Description

Technology Field

[0001] The present invention relates to a water meter freeze prevention device using a battery, and more specifically, to a water meter freeze prevention device using an improved battery that incorporates a replaceable battery in a rechargeable state and effectively prevents the water meter from freezing in severe cold weather through the heat generated by a heating lamp via the battery. Background Technology

[0002] Generally, a water meter (also called a 'water pump box') is designed to allow the external measurement of water usage in individual buildings or households.

[0003] For example, in the case of multi-unit buildings or structures including apartment buildings, they are usually installed embedded in the interior walls, while in the case of single-family houses used for livestock, agriculture, factories, or rural areas, they are installed embedded in part of the ground and completely exposed to the air.

[0004] Therefore, if the outside temperature drops sharply during the cold season, there is a risk that the water meter will freeze.

[0005] In particular, in the case of multi-unit dwellings, separate thermal insulation is sometimes installed around the water meter, but even this insulation cannot prevent the meter from freezing if the outside temperature is very low.

[0006] For example, Korean published patent No. 10-2017-0101836 provides "a water meter freeze prevention sheet for covering the door of a water meter box installed on a wall, comprising: a first film member made of a thin film-shaped synthetic resin film; a second film member made of a thin film-shaped synthetic resin film having the same area as the first film member; an insulating layer interposed between the first film member and the second film member and mutually bonded to form an integral with the first film member and the second film member; and a fixing means provided on the outer edge of the first film member and attached to the wall." However, the problem of freezing of the meter often arises at extremely low temperatures during the severe cold season. Prior art literature

[0008] The present invention was created to solve the various problems of the prior art as described above, and provides a water meter freeze prevention device using an improved battery that incorporates a replaceable battery in a rechargeable state and effectively prevents the water meter from freezing in the cold weather through the heat generated by a heating lamp via the battery. means of solving the problem

[0009] The objective of the present invention can be achieved by providing a water meter freeze prevention device using a battery, comprising: a main body with an open top; a cover that seals the open top of the main body and has a battery holder installed on its rear side; a battery accommodated in the battery holder of the cover; a controller installed on the rear side of the cover and driven by receiving power from the battery; a temperature sensor installed on the surface of the cover that detects the temperature in the air and outputs it to the controller; and a plurality of heating lamps installed on the rear side of the cover that operate on and off according to a control signal from the controller; wherein a water meter is built inside the main body and water pipes are connected to both ends of the water meter. Effects of the invention

[0010] According to the present invention, there is an effect of effectively preventing the freezing of a water meter in severe cold weather by incorporating a rechargeable and replaceable battery and generating heat from a heating lamp through this battery. Brief explanation of the drawing

[0011] FIG. 1 is an exemplary cross-sectional view of a water meter freeze prevention device using a battery according to the present invention. Specific details for implementing the invention

[0012] Hereinafter, a water meter freeze prevention device using a battery according to the present invention will be described in more detail.

[0013] Figure 1 attached is an exemplary cross-sectional view of a water meter freeze prevention device using a battery according to the present invention.

[0014] Referring to the above drawing, it applies to the part of the indoor wall of a multi-unit dwelling, such as an apartment, where a water meter is installed.

[0015] The anti-freezing device for a manual meter according to the present invention includes a main body (100) which is a housing. The main body (100) is installed on an indoor wall of a multi-unit dwelling and is sealed by a cover (110).

[0016] And, a battery holder (111) is installed on the back side of the cover (110), and a battery (120) is inserted into the battery holder (111). Specifically, the battery holder (111) is formed in a shape that protrudes from the back side of the cover, with the end bent inward, so that a battery can be accommodated inside the battery holder, and it is obvious that various shapes capable of accommodating a battery can be adopted, not limited to this formation.

[0017] In addition, the battery is received in the battery holder while in a charged state, and when discharged, the battery can be removed from the battery holder and recharged for continuous use. In particular, since the present invention is applicable only during the cold season, the inconvenience can be reduced by charging and receiving the battery in the holder before winter arrives.

