[0040] like Figures 1 to 6As shown, the present invention discloses a fixed fire-fighting jet cannon, comprising a fixed cylinder 1 and a jet cannon 12; a pair of symmetrically distributed connecting pipes 11 are fixedly connected to both sides of the top end of the fixed cylinder 1; each connecting pipe 11 includes an arc-shaped pipe 15 and a horizontal pipe 16; one end of the arc-shaped pipe 15 is fixedly connected to the fixed cylinder 1, and the other end is fixedly connected to the end of the horizontal pipe 16; a jet cannon 12 is provided between the pair of horizontal pipes 16; a pair of symmetrically distributed rotating pipes 13 are fixedly connected to the outer wall of the jet cannon 12; the ends of the pair of rotating pipes 13 are respectively rotatably connected to the ends of the horizontal pipes 16; an annular disc 17 is fixedly connected to the outer wall of the horizontal pipe 16; a U-shaped handle 14 is fixedly connected to the pair of rotating pipes 13; the... The U-shaped handle 14 limits the spray angle of the spray tube 12 through the positioning component. In the prior art, when operating a fire monitor, the spray angle needs to be adjusted manually. However, because there is a certain reaction force when the water jet is sprayed from the cannon, firefighters may lose their grip, leading to safety accidents and affecting firefighting efficiency. Therefore, in this invention, when in operation, the operator holds the U-shaped handle 14 to rotate the spray tube 12 and the rotating pipe 13 on the horizontal pipe 16, thereby adjusting the spray angle. After the spray angle is adjusted, the positioning component limits the angle, reducing the reaction force of the sprayed water on the operator's hand. The positioning component bears the reaction force, and the operator only plays the role of adjusting the angle.
[0041] The positioning component includes a circular groove 2; a set of circular grooves 2 are formed on the annular disk 17, and the set of circular grooves 2 are distributed in a semi-circular manner; a first cavity 21 is formed at both ends of the U-shaped handle 14; a sliding block 22 is slidably connected in the first cavity 21, and the sliding block 22 is fixed to the side wall of the first cavity 21 by a spring; a locking post 23 is fixed to the end of the sliding block 22, and the locking post 23 extends out of the U-shaped handle 14; the sliding block 22 is pushed by a pushing unit;
[0042] The pushing unit includes a right-angled trapezoidal through slot 24; the sliding block 22 has a right-angled trapezoidal through slot 24; the U-shaped handle 14 has first sliding grooves 25 on both side walls; a pull plate 26 is provided in the first cavity 21, the end of the pull plate 26 passes through the right-angled trapezoidal through slot 24 and extends into the first sliding groove 25, and one end of the pull plate 26 is fixed to the side wall of the first sliding groove 25 by a spring; a push plate 27 is fixed to the side wall of the pull plate 26 near the inclined surface of the right-angled trapezoidal through slot 24; a cylinder 28 is slidably connected between a pair of first sliding grooves 25, and both ends of the cylinder 28 are fixed to the pull plate 26 respectively;
[0043] The locking post 23 is a cylindrical body 28, and an arc-shaped surface 29 is provided on the end of the locking post 23;
[0044] The length of the short opening of the right-angled trapezoidal through slot 24 is less than the length of the push plate 27;
[0045] During operation, when adjusting the spray angle, the operator opens their hand, grasps the cylinder 28, and retracts the cylinder 28 and the pair of push plates 27. At this time, the push plates 27 push the inclined surface of the right-angled trapezoidal channel 24, causing the sliding block 22 to move, thereby disengaging the locking column 23 from the circular groove 2. Fang Baini then adjusts the spray angle. After the adjustment is completed, the operator releases the cylinder 28, allowing the locking column 23 to re-enter the circular groove 2. During the spraying process, when adjusting the angle, the operator needs to withstand a certain force after the locking column 23 disengages from the circular groove 2. However, this is not a continuous force; it is only a force required for adjustment and does not affect the overall operation. Even if the operator loses control during adjustment, the locking column 23 will re-enter the adjacent circular groove 2, preventing injury to the operator.
[0046] The fixed cylinder 1 includes a bottom cylinder 3 and a rotating cylinder 31; the rotating cylinder 31 is rotatably connected to the bottom cylinder 3; the rotating cylinder 31 rotates through a rotating unit; the connecting pipe 11 is fixedly connected to the outer wall of the rotating cylinder 31.
[0047] The rotating unit includes a first gear 32 and a ring gear 33; a ring rack is fixedly connected to the outer wall of the rotating cylinder 31; a servo motor 34 is fixedly connected to the mounting plate at the bottom end of the bottom cylinder 3; the output end of the servo motor 34 is provided with a first gear 32; the first gear 32 and the ring gear 33 mesh with each other.
[0048] The inner diameter of the first gear 32 is smaller than the inner diameter of the ring gear 33;
[0049] A pair of shields 35 symmetrically distributed about the ring gear 33 are fixedly connected to the rotating cylinder 31; a shield 36 is fixedly connected to the mounting plate at the bottom end of the bottom cylinder 3, and the servo motor 34 and the first gear 32 are located inside the shield 36.
[0050] A button is provided at the end of the U-shaped handle 14;
[0051] During operation, the forward and reverse rotation of the servo motor 34 is adjusted by the button. The servo motor 34 also has a braking mechanism, which will not be described in the existing technology. After the angle is adjusted by the operator, the forward and reverse rotation of the servo motor 34 is controlled by the button. Then, the axial angle of the spray is adjusted by setting the first gear 32 and the ring gear 33, which further improves the spray range of the spray cylinder 12.
[0052] Working principle: When adjusting the spray angle, the operator opens their hand, grasps the cylinder 28, and retracts the cylinder 28 and the pair of push plates 27. At this time, the push plates 27 push the inclined surface of the right-angled trapezoidal groove 24, causing the sliding block 22 to move, thereby disengaging the locking post 23 from the groove 2. Fang Baini then adjusts the spray angle. After adjustment, the operator releases the cylinder 28, allowing the locking post 23 to re-enter the groove 2. During the spraying process, when adjusting the angle, the operator needs to withstand a certain force after the locking post 23 disengages from the groove 2, but this force is not continuous. The force applied is only required during the adjustment process and does not affect the overall operation. Even if the hand slips during adjustment, the locking post 23 will lock into the adjacent circular groove 2, preventing injury to personnel. The forward and reverse rotation of the servo motor 34 is adjusted by the button. The servo motor 34 has a braking mechanism, which will not be described in the existing technology. After the angle is adjusted, the forward and reverse rotation of the servo motor 34 is controlled by the button. Then, through the setting of the first gear 32 and the ring gear 33, the axial angle of the spray is adjusted to further increase the spray range of the spray cylinder 12.
