Description

Technical Field

[0001] This utility model relates to the housing of a generator, specifically a housing for a closed generator. Background Technology

[0002] A hermetically sealed generator is a generator set that uses a sealed casing to enclose the various components of the generator (such as the generator unit, engine unit, control system unit, etc.), thereby reducing noise and interference with the surrounding environment.

[0003] Chinese patent document CN213711183U discloses a residential and commercial silent gas generator set, including a housing. The housing includes a chassis and a front panel, a rear panel, a left panel, and a right panel surrounding the outer edge of the chassis. The top is closed by a cover plate. A vertically extending column is fixed at each of the four corners of the chassis to connect the lateral edges of adjacent panels. The cover plate is hinged to one of the front panel, rear panel, left panel, and right panel so that it can be opened manually. The outer surfaces of the front panel, rear panel, and cover plate are all designed with arc-shaped curved surfaces. Correspondingly, each column is also designed with an arc shape, that is, the cross section of the column is an outwardly convex arc structure. This makes the overall appearance of the housing fuller and rounder when the housing is enclosed, and also helps to increase the internal space of the housing, which facilitates the layout of internal working components such as the generator, making the overall structure of the generator set more compact and convenient for miniaturization design.

[0004] In the prior art, the generator set's housing panel and column require fasteners such as bolts for connection. When maintaining the generator set, specialized tools for removing bolts are needed for disassembly and installation, which affects maintenance efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a casing for a closed generator to solve the problem of inconvenient maintenance of closed generators in the prior art.

[0006] To achieve the above objectives, the basic solution of this utility model provides a housing for a closed generator, including a base, a top cover, and a side plate assembly. The bottom of the side plate assembly is connected to the base, and the top cover is connected to the top of the side plate assembly. The side plate assembly includes a support unit and a maintenance door unit, which are distributed along the edge of the base. The support unit is located at a corner of the housing and is connected to the base. The maintenance door unit is pin-connected to the support unit.

[0007] The beneficial effects of this basic scheme are as follows: by connecting the maintenance door unit to the support unit via pins, the disassembly and assembly of the maintenance door unit can be carried out without the aid of professional tools. Furthermore, the support unit is located at the corner of the outer casing, allowing maintenance operations on the components of the enclosed generator to be performed immediately after the maintenance door unit is disassembled. This reduces the impact of the support unit on the maintenance operation, thereby reducing the impact of the disassembly and assembly of the outer casing on the maintenance operation of the enclosed generator, making the maintenance operation of the enclosed generator more convenient and efficient.

[0008] Preferably, the upper part of the maintenance door unit is pin-connected to the support unit, and the lower part of the maintenance door unit is pin-connected to the base. This arrangement disperses the constraints on the maintenance door unit, which helps improve the stability of the maintenance door unit under stress, and thus helps improve the structural stability of the entire shell.

[0009] Preferably, the maintenance door unit includes a front maintenance door located at the front end of the housing. The upper part of the front maintenance door is connected to the support unit pin via a first positioning pin, and the lower part of the front maintenance door is connected to the base pin via a second positioning pin. This arrangement ensures that the upper part of the front maintenance door is constrained at its two side edges, while the lower part is constrained at its bottom. This disperses the constraints on the entire front maintenance door, improving its stability under stress and consequently enhancing the overall structural stability of the housing.

[0010] Preferably, the first positioning pin is slidably connected to the front maintenance door, and the first positioning hole for engaging with the first positioning pin is provided on the side end face of the support unit facing the front maintenance door. With this arrangement, during assembly, the front maintenance door and the support unit are positioned and connected by sliding the first positioning pin into the first positioning hole, thereby preventing the front maintenance door from moving relative to the support unit in the vertical direction. This helps improve the stability of the front maintenance door when the top cover of the outer casing is opened, and reduces the occurrence of misoperation.

[0011] Preferably, the second positioning pin is connected to the lower end of the front maintenance door, and the second positioning hole for engaging with the second positioning pin is provided on the upper surface of the base. With this arrangement, when installing the front maintenance door, the lower end of the front maintenance door is constrained and fixed by vertically inserting the second positioning pin into the second positioning hole, which helps to improve the ease of installation of the front maintenance door.

[0012] Preferably, the inner side of the support unit is connected to a limiting plate for fitting against the inner side of the front maintenance door. With this arrangement, when the front maintenance door is installed, the limiting plate fits against the inner side of the front maintenance door, thereby limiting and supporting the front maintenance door, improving its ability to resist external forces acting towards the interior of the housing, and thus enhancing the protective performance of the housing.

