Description
Technical Field
The invention relates to an underwater signal generating and receiving device, in particular to a detection net and a manufacturing method thereof.
Background
The optical fiber network is an important component of the port defense system, which provides not only a physical interception function but also an intrusion detection function. In other words, when an intrusion object intrudes into the access way of the port, the optical fiber network intercepts the intrusion object to prevent the intrusion object from entering and exiting the port, and at the same time, the specific position of the intrusion object in the access way of the port can be detected according to the light waves reflected by the optical fiber network due to vibration. The braiding method of the optical fiber network in the prior art is cross braiding in the horizontal and vertical directions, for example, in the chinese patent application publication No. CN115976731a, an optical fiber network is disclosed, and the braiding steps include: firstly, allowing a complete optical fiber cable to sequentially bypass each first guide wheel of two rows of first direction guide wheel groups spaced from each other to form a warp yarn section by the optical fiber cable between the first guide wheel of one row of the first direction guide wheel groups and the first guide wheel of the other row of the first direction guide wheel groups, secondly, allowing the optical fiber cable to sequentially bypass each second guide wheel of two rows of second direction guide wheel groups spaced from each other to form a weft yarn section by the optical fiber cable between the second guide wheel of one row of the second direction guide wheel groups and each second guide wheel of the other row of the second direction guide wheel groups, wherein each weft yarn section is parallel to each other, wherein each weft yarn section is positioned above each warp yarn section in a plan view, and the extending direction of the weft yarn section and the extending direction of the warp yarn section are perpendicular to each other, and thirdly, allowing a locking device to lock the warp yarn section and the weft yarn section at the crossing position of the warp yarn section and the weft yarn section to weave the optical fiber net. The optical fiber network in the prior art generally determines the impact resistance level according to the self tensile strength of the warp segments, the weft segments and the locking device when being resistant to the impact of an intrusion object, the impact force generated by the intrusion object when impacting the optical fiber network is fully absorbed by the optical fiber cable and the locking device, and the optical fiber cable directly breaks down as a whole when the impact force exceeds any one of the self strength limit of the optical fiber cable and the self strength limit of the locking device.

A port defense system according to a preferred embodiment of the present invention, including a first winch 100, a second winch 200, a traction cable 300, and a net assembly 400, will be disclosed and described in the following description with reference to fig. 1 through 13 of the drawings accompanying the present specification.
The first winch 100 and the second winch 200 are respectively disposed at opposite sides of the port access way, for example, referring to fig. 1, opposite sides of the port access way are respectively constructed with concrete bases, the first winch 100 is mounted at the concrete base of one side of the port access way, and the second winch 200 is mounted at the concrete base of the other side of the port access way, so as to respectively dispose the first winch 100 and the second winch 200 at opposite sides of the port access way. One end of the hauling cable 300 is operatively connected to the first winch 100, the other end is operatively connected to the second winch 200, the first winch 100 is configured to perform a reeling and unreeling operation on the hauling cable 300, and the second winch 200 is configured to perform a reeling and unreeling operation on the hauling cable 300.
The net assembly 400 includes a plurality of probe nets 10, a plurality of buoyancy sections 20, and a plurality of connection cables 30, the probe nets 10 are sequentially spliced, the outer side of one of the probe nets 10 adjacent to the first winch 100 is disposed to be maintained with respect to the position of the first winch 100, the outer side of one of the probe nets 10 adjacent to the second winch 200 is disposed to be fixedly connected to the traction cable 300, the top of each of the probe nets 10 is respectively provided with at least one of the buoyancy sections 20, and adjacent ones of the buoyancy sections 20 are connected by the connection cables 30.
