Description

Technical Field

[0001] The utility model relates to the field of hot work, in particular to a device for shielding wind and fire to reduce the risk of hot work. Background Art

[0002] In the hot work described in GB30871 "Safety Specifications for Special Operations in Hazardous Chemical Enterprises", spark splashing can be generated by: electric welding, gas cutting, cutting or grinding with a handheld grinder, plasma cutting, etc. At present, the commonly used fire control devices include: fire tray, fire blanket, fire barrier cloth, and fire extinguisher. There are many patents for fire trays that prevent sparks from splashing and intercept molten slag. Their structures include umbrella type, drawer type, etc. Most of them are relatively complex. The most commonly used fire trays (basins) are generally made of thin iron sheets, either supported or suspended, but it is difficult to select a fire receiving position that matches the hot work point at the work site. The hot work point is constantly changing, and it is even more difficult to adjust the position of the fire tray. Due to poor control of sparks during hot work or improper temperature control of objects around the work point, fires often occur. It is particularly important to extinguish the initial fire. In a small confined space, if a fire extinguisher is used, it will cause suffocation of the internal workers. Therefore, it is imperative to effectively reduce the risks of hot work. Utility Model Content

[0003] The utility model aims to solve the technical problem that the sparks of current hot work are parabolic and easily drift with the wind, resulting in poor spark control effect of the arranged fire basin, and provides a device for shielding wind and fire to reduce the risk of hot work.

[0004] The utility model is realized by adopting the following technical scheme: a device for shielding wind and fire and reducing the risk of hot work, comprising a fire receiving basin which also serves as a storage box; and at least two magnetic seats, one of the non-magnetic surfaces of the magnetic seats having a leg with an adjustable angle;

[0005] The same number of horizontal hanging rods as the number of magnetic bases are connected to the legs of each magnetic base respectively;

[0006] The suspended fire-blocking cloth has joints at at least two ends that can be sewed on the horizontal hanging rod.

[0007] Furthermore, fixing ears are respectively installed at the four corners of the outer bottom of the fire basin and are equipped with spring clips.

[0008] Furthermore, a box cover is provided at the top opening of the fire basin, and the box cover forms an inverted frustum-shaped structure when unfolded.

[0009] Furthermore, it also includes a fire basin lining made of flexible glass fiber fireproof cloth, and the shape of the fire basin lining is an inverted cone shape with a fold margin suitable for the fire basin.

[0010] Furthermore, it also includes an auxiliary fire blanket, one end of which is provided with a magnet.

[0011] Furthermore, an auxiliary watering can is also included.

[0012] The beneficial effects of the utility model are as follows: the wind and fire shielding kit is easy to carry; the mature technology magnetic seat is used as the original fulcrum of the fire basin, and the positioning is randomly variable; the storage box can be unfolded to form the main body of the fire basin, and the fire basin can be laid out in a variety of ways such as hanging fire-blocking cloth and directly lifting with a horizontal bar. It can also be combined into a fire bag when the space for hot work is limited; it is equipped with a water sprayer, which is small and convenient for operators and guardians to carry with them. It can spray direct current water jets to extinguish fires from a distance, and can also spray water to moisturize and cool down, taking fire protection into account, and reducing the frequency of use of fire extinguishers. In short, it can adapt to the diversity of hot work sites, ensure that the interception and storage of sparks, molten slag and impurities reaches 100%, and especially innovate the hot work management system: "Hot work must carry a water sprayer", which can greatly reduce the risk of hot work and is highly practical.

[0019] The fire point of hot work is always moving; hot work is easily affected by natural wind, and the falling sparks drift with the wind; in cutting operations, the splashing sparks are parabolic; all these reasons lead to the poor effect of controlling sparks by the fire basin; in the early stage of fire, relying on fire extinguishers to put out the fire has certain limitations and is expensive; after the hot work is completed, there are often smoldering fire hazards left at the work site. In order to solve the above technical problems, the utility model provides a device for shielding wind and fire to reduce the risk of hot work.

