Description
Technical field
The invention belongs to hydraulic engineering and ocean engineering survey facility field, particularly a kind of blocked open channel lowest water level is from note chi and method thereof.
Background technology
At present the traditional water gauge of the general use of level measuring of opening wide waters is carried out manually following the tracks of and reading or adopt electric water level gauge to carry out overall process record. The former need to arrange more patrolman, carries out continuously reading of water gauge water level, and working strength is large, error is also larger; The latter need to utilize Special Equipment to carry out data acquisition and transmission, general at special hydrometric station, water level survey station arranges, have high input, operating cost is also higher. The lowest water level of the lowest water level of river and lake, the lowest water level at seabeach, irrigation canals and ditches is to carry out the important parameter that lake, river health evaluating, seabeach development project and channel water consumption are calculated, adopt traditional measuring method cost higher, also inconvenient, therefore, certainly remember chi in the urgent need to a kind of open channel lowest water level easy, accurate and that working strength is little.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of blocked open channel lowest water level from note chi and method thereof.
The object of the invention is to be achieved through the following technical solutions:
Blocked open channel lowest water level comprises body frame, rule, lasso, alveolar surface, reading needle, roller bearing, vertical and messenger wire from note chi; Install reading needle and roller bearing on the top of body frame, one side of body frame is provided with alveolar surface, lasso is enclosed within the periphery of body frame, rule one end is connected with lasso, the rule other end strides across roller bearing through the front of body frame and is connected with vertical by messenger wire, vertical is at the back side of body frame in suspended state, and reading needle is in the front of body frame, and rule is in the inside of reading needle.
The sawtooth direction of described alveolar surface is downward. The front scale of described rule increases from top to bottom gradually, and rule is tape. The gravity of described lasso is greater than the gravity of vertical, and the density of lasso is less than the density of water.
Blocked open channel lowest water level from note method is: when the water level of open channel is reduced to below lasso, lasso declines thereupon, front rule is descending, vertical is up, until the water level of open channel is equal with lasso, in the time that the water level of open channel exceeds lasso, lasso will be blocked by alveolar surface, even if water level of open channel fluctuates, it is motionless that lasso still keeps, thereby realize the automatic record to open channel lowest water level.
The invention has the beneficial effects as follows: blocked open channel lowest water level is from the not power consumption of note chi, do not need artificial track record, do not rely on any miscellaneous equipment, can automatically open wide the lowest water level record in waters to river course, seabeach, lake, channel etc., the present invention is simple in structure, with low cost, easily manufactured, than traditional water level electrical measurement with artificial follow the tracks of that the means such as to read with the obvious advantage, have broad application prospects.

Detailed description of the invention
As shown in Fig. 1,2,3,5,6, blocked open channel lowest water level comprises body frame 1, rule 2, lasso 3, alveolar surface 4, reading needle 5, roller bearing 6, vertical 7 and messenger wire 8 from note chi; Install reading needle 5 and roller bearing 6 on the top of body frame 1, one side of body frame 1 is provided with alveolar surface 4, lasso 3 is enclosed within the periphery of body frame 1, rule 2 one end are connected with lasso 3, rule 2 other ends stride across roller bearing 6 through the front of body frame 1 and are connected with vertical 7 by messenger wire 8, vertical 7 is at the back side of body frame 1 in suspended state, and reading needle 5 is in the front of body frame 1, and rule 2 is in the inside of reading needle 5.
The sawtooth direction of described alveolar surface 4 is downward. The front scale of described rule 2 increases from top to bottom gradually, and rule 2 is tape. The gravity of described lasso 3 is greater than the gravity of vertical 7, and the density of lasso 3 is less than the density of water.
As shown in Figure 4, the rule 2 of blocked open channel lowest water level in note chi also can adopt the long chi of rigidity, and at this moment roller bearing 6 and vertical 7 can omit.
The present invention directly installs the blocked open channel lowest water level assembling from note chi in the position that need to measure water level, ensure that body frame 1 is vertical, and there is enough length to adapt to the variation of water level, calibration goes out water level elevation and blocked open channel lowest water level is remembered the chi reading needle conversion relation at 5 zero points of reading certainly, while bringing into use, lasso 3 is placed to current water level, read the indicated numerical value of reading needle 5 in the final time section of measurement period, be converted into actual water level elevation with conversion relation, obtain the lowest water level value in measurement period, lasso 3 is retracted to current water level position in the time that next measurement period starts, can start the lowest water level of next measurement period from note. blocked open channel lowest water level is from note chi installation, easy to use, and less investment, is worthy of popularization.
Blocked open channel lowest water level from note method is: when the water level of open channel is reduced to lasso below 3, lasso 3 declines thereupon, front rule 2 is descending, vertical 7 is up, until the water level of open channel is equal with lasso 3, in the time that the water level of open channel exceeds lasso 3, lasso 3 will be blocked by alveolar surface 4, even if water level of open channel fluctuates, it is motionless that lasso 3 still keeps, thereby realize the automatic record to open channel lowest water level.
