Description

Technical Field

[0001] This application relates to the field of power distribution equipment technology, and in particular to a monitoring mechanism and a power distribution switch cabinet. Background Technology

[0002] For example, a power distribution cabinet with a monitoring and alarm mechanism, disclosed in publication (announcement) number CN214478930U, includes a power distribution cabinet, a waterproof base, and a monitoring and alarm mechanism. The monitoring and alarm mechanism is welded to the upper end of the power distribution cabinet, and the waterproof base is welded to the lower end. The cabinet door is hinged to the front of the power distribution cabinet, and a control panel is embedded on one side of the cabinet door. A control switch is embedded on the cabinet door below the control panel. The beneficial effects are: by setting up a monitoring and alarm mechanism, the internal temperature of the power distribution cabinet can be quickly and effectively monitored, and smoke can be quickly detected in the event of an internal fire. An alarm can be triggered by sound and light, increasing safety. It allows staff to react quickly, cut off power and extinguish fires, and stop losses in time. Moreover, the waterproof base and waterproof cavity prevent water from entering the power distribution cabinet and affecting the use of internal electrical components while ensuring ventilation, thus improving the protection effect.

[0003] However, based on the working principle proposed in the aforementioned patent, the applicant believes that during use, the temperature sensor is fixedly installed on the inner wall of the top of the distribution cabinet. However, hot air has the characteristic of rising; during the operation of the distribution cabinet, the heat generated inside causes the hot air to rise and accumulate at the top. Therefore, the temperature measured by the temperature sensor installed on the inner wall of the top will be higher than the actual average temperature at other locations inside the distribution cabinet, failing to accurately reflect the overall temperature of the distribution cabinet and potentially leading to misjudgment of the cabinet's temperature. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a monitoring mechanism and a power distribution switch cabinet that can improve the accuracy of temperature detection inside the power distribution cabinet and reduce the misjudgment rate of temperature inside the power distribution cabinet.

[0005] This application provides the following technical solution: In a first aspect, embodiments of this application provide a monitoring agency, the monitoring agency comprising: An environmental monitoring component, the environmental monitoring component including at least one environmental monitoring element, the environmental monitoring element being used at least to detect temperature; A position adjustment assembly, the position adjustment assembly including a first adjustment member connected to all the environmental monitoring devices, the first adjustment member being used to adjust the position of all the environmental monitoring devices in a first direction.

[0006] In some embodiments of the first aspect, the position adjustment assembly further includes a second adjustment member connected to the first adjustment member, the second adjustment member being used to adjust the position of the first adjustment member in a second direction, the second direction being intersecting the first direction.

[0007] In some embodiments of the first aspect, the first adjusting member includes: A first drive unit and a pair of cross linkages are hinged at the middle of the pair of cross linkages. The tops of the pair of cross linkages are connected to the first drive unit. At least one of the cross linkages is provided with the environmental monitoring device at its bottom. The first drive unit is used to drive the tops of the pair of cross linkages to move away from or towards each other, so as to move the bottoms of the pair of cross linkages in the first direction.

[0008] In some embodiments of the first aspect, the first driving unit includes: A drive shaft has a forward threaded section and a reverse threaded section along its axial direction, with the threads of the forward threaded section and the reverse threaded section having opposite directions; wherein the forward threaded section is threadedly connected to the top of one of the cross link portions, and the reverse threaded section is threadedly connected to the top of the other cross link portion. A first driving element is connected to the transmission shaft. The first driving element is used to drive the transmission shaft to rotate, so as to cause the tops of the pair of cross links to move away from or towards each other.

[0009] In some embodiments of the first aspect, the second adjusting member includes: The second drive unit and the rotating shaft unit are connected. The rotating shaft unit is connected to the first adjusting member. The second drive unit is used to drive the rotating shaft unit to rotate, so as to drive the first adjusting member to move along the second direction.

[0010] In some embodiments of the first aspect, the second drive unit includes: A second drive element, a gear, and a rack are provided. The second drive element is connected to the rack, and the gear meshes with the rack. The second drive element can drive the rack to move, thereby causing the gear to rotate. The gear is connected to the rotating shaft.

