Description

Technical Field

[0001] This invention relates to the field of fully mechanized coal mining technology, and in particular to an installation device that facilitates the self-cleaning of open-pit mine signs. Background Technology

[0002] Open-pit mining is a common method of mineral extraction, typically used for mining open-pit deposits such as coal, iron ore, copper ore, and gold ore. This method involves removing surface soil and rock layer by layer to expose the ore deposit. Heavy equipment such as excavators, loaders, and transport vehicles are then used to transport the ore from the mining area to a processing plant for further processing. Open-pit mining has several advantages and challenges. One advantage is its relatively low mining cost, as it eliminates the need for underground excavation and support works, and avoids the use of expensive equipment. Furthermore, open-pit deposits are typically large, and the exposed ore surface during mining is relatively large, resulting in relatively high productivity.

[0003] The construction site of open-pit mines is large, and production vehicles and commuter vehicles operate in close proximity, with long transportation distances and high risks. As a result, there are many signs at open-pit mine sites. Due to the high level of dust at open-pit mine sites, these signs can become covered with a thick layer of dust within a few days, making it difficult for drivers to intuitively follow the information on the signs. Therefore, it is often necessary to arrange for dedicated personnel to clean the signs. However, the complex environment of open-pit mines poses significant safety hazards to the personnel responsible for cleaning the signs. Summary of the Invention

[0021] 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.

[0022] 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.

[0023] 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.

[0024] Example 1 Reference Figures 1-2This is the first embodiment of the present invention. This embodiment provides a self-cleaning installation device for open-pit mine signs. The self-cleaning installation device for open-pit mine signs includes a clamping component 100, a rotating component 200, and a limiting component 300. The user clamps the sign surface with the clamping component 100, and the sign surface is automatically cleaned in windy weather by rotating the rotating component 200. At the same time, the limiting component 300 stops the rotating component 200 from rotating in windy weather to prevent the rotating component 200 from rotating too fast and being damaged.

[0025] Specifically, the clamping assembly 100 includes a housing 101 and a telescopic member 102. The telescopic member 102 is movably disposed on the side of the housing 101. When the user places the card face inside the housing 101, the telescopic member 102 adopts a spring structure, which can automatically clamp the card face after it is placed in the housing 101.

[0026] Preferably, the rotating assembly 200 includes an impeller 201, a rotating component 202, a swing component 203, a latching component 204, and an extension component 205. The rotating component 202 is rotatably disposed on the side of the housing 101, the impeller 201 is fixedly disposed on the other end of the rotating component 202, the swing component 203 is rotatably disposed on the upper end of the rotating component 202, the latching component 204 is fixedly disposed on the side of the swing component 203, and the extension component 205 is rotatably disposed on the side of the swing component 203. When the sign is in windy weather, it blows the impeller 201 to rotate, the rotation of the impeller 201 drives the rotating component 202 to rotate, which in turn drives the swing component 203 to rotate, and finally drives the extension component 205 to move left and right. The latching component 204 is adjusted along with the telescopic component 102 according to the actual size of the sign placed inside, and similarly, the extension component 205 is also adjusted vertically according to the size of the sign placed inside the housing 101.

[0027] Furthermore, the limiting component 300 includes a gear 301, a first latching member 302, a second latching member 303, and a rotating block 304. The gear 301 is rotatably mounted on the bottom end of the impeller 201, and the rotating block 304 is rotatably mounted on the bottom end of the gear 301. The first latching member 302 is movably mounted on the side of the gear 301, and the second latching member 303 is movably mounted on the other side of the gear 301. The first latching member 302 engages with the gear 301, and the second latching member 303 engages with the gear 301. When the impeller 201 rotates, it drives the gear 301 and the rotating block 304 to rotate. When the airflow is low, the rotating block 304 engages with the first latching member 302 and the second latching member 303, but cannot push the first latching member 302 or the second latching member 303 to the predetermined position. Therefore, the gear 301... 1. Continue to rotate without being jammed. When the air volume is too large, the impeller 201 rotates, driving the gear 301 and the rotating block 304 to rotate. At the same time, the rotating block 304 rotates too fast, thus pushing the first latching member 302 or the second latching member 303 to the predetermined position. Thus, the first latching member 302 or the second latching member 303 can latch the gear 301. When the first latching member 302 or the second latching member 303 latches the gear 301, the rotating block 304 stops rotating, and the first latching member 302 and the second latching member 303 reset. Then the gear 301 can continue to work normally. Under the blowing of strong wind, the impeller 201 continues to drive the rotating block 304 to rotate, and the first latching member 302 or the second latching member 303 pushes to the predetermined position. Thus, the cycle repeats, and the impeller 201 is limited and no longer rotates.

