Abstract

The utility model relates to a deepwater net-box with a net damage alarm function, which comprises a net frame, a net which is arranged around the net frame and is formed by surrounding of a plurality of net plates, a balancing weight of the net frame, and a monitoring system having the net damage alarm function, wherein the monitoring system is composed of a signal sending device and a signal receiving device. Net wires of the net plates are added with metal wires with insulation protecting layers; the trend of the metal wires is the same with that of the net braiding method of a common net; ends of the metal wires on the net along longitudinal braiding direction is in parallel connected together and sealed by glue according to the partitions of the net plates; two ends a and b of the metal wire are respectively connected to one end of the signal sending device; each metal wire on the other end of the metal wire is sealed by the glue; the signal sending device is also inserted with an electrode inserting into water. The utility model takes seawater as a conducting body. When the net is not damaged, circuits are not switched on; when the net is damaged, the loop current is formed by that the current flow flows through the seawater. The signal sending device sends code signals of corresponding positions out after the signal receiving device receives the code signal. The code signal corresponding to the damaged position or the fault position of the net is displayed by decoding, and then the alarm signal is sent out.

Description

Deep water mesh cage with etting breakage alarm function

Technical field

The utility model relates to the deep water mesh cage with etting breakage alarm function.

Background technology

Deep water mesh cage can not in time be found to cause the fish in the case and escapes in a large number owing to the etting breakage, the raiser is brought about great losses, thereby restricted the development of cage culture, and use at present in water with the method for optics shooting light, the ir supervisor that can in water, work commonly used, then surveillance needs long-time non-stop run, energy consumption is big, and if in mixing water then optical system do not prove effective, if with the bigger investment of needs just of sonar method, impracticable.Cause the etting breakage to happen occasionally owing to a variety of causes at present, if can in time find the etting breakage, and adopt an effective measure, the economic loss of bringing by the fish escape then can significantly be reduced.Also there is not at present a kind of net cage that can be used for the damaged real-time detection of deep water net cage net clothing.

Summary of the invention

The purpose of this utility model provides a kind of deep water mesh cage with etting breakage alarm function, in case disrumpent feelings the warning immediately of etting knows that in time the etting damage location can repair.

For achieving the above object; the technical solution adopted in the utility model is as follows: it comprises rack; be contained in the etting that rack is surrounded by several pieces net sheets on every side; the rack balancing weight; the monitoring system of the etting breakage alarm function of forming by signal projector and signal receiver; the plain conductor that in the netting twine of net sheet, adds the tape insulation protective layer; the trend of plain conductor and the identical net of conventional braiding method; end along the plain conductor on the braiding longitudinal direction etting is connected in parallel by net sheet subregion; seal with the sea water resistance fluid sealant again; its two end a; b is connected on an end of signal projector respectively; the other end along the plain conductor on the braiding longitudinal direction etting; every plain conductor is sealed with the sea water resistance fluid sealant, also is connected to insertion electrode under water on signal projector.

The beneficial effect that the utlity model has is: it is conductor with the seawater, not conducting of circuit when net is not broken, electric current became the loop by seawater through electrode conduction when net was broken, signal projector sends the code signal of corresponding site, signal receiver is received code signal, demonstrate the etting breakage or the line fault position signalling of corresponding site through decoding, and send alarm signal.The utility model can significantly reduce owing to the etting breakage, the economic loss that causes fish to escape and bring.

Embodiment

As Fig. 1; shown in Figure 2; it comprises rack 2; be contained in the etting 1 that rack 2 is surrounded by several pieces net sheets 7 on every side; rack balancing weight 6; the monitoring system of the etting breakage alarm function of forming by signal projector 3 and signal receiver 4; the plain conductor that in the netting twine of net sheet 7, adds the tape insulation protective layer; the trend of plain conductor and the identical net of conventional braiding method; end along the plain conductor on the braiding longitudinal direction etting 1 is connected in parallel by net sheet 7 subregions; seal with the sea water resistance fluid sealant again; its two end a; b is connected on an end of signal projector 3 respectively; the other end along the plain conductor on the braiding longitudinal direction etting 1; every plain conductor is sealed with the sea water resistance fluid sealant, also is connected to insertion electrode 5 under water on signal projector 3.The trend of the said plain conductor net identical with conventional braiding method be not for having knot prismatic net or not having knot hexagon net or do not have the tying-in netting or knot prismatic net or knotless joining net are arranged.

As shown in Figure 4, rack is the polygon rack, forms to cover polygon floating type net cage A or uncovered polygon floating cage B.

As shown in Figure 5, rack is a circular net, and forming has circular floating type net cage C of lid or the circular floating cage D of uncovered.

When Fig. 2 represents that net sheet 7 breaks normal condition, non-conductive, when Fig. 3 represents 7 breakages of net sheet, the netting twine of arbitrary place lead disconnects on the net sheet 7, then electric current conducting by seawater, electrode 5, connect warning circuit, send alarm signal in wireless or wired mode then, lead on the etting 1 is formed a net sheet 7 of pressing the certain way parallel connection, in case any one is by disconnected on the net sheet 7, then electric current forms a path by seawater, and alarm circuit is worked, and know net sheet 7 damage locations, take measures to repair.
