Description

Technical Field

[0001] This utility model relates to the field of engineering safety monitoring and management, and in particular to an engineering safety monitoring hub. Background Technology

[0002] As engineering construction scales expand and construction risks increase, the need for real-time monitoring of safety status becomes increasingly urgent. This has highlighted the importance of engineering safety monitoring hubs as the core of data transmission. Initially, monitoring data relied on manual copying or transmission via simple signal converters, which were susceptible to environmental interference leading to data loss. Furthermore, these hubs were only compatible with a limited number of sensors, making management difficult and inefficient, and failing to meet safety monitoring needs. Technological advancements have driven hub upgrades. In later stages, the application of metal casings and anti-interference components, multi-protocol interfaces for various sensors, and the addition of local caching functions have significantly improved data integrity. The structure has also been optimized, with modular designs allowing for the addition of GPS and alarm modules, enabling targeted adaptation to scenarios such as bridges and foundation pits. Today's more feature-rich hubs can connect to cloud platforms. From a safety engineering technical consulting perspective, they not only improve monitoring accuracy and facilitate risk early warning but also reduce manual labor costs, becoming key equipment for engineering safety management.

[0003] Engineering safety monitoring hubs primarily utilize modular components and scenario-adaptive design to achieve accurate data acquisition and secure transmission of engineering monitoring data. Equipped with multiple interface components and employing a hierarchical data processing mode, these hubs filter and target abnormal data for different monitoring dimensions and transmission frequencies, preventing data loss and transmission delays. This prevents missed engineering risks and equipment damage due to monitoring failures. Some intelligent hubs can be combined with threshold warning modules and remote control units to adjust data sampling intervals and fault response speeds. The overall design balances anti-interference performance with ease of maintenance. Small hubs are suitable for the distributed monitoring needs of small to medium-sized projects, while large hubs rely on cloud-based monitoring platforms for large-scale data management, ensuring high reliability of engineering monitoring. This creates a real-time, low-error monitoring environment for engineering safety management, facilitating the safe and efficient advancement of engineering construction. It is a core monitoring device recommended in safety engineering technical consulting.

[0004] Current engineering safety monitoring hubs have significant shortcomings. They lack flexibility in on-site deployment and use, lack dedicated cable management structures, and expose various monitoring cables, relying solely on simple bundling for fixation. These cables are easily damaged during construction, and the messy cables increase the difficulty of troubleshooting and affect the stability of monitoring data transmission. Furthermore, hubs are mostly designed for fixed installations and cannot rotate in multiple directions. Faced with complex monitoring angle requirements on engineering sites, they cannot flexibly adjust the device's orientation to accommodate the wiring and data acquisition of sensors in different locations, resulting in blind spots in some monitoring areas and reducing monitoring coverage and accuracy. These problems not only increase equipment maintenance costs but may also lead to engineering safety hazards due to monitoring failures. Therefore, structural optimization is needed to address these issues. This paper proposes an engineering safety monitoring hub to solve these problems. Utility Model Content

