Description

Technical Field

[0001] This utility model relates to the field of detector technology, and in particular to a controller with ultra-high temperature and water leakage detection. Background Technology

[0002] The detection controller is a general-purpose detector that serves industries such as data centers, industry, medical, buildings, energy, cold chain, ships, and agriculture. It plays a vital role in these industries, significantly improving safety and reducing losses. It is mainly used for security protection, equipment protection, and environmental monitoring.

[0003] In the over-temperature and leakage detection controller, over-temperature detection measures the ambient or object temperature. When the external photoresistor value exceeds a set value (e.g., 4.8KΩ), a relay is triggered, closing a valve or opening a ventilation system to lower the current temperature and maintain a suitable temperature within a certain range. Leakage detection measures ambient humidity or liquid levels. When the external resistance value is less than 10KΩ, a relay activates, opening a valve or shutting off the power to ensure personnel safety.

[0004] The existing technical solutions have the following shortcomings:

[0005] Firstly, in industrial manufacturing, the turning on and off of air conditioners and dehumidifiers is generally done by monitoring equipment displaying the current temperature and humidity, with personnel then deciding whether to switch the equipment on or off based on standards. However, this process can sometimes be delayed. This can lead to the equipment operating continuously under high temperature, high humidity, and water leakage conditions, causing unnecessary wear and short circuits. Controllers with over-temperature and water leakage detection can monitor the surrounding environment and equipment based on pre-set parameter values. When a set threshold temperature is exceeded, a relay will activate the corresponding equipment to lower the temperature. When a water leakage is detected, the relay will forcibly cut off power, ensuring that personnel and equipment operate in a relatively safe environment.

[0006] Secondly, the controller with ultra-high temperature and leakage detection is a customized product. Its detachable design allows for additions or subtractions based on customer needs. Customers can easily remove unnecessary functions for specific usage scenarios, making the product more tailored to their actual needs and avoiding resource waste caused by functional redundancy. Simultaneously, the detachable design offers significant practical advantages. During daily use, when components malfunction or require maintenance, this design facilitates quick and accurate repair and replacement by staff. It eliminates the need for complex disassembly of the entire controller; only the faulty component needs individual attention, greatly improving maintenance efficiency and reducing costs.

[0007] Therefore, we need to design a controller based on ultra-high temperature and leakage detection to solve the problems mentioned above. Utility Model Content

[0008] The technical problem to be solved by this utility model is that existing detection controllers do not have the defects of simultaneously having ultra-temperature and leakage detection. This utility model proposes a controller with ultra-temperature and leakage detection.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a controller with ultra-high temperature and leakage detection, including a controller body, the controller body is composed of a face mask, a top cover plate, a shell, and a side cover plate, the PCB circuit board is located inside the controller body, the face mask is pasted together with the top cover plate and fixed with the relevant slots of the shell, the connector position of the PCB circuit board is connected to a terminal, and a first connecting plate and a leakage detector are fixed on the side of the face mask respectively.

[0010] Preferably, a temperature sensor and a second connecting plate are fixed to the outer sides of the first connecting plate and the water leakage detector, respectively, and positioning blocks are fixed to the inner sides of the first connecting plate and the water leakage detector, respectively. A positioning groove is opened on the outer side of the controller body, and the positioning groove is engaged with the positioning block.

[0011] Preferably, the temperature sensor and the second connecting plate are respectively provided with a fixing mechanism, and four fixing mechanisms are provided. Each fixing mechanism includes an internal groove, which is provided inside the temperature sensor and the second connecting plate. A pull rod is movably connected inside the internal groove, and a movable block is fixed inside the pull rod. A pull ring is fixed outside the pull rod, and a spring is wound around the outside of the pull rod. A locking block is fixed inside the movable block, and a locking groove is opened on the outside of the positioning groove, and the locking groove is engaged with the locking block.

[0012] Preferably, the size of the locking blocks is equal to the size of the locking grooves, and the sizes of the locking blocks and locking grooves are both trapezoidal.

[0013] Preferably, the controller body includes a temperature-sensitive element (thermostat, thermocouple) and a mechanical actuator (relay, solenoid valve). The controller body also includes a water leakage sensor, which typically consists of two conductive cores supported by a spiral frame to form an insulating structure.

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] 1. In the working mechanism of the over-temperature and leakage detection controller, the over-temperature detection module is mainly responsible for real-time monitoring of the temperature status of the environment or object. When the resistance of the external photoresistor connected to this module increases due to temperature changes and exceeds a preset threshold of kilohms, the system will trigger a relay to act. This action will cause the valve to close or the ventilation system to start. Through the above measures, the temperature of the current environment or object can be effectively reduced, ensuring that it is always maintained within a relatively moderate and safe temperature range, avoiding various potential risks caused by excessive temperature. The leakage detection module focuses on detecting the ambient humidity or the presence of liquid. When the resistance of the external resistor decreases due to increased ambient humidity or liquid intrusion, and falls below the set threshold of kilohms, the relay will also be triggered to perform corresponding actions. At this time, the system may choose to open the valve to drain the accumulated water or turn off the power to cut off potential electrical hazards, depending on the specific application scenario and safety requirements. In this way, the safety of personnel and the normal operation of equipment are protected to the greatest extent, preventing safety accidents caused by leakage problems.

