Description

Technical Field

[0001] The invention belongs to the technical field of torpedo launching, and in particular relates to a cable-free torpedo launching tube. Background Art

[0002] Torpedoes are an important maritime force, and their main function is to defend sea power. Torpedoes are usually pre-loaded in torpedo tubes, and then launched through traditional cable parameter settings and instructions. However, this process is cumbersome, requires more human participation, and has a low degree of intelligence.

[0003] To this end, the present invention designs a cable-free torpedo tube. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the current torpedo launching by cable control, such as complicated control process, much human participation and low intelligence, and to provide a cable-free torpedo launching tube.

[0005] The concept of the present invention:

[0006] In order to avoid the inconvenience caused by cable-controlled torpedo launch, the present invention intends to use wireless energy communication technology to perform state switching, pre-setting parameters, and command transmission on torpedoes. Although wireless energy communication technology can realize torpedo launch, considering the special underwater environment, the impact of underwater eddy current loss on energy communication efficiency should also be fully considered, because when wireless energy communication technology is applied to the marine environment, the primary side and the secondary side cannot be completely fitted, and there will be seawater medium between the two. Since the conductivity of seawater is much greater than that of air, the high-frequency alternating current in the coil will generate an alternating electromagnetic field in the seawater, and then generate eddy current loss in the coil coupling area. The eddy current loss will cause energy to be lost in the form of heat, thereby reducing the transmission efficiency of the wireless energy communication system. For this reason, the research team of the present invention believes that at the same time, the problem of turbine loss needs to be solved, and the seawater between the primary side and the secondary side should be discharged to improve the efficiency and reliability of the wireless energy communication system.

The specific method can be selected according to the actual application scenario and requirements.

[0032] Compared with conventional torpedo tube cable operation, the present invention has the following advantages:

[0033] 1. Different from the conventional torpedo tubes which use cables to issue launch commands, the device of the present invention does not require wired contact. Through wireless energy signal transmission, it can realize intelligent power-on and parameter reading of torpedoes, making the torpedo launching process more intelligent; compared with cable-type torpedo tubes, the overall operation is simplified, the laying and maintenance of cables are omitted, and the launch can be faster; the reliability and flexibility are improved, the influence of external interference on signal transmission is reduced, and it is easier to integrate into different types of platforms; the weight is reduced.

On the other hand, it helps to conduct the heat generated by the primary side coil to the external seawater through the thermal insulating oil, thereby improving the working reliability of the primary side coil.

DETAILED DESCRIPTION

[0047] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0048] like Figure 1 As shown, a cable-free torpedo launch tube includes a launch tube body and a wireless energy signal transmission system. The launch tube body is used to install the torpedo to be launched. The wireless energy signal transmission system includes a primary side component and a secondary side component.

[0049] The primary side assembly is installed at the bottom of the launch tube body, including a primary side shell and a primary side module arranged in the primary side shell. The upper end of the primary side shell is an open end, and is provided with a rubber cover (specifically, a silicone cover or a thermoplastic elastomer cover can be used). The rubber cover is adhered to the primary side shell and fastened with a flange, and the two form a sealed oil bag; in the initial state, the sealed oil bag is pre-filled with thermal insulating oil, and its internal oil pressure is set to be equal to the seawater pressure at the depth (on the one hand, it can prevent the seawater pressure from flattening the oil bag and affecting the installation space of the primary side coil, and on the other hand, it can shorten the time to discharge the seawater in the coupling area and improve efficiency), and the lower end is provided with an oil filling and discharging assembly. The secondary side assembly is installed at the bottom of the torpedo to be launched, including a secondary side shell and a secondary side module arranged in the secondary side shell. The secondary side shell is processed by integrated potting molding technology.

[0050] like Figure 2 As shown, the principle of simultaneous signal transmission inside the primary side module and the secondary side module is as follows:

[0051] The primary side module includes a primary side inverter, a primary side LCC-LCC compensation circuit, a primary side MCU, a primary side modulation and demodulation module and a primary side coil; the DC source of the transmitting tube is connected to the input port of the primary side inverter, the output port of the primary side inverter is connected to the input port of the primary side LCC-LCC compensation circuit, and the output port of the primary side LCC-LCC compensation circuit is connected to the primary side coil; wherein a primary side ferrite core is laid under the primary side coil; the primary side MCU is electrically connected to the primary side modulation and demodulation module, and the primary side modulation and demodulation module is connected to the primary side LCC-LCC compensation circuit through a data transmission circuit; the data transmission circuit is composed of a resonant circuit and a primary side coupling transformer;

