DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] like Figure 1-5 As shown, the utility model provides a fire-fighting water monitor water outlet switching structure, including a connecting pipe 1, a connected gun head pipe 2 is fixedly installed on the upper end of the connecting pipe 1, a switching mechanism 3 is sleeved on the outer side of the top of the gun head pipe 2, a water diverter 4 is installed inside the top of the gun head pipe 2, a connecting rod 5 is threadedly connected to the lower end of the water diverter 4, and a plurality of groups of fixedly installed water dividers 6 are equidistantly distributed outside the lower end of the connecting rod 5, a support seat 7 is fixedly connected to the lower side of the inner cavity of the gun head pipe 2, an arc-shaped notch 8 is opened on the inner wall of the upper end of the support seat 7, and a swirl cylinder 9 is fixedly connected to the lower side of the support seat 7.

[0025] A conical slot is provided in the middle of the top of the gun head tube 2, and the water diverter 4 is movably installed with the conical slot, and a gap is left between the water diverter 4 and the conical slot.

[0026] The water divider 6 is a water divider blade, and a flow divider cavity is left between the water divider blades.

[0027] The arc-shaped notch 8 is a tapered notch.

[0028] When the water flows through the diversion cavity between the water dividers 6, the equidistantly distributed water dividers 6 can make the water flow enter a relatively static state, which can effectively offset the centrifugal force generated when the water flow rotates and moves, thereby improving the condensation effect of the water column when it is sprayed out, reducing the friction coefficient between the water column and the air, and the arc-shaped slot 8 is tapered, so as to reduce the turbulence of the water flow. The swirl tube 9 is set to improve the concentration of the water flow when it is sprayed out.

[0029] like Figure 3-5As shown, the switching mechanism 3 includes a base plate 31, the bottom end of the base plate 31 is symmetrically fixedly connected to the outer walls of both sides of the gun head tube 2, an electric push rod 32 is fixedly installed on the upper end of the base plate 31, and the top of the output rod of the electric push rod 32 is fixedly connected to the top plate 33, and the top outer wall of the gun head tube 2 is provided with an annular groove 34, and the outer sliding sleeve of the annular groove 34 is connected with a switching water outlet cylinder 35, and a plurality of groups of equidistantly distributed guide strips 36 are fixedly installed on the top of the switching water outlet cylinder 35, and the inner wall of the switching water outlet cylinder 35 is symmetrically provided with limiting grooves 37, and the upper side of the outer wall of the annular groove 34 is symmetrically fixedly installed with limiting blocks 38.

[0030] The top of the water outlet cylinder 35 is provided with an inclined surface, and the inclined surface is inclined inward from top to bottom. Meanwhile, a guide bar 36 is arranged on the inclined surface, and the inclination direction of the guide bar 36 is consistent with the inclination direction of the inclined surface.

[0031] The bottom end of the top plate 33 is fixedly connected to the outer wall of the water outlet switching cylinder 35 .

[0032] The limiting block 38 matches the limiting groove 37 and can slide in a limited manner.

[0033] When the water outlet cylinder 35 is switched to slide up and down on the annular groove 34, the limit block 38 will slide synchronously in the limit groove 37, thereby improving the stability of the movement of the water outlet cylinder 35. The inclined surface and the equally distributed guide strips 36 are helpful in guiding the water flow, making the spraying distribution more uniform and the effect better.

[0034] The working principle of the fire monitor water outlet switching structure is described in detail below.

[0035] like Figure 1-5 As shown, when the fire monitor water outlet switching structure is in use, the connecting pipe 1 at the lower end of the gun head pipe 2 can be connected to the connecting pipe 1 of the fire monitor first, so as to facilitate the use of the gun head pipe 2. When switching is required, the electric push rod 32 can be started, so that the electric push rod 32 pushes the top plate 33 upward, so that the top plate 33 drives the switching water outlet cylinder 35 to move synchronously, and the switching water outlet cylinder 35 slides upward on the annular groove 34, so that the guide strip 36 at the top of the switching water outlet cylinder 35 and the water diversion head 4 at the top of the gun head pipe 2 can be raised by a section, and the water flow can flow into the gun head pipe 2 at this time. The water flow in the gun head tube 2 passes through the conical groove on the top and is sprayed out. At this time, the water flow is sprayed out in a columnar shape. When the output rod of the electric push rod 32 moves downward, the top plate 33 can drive the switching water outlet cylinder 35 to move downward synchronously, so that the top of the switching water outlet cylinder 35 can be aligned with the top of the gun head tube 2, and the water diverter 4 can be exposed. At this time, when the water flow is sprayed out from the conical groove again, it will be sprayed out in the shape of water mist under the guidance of the inclined surface at the top of the water outlet cylinder and the guide strip 36, thereby completing the switching of the water flow, thereby improving the practicability of the device.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
