Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and in particular relates to a fire-fighting equipment booster jet. Background Technology

[0002] A fire sprinkler is a mechanical device that uses high-pressure fluid to draw in low-pressure fluid and transfers energy through the collision of fluids. It has advantages such as low operating costs and simple structure. Fire sprinklers require water jets, but currently available water jets can only spray a single fluid and cannot mix multiple fluids. Since fires have diverse causes, they require not only the sprayed fluid but also other extinguishing agents, resulting in poor extinguishing effectiveness and limited functionality. A search revealed patent application number 201620410219.3, which discloses a fire-fighting equipment booster sprinkler, comprising a graphite composite wall and a nozzle. A suction nozzle seat and studs are fixedly installed on the upper surface of the graphite composite wall. A suction chamber is installed above the suction nozzle seat, and a liquid ring vacuum pump is installed on its bottom surface. A U-tube pressure gauge is installed at the bottom of the liquid ring vacuum pump. The interior of the graphite composite wall is divided into an inlet channel and a return channel by a jet valve, and spray interfaces are fixedly connected to the inlets of both the inlet and return channels via rotating shafts.

[0003] However, in actual use, the applicant found that during firefighting operations, due to the lack of auxiliary support structure for the sprayer, personnel need to manually lift the entire sprayer and carry out firefighting operations for a long time. At the same time, because the sprayer has a certain weight, it will put a great physical load on firefighters. In view of this, we propose a firefighting equipment raising sprayer. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a fire-fighting equipment booster sprayer, comprising a support base, which is sleeved and fixed on a rotating shaft. Support legs are symmetrically and movably sleeved at both ends of the rotating shaft via bearings. A turntable is rotatably connected to the top of the support base via bearings. A cylindrical tube is fixedly connected to the top of the turntable. A stepped tube is fixedly connected to the front end of the cylindrical tube, and the stepped tube communicates with the interior of the cylindrical tube. Liquid-guiding branch pipes are arranged in a circular array on the outer wall of the rear end of the cylindrical tube. A seat body is sleeved and fixed to the outer wall of the cylindrical tube outside the liquid-guiding branch pipes. A connecting pipe is fixedly connected to the outer end of each liquid-guiding branch pipe. The end of the connecting pipe away from the liquid-guiding branch pipe extends to the outside of the seat body and is sleeved and fixedly fitted with a hand valve. A mixing shaft is rotatably connected to the interior of the cylindrical tube via bearings. An impeller is sleeved and fixed to the mixing shaft near the inner end of the liquid-guiding branch pipe. A mixing blade is fixedly arranged on the outer wall of the mixing shaft in front of the impeller.

[0006] Preferably, the cylindrical tube has a mixing chamber inside, and the mixing shaft is located in the mixing chamber.

[0007] Preferably, a converging cavity is provided in the cylindrical tube on the front side of the mixing chamber, and the converging cavity is in communication with the interior of the stepped tube.

[0008] Preferably, the mixing chamber is connected to the converging chamber through a through groove inside the cylindrical tube.

[0009] Preferably, a plurality of mixing blades are uniformly arranged along the axial direction of the mixing shaft.

[0010] Preferably, a handrail is fixedly connected to the outer wall of the turntable.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses a fire-fighting equipment height-adjusting sprayer. Through its support base, rotating shaft, support legs, turntable, and handrail, it allows for smooth adjustment of the direction of the cylindrical and stepped cylinders while assisting firefighters in supporting them. This eliminates the need for firefighters to manually lift the sprayer for extended periods, effectively reducing their physical burden. When the extinguishing agent enters the mixing chamber through the liquid guide pipe, it drives the impeller to rotate. The impeller, in turn, drives the mixing shaft and mixing blades to rotate, thoroughly mixing the various extinguishing agents entering the mixing chamber. After mixing, the extinguishing agent enters the converging chamber through the channel. Due to the channel's interception effect, the extinguishing agent is automatically pressurized. Furthermore, after entering the stepped cylinder, the space within the stepped cylinder gradually decreases towards the nozzle, resulting in secondary pressurization of the extinguishing agent. This allows for the more thoroughly mixed extinguishing agent to be sprayed out at higher pressure, leading to better fire-fighting effectiveness. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A fire-fighting equipment booster sprayer includes a support base 1, which is sleeved and fixed on a rotating shaft 2. Support legs 3 are symmetrically and movably sleeved at both ends of the rotating shaft 2 via bearings. A turntable 4 is rotatably connected to the top of the support base 1 via bearings. A handrail 8 is fixedly connected to the outer wall of the turntable 4. A cylindrical tube 5 is fixedly connected to the top of the turntable 4. A stepped tube 6 is fixedly connected to the front end of the cylindrical tube 5, and the stepped tube 6 communicates with the interior of the cylindrical tube 5. Through the support base 1, rotating shaft 2, support legs 3, turntable 4, and handrail 8, the direction of the cylindrical tube 5 and the stepped tube 6 can be smoothly adjusted, while also assisting firefighters in providing auxiliary support for the cylindrical tube 5 and the stepped tube 6. This eliminates the need for firefighters to manually lift the sprayer for extended periods, effectively reducing the physical load on firefighters. Liquid-guiding branch pipes 51 are arranged in a ring array on the outer wall of the rear end of the cylindrical tube 5. A base 7 is fixedly fitted onto the outer wall of the cylindrical tube 5 outside the liquid-guiding branch pipe 51. A connecting pipe 9 is fixedly connected to the outer end of the liquid-guiding branch pipe 51. The end of the connecting pipe 9 away from the liquid-guiding branch pipe 51 extends to the outside of the base 7 and is fitted with a hand valve 10. During fire fighting, the booster sprayer can be moved to a suitable position and placed stably on the ground by the support leg 3 to stably support the cylindrical tube 5 and the stepped tube 6. Then, the personnel can connect the fire extinguishing agent required for fire fighting to the end of the connecting pipe 9 under the base 7 and manually open the hand valve 10 on the corresponding connecting pipe 9. At this time, the personnel can hold the handle 8 to drive the cylindrical tube 5 and the stepped tube 6 to rotate around the rotating shaft 2 to realize the longitudinal angle adjustment of the sprayer. The personnel can also realize the lateral angle adjustment of the sprayer by rotating the turntable 4, thereby enabling fire fighting operations.

