Description

{Blowing device for horizontal direction revolution}

The present invention relates to a blower used for ventilation. In particular, it is installed in closed spaces such as underground parking lots and tall buildings such as auditoriums, gymnasiums, lobbies, and factories to blow air in a horizontal rotation manner to blow air over a wide area. It relates to a horizontal rotary blower that allows ventilation to be carried out quickly and the blowing volume can be increased when necessary.

In general, blowers are used to improve indoor air quality by supplying outdoor air indoors. In this way, the blower is used to forcibly induce air flow to replace indoor air with external air or to remove gases such as toxic gases in a specific area.

For example, underground parking lots, auditoriums, gymnasiums, lobbies, factories, etc. are characterized by high airtightness and poor exchange between outside and inside air. For this reason, if smoke cannot be controlled or toxic gases cannot be discharged in the event of a fire, serious casualties are bound to occur. It will also have a negative impact on the rescue and suppression activities of the fire brigade. In particular, in the case of underground parking lots in Korea, there are only regulations on fire extinguishing equipment and alarm equipment, but there are no special regulations on smoke control or smoke, so the risk is greater when the initial fire suppression fails.

General ventilation equipment supplies air through a blower, guides pollutants to the exhaust port through a manned fan, and discharges polluted air through an exhaust fan. Therefore, even in the event of a fire, the blower only provides air supply, so the ability to quickly discharge toxic gas cannot be expected, increasing the risk of suffocation.

As ventilation equipment is intended to bring in outside air and discharge automobile exhaust gases or pollutants, a blowing device that can quickly discharge toxic gases that cause casualties in the event of a fire is required.

As the technology behind the present invention, a 'blower device' is proposed in Korean Patent Publication No. 10-2022-0003880 (Patent Document 1). This includes dual inverted blades to minimize swirl flow, thereby minimizing the reduction in air volume due to the purification filter, and maintaining a stable torque. However, this background technology cannot be used for both supply and exhaust because blowing occurs in only one direction. Therefore, when a blower is installed for air supply, there is a problem in that toxic gases indoors cannot be quickly discharged to the outside in the event of a fire.

<First embodiment>

The blower 10 according to the first embodiment of the present invention allows the blower casing 121 to rotate around the vertical rotation axis 210 as shown in FIGS. 1 to 5, thereby blowing the air generated from the blower motor 123. The direction is horizontal, left and right.

As shown in FIGS. 6 and 7, the blowing casing 121 has an inlet port 121a at one end and an outlet port 121b at the other end. A blower motor 123 is installed inside the blower casing 121. The blower motor 123 is supported and fixedly installed on the central axis of the blower casing 121. As shown in Figures 8 and 9, the blower motor 123 is attached to a wing hub 124 fitted to its rotation axis, a wing support 125 arranged in a circle around the wing hub 124, and a wing support 125, respectively. It is provided with a connected plate-shaped axial flow wing (126). The axial flow blades 126 have an inclined structure with the same offset angle (θ) with respect to the rotation axis center line (X) of the blower motor 123. Therefore, when the blower motor 123 rotates forward and backward, the same discharge air volume is generated by the axial flow blade 126. Therefore, the blower 10 can supply air in normal times (when there is no fire), and in particular, can rotate in reverse in the event of a fire to quickly exhaust air with the same amount of air. The blower motor 123 can be remotely controlled with a remote control not shown.

A vertical rotation shaft 210 is installed in the central upper part of the discharge flow rate control casing 131, which is coaxially inserted and fixedly arranged around the blower casing 121. . The vertical rotation axis 210 is oriented at right angles to the rotation axis center line (X) and is used as a rotation center when the blower casing 121 rotates in the left and right horizontal directions. The vertical rotation axis 210 may be installed in a vertical direction with respect to the rotation axis of the blower motor 123 at the upper center of the casing hanger 310 supporting the blower casing 121, as shown in FIG. 1B.

The vertical rotation shaft 210 is supported and installed on the geared box 220. The geared box 220 supports rotation of the vertical rotation shaft 210 through a bearing 215. Therefore, the geared box 220 hangs the blower casing 121 on the installation surface 5 via the vertical rotation axis 210.

A ring gear 230 disposed in a geared box 220 is coupled to the top of the vertical rotation axis 210. The ring gear 230 has teeth 230a arranged in the circumferential direction on its upper surface.

