Abstract
The utility model relates to a buried-type trigger for indoor dam-break experiments, which belongs to the technical field of indoor dam-break experimental appliance. The trigger comprises a lockable casing, wherein a conductive fixing electrode and a conductive movable electrode are arranged inside the casing respectively; the fixed electrode is arranged in a ring shape along the inner wall of the casing and is connected with a first external terminal extending out of the casing; the movable electrode consists of an oscillating bar and a pendulum bob which are hung at the middle part of the internal casing and connected with each other; and one end of the oscillating bar is fixed at the upper part inside the casing and is connected with a second external terminal extending out of the casing, and the other end thereof is fixedly connected with the pendulum bob. Compared to the prior art, the novel structure newly adopted by the utility model can provide an indoor dam-break experiment with signals of the step-by-step breaking of a dam model, thereby strongly guaranteeing the smooth implementation of the indoor dam-break experiment.
Description
Technical field
The utility model relates to a kind of trigger that is used for indoor dam break test, belongs to indoor dam break test device technical field.
Background technology
At present, for the consideration to dam and dyke safety, people more and more pay attention to the burst research of mechanism of dam body.In the research of existing mechanism that dam body is burst, the dam break model test is very important research means, and wherein a kind of is to carry out indoor dam break model test.In this indoor dam break model test, the specific record instrument normally is set writes down the crevasse of dam body model and overflowing extending transversely, vertical incision under the current erosion effect of top and the dam body erosion process of tracing to the source, and obtain the procedure chart that the dam body model bursts gradually; The signal source of this specific record instrument then is to provide by sensor or the trigger that is arranged on the dam body model.
Understand according to the inventor, for sensor or the trigger in the existing indoor dam break test, rarely has report at present both at home and abroad, just in relative chamber, carried employing " electric contact " trigger in the report of dam break test method, but the concrete structure to this trigger is not documented, and how test effect does not see that report is arranged yet.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of indoor dam break test of flush type trigger that indoor dam break model test provides crevasse to burst process signal that can be.
The technical solution of the utility model is: the indoor dam break test of a kind of flush type trigger, comprise closed housing, be respectively equipped with conductive fixed electorde and float electrode in the described housing, first external terminal that stretches out housing arranged and is connected with in the form of a ring by described fixed electorde along inner walls; Described float electrode is positioned at continuous fork and the pendulum in housing middle part by suspension and constitutes; One end of described fork is fixed in the housing internal upper part and is connected with second external terminal that stretches out housing, and its other end and pendulum are affixed.
During use, earlier with trigger numbering of the present utility model and keep pendulum in the housing to be basic vertically stationary state layering imbedding one by one in the dam body model of indoor dam break test, the signal circuit that first and second external terminals are tested the specific record instrument by lead and external indoor dam break is connected again.When bursting appears in the dam body model in the test, trigger of the present utility model is promptly toppled over along with bursting of dam body model, the pendulum of float electrode produces swing in the trigger under action of gravity, the pendulum of swing promptly comes in contact with the ring-type fixed electorde, fixed electorde and float electrode and signal circuit are constituted connect the loop, thereby external specific record instrument is obtained and write down the dam body model signal of process that successively bursts, and then can draw the time isoline procedure chart that the dam body model bursts gradually.
The indoor dam break of flush type of the present utility model test trigger can be the signal that indoor dam break test provides the dam body model successively to burst process by the brand new that design did not have in the past, thus the finishing smoothly of the indoor dam break test of strong guarantee.
Description of drawings
Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the indoor dam break test of the utility model embodiment one flush type trigger.
Fig. 2 is the user mode synoptic diagram of the indoor dam break test of the flush type of Fig. 1 trigger.
Fig. 3 is the structural representation of the indoor dam break test of the utility model embodiment two flush types trigger.
Embodiment
Embodiment one
The indoor dam break test of the flush type of present embodiment trigger comprises the housing 1 of sealing as shown in Figure 1, is respectively equipped with fixed electorde 2 and float electrode in the housing.Fixed electorde 2 is beckets (as copper ring) of arranging in the form of a ring along inner walls, is connected with first external terminal 3 that stretches out housing on the fixed electorde 2.Float electrode is positioned at continuous fork 4 and the pendulum 5 in housing 1 middle part by suspension and constitutes; Fork 4 is metal wire (as copper cash), and the one end is fixed in housing 1 internal upper part and is connected with second external terminal 6 that stretches out housing, and its other end and pendulum 5 tops are affixed; Pendulum 5 is metal hammer body (as "painted-face" character in opera bodies).Housing 1 adopts the PVC material to make cube, and its physical dimension is all less than 2cm.
When the indoor dam break test of the flush type of present embodiment trigger uses, as shown in Figure 2, earlier with the trigger numbering of present embodiment and keep pendulum 5 in the housing 1 to be basic vertically stationary state layering imbedding one by one in the dam body model of indoor dam break test, the signal circuit that first and second external terminals are tested the specific record instrument by lead and external indoor dam break is connected again.When bursting appears in the dam body model in the test, the trigger of present embodiment is promptly toppled over along with bursting of dam body model, the pendulum 5 of float electrode produces swing in the housing 1 under action of gravity, the pendulum 5 of swing promptly comes in contact with ring-type fixed electorde 2, fixed electorde 2 and float electrode and signal circuit are constituted connect the loop, flicker continuously after light emitting diode 7 conductings, the indicator signal that external indoor dam break test specific record instrument is about to light emitting diode 7 is noted, along with the dam body model bursts gradually, the trigger of burying underground in the dam body model is successively toppled over and is sent signal, thereby external specific record instrument is obtained and write down the dam body model signal of process that successively bursts, and then can draw the time isoline procedure chart that the dam body model bursts gradually
Embodiment two
The indoor dam break of the flush type of present embodiment test trigger structure and embodiment one are basic identical, as shown in Figure 3 different, 1) fork 4 is silver strips; 2) pendulum 5 middle parts have through hole 8, and it is affixed with pendulum 5 bottoms that the other end of fork 4 passes through hole 8.Like this, because silver strip is softer and good elasticity is arranged, and the length that has prolonged fork 4; Therefore when toppling over, trigger has higher sensitivity, and more durable in use.
The various embodiments described above that are not limited to of the present utility model, such as: 1) fixed electorde 2 and float electrode also can adopt other conductive materials to make; 2) housing 1 also can adopt other resistant materials to make; 3) scheme of embodiment one, two can make up mutually; Or the like.All employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of the utility model requirement.
