A zonal detection system for a port access according to a preferred embodiment of the present invention, including a defense detection assembly 10, a first winch 20, a second winch 30, and a detection unit 40, will be disclosed and described in the following description with reference to fig. 1 to 5 of the drawings accompanying the description of the present invention.
Specifically, the defending and detecting assembly 10 includes a defending net assembly 11, the defending net assembly 11 further includes at least two detecting nets 111 and at least two floats 112, the detecting nets 111 are sequentially connected, at least one float 112 is disposed on top of each detecting net 111, so that the floats 112 provide buoyancy for suspending the detecting nets 111 in the water area of the access way of the port. The first winch 20 and the second winch 30 are respectively arranged at opposite sides of an access port of the port, one end of the defending net assembly 11 is operatively connected to the first winch 20, the other end is operatively connected to the second winch 30, the first winch 20 and the second winch 30 are cooperatively capable of expanding or collapsing the defending net assembly 11, wherein when the first winch 20 and the second winch 30 are cooperatively expanding the defending net assembly 11, the access port of the port is closed to prevent a ship or the like from entering the port through the access port, and correspondingly, when the first winch 20 and the second winch 30 are cooperatively collapsing the defending net assembly 11, the access port of the port is opened to allow the ship or the like to enter the port through the access port, so the defending net assembly 11 provides a defending function.
That is, when the first winch 20 and the second winch 30 are cooperated to unwind the defending net assembly 11, the buoys 112 of the defending net assembly 11 provide buoyancy for suspending the detecting nets 111 in the water of the port in order to provide physical defending function by the detecting nets 111, i.e., the detecting nets 111 are used to intercept an intruded object for preventing the intruded object from entering and exiting the port through the port of the port.
It should be noted that, when the first winch 20 and the second winch 30 cooperate to extend the defending net assembly 11, the buoys 112 of the defending net assembly 11 provide buoyancy for suspending the detecting nets 111 in the water of the port access passage to close the port access passage and prevent the ship from entering the port through the access passage. When the first winch 20 and the second winch 30 are cooperated to retract the defending net assembly 11, the buoys 112 of the defending net assembly 11 provide buoyancy for suspending the detecting nets 111 in the water area on the shore of the port to open the access way of the port for allowing the ship and the like to access the port through the access way.
In one specific example of the zonal detection system of the present invention, referring to fig. 1 and 2, the defending detection assembly 10 comprises a main cable 13 and at least two connecting cables 14, wherein the main cable 13 is disposed across the access way of the port, and one end of the main cable 13 is operatively connected to the first winch 20, the other end is operatively connected to the second winch 30, one of the detection nets 111 proximate to the second winch 30 is fixedly connected to the main cable 13, the other detection net 111 is movably connected to the main cable 13, adjacent ones of the floats 112 are respectively connected by at least one of the connecting cables 14, and one of the floats 112 proximate to the first winch 20 is disposed in a horizontal position relative to the first winch 20, such that one end operatively connected to the defending net assembly 11 is operatively connected to the first winch 20 and the other end operatively connected to the second winch assembly 30. In other words, opposite ends of the defending net assembly 11 are operatively connected to the first winch 20 and the second winch 30 by the main rope 13 and the connecting cable 14.
Specifically, when the first winch 20 unwinds the main rope 13 and the second winch 30 unwinds the main rope 13, the main rope 13 pulls the detecting net 111 fixedly connected to the main rope 13 to move toward the second winch 30, the float 112 provided to this detecting net 111 pulls the remaining detecting net 111 to move toward the second winch 30 through the connecting rope 14, so that the first winch 20 and the second winch 30 cooperate to unwind the defending net assembly 11, and these float 112 provide buoyancy for suspending these detecting nets 111 in a water area of a port access passage to close the port access passage for preventing a ship or the like from entering and exiting the port through the access passage. When the first winch 20 is used for reeling the main rope 13 and the second winch 30 is used for reeling the main rope 13, the main rope 13 pulls the detecting net 111 fixedly connected to the main rope 13 to move towards the direction approaching the first winch 20, the detecting net 111 arranged at the corresponding position is pulled to move towards the direction approaching the first winch 20 after the detecting net 111 contacts the detecting net 112 adjacent to the detecting net 111, so that the first winch 20 and the second winch 30 cooperate to fold the defending net assembly 11, and the detecting net 111 is suspended in a water area on the side of the port by the buoyancy provided by the detecting net 112 to open an access passage of the port for allowing a ship or the like to pass through the access passage of the port.
It should be noted that, since the detection nets 111 of the defending net assembly 11 are connected to the main rope 13 (i.e., one of the detection nets 111 near the second winch 30 is fixedly connected to the main rope 13, and the other detection net 111 is movably connected to the main rope 13), the main rope 13 can limit the positions of the detection nets 111 after the defending net assembly 11 is unfolded to close the access passage of the port, thereby preventing the detection net 111 from being greatly displaced due to the swing of waves of the buoy 112 provided to the detection net 111, and thus ensuring that the defending net assembly 11 is suspended in the water area of the access passage of the port to provide a function.
