Abstract
The utility model relates to a water surface and river bottom signal device which comprises a support. A lever and a cylinder are respectively arranged at the two ends of the support. A top cover is arranged at the top part of the cylinder. A magnetic steel block is arranged in the cylinder. The top part of the magnetic steel block is connected with one end of the lever through a connecting shaft. The other end of the lever is connected with a heavy punch through a rope. A spring is arranged in the cylinder on the connecting shaft. The two ends of the spring respectively lean against the magnetic steel block and the top cover. A normally closed reed switch is arranged at the bottom part of the magnetic steel block. A conducting wire is inserted into the normally closed reed switch. The two ends of the conducting wire are respectively connected with an underwater signal source and a fish lead. The utility model has the advantages that the structure is compact, the installation is convenient, the application scope is wide, the use is reliable, and the heavy punches or supporting plates with different areas and same weight can be selected according to different soil properties of the river bed of the cross section.
Description
Technical field
The utility model relates to a kind of water surface river bed telltale.
Background technology
Mountain area property river track cable flow-testing section is through a flood peak, variation in various degree will take place in the riverbed, it promptly is the station, lake region, Plain of stabilization of river bed, also to survey section elevation several times every year, " hydrometric cableway test standard " requirement that Ministry of Water Resources and Electric Power issues, survey the depth of water with cableway, " water surface signal begins to count up to when arriving when the river bed signal arrives and then stops to count ", be that the fish lead entry begins counting, fish lead touch the end stop the counting, the rope capacity of surveying is this vertical line depth of water, is exactly the bed elevation of this vertical line deeply with the water level elevation diminishing, existing measurement mechanism complex structure is installed loaded down with trivial details.
The utility model content
The purpose of this utility model provides a kind of water surface river bed telltale, and compact conformation is easy for installation, applied widely, uses reliably, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of water surface river bed telltale, comprise support, the two ends of described support are respectively equipped with lever and cylindrical shell, the top of cylindrical shell is provided with top cover, the inside of cylindrical shell is provided with magnet steel, the top of magnet steel is connected with an end of lever by coupling shaft, the other end of lever is connected with weight by rope, be positioned at the inner barrel place on the coupling shaft and be provided with spring, the two ends of spring are resisted against respectively on magnet steel and the top cover, the bottom of magnet steel is provided with normally closed tongue tube, interspersed lead in the normally closed tongue tube, and the two ends of lead are connected with fish lead with the underwater signal source respectively.
The beneficial effects of the utility model are: compact conformation, and easy for installation, applied widely, use reliably, can select the weight of the same weight of different area for use or claim supporting plate according to the different soil properties in section riverbed.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described water surface of the utility model embodiment river bed telltale; Fig. 2 is the described water surface of a utility model embodiment river bed telltale user mode reference view.
Among the figure: 1, support; 2, lever; 3, cylindrical shell; 4, top cover; 5, magnet steel; 6, coupling shaft; 7, rope; 8, weight; 9, spring; 10, normally closed tongue tube; 11, lead; 12, fish lead; 13, underwater signal source; 14, receiver; 15, relay; 16, depth sensor; 17, counter; 18, pole plate under water.
Embodiment
As shown in Figure 1, the described a kind of water surface of the utility model embodiment river bed telltale, comprise support 1, the two ends of described support 1 are respectively equipped with lever 2 and cylindrical shell 3, the top of cylindrical shell 3 is provided with top cover 4, the inside of cylindrical shell 3 is provided with magnet steel 5, the top of magnet steel 5 is connected with an end of lever 2 by coupling shaft 6, the other end of lever 2 is connected with weight 8 by rope 7, be positioned at cylindrical shell 3 inner places on the coupling shaft 6 and be provided with spring 9, the two ends of spring 9 are resisted against respectively on magnet steel 5 and the top cover 4, and the bottom of magnet steel 5 is provided with normally closed tongue tube 10, interspersed lead 11 in the normally closed tongue tube 10, the two ends of lead 11 are connected with fish lead 12 with underwater signal source 13 respectively.
During concrete the use, as shown in Figure 2, the utility model is fixed on fish lead 12 empennages, and fish lead 12 suspention backs make spring 9 compressions because of weight 8 effects, and magnet steel 5 leaves normally closed tongue tube 10, this moment, normally closed tongue tube 10 was in normally off, fish lead 12 not before the entry, underwater signal source 13 does not constitute the loop with on the bank receiver 14, and the relay 15 of receiver 14 is not worked, the output line of depth sensor 16 also disconnects, and counter 17 is not counted; After fish lead 12 entry, underwater signal source 13, rope, receiver 14, pole plate 18, water, fish lead 12, normally closed tongue tube 10 constitute complete output loop under water, receiver 14 work, the normally opened contact closure of relay 15, connect depth sensor 16 signals, counter 17 is started working, when fish lead 12 contact river bed, weight 8 weightlessness, spring 9 is upheld, and magnet steel 5 disconnects normally closed tongue tube 10, and the relay contact of receiver 14 discharges on the bank, counter 17 stops counting, thereby finishes the depth measurement process.
