Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, in particular to a dry powder fire extinguisher. Background Art

[0002] Dry powder fire extinguishers can extinguish general fires and can also extinguish fires caused by combustion of oil, gas, etc. Dry powder fire extinguishers use carbon dioxide gas or nitrogen gas as power to eject the dry powder in the cylinder for fire extinguishing. Dry powder is a dry, easily flowing fine solid powder, which consists of a fire-extinguishing base material and additives such as a moisture-proof agent, a flow promoter, and an anti-caking agent. It is mainly used for extinguishing the initial fires of flammable liquids such as petroleum and organic solvents, combustible gases, and electrical equipment.

[0003] In a Chinese utility model patent with the publication number CN210751012U, a dry powder fire extinguisher is disclosed, which includes a dry powder fire extinguisher body placed on a bracket. A rotating frame for stabilizing and adjusting the angle of the nozzle of the dry powder fire extinguisher body is provided on the bracket, and a pusher for making the nozzle of the dry powder fire extinguisher body close to the ignition point when using the dry powder fire extinguisher body for fire extinguishing is also provided on the bracket. The rotating frame includes a front fixing rod fixed to the front side of the top of the bracket. A screw rod is fixed on the front fixing rod. The screw rod penetrates through one end of a swing rod. A sheep's horn nut for squeezing the swing rod is threadedly connected to the screw rod. A ring member is fixed to the other end of the swing rod. The nozzle of the dry powder fire extinguisher body is inserted into the ring member. A locking bolt for stabilizing the nozzle of the dry powder fire extinguisher body is threadedly connected to the ring member. By screwing the sheep's horn nut, the swing rod is stabilized on the front fixing rod, so that the nozzle is fixed. Then, the nozzle of the dry powder fire extinguisher body is pushed close to the ignition point through the pusher for fire extinguishing.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: During the fire extinguishing process, to ensure the fire extinguishing effect, it is usually necessary to swing the fire extinguisher nozzle to sweep the fire source. However, during the use of the above device, the nozzle is fixed first, and then the fire extinguishing operation is carried out. When adjusting the position of the nozzle, only by pushing the moving pusher can the position of the dry powder fire extinguisher body be changed to change the position of the nozzle. This adjustment method has obvious limitations, with a limited moving range and relatively laborious operation. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides a dry powder fire extinguisher.

[0006] The above technical object of the utility model is achieved by the following technical solutions: A dry powder fire extinguisher includes a moving frame and a fire extinguisher body disposed within the moving frame. A fixed frame is provided on the moving frame on one side of the valve nozzle of the fire extinguisher body. The fixed frame includes two horizontal bars arranged at intervals vertically and two vertical bars connecting the corresponding ends of the two horizontal bars. A vertical frame is slidably disposed between the two horizontal bars, and a horizontal frame is slidably disposed between the two vertical bars. First strip holes vertically arranged for the horizontal frame to pass through are formed on the left and right sides of the vertical frame. A square area is formed between the horizontal frame and the vertical frame, and a mounting seat is provided within the square area. The upper and lower ends of the mounting seat are slidably disposed on the upper and lower sides of the horizontal frame, and the left and right ends of the mounting seat are slidably disposed on the left and right sides of the vertical frame. A first pushing mechanism for pushing the horizontal frame to slide and a second pushing mechanism for pushing the vertical frame to slide are provided on the moving frame. A nozzle with a nozzle direction consistent with the valve nozzle direction of the fire extinguisher body is provided in the mounting seat. One end of the nozzle adjacent to the valve nozzle of the fire extinguisher body is connected to the valve nozzle of the fire extinguisher body through a connecting pipe.