In one example of the partition detection system of the present invention, referring to fig. 1 and 2, the partition detection system further includes two elevation assemblies 50, each of the elevation assemblies 50 includes a vertical column 51, an elevation float 52, a locking mechanism 53, and a pulley 54, respectively, the vertical column 51 has a limit space 511, the elevation float 52 is movably disposed in the limit space 511 of the vertical column 51, the locking mechanism 53 is disposed in the elevation float 52, and the locking mechanism 53 is disposed to lock or release the vertical column 51, and the pulley 54 is disposed in the locking mechanism 53. One of the height-adjusting members 50 is disposed inside the first winch 20, and the extending direction of the upright 51 of this height-adjusting member 50 coincides with the height direction of the probe net 111, one end portion of the main rope 13 is operatively connected to the first winch 20 after passing around the pulley 54 of this height-adjusting member 50, the other height-adjusting member 50 is disposed inside the second winch 30, and the extending direction of the upright 51 of this height-adjusting member 50 coincides with the height direction of the probe net 111, and the other end portion of the main rope 13 is operatively connected to the second winch 30 after passing around the pulley 54 of this height-adjusting member 50. In other words, the upright 51 of one of the height adjustment assemblies 50 is disposed inside the first winch 20 in a standing posture, and the upright 51 of the other of the height adjustment assemblies 50 is disposed inside the second winch 30 in a standing posture.
When the locking mechanism 53 releases the upright 51, the height positions of the lifting block 52, the locking mechanism 53 and the pulley 54 can be changed with the change of the height of the water surface based on the buoyancy provided by the lifting block 52, and the upright 51 can limit the moving directions of the lifting block 52, the locking mechanism 53 and the pulley 54, accordingly, the height positions of the lifting block 52, the locking mechanism 53 and the pulley 54 are kept unchanged when the locking mechanism 53 locks the upright 51, thus facilitating not only the paying-off and paying-in operations of the main rope 13 by the first winch 20 and the second winch 30 to pay-out or pay-in the defending net assembly 11, but also the avoidance of the additional load caused by the dead weight of the defending net assembly 11 to the first winch 20 and the second winch 30 and the avoidance of the additional load caused by the pulling force provided by the floating part 112 to the first winch 20 and the second winch 30.
Specifically, when the water surface rises, the locking mechanism 53 is allowed to release the upright 51, and the height positions of the lifting float 52, the locking mechanism 53, and the pulley 54 are automatically adapted to the height position of the water surface based on the buoyancy provided by the lifting float 52, so that the floating portion 112 is prevented from providing a pulling force due to the lifting and acting on the first winch 20 and the second winch 30, and thus the first winch 20 and the second winch 30 do not bear an additional load due to the pulling force provided by the floating portion 112. When the water surface is lowered, the locking mechanism 53 is allowed to release the upright post 51, and the height positions of the lifting float 52, the locking mechanism 53 and the pulley 54 are automatically adapted to the height position of the water surface based on the buoyancy provided by the lifting float 52, so that the height of the two end portions of the defending net assembly 11 cannot be lowered with the lowering of the water surface to provide a pulling force and act on the first winch 20 and the second winch 30, and thus the first winch 20 and the second winch 30 cannot bear an additional load due to the pulling force provided by the self weight of the defending net assembly 11. After the height position of the defending net assembly 11 is adjusted to the height position suitable for the water surface, the locking mechanism 53 locks the upright post 51, so that the height position of the pulley 54 of the height adjusting assembly 50 is kept unchanged during the process of expanding the defending net assembly 11 or the process of folding the defending net assembly 11, and the first winch 20 and the second winch 30 are beneficial to the cable laying and folding operation of the main cable 13.
In one example of the zonal detection system of the present invention, with continued reference to fig. 1 and 2, the zonal detection system further comprises two limiting assemblies 60, each limiting assembly 60 comprises at least one limiting post 61 and a limiting mechanism 62 movably disposed up and down on the limiting post 61, one limiting assembly 60 is disposed inside the height adjusting assembly 50 adjacent to the first winch 20, and the extending direction of the limiting post 61 of this limiting assembly 60 coincides with the extending direction of the upright 51 of this height adjusting assembly 50, one end of the main rope 13 is movably connected to the limiting mechanism 62 of this limiting assembly 60, this limiting assembly 60 is used to limit the end of the first winch 20 from being swung laterally, which is adjacent to the first winch 20, to avoid causing additional load to the first winch 20 and to avoid this end of the main rope 13 from falling off the pulley 54. The other limit assembly 60 is disposed inside the raising assembly 50 adjacent to the second winch 30, and the extending direction of the limit post 61 of this limit assembly 60 is identical to the extending direction of the upright 51 of this raising assembly 50, the other end of the main rope 13 is movably connected to the limit mechanism 62 of this limit assembly 60, this limit assembly 60 serves to limit the lateral swing of the end of the defending net assembly 11 adjacent to the second winch 30, to avoid causing additional load to the second winch 30 and to avoid dropping of this end of the main rope 13 from the pulley 54.