[0028] In use, after the sign is placed in the housing 101, the telescopic component 102 automatically clamps the sign. When the sign is in windy weather, it blows the impeller 201 to rotate. The rotation of the impeller 201 drives the rotating component 202 to rotate, which in turn drives the oscillating component 203 to rotate, ultimately causing the extension component 205 to move left and right. When the airflow is low, the rotating block 304 engages the first latching component 302 and the second latching component 303, but cannot push the first latching component 302 or the second latching component 303 to the predetermined position. Therefore, the gear 301 continues to rotate and is not engaged. When the airflow is high, the rotation of the impeller 201 drives the gear 301 and the rotating block 304 to rotate. At the same time, the rotating block 304 rotates too fast, which pushes the first latching member 302 or the second latching member 303 to a predetermined position, so that the first latching member 302 or the second latching member 303 can latch the gear 301. When the first latching member 302 or the second latching member 303 latches the gear 301, the rotating block 304 stops rotating, the first latching member 302 and the second latching member 303 reset, and then the gear 301 can continue to work normally. Under the blowing of strong wind, the impeller 201 continues to drive the rotating block 304 to rotate, and the first latching member 302 or the second latching member 303 pushes to the predetermined position, and so on, until the impeller 201 is limited and no longer rotates.

[0029] Example 2 Reference Figures 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the telescopic component 102 includes a first spring 102a, a connecting post 102b, a connecting block 102c, and a cavity 102d. The cavity 102d is opened on the side of the housing 101. The first spring 102a is fixedly installed in the cavity 102d. The connecting post 102b is fixedly installed at the other end of the first spring 102a. The connecting block 102c is fixedly installed at the other end of the connecting post 102b. When the user puts the sign into the housing 101, the connecting post 102b drives the connecting block 102c to move outward. At the same time, the first spring 102a stores force. After the sign is put into the housing 101, the first spring 102a rebounds under force and clamps the sign, so that the indicator can work.

[0031] Preferably, the rotating component 202 includes a first connecting post 202a and a rotating outer shell 202b. The rotating outer shell 202b is fixedly disposed at the rear end of the housing 101. The first connecting post 202a is rotatably disposed through the rotating outer shell 202b and is rotatably disposed on the side of the rear end of the housing 101. The rotating outer shell 202b is used to protect the internal parts to prevent them from being damaged in the harsh working environment of an open-pit mine.

[0032] Preferably, the oscillating component 203 includes a first oscillating block 203a, a second connecting post 203b, and a second oscillating block 203c. The first oscillating block 203a is rotatably disposed outside the first connecting post 202a and rotatably disposed on the upper end of the impeller 201. The second connecting post 203b is fixedly disposed on the other end of the first oscillating block 203a. The second oscillating block 203c is rotatably disposed outside the second connecting post 203b. When the wind blows the impeller 201 to rotate, it drives the first oscillating block 203a to rotate. At the same time, the first oscillating block 203a drives the second oscillating block 203c to rotate through the second connecting post 203b. The rotation of the second oscillating block 203c drives the extension component 205 to move left and right through the buckle component 204 to achieve the purpose of scraping the card surface.

