[0004] Although the above device solves the problem of long-term working state affecting the load performance of the driving equipment, it still has the following shortcomings:

[0005] When the lifting box and the manhole cover are located in the manhole, dust and a small amount of sand on the airport ground are easily accumulated in the gap between the manhole cover and the top of the manhole. Therefore, when the manhole cover rises with the lifting box, the dust and sand that enter the gap will fall into the manhole, causing inconvenience. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an aviation ground well with a protective structure, which is convenient for preventing dust and sand from the ground well equipment.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an aviation manhole with a protective structure, comprising a manhole body, a lifting base connected to the manhole body, and a manhole cover connected to the top of the lifting base. A U-shaped box is fixedly connected to the inner wall of the opening of the manhole body, and the other side of the U-shaped box is located close to the lifting base and is slidably connected to the outer wall of the lifting base. A dust cover is connected to the outer side of the lifting base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model arranges a fixed U-shaped box between the lifting base and the opening of the well body. When dust, impurities and fine sand and gravel penetrate into the gap, the manhole cover rises and opens, and the dust, impurities and fine sand and gravel fall along the inclined edge of the well body opening and enter the U-shaped box. Since the U-shaped box is tightly attached to the lower part of the inclined edge of the well body opening, it can effectively receive the dust, impurities and fine sand and gravel, and effectively prevent the dust, impurities and fine sand and gravel from falling directly into the well body and the lifting base, thereby achieving a dust-proof effect. The utility model has a simple structure, is easy to operate and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] like Figures 1 to 8 As shown, an aviation ground manhole with a protective structure includes a manhole body 1, a lifting base 3 connected to the manhole body 1, and a manhole cover 2 connected to the top of the lifting base 3. A U-shaped box 5 is fixedly connected to the inner wall of the opening of the manhole body 1. The other side of the U-shaped box 5 is located close to the lifting base 3 and is slidably connected to the outer wall of the lifting base 3. A dust cover 4 is connected to the outer side of the lifting base 3.

[0025] like Figure 1 As shown, the aviation ground shaft with a protective structure in the present invention is similar to an existing hydraulic cylinder type lifting ground shaft structure used in an airport. For example, the patent with announcement number CN213620296U discloses a hydraulic cylinder type lifting ground shaft used in an airport. The main improvement of the present invention is to facilitate dust and sand prevention of the ground shaft equipment. Figures 1 to 5 As shown, when the aviation ground manhole with a protective structure in the utility model is in use, when the lifting base 3, the box body and the manhole cover 2 are located in the manhole body 1, dust, impurities and fine sand and gravel will enter from the connecting gap between the manhole cover 2 and the manhole body 1. After the dust, impurities and fine sand and gravel penetrate into the gap, as the manhole cover 2 rises and opens, the dust, impurities and fine sand and gravel will fall along the inclined edge of the opening of the manhole body 1 and enter the U-shaped box 5. Since the U-shaped box 5 is closely attached to the lower side of the inclined edge of the opening of the manhole body 1, the dust, impurities and fine sand and gravel can be effectively received, and the dust, impurities and fine sand and gravel can be effectively prevented from falling directly into the manhole body 1 and the lifting base 3, thereby achieving a dust-proof effect.

[0026] The dust cover 4 is located on the top surface of the lifting base 3. When the lifting base 3 rises, the dust cover 4 rises with it. When the position of the lifting base 3 is fixed, the dust cover 4 has a certain height, which effectively blocks the dust, impurities and fine sand and gravel carried by the wind. At the same time, the outer wall of the dust cover 4 is located on one side of the U-shaped box 5, so that the lifting base 3 and the opening of the well body 1 are blocked by the dust cover 4 and received by the U-shaped box 5, preventing dust, impurities and fine sand and gravel from entering the well body 1.

[0027] like Figure 3 、 Figure 5 、 Figure 6 and Figure 8 As shown, the U-shaped box 5 is connected to the take-out box 6, and the bottom surface of the inner part of the take-out box 6 is connected to an electrostatic adsorption film.

[0028] Specifically, in order to facilitate cleaning of the dust in the U-shaped box 5, the removal box 6 can be taken out from the U-shaped box 5 to clean the dust. An electrostatic adsorption film is placed in the removal box 6 to effectively adsorb the dust.

[0029] like Figure 5 and Figure 8 As shown, the tops of the two vertical plates of the U-shaped box 5 are fixedly connected with an inner buffer plate 10 and an outer buffer plate 11 respectively. The outer side of the top of the outer buffer plate 11 is inclined. The outer buffer plate 11 is located on the side away from the lifting base 3, and the top surface of the inner buffer plate 10 is in contact with the bottom surface of the manhole cover 2.

[0030] Specifically, the arrangement of the inner buffer plate 10 and the outer buffer plate 11 can play a buffering role when the manhole cover 2 is lowered and fits therewith, thereby preventing the U-shaped box 5 from directly contacting the manhole cover 2 and causing wear and impact problems.

[0031] By setting the top of the outer buffer plate 11 in an inclined state, it can play a certain role in guiding dust and sand, making it easier for them to enter the removal box 6.

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the dust cover 4 is a retractable structure, and the top is connected to a hanging structure connected to the bottom surface of the manhole cover 2.

[0033] Specifically, the dust cover 4 can be a retractable accordion cover, a dust-proof membrane installed with a frame, or a bellows structure, so that the dust cover 4 can be stretched to protect the entire well equipment.

[0034] like Figure 3 and Figure 7As shown, the hanging structure includes hooks 9, and hooks 9 are fixedly connected to both sides of the top of the dust cover 4. The two hooks 9 are symmetrically arranged. Connecting blocks 7 are fixedly connected to both sides of the bottom surface of the manhole cover 2, and the outer wall of the connecting block 7 is fixedly connected to a hanging rod 8 corresponding to the position of the hook 9.

[0035] Specifically, when the underground well equipment is raised but the power supply is not connected, the hook 9 on the top of the dust cover 4 can be hung with the hanging rod 8, so that the dust cover 4 can be set between the lifting base 3 and the well cover 2 to play a protective role. When the power supply needs to be plugged in, the dust cover 4 can be removed, which makes it convenient to use the power supply or air-conditioning pipe in the box.

[0036] The dust cover 4 here should be installed without hindering the installation and use of the structure of the underground well equipment itself, so as to ensure the normal use of the underground well equipment.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