In a specific example of the partition detection system of the present invention, the limit assembly 60 includes two limit posts 61, the main rope 13 passes through a gap formed between the two limit posts 61, wherein opposite ends of the limit mechanism 62 are respectively provided with a limit groove 621, wherein the limit posts 61 are positioned in the limit grooves 621 of the limit mechanism 62 such that the limit mechanism 62 surrounds the limit posts 61, and thus, the limit mechanism 62 is movably disposed at the limit posts 61 up and down, and the two limit posts 61 cooperate with each other to prevent the limit mechanism 62 from rotating.
In a specific example of the zonal detection system of the present invention, one of the floats 112, which is adjacent to the first winch 20, is connected to the spacing mechanism 62 of the spacing assembly 60 adjacent to the first winch 20 by at least one of the connecting cables 14, and since the horizontal positions of the spacing mechanism 62 and the first winch 20 remain unchanged, the horizontal position of one of the floats 112, which is adjacent to the first winch 20, is set to remain unchanged with respect to the horizontal position of the first winch 20.
In this particular example of the zoned detection system of the present invention shown in fig. 1 to 5, each of the detection nets 111 of the defending net assembly 11 is woven from one complete optical fiber, and the detection nets 111 are connected to the detection unit 40 such that the defending net assembly 11 has not only a physical interception function but also a detection function. In another specific example of the zoned detection system of the present invention, a rope integrated with a plurality of sensors may be used to weave the detection net 111 of the defending net assembly 11.
Specifically, in some embodiments of the zonal detection system of the present invention, the detection nets 111 of the defending net assembly 11 are connected to the detection unit 40 after being connected in series, after the defending net assembly 11 is unfolded and the buoyancy provided by the buoys 112 suspends the detection nets 111 in the water area of the port access passage, the detection unit 40 can make light waves propagate in the detection nets 111, when an invading object impacts or breaks the detection nets 111, the detection nets 111 reflect light waves due to vibration, reflected light waves can be received by the detection unit 40, and the detection unit 40 can determine the specific position of the defending net assembly 11 impacted or broken by the invading object according to the reflected light waves, thereby determining the position of the invading object in the port access passage.
In other embodiments of the zoned detection system of the present invention, the detection nets 111 of the defending net assembly 11 are divided into at least two groups connected in parallel, each detection net 111 of each group of detection nets 111 is connected in series, and each group of detection nets 111 is individually connected to the detection unit 40, after the defending net assembly 11 is unfolded and the buoyancy provided by the buoys 112 suspends the detection nets 111 in the water area of the port access duct, the detection unit 40 can make light waves propagate in each detection net 111 of each group of detection nets 111, when an invasive object impacts or breaks the detection nets 111, the detection nets 111 vibrate to reflect light waves, the reflected light waves can be received by the detection unit 40, and the detection unit 40 can determine the specific position of the defending net assembly 11 impacted or broken by the invasive object according to the reflected light waves, thereby determining the position of the invasive object in the port access duct. It is worth mentioning that by grouping these detection networks 111 and connecting them to the detection units 40 in groups, light waves can be prevented from propagating in ultra-long optical fibers.
In one example of the zonal detection system of the present invention, referring to fig. 1 to 5, the defending detection assembly 10 further includes an anti-climb detection cable 15, the anti-climb detection cable 15 is disposed on top of the defending net assembly 11, and the anti-climb detection cable 15 is connected to the detection unit 40. After the defending net assembly 11 is deployed and the buoyancy provided by the buoys 112 suspends the detecting net 111 in the body of water of the port access way, the anti-climb detecting cable 15 spans the port access way. In this specific example of the present invention, the anti-climbing detection cable 15 may be an optical fiber cable, the detection unit 40 may enable light waves to propagate in the anti-climbing detection cable 15, when an intruded object hits, breaks or climbs the anti-climbing detection cable 15, the anti-climbing detection cable 15 reflects light waves due to vibration, the reflected light waves may be received by the detection unit 40, and the detection unit 40 may determine a specific position of the anti-climbing detection cable 15 hit, broken or climbed by the intruded object according to the reflected light waves, thereby determining a position of an access passage of the intruded object at the port. By providing the anti-climb detection cable 15 on top of the defending net assembly 11 across the port access way, the zoned detection system of the present invention is able to prevent intrusion of intrusion objects into the port from the space above the water surface.
In one specific example of the zoned detection system of the present invention, referring to fig. 2 and 3, the anti-climb detection cables 15 are connected above the detection nets 111 to set the anti-climb detection cables 15 on top of the defending net assembly 11, and the state of the anti-climb detection cables 15 can be changed as the state of the defending net assembly 11 is changed. Specifically, when the first winch 20 and the second winch 30 cooperate with each other to unwind the defending net assembly 11, the anti-climb detection cable 15 spans the access way of the port, and when the first winch 20 and the second winch 30 cooperate with each other to retract the defending net assembly 11, the anti-climb detection cable 15 moves away from the access way of the port.
