Description

Technical Field

[0001] This utility model relates to the field of pipeline equipment technology, and in particular to a diversion ventilation duct. Background Technology

[0002] A split-flow ventilation duct is an important type of duct in a ventilation system. It has one or more branch structures, much like the trunk and branches of a tree. The main duct is like the trunk, responsible for transporting a large amount of air, while the branch ducts are like the branches, guiding the air to different areas or rooms, thus achieving air distribution.

[0003] In the prior art, such as Chinese Patent No. CN216112333U, "A Diverting Ventilation Duct", a diverting mechanism and a locking mechanism are included. The ventilation duct has a connecting and fixing plate on its left outer surface. A first diverting pipe is threadedly connected to the first diverting port on the right side of the front of the ventilation duct via a fixing bolt. A second diverting pipe is threadedly connected to the second diverting port on the right side of the rear of the ventilation duct via a fixing bolt. Rubber sealing blocks are provided in the through holes symmetrically arranged on both the front and rear sides of the upper surface of the ventilation duct. The diverting mechanism is located inside the ventilation duct. The locking mechanism is located in the middle of the upper surface of the ventilation duct and is threadedly connected to the rubber sealing blocks. This diverting ventilation duct can meet the different diversion needs of personnel, is simple to operate, greatly reduces the workload of staff, and can lock the diverting mechanism to prevent it from shifting due to excessive airflow within the ventilation duct.

[0004] In the aforementioned technologies, although locking mechanisms are used to lock each diversion mechanism to prevent the diversion mechanism from shifting due to excessive wind force in the ventilation duct, existing technologies typically involve directly opening the side of the main ventilation duct to install multiple diversion pipes when diversion pipes are needed in various situations. These diversion pipes are then fixed to solve the diversion problem. However, this makes subsequent maintenance and handling of diversion pipes that are no longer in use very troublesome. If they are disassembled, welding technology is required to patch the main ventilation duct, which may lead to air leakage, weakening the wind force of other diversion pipes and affecting the overall ventilation duct effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when diversion pipes are needed in various situations, the main ventilation duct is usually directly opened on the side to install multiple diversion pipes, and then the diversion pipes are fixed to solve the diversion problem. However, this will be very troublesome for later maintenance and when the diversion pipes are no longer used. If they are disassembled, welding technology is required to patch the main ventilation duct, which may cause air leakage, which will weaken the airflow of other diversion pipes and affect the overall ventilation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a diversion ventilation duct, comprising: a main ventilation duct body and a diversion duct body, wherein a motor is fixedly installed on the top of each of the two diversion duct bodies, a belt is movably sleeved on the outer surface of the output shaft of each of the two motors, a rotating shaft is movably embedded on the other side of each of the two belts, and a helical gear is movably connected to the top of each of the two rotating shafts; a helical rack is fixedly installed on the top of the main ventilation duct body, and one side of each of the two helical gears is meshed with the outer surfaces of both sides of the helical rack.

[0007] The technical effect of adopting the above-mentioned further solution is that the output shaft of the motor drives the rotating shaft to rotate through the belt, and the rotating shaft drives the helical gear to rotate synchronously. At this time, the helical gear meshes with the helical rack, and the helical rack drives the body of the diversion pipe to move through the helical gear.

[0008] In a preferred embodiment, a flange is fixedly installed on one side of the main ventilation duct body, and two movable grooves are opened on both sides of the inner wall of the main ventilation duct body. Two guide posts are fixedly connected inside each of the two movable grooves. The multiple guide posts are divided into two groups, and a sliding block is movably sleeved on the outer surface of each group of guide posts.

[0009] The technical effect of adopting the above-mentioned further solution is that the movement of the diversion pipe body drives the sliding block to move on the outer surface of the guide post one through the air control plate, and the guide post one initiates the guiding function when the sliding block moves.

[0010] In a preferred embodiment, a control plate is fixedly connected to one side of each of the two sliding blocks, and multiple drawers are fixedly installed on both sides of the main ventilation duct body. A drawer plate is movably connected to one side of each of the multiple drawers, and one side of each of the multiple drawers is fixedly connected to the outer surfaces of both sides of the two sliding blocks.

[0011] The technical effect of adopting the above-mentioned further solution is that: the sliding block is connected to the drawer plate on both sides, and when the sliding block moves, it drives the drawer plate to stretch and extend synchronously inside the drawer.

[0012] In a preferred embodiment, threaded rods are movably connected to the bottom of each of the two air control discs, turntables are movably connected to the bottom of each of the two threaded rods, limit plates are fixedly connected to the bottom of each of the two threaded rods, and filter plates are fixedly connected to the bottom of each of the two limit plates.

[0013] The technical effect of adopting the above-mentioned further solution is that by rotating the turntable, the limiting plate is moved through the threaded rod. When the filter plate is in the recess of the sliding block, the air force inside the diversion pipe body will be reduced. When the limiting plate is in the recess of the sliding block, the diversion pipe body will no longer provide air force.

[0014] In a preferred embodiment, a support block is fixedly connected to the bottom of each of the two diversion pipe bodies, and an inclined column is fixedly connected to one side of each of the two support blocks. Two fixing blocks are fixedly connected to the bottom of the main ventilation pipe body, and two guide columns are fixedly connected to the opposite side of the two fixing blocks. The two inclined columns are movably sleeved on the outer surface of the two guide columns.

