Description

Technical Field

[0001] This utility model relates to the technical field of generator sets, and in particular to a prefabricated outdoor diesel generator set engine room structure and generator set. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. Currently, the most common generator sets are diesel generator sets. As core power supply equipment, generator sets cover industrial and infrastructure applications.

[0003] To facilitate the protection and maintenance of generator sets, existing generator sets typically include a housing structure. For example, a low-space, high-safety generator set power room, disclosed in patent publication CN220815098U, includes a power room and a retractable walkway railing mechanism. The walkway railing mechanism comprises a walkway railing and a retraction control mechanism. The walkway railing is rotatably connected to the power room. The retraction control mechanism includes a support frame fixed to the top of the power room, a reducer and a take-up / delivery reel mounted on the support frame, a reel auxiliary rod between the reducer and the reel, a handle auxiliary rod, a handle for controlling the reducer, a rocker arm between the handle auxiliary rod and the handle, and a traction rope between the take-up / delivery reel and the walkway railing. In use, the operator pushes the handle auxiliary rod according to their height to adjust the handle's position. Once the handle is in position, the operator operates the handle to control the reducer to rotate, lowering the walkway railing. Maintenance and inspection of the power supply system within the power room can then be performed from the walkway.

[0004] However, the power room structure in the relevant technology is an integrated structure, that is, the power room is formed by welding the plates together. The power room is heavy and inconvenient to transport, disassemble, maintain and clean. Utility Model Content

[0005] To address the problems of existing integrated power room structures that are inconvenient for transportation, disassembly, maintenance, and cleaning, this utility model provides a prefabricated outdoor diesel generator set's power room structure and generator set.

[0006] The first objective of this utility model is to provide a prefabricated outdoor diesel generator set engine room structure, which adopts the following technical solution:

[0007] A prefabricated outdoor diesel generator set engine room structure includes a housing body and a walkway railing mechanism installed on the housing body. The housing body includes a base, end plates, side plates, and a top cover plate that can be detachably connected to each other. The base, side plates, end plates, and top cover plate are interconnected to form an installation cavity for installing a hybrid power generator set. The top cover plate includes multiple connecting plates and multiple surface plates, which are welded together. The surface plates are provided with reinforcing parts.

[0008] The above technical solution modularizes the housing into base, end plates, side plates, and a top cover, facilitating transportation, disassembly, maintenance, and cleaning / sand washing. Damage to any component—base, side plates, end plates, or top cover—requires replacement of the corresponding part, eliminating the need to replace the entire housing. This modular design is particularly important for equipment with high sealing requirements. Furthermore, the reinforcing section increases the bending stiffness of the panel, resulting in higher structural strength. The corrugated texture of the reinforcing section reduces the risk of thermal deformation during welding of the panel and connecting plates, preventing dents and ensuring the flatness of the top, thus preventing water accumulation. The walkway railing mechanism supports operators for maintenance and repair, contributing to the long-term stable operation of the generator set.

[0009] Preferably, the reinforcing part is raised, and multiple reinforcing parts are provided. The multiple reinforcing parts (142) are evenly distributed, and the multiple reinforcing parts make the surface panel form a wave-like pattern.

[0010] Through the above technical solution, multiple reinforcing parts further ensure the stability of the panel. The reinforcing parts increase the surface area of ​​the panel, and the heat generated by the generator set will reach the panel through thermal rise. The design of the reinforcing parts can help dissipate heat.

[0011] Preferably, the base is further provided with reinforcing ribs, which are used to improve the structural strength of the base.

[0012] The above technical solutions are used to strengthen the structural strength of the base and ensure its load-bearing capacity.

[0013] Preferably, the side panel has an access port that extends through the side panel. The access port is covered by an access door, which is used to open or close the access port. The access door is hinged to the side panel or the end panel.

[0014] The above technical solution allows for the opening or closing of the inspection port by driving the inspection door to rotate, thus facilitating maintenance by operators.

[0015] Preferably, the walkway handrail mechanism includes a walkway tread hinged to the building body and a handrail hinged to the walkway tread; a rotating rod is passed through the walkway tread and detachably connected to the walkway tread; a first hinge seat is provided on the base and detachably connected to the base; a first hinge shaft is provided on the first hinge seat, passing through the first hinge seat and the rotating rod, and the first hinge shaft is fixedly connected to the first hinge seat; the handrail includes a guardrail frame hinged to the walkway tread and a guardrail bar provided on the guardrail frame; a second hinge seat is provided on the walkway tread, and a second hinge shaft is provided on the second hinge seat, passing through the second hinge seat and the rotating rod, and the second hinge shaft is fixedly connected to the second hinge seat.

