Description

Technical Field

[0001] This utility model relates to the field of fire ventilation duct technology, and in particular to an anti-clogging carbon steel fire ventilation duct. Background Technology

[0002] Fire ventilation ducts made of carbon steel are pipes used in fire ventilation systems. These pipes are mainly used for air circulation, smoke exhaust, temperature control, and emergency ventilation in the event of a fire within a building.

[0003] Utility model patent CN221570768U discloses a fire ventilation duct. The key technical features are as follows: it includes a first duct and a second duct. The second duct is installed behind the first duct. Connecting blocks are installed at both ends of the first duct, and connecting brackets are provided at both ends of the first duct. A smoke exhaust duct is installed on the upper surface of the second duct. Connecting columns are fixedly connected to the lower left and right sides of the front end of the second duct. A sealing door is connected to the lower rear end of the second duct. A fixing plate is fixedly connected to the lower inner side of the second duct. An exhaust fan assembly is fixedly installed in the middle of the inner side of the second duct. A left-side fixing component is inserted through the middle of the connecting column at the left end of the vertical central axis of the first duct. This fire ventilation duct can filter dense smoke to a certain extent and allows for convenient periodic cleaning. It also provides convenient fastening during installation.

[0004] Regarding the above-mentioned issues, the following technical defects exist: Carbon steel fire ventilation ducts refer to ducts made of carbon steel used in fire ventilation systems. Ventilation ducts are mainly used for air circulation, smoke exhaust, temperature control, and emergency ventilation during fires within buildings. They have strong pressure resistance and high temperature resistance, and can maintain the normal operation of the ventilation system during a fire, helping to disperse smoke and ensure safety. However, these ventilation ducts do not have anti-clogging functions, which means that when the ventilation ducts are not in use, foreign objects can enter and cause blockages. This restricts the air circulation of the ventilation system, preventing smoke from being discharged in a timely manner, affecting the smoke exhaust effect during a fire, thereby increasing the fire risk and delaying evacuation time.

[0005] Therefore, it is necessary to provide a new type of anti-clogging carbon steel fire ventilation duct to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing ventilation ducts, which lack anti-clogging functions. This leads to blockages caused by foreign objects entering the ducts when not in use, restricting airflow and preventing timely smoke exhaust. Consequently, the smoke extraction effect during a fire is affected, increasing the fire risk and delaying evacuation time.

[0007] To solve the above-mentioned technical problems, this utility model provides an anti-clogging carbon steel fire ventilation duct, comprising: a ventilation duct body, an adjustment device provided on one side of the inner wall of the ventilation duct body, the adjustment device including a fixing plate, the fixing plate being fixedly connected to the bottom wall of the ventilation duct body, a connecting groove being opened on the side of the fixing plate, a connecting plate being slidably connected to the inner wall of the connecting groove, two fixing rods being fixedly connected to one side of the connecting plate, a filter plate being fixedly connected to the side of the two fixing rods that are close to each other, a support block being fixedly connected to one side of the filter plate, a rotating rod being threaded through the inner wall of the support block, and a positioning hole being opened on the connecting plate corresponding to the position of the rotating rod, the rotating rod being threaded through the inner wall of the positioning hole.

[0008] The aforementioned components achieve the following effects: The carbon steel fire ventilation duct body refers to the duct used in fire ventilation systems, which is made of carbon steel. The ventilation duct body is mainly used for air circulation, smoke exhaust, temperature control, and emergency ventilation during fires within buildings. They have strong pressure resistance and high temperature resistance, and can maintain the normal operation of the ventilation system during a fire, helping to disperse smoke and ensure safety. However, the ventilation duct body does not have an anti-clogging function, which means that when the ventilation duct body is not in use, foreign objects can enter the duct, causing blockages. This restricts the air circulation of the ventilation system, preventing smoke from being discharged in time, affecting the smoke exhaust effect during a fire, thereby increasing the fire risk and delaying evacuation time. At this time, an adjustment device can be installed on one side of the ventilation duct body. The adjustment device can block foreign objects, thereby improving the circulation effect of the entire ventilation duct body during use and improving the safety of the ventilation duct body during use.

