Description

Technical Field

[0001] The invention relates to the technical field of video monitoring, in particular to a movable video monitoring device with photovoltaic energy. Background Art

[0002] Mobile video surveillance equipment is a device that can flexibly change its position to achieve video surveillance functions. It usually includes various forms such as universal wheels or directional wheels. The video acquisition part includes a camera with various lens types, such as wide-angle lenses that can cover a larger range and telephoto lenses that can focus on distant targets. The power system can have a built-in large-capacity battery to provide power for the movement and operation of the equipment. Some devices also support external power supplies, such as solar charging panels, to ensure continuous power supply in special environments such as outdoors.

[0003] In today's security monitoring field, mobile monitoring equipment plays an important role. Such equipment usually needs to be flexibly deployed in different locations and scenarios to meet diverse monitoring needs. Most of the existing mobile monitoring equipment has universal wheels installed at the bottom to achieve mobility. This design does facilitate the transportation of the equipment during movement, and staff can easily push the monitoring equipment to the designated monitoring location.

[0004] When the existing mobile monitoring equipment reaches the predetermined position and stops moving, it is only fixed by the brake plate on the universal wheel. The friction between the brake plate and the ground is limited, and the structural characteristics of the universal wheel itself determine that it is easy to slip when subjected to external forces. For example, in common situations such as when people walk, objects collide, or the ground vibrates slightly, the entire monitoring equipment is prone to displacement due to the lack of a more effective stabilization mechanism. This displacement may cause the monitoring range to change and fail to accurately cover the preset monitoring area, thereby affecting the monitoring effect and possibly missing key monitoring information. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a mobile video surveillance device with photovoltaic energy to solve the technical problem that the mobile surveillance equipment in the prior art uses universal wheels to move when moving, but when not moving, the universal wheels are only locked by the brake plates of the universal wheels, resulting in poor overall stability.

DETAILED DESCRIPTION

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] The following describes an embodiment of the present invention based on its overall structure.

[0039] A mobile video surveillance device with photovoltaic energy, such as Figure 1-12 As shown, it includes a base 1 and a rod body 2 fixedly connected to the top thereof. The base 1 provides a stable supporting foundation for the entire device and bears the weight of the rod body 2 and other internal components. The rod body 2 connects and supports other components, such as a wrench mechanism 4, a hydraulic adjustment mechanism 6, a connecting rod mechanism 8, etc., providing a structural framework for their installation and operation, ensuring a reasonable layout of various components in space, and making the overall structure of the device compact and stable.

[0040] A wrench mechanism 4 is arranged in the fixing frame 3 located inside the bottom of the rod body 2 on both sides. The wrench mechanism 4 includes a wrench body 401, a locking rod 402, a lifting frame 403, a first inclined block 404, a pressing plate 405, a second inclined block 406, a lifting rod 407, a blocking bar 408 and a spring 409;

[0041] The wrench body 401 is a component to which the operator applies force, and triggers a series of actions by rotating around the shaft. It is located inside the fixing frame 3 and is connected to the fixing frame 3 by the shaft. This connection mode enables the wrench body 401 to rotate flexibly within a certain range, providing the possibility for subsequent operations;

[0042] The locking rod 402 is fixed on both sides of the wrench body 401. Its main function is to cooperate with the limiting mechanism 5 to achieve locking and unlocking of the wrench body 401 at different positions. During the transition between the moving and fixed states of the device, the locking rod 402 ensures that the wrench body 401 remains stable in the correct position through specific interaction with the limiting head 502 (such as arc surface sliding connection), thereby preventing the device state from changing due to misoperation;

[0043] The gear 11 fixed on the outer side of the internal rotating shaft of the wrench body 401 meshes with the lifting gear block 10 and is a key component for converting the rotation of the wrench body 401 into the linear motion of the lifting gear block 10. When the wrench body 401 rotates, the gear 11 rotates accordingly, driving the lifting gear block 10 to rise or fall, thereby realizing the driving of the hydraulic adjustment mechanism 6;

[0044] The lifting frame 403 is located inside the wrench body 401 and is slidably connected. The first inclined block 404 fixed at the bottom end thereof and the second inclined block 406 fixed at the bottom of the pressing plate 405 form an inclined sliding connection. This design enables the second inclined block 406 to push the first inclined block 404 and the lifting frame 403 down when the pressing plate 405 is pressed, and then the blocking bar 408 is driven down through the lifting rod 407 to release the blocking of the limit head 502 and the locking rod 402, creating conditions for the flipping of the wrench body 401.

