Description

Technical Field

[0001] The present invention relates to the technical field of forest fire prevention, and in particular to a forest fire prevention and extinguishing device and a use method thereof. Background Art

[0002] At present, since large mechanical equipment is difficult to enter when extinguishing forest fires, the fire-fighting equipment is mainly carried into the mountains by people. When the existing backpack high-pressure water mist fire extinguisher is carried forward, the water in the water tank shakes, requiring the personnel to maintain control balance, which will increase the physical expenditure. The patent document with the prior art publication number CN220676569U provides a labor-saving backpack fire-fighting device for forest fire fighting. The document gives a certain downward pressure to the float plate through a spring to reduce the shaking of the water surface. After the float plate moves up and down with the shaking of the water surface, there is a downward pressure resistance, thereby counteracting the shaking of the water surface, further reducing the shaking amplitude of the water body, and reducing the physical consumption of the user.

[0003] Although the above literature has many beneficial effects, the following problems still exist: the floating plate applies pressure to suppress the fluctuation of the water surface through the spring. Since the elastic force of the spring is different at different lengths, the floating plate is subjected to different pressures at different heights, so the suppression effect of the water surface fluctuation at different water levels is different, resulting in the inability to effectively suppress the fluctuation of the water surface at different water levels. Therefore, we propose a forest fire extinguishing device. Summary of the invention

[0004] In view of the fact that the elastic forces of the above-mentioned existing springs are different at different lengths, the floating plate is subjected to different pressures at different heights, resulting in different effects on suppressing water surface fluctuations at different water levels, which leads to the problem that effective fluctuation suppression of water surfaces at different water levels cannot be performed. The present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a forest fire extinguishing device, the purpose of which is to solve the problem that the elastic force of the spring is different at different lengths, so the pressure on the floating plate is different at different heights, resulting in different effects on suppressing water surface fluctuations at different water levels, resulting in the inability to effectively suppress fluctuations of water surfaces at different water levels.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a forest fire extinguishing device, comprising a backpack, a spray mechanism is installed at the lower part of the backpack, a water tank is installed at the upper part, the bottom of the water tank is connected to the spray mechanism, a plurality of partitions are fixedly connected in the water tank, the partitions cooperate with the water tank to form a plurality of water storage chambers, a floating plate is provided in the water storage chamber, and a positioning mechanism is installed on one of the floating plates;

[0011] As a preferred solution of the forest fire extinguishing device of the present invention, the spray mechanism includes a power pump, the input end of the power pump is connected to the water tank, and the output end is connected to the spray pipe through a hose.

[0012] As a preferred solution of the forest fire extinguishing device of the present invention, a plurality of the partitions are arranged at equal intervals, and through holes are opened on the partitions, and two adjacent floating plates pass through the through holes and are connected and fixed.

[0013] As a preferred solution of the forest fire extinguishing device described in the present invention, one side of the positioning block is provided with a tooth groove adapted to the positioning tooth plate, and the other side is fixedly connected to a U-shaped rod, a fixed seat is slidably connected to the U-shaped rod, the fixed seat is fixedly connected to a floating plate, and a spring is elastically connected between the positioning block and the fixed seat.

[0015] As a preferred solution of the forest fire extinguishing device of the present invention, the bottom of the buoyancy chamber is in abutment with a floating plate.

[0016] To achieve the above object, the present invention provides the following technical solution: a method for using a forest fire extinguishing device, comprising the following steps:

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Example 1

[0038] Reference Figure 1-6 , which is the first embodiment of the present invention, provides a forest fire extinguishing device, which includes a backpack 1, a spray mechanism 2 is installed at the lower part of the backpack 1, and a water tank 3 is installed at the upper part. The bottom of the water tank 3 is connected to the spray mechanism 2, and a plurality of partitions 4 are fixedly connected in the water tank 3. The partitions 4 and the water tank 3 cooperate to form a plurality of water storage chambers 5. A floating plate 6 is arranged in the water storage chamber 5, and a positioning mechanism 7 is installed on one of the floating plates 6.

[0039] The positioning mechanism 7 includes a positioning block 701 elastically connected to the floating plate 6, and a positioning tooth plate 702 is snap-fitted on one side of the positioning block 701. The positioning tooth plate 702 is fixedly connected to a partition 4, and the positioning mechanism 7 also includes a rotating rod 707, one end of the rotating rod 707 is fixedly connected to the buoyancy chamber 708, and the other end is transmission-connected to the positioning block 701.

[0040] In the above technical solution, when the spray mechanism 2 draws water from the water tank 3, the water level in the water tank 3 gradually decreases, the float plate 6 follows the water level drop and drives the positioning block 701 to drop, and when the positioning block 701 is engaged with the positioning tooth plate 702, the float plate 6 can be prohibited from sliding upward, so that the float plate 6 can use its own gravity to suppress fluctuations of water surfaces at different heights.

[0041] The backpack frame 1 includes a storage rack 101, one side of which is fixedly connected to a backpack plate 102, and a shoulder strap 103 is fixedly installed on the backpack plate 102. The storage rack 101 can be placed on the back of a person and carried and moved by the shoulder strap 103 carried on the shoulders of the person.

[0042] A cushion is fixedly provided on the side of the back plate 102 facing the person, so as to improve the fit and comfort of the back plate 102 with the person.

[0043] The spray mechanism 2 includes a power pump 201 , the input end of the power pump 201 is connected to the water tank 3 , and the output end is connected to a spray pipe 203 via a hose 202 .

[0044] In the above technical solution, the power pump 201 can be a gasoline engine pump or an electric motor pump. When the power pump 201 is working, the water in the water tank 3 is pumped into the spray pipe 203 through the hose 202, and is sprayed out through the atomizing nozzle at the end of the spray pipe 203 to extinguish the forest fire.

