally, the metal plates are prone to deformation due to thermal stress under high temperatures, shortening the casing's lifespan. Therefore, a new type of generator set casing that balances fire resistance, heat dissipation, and structural stability is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a fireproof housing for construction site generator sets. Through a double-layer composite fireproof structure, optimized heat dissipation design, and modular connection method, it solves the problems of insufficient fire resistance, low heat dissipation efficiency, and poor structural stability of traditional housings.

[0005] The technical solution provided by this utility model is a fireproof generator set housing for construction sites, including a base, a top cover, and side wall panels. The side wall panels are fixed to the base, and the top cover is fastened to the top of the side wall panels. The side wall panels adopt a double-layer composite structure, including a metal protective plate and a fireproof lining plate arranged sequentially from the outside to the inside. The surface of the metal protective plate is coated with a high-temperature resistant and anti-corrosion coating, and the back of the fireproof lining plate is slidably inserted into the metal protective plate through a buckle. The inner side of the metal protective plate is provided with a flow guiding rib that abuts against the back of the fireproof lining plate. The flow guiding rib is provided with a guide slot that matches the shape of the buckle, and a ventilation interlayer is formed between adjacent flow guiding ribs. The top cover consists of a triangular extension plate and a top-sloping cover plate. The extension plate is provided with a heat dissipation window, and the heat dissipation window integrates multiple layers of flame-retardant metal mesh.

[0006] As a preferred embodiment of this utility model, the fireproof lining is a ceramic fiber board, and the back of the fireproof lining is fixedly connected to the buckle by a flame-retardant adhesive.

[0007] As a preferred technical solution of this utility model, the top and bottom of the metal protective plate are sealed and inserted with the top cover and the base through a stepped connecting platform. In actual use, the connection is fixed by bolts passing through the connecting platform, and flame-retardant silicone sealant is filled at the joint.

[0008] As a preferred technical solution of this utility model, the bottom of the fireproof lining plate abuts against the upper surface of the base, the upper surface of the fireproof lining plate abuts against the inner side of the top cover, and the top cover is provided with a limiting plate on the upper surface of the fireproof lining plate to limit its movement. The limiting plate is perpendicular to the extension plate of the top cover, and there are multiple reinforcing plates between the limiting plate and the extension plate.

[0009] As a preferred embodiment of this utility model, vertical heat dissipation fins are added to the outer surface of the metal protective plate to increase the heat dissipation area.

[0010] As a preferred technical solution of this utility model, the length of the guide rib is less than the height of the side wall panel, and the metal protective plate has a ventilation opening connected to the ventilation interlayer between the heat dissipation fins.

[0011] As a preferred technical solution of this utility model, the bottom of the base is provided with a dust discharge port that communicates with the bottom of the ventilation jacket, the dust discharge port is provided with a slidingly connected baffle plate, and the four corners of the base are provided with adjustable support legs that suspend the base.

[0012] As a preferred embodiment of this utility model, the width and length of the cover plate are both greater than the cross-section of the side wall panel, and the bottom side of the cover plate is rotatably connected to the lower end of the extension plate, while the opposite side is fixed by a buckle.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. High-efficiency fire resistance: The side wall panels adopt a double-layer composite structure of "metal protective plate + ceramic fiber fireproof lining". The fire resistance limit of the ceramic fiber board is ≥2 hours, which can effectively block the spread of internal flames outward. The high-temperature resistant and corrosion-resistant coating of the metal protective plate (temperature resistance ≥800℃) avoids high-temperature deformation. Combined with the multi-layer flame-retardant metal mesh of the top cover, a multi-level fire barrier is formed.

[0015] 2. Optimized heat dissipation design: The ventilation jacket, air guide ribs and heat dissipation fins work together to guide the airflow in an orderly manner and increase the heat dissipation area, thereby reducing the unit's operating temperature; the coordinated design of the ventilation port and ash discharge port ensures ventilation efficiency and facilitates the cleaning of accumulated ash, avoiding blockage that affects heat dissipation.

[0016] 3. Strong structural stability: The side wall panels achieve a sealed connection between the top cover and the base through a stepped connecting platform; the setting of the limiting plate and the reinforcing plate enhances the connection rigidity between the top cover and the fireproof lining.