It is worth mentioning that the specific way of connecting the anti-climb detection cable 15 and the top of the detection net 111 is not limited in the zoned detection system of the invention. For example, in this particular example of the zoned detection system shown in fig. 1-5, a tie 70 may be used to fixedly connect the anti-climb detection cable 15 over the detection net 111, ensuring that the anti-climb detection cable 15 is located on top of the defending net assembly 11.
In one example of the zonal detection system of the present invention, referring to fig. 1 to 5, the defending detection assembly 10 further includes a bottom-out prevention detection cable 16, the bottom-out prevention detection cable 16 is disposed at the bottom of the defending net assembly 11, and the bottom-out prevention detection cable 16 is connected to the detection unit 40. After the defending net assembly 11 is deployed and the buoyancy provided by the buoys 112 suspends the detecting nets 111 in the body of water of the port access way, the anti-drilling detecting cable 16 spans the port access way. The detection unit 40 can make light waves propagate in the anti-drilling detection cable 16, in this specific example of the present invention, the anti-drilling detection cable 16 may be an optical fiber cable, when an invaded object hits, breaks or lifts the anti-drilling detection cable 16, the anti-drilling detection cable 16 reflects light waves due to vibration, the reflected light waves can be received by the detection unit 40, and the detection unit 40 can determine a specific position where the anti-drilling detection cable 16 is hit, broken or lifted by the invaded object according to the reflected light waves, so as to determine a position where the invaded object is located in an access way of a port. By providing the anti-drilling detection cable 16 at the bottom of the defending net assembly 11 across the access way of the port, the zoning detection system of the present invention can prevent intrusion of an intrusion object into the port from the space below the defending net assembly 11.
In one specific example of the zonal detection system of the present invention, referring to fig. 2 and 3, the anti-drilling detection cables 16 are connected below the detection nets 111 to place the anti-drilling detection cables 16 on top of the defending net assembly 11, and the state of the anti-drilling detection cables 16 can be changed with the change of the state of the defending net assembly 11. Specifically, when the first winch 20 and the second winch 30 cooperate with each other to unwind the defending net assembly 11, the anti-drilling detection cable 16 crosses the access way of the port, and when the first winch 20 and the second winch 30 cooperate with each other to retract the defending net assembly 11, the anti-drilling detection cable 16 moves away from the access way of the port.
It should be noted that the specific manner of connecting the bottom-drilling-resistant detection cable 16 and the top of the detection network 111 is not limited in the zoned detection system of the present invention. For example, in this particular example of the zoned detection system shown in fig. 1-5, the tie 70 may be used to fixedly connect the anti-drilling detection cable 16 to the underside of the detection net 111, ensuring that the anti-drilling detection cable 16 is located at the bottom of the defending net assembly 11.
That is, in this specific example of the zonal detection system of the present invention shown in fig. 1 to 5, the defending net assembly 11 is provided with one anti-climb detection cable 15 at the top, one anti-drill detection cable 16 at the bottom, and after the defending net assembly 11 is deployed and the buoyancy provided by the buoys 112 suspends the detection nets 111 in the water area of the access port, the anti-climb detection cable 15 is held by the defending net assembly 11 at the top of the defending net assembly 11 and spans the access port, the anti-drill detection cable 16 is held by the defending net assembly 11 at the bottom of the defending net assembly 11 and spans the access port, the anti-drill detection cable 16 is invaded by an invaded object to cause the anti-climb detection cable 15, the anti-drill detection cable 16 or the detection net 111 to vibrate, the detection unit 40 is capable of receiving the anti-climb detection cable 15, the anti-drill detection cable 16 or the detection net 111 to thereby make a reflection on the light wave, and the anti-climb detection cable 16 is capable of determining the position of the invaded object at the port by the specific access port by the anti-drill detection cable 11 and the optical wave detection cable at the access port, the high position of the access port. For example, when an intruder hits or breaks the detection net 111 of the defending net assembly 11 from the middle part of the water area of the access way of the port, the detection net 111 vibrates and causes light wave reflection, the detection unit 40 receives the reflected light wave in the detection net 111 and can determine the position of the intruder at the middle part of the water area of the access way of the port according to the reflected light wave, when the intruder hits, breaks or climbs the anti-climbing detection cable 15, the anti-climbing detection cable 15 vibrates and causes light wave reflection, the detection unit 40 receives the reflected light wave in the anti-climbing detection cable 15 and can hit, break or climb the anti-climbing detection cable 15 according to the reflected light wave, when the intruder hits, breaks or lifts the anti-boring detection cable 16, the anti-boring detection cable 16 vibrates and causes light wave reflection, and the detection unit 40 receives the reflected light wave in the anti-boring detection cable 16 according to the reflection at the position where the anti-boring detection cable 16 is hit, broken or lifted by the reflected light wave, so that the access way of the port can be partitioned.
