[0025] As Figure 1 , Figure 2 and Figure 3 Indicated, in the working process of fire monitor head 2, servo motor 41 in drive assembly 4 drives second belt pulley 44 to rotate on the outer wall of fire monitor head 2, when second belt pulley 44 rotates, it drives water curtain assembly 6 on its outer wall to rotate, so that water curtain assembly 6 rotates around fire monitor head 2, and the water of multiple nozzles 65 included in water curtain assembly 6 is formed water curtain and is sprayed to fire monitor head 2, when the surface of fire monitor head 2 is high temperature, the water of spraying is cooled to its surface, and high temperature makes the water on its surface evaporate and absorb heat, to reach the means of cooling, avoid fire monitor head 2 in high temperature state and carry out self-protection.

[0026] Combination Figure 2 and Figure 3, the connection assembly 3 is used to load the driving assembly 4, and keep the driving assembly 4 synchronous with the rotation of the fire monitor head 2 as the electric telescopic rod 7 pushes the driving assembly 4 to move, the connection assembly 3 comprises a sleeve ring 31 sleeved on the outer wall of the mounting frame 8, the sleeve ring 31 rotates on the outer wall of the mounting frame 8 and has the ability to rotate, one end of a supporting rod 32 is installed on the outer wall of the sleeve ring 31, the supporting rod 32 is a medium connected between the motor base 34 and the sleeve ring 31, the other end of the supporting rod 32 is installed with the motor base 34, the inside of the motor base 34 is loaded with the servo motor 41, and the outer wall of the motor base 34 is installed with the first connecting rod 33, the other end of the first connecting rod 33 is connected with the electric telescopic rod 7, so that when the electric telescopic rod 7 is controlled to stretch or retract to rotate the fire monitor head 2, power is transmitted to the sleeve ring 31, so that the sleeve ring 31 rotates on the outer wall of the mounting frame 8.

[0027] According to the state in Figure 3 , when the electric telescopic rod 7 is stretched or retracted, the motor base 34 is pushed to move through the first connecting rod 33, and the servo motor 41 in the motor base 31 is also driven to rotate, when the motor base 34 rotates, the sleeve ring 31 is pushed to rotate on the outer wall of the mounting frame 8 through the supporting rod 32, and the motor base 34 drives the servo motor 41 in the driving assembly 4 to keep consistent with the rotation range of the fire monitor head 2.

[0028] As shown in Figure 2 , Figure 3 , the driving assembly 4 is used to provide power for the rotation of the water curtain assembly 6, the driving assembly 4 comprises the servo motor 41 and a second belt pulley 44, the servo motor 41 can rotate in forward and reverse directions, so as to avoid winding caused by the length of the water guide pipe 62 being insufficient after rotating in the same direction, however, the alternating rotation feature can meet the length of the water guide pipe 62 being sufficient, so that the first belt pulley 42 rotates, and the second belt pulley 44 can be driven through the belt 43, the servo motor 41 is installed in the inside of the motor base 34, the second belt pulley 44 is installed on the outer wall of the fire monitor head 2 through the mounting assembly 9, the second belt pulley 44 drives the water curtain assembly 6 to rotate on the outer wall of the fire monitor head 2 when rotating, the output end of the servo motor 41 is installed with the first belt pulley 42, and the first belt pulley 42 and the second belt pulley 44 are connected through the belt 43.

[0029] As can be seen from Figure 2 , when the servo motor 41 works, and the servo motor 41 can rotate in forward and reverse directions, it can periodically drive the first belt pulley 42 to rotate, the first belt pulley 42 transmits power to the second belt pulley 44 through the transmission of the belt 43, drives the second belt pulley 44 to rotate on the outer wall of the fire monitor head 2, and drives the water curtain assembly 6 to rotate around the fire monitor head 2 when the second belt pulley 44 rotates, the driving assembly 4 provides power for the rotation of the water curtain assembly 6 around the fire monitor head 2, so that the water curtain assembly 6 can comprehensively cool the outer surface of the fire monitor head 2.

