Description

[0001] 1. Technical Field: This innovative invention belongs to the field of fire protection technology, specifically an outdoor fire protection device used to prevent fires in forests, houses, etc., and to extinguish and block the spread of already burning fires.

[0002] 2. Background Technology: Fires have always threatened life and property on Earth. Especially outdoors, forest fires occur almost every year. Some forest fires are almost beyond human control, and can only be controlled and extinguished by favorable weather and geographical conditions. The losses caused by forest fires in Australia, Canada, the United States, and other countries every year are very serious, and they also cause great damage to the environment.

[0003] 3. Summary of the Invention: This innovative invention is a method for constructing an outdoor firewall, consisting of vertical poles and a central partition. The firewall can be raised and lowered manually or electrically, preventing the spread of forest fires and limiting their large-scale spread.

[0004] The vertical poles can be made of metals such as iron, steel, and aluminum, and coated with anti-rust paint, fire-retardant paint, etc. They can be manufactured into standard-sized base sections, intermediate sections, and apex sections. In use, the sections are assembled and fixed to the soil using recyclable soil expansion bolts through diagonal braces or diagonal lines of each section and ground-entry cones and X-shaped side wings of the base section. Their main function is to support the intermediate partitions.

[0005] The intermediate partition is made of asbestos fiber cloth, netting, or metal mesh such as iron sheet, steel sheet, aluminum sheet, or roller shutter. It is taller than the nearby trees and its main function is to prevent fire and block flames from spreading to other trees. 4. Description of the attached drawings

[0043] Figure 12 Figures A and B are shown. In Figure A, the pull line (94) is adjusted to the locked position. The spring (101) is pulled by the pull line (94) to the top of the buckles (98) and (102). Under the elastic force of the spring body (101), the buckles (98) and (102) are pushed outward. The buckles (93) and (97) protrude outside the locking section (92). When the middle partition (2) is pulled upward, the buckles (93) and (97) have no resistance and the middle partition (2) can be pulled upward smoothly. However, when the middle partition (2) is pulled downward, the buckles (93) and (97) will extend out of the locking holes (69) and (72) on the side of the middle section and get stuck, preventing the middle partition (2) from falling back downward. Pull the pull line (94) down a certain distance, that is, pull the spring body (101) to the tail of the buckle (98) and buckle (102). At this time, the pull line (94) is adjusted to the unlock position, as shown in Figure B. Under the elastic force of the spring body (101), the buckle (98) and buckle (102) rotate around the fixed axis (99) and fixed (103), so that the buckle head retracts and the whole is retracted inside the buckle section (92). The middle section (2) can move up and down arbitrarily. Most importantly, the middle section (2) can be removed from the vertical rod (1).

[0044] The pull cable (94) and the pull cable fixing housing (100, 104) are an integral structure, just like the brake cable of an electric vehicle. 5. Detailed Implementation Methods

[0045] This outdoor firewall (such as) Figure 1 The structure consists of a vertical rod (1) and a middle partition (2). The vertical rod (1) can be made of metals such as iron, steel, and aluminum, and coated with anti-rust paint, fireproof paint, etc. It can be manufactured into a standard specification base section (11), middle section (9), and apex section (6). When in use, the sections are assembled and fixed to the soil on the ground by means of diagonal bracing rods or diagonal lines, such as diagonal lines (rods) (5), diagonal lines (rods) (6), etc., and the ground-entry cone (24) and X-shaped side wings (14) of the base section. Its main function is to support the middle partition (2).

[0046] The intermediate partition (2) is made of asbestos fiber cloth, netting, or metal mesh such as iron sheet, steel sheet, aluminum sheet, or roller blind. Its height is higher than that of nearby trees. Its main function is to prevent fire and block flames from spreading to other trees.

[0047] 5.1 Manufacturing vertical rods.

[0048] Vertical rod (e.g.) Figure 2Made of metals such as iron, stainless steel, and aluminum, and coated with fireproof paint and rustproof paint, it mainly supports the "wall". During production, it can be made into a standard specification base section (11), middle section (9) and top section (6). When in use, the middle section (6) can be added to achieve a higher height. Each section can be made into standard parts with heights of 1 meter, 2 meters, 5 meters, etc., to facilitate transportation, storage, and use. Each section is connected by buckles and slots, such as buckles (8). When installing or disassembling, press the button (7) to make the buckle (8) sink in, so that it can be easily inserted into or removed from the slot.

