Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The utility model provides a time-delay hydraulic structure, which can be seen in fig. 1 and comprises a cylinder body 100 and a partition 300, wherein the cylinder body 100 is provided with a driving channel, the partition 300 slides in the driving channel, and the time-delay sliding effect is realized after the partition is pushed by hydraulic pressure.

The partition 300 is slidably inserted into the driving channel to partition the driving channel into a first chamber and a second chamber. The oil is supplied into the oil filling port 120 by the oil supply means, and the partition 300 is pushed to slide in the driving passage by the hydraulic oil.
The partition 300 includes a sliding base 310 and an elastic telescopic rod 320, the sliding base 310 is slidably embedded in the driving passage, a flow guide hole 311 communicating the first chamber and the second chamber is formed in the sliding base 310, one end of the elastic telescopic rod 320 is installed in the sliding base 310, and the other end of the elastic telescopic rod abuts against and seals an opening of the flow guide hole 311 far away from the oil filling port 120.
For convenience of explaining the working principle of the embodiment, a cavity close to the oil filling port 120 is defined as a first cavity, a cavity far away from the oil filling port is defined as a second cavity, hydraulic oil is filled into the driving channel by using oil transportation equipment, the pressure in the first cavity close to the oil filling port 120 is increased, when the pressure difference between the first cavity and the second cavity is higher than a critical value borne by the elastic telescopic rod 320, the elastic telescopic rod 320 retracts, the hydraulic oil enters the second cavity through the flow guide hole 311, the partition 300 is further pushed to slide, and simultaneously, after the pressures of the first cavity and the second cavity are balanced, the flow guide hole 311 is closed again by the elastic telescopic rod 320. When the pressure in the first chamber rises again, so that the pressure difference between the first chamber and the second chamber is higher than the critical value of the elastic expansion rod 320, the hydraulic oil enters the second chamber again to push the separating member 300 to slide, and the separating member 300 can be pushed to slide repeatedly.
The present embodiment not only greatly reduces the operation difficulty of construction, but also greatly reduces the operation difficulty of construction, and at the same time, since the pressure difference between the first chamber and the second chamber reaches the critical value, the hydraulic oil can push the partition 300 to slide for a certain distance, the driving of the partition 300 by the oil transportation equipment is staged and delayed, and the existing hydraulic driving method can directly push the partition 300 to slide after the oil transportation equipment applies pressure to the partition 300.
In order to improve the sealing performance of the separator 300, a sealing groove 312 is formed on a contact surface of the sliding base 310 and the inner wall of the driving channel, and a sealing material is embedded in the sealing groove 312.
In a preferred embodiment, one end of the slide 310 is tapered to allow the slide 310 to more easily fit into the drive channel during installation.