[0022] Inside the cylindrical tube 5, a mixing shaft 12 is rotatably connected via bearings. An impeller 11 is sleeved and fixed on the mixing shaft 12 near the inner end of the liquid guide branch pipe 51. Mixing blades 121 are fixedly installed on the outer wall of the mixing shaft 12 in front of the impeller 11. Several mixing blades 121 are evenly arranged along the axial direction of the mixing shaft 12. A mixing chamber 52 is provided inside the cylindrical tube 5, and the mixing shaft 12 is located in the mixing chamber 52. A converging chamber 54 is provided in the cylindrical tube 5 in front of the mixing chamber 52. The converging chamber 54 and the inner wall of the stepped tube 6 are connected. The mixing chamber 52 is connected to the converging chamber 54 through a through-slot 53 inside the cylindrical tube 5. When the extinguishing agent enters the mixing chamber 52 through the liquid guide branch pipe 51, it drives the impeller 11 to rotate. The impeller 11 drives the mixing shaft 12 and the mixing blades 121 to rotate. The mixing blades 121 fully mix the various extinguishing agents entering the mixing chamber 52. When the mixed extinguishing agent enters the converging chamber 54 through the through-slot 53, the through-slot 53 automatically pressurizes the extinguishing agent. After the extinguishing agent inside the stepped cylinder 6 enters the cylinder 54, the space inside the stepped cylinder 6 gradually decreases towards the nozzle, which can repressurize the extinguishing agent. This allows the more thoroughly mixed extinguishing agent to be sprayed out at a higher pressure, resulting in better fire-fighting effect. The required extinguishing agent is transported to the liquid guide branch pipe 51 through the connecting pipe 9, and then introduced into the mixing chamber 52 inside the cylindrical cylinder 5 through the liquid guide branch pipe 51. This drives the impeller 11 to rotate, and the rotation of the impeller 11 drives the mixing shaft 12 and the mixing blades 121 to rotate together, thereby extinguishing the fire entering the mixing chamber. The extinguishing agent inside cavity 52 is mixed, and the mixed extinguishing agent can enter the converging cavity 54 through the channel 53, and then enter the stepped cylinder 6 through the converging cavity 54. It is then sprayed out at high pressure from the nozzle at the front end of the stepped cylinder 6. During this process, due to the interception effect of the channel 53, the extinguishing agent is automatically pressurized. After the extinguishing agent inside the converging cavity 54 enters the stepped cylinder 6, the space inside the stepped cylinder 6 gradually decreases towards the nozzle opening, which can further pressurize the extinguishing agent, allowing the more thoroughly mixed extinguishing agent to be sprayed out at a higher pressure.

[0023] Working Principle: During firefighting, the booster sprayer can be moved to a suitable position and placed stably on the ground using the support legs 3, providing stable support for the cylindrical cylinder 5 and the stepped cylinder 6. Then, personnel can connect the required extinguishing agent to the end of the connecting pipe 9 below the base 7 and manually open the hand valve 10 on the corresponding connecting pipe 9. The required extinguishing agent is then transported through the connecting pipe 9 to the liquid guide branch pipe 51, and then introduced into the mixing chamber 52 inside the cylindrical cylinder 5. This drives the impeller 11 to rotate, which in turn drives the mixing shaft 12 along with the mixing blades 121, thus mixing the extinguishing agent entering the mixing chamber 52. The mixed extinguishing agent... The extinguishing agent can enter the converging chamber 54 through the channel 53, and then enter the stepped cylinder 6 through the converging chamber 54. Finally, it is ejected at high pressure from the nozzle at the front end of the stepped cylinder 6. During this process, due to the interception effect of the channel 53, the extinguishing agent will be automatically pressurized. After the extinguishing agent inside the converging chamber 54 enters the stepped cylinder 6, the space inside the stepped cylinder 6 gradually decreases towards the nozzle, which can further pressurize the extinguishing agent, allowing the more thoroughly mixed extinguishing agent to be ejected at a higher pressure. At this time, personnel can hold the handle 8 to drive the cylindrical cylinder 5 and the stepped cylinder 6 to rotate around the rotating shaft 2, thereby adjusting the longitudinal angle of the sprayer. They can also adjust the lateral angle of the sprayer by rotating the turntable 4, thus enabling fire fighting operations.
