Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment and relates to a small-sized garbage collecting remote-controlled boat system. Background Art

[0002] The problem of garbage on the surface of small water bodies is a difficult problem faced by water environment management. Usually, there are a lot of garbage on the surface of small water bodies in cities and villages, as well as artificial water bodies in tourist attractions and parks. These garbage on the surface of water will not only affect the appearance, but also have a certain impact on water sources, aquatic organisms, water quality, etc., and will also damage the ecological environment and human health.

[0003] To solve the problem of surface garbage in small waters, it is necessary to use a combination of methods, including physical cleaning, chemical treatment, and biological restoration.

[0004] Physical cleaning is the most commonly used method, including manual cleaning, mechanical cleaning, net capture, etc. Manual cleaning is suitable for areas with smaller water areas, mainly using manual cleaning of water surface garbage.

[0005] Mechanical cleaning mainly uses machines such as pumping equipment, boats and road-sweeping vehicles, which are relatively efficient. Chemical treatment mainly uses chemical agents to decompose and degrade surface garbage, but the use of chemical agents will have toxic effects on water bodies, so it is necessary to pay attention to the dosage and use of the agents. Biological restoration mainly uses microorganisms, plants or ecological engineering to biodegrade and repair surface garbage.

[0006] To sum up, when cleaning up garbage in small water bodies with ornamental functions such as cities and scenic spots, we must not only consider whether the cleaning will damage the beauty of the environment, but also pay attention to reducing the generation of odors and toxic substances. Therefore, physical cleaning methods are the most reasonable and effective. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1 As shown, a small-scale garbage collection remote control boat system disclosed in this embodiment includes a visual operation control module, a motion control module, a camera module, a wireless communication module, a propeller drive module, a DC reduction motor drive module, an ultrasonic ranging module, a buzzer and a power supply module; the signal input end of the visual operation control module is electrically connected to the wireless communication module and the camera module; the motion control module controls the connection of the propeller drive module, the DC reduction motor drive module, the ultrasonic ranging module and the buzzer respectively through electrical signals; one end of the DC reduction motor drive module outputs an electronic control drive to control the net bag motor of the collection device in the remote control boat to realize the closing and opening functions of the net bag, and the other end outputs and connects to the propeller drive module, and drives the propeller through the propeller drive module to cooperate with the propeller motor of the remote control boat to drive the propeller; the visual operation control module is also electrically connected to the motion control module to form a dual control module that cooperates with each other, which can realize the motion control of the boat and the precise positioning of the garbage collection location; the power supply module provides power for the system.

[0030] like Figure 2 As shown, the visual operation control module adopts the ESP32CAM development board. The development board integrates a WIFI module and an OV2640 camera on board, which meets the design requirements very well. At the same time, it is inexpensive and effectively controls costs. The ESP32CAM development board is equipped with an ESP32-S chip, a camera module, a reset module, a buck module, a microSD card slot module, a flash module, and a PSRAM pseudo-static random access memory module. The ESP32-S chip leads out the download pin and the GPIO available to users, and is also equipped with three GND pins and two power input pins: 3.3V and 5V. Since ripples and even report errors are prone to occur when using 3.3V for power supply, it is a better choice to use 5V2A DC for power supply. There is also a power output port on the development board, and the user can choose the output voltage by himself. The output voltage of 5V or 3.3V can be selected by welding or desoldering the 0R resistor near the pin;

[0031] The motion control module uses the RT1052DVL6B minimum system board as the control board. In addition to the microcontroller, the minimum system board also requires peripheral circuits to assist in forming a complete control module. The peripheral circuits include: power supply circuit, oscillation circuit and reset circuit to assist the microprocessor to work normally. In addition, the SWD download port is led out to burn the program, and the remaining buttons and indicator lights are led out as needed. The unused pins are led out with pin headers for subsequent use.

[0032] The power module includes a 12V battery, a 12V distribution board and a 5V distribution board. The 12V battery is electrically connected to the power input end of the 12V distribution board, and the power output end of the 12V distribution board is electrically connected to the propeller drive module and the DC reduction motor drive module; the 5V distribution board is electrically connected to the DC reduction motor drive module.

