Description

TECHNICAL FIELD

[0001] The present application relates to the field of searchlight technology, in particular to an electric remote high-definition searchlight for a ship. BACKGROUND

[0002] Remote high-definition searchlight is a key active visual equipment for ship navigation or operation under night or low-visibility conditions, and its lighting effect directly affects the safety of ship control and the efficiency of operation. Compared with single-head searchlight, double-head searchlight can significantly weaken or eliminate the shadow behind the target by simultaneously irradiating the target area from two relatively symmetrical directions, so as to make the illuminated object present clearer, three-dimensional and complete image information, and still maintain basic lighting ability when one of the lamp heads fails, thereby improving the reliability and continuous operation ability of the searchlight system. Therefore, the double-lamp head structure has gradually become one of the important development directions of ship searchlight.

[0003] In the practical application of double-lamp head searchlight, in order to ensure that the irradiation areas of the two lamp heads always remain consistent, the synchronization of the luffing operation is a key technical prerequisite for realizing the above lighting effect and system usability. Once there is a deviation in the luffing angle between the two lamp heads, not only the effect of bidirectional irradiation to eliminate the shadow will be weakened, but also new uneven brightness may be generated in the target area, which affects the camera imaging quality and even reduces the judgment ability of the operator or automatic control system.

[0004] In view of the foregoing problems, the prior art usually adopts the common shaft driving mode, that is, the same shaft drives the synchronous luffing rotation of the two lamp heads. However, since the two lamp heads are installed on the same shaft, the shaft and its driving parts not only need to bear the superimposed weight of the two lamp heads, but also need to resist the additional load brought by the external environment such as wind and wave. During the process of upward rotation of the lamp heads, the shaft and its driving parts need to overcome the action of gravity and external environment to drive the lamp heads to rotate upward, which will seriously increase the mechanical loss of the shaft and its driving parts, thereby reducing the stability of luffing adjustment and shortening its service life. In addition, in the static state of non-luffing adjustment, the luffing support point of the existing double-lamp head searchlight usually depends on a single rotary support point, which will also accelerate the mechanical wear under the influence of gravity and external environment such as wind and wave for a long time, thereby affecting the stability of the luffing adjustment process and the service life of the mechanical parts.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Please see Figure 1 , Figure 2 and Figure 3 A marine electric long-range high-definition searchlight includes a horizontal rotating base 1, a lamp head 2, a clamping head 4, an assist structure 5, a conversion structure 6, and a base 8.

[0023] The lamp heads 2 are symmetrically distributed on the left and right sides and are mounted on the horizontal rotating base 1 in a tilting and rotating manner. Both lamp heads 2 are simultaneously mounted on the same rotating shaft, which is driven by a drive component to achieve synchronous tilting and rotating of the two lamp heads 2. The horizontal rotating base 1 is rotatably mounted on the base 8. A camera 9 is positioned between the symmetrical lamp heads 2 and is fixedly mounted on the horizontal rotating base 1. Supporting components 3 are fixedly mounted on both lamp heads 2, and these components rotate with the tilting and rotating motion of the lamp heads 2.

[0024] The drive component one (not shown in the figure) of the rotating shaft includes a motor, a worm gear, and a worm wheel. The motor drives the worm gear, which in turn drives the worm wheel, which is fixedly connected to the rotating shaft, to rotate, thus achieving the rotation of the rotating shaft. Similarly, the rotation of the horizontal rotating seat 1 is achieved by drive component two (not shown in the figure). The motor in drive component two drives the worm gear, which in turn drives the rotary worm wheel, which is fixedly connected to the horizontal rotating seat 1. It should be noted that drive component one is installed as a whole in the internal cavity of the horizontal rotating seat 1, while drive component two is installed in the internal cavity of the base 8. This is to isolate the high-salt, high-humidity air and possible splash water from the ship's environment, thereby improving the stability and service life of the drive system.

[0025] See Figure 2 and Figure 3The assist structure 5 provides an upward auxiliary thrust to the lamp head 2 through the support member 3, assisting the lamp head 2 to rotate upward, thereby reducing the load on the rotating shaft and drive component 1. The clamping head 4 corresponds one-to-one with the support member 3 and is used to clamp and fix the corresponding support member 3 (such as...). Figure 2 As shown, the lamp head 2 provides an additional support point when stationary, thereby improving the stability of the lamp head 2. The conversion structure 6 is located between the clamping head 4 and the assist structure 5, and is used to control the clamping or releasing state of the clamping head 4 in conjunction with the operation of the assist structure 5, so as to realize the integration of functions and the simplification of the drive system.

[0026] The specific working process is as follows: 1. Static state.