The first winch 100 and the second winch 200 cooperate with each other to unwind and retract the net assembly 400 via the pull cable 300. When the first winch 100 and the second winch 200 are mutually matched to unwind the net assembly 400 through the hauling cable 300, the buoyancy parts 20 of the net assembly 400 provide buoyancy for suspending the spliced detecting nets 10 in a water area of a port access passage, so that the detecting nets 10 close the port access passage, and prevent a ship or the like from entering and exiting the port through the port access passage. When the first winch 100 and the second winch 200 are mutually matched to fold the net assembly 400 by the pulling rope 300, the buoyancy parts 20 of the net assembly 400 provide buoyancy for suspending the spliced detecting net 10 in a water area on the shore of the port, so as to open an access way of the port, and allow a ship or the like to access the port through the access way of the port.
In particular, with reference to fig. 4 to 6, the detection net 10 comprises a plurality of transversal extensions 11 and a plurality of locking means 12 and has a plurality of rows of meshes 13. Adjacent said lateral extensions 11 are joined end to end, for example, in this particular example of said port defence system of the present invention, said lateral extensions 11 of said detection net 10 are made of one complete cable 1000, so that adjacent said lateral extensions 11 can be joined end to end. Each of the laterally extending portions 11 has a plurality of locking positions 111, respectively, and the locking means 12 locks the locking position 111 of one of the laterally extending portions 11 and the locking position 111 of an adjacent one of the laterally extending portions 11 to form the mesh openings 13 between the adjacent laterally extending portions 11, wherein the locking position 111 of one of the laterally extending portions 11 is adjacent to the locking position 111 of one of the laterally extending portions 11 on one side of the laterally extending portion 11 and is offset from the locking position 111 of one of the laterally extending portions 11 on the other side of the laterally extending portion 11, such that the detection net 10 can form a plurality of rows of the mesh openings 13, and the plurality of rows of the mesh openings 13 are distributed along the width direction of the detection net 10.
With such a structure, when an intruded object hits the detecting net 10, the detecting net 10 can be extended in the width direction and contracted in the height direction, so that the detecting net 10 provides a good buffer space, the time during which the detecting net 10 is impacted is prolonged, so that the impact resistance of the detecting net 10 is not limited by the strength limit of the optical fiber and the locking device 12 itself any more, and the impact resistance level of the detecting net 10 is improved, which is important for ensuring the safety of the access passage of the port.
Meanwhile, the length of the cable 1000 used to make the detection net 10 of the present invention is shorter than that of the detection net of the prior art, so that, in the first aspect, the detection net 10 of the present invention has lower cost with the same protection area, for example, when the length-width dimension of the detection net 10 is 3m×17m, the length of the optical fiber required for the detection net woven in a horizontal and vertical cross-woven manner according to the prior art is 600m-700m, and the length of the cable 1000 required for the detection net 10 of the present invention is 400m-500m; in the second aspect, the detecting net 10 of the present invention has a smaller volume in the storage state, which can not only reduce the storage cost and the transportation cost of the detecting net 10, but also greatly reduce the construction cost of the port, in particular, since the detecting net 10 has a smaller volume in the storage state, the concrete bases on the opposite sides of the access way of the port can be smaller, thus not only reducing the construction cost, but also reducing the construction difficulty; in a third aspect, the detecting net 10 of the present invention has a smaller dead weight, which makes the buoyancy section 20 only provide a smaller buoyancy force to suspend the detecting net 10 in the water area of the port access passage, thereby facilitating the cost reduction and flexibility improvement of the port defense system.
