Description

Technical Field

[0001] The utility model relates to the field of fire protection engineering, in particular to an automatic smoke exhaust device for fire protection engineering. Background Art

[0002] The existing automatic smoke exhaust device usually sets a filter at the air inlet of the smoke exhaust pipe, and filters the block floating objects in the thick smoke through the filter to prevent the block floating objects in the thick smoke from being directly discharged into the air. However, when the filter is clogged with too many block floating objects, the clogged filter will affect the smoke exhaust effect. Therefore, a scraper is usually used to scrape off the block floating objects attached to the filter to clear the filter.

[0003] However, when the scraper scrapes the bulk floating objects, the bulk floating objects will be squeezed and broken into small floating objects, and the small floating objects will pass through the mesh of the filter into the smoke exhaust pipe and then be directly discharged into the air, resulting in a large number of bulk floating objects still existing in the thick smoke discharged into the air. Utility Model Content

[0004] In order to overcome the disadvantage that bulk floating objects may be broken into small floating objects by being squeezed by a scraper, and the small floating objects may pass through the mesh of the filter screen and enter the smoke exhaust pipe, thereby causing a large number of bulk floating objects to still exist in the thick smoke discharged into the air, the utility model provides an automatic smoke exhaust device for fire protection engineering.

[0005] The technical solution is: an automatic smoke exhaust device for fire protection engineering, including a smoke exhaust pipe, a mounting plate, a fan and a motor; the smoke exhaust pipe is fixedly connected to the mounting plate; the mounting plate is rotatably connected to a fan for extracting indoor smoke into the smoke exhaust pipe; the mounting plate is fixedly connected to a motor; it also includes a reeling rod, a guide rod 1, a guide rod 2, a mounting belt, a filter, a motor 2 and a cleaning component; the smoke exhaust pipe is provided with two chambers distributed on the left and right; each chamber is rotatably connected to a reeling rod; two guide rods 1 distributed on the left and right are rotatably connected in the smoke exhaust pipe; the smoke exhaust pipe is rotatably connected to There are two guide rods 2 distributed on the left and right; the right winding rod is wound and fixedly connected to two mounting belts distributed front and back, and the free end of each mounting belt is successively passed around the right guide rod 1, the guide rod 2, the left guide rod 2 and the left guide rod 1 to be connected to the winding rod; the two mounting belts are jointly fixedly connected with a filter for filtering block floating objects in thick smoke; the smoke exhaust pipe is fixedly connected to two motors 2, and the output shaft of each motor 2 is fixedly connected to the corresponding winding rod; a cleaning component is connected to each chamber, and each cleaning component is connected to the corresponding winding rod.

[0006] As an improvement on the above scheme, the cleaning assembly includes a brush roller, pulley one and pulley two; a brush roller for cleaning bulk floating objects on the filter screen is rotatably connected in the chamber; the winding rod is fixedly connected to pulley one; the brush roller is fixedly connected to pulley two, and pulley two is connected to pulley one through a belt.

[0007] As an improvement of the above solution, a sponge board is also included; the two mounting belts are fixedly connected with the sponge board, and the sponge board is in contact with the upper surface of the filter screen.

[0008] As an improvement of the above scheme, a water pipe is also included; the smoke exhaust pipe is fixedly connected to two water pipes for moistening the sponge board, and the two water pipes are in contact with the sponge board.

[0009] As an improvement of the above scheme, it also includes a connecting belt; the left winding rod is wound and fixedly connected with two connecting belts distributed front and back, and each connecting belt is fixedly connected to the corresponding installation belt, and each installation belt is connected to the left winding rod through the corresponding connecting belt.

[0010] As an improvement to the above solution, both the mounting strap and the connecting strap are made of high temperature resistant material.

[0011] The utility model has the following advantages: by cooperating with two winding rods, the filter screen is located at the air inlet of the smoke exhaust pipe without cleaning, and the block floating objects can be filtered without clogging, so that the block floating objects are prevented from being squeezed by the scraper and broken into small floating objects, and the small floating objects will enter the smoke exhaust pipe through the mesh of the filter screen, thereby causing the problem that a large number of block floating objects still exist in the thick smoke discharged into the air;

[0012] The two reel rods cooperate to move the filter left and right, and at the same time, the brush roller brushes the floating objects attached to the filter into the chamber, so as to avoid the problem that when the part of the filter rolled up on the right reel rod is completely unrolled, the filter cannot continue to move to the left, that is, the filter is located at the air inlet of the smoke exhaust pipe and is no longer replaced, and the filter is difficult to maintain until the end of the fire.