[0033] like Figure 5 As shown, the DC reduction motor drive module uses an L298N drive chip, which integrates a switching voltage regulator, namely an LM2596 step-down chip, for outputting a 5V voltage. The output end of the switching voltage regulator is electrically connected to the input end of the 5V distribution board, and the output end of the 5V distribution board is electrically connected to the visual operation control module and the motion control module. Figure 3 As shown, the 12V battery supplies power to the propeller drive module and the DC reduction motor drive module through the 12V distribution board. The LM2596 step-down chip in the DC reduction motor drive module reduces the 12V input voltage to 5V to power the RT1052 control board and the ESP32CAM development board. The ESP32CAM development board supplies power to the camera, and the RT1052 control board supplies power to the ultrasonic sensor module and the buzzer module respectively. In addition, the AMS1117 step-down chip on the RT1052 control board reduces the 5V input to 3.3V to power the RT1052DVL6B chip of the motion control module. Figure 4 shown.

[0034] like Figure 6 As shown, the propeller drive module adopts the H-bridge drive circuit of ZK-5AD, which has a greater driving capacity. Each channel can output 5A current, with a maximum of 9A, to ensure the stable operation of the remote control boat.

[0035] The ultrasonic distance measurement module uses HV-SR04 ultrasonic sensor for distance measurement. It is composed of a transmitter, a receiver and a control circuit. It has four pins, namely VCC power supply, GND grounding, Trig trigger, and Echo echo. It is connected to the motion control module control board to achieve communication. The ultrasonic sensor can be used in a distance measurement environment of 2~400cm, with a distance measurement accuracy of up to 3mm. It works in the state of 5V12mA and the operating frequency is 40kHz.

[0036] The buzzer uses an active low-level triggered buzzer module. After power-on, the alarm function can be realized by pulling down the I / O pin. The VCC pin of the active low-level triggered buzzer module is connected to the 5V output port of the motion control module control board, the GND pin is connected to the GND of the control board, and the I / O pin is connected to the IO port PB15 of the control board.

[0037] In summary, the working principle of the utility model is: two control boards are used, one is the ESP32CAM development board, and the other is the RT1052 control board. The two control boards perform their respective functions and jointly complete the control task of the remote control boat. The ESP32CAM board integrates a WIFI module and is equipped with an OV2640 camera, which meets most of the requirements for visual operation of the remote control boat, but it has only 4 disposable pins, which cannot meet the requirements of remote control boat movement, net collection and distance alarm, so an RT1052 control board is added to complete the remaining control tasks.

[0038] The power of the remote control boat is provided by two propeller motors connected to the propellers. The pin output of the RT1052DVL6B control board is not enough to drive the propeller motors to rotate, so it is necessary to equip the propeller motors with a propeller drive module. The propeller drive module is a ZK-5AD DC motor drive module, which has four control modes and can well execute the start, stop and reversal of the motor. The remote control boat is also equipped with two other DC reduction motors to complete the closing and opening functions of the net bag, and the corresponding driver module chip uses L298N.

[0039] The 12V battery on the ship is first connected to a distribution board to expand the power output interface, and both drive modules are connected to the distribution board to realize the power supply to the drive modules. An LM2596 switching voltage regulator is integrated in the L298N DC reduction motor drive module, which can output a stable 5V voltage. The 5V voltage output by the L298N DC reduction motor drive module is connected to another distribution board, and two 5V DC power is connected from it to power the two control boards.

[0040] The two ultrasonic ranging modules and one buzzer module connected to the RT1052 control board are used for distance alarm. The ultrasonic module will send ultrasonic waves in real time to monitor the distance from the shore on both sides of the hull and return the distance data to the control board. After the control board processes the data, if it finds that the distance is less than the set value, it will drive the buzzer to sound to remind the operator to pay attention to the ship's route.

[0041] The small-scale garbage collection remote-controlled boat proposed by the utility model can replace manual work in collecting garbage on the water surface far from the shore, and can also replace large-scale garbage cleaning boats to collect garbage, thereby solving the problem that garbage collection is time-consuming and labor-intensive and has limited water areas, and improving operation efficiency and work aesthetics.

[0042] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. In the present utility model, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0043] The above is only a preferred implementation case of the utility model, and does not limit the utility model in any form. Although the implementation process of the utility model is described in detail above, for those familiar with the art, they can still modify the technical solutions recorded in the above examples, or replace some of the technical features therein with equivalents. All modifications and equivalent replacements made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
