BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 1 This is a schematic diagram of the overall structure of the out-of-well switch device of the utility model;

[0013] Attached Figure 2 It is a structural schematic diagram of the chassis;

[0014] Attached Figure 3 It is a schematic diagram of the structure of the transmission rod. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figures 1 to 3 The well valve off-well switch device comprises a transmission rod 1 and a rotating handle 2. The transmission rod 1 is a vertical rod body. The lower end of the transmission rod 1 is provided with a claw-shaped piece, which can be inserted into the gap of the valve hand wheel. The upper end of the transmission rod 1 is provided with a handle hole 3. The shape of the handle hole 3 is consistent with the shape of the rotating handle 2, so that the rotating handle 2 can be inserted into the handle hole 3. Figure 1 As shown in the figure, after the rotating handle 2 is inserted into the handle hole 3, the rotating handle 2 is rotated, and the claw-shaped part is driven to rotate through the transmission rod 1, so that the claw-shaped part can turn the valve handwheel. Due to the transmission rod 1, when opening or closing the valve in the well, the worker does not need to go down into the well, thereby avoiding the risk of personal injury. Due to the rotating handle 2, it is more labor-saving when turning the valve handwheel.

[0017] As attached Figure 1 and 2 As shown in the figure, the claw-type member includes a chassis 4, which is fixedly connected to the lower end of the transmission rod 1, and a plurality of sub-claw bodies 5 are arranged circumferentially on the chassis 4. Preferably, the number of the sub-claw bodies 5 is three, and the three sub-claw bodies 5 are arranged at equal angles to adapt to the shape of the valve handwheel.

[0018] The chassis 4 is provided with a plurality of adjustment slots 6, and the sub-claw body 5 is movably arranged in the adjustment slot 6, so that the position of the sub-claw body 5 in the adjustment slot 6 is adjustable. When the sub-claw body 5 moves in the adjustment slot 6, the size of the jaw opening of the claw-shaped part is changed to adapt to the size of different valve hand wheels.

[0019] As attached Figure 1 As shown in the figure, the sub-claw body 5 is composed of a screw rod 7 and a nut 8. The screw rod 7 is inserted into the adjustment groove 6 from top to bottom, and the lower ends of the plurality of screw rods 7 cooperate to form a claw-shaped structure. The nut 8 is threadedly matched with the screw rod 7, and the nut 8 is rotated upward from the lower end of the screw rod 7 to clamp the screw rod 7 to the chassis 4, so that the position of the screw rod 7 in the adjustment groove 6 is fixed.

[0020] Specifically, the chassis 4 is a circular disk, the lower end of the transmission rod 1 is connected to the center of the chassis 4 , and the adjustment slot 6 is a long strip slot extending along the radial direction of the chassis 4 .

[0021] As attached Figure 2 In one embodiment shown in , a plurality of arc-shaped notches 9 are provided on the groove wall of the adjusting groove 6, and the plurality of arc-shaped notches 9 are arranged along the length direction of the adjusting groove 6. When the screw rod 7 is inserted into the adjusting groove 6, it is correspondingly stuck in the arc-shaped notch 9 to prevent the screw rod 7 from sliding in the adjusting groove 6. The shape of the arc-shaped notch 9 is consistent with the shape of the screw rod 7, and the screw rod 7 can be stuck at a fixed position in the adjusting groove 6 through the arc-shaped notch 9. When the screw rod 7 and the nut 8 are not completely clamped on the chassis 4, the position of the screw rod 7 in the adjusting groove 6 will not change.

[0022] The transmission rod 1 is provided with a plurality of handle holes 3 arranged vertically, and the rotating handle 2 can be inserted into different handle holes 3 to change the relative height between the rotating handle 2 and the claw-shaped member to adapt to the depth of different valve wells.

[0023] When the utility model is in operation, the worker first adjusts the position of the screw rod 7 in the adjustment groove 6 according to the size of the valve hand wheel, and then clamps the screw rod 7 in the adjustment groove 6 with the nut 8, then holds the upper end of the transmission rod 1, aligns it with the valve hand wheel, and extends the screw rod 7 into the gap of the valve hand wheel, and then inserts the rotating handle 2 into the appropriate handle hole 3 on the transmission rod 1. Then, when the worker rotates the rotating handle 2, the transmission rod 1 and the claw-shaped piece can be used to open and close the valve hand wheel, thereby avoiding the risk of personal injury when the worker goes down to the well. In addition, the utility model can also be used for the opening and closing of some ground elevated pipeline valves to avoid the risk of people falling from high altitude.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
