The loam cake of processing through the conductive material that is threaded in the pipe of said first pipeline section of the person in charge, said loam cake is provided with groove from top to bottom, and said groove is used to introduce two signal line of warning device, and a said signal wire is connected in said loam cake;
The top is installed with the insulation limiting plate in the pipe of said second pipeline section of the person in charge; The external diameter of said insulation limiting plate is greater than the bore of said first pipeline section of the person in charge; Offer spacing hole in the middle of the said insulation limiting plate, the aperture of said spacing hole is less than the bore of said first pipeline section of the person in charge;
Be provided with float body in the pipe of said second pipeline section of the person in charge, the top of said float body is connected with fly rod, and said spacing hole is passed in said fly rod upper end, and said fly rod top connects another said signal wire;
Said person in charge bottom is threaded the bottom of permeable through hole is set.
The beneficial effect of the utility model is:
During the touching water prode and extend into groundwater level of this underground floodometer, utilize the buoyancy of water that float body is driven on the fly rod and move and touch loam cake, thereby two signal line are connected, open alerting signal, reach the purpose of measuring underground water table.When this touches water prode and is used for underground water level measurement, touch that the signal wire end can not contact underground water in the water prode, can keep dry, it is malfunctioning, durable in use therefore can not to be corroded.
Adopt the touching water prode and can measure the groundwater level under any condition of dip meter of the utility model with direct supply, warning device, measurement mechanism.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail:
As shown in Figure 1, present embodiment has disclosed a kind of water prode that touches of dip meter, is made up of the person in charge 1, loam cake 2, insulation limiting plate 3, fly rod 4, floating body 5 and bottom 6.
Be responsible for 1 and be cylindrical structure, as shown in Figure 2, external diameter is even up and down, and the bore of first pipeline section 12 is less than the bore of second pipeline section 13, and is the notch cuttype transition between the internal diameter of first pipeline section 12 and second pipeline section 13.First pipeline section 12 is provided with the internal thread 11 of part, is used to connect loam cake 2; Second pipeline section 13 ports are provided with internal thread, are used to connect bottom 6.Be responsible for the 1 long 100mm of being, external diameter is 35mm, and the bore of first pipeline section 12 is that the bore of 20mm, second pipeline section is 30mm.
As shown in Figure 3, the bottom of loam cake 2 is provided with external thread 22, is used for cooperating with the internal thread 11 of first pipeline section 12, thereby loam cake 2 is fixedly installed in the person in charge's 1 port.The length of loam cake 2 is 50mm, and external diameter is 20mm, and the length of external thread 22 parts is 30mm.Offer the groove 21 of 3mm * 15mm in the loam cake 2, groove 21 is used to introduce two signal line, and two signal line all are connected in outside warning device.Loam cake 2 bottoms can connect the wherein termination of a signal line, and the top can be provided with the suspension ring hole.