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1 to 3 This utility model provides an embodiment of an engineering safety monitoring hub, including a hub housing 1. The hub housing 1 serves as the external protective structure of the hub, which can isolate external dust, moisture and other impurities, and protect the internal monitoring components to ensure stable operation. An automatic switch mechanism 2 is fixedly connected to the bottom of the hub housing 1. The automatic switch mechanism 2 realizes the automatic opening and closing of the drawer through mechanical transmission, which facilitates the operator to inspect or connect the internal components of the hub. A support mechanism 3 is installed at the bottom of the automatic switch mechanism 2. The support mechanism 3 provides a supporting foundation for the entire hub and can flexibly adjust the placement of the hub to adapt to the installation requirements of different engineering monitoring scenarios. The automatic switch mechanism 2 includes a drawer housing 21, which provides installation and protection space to prevent transmission components from being interfered with by external factors. The top of the drawer housing 21 is fixedly connected to the bottom of the hub housing 1, so that the drawer housing 21 and the hub housing 1 form a stable whole, ensuring the stability of the automatic switch mechanism 2 during operation. The inner wall of the drawer housing 21 is slidably connected to a drawer liner 22, which can store the hub's connection wires or auxiliary components. It can be opened and closed by sliding, making it convenient to access the internal items. The inner wall of the drawer housing 21 is fixedly connected to a fixed frame 23, which provides installation support and ensures that each component moves along a predetermined trajectory. The outer wall of the fixed frame 23 is rotatably connected to a moving strip 24, which assists in the automatic pop-out action of the drawer by rotating and sliding. One end of the moving strip 24 is slidably connected to a moving block 25, which can slide within the fixed frame 23 to lock and unlock the drawer liner 22. A movable column 26 is fixedly connected to the inner wall of the movable block 25. The movable column 26 directly contacts the inner drawer liner 22 and drives the movable block 25 to slide through the pushing force of the inner drawer liner 22. It is a key component of the transmission. A spring 27 is sleeved on the outer wall of the movable column 26. The spring 27 stores or releases elastic force by utilizing elastic deformation to provide power for the reset of the movable block 25 and the movable column 26, realizing the automatic pop-out of the drawer. Two fixed columns 28 are fixedly connected to the outer wall of the fixed frame 23. The fixed columns 28 provide a pivot point to ensure that the hooking and disengaging actions can be completed stably. An auxiliary component 29 is fixedly connected to the bottom end of the movable block 25. The auxiliary component 29 locks the inner drawer liner 22 to ensure the stability of the drawer when it is closed. The auxiliary component 29 includes two fixed blocks 291. The two fixed blocks 291 provide installation support to ensure synchronous movement. The outer walls of the two fixed blocks 291 are fixedly connected to the outer wall of the movable block 25, so that the fixed blocks 291 and the movable block 25 are firmly connected, ensuring that the auxiliary component 29 can be driven to move synchronously when the movable block 25 slides. Two fixed blocks 291 are slidably connected to the inner walls of a rotating bar 292. The rotating bar 292 can move with the fixed blocks 291 and rotate simultaneously to achieve engagement or disengagement. The outer wall of the rotating bar 292 is fixedly connected to a hook 293. The hook 293 can be engaged or disengaged by rotation to directly lock and unlock the drawer liner 22. The bottom end of the drawer liner 22 is fixedly connected to a fixed plate 294. The fixed plate 294 cooperates with the hook 293 to provide a locking point for the drawer liner 22, ensuring that the drawer will not slide on its own after it is closed. One end of the spring 27 is fixedly connected to the inner wall of the fixed frame 23. The fixed frame 23 provides fixed support for the spring 27 to ensure that the spring 27 can stably store its elastic force. The other end of the spring 27 is fixedly connected to the outer wall of the moving block 25, so that the elastic force of the spring 27 can directly act on the moving block 25 to push the moving block 25 to reset. The outer wall of the movable block 25 is slidably connected to the inner wall of the fixed frame 23. The fixed frame 23 guides the sliding of the movable block 25 and prevents it from shifting during movement. The outer wall of the hook 293 is rotatably connected to the outer walls of the two fixed posts 28. The fixed posts 28 restrict the rotation trajectory of the hook 293, ensuring that the hook 293 can accurately hook the fixed plate 294. The outer wall of the movable post 26 is slidably connected to the inner wall of the fixed frame 23. The fixed frame 23 provides guidance for the sliding of the movable post 26, ensuring that the movable post 26 can smoothly drive the movable block 25 to move. The hook 29... The outer wall of the drawer liner 22 is in contact with the outer wall of the fixing plate 294. The contact between the hook 293 and the fixing plate 294 locks the drawer liner 22, preventing the drawer from opening by itself. The outer wall of the hook 293 is rotatably connected to one side of the two fixing blocks 291. The fixing blocks 291 provide additional rotational support for the hook 293, making the hook 293 rotate more smoothly. The outer wall of the moving column 26 is in contact with the outer wall of the drawer liner 22. The contact between the moving column 26 and the drawer liner 22 ensures that the pushing force of the drawer liner 22 can be directly transmitted to the moving column 26, driving the transmission components to move.

