Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prepaid water meters, and in particular to a split-type Internet of Things prepaid water meter structure. Background Art
[0002] Prepaid water meters utilize modern microelectronics, sensing technology, and smart stored-value cards to measure water consumption, transmit data, and settle transactions. Through a built-in smart chip and electronically controlled valves, they enable a pay-up-and-use model. Users pre-pay the meter or related management system, and the meter automatically deducts charges based on actual water usage. When the balance is low, the meter issues an alert and automatically shuts off until the balance is depleted, effectively preventing water bill arrears and wasting water resources.
[0003] At present, most of the IoT prepaid water meters on the market have their controllers integrated into the smart water meter body. However, this type of integrated IoT prepaid water meter structure has the following shortcomings during actual use: First, since the controller part is in the underground water meter well, there is a problem of poor communication between the remote terminal and the smart water meter when exchanging data, charging and swiping the card; Second, the temperature in the underground water meter well is low and the humidity is high, and the controller part is prone to moisture, water ingress, electrical corrosion and aging, which will affect the service life of the smart water meter; Third, when reading the meter, it is necessary to move the manhole cover from the underground water meter well, and then lean over to reach into the underground water meter well to observe the data on the display screen, which increases the workload and difficulty of the actual meter reading operation of the meter reader; Fourth, it is more difficult to control the opening and closing of the smart water meter, recharge or maintenance at night, and there are also certain safety hazards.
[0004] In view of this, it is particularly important to design and manufacture a prepaid water meter structure with good waterproof and moisture-proof effects and improve the actual working stability, safety and convenience of the smart water meter in the design, manufacture and actual use of the prepaid water meter. Utility Model Content
[0005] The purpose of this utility model is to solve the problems of traditional integrated Internet of Things prepaid water meters, which are prone to poor communication, aging due to moisture, poor interaction convenience and poor safety in actual use, and to propose a split Internet of Things prepaid water meter structure.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A split-type Internet of Things prepaid water meter structure includes a smart water meter body and a controller installed inside an underground water meter well. The smart water meter body and controller are split structures, and the controller is separately installed on a wall above the ground of the underground water meter well. An electrical connection part for jointly electrically connecting the smart water meter body and the controller is provided between the smart water meter body and the controller.
[0008] As a further description of the above technical solution:
[0009] A front cover is detachably mounted on the front end of the controller, a PCB is mounted on the inner side of the front cover, and waterproof glue covering the PCB is filled between the controller and the front cover.
[0010] As a further description of the above technical solution:
[0011] A display screen is installed on the upper left side of the front end of the PCB, an IC sensing module is installed on the lower left side of the front end of the PCB, a control keyboard is installed on the right side of the front end of the PCB, and a waterproof battery is installed on the rear end of the PCB.
[0012] As a further description of the above technical solution:
[0013] The electrical connection part includes a power socket integrally fixed on the smart water meter body, a power plug installed at the lower end of the PCB and penetrating downward through the controller, and a metal braided cable installed between the power socket and the power plug through a waterproof aviation connector.
[0014] As a further description of the above technical solution:
[0015] The four corners at the rear end of the controller are integrally fixedly connected with mounting ribs, and the mounting ribs are provided with through holes.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0017] In the present utility model, the original integrated prepaid water meter structure is improved into a split structure, and the controller can be externally fixed on a wall or in an electric cabinet. The controller can establish a circuit connection with the smart water meter body through a metal braided cable and a waterproof aviation connector. The user or the meter reader can stand on the underground water meter well to interact with the data of the smart water meter body and perform control operations through the controller. In addition, waterproof glue covering the PCB is injected between the controller and the front cover to prevent external dust, water vapor and impurities from entering the controller. At the same time, the waterproof glue can provide impact protection for the fragile PCB. This structure effectively reduces the occurrence of problems such as poor communication and aging due to moisture during daily use of the prepaid water meter, and effectively reduces the workload and difficulty of meter reading, gate opening control, gate closing control, recharging and maintenance, thereby improving the convenience and efficiency of the actual operation of the prepaid water meter.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-3The utility model provides a technical solution: a split-type Internet of Things prepaid water meter structure, including a smart water meter body 1 and a controller 2 installed inside an underground water meter well 6. The smart water meter body 1 and the controller 2 are split structures, and the controller 2 is separately installed on a wall 7 above the ground of the underground water meter well 6. An electrical connection part for the joint electrical connection between the smart water meter body 1 and the controller 2 is provided between the smart water meter body 1 and the controller 2.
