Description

Technical Field

[0001] This invention relates to the field of monitoring technology, and in particular to a field monitoring system for a dual-power mobile substation in an open-pit coal mine. Background Technology

[0002] Open-pit coal mines refer to coal seams deposited on the surface or in shallow layers due to geographical changes, and are mined directly in the open. Mobile prefabricated substations, on the other hand, are fully sealed and fully insulated, ensuring reliable personal safety. They are small in size and compact in structure (the product occupies only 1 / 3 the space of a European-style prefabricated substation of the same capacity), and are easy and flexible to install. They can be used in ring networks or as terminals, and are easy to switch between, greatly improving the reliability of power supply.

[0003] To ensure safe operation during the use of mobile substations, a temporary monitoring system is usually set up at the substation site. Staff members can monitor the operation of various components at the substation site by checking the monitoring system.

[0004] Surveillance cameras are typically supported by wall mounts or tripods. To ensure as much coverage as possible without blind spots, cameras are usually installed at a high position to monitor the substation site.

[0005] However, existing surveillance cameras have certain drawbacks when applied to substation sites. Since the surveillance cameras will be installed outdoors, in order to achieve as much coverage as possible without blind spots, the surveillance cameras need to be at a certain height. However, outdoor weather is unpredictable. If a strong wind suddenly blows, the surveillance cameras at a high position are very likely to tip over, thereby causing certain damage to the equipment.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figures 1-7 This is the first embodiment of the present invention, which provides a field monitoring system for a dual-power mobile substation in an open-pit coal mine. The monitoring camera component can meet the height requirements for outdoor operations.

[0032] Specifically, the tripod body 100 includes a support assembly 101 located outside the tripod body 100, and the support assembly 101 includes an upright plate 102; a load-bearing assembly 200 includes a mounting frame 201 movably connected to the upright plate 102 and a transmission ring 202 located within the mounting frame 201; and a monitoring camera assembly 300 includes a camera body 301, a support frame 302 located outside the camera body 301 and detachably connected to the mounting frame 201, and a wind guide assembly 303 located outside the camera body 301.

[0033] The tripod body 100 is adjustable in the support angle of each leg (as fully documented in the prior art), which can meet the requirements for support on rugged terrain.

[0034] In summary, when performing outdoor operations, the tripod body 100 is fixed and installed on the working ground. In the factory default state, the monitoring camera component 300 and the load-bearing component 200 are separate, while the load-bearing component 200 is mounted on the support component 101, which provides support for the load-bearing component 200 at a certain height.

[0035] Example 2

[0036] Reference Figures 1-4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the protective box X not only allows the bearing component 200 to be movably connected to the support component 101, but also protects the various transmission gears outside the mounting frame 201 from being contaminated.

[0037] Specifically, the upright plate 102 is provided with a first sliding groove 102a, and a first channel 102a-1 is provided through the first sliding groove 102a. A transmission rack 102b is provided outside the upright plate 102. A protective component 205 is provided outside the mounting frame 201. The protective component 205 includes a protective box X. A second channel 205a is provided through the protective box X. A first slider 205b that can slide with the first sliding groove 102a is screwed to the protective box X. A third channel 205b-1 is provided through the first slider 205b. A second slider 201a is provided inside the mounting frame 201. An abutment groove 201b is integrally injection molded outside the mounting frame 201. A fourth channel 201c is provided through the mounting frame 201. A support frame 302 is provided outside the support frame 302. The mounting frame 201 has a second slide groove 302a that can slide with the second slider 201a. The mounting frame 201 has a first split shaft 203 and a first transmission gear 203b outside the first split shaft 203. One end of the first split shaft 203 extends into the protective box X and is provided with a second transmission gear 203a. A handle 103 can also be detached from one end of the first split shaft 203. The mounting frame 201 has second split shafts 204 on both sides. One end of the second split shaft 204 is provided with a third transmission gear 204a that can mesh with the second transmission gear 203a. The other end of the second split shaft 204 is provided with a fourth transmission gear 204b. The outer wall of the fourth transmission gear 204b meshes with the transmission rack 102b through the second through channel 205a.

[0038] When connecting the support component 200 and the monitoring camera component 300, it is only necessary to align the second slide groove 302a outside the support frame 302 with the second slider 201a and insert it, so that the camera body 301 enters the mounting frame 201. The camera body 301 can be fixed by its own weight. At this time, the camera body 301 will contact the abutment groove 201b and complete the limiting.

