Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction safety, in particular to a material monitoring and automatic fire extinguishing device used in a construction site. Background Art

[0002] Currently, construction sites often store different materials by type, a significant portion of which is combustible (such as wooden formwork, timber, polystyrene boards, and waterproofing membranes). Once ignited by a spark, these materials often smolder before the fire spreads, making them difficult to detect. This can easily lead to unnecessary property damage and even serious safety hazards. The most common fire prevention measure currently used on construction sites is to assign dedicated personnel to monitor the site around the clock, often requiring at least three people on duty in shifts daily. This consumes a lot of manpower and incurs high labor costs. Summary of the Invention

[0003] The purpose of the utility model is to provide a material monitoring and automatic fire extinguishing device for construction sites in order to address the defects of the prior art.

[0004] In order to achieve the above purpose, the present invention can adopt the following technical solutions:

[0005] The material monitoring and automatic fire extinguishing device for construction sites of the present invention includes a supporting column, an electric rotating seat is provided at the upper end of the supporting column, a fire extinguishing bomb launcher with a magazine is provided on the electric rotating seat, and the magazine is filled with dry powder fire extinguishing bombs; a plurality of monitoring columns are arranged within the radiation range of the fire extinguishing bomb launcher, and a smoke detector electrically connected to the electric rotating seat is provided at the upper end of each monitoring column.

[0006] Furthermore, a fixing plate is provided at the lower end of the support column, and a plurality of anchor bolts are evenly distributed along the circumference of the fixing plate, so that the support column can be easily fixed to the ground and can be disassembled at any time as needed to move the support column.

[0007] Furthermore, a connecting wire protection tube is arranged on the ground between the supporting column and each of the monitoring columns. At this time, the connecting wire of the smoke detector electrically connected to the electric rotating seat passes through the connecting wire protection tube, effectively preventing the connecting wire from being stepped on or crushed.

[0008] The advantage of this utility model is that it can be reasonably arranged according to the material piles scattered on the construction site, and can quickly change the layout position as the position of the material pile changes, so that the smoke detector can be used to monitor in real time whether the material pile is ignited by sparks. In the smoldering stage before the fire spreads, the smoke can be accurately collected, and the fire extinguishing bomb launcher can be controlled in time to automatically launch dry powder fire extinguishing bombs to the smoldering material pile for extinguishing the fire. There is no need to send special personnel on duty, which saves manpower and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] 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.

[0013] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0014] like Figure 1 、 2 As shown, the material monitoring and automatic fire extinguishing device for construction sites described in the present invention includes a supporting column 1, an electric rotating seat 2 is provided at the upper end of the supporting column 1, a fire extinguishing bomb launcher 3 is provided on the electric rotating seat 2, and the fire extinguishing bomb launcher 3 has a bomb storage bin 4, and the bomb storage bin 4 is filled with dry powder fire extinguishing bombs 5.

[0015] A plurality of monitoring columns 6 are arranged within the radiation range of the dry powder fire extinguishing bomb 5 launched by the fire extinguishing bomb launcher 3. The number of monitoring columns 6 is determined according to the number of material piles 7 within the radiation range of the fire extinguishing bomb launcher 3, ensuring that each monitoring column 6 corresponds to a material pile 7; in addition, a smoke probe 8 electrically connected to the electric rotating seat 2 is provided at the upper end of each monitoring column 6, and the smoke probe 8 is used to monitor in real time the smoke generated when the material pile 7 is ignited by sparks or smolders.

[0016] Furthermore, in order to facilitate the installation and removal of the support column 1, as shown in FIG. Figure 3 As shown, a fixing plate 9 can also be coaxially arranged at the lower end of the support column 1, and a plurality of anchor bolts 10 can be evenly distributed along the circumference on the fixing plate 9 located on the outside of the support column 1. The anchor bolts 10 pass through the fixing plate 9 vertically from top to bottom and are anchored to the ground, thereby easily fixing the support column 1 to the ground, and the anchor bolts 10 can be removed at any time as needed, thereby moving the support column 1.

[0017] Furthermore, since the smoke detector 8 is often electrically connected to the electric rotating seat 2 through a connecting wire, a groove can be made on the ground between the supporting column 1 and each monitoring column 6 and a connecting wire protection tube 11 can be laid, so that the connecting wire between the smoke detector 8 and the electric rotating seat 2 can be passed through the connecting wire protection tube 11, effectively preventing the connecting wire from being stepped on or crushed.

[0018] During actual installation, first, the position of the supporting column 1 is reasonably arranged according to the material pile 7 that needs to be monitored for fire prevention, ensuring that the radiation range of the dry powder fire extinguishing bomb 5 launched by the fire extinguishing bomb launcher 3 on the supporting column 1 can cover all the material piles 7; then a monitoring column 6 can be set next to each material pile 7, and a connecting wire protection tube 11 can be buried on the ground between the supporting column 1 and each monitoring column 6; thereafter, the connecting wire of the smoke probe 8 at the upper end of the monitoring column 6 can be passed through the connecting wire protection tube 11 and connected to the electric rotating seat 2 at the upper end of the supporting column 1 to complete the installation and layout of the entire device; the entire device can be reasonably arranged according to the material piles 7 scattered on the construction site, and can quickly change the layout position as the position of the material pile 7 changes.

[0019] During actual use, the material pile 7 is monitored in real time through the smoke probe 8. When a material pile 7 is ignited by a spark, the smoke generated in the smoldering stage before the fire spreads will be detected by the smoke probe 8, and the monitoring signal will be transmitted to the electric rotating seat 2. At this time, the electric rotating seat 2 automatically rotates according to the signal, so that the fire extinguishing bomb launcher 3 on it launches dry powder fire extinguishing bombs 5 toward the material pile 7 where the smoke probe 8 detects smoke, thereby extinguishing the fire of the material pile 7. There is no need to send a special person to be on duty, which greatly saves manpower and reduces labor costs.
