[0031] A bracket, used for fixing on a supporting surface;

[0032] A capstan, used for winding a cable, the capstan being rotatably mounted on the bracket, and a rotating shaft hole penetrating the capstan being provided on a side surface of the capstan;

When the unmanned bird-repelling boat accidentally releases or retracts the anchor, and the unmanned bird-repelling boat is unmanned, the anchor cable is locked on the winch by the cable locking mechanism. When the bird-scaring boat starts to move forward, the moving bird-scaring boat will cause entanglement between the anchor and the bracket, thereby causing the pressure of the bracket on the deck to begin to decrease.

[0049] When unmanned bird-scaring boats are performing bird-scaring operations in lakes or swamps around airports, they usually rely on electric anchor machines to moor and fix the boats on the lake surface. However, due to the complex natural conditions of lakes and swamps, there is a problem of incorrect retraction and release when the unmanned bird-scaring boats are retracting and releasing the anchor. That is, the anchor is still fixed to the bottom of the lake, but the system of the unmanned bird-scaring boat has already determined that the anchor has been retracted. If the bird-scaring boat starts to move forward at this time, it is likely to cause the bird-scaring boat to capsize.

[0050] In order to solve the above problems, the present invention proposes an anti-rollover electric anchor winch and an unmanned bird-repelling boat, aiming to provide an electric winch structure that can make timely remedies when the unmanned bird-repelling boat has an anchor that is accidentally retracted or released, wherein: Figures 1 to 3 The figure is a schematic structural diagram of an embodiment of the anti-rollover electric anchor winch provided by the present invention.

[0051] Please refer to Figure 1 The anti-rollover electric anchor winch 1000 includes a bracket 1, a winch 2, a rotating shaft 4, a synchronous rotation mechanism 5, a cable locking mechanism 6, a pressure sensor and a circuit board assembly. The winch 2 is used to wind a cable 3. The winch 2 is rotatably mounted on the bracket 1. The side surface of the winch 2 is provided with a rotating shaft 4 hole 21 that penetrates the winch 2. The rotating shaft 4 is penetrated in the rotating shaft 4 hole 21 to rotatably mount the winch 2 on the bracket 1. The synchronous rotation mechanism 5 is arranged on the rotating shaft 4 to drive the winch 2 to rotate synchronously with the rotating shaft 4. The cable locking mechanism 6 is arranged on the winch 2 to lock the cable 3 on the winch 2. The pressure sensor is arranged at the bottom of the bracket 1 to test the pressure of the bracket 1 on the supporting surface. The circuit board assembly is electrically connected to the pressure sensor.

[0052] In the technical solution of the present invention, the anchor cable 3 is locked on the capstan 2 by the cable locking mechanism 6, and the capstan 2 is connected to the rotating shaft 4 by the synchronous rotating mechanism 5. A pressure sensor is arranged at the bottom of the bracket 1, and the pressure sensor, the synchronous rotating mechanism 5, and the cable locking mechanism 6 are all electrically connected to the circuit board assembly; when the unmanned bird-repelling ship is operating normally, the anchor cable 3 is locked on the capstan 2 by the cable locking mechanism 6, and the capstan 2 can rotate together with the rotating shaft 4 under the drive of the synchronous rotating mechanism 5 to realize the anchoring and retracting of the capstan 2. When the unmanned bird-repelling ship accidentally retracts and releases the anchor, When the unmanned bird-repelling boat starts to move forward, the moving bird-repelling boat will cause entanglement between the anchor and the bracket 1, thereby causing the pressure of the bracket 1 on the deck to begin to decrease. When the pressure decreases to a preset threshold, the pressure sensor will send an electrical signal to the circuit board assembly to enable the circuit board assembly to control the cable locking mechanism 6 to loosen the cable 3, and at the same time control the synchronous rotation mechanism 5 to cancel the synchronous rotation of the winch 2 with the shaft 4. In this way, the cable 3 wound around the winch 2 can drive the winch 2 to rotate under the traction of the anchor until it is completely separated from the winch 2, thereby preventing the unmanned bird-repelling boat from capsizing.

[0053] There are many ways for the cable locking mechanism 6 to lock the cable 3. The cable locking mechanism 6 can pass through the limiting hole provided on the cable 3 through the limiting rod to achieve the purpose of locking the cable 3. The cable locking mechanism 6 can also achieve the purpose of locking the cable 3 through magnetic attraction. Considering that the time from the pressure sensor sensing the change in the pressure of the bracket 1 to the cable locking mechanism 6 releasing the cable 3 is extremely short, therefore, in one embodiment of the present invention, the latter is preferably used as the locking method of the cable 3. Specifically, the outer edge surface of the winch 2 is provided with a mounting groove 22, and the cable locking mechanism 6 includes an electromagnet 61 and a locking block 62. The electromagnet 61 is arranged in the mounting groove 22 and is electrically connected to the circuit board assembly. The center of the electromagnet 61 is recessed downward to form a locking cavity. The upper end of the locking block 62 is used to be fixedly connected to the cable 3, and the lower end of the locking block 62 is arranged in the locking cavity and can be locked in the locking cavity when the electromagnet 61 is energized.

[0054] In the above embodiment, the electromagnet 61 is usually in an energized state to lock the locking block 62 in the locking cavity. When the unmanned bird-repelling ship misjudges the anchor retraction and release, the electromagnet 61 loses power, and the locking block 62 can quickly escape from the locking cavity to complete the rapid separation from the winch 2; and in order to allow the locking block 62 to be locked in the locking cavity by the electromagnet 61, the material of the locking block 62 can be iron or a magnet, and the present invention does not impose any limitation on this.