[0013] The installation belt, filter and sponge board are completely rolled up onto the right rolling rod through the connecting belt. This can avoid the problem that the filter and sponge board are blocked at the air inlet of the smoke exhaust pipe, making it difficult for the fan to draw the thick smoke generated initially by the fire into the smoke exhaust pipe.

[0023] The cleaning assembly includes a brush roller 101, a pulley 102 and a pulley 2 103; the brush roller 101 is rotatably connected in the chamber 1a; the winding rod 5 is fixedly connected to the pulley 102; the brush roller 101 is fixedly connected to the pulley 2 103, and the pulley 2 103 is transmission-connected to the pulley 1 102 via a belt.

[0024] It also includes a sponge board 201 ; the two mounting belts 8 are fixedly connected with the sponge board 201 for enhancing the filtering effect of the block floating objects in the thick smoke, and the sponge board 201 is in contact with the upper surface of the filter screen 9 .

[0025] It also includes a water pipe 202 ; the smoke exhaust pipe 1 is fixedly connected to the two water pipes 202 , and the two water pipes 202 are in contact with the sponge board 201 .

[0026] The specific operation of the above embodiment 1 is as follows: First, the device is Figure 1 The vertical state shown is installed on the roof. At this time, the air outlet of the smoke exhaust pipe 1 is outdoors, and the air inlet of the smoke exhaust pipe 1 is indoors. Then, the external water delivery device is connected to the water delivery pipe 202 to complete the installation of the device.

[0027] When performing fire smoke exhaust, start the motor 14, and drive the fan 3 to rotate through the output shaft of the motor 14, so that the fan 3 draws the smoke in the room into the smoke exhaust pipe 1, and then exhausts it to the outside through the smoke exhaust pipe 1, thus completing the smoke exhaust work;

[0028] When smoke enters the smoke exhaust pipe 1, the block floating objects in the smoke are filtered by the filter 9 to prevent the block floating objects in the thick smoke from being directly discharged into the air;

[0029] It should be noted that when the filter screen 9 filters the block floating objects in the smoke, the following is based on the view from the front to the back. First, the output shaft of the right motor 2 10 is controlled to drive the right winding rod 5 to rotate counterclockwise, so that the right winding rod 5 continuously unwinds the mounting belt 8 and the filter screen 9. At the same time, the output shaft of the left motor 2 10 is controlled to drive the left winding rod 5 to rotate counterclockwise, so that the left winding rod 5 continuously rewinds the mounting belt 8 and the filter screen 9. In this way, the filter screen 9 is continuously moved to the left, and the position of the filter screen 9 at the air inlet of the smoke exhaust pipe 1 is continuously replaced, so that the position of the filter screen 9 at the air inlet of the smoke exhaust pipe 1 does not need to be cleaned, and the block floating objects can be filtered without clogging. In this way, the problem that the block floating objects are squeezed into small floating objects by the scraper in the prior art can be avoided, and the small floating objects will enter the smoke exhaust pipe 1 through the mesh of the filter screen 9, thereby causing a large number of block floating objects to still exist in the thick smoke discharged into the air.

[0030] Considering that if the indoor fire lasts for a relatively long time, if only the filter 9 moves to the left, that is, only the part of the filter 9 rolled up on the right winding rod 5 is used to filter a large number of block floating objects in the thick smoke, when the part of the filter 9 rolled up on the right winding rod 5 is completely unrolled, the filter 9 cannot continue to move to the left, that is, the part of the filter 9 at the air inlet of the smoke exhaust pipe 1 is no longer replaced, and it is difficult for the filter 9 to last until the fire is over;

[0031] Therefore, in the process of the left winding rod 5 winding up the mounting belt 8 and the filter screen 9, the following is the working process of the left cleaning assembly. The left winding rod 5 will drive the pulley 102 to rotate, and the pulley 102 will drive the pulley 2 103 through the belt, so that the pulley 2 103 drives the brush roller 101 to rotate. During the rotation of the brush roller 101, the brush roller 101 will continuously brush the block floating objects attached to the filter screen 9 into the left chamber 1a, thereby completing the cleaning work of the block floating objects attached to the filter screen 9;

