[0021] Combine Figure 1 As shown, the utility model provides a deep well valve opener and closer, including a downhole fixed frame 1, a rotating shaft 2 and a rotating disk 3. One end of the rotating shaft 2 in the axial direction is used to extend into the deep well 10 and be connected to the valve switch 20. The other end of the rotating shaft 2 in the axial direction is used to extend from the inlet of the deep well 10 and be connected to the rotating disk 3. The diameter of the rotating disk 3 is larger than the diameter of the rotating shaft 2. The rotating shaft 2 and the rotating disk 3 are coaxially arranged. One end of the downhole fixed frame 1 is used to be fixed on the side wall of the deep well 10, and the other end is sleeved on the rotating shaft 2 and is rotatably connected to the rotating shaft 2.

[0022] Specifically, the rotating shaft 2 is vertical, and the two ends of the rotating shaft 2 in the axial direction are the upper end and the lower end of the rotating shaft 2. One end of the downhole fixed frame 1 is installed on the side wall of the deep well 10 by bolts or pins, and the other end of the downhole fixed frame 1 is located directly above the valve switch 20 and is provided with a sleeve or a bearing seat or a through hole or an iron wire. Taking the end of the downhole fixed frame 1 located directly above the valve switch 20 as an example, the lower end of the rotating shaft 2 is connected to the valve switch 20 after passing through the through hole. The downhole fixed frame 1 limits the radial movement of the rotating shaft 2 located in the deep well 10 through the through hole to ensure that the connection between the rotating shaft 2 and the valve switch 20 is stable. Then the upper end of the rotating shaft 2 extends from the wellhead of the deep well 10 and is connected to the turntable 3. The diameter of the turntable 3 is set larger than the diameter of the rotating shaft 2, and the turntable 3 can provide a hand-held grasping position. When it is necessary to open the valve at the bottom of the deep well 10, the operator can stand at the wellhead of the deep well 10 and manually rotate the turntable 3 to drive the rotation of the shaft 2. With the help of the downhole fixed frame 1 to limit the rotation shaft 2, it can be ensured that the shaft 2 will not tilt and only rotate to drive the valve switch 20 to rotate. The closing or opening of the valve at the bottom of the deep well 10 can be achieved on the well, so that the operator no longer needs to go down to the bottom of the deep well 10 to perform the valve opening or closing operation.

[0023] The cam 2 is connected to the bottom of the well 10 by the spring 2 and the spring 2 is connected to the top of the well 10 by the spring 2.

[0024] Optionally, combined Figure 1 As shown, the rotating shaft 2 includes a first connecting shaft 21 and a second connecting shaft 22. One axial end of the first connecting shaft 21 is used to connect with the valve switch 20, and the other end is rotatably connected to the downhole fixed frame 1. One axial end of the second connecting shaft 22 is connected to the turntable 3, and the other end is detachably connected to the first connecting shaft 21.

[0025] Specifically, the rotating shaft 2 is composed of a plurality of detachably connected connecting shafts, and the number of connecting shafts is temporarily two, namely the first connecting shaft 21 and the second connecting shaft 22. The first connecting shaft 21 is located below the second connecting shaft 22, and the lower end of the first connecting shaft 21 is connected to the valve switch 20. The upper end of the first connecting shaft 21 can be connected to the lower end of the second connecting shaft 22 through a sleeve or a coupling, and the upper end of the first connecting shaft 21 is rotatably connected to the downhole fixed support 1, and the upper end of the second connecting shaft 22 extends from the deep well 10 and is connected to the turntable 3. The lower end of the second connecting shaft 22 is connected to the upper end of the first connecting shaft 21. When in use, the lower end of the first connecting shaft 21 is pre-connected to the valve switch 20, and the upper end of the first connecting shaft 21 is pre-connected to the turntable 3. The downhole fixed frame 1 is rotated and connected, and then the second connecting shaft 22 is connected to the turntable 3. When the valve switch 20 needs to be opened or closed, the second connecting shaft 22 is extended into the deep well 10, and the lower end of the second connecting shaft 22 is connected to the upper end of the first connecting shaft 21 through the shaft connection structure. The second connecting shaft 22 can drive the first connecting shaft 21 to rotate to realize the opening or closing of the valve switch 20. Then, after the operation is completed, the second connecting shaft 22 can be removed from the first connecting shaft 21 separately to carry out the opening or closing operation of the valve switch 20 at the bottom of other deep wells 10. At the same time, it can also avoid the second connecting shaft 22 being placed at the operation site after the operation is completed to ensure the cleanliness of the operation site environment.

