[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A display device for building cost, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it comprises a main body 1, a glass plate 2 matched with the main body 1 is arranged at one end thereof, and a pasting cavity 3 is opened between the main body 1 and the glass plate 2, chains 4 are movably connected to both sides of the main body 1, sprocket wheels 29 meshing with two groups of chains 4 are rotatably connected to the four corners of the main body 1, motors 28 are installed on both sides of the main body 1, and the output ends of the two groups of motors 28 are fixedly connected to the rotating shafts of the two groups of sprocket wheels 29 respectively;

[0033] A connecting frame 5 is fixed to the outside of the two groups of chains 4, and the two groups of connecting frames 5 and the two groups of chains 4 are fixedly connected by a connecting rod 6. A lifting slider 7 is elastically connected to the outside of the connecting frame 5. The insides of the two groups of lifting sliders 7 are both rotatably connected with a connecting shaft 8. A cleaning brush roller 9 located at one end of the glass plate 2 is fixed between the two groups of connecting shafts 8. A first gear 11 is fixed to the outside of the two groups of connecting shafts 8. A first rack 12 meshing with the first gear 11 is fixed to both sides of one end of the main body 1.

[0034] Both sides of the main body 1 are slidably connected with support plates 13, and a booster cylinder 14 is fixed inside the support plate 13. The booster cylinder 14 and the connecting shaft 8 are connected through two groups of connecting pipes 15, wherein the two groups of connecting shafts 8 are provided with cavities 10 inside, and the cleaning brush roller 9 is provided with a hollow cavity connected to the cavity 10, and liquid slip rings 21 are provided outside the two groups of connecting shafts 8, and the liquid slip rings 21 are respectively connected to the cavity 10 and the connecting pipe 15, and a water storage cavity 25 is provided inside the main body 1. The bottom of both sides of one end of the main body 1 is provided with a water inlet head 23 connected to the water storage chamber 25, and one end of the booster cylinder 14 is connected with a connecting cylinder 22. The two groups of connecting cylinders 22 and the two groups of water inlet heads 23 are respectively connected by two groups of corrugated hoses 24. The booster cylinder 14 is rotatably connected with a transmission rod 16, and a booster impeller 20 located inside the booster cylinder 14 is fixed on the outside of the transmission rod 16. A second gear 17 is provided on the outside of the transmission rod 16. The two sides of the main body 1 are fixed with a second gear connected to the second gear. 17 meshes with the second rack 18, and the transmission rod 16 and the second gear 17 are rotatably connected through the one-way bearing 19. When the cleaning brush roller 9 descends, the second gear 17 meshes with the second rack 18 to drive the transmission rod 16 and the boost impeller 20 to rotate inside the boost cylinder 14, and then the rotating boost impeller 20 drives the water source inside the water storage chamber 25 into the inside of the boost cylinder 14 through the water inlet head 23, the corrugated hose 24 and the connecting cylinder 22 in sequence. Then, under the action of the boost impeller 20, the water flow enters the liquid slip ring 21 through the two groups of connecting pipes 15, and then enters the hollow cavity inside the cleaning brush roller 9 through the cavity 10 inside the two groups of connecting shafts 8. Since not only brushes are evenly arranged on the surface of the cleaning brush roller 9, but also water spray holes are evenly opened, it can be seen from the above that the cleaning brush roller 9 rotates while descending, and sprays water while rotating, so that the cleaning effect on the glass plate 2 is better, making the surface of the glass plate cleaner and clearer.

[0035] See also Figure 6 The connecting frame 5 and the lifting slider 7 are elastically connected by a spring frame 27, and a spring is arranged inside the lifting slider 7. By setting the above structure, the present invention can always make the two sets of lifting sliders 7 close to the main body 1 under the action of the spring frame 27, and then make the cleaning brush roller 9 close to the glass plate 2, so that the cleaning brush roller 9 has a better cleaning effect on the surface of the glass plate 2.

[0036] See also Figure 2 and Figure 3 A water injection hole matching the water storage chamber 25 is provided at the middle position of the top of the main body 1, and a sealing plug 26 matching the water storage chamber 25 is provided inside the water injection hole. The present invention sets the above structure, wherein the water injection hole is convenient for replenishing water inside the water storage chamber 25, and the sealing plug 26 plays a role in sealing and closing the water storage chamber 25.