[0020] Embodiment 1 A device for shielding against wind and fire and reducing the risk of open flame operations, comprises a fire basin 5 which also serves as a storage box; further comprises at least two magnetic bases 1, each of which has legs 8 with adjustable angles; horizontal hanging rods 2 having the same number as the magnetic bases 1, respectively connected to the legs 8 of each magnetic base 1 (connected to a non-magnetic surface, generally connected to the surface opposite to the magnetic surface, and connected by a hinge connection or a universal ball joint); a suspended fire-blocking cloth 3, with joints sewn at both ends of the suspended fire-blocking cloth 3 that can be hung on the horizontal hanging rod 2; fixing ears 4 are respectively installed at the four corners of the outer bottom of the fire basin 5, and are provided with spring clips.

[0021] The two ends of the suspended fire-blocking cloth 3 are hung on the horizontal hanging rod 2, and the magnetic seat is adsorbed on the corresponding bracket 2 by magnetic force, so that the two ends of the suspended fire-blocking cloth 3 are suspended, and the fire basin 5 is placed on the suspended fire-blocking cloth 3, and the suspended fire-blocking cloth 3 can be connected with the fixing ears at the outer bottom of the fire basin 5 through spring clips.

[0022] Embodiment 2 The top opening of the fire basin 5 is provided with a box cover, which is unfolded to form an inverted cone-shaped structure. The fire basin lining 7 made of flexible glass fiber fireproof cloth is also included. The fire basin lining 7 is in the shape of an inverted cone with fold margins suitable for the fire basin 5.

[0023] like Figure 1-3 As shown, the fire basin 5 itself is in the shape of an inverted cone, and after the lids on the four sides of the top are opened, the whole structure is also in the shape of an inverted cone with a larger opening and a deeper structure, which increases the area for receiving sparks and can prevent sparks from falling outside the fire basin to a greater extent; the adjacent lids on the top of the fire basin can also be connected by a flexible refractory strip, so that after the fire basin lining 7 is unfolded and laid on the inside of the fire basin, there can be an additional support position. The lid can be installed on the side of the fire basin through a hinge and the installation position is lower than the top edge. Since the fire basin itself is in the shape of an inverted cone, the lid is blocked by the side of the fire basin after it is opened, forming a deeper inverted cone structure. Figure 2 , 3 In order to show the lining of the fire bowl, it is drawn in gray, indicating that the lining completely covers the inside of the fire bowl.

[0024] Embodiment 3 Based on the above embodiment, an auxiliary fire blanket 6 is further included, and one end of the auxiliary fire blanket 6 has a magnet. One end of the auxiliary fire blanket 6 is connected to the top edge of the fire basin, and the other end can be adsorbed on the weldment or other supporting parts near the site, further playing a role in preventing sparks.

[0025] Embodiment 4 Based on the above embodiment, an auxiliary water spray pot is further included. The above components can be stored in the fire basin at ordinary times, which is convenient for carrying and moving.

[0026] Figure 4As shown in the figure, two magnetic bases are adsorbed on both sides of the working point, and the suspended fire barrier cloth is hung up, and the fire basin is fixed on the suspended fire barrier cloth, below the working point. The suspended fire barrier cloth blocks the wind direction and the working point (that is, it is located on the wind direction of the working point), forming a double insurance with the fire basin.

[0027] like Figure 5 As shown, in order to further prevent sparks from leaving the fire basin area due to cutting and blowing, an auxiliary fire blanket can be connected to the top edge of the fire basin and the legs of a magnetic base to further prevent sparks and slag from scattering and flying away.

