[0044] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention are described in detail below with reference to specific drawings.

[0045] It should be noted that all the terms used in the present invention to indicate directionality and position, such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "top", "lower", "lateral", "longitudinal", "center", etc., are only used to explain the relative positional relationship and connection status between the components in a certain state, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0046] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0048] One object of the present invention is to disclose an outdoor smart meter, comprising a meter body 1, a water collector 2, a water storage tank 3, a water channel 4, a heat dissipation structure 5 and a vent cap 6.

[0049] The electric meter body 1 has a double-layer structure, and includes a first shell 101 and a second shell 102. The first shell 101 is arranged outside the second shell 102, and the edges of the first shell 101 and the second shell 102 are connected to form a hollow structure 103;

[0050] The water collector 2 is arranged on the top of the electric meter body 1 and is used to collect rainwater or store water in advance;

[0051] The water storage tank 3 is disposed in the hollow structure 103 and is used to supply water to the heat dissipation structure 5;

[0052] The water channel 4 is used to transfer water or steam between the water storage tank 3 and the heat dissipation structure 5, and between the water storage tank 3 and the water collector 2;

[0053] The heat dissipation structure 5 is arranged outside the first housing 101, and is used to absorb sunlight heat by evaporation of water to reduce the temperature of the meter body 1;

[0054] The vent cap 6 is arranged on the top of the heat dissipation structure 5 , and the vent cap 6 is used to discharge the water vapor generated after the heat dissipation structure 5 absorbs heat.

[0055] The water in the water collector 2 enters the water storage tank 3 through the water channel 4, and then enters the heat dissipation structure 5 through the water channel 4. The water level in the heat dissipation structure 5 is the same as that in the water storage tank 3. The heat dissipation structure 5 evaporates and absorbs heat under the influence of sunlight or other factors, and water vapor is discharged from the ventilation cap 6, which effectively reduces the surface temperature of the first shell 101. The water in the heat dissipation structure 5 will be automatically replenished under the action of gravity.

[0056] The double-layer structural design of the meter body 1 provides a heat-insulating effect. The hollow structure 103 is used to accommodate the water storage tank 3 and other components. The water collector 2 can collect rainwater or pre-stored water to provide a water source for the heat dissipation structure 5, thereby realizing a self-sufficient cooling system and reducing dependence on external water sources. The heat dissipation structure 5 is arranged on the surface of the first shell 101, and can utilize water to absorb heat in high temperature weather and evaporate into water vapor which is discharged from the ventilation cap 6, thereby achieving a better cooling effect and lower energy consumption.

[0057] This arrangement absorbs heat through water evaporation in the heat dissipation structure 5, which can effectively reduce the internal temperature of the meter body 1 and improve the reliability and life of the meter, especially better performance in high temperature environment. At the same time, the water collector 2 is used to collect rainwater or pre-stored water, which reduces dependence on external water sources and realizes a self-sufficient cooling system. This design is not only environmentally friendly and energy-saving, but can also be used in water-scarce or remote areas. The double-layer structure design not only provides good thermal insulation effect, but also makes full use of space to make the overall structure more compact.

[0058] Specifically, the outer surface of the first shell 101 may be a honeycomb structure.

[0059] The honeycomb structure is composed of multiple hexagonal units. This geometric shape provides extremely high rigidity and compressive resistance, allowing the shell to remain stable when subjected to external pressure or impact. Compared with solid materials, the honeycomb structure can significantly reduce weight while providing the same or higher strength, making the entire device lighter. At the same time, the gaps inside the honeycomb structure can be used as air circulation channels, increasing the contact area with the outside air, promoting natural convection and forced convection, and improving heat dissipation efficiency.

[0060] Specifically, the cross section of the water collector 2 is trapezoidal.

[0061] The trapezoidal design increases the water collection area at the top and improves the water collection efficiency. The wider design at the bottom enhances the stability of the overall structure and is suitable for outdoor environments. Moreover, the trapezoidal structure is relatively simple and easy to manufacture and install.

[0062] Specifically, the water volume in the water storage tank 3 does not exceed three quarters of the volume of the hollow structure 103 .