[0011] In some embodiments of the first aspect, the second drive unit further includes a limiting element having a fixed end and a telescopic end, the telescopic end being capable of telescopic movement relative to the fixed end, the telescopic end being connected to the rack, the rack forming a limiting groove extending along the extension direction of the rack, and the limiting element and the limiting groove being slidably engaged.

[0012] In some embodiments of the first aspect, the first direction and the second direction are arranged perpendicularly.

[0013] Secondly, this application also provides a power distribution switch cabinet, which includes a cabinet body and a monitoring mechanism as described in any of the above embodiments. The height direction of the cabinet body is parallel to the first direction, and the movement range of the environmental monitoring device is located within the cabinet body.

[0014] In some embodiments of the second aspect, the cross-section of the cabinet is arranged parallel to the second direction.

[0015] The embodiments of this application have the following advantages: This application provides a monitoring mechanism comprising at least one environmental monitoring component (such as a temperature sensor) for real-time detection of environmental parameters (such as temperature) inside a power distribution cabinet. In traditional solutions, the sensor is fixedly installed on the top of the power distribution cabinet, making it susceptible to the accumulation of hot air and resulting in inaccurate measurements. This application, however, utilizes movable monitoring, providing a wider monitoring coverage and avoiding data deviation from single locations. A first adjusting component (such as an electric slide rail or stepper motor) drives the environmental monitoring component to move in a first direction (such as the vertical direction), thereby dynamically adjusting the sensor's position. For example, during the initial operation of the power distribution cabinet, the sensor can be positioned in the center to monitor the average temperature; when a localized temperature increase is detected, the adjusting component can control the sensor to move up and down to track heat sources or verify the uniformity of temperature distribution.

[0016] Therefore, by dynamically adjusting the sensor positions or distributing monitoring at multiple points, the problem of artificially high top temperatures caused by rising hot air can be avoided, providing a more accurate reflection of the overall or critical temperature status within the distribution cabinet. Traditional fixed sensors may falsely trigger alarms due to localized high temperatures, while this solution can eliminate occasional anomalies through mobile verification or data fusion (such as averaging from multiple sensors), reducing unnecessary maintenance interventions. Monitoring positions can be flexibly adjusted according to the internal structure of the distribution cabinet, heat dissipation conditions, or seasonal changes to adapt to different operating conditions. For example, in summer, the monitoring focus can be shifted to areas with weak heat dissipation. Environmental monitoring components can integrate sensors for smoke, humidity, etc., achieving dynamic monitoring of multiple parameters through the same adjustment component, improving comprehensive early warning capabilities.

[0026] In related technologies, such as the power distribution cabinet with a monitoring and alarm mechanism disclosed in CN214478930U, the power distribution cabinet includes a power distribution cabinet, a waterproof base, and a monitoring and alarm mechanism. The monitoring and alarm mechanism is welded to the upper end of the power distribution cabinet, and the waterproof base is welded to the lower end of the power distribution cabinet. The cabinet door is hinged to the front of the power distribution cabinet, and a control panel is embedded on one side of the cabinet door. A control switch is embedded on the cabinet door below the control panel. The beneficial effects are: by setting up a monitoring and alarm mechanism, the internal temperature of the power distribution cabinet can be quickly and effectively monitored, and smoke can be quickly detected when a fire occurs inside. An alarm is triggered by an audible and visual alarm, which increases the safety of use. It allows staff to react quickly, cut off the power and extinguish the fire, and stop the damage in time. Moreover, the waterproof base and waterproof cavity provide waterproofing, and while ensuring ventilation, prevent water from entering the power distribution cabinet and affecting the use of internal electrical components, thereby improving the protection effect.

[0027] However, based on the working principle proposed in the aforementioned patent, the applicant believes that during use, the temperature sensor is fixedly installed on the inner wall of the top of the distribution cabinet. However, hot air has the characteristic of rising; during the operation of the distribution cabinet, the heat generated inside causes the hot air to rise and accumulate at the top. Therefore, the temperature measured by the temperature sensor installed on the inner wall of the top will be higher than the actual average temperature at other locations inside the distribution cabinet, failing to accurately reflect the overall temperature of the distribution cabinet and potentially leading to misjudgment of the cabinet's temperature.

