The utility model is characterized in that the recording papers are attached to a plane carrier and are vertically arranged with the recording pen, and the recording papers are horizontally pulled to advance in equal distance by a pair of pressing rolls arranged on the bottom board of the dots printing recorder. Compared with the existing recorder or data collector, the utility model has simple structure, convenient operation and management and cheap price without using electric power.
Description
Technical field
The utility model relates to a kind of and the supporting flow measuring instrument of mountain region small watershed runoff collection system, be mainly used in the monitoring and the experiment of artificially-simulated rainfall runoff of small watershed undercurrent, crack stream, spring, belong to the small hydraulic project equipment technical field of agricultural water conservation retaining.
Background technology
At present in the small watershed hydrologic monitoring, mainly comprise the monitoring of rate of discharge, the monitoring of rainfall and the monitoring of slope runoff sub-district, wherein the monitoring of slope runoff sub-district is the weakness among the three, reason mainly is: first utilizes the weir method of water level-discharge relation ultimate principle monitoring small watershed rate of discharge, under the situation that guarantees measuring accuracy, its minimum measurement of discharge is all at 30m
3More than/the h, be difficult to the dynamic changing process of low discharge is more carried out continuous monitoring.The second, utilize the tipping bucket technology to carry out flow measurement, though existing application the in the monitoring of rainfall particularly, the record problem is to influence the key factor that the tipping bucket technology is able to widespread use always.At present, with " switching signal " though be that the logout instrument or the data acquisition unit of core can be finished the record problem preferably,, its price comparison costliness is difficult to widespread usage.The applicant once in 2003 at this type of problem application a kind of simple in structure, the runoff rate dot type analyzer that recorded cost is low, application number is 03269640.X, adopt the roll type register to get record ready, to be the linear velocity of reel and angular velocity change with the increase of drum diameter the problem of this recording mode, and registration accuracy is affected.
Summary of the invention
The purpose of this utility model is at the problems referred to above, has proposed the double roll dots printing analyzer that a kind of level is got record ready, to improve registration accuracy.
The technical solution of the utility model is achieved in that this runoff rate double roll dots printing analyzer, its basic structure is by the tipping bucket that catchments that is held in by bearing and upset pedestal on the bearing, the register of getting ready that is provided with recording pointer and recording chart constitutes, and the bump contact that is provided with on the rear end of the recording pointer of described analyzer and the tipping bucket trip shaft contacts; It is characterized in that recording chart depends on that flat carrier is vertical with recording pointer to be provided with, advance by getting equidistant stretching of a pair of pressure roller level that is provided with on the register base plate ready.
The bump contact that the rear end of the recording pointer of described runoff rate double roll dots printing analyzer is provided with on the cam disc that is provided with on roller and the tipping bucket trip shaft contacts.
On the penholder of the recording pointer of described runoff rate double roll dots printing analyzer back-moving spring is set.
A pressure roller below of described runoff rate double roll dots printing analyzer is provided with the clock rotating disk, and pressure roller shaft is arranged on the middle hand rest of clock as initiative compression roller.
Another pressure roller of described runoff rate double roll dots printing analyzer is arranged on the pressing roller holder as from dynamic pressure roller by holddown spring.
The paper roll of described runoff rate double roll dots printing analyzer around get that the register base plate is provided with ready from movable reel.
The flat carrier that the recording chart of described runoff rate double roll dots printing analyzer depends on is the middle casing that crack is arranged, and the relative record pen is got the position ready and got the hole ready.
The utility model provides a kind of water flow and self registering runoff rate analyzer that records arbitrary period in direct mode, compare with existing record instrument or data acquisition unit, simple in structure, operational management convenience, electrification not, be more suitable for the collection of field test data, particularly price comparison is cheap.

Embodiment
Shown in Figure 1, flow measuring instrument of the present utility model is mainly got ready with the recording chart two large divisions of turning round automatically by the tipping bucket activation record pen that catchments and is constituted, it is to be supported on the trip shaft 8 by two tipping buckets 10 that catchment that oppositely are provided with each other to constitute that the activation record pen that catchments is got the part primary structure ready, the flowing water in mountain stream brook or the flowing water of rainmaking flow out from water delivering orifice 1, enter in one of them tipping bucket 10 that catchments by the funnel 2 that catchments, when water reaches a certain amount of, the tipping bucket 10 that catchments just can overturn automatically, the bump contact 5 that is installed in two cam discs 4 on the tipping bucket trip shaft 8 that catchments just can be pushed the roller B-2 of a recording pointer B-7, recording pointer will be finished the once task of getting ready on recording chart B-13 immediately, after instantaneous extruding external force disappears, recording pointer will return to original state under the effect of back-moving spring B-6.Simultaneously, tested current inject in another tipping bucket that catchments, thereby guarantee the continuity of current monitoring.Regulate the height of bolt by adjusting collecting water from runoff, regulate the equilibrium point of the tipping bucket that catchments, reach the purpose of the toggle frequency of controlling the tipping bucket that catchments.
Of the present utility modelly get that recording chart B-13 machinery mainly comprises the clock rotating disk B-12 that is arranged on the base plate B-1 among the register B ready, the rotating disc that the clock clockwork spring drives drive a pair of pressure roller with recording chart at the uniform velocity horizontal stretch advance, recording chart depends on the plane box vertical with recording pointer, one end is wrapped in to be got ready on the reel B-3 that is provided with on the register base plate, and recording chart can be the relative motion that unit makes level the time just when pressure roller rotates; Recording pointer is along with the size of the tested flow that catchments, and frequency is got in conversion ready, and the track of getting ready that the flow of unit interval produces is reflected on the recording chart 11 with rectilinear form, realizes the continuous recording to water flow.
In actual applications, at first according to the velocity of rotation and the radius of initiative compression roller, the nominal time on recording chart, set the upset volume of the tipping bucket that catchments again, obtain range resolution or temporal resolution that recording pointer is got ready.
The utility model can be readjusted above parameter according to the actual change situation of monitored flow, thereby improves the measuring accuracy of system.
