DETAILED DESCRIPTION

[0023] The application will be described in further detail below with reference to the drawings. It is necessary to point out here that the following detailed description is only used to further illustrate the application and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0024] Referring to Figure 1 and Figure 2 A multifunctional control box for a marine diesel engine turning gear, comprising a box 1 and a heat dissipation opening provided on one side of the box 1, wherein the heat dissipation opening is provided with an installation cylinder 2, the installation cylinder 2 is provided with a filter plate 3, the control box further comprises a dust cleaning assembly 4 for driving the filter plate 3 to vibrate by ship sway so that dust adhering to the filter surface of the filter plate 3 falls off, and the installation cylinder 2 is further provided with an air supply assembly 5 linked with the dust cleaning assembly 4 to supply air into the box 1 to promote heat dissipation.

[0025] The dust cleaning assembly 4 drives the filter plate 3 to vibrate by ship sway so that dust adhering to the filter surface of the filter plate 3 falls off, achieving the cleaning effect of the filter plate 3 without manual intervention, so that the filter plate 3 can be kept unobstructed for a long time, ensuring the heat dissipation requirement of the control box; the air supply assembly 5 and the dust cleaning assembly 4 are in linkage (i.e. by ship sway again), and the air supply assembly 5 supplies air into the box 1 to promote heat dissipation. The control box has the functions of automatic cleaning of the filter plate 3 and air supply into the box 1 to promote heat dissipation, which is convenient and time-saving in practical application.

[0026] Referring to Figures 1 to 6In one embodiment of the present invention, the dust removal assembly 4 includes a linkage 401 reciprocatingly disposed in the mounting cylinder 2 and an abutment 411 hinged to the filter plate 3 and capable of deflecting at a certain angle (the abutment 411 being capable of deflecting at a certain angle means, taking the perpendicularity between the abutment 411 and the filter plate 3 as an example, the abutment 411 can only deflect at a certain angle up and down, such as 30°, 40°, etc.). The filter plate 3 is provided with limiting measures corresponding to the abutment 411. The limiting measures can be using a hinge of a specific angle, or by setting a limiting boss to block the abutment 411, etc. In this embodiment, (Not limited), the linkage 401 is provided with a column 413 for abutting against the contacting member 411, the mounting cylinder 2 is symmetrically provided with a plurality of protrusions 415, the filter plate 3 is provided with a column 417 corresponding to the protrusion 415, the column 417 slides through the corresponding protrusion 415, and the end of the column 417 away from the filter plate 3 is provided with a stop block 418, and an elastic member 416 is sleeved on the column section of the column 417 located between the filter plate 3 and the protrusion 415. Preferably, the elastic member 416 is a spring. The dust removal assembly 4 also includes a driving component that uses the rocking of the ship to drive the linkage 401 to move back and forth. The driving component includes a cylinder 404 mounted on the housing 1 and a boom 405 ball-hinged in the cylinder 404. The lower end of the boom 405 is provided with a counterweight ball 408. A slide block 406 is also slidably mounted in the cylinder 404, and a conical groove 407 is provided on the slide block 406. The counterweight ball 408 is located in the conical groove 407. A driving rod 403 is also hinged on the housing 1. The linkage 401 slides through one side of the mounting cylinder 2, and a follower block 402 is hinged to the part of the linkage 401 outside the mounting cylinder 2. One end of the driving rod 403 abuts against the bottom side of the slide block 406, and the other end moves through the follower block 402. A first torsion spring 410 is provided at the hinge point between the driving rod 403 and the housing 1 to drive the driving rod 403 to reset (i.e., to cause the end of the driving rod 403 that abuts against the bottom side of the slide block 406 to tilt upward).

[0027] In this embodiment, when the ship rocks, the counterweight ball 408 will oscillate back and forth under its own weight, thus intermittently contacting the wall of the conical groove 407. During the stroke of the counterweight ball 408 in contact with the wall of the conical groove 407, the weight and impact force of the counterweight ball 408 drive the slide block 406 to slide downward (i.e., towards the bottom of the cylinder 404). The downward movement of the slide block 406 causes the end of the drive rod 403 that passes through the follower block 402 to tilt upward, driving the linkage 401 to move upward (to... Figure 2(Explained by the angle shown) During the stroke when the counterweight ball 408 does not contact the wall of the conical groove 407, the drive rod 403 is reset under the action of the first torsion spring 410, which causes the linkage 401 to move down. This cycle is repeated to realize the reciprocating movement of the linkage 401. During the reciprocating movement of the column 413, the end of the column 413 contacts the contacting member 411 and drives it to deflect upward or downward until it reaches the set limit angle. When the contacting member 411 reaches the set limit angle, the column 413 will press against the contacting member 411, causing the filter plate 3 to move away from the linkage 401. During this process, several elastic members 416 are compressed and stored. When the column 413 (end) is separated from the contacting member 411, the filter plate 3 is instantly reset under the action of several elastic members 416, thereby generating vibration. Through the vibration, the dirt on the filter surface of the filter plate 3 is dislodged, achieving the effect of cleaning the filter plate 3.

[0028] Furthermore, in this embodiment, a first roller 409 is provided at the end of the drive rod 403 that abuts against the bottom side of the slide block 406. By providing the first roller 409, the relative movement between the end of the drive rod 403 and the bottom side of the slide block 406 is smoother (sliding friction is converted into rolling friction). A second torsion spring 412 is provided at the hinge point between the contact member 411 and the filter plate 3. In its natural state, the contact member 411 is perpendicular to the filter plate 3. A second roller 414 is also provided at the end of the column 413 that abuts against the contact member 411. By providing the second roller 414, the movement between the end of the column 413 and the contact member 411 is smoother.

[0029] Furthermore, in this embodiment, a dust guide plate 6 is also obliquely provided on the lower side of the filter plate 3 to guide the shaken-off dust and dirt outward.

[0030] Furthermore, in this embodiment, the mounting cylinder 2 is provided with a rubber gasket to keep the side of the filter plate 3 sealed with the inner wall of the mounting cylinder 2, so as to prevent external airflow containing dust and dirt from entering the box 1 through the gap between the side of the filter plate 3 and the inner wall of the mounting cylinder 2.

[0031] Please see Figure 2 and Figure 6In one embodiment of the present invention, the air supply assembly 5 includes two symmetrically arranged air chambers 501 in the mounting cylinder 2. The air chamber 501 is provided with a piston plate 502 (the piston plate 502 and the cavity wall of the air chamber 501 are in a sealed state, such as by setting a sealing rubber ring, which is equivalent to a sealed piston). A plurality of air outlet pipes 503 are arranged on the air chamber 501, which are directed to the inside of the housing 1. The air outlet pipes 503 are provided with a first one-way valve 504 that only allows the airflow in the air chamber 501 to be discharged. The air chamber 501 is also provided with an air inlet 505. A second one-way valve 506 that only allows external airflow to enter the air chamber 501 is provided at the air inlet 505. The air supply assembly 5 also includes a T-shaped rod 507 provided on the linkage member 401. The two ends of the T-shaped rod 507 away from the linkage member 401 are respectively connected to the two piston plates 502.

[0032] In this embodiment, the reciprocating movement of the linkage 401 drives the T-shaped rod 507 to move accordingly, so that the two piston plates 502 reciprocate in the corresponding air chambers 501 respectively, performing exhaust and suction actions respectively, and exhausting air into the housing 1 through several air outlet pipes 503, promoting airflow in the housing 1, thereby improving the heat dissipation effect of the control box.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