[0033] Preferably, the fastener 204 includes a slot 204a, a block 204b, and an extension block 204c. The extension block 204c is slidably disposed inside the second swing block 203c. The slot is formed on the surface of the second swing block 203c. The slot 204a is formed on the surface of the extension block 204c. The block 204b is fastened and engaged inside one of the slots 204a. The extension block 204c and the second swing block 203c are engaged through the slot 204a and the block 204b to accommodate the installation and placement of different sized cards. When the card is placed inside the housing 101, the second swing block 203c and the extension block 204c are telescopically adjusted and then fixed by the block 204b to prevent the extension 205 from failing to work.

[0034] Furthermore, the extension 205 includes an inner scraper 205a, an outer scraper 205b, and a third connecting post 205c. The third connecting post 205c is fixedly disposed on the side of the extension block 204c. The inner scraper 205a is fixedly disposed on the side of the third connecting post 205c. The outer scraper 205b is slidably disposed on the outer side of the bottom end of the inner scraper 205a. The inner scraper 205a is tightly fitted with the upper end of the housing 101, and the outer scraper 205b is tightly fitted with the lower end of the housing 101. The inner scraper 205a and the outer scraper 205b are automatically adjusted according to the size of the card face placed in the housing 101. The inner scraper 205a is fixedly connected to the extension block 204c through the third connecting post 205c so that the impeller 201 rotates to drive the inner scraper 205a and the outer scraper 205b to move left and right.

[0035] In use, when the user places the card face into the housing 101, the connecting post 102b drives the connecting block 102c to move outward. Simultaneously, the first spring 102a stores force. After the card face is placed into the housing 101, the first spring 102a rebounds, clamping the card face, thus enabling the indicator to function. When the wind blows and the impeller 201 rotates, it drives the first swing block 203a to rotate. Simultaneously, the first swing block 203a, through the second connecting post 203b, drives the second swing block 203c to rotate. Block 203c rotates (the extension block 204c and the second swing block 203c are connected by a slot 204a and a block 204b to accommodate the installation of different sized cards), and the inner scraper 205a and the outer scraper 205b are automatically adjusted according to the size of the card placed in the housing 101. The inner scraper 205a is fixedly connected to the extension block 204c by the third connecting column 205c so that the impeller 201 rotates to drive the inner scraper 205a and the outer scraper 205b to move left and right.

[0036] Example 3 Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, the first fastening element 302 includes a second spring 302a, a first straightening block 302b, and a first locking block 302c. The first straightening block 302b is fixedly disposed on the left end of the rotating block 304. One end of the second spring 302a is fixedly disposed on the bottom end of the first straightening block 302b. The first locking block 302c is fixedly disposed on the top end of the second spring 302a. A cavity is formed inside the first locking block 302c. The first fastening element 302 also includes a third spring 302d, a second straightening block 302e, and a second locking block 302f. The second straightening block 302e is fixedly disposed on the upper end of the rotating block 304. The third spring 302d is fixedly disposed on the top end of the rotating block 304. The first locking block 302c is fixedly positioned to the right of the second straightening block 302e, and the second locking block 302f is fixedly positioned to the other end of the third spring 302d. The second locking block 302f has an internal cavity. When the wind blows, the impeller 201 rotates, causing the rotating block 304 to rotate. The rotation of the rotating block 304 causes the first locking block 302c to move upwards (302c has multiple internal cavities, allowing it to be pushed to different positions depending on the wind speed). When the wind is weak, the rotating block 304 causes the first locking block 302c to move upwards, and then the first locking block 302c is pressed against the second locking block 302d within the gap between the blades of the rotating block 304. When spring 302a is pulled back, it prevents it from pressing against the inner cavity of the second locking block 302f (the top of the first locking block 302c engages with the cavity of the second locking block 302f in a wedge shape). Therefore, the second locking block 302f will not move to the right, and its right-end rack will not engage with gear 301. The impeller 201 can then rotate normally, allowing the card surface to be scraped. When the airflow is too strong, the rotating block 304 rotates rapidly, and the first locking block 302c moves upward. Although the first locking block 302c is pulled by the second spring 302a, it will still be pushed against the second locking block 302f by the rotating block 304, thus preventing the second locking block 302f from moving to the right. The locking gear 301 obstructs the rotation of the impeller 201, causing the impeller 201 to stop rotating. The first locking block 302c is reset by the tension of the second spring 302a, and the second locking block 302f is also reset. The gear 301 is no longer obstructed, and the impeller 201 can continue to be driven by the wind. The impeller 201 continues to rotate, which in turn drives the first locking block 302c to push the second locking block 302f to the right, locking the gear 301 again. This puts the impeller 201 in a stopped state to prevent the rotating component 200 from moving too fast due to excessive wind force and damage.

