[0019] The present utility model will be described in detail below with reference to the drawings and specific embodiments.

[0020] A new type of shaft automatic cage door device of the present utility model, as Figure 1 and 2 shown, includes:

[0021] A new type of shaft automatic cage door device, characterized in that it includes a cage 1, and a cage door is arranged on one side of the cage 1; at the top of the cage 1 and on the side where the cage door is located, a horizontal screw 6 is arranged. The screw 6 straddles the cage door, and a motor 5 is connected to each of its left and right ends.

[0022] The cage door includes: a plurality of hollow round steel pipes 8 and two steel wire ropes 7; among which:

[0023] The plurality of hollow round steel pipes 8 are arranged at intervals up and down. Each hollow round steel pipe 8 is horizontally arranged, and its left and right ends extend to the left and right sides of the cage 1;

[0024] The plurality of hollow round steel pipes 8 are sequentially connected and fixed by two steel wire ropes 7. The two steel wire ropes 7 are arranged left and right, and the upper ends of each steel wire rope 7 are fixedly connected to the screw 6;

[0025] Two motors are used to drive the rotation of the screw (6) to drive the cage door to rise or fall through the steel wire rope (7). It is used to drive the rotation of the screw 6 to drive the cage door to rise or fall through the steel wire rope 7.

[0026] After the plurality of hollow round steel pipes 8 are connected vertically, the uppermost hollow round steel pipe 8 is located more than half of the height of the cage 1 and does not reach the top.

[0027] RFID tag boxes 2 are installed on both the left and right sides of the cage 1. A rectifying circuit is arranged in the RFID tag box 2. The rectifying circuit includes a receiving antenna 2-1, a matching microstrip line 2-2, and a Schottky diode 2-3 connected in sequence; the other end of the Schottky diode 2-3 is connected to a capacitor 2-4 and a resistor 2-5 connected in parallel. Both the capacitor 2-4 and the resistor 2-5 are arranged on the substrate 2-6, and the lead-out wires at both ends of the resistor 2-5 are voltage output terminals.

[0028] As Figure 3 shown, an inverter circuit box 4 is installed on both the left and right sides of the cage 1. An inverter circuit is arranged in the inverter circuit box 4. The inverter circuit includes a transformer 4-1, a transistor 4-2, and a potentiometer 4-3; both the transistor 4-2 and the potentiometer 4-3 are connected to the transformer 4-1;

[0029] The voltage input terminal of the inverter circuit is connected to the voltage output terminal in the rectifying circuit through a wire, and the voltage output terminal of the inverter circuit is connected to the voltage input terminal of the motor 5 through a wire 3.

[0030] At the upper part of the cage 1 and on the side of the cage door, a vertical hook 9 is provided. The vertical hook 9 is used to carry the hollow round steel pipe 8 and fix the rolling door.

[0031] The receiving antennas 2-1 in the rectifying circuits on both the left and right sides of the cage 1, the left side is responsible for lifting the rolling door, the right side is responsible for lowering the rolling door, and the connection method of the wire at the input end of the motor 5 on the left side is opposite to that of the wire at the input end of the motor 5 on the right side, realizing the forward and reverse rotation of the two motors 5.

[0032] When the rolling door curtain needs to be lifted at the wellhead or the bottom of the well, a radio frequency signal is transmitted through a radio frequency transmitter, and is signal-connected to the receiving antenna 2-1 of the left rectifying circuit. The radio frequency signal passes through the matching microstrip line 2-2, the Schottky diode 2-3, the resistor 2-5 and the capacitor 2-5, that is, the half-wave rectifying circuit. The matching microstrip line 2-2 realizes impedance matching and improves the rectifying efficiency of the rectifying circuit. The Schottky diode 2-3 converts the radio frequency signal into direct current electricity, and after passing through the resistor 2-5 and the capacitor 2-5, a direct current voltage is obtained. The direct current voltage is input to the inverter circuit 4, and through the transistor 4-2, the transformer 4-1 and the potentiometer 4-3, the transformer 4-1 outputs a high voltage to meet the usage requirements of the motor 5. The motor 5 rotates forward, drives the screw rod 6 to rotate, realizes the winding of the steel wire rope 7, and drives the hollow round steel pipe 8 to be lifted, realizing the lifting of the rolling door curtain.

[0033] When the rolling door curtain needs to be lowered, a radio frequency signal is transmitted through a radio frequency transmitter, and is signal-connected to the receiving antenna 2-1 of the right rectifying circuit. The basic principle is the same. Since the wire connection at the input end of the motor 5 on the left is opposite to the wire connection at the input end of the motor 5 on the right, the rotation direction of the motor 5 on the right is opposite, and thus the lowering of the rolling door curtain is realized.

[0034] At the upper part of the cage 1 and on the side of the cage door, a vertical hook 9 is provided, so that when a failure occurs during the up and down movement of the cage in the well, the rolling door curtain can be manually lifted, and the hollow round steel pipe 8 is hung in the vertical hook, which is convenient for personnel to enter and exit.
