Description
Technical field
The utility model belongs to hydraulic engineering and marine engineering survey facility field, and particularly a kind of magnetic-type open channel lowest water level is from remembering chi.
Background technology
To opening wide the traditional water gauge of the general use of level measuring in waters, carry out manually following the tracks of and reading or adopt electric water level gauge to carry out overall process record at present.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, in the urgent need to a kind of open channel lowest water level easy, accurate and that working strength is little, certainly remember chi.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of magnetic-type open channel lowest water level from remembering chi.
The purpose of this utility model is achieved through the following technical solutions:
Magnetic-type open channel lowest water level is from remembering that chi comprises body frame, rule, lasso, float slide block, magnet, reading needle, roller bearing, vertical and messenger wire; On the top of body frame, install reading needle and roller bearing, the built-in magnet of lasso, lasso is enclosed within the periphery of body frame, rule one end is connected with magnet, and the rule other end strides across roller bearing through the front of body frame and is connected with vertical by messenger wire, vertical at the back side of body frame in suspended state, float slide block is placed in the front chute of body frame, lasso is below float slide block, and reading needle is in the front of body frame, and rule is in the inside of reading needle.
The front of described body frame adopts ferrous material, and the density of lasso is greater than the density of water, and the density of float slide block is less than the density of water.The front scale of described rule increases from top to bottom gradually, and rule is tape.The total force of described lasso and float slide block is greater than magnetic friction force between lasso and body frame and the gravity sum of vertical, and the magnetic friction force between lasso and body frame is greater than the gravity of lasso and the gravity of vertical.
The beneficial effects of the utility model are: magnetic-type open channel lowest water level is from remembering not power consumption of chi, do not need artificial track record, do not rely on any miscellaneous equipment, can automatically to river course, seabeach, lake, channel etc., open wide the lowest water level record in waters, the utility model 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.

Embodiment
As shown in Fig. 1,2,3,5,6, magnetic-type open channel lowest water level is from remembering that chi comprises body frame 1, rule 2, lasso 3, float slide block 4, magnet 5, reading needle 6, roller bearing 7, vertical 8 and messenger wire 9; On the top of body frame 1, install reading needle 6 and roller bearing 7, the built-in magnet 5 of lasso 3, lasso 3 is enclosed within the periphery of body frame 1, rule 2 one end are connected with magnet 5, and rule 2 other ends stride across roller bearing 7 through the front of body frames 1 and are connected with vertical 8 by messenger wire 9, vertical 8 at the back side of body frame 1 in suspended state, float slide block 4 is placed in the front chute of body frame 1, lasso 3 is below float slide block 4, and reading needle 6 is in the front of body frame 1, and rule 2 is in the inside of reading needle 6.
The front of described body frame 1 adopts ferrous material, and the density of lasso 3 is greater than the density of water, and the density of float slide block 4 is less than the density of water.The front scale of described rule 2 increases from top to bottom gradually, and rule 2 is tape.Described lasso 3 and the total force of float slide block 4 are greater than magnetic friction force between lasso 3 and body frame 1 and the gravity sum of vertical 8, and the magnetic friction force between lasso 3 and body frame 1 is greater than the gravity of lasso 3 and the gravity of vertical 8.
As shown in Figure 4, magnetic-type open channel lowest water level is from remembering that the rule 2 in chi also can adopt the long chi of rigidity, and at this moment roller bearing 7 and vertical 8 can omit.
The utility model is directly installed the magnetic-type open channel lowest water level assembling and is certainly remembered chi in the position that need to measure water level, guarantee 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 magnetic-type open channel lowest water level is remembered chi reading needle 6 conversion relation at the zero point of reading certainly, while bringing into use, lasso 3 is placed to current water level, final time section at measurement period reads the indicated numerical value of reading needle 6, with conversion relation, be converted into actual water level elevation, obtain the lowest water level value in measurement period, when next measurement period starts, lasso 3 and float slide block 4 are retracted to current water level position, can start the lowest water level of next measurement period from note.Magnetic-type open channel lowest water level is from remembering chi installation, easy to use, and less investment, is worthy of popularization.
