Description

Technical Field

[0001] This utility model relates to a marine air conditioning device, specifically a marine explosion-proof mobile air conditioning device. Background Technology

[0002] With the continuous development of the shipbuilding industry and the commissioning of various types of ships, the requirements for the comfort of personnel in explosion-proof areas are becoming increasingly stringent. Temporary work and construction are often required in these areas, necessitating the provision of a suitable working temperature. Explosion-proof areas typically avoid the installation of fixed air conditioning units, instead using temporary portable air conditioners when necessary. Existing portable air conditioner structures mostly involve directly mounting casters on the lower part of the fixed air conditioning unit for easy movement. However, issues regarding their installation in explosion-proof areas, their explosion-proof performance requirements, rapid connection of air supply, and safe storage on ships have not yet been adequately addressed. Summary of the Invention

[0003] This utility model provides a marine explosion-proof mobile air conditioning device with a simple structure, easy to adapt to explosion-proof areas, convenient to use, and safe and stable for storage and use.

[0004] The technical solution adopted by this utility model is: a marine explosion-proof mobile air conditioning device, including a box with brake rollers at the bottom, the box adopting a frame structure with panels covering all four sides, characterized in that: an air outlet is provided on the upper left side of the front side of the box, the air outlet is connected to an air outlet flange, a fresh air inlet with a grille or louvered damper is provided on the upper right side of the front side of the box, the fresh air inlet is equipped with a pre-filter and a high-efficiency filter, an evaporator is provided in the inner cavity of the right side of the box, a blower is provided between the evaporator and the air outlet, and a blower is provided in the lower left side of the box. The cavity houses a compressor refrigeration unit connected to the evaporator. An explosion-proof wiring control box is located on the lower right rear of the enclosure. The explosion-proof wiring control box contains a controller and a cable reel. The cable reel extends from the explosion-proof wiring control box toward the lower part of the enclosure. Mounting holes are provided on both sides of the frame at the four corners of the enclosure. Connecting seats are bolted to the mounting holes. Pull-out holes are provided on the connecting seats. The pull-out holes are connected to the hook at the ship's usage location via the locking buckles at both ends of the tension rope, or the pull-out holes are connected to the bulkhead at the ship's storage location via a pull-out rod.

[0005] Handrails are provided on the upper part of both the left and right sides of the box.

[0006] The air outlet flange is sealed with bolts, or the air duct with an adjustable aperture damper is locked in place, or the air duct is connected by clamps.

[0007] The air duct is a flexible air duct.

[0008] The latch is a screw thread, shackle, or hook.

[0009] The connecting rod is folded and fitted to the cabin wall and then tightened with bolts.

[0010] The beneficial effects of this utility model are:

[0011] 1. The cable is released downwards from the cable reel in the lower explosion-proof wiring control box. Combined with the controller being installed inside the explosion-proof wiring control box, this effectively improves the safety of cable laying and the electrical explosion-proof performance of the air conditioning unit.

[0012] 2. The air outlet adopts an air outlet flange that can be quickly adapted to an adjustable aperture damper, and can directly supply air to the environment that needs air supply through the air duct. The connection is quick and the air supply is stable and adjustable.

[0013] 3. Mounting holes are provided on both sides of the frame corners, and bolts can be used to lock the connecting seats on either side. When it is necessary to fix the unit in use, the connecting seats on the left and right sides of the frame are symmetrically set. The ground hook is pulled through the locking buckle and tightening rope through the pull hole on the symmetrical connecting seat, which can effectively achieve the fixed positioning of the unit in use and ensure the stable use of the air conditioner.

[0014] 4. When storage is required, the front side of the frame should be fitted with the bulkhead. Connect the connecting seat to the mounting holes on the two frames on the front side of the frame. Lock the connecting rod on the connecting seat and lock the connecting rod to the bulkhead to effectively achieve fixed positioning in the storage location and ensure safe storage of the air-conditioned temperature.

[0021] The following explanation, in conjunction with the accompanying drawings, will provide further details.

[0022] The housing 1 adopts a frame 4 with a panel covering all four sides. An air outlet 12 is set on the upper left side of the front side of the housing 1. An air outlet flange 14 is connected to the air outlet 12. The air outlet flange is sealed with bolts, or connected to an air duct with an adjustable aperture damper, or connected to an air duct with clamps.

[0023] A marine explosion-proof mobile air conditioning unit has a fresh air inlet 14 with a grille or louvered damper on the right side of the front side of the housing 1. The fresh air inlet 14 is equipped with a pre-filter and a high-efficiency filter. An evaporator 15 is installed in the inner cavity on the right side of the housing. A blower 16 is installed between the evaporator and the air outlet 12. A compressor refrigeration unit 17 connected to the evaporator is installed in the lower inner cavity on the left side of the housing 1. An explosion-proof wiring control box 18 is installed in the lower rear right side of the housing. The explosion-proof wiring control box 18 contains a controller 19 and a cable reel 20. The cable reel 20 extends the cable 21 from the explosion-proof wiring control box toward the lower part of the housing 1. Mounting holes 5 are provided on both sides of the frame 4 at the four corners of the housing 1. The mounting holes 5 are bolted to the connecting seats 6. The connecting seats 6 are provided with pull holes 7. The pull holes 7 are connected to the ground hook 9 at the ship's usage position by the locking buckles at both ends of the tension rope 8. The pull fixing direction can be adjusted as needed on the two relatively vertical sides of the frame side.

[0024] When this device is stored, it is fixed to the corresponding flat bulkhead 22. The mounting base 6 is connected to the flat bulkhead via the connecting rod 10 through the connecting hole 7 and is locked to the flat bulkhead at the storage location of the ship via the folded edge 11.

[0025] When this device is stored, it is fixed to the corner bulkhead 23. The mounting base on the side of the box 1 corresponding to the two bulkhead planes of the corner bulkhead 23 can be selected. The mounting base 6 is pulled through the connecting hole 7 and the connecting rod 10 is pulled towards the bulkhead of the corner bulkhead. The device is then locked and pulled to the corner bulkhead of the ship's storage position through the folded edge 11.

[0026] In this embodiment, the duct can be a flexible duct.

[0027] In this embodiment, the latch is a screw thread, shackle, or hook.