In addition, the anti-climb detection cables 15 are segmented, the detection networks 111 are grouped, and the positions of each segment of the anti-climb detection cables 15 and the positions of each group of detection networks 111 are in one-to-one correspondence, so that the false alarm rate of the partitioned detection system is reduced. Fig. 2 and 3 show a specific example of the sectionalized detection system according to the present invention for sectionalizing the anti-climb detection cable 15, where the anti-climb detection cable 15 is provided with a margin 100 at a connection position of two adjacent detection nets 111, and the margin 100 is used for sectionalizing the anti-climb detection cable 15, preventing or reducing vibration from propagating from one section to another section of the anti-climb detection cable 15, so as to accurately locate a position where an intruded object hits the anti-climb detection cable 15, and reduce a false alarm rate. Specifically, when the access passage of the port is invaded by an invaded object to cause the vibration of the portion of the anti-climbing detection cable 15 corresponding to one of the detection nets 111, the balance 100 prevents the vibration of the portion of the anti-climbing detection cable 15 from propagating to the portion of the anti-climbing detection cable 15 corresponding to the adjacent detection net 111, thereby reducing the false alarm rate.
Accordingly, the anti-drilling detection cables 16 are segmented, and the position of each segment of the anti-drilling detection cable 16 corresponds to the position of each group of the detection network 111 one by one, so that the false alarm rate of the zoned detection system is reduced. The same manner as the segmentation of the anti-climbing detection cable 15, the anti-drilling detection cable 16 is provided with a disc margin 100 at the connection position of two adjacent detection nets 111, and the disc margin 100 is used for segmenting the anti-drilling detection cable 16, preventing or reducing vibration from propagating from one segment to the other segment of the anti-drilling detection cable 16, so as to accurately position the position where an invasive object collides with the anti-drilling detection cable 16, and reduce the false alarm rate. Specifically, when the access port is invaded by an invaded object to cause the vibration of the portion of the anti-drilling detection cable 16 corresponding to one of the detection networks 111, the balance 100 prevents the vibration of the portion of the anti-drilling detection cable 16 from propagating to the portion of the anti-drilling detection cable 16 corresponding to the adjacent detection network 111, thereby reducing the false alarm rate.
In this particular example of the zoned detection system shown in fig. 1-5, the detection web 111 comprises a plurality of laterally extending portions 1111, a plurality of longitudinally extending portions 1112 and a plurality of catches 1113, the laterally extending portions 1111 being connected end to end, the longitudinally extending portions 1112 being located above the laterally extending portions 1111, one of the longitudinally extending portions 1112 being connected to one of the laterally extending portions 1111, the intersection of the laterally extending portions 1111 and the longitudinally extending portions 1112 being locked by one of the catches 1113. The lateral extensions 1111 and the longitudinal extensions 1112 of the detection net 111 are woven from one complete optical fiber.
Referring to fig. 2 to 5, the float portion 112 of the defending net assembly 11 includes a mounting frame 1121 and two floats 1122, the mounting frame 1121 further includes a frame body 11211 and two extending arms 11212, the frame body 11211 includes a curved connecting portion 112111 and two leg portions 112112, two of the leg portions 112112 integrally extend downward from both ends of the connecting portion 112111, respectively, so that the frame body 11211 is in a "U" shape, two of the extending arms 11212 extend inward from two of the leg portions 112112 of the frame body 11211, respectively, and one of the floats 1122 is mounted to the two leg portions 112112 of the frame body 11211, respectively. The top of the detecting net 111 is mounted to the connection portion 112111 of the frame body 11211, the middle of the detecting net 111 is mounted to the two extension arms 11212, the float part 112 is disposed above the detecting net 111, and the opposite sides of the detecting net 111 are respectively maintained with one float 1122, so that the two floats 1122 of the float part 112 can provide balanced buoyancy at the opposite sides of the detecting net 111 to avoid tilting of the top of the defending net assembly 11.
It should be noted that the specific manner in which the top of the detection net 111 is mounted to the frame 11211 is not limited in the zoned detection system of the present invention. For example, in this particular example of the zoned detection system of the present invention shown in fig. 1-5, the float 112 includes a top mounting mechanism 1123, the top mounting mechanism 1123 including a top first clamp plate 11231 and a top second clamp plate 11232, the top first clamp plate 11231 being disposed on the connecting portion 112111 of the frame 11211, for example, the top first clamp plate 11231 may be welded to the connecting portion 112111 of the frame 11211, the top second clamp plate 11232 being mounted to the top first clamp plate 11231 to clamp the top of the detection net 111 between the top first clamp plate 11231 and the top second clamp plate 11232, such that the top of the detection net 111 is mounted to the connecting portion 112111 of the frame 11211.
It is also worth mentioning that the specific way in which the middle of the detection net 111 is mounted to the two extension arms 11212 is not limited in the zoned detection system of the present invention. For example, in this particular example of the zonal detection system of the present invention shown in fig. 1-5, the float portion 112 includes a middle mounting mechanism 1124, the middle mounting mechanism 1124 includes a middle first clamp plate 11241 and a middle second clamp plate 11242, the middle first clamp plate 11241 and the middle second clamp plate 11242 clamp the middle of the detection net 111, and the middle first clamp plate 11241 and the middle second clamp plate 11242 are locked between the two extension arms 11212, such that the middle of the detection net 111 is mounted to the two extension arms 11212.
