Description

Load Activated Reserve Battery and Leakage Detecting System Including Thereof

The present invention relates to a load-activated storage battery and a leak detection system including the same, and more particularly, to a load-activated storage battery for detecting water leakage in a pipe such as a water supply, and a leak detection system including the same.

As the demand for water increases due to an increase in population and urbanization, water supply pipes are continuously increasing and becoming more complicated in order to supply water smoothly and stably. In addition, the efficiency of supply is lowered due to water leakage in old pipes, and when leakage of pipes occurs, secondary damage due to water leakage occurs in the vicinity of the leakage point.

In order to efficiently detect the occurrence of such a leak and take action, a highly reliable leak detection system is essential. Most of the existing water leak detection in water supply pipelines is a sensor method that uses electricity, and technologies such as photographing the inside of the pipe by mounting a camera, detecting leaks using water pressure difference, or detecting using resistance measurement were used. Improvement is required in terms of the problem of continuously supplying power and expensive replacement costs due to periodic replacement of the battery when using the battery. Accordingly, there is a need for a technology capable of solving the problem of occurrence of replacement cost due to battery replacement and maintaining stable monitoring.

A portion of the pipe 1 surrounded by the water leak collecting part 100 is sealed or covered from the outside. When a water leak occurs in a portion of the pipe 1 surrounding the water leakage collecting unit 100 , the water leaks downward along the inner surface of the water leakage collecting unit 100 .

Since the lower end portion 110 of the water leakage collecting unit 100 has a shape facing the inside of the water storage port 300, for example, a shape inclined toward the inside, it flows along the inner surface of the water leakage collecting unit 100. The falling water is collected inside the water storage port 300 and stored in the water storage space 310 of the water storage port 300 .

The water leak collecting part 100 may be made of a material such as stainless steel having corrosion resistance so as not to be corroded by water or moisture.

Since the water storage port 300 also stores water leakage, it may be made of a material having corrosion resistance to prevent rust from occurring.

When the water leak is stored in the water storage space 310 and the leak continues from the pipe 1 , the load of the water storage port 300 in which the leak is stored increases. When the load of the water storage port 300 in which the leak is stored increases and exceeds the reference value, the water storage port 300 moves downward.

In addition, the water storage port 300 is supported by the support 330 . The support part 330 allows the downward movement of the water storage port 300 when the load of the water storage port 300 in which the leak is stored is greater than or equal to the reference value. That is, when the load of the water storage port 300 in which the leak is stored is less than the reference value, the downward movement of the water storage port 300 is restricted by the support part 330 .

The support part 330 is damaged or compressed when a load greater than or equal to the reference value is applied, and at this time, it is preferable that the water storage port 300 in which the water leaks are stored moves downward.

Two or more layer 331 structures are formed as in an inactive state in the breakage type support 330 as shown in FIG. A form in which the support 333 is formed so that it can be damaged when it exceeds the reference value is possible.

In this case, the starting point of failure at which the support 333 begins to be destroyed without bearing the load, that is, the reference value may be set using the number of supports 333 and the thickness of the support 333 as variables. When the load of the water storage port 300 in which the leak is stored becomes a load greater than the reference value, which is the starting point of destruction, and the support 333 is damaged, the height of the support 330 is lowered as shown in FIG. 300) and the breaking needle 350, which is the starting part 350, moves downward. In this way, the support part 330 of the breakage method is also possible.

In Fig. 5(a), the spring 330' is shown as an exemplary form, and the form of the spring 330' is schematically shown in an inactive state, that is, in a state less than a reference value.

When the support part 330' is formed using a spring 330' compressed by a load or an elastic body, the water storage port 300 and the start part 350 are moved downward while being compressed according to the load of the leak to be detected. The elastic modulus may be set to damage the electrolyte accommodating part 400 . Therefore, when the load of the water storage port in which the leak is stored is the reference value or exceeds the reference value, the support part 330' such as the spring 330' is compressed as shown in FIG. ) is activated.

In addition, a protection unit 210 is disposed between the water leakage collecting unit 100 and the case 200 to protect the water storage port 300 from the outside and surrounding the outside of the water storage port 300 . The upper end of the protection unit 210 is coupled to the water leakage collecting unit 100 , and the lower end of the protection unit 210 is coupled to the upper end of the case 200 , so the water storage port 300 and the support unit 330 are external. can be protected from

Since the protection unit 210 is positioned between the water leakage collecting unit 100 and the case 200 to cover and protect the water storage port 300 from the outside, the water storage port 300 is not affected by the outside. The support part 330 and the start part 350 are also protected from the outside by the protection part 210 like the water storage port 300 .