[0045] The pressing plate 405 is convenient for the operator to press with his fingers, and is the starting point for starting the unlocking process of the wrench body 401. The pressing action of the pressing plate 405 can trigger the linkage of a series of internal mechanical structures to achieve the switching preparation of the equipment state;

[0046] A blocking bar 408 is fixed on the top of the lifting rod 407, which not only drives the blocking bar 408 to descend and release the lock when the lifting frame 403 descends, but also, under the action of the spring 409, can make the blocking bar 408 contact the bottom of the limit head 502 in normal state, further ensuring the overall stability and preventing the wrench body 401 from accidentally rotating when the device does not need to move;

[0047] The spring 409 plays a role of resetting and auxiliary locking in the entire wrench mechanism 4. When the wrench body 401 is not turned over, the elastic force of the spring 409 keeps the lifting rod 407 in an upward trend, so that the blocking bar 408 forms a stable resistance to the limit head 502, ensuring that the relative positions of the various components are stable when the device is in a fixed state;

[0048] Specifically, the top and bottom of one side of the two sets of fixing frames 3 are both provided with a limiting mechanism 5, which includes a fixing block 501, a limiting head 502 and an elastic sheet 503;

[0049] The fixing block 501 is fixed to one side of the fixing frame 3 to provide a mounting base for the limiting head 502, ensuring that the limiting head 502 can accurately match the locking rod 402 at the fixed position;

[0050] The limit head 502 is slidably connected to the fixed block 501 and is elastically connected therebetween via an elastic sheet 503. The main function of the limit head 502 is to cooperate with the locking rod 402 to limit the rotation of the wrench body 401. When the device is fixed, the limit head 502 clamps the locking rod 402 under the elastic force of the elastic sheet 503 to prevent the wrench body 401 from rotating.

[0051] When the locking rod 402 is subjected to a certain external force (such as the squeezing force when the wrench body 401 is turned over), the limit head 502 can slide on the fixed block 501 and compress the elastic sheet 503, so that the locking rod 402 passes smoothly, the turning operation of the wrench body 401 is realized, and the conversion of the device state is completed;

[0052] The elastic sheet 503 provides elastic restoring force for the limit head 502, ensuring that the limit head 502 can quickly return to the initial position when no external force is applied or the external force disappears, and effectively blocks the locking rod 402 again, thereby maintaining the stability of the device state;

[0053] A hydraulic adjustment mechanism 6 is provided at the center of the base 1, including an output hydraulic cylinder 601, an input hydraulic cylinder 602, a connecting pipe 603, an output piston 604 and a connecting ring 605;

[0054] The output hydraulic cylinder 601 and the input hydraulic cylinder 602 are connected through the connecting pipe 603 to form a hydraulic transmission system. When the lifting gear block 10 descends and drives the piston rod 12 to descend along the input hydraulic cylinder 602, the hydraulic oil inside the input hydraulic cylinder 602 enters the output hydraulic cylinder 601 through the connecting pipe 603, pushing the output piston 604 to extend and descend. The output hydraulic cylinder 601 is located outside the input hydraulic cylinder 602 and is fixedly connected to the base 1, providing stable support and guidance for the entire hydraulic adjustment process, ensuring that the flow of hydraulic oil in the cylinder can be accurately converted into the linear motion of the piston, thereby realizing the control of the moving mechanism 7;

[0055] The output piston 604 is located inside the output hydraulic cylinder 601 and is slidably connected. Its main function is to perform linear motion under the impetus of hydraulic oil, and transmit the motion to the telescopic connecting rod 703 through the connecting ring 605, thereby driving the universal wheel 702 to extend or retract, thereby realizing the switching of the mobile function of the equipment;

[0056] The inner side of the connecting ring 605 is fixedly connected to the output piston 604, and the outer side is connected to the telescopic connecting rod 703, which plays the role of connecting and transmitting power. It converts the linear motion of the output piston 604 into a pulling force or a thrust force on the telescopic connecting rod 703, so that the adjustment frame 701 drives the universal wheel 702 to complete the corresponding action, ensuring the smooth conversion of the equipment between the mobile and fixed states;

[0057] The base 1 is provided with a moving mechanism 7 at the four corners thereof, including an adjustment frame 701, a universal wheel 702, a telescopic connecting rod 703 and a guide rail 704;