[0016] The above technical solution hinges the walkway tread to the base via a rotating rod, hinge seat one, and a first hinge shaft, allowing the walkway tread to rotate along the first hinge shaft. The handrail is hinged to the walkway tread via a rotating rod, hinge seat two, and a second hinge shaft, allowing the handrail to rotate along the second hinge shaft. Thus, driving any part of the handrail will drive the walkway tread to rotate.

[0017] Preferably, the walkway treads are made of aluminum.

[0018] The above technical solutions utilize aluminum, which has a density only one-third that of steel, making it lighter. This lightweight design simplifies handling and assembly processes, making it suitable for applications requiring rapid assembly. Furthermore, aluminum has a melting point of approximately 660°C and does not release toxic gases, meeting fire safety standards and enhancing safety.

[0019] Preferably, at least one hinge seat is provided, and the number of the first hinge shaft, rotating rod, second hinge seat, and second hinge shaft corresponds to the number of the first hinge seat.

[0020] The above technical solution, with more than one hinge seat 1, first hinge shaft, rotating rod, hinge seat 2, and second hinge shaft, helps to make the walkway treads rotate more stably on the base and the handrails rotate more stably on the walkway treads.

[0021] Preferably, the top cover plate is provided with a hinge seat three, and an auxiliary rod is connected to one end of the guardrail away from the railing. The auxiliary rod is detachably connected to the guardrail, and a connecting rod is hinged to the auxiliary rod. The two ends of the connecting rod are respectively hinged to the auxiliary rod and the hinge seat three.

[0022] The above technical solution, through the hinge seat three, auxiliary rod, and connecting rod, limits the rotation range of the handrail and walkway treads, making the entire rotation process more stable. The rotating rod is detachably connected to the walkway treads, the hinge seat one is detachably connected to the base, and the auxiliary rod is detachably connected to the guardrail, allowing the treads, handrails, connecting rods, and hinge seat three to form multiple modular components. This enables the walkway handrail mechanism to be quickly assembled and disassembled, further facilitating transportation, disassembly, maintenance, and cleaning / sand washing.

[0023] Preferably, the walkway handrail mechanism further includes an elastic element, which is a torsion spring. The elastic element is sleeved on the first hinge shaft, one end of the elastic element abuts against the hinge seat, and the other end of the elastic element is wrapped around the rotating rod.

[0024] Through the above technical solution, the torsion spring can provide force in the rotation direction of the walkway tread. The torsion spring is suitable for hinged structures that are frequently opened and closed, can make efficient use of space, and provide a labor-saving effect.

[0025] The second objective of this utility model is to provide a hybrid power generator set, which adopts the following technical solution:

[0026] A generator set includes the machine room structure described in any one of the above.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. By modularly disassembling the building body and walkway handrail mechanism, it is easy to transport, disassemble, maintain and clean the sand. If any part is damaged, the corresponding part can be replaced instead of replacing the entire building body or walkway handrail mechanism.

[0029] 2. The reinforcing section improves the bending stiffness of the panel, making the panel structurally stronger. The reinforcing section creates a wave-like texture on the panel, which helps reduce the risk of thermal deformation during welding of the panel and connecting panels, prevents dents in the structure, and ensures the flatness of the top of the structure, thereby preventing water accumulation. Multiple reinforcing sections further ensure the stability of the panel. The reinforcing section increases the surface area of ​​the panel, and the heat generated by the generator set will reach the panel through thermal rise. The design of the reinforcing section can help dissipate heat.

[0030] 3. The walkway treads are made of aluminum. Due to the lightweight nature of aluminum, the handling and assembly process can be simplified, making it suitable for rapid assembly. In addition, aluminum has a melting point of about 660°C and does not release toxic gases, meeting fire safety regulations and improving safety.

[0031] 4. Torsion springs can provide force in the direction of rotation of walkway treads. Torsion springs are suitable for hinged structures that are frequently opened and closed, which can make efficient use of space and provide a labor-saving effect. Attached Figure Description

[0041] The following will refer to the appendix in the embodiments of this utility model. Figures 1 to 7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] Example 1

[0043] A prefabricated outdoor diesel generator set engine room structure, referring to Figure 1 It includes a rectangular box 1 and a walkway railing mechanism 2 installed on the box 1. The box 1 is used to install and protect the generator set, and the walkway railing mechanism 2 is used to support operators to carry out maintenance and repair.

