Description

Marine searchlight and automatic resetting method thereof

Technical Field

Background

Marine searchlight is an indispensable tool for navigation of a ship at night, and can be used for illumination of the sea surface at night or information exchange with other ships. A marine searchlight generally includes a bracket and a light source, reflector, and one or more optical lenses mounted on the bracket. The light is first gathered into a beam by a reflector (a curved mirror or a spherical mirror), then controlled by the position and combination of the optical lenses, and finally projected.

The common support is a manual adjusting support, and a shipman can adjust the irradiation direction and the irradiation angle of the searchlight through the manual adjusting support. However, since the marine searchlight is generally installed at a higher position of the ship, manual adjustment is difficult and dangerous. Thus, there is a remote control searchlight as disclosed in chinese patent CN107975709a, in which a plurality of motors are provided, and the lamp head can be controlled to rotate in a horizontal direction or a vertical direction by remote control so as to adjust the irradiation direction and angle. However, the remote control searchlight can only rotate and can not automatically reset to the original state, and the searchlight can be irradiated to different positions when being restarted each time, so that the searchlight is inconvenient to use.

Therefore, when the marine searchlight is installed on a ship, the bracket 2 and the lamp cap 1 of the marine searchlight can be controlled by the controller 5 to rotate and adjust in the horizontal and vertical directions so as to conveniently irradiate the area to be irradiated; in order to enable the lamp cap 1 to automatically reset to an initial state after the marine searchlight is used, and facilitate the fixed irradiation of the lamp cap 1 at an automatic centering position when the lamp cap is started next time, the invention provides a method for automatically resetting the marine searchlight.

As shown in fig. 8, the method for automatic reset may include the steps of:

s10: when the reset key 51 is activated, the controller 5 transmits a reset signal to the control unit 4;

S20: the control unit 4 controls the stand 2 to perform the action of rotating and resetting to the horizontal initial position:

S21: when the control unit 4 receives the reset signal, the control unit 4 controls the horizontal motor 32 to rotate forward, and drives the horizontal driven gear 21 and the bracket 2 to rotate towards one direction until the first horizontal limit lug 211 of the horizontal driven gear 21 touches the second horizontal limit lug 33, and the control unit 4 controls the horizontal motor 32 to stop;

S22: the control unit 4 controls the horizontal motor 32 to rotate reversely, so as to drive the horizontal driven gear 21 and the bracket 2 to rotate towards the other direction until the first horizontal limit lug 211 of the horizontal driven gear 21 again touches the second horizontal limit lug 33, and the control unit 4 controls the horizontal motor 32 to stop and records the movement time value of the horizontal reverse direction;

S23: the control unit 4 takes half of the movement time value in the horizontal reverse direction as the horizontal reset time value, the control unit 4 controls the horizontal motor 32 to rotate forward again to drive the horizontal driven gear 21 and the bracket 2 to rotate in the horizontal forward direction, the rotation time length is the horizontal reset time value, and then the horizontal motor 32 stops to enable the bracket 2 to rotate and reset to the horizontal initial position with the lamp cap 1.

S30: the control unit 4 controls the lamp cap 1 to perform the action of rotating and resetting to the vertical initial position:

S31: when the control unit 4 receives a reset signal, the control unit 4 controls the vertical motor 14 to rotate positively and drives the vertical driven gear 12 and the lamp cap 1 to rotate towards one direction, and the control unit 4 controls the vertical motor 14 to stop until one of the limiting parts 15 abuts against the side wall 23 of the bracket 2;

S32: the control unit 4 controls the vertical motor 14 to reversely rotate again, drives the vertical driven gear 12 and the lamp cap 1 to rotate towards the other direction, and controls the vertical motor 14 to stop and records the movement time value of the vertical reverse direction when the other limiting part 15 abuts against the side wall 23 of the other side of the bracket 2;

s33: the control unit 4 takes half of the motion time value in the vertical reverse direction as a vertical reset time value, the control unit 4 controls the vertical motor 14 to rotate forward again to drive the vertical driven gear 12 and the lamp cap 1 to rotate towards the vertical forward direction, the rotation time length is the vertical reset time value, and then the vertical motor 14 stops to enable the lamp cap 1 to rotate and reset to a vertical initial position;

The steps S30 and S20 may be performed simultaneously, or the steps S20 are performed sequentially after the preceding step S30, or the steps S30 are performed sequentially after the preceding step S20.

Therefore, by utilizing the algorithm provided by the invention, when the lamp cap 1 and the bracket 2 are adjusted to any position in the using process, the lamp cap 1 and the bracket 2 can be automatically reset to the initial positions by pressing the reset key 51.

For example, when the lamp cap 1 is lowered by 10 ° and the bracket 2 is turned left by 50 ° and needs to be reset, the reset key 51 is pressed, the control unit 4 drives the horizontal motor 32 to rotate forward, the bracket 2 continues to rotate left (the bracket 2 is set to move left when the horizontal motor 32 rotates forward, or the bracket 2 is set to move right when the horizontal motor 32 rotates forward), the first horizontal limit bump 211 touches the right side surface of the second horizontal limit bump 33, and at this time, the horizontal motor 32 rotates to stop the overload prompt control unit 4 so as to control the horizontal motor 32 to stop running; specifically, when the first horizontal limit bump 211 touches the second horizontal limit bump 33, the horizontal motor 32 is blocked to generate abnormal locked rotation, so that the working current is increased; the control unit 4 detects the working current of the horizontal motor 32, and when the working current exceeds the current preset value of the normal working of the horizontal motor 32, the control unit 4 determines that the first horizontal limit bump 211 touches the second horizontal limit bump 33, so as to control the horizontal motor 32 to stop.