[0026] Optionally, combined Figure 1 As shown, a polygonal positioning groove is provided at one end of the first connecting shaft 21 facing the second connecting shaft 22 , and a polygonal positioning block is provided at one end of the second connecting shaft 22 facing the first connecting shaft 21 , and the polygonal positioning block is engaged with the polygonal positioning groove.

[0027] Specifically, the upper end of the first connecting shaft 21 can be set as a hexagonal positioning groove, and correspondingly, the lower end of the second connecting shaft 22 is set as a hexagonal positioning block. When in use, the hexagonal positioning block is inserted into the hexagonal positioning groove to realize the clamping between the first connecting shaft 21 and the second connecting shaft 22, so that the rotation of the first connecting shaft 21 realizes the rotation of the second connecting shaft 22.

[0028] In this way, a polygonal positioning groove is provided at one end of the first connecting shaft 21 facing the second connecting shaft 22, and a polygonal positioning block is provided at one end of the second connecting shaft 22 facing the first connecting shaft 21. The polygonal positioning block is engaged with the polygonal positioning groove, which can significantly simplify the connection method between the first connecting shaft 21 and the second connecting shaft 22, reduce the use of additional shaft connection structures, and reduce the cost of use.

[0029] Optionally, combined Figure 1 As shown, a clamping structure is provided at one end of the first connecting shaft 21 away from the second connecting shaft 22 , and the clamping structure is used to clamp with the valve switch 20 .

[0030] Specifically, the clamping structure can be a clamp, a clamping slot, or other structures. For example, the clamping slot is provided at the lower end of the first connecting shaft 21. During installation, the first connecting shaft 21 is clamped onto the valve switch 20 via the clamping slot. This not only achieves a detachable connection between the first connecting shaft 21 and the valve switch 20, but also supports the first connecting shaft 21, and can work together with the downhole fixed frame 1 to prevent the first connecting shaft 21 from tilting. When it is necessary to replace the valve inside the deep well 10, the first connecting shaft 21 can be separated from the valve, rather than replaced together with the valve, to facilitate valve replacement.

[0031] In this way, a clamping structure is provided at one end of the first connecting shaft 21 away from the second connecting shaft 22, and the clamping structure is used to clamp with the valve switch 20. The first connecting shaft 21 can be separated from the valve switch 20 as needed to ensure that the first connecting shaft 21 is an independent structure, so that the first connecting shaft 21 can be connected to different valve switches 20, thereby improving the convenience of use of the first connecting shaft 21 and reducing the cost of use.

[0032] Optionally, combined Figure 1 As shown, the deep well valve opener and closer further includes an upper well fixing frame 4 , on which a positioning structure is provided. The positioning structure is sleeved on the second connecting shaft 22 and is rotatably connected to the second connecting shaft 22 .

[0033] Specifically, the well fixing frame 4 is a combined structure, a part of the well fixing frame 4 is used to be fixed on the wellhead, and the other part is used to install the positioning structure, which can be a sleeve or a hole structure. The positioning structure can be sleeved on the second connecting shaft 22 and rotatably connected to the second connecting shaft 22.

[0034] In this way, by means of the positioning structure provided on the above-ground fixed frame 4 being sleeved on the second connecting shaft 22 and being rotatably connected with the second connecting shaft 22, the positioning structure can limit the radial movement and offset of the second connecting shaft 22, thereby realizing the limitation of the second connecting shaft 22 and ensuring the stable use of the second connecting shaft 22.

[0035] Optionally, combined Figure 1 As shown, the well fixing frame 4 includes a base 41, a first connecting seat 42 and a second connecting seat 43. The base 41 is used to be fixed on the wellhead, the first connecting seat 42 is slidably connected to the base 41, and the second connecting seat 43 is slidably connected to the first connecting seat 42. A positioning structure is provided on the second connecting seat 43, and the sliding direction of the first connecting seat 42 is perpendicular to the sliding direction of the second connecting seat 43.

