Water level measuring device for river model test

Abstract

The invention relates to a water level measuring device for a river model test, which particularly structurally comprises a depth vernier caliper and a test pin (3), wherein the depth vernier caliper comprises a caliper base (1) and a caliper body (2); the caliper base (1) is provided with a longitudinal groove; the caliper body (2) slides up and down in the longitudinal groove of the caliper base (1); the test pin (3) comprises a pin head and a pin tail; the pin tail of the test pin (3) is fixed on the lower end of the caliper body (2); and the pin head of the test pin (3) downwards extends from the lower end of the caliper body (2). The water level measuring device disclosed by the invention has the advantages of higher measurement accuracy, lower production cost, simple structure and convenience for manufacture, thereby saving the cost of the river model test and enhancing the data reliability of the river model test.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a water level measuring device for a river engineering model test. Background technique [0002] The river engineering model test is an important means of river research. It takes the actual river channel as a prototype and reduces it to a certain scale to make a river channel model. Then, according to the actual river flow and sediment conditions, the water flow is reproduced on the channel model. Movement and sediment movement, and then realize the simulation of the actual river. Similar to the composition structure of an actual river channel, the specific structure of the river engineering model may include a bank sub-model similar to a river bank. In practical applications, the river bank sub-model is usually two model side walls. At present, due to the limitation of the actual natural environment and the actual technical level, it is impossible to measure variou...

Problems solved by technology

[0004] In the existing river engineering model tests, commercially available water level measuring needles are usually used to measure the water level; the existing water level measuring needles have two ranges of 40cm and 60cm, both adopt 10 graduations, and the accuracy is 0.1mm. The price is generally 900-1300 yuan; it is obvious that the existing water level probe not only has low measurement accuracy, but also has high cost, so the existing water level probe not only cannot guarantee the accuracy of water level measurement in the river engineering model test, but also increases Experimental cost of river engineering model test