[0055] Furthermore, in order to facilitate the recovery of the cable 3 after being separated from the winch 2, in one embodiment of the present invention, the locking block 62 is provided with a fixed cavity, and the anti-rollover electric anchor winch 1000 also includes a GPS locator, which is arranged in the fixed cavity. In this way, after the anchor is separated from the winch 2, the anchor salvager can quickly locate the position of the anchor and thus realize the salvage and recovery of the anchor.

[0056] The synchronous rotation mechanism 5 can drive the capstan 2 and the rotating shaft 4 to rotate synchronously by magnetic attraction, or by a limiting rod or a limiting block. The present invention does not limit this. In one embodiment of the present invention, a locking groove 211 is provided inside the hole 21 of the rotating shaft 4, and an installation cavity 41 corresponding to the locking groove 211 is provided on the rotating shaft 4. The synchronous rotation mechanism 5 includes a locking block 51 and a driving assembly 52. ​​The locking block 51 is movably arranged in the installation cavity 41 and has a movement stroke extending into the locking groove 211. The driving assembly 52 is used to drive the locking block 51 to move. When the unmanned bird-repelling boat is in normal operation, the locking block 51 provided on the rotating shaft 4 is locked in the locking groove 211 of the winch 2 under the action of the driving component 52, so as to drive the winch 2 and the rotating shaft 4 to rotate synchronously. When the unmanned bird-repelling boat misjudges the anchoring, the driving component 52 can drive the locking block 51 to disengage from the locking groove 211 under the control of the circuit board component, so as to separate the winch 2 from the rotating shaft 4, so that the winch 2 can rotate under the action of the tension of the cable 3, thereby driving the cable 3 to separate from the winch 2.

[0057] There are many ways to drive the locking block 51 to move. The driving component 52 can be a motor screw or an electric cylinder. The present invention does not limit this. In one embodiment of the present invention, the driving component 52 includes an armature 521, a return spring 522 and an electromagnetic coil 523. The armature 521 is arranged on the side of the locking block 51 away from the locking groove 211, one end of the return spring 522 is connected to the side of the locking block 51 away from the locking groove 211, and the other end is connected to the side of the mounting cavity 41 facing the locking groove 211. The electromagnetic coil 523 is arranged corresponding to the armature 521, and the electromagnetic coil 523 is electrically connected to the circuit board assembly; when no one is driving the bird away. When the ship is in normal operation, the electromagnetic coil 523 loses power, and the locking block 51 is pushed by the reset spring 522 and is locked in the locking groove 211, so that the capstan 2 can rotate with the rotating shaft 4 at any time. At the same time, the reset spring 522 also has a shock-absorbing effect on the locking block 51, preventing the locking block 51 from having hard contact with the locking groove 211 when the capstan 2 rotates, thereby increasing the service life of the locking block 51; when the unmanned bird-repelling ship misjudges the anchoring, the electromagnetic coil 523 is energized and absorbs the locking block 51 through the armature 521 to move downward, so as to achieve the separation between the rotating shaft 4 and the capstan 2.

[0058] There are many ways to drive the anti-rollover electric anchor winch 1000. The anti-rollover electric anchor winch 1000 can be driven by a rotating cylinder or by a rotating motor 7. The present invention prefers the latter. Specifically, in one embodiment of the present invention, the anti-rollover electric anchor winch 1000 also includes a rotating motor 7. The rotating motor 7 has a rotating shaft. The rotating motor 7 is fixed on the bracket 1. The rotating shaft passes through the bracket 1 and is fixedly connected to the rotating shaft 4. In this way, the rotating shaft 4 is driven to rotate, thereby driving the winch 2 to rotate.

[0059] It can be understood that when the unmanned bird-repelling boat is anchored, the waves in the lake may also cause the anchor to pull the bracket 1. If the waves are too large, causing the pressure of the bracket 1 on the deck to be reduced to a preset threshold, it may also cause the anti-rollover electric anchor winch 1000 to be falsely started. To solve the above problem, in one embodiment of the present invention, a frequency sensing component is provided at the bottom of the bracket 1 to detect the vibration of the hull of the unmanned bird-repelling boat. Specifically, a frequency sensing component is also provided at the bottom of the bracket 1 to detect the vibration frequency of the bird-repelling boat. The frequency sensing component is electrically connected to the circuit board component. When the unmanned bird-repelling boat is in a moored state, the engine of the unmanned bird-repelling boat is turned off and the hull amplitude is reduced. When the unmanned bird-repelling boat is in a moving state, the engine of the unmanned bird-repelling boat is turned on and the hull amplitude is increased. In this way, by monitoring the amplitude of the hull of the unmanned bird-repelling boat, the operation of the unmanned bird-repelling boat is monitored to avoid the unmanned bird-repelling boat being pulled by the waves when it is moored, thereby preventing the anti-rollover electric anchor winch 1000 from falsely starting.

[0060] The frequency sensing component may be a varistor or a piezoelectric ceramic. From the perspective of detection sensitivity, in one embodiment of the present invention, the frequency sensing component includes a piezoelectric ceramic arranged along the width direction of the bracket 1.

[0061] In order to prevent the cable 3 from deviating to both sides when winding, in one embodiment of the present invention, the anti-rollover electric anchor winch 1000 also includes a limit plate 23, and the limit plate 23 is arranged on both sides of the winch 2, so as to provide a limit for the cable 3 to prevent the cable 3 from deviating.

[0062] The present invention also proposes an unmanned bird-repelling boat, which includes an anti-rollover electric anchor winch. The specific structure of the anti-rollover electric anchor winch refers to the above-mentioned embodiment. Since the unmanned bird-repelling boat adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
