[0002] Marine air conditioning systems are mainly used for air treatment in summer and winter, providing cabins with air of a certain temperature, humidity and cleanliness. For working cabins equipped with equipment with large heat dissipation, auxiliary air conditioning equipment will be added.

[0003] Traditional noise reduction equipment for marine air conditioners often covers the air conditioning components through the air conditioning cabinet to reduce the noise generated when the air conditioner is running. In this method, the noise reduction means are single, it is difficult to eliminate noise in a targeted manner, and it is difficult to cope with the complex arrangement of components in the marine air conditioning cabinet. Summary of the invention

[0004] The present invention mainly provides a noise reduction device for a marine air conditioner to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A noise reduction device for a marine air conditioner comprises a support frame, side walls are connected to both sides of the support frame, a sealing plate is connected to the top and bottom of the support frame, and a noise reduction mechanism is connected to the surface of one side of the side walls close to each other;

[0007] The noise reduction mechanism includes a plurality of telescopic sound-absorbing columns connected to a side surface of the side wall close to each other, and a sound wave noise reduction component connected to the telescopic sound-absorbing columns;

[0008] The top end of the inner surface of the side wall is connected with an extrusion component, and the extrusion component is connected to an adjacent telescopic sound-absorbing column.

[0009] Furthermore, sealing plates are connected to the front and rear sides of the support frame, and the sealing plates, side walls and inner surfaces of the sealing plates are all connected to sound-absorbing cotton boards. In the present invention, the opening of the support frame is sealed by the sealing plate, and the noise generated by the air-conditioning elements in the support frame is reduced by the provision of the sound-absorbing cotton board.

[0010] Furthermore, the telescopic sound-absorbing column includes a guide straight rod connected to a side surface of the side wall, and a sliding sleeve sleeve mounted on the outer surface of the guide straight rod. In the present invention, the guide straight rod provides a guide for the sliding of the sliding sleeve so that the sliding sleeve slides along a straight line. In this way, the telescopic sound-absorbing column can be stably raised and lowered.

[0011] Furthermore, one end of the guide straight rod is plugged into the sound-absorbing cotton board, a spring is sleeved on the outside of the guide straight rod, one end of the spring abuts against the sound-absorbing cotton board, and one end of the spring abuts against one side surface of the sliding sleeve. In the present invention, a groove is formed by the automatically extended telescopic sound-absorbing column and the shortened telescopic sound-absorbing column due to extrusion, so that the sound wave noise reduction component can be accommodated through the groove.

[0012] Furthermore, the outer sleeve of the sliding sleeve is provided with an attractive cotton sleeve, and when the telescopic sound-absorbing column is shortened, the telescopic sound-absorbing column forms a groove for inserting the sound wave noise reduction component.

In the present invention, the sound wave noise reduction assembly is clamped by a tightened groove, and in this way, the position of the sound wave noise reduction assembly can be adjusted arbitrarily, so that the sound wave noise reduction assembly can be close to the air-conditioning element that generates noise to reduce noise.

[0015] Furthermore, first dimensional grooves are provided at both ends of the surface of the side wall close to the telescopic sound-absorbing column, and the two first dimensional grooves are symmetrically arranged on both sides of the telescopic sound-absorbing column. In the present invention, the first dimensional groove is arranged on the side wall to facilitate the adjustment of the sound wave noise reduction component through the first dimensional groove in combination with the second dimensional groove.

[0016] Furthermore, the support frame includes a connecting frame connected to the side surface of the two sealing plates close to each other, and a plurality of columns connecting the two connecting frames, wherein the plurality of columns are located at a plurality of top corners of the connecting frame, and a second dimensional groove is provided on the outer surface of the column.

[0017] Furthermore, a plurality of heat dissipation holes are provided on one side of the sealing plate, and the plurality of heat dissipation holes are arranged in an array. In the present invention, the heat dissipation of the internal components of the air conditioner is accelerated by the arrangement of the heat dissipation holes.

[0018] Furthermore, a plurality of clamping rods are provided at the upper and lower ends of the support frame, and the longitudinal section of the clamping rods is L-shaped. The clamping rods are connected to the inner surfaces of adjacent connecting frames. In the present invention, the clamping rods cooperate with the grooves formed by the telescopic sound-absorbing columns to facilitate the installation and disassembly of the side walls and the sealing plates, thereby facilitating the opening of the cabinet and the disassembly of the air-conditioning components.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Firstly, the present invention collects the noise generated by the nearby air-conditioning components through a noise collecting device, and generates a noise reduction wave that cancels the noise signal, and plays the noise reduction wave through a speaker connected to the noise collecting device, so as to cancel the noise generated by the air-conditioning components in this way.

[0021] Secondly, the present invention drives an extrusion plate through an electric telescopic rod to extrude a plurality of telescopic sound-absorbing columns through the extrusion plate, thereby tightening the grooves formed by the plurality of telescopic sound-absorbing columns, so as to clamp the sound wave noise reduction component through the tightened grooves, and in this way, the position of the sound wave noise reduction component can be arbitrarily adjusted, so that the sound wave noise reduction component can be close to the air-conditioning element that generates noise to reduce noise.
