Technical Field
[0001] This utility model relates to the field of mining equipment technology, specifically to a smart screen that is both a mine-grade encapsulated and intrinsically safe display. Background Technology
[0002] In high-risk industries such as mining, safety in production is always of paramount importance. With the advancement of intelligent transformation in mines, the demand for electronic devices such as displays in special environments has surged. Traditional displays are unable to meet the requirements of complex underground mining environments, such as flammable and explosive, humid, and dusty conditions. They also have significant shortcomings in terms of explosion-proof, dustproof, and anti-interference capabilities. Mining-grade encapsulated and intrinsically safe displays have emerged to meet this need. They are specifically designed for underground environments and have advantages such as explosion-proof, high brightness, and low power consumption.
[0003] The encapsulation process enables displays to meet the requirements for use in explosive atmospheres. By sealing and encapsulating relevant components, it prevents sparks or high temperatures from causing explosions. The intrinsically safe design further ensures that the equipment will not ignite the environment under specified conditions. Through circuit suppression and multiple protections, energy, sparks, and heat are strictly controlled. However, in complex environments such as mines, displays are easily subjected to external impacts. Existing protection methods mostly rely on more rigid shells to form protection, but the inner layer is only protected by a single component such as cushioning cotton. Moreover, the dust in mines is heavy, and after long-term use, the screen is prone to dust accumulation. Once a large amount of dust accumulates, it can easily cause the screen to be obstructed. Therefore, a mine-grade encapsulated and intrinsically safe smart screen is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a smart screen that is both a mine-grade encapsulation and intrinsically safe display, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart screen for mining-grade encapsulation and intrinsically safe display, comprising: a protective shell, a display screen fixedly connected to the interior of the protective shell via multiple connecting pillars, an air pump fixedly connected to the inner bottom wall of the protective shell, an air outlet of the air pump connected to an air supply pipe, a transparent protective bladder fixedly connected to one side of the inner wall of the protective shell, a sliding structure connected to the exterior of the transparent protective bladder, an air outlet of the air supply pipe connected to the transparent protective bladder, the transparent protective bladder fitting against the display side of the display screen, and a dust removal structure integrally formed on the top of the transparent protective bladder, the dust removal structure being used to continuously spray gas to the exterior of the transparent protective bladder to clean the mining dust adhering to the surface of the transparent protective bladder.

[0008] As a further preferred embodiment of this technical solution: upper and lower protective bladders are integrally formed above and below the transparent protective bladder. The upper and lower protective bladders are connected to the transparent protective bladder. The upper and lower protective bladders are used to expand together with the transparent protective bladder when it expands, and extend into the space between the display screen and the upper and lower positions of the protective shell through expansion.
[0009] As a further preferred embodiment of this technical solution: the transparent protective bladder has multiple side protective bladders integrally formed on its exterior, the multiple side protective bladders are connected to the transparent protective bladder, and the multiple side protective bladders are spaced apart between the multiple connecting posts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, the synergistic effect of the transparent protective bladder, the upper and lower protective bladders, and the side protective bladders enables all-round protection from the front, upper and lower sides, and both sides of the display screen. After expansion, the transparent protective bladder fits tightly against the display surface of the display screen, effectively resisting external physical impacts and collisions. The upper and lower protective bladders fill the gap between the display screen and the protective shell, while the side protective bladders fill the space between the connecting column and the display screen, preventing dust and debris from entering the display screen installation area and ensuring the safe and stable operation of the display screen in the complex and harsh mining environment.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] Example
[0028] Please see Figures 1-8 This utility model provides a technical solution: a smart screen for mining encapsulation and intrinsically safe display, comprising: a protective shell 1, a display screen 2 fixedly connected to the inside of the protective shell 1 by multiple connecting pillars 11, an air pump 3 fixedly connected to the inner bottom wall of the protective shell 1, an air supply pipe 4 connected to the air outlet of the air pump 3, a transparent protective bladder 5 fixedly connected to one side of the inner wall of the protective shell 1, a sliding structure connected to the outside of the transparent protective bladder 5, the air outlet of the air supply pipe 4 connected to the transparent protective bladder 5, the transparent protective bladder 5 being attached to the display side of the display screen 2, and a dust removal structure integrally formed on the top of the transparent protective bladder 5, the dust removal structure being used to continuously spray gas to the outside of the transparent protective bladder 5 to clean the mineral dust adhering to the surface of the transparent protective bladder 5.
[0029] In this embodiment, specifically: during use, after the protective shell 1 is installed in the designated position, the air pump 3 can be started to continuously supply gas into the air supply pipe 4. While the gas is continuously supplied into the air supply pipe 4, gas can be supplied into the transparent protective bladder 5 through the air supply pipe 4. When the transparent protective bladder 5 is continuously supplied with gas, the transparent protective bladder 5 will expand. When the transparent protective bladder 5 expands, it will be guided by the sliding structure to fully expand the transparent protective bladder 5. When the transparent protective bladder 5 is fully expanded, it will protect the screen of the display screen 2, and the normal display of the display screen 2 will not be affected when the protection is formed.