[0044] Specifically, refer to Figure 2 and Figure 3 The room body 1 includes a base 11, end plate 12, side plate 13, and top cover 14, all of which can be detachably connected to each other. The room body 1 is formed by the mutual connection between the base 11, end plate 12, side plate 13, and top cover 14. That is, any two parts of the base 11, end plate 12, side plate 13, and top cover 14 can be detachably connected, so as to facilitate disassembly and assembly. In addition, the base 11, end plate 12, side plate 13, and top cover 14 are all made of high-strength metal materials, specifically stainless steel, to ensure the supporting strength of each component or room body 1.

[0045] Among them, reference Figure 2 The base 11 is rectangular in shape and is welded from multiple steel pieces. Reinforcing ribs 3 are also provided on the base 11 to improve its structural strength. The reinforcing ribs 3 are fixedly connected to the base 11 by welding to enhance its structural strength and ensure its load-bearing capacity.

[0046] Reference Figure 3 and Figure 4 The end plate 12 has a cross-section in the shape of []. The end plate 12 is distributed perpendicular to the base, and its shape is compatible with the end of the base. The end plate 12 is located at one end of the base and is bolted to the base 11. That is, the end plate 12 and the base 11 are assembled by bolt connection. There are two end plates 12, which are located near the two ends of the base 11 and are distributed opposite each other.

[0047] Reference Figure 3 and Figure 4The side plate 13 is rectangular in shape, perpendicular to the base 11, and distributed along the length of the base 11. The long side of the side plate 13 is bolted to the base 11, and the short side of the side plate 13 is bolted to the end plate 12. An inspection port 4 is provided on the side plate 13. The inspection port 4 is rectangular and distributed along the height of the base 11, extending through the side plate 13. An inspection door 15 is provided on the top cover of the inspection port 4. The inspection door 15 is used to open or close the inspection port 4. The inspection door 15 is hinged to either the side plate 13 or the end plate 12, so that the inspection port 4 can be opened or closed by driving the inspection door 15 to facilitate maintenance by operators. Two side plates 13 are also provided, one on each of the two long sides of the bottom.

[0048] Reference Figure 3 and Figure 4 The top cover plate 14 is also rectangular in shape and is distributed along the length of the base 11. The top cover plate 14 is bolted to the side plates 13 and the end plates 12. The top cover plate 14 includes multiple connecting plates and multiple surface plates 141, which are welded together. The connecting plates have different shapes. The surface plates 141 are provided with reinforcing parts 142, which are elongated and distributed along the width of the top cover plate 14. In this embodiment, the reinforcing parts 142 are stamped and protrude outwards. The reinforcing parts 142 improve the bending stiffness of the surface plates 141, making the structural strength of the surface plates 141 higher. The reinforcing parts 142 also make the surface plates 141 form a wave-like texture, which helps to reduce the risk of thermal deformation when welding the surface plates 141 and the connecting plates, prevents the room body 1 from having notches, and ensures the flatness of the top of the room body 1, thereby preventing water accumulation. Multiple reinforcing parts 142 are provided, and the multiple reinforcing parts 142 are evenly distributed along the length direction of the top cover plate 14. The multiple reinforcing parts 142 further ensure the stability of the surface plate 141. The reinforcing parts 142 increase the surface area of ​​the surface plate 141. The heat generated by the generator set will reach the surface plate 141 through thermal rise. The design of the reinforcing parts 142 can assist in heat dissipation.

[0049] In addition, refer to Figure 3 and Figure 4The mounting cavity for the generator set is formed by the interconnection of the base 11, two side plates 13, two end plates 12, and the top cover 14. The modular design of the housing 1, consisting of the base 11, end plates 12, side plates 13, and top cover 14, facilitates transportation, disassembly, maintenance, and cleaning. If any component of the base 11, side plates 13, end plates 12, or top cover 14 is damaged, only the corresponding component needs to be replaced; the entire housing 1 does not need to be replaced. This modular design is particularly important for equipment with high sealing requirements. Furthermore, the walkway railing mechanism 2 supports operators for maintenance and repair, contributing to the long-term stable operation of the generator set.

