Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically a dustproof device for bridge demolition. Background Technology

[0002] A bridge is a structure built to meet the needs of convenient transportation. When a bridge ages or is damaged during its use, or when its location needs to be changed according to urban planning, it needs to be demolished to eliminate safety hazards, ensure public safety, and promote urban development and the construction of new transportation routes.

[0003] When bridge demolition work is carried out, in addition to isolating a safe zone, it is also necessary to take dust control measures to prevent the large amount of dust generated during bridge demolition from causing ecological damage and obstructing the view of the surrounding environment, as well as the impact of excessive dust on human health. A common dust control method at construction sites is to use a mist sprayer to spray a large amount of water mist or water particles. The water mist interacts with the dust particles suspended in the air, adsorbing, settling and wetting the dust particles, thereby reducing the concentration of dust in the air and purifying the air.

[0004] However, construction sites not only generate a large amount of dust, but also produce fine stone and sand particles during bridge demolition. Commonly, mist sprayers only have protective netting at the fan inlet to ensure sufficient airflow. If the gaps in the netting are too small, airflow becomes difficult, affecting the spraying effect. Therefore, when the mist sprayer is in operation, the netting alone can easily draw in sand and fine stone particles, which can then splash into the fan. This debris can damage internal components and blades during operation, increasing the probability of fan malfunction. Furthermore, if the fan malfunctions, water mist cannot be sprayed, causing backflow and further damage. Therefore, a dustproof device with protective features for the air inlet is needed for bridge demolition. Utility Model Content

[0005] The purpose of this invention is to provide a dustproof device for bridge demolition, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for bridge demolition, comprising a main body of a fog cannon, a movable mechanism for movement provided at the bottom of the main body of the fog cannon, a connecting pipe fixedly connected to the fan inlet end of the main body of the fog cannon, an air inlet box fixedly connected to the end of the connecting pipe away from the fan inlet of the main body of the fog cannon, a T-shaped cover plate provided on the top of the air inlet box, an air inlet slot provided on the side of the air inlet box away from the connecting pipe, a connecting plate fixedly connected to the inner wall of the air inlet box, a V-shaped air passage plate fixedly connected to one end of the connecting plate, a baffle fixedly connected to the end of the V-shaped air passage plate away from the connecting plate, a fixing plate fixedly connected to one side of the baffle, and the side of the fixing plate away from the baffle fixedly connected to the inner wall of the air inlet box, and a discharge pipe fixedly connected to the bottom of the air inlet box.

[0007] Preferably, the movable mechanism includes a connecting base frame and wheels. The top of the connecting base frame is fixedly connected to the bottom of the main body of the fog cannon. A support plate is fixedly connected to the bottom of the connecting base frame. A fixed shaft is fixedly connected through the center of the two wheels. The surface of the fixed shaft is rotatably connected through the side of the bottom end of the support plate.

[0008] Preferably, a V-shaped cotton board is fixedly connected to the inner side of the V-shaped air vent.

[0009] Preferably, the top of the air inlet box is threaded with a fixing bolt, and the air inlet box is threadedly fixed to the T-shaped cover plate by the fixing bolt.

[0010] Preferably, a support rod is fixedly connected to the bottom of one end of the connecting base plate frame, and a support foot is fixedly connected to the bottom of the support rod.

[0011] Preferably, the baffle is configured in a hook shape.

[0012] Preferably, the feed pipe is inclined downwards.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model incorporates a V-shaped air passage plate, a baffle, and a V-shaped cotton plate. The V-shaped air passage plate and baffle provide double-layer blocking for the airflow entering the air inlet box, thereby isolating sand or fine stones generated at the construction site from entering the main fan of the fog cannon. This ensures the airflow volume of the main fan while also protecting the fan. Simultaneously, the dehumidifying effect of the V-shaped cotton plate dries the incoming airflow and absorbs dust in the airflow through the moistened V-shaped cotton plate, further reducing the impact of dust and water mist on the internal components of the fan and ensuring the air delivery effect of the main fan of the fog cannon.