As mentioned above, a hole 235 is provided so that the breaking needle 350, which is the starting part 350, can move into the case 200, and the electrolyte housing 430 has the breaking needle ( It is preferable that a through-hole 435 is provided so that the 350) enters the inside of the electrolyte housing 430 to damage the electrolyte accommodating part 400 .

In addition, the electrolyte accommodating part 400 is preferably made of a flexible material so that the electrolyte 410 is contracted when the electrolyte accommodating part 400 is damaged by the initiating part 350 . Of course, it is sufficiently possible that the electrolyte accommodating part 400 is made in the form of an ampoule made of a material such as glass that can be broken by the initiating part 350 .

When the electrolyte accommodating part 400 is contracted, the electrolyte 410 in the electrolyte accommodating part 400 is easily discharged, so the amount of the electrolyte 410 remaining in the electrolyte accommodating part 400 is reduced and a sufficient amount The electrolyte 410 is discharged into the inner space of the electrolyte housing 430 and can be moved to the unit cell 500 .

This unit cell 500 is activated when the electrolyte 410 flows in from the electrolyte solution side. In the inactive state, the electrolyte 410 is not introduced into the unit cell 500, and while maintaining this inactive state, the electrolyte 410 is introduced and activated as described above due to leakage. The positive electrode material 510 and the negative electrode material 530 have first and second surfaces facing each other with the separator 520 interposed therebetween, and in an activated state, the electrolyte 410 forms the separator 520 with each other. Accordingly, it is distributed between the positive electrode material 510 and the negative electrode material 530 to generate a current.

The sealing material 540 prevents the electrolyte 410 from leaking unintentionally from the side of the unit cell 500 . As the sealing material 540, a gasket or a rubber O-ring may be used. The unit cell 500 may be provided in the form of a battery or a supercapacitor.

An electrolyte inlet hole (not shown) is formed in the unit cell 500 so that the electrolyte 410 can be introduced therein. The electrolyte 410 discharged from the electrolyte receiving unit 400 and flowing into the unit cell 500 flows around the separator 520 interposed between the positive electrode material 510 and the negative electrode material 530 and flows into the unit. Cell 500 is activated.

That is, since there is no electrolyte 410 between the positive electrode material 510 and the negative electrode material 530 in normal times, power is not generated in an inactive state.

When the electrolyte 410 is introduced between the positive electrode material 510 and the negative electrode material 530 , power is generated in an activated state. The electrolyte 410 flowing into the unit cell 500 is interposed between the positive electrode material 510 and the negative electrode material 530 . Accordingly, the electrolyte 410 may act as a medium through which ions may move between the positive electrode material 510 and the negative electrode material 530 .

The anode material 530 emits electrons while an oxidation reaction occurs, and the emitted electrons reduce positive ions in the electrolyte 410 . The reduced cations may become neutrons, and the neutrons move to the positive electrode material 510 and are reduced while providing electrons to the positive electrode material 510 . Since the flow of electrons may occur due to the oxidation-reduction reaction in the cathode material 510 and the anode material 530 , a current may be generated.

The cathode material 510 may be formed using, for example, a ceramic material based on alkali metal, alkaline earth metal, transition metal, or post-transition metal in the case of a battery. In the case of supercapacitors, activated carbon powder, activated carbon fibers, carbon-based materials such as carbon airgel, metal oxides, conductive polymer materials, and the like are included.

The negative electrode material may be formed by including a carbon-based material, an alkali metal, an alkaline earth metal, a transition metal, a metal-based ceramic material after the transition, lithium, silicon, and the like. In the case of supercapacitors, activated carbon powder, activated carbon fibers, carbon-based materials such as carbon airgel, metal oxides, conductive polymer materials, and the like are included.

The electrolyte material may include an alkali metal, an alkaline earth metal-based material, or the like in the case of a battery. In addition, in the case of supercapacitors, acids, bases, and materials in all pH ranges may be included. The electrolyte solution may be used as common solvents used in commercial batteries.

In addition, a multi-layered structure of the unit cells 500 may be formed by electrically connecting the unit cells 500 according to the required capacitance or voltage. Accordingly, a form in which a plurality of the unit cells 500 are stacked is also sufficiently possible.