[0049] 5.1.1 Manufacturing the basic section.

[0050] Basic segment (e.g.) Figure 3 The tube has a slot (21). When connecting to the middle section (or the apex section), the U-shaped extension rod plug (75) of the middle section (or the apex section) is inserted into the hollow tube (20). The buckle (8) on the U-shaped extension rod plug (75) is engaged in the slot (21).

[0051] The two sides are provided with slot tracks (18), which are aligned vertically with the slot tracks of other sections to form a track. Because the stranding wheel (12) is to be installed in the base section, the slot track (18) is not provided in this area to facilitate the operation of the stranding wheel (12). It is also convenient for the middle partition (2) to be inserted into the slot track (18) from here. The locking strips, blocks or points made on the edge of the middle partition (2) are used to tightly combine with the slot track to form a whole.

[0052] (I) Manufacturing of stranding reels.

[0053] The stranding wheel (12) can be operated manually or electrically. When operated manually, the stranding wheel (12) is cranked by the hand crank (19) to wind the pull wire, causing the partition to rise or fall. The stranding wheel can be located on the left and right sides of the vertical rod to control the partitions on the left and right sides respectively. Alternatively, it can be designed as a coaxial stranding wheel to save space. Coaxial stranded wire, such as... Figure 4 :

[0054] Figure 4 This is a side view of the coaxial winding wheel. The two winding wheels, which are separated by a middle section on both sides of the control rod, are set on the same rotating shaft. This not only saves space but also facilitates operation. When operating, pull the shaft (26) outward. At this time, the shaft controls the outer winding wheel. By cranking the hand crank (19), the outer winding wheel (29) can be rotated and the corresponding wire can be wound up. Conversely, by pushing the shaft (26) inward, the inner winding wheel (28) can be controlled. By cranking the hand crank (19), the inner winding wheel (28) can be rotated and the corresponding wire can be wound up.

[0055] The control principle is visible Figure 5 Internal structure:

[0056] Operating principle: Under normal circumstances, the winding wheel is locked by the interaction of the fixed internal toothed disc and cannot rotate. That is, for the inner winding wheel system, the spring (33) pushes out the fixing pin (32) and inserts it between the internal teeth of the inner fixed internal toothed disc (27), locking the inner winding wheel (28) so that it cannot rotate even under the reaction force of the pull line (4). Conversely, for the outer winding wheel system, the spring (43) pushes out the fixing pin (42) and inserts it between the internal teeth of the outer fixed internal toothed disc (30), locking the outer winding wheel (29) so that it cannot rotate. This is because the shaft (26) is not fixed to the winding wheel, and the shaft does not directly control the winding wheel; the winding wheel is controlled by the intermediate control ring. A hexagonal prism (40) is fixed in the middle of the shaft (26). During the process of pulling the shaft (26) outward and pushing it inward, the hexagonal prism (40) slides in the inner hexagonal space of the outer middle control ring (40) and the inner hexagonal space (37) of the inner middle control ring (36). When it moves into the inner hexagonal space (37) of the inner middle control ring (36), it can control the rotation of the inner winding wheel (28). Conversely, it controls the rotation of the outer winding wheel (29). Figure 5 After the shaft (26) is pulled outward, the hexagonal prism (40) on the shaft stops in the hexagonal space inside the outer middle control ring (41), and the hexagonal prism (40) fits into it. At this time, the hand crank (19) is turned to rotate the shaft (26). Under the force of the hexagonal prism (40), the middle control ring (41) rotates, and the steel wire cable (44) fixed on it is pulled. Because there is an arc space (45), the steel wire cable (44) will not be twisted, cut, or pulled apart. The steel wire cable (44) pulls the fixing pin (42) to move inward and get away from the obstruction of the inner teeth of the fixing inner toothed disc (30). At this time, the middle control ring (41) rotates a certain distance, and the protrusion (39) on it can push the winding wheel (29) to rotate, thereby realizing the winding or unwinding of the cable.

[0057] The structure of each component of the winding reel is as follows: Figure 6 .

[0058] Figure 6 illustrate: Figure 6 The winding wheel components are shown in only one set of inner winding wheel system, which includes an inner fixed internal gear disc, winding wheel, intermediate control ring and shaft. The shaft is shared by the inner and outer winding wheels because the inner and outer winding wheels have the same structure and the components can be interchanged. The only difference is that the inner components are installed in the opposite direction to the outer components.