[0015] The technical effect of adopting the above-mentioned further solution is that while the diversion pipe body moves, the support block slides on the outer surface of the guide column two through the inclined column for guidance, and the inclined column supports the diversion pipe body at the same time.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In use, the operator fixes the flange at the exhaust position, then adjusts the position of the diversion pipe body according to the desired diversion location, starts the motor, and the motor output shaft drives the rotating shaft to rotate via a belt. The rotating shaft drives the helical gear to rotate synchronously. The helical gear meshes with the helical rack, which in turn drives the diversion pipe body to move. While the diversion pipe body moves, the support block slides on the outer surface of the guide post two for support and guidance via the inclined column. The movement of the diversion pipe body is driven by the air control plate, which moves the sliding block on the outer surface of the guide post one. When the diversion pipe body moves, one side squeezes the draw plate and the other side pulls the draw plate inside the draw box, so that the draw plate always seals both sides of the main ventilation duct body, solving the problem of having to disassemble and reinstall the diversion pipe when changing its position.

[0018] 2. This utility model uses a rotating turntable to move a limiting plate via a threaded rod. When the filter plate is in the recess of the sliding block, the airflow inside the diversion pipe body will decrease. When the limiting plate is in the recess of the sliding block, the diversion pipe body will no longer provide airflow, thus solving the problem of needing to adjust the airflow in the diversion pipe.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a diversion ventilation duct, including: a main ventilation duct body 1 and a diversion duct body 110. A motor 111 is fixedly installed on the top of each of the two diversion duct bodies 110. A belt 112 is movably sleeved on the outer surface of the output shaft of each of the two motors 111. A rotating shaft 113 is movably embedded on the other side of each of the two belts 112. A helical gear 114 is movably connected to the top of each of the two rotating shafts 113. A helical rack 115 is fixedly installed on the top of the main ventilation duct body 1. One side of each of the two helical gears 114 is meshed with the outer surfaces of both sides of the helical rack 115. The output shaft of the motor 111 drives the rotating shaft 113 to rotate via the belt 112. The rotation of the rotating shaft 113 drives the helical gear 114 to rotate synchronously. The helical gear 114 meshes with the helical rack 115 at this time, and the helical rack 115 drives the diversion duct body 110 to move via the helical gear 114.

[0027] like Figure 1 As shown, a flange 101 is fixedly installed on one side of the main ventilation duct body 1. Two movable slots 102 are opened on both sides of the inner wall of the main ventilation duct body 1. Two guide columns 103 are fixedly connected inside the two movable slots 102. The multiple guide columns 103 are divided into two groups. A sliding block 104 is movably sleeved on the outer surface of each group of guide columns 103. The movement of the diversion duct body 110 drives the sliding block 104 to move on the outer surface of the guide column 103 through the air control plate 105. The guide column 103 activates the guiding effect when the sliding block 104 moves.

[0028] like Figure 2 As shown, a control plate 105 is fixedly connected to one side of each of the two sliding blocks 104. Multiple drawers 116 are fixedly installed on both sides of the main ventilation duct body 1. A drawer plate 117 is movably connected to one side of each of the multiple drawers 116. One side of each of the multiple drawers 117 is fixedly connected to the outer surfaces of both sides of the two sliding blocks 104. The drawers 117 are connected to both sides of the sliding blocks 104. When the sliding blocks 104 move, they drive the drawers 117 to stretch and extend synchronously inside the drawers 116.

[0029] like Figure 4 As shown, threaded rods 106 are movably connected to the bottom of each of the two air control discs 105, and turntables 107 are movably connected to the bottom of each of the two threaded rods 106. Limiting plates 108 are fixedly connected to the bottom of each of the two limiting plates 108, and filter plates 109 are fixedly connected to the bottom of each of the two limiting plates 108. By rotating the turntables 107, the limiting plates 108 are moved through the threaded rods 106. When the filter plate 109 is in the recess of the sliding block 104, the airflow inside the diversion pipe body 110 will be reduced. When the limiting plate 108 is in the recess of the sliding block 104, the diversion pipe body 110 will no longer provide airflow.

[0030] like Figure 3 As shown, support blocks 121 are fixedly connected to the bottom of both diversion pipe bodies 110, and inclined columns 120 are fixedly connected to one side of each of the two support blocks 121. Two fixing blocks 118 are fixedly connected to the bottom of the main ventilation pipe body 1, and two guide columns 119 are fixedly connected to the opposite side of the two fixing blocks 118. The two inclined columns 120 are movably sleeved on the outer surface of the two guide columns 119. While the diversion pipe body 110 moves, the support blocks 121 slide on the outer surface of the guide columns 119 through the inclined columns 120 for guidance. The inclined columns 120 simultaneously support the diversion pipe body 110.

[0031] Working Principle: This equipment is a diversion-type ventilation duct. During use, the operator fixes flange 101 at the exhaust position. Then, according to the desired diversion location, the position of the diversion duct body 110 is adjusted. The motor 111 is started, and its output shaft drives the rotating shaft 113 via belt 112. The rotating shaft 113 drives the helical gear 114 to rotate synchronously. The helical gear 114 meshes with the helical rack 115, which in turn moves the diversion duct body 110 via the helical gear 114. Simultaneously, the support block 121 slides on the outer surface of the guide post 119 via the inclined column 120 for support and guidance. The movement of the diversion duct body 110 is controlled by the air control plate 1. 05 drives the sliding block 104 to move on the outer surface of the guide post 103. When the diversion pipe body 110 moves, one side squeezes the draw plate 117 and the other side pulls the draw plate 117 inside the draw box 116, so that the draw plate 117 always seals the two sides of the main ventilation pipe body 1. This solves the problem of having to disassemble and reinstall the diversion pipe when changing its position. By rotating the turntable 107, the limiting plate 108 is moved through the threaded rod 106. When the filter plate 109 is in the recess of the sliding block 104, the air force inside the diversion pipe body 110 will be reduced. When the limiting plate 108 is in the recess of the sliding block 104, the diversion pipe body 110 will no longer provide air force. This solves the problem of having to adjust the air force in the diversion pipe.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
