Description

Fishing tool for deep well pump

Technical Field

The utility model relates to a fishing tool, in particular to a fishing tool for a deep well pump.

Background

The existing deep well water pump salvage operation is completed by a drilling machine provided with a self-tapping drill bit, and mainly aims at the water pump salvage operation after a steel pipe water outlet pipe is broken. Rely on the pushing down and the rotation of self-tapping drill bit, be connected the back with cracked steel pipe mouth tapping, upwards propose the drilling rod and be connected with the water pipe of water pump, accomplish the water pump and salvage. The reality is that the service life of the steel pipe is influenced in many areas due to high saline-alkali content of underground water and high corrosivity to metal. In order to save cost, a part of users replace steel pipes with PVC pipes, and after the PVC pipes are used for a period of time, the PVC pipes can also be broken due to material aging, water pumping operation errors and the like. After current area is salvaged from the rig of tapping drill bit and will appear drill bit and PVC pipe connection, PVC pipe can be cracked when pushing down the rotation, unable tapping interlock, cracked PVC material sinks into the shaft bottom after, and the piece inhales the water pump when the water pump is taken water, also can lead to the water pump blade card to die and then damage water pump and motor. The existing fishing equipment can not only not fish the water well of PVC pipes, but also influence the later use of the water well after fishing.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a deep-well pump fishing tool which is simple in structure and process, a crane which is used for matched operation is more flexible and faster than a drilling machine in transition, and both a steel pipe and a PVC (polyvinyl chloride) water pipe can be fished by the tool.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:

the deep well pump fishing tool comprises a barrel body, wherein a penetrating shaft is arranged at the upper part of the barrel body, blades and a hanging ring are rotatably arranged on the penetrating shaft, and the blades are arranged on the left and right and partially extend out of the barrel body; when the barrel body extends into the water pipe to be lifted, the blades are locked with the water pipe.

The outer ends of the blades are tips.

The lower end of the barrel body is conical.

The blade is limited by a positioning pin.

According to the fishing tool for the deep well pump, the tool is hung into a broken water pipe through a steel wire rope, the fishing tool is fixed by utilizing the inner diameter change of a joint between the water pipe and the water pipe, and then the steel wire rope is lifted through a crane, so that the water pump with the bottom sunk and the connecting water pipe can be fished out. The tool is simple in structure and simple in process, a crane in matched operation is also flexible and quick in transition compared with a drilling machine, and the tool can be used for fishing no matter a steel pipe or a PVC (polyvinyl chloride) water pipe, so that more economical and comprehensive fishing process and tool are provided for fishing of a water well water pump.

Drawings

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

fig. 1 is a front view of the present invention.

FIG. 2 is a front sectional view of the tub of the present invention.

Fig. 3 is a front view of a blade according to the utility model.

Fig. 4 is a front view of the suspension ring of the present invention.

Fig. 5 is a schematic structural diagram of the present invention.

In the figure: the device comprises a blade 1, a through shaft 2, a barrel body 3, a hanging ring 4 and a positioning pin 5.

Detailed Description

As shown in figures 1-5, the fishing tool for the deep well pump comprises a barrel body 3, and the barrel body 3 mainly plays a guiding role. The lower part of the barrel body 3 is conical, so that the barrel body can conveniently extend into a broken water pipe. A penetrating shaft 2 is transversely fixed at the upper part of the barrel body 3, two blades 1 are rotatably arranged on the penetrating shaft 2, and the two blades 1 are limited by a positioning pin 5. The two blades 1 are arranged left and right and partially extend out of the barrel body 3, the two blades 1 can rotate upwards, and are limited by the upper edge of the barrel body 3 when rotating downwards. In addition, a hanging ring 4 is also sleeved on the penetrating shaft 2, and the hanging ring 4 is connected with the steel wire rope at the later stage and is hung and conveyed by a crane.

During assembly, the penetrating shaft 2 penetrates through one side of the barrel body 3 from the outer side; the lifting ring 4 and the blade 1 penetrate through the penetrating shaft from the barrel body 3; two ends of the penetrating shaft 2 are fixed at reserved holes of the barrel body 3; the blade 1 is retained between two retaining pins 5 by the retaining pins 5.

The working principle is as follows: the blade tips of the blades 1 are automatically opened towards two sides through the dead weight of the two movable blades 1, when the tool goes down in the water pipe, the blade tips slide along the pipe wall, the inner diameter of the pipe is reduced, the blade tips contract inwards due to resistance, and when the inner diameter of the pipe is increased, the blade tips are opened towards two sides due to the action of gravity; when the tool goes up in the water pipe, the blade tips slide along the pipe wall, when the inner diameter of the pipe is increased, the blade tips are opened towards two sides under the action of gravity, when the inner diameter of the pipe is decreased, the blade tips are propped against the pipe wall by the resistance of the pipe, and cannot be decreased, at the moment, the steel wire rope is lifted above a wellhead through a crane and is tied on the hanging ring 4, so that the tool which bites the water pipe can be lifted out of the well together with the water pump of the water pipe, and fishing is finished.

The use process comprises the following steps: the tool is manually placed into a wellhead by a steel wire rope connected with a lifting ring 4, the tool is smoothly placed into a fractured water pipe in the placing process by observing the tool through a camera, the steel wire rope is slowly lifted upwards after the tool is continuously placed over the length of a single water pipe, when the steel wire rope is not lifted, a blade 1 of the tool is clamped into a gap at the position of a water pipe joint, then a crane is replaced to lift the steel wire rope, the tool and the water pipe are lifted together, after a first water-saving pipe is lifted out of the wellhead, a conventional water pipe replacing method is replaced to continue a section of water pipe taking-out, a last water-saving pipe is connected with a water pump, and after the last water pipe and the water pump are taken out, the fishing work of the deep well pump can be completed.
