Description

Technical Field

[0001] This utility model relates to the field of water flow metering technology, specifically a remote water meter with antifreeze function. Background Technology

[0002] Remote water meters are intelligent metering devices that are an upgrade from traditional mechanical water meters. They can automatically collect water consumption data and transmit it remotely to the water management platform via wireless network, enabling automatic meter reading, big data analysis, online billing, and abnormal water consumption monitoring. They are the core infrastructure for smart water management.

[0003] The existing heating and antifreeze methods for remote water meters mostly involve adding a heating element to the outside of the water meter body, forming a closed space with an insulation structure. Electrical energy is converted into heat energy to maintain the internal temperature of the water meter and prevent the water from freezing. The heating element is usually connected to an external mains power or an internal power supply to generate heat continuously or intermittently. The insulation layer reduces heat loss, thereby ensuring that the water meter's metering components operate normally and the data transmission function is not affected in low-temperature environments. However, remote water meters with only heating function have a single antifreeze method and rely too much on the heating system. When the heating element fails or the power supply is interrupted, the water meter is easily damaged by freezing due to low temperature, affecting its function. Continuous heating has high energy consumption costs, and the antifreeze reliability is insufficient in extremely cold environments. Moreover, its heating effect is easily affected by the environment, heat loss is fast, long-term high temperature will accelerate the aging of the components, improper temperature control may cause thermal damage, and maintenance costs are high. Overall, its practicality, stability and economy are poor. Utility Model Content

[0004] The purpose of this utility model is to provide a remote water meter with antifreeze function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A remote water meter with antifreeze function includes a water meter body, a dial is fixedly installed on the top of the water meter body, an intelligent remote transmission module is fixedly installed on one side of the water meter body, and inlet pipes and outlet pipes are threadedly connected to both ends of the water meter body through interface nuts. The water meter body is covered with an antifreeze shell, and a heating component is fixedly installed inside the antifreeze shell. A striking component is fixedly fitted on the outer wall of the water inlet pipe.

[0006] As a further embodiment of this utility model, the striking component includes a fixed sleeve, which is fixedly sleeved on the outer wall of the water inlet pipe. The inner cavity of the fixed sleeve is rotatably connected to four sets of rotating rods via pins, and a silicone hammer is fixedly installed at the bottom end of each set of rotating rods.

[0007] As a further embodiment of this utility model, each set of rotating rods has a roller rotatably mounted on its top end via a pin, and a driving block is slidably mounted in the inner cavity of the fixed sleeve, with the roller fitting against the outer wall of the driving block.

[0008] As a further embodiment of this utility model, a threaded tube is rotatably installed inside the fixed sleeve via a bearing, and a drive block is threadedly sleeved on the outer wall of the threaded tube. One end of the threaded tube protrudes from the fixed sleeve and is fixedly sleeved with a transmission gear ring.

[0009] As a further embodiment of this utility model, the antifreeze shell is composed of a top cover and two sets of side shells spliced ​​together, and the three are interlocked with each other. Three sets of mounting blocks are fixedly installed on the outer wall of the top cover, and three sets of corresponding connecting blocks are fixedly installed on the outer wall of the water meter body, and the connecting blocks and mounting blocks are fixedly connected by bolts.

[0010] As a further embodiment of this utility model, the heating assembly includes a heating plate located at the bottom of the inner wall of the two sets of side shells. An insulation layer is fixedly installed on the inner wall of the two sets of side shells, and the insulation layer is located above the heating plate. A storage battery is fixedly installed on the bottom surface of one set of side shells.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When using the remote water meter of this utility model, the silicone hammer of the striking component strikes the pipe at high frequency to prevent the water from freezing. This forms a double antifreeze with the heating component. Compared with the simple heating method, it can reduce the reliance on a single heating method, reduce the risk of freezing due to heating failure, and avoid excessive energy consumption due to heating. At the same time, the silicone material can protect the pipe when striking, making the antifreeze more reliable and taking into account both energy saving and pipe protection.

