Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a lightweight wind turbine housing structure. Background Technology

[0002] Chinese patent document CN215486817U discloses a fan housing structure, including a main body for mounting a fan. One end of the main body is fixed with a first cover for air intake, and the other end is fixed with a second cover for air outlet. The first cover, the main body, and the second cover are sequentially connected to form a ventilation duct. The main body contains a noise reduction mechanism, which includes a sound-absorbing pad fixed to the inner wall of the main body, with several sound-absorbing holes. The main body also contains a sterilization component for sterilizing the flowing air. The first cover contains an adjustment mechanism for regulating the fan's airflow. This structure effectively reduces noise and minimizes noise interference when the fan is operating.

[0003] However, the filter screen in the above structure is fixedly installed on the structure, making it inconvenient to remove and clean it separately when dust accumulates, and also inconvenient to clean the inside of the fan housing. Therefore, we propose a lightweight fan housing structure. Utility Model Content

At least two sets of grooves are provided on the inner wall of the mounting plate. Through grooves are provided on the front side of the mounting plate in number and position corresponding to the grooves. A set of snap-fit ​​grooves are provided in each set of grooves. A set of stop pieces are provided in each set of grooves. Two sets of second springs are fixedly installed between each set of stop pieces and the inner wall of the corresponding groove. Each set of snap-fit ​​pieces is snapped into the corresponding snap-fit ​​groove.

[0011] Preferably, the mounting plate has at least two sets of mounting holes extending through it.

[0012] Preferably, at least two sets of reinforcing ribs are fixedly installed on the outer surface of the sleeve, and each set of reinforcing ribs is fixedly connected to the rear outer surface of the mounting plate.

[0013] Preferably, sound-absorbing cotton is fixedly installed on the inner wall of the sleeve.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Please see Figure 1-7This utility model provides a technical solution: a lightweight fan housing structure, including a mounting plate 1, a snap-fit ​​mechanism 8, and a limiting mechanism 7. A sleeve 2 is fixedly installed on the rear outer surface of the mounting plate 1. A trapezoidal groove 3 is opened on the rear side of the sleeve 2, and a filter screen 4 is fitted inside the trapezoidal groove 3. A protective railing 5 is fitted to the inner wall of the mounting plate 1. At least two sets of snap-fit ​​pieces 6 are fixedly installed on the outer surface of the protective railing 5. The snap-fit ​​mechanism 8 is disposed on the mounting plate 1 and is used to snap the protective railing 5 for installation. At least two sets of snap-fit ​​pieces 6 are opened through the mounting plate 1. At least two sets of reinforcing ribs 10 are fixedly installed on the outer surface of the sleeve 2, and each set of reinforcing ribs 10 is fixedly connected to the rear outer surface of the mounting plate 1. Sound-absorbing cotton 11 is fixedly installed on the inner wall of the sleeve 2. At least two sets of finger grooves 12 are opened on the rear side of the filter screen 4. Through the mounting plate 1, sleeve 2 and reinforcing ribs 10, the overall structural stability is ensured while reducing the overall wall thickness, and the structure is made lightweight. At the same time, the noise of the fan during use can be reduced under the action of the sound-absorbing cotton 11, ensuring the structural performance and facilitating the promotion and use of the structure.

[0029] The limiting mechanism 7 is located on the rear side of the sleeve 2. The limiting mechanism 7 includes a housing 71, a limiting block 72, a connecting rod 73, and a handle 74. At least two sets of housings 71 are fixedly installed on the rear outer surface of the sleeve 2. Each set of housings 71 has a set of limiting blocks 72 that are movably installed inside. Each set of limiting blocks 72 abuts against the rear outer surface of the filter screen 4. Each set of limiting blocks 72 has a set of connecting rods 73 that are fixedly installed on it. One end of each set of connecting rods 73 passes through the housing 71 and is fixedly installed with a handle 74.

[0030] The limiting mechanism 7 also includes a first spring 75. Each set of connecting rods 73 is fitted with a set of first springs 75. The other end of each set of first springs 75 is fixedly connected to the corresponding handle 74. The other end of each set of first springs 75 is fixedly connected to the corresponding housing 71.

[0031] The snap-fit ​​mechanism 8 includes a groove 81, a through groove 82, a snap-fit ​​groove 83, a stop piece 84, and a second spring 85. At least two sets of grooves 81 are provided on the inner wall of the mounting plate 1. Through grooves 82, corresponding in number and position to the grooves 81, are provided on the front side of the mounting plate 1.

Two sets of second springs 85 are fixedly installed between each set of stop pieces 84 and the inner wall of the corresponding groove 81. Each set of snap-fit ​​pieces 6 is snapped into the corresponding snap-fit ​​groove 83. Through the limiting mechanism 7 and the snap-fit ​​mechanism 8, when dust or oil adheres to the filter screen 4 and guardrail 5 during long-term use, they can be disassembled for thorough cleaning. This also facilitates cleaning the inside of the sleeve 2. This solves the problem in some existing structures where the filter screen is fixed to the structure, making it inconvenient to remove and clean it separately when dust accumulates, and also makes it inconvenient to clean the inside of the fan casing, thus improving the practicality of the structure.

[0032] Working principle: When the filter screen 4 and the guardrail 5 need to be removed, pull each handle 74 to drive each limiting block 72 to retract into each housing 71 through each connecting rod 73. Each first spring 75 is stretched until each limiting block 72 no longer presses against the filter screen 4, and the filter screen 4 can be pried out through the finger groove 12. Then, squeeze the guardrail 5 to make each snap-fit ​​piece 6 spring against the abutment piece 84 and rotate, so that each snap-fit ​​piece 6 disengages from each through groove 82, thereby removing the guardrail 5.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
