Description

Technical Field

[0001] This utility model relates to the field of fire monitoring equipment technology, specifically a fire monitoring device for an energy storage photovoltaic power station. Background Technology

[0002] A photovoltaic power station with energy storage is a type of power station that combines photovoltaic power generation and energy storage technologies. Photovoltaic power generation uses solar photovoltaic panels to convert solar energy into electrical energy, while energy storage technology can store excess electrical energy and release it for power supply when needed. Fire monitoring equipment is used to monitor fires and fire risks in photovoltaic power stations with energy storage. These devices typically include fire alarm systems, smoke detectors, fire monitoring cameras, temperature monitors, flame detectors, etc.

[0003] The utility model patent application with publication number "CN221704957U" discloses a fire monitoring device for an energy storage photovoltaic power station, mainly composed of a support column, a mounting plate, and a bottom plate. This technical solution utilizes snap-fit ​​pieces and snap-fit ​​blocks for snap-fit, followed by locking with a stop bar and then locking with a pin and locking block. This allows for convenient disassembly and maintenance of the monitoring components without the need to find tools to tighten bolts, thus providing convenience. By using pull rope one and pull rope two to fix the pole with fasteners and then adjusting the tension with adjusting components and a rotating cylinder, the stability of the fire monitoring device after installation is increased, preventing tilting during use.

[0004] The fire monitoring equipment for energy storage photovoltaic power stations disclosed in the aforementioned document has the following defects: the monitoring components of the fire monitoring equipment are rigidly fixed to the bottom plate with bolts, and the bottom plate is locked in the mounting groove of the horizontal mounting plate by the cooperation of the snap-fit ​​blocks and snap-fit ​​pieces. The entire mounting plate is also rigidly connected to the support column. This will result in the orientation and pitch angle of the monitoring components being completely fixed during installation and unable to be adjusted in any way. Once the installation is completed, the field of view of the monitoring equipment cannot be changed. In practical applications, the site of the energy storage power station may have complex terrain or obstacles, and the monitoring needs may also change over time (such as the addition of equipment blocking the field of view). The fixed viewing angle will result in the monitoring blind spots not being eliminated, which greatly reduces the flexibility and adaptability of the system. Utility Model Content

[0005] The purpose of this utility model is to provide a fire prevention monitoring device for energy storage photovoltaic power stations, which solves the problem that existing fire prevention monitoring devices cannot flexibly adjust the orientation and pitch angle of the monitoring components during use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a fire prevention monitoring device for an energy storage photovoltaic power station, comprising a fixed base plate, a support column fixedly connected to the upper end of the fixed base plate, an adjustment structure provided at the upper end of the support column, an mounting plate provided at the upper end of the adjustment structure, a monitoring component fixedly mounted at the upper end of the mounting plate, the adjustment structure comprising a housing fixedly mounted at the upper end of the support column, a sleeve rotatable around its own axis provided inside the housing, a horizontal plate fixedly connected to the upper end of the sleeve through the housing, vertical plates fixedly mounted at both ends of the horizontal plate, a connecting shaft rotatably connected between the two vertical plates via bearings, a connecting plate fixedly connected to the lower end of the mounting plate, one end of the connecting plate fixedly sleeved on the outside of the connecting shaft, a rotating shaft rotatably connected inside the sleeve, a first bevel gear fixedly mounted to the upper end of the rotating shaft through the horizontal plate, a second bevel gear meshing with the first bevel gear fixedly mounted on the outside of the connecting shaft, a first worm gear fixedly mounted to the lower end of the sleeve, and a second worm gear fixedly mounted to the lower end of the rotating shaft, the second worm gear being located below the first worm gear.

[0008] Furthermore, two drive motors are fixedly installed inside the housing, and the output ends of the two drive motors are each equipped with a worm gear via a coupling. One of the worm gears meshes with the first worm wheel, and the other worm gear meshes with the second worm wheel.

[0009] Furthermore, a cover plate is fixedly installed on the outer side of the outer casing by screws.

[0010] Furthermore, a protective shell is fixedly installed at the upper end of the horizontal plate, and both the first bevel gear and the second bevel gear are located in the internal cavity of the protective shell.

[0011] Furthermore, a top plate is provided at the upper end of the outer casing, the top plate is located directly below the monitoring component, and its two sides are inclined.

[0012] Furthermore, the upper end of the outer shell is provided with four vertical rods, and a ring is fixedly provided on the outer side of each vertical rod. A spring is fixedly installed on the upper end of the ring, and the other end of the spring is fixedly installed on the lower end of the top plate.

[0013] Furthermore, the upper end of the vertical rod is provided with an installation groove, and the lower end of the top plate is fixedly provided with a support rod, which is slidably connected inside the installation groove.

