Abstract

The utility model discloses a deep hole fishing device. Including threaded steel ring, spring leaf, screw, the spring leaf passes through the inner edge of fix with screw at the steel ring. Its characterized in that: the fishing device comprises steel ring, spring leaf, screw, and 6 flat spring piece evenly distributed are at the inner edge of steel ring. The utility model discloses a set up the overhanging spring leaf of buckling at the steel ring inner edge, and install the device on the rig drilling rod, it is fixed to utilize the spring leaf to open the probe that the direction will lose, its better elasticity produces great gripping power to the probe, the problem of traditional salvage mode success rate lower is solved, furthermore, the applied technology is simple, low manufacture cost, the rate of recovery of probe has been improved, considerable economic benefits has been brought, and avoided losing the problem of probe to the radioactive contamination of environment, accord with the green, sustainable development's principle.

Description

A kind of deep hole fishing device

Technical field

This utility model relates to geotechnical investigation field, is specifically related to a kind of deep hole fishing device.

Technical background

In the exploration process of Geotechnical Engineering, for verifying lithology and the occurrence of rock stratum, generally carry out boring prospecting.Have to be to prospecting hole deviational survey during boring prospecting, deviational survey probe is a kind of cable and the long metal bar with radioactive substance of cable wire connection, its working method is: goed deep into by probe in hole, utilizes the cable traction connected, and utilizes the cable transmission data connected.Owing to the quality in prospecting hole limits; during deviational survey, often have stone drop; and then cause probe hole clipping; the method solved is repeatedly to lift probe; but can cause the most locked sometimes; the cable wire that connects of probe is pulled off under bigger coupling mechanism force effect, which results in probe and loses in hole.If salvaging probe not in time, owing to probe blocks inspecting hole, causing survey cannot be carried out, the duration can be produced and being delayed, adding that the price of probe is higher, it will cause bigger economic loss；Meanwhile, containing radioactive substance in probe, if not salvaging probe, radioactive pollution can be caused in the stratum of surrounding and subsoil water.In order to improve the utilization rate of probe, as far as possible reduction of erection time, save Financial cost, preserve the ecological environment, the fishing operation of a kind of probe of exigence.

Suitable patent is not also had currently for this situation.In Practical Project, the device adding iron ore in can using sleeve pipe under this situation is salvaged, and the method is simple to operate, but the probability that success is salvaged is smaller；In addition, some mechanical grippers can also solve the problem that probe is salvaged to a certain extent, but the method operation is complicated, and success rate is low, therefore is difficult to promote.

Summary of the invention

The purpose of this utility model is to provide the fishing device of a kind of deep hole probe, changes the problem that tradition Refloatation method is relatively low to probe success rate, additionally, this device technique is simple, cheap, it will to bring considerable economic benefit.

The scheme that the above-mentioned technical problem of this utility model solution is used is: a kind of deep hole fishing device, including threaded steel ring, spring leaf, screw, spring leaf is fixed by screws in the inner edge of steel ring.

As preferably, described steel ring is made up of common iron.

As preferably, described spring leaf is made up of spring steel.

The beneficial effects of the utility model are:

(1) a kind of deep hole fishing device of the present utility model, spring leaf utilizes it to open direction and can take advantage of a situation and fixed by the probe of loss, its preferable elasticity can ensure that, on the premise of not damaging probe, probe produced bigger grip, improves the success rate of salvaging.

(2) a kind of deep hole fishing device of the present utility model, simple structure, processing technique operation is few, and part concordance is good.

(3) a kind of deep hole fishing device of the present utility model, as a kind of spare and accessory parts of existing rig, it is not necessary to develop other driving carrier.

Accompanying drawing explanation

Below in conjunction with the accompanying drawings this utility model is described in further details:

Fig. 1 is the top view of a kind of deep hole fishing device of the present utility model；

Fig. 2 is the profile of a kind of deep hole fishing device of the present utility model；

Label in schematic diagram: 1, steel ring；2, spring leaf；3, screw.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in detail.

As shown in Figure 1 and Figure 2, a kind of deep hole fishing device, including steel ring 1, spring leaf 2, screw 3, spring leaf 2 is fixed on the inner edge of steel ring 1 by screw 3, it is characterised in that: described fishing device is made up of steel ring 1, spring leaf 2, screw 3, and described steel ring is made up of common iron, there are 12 screwed holes inner side, outer rim has screw thread to be distributed, and spring leaf 2 has 6, and the inner edge along steel ring 1 is uniformly distributed.

In the present embodiment, a kind of deep hole fishing device of design, in use, the spring leaf 2 being fixed on around steel ring 1 is taken advantage of a situation and is blocked by salvaged probe, and steel ring 1 has higher intensity, it is ensured that salvage smoothly completes.

In the present embodiment, by the setting of steel ring screw thread, whole device is made to be easy to handling.

In the present embodiment, by the setting of spring leaf, reduce the damage to salvaged probe, and improve the success rate of salvaging.

Above-described embodiment is only better embodiment of the present utility model, specifically understands technology of the present utility model design and essential implementation in conjunction with accompanying drawing, is not defined protection domain of the present utility model.

Claims

1. a deep hole fishing device, including steel ring (1), spring leaf (2), screw (3), it is characterized in that: spring leaf (2) is fixed on the inner edge of steel ring (1) by screw (3), spring leaf (2) has 6, and the inner edge along steel ring (1) is uniformly distributed.

A kind of deep hole fishing device the most according to claim 1 is characterized in that, described steel ring is made up of common iron, and there are 12 screwed holes inner side, and outer rim has screw thread to be distributed.
