Vertical shaft protective sleeve

Abstract

The invention discloses a vertical shaft protective sleeve. The vertical shaft protective sleeve comprises a safe sleeve, a rotating control rotary shaft is arranged in the safe sleeve, in addition, afirst rotating gear is arranged inside the safe sleeve, the control rotary shaft drives the first gear to rotate, a rotating protective outer lid is arranged on the safe sleeve, and controlled to beopened and closed through rotation of the first gear, a circular-ring-shaped fourth rotating groove is formed in the safe sleeve, a rotating gear ring is arranged in the fourth rotating groove, a first supporting sliding groove of a circle is formed in the safe sleeve and communicated correspondingly with the fourth rotating groove, and a protective support which swings in the sleeve and the groove is arranged in the first supporting sliding groove. A vertical shaft can be protected through the protective outer lid to prevent falling, and the protective outer lid can be further controlled to be opened and closed through the control rotary shaft.

Description

technical field [0001] The invention relates to a shaft protection device, in particular to a shaft protection sleeve, in particular to a shaft protection sleeve capable of protecting a shaft and preventing falling into the shaft. Background technique [0002] As the need for agricultural irrigation further leads to an increase in the demand for water, it is necessary to drill vertical wells in the land to ensure the normal supply of water resources. Due to the excessive number of vertical wells, it is inevitable to cause There will be abandoned shafts, and most of the current shafts are only covered by ordinary protective measures, so as to avoid the problem of falling into the shaft and causing danger. Although the use of ordinary protective measures can provide certain safety precautions, the time With the passage of time, it is inevitable that there will be problems that the protective measures are not in place, which has caused a certain threat to the life safety of ped...

[0002] As the need for agricultural irrigation further leads to an increase in the demand for water, it is necessary to drill vertical wells in the land to ensure the normal supply of water resources. Due to the excessive number of vertical wells, it is inevitable to cause There will be abandoned shafts, and most of the current shafts are only covered by ordinary protective measures, so as to avoid the problem of falling into the shaft and causing danger. Although the use of ordinary protective measures can provide certain safety precautions, the time With the passage of time, it is inevitable that there will be problems with insufficient protective measures, which pose a certain threat to the life safety of pedestrians.