Referring to fig. 2 to 5, the float part 112 further includes two sets of float weights 1125, and a set of float weights 1125 is disposed below each float 1122, wherein the float weights 1125 are used to stand the float 1122 in a water area.
With continued reference to fig. 2 and fig. 4, the defending net assembly 11 further includes at least one net balancing weight 113, the net balancing weight 113 is disposed at the bottom of the detecting net 111, wherein after the defending net assembly 11 is unfolded and the detecting net 111 is suspended in a water area of the port access passage by the float portion 112, gravity provided by the net balancing weight 113 keeps the detecting net 111 in a flat state, so as to avoid the problem that the detecting net 111 curls in a height direction to generate defending loopholes.
With continued reference to fig. 4 and 5, the defending net assembly 11 further includes at least two lifting portions 114, the lifting portions 114 including a lifting motor 1141, a spool 1142, and a lifting cable 1143, the lifting motor 1141 being mounted to one of the two extension arms 11212 of the mounting frame 1121, the spool 1142 being mounted to an output shaft of the lifting motor 1141, the lifting cable 1143 being wound around the spool 1142, and an end of the lifting cable 1143 being connected to a middle portion of the detecting net 111. When the output shaft of the lifting motor 1141 rotates, the output shaft of the lifting motor 1141 drives the drum 1142 to synchronously rotate, so as to realize the retraction or unwinding operation of the lifting cable 1143, wherein when the lifting motor 1141 drives the drum 1142 to rotate to retract the lifting cable 1143, the lifting portion 114 lifts the middle and bottom of the detection net 111 upwards, so that the detection net 111 and the anti-drilling detection cable 16 are separated from the ground, for example, the lifting portion 114 can make the detection net 111 and the anti-drilling detection cable 16 separate from the sea floor, the river floor or the lake floor, so that when the first winch 20 and the second winch 30 mutually cooperate to retract the defending net assembly 114, the situation that the detection net 111 and the anti-drilling detection cable 16 drag the ground is avoided, and accordingly, when the first winch 20 and the second winch 30 mutually cooperate to unwind the detection net 111, the anti-drilling detection cable 16, the lifting cable 11 is correspondingly deployed, and the anti-drilling protection cable 16 can simultaneously move in and out of the port channel 1143, and the anti-drilling protection cable 16 can make the anti-drilling protection net assembly 11 move in and out of the port channel 1141, and the port channel 11 can simultaneously, and the anti-drilling protection cable assembly is driven in and out of the port channel 114is realized.
Referring to fig. 1 to 5, the defending net assembly 11 further includes at least one alarm portion 115, and the alarm portion 115 is disposed on the top of the frame body 11211 of the assembly frame 1121 for providing an alarm. Preferably, the alarm portion 115 is an audible and visual alarm portion, which alarms by providing sound and optical fibers. Since the anti-climb detection cables 15 and the anti-drill bottom detection cables 16 are segmented and the detection nets 111 are grouped while the alarm portions 115 are provided at the buoys 112 at the tops of the detection nets 111, each segment of the anti-climb detection cables 15, each segment of the anti-drill bottom detection cables 16, each group of the detection nets 111 are respectively provided with at least one alarm portion 115, and when an intruded object hits the anti-climb detection cables 15, the anti-drill bottom detection cables 16 or the detection nets 111 at a specific position in the width direction of the access port, the alarm portion 115 at the corresponding position provides an alarm to indicate the position in the width direction of the port where the access port is intruded. Meanwhile, according to the light waves reflected by the anti-climbing detection cable 15, the anti-drilling detection cable 16 or the detection network 111, the position of the port in and out channel in the height direction of the port can be determined, so that the intrusion position of the port in and out channel can be accurately judged.
Fig. 6 and 7 show a modified example of the detection net 111 of the partitioned detection system according to the above preferred embodiment of the present invention, unlike the detection net 111 of the partitioned detection system shown in fig. 1 to 5, in this specific example of the partitioned detection system shown in fig. 6 and 7, the detection net 111 includes a plurality of wavy lateral extensions 1111, and the peak position of one of the lateral extensions 1111 and the valley position of the adjacent lateral extension 1111 are fixedly connected, so that the detection net 111 can provide a good buffer space, reduce the instantaneous impact force of an intrusion object on the detection net 111, and improve the stability and reliability of the partitioned detection system.
Specifically, when the invasive object impacts the detection net 111, the width direction of the detection net 111 may extend, and the height direction may shrink, so that the detection net 111 has a good buffer space, the instant impact force of the invasive object on the detection net 111 is reduced, and after the impact of the invasive object is finished, the gravity provided by the net body balancing weight 113 enables the detection net 111 to recover to an initial state.