[0018] Meanwhile, although not shown, a controller (not shown) that is powered by receiving power from the battery (120) is mounted on the back side of the cover (110), and a temperature sensor is embedded in a part of the surface of the cover (110), and is electrically connected to output temperature information detected by the temperature sensor to the controller.

[0019] In addition, a plurality of heating lamps (130) are installed on the back side of the cover (110), and the heating lamps (130) are configured to be electrically connected to the controller to be controlled on / off. Here, the heating lamps are preferably LED lamps.

[0020] In addition, a water meter (C) is built inside the main body (100), and water pipes (P) are connected to both ends of the water meter (C).

[0021] Accordingly, when the ambient temperature in winter drops below freezing, preferably below 0℃, the controller confirms this through the temperature sensor and activates the heating lamp (130).

[0022] Then, the internal space of the main body (100) sealed by the cover (110) is heated by the heat emitted by the heating lamp (130), and affects the water pipe (P) installed inside the main body (100) so that the water flowing through the water pipe (P) does not freeze, thereby preventing the water pipe from freezing.

[0023] In this case, a coating layer (140) coated with a thermally conductive coating agent is further formed on the outer surface of the water pipe (P) embedded in the main body (100) so that the heat emitted by the heating lamp (130) is well absorbed and conducted into the water pipe (P), thereby further increasing the anti-freezing effect.

[0024] The thermally conductive coating agent for this purpose comprises 10 wt% chloroacetic acid, 15 wt% graphite, 30 wt% paraffin wax, and n-hexadecane (C 16 H 34 It consists of 10% by weight and the remainder being epoxy resin.

[0025] In this case, chloroacetic acid has a large latent heat capacity, which increases heat absorption and affects the insulation of water pipes.

[0026] In addition, graphite increases thermal conductivity, contributing to heat retention by fully transferring the heat emitted from the heating lamp to the water pipe.

[0027] Furthermore, paraffin wax is a representative heat-storing phase change material that contributes to enhancing heat retention and retention capabilities.

[0028] In addition, hexadecane (n-Hexadecane, C 16 H 34 ) is a phase change material that contributes to suppressing the temperature drop on the surface of water pipes due to latent heat when the temperature drops below freezing, thereby preventing freezing.

[0029] Furthermore, epoxy resin is a base resin with excellent heat absorption and thermal retention properties.

[0030] In addition, the above paraffin wax is not added alone, but is characterized by using a mixture of paraffin wax and 6-bromohexanoic acid in a weight ratio of 7:3.

[0031] In this case, 6-bromohexanoic acid prevents the penetration of oxygen moisture, thereby preventing cracks and fractures in the coating layer, preventing deterioration, and not only increases water resistance but also increases adhesion to induce a long lifespan.

[0032] Meanwhile, in the present invention, when composing the thermally conductive coating agent, 10 parts by weight of zinc hexahydrate (Zn(NO3)2·6H2O), 4.5 parts by weight of hexafluoropropylene, 10 parts by weight of alkylbenzene sulfonate, and 5.5 parts by weight of 5-isopropyl-3-methylphenol may be further added to 100 parts by weight of the epoxy resin.

[0033] In this case, zinc nitrate hexahydrate (Zn(NO3)2ㆍ6H2O) contributes to preventing water pipes from freezing by increasing heat retention capacity through the formation of a eutectic point.

[0034] In addition, hexafluoropropylene maintains curing stability and simultaneously secures flexural strength, and contributes to securing fixation stability by suppressing interfacial separation of the coating layer.

[0035] In addition, alkylbenzene sulfonate is a substance corresponding to CAS number 25155-30-0, and as an anionic surfactant, it has the characteristic of being able to withstand hard water, and in particular, contributes to strengthening salt resistance and freeze-thaw resistance.