[0030] In this embodiment, specifically: an elastic pull rope 9 is fixedly connected to one side of the T-shaped slider 7, and the side of the elastic pull rope 9 away from the T-shaped slider 7 is fixedly connected to the inner wall of the protective shell 1. When the gas inside the transparent protective bladder 5 is completely discharged and no more air is introduced, the elastic pull rope 9 stretched by the T-shaped slider 7 will cause the T-shaped slider 7 and the transparent protective bladder 5 to gradually retract to the unexpanded state.
[0031] like Figures 2-6 As shown, in order to prevent a large amount of dust from the mine from falling onto the surface of the transparent protective bag 5, a dust removal structure is set up. The dust removal structure includes an air-blowing expansion bag 8, which is integrally formed on the side of the transparent protective bag 5 away from the display screen 2. Multiple micro-holes are opened at the bottom of the air-blowing expansion bag 8.
[0032] In this embodiment, specifically: when the transparent protective capsule 5 is fully expanded, gas is continuously supplied to the interior of the transparent protective capsule 5 by the air pump 3, and the continuously supplied gas is ejected outward through the micropores on the outside of the transparent protective capsule 5. When gas is continuously ejected outward through the micropores, the situation of dust falling and adhering to the surface of the transparent protective capsule 5 can be reduced, thus reducing the adhesion of dust and avoiding affecting the display effect of the display screen 2.
[0033] like Figures 2-6 As shown, the sliding structure includes two T-shaped sliders 7, which are fixedly connected to the side of the transparent protective capsule 5 away from the display screen 2. The protective shell 1 has two T-shaped grooves 6 on the side close to the transparent protective capsule 5, and the T-shaped sliders 7 are slidably connected to the inside of the T-shaped grooves 6.
[0034] In this embodiment, specifically: when the transparent protective capsule 5 expands, the side of the transparent protective capsule 5 that is not fixed will continue to move outward. During the movement, the T-shaped slider 7 slides inside the T-shaped groove 6, thereby guiding the expansion direction of the transparent protective capsule 5. By guiding the expansion direction of the transparent protective capsule 5, the transparent protective capsule 5 can block the display screen 2 after it is fully expanded.
[0035] like Figures 3-6 As shown, upper and lower protective bladders 10 are integrally formed on the top and bottom of the transparent protective bladder 5. The upper and lower protective bladders 10 are connected to the transparent protective bladder 5. The upper and lower protective bladders 10 are used to expand together with the transparent protective bladder 5 when it expands, and extend into the space between the display screen 2 and the protective shell 1 at the top and bottom positions through expansion.
[0036] In this embodiment, specifically: during use, as the transparent protective bladder 5 continues to expand, the gas inside the transparent protective bladder 5 will be diverted to the interior of the upper and lower protective bladders 10, thereby causing the upper and lower protective bladders 10 to also expand. When the upper and lower protective bladders 10 also expand, they can protect the upper and lower sides of the display screen 2.
[0037] like Figures 3-5As shown, the transparent protective capsule 5 has multiple side protective capsules 12 integrally formed on its exterior. The multiple side protective capsules 12 are connected to the transparent protective capsule 5 and are spaced apart between multiple connecting posts 11.
[0038] In this embodiment, specifically: by setting multiple side protective bladders 12, they can be filled between multiple connecting pillars 11 and the display screen 2, thereby protecting both sides of the display screen 2.
[0039] In this embodiment, specifically: the side protective bladder 12 has multiple air vents 17 on the side near the display screen 2, and the display screen 2 has an integrally formed air guide strip 20. Through the setting of the air vents 17, the gas inside the side protective bladder 12 can be discharged and blown towards the back of the display screen 2 to dissipate heat on the back of the display screen 2, such as the motherboard. The inner wall of the air vent 17 has an integrally formed electromagnet 18 and a magnetic block 19. In the normal state, the magnetic block 19 will attract the electromagnet 18 through its own magnetism. The electromagnet 18 is made of ferrous material in the normal state and will be attracted by the magnetic block 19. When heat dissipation is required, the electromagnet 18 is energized. After the coil inside the electromagnet 18 is energized, it will form a magnet with the electromagnet 18 as a whole, thereby generating a repulsive force with the magnetic block 19. Under the condition of generating a repulsive force, the air vents 17 are opened, thereby spraying out the gas through the air vents 17, which, together with the air guide strip 20, forms a better heat dissipation effect.