[0039] When lifting and lowering the load-bearing component 200, the handle 103 can be inserted into the protective box X through the first channel 102a-1 and the third channel 205b-1 in sequence, and contact the first sub-shaft 203. Then, the handle 103 is rotated to drive the first sub-shaft 203 to rotate. The first sub-shaft 203 in the rotating state will mesh with the second transmission gear 203a and the third transmission gear 204a, so that each second sub-shaft 204 drives each fourth transmission gear 204b to rotate. Based on the meshing of the fourth transmission gear 204b with the transmission rack 102b, the first slider 205b is lifted and lowered within the stroke of the first slide groove 102a, thereby realizing the displacement of the load-bearing component 200 and meeting the height requirements of the monitoring camera component 300 during operation.

[0040] Example 3

[0041] Reference Figures 1-7 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to avoid the monitoring camera component 300 being in a high position and easily overturned by strong winds, the monitoring camera component 300 will be vertically moved downwards in windy weather to lower the center of gravity and improve stability.

[0042] Specifically, the transmission ring 202 has an output gear 202b that can mesh with the first transmission gear 203b, and a slot 202a is provided inside the transmission ring 202. The air guide assembly 303 includes a main shaft 303a, one end of which extends into the transmission ring 202 and is provided with a control assembly 304. The other end of the main shaft 303a is provided with a fixing post 303a-1, and a first connecting rod 303a-2 is arranged around the fixing post 303a-1. One end of the first connecting rod 303a-2 is screwed to an air guide frame 303a-21. The control assembly 304 includes a component that connects to the main shaft 303a-2. A turntable 305 is screwed to the turntable 305, and a movable claw 305a is provided on the outer matrix of the turntable 305, which can engage with the slot 202a. A connecting channel 305a-1 is provided through the movable claw 305a. A fixing block 305b is screwed to the outer array of the turntable 305, and a second connecting rod 305b-1 is movably provided on the outer matrix of the fixing block 305b. One end of the second connecting rod 305b-1 extends into the movable claw 305a, and one end of the second connecting rod 305b-1 passes through the connecting channel 305a-1 and is provided with a limiting ring 305b-2. An elastic element 305b-11 is provided on the outer sleeve of the second connecting rod 305b-1.

[0043] When the monitoring camera component 300 is connected to the carrier component 200, the output gear 202b will be inserted into the lower part of the inner cavity of the mounting frame 201 through the fourth channel 201c and mesh with the first transmission gear 203b.

[0044] Considering that there is still some wind in a relatively open outdoor environment, and that when the wind force is small, the wind guide component 303 will not drive the transmission ring 202 to rotate.

[0045] In summary, in windy weather, the wind will cause the wind guide frame 303a-21 inside the wind guide assembly 303 to rotate at high speed, thereby driving the main shaft 303a into a rotating state. The high-speed rotation of the main shaft 303a will cause the movable claw 305a outside the turntable 305 to undergo centrifugal motion, that is, one end of the movable claw 305a will be thrown out. During this throwing action, the limiting ring 305b-2 will move within the connecting channel 305a-1, pulling the second link 305b-1 to move. The displacement of the second link 305b-1 will cause the elastic element 305b-11 to be stressed. The elastic element 305b-11 is a compression spring, and the elastic element 305b-11 can facilitate the second link 305b-1 to pull the movable claw 305a back to its original position.

[0046] When one end of the movable claw 305a is thrown out, it will engage with 202a on the transmission ring 202, thereby causing the transmission ring 202 to rotate. That is, the transmission ring 202 can only rotate in windy weather. If the wind is weak, the movable claw 305a will not rotate and will not drive the transmission ring 202 to rotate.

[0047] When the transmission ring 202 rotates, the first sub-shaft 203 rotates on the basis of the meshing of the output gear 202b and the first transmission gear 203b, thereby realizing the overall movement of the bearing assembly 200. The rotation of the first sub-shaft 203 to realize the movement of the bearing assembly 200 has been described in Embodiment 2.

[0048] Finally, it should be noted that a ratchet is provided outside the main shaft 303a, and a pawl that engages with the ratchet is provided inside the camera body 301. This means that the main shaft 303a can only rotate in one direction. When it is required to reverse, the pawl needs to be controlled to disengage from the ratchet. The engagement between the ratchet and the pawl is fully described in the prior art and will not be elaborated on here.
