Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meters, in particular to an antifreeze intelligent water meter. Background Art

[0002] A water meter is an instrument that measures water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. When a water meter is used in cold temperatures, the water inside the meter is prone to freezing inside the meter, affecting the use of the water meter. Currently, in order to prevent freezing inside the water meter, a circulation pipe and an insulating shell are usually installed inside the water meter. When the water meter is not in use, the internal water circulates to prevent the water from freezing. At the same time, the insulating shell reduces heat loss in the water meter.

[0003] In -3℃ weather, water circulation is usually used to prevent the water inside the water meter from freezing. The water circulation inside the water meter is usually slow, but in extremely cold weather, the water with a slow flow rate inside the circulation pipe is easy to freeze into ice chips, which is prone to ice chip obstruction. This method of using only water circulation cannot effectively prevent freezing inside the water meter.

[0004] In response to the above technical problems, the present application proposes an anti-freeze smart water meter. Utility Model Content

[0005] 1. Technical Problems Solved

[0006] The technical problem to be solved by the utility model is that in extremely cold weather, water with a relatively slow flow rate inside the circulation pipe is easily frozen into ice chips, which easily leads to ice chip obstruction.

[0009] The heating assembly includes an L-shaped cover body, the inside of the L-shaped cover body is provided with a slot for fitting a circulation pipe, the internal cavity structure of the L-shaped cover body is installed with multiple groups of heating rods, the outside of the L-shaped cover body is installed with a protector connected to the multiple groups of heating rods, the outside of the first heat-insulating shell body is installed with a controller connected to the protector and the pump body, and the side wall of the L-shaped cover body is connected to a water inlet pipe.

[0010] As an improvement, a mounting block is installed at the bottom of the L-shaped cover, and the mounting block is connected to the first heat-insulating shell through multiple groups of bolts.

[0011] As an improvement, a through hole is provided on the side wall of the first heat-insulating shell for the water inlet pipe to pass through, and the other end of the water inlet pipe slides out of the through hole and is installed with a sealing cover.

[0012] As an improvement, the L-shaped cover and the circulation pipe are both made of heat-conducting metal, and the circulation pipe is in contact with the slot on the inner side of the L-shaped cover.

[0013] As an improvement, connecting strips are respectively installed on the opposite side walls of the first heat-insulating shell and the second heat-insulating shell, and multiple groups of bolts 2 pass through the two opposite groups of the connecting strips, and nuts are installed on the outside of the bolts 2.

[0014] As an improvement, a second controller is installed on the outer wall of the first heat-insulating shell, and the second controller is electrically connected to the water meter body.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] As attached Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, an antifreeze smart water meter includes a water meter body 1, with water pipes 2 connected to both ends of the water meter body 1, a circulation pipe 4 installed on the water pipe 2, and a pump body 5 connected between the two sets of circulation pipes 4. A first insulation shell 6 and a second insulation shell 7 are installed on the outside of the water meter body 1, and a second controller 16 is installed on the outer wall of the first insulation shell 6. The second controller 16 is electrically connected to the water meter body 1;

[0027] The other end of the water pipe 2 passes through the first heat-insulating shell 6 and is connected to the second heat-insulating shell 7, and is connected to the connecting sleeve 3, and is sealed and connected to the external water pipe through the connecting sleeve 3;

[0028] The first thermal insulation shell 6 and the second thermal insulation shell 7 are respectively installed with connecting strips 18 on the opposite side walls. A plurality of groups of bolts 19 are passed between the two opposite groups of connecting strips 18. Nuts are installed on the outside of the bolts 19. After the first thermal insulation shell 6 and the second thermal insulation shell 7 are installed on the outside of the water meter body 1, the bolts 19 are passed through the two opposite groups of connecting strips 18, and the nuts are put on the outside of the bolts 19 to connect the first thermal insulation shell 6 and the second thermal insulation shell 7.

[0029] Through the above structure, the external water pipe sends water to the water pipe 2, the water is sent to the water meter body 1 through the water pipe 2, and the water is discharged through another set of water pipes 2, so that the water meter body 1 can measure the cumulative flow of water.

[0030] As attached Figure 1 , Attachment Figure 2 and attached Figure 3As shown, a heating component that cooperates with the circulation pipe 4 is installed inside the first heat-insulating shell 6. The heating component includes an L-shaped cover 8. The inner side of the L-shaped cover 8 is provided with a card slot for the circulation pipe 4 to be inserted. The internal cavity structure of the L-shaped cover 8 is installed with multiple groups of heating rods 9. A protector 10 connected to the multiple groups of heating rods 9 is installed on the outside of the L-shaped cover 8. When the heating rods 9 are short-circuited or the temperature is high, the power is cut off to prevent damage and leakage of the multiple groups of heating rods 9. A controller 17 connected to the protector 10 and the pump body 5 is installed on the outside of the first heat-insulating shell 6.

[0031] The L-shaped cover 8 and the circulation pipe 4 are both made of heat-conducting metal. The circulation pipe 4 contacts the slot inside the L-shaped cover 8 to ensure good thermal conductivity between the L-shaped cover 8 and the circulation pipe 4.

[0032] Through the above structure, the controller 2 16 is connected to the controller 1 17. When the water meter body 1 is measuring water flow, the controller 2 16 transmits information to the controller 1 17, and the controller 1 17 stops the pump body 5 and the heating component. When the water meter body 1 is not measuring water flow, the pump body 5 and the heating component are operated again.

[0033] The pump body 5 is started by the controller 17, and the water at both ends of the water meter body 1 is circulated through the pump body 5 and the two groups of circulation pipes 4. The heating rods 9 are started by the controller 17, so that the multiple groups of heating rods 9 are heated, and the water inside the L-shaped cover 8 is heated by the heating rods 9. The heat is absorbed by the L-shaped cover 8 and transferred to the circulation pipe 4 to achieve heating of the water inside the circulation pipe 4. The L-shaped cover 8 dissipates part of the heat to the inside of the first insulation shell 6 and the second insulation shell 7. The temperature loss can be reduced through the first insulation shell 6 and the second insulation shell 7, so that the temperature difference between the inside and outside of the circulation pipe 4 is small, thereby preventing the circulation pipe 4 from breaking.

[0034] Combined with attachment Figure 2 and attached Figure 6 As shown, the side wall of the L-shaped cover 8 is connected to a water inlet pipe 13, and the side wall of the first heat-insulating shell 6 is provided with a through hole 15 for the water inlet pipe 13 to pass through. The other end of the water inlet pipe 13 slides out of the through hole 15 and is installed with a sealing cover 14.

[0035] Through the above structure, water is delivered to the interior of the L-shaped cover 8 through the water inlet pipe 13 , and after the water delivery is completed, the end of the water inlet pipe 13 is sealed by the sealing cover 14 .

[0036] Combined with attachment Figure 1 and attached Figure 2 As shown, a mounting block 11 is installed at the bottom of the L-shaped cover 8, and the mounting block 11 is connected to the first heat-insulating shell 6 through multiple groups of bolts 12.

[0037] Through the above structure, multiple groups of bolts 12 pass through the mounting block 11 and are installed to the inner wall of the first heat-insulating shell 6 , stably installing the L-shaped cover 8 inside the first heat-insulating shell 6 .