Detailed Implementation

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a dust suppression device for bridge demolition, comprising a main body 1 of a fog cannon, a movable mechanism for movement at the bottom of the main body 1, a connecting pipe 2 fixedly connected to the fan inlet of the main body 1, an air inlet box 4 fixedly connected to the end of the connecting pipe 2 away from the fan inlet of the main body 1, a T-shaped cover plate 3 on the top of the air inlet box 4, an air inlet slot 18 on the side of the air inlet box 4 away from the connecting pipe 2, a connecting plate 15 fixedly connected to the inner wall of the air inlet box 4, a V-shaped air passage plate 14 fixedly connected to one end of the connecting plate 15, a baffle 13 fixedly connected to the end of the V-shaped air passage plate 14 away from the connecting plate 15, a fixing plate 16 fixedly connected to one side of the baffle 13, and the side of the fixing plate 16 away from the baffle 13 fixedly connected to the inner wall of the air inlet box 4, and a discharge pipe 11 fixedly connected to the bottom of the air inlet box 4, which can filter the airflow entering the fan of the main body 1 of the fog cannon, satisfying the air intake while also playing an isolation role.

[0022] Furthermore, the moving mechanism includes a connecting base frame 10 and wheels 6. The top of the connecting base frame 10 is fixedly connected to the bottom of the main body 1 of the fog cannon. A support plate 5 is fixedly connected to the bottom of the connecting base frame 10. A fixed shaft 7 is fixedly connected through the center of the two wheels 6. The surface of the fixed shaft 7 is rotatably connected through the side of the bottom end of the support plate 5, which facilitates the movement of the device.

[0023] Furthermore, a V-shaped cotton plate 17 is fixedly connected to the inner side of the V-shaped air passage plate 14, which not only serves to dry the airflow but also improves the adhesion effect of the V-shaped cotton plate 17 to dust.

[0024] Furthermore, the top of the air inlet box 4 is threaded with a fixing bolt 12, and the air inlet box 4 is threadedly fixed to the T-shaped cover plate 3 by the fixing bolt 12, which facilitates the cleaning operation of the air inlet box 4.

[0025] Furthermore, a support rod 8 is fixedly connected to the bottom of one end of the connecting base plate frame 10, and a support foot 9 is fixedly connected to the bottom of the support rod 8, which facilitates the support and fixation operation of the device during use.

[0026] Furthermore, the baffle 13 is designed with a hook shape, which can provide a secondary blocking operation for sand or small stones.

[0027] Furthermore, the discharge pipe 11 is inclined downwards, so that when the top structure of the fog cannon body 1 is adjusted in angle, the discharge pipe 11 will still face downwards, thereby reducing the amount of sand or stone particles entering the air inlet box 4 from the discharge pipe 11.

[0028] Working principle: First, the device is connected to an external mobile device via the connecting base frame 10. The wheels 6 and fixed axle 7 move the device to the location requiring dust removal. The support rod 8 and support feet 9 then support and fix the front end of the connecting base frame 10. Next, the water inlet pipe is connected to an external water supply device. At this point, the fan and sprayer of the main body 1 of the fog cannon are started to perform dust removal. When the fan of the main body 1 of the fog cannon is in operation, the airflow enters the interior of the air inlet box 4 through the air inlet slot 18 on one side. Then, the airflow flows along the space between adjacent V-shaped air passage plates 14 and enters the connecting pipe 2 through the gap between the V-shaped air passage plate 14 and the fixed plate 16. The fan of the main body 1 of the fog cannon then completes the air delivery operation. When the airflow enters the air inlet box 4, due to the V-shaped design of the V-shaped air passage plate 14, sand particles or splashes within the airflow are blocked. Fine stone particles inside the air inlet box 4 are first partially blocked by the bend of the V-shaped air passage plate 14. Then, because the baffle 13 has a hook design and the length of the hook is equal to the length of the gap between the V-shaped air passage plate 14 and the fixed plate 16, the remaining particles are blocked by the hook of the baffle 13. This double-layer blocking operation can greatly reduce the possibility of sand or fine stone particles entering the fan of the main body 1 of the fog cannon. In addition, since the V-shaped air passage plate 14 is fixedly connected to the inner side, it can also adsorb water mist in the airflow, which can dry the airflow. At the same time, it can also improve the adhesion effect of the V-shaped cotton plate 17 to dust while keeping the V-shaped cotton plate 17 moist, thereby reducing the entry of dust into the fan of the main body 1 of the fog cannon and thus affecting the fan. Then, the blocked sand and fine stone particles will move downward along the inner side of the V-shaped air passage plate 14 or the baffle 13 and be discharged through the discharge pipe 11.