[0009] Preferably, a plurality of anti-slip grooves are provided at one end of the arc surface of the rotating rod, and the plurality of anti-slip grooves are evenly distributed on the arc surface of the rotating rod.

[0010] The effect achieved by the above components is that when the rotating rod is rotated within the support block, the anti-slip groove on the rotating rod can increase the friction on the surface of the rotating rod, thereby improving the stability of the rotating rod rotating within the support block.

[0011] Preferably, a protective pad is fixedly connected to one end of the arc surface of the rotating rod, and the protective pad is in the shape of a ring.

[0012] The effect achieved by the above components is as follows: when the rotating rod rotates inside the support block and comes into contact with the support block, the protective pad installed on the rotating rod can prevent damage to the rotating rod from contacting the support block, and the protective pad can protect the contact position between the rotating rod and the support block.

[0013] Preferably, a guide rod is fixedly connected to the side wall of the connecting groove, and one end of the arc surface of the guide rod slides through the inner wall of the connecting plate.

[0014] The effect achieved by the above components is that when the connecting plate slides in the connecting groove, the guide rod installed in the connecting groove can improve the stability of the connecting plate sliding in the connecting groove.

[0015] Preferably, the fixing rod is a titanium alloy rod.

[0016] The effect achieved by the above components is that the fixing rod made of titanium alloy has a relatively hard surface, and it is less likely to deform even after long-term use, resulting in a longer service life.

[0017] Preferably, an auxiliary device is provided on the other side of the ventilation duct body. The auxiliary device includes a fixed frame, which is fixedly connected to one side of the ventilation duct body. A sliding rod is slidably connected to the inner wall of the fixed frame. A fixed block is fixedly connected to one end of the arc surface of the sliding rod. A cylinder is fixedly connected to the side of the fixed frame near the ventilation duct body. The output end of the cylinder is fixedly connected to the fixed block. A moving plate is slidably connected to the arc surface of the sliding rod.

[0018] The effect achieved by the above-mentioned components is that when it is necessary to connect two ventilation duct bodies, they can be connected quickly through the auxiliary device. Thus, the auxiliary device can improve the speed of connecting the two ventilation duct bodies, improve the connection efficiency, and shorten the time spent on the connection.

[0019] Preferably, a contact pad is fixedly connected to the side of the fixed frame near the moving plate.

[0020] The effect achieved by the above components is that when the moving plate drives one ventilation duct body to connect with another ventilation duct body, the contact pad installed on the fixed frame can protect the contact position between the two, thereby improving the stability of the connection between the two ventilation duct bodies.

[0021] Compared with related technologies, the anti-clogging carbon steel fire ventilation duct provided by this utility model has the following beneficial effects:

[0022] This utility model provides a clog-resistant carbon steel fire ventilation duct. By setting an adjustment device, when the ventilation duct is not in use, the unused duct opening can be protected by the adjustment device to prevent foreign objects from entering the duct opening and causing blockage when the ventilation duct is in use, thus affecting the effect of smoke evacuation during subsequent use.