A flow path plate 560 may be provided for uniform supply of electrolyte 410 and electrical connection between each unit cell. Whether to apply the flow path plate 560 may be determined as necessary according to the shape of the battery, the structure of the stack, the active area, and the like.

Accordingly, in order to supply the electrolyte 410 between the plurality of unit cells 500, the passage plate 560 in which the passage through which the electrolyte 410 discharged through the electrolyte communication hole 445 moves is formed is the electrolyte housing ( 430) and the unit cell 500 or between the unit cells 500 adjacent to each other.

The flow path plate 560 may selectively contact one outer surface of the positive electrode material 510 or the negative electrode material 530 . And on one surface, the electrolyte 410 flowing in from the electrolyte housing 430 may be evenly spread. Accordingly, it can be prevented that the electrolyte 410 is partially introduced into the unit cell 500 from not exhibiting the expected performance.

The flow path plate 560 has electrical conductivity and may electrically connect the unit cells 500 forming multiple stages.

A structure in which the unit cells 500 and the channel plates 560 are alternately stacked is also sufficiently possible.

In the structure in which the unit cell 500 and the flow path plate 560 are alternately stacked, the unit cell 500 and the next unit cell adjacent to the unit cell 500 can be electrically connected to the next unit cell 500 adjacent to the unit cell 500 ( 500) may be alternately stacked, and may be connected in series or in parallel, and may form a stack cell in which multi-stage unit cells 500 are stacked. capacity can be increased.

For the material of the flow path plate 560, for example, conductive materials such as metal graphite may be used, and a method of coating a film capable of exhibiting electrical conductivity on a conductive or non-conductive base material may be used, but the present invention is not limited thereto. It is sufficient if it can show conductivity.

As described above, various types and shapes of the battery under the electrolyte accommodating part 400 are possible. The electrolyte housing 430 and the unit cell 500 are protected by the case 200 as described above.

As long as such a unit cell 500 does not leak, it can be protected by being blocked from the external environment by the case 200, and since it can maintain an inactive state, it can be stored for a long time.

In addition, since the electrolyte 410 is uniformly diffused on the surface of the negative electrode material 530 or the positive electrode material 510 through the flow path plate 560 to prevent the unit cell 500 from being partially activated, stable operation can improve the reliability of

A process in which the load-activated reserve battery is activated according to an embodiment of the present invention will be described with further reference to FIGS. 6 and 7 .

As shown in FIG. 6( a ), in normal times when water leakage does not occur in the pipe 1 , the electrolyte accommodating part 400 disposed in the electrolyte housing 430 maintains the state in which the electrolyte 410 is accommodated.

When a water leak occurs in the pipe 1 , the water leak flows down along the inner surface of the water leak collecting unit 100 . At this time, since the lower end portion of the water leakage collecting unit 100 is inclined toward the inner water storage space 310 of the water storage port 300 , water is collected while being collected by the water storage port 300 . In the water storage port 300 in which the water leakage (W) is stored, the load of the water storage port 300 in which the water leakage (W) is stored increases as the amount of the water leakage (W) stored increases.

When the load of the water storage port 300 in which the water leakage W is stored is greater than or equal to the reference value, as described above, the water storage port 300 and the breaking needle 350 move downward while the support 330 is compressed or damaged as described above. The breaking needle 350 breaks the electrolyte accommodating part 400 while passing through the through hole 435 of the electrolyte housing 430. The electrolyte accommodating part 400 damaged by the breaking needle 350 is contracted, As referenced in Figure 6 (b), as the electrolyte accommodating part 400 is contracted, the received electrolyte 410 is discharged into the inner space of the electrolyte housing 430. Discharged into the inner space of the electrolyte housing 430 The electrolyte solution 410 moves toward the lower unit cell 500 through the electrolyte communication hole 445 of the electrolyte housing 430 .

At this time, the damaged and contracted electrolyte accommodating part 400 is fixed in position by the fixing part 450 of the electrolyte housing 430 as shown in FIG. 6(b).

And, as described above, the electrolyte 410 is introduced into the unit cell 500 to generate a current in the unit cell 500 is activated.

When the electrolyte 410 is in the unit cell 500, the content itself of generating a current is well known, and since it has been mentioned above, a repetitive description will be omitted.

For reference, a form in which a cushioning material (not shown) is provided in the load-activated storage battery 10 described above is also possible. The cushioning material may be disposed between the water storage port 300 and the upper surface of the case 200 in order to alleviate the impact caused by the water storage port 300 moving downward, and the arrangement or support portion 330 for supporting the support portion 330 . ) is also possible.