Preferably, the locking catch 1113 is configured to lock the peak position of one lateral extension 1111 and the valley position of an adjacent lateral extension 1111, such that the peak position of one lateral extension 1111 and the valley position of an adjacent lateral extension 1111 are fixedly connected.
With continued reference to fig. 6 and 7, the probe web 111 includes a longitudinally extending portion 1112, one end of the longitudinally extending portion 1112 being connected to one end of a bottommost one of the transversely extending portions 1111, the other end of the longitudinally extending portion 1112 extending to the top of the probe web 111, thus facilitating connection of opposite ends of a complete optical fiber used to weave the probe web 111 to the probe unit 40.
In addition, it can be understood that since the probe net 111 includes a plurality of wavy lateral extensions 1111, and the peak position of one lateral extension 1111 and the valley position of the adjacent lateral extension 1111 are fixedly connected, the probe net 111 is formed with a plurality of columns of the mesh holes 1114, and the columns of the mesh holes 1114 are distributed along the width direction of the probe net 111. The longitudinally extending portions 1112 of the probe web 111 are held at the outermost side of the probe web 111 in such a manner as to pass sequentially through each of the cells 1114 of the outermost column of the cells 1114.
Preferably, said longitudinal extension 1112 of said detection net 111 is arranged for connecting two adjacent said detection nets 111. Specifically, firstly, the side of one of the probe nets 111 provided with the longitudinal extension 1112 and the side of the other probe net 111 not provided with the longitudinal extension 1112 are overlapped, and secondly, the longitudinal extension 1112 of one of the probe nets 111 is allowed to pass through each of the mesh holes 1114 in the outermost one of the two probe nets 111 in turn in a "needle-threading" manner, so that the longitudinal extension 1112 of one of the probe nets 111 can connect the two probe nets 111 together.
It will be appreciated that the shorter length of optical fibers used to weave the detection net 111 shown in fig. 6 and 7, as compared to the detection net 111 of the zoned detection system shown in fig. 1-5, not only facilitates reducing the cost of the detection net 111, but also the space that the defensive detection assembly 10 takes up in the collapsed state, facilitates reducing the cost and difficulty of deploying the zoned detection system at a port.
Fig. 8 shows a modified example of the detection net 111 of the partitioned detection system according to the above preferred embodiment of the present invention, unlike the detection net 111 of the partitioned detection system shown in fig. 1 to 5, in this specific example of the partitioned detection system shown in fig. 8, the anti-climb detection cables 15 extend in a wavy shape, the connection positions of adjacent two of the detection nets 111 correspond to the peak position or the trough position of the anti-climb detection cables 15, and the connection positions of adjacent two of the detection nets 111 and the peak position or the trough position of the anti-climb detection cables 15 are not fixedly connected in such a manner that, when an intrusion of an access port by an intrusion object causes a vibration of a portion of the anti-climb detection cables 15 corresponding to one of the detection nets 111, the peak position or the trough position of the anti-climb detection cables 15 prevents a vibration of the portion of the anti-climb detection cables 15 from being transmitted to the portion of the anti-climb detection cables 15 corresponding to the adjacent one of the detection nets 111, thereby reducing a false alarm rate.
Accordingly, the anti-drilling detection cable 16 extends in a wave shape, the connection position of two adjacent detection nets 111 corresponds to the peak position or the trough position of the anti-drilling detection cable 16, and the connection position of two adjacent detection nets 111 and the peak position or the trough position of the anti-drilling detection cable 16 are not fixedly connected, in this way, when the intrusion of an access passageway of a harbor by an intrusion object causes the vibration of the portion of the anti-drilling detection cable 16 corresponding to one of the detection nets 111, the peak position or the trough position of the anti-drilling detection cable 16 prevents the vibration of the portion of the anti-drilling detection cable 16 from propagating to the portion of the anti-drilling detection cable 16 corresponding to the adjacent detection net 111, thereby reducing the false alarm rate.
Fig. 9 shows a variant of the detection net 111 of the zoned detection system according to the above preferred embodiment of the invention, unlike the detection net 111 of the zoned detection system shown in fig. 1 to 5, in this particular example of the zoned detection system shown in fig. 9, the upper part of the detection net 111 and the anti-climb detection cable 15 are not fixedly connected by the tie 70, but by a buffer 17, which buffer 17 for connecting the detection net 111 and the anti-climb detection cable 15 is defined as a top buffer, i.e. the top buffer is adapted to connect the detection net 111 and the anti-climb detection cable 15, such that, on the one hand, the top buffer is able to connect the anti-climb detection cable 15 above the detection net 111 to set the anti-climb detection cable 15 to the top of the net assembly 11, and, on the other hand, the top buffer is adapted to be fixedly connected by a buffer 17 for the climbing segment to the anti-climb detection cable 15 to thereby reduce the rate of intrusion into and out of the anti-climb detection cable 15 to the corresponding part of the anti-climb detection cable 15 when the anti-climb detection cable is carried over the corresponding part of the anti-climb detection net 111.
