Description

Technical Field

[0001] This utility model relates to the field of power distribution room technology, and more specifically, it relates to an environmental monitoring device for power distribution rooms. Background Technology

[0002] In modern power systems, the power distribution room is a key node for power distribution and conversion. Its safe and stable operation directly affects the reliability of the entire power supply network and the continuity of enterprise production, which places strict requirements on the ease of maintenance of environmental monitoring devices.

[0003] Traditional monitoring devices mostly adopt a fixed installation method, with the monitoring head and the bracket being fixed by complex bolts or welding. When the equipment needs to be routinely inspected, cleaned or the sensing element replaced, maintenance personnel often need to carry a variety of special tools and spend a lot of time disassembling the fasteners one by one. In high-density equipment environments, the operating space is limited, which reduces the overall reliability of the monitoring system and cannot meet the core requirements of the power system for high availability and rapid response of the equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides an environmental monitoring device for power distribution rooms to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmental monitoring device for a power distribution room, comprising a fixed frame and a monitoring head. An adjustment mechanism is provided on the fixed frame, the adjustment mechanism including clamping blocks and a universal ball joint. Two sets of clamping blocks are disposed on the outer wall of the fixed frame, and the universal ball joint is disposed inside the two sets of clamping blocks. A quick-release mechanism is provided between the universal ball joint and the monitoring head. The quick-release mechanism includes a fixed sleeve and a plug rod. The fixed sleeve is fixed to the side of the universal ball joint, and the plug rod is fixed to the bottom end of the monitoring head. A slider is slidably provided on the outer wall of the fixed sleeve. Multiple sets of sliders are provided, each with a locking block fixed at its bottom. A locking groove is opened on the outer wall of the plug rod. Push blocks are fixedly provided at the top of each set of sliders. A movable groove is opened on the outer wall of the fixed sleeve. Multiple sets of movable grooves are provided and slidably connected to multiple sets of push blocks.

[0008] The present invention is further configured such that a limiting mechanism is provided on the outer side of the fixed sleeve, the limiting mechanism including a limiting sleeve and a rotating sleeve, the rotating sleeve sliding on the outer wall of the fixed sleeve, the rotating sleeve being rotatably mounted on the outer wall of the fixed sleeve, a limiting groove being formed on the outer wall of the limiting sleeve, and a support rod being fixedly provided on the outer wall of the rotating sleeve. Multiple sets of support rods are respectively fixed on the outer wall of the rotating sleeve, and a limiting block is fixedly provided on the inner wall of each set of support rods. Multiple sets of limiting blocks are provided and slide in the limiting grooves respectively. This design constructs a dual locking protection system. By rotating the rotating sleeve to drive the limiting blocks to slide in the limiting grooves, the locking and unlocking states are switched. Multiple sets of support rods and limiting blocks disperse the stress points and enhance the structural stability, effectively preventing the monitoring head from accidentally falling off in a vibration environment.

[0009] The present invention is further configured such that an adjustment groove is provided on the inner side of each of the multiple sets of clamping blocks, the universal ball slides in the adjustment groove, and the multiple sets of clamping blocks are connected by bolts. The adjustment groove design provides sufficient space for the universal ball to move, enabling the monitoring head to be freely adjusted in three dimensions. The bolt connection method allows for precise control of the clamping force, ensuring stable fixation after angle adjustment, simplifying the operation process and improving the adjustment accuracy.

[0010] The present invention is further configured such that a sliding hole is provided inside the insertion rod, a compression spring is connected inside the sliding hole, and a top block is connected to the top of the compression spring. The top block slides inside the sliding hole. The elastic pop-out mechanism ensures the convenience of disassembly operation. When the locking is released, the compression spring releases potential energy to automatically push the insertion rod out of the fixing sleeve. No additional pulling tools are required, which reduces the intensity of manual operation and improves maintenance efficiency and safety.