[0013] Preferably, a locking assembly is connected between the upper part of the front maintenance door and the top cover, and the end of the top cover away from the front maintenance door is hinged to the side panel assembly. With this configuration, the top cover can be opened and closed by rotating around the hinge point, and when the top cover is in the closed state, it is connected to the front maintenance door through the locking assembly, thus preventing the top cover from opening by itself. This facilitates the fixation of the top cover when it is closed and helps to improve the stability of the outer casing.

[0014] Preferably, the maintenance door unit further includes side maintenance doors located at the left and right ends of the housing. The upper part of the side maintenance door is connected to the support unit via a third positioning pin, and the lower part of the side maintenance door is connected to the base via a fourth positioning pin. This arrangement facilitates maintenance operations on the left and right ends of the generator through the side maintenance doors. Furthermore, the upper part of the side maintenance door is constrained by the support unit, and the lower part is constrained by the base, providing three-dimensional constraint and improving the stability of the side maintenance door.

[0015] Preferably, the third positioning pin is fixed to the end of the side maintenance door, and the end of the support unit is provided with a third positioning hole that mates with the third positioning pin. The third positioning hole extends vertically through the top of the support unit. With this configuration, when installing the side maintenance door, the side maintenance door drives the third positioning pin to move vertically and engage with the third positioning hole. This achieves limiting support of the upper part of the side maintenance door by the support unit, making the side maintenance door detachable only by moving it upwards. This improves the ease of installation and disassembly of the side maintenance door.

[0016] Preferably, the fourth positioning pin is connected to the lower end of the side maintenance door, and the fourth positioning hole for cooperating with the fourth positioning pin is provided on the upper surface of the base. With this arrangement, when installing the side maintenance door, the side maintenance door drives the fourth positioning pin to be inserted vertically into the fourth positioning hole, thereby constraining the lower end of the side maintenance door by the base, which helps to improve the ease of installation and removal of the side maintenance door.

[0017] This utility model has the following beneficial effects: Compared with existing technologies, this solution uses pin connections between the maintenance door unit and the support unit and the base, respectively. This eliminates the need for specialized tools when disassembling and assembling the maintenance door unit. Consequently, the impact of disassembling and assembling the casing on the overall maintenance of the enclosed generator is minimized, thus improving the ease of maintenance for the enclosed generator.

[0019] As those skilled in the art will know, in this solution, "inner side of the support unit" refers to the side of the support unit facing the internal cavity of the outer shell. In this solution, "inner side of the front maintenance door" refers to the side of the front maintenance door facing the internal cavity of the outer shell.

[0020] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: top cover 1, support unit 2, maintenance door unit 3, front maintenance door 31, side maintenance door 32, latch hook 4, base 5, fourth positioning pin 6, first positioning hole 7, second positioning hole 8, fourth positioning hole 9, limit plate 10, first positioning pin 11, second positioning pin 12, third positioning hole 13, and third positioning pin 14.

[0021] The basic implementation examples are as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows the casing of a closed generator, with the overall shape of the casing being a cuboid. The casing includes a base 5, a top cover 1, and side panel assemblies. The bottom of the side panel assemblies is connected to the base 5, and the top cover 1 is connected to the top of the side panel assemblies. The side panel assemblies include support units 2 and maintenance door units 3, which are distributed along the edge of the base 5. The support units 2 are located at the corners of the casing and are connected to the base 5. The upper part of the maintenance door unit 3 is pin-connected to the support unit 2, and the lower part of the maintenance door unit 3 is pin-connected to the base 5.

[0022] The maintenance door unit 3 includes a front maintenance door 31 located at the front end of the housing. The front end of the housing generally refers to the end with a larger vertical surface area, which facilitates operation of most components of the enclosed generator by the operator. The upper part of the front maintenance door 31 is pin-connected to the support unit 2 via a first positioning pin 11, and the lower part of the front maintenance door 31 is pin-connected to the base 5 via a second positioning pin 12.

[0023] The first positioning pin 11 is slidably connected to the front maintenance door 31. The first positioning hole 7, which cooperates with the first positioning pin 11, is provided on the side end face of the support unit 2 facing the front maintenance door 31, so that when the front maintenance door 31 is connected to the support unit 2, the first positioning hole 7 is exactly facing the side of the front maintenance door 31. By sliding the first positioning pin 11 axially and inserting it into the first positioning hole 7, the support unit 2 supports and fixes the front maintenance door 31, realizing the connection between the front maintenance door 31 and the support unit 2. When it is necessary to disassemble the front maintenance door 31, the first positioning pin 11 is removed from the first positioning hole 7, thereby losing the mutual connection between the front maintenance door 31 and the support unit 2, and the disassembly operation of the front maintenance door 31 is realized.