[0007] By adopting the above technical solutions, with the moving frame, fire extinguisher body, fixed frame, vertical frame, horizontal frame, mounting seat, first pushing mechanism, and second pushing mechanism set, after discovering a fire in an area, the fire extinguisher body is moved to the fire area through the moving frame, and then the valve of the fire extinguisher body is opened, so that the dry powder in the fire extinguisher body reaches the nozzle through the connecting pipe and is ejected. The first pushing mechanism is used to push the horizontal frame to slide up and down, thereby driving the mounting seat to slide up and down within the vertical frame along with the horizontal frame, thus changing the up and down spraying position of the nozzle; the second pushing mechanism is used to push the vertical frame to slide left and right, thereby driving the mounting seat to slide left and right within the horizontal frame along with the vertical frame, thus changing the left and right spraying position of the nozzle, facilitating the adjustment of the position of the nozzle to achieve a better fire extinguishing effect.

[0008] Further, first sliding rods are horizontally arranged on the left and right sides of the mounting seat, and the first sliding rods are slidably disposed within the first strip holes.

[0009] By adopting the above technical solutions, first sliding rods are horizontally arranged on the left and right sides of the mounting seat to ensure the stability of the mounting seat sliding up and down within the vertical frame.

[0010] Further, second strip holes horizontally arranged are formed on the upper and lower sides of the horizontal frame, and second sliding rods are vertically arranged on the upper and lower sides of the mounting seat, and the second sliding rods are slidably disposed within the second strip holes.

[0011] By adopting the above technical solutions, the second strip holes and the second sliding rods are provided to ensure the stability of the mounting seat sliding left and right within the horizontal frame.

[0012] Further, third strip holes vertically arranged are formed on the vertical rods, and third sliding rods are horizontally arranged on the left and right sides of the horizontal frame, and the third sliding rods are slidably disposed within the third strip holes.

[0013] By adopting the above technical solution, the third strip-shaped hole and the third sliding rod are provided, ensuring the stability of the horizontal frame sliding up and down between the vertical rods.

[0014] Furthermore, the first pushing component includes two first positioning frames horizontally arranged at intervals on one side of the moving frame. A first pushing rod with a length direction consistent with the nozzle direction of the nozzle is slidably arranged in the two first positioning frames together. A first adjusting plate is arranged at one end of the first pushing rod close to the fixed frame. The plate surface of the first adjusting plate is in a vertical state and is arranged in a staggered manner with the vertical rod. A first adjusting groove is arranged along the length direction of the first adjusting plate. The end of the third sliding rod on the right side of the horizontal frame extends outwards and is slidably arranged in the first adjusting groove.

[0015] By adopting the above technical solution, the first positioning frame, the first pushing rod, the first adjusting plate, and the first adjusting groove are provided. Setting two first positioning frames ensures the stability of the sliding of the first pushing rod. By pulling the first pushing rod to drive the first adjusting plate to move back and forth, since the third sliding rod is restricted by the third strip-shaped hole to only slide up and down, when the first adjusting plate moves back and forth, the third sliding rod is always at the intersection of the third strip-shaped hole and the first adjusting groove, thereby driving the horizontal frame to slide up and down, and further driving the nozzle to move up and down.

[0016] Furthermore, a vertically arranged first threaded hole is formed in the first positioning frame far from the fixed frame. A first threaded rod is spirally arranged in the first threaded hole. The lower end of the first threaded rod abuts against the first pushing rod.

[0017] By adopting the above technical solution, the first threaded hole and the first threaded rod are provided. By screwing the first threaded rod, the first threaded rod moves up and down in the first threaded hole, making the lower end of the first threaded rod abut against or separate from the first pushing rod, facilitating the fixing of the first pushing rod.

[0018] Furthermore, a horizontally arranged fourth strip-shaped hole is formed in the cross bar. Fourth sliding rods are vertically arranged on the upper and lower sides of the vertical frame. The fourth sliding rods are slidably arranged in the fourth strip-shaped hole.

[0019] By adopting the above technical solution, the fourth strip-shaped hole and the fourth sliding rod are provided, ensuring the stability of the vertical frame sliding left and right between the cross bars.

[0020] Further, the second pushing assembly includes two second positioning frames arranged at a horizontal interval. The two second positioning frames are arranged on one side of the moving frame away from the first positioning frame. A second pushing rod with a length direction consistent with the nozzle direction of the nozzle is slidably arranged in the two second positioning frames in common. A second adjusting plate is arranged at one end of the second pushing rod close to the fixed frame. The plate surface of the second adjusting plate is in a horizontal state and is arranged in a staggered manner with the cross bar. A second adjusting groove is arranged along the length direction of the second adjusting plate. The end of the fourth sliding rod on the lower side of the vertical frame extends outwards and is slidably arranged in the second adjusting groove.