[0028] As shown in Figure 1, Figure 2 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides a monitoring mechanism 100, which includes an environmental monitoring component and a position adjustment component. The environmental monitoring component includes at least one environmental monitoring element 140, which is used to detect temperature at least. The position adjustment component includes a first adjustment element connected to all environmental monitoring elements, which is used to adjust the position of all environmental monitoring elements 140 in a first direction.

[0029] In these embodiments, this application provides a monitoring mechanism 100 for a power distribution switchgear, aiming to solve the technical problem in the prior art where temperature sensors are fixedly installed on the top of the power distribution cabinet, leading to inaccurate temperature detection and easy misjudgment. This embodiment, by setting an adjustable environmental monitoring component, taking the first direction as the vertical direction as an example, allows it to move vertically inside the power distribution cabinet, thereby achieving dynamic monitoring of the temperature in different height areas. This effectively avoids the phenomenon of higher top temperatures caused by hot air rising, significantly improving the representativeness and accuracy of temperature detection.

[0030] In this embodiment, the environmental monitoring component 140 is an integrated environmental sensor module, specifically including a temperature sensor, a humidity sensor, and a smoke sensor. The temperature sensor uses a high-precision NTC thermistor or a digital DS18B20 sensor, possessing good response speed and long-term stability; the humidity sensor monitors humidity changes inside the cabinet to prevent condensation from affecting electrical safety; and the smoke sensor detects smoke in the early stages of a fire, working in conjunction with an audible and visual alarm to provide early warning.

[0031] The environmental monitoring component 140 is encapsulated in a high-temperature resistant and flame-retardant protective housing. The housing surface is provided with vent holes to ensure that the sensor is in full contact with the air inside the cabinet, while preventing dust and moisture from directly entering.

[0032] For example, there are two environmental monitoring devices 140. One is a temperature sensor and the other is a humidity sensor.

[0033] The position adjustment component is used to drive the environmental monitoring component to adjust its position in the first direction (i.e., the vertical direction), thereby enabling temperature sampling of different height areas within the distribution cabinet.

[0034] In this embodiment, the first adjusting component is a lead screw transmission mechanism, including a stepper motor, a lead screw shaft, a nut slider, and a guide rail. The stepper motor is fixedly installed on the inner wall of the top of the distribution cabinet, and its output shaft is connected to the lead screw shaft to drive the lead screw shaft to rotate; the nut slider is threadedly engaged with the lead screw shaft and slidably connected to the guide rail to ensure smooth movement; the environmental monitoring component is fixedly installed on the nut slider and moves up and down along the lead screw shaft with it.

[0035] The control unit (which can be integrated into the control panel) has a preset timer program or determines whether to activate position adjustment based on real-time temperature differences. For example, it can control a stepper motor to move once every hour, causing the environmental monitoring component to rise from the bottom to the top of the cabinet 200mm, continuously collecting temperature data from multiple points, and calculating the average or weighted average as a reference value for the actual temperature inside the distribution cabinet. It can also automatically move the sensor down to the middle or lower area for retesting if the top temperature is detected to be consistently higher than a set threshold, to rule out false alarms caused by localized overheating.

[0036] In other alternative embodiments, the first adjusting member may also be driven by a linear motor, a pneumatic push rod, or a gear 170 rack 180 mechanism, etc., which can realize linear reciprocating motion, and all of these are within the protection scope of this utility model.

[0037] During normal operation of the power distribution switchgear, the environmental monitoring component of the monitoring mechanism 100 can be initially positioned in the middle of the cabinet 200. The control system activates the first adjusting component according to a preset cycle, causing the environmental monitoring component to move at a uniform speed in the vertical direction, continuously collecting temperature data at different heights during the movement. The central processing unit analyzes and processes the collected data, such as averaging, removing outliers, or establishing a temperature gradient model, thereby more accurately reflecting the overall thermal distribution state inside the power distribution cabinet.

[0038] Compared to the existing design where the temperature sensor is fixed to the top, the monitoring mechanism 100 provided in this embodiment has the following significant advantages: By dynamically adjusting the sensor position, interference from hot air accumulation on the measurement results is avoided, effectively reducing the temperature misjudgment rate; the combination of multi-point sampling and data analysis improves the judgment accuracy of the fire early warning system; the sampling strategy can be adjusted according to different power distribution cabinet structures and load conditions, exhibiting good versatility and scalability.