[0063] When the water volume in the water storage tank 3 does not exceed three quarters of the volume of the hollow structure 103, it can be ensured that the water storage tank 3 will not overflow due to excessive water even under extreme rainfall conditions or when the water pump 7 is working abnormally. The extra space is reserved as a safety margin to prevent the system from malfunctioning or being damaged due to excessive water level. At the same time, the air space can help regulate the pressure in the hollow structure 103 to prevent the internal pressure from being too high or too low due to temperature changes or water vapor generation, thereby ensuring the stable operation of the system.

[0064] In addition, water has the property of thermal expansion and contraction, especially in outdoor high temperature environment, the water temperature will increase and the volume will expand. The reserved space can accommodate the water expansion and prevent excessive water pressure or container deformation caused by temperature changes. In cold areas, the reserved space can also prevent water from freezing and expanding to cause damage to the water storage tank 3 and the hollow structure 103.

[0065] Specifically, a plurality of heat dissipation structures 5 are arranged on the outer surface of the first housing 101 , the heat dissipation structures 5 are flat, and the thickness of the water layer in the heat dissipation structures 5 is in the range of 10-20 mm.

[0066] The heat dissipation structure 5 is flat, and the thickness of the internal water layer ranges from 10 to 20 mm. This design ensures that the water layer is thin and uniform. Compared with a thicker water layer, the thinner water layer has a larger evaporation interface and can reach a saturated evaporation state faster, thereby absorbing heat more effectively and evaporating faster.

[0067] Multiple heat dissipation structures 5 are arranged on the outer surface of the first shell 101, which effectively expands the surface area of ​​the heat dissipation structure 5, better absorbs the heat of sunlight irradiating the first shell 101, and prevents heat from being transferred to the inside of the meter body 1 and affecting the performance of the smart meter.

[0068] This arrangement makes full use of the structure of the meter body 1 , making the overall structure compact and the overall appearance beautiful. It can also improve the heat dissipation efficiency of the heat dissipation structure 5 and significantly reduce internal problems of the meter body 1 .

[0069] Preferably, the thickness of the water layer in the heat dissipation structure 5 is in the range of 10-15 mm.

[0070] Specifically, the heat dissipation structures 5 are evenly distributed on the outer surface of the first housing 101 .

[0071] This evenly distributed design can make full use of the external structure of the meter, expand the area of ​​the heat dissipation structure 5, allow the water in the heat dissipation structure 5 to absorb more heat, improve the evaporation efficiency, ensure that the heat is evenly dissipated on the entire external surface of the meter body 1, avoid local overheating, and more efficiently reduce the temperature of the meter body 1.

[0072] The heat dissipation structure 5 may also cover the main areas of the first housing 101 , especially those areas that are prone to generate heat, such as areas with dense electronic components, power modules, etc.

[0073] Specifically, the heat dissipation structure 5 may be in the form of a heat sink or a heat pipe.

[0074] These heat sinks or heat pipes are connected to the water storage tank 3 through the water channel 4 to form a closed water circulation system. The material of the heat dissipation structure 5 should have good thermal conductivity, such as aluminum or copper. These materials can quickly absorb the heat generated by direct sunlight and transfer it to water for evaporation and heat absorption, thereby improving the cooling effect of the heat dissipation structure 5.

[0075] Specifically, a micropore array is arranged on the outer surface of the heat dissipation structure 5 , and the diameter of the micropores ranges from 20 to 200 um.

[0076] By using multiple micropores instead of a single macropore, water can achieve a balance between the static pressure difference and the liquid column under the action of capillary effect, disperse the pressure of liquid outflow, reduce the risk of overflow, further expand the contact area between water and air, and improve the water evaporation effect in outdoor environments, natural customs and direct sunlight, which helps to reduce problems inside the meter body 1.

[0077] Specifically, the water channel 4 includes a first water inlet channel 401, a second water inlet channel 402 and a water outlet channel 403. The first water inlet channel 401 is used to connect the water collector 2 and the water storage tank 3, the second water inlet channel 402 is used for water flowing out of the heat dissipation structure 5 into the water storage tank 3, and the water outlet channel 403 is used for water in the water storage tank 3 to flow into the heat dissipation structure 5.