[0032] When the filter screen 9 rolled up on the right winding rod 5 is completely unwound, that is, the filter screen 9 rolled up on the right winding rod 5 is rolled up on the left winding rod 5, the following is based on the front and back view, and the two motors 10 drive the corresponding winding rods 5 to rotate clockwise, so that the left winding rod 5 continuously unwinds the filter screen 9, and the right winding rod 5 continuously rewinds the filter screen 9, so that the filter screen 9 continuously moves to the right, and during the process of the filter screen 9 moving to the right, the right cleaning component will move in the same direction as the left cleaning component The block floating objects attached to the filter screen 9 are brushed into the right chamber 1a, and when the part of the filter screen 9 rolled up on the left rolling rod 5 is rolled up again on the right rolling rod 5, the filter screen 9 is moved to the left again in the same way as above. Such repeated movement can avoid the problem that when the part of the filter screen 9 rolled up on the right rolling rod 5 is completely unrolled, the filter screen 9 cannot continue to move to the left, that is, the filter screen 9 is located at the air inlet of the smoke exhaust pipe 1 and is no longer replaced, and the filter screen 9 is difficult to maintain until the end of the fire.

[0033] It should be noted that, in the process of filtering the block floating objects in the smoke, the filter screen 9 can enhance the filtering effect of the block floating objects in the thick smoke through the sponge board 201. At the same time, since the sponge board 201 is installed on the mounting belt 8, the sponge board 201 will also move synchronously during the process of the filter screen 9 moving to the left. Therefore, the sponge board 201 at the air inlet of the smoke exhaust pipe 1 can also continuously enhance the filtering effect of the block floating objects in the thick smoke.

[0034] Since the sponge board 201 is in contact with the upper surface of the filter screen 9, the brush roller 101 is in contact with the sponge board 201, and the brush roller 101 can also brush the floating block attached to the sponge board 201 into the chamber 1a, so that the sponge board 201 can also be maintained until the fire is over;

[0035] It should be noted that, when the sponge board 201 moves to the left, the external water delivery device is controlled to deliver water to the water delivery pipe 202 on the right, and then the water flows into the sponge board 201 through the water delivery pipe 202, so that the sponge board 201 is in a moist state. When the thick smoke passes through the sponge board 201, most of the heat in the thick smoke will be absorbed by the water in the sponge board 201, thereby achieving the effect of cooling the thick smoke, so as to avoid the problem that the thick smoke in a high temperature state enters the smoke exhaust pipe 1, which is easy to affect the normal operation of the device;

[0036] When the sponge board 201 moves to the right, the sponge board 201 is kept wet in the same manner as above.

[0037] Embodiment 2: Based on embodiment 1, Figure 4As shown, it also includes a connecting belt 301; the left winding rod 5 is wound and fixedly connected with two connecting belts 301 distributed front and back, and each connecting belt 301 is fixedly connected to the corresponding mounting belt 8, and each mounting belt 8 is connected to the left winding rod 5 through the corresponding connecting belt 301.

[0038] The mounting belt 8 and the connecting belt 301 are both made of high temperature resistant materials.

[0039] The specific operation of the above-mentioned embodiment 2 is as follows: After the device is installed on the roof, if the filter screen 9 and the sponge board 201 are in a state of Figure 1 In the state shown, a large amount of dust will inevitably adhere to the filter screen 9 and the sponge plate 201 at the air inlet of the smoke exhaust pipe 1. When a fire occurs, since the filter screen 9 and the sponge plate 201 at the air inlet of the smoke exhaust pipe 1 are blocked, it is difficult for the fan 3 to draw the thick smoke generated by the fire into the smoke exhaust pipe 1.

[0040] Therefore, when no fire occurs, the following is taken as a reference from front to back, and the two motors 10 drive the corresponding winding rods 5 to rotate clockwise, so that the right winding rod 5 continuously winds up the installation belt 8, filter screen 9 and sponge board 201, while the left winding rod 5 continuously unwinds the connecting belt 301 until the installation belt 8, filter screen 9 and sponge board 201 are completely wound onto the right winding rod 5. In this way, the problem that the filter screen 9 and sponge board 201 are blocked at the air inlet of the smoke exhaust pipe 1, making it difficult for the fan 3 to draw the thick smoke generated by the fire into the smoke exhaust pipe 1 can be avoided.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