[0021] By adopting the above technical solution, the second positioning frame, the second pushing rod, the second adjusting plate and the second adjusting groove are provided. The setting of the two second positioning frames ensures the stability of the sliding of the second pushing rod. By pulling the second pushing rod to drive the second adjusting plate to move back and forth, since the fourth sliding rod is restricted by the fourth strip-shaped hole and can only slide left and right, when the second adjusting plate moves back and forth, the fourth sliding rod is always at the intersection of the fourth strip-shaped hole and the second adjusting groove, thereby driving the vertical frame to slide left and right, and further driving the nozzle to move left and right.

[0022] Further, a vertically arranged second threaded hole is opened on the second positioning frame away from the fixed frame. A second threaded rod is spirally arranged in the second threaded hole. The lower end of the second threaded rod abuts against the second pushing rod.

[0023] By adopting the above technical solution, the second threaded hole and the second threaded rod are provided. By screwing the second threaded rod, the second threaded rod moves up and down in the second threaded hole, so that the lower end of the second threaded rod abuts against or separates from the second pushing rod, which is convenient for fixing the second pushing rod.

[0024] In summary, the present utility model has the following beneficial effects: In this application, the moving frame, the fire extinguisher body, the fixed frame, the vertical frame, the cross frame, the mounting seat, the first pushing mechanism and the second pushing mechanism are provided. After discovering that there is a fire in a certain area, the fire extinguisher body is moved to the fire area through the moving frame, and then the valve of the fire extinguisher body is opened, so that the dry powder in the fire extinguisher body reaches the nozzle through the connecting pipe and is ejected. The first pushing is used to push the cross frame to slide up and down, thereby driving the mounting seat to slide up and down in the vertical frame along with the cross frame, so as to change the spraying position of the nozzle up and down; the second pushing mechanism is used to push the vertical frame to slide left and right, thereby driving the mounting seat to slide left and right in the cross frame along with the vertical frame, so as to change the left and right spraying positions of the nozzle, which is convenient for adjusting the position of the nozzle to achieve a better fire extinguishing effect.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Such as Figures 1-4As shown, the embodiment of the present application discloses a dry powder fire extinguisher, including a mobile frame 10, a fire extinguisher body 11, a fixed frame 20, a vertical frame 30, a horizontal frame 40, a mounting seat 50, a first pushing mechanism 60, and a second pushing mechanism 70. The fire extinguisher body 11 is placed in the mobile frame 10, and the direction in which the nozzle of the fire extinguisher body valve 12 faces is forward. A push handle is provided on the upper rear side of the mobile frame 10, and rollers are provided at intervals on the rear side of the bottom of the mobile frame 10, and supporting legs are provided on the front side to facilitate the movement and placement of the mobile frame 10. The fixed frame 20 is arranged on the mobile frame 10 and is arranged on one side of the nozzle of the valve 12 of the fire extinguisher body. The fixed frame 20 includes two horizontal bars 21 arranged vertically at intervals and two vertical bars 22 connecting the corresponding ends of the two horizontal bars 21. The vertical frame 30 is slidably arranged between the two horizontal bars 21, and the horizontal frame 40 is slidably arranged between the two vertical bars 22. The left and right sides of the vertical frame 30 are provided with first strip holes 31 arranged vertically for the horizontal frame 40 to pass through. A square area is formed between the horizontal frame 40 and the vertical frame 30, and in the square area, the mounting seat 50 is arranged in the square area, and the upper and lower ends of the mounting seat 50 are slidably arranged on the horizontal frame 4 0 on both sides, the left and right ends of the mounting seat 50 are slidably arranged on the left and right sides of the vertical frame 30, the first pushing mechanism 60 and the second pushing mechanism 70 are both arranged on the mobile frame 10, and a nozzle 13 whose nozzle direction is consistent with the nozzle direction of the fire extinguisher body valve 12 is arranged in the mounting seat 50, and the nozzle of the fire extinguisher body valve 12 is connected to the nozzle of the fire extinguisher body valve 12 at one end of the nozzle 13 adjacent to the nozzle of the fire extinguisher body valve 12 through a connecting pipe 14, and the first pushing mechanism 60 and the second pushing mechanism 70 push the horizontal frame 40 and the vertical frame 30 to slide, thereby driving the mounting seat 50 to move, and then changing the spraying position of the nozzle 13 to achieve a better fire extinguishing effect.

