Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to a fire-fighting ventilation duct for garden construction. Background Art

[0002] Duct is a piping system used for air delivery and distribution. There are two types: composite duct and inorganic duct. Durkduct duct is the representative of composite duct. It can be classified according to cross-sectional shape and material. Duct production Stainless steel duct production is to apply sealant (such as neutral glass glue) to the seams such as the bite seams, rivet seams, and the four corners of the flange. The surface dust and oil should be removed before applying the sealant. According to the cross-sectional shape, ducts can be divided into circular ducts, rectangular ducts, oblate ducts and other types. Among them, circular ducts have the smallest resistance but the largest height size and are complex to make. Therefore, rectangular ducts are mainly used. According to the material, ducts can be divided into metal ducts, composite ducts, and polymer ducts.

[0003] The existing patent CN214307527U discloses a fire ventilation duct for garden construction, wherein an activated carbon filter plate is fixedly installed in the second ventilation duct, and a water-absorbing cotton net is arranged on the activated carbon filter plate away from the first ventilation duct. The activated carbon filter plate absorbs toxic gases in the air to prevent indoor personnel from absorbing toxic gases, and the water-absorbing cotton net absorbs moisture in the air to prevent air with excessive humidity from entering the room, causing indoor moisture resurgence, etc.

[0004] However, in this patent, only a filter plate with activated carbon is provided, which only protects dust before entering the ventilation duct. In addition, this patent does not design a treatment for dust that has already entered the ventilation duct, and the dust prevention effect is too simple, which cannot enable the ventilation duct to maintain a good ventilation effect under long-term use. At the same time, the filter plate will store a large amount of dust in the filter holes after long-term use, causing the filter holes to be blocked, which greatly affects the ventilation effect of the ventilation duct. Therefore, the utility model proposes a fire-fighting ventilation duct for garden construction. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] like Figure 1 and Figure 3 As shown, the utility model provides a technical solution: a fire-fighting ventilation duct for garden construction, comprising a first fire-fighting ventilation duct 1 and a second fire-fighting ventilation duct 2, a lifting assembly 4 is arranged in the first fire-fighting ventilation duct 1, the lifting assembly 4 comprises a first shell 42, a first screw 43 is arranged in the first shell 42, a fixing block 41 is fixedly connected to one end of the first shell 42, a motor 44 is fixedly connected to the end of the fixing block 41 away from the first screw 43, a first support frame 412 is fixedly connected to the fixing block 41, a second shell 49 is arranged in the second shell 49, A first screw rod 43 is provided, a first housing 42 and a second housing 49 are fixedly connected through a first connecting plate 410 and a second bolt 411, a sliding block 45 is movably connected to the first screw rod 43, a second support frame 46 is fixedly connected to the sliding block 45, four ends of the second support frame 46 are fixedly connected to mounting frames 47, a brush 48 is fixedly connected to the outer wall around the mounting frame 47, a first support frame 412 is fixedly connected to the fixing block 41, an end of the second housing 49 away from the motor 44 is fixedly connected to the first support frame 412, and an end of the second fire ventilation duct 2 away from the first fire ventilation duct 1 is fixedly connected to a filter assembly 5;

[0032] The length and width of the brush 48 are greater than the length and width of the first fire ventilation duct 1 and the second fire ventilation duct 2;

[0033] The first housing 42 and the second housing 49 are provided with sliding grooves of the same size as the second support frame 46 on all sides, and the first connecting plate 410 is provided with a second bolt 411, which penetrates the first connecting plate 410 and is fixedly connected to the first housing 42 and the second housing 49 on both sides;

[0034] The first fire ventilation duct 1 and the second fire ventilation duct 2 are fixedly connected to the first mounting plate 3 at one end close to the motor 44, and the first fire ventilation duct 1 is fixedly connected to the second mounting plate 7 at one end away from the motor 44. The first mounting plate 3 and the second mounting plate 7 are fixedly connected via a second connecting plate 8.