[0059] During installation, the fixed internal gear disc (27) is fixed to the vertical rod wall and remains stationary. The protruding wheel (47) of the winding wheel (28) is installed inside the fixed internal gear disc (27). The intermediate control ring (36) is installed inside the winding wheel inner hole (51) of the winding wheel (28). At the same time, the fixing pin (32), spring (33), and steel wire cable (34) on it are installed in the round hole (48) on the protruding wheel (47), and the shaft (26) is installed inside the intermediate control ring (36).

[0060] Under normal circumstances, the retaining pin (32) is pushed out of the round hole (48) by the spring (33) and is locked between the internal teeth (46) of the retaining internal toothed disc (27), thus locking the winding wheel (28) in place. When the shaft (26) is pushed inward, it drives the hexagonal prism (40) to be inserted into the inner hexagonal space (37). The inner hexagonal space (37) is provided with a rounded edge (50) to facilitate the smooth insertion of the hexagonal prism (40) into the inner hexagonal space (37).

[0061] When the hexagonal prism (40) is rotated by the shaft (26), it drives the intermediate control ring (36) to rotate. The intermediate control ring (36) then pulls the steel wire cable (34) to retract, causing the fixing pin (32) to retract inward. When the fixing pin (32) is completely retracted into the round hole (48), the protrusion (38) on the intermediate control ring (36) just touches the protrusion (49) of the winding wheel (28) and pushes the winding wheel (28) to rotate.

[0062] The purpose of this design is to prevent the winding from rotating freely; only by actively rotating the shaft can the winding wheel be unlocked.

[0063] This structure reminds me of elevators. When elevators were invented, perhaps due to limitations in materials or convenience, the design concept of entrusting human lives to a steel cable is wrong. I have a safer invention concept. It also reminds me of airplanes. Whether commercial or military aircraft, they only pursue speed; once speed is lost, safety problems arise. Therefore, I have a safety mode for airplanes, but not a software safety mode, but a hardware safety mode. In this safety mode, the airplane will not crash. This safety mode, applied to civilian aircraft, can ensure the safety of countless people.

[0064] The base section has a long pointed cone (24) at its bottom, which can be directly inserted into the ground soil to fix the base section. The long pointed cone can be connected to the base section with screw threads, and can be disassembled when the ground is rocky. At the same time, an "X"-shaped side wing (14) is provided to increase the fixing area between the base section and the ground, and together with the long pointed cone, fixes the base section to the ground. The "X"-shaped side wing (14) is provided with a circular hole (23) and a rectangular hole (22) for nailing (stake) and screwing into the ground for fixing. The function of the circular hole (23) is that when encountering hard ground such as rock, ordinary expansion bolts can be driven into the ground through the circular hole (23) for fixing. In the case of soil ground in general forests, recyclable soil expansion bolts (15) can be driven into the soil through the rectangular hole (22).

[0065] Like the coaxial stranded wire reel, the recyclable soil expansion screw is an invention I made for use in outdoor firewalls.

[0066] (II) Manufacturing of recyclable soil expansion screws.

[0067] Recyclable soil expansion screws (such as Figure 7 This machine is suitable for soft ground such as soil and sand. To manufacture it, first, a long screw is made with a slightly larger screw cap (52). The screw rod (65) is fully threaded. A rectangular iron block (53) is made next to the lower edge of the screw cap (52), which can only rotate on the screw rod (65) but cannot move up or down. Then, four rectangular iron plates (56, 57, and 61) are made and chained together by shafts (58, 59, and 63). These plates are then chained together with the rectangular iron block (53) by shafts (54 and 55), allowing rotation at each shaft point. A screw cap or thread (62) is made in the middle of the knot between the iron plates (66 and 61), through which the screw rod (65) passes.