[0052] The secondary side module includes a secondary side rectifier circuit, a secondary side LCC-LCC compensation circuit, a secondary side MCU, a secondary side modulation and demodulation module and a secondary side coil; the secondary side coil is connected to the input port of the secondary side LCC-LCC compensation circuit, the output port of the secondary side compensation network is connected to the input port of the secondary side rectifier, and the output port of the secondary side rectifier is connected to the electrical device in the torpedo to be launched. The secondary side MCU is electrically connected to the secondary side modulation and demodulation module, and the secondary side modulation and demodulation module is connected to the secondary side LCC-LCC compensation circuit through a data receiving circuit; the data receiving circuit is composed of a filter circuit and a secondary side coupling transformer. The secondary side module is installed as close to the torpedo shell as possible to reduce the wireless power transmission distance and improve the energy transmission efficiency. The primary side module converts the direct current provided by the transmitting tube into high-frequency alternating current; the primary side MCU receives the data signal sent by the computer control terminal through a wire, and the data signal is modulated into a data waveform (such as a sine wave) by the primary side modulation and demodulation module, and then injected into the data sending circuit, and then coupled to the primary side LCC-LCC compensation circuit, and forms a mixed signal with the energy (in this embodiment, the ASK modulation method is adopted to finally inject the digital signal into the primary side LCC-LCC compensation circuit through the data sending circuit); the mixed signal is coupled to the secondary side coil through the alternating electromagnetic field generated by the primary side coil, and the mixed signal is coupled to the secondary side coil through the alternating electromagnetic field generated by the primary side coil, and transmitted through the secondary side LCC-LCC compensation circuit, wherein the data waveform is detected by the data receiving circuit, and the data signal is demodulated and restored by the secondary side modulation and demodulation module (in this embodiment, the data waveform is decoupled by the secondary side coupling transformer, and the data signal is restored to the secondary side modulation and demodulation module through the filtering circuit), and the data signal finally acts on the torpedo to be launched through the secondary side MCU.

[0053] like Figure 3 As shown, in the data transmission circuit on the primary side, U dc is the DC input voltage, Q 1 , Q 2 , Q 3 , Q 4The primary side inverter is composed of R TX is the series resistance, L P1 , L P2 are the self-inductance of the primary and secondary coils of the primary-side coupling transformer, C TX Signal coupling capacitor for data transmission circuit.

[0054] In the data receiving circuit on the secondary side, C d2 is the signal coupling capacitor of the data receiving circuit, L S1 , L S2 are the self-inductance of the primary and secondary coils of the secondary side coupling transformer, R RX is the voltage gain control resistor, R eq is the output resistance.

[0055] Among them, the primary side inductance and capacitance (L f1 , C f1 , C 1 , L 1 ) is much lower than the data carrier frequency. This high-order filter circuit filters out the high-order harmonics in the inverter output voltage. f2 , C f2 , C 2 , L 2 ) filters out the high-order harmonics in the rectifier bridge input voltage and suppresses the high-frequency noise introduced by energy transmission. P2 With C d1 and L S1 With C d2 It resonates at the data carrier and forms a bandpass filter circuit, effectively attenuating the power signal entering the data receiving circuit. 1 , L 2 It is a wave blocking inductor, which ensures that high-frequency data signals can be effectively transmitted, prevents high-frequency data signals from entering other branches, and reduces the attenuation of data signals. P2 , L S1 ) through the high frequency capacitor (C d1 , C d2 ) is connected to the main circuit, and the capacitor plays the role of coupling the high-frequency data carrier and isolating the power carrier. RX It is used to adjust the data signal strength and control the data transmission power consumption. When the data signal changes from 1 to 0, it also passes through the resistor R RX Consume the energy stored in the inductor and capacitor in the system to reduce the signal edge oscillation time and improve signal quality.

[0056] Working principle of wireless simultaneous interpretation system:

[0057] When the torpedo is in the main body of the launch tube, the launch tube receives the switch-on command from the computer control end, and the primary-side MCU receives the power-on command, such as Figure 4 As shown, the oil charging and discharging component is controlled to be turned on, and the primary side shell is filled with oil to squeeze the seawater between the transmitting tube body and the torpedo, thereby reducing the eddy current loss during wireless charging (the digital signal current is small and the transmission distance is short, so the eddy current loss is not considered); at this time, wireless charging is turned on, and the inverter converts the external DC of the transmitting tube into AC and transmits it to the primary side coil through the primary side LCC-LCC compensation circuit. The secondary side rectifies the AC on the secondary side coil through the secondary side LCC-LCC compensation circuit and the rectifier circuit and inputs it to the load of the subsequent stage. The load is then connected to the powered-on servo. At this time, the servo is powered on and closed for power transmission; the secondary side MCU sends a power-on success data indication through the secondary side modulation and demodulation module, and the data waveform is transmitted to the primary side through the secondary side coupling transformer, and then the data signal is parsed with the primary side modulation and demodulation module after data decoupling and filtering by the primary side coupling transformer; at the same time, the primary side MCU sends a query instruction to read the torpedo status parameters, including battery SOC, various sensor parameters, etc.

[0058] like Figure 5 As shown, when the primary side shell and the secondary side shell are initially matched, the sealing oil bag is separated from the secondary side shell, and seawater exists in the coupling area between them. After the sealing oil bag is filled with oil through the oil filling and discharging assembly, the sealing oil bag will gradually expand and gradually fit with the secondary side shell, and the seawater in the coupling area will be discharged.

