Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0030] Referring to Figures 1-3The utility model provides an embodiment: power equipment operation state comprehensive monitoring device, including protection shell 1, the main role of protection shell 1 is to protect the inside electrical element from the influence of external environmental factors, such as dust, moisture, mechanical collision etc., thereby prolongs the service life of equipment.

Sensor 4 is installed on mounting plate 3 through fixing assembly, and sensor 4 is used for real -time monitoring the operation state of power equipment, such as current, voltage, temperature, humidity and other parameters, which can timely and accurately feedback the working condition of equipment, provides data support for equipment fault diagnosis, performance evaluation and operation optimization, and helps to guarantee the safe and stable operation of power equipment. Protection shell 1 is provided with heat dissipation assembly inside, and the heat dissipation assembly includes liquid storage tank 5, and the liquid storage tank 5 is used for storing coolant and provides cooling medium for the whole heat dissipation circulating system, and the side wall of liquid storage tank 5 is fixedly connected inside protection shell 1, so that it keeps stable position in protection shell 1, avoids displacement due to vibration and other factors in the equipment operation process, and protection shell 1 is fixedly installed with circulating pump 6 and cooler 8 inside, and the function of circulating pump 6 is to drive the coolant to circulate in the heat dissipation system, so that the coolant can be continuously extracted from liquid storage tank 5 through input pipe 7, cooled after passing through cooler 8, and then sent back to cooling pipe 10 through output pipe 9, to form a continuous heat dissipation circulation, guaranteeing the stability and reliability of heat dissipation effect. Cooler 8 is responsible for cooling the circulating coolant, dissipates the heat absorbed by the coolant to the external environment, so that the coolant can continuously and effectively take away the heat in protection shell 1. The input end of circulating pump 6 is connected with liquid storage tank 5 through input pipe 7, which provides a channel for the coolant to flow from liquid storage tank 5 to circulating pump 6, ensuring that circulating pump 6 can smoothly extract the coolant in liquid storage tank 5, and guaranteeing the normal start and continuous operation of heat dissipation circulation. The output end of circulating pump 6 is connected with cooler 8 through output pipe 9, and output pipe 9 delivers the coolant pressurized by circulating pump 6 to cooler 8, so that the coolant can be cooled in cooler 8, preparing for the subsequent heat dissipation process. Cooling pipe 10 is distributed in protection shell 1, and cooling pipe 10 is fixedly installed on the inner wall of protection shell 1 through fixing block 11, and the coolant flowing in cooling pipe 10 can absorb the heat in protection shell 1, thereby reducing the temperature inside protection shell 1, and fixing block 11 guarantees the firm installation of cooling pipe 10 on the inner wall of protection shell 1, preventing cooling pipe 10 from displacement or falling off due to vibration and other reasons, and affecting the heat dissipation effect.The cooling pipe 10 is connected with the liquid storage tank 5 at one end and connected with the cooler 8 at the other end, and such a connection mode enables the cooling liquid to form a complete circulation loop among the liquid storage tank 5, the cooling pipe 10 and the cooler 8, guarantees the continuity and effectiveness of the heat dissipation system, enables the cooling liquid to continuously circulate heat dissipation, and maintains the temperature stability inside the protective shell 1. The back plate of the protective shell 1 is provided with a heat dissipation fan 12, the heat dissipation fan 12 can accelerate the flow of air inside the protective shell 1, timely discharges the heat generated by the equipment operation outside the protective shell 1, further improves the heat dissipation efficiency, enhances the heat dissipation effect, cooperates with the heat dissipation assembly, and jointly guarantees that the temperature inside the protective shell 1 is within a reasonable range, prevents the equipment from malfunctioning due to overheating. The bottom of the two side plates of the protective shell 1 is provided with an air inlet 13, the air inlet 13 provides a channel for the outside cold air to enter the inside of the protective shell 1, enables the cold air to enter the protective shell 1 under the action of the heat dissipation fan 12, exchanges heat with the internal hot air, thereby reduces the temperature inside the protective shell 1, forms a good air convection, improves the heat dissipation effect, and guarantees the normal operation of the equipment.