[0014] Furthermore, a damping telescopic rod is fixedly installed at the bottom of the mounting groove, and the output end of the damping telescopic rod is fixedly installed at the lower end of the support rod.

[0015] This utility model has the following beneficial effects:

[0016] (1) This utility model starts a drive motor meshing with a first worm gear. The drive motor drives the first worm gear to rotate through the worm at its output end. The first worm gear drives the sleeve to rotate around its own axis. The sleeve drives the mounting plate and the monitoring components on it to rotate horizontally through the horizontal plate, vertical plate, connecting shaft, and connecting plate. When it is necessary to adjust the pitch angle of the monitoring components, the drive motor meshing with a second worm gear is started. The drive motor drives the second worm gear to rotate through the worm at its output end. The second worm gear drives the rotating shaft to rotate. The first bevel gear at the upper end of the rotating shaft rotates accordingly and drives the second bevel gear meshing with it to rotate. The gear drives the connecting shaft to rotate within its bearing housing. The connecting shaft, through a connecting plate fixed to it, pushes one end of the mounting plate to swing around the axis of the connecting shaft, thereby changing the tilt angle of the mounting plate. This achieves the adjustment of the pitch angle of the monitoring component. Both worm gear pairs have self-locking characteristics, which can automatically lock the position after the drive motor stops, preventing the monitoring component from shifting due to its own weight. Through the set adjustment structure, the horizontal orientation and pitch angle of the monitoring component can be flexibly adjusted, avoiding the situation where the viewing angle of the monitoring equipment is fixed after installation and cannot be changed, and the field of view is strictly limited, thus achieving better flexibility and applicability.

[0017] (2) When a foreign object falls onto the top of the monitoring component, the top plate can protect the monitoring component. When the foreign object falls onto the top of the top plate, the impact force forces the top plate to move downward. The top plate presses down the spring and pushes the support rod to slide downward along the mounting groove of the vertical rod. At the same time, the damping telescopic rod is compressed. During this process, the spring undergoes elastic deformation to absorb the impact energy, while the damping force of the damping telescopic rod effectively converts the impact kinetic energy into heat energy and dissipates it. This allows the top plate to stop smoothly and quickly in the buffer position. After the impact ends, under the action of the spring's rebound force, the top plate pushes the support rod to slide upward and reset. The damping telescopic rod also suppresses its rebound speed to avoid violent reciprocating oscillations. Finally, the entire top plate returns to its initial position. At the same time, the combined use of the spring, support rod and damping telescopic rod during this process can reduce the impact of the impact force on the top plate and extend the service life of the top plate.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model discloses a fire prevention monitoring device for an energy storage photovoltaic power station, including a fixed base plate 1, a support column 2 fixedly connected to the upper end of the fixed base plate 1, an adjustment structure 3 provided at the upper end of the support column 2, an installation plate 4 provided at the upper end of the adjustment structure 3, and a monitoring component 5 fixedly installed at the upper end of the installation plate 4.

[0029] like Figures 1-4 As shown, this embodiment discloses a specific implementation method for adjusting the angle of the monitoring component 5 through the adjustment structure 3:

[0030] The adjusting structure 3 includes a housing 301 fixedly installed on the upper end of the support column 2. Inside the housing 301 is a sleeve 302 that can rotate around its own axis. The upper end of the sleeve 302 passes through the housing 301 and is fixedly connected to a horizontal plate 303. Vertical plates 304 are fixedly installed at both ends of the horizontal plate 303. A connecting shaft 305 is rotatably connected between the two vertical plates 304 via a bearing. A connecting plate 401 is fixedly connected to the lower end of the mounting plate 4, and one end of the connecting plate 401 is fixedly sleeved on... A rotating shaft 306 is rotatably connected to the outside of the connecting shaft 305 and the inside of the sleeve 302. The upper end of the rotating shaft 306 passes through the horizontal plate 303 and is fixedly installed with a first bevel gear 307. A second bevel gear 308 that meshes with the first bevel gear 307 is fixedly installed on the outside of the connecting shaft 305. A first worm gear 309 is fixedly installed on the lower end of the sleeve 302. A second worm gear 310 is fixedly installed on the lower end of the rotating shaft 306. The second worm gear 310 is located below the first worm gear 309.

[0031] Two drive motors 311 are fixedly installed inside the housing 301. The output ends of the two drive motors 311 are each equipped with a worm gear 312 via a coupling. One worm gear 312 meshes with the first worm wheel 309, and the other worm gear 312 meshes with the second worm wheel 310.