The geared box 220 is equipped with a ring gear drive motor 240. A pinion gear 242 meshed with the teeth of the ring gear 230 is installed on the output shaft of the ring gear drive motor 240. Therefore, when the ring gear drive motor 240 is driven to rotate, the ring gear 230 meshes and rotates via the pinion gear 242, and at the same time, the blower casing 121 is vertically rotated by rotation of the vertical rotation shaft 210. It rotates in a horizontal state around the rotation axis 210.

Therefore, when the blower motor 123 is driven, the blowing wind generated by the axial flow blade 126 is discharged to a wide area along the left and right horizontal directions of the blower casing 121.

Here, in order to repeat the wind direction blowing from the blower casing 121 in a range of up to 90 degrees or 180 degrees, a pair of ring gear detection dogs installed at an angle of 90 degrees or 180 degrees are installed on the ring gear 230 as shown in FIG. 5. (232a, 232a) and a pair of ring gear detection dogs (232a, 232a) installed in the geared box 220 operate on/off to detect the rotation angle of the ring gear 230 at 90 degrees or 180 degrees. It may further include a pair of ring gear detection sensors (232b, 232b).

In this case, when the ring gear drive motor 240 is rotated, the direction is switched at the position where the pair of ring gear detection dogs (232a, 232a) and the pair of ring gear detection sensors (232b, 232b) detect each other, and the air blows. The casing 121 rotates reciprocally at an angle of 90 degrees or 180 degrees.

Meanwhile, as shown in FIGS. 6 and 7, the blower casing 121 is divided into a forward region (D) and a reverse region (R) divided by a vertical reference line (Y) passing through the center of the wing support 125, and the forward region Around (D), long holes 1211 for increasing forward inflow are arranged in the circumferential and axial directions so as to become larger toward the suction port 121a and smaller toward the discharge port 121b, and in the reverse region R. It may have a structure in which a long hole 1212 for increasing reverse inflow is formed around the circumference in a shape that is larger toward the discharge port 121b and smaller toward the suction port 121a.

Therefore, the blower can increase the ventilation power by allowing additional air to flow in through the long hole 1211 for increasing the inflow in the normal direction to increase the amount of air supply. In addition, the blower can rotate in the reverse direction in the event of a fire, allowing more smoke and toxic gas to flow in and be discharged to the outside through the long hole 1212 for increasing reverse inflow.

Meanwhile, in the present invention, in order to control the flow rate discharged from the blower casing 121 of the blower device, the blower casing 121 is installed concentrically on the outside of the blower casing 121 as shown in FIGS. 10 to 12 and 15. A discharge flow rate control casing (131) forming a second suction passage (131a) between the discharge flow rate control casing (131) and having a second positive direction inlet (131b) and a second reverse direction inlet (131c) arranged in a circle around the outer peripheral surface, and a second positive direction The forward discharge flow rate control door 132 is hinged to the discharge flow rate control casing 131 to open and close the inlet 131b, and the discharge flow rate control casing 131 is hinged to open and close the second reverse inlet 131c. It may include a reverse discharge flow rate control door 133, and first and second door operating means 141 and 142 for respectively rotating the forward discharge flow rate control door 132 and the reverse discharge flow rate control door 133.

Here, the second forward inlet (131b) and the second reverse inlet (131c) are slightly larger than the corresponding door behind the hinge to avoid collision when opening the closed discharge flow rate control door (132) and the second reverse inlet (131c). It is desirable to be configured.

The first door operating means 141 includes a first door motor 1411 fixedly installed on the discharge flow control casing 131, a first transfer screw 1412 directly connected to the rotation axis of the first door motor 1411, and A transfer block 1413 that is screwed to the first transfer screw 1412 and moves linearly, a synchro ring 1414 coaxially inserted into the outside of the discharge flow control casing 131 and hinged to the transfer block 1413, and , one end of which is hingedly connected to the synchro ring 1414 and the other end of which is hingedly connected to the forward discharge flow rate control door 132 to open and close the forward discharge flow rate control door 132 according to the rotation direction of the first door motor 1411. It may consist of 1 door lever 1415.

Therefore, when the first door motor 1411 of FIG. 13 is driven while the forward discharge flow rate control door 132 is closed, the transfer block 1413 moves linearly on the first transfer screw 1412 and at the same time synchro ring 1414 moves forward and all the forward discharge flow control doors 132 hinged to the synchro ring 1414 as shown in FIG. 14 are opened simultaneously, thereby increasing the amount of inflow into the blower casing 121, thereby increasing the air supply amount (Q1). This improves ventilation performance.

As such, according to the present invention, there is no risk of malfunction and the manufacturing cost can be reduced by having a simple structure that can simultaneously open the forward discharge flow rate control doors 132 arranged in a circular manner in the blower.

