Description

Technical Field

[0001] The utility model relates to the technical field of water cannons, in particular to a steering component for law enforcement water cannon operation. Background Technique

[0002] When the existing water cannon starts, the large-range turning it generates is likely to cause accidental injury to the user. For this reason, a steering component for law enforcement water cannon operation is needed. Therefore, an existing steering component for law enforcement water cannon operation has been continuously innovated and developed. It can be seen that the existing steering component for law enforcement water cannon operation basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the publication number CN208254315U discloses a steering component for law enforcement water cannon operation, including a marine law enforcement water cannon. A steering device for controlling its horizontal rotation is arranged between the base and the gun body; the gun body is arranged in a meandering shape, and a pitching device for controlling the angle of the gun head is arranged between the gun body and the gun head; the gun head includes a bent pipe, one end of the bent pipe is connected to the pitching device, and the other end is connected to the rectifying section; a steady flow acceleration section and a steady flow injection section are sequentially arranged at the right end of the rectifying section; an arc-shaped guide plate is arranged inside the bent pipe; a rectifying plate is arranged at the left end of the rectifying section, and a steady flow device is arranged at its right end; the steady flow acceleration section is arranged in a conical shape to increase the flow rate of the water cannon; the steady flow injection section is arranged in a conical shape, and the taper of which is smaller than that of the steady flow acceleration section; the structure of the utility model is simple and ingeniously designed, effectively eliminating a large amount of turbulent flow generated by passing through the bend of the gun body, making the turbulent intensity in the water column ejected by the water cannon the lowest. It not only increases the range of the water cannon, expands the striking range, but also optimizes the water column forming effect and strengthens the slapping force, with great popularization and application value. Through the conical steady flow injection section, a large amount of turbulent flow generated by passing through the bend of the gun body is effectively eliminated, making the turbulent intensity in the water column ejected by the water cannon the lowest. It not only increases the range of the water cannon, expands the striking range, but also optimizes the water column forming effect.

[0004] However, when the device is actually used, due to the large flow rate generated when the water cannon starts, while generating a large flow rate, its steering structure will inevitably turn automatically under the influence of water flow. At this time, when the staff does not make corresponding forces, it is easy to cause accidental injury to the staff. Therefore, a steering component for law enforcement water cannon operation is urgently needed to solve the above problems. Content of the Utility Model

[0028] Please refer to Figure 1 、 Figure 3 and Figure 7 ,a steering component for law enforcement water cannon operation: including a base 1, a connecting block 2 is rotatably connected to the inner wall of the base 1, a transport pipe 3 is fixedly connected to the top of the connecting block 2, one end of the transport pipe 3 is rotatably connected to a guiding pipe 4, a nozzle 5 is fixedly connected to one end of the guiding pipe 4, and grooves 10 are opened on both sides of the nozzle 5;

[0029] A limiting mechanism, including a movable groove 6, the movable groove 6 is opened on one side of the inner wall of the base 1, a slider 7 is slidably connected to the inner wall of the movable groove 6, a handwheel 8 is threadedly connected to the inner wall of the slider 7, a limiting groove 9 is opened at the bottom of one side of the connecting block 2, and one side of the handwheel 8 is movably connected to the inner wall of the limiting groove 9.

[0030] When using a steering component for law enforcement water cannon operation, first install the base 1 at the working location, then connect the water pipe to the inner wall of the base 1, inject water source into the base 1 through the water pipe, and then flow through the base 1 into the transport pipe 3 inside the connecting block 2. The water source is transported to the guiding pipe 4 through the transport of the transport pipe 3 and finally sprayed out through the nozzle 5 at one end of the guiding pipe 4. The spraying angle of the nozzle 5 can be adjusted by rotating the guiding pipe 4 inside the transport pipe 3, or can be adjusted by rotating the connecting block 2 inside the base 1. When it is necessary to adjust the maximum angle of the connecting block 2 left and right, first rotate the handwheel 8 to take it out of the slider 7, then push the slider 7 to make the slider 7 slide inside the movable groove 6, and then rotate the handwheel 8 into the slider 7, and move one side of the handwheel 8 into the limiting groove 9. At this time, the connecting block 2 is restricted by two groups of handwheels 8 during the rotation process, so as to adjust the maximum rotation angle of the connecting block 2.

[0031] Please refer to Figure 5 、 Figure 6 and Figure 8 ,a blast shield 11 is lapped on the inner wall of the groove 10, a clamping block 12 is arranged on one side of the back of the blast shield 11, a connecting block 13 is arranged on the other side of the back of the blast shield 11, and a connecting groove 14 is opened in the inner wall of the connecting block 13.

[0032] When the explosion-proof shield 11 needs to be used, first align the middle of the explosion-proof shield 11 with the grooves 10 on both sides of the nozzle 5, and align the clamping block 12 with the connecting groove 14. Then, squeeze the explosion-proof shield 11 against each other so that the clamping block 12 snaps into the connecting groove 14, thereby fixing the clamping block 12 into the connecting block 13. After the clamping block 12 is fixed, the two explosion-proof shields 11 are spliced and installed. The explosion-proof shield 11 can protect the user, and the explosion-proof shield 11 has transparency, which is convenient for the user to observe.

[0033] Please refer to Figure 2 and Figure 6 As shown in, a handle 15 is fixedly connected to the back of the guide pipe 4. An anti-slip layer 16 is provided on the surface of the handle 15. Fixed blocks 17 are provided on both sides of the back of the guide pipe 4. Limit blocks 18 are provided at both the bottom and the top of one end of the transport pipe 3.

[0034] The user can hold the handle 15 to adjust the spraying angles of the guide pipe 4 and the nozzle 5. The anti-slip layer 16 can effectively prevent slipping between the palm and the handle 15. The limit block 18 blocks the fixed block 17, thereby restricting the rotation angle of the guide pipe 4.

[0035] Please refer to Figure 3 and Figure 4 As shown in, a sealing ring 19 is provided at the bottom of the base 1. Thread grooves 20 are provided at the four surrounding parts of the inner wall of the base 1. The explosion-proof shield 11 is composed of two spliced parts. The explosion-proof shield 11 is made of polycarbonate PC material and has a certain transparency. The movable groove 6 and the limit groove 9 are both opened in a semi-circular shape, and the movable groove 6 coincides with the limit groove 9. The nozzle 5 is located in front of the groove 10. A booster pump 21 is provided on the inner top wall of the connecting block 2.

[0036] Before using the device, first use bolts to fix the base 1 to the working location through the thread grooves 20. The sealing ring 19 can prevent water leakage after the base 1 is installed. The booster pump 21 can pressurize the water source in the connecting block 2, so that the water column sprayed by the nozzle 5 has greater impact force.

[0037] Working principle: When using a steering component for a law enforcement water cannon operation, first use bolts to fix the base 1 to the working location through the thread grooves 20. Inject the water source into the base 1. The booster pump 21 can pressurize the water source in the connecting block 2 and transport it to the nozzle 5 for spraying, thereby conducting law enforcement. During the law enforcement process, the user can hold the handle 15 to drive the guide pipe 4 and the connecting block 2 to rotate, thereby freely adjusting the spraying angle of the nozzle 5.