[0058] The adjustment frame 701 is fixed at the four corners of the outer side of the connection ring 605, and is the middle component connecting the universal wheel 702 and the telescopic connecting rod 703. Its function is to guide the universal wheel 702 to slide linearly along the guide track 704 under the drive of the telescopic connecting rod 703, so as to realize the extension and retraction of the universal wheel 702, thereby changing the support and movement mode of the device;

[0059] The universal wheel 702 is a key component for realizing the mobile function of the device. It can be flexibly rotated under various ground conditions, so that the device can be easily moved to a designated position. When the device needs to be moved, the universal wheel 702 extends out of the base 1 and contacts the ground, and the translation of the device is realized by rotation. After the device reaches the predetermined position, the universal wheel 702 retracts into the base 1, and the base 1 directly contacts the ground to provide stable support;

[0060] The telescopic connecting rod 703 is a telescopic structure, one end of which is fixedly connected to the connecting ring 605, and the other end is connected to the adjusting frame 701. When the hydraulic adjustment mechanism 6 is working, as the connecting ring 605 rises and falls, the telescopic connecting rod 703 can be correspondingly extended and retracted, and the power is accurately transmitted to the adjusting frame 701, ensuring the smooth extension and retraction of the universal wheel 702, and in the process of moving the equipment, it can adapt to different height changes and keep the universal wheel 702 in good contact with the ground;

[0061] The guide rails 704 are fixed at the four corners of the inner wall of the base 1 and penetrate the adjustment frame 701. The main function of the guide rails 704 is to provide accurate guidance for the sliding of the adjustment frame 701, limit the movement direction of the adjustment frame 701, and make it slide only along a predetermined straight line direction, thereby ensuring the accuracy and stability of the extension and retraction of the universal wheel 702, and preventing the adjustment frame 701 from deflecting or shaking during the movement, thereby ensuring the reliable realization of the mobile function of the device;

[0062] A transmission rod 9 extending to the inside of the rod body 2 is fixed on the top of the lifting gear block 10, and the two sides of the top of the rod body 2 are rotatably connected with a support rod 13 and a support plate 15 respectively. The two sides of the top of the transmission rod 9 and the support rod 13 and the support plate 15 are connected through a connecting rod mechanism 8, and the connecting rod mechanism 8 includes a transmission slider 801 and a matching connecting rod 802;

[0063] The transmission rod 9 plays the role of transmitting the movement of the lifting gear block 10, converting the linear lifting movement of the lifting gear block 10 into driving the connecting rod mechanism 8. When the lifting gear block 10 descends, the transmission rod 9 also descends, driving the transmission slider 801 to slide inside the rod body 2, and then realizing the folding or unfolding action of the support rod 13 and the support plate 15 through the cooperation of the connecting rod 802;

[0064] A video monitoring module 14 is fixed on the outside of the support rod 13, and its main function is to provide stable support for the video monitoring module 14, to ensure that the video monitoring module 14 can be kept in a suitable position and angle during operation, and to obtain accurate monitoring images. When the device is moved, the support rod 13 can be folded and retracted under the action of the connecting rod mechanism 8, to reduce the overall space occupied by the device, and to facilitate movement. After reaching the designated position, it can be restored to the initial position under the drive of the connecting rod mechanism 8, to ensure the normal operation of the video monitoring module 14;

[0065] A photovoltaic panel 16 is connected obliquely between the support plate 15 and the rod body 2. Firstly, it provides a mounting base for the photovoltaic panel 16 so that the photovoltaic panel 16 can be kept in an inclined state to obtain the best illumination angle and improve the power generation efficiency. Secondly, when the device moves, the support plate 15 can drive the photovoltaic panel 16 to fold and retract under the action of the connecting rod mechanism 8 to avoid damage to the photovoltaic panel 16 during the movement, and also reduce the space occupied by the device.

[0066] One end of the photovoltaic panel 16 is rotatably connected to the rod body 2, and the other end is slidably and rotatably connected to the support plate 15. This connection method enables the photovoltaic panel 16 to be flexibly folded and unfolded during the device state conversion process to adapt to different work requirements;

[0067] The two sets of transmission sliders 801 are slidably connected with the rod body 2 and fixed on the outside of the transmission rod 9. They are the key components in the connecting rod mechanism 8 that receive the power of the transmission rod 9 and convert it into a force on the support rod 13 and the support plate 15. When the transmission rod 9 descends, the transmission slider 801 slides relatively in the rod body 2, and converts the downward linear motion into a pulling force on the support rod 13 and the support plate 15 by cooperating with the connecting rod 802, so that they can be folded and retracted. Conversely, when the transmission rod 9 rises, the transmission slider 801 slides in the opposite direction, pushing the support rod 13 and the support plate 15 to unfold to the initial position;