[0024] The second positioning pin 12 is connected to the lower end of the front maintenance door 31, and the second positioning hole 8 for engaging with the second positioning pin 12 is provided on the upper surface of the base 5. When assembling the front maintenance door 31, the front maintenance door 31 moves vertically, causing the second positioning pin 12 to be inserted into the second positioning hole 8, thereby achieving the support and fixation of the front maintenance door 31 by the base 5. When disassembling the front maintenance door 31, it is only necessary to move the front maintenance door 31 vertically, causing the front maintenance door 31 to move the second positioning pin 12 out of the second positioning hole 8, thus achieving the separation operation of the front maintenance door 31 from the base 5.

[0025] The inner side of the support unit 2 is connected to a limiting plate 10 for fitting against the inner side of the front maintenance door 31. When assembling the front maintenance door 31, by fitting the inner side of the front maintenance door 31 against the limiting plate 10, the installation position of the front maintenance door 31 can be quickly and accurately positioned. At the same time, the limiting part can also support the edge of the front maintenance door 31, improving the stability of the front maintenance door 31.

[0026] A latching assembly connects the upper part of the front maintenance door 31 to the top cover 1. The end of the top cover 1 furthest from the front maintenance door 31 is hinged to the side panel assembly. By rotating the top cover 1 around the hinge point, the top cover 1 flips over and closes onto the top of the side panel assembly. When the top cover 1 is in the closed state, the latching assembly connects the front maintenance door 31 to the top cover 1, thus fixing the top cover 1 and preventing it from flipping freely. By unlocking the latching assembly, the top cover 1 loses the fixing effect of the front maintenance door 31, allowing the top cover 1 to flip around the hinge point, forming an opening at the top of the housing, facilitating operation by the operator on top of the generator. In this embodiment, the latching assembly includes a latch hook 4 hinged to the front maintenance door 31, and a lock hole on the top cover 1 that engages with the latch hook 4. When the top cover 1 is in the closed state, rotating the latch hook 4 allows the latch hook 4 to separate or engage with the lock hole, thus switching between locked and unlocked states.

[0027] The maintenance door unit 3 also includes side maintenance doors 32 located at the left and right ends of the outer casing. The upper part of the side maintenance door 32 is pin-connected to the support unit 2 via a third positioning pin 14, and the lower part of the side maintenance door 32 is pin-connected to the base 5 via a fourth positioning pin 6. Specifically, the third positioning pin 14 is fixedly connected to the end of the side maintenance door 32, and the end of the support unit 2 is provided with a third positioning hole 13 that cooperates with the third positioning pin 14. The third positioning hole 13 extends vertically through the top of the support unit 2. When assembling the side maintenance door 32, the side maintenance door 32 moves vertically and drives the third positioning pin 14 to engage in the third positioning hole 13, thereby achieving the support and fixation of the side maintenance door 32 by the support unit 2. When disassembling the side maintenance door 32, it is only necessary to move the side maintenance door 32 vertically upward, causing the side maintenance door 32 to drive the third positioning pin 14 out of the third positioning hole 13, thereby removing the support and fixation function of the support unit 2 and realizing the disassembly operation. Ventilation holes are provided on the side maintenance door 32 to facilitate the intake and exhaust of air from the generator.

[0028] The fourth positioning pin 6 is connected to the lower end of the side maintenance door 32, and the fourth positioning hole 9, which mates with the fourth positioning pin 6, is provided on the upper surface of the base 5. When assembling the side maintenance door 32, the side maintenance door 32 moves vertically, causing the fourth positioning pin 6 to insert into the fourth positioning hole 9, thereby supporting and fixing the bottom of the side maintenance door 32 with the base 5. When disassembling the side maintenance door 32, the side maintenance door 32 is moved vertically upwards, causing the fourth positioning pin 6 to move out of the fourth positioning hole 9, thus achieving the disassembly operation.

[0029] By adopting this solution, the maintenance door unit 3 is connected to the support unit 2 and the base 5 by pins, so that the disassembly and assembly of the maintenance door unit 3 does not require the use of special tools. This reduces the impact of the disassembly and assembly of the outer casing on the overall maintenance of the enclosed generator, thereby improving the convenience of maintenance of the enclosed generator.

[0030] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