[0023] By installing an auxiliary device, two ventilation ducts can be quickly connected, increasing the speed and efficiency of the connection and shortening the installation time. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6 The present invention provides an anti-clogging carbon steel fire ventilation duct, comprising: a ventilation duct body 1, an adjustment device 2 provided on one side of the inner wall of the ventilation duct body 1, and an auxiliary device 3 provided on the other side of the ventilation duct body 1.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes a fixing plate 201, which is fixedly connected to the bottom wall of the ventilation duct body 1. A connecting groove 202 is provided on the side of the fixing plate 201, and a connecting plate 203 is slidably connected to the inner wall of the connecting groove 202. Two fixing rods 204 are fixedly connected to one side of the connecting plate 203. A filter plate 205 is fixedly connected to the side of the two fixing rods 204 that are close to each other. A support block 206 is fixedly connected to one side of the filter plate 205. A rotating rod 207 is threaded through the inner wall of the support block 206. A positioning hole 208 is provided on the connecting plate 203 corresponding to the position of the rotating rod 207. The rotating rod 207 is threaded through the inner wall of the positioning hole 208. The carbon steel fire ventilation duct body 1 refers to a structure made of carbon steel. The ductwork used in fire ventilation systems, specifically the duct body 1, is primarily used for air circulation, smoke extraction, temperature control, and emergency ventilation during fires. It possesses strong pressure and high-temperature resistance, ensuring the ventilation system operates normally during a fire, aiding in smoke dispersal, and guaranteeing safety. However, the duct body 1 lacks anti-clogging capabilities. This means that when not in use, foreign objects can enter the duct, causing blockages. This restricts airflow, preventing timely smoke extraction and increasing fire risk, thus delaying evacuation. In such cases, an adjustment device 2 can be installed on one side of the duct body 1. This adjustment device allows for the removal of foreign objects. To improve the flow efficiency and safety of the entire ventilation duct body 1 during use, the rotating rod 207 has several anti-slip grooves 209 evenly distributed on its arc surface. When the rotating rod 207 rotates within the support block 206, the anti-slip grooves 209 increase the friction on its surface, thus improving its stability. A protective pad 210 is fixedly connected to one end of the arc surface of the rotating rod 207. The protective pad 210 is annular. When the rotating rod 207 rotates within the support block 206 and comes into contact with it, the rotating rod 207... The protective pad 210 installed on 07 can prevent damage from contact between the rotating rod 207 and the support block 206. The protective pad 210 can protect the contact position between the rotating rod 207 and the support block 206. A guide rod 211 is fixedly connected to the side wall of the connecting groove 202. One end of the arc surface of the guide rod 211 slides through the inner wall of the connecting plate 203. When the connecting plate 203 slides in the connecting groove 202, the guide rod 211 installed in the connecting groove 202 can improve the stability of the connecting plate 203 sliding in the connecting groove 202. The fixing rod 204 is a titanium alloy rod. The surface of the fixing rod 204 made of titanium alloy is relatively hard, and it is difficult for the surface of the rod to deform after long-term use, resulting in a long service life.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The auxiliary device 3 includes a fixed frame 31, which is fixedly connected to one side of the ventilation duct body 1. A sliding rod 32 is slidably connected to the inner wall of the fixed frame 31. A fixed block 33 is fixedly connected to one end of the arc surface of the sliding rod 32. A cylinder 34 is fixedly connected to the side of the fixed frame 31 near the ventilation duct body 1. The output end of the cylinder 34 is fixedly connected to the fixed block 33. A moving plate 35 is slidably connected to the arc surface of the sliding rod 32. When it is necessary to connect two ventilation duct bodies 1, they can be quickly connected through the auxiliary device 3. Thus, the auxiliary device 3 can improve the speed of connecting two ventilation duct bodies 1, improve the connection efficiency, and shorten the connection time. A contact pad 36 is fixedly connected to the side of the fixed frame 31 near the moving plate 35. When the moving plate 35 drives one ventilation duct body 1 to connect with another ventilation duct body 1, the contact pad 36 installed on the fixed frame 31 can protect the contact position between the two. Thus, the contact pad 36 can improve the stability of the connection between the two ventilation duct bodies 1.

[0036] The working principle of the anti-clogging carbon steel fire ventilation duct provided by this utility model is as follows: Connect the connecting plate 203 to the inner wall of the connecting groove 202. At this time, the filter plate 205 can be placed into the ventilation duct body 1. At this time, the rotating rod 207 can be rotated in the support block 206. The rotating rod 207 will connect with the inner wall of the positioning hole 208 through the inner wall of the fixing plate 201. At this time, the connecting plate 203 can be fixed in the connecting groove 202, and the filter plate 205 can be fixed in the ventilation duct body 1.

[0037] Slide the movable plate 35 upward on the sliding rod 32. At this time, one of the ventilation duct bodies 1 can be connected to the inner wall of the fixed frame 31. Then slide the movable plate 35 back to its original position. At this time, the cylinder 34 installed on the fixed frame 31 can be activated. The movement of the cylinder 34 will drive the fixed block 33 to move. The movement of the fixed block 33 will drive the sliding rod 32 to slide within the fixed frame 31. At this time, one of the ventilation duct bodies 1 can be brought into contact with the other ventilation duct body 1, and the two ventilation duct bodies 1 can be connected.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