[0027] When the lamp head 2 is stationary, the clamping head 4 clamps and fixes the corresponding support component 3, providing an additional support point for the lamp head 2, improving the stability of the lamp head 2 in strong wind and wave environments, and reducing the mechanical wear caused by external environmental factors such as gravity and wind and wave loads on the rotating shaft and drive components.

[0028] 2. Adjust the pitch upwards.

[0029] Just before the lamp head 2 is about to rotate from bottom to top, the assist structure 5 begins to store auxiliary thrust and drives the corresponding clamping head 4 to release the support member 3 through the conversion structure 6. Subsequently, the lamp head 2 rotates upward, and at the same time, the assist structure 5 releases the stored auxiliary thrust and acts on the support member 3 to assist the lamp head 2 in rotating upward, thereby reducing the load on the shaft and the first drive component, improving the stability of the lamp head 2 in the upward rotation process and reducing the mechanical wear of the shaft and the first drive component.

[0030] When the lamp head 2 stops rotating, the assist structure 5 resets and drives the corresponding clamping head 4 to clamp and fix the corresponding support component 3 again through the conversion structure 6.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The assist structure 5 includes a drive assembly 51, an assist head 52, a receiving joint 53, and an elastic component 54. The receiving joints 53 are fixedly installed on the support member 3, the assist heads 52 are respectively arranged corresponding to the receiving joints 53, and the two form a wedge fit. The elastic components 54 are respectively disposed between the assist head 52 and the drive assembly 51.

[0032] The drive assembly 51 includes a translation shaft 511 and a bidirectional screw 512. The translation shaft 511 is symmetrically distributed on the left and right sides. The two threaded areas of the bidirectional screw 512 with opposite thread directions respectively mesh with the translation shaft 511. By rotating the bidirectional screw 512, the symmetrical translation shaft 511 is controlled to move synchronously in opposite directions.

[0033] like Figure 3 As shown, the left translation axis 511 moves leftward via the corresponding elastic component 54, causing the left assist head 52 to move leftward and abut against the left bearing joint 53. Then, the translation axis 511 continues to move leftward, the left assist head 52 stops moving, and the corresponding elastic component 54 undergoes elastic deformation and stores auxiliary thrust. Simultaneously, the right translation axis 511 moves rightward via the corresponding elastic component 54, causing the right assist head 52 to move rightward and abut against the right bearing joint 53. Then, the translation axis 511 continues to move rightward, the right assist head 52 stops moving, and the corresponding elastic component 54 undergoes elastic deformation and stores auxiliary thrust. When the lamp head 2 rotates upward, the elastic component 54 releases the stored auxiliary thrust to assist the lamp head 2 in rotating upward.

[0034] The rotation of the bidirectional screw 512 is achieved through the drive component three. The motor in the drive component three drives the worm gear, which in turn drives the turbine gear that is fixedly connected to the bidirectional screw 512.

[0035] The specific process of realizing the assistive effect: combining Figure 2 , Figure 5 and Figure 6 As shown, the assist head 52 has an overall arc-shaped structure and is inclined to the axial surface of the corresponding connector 53. When the assist head 52 abuts against the corresponding connector 53, its inclined axial surface contacts the connector 53. At this time, as the translation shaft 511 continues to move, the corresponding elastic component 54 begins to compress and store elastic potential energy to assist the lamp head 2 to move upward.

[0036] When the receiving joint 53 rotates upward along with the supporting member 3 and the lamp head 2, the elastic component 54 releases the stored elastic potential energy, causing the assist head 52 to continue moving in the original direction. This continuously applies an assisting thrust to the lamp head 2 through the inclined axial surface, thus assisting its upward rotation. It should be noted that the present invention does not provide the assisting thrust throughout the entire pitch stroke of the lamp head 2, but only in the area with the greatest load. For example, the pitch range of the lamp head 2 is -30° to +60°. The present invention continuously provides the assisting thrust within the range of the lamp head 2 rotating upward from -30° to -20°, achieving a balance between optimized load sharing and structural safety and reliability.

[0037] The receiving joint 53 includes a fixed column fixedly installed on the support member 3 and a contact sleeve rotatably connected to the fixed column. The contact sleeve contacts the inclined axial surface of the assist head 52 to reduce the friction between the assist head 52 and the receiving joint 53.

[0038] See Figure 2 , Figure 3 and Figure 4 The conversion structure 6 is respectively set between the clamping head 4 and the corresponding translation axis 511 (e.g. Figure 3As shown), it is used to convert the linear motion of the translation axis 511 into the clamping or releasing action of the clamping head 4.