Meanwhile, as shown in FIGS. 12 and 13, the second door operating means 142 is directly connected to the second door motor 1421 fixed to the discharge flow control casing 131 and the rotation axis of the second door motor 1421. A second transfer screw 1422, a transfer block 1423 that is screwed to the second transfer screw 1422 and moves linearly, and a transfer block 1423 that is coaxially inserted into the outside of the casing 131 for controlling the discharge flow rate. A synchro ring 1424 that is hinged to, one end of which is hingedly connected to the synchro ring 1424 and the other end of which is hingedly connected to the door 132 for controlling the forward discharge flow rate, adjusts the forward discharge flow rate according to the rotation direction of the second door motor 1421. It may be composed of a second door lever 1425 that opens and closes the control door 132.

Therefore, when the second door motor 1421 is driven while the reverse discharge flow rate control door 133 is closed, the second transfer block 1423 moves linearly on the second transfer screw 1422 and at the same time the second synchro ring 1424 ) moves rearward, and all the reverse discharge flow control doors 133 hinged to the second synchro ring 1424 as shown in FIG. 13 are opened simultaneously, thereby increasing the inflow into the blower casing 121, thereby increasing the exhaust (smoke and smoke) in the event of a fire. It can increase the amount of toxic gas emissions (Q2).

<Second Embodiment>

Meanwhile, the second embodiment of the present invention is provided with the same blower casing 121, blower motor 123, vertical rotation shaft 210, and geared box 220 as the first embodiment, and blows air while rotating left and right horizontally. However, it is possible to rotate the blower casing 121 intermittently.

For this purpose, as shown in FIGS. 16 to 18, it is coupled to the upper end of the vertical rotation shaft 210, and the cam grooves 252b are continuously arranged between the protruding cam 252a and the adjacent protruding cam in the circumferential direction on the upper surface. An intermittent cam gear 250 and a fixed arm 262 that rotates and supports the intermittent cam gear 250 by positioning it on the inner peripheral surface, and whose end is located in the rotation radius of the protruding cam 252a above the intermittent cam gear 250. A cam gear housing 260 having one end rotatably coupled to the end of the fixed arm 262 and a cam pin 272 at the other end, the cam pin 272 is located on the outer peripheral surface of the protruding cam 252a at each rotation. A cam gear rotation lever 270 that rotates in revolution and rotates the intermittent cam gear 250 at a certain angle from the cam groove 252b, a small diameter driven gear 280 condensed to the other end of the rotation lever 270, and a geared box. A large-diameter drive gear 292 is mounted on (220) and meshed with a small-diameter driven gear 280 on the output shaft, and when rotationally driven, the blower casing 121 rotates in a horizontal state in one direction. It may include a cam gear drive motor 290 that allows blowing.

In this case, the blower casing 121 rotates horizontally in one direction, but after rotating by a certain angle, it pauses at the rotation position for a while and then rotates again.

That is, when the cam gear drive motor 290 rotates in one direction, the cam gear rotation lever 270 performs each rotation, and the cam pin 272 repeatedly moves the protruding cam 252a at a certain angle only in a certain contact section. Move it to Accordingly, the intermittent cam gear 250 performs an intermittent rotational movement, so that the blower casing 121 rotates by a certain angle, stops for a moment at the rotation position, and then repeats the rotation operation again. Even in this case, ventilation can be increased by wide and even blowing around the blowing casing 121.

Here, in order to repeat the wind direction blown from the blower casing 121 in a range of up to 90 degrees or 180 degrees, a pair of cam gear detection dogs installed at an angle of 90 degrees or 180 degrees on the intermittent cam gear 250 as shown in FIG. 19. (252a, 252a) and a pair of cam gear detection dogs (252a, 252a) installed in the geared box 220 are turned on/off to change the rotation angle of the intermittent cam gear 250 to 90 degrees or 180 degrees. A pair of cam gear detection sensors 252b and 252b may be further installed.

In this case, when the cam gear drive motor 290 is rotated, the direction is switched at the position where the pair of ring gear cam gear detection dogs (252a, 252a) and the pair of ring gear detection sensors (252b, 252b) detect each other. Thus, the blower casing 121 rotates reciprocally at an angle of 90 degrees or 180 degrees. Therefore, the ventilation casing 121 can effectively ventilate only the relevant area.

In the present invention, the on/off operation and driving direction of the ring gear drive motor 240, cam gear drive motor 290, and sector gear drive motor 370 can be remotely controlled using a remote controller (not shown).
