Technical Field

[0002] Ship unloaders play a crucial role in port cargo handling operations, and their prolonged operation generates significant heat in critical components such as motors and hydraulic systems. Existing ship unloader cooling systems often employ fixed-speed fans or fixed-flow cooling pumps, which present the following problems: The cooling system operates at a constant power output regardless of equipment load, resulting in energy waste. It cannot dynamically adjust the cooling intensity based on the actual heat generated by the equipment, potentially leading to insufficient cooling under high load conditions, affecting equipment stability and lifespan. Furthermore, the cooling area is relatively fixed, preventing flexible adjustment of the cooling airflow path and resulting in poor applicability.
[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a cooling structure for the hydraulic system of a bulk carrier loading and unloading crane [201210108123.8], which includes a base, a movable tower mounted on the upper end of the base via a slewing bearing, a slewing drive hydraulic motor between the movable tower and the base, a luffing winch and a hoisting winch driven by a luffing hydraulic motor and a hoisting hydraulic motor respectively on the movable tower, a heat exchange plate at the top of the movable tower, the flow channels of the heat exchange plate being connected in series in the hydraulic pipeline of the hydraulic station, a temperature sensor installed in the hydraulic oil tank of the hydraulic station, and a cooling fan driven by a motor installed on one side of the heat exchange plate; both the motor and the temperature sensor are connected to the control system.
[0004] The above solution has solved the problem of hydraulic cooling of ship unloaders to a certain extent, but it still has many shortcomings, such as fixed cooling air path and poor applicability. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned problems by providing a visually-based vector cooling device for ship unloaders that is reasonably designed and allows for flexible adjustment of the cooling airflow path.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vector cooling device for a ship unloader based on visual recognition, comprising a visual recognition module installed on the ship unloader, the visual recognition module being connected to a blowing cooling assembly via a PLC unit, the blowing cooling assembly including a variable frequency cooling fan, the variable frequency cooling fan being connected to a vector spray assembly, and the visual recognition module employing a high-resolution infrared thermal imaging camera or a multispectral visual sensor.

Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] like Figure 1-4 As shown, a vision-based vector cooling device for a ship unloader includes a vision recognition module 1 installed on the ship unloader. The vision recognition module 1 is connected to a blowing cooling assembly 2 via a PLC unit. The blowing cooling assembly 2 includes a variable frequency cooling fan 21, which dynamically adjusts its output air pressure and air volume according to PLC instructions to adapt to different cooling needs and optimize energy consumption. The variable frequency cooling fan 21 is connected to a vector spray assembly 3. The vision recognition module 1 uses a high-resolution infrared thermal imaging camera or a multispectral vision sensor to identify the specific location of high-temperature thermoelectricity in the ship unloader's hydraulic system or motor.
[0024] Specifically, the vector injection assembly 3 includes a cooling air duct 31, which is installed on the ship unloader as needed. A blower head 32 is provided at the end of the cooling air duct 31, and a spray nozzle 33 is movably connected inside the blower head 32 through a directional assembly 4. The spray nozzle 33 guides the airflow and accelerates the airflow to improve the cooling effect.
[0025] In detail, the directional assembly 4 includes an electric push rod 41 arranged symmetrically with respect to the blower head 32. The electric push rod 41 has a built-in high-precision position encoder. The electric push rod 41 is connected to the nozzle 33 via a universal joint 42, which can realize the precise directional adjustment of the nozzle 33 in the adjustment cavity 34 around its center of sphere with two degrees of freedom: pitch ±30° and yaw ±45°.
[0026] Furthermore, the blower head 32 has an internally hemispherical adjustment cavity 34, and the nozzle 33 is spherical and installed inside the adjustment cavity 34. The spherical mating area uses a composite sealing material with a low coefficient of friction and high wear resistance to ensure a tight seal. One side of the nozzle 33 is connected to the cooling blower pipe 31 through a bellows, which provides the necessary flexible connection to compensate for the displacement and stress generated when the nozzle 33 is adjusted. The other side of the nozzle 33 is provided with a spray port 35, and the spray port 35 is equipped with an opening and closing assembly 5. The spray port 35 can be selected as circular or flat fan-shaped as needed to adapt to the cooling requirements of heat sources of different shapes.
[0027] Furthermore, the opening and closing assembly 5 includes an opening and closing plate 51 inside the nozzle 35. The opening and closing plate 51 is arc-shaped and is connected to the electric telescopic rod 52. The curvature of the opening and closing plate 51 matches the inner wall of the nozzle 35, forming a good airtight seal when closed. The electric telescopic rod 52 is fixedly installed inside the nozzle 33 and extends along the central axis of the nozzle 33. The stroke of the electric telescopic rod 52 precisely controls the opening degree of the opening and closing plate, realizing stepless flow rate adjustment of the jet airflow from 0% to 100%. A spiral guide vane 53 is installed between the electric telescopic rod 52 and the inner wall of the nozzle 33. The spiral guide vane 53 converts the axial airflow entering the nozzle 33 into a strong rotating flow, improving the heat exchange efficiency and coverage uniformity between the airflow and the heat source surface, while also helping to stabilize the jet shape.
[0028] In addition, the cooling air duct 31 is composed of several branch pipes 36, which are made of lightweight, high-strength aluminum alloy or composite materials and have a smooth interior to reduce flow resistance. Adjacent branch pipes 36 are connected by pressure-resistant corrugated pipes, and the entire piping system is designed with a heat insulation layer to reduce the loss of cold energy during transportation.
[0029] Meanwhile, the PLC unit is connected to a temperature sensor via a wireless transmission unit. The temperature sensor is located on the ship unloader, typically at key monitoring points such as the motor housing, gearbox, hydraulic station, bearing housing, and grab bucket hinge point.
[0030] As can be seen, the vector injection assembly 3 has a built-in flow sensor and a temperature sensor. The flow sensor and the temperature sensor are connected to the wireless transmission unit. The flow sensor is usually a thermal mass flow meter, and the temperature sensor is a patch PT100 or a thermocouple. The actual injection flow rate and the airflow temperature at the injection port are fed back to the PLC unit in real time to form a closed-loop control, ensuring that the cooling effect is accurate and controllable.
[0031] It is clear that the vector injection assembly 3 and the vision recognition module 1 are positioned opposite the hydraulic system of the ship unloader to avoid vibration and oil contamination of the hydraulic system. They are usually also equipped with physical isolation or buffer devices.
[0032] Preferably, the vector injection component 3 is covered with a reflective coating on its outer side to effectively reflect ambient radiant heat and reduce its own temperature rise.
[0033] In summary, the principle of this embodiment is as follows: the visual recognition module 1 uses thermal imaging positioning to drive manual inspection, the variable frequency cooling fan 21 extends and adjusts the cooling airflow path through the vector injection component 3, the vector injection component 3 can adjust its own airflow direction, and under the control of the PLC unit, it is opposite to the heat points such as the hydraulic system, thereby improving the cooling efficiency and overall energy efficiency.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0035] Although this document frequently uses terms such as visual recognition module 1, air-blowing cooling assembly 2, variable frequency cooling fan 21, vector jet assembly 3, cooling air duct 31, blower head 32, jet nozzle 33, adjusting chamber 34, jet outlet 35, branch pipe body 36, directional assembly 4, electric push rod 41, universal linkage 42, opening and closing assembly 5, opening and closing plate 51, electric telescopic rod 52, and spiral guide vane 53, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
