DETAILED DESCRIPTION

[0028] The utility model is now described in further detail with reference to the accompanying drawings.

[0029] See also Figures 1 to 6 The utility model provides a technical solution: an automatic underground water level measuring device in a hole, comprising a moving seat 1, an L-shaped frame 3, a reel 5 and a probe 16, wherein the bottom four corners of the moving seat 1 are provided with self-locking universal wheels 2, an L-shaped frame 3 is fixed at the upper end of the moving seat 1, a through hole for bearing installation is opened in the middle of the L-shaped frame 3, a connecting ring 4 is rotatably connected to the inner part of the bearing, a reel 5 is connected to one side of the connecting ring 4 by a flange, a plurality of air-permeable grooves 6 are opened in an annular shape on the outer surface of the reel 5, an inner drying arc plate 7 is fixedly installed on both the upper and lower sides of the inner part of the reel 5, an outer drying arc plate 8 is fixed at the lower end of the L-shaped frame 3, reserved grooves for strip-shaped air nozzles 9 to be installed are opened at equal intervals on the outer sides of the outer drying arc plate 8 and the inner drying arc plate 7, a hot air pipe 10 is connected to one side of the outer drying arc plate 8 and the two inner drying arc plates 7, and a dryer 11 is fixed on the top of the L-shaped frame 3;

[0030] The outside of the reel 5 is sleeved with a plurality of spacer rings 12 at equal intervals, a connecting wire 13 is wound around the outside of the reel 5, one end of the connecting wire 13 is fixed to the reel 5 through a special-shaped frame 14 and a fixing bolt 15, and the other end of the connecting wire 13 is connected to a probe 16. A waterproof box 18 for installing a battery 17 is fixed inside the reel 5, and a buzzer 19 is provided on the upper side of the waterproof box 18;

[0031] The interior of each air vent 6 is fixed with a dustproof net 21 by means of an installation bolt 20. Considering that a connecting line 13 is generally installed on the existing water level measuring probe 16, moisture will adhere to the surface of the connecting line after the connecting line 13 enters the underground. The existing device is not provided with a drying structure, and is unable to dry the wet connecting line 13. The attached moisture will lead to the disadvantage of shortening the service life of the connecting line 13. The utility model can quickly dry the water stains on the surface of the connecting line by arranging an inner drying arc plate 7 and an outer drying arc plate 8 in cooperation with the dryer 11. In order to improve the drying effect, an extrusion plate 39 is provided on the path of winding the connecting line 13. The sponge blocks in the middle of the two extrusion plates 39 are used to pre-absorb the water stains attached to the outside of the connecting line 13. The extrusion plate 39 can also use a silicone scraper 42 to pre-scrape the water stains attached to the outer surface of the connecting line 13, thereby reducing the moisture content of the connecting line 13 by extrusion, thereby reducing the drying amount, and thus the drying efficiency is improved. When the device is tested, it is required before the test. Ensure that the air duct 23 and the hot air duct 10 are in the unplugged state. After the probe 16 enters the water, the liquid enters from the water-permeable hole of the probe 16 itself. When the two electrodes inside the probe 16 are soaked in water, a closed circuit is formed, and then the buzzer 19 is powered on to sound an alarm. Then, the length of the unwinding of the connecting wire 13 at this time can be measured to know the liquid level. In order to facilitate calculation, scale lines can be coated on the surface of the connecting wire 13. When drying, first fix multiple air ducts 23 with the pipe clamp 24 and the extended end of the hot compress tube, and then start the drying. The dryer 11 is switched on and the fan 26 conveys external air to the interior of the dryer 11 and contacts the electric heating rod 28. During this process, the motor heating rod heats the air, and the heated air is then conveyed to the interior of the inner drying arc plate 7 and the outer drying arc plate 8, and finally sent out by the strip air nozzle 9, thereby drying the connecting rope. The outer drying arc plate 8 dries the surface exposed to the outside of the reel 5, and the inner drying arc plate 7 can dry the upper surface of the connecting rope at the air vent 6, so as to improve the drying efficiency.

[0032] Among them, the side ends of the multiple hot air ducts 10 are provided with reserved holes for installing sealing plugs 22, and the upper end of each hot air duct 10 is provided with an extended end for the air guide duct 23 to be sleeved, and the air guide duct 23 is fixed to the extended end by a pipe clamp 24. The multiple air guide ducts 23 all penetrate into the inside of one side of the dryer 11, and the side ends of the hot air ducts 10 are sealed by setting the sealing plugs 22. This structure takes into account the situation that after the connecting rope is wrapped around the outside of the reel 5, there is a situation where liquid drips onto the inner drying arc plate 7 due to gravity and then enters the inner drying arc plate 7 from the strip air nozzle 9. At this time, the sealing plug 22 can be pulled out and the device can be tilted to discharge the accumulated water remaining in the inner drying arc plate 7.

[0033] The interior of the dryer 11 is divided by an insulation board 25, and a fan 26 is fixed on one side of the insulation board 25 through a bracket. The negative pressure end of the fan 26 passes through a pipe to the outside of the other side of the dryer 11, and the delivery end of the fan 26 passes through the other side of the insulation board 25. An electric heating rod 28 is installed on the other side of the insulation board 25 through an insulation block 27. The fan 26 is provided to transport the external air to the interior of the dryer 11, and the existence of the electric heating rod 28 can heat the transported air by heating it with electricity.

[0034] Among them, an extension sleeve 31 is integrally formed on one side of the waterproof box 18 to prevent water from entering the connection point between the first wire 29 and the second wire 30. The first wire 29 is connected to the buzzer 19 circuit, and the second wire 30 is connected to the inner core wire circuit inside the connecting wire 13. The inner core wire is arranged inside the connecting wire 13, and a waterproof layer 32 is provided between the connecting wire 13 and the inner core wire. The waterproof layer 32 is provided to provide waterproof protection for the inner core wire inside the connecting wire 13.

[0035] Among them, a grip ring 33 for the user to rotate the reel 5 is fixed on one side of the reel 5 through a support rod, and an anti-slip sleeve 34 is sleeved on the outside of the grip ring 33. The provision of the grip ring 33 facilitates the measurement personnel to rotate the reel 5 to complete the winding and unwinding of the connecting line 13.

[0036] Among them, special-shaped support blocks 35 are fixed on both sides of the front end of the movable seat 1, and guide wheels 36 are rotatably connected to the bottoms of the two special-shaped support blocks 35, and L-shaped blocks 37 are symmetrically arranged on the upper end of the movable seat 1, and limit bolts 38 are threadedly connected in the middle of the two L-shaped blocks 37, and one side of the two limit bolts 38 is fixedly installed with an extrusion plate 39, and an absorbent cotton block 40 is fixed to the middle of the outer side of the two extrusion plates 39 by screws, and connecting pieces 41 are fixedly installed on the upper and lower ends of the outer sides of the two extrusion plates 39, and a silicone wiper 42 is sleeved on the outside of each connecting piece 41, and the side wall of each silicone wiper 42 is in conflict with the side wall of the connecting line 13. By arranging the absorbent cotton block 40 and the silicone wiper 42 in the middle of the extrusion plate 39, the water stains on the surface and inside of the connecting line 13 are pre-treated, thereby reducing the water content of the connecting line 13, thereby reducing the moisture content of the drying.

[0037] Among them, a counterweight cone 43 is fixed to the outside of the probe 16 through a connecting rope, and the counterweight cone 43 is located below the probe 16. The counterweight cone 43 is provided to counterweight the probe 16, which facilitates the probe 16 to sink into the hole to be detected by gravity, so as to complete the detection of the groundwater level in the hole.