[0038] Furthermore, the second fastening component 303 includes a fourth spring 303a, a third straightening block 303b, and a third locking block 303c. The third straightening block 303b is fixedly disposed at the bottom end of the rotating block 304, the fourth spring 303a is fixedly disposed on the right side of the third straightening block 303b, and the third locking block 303c is fixedly disposed at the other end of the fourth spring 303a. The third locking block 303c has a cavity inside. The second fastening component 303 also includes a fifth spring 303d, a fourth straightening block 303e, and a fourth locking block 303f. The fourth straightening block 303e is fixedly disposed on the side of the third straightening block 303b, the fifth spring 303d is fixedly disposed on the upper end of the fourth straightening block 303e, and the fourth locking block 303f is fixedly disposed on the upper end of the fifth spring 303d. The fourth locking block 303f has a cavity inside. When the wind blows the impeller 201 in the opposite direction, it drives the third locking block 303c to move to the right (while pressing down the first locking block 302c, but the first locking block 302c is unaffected). Similarly, when the air volume is small, when the third locking block 303c is pushed to the right, it will be pulled back by the fourth spring 303a in the gap between the fan blades of the rotating block 304, and it will not be able to push the fourth locking block 303f, so that the fourth locking block 303f will not move upward to engage the gear 301. When the air volume is large, the third locking block 303c is pushed to the fourth locking block 303f (the top of the third locking block 303c and the inside of the fourth locking block 303f are wedge-shaped), so that the fourth locking block 303f can move upward and the rack and pinion at its top engages the gear 301, thus stopping the impeller 201 from working.

[0039] In use, when the wind blows, the impeller 201 rotates, causing the rotating block 304 to rotate. The rotation of the rotating block 304 causes the first locking block 302c to move upward. When the wind force is not strong, the rotating block 304 causes the first locking block 302c to move upward. Then, in the gap between the blades of the rotating block 304, the first locking block 302c is pulled back by the second spring 302a, so that it will not push against the inner cavity of the second locking block 302f. Therefore, the second locking block 302f will not move to the right, and thus the rack at its right end will not move. With the locking gear 301 engaged, the impeller 201 can rotate normally, allowing the card surface to be scraped. When the airflow is too strong, the rotating block 304 rotates rapidly, and the first locking block 302c moves upward. Although the first locking block 302c is pulled by the second spring 302a, it is still pushed by the rotating block 304 to the second locking block 302f. Thus, the second locking block 302f engages the gear 301, thereby hindering the rotation of the impeller 201. The impeller 201 stops rotating, and the first locking block 302c is reset by the pull of the second spring 302a. Block 302f is reset, gear 301 is no longer obstructed, and impeller 201 can continue to be driven by the wind. Impeller 201 continues to rotate, which in turn drives the first locking block 302c to push the second locking block 302f to the right, locking gear 301 again, thus putting impeller 201 in a stopped state. When the wind blows impeller 201 in the opposite direction, it drives the third locking block 303c to the right. Similarly, when the wind volume is low, when the third locking block 303c is pushed to the right, it rotates... In the gap between the fan blades of block 304, the fourth spring 303a pulls it back, preventing it from pushing the fourth locking block 303f. This prevents the fourth locking block 303f from moving upward to engage the gear 301. When the airflow is large, the third locking block 303c is pushed to the fourth locking block 303f, allowing the fourth locking block 303f to move upward and engage the rack and pinion gear 301 at its top. Similarly, this stops the impeller 201 from working, preventing the impeller 201 from rotating too fast due to excessive airflow, which could cause the rotating component 200 to move too fast and be damaged.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