[0039] In other words, the environmental monitoring component consists of at least one environmental monitoring element 140 (such as a temperature sensor) for real-time detection of environmental parameters (such as temperature) inside the distribution cabinet. In traditional solutions, the sensor is fixedly installed on the top of the distribution cabinet, which is susceptible to the accumulation of hot air, leading to inflated measurement values. This application, however, utilizes movable monitoring, providing a large monitoring coverage area and avoiding data deviation from a single location. The environmental monitoring element 140 is driven to move in a first direction (such as the vertical direction) by a first adjusting component (such as an electric slide rail or a stepper motor), thereby dynamically adjusting the sensor's position. For example, in the initial stage of operation of the distribution cabinet, the sensor can be located in the middle to monitor the average temperature; when a local temperature increase is detected, the adjusting component can control the sensor to move up and down to track heat sources or verify the uniformity of temperature distribution.

[0040] Therefore, by dynamically adjusting the sensor position or distributing monitoring at multiple points, the problem of artificially high top temperatures caused by rising hot air can be avoided, providing a more accurate reflection of the overall or critical temperature status within the distribution cabinet. Traditional fixed sensors may falsely trigger alarms due to localized high temperatures, while this solution can eliminate occasional anomalies through mobile verification or data fusion (such as multi-sensor averaging), reducing unnecessary maintenance interventions. The monitoring position can be flexibly adjusted according to the internal structure of the distribution cabinet, heat dissipation conditions, or seasonal changes to adapt to different operating conditions. For example, in summer, the monitoring focus can be shifted to areas with weak heat dissipation. The environmental monitoring component 140 can integrate sensors for smoke, humidity, etc., achieving dynamic monitoring of multiple parameters through the same adjustment component, improving comprehensive early warning capabilities.

[0041] In some embodiments, the position adjustment assembly further includes a second adjustment member connected to the first adjustment member, the second adjustment member being used to adjust the position of the first adjustment member in a second direction, the second direction being intersecting the first direction.

[0042] In these embodiments, in order to achieve more comprehensive and multi-dimensional dynamic monitoring of the internal environment of the power distribution cabinet, this application also provides an improved monitoring mechanism 100. Its position adjustment component can not only adjust the position of the environmental monitoring component in the first direction (such as the vertical direction), but also adjust the position in the second direction (such as the horizontal direction) that intersects with the first direction by adding a second adjustment component, thereby realizing free movement in a two-dimensional plane, expanding the monitoring range, and improving the spatial representativeness of temperature detection.

[0043] The position adjustment assembly also includes a second adjustment member connected to the first adjustment member, used to adjust the position of the first adjustment member in a second direction, wherein the second direction intersects with the first direction. In this embodiment, the first direction is the vertical direction (Z-axis direction), and the second direction is the horizontal direction (X-axis direction), which are perpendicular to each other and form a planar coordinate system.

[0044] For example, the second adjusting member includes a horizontal guide rail, a horizontal drive motor, and a sliding base. The sliding base is slidably mounted on the horizontal guide rail and connected to the output end of the horizontal drive motor (e.g., via a timing belt or lead screw drive). The first adjusting member (such as the motor and lead screw shaft assembly of a lead screw mechanism) is fixedly mounted on the sliding base and moves with it in the horizontal direction.

[0045] Specifically, the horizontal guide rail is arranged horizontally along the inner wall of the distribution cabinet, and both ends are fixed to the side wall or back plate of the cabinet 200; the bottom of the sliding base is provided with a slider that matches the guide rail to ensure smooth operation; the horizontal drive motor is a stepper motor or servo motor, which has precise position control capability.

[0046] When the second adjusting component is activated, the horizontal drive motor starts, causing the sliding base to move along the horizontal guide rail, thereby changing the installation position of the first adjusting component in the X-axis direction. Since the environmental monitoring component is connected to the sliding base through the first adjusting component, its entire assembly can achieve two-dimensional movement within the XZ plane.

[0047] The control system (which can be integrated into the control panel of the distribution cabinet or a standalone controller) presets a scanning path, such as a zigzag or grid-like scanning route. During the monitoring process, the control system first moves the first adjusting component to a certain horizontal starting position via the second adjusting component, and then activates the first adjusting component to lift the environmental monitoring component from the bottom to the top of the cabinet 200, completing temperature sampling along a vertical path; subsequently, the second adjusting component moves the first adjusting component to the next horizontal position, repeating the above vertical scanning process until the key areas of the entire cabinet space are covered.