[0032] Specifically, first slide bars 51 are horizontally arranged on the left and right sides of the mounting seat 50, and the first slide bars 51 are slidably arranged in the first strip holes 31, so as to ensure the stability of the mounting seat 50 sliding up and down in the vertical frame 30. Horizontally arranged second strip holes 41 are opened on the upper and lower sides of the horizontal frame 40, and second slide bars 52 are vertically arranged on the upper and lower sides of the mounting seat 50, and the second slide bars 52 are slidably arranged in the second strip holes 41, so as to ensure the stability of the mounting seat 50 sliding left and right in the horizontal frame 40. The mounting seat 50 is square in shape as a whole, and its left and right side walls are in sliding contact with the inner wall of the vertical frame 30, and the upper and lower side walls are in sliding contact with the inner wall of the horizontal frame 40, so as to prevent the mounting seat 50 from rotating so as to cause the first slide bars 51 and the second slide bars 52 to be separated from the first strip holes 31 and the second strip holes 41.

[0033] When setting up, a third strip-shaped hole 23 arranged vertically is formed in the vertical rod 22. Third sliding rods 42 are horizontally arranged on the left and right sides of the horizontal frame 40, and the third sliding rods 42 are slidably arranged in the third strip-shaped hole 23, ensuring the stability of the up-and-down sliding of the horizontal frame 40 between the vertical rods 22. The first pushing assembly includes a first positioning frame 61, a first pushing rod 62, and a first adjusting plate 63. There are two first positioning frames 61, and the two first positioning frames 61 are horizontally arranged at intervals on one side of the moving frame 10. There is one first pushing rod 62, and the length direction thereof is the same as the nozzle direction of the nozzle 13 and is slidably arranged in the two first positioning frames 61, so that the first pushing rod 62 can stably slide in the first positioning frame 61. The first adjusting plate 63 is arranged at one end of the first pushing rod 62 close to the fixed frame 20. The plate surface of the first adjusting plate 63 is in a vertical state and is arranged in a staggered manner with the vertical rod 22. A first adjusting groove 64 is arranged along the length direction of the first adjusting plate 63. The end of the third sliding rod 42 on the right side of the horizontal frame 40 extends outward and is slidably arranged in the first adjusting groove 64. Pulling the first pushing rod 62 drives the first adjusting plate 63 to move back and forth. Since the third sliding rod 42 is restricted by the third strip-shaped hole 23 and can only slide up and down, when the first adjusting plate 63 moves back and forth, the third sliding rod 42 is always at the intersection of the third strip-shaped hole 23 and the first adjusting groove 64, thereby driving the horizontal frame 40 to slide up and down, and further driving the nozzle 13 to slide up and down. The first pushing rod 62 extends towards the rear side of the moving frame 10, enabling personnel to control the nozzle 13 at the rear side of the moving frame 10, reducing the danger of personnel extinguishing fires. A baffle is arranged at the end of the third sliding rod 42 on the right side of the horizontal frame 40. The plate surface of the baffle close to the third sliding rod 42 is in sliding contact with the first adjusting plate 63, restricting the first adjusting plate 63 and preventing the third sliding rod 42 from separating from the first adjusting groove 64, resulting in the inability to control the movement of the horizontal frame 40.