[0050] Looking back Figure 1 and Figure 2 The walkway handrail mechanism 2 is located on one long side of the building 1. There are two walkway handrail mechanisms 2, located on opposite sides of the building 1. The two sets of handrail components 22 allow operators to perform maintenance from multiple angles, facilitating the repair of different components of the generator set. During maintenance, operators can access the required inspection location by opening the walkway handrail mechanism 2 and then open the inspection door 15 to perform the maintenance.

[0051] Specifically, refer to Figure 1 and Figure 2 The walkway handrail mechanism 2 includes a walkway step 21 hinged to the building body 1, a handrail 22 hinged to the walkway step 21, and an elastic element 31.

[0052] Reference Figure 1 The walkway tread 21 is rectangular and distributed along the length of the base 11. One long side of the walkway tread 21 is hinged to one long side of the base 11. The walkway tread 21 is made of aluminum. Aluminum has a density that is only 1 / 3 that of steel, making it lighter. Lightweighting simplifies the handling and assembly process, making it suitable for rapid assembly. In addition, aluminum has a melting point of about 660°C and does not release toxic gases, meeting fire safety regulations and improving safety.

[0053] Furthermore, refer to Figure 2 and Figure 5A rotating rod 23 is mounted on the walkway tread 21. The rotating rod 23 is a long rod distributed along the width of the walkway tread 21, extending beyond the two long sides of the walkway tread 21. The rotating rod 23 is detachably connected to the walkway tread 21 by bolts. A hinge seat 24 is mounted on the base 11, detachably connected to the base 11 by bolts. One end of the rotating rod 23 extends into the hinge seat. A first hinge shaft 25 is mounted on the hinge seat 24, passing through the hinge seat 24 and the rotating rod 23. The first hinge shaft 25 is fixedly connected to the hinge seat 24, thereby hinged the walkway tread 21 to the base 11, allowing the walkway tread 21 to rotate along the first hinge shaft 25.

[0054] Reference Figure 1 and Figure 5 The handrail 22 includes a guardrail frame 221 hinged to the walkway tread 21 and guardrail bars 222 mounted on the guardrail frame 221. The guardrail frame 221 is a rectangular frame distributed along the length of the walkway tread 21. A second hinge seat 26 is provided on one long side of the walkway tread 21, and one end of the rotating rod 23, facing away from the first hinge seat 24, extends into the second hinge seat 26. A second hinge shaft 27 is provided on the second hinge seat 26, passing through the second hinge seat 26 and the rotating rod 23, and is fixedly connected to the second hinge seat 26, thereby hinged the handrail 22 to the walkway tread 21. The guardrail bars 222 are long, circular rods, and one end of the guardrail bars 222 is connected to the handrail 22 via a cross-shaped connector. The cross-shaped connector is a conventional technology in the prior art and will not be described in detail.

[0055] Reference Figure 2 At least one hinge seat 24 is provided, and the number of first hinge shafts 25, rotating rods 23, second hinge seats 26, and second hinge shafts 27 corresponds to the number of hinge seats 24. In this embodiment, a single walkway handrail mechanism 2 is provided with six hinge seats 24. The six hinge seats are evenly distributed along the length direction of the base 11. The number of first hinge shafts 25, rotating rods 23, second hinge seats 26, and second hinge shafts 27 corresponds to the number of hinge seats 24. The six first hinge shafts 25 pass through the six hinge seats 24 and the six rotating rods 23, making the walkway tread 21 rotate more stably on the base 11. The six second hinge shafts 27 pass through the six second hinge seats 26 and the six rotating rods 23, making the handrail 22 rotate more stably on the walkway tread 21.

[0056] Reference Figure 6 and Figure 7A hinge seat 28 is provided on the top cover plate 14. An auxiliary rod 29 is connected to one end of the guardrail 222 away from the handrail 22. The auxiliary rod 29 is detachably connected to the guardrail 222. A connecting rod 30 is hinged to the auxiliary rod 29. The connecting rod 30 is a long rod, and its two ends are respectively hinged to the auxiliary rod 29 and the hinge seat 28. Through the hinge seat 28, the auxiliary rod 29, and the connecting rod 30, the rotation range of the handrail 22 and the walkway tread 21 can be limited, making the entire rotation process more stable.

