[0027] The beneficial effects of this utility model are:

[0028] 1. After the left, middle, and right protective covers are attached sequentially from left to right, the mounting grooves at the bottom of the left, middle, and right protective covers are then attached sequentially to form a complete U-shaped mounting groove. During assembly, the U-shaped protrusion at the top of the soundproof cover is inserted into the U-shaped mounting groove, and then the two are locked together with screws. The installation is simple and quick, and the protective effect is significant. Furthermore, after the left, middle, and right protective covers are attached sequentially from left to right, the outer partitions on the outside of the left, middle, and right protective covers are attached sequentially to form a complete U-shaped outer partition. After the protective device is installed, the downward-bent U-shaped outer partition is located outside the gap between the upper cover plate and the middle protective plate of the protective cover, and the bottom of the U-shaped outer partition is located at the bottom of the gap, which can prevent rainwater from seeping into the interior from the gap, thus providing a good protective effect.

The strip-shaped fixing covers enclose the two adjacent top partitions inside and are fixedly connected to the left and middle protective covers. Strip-shaped fixing covers are also provided at the top of the two adjacent top partitions on the middle and right protective covers. The strip-shaped fixing covers enclose the two adjacent top partitions inside and are fixedly connected to the middle and right protective covers. Here, the top partitions and strip-shaped fixing covers have a synergistic effect in protection and are indispensable. After the strip-shaped fixing covers are assembled, there will inevitably be a small gap between the strip-shaped fixing covers and the corresponding protective covers. The strip-shaped fixing covers can block most of the rainwater from seeping in, but a small amount of rainwater will still seep in through the gap. At this time, since there are top partitions inside, the top partitions can prevent rainwater from continuing to flow into the protective covers.

[0030] 3. Multiple intermediate protective covers are set, and they are attached sequentially from left to right. After two adjacent intermediate protective covers are attached to each other, the two adjacent top partitions on the two adjacent intermediate protective covers are also attached to each other. The top of the two adjacent top partitions on the two adjacent intermediate protective covers are provided with strip fixing covers. The strip fixing covers wrap around the two adjacent top partitions and are fixedly connected to the two adjacent intermediate protective covers. During assembly, according to the actual length of the soundproof cover, a corresponding number of intermediate protective covers are added between the left and right protective covers to meet the protection requirements of soundproof covers of different lengths. This method has a wide range of applications. Attached Figure Description

[0041] The present invention will be further described below with reference to the embodiments.

[0042] pass Figures 1-8It can be seen that the soundproof cover of the blower unit uses a top protective device, which includes a left protective cover 1, a middle protective cover 2, and a right protective cover 3, which are attached to each other from left to right.

[0043] The outer side of the left protective cover 1 is provided with a downwardly bent outer partition 8. The bottom end of the left protective cover 1, near the front, rear, and left outer sides, is provided with inner protrusions 9. A mounting groove 7 is provided between the three inner protrusions 9 and the outer partition 8. The mounting groove 7 is an annular groove with an opening on the right side. The top of the right outer partition 8 of the left protective cover 1 is provided with an upwardly protruding top partition 10. The outer side of the middle protective cover 2 is provided with a downwardly bent outer partition 8. The bottom end of the middle protective cover 2, near the front and rear outer sides, is provided with inner protrusions 9. A mounting groove 7 is provided between the two inner protrusions 9 and the front and rear outer partitions 8, respectively. The mounting groove 7 is an annular groove with openings on both the left and right sides. The middle protective cover... The top of the left and right outer partitions 8 of the 2 are respectively provided with upwardly protruding top partitions 10. The outer side of the right protective cover 3 is provided with a downwardly bent outer partition 8. The bottom of the right protective cover 3 is provided with inner protrusions 9 near the front, rear and right outer sides respectively. There is a mounting groove 7 between the three inner protrusions 9 and the outer partition 8. The mounting groove 7 is an annular groove with an opening on the left side. The top of the left outer partition 8 of the right protective cover 3 is provided with an upwardly protruding top partition 10. After the left protective cover 1, the middle protective cover 2 and the right protective cover 3 are attached from left to right, the two adjacent top partitions 10 on the left protective cover 1, the middle protective cover 2 and the right protective cover 3 are also attached in sequence.

[0044] After the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are attached from left to right, the mounting grooves 7 at the bottom of the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are attached in sequence to form a complete U-shaped mounting groove. During assembly, the U-shaped boss at the top of the soundproof cover is inserted into the U-shaped mounting groove, and then the two are locked together with screws.