[0032] Among them, by driving the first worm gear 309 and the second worm gear 310 respectively by two independent drive motors 311, the direction and vertical pitch angle of the monitoring component 5 can be controlled separately, thus expanding the monitoring range;

[0033] A cover plate 313 is fixedly installed on the outside of the outer casing 301 by screws;

[0034] The cover plate 313 facilitates the installation, debugging and maintenance of the drive motor 311 and transmission mechanism inside the housing 301;

[0035] A protective shell 6 is fixedly installed on the upper end of the horizontal plate 303, and the first bevel gear 307 and the second bevel gear 308 are both located in the internal cavity of the protective shell 6;

[0036] Among them, the protective shell 6 isolates the bevel gear pair from the external environment, effectively preventing the intrusion of foreign objects such as dust and rainwater, and ensuring the reliability and service life of the transmission components;

[0037] Specifically, when it is necessary to adjust the horizontal orientation of the monitoring component 5, the drive motor 311 meshing with the first worm gear 309 is activated. This drive motor 311 drives the first worm gear 309 to rotate via the worm 312 at its output end. The first worm gear 309 drives the sleeve 302 to rotate around its own axis. The sleeve 302, through the horizontal plate 303, vertical plate 304, connecting shaft 305, and connecting plate 401, drives the mounting plate 4 and the monitoring component 5 on it to rotate horizontally together. When it is necessary to adjust the pitch angle of the monitoring component 5, the drive motor 311 meshing with the second worm gear 310 is activated. This drive motor 311 drives the first worm gear 309 to rotate via the worm 312 at its output end. The second worm gear 310 rotates, driving the rotating shaft 306 to rotate. The first bevel gear 307 at the upper end of the rotating shaft 306 rotates accordingly, driving the second bevel gear 308 meshing with it to rotate. The second bevel gear 308 drives the connecting shaft 305 to rotate within its bearing seat. The connecting shaft 305 pushes one end of the mounting plate 4 through the connecting plate 401 fixed thereto, causing it to swing around the axis of the connecting shaft 305, thereby changing the tilt angle of the mounting plate 4, thus realizing the adjustment of the pitch angle of the monitoring component 5. Both worm gear pairs have self-locking characteristics, which can automatically lock the position after the drive motor 311 stops, preventing the monitoring component 5 from shifting due to its own weight.

[0038] like Figure 3 and Figure 5 As shown, this embodiment discloses an implementation method for top buffer protection when a foreign object falls onto the monitoring component 5:

[0039] The upper end of the outer casing 301 is provided with a top plate 7, which is located directly below the monitoring component 5 and is inclined on both sides.

[0040] The top plate 7 is used to block foreign objects falling from above, preventing them from directly hitting the outer shell 301 or the adjustment structure 3 below. Its inclined side helps to guide the foreign objects to slide down.

[0041] The upper end of the outer casing 301 is provided with four vertical rods 314. A ring body 315 is fixedly provided on the outer side of each vertical rod 314. A spring 8 is fixedly installed on the upper end of the ring body 315, and the other end of the spring 8 is fixedly installed on the lower end of the top plate 7.

[0042] Among them, the elastic support of the spring 8 provides a buffer for the top plate 7, which can absorb most of the impact energy when a foreign object falls and hits it.

[0043] The upper end of the vertical rod 314 is provided with an installation groove, and the lower end of the top plate 7 is fixedly provided with a support rod 701, which is slidably connected inside the installation groove.

[0044] The sliding fit between the support rod 701 and the mounting groove provides a stable guide for the up-and-down buffer movement of the top plate 7, preventing it from tilting or getting stuck.

[0045] A damping telescopic rod 9 is fixedly installed at the bottom of the mounting slot, and the output end of the damping telescopic rod 9 is fixedly installed at the lower end of the support rod 701.

[0046] Among them, the damping telescopic rod 9 is used to dissipate the vibration energy generated by the spring 8 during compression and rebound, which can quickly attenuate the shaking of the top plate 7 and prevent it from vibrating for a long time.

[0047] Specifically, when a foreign object falls onto the top plate 7, the impact force forces the top plate 7 to move downwards. The top plate 7 presses down on the spring 8 and pushes the support rod 701 to slide downwards along the mounting groove of the vertical rod 314. At the same time, it compresses the damping telescopic rod 9. During this process, the spring 8 undergoes elastic deformation to absorb the impact energy, while the damping force of the damping telescopic rod 9 effectively converts the impact kinetic energy into heat energy and dissipates it. This allows the lower end of the top plate 7 to stop smoothly and quickly at the position in contact with the upper end of the vertical rod 314. After the impact ends, under the action of the spring 8's rebound force, the top plate 7 pushes the support rod 701 to slide upwards and reset. The damping telescopic rod 9 also suppresses its rebound speed to avoid violent reciprocating oscillations, ultimately allowing the entire top plate 7 to return to its initial position.

[0048] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