[0011] The present invention is further configured such that a push spring is provided between the inner wall of the multiple sets of push blocks and the movable groove. The push spring design provides a continuous restoring force, ensuring that the block can quickly disengage from the groove after unlocking, forming an automatic unlocking function, reducing the risk of jamming, ensuring the smoothness and reliability of the disassembly process, and effectively extending the service life of the connecting parts.

[0012] The present invention is further configured such that the outer wall of the limiting sleeve is provided with an unlocking groove, and multiple sets of unlocking grooves are provided. The design of multiple sets of unlocking grooves provides a clear unlocking position, so that the limiting block can completely exit the limiting state at a specific position, forming a mechanical safety interlocking mechanism, preventing partial unlocking state caused by misoperation, and ensuring the integrity and safety of the unlocking process.

[0013] The present invention is further configured such that the outer walls of the multiple sets of push blocks are all set as inclined surfaces, and the inner side of the limiting sleeve is provided with rounded corners. The combination design of the inclined surfaces and rounded corners reduces the contact resistance between the push blocks and the limiting sleeves, allowing the limiting sleeves to smoothly slide over the push blocks for locking or unlocking, reducing the operating torque requirement, improving the operating experience, and at the same time avoiding edge wear and extending the service life of the components.

[0014] The present invention is further configured such that a sliding groove is provided on the inner side of the rotating sleeve, and multiple sets of the sliding groove are provided, each of which has a positioning block slidingly mounted inside. Each of the multiple sets of positioning blocks and the inner side of the sliding groove is provided with a compression spring. A positioning groove is provided on the outer wall of the fixed sleeve, and multiple sets of the positioning groove are provided, each of which is arc-shaped and abuts against the multiple sets of positioning blocks. The elastic positioning system provides precise positioning and feedback of the rotation position of the rotating sleeve. When the rotating sleeve rotates to the locked or unlocked position, the positioning block will be engaged in the corresponding positioning groove to generate obvious tactile feedback. The arc-shaped design increases the contact area and reduces local stress, and the compression spring ensures contact reliability, forming an intuitive operation status indication.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an environmental monitoring device for power distribution rooms, which has the following beneficial effects:

[0017] 1. The adjustment mechanism adopts a combination design of clamping blocks and a universal ball joint to achieve all-round adjustment of the monitoring head angle. The clamping blocks are symmetrically set on the outer wall of the fixed frame to form a reliable support structure. The universal ball joint adopts a spherical structure with three-dimensional rotational freedom. The design of the adjustment groove provides the universal ball joint with room for movement to ensure adjustment flexibility. The bolt connection method realizes a simple and reliable locking function. The controllable clamping force ensures stable fixation after angle adjustment. The spherical contact increases the friction area and improves positioning accuracy. This design completely solves the problem of poor adaptability of traditional fixed angle monitoring devices, enabling the monitoring head to flexibly adjust the monitoring angle according to the layout of the power distribution room equipment and monitoring needs, significantly improving the accuracy and comprehensiveness of environmental data acquisition.

[0018] 2. The quick-installation mechanism enables rapid installation and removal of the monitoring head through the plug-in connection of the fixing sleeve and the plug rod. The fixing sleeve is firmly installed on the surface of the universal ball as the connection base, and the plug rod is fixed to the bottom of the monitoring head to form a docking component. The combination design of the slider and the locking block enhances the connection stability through lateral locking. The precise fit between the locking slot and the locking block ensures the reliability of the connection. The sliding connection design of the push block and the movable slot enables smooth guidance during the installation and removal process. The elastic reset system of the compression spring and the top block facilitates automatic pop-out during disassembly. The push spring provides continuous restoring force, giving the locking system a self-locking function. The inclined push block design reduces operating resistance and improves the smoothness of operation. This quick-installation mechanism can complete the installation and removal of the monitoring head without tools, which greatly improves the equipment maintenance efficiency and response speed and reduces the downtime of the power distribution room.