[0031] In the use of the device for monitoring, through the installation of multiple sensors 4 inside the protective shell 1, the internal insulation defects of the medium and low voltage switch cabinet equipment, the breaker action characteristic defects, the environmental state and so on are monitored. The sensor 4 as the core component of monitoring can obtain various information inside the switch cabinet equipment in real time and accurately, which is crucial for timely discovering potential insulation problems, ensuring the normal action of the breaker and understanding the influence of environmental factors on the equipment, so as to realize the comprehensive perception of the switch cabinet state, the early warning of faults, effectively reduce the risk of equipment failure, and ensure the stable operation of the power system. The collected data is transmitted to the monitoring center or cloud platform through wired or wireless communication mode. In the monitoring center or cloud platform, the received data will be preprocessed such as data cleaning and filtering to remove noise and invalid data and improve data quality. Then, the data is deeply mined and analyzed by using data analysis algorithms and models, such as comparing and analyzing historical data and real-time data to evaluate whether the operation state of the power equipment is normal. According to the result of data analysis, the operation state of the power equipment is comprehensively evaluated to determine whether the equipment is in normal operation, sub-health state or fault state. When abnormal data or state change is detected, the system will automatically diagnose the fault by comparing with the preset fault threshold and characteristics to judge the type, location and severity of the fault. Once it is diagnosed that there is a hidden danger or a fault in the equipment, the system will immediately issue a warning or alarm signal to notify the relevant operation and maintenance personnel to take timely measures. At the same time, the operation and maintenance personnel can log in the monitoring system through remote terminals such as computers, mobile phones, etc. at any time and anywhere to view the real-time operation state, historical data, alarm information, etc. of the power equipment to realize remote monitoring. In the running process of the sensor 4, the circulating pump 6 is started to pump out the cooling liquid in the liquid storage tank 5, and then the cooling liquid is transported into the cooler 8 for cooling. The main function of the cooler 8 is to reduce the temperature of the cooling liquid. The cooled cooling liquid flows into the cooling pipe 10, which is distributed around the sensor 4 and can fully contact the sensor 4. The function of the cooling pipe 10 is to absorb the heat generated by the sensor 4 during operation. The cooling pipe 10 has good heat conductivity and can quickly and effectively transfer the heat of the sensor 4 to the cooling liquid, so as to realize local cooling of the sensor 4 and prevent heat accumulation on the sensor 4, ensuring that the temperature of the sensor 4 is always within the normal working range. Then the cooling fan 12 is started. The main function of the cooling fan 12 is to generate airflow. The hot air absorbed by the cooling liquid is blown out of the protective shell 1 through the air inlet 13 by the blowing of the cooling fan 12. The cooling fan 12 can accelerate the flow of air inside the protective shell 1, improve the efficiency of heat dissipation, and make the heat absorbed by the cooling liquid quickly exhaust from the protective shell 1, further enhancing the cooling effect of the whole cooling system and creating a good cooling environment for the sensor 4 to ensure the stable operation of the sensor 4.Further, the sensor 4 is cooled, and the sensor 4 can continuously and stably monitor various state information of the medium-low voltage switch cabinet equipment, and a reliable guarantee is provided for safe operation of the power system.
[0032] With reference to Figures 4-5The fixing assembly comprises a fixing plate 14, which serves to provide a stable mounting base for the sensor 4 and ensure that the sensor 4 is firmly fixed on the mounting plate 3. The sensor 4 is fixedly mounted on the fixing plate 14 and indirectly connected to the mounting plate 3 through the fixing plate 14, so as to better monitor the operating state of the power equipment. The fixing plate 14 is fixedly connected with mounting shells 16 on both sides, which are used to accommodate and protect the components inside. The mounting shells 16 are internally provided with clamping blocks 20, which are one of the key components for realizing the detachable cooperation between the fixing plate 14 and the mounting plate 3. The mounting plate 3 is provided with mounting holes 15 corresponding to the clamping blocks 20, which provide the clamping blocks 20 with positions for insertion and positioning. Through the close cooperation with the clamping blocks 20, the connection between the mounting plate 3 and the fixing plate 14 is realized, the installation precision and stability of the entire fixing assembly on the mounting plate 3 are ensured, and the accurate installation position of the sensor 4 in the protective shell 1 is ensured, which is conducive to the accurate monitoring of the operating state of the power equipment by the sensor 4. The mounting shells 16 are rotatably connected with rotating rods 17, one end of which is fixedly connected with connecting blocks 18 inside the mounting shells 16. The connecting blocks 18 serve to connect the rotating rods 17 and the transmission mechanism. The connecting blocks 18 are connected with the clamping blocks 20 through the transmission mechanism, which can convert the movement of the connecting blocks 18 into the linear movement of the clamping blocks 20, so that the rotating rods 17 drive the clamping blocks 20 to move and complete the detachable cooperation with the mounting holes 15. The transmission mechanism makes the operation more labor-saving and convenient, and ensures the accuracy and stability of the movement of the clamping blocks 20 and the reliable work of the fixing assembly. The transmission mechanism comprises rotating plates 19 rotatably connected with the lower parts of the connecting blocks 18. The rotating plates 19 can rotate around the connecting points with the connecting blocks 18 under the driving of the connecting blocks 18, convert the rotating movement of the connecting blocks 18 into the swinging movement of the rotating plates 19, and provide the basis for power transmission and movement conversion for subsequent driving of the clamping blocks 20 to move. The other ends of the rotating plates 19 are rotatably connected with fixed rods 21, which are rotatably connected with the clamping blocks 20. The swinging of the rotating plates 19 can drive the fixed rods 21 to move, and then push the clamping blocks 20 to slide in the mounting holes 15, realize the cooperation and separation of the clamping blocks 20 and the mounting holes 15, and complete the fixing and dismounting operations of the fixing plate 14 and the mounting plate 3.The clamping block 20 is slidably connected inside the mounting hole 15 through the mounting shell 16, and the sliding connection mode ensures that the clamping block 20 can move smoothly in the mounting hole 15, realize accurate cooperation and separation with the mounting hole 15, and the clamping block 20 is symmetrically provided with two, the symmetric arrangement of the two clamping blocks 20 can make the fixing of the fixing plate 14 on the mounting plate 3 more uniform and stable, prevent the fixing plate 14 from being offset or shaken in the horizontal direction, and the spring 23 is arranged between the two clamping blocks 20, the spring 23 provides elastic force for the clamping block 20, the lower part of the clamping block 20 is fixedly connected with the sliding block 22, the sliding block 22 is slidably connected with the bottom of the mounting shell 16, the sliding block 22 can limit the moving direction of the clamping block 20, so that it can only slide along the specific track at the bottom of the mounting shell 16, ensure the linearity and accuracy of the movement of the clamping block 20, prevent the clamping block 20 from being offset or shaken during the movement, so as to ensure that the clamping block 20 can be accurately inserted into and withdrawn from the mounting hole 15, realize the normal function of the fixing assembly.
