Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to an ambient temperature compensation audible and visual alarm patch. Background Technology

[0002] Currently, before conducting a tightness test on marine segmented piping, a temporary blind flange must be installed between two opposing pipe flanges to isolate the piping, ensure tightness pressure, and prevent tightness pressure leakage through the flanges. After the tightness test is completed, the temporary blind flange must be removed from the piping.

[0003] However, in actual construction, due to the complex operating conditions of the pipeline system, construction workers often forget to remove the temporary blind flange, leaving it inside the pipeline. This can cause the temporary blind flange to blindly disconnect the pipeline, resulting in blockage of the medium inside the pipeline, affecting the normal use of the pipeline and leading to quality accidents. For example, in environments where it is difficult to construct, such as cooling water pipelines for marine main and auxiliary engines, pipelines in the deck overhang area, or confined spaces, if the pipeline is blindly disconnected, it will directly cause the marine equipment to overheat, shut down, or be damaged. Summary of the Invention

[0004] In view of this, the present invention provides an ambient temperature compensation sound and light alarm patch to solve the problems existing in the above-mentioned background art.

[0005] An ambient temperature compensation audible and visual alarm patch includes the patch, a self-reactive power device and an alarm device disposed inside the patch, and an isolation seal attached to the patch.

[0006] The self-reactive power supply device is used to power the alarm device. An independent reaction chamber is isolated inside the patch. The self-reactive power supply device is located inside the reaction chamber, and the alarm device is located outside the reaction chamber.

[0007] The alarm device includes an audible and visual alarm and an ambient temperature compensation alarm circuit. The ambient temperature compensation alarm circuit includes a high-temperature positive terminal, a low-temperature positive terminal, and a negative terminal. The high-temperature positive terminal is connected to the anode of the self-reactive power device through a first wire inside the embedded patch, the low-temperature positive terminal is connected to the anode of the self-reactive power device through a second wire inside the embedded patch, and the negative terminal is connected to the cathode of the self-reactive power device through a third wire inside the embedded patch. Both the first and second wires are provided with a break point to cut off their respective circuits.

[0008] The isolation seal is provided with a filler electrode to fill in the missing wire at the break point to make the line conductive again.

[0009] Preferably, the self-reactive electrical energy device includes two vertically opposed spacer plates, an electrolytic shell disposed between the two spacer plates, an electrolytic assembly disposed inside the electrolytic shell, and two ends of the electrolytic assembly extending out from the two spacer plates and electrically connected to an alarm device.

[0010] The electrolytic shell has multiple flow holes for the electrolyte solution to flow into the electrolytic shell and react chemically with the electrolytic components. The alarm device does not activate when the electrolytic components are undergoing the first stage of chemical reaction; the alarm device activates when the electrolytic components are undergoing the second stage of chemical reaction to remind the staff to remove the temporary blind flange from the pipeline. The time consumed by the first stage of chemical reaction is greater than the total operation time of the temporary blind flange installation and pipeline tightness test.

[0011] Preferably, the electrolysis assembly includes a first metal substrate, a second metal substrate, and a metal foil.

[0012] The first metal substrate is fixed inside the upper spacer plate. The end of the first metal substrate extends out of the spacer plate and is connected to the wire. The second metal substrate is fixed inside the lower spacer plate. The end of the second metal substrate extends out of the spacer plate and is also connected to the wire. One end of the metal foil is physically connected to the first metal substrate and the other end is physically connected to the second metal substrate. The material of the metal foil is different from that of the first and second metal substrates and is the most reactive.

[0013] Preferably, a graphite conductive strip is further provided at the connection between the metal foil and the first metal substrate and the second metal substrate.

[0014] Preferably, the metal foil also has an adjustment hole penetrating through the foil body at its center, and the adjustment hole is used to adjust the delay start time of the control alarm device.

[0015] Preferably, the electrolysis component can be integrally injection molded.

[0016] Preferably, the alarm device includes an audible and visual alarm and an ambient temperature compensation alarm circuit. The temperature compensation alarm circuit includes a first transistor, a second transistor, a first resistor, and a second resistor. The emitter of the first transistor is connected to one end of the audible and visual alarm, and its base is connected to the collector of the second transistor. The collector of the first transistor is connected to the base of the second transistor. The emitter of the second transistor is connected to a third wire as the negative terminal. The other end of the audible and visual alarm is connected to the connection node of the collector of the first transistor and the base of the second transistor. One end of the first resistor and the second resistor are also connected to the connection node of the collector of the first transistor and the base of the second transistor. The other end of the first resistor is connected to the first wire as the high-temperature positive terminal, and the other end of the second resistor is connected to the second wire as the low-temperature positive terminal.