[0012] 2. When using the remote water meter of this utility model, the antifreeze shell is securely assembled to the outside of the water meter body by splicing, snap-fitting and bolts to form a closed space, which provides a heat preservation environment for the internal heating components, reduces heat loss, ensures heating and antifreeze effect, and the detachable design facilitates subsequent maintenance and repair. At the same time, it can isolate the external low temperature and impurities, protect the water meter body, and help the antifreeze function to function stably. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 In this embodiment of the utility model, a remote water meter with antifreeze function includes a water meter body 1. A dial 2 is fixedly installed on the top of the water meter body 1 for displaying water consumption. An intelligent remote transmission module 3 is fixedly installed on one side of the water meter body 1 for collecting, processing and transmitting water meter metering data to realize intelligent water management such as remote meter reading, water consumption monitoring and abnormal alarm. Both ends of the water meter body 1 are threadedly connected to an inlet pipe 5 and an outlet pipe 6 through an interface nut 4. The water meter body 1 is covered with an antifreeze shell 7. A heating component 8 is fixedly installed inside the antifreeze shell 7, which can effectively prevent the water meter body 1 from freezing due to low temperature. The outer wall of the water inlet pipe 5 is fixedly covered with a knocking component 9. The knocking action of the knocking component 9 prevents the water from freezing and further enhances the antifreeze effect. It should be noted that both ends of the water meter body 1 and the connection ends of the inlet pipe 5 and the outlet pipe 6 are respectively equipped with threaded connection ports. The two ends of the water meter body 1 are connected to the inlet pipe 5 and the outlet pipe 6 by the interface nut 4 to form a threaded fastening connection. The interface nut 4 plays a locking and fixing role to ensure accurate docking and realize the sealed connection between the water meter body 1 and the inlet pipe 5 and the outlet pipe 6, ensuring smooth water flow and completing the metering, while preventing leakage at the connection.

[0021] Please see Figure 1 , Figure 4 , Figure 5 The striking component 9 includes a fixed sleeve 901, which is fixedly sleeved on the outer wall of the water inlet pipe 5. The inner cavity of the fixed sleeve 901 is rotatably connected to four sets of rotating rods 902 via pins. Each set of rotating rods 902 has a silicone hammer 903 fixedly installed at its bottom end. The rotating rods 902 drive the silicone hammers 903 to strike the outer wall of the water inlet pipe 5 to prevent the water from freezing. It should be noted that a rubber inner liner ring 904 is fixedly installed on the inner wall of the fixing sleeve 901 to enhance the fixing effect between the fixing sleeve 901 and the water inlet pipe 5. The rubber inner liner ring 904 is tightly attached to the outer surface of the water inlet pipe 5. The fixing sleeve 901 is firmly fixed to the outer wall of the water inlet pipe 5 by the rubber inner liner ring 904 and adhesive. Each set of rotating rods 902 has a roller 905 mounted on its top end via a pin. A drive block 906 is slidably mounted in the inner cavity of the fixed sleeve 901 to provide the striking power of the silicone hammer 903. The roller 905 is in contact with the outer wall of the drive block 906. It should be noted that the drive block 906 is designed as an inverted cone shape and its surface is provided with an inclined surface. Each set of rotating rods 902 is fixedly connected to the fixed sleeve 901 with a return spring 907. It should also be noted that when the drive block 906 moves quickly, its inclined surface will contact the roller 905 and gradually generate a lateral thrust. After the roller 905 is subjected to force, it drives the rotating rod 902 to rotate around the pin shaft, so that the silicone hammer 903 forms an instantaneous impact on the outer wall of the water inlet pipe 5. Subsequently, when the drive block 906 moves quickly in the opposite direction, the reset spring 907 generates an elastic pull at the same time, pulling the rotating rod 902 to rotate in the opposite direction to reset, and driving the silicone hammer 903 to return to its position quickly. This ensures that the silicone hammer 903 can effectively prevent the internal water from freezing through the high-frequency impact to return to its position cycle, and can also avoid hard damage to the water inlet pipe 5 by virtue of the buffering characteristics of the silicone material. Inside the fixed sleeve 901, a threaded tube 908 is rotatably mounted via a bearing, and a drive block 906 is threadedly sleeved on the outer wall of the threaded tube 908. One end of the threaded tube 908 protrudes from the fixed sleeve 901 and is fixedly sleeved with a transmission gear ring 909. It should be noted that a motor 910 is fixedly installed on the outer wall of the fixed sleeve 901, and a drive gear 911 is fixedly installed on the output shaft of the motor 910. The drive gear 911 meshes with the transmission gear ring 909. The motor 910 controls the drive gear 911 to mesh with the transmission gear ring 909 to drive the threaded tube 908 to rotate back and forth. The rotational motion is converted into the reciprocating motion of the drive block 906 along the threaded tube 908 by the threaded transmission, which provides stable power for the high-frequency striking and return cycle of the silicone hammer 903 and ensures the continuous and reliable operation of the anti-freeze striking function. It should also be noted that a limit ring 912 is fixedly installed at one end of the threaded tube 908 to prevent the drive block 906 from falling off.

