[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example 1, by Figure 1 The present invention relates to a height-adjustable underground valve protective housing device, comprising an underground valve body 1, and a protective mechanism 2 provided on the top of the underground valve body 1.

[0017] Specifically, by Figures 2-3 The protection mechanism 2 includes a protection cylinder 201 fixed to the top of the underground valve body 1. A lifting cylinder 202 is provided on the outer side of the protection cylinder 201. An opening 205 is provided at the top of the lifting cylinder 202. A cover plate 204 is hinged to the top of the lifting cylinder 202. A sealing ring 203 is fixedly connected to the bottom of the cover plate 204. The sealing ring 203 fits against the top of the lifting cylinder 202, and the cover plate 204 is positioned at the opening 205. The sealing ring 203 ensures the sealing between the cover plate 204 and the lifting cylinder 202, allowing the cover plate to... When normally closed, 204 provides full protection; when in operation, it can be opened. The bottom end of the lifting cylinder 202 is fixedly connected to the outer cylinder 2010. The inner side of the outer cylinder 2010 is provided with an internal thread 207, and the outer side of the protective cylinder 201 is provided with an external thread 2011. The external thread 2011 matches the internal thread 207. The outer cylinder 2010 is threaded onto the outer side of the protective cylinder 201 through the internal thread 207 and the external thread 2011. A limit ring 206 is fixedly sleeved on the outer side of the protective cylinder 201, and the outer cylinder 2010 is located below the limit ring 206. The operating mechanism is fully protected by the protective cylinder 201, the lifting cylinder 202, and the cover plate 204 to prevent corrosion of the operating mechanism and to prevent accidental contact or malicious damage. Since the outer cylinder 2010 is threaded onto the outside of the protective cylinder 201 through the internal thread 207 and the external thread 2011, the lifting cylinder 202 can be rotated to achieve longitudinal movement and complete the adjustment of the height of the lifting cylinder 202.

[0018] Specifically, by Figures 4-5As shown, an outer ring 208 is fixedly sleeved on the outside of the protective cylinder 201. A bellows 209 is fixedly connected to the top of the outer ring 208. A top ring 2012 is fixedly connected to the top of the bellows 209. A sealing ring 2013 is fixedly connected to the top of the top ring 2012. The sealing ring 2013 is attached to the bottom of the outer cylinder 2010. Multiple vertical cylinders 2014, all located inside the bellows 209, are fixedly connected at equal angles to the top of the outer ring 208. Multiple columns 2015 are fixedly connected at equal angles to the bottom of the top ring 2012. Each column 2015 is movably sleeved inside the respective vertical cylinder 2014. A spring 2016 is fixedly connected between the vertical cylinder 2014 and the top ring 2012. The spring 2016 is sleeved on the outside of the column 2015. Through the cooperation between the vertical cylinder 2014, the column 2015, and the spring 2016, the sealing ring 2013 is kept in close contact with the outer cylinder 2010 under the elastic force of each spring 2016. At the same time, the bellows 209 expands and contracts accordingly, thereby ensuring the sealing between the outer cylinder 2010 and the protective cylinder 201 and effectively preventing rainwater from seeping in.

[0019] Working principle: First, rotate the lifting cylinder 202, which drives the outer cylinder 2010 to rotate outside the protective cylinder 201. Since the internal thread 207 and the external thread 2011 are compatible, the outer cylinder 2010 moves longitudinally when rotating, which in turn drives the lifting cylinder 202 to move longitudinally. This allows the height of the lifting cylinder 202 to be adjusted as needed. At the same time, the protective cylinder 201 and the lifting cylinder 202 shield and protect the operating mechanism of the underground valve body 1, thus preventing the operating mechanism from rusting.