[0017] Preferably, one isolation seal is provided. When the ambient temperature is high, the isolation seal is attached to the surface of the patch and the missing electrode fills the break point of the first wire.

[0018] When the ambient temperature is low, the isolation seal is attached to the surface of the patch and its filler electrode fills the break point of the second wire.

[0019] Preferably, there are two isolation seals, which are simultaneously attached to the surface of the patch. The filler electrode of one isolation seal fills the break point of the first wire, and the filler electrode of the other isolation seal fills the break point of the second wire. One of the isolation seals is removed according to the ambient temperature, while the other isolation seal is retained.

[0020] Preferably, the first patch and the second patch are adhered and fixed together.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention can spontaneously react chemically with the electrolyte solution and generate current after a specific time to power the alarm device to activate the alarm, thereby achieving the effect of alarm notification after the pipeline tightness test. This reminds the staff to remove the temporary blind flange in time after the pipeline tightness test, so as to avoid the temporary blind flange being left at the pipeline connection point, which would affect the normal use of subsequent pipelines and cause quality accidents. Moreover, no external power supply is required, making it convenient and widely applicable.

[0023] 2. The patch housing of the present invention is made of plastic, which has moisture-proof properties and is suitable for open salt spray environments such as shipyards and marine engineering, with high reliability.

[0024] 3. This invention adds a metal foil between the anode and cathode of the self-reactive power device, so that the metal foil is directly physically connected to the anode and cathode. This enables the alarm to be activated after a period of time, so as to achieve the effect of alarm prompting after the pipeline tightness test is completed. The design concept of this application is ingenious. It cleverly uses the fastening force of the pipeline flange to enable the self-reactive power device to generate current to power the alarm device.

[0025] 4. This invention can be used in challenging working conditions such as cooling water pipelines for main and auxiliary marine engines, pipelines in the deck overhang area, or confined spaces. It has a wide range of applications and is more applicable. It can also be used for temporary closure of pipelines during pipeline tightness testing before sea trials without causing damage to marine equipment.

[0026] 5. This invention incorporates an ambient temperature compensation alarm circuit on the alarm device to compensate for the actual output voltage of the self-reacting power device. This prevents the temperature environment from affecting the electrolyte reaction of the self-reacting power device and thus the activation potential of the audible and visual alarm, effectively ensuring the accuracy of the delayed alarm time of the audible and visual alarm.

[0027] 6. In the ambient temperature compensation alarm circuit of the present invention, the high-temperature positive terminal is connected to the anode of the self-reactive power device through a first wire, the low-temperature positive terminal is connected to the anode of the self-reactive power device through a second wire, and the negative terminal is connected to the cathode of the self-reactive power device through a third wire. Both the first and second wires have break points to cut off their respective circuits. By attaching an isolation seal to the patch and using the fill electrode on the isolation seal to fill the missing wire at the break point on the first or second wire to make the circuit conductive, the actual output voltage of the self-reactive power device is compensated, ensuring the stability of the start-up potential of the audible and visual alarm, and thus ensuring the accuracy of the delayed alarm time of the audible and visual alarm.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0058] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0059] This invention provides an ambient temperature compensation audible and visual alarm patch, comprising a patch 3, a self-reactive power device 1 disposed inside the patch 3, and an alarm device 2. This device is used on marine temporary blind flanges to remind personnel to promptly remove the temporary blind flanges installed between opposing pipelines after the completion of a pipeline tightness test.

[0060] Specifically, the self-reactive power device 1 is used to spontaneously react with the electrolyte solution to generate current, which powers the alarm device 2. The two electrodes of the self-reactive power device 1 are connected to the alarm device 2 via wires. The alarm device 2 will only activate and sound an alarm after the self-reactive power device 1 has reacted with the electrolyte solution for a period of time, achieving a delayed alarm effect. This serves to remind personnel to remove the temporary blind flange in a timely manner after the pipeline tightness test is completed, preventing the temporary blind flange from being left inside the pipeline.

[0061] The self-reactive electrical energy device 1 includes two vertically opposed spacer plates 1.1 and an electrolytic shell 1.2 disposed between the two spacer plates 1.1. An electrolytic assembly is disposed inside the electrolytic shell 1.2. The two ends of the electrolytic assembly extend out of the two spacer plates 1.1 respectively and are connected to an external alarm device 2 via wires. The electrolytic shell 1.2 has multiple flow holes 1.7 for allowing the electrolyte solution to flow into the interior of the electrolytic shell 1.2.