[0068] Working principle:

[0069] Figure 7 A is a schematic diagram of the entire recyclable soil expansion screw. Its size is adapted to the rectangular hole (22) on the "X"-shaped side wing (14) of the foundation section. When in use, the recyclable soil expansion screw is inserted into the soil through the rectangular hole (22). The iron plate (60) and iron plate (61) have blades at the joint, and the screw rod (65) has a pointed cone (64) at the end, so it can be inserted into the soil or driven into the soil. The screw cap (52) is large and is left on top. The rectangular iron block (53) is just placed in the rectangular hole (22). Rotating the screw cap (52) drives the screw rod (65) to rotate. Because it is tightened at the screw cap or thread (62), the iron plate (60) and iron plate (61) rise. As the rising distance increases, the iron plate (60) and iron plate (61) support the iron plate (56) and iron plate (57). At this time, the shape is as follows. Figure 7 B, the iron plates (56) and (57) expand outward, exerting pressure on the soil, thereby securing the entire recyclable soil expansion bolt, which in turn causes the "X"-shaped wing (14) to be secured.

[0070] During disassembly, reverse the screw cap (52) to reverse the screw rod (65), loosening the screw cap or thread (62). The iron plates (60) and (61) descend, causing the iron plates (56) and (57) to contract, thus forming a new shape. Figure 7 The A-shape allows for easy recycling of the entire screw.

[0071] When the entire recyclable soil expansion screw is in operation, the screw rod (65) inside only rotates and does not move up and down, causing the iron plates on both sides to contract and expand. Therefore, depending on the actual soil conditions, screws with two-sided expansion (in this example), three-sided expansion, and four-sided expansion can be designed to meet the needs of different types of soil, sand, quicksand, etc. To prevent rust, rust prevention measures should be taken, or stainless steel or other materials should be used.

[0072] 4.1.2 Manufacturing intermediate sections

[0073] The intermediate sections can be manufactured in standard lengths, such as 1 meter, 2 meters, or 5 meters per section. When in use, they are connected as needed. The "U"-shaped extension rod plug (75) is inserted into the hollow tube (20) of the base section to connect with the base section (the hollow tube (66) of the intermediate section is inserted to connect with the intermediate section), and the buckle (74) is inserted into the slot (21) of the base section. To disassemble, press the button (73), causing the buckle (74) to retract and disengage from the slot (21), allowing the "U"-shaped extension rod plug (75) to be pulled out of the hollow tube (20) of the base section. The operation mode is the same when connecting with other intermediate sections.

[0074] The function of the diagonal tie rod (line) slot (17) is to install the diagonal tie rod (line) in it to improve the stability of the vertical rod.

[0075] The function of the slot (68) is to lock the buckle (74) when connected to other intermediate segments, and to lock the buckle (8) when connected to the apex segment.

[0076] The space inside the side buckle groove (67) is reserved for the installation of the edge clips, clip segments, and clip points of the middle partition (2). The middle partition (2) is pulled along the groove track (18). The clips, clip segments, and clip points are equipped with buckles, which cooperate with the clip holes (69), clip holes (70), clip holes (71), and clip holes (72) to secure the middle partition.

[0077] 4.1.3 Creating Vertex Segments

[0078] like Figure 9Figure: 3. Pulley. 16. Diagonal tie rod (line) slot. 18. Slot track. 7. Button. 8. Buckle. 76. "U"-shaped extension rod plug.

[0079] 4.1.4 Manufacturing the tie rod

[0080] diagonal tie rods, such as Figure 10 It is also divided into basic segment, intermediate segment, and vertex segment.

[0081] 4.2 Manufacturing the intermediate partition

[0082] Intermediate partition such as Figure 11 Use asbestos fiber cloth or other fire-resistant materials. The intermediate partition can also be manufactured to standard specifications to match the dimensions of the vertical poles. The edges connecting to the vertical poles are equipped with retaining strips, segments, or points. Figure 11 The clips (91), clip segments (92), etc., are embedded in the side grooves of the vertical pole from bottom to top. There are no buckles (93) on the clips, clip segments, and clip points. When the middle partition is pulled to a certain position, the buckles are embedded in the clip holes (69), clip holes (70), clip holes (71), clip holes (72), etc., to fix the middle partition to both sides of the vertical pole. There are fixing holes (13), fixing holes (96), etc. below, which are directly nailed to the ground.

