The invention aims to solve the problems and provides a hydrodynamic fire-fighting robot.

In order to achieve the purpose, the invention adopts the following technical scheme:

the device comprises a framework, wherein hemispheroids are sleeved on the upper side and the lower side of the framework, and the inner surfaces of the two hemispheroids are rotatably connected with the framework;

fixedly connected with inlet tube and shunt tubes on the skeleton, and the two constitutes the tee bend structure, the both ends of shunt tubes are all rotated and are connected with the sleeve, telescopic equidistance intercommunication has a plurality of injection pipes on circumference, the injection pipe is kept away from telescopic one end and is passed the hemisphere and communicate with external space.

Optionally, the upper end and the lower end of the framework are fixedly connected with fixing frames adopting conical structures, the top ends of the fixing frames are in interference fit with first bearings, and the fixing frames are rotatably connected with the sleeve through the first bearings.

Optionally, the skeleton adopts cylindrical structure, and the equal interference fit in upper and lower both sides of skeleton has the second bearing, the skeleton passes through second bearing and hemisphere fixed connection.

Optionally, one side of the injection pipe close to the outlet is fixedly connected with a plurality of baffle plates inclined to the outlet, and a through hole is formed between every two adjacent baffle plates.

Compared with the prior art, the invention has the following advantages:

according to the invention, the upper and lower sides of the framework are respectively provided with the two hemispheroids, when liquid in the injection pipe is injected, a reaction force is generated on the hemispheroids, the hemispheroids are connected with the framework rotating wheel through the second bearing, the reaction force continuously pushes the hemispheroids to rotate, the hemispheroids at the bottom rotate and continuously move on the ground to extinguish fire, and the hemispheroids at the top continuously rotate and inject, so that high-altitude fire fighting is realized, fire sources at high and low positions are extinguished without dead angles of 360 degrees, and the robot body forms a spherical shape due to the hemispheroids at the upper and lower sides, so that the robot body can conveniently roll into deep fire sources, and is particularly suitable for complex terrains at the positions burnt by flames.

In the second embodiment of the invention, the robot is more energy-saving, according to the "bernoulli effect": the faster the flow rate, the lower the pressure. Therefore, when the liquid in the jet pipe passes through quickly, negative pressure can be formed in the jet pipe, so that the outside air enters the jet pipe through the through hole, the original pure liquid jet is changed into gas-liquid two-phase jet, and the water resource can be saved. And the setting of separation blade for liquid flows through along the inclined plane of separation blade and increases the velocity of flow of this department, increases the performance of bleeding, and on the other hand can be with the liquid disorder in the injection pipe, makes the abundant mixture of gas and the liquid in the injection pipe.

The invention has the outstanding characteristics that energy with explosion hidden danger such as batteries or fuel oil is not needed as power, the invention is safe and reliable, meanwhile, the surface of the sphere is similar to a sphere, the sphere can go deep into a complex environment, and simultaneously, the invention saves energy and has wide fire extinguishing range.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example one

Referring to fig. 1 to 3, hemispheroids 1 are respectively sleeved on the upper side and the lower side of a framework 2, and the inner surfaces of the two hemispheroids 1 are rotatably connected with the framework 2.

Skeleton 2 adopts cylinder type structure, and the equal interference fit in the upper and lower both sides of skeleton 2 has second bearing 8, and skeleton 2 passes through second bearing 8 and hemisphere 1 fixed connection, and the effect of second bearing 8 lies in for hemisphere 1 rotates with skeleton 2 relatively, so sets up, can make hemisphere 1 of its upside and downside independently rotate, has avoided skeleton 2 to rotate the pipeline winding that drives and inlet tube 3 intercommunication greatly.

In the preferred embodiment of the invention, the hemisphere 1 and the framework 2 are made of metal materials.

Fixedly connected with inlet tube 3 and shunt tubes 7 on the skeleton 2, and the two constitutes the tee bend structure, and the both ends of shunt tubes 7 are all rotated and are connected with sleeve 5, and the equidistant intercommunication has a plurality of injection pipes 9 on sleeve 5's the circumference, and the one end that sleeve 5 was kept away from to injection pipe 9 passes hemisphere 1 and communicates with external space.

The upper end and the lower end of the framework 2 are fixedly connected with a fixing frame 4 adopting a conical structure, the top end of the fixing frame 4 is in interference fit with a first bearing 6, and the fixing frame 4 is rotatably connected with the sleeve 5 through the first bearing 6. The first bearing 6 has the effect of rotating the holder 4 relative to the sleeve 5.

When the fire fighting water source valve is used, the water inlet pipe 3 of the water power robot can be communicated with a fire fighting water source, the water power robot is thrown into a fire catching place, and is particularly suitable for indoor use, the fire fighting water source valve is opened, liquid is sent into the hemispheroids 1 on the upper side and the lower side through the water source in the water inlet pipe 3 through the shunt pipe 7 and is shunted into the plurality of injection pipes 9 under the obstruction of the sleeve 5 and is sprayed out from the openings of the injection pipes 9, when the liquid in the injection pipes 9 is sprayed out, a reaction force is generated on the hemispheroids 1, as the hemispheroids 1 are connected with the rotating wheel of the framework 1 through the second bearing 8, the reaction force continuously pushes the hemispheroids 1 to rotate, the hemispheroids 1 on the bottom rotate and continuously move on the ground to extinguish fire, the hemispheroids 1 on the top continuously rotate and are sprayed, so that fire fighting at high places and low places can be carried out with no dead, and because the hemispheroids 1 on the upper side and the lower side enable the robot body to form a sphere, the robot body is convenient to roll into a deep fire source, and is particularly suitable for complex terrains at flame burning positions.

Example two

Referring to fig. 3 and 4, the present embodiment further provides the following on the basis of the first embodiment:

one side of the injection pipe 9 close to the outlet is fixedly connected with a plurality of baffle plates 10 which are inclined to the outlet, and a through hole 11 is arranged between two adjacent baffle plates 10.

This embodiment is more energy efficient than the first embodiment, according to the "bernoulli effect": the faster the flow rate, the lower the pressure. Therefore, when the liquid in the injection pipe 9 passes through rapidly, negative pressure can be formed in the injection pipe 9, and therefore outside air enters the injection pipe 9 through the through hole 11, so that the original pure liquid injection is changed into gas-liquid two-phase injection, and water resources can be saved. The baffle plate 10 is arranged, so that the liquid flows along the inclined surface of the baffle plate 10 to increase the flow speed at the position and increase the air suction performance, and on the other hand, the liquid in the injection pipe 9 can be disturbed, so that the gas and the liquid in the injection pipe 9 are fully mixed.