[0034] A first threaded hole 65 arranged vertically is formed in the first positioning frame 61 far from the fixed frame 20. A first threaded rod 66 is spirally arranged in the first threaded hole 65. The lower end of the first threaded rod 66 abuts against the first pushing rod 62. Turning the first threaded rod 66 enables the first threaded rod 66 to move up and down in the first threaded hole 65, making the lower end of the first threaded rod 66 abut against or separate from the first pushing rod 62, facilitating the fixation of the first pushing rod 62.

[0035] During specific setting, a fourth strip-shaped hole 24 arranged horizontally is formed in the cross bar 21. Fourth sliding rods 32 are vertically arranged on the upper and lower sides of the vertical frame 30. The fourth sliding rods 32 are slidably arranged in the fourth strip-shaped hole 24, ensuring the stability of the left-right sliding of the vertical frame 30 between the cross bars 21. The second pushing assembly includes a second positioning frame 71, a second pushing rod 72, and a second adjusting plate 73. There are two second positioning frames 71, which are horizontally and spaced apart on the side of the moving frame 10 away from the first positioning frame 61. There is one second pushing rod 72, whose length direction is the same as the nozzle direction of the nozzle 13 and is slidably arranged in the two second positioning frames 71, enabling the second pushing rod 72 to stably slide in the second positioning frame 71. The second adjusting plate 73 is arranged at one end of the first pushing rod 62 close to the fixed frame 20. The plate surface of the second adjusting plate 73 is in a horizontal state and is arranged in a staggered manner with the cross bar 21. A second adjusting groove 74 is arranged along the length direction of the second adjusting plate 73. The end of the fourth sliding rod 32 on the lower side of the vertical frame 30 extends outward and is slidably arranged in the second adjusting groove 74. Pulling the second pushing rod 72 drives the second adjusting plate 73 to move back and forth. Since the fourth sliding rod 32 is restricted by the fourth strip-shaped hole 24 and can only slide left and right, when the second adjusting plate 73 moves back and forth, the fourth sliding rod 32 is always at the intersection of the fourth strip-shaped hole 24 and the second adjusting groove 74, thereby driving the vertical frame 30 to slide left and right, and further driving the nozzle 13 to move left and right. The second pushing rod 72 extends towards the rear side of the moving frame 10, enabling personnel to control the nozzle 13 at the rear side of the moving frame 10, reducing the danger of personnel extinguishing fire. A baffle is also arranged at the end of the fourth sliding rod 32 on the lower side of the vertical frame 30. The plate surface of the baffle close to the fourth sliding rod 32 is in sliding contact with the second adjusting plate 73, restricting the second adjusting plate 73 to prevent the fourth sliding rod 32 from separating from the second adjusting groove 74, resulting in the inability to control the movement of the vertical frame 30.

[0036] A second threaded hole arranged vertically is formed in the second positioning frame 71 away from the fixed frame 20. A second threaded rod 75 is spirally arranged in the second threaded hole. The lower end of the second threaded rod 75 abuts against the second pushing rod 72. Turning the second threaded rod 75 enables the second threaded rod 75 to move up and down in the second threaded hole, making the lower end of the second threaded rod 75 abut against or separate from the second pushing rod 72, facilitating the fixing of the second pushing rod 72.

[0037] In this embodiment, the working principle of a dry powder fire extinguisher is as follows: After discovering a fire in an area, the fire extinguisher body 11 is moved to the fire area through the moving frame 10, and then the valve of the fire extinguisher body 11 is opened, so that the dry powder in the fire extinguisher body 11 reaches the nozzle 13 through the connecting pipe 14 and is ejected. Pull the first push rod 62 to drive the first adjusting plate 63 to move back and forth, drive the horizontal frame 40 to slide up and down, and then drive the nozzle 13 to move up and down; pull the second push rod 72 to drive the second adjusting plate 73 to move back and forth, drive the vertical frame 30 to slide left and right, and then drive the nozzle 13 to move left and right. The first push rod 62 and the second push rod 72 extend to the rear side of the moving frame 10, so that personnel can control the spraying position of the nozzle 13 at the rear side of the moving frame 10, reducing the danger of personnel extinguishing the fire while achieving a better fire extinguishing effect.

[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
