Description

Technical Field

[0001] This utility model relates to the field of marine ventilation technology, and in particular to an intelligent ventilation and air exchange device for ships. Background Technology

[0002] Ship ventilation refers to a technical system that actively regulates the exchange of air between the interior and exterior of a ship's cabins through natural ventilation (ventilation ducts / skylights) or mechanical ventilation (fans / duct systems). Its core objective is to maintain the purity, temperature, humidity, and airflow rate of the air inside the cabins to ensure the safety and health of personnel, the normal operation of equipment, and the preservation quality of cargo.

[0003] Specialized filters are required for ventilation and air exchange on ships, but they need to be cleaned and replaced during use. In order to facilitate the replacement and cleaning of internal ventilation equipment, an intelligent ventilation and air exchange device for ships is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent ventilation and air exchange device for ships, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides an intelligent ventilation and air exchange device for ships, including an internal support frame, an outer shell installed on the outside of the internal support frame, three mounting frames and a fan installed sequentially inside the internal support frame, and three slots opened on the side of the outer shell near the mounting frames, with a closed plate installed inside the two slots near the fan.

[0006] Each of the three mounting frames has a fixed frame installed inside, and each of the three fixed frames has a filter screen installed inside near the fan. The mesh size of the three filter screens increases sequentially in the direction away from the fan.

[0007] The internal support frame is provided with a first fixed frame and a second fixed frame on the side away from the fan. An electric push rod is installed on one side of the bottom end of the first fixed frame, and a sealing plate is installed at its output end. The sealing plate is fixedly connected to the fixed frame. Guide rails are installed on the top and bottom surfaces of the inner wall of the second fixed frame, and the positions of the two guide rails are aligned with a slot.

[0008] Preferably, in any of the above solutions, an electric regulating valve is installed at the end of the outer casing near the fan, an air quality sensor is installed on the top wall of the outer casing near the fan, and a control module is installed at one corner of the outer wall of the outer casing. This solution achieves precise control of the air volume by changing the valve opening. It also employs a motor and reverse control for opening and closing, resulting in rapid action and facilitating automated control. The control module is a PLC, electrically connected to the air quality sensor. The air quality sensor detects the input air quality and outputs a digital signal, which is directly transmitted to the control module. The PLC's internal microcontroller processes the data to identify the air quality and control the extension or retraction of the electric actuator.

[0009] Preferably, as described in any of the above schemes, three maintenance channels are installed on the bottom surface of the outer casing near the mounting frame plate, and a base plate is installed at the bottom end of each of the three maintenance channels. This scheme facilitates the removal of the base plate, allowing operators to enter the interior of the outer casing along the maintenance channels to clean the surfaces of the three filters, thus maintaining good air permeability of the filters.

[0010] Preferably, both ends of the two sealing plates are fixedly connected to the outer shell by fasteners, and the sides of the two sealing plates press against the sides of the fixing frame. This design makes the two sealing plates easy to disassemble. When the filter screen is replaced, the two sealing plates can be disassembled to remove the fixing frame and replace the filter screen.

[0011] Preferably, in any of the above solutions, a groove is provided in the middle of the outer wall of the three fixed frames, and a sealing gasket is installed inside the groove. A square frame is installed on the inner wall of the three fixed frames to press the filter screen. This solution can improve the sealing between the three fixed frames and the mounting frame plate, avoid air leakage, and ensure stability during the entire air intake process. The square frame is fixedly connected to the inner wall of the fixed frame by bolts, which facilitates pressing the edge of the filter screen.

[0012] Preferably, the top of the first fixing frame and the side of the second fixing frame are fixedly connected to the external vessel by welding. This method facilitates the fixed connection of the first and second fixing frames to the external vessel, thereby providing installation positions for the electric push rod and the two guide rails, and limiting and guiding the horizontal sliding of a fixing frame.

[0013] This utility model has the following advantages:

[0014] 1. This intelligent ventilation and air exchange device for ships consists of three outer shells with three maintenance channels on their bottom surfaces. By disassembling the bottom plates of the three maintenance channels, operators can enter the interior of the outer shells to facilitate cleaning of the filter screens. An internal support frame is provided with three mounting frame plates to provide installation positions for the fixed frames. The fixed frames are pressed together by sealing plates and blocking plates. The sealing plates and blocking plates can then be disassembled to facilitate the removal of the mounting frames and replacement of the filter screens. The overall structure is simple, the design is reasonable, and it is easy to promote and use.

[0015] 2. This intelligent ventilation and air exchange device for ships is equipped with an electric push rod and two guide rails aligned with a slot. A control module and an air quality sensor are installed on the outer casing. The air quality sensor measures the quality of the incoming air. The control module controls the electric push rod to shorten, pulling out a fixed frame. When the air quality is low, the electric push rod drags the fixed frame into the mounting plate. When the air quality is good, the electric push rod slides the fixed frame out of the mounting plate, reducing obstruction to airflow and thus reducing energy consumption.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0025] like Figures 1 to 7 As shown, a ship intelligent ventilation and air exchange device includes an internal support frame 1, an outer shell 13 is installed on the outside of the internal support frame 1, three mounting frames 14 and a fan 12 are installed in sequence inside the internal support frame 1, and three slots 18 are opened on the side of the outer shell 13 near the mounting frames 14, and a sealing plate 10 is provided in the two slots 18 near the fan 12.

