Fig. 2 shows the shape of screw tap lid 4, and maximum gauge is screw thread, interior diameter and instrument storehouse protection tube 6 The interior diameter of interior diameter and screw tap lid 2 equates; All leave aperture in the middle of the two screw taps lid cable is passed through, screw tap Tops all is welded with a nut, and its internal diameter is greater than aperture, and cable is sticked with the agent cast by rear usefulness; The screw tap lid 2 is for the first time sealing, and its maximum gauge equates for the upper top mouthful overall diameter of instrument storehouse protection tube.

Fig. 3 shows the shape of iron pan ring 24, and its weldering knot is protected in the instrument storehouse on the inwall of tube 6, its overall diameter The little 0.1cm of interior diameter than protection tube 6. The edge leaves aperture makes cable be bonded and sealed again by rear.

Fig. 4 shows the structure of reducer pipe 9, the maximum gauge phase of its maximum gauge and the transparent organ pipe tube 32 of sighting distance Deng, and less than the 3cm of motor-pumped well pipe internal diameter, minimum diameter is greater than the 0.1cm of the overall diameter of instrument storehouse protection tube 6. Reducer pipe 9 is the same with other reducer pipe, all is to guarantee that this instrument lifts by crane smoothly, and other reducer pipe comprises The bottom reducer pipe of the transparent organ pipe tube 32 of sighting distance, the bottom reducer pipe of gearbox 18 and borehole wall brush bottom reducer pipe 23, the upper middle part of reducer pipe 9 is welded with three push rods 8, push rod 8 be subjected to nut 7 and 28 and fixed screw 33 control.

Fig. 5 shows silk ring 11 shapes, and its maximum gauge is silking, protects the upper of tube 32 with the transparent device of sighting distance The middle part silk is joined, and minimum diameter is less than the internal diameter 1.6cm of transparent device 13, and it is the supporting member of transparent device 13.

Fig. 6 shows whole shape and the structure that the borehole wall is cleaned system's bottom borehole wall brush with water, its bottom circular cone deformation The footpath manage 23 with borehole wall brush in the lower top mouthful of steel pipe 20 thread join and to be connected, finer wire 22 passes the borehole wall, and to brush outer steel pipe 21 equal Even is fixed on its inwall, with fixed screw 26 outer and inner tube tightly is integrated again, and (outer steel pipe 21 is suitable The socket direction is cut into two halves), the top mouth of interior steel pipe 20 is welded with iron pan, its iron pan bottom be welded with again nut with 19 on axle of silk is joined fixing; The whole borehole wall is brushed (Fig. 6) after submersible motor is through the gearbox speed change, rotary speed Be 120 rev/mins, namely dispose scale and foul on the well inner tubal wall, tube wall is not damaged.

Whole Photoelectrical detector for motor pumped well working condition is as follows:

1, connects 220V two-phase alternating current source, open respectively general supply transformation distribution box; The alternating current voltage stabilizing is joined Electronic box, output voltage are 220V, and power is 15 kilowatts; Direct current transformation distribution box, output voltage are 12V, Power is 100 watts.

2, starting 5 kilowatt motors drive the hoist engine lowering or hoisting gear through gearbox, (behind the motor-pumped well mobile workshop again Face is furnished with the high sister block support of 2.5m) Photoelectrical detector for motor pumped well is put into well.

3, turn on 12V dc lighting lamp 12 (because there not being light in the well), starting is with the TV of TV channel functions Then can directly receive the picture signal that camera probe is sent, open again the power switch of camera probe 5, make Camera probe 5 normal operations, at this moment camera probe 5 is by steering gear 14 and transparency window 31, again through signal cable Be delivered on the terrestrial television, demonstrate the image of the whole week borehole wall on the TV television screen, the sand grains of well casing It is high-visible to sharpen material size and color and luster).

If 4 motor-pumped wells are long service life, the well casing in clear water can produce a kind of green scale, Well casing in the addle can produce the black scale, just can't see like this true colours of well casing on screen, causes Can not find the position at bad pipe place. Connect in this case brake bar (φ 22mm steel pipe, two with the silk head and Screw), starting submersible motor 17 drives the rotation of borehole wall brush, the scale on the cleaning tube wall through gearbox 18 Reach foul, show the real appearance of well casing.

5, after the Photoelectrical detector for motor pumped well that the utility model proposes enters in the water, because internal-external temperature difference is bigger, One deck water smoke can be produced on transparent device 13 inwalls, roasting lamp (transparent device 13 in-built 12V direct current electric baking lamps) can be turned on Roasting 10 clocks are turned off roasting lamp after waiting water smoke to disappear again and are continued down to watch, until find bad pipe place.

6, the utility model can be verified silting material in the well in motor-pumped well silting situation, thereby determines to make Use which type of fishing tool, as the silting material of verifying is brick, stone etc., just needs to use grappling tool, as Fruit is that silt particle or short grained material just need to use the mud tube instrument of drinking. In the silting situation, use this motor-pumped well photoelectricity During survey meter, only need to clean the steering gear equipment of lower end and the borehole wall with water system and lay down, just can directly verify the shaft bottom The silting material.

A kind of Photoelectrical detector for motor pumped well that the utility model proposes, volume is little, in light weight, cost is low, benefit Greatly, adapt to town and country and scrap the motor-pumped well detection 95% or more, also be not subjected to the restriction at daytime and night, far away to motor-pumped well In the situation of power supply, join an output voltage 220V, power is that 20 kilowatts common alternating current generator just can Solve power issue, although the utility model science and technology one-tenths degree height is simple to operate, can be effectively, reliably and Verify rapidly motor-pumped well borehole wall situation and shaft bottom silting material, determine bad pipe position, take actual repairing measures (the benefit well device that another utility model that can adopt the inventor to declare simultaneously proposes) makes and scraps motor-pumped well through repairing Re-use after mending.

Embodiment:

The motor-pumped well photodetection instrument manufacturing process that employing the utility model proposes mainly is to get above-mentioned parts ready, fix and the fixing sealing of screw through casting, welding, lathe mantle fiber, sticking preparation, two ones have been produced, one one is adapted to the motor-pumped well pipe interior diameter is 190 to 210mm, and it is φ 290mm-φ 310mm that another one is adapted to the motor-pumped well pipe interior diameter.Through laboratory test, the utility model accuracy reaches 100%, on the spot the practice in: a deep-well 300m is arranged, shaft building 2 years, owing to when installing and using deep well pump, deep well pump directly has been sitting on the wall casing, and has not been had reliable fixing measure, pump seat is in unclasp under the free state and works, deep well pump one is to produce horizontal slip like this; The 2nd, produce, the bottom pump housing will be touched wall casing; The 3rd, produce high vibration during water pump operation, its vibration force is directly passed to reasons such as wall casing, causes the local borehole wall to be collided bad and gushes sand, and the motor-pumped well that causes investment to reach 6.5 ten thousand yuan is scrapped.With motor-pumped well photodetection instrument of the present utility model, the place, bad wall of well casing one place that only used just verify and determine in 15 minutes at motor-pumped well top 39.53m, surveyed through 48 minutes again, the middle part of well and bottom well casing are excellent, again through mending one hour repairing of well device, make motor-pumped well recover original function and reused at second day.
