Description

{Device for Guiding the Cable of Deep Well Inspect}

The present invention relates to a device for guiding an incoming cable for internal investigation of an underground water, and more particularly, to an underground water depth control device capable of emergency stopping to prevent sudden descent of a wire cable that is disconnected or suddenly released by an external factor To an electric wire cable guide device.

Generally, the underground water channel is usually drilled to a certain depth below the surface layer, the inner casing, which is a pipe tube, is inserted into the drilled hole, and the groundwater of the rocky aquifer in the groundwater I have been using it by pumping it.

In the groundwater, the groundwater flowing in the fracture joint layer formed on the weathered rock or the soft rock layer flows into the groundwater through the holes formed in the inner casing of the groundwater, and the groundwater is pumped and used.

Since the quality of the groundwater supplied from the groundwater is usually clear and clean, the pollution of the water environment has become serious, and as interest in clean drinking water has increased, efforts to develop uncontaminated groundwater have been actively carried out.

Therefore, in order to find uncontaminated groundwater, it is essential to drill the groundwater well as a drill and to measure the water quality and water level of the groundwater.

In addition, during the drilling to develop groundwater, the soil layer and the weathered rock layer are pierced naturally, and the piercing section is formed by passing through the soft rock layer, the normal rock, and the light rock layer successively.

As a result, groundwater that is susceptible to contamination or contamination has become a major factor in groundwater contamination of rock aquifers and groundwater in naturally uncontaminated rock aquifers without any resistance or filtration.

In order to develop underground water, the state of the inner wall of the perforated hole drilled at a certain depth below the ground is checked, the installation state of the inner casing penetrated into the perforated hole is checked, and the depth of the aquifer and the depth of excavation , And observation equipment such as a logger with a camera capable of observing the inside of the heart.

In order to measure the water quality and water level of the groundwater after drilling the groundwater, the water quality sensor and the pressure sensor installed at the end of the cable were sent down to the underwater floor and the water quality and water level were measured .

However, in addition to observation equipment such as a logger, a water level sensor, and a pressure sensor, an electric cable for transmitting power and data is downwardly entered into the inner casing of the underground water chamber. The upper end of the inner casing exposed to the ground surface is sharp Because of the uneven cut surface, the cable is broken by contacting the communication cable of the level gauge falling down into the inner casing or the communication cable of the logger, and the cover is broken. On the other hand, The risk of a safety accident in which a hand portion is injured by an upper cut portion frequently occurs.

And, if the coating insulator surrounding the conductor of the wire cable is broken, the cable cable is corroded by the water or moisture introduced through the damaged coating part, thereby shortening the service life and replacement period, increasing the maintenance cost and providing the main cause of malfunction In addition, noise is generated in the image data transmitted from the camera to the storage device, such as the logger, or the image transmission is not performed smoothly, resulting in reliability problems.

The second cylindrical member 123 covers the open upper end of the second cylindrical member 123, And a second upper plate 124 passing through the opening 125 through which the wire cable C passes through in interference, together with the observation equipment on the upper surface corresponding to the upper plate 130.

The hollow tube 121 serves as a path for guiding the lowering of the observation equipment and the cable cable C passing through the central hole 113 and the opening 125 while connecting the first lid and the second lid to each other .

The lower end of the hollow tube 121 may be provided with a flange 122 to be coupled to the first upper plate 112 of the first lid by a plurality of fastening members.

 The support 130 is provided in the second lid with an inner hole communicating with the opening 125 formed in the second upper plate 124 which is the upper surface of the second lid 120.

The supporting body 130 is shown to be fixed to the second upper plate of the second lid 120 or assembled horizontally, and has a box structure having an inner hole communicating with the opening 125 But not limited to, a pair of walls facing each other.

The support member 130 is connected to the first and second stop members 141 and 142 of the emergency stop unit 140 by a wire cable C released from a wound reel (not shown) in which the wire cable C is wound in the form of a scroll, A guide roller 135 contacting the electric cable C so as to be guided in a downward direction while being turned in a direction perpendicular to the horizontal direction so as to pass through at intervals formed between the pair of guide rollers 135, Vertical bars 136 may be included.

At this time, the guide roller may be provided with a pair of anti-skid protruding rings so as to prevent skewing of the cable cables which are in contact with both side edges of the electric cable, And can be movably assembled in accordance with the width of the wire cable.

The emergency stop unit 140 includes a first and a second stopper members 142 and 144 which are rotatably assembled to first and second rotation support pins 143 and 144 which are provided at opposite ends of the support member 130, 141, 144).

The first and second stopping members 141 and 142 are connected to the observation equipment and are connected to the supporting member 130 (see FIG. 1) at a predetermined interval, which is relatively larger than the thickness of the cable cable C, In the inner space of the main body.

At this time, the first and second stop members 141 and 142 have different lengths on the upper and lower surfaces, the length of the upper surface is relatively shorter than the lower side, and the outer surfaces are provided on both left and right sides, And a trapezoidal-shaped cross-section formed at a position relatively lower than the center of rotation of the fins 143 and 144.

In addition, the corner portions where the upper and second end faces of the first and second stoppers 141 and 142, which face the cable cable C, meet at a rapid descent, and prevent the damage caused by the contact with the cable cable C swinging And it is preferably formed as a round portion.

The first and second stop members 141 and 142 are spaced apart from the inner wall of the support body by a predetermined distance so that the first and second stop members 141 and 142 are rotated by an external force due to contact with the cable cable C, The operation can be performed more smoothly without the frictional resistance with the inner wall of the inner hole.

Thus, when the wire cable C, which has been unwound from the take-up reel and is then turned by the guide roller at a distance between the first and second stop members, descends at a constant speed as shown in FIG. 4A , The distance between the first and second stop members is relatively larger than the thickness of the electric cable, so that the first and second stop members descend into the interior of the inner casing without interference with the outer surfaces of the first and second stoppers.

On the other hand, due to a disturbance in which the middle of the wire cable C released from the take-up reel is disconnected or the control of releasing the take-up reel becomes difficult, the wire cable C is rotated at a relatively high speed The outer surface of the wire cable, which swings while passing between the first and second stop members, comes into contact with the outer surfaces of the first and second stop members facing each other. Therefore, And the first and second stop members are rotationally moved in the engaging direction via the first and second rotation support pins by an external force caused by the contact between the two contact members.

In this case, as the upper entrance of the gap narrows between the first and second stopping members facing each other, the electric wire cable is caught in contact with the upper edge portion of the first and second stopping members to perform an emergency stop, It is possible to prevent a lost accident that the broken wire cable is lost due to falling into the groundwater.
