[0047] In order to better understand the technical solutions of the present application, the present application will be described in detail below with reference to the accompanying drawings.
[0048] The present application provides a self-reaction delay alarm device, which comprises a self-reaction electric energy device 1 and an alarm device 2. The device is applied to a temporary blind plate for ships, and is used to remind the staff to timely remove the temporary blind plate arranged between the opposite connecting pipelines after the pipeline tightness test of the ship is completed.
[0049] Specifically, the self-reaction electric energy device 1 is used to spontaneously react with an electrolyte solution to generate an electric current, and to supply power to the alarm device 2. The two electrodes of the self-reaction electric energy device 1 are connected to the alarm device 2 through wires. When the self-reaction electric energy device 1 reacts with the electrolyte solution for a period of time (i.e. the specific time described above), the alarm device 2 will start to alarm, achieving the effect of delay alarm, so as to remind the staff to timely remove the temporary blind plate after the pipeline tightness test is completed, avoiding the temporary blind plate left in the pipeline.
[0050] The self-reaction electric energy device 1 comprises two upper and lower distance-keeping plates 1.1, an electrolysis shell 1.2 arranged between the upper and lower distance-keeping plates 1.1, an electrolysis assembly arranged in the electrolysis shell 1.2, both ends of the electrolysis assembly respectively extending out of the upper and lower distance-keeping plates 1.1 and connected with an alarm device 2 arranged outside through wires, and a plurality of flow-through holes 1.7 are formed in the electrolysis shell 1.2 to allow electrolyte solution to flow into the electrolysis shell 1.2.
[0051] The electrolysis assembly comprises a first metal substrate 1.3, a second metal substrate 1.4 and a metal foil 1.5. The first metal substrate 1.3 is fixed to the inner side of the upper distance-keeping plate and the end of the first metal substrate 1.3 extends out of the distance-keeping plate and is connected with the wire (i.e. the electrode of the first metal substrate 1.3 extends out of the shell of the self-reaction electric energy device), the second metal substrate 1.4 is fixed to the inner side of the lower distance-keeping plate and the end of the second metal substrate 1.4 also extends out of the distance-keeping plate and is connected with the wire 5 (i.e. the electrode of the second metal substrate 1.4 also extends out of the shell of the self-reaction electric energy device). The metal foil 1.5 is arranged vertically and one end of the metal foil 1.5 is directly physically connected with the first metal substrate 1.3 and the other end of the metal foil 1.5 is directly physically connected with the second metal substrate 1.4, the material of the metal foil 1.5 is different from the materials of the first metal substrate 1.3 and the second metal substrate 1.4 and the metal foil 1.5 is the most active, and the thickness of the metal foil 1.5 is far less than the thicknesses of the first metal substrate 1.3 and the second metal substrate 1.4.
[0052] Suppose the first metal substrate 1.3 is the anode and the second metal substrate 1.4 is the cathode, in this way, the metal attribute of the metal foil 1.5 is more active than the first metal substrate 1.3 and the metal attribute of the first metal substrate 1.3 is more active than the second metal substrate 1.4 (for example, the first metal substrate is zinc plate, the second metal substrate is copper plate, and the metal foil is magnesium). When the electrolyte solution flows into the electrolysis shell 1.2 from the flow-through holes 1.7, the metal foil 1.5 first undergoes oxidation reaction, since the metal foil 1.5 is directly physically connected with the first metal substrate 1.3 and the second metal substrate 1.4, an internal short circuit path is formed between the first metal substrate 1.3 and the second metal substrate 1.4, and the electrons which should flow through the external circuit directly flow from the first metal substrate 1.3 to the second metal substrate 1.4 through the metal foil 1.5, so the actual output voltage of the self-reaction electric energy device 1 is close to 0 and the alarm device 2 does not start and does not alarm; when the metal foil 1.5 is completely consumed, the first metal substrate 1.3 becomes the anode again and continues to provide electrons to the external circuit, while the second metal substrate 1.4 continues to be the cathode and accepts the electrons and undergoes reduction reaction, the actual output voltage of the self-reaction electric energy device 1 becomes the value determined by the standard electrode potential difference of the first metal substrate 1.3 and the second metal substrate 1.4, and the alarm device 2 starts and alarms.
[0053] Therefore, the self-reaction electric energy device 1 will undergo two-stage chemical reactions, the first stage of which is the consumption of the metal foil 1.5, and the duration of which is not less than the total duration of the operation of the temporary blind plate installation and pipeline tightness test for ships, and the second stage of which is the consumption of the first metal substrate 1.3.
