Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the guardrail device of the wellhead comprises a fixed ring 3, the fixed ring 3 is fixed on a well wall under a well lid, the diameter of the fixed ring 3 is slightly smaller than that of the well lid so as to facilitate installation of the fixed ring 3, the size of the fixed ring 3 is determined by different well mouths, telescopic guardrails 4 are fixedly connected to the upper surface of the fixed ring 3, the telescopic guardrails 4 are regularly distributed on the fixed ring 3, the number of the telescopic guardrails 4 is more than 5, the specific number is determined by the size of the fixed ring, 3 or 4 telescopic joints are arranged on each telescopic guardrail 4, the extended height of the telescopic guardrail 4 is 1m-1.5m, the telescopic guardrails 4 are connected through cross bars 9, the stability of the telescopic guardrail 4 on the fixed ring 3 is maintained, the top ends of the telescopic guardrails 4 are round-head type ends to prevent people from being scratched, and fluorescent coatings are arranged on the surfaces of the telescopic guardrails 4, the lower surface of the fixed ring 3 is fixedly connected with a pressure sensor 5, the output end of the pressure sensor 5 is connected with a pressure transmitter 6, the pressure transmitter 6 is connected with a microcomputer processor 7 through a signal line, the microcomputer processor 7 is connected with a power supply 2, the power supply 2 is connected with the telescopic guardrail 4 through an electric wire, a protective shell 8 is arranged outside the power supply 2, the power supply 2 is placed in the protective shell 8, and circuit faults caused by water inflow and other reasons of the power supply can be prevented; be equipped with switch 1 on protective housing 8, the usual state keeps switch 1 to be in the open mode, and when the problem appeared, device automatic operation, rise telescopic fence 4, when the well lid need be maintained and changed, closed switch 1, switch 1 is controlled by relevant staff.

The working principle is as follows: the control circuit diagram of the barrier device is shown in figure 4. When the well cover is covered on the well mouth, the weight of the well cover is transferred to the pressure sensor 5 below the fixing ring 3 through the fixing ring 3, the type number of the pressure sensor is OMEGA PXM309 series, the pressure sensor senses the pressure and transmits a signal to the microcomputer controller, the weight of the well cover is borne on the pressure sensor 5, and the telescopic guardrail 4 is in a contraction state at the moment; when the well lid of well head is stolen the back or is walked by the water-washed back, the well lid weight that bears disappears on the pressure sensor 5, the signal that pressure sensor 5 will gather is transferred into distinguishable signal transmission for microcomputer processor 7 through pressure transmitter 6, microcomputer processor 7 carries out the analysis processes back to the signal of collecting, will control flexible guardrail 4 automatic slow rising, the rising speed should not be too fast, flexible guardrail automatic rising relies on microcomputer processor 7 transmission signal to give flexible guardrail, then utilize the telescoping device to rise the guardrail, flexible guardrail contains the telescoping device, this device begins to operate after the received signal. The flexible guardrail 4 rises the back and will form the round guardrail around the well head, prevents that people or other objects from dropping to in the well to be equipped with fluorescent coating on the surface of flexible guardrail 4, can give out light at night, the pedestrian of being convenient for discerns flexible guardrail 4 in dark environment, this is this well head guardrail device's theory of operation.
