DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: an early warning fence for a ship radar, comprising fences 15 installed at intervals, adjacent fences 15 are connected by a connecting device, and the connecting device comprises a support plate 1, on which three fixing nails 2 connected to the hull are installed. A positioning block 3 is fixedly installed on the top of the support plate 1, and a support column 4 is vertically inserted in the positioning block 3. A bolt 5 is threadedly connected to the positioning block 3, and the bolt 5 passes through the positioning block 3 and is threadedly connected to the support column 4. A guide rod 6 is vertically fixedly installed on the top of the support column 4. Two fixing blocks 9 are fixedly installed at intervals above and below the outer periphery of the guide rod 6, and protrusions 10 are fixedly welded on both sides of the top of the fixing block 9.

[0021] A threaded rod 7 is installed parallel to one side of the guide rod 6, and a turntable 8 is fixedly welded to the bottom of the threaded rod 7. The threaded rod 7 passes through two fixed blocks 9 in sequence and is rotatably mounted with the two fixed blocks 9. A connecting block is fixedly installed on the top of the guide rod 6, and the top of the threaded rod 7 is rotatably mounted with the connecting block. Two sliders 11 are threadedly connected to the outer circumference of the threaded rod 7 at intervals above and below, and both sliders 11 are slidably mounted with the guide rod 6, and both sliders 11 are located above the corresponding fixed blocks 9. Grooves 12 that match the protrusions 10 are provided on both sides of the bottom of the slider 11. Two plug blocks 13 are fixedly welded at intervals on both sides of the fence 15, and the plug blocks 13 are provided with through holes 14 that match the protrusions 10.

[0022] An early warning mechanism is also installed on the fence 15, which includes a voice alarm 20, a warning light 21, a radar millimeter wave sensor 22 and a controller 19. The alarm, the warning light 21, the radar millimeter wave sensor 22 and the controller 19 are all fixedly installed on the top of the fence 15, and the controller 19 is electrically connected to the alarm, the warning light 21 and the radar millimeter wave sensor 22 respectively.

[0023] A support rod 16 is symmetrically fixedly installed on the top of the fence 15, and a solar panel 17 is fixedly installed on the support rod 16. A power supply 18 is also symmetrically fixedly installed on the support rod 16. The power supply 18 and the controller 19 are both located below the solar panel 17, which can protect the power supply 18 and the controller 19 from rain and extend the service life of the power supply 18 and the controller 19. The power supply 18 is electrically connected to the solar panel 17 and the controller 19 respectively. The solar panel 17 converts electrical energy and stores it in the two power supplies 18. The two power supplies 18 provide power for the entire device, so there is no need to connect to an AC power source, which improves the adaptability of the fence 15 to the environment.

[0024] The working principle of the early warning fence of a marine radar provided by the utility model is as follows:

[0025] The support plate 1 is placed at the installation position, and is fixed to the hull by using the fixing nails 2 , and then the bottom of the support column 4 is inserted into the positioning block 3 , and the support column 4 is fixed in the positioning block 3 by the bolts 5 .

[0026] Move the fence 15 to one side of the connection device, move the other fence 15 to the other side of the connection device, and then respectively place the through hole 14 of the plug 13 between the corresponding protrusion 10 and the groove 12, and align the through hole 14 with the protrusion 10, so that the protrusion 10 is inserted into the through hole 14. Then turn the turntable 8, the turntable 8 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the two sliders 11 to move downward at the same time, so that the protrusion 10 enters the corresponding groove 12, and then continue to move the slider 11 downward to contact the plug 13 until it is tightened and stopped, and the two fences 15 are fixed by the connection device. Through the above steps, multiple fences 15 can be installed according to actual conditions.

[0027] The two solar panels 17 can convert solar energy into electrical energy and store it in two power supplies 18. When someone approaches, the radar millimeter wave sensor 22 detects that there is someone in front of the fence 15, and then sends a signal to the controller 19, which controls the voice alarm 20 and the warning light 21 to be powered on, and the voice alarm 20 and the warning light 21 play a warning role.

[0028] When the fence 15 needs to be removed for maintenance or replacement, the turntable 8 is rotated in the opposite direction to disengage the slider 11 from the plug block 13. Thus, the plug block 13 on one side of the fence 15 is released from restriction, and then the turntable 8 on the connecting device on the other side is rotated to release the restriction on the plug block 13 on the other side of the fence 15, and then the fence 15 is removed.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
