Description

Elevator hoistway movement noise prevention system

The present invention relates to an elevator hoistway moving noise prevention system in which discharge dampers are installed at the upper and lower ends of an elevator moving passage to prevent noise by discharging air pressure formed inside the moving passage when an elevator car moves.

In addition, the present invention detects the noise generated by vibration when the elevator car passes the air supply damper installed on the building wall on one side of the elevator car door when using the elevator passage as an air supply airflow (air supply duct) in which the air supply damper of the ventilation area is installed. It relates to an elevator hoistway movement noise prevention system capable of minimizing noise by opening a discharge damper when it is higher than a decibel.

In general, an elevator is installed so that a moving passage is formed on one side wall of a building and then an elevator is moved by an electrical control device to transport people or cargo.

Since the moving passage of the elevator is raised and lowered while the upper and lower portions are closed, there is a problem in that noise is generated by compressed air as air is compressed while moving up and down when going up or down.

In particular, recently, since apartments and buildings are made up of high-rise buildings, when the elevator elevator moves, the strong air generated in the high-rise building rises or falls vertically, resulting in a stack effect. there is.

In addition, recently newly built high-rise buildings are being designed so that the passage of the elevator car can be used as a blowing duct without installing a separate blowing duct for blowing air to the air supply damper in case of fire.

In this way, when the elevator elevator moving passage is used as a blowing duct, the air supply damper installed in the control area is installed in each control area so that it is connected to the elevator moving passage, so the number of air supply dampers is installed as much as the number of each floor of the high-rise building.

At this time, there is a problem in that noise is generated due to a vibration caused by wind whenever an elevator car passes by a gap between the air supply damper installed to be connected to the elevator movement passage and the movement passage.

Looking at the prior art in this field, the low-noise elevator (hereinafter referred to as "prior art") of Patent Publication No. 10-2019-0027422 (published on March 15, 2019) is a cart installed at the bottom of the elevator and the above A first anti-vibration and soundproof member installed between the first beams fixing the cart to the elevator car and preventing noise and vibration generated as the hoist motor operates and transmitted to the cart through the wire rope from being transmitted to the elevator car; And a second dustproof and soundproof member installed between a second beam installed on the hoistway wall and the hoistway wall so that the hoist motor can be installed and preventing noise and vibration generated as the hoist motor operates from being transmitted to the hoistway wall. A configuration comprising the has been disclosed.

The prior art is installed between the cart and the first beam fixing the cart to the elevator to prevent noise and vibration generated as the hoist motor operates and transmitted to the cart through the wire rope from being transmitted to the elevator. However, there is a problem in that the noise generated by the compressed air formed while the elevator is moving up and down in the moving passage cannot be solved.

In addition, it appears that the prior art for solving the noise generated by the compression of the air formed while the elevator moves in the conventional elevator has not been searched.

Figure 4 is an excerpt showing the configuration of the connection between the pressure sensor and the wind noise sensor module connected to each discharge damper of the present invention.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

1 is a layout diagram showing a state in which the noise prevention system of the present invention is installed in an elevator passage, and is located outside the upper part of the moving passage 11 and the lower outside of the moving passage 11 in which the elevator car 10 is raised and lowered. The first discharge damper 20, the second discharge damper 21, the third discharge damper 22, and the fourth discharge damper 23 are installed.

At this time, the first discharge damper 20 and the second discharge damper 21 are installed in the external machine room so as to be connected to the upper end of the moving passage 11 of the elevator, and the third discharge damper 22 and the fourth discharge damper 23 is installed outside so as to be connected to the lower end of the moving passage 11 of the elevator.

In addition, the first sensor 30 and the second sensor composed of the discharge damper controller 40 of the first discharge damper 20 and the second discharge damper 21, the pressure sensor 34, and the wind noise sensor module 35 (31) are installed at predetermined intervals on the upper part of the moving passage 11, and the third discharge damper 22 and the fourth discharge damper 23 are spaced apart from the lower end of the moving passage 11 to the upper portion.

That is, for example, when the building has 25 floors, the first sensor 30 is installed between the 18th and 20th floors inside the moving passage 11, and the second sensor 31 is installed between the 22nd and 25th floors, The third sensor 32 is installed between the first and third floors, and the fourth sensor 33 is installed inside the moving passage 11 between the fourth and sixth floors.

In general, the elevator car 10 that goes up and down the movement passage 11 of the elevator has low noise when moving only from two to three floors, but when moving all floors, it is lifted from the first floor and operated at high speed. Air is concentrated between the 25th floor to form compressed air, and when moving from the upper floor to the lower floor, compressed air is formed between the 1st and 6th floors, so the noise is the largest when passing this section, so the sensor detects the compressed air Detects and transmits a signal to the discharge damper controller 40, and the discharge damper controller 40 opens the wings of the corresponding discharge damper to discharge the compressed air formed in the movement passage 11 to prevent noise from being generated. .

In particular, in the case of a newly built high-rise building, it is designed to use the elevator passage as an air supply airway (air supply duct) where the air supply damper of the control area is installed, so the air supply damper installed on the wall of the building on one side of the elevator car door trembles when the elevator car passes. The noise generated by the phenomenon is detected by the wind noise sensor module 35, and when the noise is higher than a certain decibel, the wind noise noise sensor module 35 and the wing of the exhaust damper connected to the wind noise are opened to minimize the noise.

The explanation of the number of floors of the building where the elevator moves is 25 floors is an example, and when installed in the moving passage 11 of an actual building, the compressed air layer formed in the moving passage 11 and the noise are reduced according to the height of the building. The first sensor 30 to the fourth sensor 33 are installed by measuring the decibel.