[0039] The gripping head 4 includes two symmetrically arranged and hinged jaws. The conversion structure 6 includes a connecting rod 61, a sliding shaft 62, a gear 63, a threaded sleeve 64, and a rack 65. The gear 63 and the threaded sleeve 64 are coaxially and fixedly connected. The connecting rod 61 is hinged between the jaws and the sliding shaft 62, as shown below. Figure 4 As shown, when the sliding shaft 62 moves backward, the clamping jaws hold and fix the support member 3 via the connecting rod 61. When the sliding shaft 62 moves forward, the clamping jaws release the support member 3 via the connecting rod 61.

[0040] The threaded sleeve 64 is fitted onto the sliding shaft 62 and the two are threadedly engaged. The rack 65 is fixedly connected to the corresponding translation shaft 511 by a connecting bracket 66.

[0041] Taking the translation axis 511 on the right as an example, when the translation axis 511 moves to the right, the connecting frame 66 drives the rack 65 to move to the right, and the meshing gear 63 drives the threaded sleeve 64 to rotate, thereby causing the sliding shaft 62 to move forward. The connecting rod 61 controls the clamping head 4 to release the support member 3. Conversely, when the translation axis 511 moves to the left to reset, the sliding shaft 62 can move backward, controlling the clamping head 4 to clamp and fix the support member 3.

[0042] To prevent the clamping and releasing process of the clamping head 4 from interfering with the assisting process of the assisting head 52, the length of the rack 65 is limited so that the meshing of the rack 65 with the gear 63 only meets the needs of the clamping head 4's opening or clamping action. Figure 4 As shown, as the sliding shaft 62 moves to the right, the rack 65 releases the support member 3 and disengages from the gear 63. At this time, the sliding shaft 62 continues to move to the right, while the clamping head 4 remains stably in the state of releasing the support member 3 due to the self-locking of the threaded sleeve 64 and the sliding shaft 62. The reset process is similar.

[0043] See Figure 3 To further reduce the impact of the external environment on the stability and reliability of the searchlight's operation, a sealed cavity 7 is fixedly installed on the back of the horizontal rotating base 1. Except for the connecting rod 61 and the sliding shaft 62, all other components of the conversion structure 6 are installed within the sealed cavity 7. The sliding shaft 62 is slidably inserted into the sealed cavity 7, while the connecting rod 61 is located outside the sealed cavity 7. By placing relatively precise and environmentally sensitive transmission components such as the gear 63, rack 65, and threaded sleeve 64 within the sealed cavity 7 and sealing and protecting it, the corrosion of these components by high-salt, high-humidity environments and splashing water can be effectively reduced, thereby improving the long-term stability and reliability of the searchlight's operation.

[0044] In the assist structure 5, both the drive component 51 and the elastic component 54 are installed inside the sealed cavity 7, while the assist head 52 and the receiving joint 53 are located outside the sealed cavity 7. The sealed cavity 7 also seals the sliding joint sliding shaft 2 55, which is located between the elastic component 54 and the assist head 52.

[0045] like Figure 4 As shown, the elastic component 54 includes a connector 541, a slider 542, and an elastic component 543. The connector 541 is fixedly connected to the translation shaft 511, the slider 542 is slidably connected to the connector 541, and the elastic component 543 is located between the connector 541 and the slider 542. The end of the slider shaft 55 located inside the sealing cavity 7 is fixedly connected to the slider 542, and the end located outside the sealing cavity 7 is fixedly connected to the assist head 52, thereby realizing the transmission of force between the internal and external components of the sealing cavity 7.

[0046] Specifically: Taking the right translation axis 511 as an example, the connecting piece 541 moves to the right with the translation axis 511. The elastic element 543 causes the sliding piece 542 and the sliding shaft 55 to move to the right, which in turn causes the assist head 52 to move to the right. The assist head 52 stops moving when it comes into contact with the receiving joint 53. As the translation axis 511 continues to move to the right, the elastic element 543 deforms and stores energy. During the upward movement of the right lamp head 2, the stored energy is released, assisting the lamp head 2 in moving upward. The left translation axis 511 works similarly, except that the direction of movement is exactly the opposite.

[0047] Among them, the connecting member 541 and the sliding member 542 are in a limiting sliding connection, such as Figure 4 As shown, by creating a limiting groove on the slider 542 and fixing a limiting block that mates with the limiting groove on the connector 541, the relative sliding stroke between the connector 541 and the slider 542 is limited. This limits the maximum and minimum compression of the elastic element 543, preventing excessive deformation and damage, and also preventing complete relaxation and loss of elasticity during reset. This ensures that the elastic element 543 always operates within a safe and efficient working range, guaranteeing the stability and reliability of the assist structure 5 during long-term operation.

[0048] In embodiments of the present invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," "installed," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, or a sliding connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