[0048] Through the aforementioned two-dimensional scanning method, the environmental monitoring component can perform multi-point sampling at different heights and horizontal positions to obtain the temperature distribution trend in the three-dimensional space inside the power distribution cabinet (although it only moves in a two-dimensional plane, it can fit a three-dimensional thermal field by combining the time dimension), effectively identifying local hot spots, ventilation blind spots, or uneven heat dissipation problems, and further reducing the risk of misjudgment caused by single-point measurement.

[0049] Compared to embodiments with only unidirectional adjustment, this implementation allows for free movement within the XZ plane, covering more monitoring points and improving data representativeness. It can avoid localized interference areas that affect sensor readings, such as cable obstructions or component blockages, allowing for the selection of the optimal monitoring position. For distribution cabinets with irregular internal structures or uneven component distribution, obstacles can be flexibly avoided by adjusting the horizontal position.

[0050] In some embodiments, the first adjusting member includes a first driving part and a pair of cross linkages 130, the middle of the pair of cross linkages 130 is hinged, the top of the pair of cross linkages 130 is connected to the first driving part, and an environmental monitoring element 140 is provided at the bottom of at least one cross linkage 130. The first driving part is used to drive the tops of the pair of cross linkages 130 to move away from or towards each other, so as to drive the bottoms of the pair of cross linkages 130 to move in a first direction.

[0051] In these embodiments, a pair of cross links 130 are arranged in an X-shape, with their intersection points hinged at the center via pins or pivots, forming a scissor-type linkage structure. The top two ends of the cross links 130 are respectively connected to the first drive unit, and at least one of the bottom ends is provided with the environmental monitoring element 140.

[0052] For example, the first drive unit includes a drive motor (e.g., a micro stepper motor or servo motor), a transmission mechanism (e.g., a gear set 170, a synchronous belt, or a push rod mechanism), and a pair of sliding seats. The drive motor is fixed to a mounting plate on the inner wall of the top of the distribution cabinet, and its output end drives the two sliding seats to move synchronously towards or away from each other along a horizontal guide rail via the transmission mechanism.

[0053] Specifically, when the drive motor rotates forward, the transmission mechanism drives the two sliding seats to move closer to each other; when rotating in reverse, they move further apart. Each sliding seat is hinged to the top end of a cross link 130, so the horizontal movement of the sliding seat is converted into the opening and closing motion of the top of the cross link 130.

[0054] The middle parts of a pair of cross linkages 130 are rotatably connected by a hinge shaft, forming a parallelogram deformation mechanism. When the first drive unit drives the tops of the two cross linkages 130 to move closer to each other, their bottoms will be forced to move downwards due to the fixed length of the linkages; conversely, when the tops move away from each other, the bottoms will separate upwards.

[0055] In this embodiment, the environmental monitoring component 140 is fixed at the bottom intersection of two cross-link portions 130, i.e., the environmental monitoring module is integrated and installed at the bottom end via a connecting plate. As the cross-link portions 130 open and close, the connecting plate moves vertically (in the first direction), thereby causing the environmental monitoring component 140 to move up and down inside the distribution cabinet, enabling temperature sampling at different heights. Simultaneously, due to the characteristics of the scissor-type linkage structure, the environmental monitoring component 140 can be moved in either the width or length direction of the distribution cabinet.

[0056] Initially, the cross linkage 130 is in a retracted state, and the environmental monitoring component 140 is located at the top of the distribution cabinet. After the control system is activated, the drive motor of the first drive unit operates, causing the sliding seats to move closer together, thus retracting the top of the cross linkage 130 and pushing the bottom-mounted environmental monitoring component 140 to slowly descend to the lower part of the cabinet 200. During this process, the temperature sensor continuously collects data. After reaching the preset position, the system can pause sampling or reverse operation to allow the monitoring component to rise again. This process can be repeated periodically to achieve "lifting" dynamic temperature measurement, effectively avoiding measurement deviations caused by hot air rising and resulting in an excessively high top temperature.

