Abstract
The utility model relates to an automatic recording device for sloping surface radial flow, which is formed by combining a radial flow collecting slot, a float barrel and an automatic recording device. The float barrel is communicated with the water collecting slot. The overflow mouth of a water outlet is a thin wall triangular weir of which the angle can be in the range of 20 DEG to 50 DEG. Thus, the dynamic process of radial flow can be automatically recorded. The utility model has the advantages of simple structure, easy manufacture and no electricity use, and the utility model is suitable for observational record of outdoor radial flow.
Description
The utility model belongs to the improvement of runoff determinator.
In the field inspection of the hydrology and soil erosion, surface runoff adopts runoff pond or runoff bucket to calculate its total amount more, but can not calculate the generating process of runoff at present.China's 88200157.4 patents have been reported a kind of automatic tipping bucket type flow rate-measuring device, because the record of this device is to be power with the electricity, and it is less to measure flow, thereby application in the open air is subjected to bigger restriction.The purpose of this utility model is exactly a kind of simple in structure, not electricity consumption of design, can directly write down the slope runoff self-recording unit of the dynamic process that runoff takes place.
The utility model mainly is made of three parts: runoff water leg, float tube and recording apparatus, wherein float tube and recording apparatus are prior art, just adopt this structure in existing rain gage.Of the present utility model being characterised in that combines this three part, and the float tube is communicated with water leg, and the overflow vent in the water side of water leg is the thin-walled triangular-notch weir, the filter screen lattice retaining that setting is arranged in water leg, under the water side, step is arranged in the water leg bottom, bottom land between step and triangular-notch weir has mudhole and port lid, and the angular range of triangular-notch weir can be 20 °-50 °, with about 30 ° for well.The principle of thin-walled triangular-notch weir is, enter water leg when triangular-notch weir overflows at runoff, when increasing its water surface that overflows, also increases flow, flow reduces its water surface and also reduces, and it is consistent with the water surface in the water leg, so after the angle of determining triangular-notch weir, the height of the water surface just becomes the function of runoff intensity in the water leg, thereby utilize the float in the float tube, the lifting that becomes recording pen with the lifting situation of the water surface, in chronological order the lifting change records of the water surface is got off with recording clock, just can learn the dynamic process of runoff intensity, reach the self registering purpose of runoff generation dynamic process.Can find out that by the structure of triangular-notch weir angle is more little, its measuring accuracy is high more, passes through but must can bear bigger run-off, so the triangular-notch weir angle is definite, should be as much as possible littler under the prerequisite that the maximum diameter flow passes through smoothly with guaranteeing mensuration, the thin-walled of triangular-notch weir also is as a same reason.Filter screen lattice retaining is to stop the branches and leaves of bringing water leg with runoff into, avoid stopping up and the accuracy of influence measurement at the triangular-notch weir place, and can diameter flow to the ripples that produce into water leg and play buffer action, if filter screen lattice retaining can have sparse different several when water leg is big.In water leg bottom towards the water side downward step, be for make the silt brought into runoff can buffer deposit with bigger space.
Accompanying drawing 1(also is a Figure of abstract) be the designed runoff of the utility model structural representation of record 1 device automatically.1 is that water leg, 2 is recording clock for guide rod, 10 for float connecting rod, 9 for recording pen, 8 for float tube, 7 for step, 6 for mudhole and port lid, 5 for thin-walled triangular-notch weir, 4 for filter screen lattice retaining, 3 among the figure.As can be seen from Figure, the utlity model has simple in structurely, manufacture easily, non-electric advantage, the measurement that is suitable for open-air runoff is observed.
Float tube in the utility model and recording clock can be buied in market for existing approved product, and water leg can be selected iron sheet or Plastic Welding or bonding forming for use; The float tube is connected the sidewall of water leg as shown in the figure, and its bottom is communicated; Recording clock is contained on the sidewall or float tube of water leg, and makes recording pen on the float tube can reach picture on the recording clock; Filter screen lattice retaining can select for use entanglement to make.
Claims (3)
1, a kind of slope runoff self-recording unit, it is characterized in that: mainly being combined by runoff water leg, float tube and recording apparatus constitutes, and the float tube is communicated with water leg, overflow vent in the water side of water leg is the thin-walled triangular-notch weir, and the angle of triangular-notch weir can be within 20 ° of-50 ° of scopes.
2, runoff self-recording unit according to claim 1 is characterized in that: the filter screen lattice retaining of setting is arranged in water leg, under the water side step is arranged in the water leg bottom, mudhole and port lid are arranged at the bottom of the water leg between step and the triangular-notch weir.