Such a cushioning material may be provided to prevent an excessive impact from being applied to the case 200 when the water storage port 300 rapidly moves downward by its own load. And it is preferable that the cushioning material suppresses excessive shock from being transmitted to the case 200 , but can alleviate the downward movement of the water storage port 300 so that the electrolyte accommodating part 400 can be damaged by the breaking needle 350 .

8 is a block diagram schematically showing a water leak detection system according to an embodiment of the present invention.

Referring to FIG. 8 , the leak detection system according to an embodiment of the present invention includes: a load-activated storage battery 10 according to an embodiment of the present invention; It includes a signal generating unit 20 for generating a signal by the power generated by the load-activated storage battery 10 and a signal transmitting unit 30 for transmitting the generated signal to the outside.

Here, a plurality of load-activated storage batteries 10 may be spaced apart from each other with respect to one pipe 1 . The load-activated storage battery 10 may be attached to a pipe or pipe 1 for supplying or draining water or may be buried in the periphery of the pipe 1, and when leakage occurs due to corrosion or coupling of the pipe 1, , it can be activated by the generated leak.

The signal generating unit 20 is powered by electricity generated from the activated load-activated storage battery 10 to generate a water leak notification signal, and transmits the generated water leak notification signal to the signal transmission unit 30 . can transmit

The signal transmission unit 30 receives power from the load-activated storage battery 10, receives the leak notification signal from the signal transmission unit 30, and sends it to an external, for example, a monitoring device or a management server. The leak notification signal may be transmitted.

In the leak detection system according to an embodiment of the present invention, when a leak occurs in the pipe 1, the load-activated storage battery 10 is activated as described above. As such, as the load-activated storage battery 10 is activated, current may be generated from the load-activated storage battery 10, and the sensor function to detect water leakage and the function to supply power are integrated through the load-activated storage battery 10. Therefore, it is possible to maximize both the efficiency of power use and the reliability of the sensor.

In addition, since the load-activated storage battery 10 is provided as a storage battery capable of long-term storage, continuous supply of power or replacement of the battery may be unnecessary, and the cost required for supply and maintenance of power may be reduced.

On the other hand, since the water leak detection system uses the highly reliable load-activated storage battery 10 according to the present invention, it is possible to prevent malfunction, and it is possible to stably use the water leak detection sensor that can be exposed to the external environment for a long time, It is possible to provide a highly reliable leak detection system.

As such, the load-activated storage battery according to the present invention can store the load-activated storage battery 10 in a standby state for a long period of time, the unit cells can be stacked in multiple stages, and the electric capacity of the load-activated storage battery 10 can be increased. In addition, by inserting a flow path plate between the stacked unit cells, the electrolyte can be uniformly supplied to a plurality of unit cells, and by providing a flow path plate capable of exhibiting electrical conductivity, the electrical connection between the unit cells can be maintained. Therefore, by providing the leak detection system with a load-activated storage battery 10 that can be stored for a long time in a standby state, it is possible to provide a leak detection system in which a power supply and a sensor are integrated, and high reliability that can be used without additional power supply or replacement of leak detection system.

As described above, according to the load-activated storage battery and the leak detection system including the same according to the embodiment of the present invention, since periodic replacement of the battery is not required, the construction cost and maintenance and management cost of the leak detection system can be reduced. . In particular, in the case of a pipe buried in the ground, it takes a lot of money and effort just to replace the battery, but the load-activated storage battery according to the present invention does not require periodic replacement management like a battery, so the maintenance cost of the leak detection system is reduced. It has the advantage of being significantly reduced.

In addition, the load-activated reserve battery according to the present invention has an advantage in that the failure rate due to self-discharge of the battery is suppressed because it does not constantly generate current. In addition, it generates power by itself only when a leak occurs, and since it can transmit a leak detection signal, it has the advantage of improving both the efficiency of power use and the reliability of the sensor, and the load activation ratio according to the present invention. Since the storage battery has excellent long-term storage characteristics, it has the advantage that it is possible to implement a reliable leak detection operation when a leak occurs in an actual pipe.

In addition, since there is no limitation in the selection of the electrolyte material, it is possible to use various organic electrolytes and aqueous electrolytes. Therefore, since it is possible to improve the output and energy density of the battery, there is also an advantage that helps to improve the output energy efficiency.