[0019] 3. The limiting mechanism provides a second layer of safety for the quick-assembly mechanism through the combination design of the limiting sleeve and the rotating sleeve. The limiting sleeve is fitted outside the fixed sleeve to form a protective barrier, and the rotating sleeve adopts a rotation locking method to simplify the operation steps. The linkage design of the support rod and the limiting block transforms the rotational motion into a locking function. The dual-position design of the limiting groove and the unlocking groove realizes a clear locking and unlocking state. The rounded corner design of the inner side of the limiting sleeve reduces the frictional resistance when in contact with the push block. The elastic positioning system of the slide and the positioning block provides accurate feedback on the rotational position. The compression spring ensures reliable contact between the positioning block and the positioning groove. The arc-shaped positioning structure increases the contact area and disperses stress. This limiting mechanism constructs a complete anti-loosening protection system, effectively preventing the monitoring head from accidentally falling off in a vibration environment, while maintaining ease of operation, and further improving the safety and reliability of the monitoring system.

[0029] Please see Figures 1-5 An environmental monitoring device for a power distribution room includes a fixed frame 1 and a monitoring head 2. The fixed frame 1 is provided with an adjustment mechanism, which includes clamping blocks 3 and universal balls 4. Two sets of clamping blocks 3 are provided on the outer wall of the fixed frame 1, and the universal balls 4 are provided on the inner side of the two sets of clamping blocks 3. A quick-installation mechanism is provided between the universal balls 4 and the monitoring head 2. The quick-installation mechanism includes a fixed sleeve 5 and a plug rod 6. The fixed sleeve 5 is fixed to the outer side of the universal balls 4, and the plug rod 6 is fixed to the bottom end of the monitoring head 2. A slider 7 is slidably provided on the outer wall of the fixed sleeve 5. Multiple sets of sliders 7 are provided, and each of them has a locking block 8 fixed at its bottom end. A locking groove 9 is opened on the outer wall of the plug rod 6. Push blocks 10 are fixed at the top of each of the multiple sets of sliders 7. An movable groove 11 is opened on the outer wall of the fixed sleeve 5. Multiple sets of movable grooves 11 are provided and are slidably connected to multiple sets of push blocks 10 respectively.

[0030] A limiting mechanism is provided on the outer side of the fixed sleeve 5. The limiting mechanism includes a limiting sleeve 12 and a rotating sleeve 13. The rotating sleeve 13 slides on the outer wall of the fixed sleeve 5 and is rotatably mounted on the outer wall of the fixed sleeve 5. A limiting groove 14 is opened on the outer wall of the limiting sleeve 12. A support rod 15 is fixedly provided on the outer wall of the rotating sleeve 13. Multiple sets of support rods 15 are respectively fixed on the outer wall of the rotating sleeve 13. A limiting block 16 is fixedly provided on the inner wall of each set of support rods 15. Multiple sets of limiting blocks 16 are provided and slide in the limiting groove 14 respectively. This structure works based on the principle of rotation locking. When the rotating sleeve 13 rotates, the support rod 15 is moved through the linkage mechanism, causing the limiting block 16 to slide in the limiting groove 14, forming a mechanical interference lock. The multiple sets of designs disperse the force and enhance the structural stability, providing a reliable secondary locking guarantee for the quick-assembly mechanism.

[0031] Multiple clamping blocks 3 are provided with adjustment grooves 17 on their inner sides. The universal ball 4 slides in the adjustment grooves 17. The multiple clamping blocks 3 are connected by bolts. This structure is based on the principle of spherical joint. It utilizes the spherical geometry of the universal ball 4 to achieve free rotation in three-dimensional space. The adjustment grooves 17 provide the universal ball 4 with room to move. The bolt connection adopts the principle of thread engagement. By adjusting the axial pressure, the friction force of the clamping block 3 on the universal ball 4 is controlled to achieve the balance between angle adjustment and fixation, ensuring the precise adjustment and stable maintenance of the position of the monitoring head 2.

