Description

Technical Field

[0001] This application belongs to the field of marine technology, specifically a ventilation and heat dissipation control device for a ship's engine room. Background Technology

[0002] Marine propulsion is the energy system that provides propulsion to a ship and maintains the operation of various onboard equipment. It mainly consists of engines, transmission systems, propellers, and related auxiliary equipment. Activating cooling equipment and expelling hot air ensures that the temperature inside the engine room is maintained within a suitable range for the operation of the power equipment, preventing performance degradation, malfunctions, or even damage due to high temperatures.

[0003] However, the existing device does not have a component to monitor the composition of gases when hot air is discharged from the engine room. It cannot detect the air composition inside the engine room, cannot confirm the environmental conditions inside the engine room, and cannot provide protection for the life safety of crew members preparing to enter the engine room. Utility Model Content

[0004] The purpose of this application is to provide a ventilation and heat dissipation control device for a ship's power room, in order to solve the problem that the aforementioned device does not have a component for monitoring the gas composition when hot air is discharged from the engine room, thus making it impossible to detect the air composition inside the engine room and confirm the environmental conditions inside the engine room, thereby failing to ensure the safety of the crew members preparing to enter the engine room.

[0005] The technical solution adopted in this application is as follows: it includes a ventilation duct, and multiple support frames are fixedly installed on the rear side of the ventilation duct. The support frames have positioning grooves inside. A gas composition sensor is fitted to the inner side of the support frame. Positioning blocks are fixedly installed on the outer surfaces of the left and right sides of the gas composition sensor. Threaded holes are opened inside the positioning grooves and positioning blocks. Bolts are installed in the threads inside the threaded holes.

[0006] By adopting the above technical solution, multiple support frames are fixedly installed inside the rear side of the ventilation duct. Positioning grooves are opened inside the support frames, and gas composition sensors are fitted onto the inner side of the support frames. Positioning blocks are fixedly installed on the left and right outer surfaces of the gas composition sensors. Threaded holes are opened inside the positioning grooves and positioning blocks, and bolts are installed through the threads inside the threaded holes. The ventilation duct serves as the installation base for the ventilation components, providing a location for the ventilation equipment. The support frames provide support for the monitoring components installed inside the ventilation duct. The positioning grooves provide conditions for fixing the monitoring components inside the ventilation duct. The gas composition sensor, as the main device of the monitoring components, uses a carbon monoxide sensor to monitor the heat from the power compartment drawn into the ventilation components. The carbon monoxide content in the air can confirm the environmental conditions inside the engine room, ensuring the safety of crew members entering this relatively enclosed space. The positioning block is used to accurately install the gas composition sensor into the support frame. It uses a combination of threaded holes and bolts. The threaded holes provide the conditions for the through connection between the positioning slot and the positioning block, and the bolts can connect the two threads, so that the gas composition sensor can be fixed in the outer surface of the support frame. By installing the component that monitors the gas composition when hot air is discharged from the engine room, the air composition inside the engine room can be detected, confirming the environmental conditions inside the engine room and ensuring the safety of crew members preparing to enter the engine room.

[0007] In a preferred embodiment, a mounting base is fixedly installed on the outer surface of the ventilation duct, and a control box is fixedly installed on the left outer surface of the ventilation duct.

[0008] By adopting the above technical solution, a mounting base is fixedly installed on the outer surface of the ventilation duct, and a control box is fixedly installed on the left outer surface of the ventilation duct. The mounting base provides conditions for the device to be fixed to the cabin wall, and the control box can view and control the status and parameters of the device, providing conditions for local control of the device.

[0009] In a preferred embodiment, a groove is fixedly installed on the rear outer surface of the ventilation duct, and a frame is fitted inside the groove.

[0010] By adopting the above technical solution, a sliding groove is fixedly installed on the rear outer surface of the ventilation duct, and a frame is installed inside the sliding groove. The sliding groove provides conditions for the frame to be installed at the rear of the ventilation duct, and the frame provides a position for the installation of the filter assembly.

[0011] In a preferred embodiment, sliders are fixedly installed on the left and right outer surfaces of the frame, and a handle is fixedly installed on the rear side of the frame.

[0012] By adopting the above technical solution, sliders are fixedly installed on the outer surfaces of the left and right sides of the frame, and a handle is fixedly installed on the rear side of the frame. The sliders allow the frame to fit against the slide groove, so that it can be fixed at the rear of the ventilation duct. The handle makes it convenient for workers to remove the frame from inside the slide groove to inspect the equipment inside the ventilation duct.

[0013] In a preferred embodiment, a protective net is fixedly installed on the inner rear part of the frame, and a porous ceramic filter screen is fixedly installed on the inner front part of the frame.

[0014] By adopting the above technical solution, a protective net is fixedly installed on the inner rear side of the frame, and a porous ceramic filter is fixedly installed on the inner front side of the frame. The combination of the protective net and the porous ceramic filter is used. The protective net is used to prevent external foreign objects from being sucked into the ventilation duct and damaging the ventilation components. The porous ceramic filter is based on ceramic material and has a large number of uniformly distributed micropores to filter impurities in the air. In addition, the porous ceramic filter has low gas adsorption and can ensure the integrity of gas composition. Its pore structure is conducive to gas flow, allowing gas to pass through and contact the sensor quickly, reducing detection delay.

[0015] In a preferred embodiment, a servo motor is fixedly installed on the front side of the interior of the ventilation duct, and a fan blade is fixedly installed on the front side of the servo motor.

The servo motor serves as the power source to drive the fan blade to rotate, thereby achieving the ventilation effect. The fan blade rotates under the drive of the servo motor, thereby promoting air circulation and expelling the hot air inside the power compartment from the device.

