Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically to a water curtain ventilation fan. Background Technology

[0002] Water curtain ventilation fan is a device that combines water curtain cooling and ventilation functions. It is widely used in industrial plants, agricultural greenhouses, livestock farms and other places that require cooling, dust removal and ventilation. It achieves cooling by absorbing heat through water evaporation, and at the same time uses a fan to exhaust hot air from the room to improve the environment.

[0003] The installation of the water curtain ventilation fan (such as...) Figure 3 As shown, the water curtain and fan components need to be installed separately and preferably positioned relative to each other. When installing the fan component, it is generally secured to the wall, window frame, etc. During subsequent use, long-term dust accumulation, wear, or damage will require cleaning or replacement.

[0004] The existing installation of this type of fan generally uses positioning components for positioning to facilitate cleaning and replacement after disassembly and assembly. These positioning components can use a matching structure similar to "slots and plugs". At the same time, in order to enhance stability, flexible clamping materials are usually added. At this time, since the fan is generally large and heavy, it will stick to the flexible clamping material during installation, creating significant resistance, or requiring a certain amount of lifting and insertion, which has the disadvantage of being inconvenient for disassembly and assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a water curtain ventilation fan in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a water curtain ventilation fan, including a fan body and an externally fixed mounting assembly;

[0008] The mounting assembly includes a fixed ring, a clamping pad that is fixed to the inner end of the fixed ring, a rotating ring that extends into the inner side of the fixed ring and is pressed against the clamping pad, a pressure plate that is pressed against the clamping pad, and a fastener that connects and fixes the pressure plate, the clamping pad and the fixed ring. The outer side of the rotating ring is fixed to the pressure plate, and the outer side of the fan body is fixed to the rotating ring.

[0009] The mounting components also include a guide groove at the bottom of the moving ring and universal balls fixed at the bottom of the inner ring of the fixed ring, with the outer side of the universal balls fitting and moving within the guide groove.

[0010] As a preferred technical solution of this utility model, the universal ball bearings are provided in two sets and are symmetrically arranged on the lower sides of the inner ring end of the fixed ring.

[0011] As a preferred technical solution of this utility model, the inner ring end of the fixed ring is composed of a continuous convex surface and a concave surface, and the convex surface and the concave surface are attached and fixed to the pressure pad, and the outer ring end of the moving ring is fitted with the convex surface and the concave surface when it is attached to the pressure pad.

[0012] As a preferred technical solution of this utility model, the fixing component is a bolt, which simultaneously penetrates both sides of the pressure plate and the pressure pad and is threadedly embedded in the fixing ring.

[0013] As a preferred technical solution of this utility model, it also includes several sets of handles fixed to the outside of the moving ring.

[0014] The beneficial effects of this utility model are as follows:

[0015] By setting guide grooves with left and right orientations at the bottom of the moving ring, and installing multiple sets of universal balls from left to right on the lower side of the bottom of the inner ring of the fixed ring, the moving ring is supported by the universal balls when it is placed inside the fixed ring. At this time, the weight of the moving ring and the fan body will not be completely pressed on the clamping pad or the inner ring end of the fixed ring. The rolling assistance displacement provided facilitates disassembly and assembly. Attached Figure Description

Detailed Implementation

[0020] like Figures 1-4 As shown, this utility model proposes: a water curtain ventilation fan, including a fan body 1 and an externally fixed mounting assembly 2, such as... Figures 3-4 As shown, the fan is installed on the left and the water curtain is installed on the right. The fan body 1 generates a leftward airflow to exhaust the air in the working space, thereby introducing the air on the right side of the water curtain into the working space.

[0021] The specific structure of installation component 2 is shown below:

[0022] The mounting assembly 2 includes a fixed ring 21, a clamping pad 22 that is fixed to the inner ring end of the fixed ring 21, a moving ring 23 that extends into the inner side of the fixed ring 21 and is pressed against the clamping pad 22, a pressure plate 24 that is pressed against the clamping pad 22, and a fastener 25 that connects and fixes the pressure plate 24, the clamping pad 22 and the fixed ring 21. The outer side of the moving ring 23 is fixed to the pressure plate 24, and the outer side of the fan body 1 is fixed to the moving ring 23. The clamping pad 22 is made of rubber.

[0023] The fixed ring 21 is pre-embedded in the wall. The moving ring 23 moves to the left and can be placed inside the fixed ring 21 and pressed against the pressure pad 22, providing positioning and good stability. The pressure plate 24 is moved synchronously by the moving ring 23 and contacts the pressure pad 22 to adhere to the right side of the fixed ring 21. Then, the pressure plate 24, the pressure pad 22 and the fixed ring 21 are connected and fixed using the fastener 25.

[0024] The fixing member 25 is a bolt, which passes through both sides of the pressure plate 24 and the pressure pad 22 and is threaded into the fixed ring 21. The fixing member 25 passes through the left and right sides of the pressure plate 24 and the pressure pad 22 and is partially embedded in the fixed ring 21. The fixing is achieved by the threaded connection between the fixing member 25 and the fixed ring 21 (the fixing member 25 can also be threaded to the fixed ring 21).

[0025] Furthermore, the mounting assembly 2 also includes a guide groove 26 located at the bottom of the moving ring 23 and a universal ball bearing 27 fixed to the bottom of the inner ring end of the fixed ring 21, with the outer side of the universal ball bearing 27 fitting and moving within the guide groove 26.

[0026] A guide groove 26 with the bar end facing left and right is provided at the bottom of the moving ring 23. Multiple sets of universal balls 27 are installed from left to right on the lower side of the bottom of the inner ring end of the fixed ring 21. When the moving ring 23 is placed inside the fixed ring 21, the universal balls 27 support the movement of the moving ring 23. At this time, the weight of the moving ring 23 and the fan body 1 will not be completely pressed on the pressing pad 22 or the inner ring end of the fixed ring 21. The rolling assistance displacement provided facilitates disassembly and assembly.

[0027] Two sets of universal ball bearings 27 are symmetrically arranged on the lower sides of the inner ring end of the fixed ring 21, such as... Figure 2 As shown, universal ball bearings 27 are installed at two symmetrical positions at the lower front and lower rear ends of the inner ring 21, which provides good support balance and can improve the stability when the support is displaced.

[0028] The inner ring end of the fixed ring 21 is composed of a continuous raised surface 211 and a concave surface 212. The raised surface 211 and the concave surface 212 are attached and fixed to the pressure pad 22. When the outer ring end of the moving ring 23 is attached to the pressure pad 22, it is fitted with the raised surface 211 and the concave surface 212.

[0029] like Figure 1 As shown, the inner ring end of the fixed ring 21 is provided with a convex surface 211 and a concave surface 212 with a cross-sectional shape similar to "Z" from left to right. The convex surface 211 is closer to the annular center of the fixed ring 21 than the concave surface 212. Correspondingly, the cross-sectional shape of the outer ring end of the moving ring 23 is also similar to "Z". In this way, when the moving ring 23 moves to the left, it can fit and clamp with the inner ring end of the fixed ring 21, providing good support stability.

[0030] It also includes several sets of handles 3 fixed to the outside of the moving ring 23. The handles 3 are installed on the right side of the moving ring 23 and can be used as gripping force components during disassembly and assembly, making it convenient to pull the moving ring 23 to the right and making the operation convenient.