[0083] Figure 12 Figures A and B are shown. In Figure A, the pull line (94) is adjusted to the locked position. The spring (101) is pulled by the pull line (94) to the top of the buckles (98) and (102). Under the elastic force of the spring body (101), the buckles (98) and (102) are pushed outward. The buckles (93) and (97) protrude outside the locking section (92). When the middle partition (2) is pulled upward, the buckles (93) and (97) have no resistance and the middle partition (2) can be pulled upward smoothly. However, when the middle partition (2) is pulled downward, the buckles (93) and (97) will extend out of the locking holes (69) and (72) on the side of the middle section and get stuck, preventing the middle partition (2) from falling back downward. Pull the pull line (94) down a certain distance, that is, pull the spring body (101) to the tail of the buckle (98) and buckle (102). At this time, the pull line (94) is adjusted to the unlock position, as shown in Figure B. Under the elastic force of the spring body (101), the buckle (98) and buckle (102) rotate around the fixed axis (99) and fixed (103), so that the buckle head retracts and the whole is retracted inside the buckle section (92). The middle section (2) can move up and down arbitrarily. Most importantly, the middle section (2) can be removed from the vertical rod (1).

[0084] The pull cable (94) and the pull cable fixing housing (100, 104) are an integral structure, just like the brake cable of an electric vehicle.

[0085] 5. Advantages of this invention

[0086] 5.1 This innovative outdoor firewall consists of metal vertical poles and a fire-resistant intermediate partition. The vertical poles are made of metals such as iron, stainless steel, aluminum, and copper, and coated with fire-retardant and rust-proof paint. The intermediate partition is made of asbestos fiber cloth, iron, stainless steel, aluminum, copper, or waterproof materials. Both the vertical poles and the intermediate partition can be manufactured as standard components and can be produced in sections. It can be secured with tie rods (wires), long pointed cones, and "X"-shaped side wings using recyclable soil expansion bolts. The intermediate partition can be raised manually or electrically.

[0087] 5.2. Stranded wire pulleys, especially coaxial stranded wire pulleys. The retaining pin interacts with the fixed internal toothed disc to lock the stranded wire pulley at all times. Only when the shaft rotates actively, driving the intermediate control ring to rotate, pulling the steel wire cable on it, pulling the retaining pin inward, disengaging it from the fixed internal toothed disc, and driving the stranded wire pulley to rotate, can the rotation of the stranded wire pulley be controlled. At the same time, pulling the shaft outward and pushing it inward can control different stranded wire pulleys.

[0088] 5.3 Recyclable Soil Expansion Screws. The long screw has an iron plate on the outside. When the screw rotates, the iron plate rises or falls, and the iron plate exerts pressure on the soil it covers, thereby increasing the fastening area. It can be made into multi-sided expansion screws with two, three, or four sides, and is suitable for soil, sand, and other soft ground surfaces. It is also recyclable.

[0089] 5.4. Buckle Mechanism. The buckle is fixed by the shaft, while the spring body is not fixed and moves as required, forming different locking and unlocking functions, thus securing the middle partition and preventing it from slipping off.

Claims

1. The outdoor fireproof wall of the present invention is composed of metal vertical rods and intermediate partitions for fireproofing. The vertical rods are made of iron, stainless steel, aluminum, copper and other metals, coated with fireproof paint, rustproof paint and the like. The intermediate partitions are made of asbestos fiber cloth, iron, stainless steel, aluminum, copper and other metals or waterproof materials. The vertical rods and intermediate partitions can be made into rod standard parts and can be manufactured in sections. They can be fixed by pull rods (wires), long pointed cones and "X" type wings with recyclable soil expansion screws. The intermediate partitions can be manually or electrically lifted.

2. A wire winding wheel, especially a coaxial wire winding wheel. The fixing pin interacts with the fixed inner toothed disc to lock the wire winding wheel at any time. Only when the shaft is actively rotated to drive the intermediate control ring to rotate and pull the steel cable above it to pull the fixing pin inward to disengage from the fixed inner toothed disc and drive the wire winding wheel to rotate, can the wire winding wheel be controlled to rotate. At the same time, pulling outward and pushing inward of the shaft can control different wire winding wheels.

3. Recyclable soil expansion screws. The long screws have iron plates on the outside. The iron plates rise or fall under the rotation of the screws, and the iron plates generate pressure on the wrapped soil, thereby increasing the fastening area. The screws can be made into two-, three-, four- and multi-surface expansion screws, which can be applied to soil, sand and other sticky ground and can be recycled.

4. A buckle mechanism body. The buckle is fixed by the shaft, and the spring body is not fixed. It can be moved as required and form different locking and unlocking functions to lock the intermediate partition and prevent it from slipping.