[0054] By controlling the duration of the consumption of the metal foil 1.5, the delay start time of the alarm device 2 can be controlled. For example, the consumption speed of the metal foil 1.5 can be accelerated by forming an adjusting punch hole 1.6 that penetrates the foil body in the center of the metal foil 1.5, thereby reducing the delay start time of the alarm device 2.
[0055] Further, the delay start time of the alarm device 2 can be further adjusted by adjusting the aperture of the adjusting punch hole 1.6. Of course, other ways can also be used to control the delay start time of the alarm device 2.
[0056] The above-mentioned electrolytic assembly can be integrally injection molded, and after being manufactured, it is assembled with the distance-keeping plate 1.1 and the electrolytic shell 1.2 into the self-reaction electric energy device 1, and then is packaged in the patch; or the self-reaction electric energy device can also be integrally injection molded, and then is packaged in the patch body 1.
[0057] In one embodiment, the self-reaction electric energy device 1 and the alarm device 2 are arranged in the interior of the same patch, but the self-reaction electric energy device 1 is arranged in a separate chamber in the interior of the patch, and the alarm device 2 is located outside the chamber, and the two electrodes of the self-reaction electric energy device 1 respectively extend out of its shell and the separate chamber, and then are connected with the alarm device 2 through wires.
[0058] In another embodiment, the self-reaction electric energy device 1 and the alarm device 2 can be arranged in different patches, that is, the self-reaction electric energy device 1 is arranged in a first patch 3, and the two end portions of the electrolytic assembly thereof are connected with wires embedded in the first patch 3, and a first patch electrode 5 is arranged at a position on the first patch 3 corresponding to the end of the wire thereof; the alarm device 2 is arranged in a second patch 4, and the power supply end thereof is connected with wires embedded in the second patch 4, and a second patch electrode 6 is also arranged at a position on the second patch 4 corresponding to the end of the wire thereof, and when the first patch 3 and the second patch 4 are fixed, the first patch electrode 5 and the second patch electrode 6 are attached, so that the current generated by the self-reaction electric energy device 1 can be transmitted to the alarm device 2 through the contact between the two patch electrodes. The first patch 3 and the second patch 4 can be fixed by pasting, or can be fixed by other ways. The patch electrodes on the first patch 3 and the second patch 4 can be arranged in front of and behind each other, so as to facilitate the correct installation by the on-site workers.
[0059] The first patch 3 and the second patch 4 are both made of plastic.
[0060] The alarm device 2 comprises an audible and visual alarm 2.1, which is used to give audible and visual alarm to remind the staff to timely remove the temporary blind plate after the pipeline tightness test is finished, so as to avoid that the temporary blind plate is left in the pipeline.
[0061] In another preferred embodiment, the alarm device 2 further comprises an alarm control circuit, which comprises a resistor 2.2, a first triode 2.3 and a second triode 2.4. One end of the resistor 2.2 is connected to one end of the audible and visual alarm 2.1 in parallel, and the other end of the resistor is connected to the collector of the first triode 2.3 and the base of the second triode 2.4. The base of the first triode 2.3 is connected to the collector of the second triode 2.4. The emitter of the first triode 2.3 is connected to the other end of the audible and visual alarm 2.1. The emitter of the second triode 2.4 is connected to the cathode of the electrolytic assembly (such as the end of the second metal base plate 1.4). In this embodiment, the first triode 2.3 is a PNP type triode, and the second triode 2.4 is an NPN type triode.
[0062] In actual use, the self-reaction delay alarm device of the present application is fixedly attached to the temporary blind plate. When the marine temporary blind plate is installed between two flanges of two pipelines that are to be connected, the electrolyte solution enters the self-reaction power device 1 to perform chemical reaction in a certain manner during the process of tightening the flange bolts, and the alarm device 2 gives alarm to prompt the removal of the marine temporary blind plate after a certain time, and the length of the certain time is greater than the total operation time of the installation of the marine temporary blind plate and the pipeline tightness test.
[0063] The manner in which the electrolyte solution enters the self-reaction power device 1 is not the protection content of the present application, but it can be realized in a certain manner, for example, as shown in Figure 1 The electrolyte solution 8 can be packaged in the inner hollow blind plate patch 7, and the blind plate patch 7 is fixedly attached to the first patch 3 of the present application as a whole or integrally manufactured. The blind plate patch 7 is integrally attached to the temporary blind plate 9. When the temporary blind plate 9 is installed between two flanges of two pipelines that are to be connected, the electrolyte solution in the blind plate patch will be squeezed to break the packaging film and enter the self-reaction power device 1 due to the extrusion force during the process of tightening the flange bolts, and chemical reaction is performed and alarm is given to prompt the removal of the marine temporary blind plate after a certain time, and the length of the certain time is greater than the total operation time of the installation of the marine temporary blind plate and the pipeline tightness test.
[0064] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present application.