[0068] The connecting rod 802 connects the transmission slider 801 with the support rod 13 and the support plate 15, and plays a role in force transmission and conversion. It can convert the linear motion into the rotation or folding motion of the support rod 13 and the support plate 15 according to the movement of the transmission slider 801, so as to realize the conversion of different structural forms of the equipment in the mobile and fixed states, ensure the coordinated work between the various components of the equipment, and improve the overall performance and reliability of the equipment;

[0069] When in use, the support rod 13 supports the video surveillance module 14 so that the video surveillance module 14 can stably monitor the target area. The support plate 15 keeps the photovoltaic panel 16 tilted to generate electricity and provide clean energy for the equipment. The base 1 has a power storage module, a power supply module, a control module and a wireless receiving module inside to ensure the operation of the equipment. At this time, the four groups of moving mechanisms are retracted into the base 1, and the bottom of the base 1 is in contact with the ground. The stability is ensured by gravity and anti-skid pads (or additional fixing strips). The anti-skid pads increase the friction between the base 1 and the ground to prevent the equipment from sliding when subjected to slight external forces. The additional fixing strips can be better inserted into the ground on soft land or grass to provide additional support and anchoring force, further enhancing the stability of the equipment under different ground conditions.

[0070] When the equipment needs to be moved, the staff member turns the two sets of wrench mechanisms 4 180 degrees from bottom to top with both hands, first presses the pressing plate 405, and turns over the wrench body 401 after removing the obstruction. After turning over, the locking rod 402 is locked with the upper limiting mechanism 5. The action of pressing the pressing plate 405 triggers the mechanical linkage inside the wrench mechanism 4, so that the blocking bar 408 descends, and the obstruction to the limiting head 502 and the locking rod 402 is removed, creating conditions for the turning over of the wrench body 401. After the wrench body 401 is turned over, the locking rod 402 is locked with the upper limiting mechanism 5, ensuring that the wrench body 401 remains stable in the new position, and preparing for the subsequent equipment state conversion operation;

[0071] The wrench body 401 turns over to drive the gear 11 to rotate, so that the lifting gear block 10 descends, and then drives the hydraulic adjustment mechanism 6 to make the universal wheel 702 extend out of the base 1. At the same time, the transmission rod 9 descends to drive the connecting rod mechanism 8 to fold and retract the support rod 13 and the support plate 15. The video monitoring module 14 and the photovoltaic panel 16 are folded to reduce space occupation, lower the center of gravity, facilitate movement, increase passability and make it more stable. Then the staff can push the equipment to move;

[0072] The rotation of the wrench body 401 is precisely converted into the movement of the piston in the hydraulic adjustment mechanism 6 through the meshing of the gear 11 and the lifting gear block 10, thereby realizing the extension of the universal wheel 702. In this process, the coordinated work of the connecting rod mechanism 8 ensures the folding and retraction of the support rod 13 and the support plate 15. The folding of the video monitoring module 14 and the photovoltaic panel 16 not only reduces the space occupied by the device during the movement and avoids collision with surrounding objects, but also lowers the center of gravity of the device, improves the stability of the device during the movement, and reduces the risk of shaking and tipping;

[0073] After moving to the designated position, the staff manually flips the two sets of wrench bodies 401 180 degrees from top to bottom again, the wrench body 401 engages with the lower limit mechanism 5, the moving mechanism 7 is retracted into the base 1, the bottom of the base 1 contacts the ground, and the support rod 13 and the support plate 15 return to the initial state under the action of the connecting rod 802, and the equipment resumes normal operation. The flipping of the wrench body 401 again returns the equipment to the fixed state, and the retraction of the moving mechanism 7 makes the base 1 become the main supporting component again, contacting the ground to provide stable support. The restoration of the support rod 13 and the support plate 15 returns the video monitoring module 14 and the photovoltaic panel 16 to the working position, and the equipment can continue to monitor and generate electricity normally, ensuring the reliable conversion and stable operation of the equipment between different working states.

[0074] The working principle of the present invention is as follows: when in use, the support rod 13 plays a supporting role for the video monitoring module 14, wherein the video monitoring module 14 can perform a video monitoring process, wherein under the action of the support plate 15, the photovoltaic panel 16 is kept tilted, and then the power generation operation can be performed by sunlight, wherein a power storage module, a power supply module, a control module and a wireless receiving module are arranged inside the base 1, thereby ensuring the overall operating state of the present application;

[0075] When in use, the four groups of moving mechanisms are retracted into the base 1, so that the bottom of the base 1 contacts the ground. Combined with the overall gravity, the overall stability can be ensured by the base 1.