[0078] A closed water circulation system is formed through the first water inlet 401, the second water inlet 402 and the water outlet 403. This design ensures the continuous flow of water and improves the efficiency of the system. The rainwater collected by the water collector 2 can be automatically replenished into the water storage tank 3 through the first water inlet 401, reducing the dependence on external water sources; the water transported through the water outlet 403 can flow evenly through the heat dissipation structure 5, and then water or water vapor can flow from the heat dissipation structure 5 into the water storage tank 3 through the second water inlet 402 to achieve water circulation.

[0079] The design of setting up water channel 4 not only realizes efficient water circulation and uniform heat dissipation, but also has the advantages of self-sufficiency, environmental protection, energy saving and compact structure, so that the smart meter can operate stably in high temperature outdoor environment, extend service life and reduce maintenance costs.

[0080] Specifically, the water channel 4 is an external independent pipeline or integrated inside the first shell 101 .

[0081] The design of the external pipeline makes the water channel 4 relatively independent from other parts of the meter body 1, which is convenient for installation and maintenance. If a part fails, the corresponding pipeline can be replaced separately without affecting other components. The position and direction of the pipeline can be adjusted according to actual needs to adapt to different installation environments.

[0082] Integrating the water channel 4 into the first shell 101 makes the entire system more compact and does not take up additional space. The design of the internal cavity can better protect the water channel 4 and prevent the external environment, such as ultraviolet rays, physical damage, etc., from affecting the pipeline, making the appearance more tidy without exposed pipelines, thereby improving the overall aesthetics.

[0083] Specifically, the water channel 4 is provided with a plurality of valves for controlling the circulation of water.

[0084] The provision of multiple valves helps to achieve precise control of the water circulation system and helps to improve the automation level of the device.

[0085] Specifically, a water pump 7 is provided in the water storage tank 3, and the water pump 7 is used to drive water circulation.

[0086] The water pump 7 provides power to circulate water between the water storage tank 3, the water outlet 403, the heat dissipation structure 5 and the second water inlet 402. The water supply can ensure that there is sufficient water in the heat dissipation structure 5 to ensure the evaporation of water in the heat dissipation structure 5, so that it can continuously take away the heat generated inside the meter body 1 and keep the internal temperature of the meter within a safe range.

[0087] The water pump 7 can be used in conjunction with a temperature sensor. It will automatically start when the internal temperature of the meter exceeds a set value and automatically stop when the temperature drops to a safe range. It can be controlled by a timer or a microprocessor to automatically start and stop the water pump 7 according to a preset time interval to optimize energy consumption.

[0088] Specifically, it also includes a control module, a collection module and a communication module.

[0089] The acquisition module is used to detect the temperature of the meter body 1, the liquid level in the water storage tank 3 and the heat dissipation structure 5, and the pressure in the hollow structure 103;

[0090] The control module is used to control the operation of the water circulation system and the cooling system;

[0091] The communication module is used for information transmission between the control module, the acquisition module, the water circulation system and the cooling system.

[0092] The acquisition module is used to detect the temperature of the meter body 1, the liquid level height in the water storage tank 3 and the heat dissipation structure 5, and the pressure in the hollow structure 103. The acquisition module may include a temperature sensor, a liquid level sensor and a pressure sensor. These sensors monitor relevant parameters in real time and transmit data to the control module.

[0093] The control module is used to control the operation of the water circulation system and the heat dissipation system. It can automatically adjust the working state of the water pump 7 and the opening and closing of the vent cap 6 according to the data provided by the acquisition module. The control module can integrate a microprocessor, a sensor interface and an actuator interface to realize intelligent control of the entire system.

[0094] The communication module is used to transmit information between the control module, acquisition module, water circulation system and cooling system. It can realize wireless or wired transmission of data to ensure the coordinated work between various modules. The communication module can support multiple communication protocols, such as Wi-Fi, Bluetooth, LoRaWAN, etc., to facilitate remote monitoring and management.

[0095] This setting improves the intelligence level of the system. Through automatic control, the working state of the water pump 7 can be adjusted according to actual needs, avoiding unnecessary energy consumption and extending the life of the equipment. The data of the acquisition module can also be transmitted to the remote monitoring center in real time to facilitate remote monitoring and management. When an abnormal situation is detected, the communication module can send an alarm message to promptly notify maintenance personnel for processing, thereby improving the reliability and safety of the system.