[0017] 4. Convenience of maintenance: The fireproof lining is slidably connected to the guide ribs by snaps, which is convenient for disassembly and replacement and reduces maintenance costs. Attached Figure Description

[0026] Example 1:

[0027] The present invention provides a fireproof generator set housing for construction sites, comprising a base 1, a top cover 2, and side wall panels 3.

[0028] As per the instruction manual Figures 1-4 As shown, the side wall panel 3 adopts a double-layer composite structure: the outer layer is a metal protective plate 4 (made of Q235 steel plate), with an organic silicone high-temperature resistant and anti-corrosion coating (temperature resistance 800℃); the inner layer is a ceramic fiber fireproof lining board 5 (fire resistance limit 2.5 hours). The back of the fireproof lining board 5 is fixedly connected to the buckle 6 by flame-retardant epoxy resin adhesive. The buckle 6 is slidably inserted into the guide slot 8 on the guide rib 7 on the inner side of the metal protective plate 4. The guide rib 7 is made of aluminum alloy and multiple ribs are evenly distributed along the longitudinal direction of the metal protective plate 4. A ventilation interlayer 9 with a width of 25mm is formed between adjacent guide ribs 7.

[0029] In this invention, the top cover 2 consists of a triangular extension plate 10 (of the same material and thickness as the metal protective plate 4) and an inclined cover plate 11 (of the same material as the metal protective plate 4). A heat dissipation window 12 is provided on the extension plate 10, and three layers of stainless steel flame-retardant metal mesh 13 (90 mesh, 0.5mm thickness per layer) are integrated inside the window. The top and bottom of the metal protective plate 4 are sealed and inserted into the top cover 2 and base 1 via stepped connecting platforms 14, and are externally fixed with M12 bolts. The joints are filled with flame-retardant silicone sealant.

[0030] In this utility model, the bottom of the fireproof lining plate 5 abuts against the upper surface of the base 1, and the upper surface contacts the inner side of the top cover 2. A vertical limiting plate 15 (steel plate thickness 1mm) is welded to the upper surface of the fireproof lining plate 5 on the top cover 2, and a triangular reinforcing plate (steel plate thickness 1mm) is welded between the two.

[0031] In this invention, heat dissipation fins 16 are uniformly arranged longitudinally on the outer surface of the metal protective plate 4. The length of the guide ribs 7 is less than the height of the side wall panel 3. Ventilation openings 17 are opened on the outside of the metal protective plate 4 between the heat dissipation fins 16, and the ventilation openings 17 are located at the upper end of the heat dissipation fins 16.

[0032] In this utility model, a dust discharge port 18 is opened at the bottom of the base 1, an aluminum alloy baffle plate is installed at the dust discharge port 18, and screw-type adjustable support legs are set at the four corners of the base 1, and anti-slip rubber pads are provided at the bottom.

[0033] Working principle

[0034] 1. Fire prevention mechanism: When a local flame is caused by a short circuit or overload inside the unit, the ceramic fiber fireproof lining 5 on the inner wall directly blocks the flame from spreading outward due to its high fire resistance (fire resistance limit of 2.5 hours); the high temperature and corrosion resistant coating (temperature resistance of 800℃) of the outer metal protective plate 4 prevents high temperature deformation; and the multi-layer flame-retardant metal mesh 13 of the top cover 2 further blocks the flame and heat radiation, forming a triple fire protection barrier.

[0035] 2. Heat dissipation process: The heat generated by the unit operation is conducted to the guide ribs 7 through the metal protective plate 4. The guide ribs 7 guide the airflow through the ventilation jacket 9. Some of the heat is directly dissipated to the outside through the heat dissipation fins 16 on the surface of the metal protective plate 4. The other part of the hot airflow enters the ventilation jacket 9 through the vent 17 and is finally discharged from the ash discharge port 18 of the base 1, achieving efficient heat dissipation.

[0036] 3. Structural maintenance: When the fireproof liner 5 needs to be replaced, simply pull out the old liner vertically along the guide slot 8 of the guide rib 7 and insert the new liner; when cleaning the accumulated dust, pour out the dust in the ventilation jacket 9 from the dust discharge port 18 on the base 1, which is easy to operate.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