[0057] In some embodiments, the first driving unit includes: A drive shaft having a forward threaded section 120 and a reverse threaded section 150 along its axial direction, wherein the forward threaded section 120 and the reverse threaded section 150 are arranged in opposite directions; wherein the forward threaded section 120 is threadedly connected to the top of one of the cross link portions 130, and the reverse threaded section 150 is threadedly connected to the top of the other cross link portion 130. A first driving element 110 is connected to the transmission shaft. The first driving element 110 is used to drive the transmission shaft to rotate, so as to cause the tops of the pair of cross linkages 130 to move away from or closer to each other.

[0058] In these embodiments, the drive shaft is divided into two functional sections along its axial direction (e.g., the X direction): a forward thread section 120 and a reverse thread section 150, with opposite thread directions. Specifically, the forward thread section 120 is machined with a right-hand thread, and the reverse thread section 150 is machined with a left-hand thread. The lead and pitch of the two thread sections are the same to ensure motion symmetry.

[0059] The drive shaft is rotatably mounted on a mounting bracket on the top of the distribution cabinet via bearings, keeping the axis horizontal and stable.

[0060] The forward threaded section 120 is threaded to the top of one of the cross link sections 130 via a first nut-slider threaded connection; the reverse threaded section 150 is threaded to the top of the other cross link section 130 via a second nut-slider threaded connection. Each nut-slider is fixedly connected to a hinge seat at the top of a link, thereby converting rotational motion into linear motion.

[0061] When the drive shaft rotates: If rotated clockwise, the forward thread section 120 drives the first nut slider to move to the right, and the reverse thread section 150 drives the second nut slider to move to the left, causing the two to move away from each other; If rotated counterclockwise, the two will move closer to each other.

[0062] This symmetrical drive method ensures the synchronous opening and closing of the top of the pair of cross linkages 130, avoiding the mechanism from jamming or deforming due to uneven force.

[0063] For example, the first driving element 110 is a miniature DC motor or a stepper motor, whose output shaft is directly connected to one end of the transmission shaft via a coupling or gear 170 to drive the transmission shaft to rotate. The motor is fixed on a mounting bracket and electrically connected to the control panel or monitoring and control system of the power distribution cabinet via control lines.

[0064] The control system controls the motor to rotate forward, reverse, or stop according to a preset program or real-time monitoring requirements, thereby precisely adjusting the opening and closing degree of the cross linkage 130, and thus controlling the position of the environmental monitoring component 140 in the vertical direction (first direction).

[0065] For example, when the environmental monitoring component 140 needs to be lowered, the control system starts the motor to rotate counterclockwise, causing the two nut sliders to move towards each other, which in turn drives the top of the cross linkage to retract and the bottom to move down; conversely, rotating the motor clockwise will raise it back up.

[0066] To prevent the nut slider from rotating during operation, a guide rod parallel to the drive shaft is provided on the mounting bracket. Both nut sliders are simultaneously mounted on the guide rod, allowing them to slide only axially.

[0067] In some embodiments, the second adjusting member includes a second driving part and a rotating shaft 160, the second driving part and the rotating shaft 160 are connected, the rotating shaft 160 is connected to the first adjusting member, and the second driving part is used to drive the rotating shaft 160 to rotate so as to drive the first adjusting member to move along the second direction.

[0068] In these embodiments, to achieve controllable movement of the first adjusting member in a second direction (e.g., the horizontal direction), thereby expanding the spatial monitoring range of the environmental monitoring component, this application provides a second adjusting member structure based on a rotary drive-linear conversion mechanism. This structure drives the rotating shaft 160 to rotate via a second drive unit, converting the rotational motion into linear motion, which in turn drives the first adjusting member to translate along the second direction. It has the advantages of smooth transmission, accurate positioning, and compact structure.

[0069] For example, the rotating shaft 160 includes a shaft that is rotatably mounted on the inner wall of the distribution cabinet or on a mounting bracket via a bearing seat to ensure smooth rotation.

[0070] The second drive unit is a micro drive motor (such as a stepper motor or a DC geared motor), whose output shaft is connected to one end of the transmission screw shaft through a coupling or gear 170 set, and is used to drive the rotating shaft 160 to rotate.

[0071] The second drive unit is fixed to a mounting base on the side wall or base plate of the distribution cabinet, and its control signal line is connected to the central control unit or monitoring and control system of the distribution cabinet. The control system controls the second drive unit to rotate forward, reverse, or stop according to the preset scanning path or user instructions, thereby precisely adjusting the position of the first adjusting member in the horizontal direction.

