Description

Technical Field

[0001] The utility model belongs to the technical field of water supply controllers, in particular to an IC card water supply controller. Background Art

[0002] In the modern water resource management and distribution system, intelligent water supply controllers play a vital role. They not only control the supply and metering of water, but also undertake functions such as data collection, analysis and remote monitoring. With the advancement of science and technology, the requirements for intelligent water supply controllers are constantly increasing. In addition to basic control functions, they are also required to have high precision, low power consumption, high reliability and remote management capabilities. As a key device for modern water resource management and distribution, intelligent water supply controllers are widely used in agricultural irrigation, urban water supply, industrial water use and other fields. With the development of Internet of Things technology, the requirements for controllers are no longer just simple control functions, but are developing towards more intelligent, low energy consumption, high security and remote management. However, traditional intelligent water supply controllers have some obvious limitations in design, which limits their effectiveness and reliability in practical applications.

[0003] However, there are some obvious limitations in the design and performance of traditional water supply controllers, especially in terms of vibration resistance and stability, which directly affect the long-term operating efficiency and maintenance cost of the equipment. The internal structure of traditional water supply controllers is usually fixed directly to the shell without any shock absorption measures. This means that when facing external vibration or impact, the sensitive electronic components inside the controller (such as the control motherboard) will directly bear all the vibration energy, resulting in a series of problems such as cracking of solder joints, damage to circuit boards, and data reading and writing errors, which seriously affect the stability and service life of the equipment. Components such as display screens, card swiping areas, and display lights are usually rigidly fixed, lacking proper buffering and isolation, which can easily cause components to loosen or be damaged when encountering vibration during transportation, installation or operation, affecting the normal function of the equipment. Due to the lack of special shock-absorbing materials and designs, traditional water supply controllers are more susceptible to vibration and impact in harsh outdoor or industrial environments, such as high temperature, humidity, and dusty conditions, resulting in higher equipment failure rates and increased maintenance costs. Due to the rigid connection of the internal structure, once problems caused by vibration occur, it is often necessary to replace the entire motherboard or related components, which not only has a long maintenance cycle but also high costs.

[0043] Shock-absorbing material layer material:

[0044] 1. High elastic rubber material:

[0045] Features: Highly elastic rubber materials (such as EPDM rubber, nitrile rubber or silicone rubber) have excellent elastic recovery performance and energy absorption capacity. They can quickly return to their original shape after being compressed, effectively disperse and absorb external vibration energy, and reduce the impact of vibration on internal electronic components.

[0046] Application: Highly elastic rubber materials are often used to make shock-absorbing material layers around control motherboards, and as core materials for elastic supports, such as cylindrical elastomers. These materials can provide stable and lasting shock absorption effects, ensuring stable operation of the control motherboard under various vibration conditions.

[0047] 2. Polyurethane foam:

[0048] Features: Polyurethane foam is a lightweight, high-damping material with good sound insulation and shock absorption properties. It can effectively absorb vibration energy and reduce vibration transmission. It also has certain heat insulation properties, which helps control the temperature inside the equipment.

[0049] Application: Polyurethane foam is often used to fill the cavity between the inner and outer layers of the housing to form a shock-absorbing material layer to isolate external vibration and impact and protect internal electronic components from damage. In addition, it is also suitable for making shock-absorbing buffer layers to provide additional protection for components such as display screens and card swiping areas.

[0050] Shock-absorbing buffer layer material:

[0051] 1.Silica gel:

[0052] Features: Silicone has excellent elasticity, temperature resistance and chemical stability, and can maintain stable physical properties in a wide temperature range. It also has good damping properties, can effectively absorb vibration energy and reduce vibration transmission.

[0053] Application: Silicone is often used to make shock-absorbing buffer layers between display screens, card swiping areas and other components and the housing. It can effectively absorb external shocks and vibrations, reduce the displacement and damage of these components under vibration conditions, and provide good sealing performance to prevent moisture and dust intrusion.

[0054] 2. Aerogel:

[0055] Features: Aerogel is an ultra-light, high-porosity solid material with excellent thermal insulation, sound insulation and shock absorption properties. It can provide extremely high energy absorption capacity while maintaining low weight and volume, making it an ideal shock-absorbing and cushioning material.

[0056] Application: Although aerogel is relatively expensive, it is an ideal choice as a shock-absorbing buffer layer in applications with extremely high requirements for shock absorption performance. It is especially suitable for protecting sensitive electronic components such as display lights and control motherboards to ensure the stability and reliability of equipment under extreme vibration conditions.

[0062] Elastomer: A cylindrical elastomer made of highly elastic rubber material is preferably used, with a diameter of 5mm and adjustable height. Its elastic coefficient is controlled at around 2000N / m to ensure that the motherboard can effectively absorb and disperse vibration energy when subjected to external vibration, thereby reducing the impact of vibration on the motherboard.

[0063] Fixing bolt: An M3 stainless steel bolt that matches the motherboard mounting hole is used to pass through the motherboard mounting hole and connect to one end of the elastomer. The bolt length is adjusted according to the actual distance between the motherboard and the inner wall of the shell to ensure the stability and shock absorption effect of the motherboard after suspension installation.

[0064] Adjusting nut: The adjusting nut that matches the fixing bolt is used to adjust the distance between the mainboard and the inner wall of the shell to ensure that the mainboard remains level when suspended. The mainboard position can be fine-tuned as needed to adapt to different installation requirements.

[0065] Anti-skid washer: The anti-skid washer placed between the fixing bolt and the motherboard is made of a high friction coefficient material to prevent the motherboard from sliding under the action of the elastomer and enhance the stability of the motherboard installation.

[0066] Locking ring: Located at the other end of the elastomer, the locking ring in contact with the inner wall of the shell is used to fix the elastomer to ensure that the elastomer does not fall off the fixing bolt when subjected to vibration. At the same time, the design of the locking ring also takes into account the heat dissipation performance. It is made of materials with good thermal conductivity, which helps to dissipate heat from the motherboard.

[0067] Furthermore, in the above technical solution, there are multiple elastic support members 14 , and each mounting hole corresponds to an elastic support member 14 .