[0022] Please see Figure 2 , Figure 3 The antifreeze housing 7 is composed of a top cover 701 and two sets of side covers 702 spliced ​​together, and the three are interlocked with each other. Three sets of mounting blocks 703 are fixedly installed on the outer wall of the top cover 701, and three sets of corresponding connecting blocks 704 are fixedly installed on the outer wall of the water meter body 1. The connecting blocks 704 and the mounting blocks 703 are fixedly connected by bolts to achieve a stable assembly of the antifreeze housing 7 and the water meter body 1. It should be noted that the top cover 701 and the two sets of side shells 702 are respectively provided with a slot and a protrusion on one side. The slot and the protrusion are engaged to achieve a detachable snap-fit, so as to quickly assemble and disassemble the antifreeze shell 7, while ensuring the overall sealing, providing a closed environment for the antifreeze function of the internal heating component 8, and preventing heat loss. It should also be noted that a set of side shells 702 are fixedly installed on the inner wall with temperature control sensors to monitor the ambient temperature inside the antifreeze shell 7 in real time.

[0023] Please see Figure 2 , Figure 3 The heating assembly 8 includes a heating plate 801, which is located at the bottom of the inner wall of two sets of side shells 702. An insulation layer 802 is fixedly installed on the inner wall of the two sets of side shells 702, and the insulation layer 802 is located above the heating plate 801. A storage battery 803 is fixedly installed on the bottom surface of one set of side shells 702. It should be noted that the storage battery 803 is used to power the heating plate 801. The heating plate 801 generates heat to prevent the water meter body 1 from freezing. The insulation layer 802 reduces heat loss. The three work together to ensure the efficient antifreeze effect of the antifreeze shell 7. It should also be noted that the storage battery 803 is electrically connected to the motor 910 and the external mains power through wires to form a dual power supply circuit. Under normal circumstances, the motor 910 is powered by the external mains power, and the storage battery 803 serves as a backup power source. When the mains power is interrupted, the power supply is automatically switched to ensure that the motor 910 continues to work and ensures the stable operation of the relevant functions of the water meter body 1.

[0024] The working principle of this utility model is as follows: When using this utility model, firstly, the water meter body 1 is sealed and connected to the inlet pipe 5 and the outlet pipe 6 through the interface nut 4 to ensure smooth water flow and accurate measurement. Then, the top cover 701 and two sets of side shells 702 are assembled. The antifreeze shell 7 is fixed to the outside of the water meter body 1 through the mounting block 703 and the connecting block 704 with bolts to form a closed space. In daily use, water flows through the inlet pipe 5 into the water meter body 1, and the water consumption is measured by the water meter body 1. The meter 2 displays the data synchronously. In conjunction with the intelligent remote transmission module 3, the data is collected, processed and transmitted to the water system in real time to realize remote meter reading, water consumption monitoring and abnormal alarm. When the temperature sensor installed on the inner wall of the side shell 702 detects that the ambient temperature inside the antifreeze shell 7 drops to a preset value, the battery 803 supplies power to the heating plate 801. The heating plate 801 generates heat to prevent freezing, and works with the insulation layer 802 to reduce heat loss. Immediately, the start motor 910 drives the drive gear 911 to mesh with the transmission gear ring 909, causing the threaded tube 908 to rotate back and forth, and the drive block 906 to move back and forth quickly along the threaded tube 908. When the drive block 906 approaches the limit ring 912, it pushes the rotating rod 902, causing the silicone hammer 903 to strike the water inlet pipe 5 instantly. Conversely, when the drive block 906 moves away from the limit ring 912, the return spring 907 pulls the rotating rod 902 back, forming a cycle of striking. Finally, the storage battery 803, motor 910, heating plate 801, and mains power form a dual power supply circuit through the circuit. It normally uses mains power and automatically switches when the mains power is interrupted, ensuring that all components work continuously and guaranteeing the stability of the water meter function.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