[0045] After the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are attached from left to right, the outer partitions 8 on the outside of the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are attached in sequence to form a complete U-shaped outer partition. After the protective device is installed, the downward-bent U-shaped outer partition is located outside the gap between the upper cover plate and the middle protective plate of the protective cover. Furthermore, the bottom of the U-shaped outer partition is located at the bottom of the gap, which can prevent rainwater from seeping into the interior from the gap, thus providing a good protective effect.

[0046] The top ends of two adjacent top partitions 10 on the left protective cover 1 and the middle protective cover 2 are provided with strip-shaped fixing covers 4. The strip-shaped fixing covers 4 enclose the two adjacent top partitions 10 inside them. The strip-shaped fixing covers 4 are fixedly connected to the left protective cover 1 and the middle protective cover 2. The top ends of two adjacent top partitions 10 on the middle protective cover 2 and the right protective cover 3 are provided with strip-shaped fixing covers 4. The strip-shaped fixing covers 4 enclose the two adjacent top partitions 10 inside them. The strip-shaped fixing covers 4 are fixedly connected to the middle protective cover 2 and the right protective cover 3.

[0047] Here, the top partition 10 and the strip fixing cover 4 work together for protection and are indispensable. After the strip fixing cover 4 is assembled, there will inevitably be a small gap between the strip fixing cover 4 and the corresponding protective cover. The strip fixing cover 4 can block most of the rainwater from seeping in, but a small amount of rainwater will still seep in through the gap. At this time, since the top partition 10 is provided inside, the top partition 10 can prevent rainwater from continuing to flow into the protective cover.

[0048] In one specific embodiment, the bottom ends of the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are respectively fixed with reinforcing ribs 6. The reinforcing ribs 6 can increase the overall structural strength of the protective device, improve its impact resistance, and ensure its stability during application.

[0049] In one specific embodiment, the bottom end of the right outer partition 8 of the left protective cover 1 is provided with a support plate 11 bent to the right, the bottom ends of the left and right outer partitions 8 of the middle protective cover 2 are respectively provided with seat plates 12 bent inward, and the bottom end of the left outer partition 8 of the right protective cover 3 is provided with a support plate 11 bent to the right. When the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are fitted together, the seat plate 12 is first placed on the support plate 11, and then pushed in to quickly complete the alignment between adjacent protective covers. There is no need to repeatedly align the height position between adjacent protective covers. The operation is simple and quick, saving assembly time. Then, it is fixed by the strip fixing cover 4 to complete the assembly of the protective device.

[0050] In one specific embodiment, there are multiple intermediate protective covers 2, which are sequentially attached from left to right. After two adjacent intermediate protective covers 2 are attached to each other, the two adjacent top partitions 10 on the two adjacent intermediate protective covers 2 are also attached to each other. The top of the two adjacent top partitions 10 on the two adjacent intermediate protective covers 2 are provided with strip-shaped fixing covers 4, which wrap the two adjacent top partitions 10 inside. The strip-shaped fixing covers 4 are also fixedly connected to the two adjacent intermediate protective covers 2. During assembly, according to the actual length of the soundproof cover, a corresponding number of intermediate protective covers 2 are added between the left protective cover 1 and the right protective cover 3 to meet the protection requirements of soundproof covers of different lengths, thus having a wide range of applications.

[0051] In one specific embodiment, the top of the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are respectively fixed with lifting lugs 5, which can realize the hoisting and transportation of the protective device.

[0052] In one specific embodiment, the top of the left protective cover 1, the middle protective cover 2, and the right protective cover 3 are ridged in the middle, which can prevent rainwater from accumulating on the top of the protective device, and the rainwater can be quickly discharged to both sides. In addition, the ridged structure can further increase the overall robustness of the protective device.

[0053] In one specific embodiment, the outer partition plate 8 on the outside of the U-shaped mounting groove is bent downward to a height of 20mm ± 1mm, which is sufficient for the protective use of most soundproof enclosures.

[0054] The thickness of the left protective cover 1, the middle protective cover 2, the right protective cover 3, and the outer partition 8 is 1.5mm ± 0.2mm. This thickness ensures the overall structural stability of the protective device while minimizing the overall weight of the protective device, making assembly and turnover convenient, and reducing production costs.

[0055] In one specific embodiment, the strip-shaped fixing cover 4 is fixed to the left protective cover 1, the middle protective cover 2, and the right protective cover 3 by screws, which facilitates assembly and maintenance.

[0056] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