[0037] See also Figure 1 , Figure 2 and Figure 8 A protective cover 30 located on the outside of the cleaning brush roller 9 is fixed on the outside of the two sets of lifting sliders 7, and the top and bottom ends of the protective cover 30 are in contact with the surface of the glass plate 2, and mounting frames 31 are fixed on both sides of one end of the main body 1. The present invention is provided with the above structure, wherein the protective cover 30 can not only block the liquid sprayed from the cleaning brush roller 9 to prevent splashing to the outside, but also the top and bottom ends of the protective cover 30 can scrape the glass plate 2, thereby preventing the cleaning liquid or water stains from adhering to the surface of the glass plate 2 after cleaning, and the mounting frame 31 can fix the present invention as a whole on an external frame or wall.

[0038] A method for displaying construction cost, the process of which comprises the following steps:

[0039] S1: Pasting the construction cost report: firstly, paste the construction cost report inside the pasting cavity so that the glass covers and protects it;

[0040] S2: Glass plate cleaning: The surface of the glass plate is cleaned and washed by a cleaning brush roller that reciprocates and rises and rotates synchronously and sprays water;

[0041] S3: Replenishment of cleaning liquid: According to the number of times the glass plate is cleaned, water is regularly replenished inside the water storage chamber so that there will be no shortage of water when the glass plate is cleaned next time.

[0042] The working principle of the present invention is as follows: when in use, the power is turned on to fix the main body 1 with the external frame through two groups of mounting frames 31, the construction cost report is pasted inside the pasting cavity 3, and then covered and protected by the glass plate 2, wherein the glass plate 2 and the main body 1 are sealed and connected in a snap-fit ​​manner and can be disassembled, and then the water source or cleaning liquid is regularly added to the water storage cavity 25 through the sealing plug 26, wherein the two groups of chains 4 on both sides of the main body 1 are respectively connected by two groups of sprockets 29 meshing therewith, and one group of sprockets 29 is driven by a motor 28 to provide power to the two groups of chains 4;

[0043] After the glass plate 2 is used for a period of time and dust is accumulated on the surface, the chain 4 is firstly driven to drive the lifting slider 7 to move downward from top to bottom through the connecting frame 5 and the connecting rod 6, and then the two sets of lifting sliders 7 drive the cleaning brush roller 9 to clean the surface of the glass plate 2 through the two sets of connecting shafts 8. When the cleaning brush roller 9 descends, the first gear 11 engages with the first rack 12 to drive the cleaning brush roller 9 to rotate, thereby cleaning the dust on the surface of the glass plate 2 more quickly.

[0044] And while the cleaning brush roller 9 is descending, the second gear 17 meshes with the second rack 18 to drive the transmission rod 16 and the boost impeller 20 to rotate inside the boost cylinder 14, and then the rotating boost impeller 20 drives the water source inside the water storage chamber 25 into the inside of the boost cylinder 14 through the water inlet head 23, the corrugated hose 24 and the connecting cylinder 22 in sequence, and then the water flow enters the liquid slip ring 21 through the two groups of connecting pipes 15 under the action of the boost impeller 20, and then enters the hollow cavity inside the cleaning brush roller 9 through the cavity 10 inside the two groups of connecting shafts 8. And because the surface of the cleaning brush roller 9 is not only evenly provided with brushes, but also evenly opened with water spray holes, it can be known from the above that the cleaning brush roller 9 rotates while descending, and sprays water while rotating, so that the cleaning effect on the glass plate 2 is better, making the surface of the glass plate cleaner and clearer;

[0045] Furthermore, when the cleaning brush roller 9 descends, the protective cover 30 also descends simultaneously, wherein the protective cover 30 can not only block the liquid sprayed by the cleaning brush roller 9 to prevent it from splashing to the outside, but also the top and bottom ends of the protective cover 30 can scrape the glass plate 2, thereby preventing the cleaning liquid or water stains from adhering to the surface of the cleaned glass plate 2;

[0046] Furthermore, after the cleaning brush roller 9 cleans the glass plate 2 from top to bottom, the chain 4 drives the cleaning brush roller 9 to rise and reset, and because a one-way bearing 19 is provided between the second gear 17 and the transmission rod 16, when the second gear 17 is reversed, the transmission rod 16 is idle, and thus the booster impeller 20 is not driven to rotate in the opposite direction. That is to say, when the cleaning brush roller 9 rises, the inside of the cleaning brush roller 9 will not spray water or cleaning liquid to the outside. At this time, the rising cleaning brush roller 9 only rotates to clean the surface of the glass plate 2, thereby saving water or cleaning liquid.

[0047] Specifically, through the forward and reverse rotation of the sprocket 29, the cleaning brush roller 9 can be reciprocated and lifted for cleaning. According to the degree of dirtiness of the glass plate 2, the cleaning brush roller 9 can be adapted to perform multiple reciprocating cleanings. The overall cleaning process of the glass plate 2 is more uniform and thorough, and the problem of increased labor intensity caused by the need for personnel to clean is effectively avoided.

[0048] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
