DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example

[0030] like Figure 1 、 2 6, including a central air duct tube 10, a plurality of air outlets 11 at the bottom of the central air duct tube 10, a plurality of wind shields 12 on the side walls of the air outlets 11, a plurality of spur gears 241 on the side of the cross bar 24 close to the movable air duct 23, the number of spur gears 241 is the same as the number of movable air ducts 23, and the spur gears 241 are meshed with the fan gears 231.

[0031] It should be noted that, in this embodiment, a microwave sensor is disposed at the air outlet 11 of the central air duct 10, and a PLC controller is used to receive control signals to control the opening and closing of the wind shield 12 of the air outlet 11, as well as the adjustment of the air outlet adjustment component 20;

[0032] When the staff passes by the air outlet 11, the microwave sensor senses the number and position of people in the area. First, the PLC controller receives the signal from the microwave sensor and sends a signal to open the wind shield 12. At the same time, the wind shield 12 opens.

[0033] like Figure 1 、 3As shown in Figures 4 and 5, an air outlet adjustment component 20 is located on the inner wall of the central air duct tube 10 and at the top of the air outlet 11; the air outlet adjustment component 20 includes a support block 21 on the inner wall of the bottom of the central air duct tube 10, two support rods 22 at one end of the support block 21 and located at the top of the air outlet 11, a plurality of movable air ducts 23 on the outer wall of the support rod 22, a cross bar 24 on one side of the movable air duct 23 and at one end of the support block 21, and a connecting rod 25 on one side of the support block 21, a fan-shaped gear 231 at the top of one side of the movable air duct 23, connecting round rods 232 on both sides of the movable air duct 23, and a slider 233 on one side of the connecting round rod 232;

[0034] The bottom of the movable air duct 23 is flattened, the slider 233 supports the outer wall of the support rod 22 and is slidably connected to the outer wall of the support rod 22. The connecting rod 25 includes a first connecting rod 251 on one side of the support block 21, a second connecting rod 252 hinged to the other end of the first connecting rod 251, and a third connecting rod 253 hinged to the other end of the second connecting rod 252; the other end of the second connecting rod 252 is hinged to the side wall of the slider 233 on one side of the movable air duct 23.

[0035] It should be noted that, in this embodiment, the PLC controller sends a working signal to the motor driving the air outlet adjustment component 20, and the motor drives the first connecting rod 251 to rotate. The first connecting rod 251 is hinged to the second connecting rod 252, and the second connecting rod 252 is hinged to the side wall of the slider 233 on one side of the movable air duct 23. When the first connecting rod 251 rotates, the movable air duct 23 is slidable on the support rod 22.

[0036] Among them, when the movable air duct 23 moves, the fan gear 231 at the top of one side of the movable air duct 23 engages with the spur gear 241, causing the angle of the movable air duct 23 to change. At the same time, multiple movable air ducts 23 are connected to each other through the third connecting rod 253, so that multiple movable air ducts 23 can simultaneously assist in supplying air to the bottom side.

[0037] like Figure 1 、 2 As shown in , 7, it includes a central air duct tube 10, multiple air outlets 11 at the bottom of the central air duct tube 10, multiple wind shields 12 on the side walls of the air outlet 11, a third connecting rod 253 is connected to the slider 233 on one side of the adjacent movable air duct 23, and multiple third connecting rods 253 are provided; the first connecting rod 251 uses one end as the axis point and is driven to rotate by a motor; the central air duct tube 10 is arranged in a closed ring, and multiple wind shields 12 are distributed in a linear array at the air outlet 11, and are driven to open and close by screws and screw blocks.

[0038] It should be noted that, in this embodiment, the support block 21 is used for auxiliary support of the multiple support rods 22, and the connecting round rod 232 is used to rotate with one end of the slider 233;

[0039] According to the bottom movement of the operator at point a, the wind direction w of the air outlet 11 is adjusted by changing the angle of the movable air duct 23, which has a targeted effect, thereby reducing the number of operators, increasing the number of air valve closures, increasing the wind pressure, and reducing the load of the air conditioning unit, thereby achieving energy saving and consumption reduction effects.

[0040] The working principle of this utility model is:

[0041] In the present invention, a microwave sensor is arranged at the air outlet 11 of the central air duct 10, and a PLC controller is used to receive control signals to control the opening and closing of the wind shield 12 of the air outlet 11, as well as the adjustment of the air outlet adjustment component 20;

[0042] When a worker passes by the air outlet 11, the microwave sensor senses the number and position of people in the area. First, the PLC controller receives the signal from the microwave sensor and sends a signal to open the wind shield 12. At the same time as the wind shield 12 opens, the PLC controller sends a working signal to the drive motor of the air outlet adjustment component 20. The drive motor drives the first connecting rod 251 to rotate. The first connecting rod 251 is hinged to the second connecting rod 252. The second connecting rod 252 is hinged to the side wall of the slider 233 on one side of the movable air duct 23. When the first connecting rod 251 rotates, the movable air duct 23 is slid on the support rod 22.

[0043] During the movement of the movable air duct 23, the fan gear 231 on the top of one side of the movable air duct 23 engages with the spur gear 241, causing the angle of the movable air duct 23 to change. At the same time, multiple movable air ducts 23 are connected to each other through the third connecting rod 253, so that multiple movable air ducts 23 can simultaneously assist in supplying air to the bottom side.

[0044] The support block 21 is used for auxiliary support of the multi-support rod 22, and the connecting round rod 232 is used to rotate with one end of the slider 233;

[0045] like Figure 7 As shown, according to the bottom movement of the operator at point a, the wind direction w of the air outlet 11 is adjusted by changing the angle of the movable air duct 23, which has a targeted effect, thereby reducing the number of operators, increasing the number of air valve closures, increasing the wind pressure, and reducing the load of the air-conditioning unit, thereby achieving energy saving and consumption reduction effects.

[0046] The above embodiments are only for illustrating the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