[0036] Specifically, the base 41 is fixed to the side wall of the wellhead when in use, and the length direction of the wellhead can be the sliding direction of the first connecting seat 42, and the sliding direction of the second connecting seat 43 can be the width direction of the wellhead. Through the sliding of the first connecting seat 42 and the second connecting seat 43, the position of the positioning structure can be adjusted, thereby realizing the adjustment of the position of the second connecting shaft 22, which can make the use of the second connecting shaft 22 more flexible. For example, when multiple valves are provided at the bottom of the deep well 10, each valve is connected to the first connecting shaft 21, then when opening or closing the valve switch 20 of different valves, the movement of the second connecting shaft 22 can be realized by sliding the first connecting seat 42 and the second connecting seat 43, which can realize the connection between the same second connecting shaft 22 and different first connecting shafts 21, and thus realize the opening or closing of different valves by the same second connecting shaft 22.

[0037] In this way, the base 41 is used to be fixed at the wellhead, the first connecting seat 42 is slidably connected to the base 41, the second connecting seat 43 is slidably connected to the first connecting seat 42, and a positioning structure is provided on the second connecting seat 43. The sliding direction of the first connecting seat 42 is perpendicular to the sliding direction of the second connecting seat 43. The sliding of the first connecting seat 42 and the second connecting seat 43 can be used to adjust the position of the positioning structure, and then the position of the second connecting shaft 22 connected to the positioning structure can be adjusted. In this way, when multiple first connecting shafts 21 are provided at the bottom of the deep well 10, the same second connecting shaft 22 can be used to open or close different valves.

[0038] Optionally, combined Figure 1 As shown, the first connecting shaft 21 is coated with paint.

[0039] Specifically, a grille is generally provided at the wellhead of the deep well 10, which is not completely sealed. After the valve switch 20 is opened or closed, the first connecting shaft 21 is always exposed to the external environment and is easily corroded by rainwater and the like.

[0040] In this way, the first connecting shaft 21 is coated with paint, which can improve the corrosion resistance of the first connecting shaft 21 and extend the service life of the first connecting shaft 21.

[0041] Optionally, combined Figure 1 As shown, the second connecting shaft 22 is configured as a hollow shaft.

[0042] Specifically, the upper and lower ends of the second connecting shaft 22 can be respectively provided with two connecting blocks, which are threadedly connected to the second connecting shaft 22, and one connecting block is connected to the turntable 3 by bolts, and the other connecting block is provided with a polygonal clamping block so that it can be clamped with the polygonal clamping groove on the first connecting shaft 21.

[0043] In this way, by configuring the second connecting shaft 22 as a hollow shaft, a lightweight design of the second connecting shaft 22 is achieved, thereby facilitating the transportation of the second connecting shaft 22 and reducing the labor intensity of operators.

[0044] Optionally, combined Figure 1 As shown, the deep well valve opener and closeer also includes a support rod, which is obliquely arranged below the downhole fixed frame 1, and one end of the support rod is connected to the downhole fixed frame 1, and the other end is used to connect to the side wall of the deep well 10.

[0045] Specifically, the downhole fixed frame 1 can be set as a T-shaped structure, and includes a first connecting rod fixed on the side wall of the deep well 10, a second connecting rod vertically connected to the first connecting rod, the second connecting rod extends horizontally to the top of the valve switch 20, and is rotatably connected to the first connecting shaft 21, the support rod is obliquely arranged below the second connecting rod, and one end of the support rod is connected to the side wall of the deep well 10 by a bolt or a pin, and the other end of the support rod is connected to the lower end of the second connecting rod. The geometric connection line of the support rod, the second connecting rod and the side wall of the deep well 10 constitutes a triangular structure, which ensures the structural strength of the second connecting rod to avoid the second connecting rod from breaking due to the inclination of the first connecting shaft 21.

[0046] In this way, the support rod is tilted and arranged below the downhole fixed frame 1, and one end of the support rod is connected to the downhole fixed frame 1, and the other end is used to connect to the side wall of the deep well 10. The support rod can support the downhole fixed frame 1 from below the downhole fixed frame 1, thereby ensuring the stability of the downhole fixed frame 1 inside the deep well 10.

[0047] Optionally, combined Figure 1 As shown, the turntable 3 is configured as a spoke structure.

[0048] Specifically, the turntable 3 can be configured with a three-spoke or five-spoke structure, so that the operator can grasp the rim of the turntable 3, making it easier for the operator to apply force. Thus, by configuring the turntable 3 as a spoke structure, not only can the turntable 3 be lightweight, but it can also be easily grasped by the operator.

[0049] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
