specific Embodiment approach 1

[0023] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment, a channel test bench with adjustable structure size and liquid level height of an open channel in this embodiment includes a channel 1, the channel 1 is a long strip channel, it also includes a movable plate 2, an aluminum profile Pressure frame 3, locking structure 4, multiple screw rods 5, multiple fixing nuts 6, two aluminum profile brackets 7, multiple aluminum angle structures 8 and sinking components, multiple screw rods 5 pass along the width direction of channel 1 Passing through a side plate of the channel 1, each screw rod 5 is connected and positioned by two fixing nuts 6, the movable plate 2 is movably installed in the channel 1 along the width direction of the channel 1, and the side end surface of the movable plate 2 Connected with a plurality of screw rods 5, two aluminum profile brackets 7 are respectively installed on the lower part of the two side plates in the le...

specific Embodiment approach 2

[0029] Specific implementation mode two: combination Figure 1 to Figure 2 To describe this embodiment, the movable plate 2 of this embodiment is a strip plate, and the height of the movable plate 2 is flush with the upper end surface of the channel 1 . Such setting is convenient to meet the liquid level height requirement during the test and prevents water from splashing out. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0030] Specific implementation mode three: combination Figure 1 to Figure 2 The present embodiment will be described. The aluminum profile press frame 3 of the present embodiment is a groove-shaped press frame. Such setting is convenient for installation on the channel 1 without affecting the water flow experiment, and it is also convenient for observing the water flow. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The utility model discloses a channel experiment table with adjustable open channel structure size and liquid level height relates to a channel experiment table and is to solve a problem that an existing channel experiment table cannot realize experiment measurement under various structural conditions. The experiment table is characterized in that a plurality of screw rods penetrate through one side plate of a channel along the width direction of the channel, each screw rod is connected and positioned through two fixing nuts, a movable plate is movably installed in the channel in the width direction of the channel and connected with the screw rods, two aluminum profile supports are installed on lower portions of the two side plates in the length direction of the channel respectively, two ends of an aluminum profile pressing frame are installed on the two aluminum profile supports, and the aluminum profile pressing frame is detachably connected with the movable plate through a locking structure. The experiment table is advantaged in that a sinking assembly is installed at a water flow downstream end of the channel, an angle between a movable water guide plate at the outlet and a sinking part is adjusted by rotating a control rod through a hand wheel, the free liquid level height is controlled, moreover, the upstream free liquid level height is stabilized, and the experiment table is for the channel experiment.

Description

technical field [0001] The invention relates to a channel test bench, in particular to a channel test bench with adjustable structure size and liquid level height of an open channel. Background technique [0002] Channel flow refers to the flow of water in an open flow channel in contact with the atmosphere, which belongs to a two-phase flow with a well-defined interface. For different channel structure sizes, the influence of the wall surface on the flow is different, resulting in flow differences under different structure sizes. By studying the flow characteristics in channels with different structural sizes and analyzing the influence of channel structural sizes on flow, it is of great significance for the research of channel design, sedimentation control, heat transfer structure improvement, and material transport efficiency. [0003] The existing channel test bench generally has a large structural size, and the structural size of the channel is fixed after manufacture,...