[0017] In a preferred embodiment, an electric air valve is fixedly installed on the front side of the ventilation duct.

[0018] By adopting the above technical solution, an electric air valve is fixedly installed on the front side of the ventilation duct. The opening of the electric air valve can be precisely adjusted to control the airflow discharged from the engine compartment.

[0019] In a preferred embodiment, a one-way air valve is fixedly installed on the front side of the electric air valve.

[0020] By adopting the above technical solution, a one-way air valve is fixedly installed on the front side of the electric air valve. The one-way air valve only allows air to flow in one direction. When the air pressure in the air duct changes, especially when the ventilation components stop operating or the external air pressure fluctuates, it can effectively prevent air from flowing back into the power compartment.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0022] In this application, the positioning slot can provide a setting condition for fixing the monitoring component inside the ventilation duct. The gas composition sensor, as the main equipment of the monitoring component, adopts a carbon monoxide sensor to monitor the carbon monoxide content of the hot air from the engine room drawn in by the ventilation component. This can confirm the environmental conditions inside the engine room and provide protection for the life safety of the crew entering this relatively enclosed space. By installing a component in this device to monitor the gas composition when the hot air inside the engine room is discharged, the air composition inside the engine room can be detected, and the environmental conditions inside the engine room can be confirmed, thus providing protection for the life safety of the crew preparing to enter the engine room.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-4The system includes a ventilation duct 1, which serves as the mounting base for the ventilation components and provides a location for the installation of the ventilation equipment. A support frame 2 provides support for the monitoring components installed inside the ventilation duct 1. A positioning groove 3 provides conditions for fixing the monitoring components inside the ventilation duct 1. A gas composition sensor 4, the main device of the monitoring components, uses a carbon monoxide sensor to monitor the carbon monoxide content of the hot air from the engine room drawn in by the ventilation components. This allows for confirmation of the environmental conditions inside the engine room, ensuring the safety of crew members entering this relatively enclosed space. A positioning block 5 is used to accurately install the gas composition sensor 4 into the support frame 2. It uses a combination of threaded holes 6 and bolts 7. The threaded holes 6 provide conditions for the through connection between the positioning groove 3 and the positioning block 5, and the bolts 7 connect the two threads, allowing the gas composition sensor 4 to be fixed in the outer surface of the support frame 2. By installing the components that monitor the gas composition when hot air is discharged from the engine room, the air composition inside the engine room can be detected, confirming the environmental conditions inside the engine room and ensuring the safety of crew members preparing to enter the engine room.

[0030] Reference Figure 1 , Figure 2 and Figure 4 Mounting bracket 8 provides conditions for the device to be fixed to the cabin wall, while control box 9 can view and control the status and parameters of the device, providing conditions for local control of the device.

[0031] Reference Figure 2 The chute 10 provides a space for the frame 11 to be installed at the rear of the ventilation duct 1, and the frame 11 provides a location for the installation of the filter assembly.

[0032] Reference Figure 2 The slider 12 allows the frame 11 to fit against the slide 10, so that it can be fixed at the rear of the ventilation duct 1. The handle 13 makes it easy for workers to remove the frame 11 from inside the slide 10 to inspect the equipment inside the ventilation duct 1.

[0033] Reference Figure 2 and Figure 4 The system employs a combination of a protective mesh 14 and a porous ceramic filter 15. The protective mesh 14 is used to prevent external foreign objects from being sucked into the ventilation duct 1 and damaging the ventilation components. The porous ceramic filter 15 is based on ceramic material and has a large number of uniformly distributed micropores to filter impurities in the air. Furthermore, the porous ceramic filter 15 has low gas adsorption capacity, which can ensure the integrity of the gas composition. Its pore structure is conducive to gas flow, allowing the gas to pass through quickly and contact the sensor, reducing detection delay.

[0034] Reference Figure 4The servo motor 16 serves as the power source for driving the fan blades 17 to rotate, thereby enabling the fan blades 17 to rotate and achieve the ventilation effect. The fan blades 17 are driven by the servo motor 16 to rotate, thereby promoting air circulation and expelling the hot air inside the power compartment from the device.

[0035] Reference Figure 1 The electric air valve 18 can be used to precisely adjust the opening, thereby controlling the airflow discharged from the engine compartment.

[0036] Reference Figure 1 The one-way valve 19 only allows air to flow in one direction. When the air pressure in the duct changes, especially when the ventilation components stop operating or the external air pressure fluctuates, it can effectively prevent air from flowing back into the engine compartment.

[0037] The implementation principle of an embodiment of a ship's engine room ventilation and heat dissipation control device is as follows: Ventilation duct 1 serves as the installation base for ventilation components, providing a location for the installation of ventilation equipment. Support frame 2 provides support for the monitoring component installed inside the ventilation duct 1. Positioning groove 3 provides conditions for fixing the monitoring component inside the ventilation duct 1. Gas composition sensor 4, as the main equipment of the monitoring component, uses a carbon monoxide sensor to monitor the carbon monoxide content of the hot air from the engine room drawn in by the ventilation component, thus confirming the environmental conditions inside the engine room and ensuring the safety of crew members entering this relatively enclosed space. Positioning block 5 is used to accurately install the gas composition sensor 4 into the support frame 2, using a combination of threaded hole 6 and bolt 7. Threaded hole 6 provides conditions for the through connection between positioning groove 3 and positioning block 5, and bolt 7 can thread the two together, allowing the gas composition sensor 4 to be fixed in the outer surface of the support frame 2. By installing the component for monitoring the gas composition when hot air is discharged from the engine room, the air composition inside the engine room can be detected, confirming the environmental conditions inside the engine room and ensuring the safety of crew members preparing to enter the engine room.