[0016] 2. By enabling initial positional definition of the components consisting of the first connecting plate and the leak detector, this locking structure, through precise geometric matching, quickly establishes the relative positional relationship between the two in the initial assembly stage, providing a stable benchmark for subsequent fixing operations. This effectively avoids problems such as component offset or misalignment during installation. When the operator applies external force to pull the pull ring, the elastic properties of the spring play a key role and generate a rebound force when the force is released, pushing the locking block to precisely engage in the locking groove. This engagement action forms a reliable locking mechanism. This design concept not only helps to promptly detect and eliminate potential faults, but also extends the actual service life of the components through a convenient maintenance mechanism, fully releasing their value and ensuring reliable performance in long-term industrial applications or equipment operation.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] To address the technical challenge of overcoming the limitation of existing detection controllers that do not simultaneously possess over-temperature and leakage detection capabilities, the following solution is disclosed, as detailed below. Figures 1-6 As shown:

[0027] A controller with ultra-high temperature and leakage detection includes a controller body 9, which is composed of a face mask 1, a top cover plate 2, a housing 4, and a side cover plate 5. A PCB circuit board 3 is located inside the controller body 9. The face mask 1 is pasted together with the top cover plate 2 and fixed with the relevant slots of the housing 4. A terminal 6 is connected to the connector position of the PCB circuit board 3. A first connecting plate 7 and a leakage detector 10 are fixed to the side of the face mask 1 respectively.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the introduction of overheat detection can quickly and effectively handle situations where the temperature is too high. At the same time, the introduction of leak detection can safely and effectively ensure the safety and stability of personnel and equipment.

[0029] Temperature sensor 8 and second connecting plate 11 are fixed to the outer sides of the first connecting plate 7 and the water leakage detector 10, respectively. Positioning blocks are fixed to the inner sides of the first connecting plate 7 and the water leakage detector 10, respectively. Positioning grooves 12 are opened on the outer side of the controller body 9, and the positioning grooves 12 are engaged with the positioning blocks.

[0030] Specifically, such as Figure 4 As shown, by utilizing the engagement connection between the positioning slot 12 and the positioning block, the relative positional relationship between the two can be quickly established in the initial stage of assembly, providing a stable reference for subsequent fixing operations and effectively avoiding problems such as component offset or misalignment during installation.

[0031] The temperature sensor 8 and the second connecting plate 11 are respectively provided with fixing mechanisms. There are four fixing mechanisms. The fixing mechanism includes an internal groove 13, which is provided inside the temperature sensor 8 and the second connecting plate 11. A pull rod 15 is movably connected inside the internal groove 13. A movable block 16 is fixed inside the pull rod 15. A pull ring 19 is fixed outside the pull rod 15. A spring 14 is wound around the outside of the pull rod 15. A locking block 17 is fixed inside the movable block 16. A locking groove 18 is opened on the outside of the positioning groove 12. The locking groove 18 is engaged with the locking block 17.

[0032] Specifically, such as Figure 6 As shown, by using the fixing mechanism, the first connecting plate 7 and the leakage detector 10 can be quickly disassembled and assembled, which extends the actual service life of the components, fully releases their use value, and enables them to maintain reliable performance in long-term industrial applications or equipment operation.

[0033] The size of the locking block 17 is equal to the size of the locking groove 18, and the sizes of the locking block 17 and the locking groove 18 are both set to be trapezoidal;

[0034] Specifically, such as Figure 4 As shown, by using the trapezoidal shape of both the locking block 17 and the locking groove 18, the contact area can be extended, making the fixing mechanism more stable.

[0035] The controller body 9 contains temperature-sensitive elements such as thermistors and thermocouples, as well as mechanical actuators such as relays and solenoid valves. The controller body 9 also contains a water leakage sensor, which is usually composed of two conductive cores supported by a spiral frame to form an insulating structure.

[0036] Specifically, such as Figure 1As shown, temperature-sensitive elements such as thermistors and thermocouples, along with mechanical actuators like relays and solenoid valves, are installed inside the device to monitor temperature changes in real time. When the temperature exceeds a set threshold, the device triggers a protection mechanism, cutting off the power or activating other protective measures. Mechanical leak detection devices typically include a leak sensor, a controller, and connecting cables. The leak sensor usually consists of two conductive cores supported by a spiral frame, forming an insulating structure. When liquid comes into contact with the conductive cores, it creates a low-resistance path, changing the circuit's resistance. The controller monitors these resistance changes and triggers an alarm when an anomaly is detected.

[0037] In this embodiment, firstly, high-precision temperature sensors 8 monitor the internal temperature of the equipment in real time. These sensors can detect minute temperature changes and transmit signals to the main controller or backup protection system. When an abnormal temperature is detected, the signal is transmitted to the main controller or backup protection system. If the main controller fails, the over-temperature plate serves as a backup protection measure, capable of independently completing temperature detection and protection tasks. Once the temperature exceeds the set value, mechanical actuators such as relays and solenoid valves are triggered to perform operations such as cutting off the power, shutting down the heating element, or starting the cooling system to quickly reduce the temperature and prevent equipment damage or sample burnout. Simultaneously, a water leakage sensor, typically composed of two conductive cores supported by a spiral frame to form an insulating structure, is used. When liquid comes into contact with the conductive cores, a low-resistance path is formed, thereby changing the circuit's resistance value. The controller is responsible for monitoring resistance changes and triggering an alarm when an abnormality is detected.

[0038] Secondly, when it is necessary to disassemble and assemble the first connecting plate 7 and the water leakage detector 10, the positioning block is engaged with the positioning groove 12. At this time, pulling the pull ring 19 will cause the locking block 17 to be inserted into the locking groove 18 under the elastic action of the spring 14, thereby achieving the effect of locking and fixing. This facilitates the quick disassembly and assembly of the first connecting plate 7 and the water leakage detector 10, allowing for their inspection and replacement, and extending their service life and value.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
