[0034] In this embodiment, it is further set that a pair of monitoring components and positioning components are respectively installed at the upper end of the upper air pump 1.
[0035] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.
[0036] Embodiment: 1. An electric lifting structure is adopted, using the bottom as a pressure sensor to control the stop of the compression depth. The upper part is used as the pressing part and is controlled by the lower pressure sensor. When collecting garbage, the bottom support automatically sends the garbage out of the bucket opening.
[0037] 2. Equipment movement principle: The vision design consists of two front cameras for sampling and transmitting to the single-chip microcomputer control center. The positions of the two cameras rely on the top compression support and provide a 120° panoramic view. Identify the garbage in front (in this model demonstration, the garbage is replaced by three types of target objects: red, blue, and green). Transmit the data to the single-chip microcomputer for analysis and processing, and then transmit the control to the lower-level motor to operate. Note: When the two cameras sample simultaneously, the right camera has priority control to operate.
[0038] 3. Wave energy generation device: Under the excitation of waves, the outer floating body tilts, and the component of the gravity of the internal eccentric pendulum in its rotation plane continuously changes, driving the eccentric pendulum to rotate around the central axis of the device. This rotational motion is finally input into the PTO after speed regulation to generate electricity.
[0039] Biological protection system: Since there are often organisms such as fish in the water area, to prevent mis-capture during identification, the device will identify organisms through the identification device. When organisms such as fish appear, the baffle will rise to prevent the organisms from entering the device.
[0040] The device mainly consists of four major parts: an outer floating body, a bearing, an eccentric pendulum, and an energy conversion system (power take-off system, PTO). Among them, the eccentric pendulum, energy conversion system, etc. are installed inside the fully enclosed outer floating body, which can effectively prevent the key components from being corroded by seawater and improve the reliability of the device. Under the excitation of waves, the outer floating body tilts, and the component of the gravity of the internal eccentric pendulum in its rotation plane continuously changes, driving the eccentric pendulum to rotate around the central axis of the device. This rotational motion is finally input into the PTO after speed regulation to generate electricity, and it is placed at the lower part of the main body mechanism.
[0041] This device works in the water area. Using OpenCV combined with machine learning or deep learning, it preprocesses, segments, extracts features, locates targets, and classifies the sea surface images to identify and collect the garbage on the sea surface. To solve the problem of the disturbance of water surface fluctuations to the balance maintenance and movement of the device, by moving the ballast water inside the device and using an adjustable ballast tank to change the center of gravity position of the device, the dynamic adjustment of the center of gravity of the device is realized to stabilize the device. Sealing, potting, coating and other methods are adopted to prevent the electronic equipment from being affected by moisture, water ingress or other liquid erosion.
[0042] Remote control: The remote control is realized through the cooperation of the Arduino module and the HC6.0 Bluetooth module. The supporting mobile phone app can locate and find the device, and at the same time remotely control the device to move.
[0043] Automatic control: When the device moves, the camera at the front end of the device will achieve autonomous operation of the device through OpenMV. When the left camera detects an object, it will transmit a signal to the right motor, so as to realize the rotation and movement of the device to the left; similarly, the right side has the same effect. When both cameras detect an object at the same time, the two motors will run simultaneously to achieve the effect of moving forward.
[0044] The overall forward movement relies on the reaction force provided when the bottom water pump pumps out water. Consider two situations of power magnitude:
[0045] 1. When the power is too small, add a tail fan structure to provide additional forward kinetic energy.
[0046] 2. Only rely on the reaction kinetic energy of local drainage to meet the forward kinetic energy demand of the overall equipment.
[0047] The model of this device is too small in volume and has a small mass inertia, so the second design is adopted.
[0048] The forward power design and its parameters are as follows (the same as the water inlet pump of the water tank):
[0049]
[0050]
[0051] Water level measurement: Through the water level measurer in the bucket, the water content in the bucket is detected. If it is higher than the warning water level line, the power of the drainage water pump is increased. If it is lower than the minimum limit, the power of the water pump is decreased. In addition, the sensor senses and the two pumps in the "submarine-like water tank" are adjusted to balance the water inlet and drainage of the water tank, so as to achieve the balance of water inlet in the middle of the bucket.
[0052] Mid-section water inlet balance.
[0053] Garbage compression: There are telescopic pressure rods up and down. When the garbage is stored to a certain amount, the garbage can be automatically compressed to increase the space storage capacity. When the compression pressure cannot compress, it alarms that it is full and stops working. The water inlet pump in the "submarine-like water tank" stops working, and the drainage water pump discharges the water in the water tank - the device rises and the middle stops water inlet.
[0054] Theoretical design calculation
[0055] Calculation of the weight of the barrel body and various carrying devices:
[0056] m1 = Barrel body weight (3680) + Lift weight (1000) + Two power motors (2 * 128) + Three water pumps weight (3 * 248) + Filter screen (1000) + Other equipment (circuit board, gel total 400) = 7080g = 7.08kg
[0057] Maximum weight of garbage and moisture in the barrel:
[0058] Barrel body diameter d = 250mm
[0059] Barrel body height h = 300mm
[0060] Calculated according to the maximum weight limit of half a barrel of water:
[0061] m2 = 3.14 * (d / 2)^2 * (h / 2) * 1 = 12.785kg
[0062] Maximum total weight of the entire system:
[0063] m1 + m2 = 19.865kg
[0064] Maximum buoyancy:
[0065] F = 19.865 * 9.8 = 194.677N
[0066] Calculation of water inlet and discharge duration of the water sump:
[0067] Volume of the water sump:
[0068] V = 3.14 * (25 * 25 - 12.5 * 12.5) * 10 = 14718cm^3
[0069] Pumping speed of the water pump:
[0070] 600L / H = 167cm^3 / S
[0071] Duration required to fill the water:
[0072] 14718 / 167 = 88S
[0073] Volume of the water sump is:
[0074] 3.14 * (15 * 15 - 12.5 * 12.5) = 215.875cm^3 / S
[0075] The increased weight of the barrel body for half a barrel is 687.5g, it can dive to the working water level, the pumping time is 44s, less than one minute. The power of the discharge water pump is 2w, the flow rate is 250l / h, and the drainage duration is 76s.
[0076] The equipment has obtained the best working balance rate through repeated experiments.
[0077] 4 Performance Testing and Analysis
[0078] After the development was completed, experimental tests were carried out. During the testing process, based on the built-in eccentric pendulum wave energy generation device, the endurance of the garbage cleaning device was effectively improved, and the maintenance cost of the equipment was reduced.
[0079] Main issues considered during the design based on appropriate adjustments to the device after testing:
[0080] Control of buoyancy - preventing sinking, emergency measures taken
[0081] 1. The water tank increases drainage to increase buoyancy and reduce gravity.
[0082] 2. The middle drainage pump works at full power to prevent sinking.
[0083] 3. The fan blades work at high power to quickly sail towards the shore for remedy.
[0084] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