The buffer 17 has elasticity, for example, the buffer 17 may be made of a foaming material, so that, when an access passage of the port is invaded to cause a portion of the anti-climbing detection cable 15 corresponding to one of the detection nets 111 to vibrate, the buffer 17 can absorb the portion of vibration to prevent the portion of vibration from propagating to a portion of the anti-climbing detection cable 15 corresponding to the adjacent detection net 111, thereby reducing a false alarm rate. Opposite sides of the buffer 17 may have a groove 171, respectively, the laterally extending portion 1111 of the probe net 111 being snapped into the groove 171 of one side of the buffer 17, the anti-climb probe cable 15 being snapped into the groove 171 of the other side of the buffer 17 to ensure that the buffer 17 is held between the probe net 111 and the anti-climb probe cable 15. Preferably, the defending and detecting assembly 10 further includes a connecting portion 18, and the connecting portion 18 can connect the laterally extending portion 1111 of the detecting net 111, the anti-climbing detecting cable 15 and the buffering portion 17 in a binding manner, so as to prevent the buffering portion 17 from falling off from between the detecting net 111 and the anti-climbing detecting cable 15.
Accordingly, the lower part of the detection net 111 and the anti-drilling detection cable 16 are not fixedly connected by the tie 70 but fixedly connected by the buffer 17, and for ease of understanding, the buffer 17 for connecting the detection net 111 and the anti-drilling detection cable 16 is defined as a bottom buffer, that is, the bottom buffer is used for connecting the detection net 111 and the anti-drilling detection cable 16, so that, on one hand, the bottom buffer can connect the anti-drilling detection cable 16 below the detection net 111 to set the anti-drilling detection cable 16 at the bottom of the defending net assembly 11, and, on the other hand, the bottom buffer is used for segmenting the anti-drilling detection cable 16, so that when an access passage of a port is invaded to cause a part of the anti-drilling detection cable 16 corresponding to one of the detection nets 111 to vibrate, the bottom buffer prevents the vibration of the part of the anti-drilling detection cable 16 from propagating to the part of the anti-drilling detection cable 16 corresponding to the adjacent part of the anti-drilling detection cable 16 corresponding to the anti-drilling net 111, thereby reducing the false rate.

(d) And judging the invaded position of the access passage of the port according to the received reflected light wave.
In one example of the zonal detection method of the present invention, in the step (a), the anti-climb detection cables 15 are connected above the detection nets 111 to set the anti-climb detection cables 15 on top of the detection nets 111. For example, in one specific example of the zoning detection method of the present invention, the anti-climb detection cable 15 and the upper side of the detection net 111 are fixedly connected by the tie 70 so as to provide the anti-climb detection cable 15 on the top of the detection net 111, and at the same time, in order to reduce the false alarm rate, the anti-climb detection cable 15 is provided with a coil remainder 100 at the connection position of two adjacent detection nets 111. In another specific example of the zoning detection method of the present invention, the upper part of the detection net 111 and the anti-climbing detection cable 15 are fixedly connected through the binding belt 70, so that the anti-climbing detection cable 15 is arranged at the top of the detection net 111, meanwhile, in order to reduce the false alarm rate, the anti-climbing detection cable 15 extends in a wave shape, the connection position of two adjacent detection nets 111 corresponds to the peak position or the trough position of the anti-climbing detection cable 15, and the peak position or the trough position of the anti-climbing detection cable 15 is not fixedly connected with the detection net 111. In another specific example of the partition detection method of the present invention, the side edge of at least one detection net 111 of two adjacent detection nets 111 and the anti-climb detection cable 15 are connected through the top buffer portion, so that not only the anti-climb detection cable 15 can be disposed on the top of the detection net 111, but also the top buffer portion can prevent the vibration of one section of the anti-climb detection cable 15 from propagating to the other section, so as to reduce the false alarm rate.
Accordingly, in the step (a), the anti-drilling detection cables 16 are connected below the detection nets 111 to provide the anti-drilling detection cables 16 at the bottom of the detection nets 111. For example, in one specific example of the zoning detection method of the present invention, the lower portion of the detection net 111 and the anti-drilling detection cable 16 are fixedly connected by the tie 70, so that the anti-drilling detection cable 16 is disposed at the bottom of the detection net 111, and at the same time, in order to reduce the false alarm rate, the anti-drilling detection cable 16 is disposed with a margin 100 at the connection position of two adjacent detection nets 111. In another specific example of the zonal detection method of the present invention, the lower portion of the detection net 111 and the anti-drilling detection cable 16 are fixedly connected by the tie 70 so as to provide the anti-drilling detection cable 16 at the bottom of the detection net 111, meanwhile, in order to reduce the false alarm rate, the anti-drilling detection cable 16 extends in a wave shape, the connection position of two adjacent detection nets 111 corresponds to the peak position or the trough position of the anti-drilling detection cable 16, and the peak position or the trough position of the anti-drilling detection cable 16 and the detection net 111 are not fixedly connected.