Then the control unit 4 drives the horizontal motor 32 to rotate reversely, after the bracket 2 rotates about 360 degrees to the right, the first horizontal limit lug 211 touches the left side surface of the second horizontal limit lug 33, at this time, the horizontal motor 32 is prevented from rotating, the overload prompt control unit 4 is used for controlling the horizontal motor 32 to stop running, meanwhile, the movement time value in the opposite direction is recorded, the movement time value in the opposite direction is the total time value of one circle of rotation of the bracket 2, the movement time value in the opposite direction is halved to obtain a horizontal reset time value, and the control unit 4 drives the horizontal motor 32 to rotate forward by half of the horizontal reset time value, at this time, the bracket 2 can return to the horizontal initial position; similarly, the lamp cap 1 is controlled by the control unit 4 to drive the vertical motor 14 to rotate forward and backward, and the lamp cap can be reset to the vertical initial position by the two limiting parts 15.

Meanwhile, when the limit part 15 abuts against the side wall 23 of the bracket 2, the rotation of the vertical motor 14 is blocked, and the overload prompt control unit 4 is overloaded at this time, so that the principle of controlling the vertical motor 14 to stop running is the same as that described above. Specifically, when the limiting part 15 abuts against the side wall 23 of the bracket 2, the vertical motor 14 is blocked to generate abnormal locked rotation, so that the working current is increased; the control unit 4 detects the working current of the vertical motor 14, and when the working current exceeds the preset current value of the normal working of the vertical motor 14, the control unit 4 judges that the limiting part 15 abuts against the side wall 23 of the bracket 2, and further controls the vertical motor 14 to stop.

Because the motors with the same or similar parameter types have certain rotating speed and current errors and corresponding locked-rotor currents are different in actual use, the method of the invention adopts the mode of setting the current preset value, detecting whether the working current of the motor is larger than the current preset value, judging whether to control the motor to stop or not and recording the running time of the motor, thereby ensuring the resetting accuracy of the bracket 2 and the lamp cap 1.

Specifically, referring to the following table, by testing a part of motors, the current preset value of the present invention can be set to be 300mA smaller than each rated stall current value, when any motor described below is selected, when the working current continuously rises to 300mA during the operation of the motor, the control unit 4 can determine that the motor is blocked, and stop the motor in advance. Of course, the circuit preset value may be selected in the upper and lower ranges of 300 mA.

In this embodiment, referring to fig. 7, when the bracket 2 is located at the horizontal initial position, a front-rear connection line L1 is provided between the second horizontal limiting bump 33 and the first horizontal limiting bump 211, the base 3 has a central line L2 passing through the horizontal rotation center and extending forward and backward in the middle, and the front-rear connection line L1 and the central line L2 are located on the same vertical plane. Thus, the horizontal initial position of the bracket 2 and the base 1 can be set to a position centered directly in front of the base 3.

Of course, the front-rear connection line L1 may form a certain angle with the center line L2 in a plan view, but as long as the second horizontal limit bump 33 and the first horizontal limit bump 211 are always kept substantially in front-rear distribution, the horizontal initial position of the bracket 2 is not centered but is located in a middle range area toward the front of the base 3.

That is, the horizontal initial position of the bracket can be controlled by adjusting the distribution positions of the second horizontal limit bump 33 and the first horizontal limit bump 211, and the distribution positions can be adjusted when the product comes out.

Specifically, as shown in fig. 4, the base 3 of the present embodiment may include a bottom plate 34 and a bottom cover 35, where the bottom cover 35 and the bottom plate 34 are vertically matched to form a base space S1, and a shaft hole 36 is formed at the top of the bottom cover 35 and is communicated with the base space S1; the control unit 4, the horizontal motor 32, the horizontal driven gear 21 and the horizontal driving gear 31 are arranged in the base space S1; referring to fig. 2, the bottom of the bracket 2 has a spindle 24 passing through the shaft hole 36 and coaxially connected with the horizontal driven gear 21. Thus, the horizontal driven gear 21 rotates horizontally with the main shaft 24 and the bracket 2 as a whole, and the rotational stability can be improved.

And a sealing ring a can be arranged between the bottom cover 35 and the bottom plate 34 for sealing and matching up and down so as to prevent water and dust, and a wire passing hole 37 for communicating the base space S1 with the outside is arranged in the middle of the bottom plate 34, so that cables such as a power supply connecting wire (not shown) can be conveniently connected with all parts in the base space S1.

The bottom of the bracket 2 is provided with a rotating cover 25 at the periphery of the main shaft 24, and the rotating cover 25 is rotatably and hermetically covered on the top surface of the bottom cover 35. The rotating cover 25 can seal the periphery of the shaft hole 36, a sealing ring A can be arranged between the rotating cover and the shaft hole, and the sealing ring A is matched with the sealing between the bottom cover 35 and the bottom plate 34, so that the sealing effect of the base space S1 can be effectively improved, and the service life of the marine searchlight under the marine environment can be prolonged.

In this embodiment, a fixing plate 38 is further disposed in the base space S1, and the fixing plate 38 may be mounted on the lower front side of the horizontal driven gear 21; the horizontal driving gear 31 and the horizontal motor 32 are mounted on the fixed plate 38, and can be respectively positioned above and below the fixed plate 38; the second horizontal limiting bump 33 is disposed on the top surface of the fixing plate 38.

An opening 161 is formed in the bottom of the lamp body 16, and a rotating seat 18 is arranged at the opening 161; the rotary seat 18 can be in sealing engagement with the opening 161 via a sealing ring a.