[0072] In actual operation, the system can be configured with the following monitoring process: The second drive unit is activated, driving the rotating shaft to rotate 160 degrees, which in turn moves the first adjusting component to the starting position on the left side of the distribution cabinet. The first adjusting component is activated (such as the cross linkage mechanism), which drives the environmental monitoring component 140 to complete a vertical temperature sampling from top to bottom; After sampling is completed, the second drive unit moves again to move the first adjustment component to the middle position and repeats the vertical sampling. Finally, move to the right side for a third sampling.

[0073] Through the aforementioned "multi-point scanning" mode, the system can construct a spatial distribution map of the temperature inside the distribution cabinet, significantly improving the comprehensiveness and accuracy of monitoring.

[0074] In some embodiments, the second drive unit includes a second drive element 190, a gear 170 and a rack 180. The second drive element 190 and the rack 180 are connected, the gear 170 and the rack 180 mesh, and the second drive element 190 can drive the rack 180 to move so as to drive the gear 170 to rotate. The gear 170 is connected to the rotating shaft 160.

[0075] In these embodiments, to achieve reliable driving of the rotating shaft 160, this application provides a second drive unit structure based on a rack and pinion 180-gear 170 transmission mechanism. This structure drives the rack 180 to perform linear motion via a second drive element 190, which is then converted into rotational motion through gear 170 engagement, thereby driving the rotating shaft 160 to rotate and achieving translation of the first adjusting member in a second direction (e.g., horizontal direction). This solution is suitable for internal environments of distribution cabinets with limited space or requiring long-distance transmission, and has the advantages of flexible layout and rapid response.

[0076] The rack 180 is a long strip-shaped component arranged along a second direction (e.g., the X-axis direction), with straight teeth on one side. The rack 180 is slidably mounted on the inner wall of the distribution cabinet or on a special bracket via a slide rail or guide groove, ensuring that it can only move in a straight line along the axial direction.

[0077] The second drive element 190 is a miniature linear motor, an electromagnetic push rod, or a servo motor with a push rod, and its output end (push rod or piston rod) is fixedly connected to one end of the rack 180. When the second drive element 190 is activated, it pushes the rack 180 to perform reciprocating linear motion along the guide rail.

[0078] Gear 170 is a cylindrical spur gear 170 or a helical gear 170, and its teeth mesh with rack 180. Gear 170 is fixedly mounted to one end of the rotating shaft 160 by key connection or interference fit to ensure that the two rotate synchronously.

[0079] When the rack 180 moves to the left or right under the push of the second drive element 190, it drives the gear 170 to rotate clockwise or counterclockwise through meshing, thereby driving the entire rotating shaft 160 to rotate.

[0080] When the second drive element 190 pushes the rack 180 to move to the right, the gear 170 rotates counterclockwise, causing the rotating shaft 160 to drive the first adjusting member to move to the left; it should be noted that the movement path of the first adjusting member is arc-shaped.

[0081] When rack 180 moves to the left, gear 170 rotates clockwise, and the first adjusting member moves to the right.

[0082] In some embodiments, the second drive unit further includes a limiting element 182. The second drive element 190 has a fixed end and a telescopic end. The telescopic end is capable of telescopic movement relative to the fixed end. The telescopic end is connected to the rack 180. The rack 180 forms a limiting groove 181. The limiting groove 181 extends along the extension direction of the rack 180. The limiting element 182 and the limiting groove 181 are slidably engaged.

[0083] In these embodiments, to address the potential lateral swaying, torsion, or meshing misalignment of the rack 180 during the driving process, this application adds a limiting element 182 and a limiting groove 181 to the second drive unit to constrain the rack 180 to move linearly only along a preset direction. The planes containing the preset direction and the second direction are set parallel to each other, thereby improving the stability and lifespan of the transmission system.

[0084] For example, the second drive element 190 is a linear motion actuator, such as a push-pull electromagnet, an electric actuator, a miniature cylinder, or a hydraulic cylinder. It includes: Fixed end: Used for installation on the inner wall of the distribution cabinet or on the bracket, serving as the supporting foundation for the entire drive unit; Telescopic end: It is an axially telescopic push rod or piston rod, the free end of which is fixedly connected to one end of the rack 180 for transmitting driving force.