[0033] When it is necessary to replace and disassemble the sensor 4, first rotate the rotating rod 17, which can provide power and direction guidance for the movement of subsequent components, to drive the connected block 18 to rotate accordingly. The connected block 18 rotates to drive the rotating plate 19 to rotate, which changes its own position and angle, thereby providing a force arm for the fixed rod 21 to push the clamping block 20, so that the fixed rod 21 can produce corresponding displacement with the rotation of the rotating plate 19. Then pull the clamping block 20 to slide through the fixed rod 21, which is an intermediate component connecting the rotating plate 19 and the clamping block 20, and can convert the rotating motion of the rotating plate 19 into the linear sliding motion of the clamping block 20, realize the conversion of force direction, and accurately pull the clamping block 20 to slide in a specific direction in the installation shell 16. The spring 23 is compressed and contracted during the sliding of the clamping block 20, and its main function is to store elastic potential energy and provide a restoring force for the clamping block 20. When the external force disappears, the spring 23 can rely on its own elastic restoring force to push the clamping block 20 back to the initial position, ensuring the normal use and repeated operation performance of the fixed assembly. Thus, the clamping block 20 is separated from the inside of the mounting hole 15, and the clamping block 20 is separated from the mounting hole 15, which is a key step in disassembling the sensor 4. Only when the clamping block 20 is removed from the mounting hole 15, the fixed plate 14 can be fixed and limited, so that the sensor 4 can be removed from the mounting plate 3. At this time, the fixed plate 14 is fixed, which plays a crucial role in the installation and fixation of the sensor 4, and provides a stable support platform for the sensor 4, ensuring that the sensor 4 can maintain a fixed position during normal operation, preventing displacement due to external forces or vibration, and ensuring the accuracy and reliability of data collection by the sensor 4. During disassembly, the fixed plate 14 can still temporarily maintain the position of the sensor 4 after the clamping block 20 is separated from the mounting hole 15, facilitating the operator to remove the sensor 4 from above. The sensor 4 can be removed from above for replacement and maintenance operation. The smooth removal of the sensor 4 is to facilitate subsequent replacement or maintenance work, and through the cooperation of the above series of components, the sensor 4 can be conveniently and quickly disassembled from the installation position, so as to be checked, repaired, replaced, etc. Operation, ensure that the performance of the sensor 4 is always in good condition, and then ensure the normal operation of the entire monitoring system.
[0034] Working principle: when monitoring with the device, the internal insulation defects, circuit breaker action characteristic defects, environmental conditions and the like of the medium and low voltage switch cabinet device are monitored through the sensor 4. The overall perception of the switch cabinet state and the early warning of the fault are realized. In the operation process of the sensor 4, the circulating pump 6 is started to draw the cooling liquid in the liquid storage tank 5, then the cooling liquid is transported into the cooler 8 for cooling, then the cooled cooling liquid flows into the cooling pipe 10, so that the cooling pipe 10 absorbs the heat generated in the operation process of the sensor 4, then the heat dissipation fan 12 is started, the heat absorbed by the cooling liquid is blown out of the protective shell 1 through the air inlet 13 by the blowing of the heat dissipation fan 12, and the heat dissipation effect of the sensor 4 is achieved. When the sensor 4 needs to be replaced and disassembled, first, the rotating rod 17 is rotated to drive the connecting block 18 to rotate, the rotation of the connecting block 18 drives the rotating plate 19 to rotate, then the spring 23 is extruded and contracted by the sliding of the clamping block 20 pulled by the fixed rod 21, so that the clamping block 20 is separated from the installation hole 15, at this time the fixed plate 14 is fixed, the sensor 4 can be taken off from above, and the replacement and maintenance operation is carried out.
[0035] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement and the like made within the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