[0040] like Figure 5 As shown, considering that the side of the protective shell 1 is very easily touched in the mine, and that a large impact force can cause the external impact force to be transmitted to the display screen 2, the side protective bladder 12 is a double-layer bladder. The outer bladder is connected to the transparent protective bladder 5, and the inner bladders of multiple side protective bladders 12 are connected by multiple connecting pipes 13. The inner bladder of the side protective bladder 12 is filled with a non-Newtonian liquid 14. The non-Newtonian liquid 14 is filled into the inner bladder space of the side protective bladder 12 through the connecting pipes 13. When a large impact force hits the side of the protective shell 1, the non-Newtonian liquid 14 will harden. The hardening caused by the non-Newtonian liquid 14 will form an isolation effect again, reducing the situation where a large impact force directly hits the outside of the display screen 2.
[0041] In this embodiment, specifically: two handles 15 are fixedly connected to the protective shell 1, and two fixed seats 16 are fixedly connected to the bottom of the protective shell 1. The two handles 15 on the protective shell 1 provide a point of leverage for the staff to move the protective shell 1. The fixed seats 16 are provided to assist in the placement of the protective shell 1. The fixed seats 16 have mounting holes inside, through which the protective shell 1 and the display screen 2 can be installed in the designated position.
[0042] Working principle: After the protective shell 1 is installed in the designated position, the air pump 3 starts working and continuously supplies gas into the air supply pipe 4. The gas enters the transparent protective bladder 5 through the air supply pipe 4, increasing the internal pressure and causing it to expand. During the expansion process, the two T-shaped sliders 7 fixedly connected to the side away from the display screen 2 slide within the two T-shaped grooves 6 opened on the inner wall of the protective shell 1 to guide the expansion direction, ensuring that the transparent protective bladder 5 is fully expanded and fits against the display side of the display screen 2, forming protection for the screen of the display screen 2 without affecting normal display. At the same time, the upper and lower parts of the transparent protective bladder 5 are integrated. The upper and lower protective bladders 10 are connected to the transparent protective bladder 5. When the transparent protective bladder 5 expands, the internal gas is diverted to the upper and lower protective bladders 10, causing them to expand together and extend into the space between the display screen 2 and the upper and lower positions of the protective shell 1 to protect the upper and lower sides of the display screen 2. Multiple side protective bladders 12 integrally formed on the outside of the transparent protective bladder 5 are connected to the transparent protective bladder 5 and are spaced apart between multiple connecting posts 11. When the transparent protective bladder 5 expands, the side protective bladders 12 also expand and fill the space between the multiple connecting posts 11 and the display screen 2 to protect the sides of the display screen 2.
[0043] The transparent protective bag 5 is integrally formed with an air-inflating bag 8 on the side away from the display screen 2. Multiple micro-holes are opened at the bottom. When the transparent protective bag 5 is fully inflated, the air pump 3 continuously delivers gas through the micro-holes to reduce dust falling and adhering to the surface of the transparent protective bag 5, thus affecting the display effect of the display screen 2.
[0044] The side protective bladder 12 has multiple air vents 17 on the side near the display screen 2. The inner wall of the air vent 17 is integrally formed with an electromagnet 18 and a magnetic block 19. Under normal conditions, the magnetic block 19 attracts the electromagnet 18 through its own magnetism, keeping the air vent 17 in a closed state. When heat dissipation is required, the electromagnet 18 is energized. After the coil inside the electromagnet 18 is energized, it forms a magnetism with the electromagnet 18 as a whole and generates a repulsive force with the magnetic block 19, thereby opening the air vent 17. The gas inside the side protective bladder 12 is discharged through the air vents 17 and blown towards the back of the display screen 2. Together with the air guide strip 20 integrally formed on the outside of the display screen 2, it forms a good heat dissipation effect.
[0045] The side protective bladder 12 is a double-layer bladder. The outer bladder is connected to the transparent protective bladder 5. The inner bladders of multiple side protective bladders 12 are connected by multiple connecting tubes 13 and the inner bladders are filled with non-Newtonian liquid 14. When the side of the protective shell 1 is subjected to a large impact force, the non-Newtonian liquid 14 will harden to form an isolation effect to reduce the situation where the large impact force directly impacts the outside of the display screen 2.
[0046] An elastic pull rope 9 is fixedly connected to one side of the T-shaped slider 7. The side of the elastic pull rope 9 away from the T-shaped slider 7 is fixedly connected to the inner wall of the protective shell 1. When the gas inside the transparent protective bladder 5 is completely discharged and no more gas is introduced, the elastic pull rope 9 stretched by the T-shaped slider 7 will drive the T-shaped slider 7 and the transparent protective bladder 5 to gradually retract to the unexpanded state. Two handles 15 are fixedly connected to the protective shell 1 to facilitate the staff to provide a point of leverage to move the protective shell 1.
[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
