Technical Field

[0001] This utility model relates to the field of industrial ceiling fan technology, specifically a movable industrial ceiling fan. Background Technology

[0002] Ceiling fans are typically fixed to the ceiling or mounted on beams in factory roofs, blowing air downwards to cool the area and providing relief from the heat. They are characterized by high airflow and wide coverage. Industrial ceiling fans are usually fixed to the ceilings of industrial plants to lower the temperature inside, and are particularly suitable for workshops with high ambient temperatures and high labor intensity. With the rapid development of industrial modernization, large industrial plants are constantly emerging. In the hot summer, the high temperature inside these plants seriously affects the normal work of employees. Industrial ceiling fans, as ventilation equipment for indoor circulating ventilation, have emerged and are widely used in industry.

[0003] Because the factory buildings are quite large, the existing ceiling fans cannot be moved and can only cool and ventilate certain areas of the factory. Therefore, a large number of ceiling fans need to be installed in the factory to cool and ventilate, which increases production costs. At the same time, the power transmission cables are difficult to handle.

[0004] Therefore, it is particularly important to design a movable industrial ceiling fan to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A movable industrial ceiling fan includes a support block 1. Screw nuts 101 are symmetrically arranged on both sides of the support block 1, connecting to a screw 102. A protective box 103 is provided outside the screw 102. A ceiling fan body 104 is located inside the support block 1. A cable 105 is mounted on the ceiling fan body 104, and several limiting blocks 106 are mounted on the cable 105. A connecting shaft 107 is located at the top of each limiting block 106. Rollers 108 are symmetrically arranged at both ends of the connecting shaft 107, and connecting boxes 109 are provided outside the rollers 108. A motor drives the screw 102 to rotate. The screw 102 and the screw nuts 101 on both sides of the support block 1 are tightly engaged to form a screw drive mechanism. When the motor starts, the rotational motion of the screw 102 is converted into the linear motion of the screw nuts 101, thereby driving the entire support block 1. The ceiling fan body 104 inside the fan moves back and forth. The ceiling fan body 104 is composed of a drive motor, fan blades and fan blade support. It obtains power through a cable 105 connected to a socket to ensure that the ceiling fan body 104 can operate normally. During the movement of the ceiling fan body 104, the cable 105 passes through the clearance hole inside the limit block 106 and is fixed in position by a fastening clamp to prevent the cable from shaking and falling off during the movement of the ceiling fan. At the same time, rollers 108 are symmetrically provided at both ends of the connecting shaft 107 at the top of the limit block 106. The rollers 108 roll in the slide groove inside the connecting box 109, making the movement of the ceiling fan body 104 more stable and smooth. As the screw nut 101 moves, the rollers 108 roll along the length of the slide groove, which facilitates the extension and retraction of the cable 105 to cooperate with the movement of the ceiling fan body 104.

[0025] One end of the lead screw 102 is equipped with a motor, and the output end of the motor is connected to the lead screw 102 via a coupling. The other end of the lead screw 102 is connected to the protective box 103 via a bearing seat. The rotation of the lead screw 102 drives the position movement of the ceiling fan body 102, enabling it to reciprocate. The ceiling fan body 104 includes a drive motor, fan blades, and a fan blade support. One end of the cable 105 is connected to the drive motor, and the other end of the cable 105 is connected to a socket to provide power and ensure the normal operation of the ceiling fan body 104. The limit block 106 has a clearance hole inside, through which the cable 105 passes. The cable 105 is fixed to the clearance hole by a fastening clamp to prevent the cable from shaking or falling off during the movement of the ceiling fan. The two ends of the connecting shaft 107 are connected to the roller 108 via bearing seats. The connecting box 109 has a sliding groove inside, and the roller 108 can roll along the length of the sliding groove, allowing the roller 108 to slide along the sliding groove as the lead screw nut 101 moves.

[0026] The working process of this utility model is as follows: When using this type of movable industrial ceiling fan, the motor first drives the lead screw 102 to rotate. The lead screw 102 is tightly engaged with the lead screw nuts 101 on both sides of the support block 1 to form a lead screw transmission mechanism. When the motor starts, the rotational motion of the lead screw 102 is converted into the linear motion of the lead screw nuts 101, thereby driving the entire support block 1 and the internal ceiling fan body 104 to reciprocate. The ceiling fan body 104 consists of a drive motor, fan blades, and fan blade brackets. It obtains power through a cable 105 connected to a socket to ensure that the ceiling fan body 104 can operate normally. During the movement of the ceiling fan body 104, the cable 105 passes through the clearance hole inside the limiting block 106 and is fixed in position by the fastening clamp to prevent the cable from shaking and falling off during the movement of the ceiling fan. At the same time, rollers 108 are symmetrically provided at both ends of the connecting shaft 107 at the top of the limiting block 106. The rollers 108 roll in the sliding groove inside the connecting box 109, making the movement of the ceiling fan body 104 more stable and smooth. As the lead screw nut 101 moves, the rollers 108 roll along the length of the sliding groove, which facilitates the extension and retraction of the cable 105 to coordinate with the movement of the ceiling fan body 104.
