Detailed Description
Examples
The handheld water depth measuring instrument of the embodiment is shown in fig. 1, and comprises a telescopic connecting rod 9, a handle 13 arranged at the top end 9 of the telescopic connecting rod, and a sensor housing 4 hinged at the bottom end of the telescopic connecting rod 9. As shown in fig. 3, the top of the sensor housing 4 has a fixed plate 8, the top of the fixed plate 8 has a hinge shaft hole, and the telescopic link 9 is hinged to the sensor housing 4 by a stainless steel hinge shaft 81 passing through the hinge shaft hole. The joint of the fixed plate 8, the sensor shell 4 and the telescopic connecting rod 9 is tightly sealed, and water flow is prevented from entering. Due to the design of the hinge shaft, the direction of the sensor shell 4 can be adjusted by a measurer at will, and measurement of river channels in different terrains is facilitated.
As shown in fig. 2 and 4, the bottom of the sensor shell 4 is provided with a through hole, and the bottom of the through hole is covered with a filter screen 1 so as to block branches, weeds, garbage and other impurities in water and prevent the instruments from being polluted; the top of the through hole is covered with a blocking piece 2, and the blocking piece 2 is connected with a water depth pressure sensor 3, so that the water depth pressure is transmitted to the water depth pressure sensor 3 through the blocking piece 2, and the water depth pressure sensor is prevented from being damaged by solids such as silt particles and the like in water; depth of water pressure sensor 3 is connected with PLC controller 5, has waterproof partition 7 in sensor housing 4, two upper and lower chambeies are cut apart into with sensor housing 4's inner space, and wherein the intracavity that through-hole and depth of water pressure sensor are located the below, and PLC controller 5 is located the intracavity of top, like this, further strengthens water proof effect, thereby avoids PLC controller 5 to be drenched by water and causes the damage.
The PLC controller 5 is connected with an LED display 11, the LED display 11 is installed on the top side wall of the telescopic connecting rod 9, and a battery 12 for supplying power to the PLC controller 5, the LED display 11 and the water depth pressure sensor 3 is installed in the handle 13. The battery 12 is a rechargeable lithium ion storage battery and is provided with a charging USB port, so that the battery has larger electric capacity and is more convenient to charge and suitable for field operation.
The telescopic link 9 is a hollow structure, and internally houses the necessary wires 6 between the LC controller 5, the LED display 11, and the battery 12, etc.
The handle 13 is also provided with an actuating switch 10. As shown in fig. 5, the start switch 10 is connected in series in the circuit.
The sensor housing is made of stainless steel; can be prevented from being damaged by hard foreign matters in water
The telescopic connecting rod 9 is made of carbon fiber materials, so that the telescopic connecting rod is lighter in weight, stronger in corrosion resistance and higher in strength, and meets the requirement of long-distance measurement.