[0026] Each of the three mounting frames 14 has a fixed frame 11 installed inside. Each of the three fixed frames 11 near the fan 12 has a filter screen 17 installed inside. The mesh count of the three filter screens 17 increases sequentially in the direction away from the fan 12. Since the mesh count of the three filter screens 17 increases sequentially, it is convenient to perform three-stage filtration of the air and improve the cleanliness of the incoming air. In addition, when the incoming air quality is good, the electric push rod 7 drives the filter screen 17 with the highest mesh count to be pulled out, which facilitates air circulation and reduces wind resistance and power consumption of the fan 12.

[0027] The internal support frame 1 is provided with a first fixed frame 8 and a second fixed frame 6 on the side away from the fan 12. An electric push rod 7 is installed on one side of the bottom end of the first fixed frame 8, and a sealing plate 9 is installed at its output end. The sealing plate 9 is fixedly connected to the fixed frame 11. Guide rails 5 are installed on the top and bottom surfaces of the inner wall of the second fixed frame 6. The positions of the two guide rails 5 are aligned with a slot 18.

[0028] An electric regulating valve 2 is installed at one end of the outer casing 13 near the fan 12, and an air quality sensor 15 is installed on the top wall of the outer casing 13 near the fan 12. A control module 16 is installed at one corner of the outer wall of the outer casing 13. As an optional technical solution of this utility model, one end of the electric regulating valve 2 is fixedly connected to the end of the inner support frame 1 by fasteners. The electric regulating valve 2 facilitates the control of the incoming air and is a device for regulating the airflow. It achieves precise control of the air volume by changing the valve opening. At the same time, it adopts a motor and reverse control for opening and closing, and its action is rapid, which is convenient for automated control. The control module 16 is a PLC, which is electrically connected to the air quality sensor 15. The air quality sensor 15 is used to detect the input air quality and output digital signals, which are directly transmitted to the control module 16. The microcontroller inside the PLC performs calculations and processing to identify the air quality and control the extension or retraction of the electric push rod 7.

[0029] Three maintenance channels 3 are installed on the bottom surface of the outer casing 13 near the mounting frame plate 14. Each of the three maintenance channels 3 has a base plate 4 installed at its bottom end. As an optional technical solution of this utility model, this makes it easy for the operator to enter the interior of the outer casing 13 along the maintenance channel 3 after the base plate 4 is removed, and to clean the surface of the three filter screens 17 so that the filter screens 17 maintain good air permeability.

[0030] Both ends of the two sealing plates 10 are fixedly connected to the outer shell 13 by fasteners. The sides of the two sealing plates 10 press against the sides of the fixing frame 11. As an optional technical solution of this utility model, this makes the two sealing plates 10 easy to disassemble. When the filter screen 17 is replaced, the two sealing plates 10 can be disassembled to facilitate the removal of the fixing frame 11 and the replacement of the filter screen 17.

[0031] The outer walls of the three fixed frames 11 are provided with grooves in the middle, and sealing gaskets 20 are installed inside the grooves. The inner walls of the three fixed frames 11 are provided with square frames 19 to press the filter screen 17. As an optional technical solution of this utility model, this facilitates the improvement of the sealing between the three fixed frames 11 and the mounting frame plate 14, avoids air leakage, and ensures stability during the entire air intake process. The square frames 19 are fixedly connected to the inner walls of the fixed frames 11 by bolts, which facilitates the pressing of the edge of the filter screen 17.

[0032] The top of the first fixed frame 8 and the side of the second fixed frame 6 are fixedly connected to the external vessel by welding. As an optional technical solution of this utility model, this facilitates the fixed connection of the first fixed frame 8 and the second fixed frame 6 to the external vessel, thereby providing an installation position for the electric push rod 7 and the two guide rails 5, and then limiting and guiding the horizontal sliding of a fixed frame 11.

[0033] This intelligent ventilation and air exchange device for ships requires the following steps to be used:

[0034] 1) During disassembly, the electric push rod 7 shortens, causing a fixed frame 11 to slide out of the mounting frame plate 14;

[0035] 2) Remove the closing plate 10 to facilitate the pulling out of the other two fixing frames 11;

[0036] 3) Remove the base plate 4 to allow operators to enter the interior of the outer casing 13 and clean the filter screens 17 on the three fixed frames 11.

[0037] In summary, during use, the system features three outer casings 13 with three maintenance channels 3 on their bottom surfaces. The bottom plates 4 at the bottom of these channels 3 are disassembled, allowing operators to enter the interior of the casings 13 for easy cleaning of the filter screen 17. An internal support frame 1 with three mounting plates 14 provides mounting positions for the fixed frame 11. The fixed frame 11 is then secured by a sealing plate 10 and a blocking plate 9. Disassembling the sealing plate 10 and blocking plate 9 allows for easy removal of the mounting frame 14 and replacement of the filter screen 17. The overall structure is simple, rationally designed, and easy to operate. For wider application, an electric push rod 7 and two guide rails 5 are set up, with the two guide rails 5 aligned with a slot 18. At the same time, a control module 16 and an air quality sensor 15 are installed on the outer casing 13. The air quality sensor 15 can easily measure the quality of the incoming air. Meanwhile, the control module 16 controls the electric push rod 7 to shorten, pulling out a fixed frame 11. When the air quality is low, the electric push rod 7 drags the fixed frame 11 into the interior of the mounting frame plate 14. When the air quality is good, the electric push rod 7 drives the fixed frame 11 at the tail end to slide out of the mounting frame plate 14, reducing the obstruction to airflow and relatively reducing energy consumption.
