Description

Technical Field

[0001] This utility model relates to the field of industrial fans, specifically to a mobile water curtain fan. Background Technology

[0002] Industrial fans are large-scale mechanical devices specifically designed to meet the needs of large-area, high-intensity ventilation. Their core function is to improve ambient air quality, regulate temperature, and promote airflow through powerful air circulation. They are widely used in open spaces such as factory workshops, warehouses, logistics centers, stadiums, and farms. These fans typically use large blades several meters in diameter, driven by high-power motors, to produce a three-dimensional airflow effect covering thousands of square meters. The airflow is evenly distributed and naturally gentle, effectively reducing indoor temperature while avoiding the discomfort caused by the direct blowing of traditional small fans.

[0003] Evaporative cooling fans are a type of industrial fan. They mainly consist of an evaporative cooling pad and a fan system. Water is pumped from a pool and transported to the evaporative cooling pad via a supply pipeline. The evaporative cooling pad absorbs the moisture. When air passes through the evaporative cooling pad, the water evaporates under adiabatic conditions, carrying away a large amount of latent heat, thus achieving a cooling effect. However, existing evaporative cooling fans are mainly installed on factory walls or windows, resulting in fixed locations, poor flexibility, and long water channels that are prone to leaks and difficult maintenance.

[0040] Please refer to Figure 1-10As shown, this embodiment provides a mobile water curtain fan, including a water tank base 1, a fan unit 2, a water curtain assembly 3, and a pulley assembly 4. The pulley assembly 4 is disposed on the bottom surface of the water tank base 1. Please refer to... Figure 10 As shown, the fan unit 2 and the water curtain assembly 3 are fixed on the water tank base 1, with the water curtain assembly 3 located on the air inlet side of the fan unit 2. The water tank base 1 contains a water pumping assembly 11, whose outlet end is connected to a water outlet pipe 12. The water outlet pipe 12 passes through the water tank base 1 and extends to the top of the water curtain assembly 3, with an outlet 17 on it. In this embodiment, the water pumping assembly 11 is a water pump.

[0041] The fan unit 2 and the water curtain assembly 3 are mounted on the water tank base 1. The pulley assembly 4 at the bottom of the water tank base 1 effectively improves the overall flexibility of the water curtain 32 fan and avoids installing the water curtain 32 fan on the wall. At the same time, it effectively shortens the distance between the water curtain assembly 3 and the water source. The water outlet pipe 12 is located inside the water tank and inside the water curtain 32 to add water to the water curtain 32, avoiding exposed water pipes and water leakage. Furthermore, the water tank base 1, the fan unit 2, and the water curtain assembly 3 are independent units, which facilitates classified maintenance during the inspection process and reduces maintenance costs.

[0042] Please refer to Figure 2-4 As shown, specifically, the water curtain assembly 3 includes a mounting frame 31 and a water curtain 32. The mounting frame 31 includes a side frame 311 and a top frame 312 arranged opposite to each other. The water curtain 32 is embedded in the side frame 311 and the top frame. The side frame 311 and the top frame 312 limit the water curtain 32 on both sides and the top of the water curtain 32 in the thickness direction, thereby improving the stability of the water curtain 32. At the same time, the water curtain 32 covers one side of the air inlet of the fan unit 2, ensuring that the airflow can only enter the fan unit 2 after passing through the water curtain 32, so as to fully cool the airflow. Furthermore, the top of the water curtain 32 is spaced apart from the inner top surface of the top frame 312 to form a water outlet space 33. The water outlet pipe 12 includes a water inlet section 121 and a water outlet section 122. One end of the water inlet section 121 is connected to the water outlet end of the pumping assembly 11, and the other end of the water inlet section 121 passes through the water tank seat 1 and the water curtain 32 into the water outlet space 33, and is connected to a section of the water outlet section 122. The water outlet section 122 is located within the water outlet space 33, and the water outlet 17 is located at the bottom of the water outlet section 122. The water outlet section 122 is spaced apart from the top of the water curtain 32. The water outlet space 33 provides space for the water flowing from the water outlet section 122, ensuring that the water flows evenly onto the top surface of the water curtain 32, allowing for sufficient water absorption throughout the water curtain 32 and improving its cooling effect. In this embodiment, the water outlet section 122 extends from one side of the water curtain 32 to the other side, fully utilizing the water outlet space 33 to completely cover the top of the water curtain 32, further ensuring sufficient water absorption throughout the water curtain 32.

[0043] Furthermore, the inner top surface of the top frame 312 is provided with opposing limiting plates 3121, and the water outlet section 122 is located between the limiting plates 3121. The limiting plates 3121 are located on both sides of the water outlet section 122, providing assembly space for limiting components and limiting the water outlet section 122, such as by installing limiting clamps or other limiting structures.

