[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figure 1-6 shown

[0029] A ship fixed-pitch propeller control cabinet comprises a control box 1, which is hollow inside and provided with a tray 6 for placing a control component box and a battery; a filtering and heat dissipation component is located on both sides of the outside of the control box 1, and the filtering and heat dissipation component comprises a heat dissipation box 3 and a filter box 4, the heat dissipation box 3 and the filter box 4 are internally connected, and the heat dissipation box 3 is outside the filter box 4, and the inside of the filter box 4 is also connected to the inside of the control box 1. When the heat dissipation box 3 is working, gas can reach the inside of the control box 1 through the filter box 4.

[0030] like Figure 1 and Figure 4As shown, in this embodiment, two upper and lower fans 12 are arranged inside the heat dissipation box 3, and a protective net 13 is arranged at a corresponding position on the outer side of the fan 12 inside the heat dissipation box 3. The protective net 13 can protect the normal operation of the fan 12 and can also protect people's fingers from being accidentally injured by the fan 12. A hollow cavity 14 is provided inside the filter box 4, and a filter 20 can be placed in the hollow cavity 14. A slide 2 is arranged above the filter box 4. The slide 2 is convex in shape and can be slidably engaged above the filter box 4. The slide 2 can be pushed back and forth by the raised part at one end of the top of the slide 2. When the filter 20 needs to be replaced, the slide 2 can be pulled out, the filter box 4 can be opened, and the filter 20 can be taken out and replaced. After the replacement is completed, the slide 2 is pushed in to close the filter box 4.

[0031] like Figure 5 As shown, in this embodiment, the filter sheet 20 is composed of HEPA grade filter paper 17, activated carbon 18 and desiccant 19. HEPA grade filter paper 17: This filter material has a very high filtering accuracy and is mainly used to capture dust particles and various suspended substances in the air with a particle size of more than 0.5 microns. It is mainly made of ultra-fine glass fiber. For impurities with a particle size of more than 0.3 microns, the removal efficiency can also reach about 99%. The dust particles in the air move with the movement of the airflow. When encountering the HEPA grade filter paper 17 in the filter sheet 20, the airflow will pass through the filter paper, and the dust impurities will be intercepted by the filter paper. Activated carbon 18: It is a special filter material. Although the filtering accuracy is not very high, it can effectively absorb odors or harmful gases in the air. It is usually made of materials such as coconut shells, fruit shells or coal after high-temperature activation. After activation, a complex and dense pore structure will be formed inside the activated carbon material, so that it can obtain good adsorption capacity. The activated carbon 18 in the filter sheet 20 will firmly adsorb the harmful gas molecules in the air during the purification process, and then, under the attraction of the intermolecular force, more and more harmful gas molecules will enter the filter until the gap structure is filled. The activated carbon 18 can effectively remove high-concentration acids, alkalis and organic compound gases in the air and various harmful gases in the air. Filters 9 are set on both sides of the control box 1, and the positions of the filter 9 and the filter box 4 correspond.

[0032] In this embodiment, more uniform heat dissipation can be achieved through the upper and lower fans. When the gas passes through the filter box 4, the dust particles and various suspended substances in the air will be filtered out by the HEPA-grade filter paper 17 of the filter sheet 20, and then the harmful gases in the air will be filtered out by the activated carbon 18. Finally, the moisture in the air is absorbed by the desiccant 19 and then reaches the inside of the control box 1, thereby protecting the safety of the electronic components and circuits on the tray 6 and extending the service life.

[0033] like Figure 1 and Figure 6In this embodiment, pulley tracks 5 are respectively arranged on both sides of the control box 1, and pulleys 10 are respectively arranged at both ends of the tray 6. The pulleys 10 are slidably embedded in the pulley tracks 5, and the tray 6 can slide forward and backward along the pulley tracks 5. A blocking piece 15 is arranged on the left side of the front end of the tray 6, and the blocking piece 15 is fixed to the tray 6 through a connecting shaft 16, and the blocking piece 15 can rotate on the tray 6 through the connecting shaft 16.

[0034] In this embodiment, when the electronic components and circuits need to be repaired or maintained, the blocking piece 15 can be rotated to a position perpendicular to the tray 6, and the tray 6 can be pulled out along the pulley track 5 for repair or maintenance. After the repair is completed, the tray 6 can be pushed into the control box 1 along the pulley track 5, and then the blocking piece 15 can be rotated to insert the main part of the blocking piece 15 into the hollow position between the pulley track 5 and the front edge of the control box 1, which can limit the sliding of the tray 6 and fix it inside the control box 1.

[0035] like Figure 1 As shown, in this embodiment, four supporting legs 7 and a plurality of matching L-shaped fixing iron sheets 8 are arranged at the bottom end of the control box body 1, and a round hole 11 is arranged on the supporting leg 7. A screw is arranged at one end of the L-shaped fixing iron sheet 8, which can be inserted into the round hole 11 and fixed by a nut, and a hole can be punched at the other end of the L-shaped fixing iron sheet to fix it to the ground, so as to prevent the control cabinet from shifting due to the shaking of the ship. At the same time, the detachable setting also facilitates the replacement of the control cabinet at a later time.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