[0096] Another object of the present invention is to disclose a method for controlling an outdoor smart meter, the specific steps of which are as follows:

[0097] S1: After the acquisition module detects that the temperature inside the meter body 1 is higher than the set temperature, the temperature information is fed back to the control module;

[0098] S2: After receiving the signal, the control module controls the water pump 7 to work, and the water in the water storage tank 3 enters the heat dissipation structure 5 through the water outlet 403;

[0099] S3: After the liquid level reaches the set height, the acquisition module feeds back the signal to the control module, and the control module controls the water pump 7 to stop working;

[0100] S4: After the water pump 7 stops working, the control module controls the vent cap 6 to open;

[0101] S5: When the liquid level in the heat dissipation structure 5 drops to a set height and the temperature of the electric meter is still higher than the set value, the acquisition module feeds back the signal to the control module, and the control module controls the water pump 7 to supply water to the heat dissipation structure 5;

[0102] S6: After the liquid level reaches the set height, the acquisition module feeds back the signal to the control module, and the control module controls the water pump 7 to stop working;

[0103] S7: Repeat steps S1-S6 until the acquisition module detects that the temperature inside the meter body 1 is lower than the set temperature.

[0104] Through the closed-loop control system, the working state of the water pump 7 can be dynamically adjusted according to the changes in the actual temperature and liquid level to ensure that the temperature of the meter body 1 is always kept within a safe range. By using automatic control, the working state of the water pump 7 can be adjusted according to actual needs to avoid unnecessary energy consumption and extend the life of the equipment. At the same time, accurate temperature and liquid level detection can be used to ensure efficient operation of the system and avoid overcooling or insufficient cooling.

[0105] This setting can effectively reduce the internal temperature in a high temperature environment, can meet the needs of long-term stable operation, ensure reliable operation under various environmental conditions, and improve the reliability and service life of the smart meter.

[0106] Specifically, when the temperature inside the meter body 1 is lower than the set temperature, the vent cap 6 is in a closed state.

[0107] When the internal temperature of the meter body 1 is lower than the set temperature, the heat dissipation demand is reduced. At this time, closing the vent cap 6 can prevent water vapor from escaping through the vent cap 6. By reducing unnecessary water evaporation, the amount of water in the water storage tank 3 can be preserved, thereby extending the self-sufficiency time of the system and reducing dependence on external water sources. At the same time, the entire system can be more energy-efficient and reduce energy consumption under low temperature conditions, prevent metal parts from rusting and corrosion, protect equipment materials, and extend their service life.

[0108] Specifically, when the temperature inside the meter body 1 is lower than the set temperature and the internal pressure of the hollow structure 103 exceeds the set value, the control module controls the vent cap 6 to open.

[0109] When the temperature inside the meter body 1 is lower than the set temperature and the internal pressure of the hollow structure 103 exceeds the set value, the excessive pressure is quickly released to prevent equipment damage, protect system safety, ensure the normal operation of the water circulation system, and enable the device to better cope with temperature and air pressure fluctuations, ensuring that the system is always in the best working condition, thereby enhancing the reliability and safety of the system.

[0110] Specifically, when the liquid level in the water storage tank 3 is lower than the set height, the acquisition module feeds back the liquid level information to the control module, and the control module controls the valve on the waterway to open, and the water in the water collector 2 flows into the water storage tank 3 until the liquid level in the water storage tank 3 reaches the set height.

[0111] When the liquid level in the water storage tank 3 is lower than the set height, the design of automatic water replenishment can maintain the water volume, stabilize the water supply, prevent heat dissipation failure, and enhance the reliability and safety of the system through automatic control and fault prevention.

[0112] Specifically, it also includes a remote terminal for sending an early warning message to a remote monitoring center or a user.

[0113] The design of the remote terminal for sending early warning messages to the remote monitoring center or users can instantly notify abnormal situations, ensure rapid response, improve the safety of the system, realize preventive maintenance and remote diagnosis, reduce the frequency and cost of on-site maintenance, help provide multiple security guarantees, and ensure the stable operation of the system.

[0114] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
