[0028] Referring to Figures 1-3 as shown, it is a preferred embodiment provided by the present invention.

[0029] The ship-shore safety device control cabinet includes a cabinet body 10, an electric heater 20, a heat dissipation mechanism 30, and a temperature controller. The electric heater 20 is installed on the heat dissipation mechanism 30. The heat dissipation mechanism 30 is integrated on the inner top and inner side walls of the cabinet body 10 and includes at least one set of angle adjustment mechanisms 40 that can be moved and adjusted; the temperature controller is electrically connected to the electric heater 20 and the heat dissipation mechanism 30;

[0030] The heat dissipation mechanism 30 includes a horizontal slide rail 31, a driving motor 32, a heat dissipation fan 33, and a heat conduction substrate 34. The electric heater 20 is installed on the heat conduction substrate 34. The heat conduction substrate 34 is installed on the heat dissipation fan 33. The heat dissipation fan 33 is installed on a slide seat 35. The heat dissipation fan 33 moves along the direction of the horizontal slide rail 31 through the slide seat 35 in cooperation with the driving motor 32 to dissipate heat from different areas inside the cabinet body 10;

[0031] The heat dissipation mechanism 30 allows the slide seat 35 to move through the horizontal slide rail 31, and uses the driving motor 32 to drive the slide seat 35 to drive the heat dissipation fan 33 to reciprocate along the direction of the horizontal slide rail 31, so as to blow the heat absorbed on the heat conduction substrate 34 to different areas inside the cabinet body 10 for heat dissipation. The electric heater 20 realizes mobile heat dissipation through the slide seat 35 in cooperation with the driving motor 32;

[0032] When the electric heater 20 is not required for heating, the heat dissipation fan 33 can be used to blow air for heat dissipation of locally heated electrical components;

[0033] The temperature controller is connected to a temperature sensor array 50. The temperature sensor array 50 is distributed in multiple partitions inside the cabinet body 10 to form a closed-loop feedback control logic. When the partition temperature difference exceeds the threshold, local heating or directional heat dissipation is started; the temperature controller can perform multi-directional monitoring of the inside of the cabinet body 10 through the temperature sensor array 50 to prevent individual electrical components from overheating or overcooling, resulting in problems where the electric heater 20 and the heat dissipation mechanism 30 cannot perform local heating or directional heat dissipation;

[0034] The angle adjustment mechanism 40 includes a stepper motor 41 and a swing plate 42. The top of the swing plate 42 abuts against the bottom of the cooling fan 33. A semi-circular gear 43 protrudes from the bottom of the swing plate 42. The output shaft of the stepper motor 41 meshes with the semi-circular gear 43. The swing plate 42 is hinged to the sliding seat 35. The pitch angle of the cooling fan 33 is controlled by the stepper motor 41 to adapt the air flow direction to the internal equipment layout of the cabinet 10.

[0035] The angle adjustment mechanism 40 is driven by the output shaft of the stepper motor 41 to mesh with the semi-circular gear 43, thereby controlling the semi-circular gear 43 to drive the swing plate 42 to swing, so that the swing plate 42 drives the cooling fan 33 to change the pitch angle, and the air flow direction is adapted to the internal equipment layout of the cabinet 10.

[0036] For the shore-to-ship safety device control cabinet provided above, the temperature sensor array 50 is used to monitor the inside of the cabinet 10 in multiple directions. The electric heater 20 heats and transfers the heat to the heat conduction substrate 34. The cooling fan 33 blows the heat in the heat conduction substrate 34 into the cabinet 10. The drive motor 32 drives the cooling fan 33 to move along the direction of the transverse slide rail 31 for local heating or directional heat dissipation, integrating the function of mobile heat dissipation. The angle adjustment mechanism 40 controls the pitch angle of the cooling fan 33 through the stepper motor 41 to adapt the air flow direction to the internal equipment layout of the cabinet 10. The temperature controller is used to dynamically coordinate the heating and heat dissipation functions according to the real-time temperature data, solving the problem of equipment failure of the shore-to-ship safety device control cabinet in low temperature conditions.

[0037] In this embodiment, a heat dissipation fin group 341 is arranged on the side of the heat conduction substrate 34 away from the electric heater 20. The heat conduction substrate 34 is installed on the cooling fan 33 through the heat dissipation fin group 341;

[0038] The heat dissipation fin group 341 is composed of multiple aluminum wavy fins arranged in parallel. The distance between adjacent fins is 5-8 mm, and the surface of the fins is coated with a graphene heat conduction coating.