[0044] In this embodiment, the side of the top frame 312 extends downward to the outside of the water curtain 32, thus fully covering the water outlet space 33 and blocking water droplets splashed after the water flow collides with the water curtain 32, preventing water from splashing outside the water curtain 32 and affecting the utilization rate of the water source. Furthermore, a return port (not shown in the attached figure) is provided on the water tank base 1, located below the water curtain 32. The mounting frame 31 does not have a bottom frame, making way for the bottom of the water curtain 32. After the water flows out from the outlet section 122, it enters the water curtain 32. The water that is not absorbed or blown out flows from the top of the water curtain 32 to the bottom of the water curtain 32 and returns to the water tank base 1 through the return port, forming a water circulation, which further improves the utilization rate of the water source and reduces the operating cost.

[0045] Please refer to Figure 1 , Figure 2 and Figure 6 As shown, in this embodiment, the top surface of the water tank base 1 is provided with a front mounting position 13 and a rear mounting position 14; the fan unit 2 includes a housing 21 and a fan assembly 22 fixed inside the housing 21, and the housing 21 is fixed on the front mounting position 13. The rear end of the housing 21 is provided with an outwardly extending eave 213, which extends to the rear mounting position 14 and connects with the side wall of the rear mounting position 14. The eave 213 and the housing 21 form an "L"-shaped contact structure, with the eave 213 abutting against the rear mounting position 14, and the rear mounting position 14 applying a rearward supporting force to the eave 213, effectively improving the installation stability of the fan unit 2. The front end face of the water curtain assembly 3 is attached to the eave 213, and the water curtain assembly 3 is fixed on the rear mounting position 14.

[0046] Furthermore, a mounting groove 141 is provided on the rear mounting position 14, and the protrusion 213 extends into the mounting groove 141 and abuts against the side wall of the mounting groove 141; the bottom end of the water curtain assembly 3 is embedded in the mounting groove 141. The side wall of the mounting groove 141 abuts against the bottom side of the water curtain assembly 3 and the bottom side of the protrusion 213, providing circumferential limiting force for the rear end of the water curtain assembly 3 and the housing, thereby improving the installation stability of the fan unit 2 and the water curtain assembly 3.

[0047] Specifically, the outer casing 21 includes a circular air outlet 211 and a rectangular air inlet 212 connected to each other. The rectangular air inlet effectively increases the size of the air inlet of the fan unit 2, increasing the air volume. The circular air outlet 211 is located on the air outlet side of the fan unit 2, guiding the airflow. At the same time, the opening diameter of the circular air outlet is smaller than the opening diameter of the rectangular air inlet 212, effectively increasing the airflow velocity and improving the cooling effect. A side mounting position 15 is also provided on the top surface of the water tank base 1. The side mounting position 15 is located on the side of the circular air outlet 211, and a water inlet 16 is provided on the side mounting position 15. The water inlet 16 is set in the gap between the side of the circular air outlet 211 and the top surface of the water tank base 1, effectively increasing the operating space of the water filling structure, improving the convenience of water filling, and making full use of the top surface of the water tank base 1. Meanwhile, the water inlet 16 is located on the top surface of the water tank base 1, and the water outlet 17 is located at the bottom of the water tank base 1, so that the internal space of the water tank base 1 can store water. Compared with the side-mounted water inlet 16, this effectively increases the water storage capacity. At the same time, the water outlet 17 is located on the bottom surface of the water tank base 1, ensuring that the water in the water tank base 1 can be completely drained during the water replacement process, improving the convenience of water replacement. In this embodiment, the side of the rectangular air inlet 212 is provided with an adjustable air inlet 214. The adjustable air inlet 214 is located on the side of the air inlet of the fan unit 2, forming a three-sided air intake, increasing the air intake volume of the fan unit 2. At the same time, the air intake volume can be flexibly adjusted by adjusting the air inlet 214, improving the practicality of the water curtain 32 fan.

[0048] Please refer to Figure 3As shown, in this embodiment, the fan assembly 22 includes a mounting bracket 221, a motor 222, and a fan blade 223. The end of the mounting bracket 221 is fixedly connected to the inner side of the rectangular air inlet 212. The motor 222 is fixed on the mounting bracket 221 and passes through the mounting bracket 221 to drive the fan blade 223. A first mounting hole is provided at the end of the mounting bracket 221, and a first connector (not shown in the figure) is provided on the first mounting hole. The first connector passes through the mounting bracket 221 and is fixedly connected to the rectangular air inlet 212. In this embodiment, the first connector is a bolt. Furthermore, the inner side of the rectangular air inlet 212 is provided with relatively spaced bonding plates 215. The end of the mounting bracket 221 is embedded between the bonding plates 215 and is bonded to each other with the bonding plates 215. A second mounting hole is provided on the bonding plate 215, and a second connector (not shown in the attached drawings) is provided on the second mounting hole. The second connector passes through one bonding plate 215 and the mounting bracket 221 and is fixedly connected to the other bonding plate 215; in this embodiment, the second connector is also a bolt.