[0028] The innovation of the utility model is mainly reflected in: 1. Wind and fire shielding kit combination: fire basin lining, auxiliary fire blanket, suspended fire-blocking cloth, horizontal hanging rod, magnetic seat and auxiliary water spray pot. The storage box for storing the above items serves as the main body for storing sparks and slag, namely the fire basin. The box cover is unfolded to form an inverted cone shape to form an interception and collection surface that slopes toward the storage box. The receiving box and the box cover are lined with a fire-blocking lining. 2. Fire basin lining: The flexible glass fiber fire blanket is cut and sewn into an inverted cone shape with a wrinkle margin suitable for the fire basin. When in use, it is unfolded and clamped on the box cover, and sprayed with water to keep it moist, ensuring that the molten slag will not burn the fire blanket lining. 3. Fixing ears: Fixing ears are set at the four corners of the bottom of the fire basin (storage box) to clamp and fix the fire basin on the suspended fire-blocking cloth. 4. Magnetic seat: The magnetic force is controlled by the switch, the technology is mature, and it is easy to install and dismantle. It is used as the original fulcrum of the fire basin to be adsorbed on the rigid components around the operation point, and the supporting adjustable angle legs are clamped with the horizontal hanging rod. 5. Horizontal hanging rod: Fastened to the magnetic seat legs, it is used to carry the suspended fire barrier cloth. 6. Suspended fire barrier cloth: The joints sewn at both ends are hung on the horizontal hanging rod, suspended below the hot work point and in the wind direction of the hot work point, to carry the fire basin and reduce the impact of natural wind on the hot work; the auxiliary fire blanket can also be clamped and suspended in front of the cutting and sweeping direction to intercept the splashing molten slag. 7. Auxiliary fire blanket: One end has a magnet inside and can be adsorbed on the rigid component, and the other end is overlapped and clamped on the edge of the fire basin to cover the leak between the fire basin and the component. The second is to be clamped and suspended at a high place to intercept the splashing molten slag during the cutting operation. 8. Auxiliary water spray bottles can be used to spray atomized water on the lining of the fire basin and the auxiliary fire blanket to maintain humidity and extinguish molten welding slag in time. During hot work, water can be sprayed around the work point to cool down and eliminate fire hazards. If a fire occurs at the hot work site, the initial fire can be quickly extinguished. After the hot work is completed, the hot work point can be sprayed to prevent residual fire hazards. Fifth, "a water spray bottle must be carried during hot work" should be written into the hot work procedures to innovate the hot work management system.

[0029] Before the hot work, the magnetic base adsorption position is selected according to the hot work content, the wind direction of the hot work point and the distribution of rigid components on site. The magnetic base is used as the original support point (hanging point) of the fire basin, and the rigid aluminum horizontal hanging rod is clamped with the legs that can adjust the angle and position as the hanging point of the suspended fire barrier cloth. The fire basin is placed on the suspended fire barrier cloth. The four corners of the fire basin are provided with fixing ears, which are fastened to the suspended fire barrier cloth with spring clips (such as Figure 4 , 5 As shown in the figure, the legs can be adjusted immediately to adjust the position of the fire basin or rearrange the fire basin as the welding point changes; when the hot work point has little space to move, the fire basin can be directly lifted and clamped on the magnetic base horizontal hanging rod, or the fire basin lining can be directly clamped on the fire barrier cloth and the auxiliary fire blanket can be adsorbed on the weldment to form a fire bag. In short, the fire basin should be as close to the hot work point as possible without affecting the operation of the hot work person, and corresponding adjustments should be made when the wind direction changes or the cutting direction changes.

[0030] During the hot work, the supervisor should timely adjust the position of the fire basin and the suspended fire barrier cloth by observing the spark flying, wind direction and wind force changes. The hot work person and the supervisor should carry a watering can with them to deal with the fire in time.

[0031] After the hot work is completed, inspect the work site and use a spray bottle to spray the hot work site again to prevent any remaining fire hazards.

[0033] 1. The storage box is unfolded and combined into a fire basin;

[0034] 2. Use suspended fire-blocking cloth to support the fire basin;
