Description

Technical Field

[0001] The present invention relates to the technical field of ship equipment, in particular to a structure of a shutter of a ship emergency generator. Background Art

[0002] With the rapid development of the shipbuilding industry, the volume of cargo transported by ships has also been increasing. Ship transport has the advantages of large transport volume and low freight. Ships are usually equipped with generator sets, which are used to supply electricity for the entire ship. The use of electricity is crucial for ships. In order to ensure the continuity of power on the ship, emergency generator sets are usually also installed. Both the generator set and the emergency generator set require sufficient ventilation to ensure their normal operation. Marine generators are installed in dedicated equipment compartments, and ventilation shutters are opened on the bulkheads;

[0003] Existing marine shutters usually only have multiple shutters that can be opened or closed at the same time in one shutter. This arrangement requires the entire shutter to be opened or closed at the same time when in use, so it is inconvenient to control the ventilation area and the opening size of the shutters during use. For generator sets, different ventilation parts require different air intake volumes. In the existing technology, the shutters only have two control states: open or closed, and the shutters cannot be controlled by area, which means that they cannot meet the usage requirements of ship owners.

[0004] Secondly, due to the limited size of the ship's cabin, the space inside the equipment compartment is relatively narrow when inspecting and servicing the generator, making it difficult to enter and exit the inspection area. This is especially true for the shutters on the generator ventilation system. Existing shutters are typically fixed shutters or shutters with openable and closed blades, but they still cannot meet the needs of generator maintenance or inspection. In view of the above, we propose a structure for marine emergency generator shutters to address the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned technical problems and to provide a structure of marine emergency generator shutters, which can conveniently control the opening and closing of the shutter blades, and can control the opening or closing of multiple shutters in different areas; and can also open the shutters as a whole to facilitate access to the shutter structure of the generator set maintenance area through the shutters.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a structure of a marine emergency generator shutter, comprising a frame and a plurality of shutters, the shutters being arranged in the frame, the shutters being able to form a plurality of partitioned shutters, and a driving mechanism being provided in the frame that can control the opening or closing of a single or multiple partitioned shutters at the same time.

The louvers in the same partitioned shutter are controlled to rotate synchronously by a connecting rod, and the connecting rod is hingedly connected to the rocker arm end of each louver.

[0008] Furthermore, a driving mechanism is provided between the two closest hinge shafts of adjacent partitioned blinds, and the driving mechanism also includes an adjusting button structure. The adjusting button structure is provided with a cam on one side of the frame, and the engagement or disengagement of each partitioned blind with the driving mechanism is controlled by the rotation of the cam.

[0009] Furthermore, the regulating knob structure is connected to one side outside the frame with a knob, and the rotation of the knob controls the rotation of the cam.

[0010] Furthermore, the adjusting button structure is provided with a motor driving structure in the frame for controlling the rotation of the cam.

[0011] Furthermore, a worm wheel is provided on each of the two closest hinge shafts, a worm is provided on one side of the worm wheel and meshed with the worm, and a bracket is provided in the frame to support the rotation of the worm.

[0012] Furthermore, the driving mechanism is also provided with a driving shaft, which is rotatably connected and arranged in the frame. The driving shaft and the two worms are transmitted by gears. A driving gear is provided on the driving shaft. The two worms are close to each other at one end and are respectively connected with worm shafts. The worm shafts are respectively slidably connected with driven gears. The rotation of the cam can push the driven gear on either side to slide on the worm shaft and disengage from the driving gear. A reduction motor connected to the driving shaft is also provided in the frame.

[0013] Furthermore, a return spring is wound around the worm shaft, one end of the return spring rests on the bracket, and the other end rests on the driven gear. The return spring pushes the driven gear to move and form an engagement with the driving gear; the side wall of the worm shaft is provided with a long keyway, and the inner wall of the driving gear is protruded with a convex key that matches the keyway.

[0014] Furthermore, a push piece is provided between the cam and the driving gear, the push piece is sleeved on the gear shaft, and the push piece is rotationally connected to the driven gear or the worm shaft.

[0015] Furthermore, it also includes a window frame, wherein the frame is arranged in the window frame and one side is hingedly connected to the frame.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0027] A structure of a shutter for a marine emergency generator, such as Figure 1 As shown, it includes a frame 1 and a plurality of louvers 2, the louvers 2 are arranged in the frame 1, and also includes a window frame 20, the window frame 20 is installed on the hull for fixing the structure of the entire shutter, the frame 1 is arranged in the window frame 20 and one side is hingedly connected to the frame 1, so that the window frame 20 forms a door structure that can be opened as a whole, thereby facilitating the opening of the entire shutter when repairing the generator set, and facilitating rapid access to the repair part of the generator set from the shutter part. Example 2:

