DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] See also Figure 1-3 The present invention provides an embodiment of a push-pull type rotating ball pitcher, comprising: a rotating ball pitcher body 100, a rotating handle 300 is provided on the upper side of the rotating ball pitcher body 100, a pitching port 101 is provided on one side of the upper end surface of the rotating ball pitcher body 100, and an insertion port 10101 is provided on the other side of the upper end surface of the rotating ball pitcher body 100;

[0023] Also includes:

[0024] The first inner cavity 102 is installed on one side of the rotating ball pitcher body 100. The second inner cavity 10201 is provided on the other side of the rotating ball pitcher body 100. A rotating shaft 200 is provided on the outside of the rotating ball pitcher body 100. One end of the rotating shaft 200 is connected to the rotating ball pitcher body 100 for push-pull and forward-backward operations and for positional movement with the rotating ball pitcher body 100. A movable end 203 is provided inside the first inner cavity 102. One end of the rotating shaft 200 is rotatably connected to the movable end 203 via a bolt connection end 2001 with an embedded bolt.

[0025] Example 2

[0026] See also Figure 1 and Figure 2 The upper and lower sides of the inner wall of the second inner cavity 10201 are both provided with anti-falling protrusion blocks 105, and there are two anti-falling protrusion blocks 105, and the two anti-falling protrusion blocks 105 are welded to the upper and lower sides of the inner wall of the second inner cavity 10201.

[0027] The provision of the anti-falling protrusion 105 can effectively prevent the internal movable end head 203 from being stripped during the movement process, thereby affecting the operation of the rotary sealing mechanism 103 .

[0028] See also Figure 1 and Figure 2 The lower end surface of the rotating handle 300 is provided with a connecting and installing insertion piece 301, the interior of the second inner cavity 10201 is provided with a rotating sealing mechanism 103, the interior of the upper end surface of the rotating sealing mechanism 103 is provided with a mounting groove 10302, the lower end of the connecting and installing insertion piece 301 is installed in the interior of the mounting groove 10302 in an embedded manner, the interior of the rotating sealing mechanism 103 is provided with a hollow ball cavity 10301, and the interior of the hollow ball cavity 10301 is provided with a rubber ball 104. The first inner cavity 102 and the second inner cavity 10201 are arranged to communicate with each other. The rotating sealing mechanism 103 is connected to the inner wall of the rotating ball pitcher body 100 through an elastic floating support 106. Handle rod bodies 201 are provided on both sides of the outer wall of the other end of the rotating shaft 200, and there are two handle rod bodies 201. The two handle rod bodies 201 are welded to both sides of the outer wall of the other end of the rotating shaft 200.

[0029] See also Figure 1 、 Figure 2 and Figure 3 A soft rubber layer 20301 is provided on one side of the movable end head 203 , and the soft rubber layer 20301 is hot-melt connected to one side of the movable end head 203 .

[0030] The provided soft rubber layer 20301 can effectively weaken the impact force of component contact.

[0031] Working principle: The main body 100 of the rotary ball dispenser is installed between the wellhead tee and the back pressure valve. When the ball needs to be dispensed, there is no need to stop the well. The rotary sealing mechanism 103 is rotated -90 degrees by rotating the handle 300 to temporarily close the middle flow port. The liquid flows into the oil pipeline from the annular space outside the rubber ball. At this time, one end of the rotating shaft 200 is installed inside the first inner cavity 102, and the end head 2001 is stably connected to the movable end head 203 through the bolt connection end 2001. The rubber ball 104 is inserted into the first cavity through the ball dispensing port 101. Inside the inner cavity 102, one end of the rotating shaft 200 is pushed into the first inner cavity 102, so that the rubber ball 104 is pushed into the hollow ball cavity 10302 inside the rotary seal mechanism 103 as the end of the rotating shaft 200 is pushed deeper. After the rubber ball 104 enters the hollow ball cavity 10302, the rotary seal mechanism 103 is rotated +90° by rotating the handle 300. Due to the impact of the liquid, the rubber ball 104 flows into the oil pipeline along with the oil. The device can also be installed on the oil pipeline, using the same principle as above, ultimately achieving the purpose of clearing wax from the oil pipeline.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