[0076] When the whole needs to be moved, the staff uses both hands to turn the two sets of wrench mechanisms 4 from bottom to top by 180 degrees;

[0077] Furthermore, when the staff member turns the two sets of wrench bodies 401, the staff member first presses the pressing plate 405 with his fingers, and the pressing plate 405 moves to drive the second inclined block 406 to slide. Since the second inclined block 406 and the first inclined block 404 are connected by an inclined sliding surface, the first inclined block 404 and the lifting frame 403 are driven to descend under the sliding action of the second inclined block 406. The lifting frame 403 descends and drives the two sets of blocking bars 408 to descend through the two sets of lifting rods 407. At this time, the blocking bars 408 descend and are free from blocking the limit head 502 and the locking rod 402.

[0078] At this time, the staff member applies a certain force on the hand as a whole. Since the locking rod 402 and the limit head 502 are connected by an arc surface sliding connection, the locking rod 402 can actively squeeze the limit head 502 as the wrench body 401 moves, so that the limit head 502 shrinks and breaks away from the obstruction of the locking rod 402, and the wrench body 401 can be flipped.

[0079] Furthermore, when the wrench body 401 is turned 180 degrees from bottom to top, the two sets of locking rods 402 of the wrench body 401 are locked and connected with the upper limiting mechanism 5 again to prevent the wrench body 401 from loosening.

[0080] Specifically, a spring 409 is provided between the lifting rod 407 and the wrench body 401, and when the wrench body 401 is not turned over, the spring 409 can cause the blocking bar 408 to contact the bottom of the limit head 502, thereby further ensuring the overall stability.

[0081] When the wrench body 401 drives the gear 11 to rotate through the shaft, the gear 11 rotates to engage the lifting gear block 10 to descend, and the lifting gear block 10 descends to drive the piston rod 12 to descend along the input hydraulic cylinder 602. At this time, the hydraulic oil in the input hydraulic cylinder 602 enters the output hydraulic cylinder 601 through the connecting pipe 603, and then the hydraulic oil enters the output hydraulic cylinder 601 to push the output piston 604 to extend and descend;

[0082] When the output piston 604 descends, the telescopic connecting rod 703 can be driven to descend through the connecting ring 605, so that the universal wheels 702 can be driven to extend out of the base 1 through the adjusting frame 701, so that the bottoms of the four sets of universal wheels 702 are located below the bottom of the base 1, and the staff can move the whole;

[0083] When the four sets of universal wheels 702 extend out of the base 1, at the same time, the lifting gear block 10 descends to drive the transmission rod 9 to descend, and then the transmission rod 9 drives the transmission sliders 801 of the two sets of connecting rod mechanisms 8 to slide downward relative to the inside of the rod body 2, and under the action of the matching connecting rods 802, the two sets of matching connecting rods 802 can respectively fold and retract the support rod 13 and the support plate 15;

[0084] That is to say, at this time, the support rod 13 drives the video monitoring module 14 to fold and retract, and the support plate 15 drives the photovoltaic panel 16 to fold and retract, so that when the whole is moved, the folding and retraction of the video monitoring module 14 and the photovoltaic panel 16 effectively reduces the space occupied by the whole, thereby improving the passability of the whole during movement, and at the same time lowers the center of gravity position of the whole rod body 2, ensuring that the whole is more stable during movement, and effectively avoiding the risk of shaking or even toppling over during movement;

[0085] After the whole body moves to the designated position, the staff manually flips the two sets of wrench bodies 401 from top to bottom by 180 degrees again. The flipped wrench bodies 401 are engaged with the limit mechanism 5 below. At this time, the four sets of moving mechanisms 7 are retracted into the inside of the base 1, so that the bottom of the base 1 is directly in contact with the ground, thereby improving the overall stable supporting force. At the same time, the support rod 13 driving the video monitoring module 14 and the support plate 15 driving the photovoltaic panel 16 rotate to the initial state under the action of the connecting rod 802, and normal operation is restored.

[0086] A non-slip pad is fixed at the bottom of the base 1, which ensures that the friction between the base 1 and the ground is increased after the base 1 comes into contact with the ground, further improving the overall stability. A raised fixing strip can also be installed at the bottom of the base 1 to facilitate the supporting effect of the base 1 on soft soil or grass.