Connected to the discharge damper controller 40 of the first discharge damper 20, the second discharge damper 21, the third discharge damper 22, and the fourth discharge damper 23 to detect air pressure and noise The pressure sensor 34 and the wind noise sensor module 35 may be installed as a unit in one casing, or may be separately installed as needed.

It is installed in the first discharge damper 20, the second discharge damper 21, the third discharge damper 22, and the fourth discharge damper 23, respectively, to the pressure sensor 34 and the wind noise sensor module 35. When the signals detected by the first sensor 30, the second sensor 31, the third sensor 32, and the fourth sensor 33 are transmitted to each discharge damper controller 40, each discharge damper controller 40 ) is able to open and close the damper by transmitting a signal to the drive unit of each discharge damper.

In addition, the first discharge damper 20, the second discharge damper 21, the third discharge damper 22, and the fourth discharge damper 23 discharge smoke in the elevator moving passage 11 to the outside in case of fire, thereby eliminating smoke. It is possible to prevent smoke from entering the zone 50.

In addition, in case of fire, it is possible to maintain the differential pressure in the control zone 50 by controlling the air supply dampers 60 of each floor by blowing air to the elevator passage.

The first discharge damper 20 to the fourth discharge damper 23 generally have the same action as the air supply damper 60 installed in the control area 50 of the building and are formed in the moving passage 11 of the elevator Compressed air can be discharged, and in the event of a fire, the smoke from the fire control area 50 can flow into the movement passage 11 of the elevator and flow into the control area 50 of the other non-fire floor, so that the movement passage The smoke introduced into (11) is discharged to the outside using the first discharge damper 20, the second discharge damper 21, the third discharge damper 22, and the fourth discharge damper 23, thereby preventing a fire layer. of people can be prepared safely.

In general, the air supply damper 60 installed in the ventilation area 50 of the building is installed to be connected to the air supply airway at the front of the air supply windway, and the air supply damper according to the opening and closing of the indoor entrance door 61 or the emergency stair fire door in the ventilation area ( 60), if the differential pressure in the control zone 50 is recognized from the damper controller installed in the fire mode, and if the differential pressure is less than 40Pa, it is recognized as an evacuation mode.

However, in the present invention, when the elevator car 10 moving passage 11 is used to supply air without creating a separate air supply air passage, the air supply damper 60 generally installed in the air supply air passage is used as the elevator movement passage 11 It is installed to be connected to and used as an air supply damper 60 for firefighting.

The present invention normally acts to prevent noise generated by compressed air and vibration generated while the elevator passage 11 moves the elevator passage 11, but when a fire occurs in the building, the air supply damper 60 and Each discharge damper is changed to the fire mode to maintain the differential pressure in the smoke control area and the smoke discharge timing works.

In the present invention, each discharge damper and each air supply damper change to a fire mode in case of fire is made of the same system as the function used in the existing fire fighting system.

In this way, the air supply damper 60 having a dual mode is in a state where the entrance door of the control area is closed in the case of fire mode, but the pressure of the control area 50 is 40 Pa ~ Adjust the air volume of the blower to maintain the differential pressure at 60Pa.

The differential pressure of the air supplied to the control zone 50 through the air supply damper 60 is recognized as a fire mode when the differential pressure is detected as 40 Pa to 60 Pa by the sensor of the air supply damper, and recognized as an evacuation mode when the differential pressure drops below 40 Pa, , In the evacuation mode state, air is supplied at a smoke control area of the fire floor at a wind speed of 0.5 to 0.7 m/s.

When the air supply damper 60 is in the evacuation mode, the indoor entrance door 61 of the control area 60 or the fire door of the emergency stairway is temporarily opened while occupants of the building evacuate from the fire, and the opening of the door causes a fire. During the mode, the pressure maintained in the control zone drops rapidly.

As a result, there is a risk of smoke infiltrating and spreading into the smoke control area and non-fire floor, so smoke wind speed of 0.5 ~ 0.7m/s and indoor entrance door are applied to the control area of the evacuation layer of the fire floor to prevent smoke from penetrating and spreading to other spaces. (61) Control the air volume of the blower so that the differential pressure of 28Pa is maintained in the control area of the non-open floor to prevent the reduction of the smoke control wind speed flowing into the control area of the fire floor.

In this way, if the first to fourth discharge dampers having the function of the air supply damper 60 installed in the control area 50 are operated in conjunction with the air supply damper 60 and the blower (not shown) of the control area 50, the present invention The elevator hoistway moving noise prevention system of the present invention minimizes noise generated by operating the elevator car 10 and at the same time prevents smoke from spreading along with the air supply damper 60 installed in the control area 50 in case of fire. Personal injury can be prevented.

That is, since the upper and lower portions of the moving passage of the elevator are blocked, when the elevator car 10 moves up and down along the moving passage, the air is collected and compressed in the upper part of the moving passage 11, and thus the first sensor of the first discharge damper 20 The second sensor 31 of the 30 and the second discharge damper 21 detects compressed air and noise and sends a signal to the installed discharge damper controller 40, and the signal received by the discharge damper controller 40 is By determining the opening angle of the wings again, the wings of the first discharge damper 20 and the second discharge damper 21 are opened, so that air is discharged to the outside through the air inlet 25 connected to the moving passage 11. The noise of the elevator going up and down to the upper level of the aisle is minimized.

At this time, the third sensor 32 of the third discharge damper 22 and the fourth sensor 33 of the fourth discharge damper 23 installed at the lower end of the movement passage are also the first sensor 30 and the second sensor 31 When the elevator descends, the compressed air formed at the lower end of the moving passage is discharged to prevent noise.