[0039] The heat conduction substrate 34 increases the heat dissipation effect and transfer effect through the heat dissipation fin group 341.

[0040] In this embodiment, an air flow gap is formed between the heat dissipation fin group 341 and the cooling fan 33. The heat dissipation fin group 341 and the cooling fan 33 are connected by a fixing rod 342. In this way, space can be provided for the heat dissipation of the heat dissipation fin group 341, avoiding that the heat on the heat dissipation fin group 341 cannot be dissipated or affecting the heat dissipation effect. The connection relationship between the heat dissipation fin group 341 and the cooling fan 33 can be increased through the fixing rod 342.

[0041] In this embodiment, limit switches 36 are provided on both sides of the horizontal slide rail 31. The limit switches 36 are electrically connected to the drive motor 32 to limit the movement range of the cooling fan 33 and prevent interference with the internal electrical components of the cabinet 10.

[0042] When the slide seat 35 moves to both sides of the horizontal slide rail 31 and triggers the limit switch 36, the limit switch 36 can drive the slide seat 35 to move in the reverse direction through the drive motor 32.

[0043] In this embodiment, a moisture-proof layer 11 is provided at the inner bottom of the cabinet 10. A humidity sensor 12 is embedded in the moisture-proof layer 11. The humidity sensor 12 is electrically connected to the temperature controller. When the humidity sensor 12 detects that the humidity is too high, the temperature controller triggers the electric heater 20 to dehumidify the interior of the cabinet 10.

[0044] Intelligent regulation: The temperature / humidity sensor 12 is linked with the regulating valves of the cooling fan 33 and the electric heater 20, and can automatically adjust the cooling intensity according to environmental parameters to avoid equipment failures caused by overheating or overcooling.

[0045] In this embodiment, the electric heater 20 uses a PTC ceramic heating sheet, the surface of which is covered with an antioxidant coating, and is in relative abutment with the heat conduction substrate 34 of the heat dissipation mechanism 30 to form an optimized heat exchange layout.

[0046] In this embodiment, the data of the temperature sensor array 50 is transmitted to the external monitoring terminal through the wireless communication module, which supports remote adjustment of the heating and cooling strategies. The temperature controller is connected with an over-temperature protection circuit. When abnormal temperature or cooling failure is detected, the power supply of the electric heater 20 is automatically cut off and an audible and visual alarm is triggered. In this way, it is convenient for users to monitor the faults of the cabinet 10 in real time so as to solve the problems in time.

[0047] In this embodiment, a cabinet door 13 is installed on the cabinet 10. A detachable flow guide plate 14 is arranged on the inner side of the cabinet door 13. The flow guide plate 14 is arranged in an inclined shape, and honeycomb-shaped air flow channels 15 are distributed on the surface of the flow guide plate 14 to guide the uniform diffusion of the cooling air flow, improve the cooling range and the heat recovery utilization rate.

[0048] In this embodiment, the heat conduction substrate 34 is connected to an external condensing pipe, and forms a composite cooling mode by working together with the cooling fan 33 through circulating coolant. In this way, when the temperature sensor array 50 detects that individual electrical components are heated up, the coolant circulation of the heat conduction substrate 34 can be cooled down through the external condensing pipe, so as to cooperate with the cooling fan 33 to cool it down, which can improve the effect and efficiency of directional cooling, and can also cool down in time when the electric heater 20 is abnormal, increasing the safety of the cabinet 10.

[0049] In this embodiment, a wind guide cover 37 is provided on the cooling fan 33. The wind guide cover 37 is wrapped around the outside of the cooling fan 33. There is a wind guide cavity 371 for gas flow in the wind guide cover 37. A spiral flow guide groove 372 is provided on the inner wall of the wind guide cavity 371. The electric heater 20 and the heat conduction substrate 34 are both located in the wind guide cavity 371. A detachable activated carbon filter 373 is provided at the air inlet of the wind guide cover 37. A snap structure is provided at the edge of the activated carbon filter 373 for quick connection with the housing.

[0050] The wind guide cover 37 surrounds the cooling fan 33 and the electric heater 20, and the activated carbon filter 373 is provided at the air inlet of the wind guide cover 37 to filter the air, preventing a large amount of dust from adhering to the cooling fan 33 and thus affecting the rotation of the cooling fan 33. The wind guide cover 37 can accelerate the flow rate of the air flow by means of the spiral flow guide groove 372, thereby improving the efficiency of local heating or directional heat dissipation.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
