Abstract

The utility model discloses a portable well depth measuring instrument, which comprises a lower housing (1), an upper housing (2), a sliding hammer (3) slidable in the lower housing (1), a permanent magnet (5) inlaid on the top (4) of the sliding hammer, and a bleed hole (6) arranged on the upper part of the upper housing (2), wherein the lower housing (1) and the upper housing (2) are in thread connection, and a tongue tube (8) is arranged on the lower part of the lower housing (1). A contact of the tongue tube (8), serving as a starting switch, is connected in a circuit which comprises a double-core sheathed cable (9), a switch (14), a battery (15), a luminous tube (15) and a buzzer (16). When the sliding hammer (3) touches the bottom of a well and slides upwards, the tongue tube (8), under control of the magnetic field of the permanent magnet (5), actuates the circuit, and then an acoustic-optic alarm is given off and water level value on the cable (8) can be read.

Description

Portable well depth survey instrument

Affiliated technical field

The utility model relates to a kind of well depth survey instrument, especially is applicable to the portable well depth survey instrument of water resources management department and drilling crew measurement well depth.

Well depth often will be measured by water resources management department and drilling crew, adopts rope method under the weight usually, promptly fastens weight with a rope, toward transferring, when the people feels that weight contacts the shaft bottom, writes down the position of rope from well head, and this moment, the length of rope was exactly the degree of depth of well.This method is inconvenience but also unreliable not only, especially measures difficulty more with this method when well is deep.

The technical problems to be solved in the utility model provides a kind of portable well depth survey instrument of reliable operation simple in structure.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: have one in the bottom of the lower house of well depth survey instrument probe and slide mouthful, be provided with sliding hammer in the lower house, this sliding hammer can be along described slip mouthful slip, when probe contacts the shaft bottom, sliding hammer upwards slides with respect to lower house, for guaranteeing that sliding hammer slides rapidly reliably, top at lower house has steam vent, discharge and hinder the air that sliding hammer upwards slides, the top of described sliding hammer is provided with permanent magnet, bottom at upper shell is provided with tongue tube, when sliding hammer upwards slides near described tongue tube, the magnetic field of described permanent magnet makes the contact action launching indicating circuit of tongue tube, buzzer in the circuit and luminous tube send acousto-optic hint simultaneously, read the number of division on the cable this moment, can obtain the well depth surveyed, described upper shell and lower house are by being threaded, described circuit comprises the twin-core sheathed conductor, switch and battery, on the described twin-core RVV meter ruler scale is arranged, the minimum resolution of this scale is a millimeter, and the sectional area of wire of this RVV is not less than 0.75 square millimeter.

As further improvement of the utility model, described lower house, upper shell and sliding hammer adopt the stainless steel manufacturing, when it is characterized in that preventing to get rusty, also make probe have suitable weight, guarantee to keep when cable is gone into well vertical, the transition of described upper shell shoulder chamfering is not stuck when guaranteeing to propose probe from well.

As another improvement of the present utility model; at inner waterproofing materials filling fixedly tongue tube and the twin-core sheathed conductor used of described upper shell; have the heat-shrink tube seal groove on the top of upper shell, further fix with heat-shrink tube and protection twin-core RVV in the outside of sealing groove.

The beneficial effects of the utility model are, well depth survey instrument probe simple in structure is easy to clean and safeguard, probe moves up and down in well flexibly during use, is difficult for being stuck the reliability height.

Below in conjunction with drawings and embodiments the utility model is further specified.

Accompanying drawing is a structural representation of the present utility model.

1. lower houses among the figure, 2. upper shell, 3. sliding hammer, 4. sliding hammer top, 5. permanent magnet, 6. steam vent, 7. connecting thread, 8. tongue tube, 9. twin-core sheathed conductor, 10. upper shell shoulder chamfering, 11. heat-shrink tube seal grooves, 12. heat-shrink tubes, 13. circuit assembly, 14. switch, 15. luminous tubes, 16. buzzers.

From the utility model embodiment shown in the drawings as can be known; sliding hammer passes the slip mouth of lower house bottom; the sliding hammer upper part diameter is greater than mouthful diameter that slides; it is little that a volume is inlayed at the top of sliding hammer; powerful magnet 5; the bottom of upper shell is provided with a tongue tube 8; the two ends of tongue tube link to each other with two leads of twin-core RVV respectively; with the waterproof and sealing material filling tongue tube and twin-core RVV are fixed in the upper shell then; the reusable heat draw puts the top of twin-core RVV and upper shell; further fix and protection twin-core RVV, circuit assembly 13 is contained in the cable hank.

Rotating cable hank during use puts down probe along well head, sliding hammer upwards slided with respect to lower house after probe contacted the shaft bottom, when the magnet on sliding hammer top during near tongue tube, the closing of contact start-up circuit of tongue tube, send acousto-optic hint, read the number of division on the cable this moment, can obtain the water level of being surveyed.