[0045] The plurality of partitions 4 are arranged at equal intervals, and a through hole 401 is opened on the partition 4, and two adjacent floating plates 6 pass through the through hole 401 and are connected and fixed.

[0046] In the above technical solution, the partition 4 cooperates with the water tank 3 to form a plurality of identical water storage chambers 5, so that the energy of the water surface shaking can be reduced, thereby reducing the amplitude of the water surface shaking. The through hole 401 facilitates the water level balance between two adjacent water storage chambers 5, and each float 6 is set at the same height to effectively suppress the water surface fluctuation.

[0047] One side of the positioning block 701 is provided with a tooth groove adapted to the positioning tooth plate 702, and the other side is fixedly connected to a U-shaped rod 703, and a fixing seat 704 is slidably connected to the U-shaped rod 703. The fixing seat 704 is fixedly connected to a floating plate 6, and a spring 705 is elastically connected between the positioning block 701 and the fixing seat 704.

[0048] In the above technical solution, when the floating plate 6 descends, the U-shaped rod 703 slides horizontally on the fixed seat 704, so that the positioning block 701 is disengaged from the positioning tooth plate 701, and then the spring 705 drives the positioning block 701 to engage with the positioning tooth plate 702 again, thereby limiting the upward sliding of the floating plate 6.

[0049] It is understandable that, referring to Figure 5 and Figure 6 The teeth and tooth grooves of the positioning tooth plate 702 are both in a right-angled triangle structure. When the floating plate 6 descends, the positioning block 701 is subjected to force to make the inclined surfaces of the tooth grooves slide and contact with the inclined surfaces of the teeth, so that the positioning block 701 itself slides out of place. When the floating plate 6 stops descending, the positioning block 701 moves to engage with the positioning tooth plate 702, and the top of the tooth groove abuts against the bottom of the tooth, which can prevent the floating plate 6 from moving upward.

[0050] The rotating rod 707 is rotatably connected to a floating plate 6 , one end of the rotating rod 707 is fixedly connected to the fixing rod 706 , and the fixing rod 706 is slidably connected to the U-shaped rod 703 .

[0051] In the above technical solution, when the water tank 3 is filled with water through the upper water inlet, the rising water level drives the buoyancy chamber 708 to rise, and the buoyancy chamber 708 drives the rotating rod 707 to rotate, so that the fixed rod 706 can drive the U-shaped rod 703 to move so that the positioning block 701 cancels the clamping connection with the positioning tooth plate 702, and the floating plate 6 can automatically rise as the water level increases.

[0052] The bottom of the buoyancy chamber 708 is in contact with a floating plate 6. When no water is added, the buoyancy chamber 708 is placed on the floating plate 6 due to the force of gravity, and the U-shaped rod 703 can slide automatically.

[0053] During use, the storage rack 1 can be carried on the back of a person through the shoulder strap 103. When the power pump 201 is turned on, the power pump 201 draws water from the water tank 3 and transports it to the spray pipe 203 through the hose 202. The water is sprayed out through the atomizing nozzle at the end of the spray pipe 203 to extinguish the forest fire. The float plate 6 follows the decrease in water level and drives the positioning block 701 to make way and slide downward on the positioning tooth plate 702. Then, when the float plate 6 stops descending, the spring 705 drives the positioning block 701 to engage with the positioning tooth plate 702 again, thereby limiting the upward movement of the float plate 6, so that the float plate 6 can effectively suppress the fluctuation of the water surface.

[0054] Example 2

[0055] Reference Figure 3, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a slide rail 104 connected and fixed to the back plate 102 is provided on one side of the shoulder strap 103, an adjustment seat 105 is slidably connected to the slide rail 104, a waist belt 106 is fixedly connected to the adjustment seat 105, a bolt 107 is threadedly connected to the adjustment seat 105, and one end of the bolt 107 is in abutment with the slide rail 104.

[0056] In the above technical solution, the adjustment seat 105 can slide on the slide rail 104 to adjust the height of the belt 106, and tightening the bolt 107 can limit the sliding of the adjustment seat 105. When the belt 106 is fixed to the waist of the person, it can share the weight of the person's shoulders and improve the stability of the connection between the rack 1 and the person.

[0057] The belt 106 is a Velcro strap, and the two belts 106 are glued together. The opposite sides of the two belts 106 are respectively provided with a Velcro fleece surface and a Velcro hook surface. The two belts 106 are glued together to quickly bind to a person.

[0058] The remaining structures are the same as those of Example 1.

[0059] Example 3

[0060] Reference Figure 1-6 , which is a fourth embodiment of the present invention, provides: a method for using a forest fire extinguishing device, comprising the following steps:

[0061] S1. The storage rack 101 is carried on the back of a person by means of a shoulder strap 103, and two waist belts 106 are glued and fixed to limit the storage rack 101;

[0062] S2, after the power pump 201 is turned on, the water in the water tank 3 is pumped out and transported to the spray pipe 203 through the hose 202, and then sprayed out through the spray pipe 203 to perform fire extinguishing work;

[0063] S3, the floating plate 6 drops synchronously with the water level in the water tank 3, and the gravity of the buoyancy 6 drives the positioning block 701 to automatically give way elastically, and then engages with the positioning tooth plate 702 again to prevent the floating plate 6 from moving upward;

[0064] S4. When water is added to the water tank 3, the buoyancy chamber 708 causes the rotating rod 707 to rotate, and the rotating rod 707 drives the positioning block 701 to disengage from the positioning tooth plate 702, and the floating plate 6 automatically rises with the water level.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