[0028] In this embodiment, the entire shutter is divided into a plurality of partition shutters 3, and the opening position of the partition shutter 3 can be aligned with the specific part that needs ventilation. In actual implementation, the entire shutter structure is not limited to the longitudinal arrangement, but can also be arranged horizontally. Each partition shutter 3 is internally hinged with a plurality of shutter blades 2, and the plurality of shutter blades 2 can be opened or closed at the same time. Specifically, Figure 2 As shown, the hinge axes of the multiple louvers 2 hinged inside each partitioned louver 3 are arranged in parallel, and a rocker arm 4 is provided on the hinge axis at at least one end of the louver 2, which is driven by the rocker arm 4 to rotate. In order to enable the multiple louvers 2 to deflect at the same time, a connecting rod 5 is provided in the frame 1, and the connecting rod 5 is hingedly connected to the end of each rocker arm 4, thereby utilizing the deformation principle of the parallelogram to enable the various louvers 2 to deflect synchronously. Example 3:

[0029] This embodiment is provided with a driving mechanism to further improve the second embodiment, and to control the adjacent partitioned blinds 3 individually or synchronously, thereby achieving the effect of independent control or synchronous control of different air inlet positions; the driving mechanism is arranged in the frame 1 and is located between the two closest hinge shafts of the two adjacent partitioned blinds 3.

[0030] The driving mechanism can control the connection of each partition shutter 3 through the adjustment button structure, such as Figure 2 、 Figure 3 As shown, the adjustment knob structure is equipped with a cam 6 on one side of the frame 1. Rotation of the cam 6 controls the engagement or disengagement of each partitioned Venetian blind 3 with the drive mechanism. In actual use, one embodiment is to connect the adjustment knob structure to a knob 7 on the outside of the frame 1. Manual rotation of the knob 7 controls the rotation of the cam 6 to control the engagement of the partitioned Venetian blind 3. Another more automated embodiment can also be adopted, in which a motor drive structure is installed within the frame 1 to control the rotation of the cam 6. Using this motor drive structure to control the rotation of the cam 6 allows for remote control, increasing automation and reducing manual operation.

[0031] The driving mechanism drives the partition shutter 3 to operate based on the transmission principle of worm gear 8 and worm 9. A worm gear 8 is provided on each hinge shaft of the two closest shutter blades 2. A worm 9 is provided on one side of the worm gear 8 to engage with it. A bracket 10 is provided in the frame 1 to support the rotation of the worm 9. The worm 9 is rotatably arranged on the bracket 10. The worm gear 8 is driven by the worm 9 to rotate, thereby further driving the corresponding partition shutter 3 to realize the action, such as Figure 4As shown, two worms 9 are connected to each other at one end thereof and are provided with a worm shaft 13, and a driven gear 14 is slidably connected to the worm shaft 13. The side wall of the worm shaft 13 is provided with a long keyway 17, and the inner wall of the driving gear 12 is provided with a convex key 18 that matches the keyway 17. The inner convex key 18 of the driven gear 14 is snapped into the keyway 17, so that the driven gear 14 can rotate synchronously with the worm 9, and the driven gear 14 can move along the keyway 17. Figure 3 As shown, the cam 6 in the adjusting button structure drives the driven gear 14 to move, and the cam 6 rotates to push the driven gear 14 to slide along the axis of the worm gear 8 through the push plate.

[0032] The driving mechanism is further provided with a driving shaft 11, which is rotatably connected and arranged in the frame 1. The driving shaft 11 and the two worms 9 are driven by gears. A driving gear 12 is provided on the driving shaft 11. A reduction motor 15 connected to the driving shaft 11 is also provided in the frame 1. Figure 3 As shown, when the cam 6 rotates upward, it pushes the upper driven gear 14 to slide upward and disengage from the driving gear 12. At this time, the upper partition shutter 3 is disconnected from the driving mechanism. Similarly, when the cam 6 rotates downward, it can push the lower driven gear 14 out of the driving gear 12. At this time, the lower partition shutter 3 is out of the control of the driving mechanism. Figure 2 As shown, when the cam 6 is placed horizontally, the driven gears 14 on both sides can engage with the driving gear 12 at the same time, and at this time the partition shutters 3 on both sides can be controlled at the same time.

[0033] Furthermore, in order that the driven gear 14 can automatically mesh with the driving gear 12 after the cam 6 rotates, a return spring 16 is wound on the worm shaft 13, one end of the return spring 16 rests on the bracket 10, and the other end rests on the driven gear 14. When the cam 6 rotates away from the corresponding driven gear 14, the driven gear 14 is pushed down in the direction of the cam 6 under the action of the return spring 16 and gradually approaches the meshing driving gear 12; it can be understood that the driving gear 12 is driven by the reduction motor 15, which can achieve slow rotation, so the driving gear 12 and the driven gear 14 can be meshed under the action of the spring.

[0034] Furthermore, the aforementioned cam 6 does not directly push the driven gear 14 to move. Figure 3 As shown, a push piece 19 is provided between the cam 6 and the driving gear 12. The push piece 19 is sleeved on the gear shaft and does not rotate. Instead, the driven gear 14 or the worm shaft 13 rotates relative to the push piece 19. The cam 6 pushes the push piece 19 and indirectly pushes the driven gear 14 on this side. In order to reduce friction in actual use, a bearing can be provided between the push piece 19 and the driven gear 14.

[0035] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