[0025] Specifically, such as Figure 1-3 As shown, the front end of the controller 2 is detachably mounted with a front cover 201, and a PCB 3 is mounted on the inner side of the front cover 201. A waterproof glue 4 covering the PCB 3 is filled between the controller 2 and the front cover 201. The setting of the waterproof glue 4, on the one hand, can seal the gap between the controller 2, the front cover 201 and the PCB 3, which can effectively prevent external dust, impurities and water vapor from entering the controller 2, and provide waterproof and dustproof protection for the display screen 301, IC sensing module 302, control keyboard 303, waterproof battery 304 and power plug 305 on the controller 2. On the other hand, the PCB 3 can be flexibly supported on the inner side of the controller 2 and the front cover 201, which can effectively reduce the occurrence of impact damage to the PCB 3 and the components on the PCB 3. A display screen 301 is mounted on the upper left side of the front end of the PCB 3, which is convenient for users and meter readers to understand the working status of the smart water meter body 1, the amount of water used and the statistics of the remaining water. An IC sensing module 302 is installed at the lower left side of the front end of PCB 3, which can identify IC card data, thereby facilitating the user to control and recharge the smart water meter body 1 through the controller 2. A control keyboard 303 is installed at the right side of the front end of PCB 3 to facilitate the user to input control parameters of the controller 2. A waterproof battery 304 is installed at the rear end of PCB 3 to provide built-in power supply for the prepaid water meter, ensuring that the smart water meter body 1 can work normally outdoors.
[0026] Specifically, such as Figure 1-3 As shown, the electrical connection part includes a power socket 101 integrally fixed on the smart water meter body 1, a power plug 305 installed at the lower end of the PCB 3 and penetrating downwardly through the controller 2, and a metal braided cable 5 installed between the power socket 101 and the power plug 305 through a waterproof aviation connector 501. A wire bobbin braided with metal material is fixed to the outside of the metal braided cable 5, which can support and protect the internal cable, thereby improving the impact resistance, bending resistance and fracture resistance of the metal braided cable 5, thereby improving the stability of the electrical connection between the smart water meter body 1 and the controller 2.
[0027] Specifically, such as Figure 1-3As shown, the four corners of the rear end of the controller 2 are integrally fixedly connected with mounting ribs 202, and the mounting ribs 202 are provided with through holes to facilitate fasteners to pass through the mounting ribs 202 to fix the controller 2 to other fixed objects such as the wall 7, bracket or power cabinet.
[0028] Working principle: During use, after the smart water meter body 1 is pre-installed and fixed in the underground water meter well 6, the controller 2 can be installed and fixed to the wall 7, bracket or power cabinet and other fixed objects through the installation ribs 202 and fasteners according to the actual usage situation. Then, a wiring pipe can be opened or built between the underground water meter well 6 and the fixed object, and the lower end of the metal braided cable 5 can be inserted through the wiring pipe, and the waterproof aviation connector 501 on the metal braided cable 5 is connected to the power socket 101 of the smart water meter body 1 to establish a waterproof circuit connection. Finally, the waterproof aviation connector 501 at the upper end of the metal braided cable 5 is screwed into the power plug 305 at the lower end of the controller 2. At this time, the circuits of the smart water meter body 1 and the controller 2 will be connected, and the working status of the smart water meter body 1 can be observed, controlled and data exchanged through the controller 2.
[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