Specifically, when the intrusion object impacts the detection net 10, the calculation formula of the instantaneous impact force is as follows:wherein, the parameter m is the mass of the intruded object, and the parameter V t For the speed of the intrusion object after being intercepted by the detecting net 10, wherein if the detecting net 10 effectively intercepts the intrusion object (Kg), the speed of the intrusion object after being intercepted by the detecting net 10 can be regarded as V t =0m/s, parameter V 0 For initial velocity (m/s) of an intruding object, the parameter t is when the detection net 10 is impactedAnd (3) the room(s). It follows that, in the case of the mass (m) and the initial velocity (V) of the intruding object 0 ) In the fixed case, it is necessary to lengthen the impact time of the detection net 10 in order to effectively reduce the instantaneous impact force. In the port defense system of the present invention, since the locking position 111 of one of the laterally extending portions 11 of the detecting net 10 is adjacent to the locking position 111 of one of the laterally extending portions 11 located at one side of the laterally extending portion 11 and is offset from the locking position 111 of one of the laterally extending portions 11 located at the other side of the laterally extending portion 11, when an intruded object hits the detecting net 10, the detecting net 10 can be extended in the width direction and contracted in the height direction so that the detecting net 10 provides a good buffering space, the time for which the detecting net 10 is impacted is prolonged, so that the impact resistance of the detecting net 10 is no longer limited by the strength limits of the cable 1000 and the locking device 12 itself, and the impact resistance level of the detecting net 10 is improved. Also, since the buoyancy provided by the buoyancy section 20 providing buoyancy above the detecting net 10 is reduced, when an invading object hits the detecting net 10 to extend the detecting net 10 in the width direction and contract in the height direction, the buoyancy section 20 can be timely pulled down by the detecting net 10 to increase the response speed of the harbor defense system, which is essential for securing the safety of the ingress and egress path of the harbor.
In one example of the port defense system of the present invention, the nth of the locking positions 111 of one of the laterally extending portions 11 of the detecting net 10 and the nth of the locking positions 111 of one of the laterally extending portions 11 located on one side of the one of the laterally extending portions 11 are locked by the locking means 12, the mth of the locking positions 111 and the mth of the locking positions 111 of one of the laterally extending portions 11 located on the other side of the one of the laterally extending portions 11 are locked by the locking means 12 to form the mesh 13 between the adjacent two of the laterally extending portions 11, where N is an odd number and M is an even number, such that the locking positions 111 of one of the laterally extending portions 11 are adjacent to the locking positions 111 of one of the laterally extending portions 11 located on the one side of the one of the laterally extending portions 11 and are offset from the locking positions 111 of the one of the laterally extending portions 11 located on the other side of the one of the laterally extending portions 11.

In this particular example of the port defense system of the present invention, referring to fig. 4 and 5, the plurality of the laterally extending portions 11 of the detection net 10 are waved, the locking positions 111 of the laterally extending portions 11 are located at peak positions or valley positions of the laterally extending portions 11, and one of the peak positions of the laterally extending portions 11 and the valley positions of the adjacent laterally extending portions 11 are locked by the locking means 12 to form the mesh holes 13 between the adjacent laterally extending portions 11. Alternatively, in some optional examples of the port defense system according to the present invention, the topmost one of the laterally extending portions 11 and the bottommost one of the laterally extending portions 11 may be horizontally extending, wherein the locking position 111 of the topmost one of the laterally extending portions 11 and the locking position 111 of the laterally extending portion 11 adjacent to the one of the laterally extending portions 11 at the peak position are fixed by the locking means 12, and the locking position 111 of the bottommost one of the laterally extending portions 11 and the locking position 111 of the laterally extending portion 11 adjacent to the one of the laterally extending portions 11 at the valley position are fixed by the locking means 12.
By allowing these laterally extending portions 11 to extend in a wavy shape and locking the peak position of one laterally extending portion 11 and the valley position of the adjacent laterally extending portion 11, the detecting net 10 is provided with a buffer space, so that when an intruded object hits the detecting net 10, the detecting net 10 can be extended in the width direction and contracted in the height direction, so that the detecting net 10 provides a good buffer space, the time during which the detecting net 10 is hit is prolonged, so that the impact resistance of the detecting net 10 is no longer limited by the strength limits of the cable 1000 and the locking device 12 itself, improving the impact resistance level of the detecting net 10, which is critical to ensure the safety of the access port.
