Embodiment one:
when the outdoor environment is rainy or sunny, as shown in fig. 2, the controller controls the telescopic rod 23 to start, and as the telescopic rod 23 is fixedly connected with the inner side of the shielding cloth 21, the telescopic rod 23 drives the shielding cloth 21 to extend outwards from the first notch 2, the shielding cloth 21 has elasticity, the shielding cloth 21 is made of rubber, the rubber is thermoplastic elastomer, the thermoplastic elastomer has the characteristics of high elasticity, aging resistance, high temperature resistance and the like of the traditional cross-linked vulcanized rubber, as shown in fig. 4, under the pushing of the telescopic rod 23, the shielding cloth 21 is unfolded above the machine body 1 to form a rectangle, the shielding cloth 21 is in a tight state, the width of the shielding cloth 21 at the moment is larger than the width of the liquid crystal screen 11, and the projection area of the shielding cloth 21 in the vertical direction covers the liquid crystal screen 11, so that the shielding cloth 21 blocks rainwater and sunlight from radiating onto the liquid crystal screen 11, the aging speed of the liquid crystal screen 11 is slowed down due to the rainwater and sunlight, and the service life of the floor-type intelligent large liquid crystal screen is prolonged; as shown in fig. 1, a cushion block 24 is fixedly connected to the bottom of the machine body 1, the cushion block 24 is made of an anti-corrosion metal material, such as a stainless steel alloy material, the cushion block 24 is fixedly connected with the ground through nails, and the height of the floor-type intelligent liquid crystal large screen is increased through the cushion block 24 so as to reduce water accumulation on the road surface in rainy days, so that the bottom of the floor-type intelligent liquid crystal large screen is immersed in the water accumulation, and the inside of the floor-type intelligent liquid crystal large screen is damaged;
The movable plate 22 is rotatably connected with the inner wall of the first notch 2, a torsion spring is arranged at the rotating part, the telescopic rod 23 pushes the movable plate 22 to rotate and drives the shielding cloth 21 to extend outwards, as shown in fig. 4, the telescopic rod 23 divides the surface of the shielding cloth 21 into an upper surface and a lower surface, the bottom of the movable plate 22 is contacted with the surface of the shielding cloth 21, the cross section of the bottom of the movable plate 22 is triangular, and the inclined part of the triangle is far away from one side of the first notch 2; the shielding cloth 21 is in the rain shielding and sun shading process, the sundries possibly fall on the upper surface of the shielding cloth 21, so that the controller controls the telescopic rod 23 to drive the shielding cloth 21 to retract into the first notch 2 at night and in the absence of rain, in the process, the sundries with large particles automatically fall under the action of gravity, the torsion spring enables the bottom of the movable plate 22 to generate pressure on the shielding cloth 21, so that the bottom of the movable plate 22 scrapes the sundries with small particles, the phenomenon that the sundries remain on the surface of the shielding cloth 21 is reduced, when the shielding cloth 21 returns to the first notch 2 under the traction of the telescopic rod 23, the movable plate 22 closes the port of the first notch 2 under the action of gravity and the torsion spring, the movable plate 22 isolates the shielding cloth 21 from the external environment, and the phenomenon that the shielding cloth 21 is exposed to the outside for a long time and the external environment damages the surface of the shielding cloth 21 is caused.
As an embodiment of the present invention, as shown in fig. 5, the cross-section of the end portion of the telescopic rod 23 contacting the shielding cloth 21 is semicircular, so as to reduce the damage of the end portion of the telescopic rod 23 to the inner side surface of the shielding cloth 21;

When the outdoor environment is rainy for a long time, the bottom of the machine body 1 is fixedly connected with the top of the extension block 41, and the extension block 41 is in sliding sealing connection with the inner wall of the top of the cavity 4, as shown in fig. 9, the bottom of the extension block 41 is uniformly distributed with expansion bags 42, the expansion bags 42 contain water absorbing materials such as bentonite or super absorbent resin, and the bentonite or super absorbent resin can absorb water with hundreds to thousands of times of the self weight and can repeatedly release and absorb water; the long-term raining causes the road surface to generate accumulated water, the accumulated water enters the cushion block 24 through the round hole 44 and is in contact with the expansion bag 42, the volume of the expansion bag 42 increases after water absorption, the expansion bag 42 after water absorption moves upwards in the cavity 4 through extruding the extension block 41, so that the extension block 41 drives the machine body 1 to move upwards, the height of the machine body 1 on the road surface is improved, the situation that the bottom of the machine body 1 is submerged in the accumulated water is reduced, and the weight of the expansion bag 42 increases after water absorption, so that the stability of the cushion block 24 in the accumulated water can be improved; after the accumulated water is removed, the expansion bag 42 in the cushion block 24 is taken out and replaced by rotating the cover plate 43, and the wet expansion bag 42 can be recycled after being dried, so that the accumulated water is reduced to enter the machine body 1 through the expansion bag 42 and the extension block 41, and the fire disaster is caused by short circuit of the parts of the machine body 1, so that the normal use of the landing intelligent liquid crystal large screen is affected.
As an embodiment of the present invention, as shown in fig. 10, the inner wall of the circular hole 44 is fixedly connected with a filter screen 441, and the filter screen 441 is made of a waterproof and corrosion-resistant material, for example, the filter screen 441 is made of a stainless steel material;
as shown in fig. 9, a limiting groove 45 is formed in the inner wall of the cavity 4, and the bottom side surface of the extension block 41 is slidably connected in the limiting groove 45, so as to improve the stability of the extension block 41 moving up and down in the cavity 4;
In the invention, impurities with large particles possibly exist in the ponding, along with fluctuation of water flow, the impurities enter the cavity 4 through the round holes 44, after the expansion bag 42 absorbs water and expands, the expansion bag 42 drives the impurities to contact with the inner wall of the cavity 4, if the impurities have sharp edges, such as stones, and the hardness of the inner wall of the cavity 4 is greater than that of the stones, the stones are greater than that of the expansion bag 42, under the action of mutual extrusion, the stones possibly scratch the expansion bag 42 to cause the expansion bag 42 to be broken, so that water absorbing materials in the expansion bag 42 diffuse and flow out of the cushion 24, as shown in fig. 10, a filter screen 441 is fixedly connected in the round holes 44, the situation that the impurities with large particles enter the cavity 4 to cause the expansion bag 42 to be broken is reduced, and the filter screen 441 adopts waterproof and corrosion-resistant materials, such as steel materials, so that the service life of the filter screen 441 is prolonged;
As shown in fig. 9, the inner walls of the two sides of the cavity 4 are provided with limit grooves 45, and the bottom side surfaces of the extension blocks 41 are connected in a sliding manner in the limit grooves 45, so that the sliding range of the extension blocks 41 in the cavity 4 is limited by the limit grooves 45, the phenomenon that the extension blocks 41 deviate in the cavity 4 is reduced, and the upward movement stability of the machine body 1 is improved; therefore, through the arrangement of the filter screen 441 and the limiting groove 45, the practicability of the cushion block 24 is further improved, and the strength of the cushion block 24 for protecting the floor-type intelligent liquid crystal large screen is enhanced.
