[0002] In the process of oil exploration, it is necessary to insert the probe into the underground geology to determine the underground oil reserves and the prospects for oil exploitation in the area. After the exploration work is completed, the staff manipulates the exploration equipment to raise and reset the probe. When the probe is reset, the probe is directly exposed to the air. When the exploration equipment needs to be transported, the probe is prone to collision with the vehicle body, which may cause the probe to be easily damaged. In response to the above problem, in the patent document with publication number CN217836651U, when the probe is moved upward and reset, the staff fits the second stainless steel protective shell with the first stainless steel protective shell so that the second stainless steel protective shell and the first stainless steel protective shell protect the probe, thereby avoiding collision of the probe during the transportation of the exploration equipment. However, when the first stainless steel protective shell and the second stainless steel protective shell are docked, the staff needs to use bolts to dock them, which is time-consuming and labor-intensive.

[0003] Therefore, it is necessary to provide a new oil production probe protective device to solve the above-mentioned technical problems. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 7 An embodiment of the utility model provides a petroleum production probe protection device, which includes a protection tube 1, an abutment ring disk 2 and a clamping assembly 4.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 7 A top cover 12 is fixedly installed on the top of the protective tube 1, and a rod hole 12a is provided on the top cover 12 for the probe connecting rod to slide outward, and an elastically arranged abutment ring disk 2 is installed in the protective tube 1. Specifically, installation grooves 1a are provided on the inner walls on both sides of the protective tube 1, and a sliding rod 21 is fixedly installed in each of the installation grooves 1a, and a spring 22 is connected in series on the sliding rod 21, and two convex plates are provided on the abutment ring disk 2, and the two convex plates are respectively inserted and sleeved on the two sliding rods 21 and slidably connected with the sliding rods 21, one end of the spring 22 is fixedly connected to the bottom wall of the installation groove 1a, and the other end of the spring 22 is fixedly connected to the lower surface of the convex plate.

[0028] It should be noted that: the protective tube 1 is fixedly installed on the shell of the probe reset area, and the connecting rod on the probe is kept passing through the top cover 12 and the abutting ring disk 2, so that the probe is located below the protective tube 1. When the staff manipulates the mining probe to move and reset out of the wellhead, the probe is cleaned by the impact equipment. When the cleaning is completed, the mining probe is manipulated to move and reset. At this time, the top shell of the probe pushes the abutting ring disk 2 and drives the abutting ring disk 2 to slide up along the sliding rod 21, so that the spring 22 is compressed, and the set abutting ring disk 2 can effectively alleviate the impact force between the probe and the top cover 12 when it slides into the protective tube 1 (such as the attached Figure 7 shown);

[0029] Among them, a plurality of annularly distributed elastic raised steel bars 11 are fixedly embedded in the outer tube wall of the protective tube 1. The arranged elastic raised steel bars 11 can reduce the impact on the protective tube 1, thereby effectively protecting the probe located in the protective tube 1.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 7 A vertically arranged tooth plate 3 is installed on the abutting ring disc 2, and the tooth plate 3 passes through the sliding hole 12b opened in the top cover 12 and extends out of the protective tube 1, and a plurality of locking holes 3a equidistantly distributed vertically are opened on the tooth plate 3, and a locking rod 31 is inserted into any of the locking holes 3a;

[0031] A clamping assembly 4 for clamping the probe connecting rod is mounted on the top cover 12, and the clamping assembly 4 includes a mounting frame 41, and the mounting frame 41 is provided with two groups and is symmetrically mounted on both sides of the ring opening of the abutting ring disk 2, and a rotatably connected lead screw 42 and a fixedly mounted limiting slide 43 are mounted between the two groups of the mounting frames 41, and two symmetrically distributed and threaded arc clamps 44 are installed on the lead screw 42. Specifically, the lead screw 42 is provided with two symmetrically distributed threaded sections with opposite thread directions, and each threaded section is threadedly connected with an arc clamp 44, and the other end of the arc clamp 44 is sleeved on the limiting slide 43 and is slidably connected to the limiting slide 43, and one end of the lead screw 42 is fixedly sleeved with a gear 45, and the gear 45 is meshedly connected with the toothed plate 3.

[0032] It should be noted that: when the engaging ring disk 2 slides up along the sliding rod 21, the tooth plate 3 slides up accordingly and drives the meshing connected gear 45 to rotate. Since the lead screw 42 is provided with two symmetrically distributed threaded sections with opposite thread directions, the arc clamps 44 distributed on both sides of the lead screw 42 slide towards each other. Therefore, when the probe completely slides into the protective tube 1, the two arc clamps 44 also complete the clamping of the top connecting rod of the probe. Subsequently, the locking rod 31 can be passed through the locking hole 3a closest to the upper surface of the top cover 12, so that the probe can be stored in the protective tube 1 for protection, avoiding the collision between the probe and the exploration equipment during transportation. At the same time, when the probe is stored in the protective tube 1, the clamping assembly 4 automatically completes the clamping without manual operation, which is simple and convenient.

[0033] The working principle of the oil production probe protection device provided by the utility model is as follows:

[0034] The protective tube 1 is fixedly installed on the shell of the probe reset area, and the connecting rod on the probe is kept to pass through the top cover 12 and the abutting ring disk 2, so that the probe is located below the protective tube 1. When the staff manipulates the mining probe to move and reset out of the wellhead, the probe is cleaned by the impact equipment. After the cleaning is completed, the mining probe is manipulated to move and reset. At this time, the top shell of the probe pushes the abutting ring disk 2 and drives the abutting ring disk 2 to slide up along the sliding rod 21, so that the spring 22 is compressed, and the abutting ring disk 2 can effectively alleviate the impact force between the probe and the top cover 12 when the probe slides into the protective tube 1.

[0035] When the engaging ring disk 2 slides up along the sliding rod 21, the tooth plate 3 slides up accordingly and drives the meshing gear 45 to rotate. Since the lead screw 42 is provided with two symmetrically distributed threaded sections with opposite thread directions, the arc clamps 44 distributed on both sides of the lead screw 42 slide towards each other. Therefore, when the probe completely slides into the protective tube 1, the two arc clamps 44 also complete the clamping of the top connecting rod of the probe. Subsequently, the locking rod 31 can be passed through the locking hole 3a closest to the upper surface of the top cover 12, so that the probe can be stored in the protective tube 1 for protection, avoiding the collision between the probe and the exploration equipment during transportation. At the same time, when the probe is stored in the protective tube 1, the clamping assembly 4 automatically completes the clamping without manual operation, which is simple and convenient.