[0024] like Figure 1 and Figure 4 As shown, the support mechanism 3 includes a base plate 31, which provides an installation base for other components of the support mechanism 3 and increases the contact area with the placement surface, thereby improving the placement stability of the hub. The outer wall of the base plate 31 is fixedly connected to the bottom end of the automatic switch mechanism 2, so that the base plate 31 and the automatic switch mechanism 2 are firmly connected, ensuring the stable support of the hub by the support mechanism 3. An upper rotating column 32 is fixedly connected to the outer wall of the base plate 31, which provides a rotation fulcrum. A fixed plate 33 is rotatably connected to the outer wall of the upper rotating column 32, which is connected to the upper rotating column 32 to transmit the rotation action and realize the orientation adjustment of the hub. A connecting arm 34 is fixedly connected to the outer wall of the fixed disk 33. The connecting arm 34 connects to the fixed disk 33, enabling the rotation of the upper rotating column 32 to work in tandem. A lower rotating column 35 is fixedly connected to one end of the connecting arm 34. The lower rotating column 35 provides a fulcrum for rotation, allowing the connecting arm 34 to drive the hub to revolve. A bottom column 36 is rotatably connected to the outer wall of the lower rotating column 35. The bottom column 36 provides bottom support for the entire support mechanism 3, ensuring the overall stability of the support mechanism 3. The lower rotating column 35 has a circular cross-section, which allows the lower rotating column 35 to rotate flexibly around the bottom column 36, reducing rotational resistance. The connecting arm 34 has a rectangular cross-section, which enhances the structural strength of the connecting arm 34 and prevents the connecting arm 34 from deforming during the support process.

[0025] Working principle: When the drawer needs to be closed, an external force pushes the drawer liner 22 inward. This pushes the moving column 26 backward. The force of the drawer liner 22 is transmitted through contact with the moving column 26, driving it to slide backward and providing power for the subsequent locking action. Because the moving column 26, moving block 25, and fixed block 291 are fixedly connected, the movement of the moving column 26 will cause the fixed block 291 to move. The sliding of the moving column 26 is synchronously transmitted to the moving block 25 and fixed block 291 through the fixed connection, ensuring coordinated movement of all components. Since the hook 293 is rotatably connected to the outer wall of the fixed block 291, the movement of the fixed block 291 will cause the hook 293 to rotate. The movement of the fixed block 291 causes the hook 293 to rotate around the fixed column 28, adjusting the angle of the hook 293. Therefore, the hook 293 hooks onto the fixed plate 294. After rotation, the hook 293 precisely engages with the fixed plate 294, locking the drawer liner 22 and thus achieving the purpose of closing the drawer. Ensure the drawer is securely closed and will not slide on its own. When the drawer needs to be opened, press the drawer liner 22 inward. The moving column 26 will continue to move inward. Press the drawer liner 22 again to make the moving column 26 slide further, triggering the unlocking action. At this time, the hook 293 will release the restriction on the fixing plate 294. The hook 293 continues to rotate with the sliding of the moving column 26, disengaging from the hooked state with the fixing plate 294, completing the unlocking. One end of the moving bar 24 will slide in the groove of the moving block 25. The sliding of the moving bar 24 assists in adjusting the position of the moving block 25, preparing for the spring 27 to release its elastic force. The spring 27 releases its elastic force to push the moving block 25 and the moving column 26 outward. The elastic force stored in the spring 27 is quickly released, pushing the moving block 25 and the moving column 26 to slide outward. At this time, the drawer liner 22 will pop out. The sliding of the moving column 26 pushes the drawer liner 22 outward, realizing the automatic opening of the drawer, thereby achieving the purpose of opening the drawer, making it convenient for operators to quickly retrieve items or repair parts inside the drawer. When the orientation of the hub housing 1 needs to be adjusted, because the lower rotating column 35 is rotatably connected to the bottom column 36, and the upper rotating column 32 is rotatably connected to the fixed plate 33, and the connecting arm 34 connects the lower rotating column 35 and the fixed plate 33, the rotation of the lower rotating column 35 around the bottom column 36 drives the connecting arm 34 and the fixed plate 33 to revolve, and the rotation of the upper rotating column 32 around the fixed plate 33 drives the hub housing 1 to rotate. The two work together to achieve multi-directional orientation adjustment, so that the hub housing 1 can both revolve and rotate. The revolve adjusts the overall placement direction of the hub, and the rotation adjusts the front orientation of the hub, meeting the wiring and observation requirements of different monitoring scenarios, thereby achieving the purpose of orientation adjustment, ensuring that the hub can adapt to the installation position of the engineering site, and improving the convenience of monitoring operation.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