[0032] The insertion rod 6 has a sliding hole 18 inside, and a compression spring 19 is connected inside the sliding hole 18. A top block 20 is connected to the top of the compression spring 19. The top block 20 slides inside the sliding hole 18. This mechanism is based on the principle of elastic potential energy storage and release. When inserted, the top block 20 is compressed by the compression spring 19 to store elastic potential energy. After unlocking, the potential energy is released, pushing the top block 20 to drive the insertion rod 6 to pop out. The sliding hole 18 provides axial guidance for the top block 20, ensuring that the direction of force transmission is consistent, forming an automatic pop-out mechanism that simplifies the disassembly operation.

[0033] A push spring 21 is provided between the inner wall of the multiple push blocks 10 and the movable groove 11. This design is based on the spring reset principle. The push spring 21 stores elastic potential energy in the compressed state. When the limiting sleeve 12 moves away and releases the contact with the push block 10, the push spring 21 releases energy to push the push block 10 to slide along the movable groove 11, thereby driving the slider 7 and the locking block 8 to disengage from the locking groove 9, realizing the automatic unlocking function and eliminating the need for manual pulling.

[0034] The outer wall of the limiting sleeve 12 is provided with an unlocking groove 22. There are multiple sets of unlocking grooves 22. This structure is based on the principle of mechanical interlock. The unlocking groove 22 and the limiting groove 14 form an alternating groove system. When the rotating sleeve 13 rotates to a specific angle, the limiting block 16 enters the unlocking groove 22 from the limiting groove 14, releasing the lock on the limiting sleeve 12. This forms a clear two-position state transition mechanism and prevents instability in the intermediate state.

[0035] The outer walls of multiple push blocks 10 are all set as inclined surfaces, and the inner side of the limiting sleeve 12 is provided with rounded corners. This design is based on the principle of contact geometry. The inclined surface structure decomposes the force exerted by the limiting sleeve 12 on the push block 10 into radial and axial components, reducing radial resistance. The rounded corner design reduces the concentration of contact stress. The combination of the two reduces frictional resistance and wear, and improves the smoothness of operation and the durability of the components.

[0036] The inner side of the rotating sleeve 13 is provided with a sliding groove 23. Multiple sets of sliding grooves 23 are provided, and each set of positioning blocks 24 are slidably provided inside. Compression springs 25 are provided on the inner side of the multiple sets of positioning blocks 24 and sliding grooves 23. The outer wall of the fixed sleeve 5 is provided with a positioning groove 26. Multiple sets of positioning grooves 26 are provided, and each set of positioning blocks 24 is arc-shaped and abuts against each other. This mechanism is based on the principle of elastic positioning. When the rotating sleeve 13 rotates, the positioning blocks 24 compress the compression springs 25 and temporarily disengage from the positioning grooves 26. After rotating to the preset position, the positioning blocks 24 are re-embedded into the new positioning grooves 26 under the action of elasticity, generating tactile and auditory feedback. The arc design increases the contact area and guides the positioning blocks 24 to accurately enter the groove, forming a precise position sensing system.

[0037] In this embodiment, when the monitoring head 2 needs to be installed, the insertion rod 6 is inserted into the fixed sleeve 5 and the compression spring 19 is compressed by the top block 20, pushing the limiting sleeve 12 to abut against the outer wall of the multiple sets of push blocks 10 so that it slides along the movable groove 11 and compresses the push spring 21. At the same time, the multiple sets of sliders 7 push the locking block 8 to engage in the locking groove 9, locking the insertion rod 6. At this time, the multiple sets of limiting blocks 16 are in the unlocking groove 22. Rotating the rotating sleeve 13 drives the multiple sets of support rods 15 to rotate and drives the multiple sets of limiting sleeves 12 to slide into the limiting groove 14 to support and fix the limiting sleeves 12. When the rotating sleeve 13 rotates, the multiple sets of positioning grooves 26 push the positioning block 24 to slide along the sliding groove and compress the compression spring 25, so that the multiple sets of positioning When block 24 moves within positioning groove 26, and rotating sleeve 13 stops rotating, multiple sets of compression springs 25 reset and push positioning block 24 to abut within positioning groove 26 to fix rotating sleeve 13. When it is necessary to disassemble monitoring head 2, rotating rotating sleeve 13 drives multiple sets of support rods 15 to rotate, causing multiple sets of limit blocks 16 to disengage from limit groove 14 and move into unlocking groove 22, releasing the support and fixation of limit sleeve 12, pushing limit sleeve 12 to release abutment of multiple sets of push blocks 10, pushing push blocks 10 through multiple sets of push springs 21, and pulling block 8 out of slot 9 through slider 7, releasing insertion of insertion rod 6, and resetting positioning block 24 through compression spring 19 to make insertion rod 6 pop out of fixing sleeve 5, thereby completing the disassembly of monitoring head 2.

