Description

Technical Field

[0001] This utility model relates to the field of water spray gun technology, and in particular to an intelligent control water spray gun. Background Technology

[0002] Sprinkler guns are mainly used for dust control and suppression in stockyards. In existing technology, sprinkler guns utilize the reaction force between the water jet from the nozzle and the distributor to achieve rotation, and mechanical limit switches control the angle and reset the nozzle. However, due to the significant impact and vibration of the reaction force, frequent malfunctions occur, such as the nozzle reset device jamming and the distributor being damaged. This results in the nozzle failing to rotate, the water jet not dispersing properly, and the water directly impacting the stockpile, causing stockpile collapse and severe water accumulation, affecting the quality of cargo transportation. Furthermore, current control methods only allow for the opening and closing of the spray nozzle's water path. In actual use, the spraying area changes with the on-site working environment, requiring manual on-site adjustment of the limit blocks or direct shutdown of the corresponding nozzles to meet the needs. This is cumbersome and lacks precision. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide an intelligent control water spray gun. By using a control method that combines a motor and an encoder, the spray gun rotation angle can be remotely and precisely controlled, thereby improving the timeliness and accuracy of spray gun control.

[0004] To achieve the above technical objectives and requirements, the technical solution adopted by this utility model is as follows: an intelligent control sprinkler gun, including a mounting flange and a control box. A rotating mechanism is provided on the mounting flange. The rotating mechanism is connected to a pitching mechanism through a first bend pipe. The pitching mechanism is connected to a spray pipe through a second bend pipe. Encoders are respectively provided on the rotating mechanism and the pitching mechanism. The encoders send pulse signals to the PLC controller. The PLC controller calculates and controls the motor according to the received pulse signals to achieve precise positioning. A nozzle is connected to the front end of the spray pipe through a nozzle cap. A water outlet adjustment mechanism is provided at the nozzle outlet to adjust the spraying state and switch between shower and long-range spray modes.

[0005] Preferably, the water outlet state adjustment mechanism includes a motor bracket, which is mounted on the spray pipe. A telescopic motor is mounted on the motor bracket, and the push rod of the telescopic motor is connected to the shower head baffle.

[0006] Preferably, the shower head baffle includes a baffle plate, on which triangular brackets are symmetrically arranged. The upper end of the triangular brackets is connected to a push rod by bolts, and the lower end of the triangular brackets is connected to the front end of a motor bracket by bolts.

[0007] Preferably, the rotating mechanism includes a lower joint housing, in which a lower joint worm gear and a lower joint worm are disposed, the lower joint worm gear meshing with the lower joint worm, and the lower joint worm being connected to left and right control motors.

[0008] Preferably, the pitch mechanism includes an upper joint housing, in which an upper joint worm gear and an upper joint worm are disposed, the upper joint worm gear meshing with the upper joint worm, and the upper joint worm being connected to an upper and lower control motor.

[0009] Compared with traditional structures, this utility model offers the following advantages: longer service life, better atomization effect, more uniform spraying, and no blind spots; the spraying state can be adjusted by controlling the push rod through the motor installed at the spray gun head, achieving cruising rotation within a set rotation angle range, with the spraying angle adjustable arbitrarily within -60° to +120°; by installing high-precision encoders on the rotation and pitch mechanisms to emit pulse signals, remote and precise control of the spray gun rotation angle is achieved, significantly improving the timeliness and accuracy of control. This not only effectively solves problems such as cargo pile collapse, severe site water accumulation, and high equipment failure rate, but also significantly improves the quality of freight transportation and the stability of environmental protection practices.

Detailed Implementation

[0012] The present invention will be further described below.

[0013] See attached document Figure 1A smart control sprinkler gun includes a mounting flange 1 and a control box 10. The mounting flange 1 is equipped with a rotating mechanism 2, which is connected to a pitching mechanism 3 via a first bend 9. The pitching mechanism 3 is connected to a spray pipe 8 via a second bend 4. Encoders are respectively installed on the rotating mechanism 2 and the pitching mechanism 3. The encoders send pulse signals to a PLC controller. The PLC controller calculates and controls the motor based on the received pulse signals to achieve precise positioning. The front end of the spray pipe 8 is connected to a nozzle 6 via a nozzle cap 7. A water outlet adjustment mechanism 5 is installed at the outlet of the nozzle 6 to adjust the spraying state.

[0014] In this preferred embodiment, the water outlet state adjustment mechanism 5 includes a motor bracket 51, which is mounted on the spray pipe 8. A telescopic motor 52 is mounted on the motor bracket 51, and the push rod 521 of the telescopic motor 52 is connected to the shower baffle 53.

[0015] In this preferred embodiment, the shower head baffle 53 includes a baffle 531, on which triangular brackets 532 are symmetrically arranged. The upper end of the triangular brackets 532 is connected to the push rod 521 by bolts, and the lower end of the triangular brackets 532 is connected to the front end of the motor bracket 51 by bolts.

[0016] In this preferred embodiment, the rotating mechanism 2 includes a lower joint housing 23, and a lower joint worm gear 24 and a lower joint worm 22 are disposed inside the lower joint housing 23. The lower joint worm gear 24 meshes with the lower joint worm 22, and the lower joint worm 22 is connected to the left and right control motors 21.

[0017] In this preferred embodiment, the pitch mechanism 3 includes an upper joint housing 34, in which an upper joint worm gear 33 and an upper joint worm 32 are disposed. The upper joint worm gear 33 meshes with the upper joint worm 32, and the upper joint worm 32 is connected to the up and down control motor 31.

[0018] In practical implementation, the entire machine body is made of stainless steel to ensure its corrosion resistance and durability, effectively reducing equipment failures. Rotation and pitch are driven by left-right control motors 21 and up-down control motors 21 (with incremental encoders), enabling omnidirectional rotation adjustment in all directions, allowing cruising rotation within a set angle range. The spray angle can be adjusted arbitrarily within -60° to +120°. The motor torque drives the worm gear and worm shaft to move the rotating mechanism. During rotation, the motor encoder sends pulse signals to the PLC. The PLC calculates based on the received pulse signals and precisely controls the motor, allowing for precise adjustment of the pitch angle according to the distance to the pile, avoiding direct impact on the pile and preventing collapse. The water outlet adjustment mechanism 5 installed on the spray gun head controls the push rod 521. The push rod 521 pushes the baffle 531 to rotate along the connection between the baffle 531 and the motor bracket 51, adjusting the spray state and switching between shower and long-range spray modes to achieve optimal spraying effect and eliminate blind spots. To ensure the electric spray gun operates normally within the set spraying range and prevent it from rotating more than 360° due to system malfunctions, a limit switch is installed at the rear of the spray gun. This limit switch is a safety protection device; if the spray gun approaches this device without stopping or changing direction due to a system malfunction, the limit switch will cut off the motor's power supply, thus protecting the spray gun from damage. The drive motor and travel limit switch are integrated into a single design, reducing the motor's size and eliminating the risk of water ingress into the limit switch. After the modification, the efficiency of adjusting the spray gun's rotation angle has been significantly improved. What previously required two people working together for seven hours can now be easily completed by one person in just 10 minutes. This not only effectively solves problems such as cargo pile collapse, severe site water accumulation, and high equipment failure rates, but also significantly improves freight quality and the stability of environmental protection operations.

[0019] The above embodiments of this utility model are merely examples to clearly illustrate this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by each claim.
