Description

Technical Field

[0001] This utility model relates to the field of air volume regulation equipment technology, and in particular to an air volume regulator applicable to high-altitude areas. Background Technology

[0002] Air volume regulators are widely used in ventilation, air conditioning, and air purification systems in industrial plants and civil buildings, as well as in cold and heat transport pipelines.

[0003] Chinese Patent: CN220750311U, title: A non-powered embedded fresh air module. This prior art discloses that the opening and closing angle of the louvered window can be adjusted by manually adjusting the lever, thereby realizing the function of air volume adjustment. However, the structural strength of this louvered window is poor and it is easily damaged by strong winds.

[0004] High-altitude areas have high wind speeds, and conventional louvered air vents are not strong enough and are easily damaged by strong winds. Therefore, it is necessary to provide an airflow regulator with high structural strength and stable air intake adjustment for use in high-altitude areas. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An airflow regulator for use in high-altitude areas includes:

[0007] The housing has arched portions at both its top and bottom ends;

[0008] A dual-roller adjustment assembly includes two adjusting rollers arranged vertically. Each adjusting roller has a cylindrical structure and a long groove with a fan-shaped cross-section. A baffle is provided inside the long groove. The two adjusting rollers are rotatably connected to the inside of the housing, and one end of each adjusting roller penetrates through the housing.

[0009] A drive assembly is connected to the outside of the housing, and the two adjusting rollers are connected through the drive assembly at one end of the housing.

[0010] Furthermore, the drive assembly includes a drive motor, a drive gear, and a driven gear. The drive motor is fixedly connected to the outer wall of the housing. The ends of the two adjusting rollers passing through the housing are respectively connected to the drive gear and the driven gear. The drive gear is connected to the power output end of the drive motor, and the driven gear is driven by the drive gear.

[0011] Furthermore, the end of the baffle away from the long groove is flush with the outer wall of the adjusting roller.

[0012] Furthermore, sealing strips are provided on the baffle and the adjusting roller.

[0013] Furthermore, one end of the adjusting roller is located inside the arched portion.

[0014] Furthermore, a sealing strip is provided inside the arched portion.

[0015] Furthermore, the fan-shaped cross-sectional angle of the long groove is 110°-120°.

[0016] Furthermore, the air inlet end of the housing is provided with a dustproof component.

[0017] The beneficial effects of this utility model are as follows:

[0018] By setting the baffles on the adjusting roller, the adjusting roller can ensure the strength of the baffles when facing strong winds. The baffles have higher circumferential strength, which is convenient for application in high-altitude areas. Furthermore, the sides of the long groove can effectively buffer high-speed winds, further ensuring the stable operation of the device. With sufficient device strength, the simultaneous movement of the two baffles can achieve stable adjustment of the air intake. Attached Figure Description

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example

[0028] Combination Figure 1-5 This embodiment provides an airflow regulator for use in high-altitude areas, including a housing 1, a dual-roller adjustment assembly 3, and a drive assembly 4. The housing 1 has arched portions 2 at both its top and bottom. The dual-roller adjustment assembly 3 includes two vertically arranged adjustment rollers 31, each with a cylindrical structure. One end of each adjustment roller 31 is located within the arched portion 2, which, by accommodating part of the adjustment roller 31, can reduce the volume of the housing 1 to a certain extent. Each adjustment roller 31 has a fan-shaped groove 311 with a baffle 312 inside. The two adjustment rollers 31 are rotatably connected to the inside of the housing 1, with one end of each roller penetrating through the housing 1. The drive assembly 4 is connected to the outside of the housing 1, and the ends of the two adjustment rollers 31 penetrating through the housing 1 are connected via the drive assembly 4.

[0029] When the two adjusting rollers 31 rotate under the drive of the drive assembly 4, the two corresponding baffles 312 can cooperate to close or open the air inlet, and the opening angle of the air inlet can be adjusted according to the rotation angle of the adjusting rollers 31, thereby adjusting the air intake volume; when the two baffles 312 are in the open air inlet state, such as Figure 5 As shown, the side of the long slot 311 can buffer the incoming air, reduce the air intake wind speed in high-altitude areas, and ensure the safe use of the fresh air system.

[0030] The drive assembly 4 includes a drive motor 41, a drive gear 42, and a driven gear 43. The drive motor 41 is fixedly connected to the outer wall of the housing 1. The two adjusting rollers 31 are respectively connected to the drive gear 42 and the driven gear 43 at their ends penetrating the housing 1. The drive gear 42 is connected to the power output end of the drive motor 41, and the driven gear 43 is connected to the drive gear 42 in a transmission connection. Under the driving action of the drive motor 41, the driven gear 43 and the drive gear 42 can rotate in opposite directions, ensuring that the baffles 312 on the two adjusting rollers 31 move away from or closer to each other at the same time, making adjustment more convenient.

[0031] The end of the baffle 312 away from the long groove 311 is flush with the outer wall of the adjusting roller 31, making the structure more compact and ensuring the sealing effect of the air inlet in the closed state.

[0032] The baffle 312 and the adjusting roller 31 are provided with sealing strips, which makes the air inlet more sealed in the closed state; the inside of the arched part 2 is provided with a sealing strip to prevent air leakage from the arched part 2 and the adjusting roller 31.

[0033] The fan-shaped cross-section angle of the long groove is 110°-120°, preferably 110°. This angle setting ensures that the baffle 312 can open to a large angle, and the side of the long groove 311 can effectively buffer the high-speed wind.

[0034] The air inlet of the housing 1 is equipped with a dustproof component to ensure that the air entering the fresh air system is clean.

[0035] This utility model sets the baffle 312 on the adjusting roller 31. The adjusting roller 31 can ensure the strength of the baffle 312 when facing strong winds. The baffle 312 has higher circumferential strength, which is convenient for application in high-altitude areas. In addition, the side of the long groove can effectively buffer high-speed winds, further ensuring the stable operation of the device. With sufficient device strength, the two baffles 312 move simultaneously to achieve stable adjustment of the air intake.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