[0062] The electrolysis assembly includes 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 inside the upper spacer plate, and its end extends upwards beyond the spacer plate and is connected to a wire (i.e., the electrode of the first metal substrate 1.3 extends out of the housing of the reactive power device). The second metal substrate 1.4 is fixed inside the lower spacer plate, and its end extends downwards beyond the spacer plate and is also connected to a wire 5 (i.e., the electrode of the second metal substrate 1.4 also extends out of the housing of the reactive power device). The metal foil 1.5 is vertically arranged, with one end directly physically connected to the first metal substrate 1.3 and the other end directly physically connected to the second metal substrate 1.4. The material of the metal foil 1.5 is different from that of the first metal substrate 1.3 and the second metal substrate 1.4, and it is the most reactive. The thickness of the metal foil 1.5 is much smaller than the thickness of the first metal substrate 1.3 and the second metal substrate 1.4.

[0063] Assuming the first metal substrate 1.3 is the anode and the second metal substrate 1.4 is the cathode, the metal foil 1.5 is more reactive than the first metal substrate 1.3, and the first metal substrate 1.3 is more reactive than the second metal substrate 1.4 (for example, the first metal substrate is a zinc plate, the second metal substrate is a copper plate, and the metal foil is magnesium). When the electrolyte solution flows into the electrolytic shell 1.2 through the flow hole 1.7, the metal foil 1.5 first undergoes an oxidation reaction. Since the metal foil 1.5 is in direct physical contact with the first metal substrate 1.3 and the second metal substrate 1.4, an internal short circuit is formed between the first metal substrate 1.3 and the second metal substrate 1.4. The electron flow that should have passed through the external circuit will flow directly from the first metal substrate 1.3 to the second metal substrate 1.4 through the metal foil 1.5. Therefore, the actual output voltage of the self-reaction power device 1 is close to 0, and the alarm device 2 will not be activated and will not sound an alarm. However, 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, accepting these electrons and undergoing a reduction reaction. The actual output voltage of the self-reaction power device 1 becomes the value determined by the standard electrode potential difference between the first metal substrate 1.3 and the second metal substrate 1.4, and the alarm device 2 is activated to sound an alarm.

[0064] Therefore, the self-reactive electrical energy device 1 will carry out two stages of chemical reaction. The first stage of chemical reaction is the consumption of metal foil 1.5, and its consumption time is not less than the total operation time of the marine temporary blind flange installation and pipeline tightness test. The second stage of chemical reaction is the consumption of the first metal substrate 1.3.

[0065] By controlling the consumption time of the metal foil 1.5, the delayed start time of the alarm device 2 can be controlled. For example, by opening an adjustment hole 1.6 through the foil body in the center of the metal foil 1.5, the consumption rate of the metal foil 1.5 can be accelerated, thereby reducing the delayed start time of the alarm device 2.

[0066] Furthermore, the delay start time of the alarm device 2 can be further adjusted by adjusting the diameter of the adjusting hole 1.6. Of course, other methods can also be used to control the delay start time of the alarm device 2.

[0067] The aforementioned electrolysis components can be manufactured as a whole by injection molding. After manufacturing, they are assembled with the spacer plate 1.1 and the electrolysis shell 1.2 to form a self-reactive power device 1, and then encapsulated in the patch. Alternatively, the self-reactive power device can also be manufactured as a whole by injection molding and then encapsulated in the patch body 1, which is made of plastic.

[0068] The alarm device 2 includes an audible and visual alarm 2.1 and an ambient temperature compensation alarm circuit.

[0069] The audible and visual alarm 2.1 is used to provide audible and visual alarms to remind staff to remove the temporary blind flange in a timely manner after the pipeline tightness test is completed, so as to avoid leaving the temporary blind flange in the pipeline.

[0070] Since the pipeline is used in indoor or outdoor environments, with ambient temperatures ranging from 25℃-45℃ (high temperature) to -10℃-25℃ (low temperature), the ambient temperature will affect the electrolytic reaction time, causing fluctuations in the actual output voltage of the self-reacting power device 1. This leads to deviations in the time it takes for the ambient temperature compensation alarm circuit to reach the activation potential of the audible and visual alarm 2.1, which to some extent affects the accuracy of the delayed alarm time of the audible and visual alarm 2.1. The ambient temperature compensation alarm circuit 13 is used to compensate for the actual output voltage of the self-reacting power device to ensure that the activation potential of the audible and visual alarm remains at a stable value (or within a stable range), avoiding the impact of temperature on the electrolyte reaction of the self-reacting power device, which would affect the activation potential of the audible and visual alarm and thus the accuracy of the delayed alarm time.