[0057] When the walkway tread 21 is opened or retracted, the hinge joint between the auxiliary rod 29 and the connecting rod 30, and the hinge joint between the connecting rod 30 and the hinge seat 28 are rotated by driving any part of the handrail 22. This causes the connecting rod 30 to rotate, simultaneously driving the rotating rod 23 to rotate along the first hinge axis 25 and the second hinge axis 27. The rotating rod 23 then drives the walkway tread 21 to rotate, thus opening or retracting the walkway tread 21. Furthermore, a handle (not shown in the figure) is provided on the guardrail frame 221. The handle is fixedly connected to the guardrail frame 221, allowing operators to easily grip it and preventing injury. In addition, the elastic element 31 further reduces effort.

[0058] Reference Figure 5 The elastic element 31 is a torsion spring, which is a very mature technology in the prior art, and will not be described in detail here. The elastic element 31 is sleeved on the first hinge shaft 25. One end of the elastic element 31 abuts against the hinge seat 24, and the other end of the elastic element 31 is wrapped around the rotating rod 23. The torsion spring can provide force in the rotation direction of the walkway tread 21. The torsion spring is suitable for hinge structures that are frequently opened and closed, can make efficient use of space, and provide a labor-saving effect.

[0059] When the walkway pedal 21 is in the retracted state, the operator holds and drives the handle, causing the hinge between the drive auxiliary rod 29 and the connecting rod 30, as well as the hinge between the connecting rod 30 and the hinge seat 28, to rotate. This causes the connecting rod 30 to rotate, simultaneously driving the rotating rod 23 to rotate along the first hinge axis 25 and the second hinge axis 27. The rotating rod 23 drives the walkway pedal 21 to rotate, and combined with the weight of the walkway pedal 21, it compresses the elastic element 31, allowing the walkway pedal 21 to be easily and quickly opened, thereby increasing the efficiency of maintenance and repair. When the walkway pedal 21 is in the open state, the operator holds and drives the handle, causing the elastic element 31 to be compressed, providing a spring force in the return direction of the walkway pedal 21, helping the walkway pedal 21 to retract, making the retraction of the walkway pedal 21 more effortless and faster.

[0060] The implementation principle of this application is as follows: by modularly disassembling the housing 1 into a base 11, end plates 12, side plates 13, and a top cover 14, it facilitates transportation, disassembly, maintenance, and cleaning / sand flushing. If any component of the base 11, side plates 13, end plates 12, or top cover 14 is damaged, only the corresponding component needs to be replaced, without replacing the entire housing 1. Modularization of the housing 1 is particularly important for equipment with high sealing requirements. In addition, the walkway railing mechanism 2 supports operators for maintenance and repair, which is conducive to the long-term stable operation of the generator set.

[0061] When the walkway pedal 21 is in the retracted state, the operator holds and drives the handle, causing the hinge between the drive auxiliary rod 29 and the connecting rod 30, as well as the hinge between the connecting rod 30 and the hinge seat 28, to rotate. This causes the connecting rod 30 to rotate, simultaneously driving the rotating rod 23 to rotate along the first hinge axis 25 and the second hinge axis 27. The rotating rod 23 drives the walkway pedal 21 to rotate, and combined with the weight of the walkway pedal 21, it compresses the elastic element 31, allowing the walkway pedal 21 to be easily and quickly opened, thereby increasing the efficiency of maintenance and repair. When the walkway pedal 21 is in the open state, the operator holds and drives the handle, causing the elastic element 31 to be compressed, providing a spring force in the return direction of the walkway pedal 21, helping the walkway pedal 21 to retract, making the retraction of the walkway pedal 21 more effortless and faster.

[0062] The walkway tread 21 is detachably connected to the walkway step 21 via the rotating rod 23, the hinge seat 24 is detachably connected to the base 11, and the auxiliary rod 29 is detachably connected to the guardrail 222. This allows the walkway step 21, handrail 22, connecting rod 30, and hinge seat 28 to form multiple splicing modules, enabling the walkway handrail mechanism 2 to be quickly assembled and disassembled, further facilitating transportation, disassembly, maintenance, and cleaning.

The diesel power mechanism is used to burn diesel fuel to generate electrical energy, and the control and operation mechanism is used to control the working state of the diesel power mechanism. The diesel power mechanism and the control and operation mechanism are electrically connected.

[0065] The implementation principle of this application is as follows: when generating electricity, the working state of the diesel power mechanism is controlled by the control operating mechanism, and the diesel power mechanism generates electrical energy by burning diesel.