[0059] The oil filling and discharging assembly is arranged at the lower end of the primary side housing and is connected to the sealing oil bag. The oil filling and discharging assembly can be used to fill the sealing oil bag with thermal insulation oil to expand the rubber cover on the upper part outward, and discharge the thermal insulation oil 12 from the sealing oil bag to restore the deformation of the rubber cover on the upper part.

[0060] In this embodiment, the oil filling and discharging assembly includes an oil storage tank cover, an oil storage tank body, a pump, a first inner conduit, a first flow valve, a second inner conduit, a first solenoid valve and a first outer conduit connected in sequence, and a control module for controlling the pump, the first flow valve and the first solenoid valve (the control module belongs to the prior art and is not shown in the figure). The oil storage tank cover is arranged at the upper end of the oil storage tank body and is statically sealed by a sealing ring to form a sealed oil storage tank, in which heat-conducting insulating oil (such as transformer oil, etc.) is stored; the pump, the first inner conduit, the first flow valve, the second inner conduit and the first solenoid valve are located inside the oil storage tank body, and the first outer conduit is located outside the oil storage tank body. The primary side housing is connected to the oil storage tank body through the first outer conduit. The oil inlet and outlet are located below the pump housing.

[0061] The control principle of the oil filling and discharging assembly is: the control module can realize the mode switching of filling and discharging by controlling the forward and reverse mode switching of the pump, the opening and closing of the oil circuit can be realized by controlling the first solenoid valve, and the filling and discharging rate can be adjusted by controlling the first flow valve.

[0062] The voltage pulse generated by the primary side coil is kept unchanged, and the control module monitors the voltage pulse peak value generated by the secondary side coil in real time. As the sealing oil bag gradually expands, the seawater in the coupling area is gradually discharged. During this process, the eddy current loss in the coupling area gradually decreases, so the voltage pulse peak value generated by the secondary side coil gradually increases. When the control module monitors that the voltage pulse peak value generated by the secondary side coil no longer changes, the eddy current loss has been reduced to the minimum, indicating that the sealing oil bag is completely fitted with the secondary side shell and no further oil filling is required. The control module can control the action of the first solenoid valve to close the oil circuit, and calculate the current oil filling amount through the flow rate of the first flow valve and the oil filling time.

[0063] When draining the oil, the control module calculates the drain flow rate in real time based on the flow rate of the first flow valve and the drain time. When the drain flow rate is equal to the oil filling amount, it indicates that the sealed oil bag has returned to its initial state. At this time, the control module can close the oil circuit by controlling the action of the first solenoid valve.

[0064] The working principle of the oil filling and discharging assembly in this embodiment is as follows:

[0065] When the torpedo to be launched is installed inside the launch tube body, the pump and the first solenoid valve are turned on through the control module, and the thermally conductive insulating oil enters the pump from the oil storage tank through the oil inlet and outlet, and then enters the sealed oil bag through the first inner conduit, the first flow valve, the second inner conduit, the first solenoid valve and the first outer conduit in sequence. During the oil filling process, the pressure inside the sealed oil bag gradually increases. When the internal pressure of the sealed oil bag is greater than the external water pressure, the rubber cover begins to expand outward. Under the squeeze of the rubber cover, the seawater medium between the primary side coil and the secondary side coil gradually decreases. When the rubber cover is completely fitted with the secondary side shell, the pump and the first solenoid valve are closed to end the oil filling. At this time, the seawater medium in the coupling area between the primary side coil and the secondary side coil is basically emptied, and efficient wireless charging can be achieved. The schematic diagram after the coil is filled with oil and the rubber cover is completely fitted with the secondary side shell is shown as follows. Figure 6 shown.

[0066] When the torpedo leaves the launch tube body, the pump and the first solenoid valve are turned on to drain the oil from the sealed oil bag. The thermally conductive insulating oil in the sealed oil bag flows back and is stored in the oil storage tank after passing through the first outer conduit, the first solenoid valve, the second inner conduit, the first flow valve, the first inner conduit and the pump. The sealed oil bag gradually recovers its deformation, and the rubber cover gradually separates from the secondary side shell.

[0067] During this period, adjusting the first flow valve can control the speed of oil filling and oil draining. The oil filling speed should ensure that the underwater equipment will not shake due to excessively fast oil filling speed, while there is no special requirement for the oil draining speed to be too fast or too slow.

[0068] Effect verification:

[0069] Figure 7 It is the eddy current loss in the coil coupling area before and after the sealing oil bag is filled with oil in this embodiment. As can be seen from Figure (a), the eddy current loss before oil filling is mainly concentrated in the seawater area between the primary side coil and the secondary side coil. As can be seen from Figure (b), the eddy current loss between the primary side coil and the secondary side coil is eliminated after oil filling. Only the eddy current loss caused by the stray electromagnetic field exists outside the coil. The loss density and loss area of ​​this part are small, which has little effect on the transmission efficiency of energy and data signals.

[0070] Of course, the above-mentioned oil filling and discharging group can also be replaced with an air filling and discharging component, and the primary side shell and the deformable medium storage bag can be replaced with a split design, which can achieve the same effect as the above-mentioned embodiment.

[0071] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