[0035] like Figure 2 As shown, the filter assembly 5 includes an air inlet 51, and a first filter plate 52 is arranged at one end of the air inlet 51 away from the second mounting plate 7. The air inlet 51 and the first filter plate 52 are fixedly connected to each other through a clamping plate 53 and a third bolt 54. A vibrator 55 is fixedly connected to one end of the air inlet 51, and a dust removal assembly 6 is movably connected to the bottom end of the second fire ventilation duct 2.

[0036] In this embodiment, the brush 48 sweeps away the dust remaining on the inner wall and stores it in the dust box 61, effectively removing the dust accumulated on the inner wall and reducing the risk of excessive dust accumulation affecting the air circulation in the pipe, which could cause a huge safety hazard. When the vibrator 55 vibrates, it shakes off the dust accumulated in the filter holes on the first filter plate 52 and drops it into the dust box 61, preventing the filter holes from being blocked and causing air to stagnate in the pipe, thereby causing a safety accident.

[0037] Example 2

[0038] like Figure 4 As shown, the second fire ventilation duct 2 and the second mounting plate 7 are provided with slots of the same size as the dust removal assembly 6;

[0039] The ash removal assembly 6 includes an ash storage box 61, two ends of the ash storage box 61 are fixedly connected to sliders 62, two ends of the ash storage box 61 away from the first screw 43 are fixedly connected to handles 63, and the inner wall of the end of the mounting frame 47 away from the brush 48 is fixedly connected to the dehumidification assembly 9;

[0040] like Figure 2 As shown in FIG. 5 , the dehumidification assembly 9 includes a storage box 91, which is symmetrically arranged and each storage box 91 has three second filter plates 92. A groove having the same size as the second filter plate 92 is provided on the storage box 91, and the second filter plate 92 is embedded and fixed in the groove provided on the storage box 91;

[0041] In this embodiment, after the dust has been stored for a period of time, the handle 63 is held, the dust box 61 is pulled out and then cleaned, which greatly reduces the workload of the staff and does not need to be cleaned at any time. The storage box 91 is placed with activated carbon material to absorb moisture in the ventilation duct to prevent the dust on the inner wall of the duct from coming into contact with water and being difficult to remove, thereby hindering the dust removal process.

[0042] Working principle:

[0043] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, when it is needed, the staff first turns on the motor 44, and the motor 44 drives the first screw 43 in the first housing 42 to start rotating. The sliding block 45 starts to move left and right due to the rotation of the first screw 43. Because the second support frame 46 is fixedly connected to the sliding block 45, and the second support frame 46 is fixedly connected to the mounting frame 47 and the brush 48, the sliding block 45, the second support frame 46, the mounting frame 47 and the brush 48 move synchronously with the start of the motor 44. During the movement, the brush 48 sweeps away the dust accumulated on the inner wall of the ventilation duct and stores it in the dust box 61. After a period of time, the vibration is turned on. The vibrator 55, the third bolt 54 and the first filter plate 52 are vibrated by the vibrator 55, and the dust accumulated in the filter holes of the first filter plate 52 is shaken off and falls into the ash box 61. Then, the staff holds the handle 63 to pull out the entire ash removal assembly 6 and clean the dust inside, which not only improves the dust removal efficiency but also greatly reduces the workload of the staff. In addition, the first fire ventilation duct 1 and the second fire ventilation duct 2 are connected by the first mounting plate 3 and the second mounting plate 7, and are fixedly fixed by the second connecting plate 8, which greatly increases the safety of the device and prevents the pipeline from falling off due to force and causing accidents.

[0044] like Figure 5 As shown, since the dehumidification component 9 is fixedly connected to the mounting frame 47, the dehumidification component 9 also moves synchronously with the mounting frame 47. During the movement, the activated carbon material placed in the dehumidification component 9 absorbs moisture in the pipeline to prevent dust on the inner wall of the pipeline from coming into contact with water and becoming difficult to remove, thereby hindering the dust removal process.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