[0030] As Figure 2 shown, in order to spray water on the surface of the fire gun head 2 to cool down, the water curtain assembly 6 is used, which includes a mounting lever 61 and a water guide pipe 62. The lever 61 is a medium for connecting the mounting plate 63 and the second belt pulley 44. The water guide pipe 62 transmits the water from the fire gun 1 to cool down the surface of the fire gun head 2. One end of the water guide pipe 62 is connected with the fire gun head 2, and the other end of the mounting lever 61 is installed on the outer wall of the second belt pulley 44. The other end of the mounting lever 61 is integrally formed with the mounting plate 63. The mounting plate 63 is arranged with nozzles 65. The nozzles 65 are longitudinally arranged and can cover the surface of the fire gun head 2. The sprayed water is sprayed to the surface of the fire gun head 2 through the nozzles 65 to cool down. The nozzles 65 are connected with the other end of the water guide pipe 62 through the branch pipe 64.

[0031] The water guide pipe 62 transmits the water from the fire gun body 1 to the nozzles 65 when the fire gun is working. The nozzles 65 spray water to the surface of the water guide pipe 62 to cool down. When the second belt pulley 44 rotates, the mounting plate 63 is driven to rotate by the lever 61. The nozzles 65 on the surface of the mounting plate 63 are driven to rotate. The nozzles 65 spray water to cool down the surface of the fire gun head 2.

[0032] In order to avoid the water sprayed by the nozzles 65 from soaking the servo motor 41, the upper end surface of the servo motor 41 is provided with a water blocking assembly 5. The water blocking assembly 5 blocks the surface of the servo motor 41 to prevent water from entering the servo motor 41. The water blocking assembly 5 includes a water blocking bucket 51. When the sprayed water falls, it is blocked by the water blocking bucket 51. The water blocking bucket 51 is sleeved on the outer wall of the output end of the servo motor 41. The water blocking bucket 51 is movably connected with the outer wall of the servo motor 41 through a sealing bearing. The sealing bearing enables the output end of the servo motor 41 to penetrate the water blocking bucket 51 while having the ability to rotate. It also enables the gap sealing to prevent water leakage. The outer wall of the water blocking bucket 51 is provided with a second connecting rod 52. The second connecting rod 52 is a medium for connecting the water blocking bucket 51 and the servo motor 41 to support. The other end of the second connecting rod 52 is connected with the upper end surface of the servo motor 41. The outer wall of the water blocking bucket 51 is integrally formed with a water guide nozzle 53. The water guide nozzle 53 guides the water in the water blocking bucket 51 to flow out. The direction of the water flow avoids falling on the surface of the servo motor 41. The side wall of the water blocking bucket 51 is provided with a through hole 54. The belt 43 penetrates the water blocking bucket 51 through the through hole 54 to ensure the normal transmission of the belt 43.

[0033] When the residual cooling water sprayed by the nozzles 65 falls on the surface of the servo motor 41, it is blocked by the water blocking bucket 51. Due to the bucket-shaped feature of the water blocking bucket 51, the water is temporarily stored. Then the water in the interior is conducted and discharged by the water guide nozzle 53.

[0034] AsFigure 4 As shown, in order to ensure the rotational capability of the second pulley 44, an installation assembly 9 is used as a connecting structure and installed on the outer wall of the fire monitor head 2. The installation assembly 9 includes a rotating groove 92 and a rotating ring 91. The rotating ring 91 is installed on the outer wall of the fire monitor head, the rotating groove 92 is opened on the inner wall of the second pulley 44, and the rotating ring 91 is located inside the rotating groove 92.

[0035] When the second pulley 44 rotates, the rotating ring 91 rotates with the second pulley 44 inside the rotating groove 92, so that the second pulley 44 can rotate on the outer wall of the fire monitor head 2.

[0036] To prevent the second pulley 44 from slipping during transmission by the conveyor belt 43, the inner wall of the second pulley 44 is machined with a frosted texture. The frosted texture increases the friction of the inner wall of the second pulley 44, thereby preventing slippage.

[0037] like Figure 5 As shown, the conveyor belt 43 can be installed inside the opening 54, the top of the opening 54 is open, and it can be inserted from above the opening 54 for installation.

[0038] The working principle of this utility model is explained below with reference to a preferred embodiment: When the fire monitor head 2 is working, the servo motor 41 drives the first pulley 42 to rotate. The first pulley 42 transmits power to the second pulley 44 through the belt 43, causing the second pulley 44 to rotate on the outer wall of the fire monitor head 2. When the second pulley 44 rotates, the mounting plate 63 is driven to rotate through the crank 61. The mounting plate 63 drives the nozzles 65 on its surface to rotate. The nozzles 65 spray and cool the surface of the fire monitor head 2. When the fire monitor head 2 is pushed by the electric telescopic rod 7, the push connecting rod 33 drives the motor base 34 and the servo motor 41 to rotate synchronously with the fire monitor head 2.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