[0085] When the second drive element 190 is energized or started, the telescopic end extends or retracts, driving the rack 180 to perform linear reciprocating motion along its extension direction (i.e., the second direction).

[0086] The rack 180 is provided with a limiting groove 181 extending along its length. In this embodiment, the limiting groove 181 is a longitudinal through groove that penetrates the body of the rack 180. Its cross-section is rectangular or T-shaped and it is located on the non-tooth side or back of the rack 180 to avoid affecting the meshing of the gear 170.

[0087] The limiting element 182 is a rigid pin, guide post, or slider, one end of which is fixed to the mounting bracket of the distribution cabinet, and the other end is inserted into the limiting groove 181 and slides against the groove wall. The axis of the limiting element 182 is parallel to the second direction, ensuring that it only allows the rack 180 to slide along the length of the groove.

[0088] When the rack 180 moves under the push of the second drive element 190, the limiting element 182 slides synchronously in the limiting groove 181, which serves the following functions: To prevent lateral deviation: constrain the rack 180 degrees to prevent it from moving left or right (perpendicular to the direction of movement); Suppressing torsion: Preventing rack 180 from rotating around its own axis, which could lead to poor meshing of gear 170; Improve guiding accuracy: Auxiliary slide rails or guide grooves form multi-point support and enhance overall rigidity.

[0089] For example, the limiting groove 181 can also be designed as a dovetail groove, a U-shaped groove or an array of circular holes to match the limiting elements 182 of different shapes.

[0090] Multiple limiting elements 182 can be provided and distributed along the length of the rack 180 to further improve the guiding stiffness; In high-precision applications, the limit element 182 can be made of ball bushing or linear bearing to reduce frictional resistance.

[0091] In some embodiments, the first direction and the second direction are arranged perpendicularly.

[0092] In some embodiments, this application also provides a power distribution switch cabinet, which includes a cabinet body 200 and a monitoring mechanism 100 as described in any of the above embodiments. The height direction of the cabinet body 200 is parallel to the first direction, and the movement range of the environmental monitoring device is located within the cabinet body 200.

[0093] Since the monitoring device 100 has the aforementioned technical effects, the power distribution switchgear including the monitoring device 100 should have the same technical effects, which will not be elaborated here.

[0094] In some embodiments, the cross-section of the cabinet 200 is arranged parallel to the second direction.

[0095] To maximize the use of the internal space of the power distribution switchgear and ensure that the environmental monitoring components can efficiently and accurately monitor the temperature in different areas within the cabinet, this application proposes a preferred design: the cross-sectional shape of the power distribution switchgear is arranged parallel to a second direction (such as the horizontal direction, the X-axis direction, or the Y-axis direction). This means that the design of the power distribution cabinet takes into account the horizontal movement requirements of the monitoring mechanism 100, thereby achieving a more reasonable and efficient internal layout.

[0096] Assuming the power distribution switchgear has a rectangular or square cross-section, where: Width direction (X-axis direction): corresponds to the second direction; Depth direction (Y-axis direction): Perpendicular to the second direction but on the same horizontal plane; Height direction (Z-axis direction): Corresponds to the first direction, used by the first adjustment component to drive the environmental monitoring component to move up and down.

[0097] In this layout, the second adjusting member drives the first adjusting member to move along the width direction (X-axis), allowing the environmental monitoring components to cover the entire width range from left to right in the front view of the distribution cabinet. This design not only simplifies the design of the mechanical structure but also facilitates electrical wiring and maintenance.

[0098] Since the second direction is consistent with the 200mm width of the cabinet, the control system can more easily plan the monitoring path, such as using the "line-by-line scanning" mode, moving from one side to the other in sequence to ensure that every corner can be effectively monitored; Setting the second direction parallel to the 200mm width of the cabinet reduces the risk of collision with other internal components (such as cable trays, cooling fans, etc.) and helps to keep the inside of the equipment clean and orderly. This layout allows the monitoring system to complete a full scan with the shortest path, reducing unnecessary travel distances and improving work efficiency; For distribution cabinets of different specifications, the travel of the second adjusting component can be adjusted to accommodate various width dimensions, demonstrating good versatility and expandability.