[0038] More specifically, when the angle of the monitoring head 2 needs to be adjusted, the bolts between the multiple sets of clamping blocks 3 are turned to release the clamping blocks 3 from the universal ball 4, allowing the universal ball 4 to slide within the adjustment groove 17. The angle of the monitoring head 2 is adjusted by the universal ball 4. Then, the multiple sets of bolts are tightened to engage with the clamping blocks 3, so that the clamping blocks 3 are clamped on the outer wall of the universal ball 4 to fix the monitoring head 2, thus completing the angle adjustment of the monitoring head 2.

[0039] In summary, during the use or operation of the overall equipment: when the monitoring head 2 needs to be installed, the insertion rod 6 is inserted into the fixed sleeve 5, and the compression spring 19 is compressed by the top block 20, pushing the limiting sleeve 12 against the outer wall of the multiple sets of push blocks 10, causing it to slide along the movable groove 11 and compress the push spring 21. At the same time, the multiple sets of sliders 7 push the locking block 8 into the locking groove 9, locking the insertion rod 6. At this time, the multiple sets of limiting blocks 16 are in the unlocking groove 22. Rotating the rotating sleeve 13 drives the multiple sets of support rods 15 to rotate and drives the multiple sets of limiting sleeves 12 to slide into the limiting groove 14 to support and fix the limiting sleeves 12. When the rotating sleeve 13 rotates, the positioning block 24 is pushed along the sliding groove 26 through the multiple sets of positioning grooves 26 and compresses the compression spring 25, so that... Multiple sets of positioning blocks 24 move within the positioning groove 26. When the rotating sleeve 13 stops rotating, multiple sets of compression springs 25 reset and push the positioning blocks 24 to abut against the positioning groove 26 to fix the rotating sleeve 13. When it is necessary to disassemble the monitoring head 2, rotating the rotating sleeve 13 drives multiple sets of support rods 15 to rotate, causing multiple sets of limit blocks 16 to disengage from the limit groove 14 and move into the unlocking groove 22, releasing the support and fixation of the limit sleeve 12. Pushing the limit sleeve 12 releases the abutment of multiple sets of push blocks 10. Multiple sets of push springs 21 push the push blocks 10 and the slider 7 pulls the locking block 8 to disengage from the locking groove 9, releasing the insertion of the insertion rod 6. The compression spring 19 resets and pushes the positioning block 24, causing the insertion rod 6 to pop out of the fixing sleeve 5, thereby completing the disassembly of the monitoring head 2.

[0040] When the angle of the monitoring head 2 needs to be adjusted, the bolts between the multiple sets of clamping blocks 3 are turned to release the clamping blocks 3 from the universal ball 4, allowing the universal ball 4 to slide in the adjustment groove 17. The angle of the monitoring head 2 is adjusted by the universal ball 4. Then, the multiple sets of bolts are tightened to engage with the clamping blocks 3, so that the clamping blocks 3 are clamped on the outer wall of the universal ball 4 to fix the monitoring head 2, thus completing the angle adjustment of the monitoring head 2.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other well-known connection methods. They will not be elaborated here. For all the fixed connections mentioned above, welding is the preferred option.

[0042] In all the solutions mentioned above, those involving the operation of electrical components, unless otherwise specified, are controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and circuit connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here.

[0043] Of all the solutions mentioned above, those involving motors can be combined with reducers if necessary. The connection structure and working principle between the motor and the reducer are existing known technologies and will not be addressed in this utility model.