[0071] The ambient temperature compensation alarm circuit 13 includes a first transistor 2.3, a second transistor 2.4, a first resistor 2.2, and a second resistor 2.5. The emitter of the first transistor 2.3 is connected to one end of the audible and visual alarm 2.1, and its base is connected to the collector of the second transistor 2.4. The collector of the first transistor 2.3 is connected to the base of the second transistor 2.4. The other end of the audible and visual alarm 2.1 is connected to the junction of the collector of the first transistor 2.3 and the base of the second transistor 2.4. One end of the first resistor 2.2 and the second resistor 2.5 are also connected to the junction of the collector of the first transistor 2.3 and the base of the second transistor 2.4. The resistance of the first resistor 2.2 is greater than the resistance of the second resistor 2.5. In this embodiment, the first transistor 2.3 is a PNP transistor, and the second transistor 2.4 is an NPN transistor.

[0072] The other end of the first resistor 2.2 serves as the high-temperature positive terminal of the ambient temperature compensation alarm circuit 13 and is connected to the first wire 9. The other end of the second resistor 2.5 serves as the low-temperature positive terminal of the ambient temperature compensation alarm circuit 13 and is connected to the second wire 10. The emitter of the second transistor 2.4 serves as the negative terminal of the ambient temperature compensation alarm circuit 13 and is connected to the third wire 11. The anode of the self-reacting power device 1 is also connected to the first wire 9 and the second wire 10, and the cathode is connected to the third wire 11. However, both the first wire 9 and the second wire 10 are provided with a break point 5 to disconnect their respective circuits.

[0073] When the ambient temperature is high, the missing wire at the break point 5 on the first conductor 9 can be filled by the filler electrode 6 on the isolation seal 12 to make the line conductive; when the ambient temperature is low, the missing wire at the break point 5 on the second conductor 10 can be filled by the filler electrode 6 on the isolation seal 12 to make the line conductive.

[0074] In one embodiment, before attaching the ambient temperature compensation audible and visual alarm patch described in this application to the marine temporary blind plate, an isolation seal 12 can be attached to a suitable position on the patch 3 according to the ambient temperature to ensure that the first wire 9 or the second wire 10 is conductive.

[0075] In another embodiment, before attaching the ambient temperature compensation audible and visual alarm patch described in this application to the marine temporary blind plate, two isolation strips 12 can be attached to the patch 3. One isolation strip 12 has a filler electrode 6 that fills the break point of the first wire 9, and the other isolation strip 12 has a filler electrode 6 that fills the break point of the second wire 10. Figure 6 As shown. After attaching the ambient temperature compensation audible and visual alarm patch to the ship's temporary blind flange, one of the isolation seals can be removed according to the ambient temperature. For example, if the ambient temperature is within the range of 25℃-45℃, the isolation seal on the left side should be removed. Figure 7As shown; if the ambient temperature is within the range of -10℃ to 25℃, tear off the isolation seal on the right side, as shown. Figure 8 As shown.

[0076] The isolation seal 12 can be made of plastic, and the defect-compensating electrode 6 on it can be made of aluminum foil to provide temporary conductivity.

[0077] In this embodiment, the isolation seal 12 is semi-circular, with its waist-shaped end placed outside the patch so that staff can quickly tear off the isolation seal.

[0078] In actual use, the ambient temperature compensation audible and visual alarm patch of the present invention is pasted and fixed on the temporary blind flange. When the marine temporary blind flange is installed between two opposite pipe flanges, during the tightening of the flange bolts, the electrolyte solution can be introduced into the self-reacting electrical energy device 1 to carry out a chemical reaction in a specific way, and the alarm device 2 will sound an alarm after a specific time to prompt the removal of the marine temporary blind flange. The length of the specific time is longer than the total operation time of the marine temporary blind flange installation and the pipeline tightness test.

[0079] The manner in which the electrolyte solution enters the self-reacting electrical energy device 1 is not the subject of this application, but it can be achieved in some way, for example... Figure 1 As shown, an electrolyte solution 8 can be encapsulated within a hollow blind flange patch 7. The blind flange patch 7 is fixed as a single unit or manufactured as a single unit with the first patch 3 of this application. The blind flange patch 7 is then attached to the temporary blind flange 14. When the temporary blind flange 14 is installed between two opposing pipeline flanges, during the tightening of the flange bolts, the electrolyte solution inside the blind flange patch will break through the encapsulation film and enter the self-reacting electrical energy device 1 under the action of extrusion force, where a chemical reaction will occur. An alarm will be triggered after a specific time to prompt the removal of the marine temporary blind flange. The duration of the specific time is longer than the total operation time of the marine temporary blind flange installation and pipeline tightness test.

[0080] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
