Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling equipment technology, and more specifically, to a ventilation and cooling device with variable air volume and variable air pressure. Background Technology
[0002] With the rapid and vigorous construction of large public buildings, large industrial buildings, especially those with tall, spacious interiors, face unique challenges. Ordinary side-wall ventilators are insufficient to ventilate and cool the core areas of the factory, failing to meet the temperature requirements of personnel. This necessitates the addition of internal ventilation equipment such as exhaust ducts and fans. This not only increases initial investment costs but also occupies upper space, particularly noticeable in buildings with overhead cranes. Therefore, solving the indoor ventilation problem of large industrial buildings has become an urgent and pressing issue. To address this, we mimicked the variable angle of a helicopter propeller, which alters the airflow and pressure beneath it. This ventilation and cooling device is installed within the industrial building's interior area. Based on temperature, airflow, and pressure sensors located within a 1.5m radius of the ground, the device's regulators are adjusted to achieve daily indoor ventilation and cooling within a 2m radius of the ground level. Furthermore, this device utilizes a permanent magnet motor, a highly efficient motor that converts electrical energy into mechanical energy using a magnetic field generated by permanent magnets. It boasts significant advantages such as simple and compact structure, energy efficiency, and low noise. Utility Model Content

The adjustable angle blades 120 are installed on the output shaft of the main reducer 150. The electric actuator 140 is installed on the adjustable angle blades. On the 120, the main fixing rod 110 is a stainless steel main fixing rod, the adjustable angle blade 120 is an aluminum alloy adjustable angle blade, the main reducer 150 is equipped with a fall protection device (the main reducer 150 is equipped with a 5mm thick steel cable as a fall protection device), the permanent magnet motor 130 is a first-class energy efficiency motor, the adjustable angle blade 120 has an adjustment angle of 5-12°, the sensor 160 includes a temperature sensor, a wind speed sensor and a wind pressure sensor, the permanent magnet motor 130, the electric actuator 140 and the main reducer 150 are electrically connected to the sensor 160 through wired or 5G wireless transmission 190; The mounting mechanism 170 is installed on the main fixing rod 110 and the roof. The mounting mechanism 170 is set up to install the main fixing rod 110 onto the roof. The mounting mechanism 170 includes a main beam 171, a top plate 172, a first bolt 173, a clamping plate 174, and a second bolt 176. The main beam 171 is fixed on the roof. The lower end of the screw of the first bolt 173 is fixed on the upper surface of the top plate 172. The clamping plate 174 is clamped on the main beam 171. The screw of the first bolt 173 passes through the main beam 171 and the clamping plate 174. The nut of the first bolt 173 is threaded on its screw. One end of the screw of the second bolt 176 is fixed on the outer wall of the main fixing rod 110. The screw of the second bolt 176 passes through the top plate 172. The nut of the second bolt 176 is threaded on its screw. The stabilizing mechanism 180 is also installed on the main fixing rod 110 and the roof. The stabilizing mechanism 180 makes the main fixing rod 110 more firmly fixed to the roof. The stabilizing mechanism 180 includes a top plate secondary fixing member 181, a steel cable 182, a ring 183, and a second connecting member 184. The top plate secondary fixing member 181 is fixed to the roof, the ring 183 is fixed to the outer wall of the main fixing rod 110, one end of the steel cable 182 is installed on the top plate secondary fixing member 181, one end of the second connecting member 184 is installed on the ring 183, and the other end of the second connecting member 184 is installed on the other end of the steel cable 182.
[0018] Specifically, the working principle of this variable air volume and variable air pressure ventilation and cooling device is as follows: During use, based on the temperature, wind speed, and air pressure measured by sensor 160, sensor 160 transmits signals to permanent magnet motor 130, electric actuator 140, and main reducer 150. The permanent magnet motor 130 and main reducer 150 drive the adjustable angle blades 120 to rotate. The electric actuator 140 adjusts the angle of the adjustable angle blades 120. According to Bernoulli's principle, the air velocity is higher and the pressure is lower on the upper surface of the adjustable angle blades 120, while the air velocity is lower and the pressure is higher on the lower surface, creating a pressure difference (wind pressure). This changes the wind pressure and air volume, reducing the temperature in the indoor working area. This achieves daily indoor ventilation and cooling within a 2m radius above ground in industrial plants, enabling variable air volume and variable air pressure operation to cool the hot and humid indoor air. The air is exhausted outdoors. Simultaneously, a permanent magnet motor 130 is used, a high-efficiency motor that converts electrical energy into mechanical energy by generating a magnetic field with permanent magnets. It boasts significant advantages such as simple and compact structure, energy efficiency, and low noise. The top plate 172 and clamping plate 174 ensure the main fixing rod 110 is more firmly fixed to the main beam 171. Several second connecting parts 184 further enhance the stability of the main fixing rod 110, ensuring the safe operation of the device and guaranteeing the safety of indoor personnel. This variable air volume and variable air pressure ventilation and cooling device can solve the ventilation and cooling problems in the core areas of large industrial buildings, especially tall, spacious industrial buildings. It avoids the need for numerous mechanical exhaust fans and central air conditioning systems on the side walls, avoiding problems such as excessive initial investment. It also solves the indoor ventilation problem during transitional seasons, achieving energy saving, low carbon emissions, and environmental protection! Meanwhile, the installation of a permanent magnet motor (Level 1 energy efficiency) effectively reduces operating costs; the addition of a fall arrestor effectively protects the safety of personnel indoors; furthermore, the device incorporates a main reducer (150) that also serves as a fall arrestor, an installation mechanism (170), a stabilizing mechanism (180), high-strength bolts, and a series of other robust measures to ensure safe operation and the safety of personnel indoors. In summary, this ventilation and cooling device fills a technological gap in the field of high-ceilinged space engineering: it achieves indoor ventilation and cooling without the need for an air conditioning system, solving the ventilation and cooling problems in high-ceilinged spaces such as industrial plants, filling a gap in this field, and bringing irreplaceable and significant benefits to social innovation, technological progress, and efficiency improvement!