In one example of the port defense system of the present invention, referring to fig. 4 and 5, the probe net 10 includes a longitudinally extending portion 14, the bottom of the longitudinally extending portion 14 is connected to one of the laterally extending portions 11 at the bottom, and the top of the longitudinally extending portion 14 extends to a position beyond one of the laterally extending portions 11 at the top, in such a manner that when two of the probe nets 10 are spliced, the end of the longitudinally extending portion 14 of one of the probe nets 10 (i.e., the top of the longitudinally extending portion 14) and the head end of the laterally extending portion 11 at the top of one of the probe nets 10 spliced therewith (i.e., the end of the laterally extending portion 11 at the top that is not connected to the end adjacent to the laterally extending portion 11) are connected so as to connect the end of the longitudinally extending portion 14 of one of the probe net 10 and the head end of the laterally extending portion 11 of the probe net 10 spliced therewith, thereby splicing the two of the probe nets 10 in series.
In a specific example of the port defense system according to the present invention, referring to fig. 3, the longitudinally extending portions 14 sequentially penetrate through the outermost row of the mesh holes 13 of the probe net 10, so that the probe net 10 can be conveniently received and transported when the two probe nets 10 are not spliced, the side edges of the adjacent two probe nets 10 can be overlapped when the two probe nets 10 are spliced, and the longitudinally extending portions 14 of one probe net 10 are allowed to sequentially penetrate through the mesh holes 13 of the adjacent two probe nets 10, that is, the longitudinally extending portions 14 of one probe net 10 splice the two probe nets 10 in a "needle penetrating" manner, the probe net 10 according to the present invention allows one cable 1000 to be further increased on the basis of a lock catch to increase the strength of the spliced position of the adjacent two probe nets 10, and the reliability of the port defense system to be improved, compared with the lock catch only.
In one example of the port defense system of the present invention, referring to fig. 7 to 13, the locking device 12 includes a bottom case 121 and a top cover 122 and has two spaced threading holes 123 formed between the bottom case 121 and the top cover 122, one of the locking positions 111 of one of the laterally extending portions 11 is held at one of the threading holes 123 of the locking device 12, one of the locking positions 111 of the adjacent laterally extending portions 11 is held at the other of the threading holes 123 of the locking device 12, for example, the locking position 111 of the peak position of one of the laterally extending portions 11 is held at one of the threading holes 123 of the locking device 12, and the locking position 111 of the trough position of the adjacent laterally extending portion 11 is held at the other of the threading holes 123 of the locking device 12, so that the locking device 12 is used for the adjacent two of the laterally extending portions 11. Unlike the prior art cross-shaped locking device, the locking device 12 of the detecting net 10 locks two adjacent lateral extending portions 11 only in the horizontal direction, which not only facilitates the manufacturing of the detecting net 10, but also does not cause the problem of fiber breakage caused by the fact that the locking device 12 excessively presses the crisscrossed optical fibers.
Specifically, the bottom case 121 has two bottom case grooves 1211 spaced apart from each other, the top cover 122 has two top case grooves 1221 spaced apart from each other, the top cover 122 and the bottom case 121 are installed in such a manner that the top case grooves 1221 and the bottom case grooves 1211 correspond to each other, so that one of the threading holes 123 of the locking device 12 is formed by one of the bottom case grooves 1211 of the bottom case 121 and one of the top case grooves 1221 of the top cover 122, and the other of the threading holes 123 of the locking device 12 is formed by the other of the bottom case grooves 1211 of the bottom case 121 and the other of the top case grooves 1221 of the top cover 122. The locking position 111 of the peak position of one of the laterally extending portions 11 is held at one of the threading holes 123 of the locking device 12, and the locking position 111 of the valley position of the adjacent one of the laterally extending portions 11 is held at the other one of the threading holes 123 of the locking device 12, so that the locking device 12 locks the adjacent two of the laterally extending portions 11.
It should be noted that the installation manner of the bottom case 121 and the top cover 122 is not limited in the port defense system of the present invention.

Preferably, the bottom case 121 and the top cover 122 may be made of rubber material, which allows the bottom case 121 and the top cover 122 to be slightly deformed to increase friction between the bottom case 121 and the cable 1000 and between the top cover 122 and the cable 1000, on the basis of avoiding the cable 1000 from being broken, so that the locking device 12 can reliably lock the locking positions 111 of the adjacent two laterally extending portions 11.
