Description

An assembled rainfall-adjustable simulated rainfall increase and decrease device

Technical field

The invention belongs to the technical field of ecological environment engineering, and specifically relates to an assembled rainfall-adjustable simulated rain increasing and decreasing device.

Background technique

In recent years, changes in precipitation patterns under the background of climate change have attracted widespread attention from experts and scholars at home and abroad. Research on ecosystem stability evaluation and ecosystem evolution prediction analysis under changes in precipitation patterns have become hot spots. Many studies have set up simulation experiments in which precipitation increases or decreases, providing important monitoring data to further reveal ecosystem responses to changes in precipitation. Most rainfall change simulation tests involve devices that simulate the increase or decrease of rainfall. The devices mainly include rainfall interception devices and rainfall redistribution devices. The rainfall interception device mainly simulates the decrease in rainfall when the climate becomes dry, and can simulate different precipitation reduction ratios based on the proportion of precipitation interception slots. The rainfall redistribution device mainly simulates the increase in rainfall when the climate becomes humid. By directing the rainfall intercepted in the rainfall reduction area into the rainfall enhancement area, the proportion of increase in precipitation in the rainfall enhancement area is equal to the decrease in precipitation in the rainfall reduction area. This device can be used to simultaneously set up two comparative treatments of rainfall increase and rainfall reduction, and can control the amount of rainfall increase or decrease by increasing or decreasing the number of precipitation interception slots and redistribution slots. This simulated rainfall increase and decrease device is widely used in areas with low rainfall in droughts, especially in studying the response of desert vegetation to climate change, and has achieved good monitoring data and research conclusions.

However, existing devices have problems in the following aspects:

1) The upper part of the rain reduction area is shaded because of the intercepting water tank, while the rain enhancement area has no shade. This results in differences in microenvironments such as temperature and wind speed between the rainfall reduction area and the rainfall enhancement area, which affects the reliability of the monitoring data.

2) The existing device has a long water transmission distance, and there is a certain time difference from rainfall to rainwater redistribution. The lag of rainwater redistribution may lead to certain experimental errors. Moreover, desert areas have heavy sandstorms, and sand and dust often cause blockage of water pipes and blocked channels, resulting in water retention and loss, which affects the effect of increasing rainfall in rainfall enhancement areas.

3) The increase or decrease in rainfall is determined by the number of rain-cutting troughs, and the rain-cutting troughs are fixed on the main frame. Therefore, the increase or decrease in rainfall cannot be adjusted at will. Moreover, since the main frame is fixed on the ground, it cannot be moved or moved at will. Change the location of the device. Therefore, most devices are disposable and will be scrapped after use, resulting in a lot of waste.

Detailed ways

As shown in Figures 1 to 5, the present invention provides an assembled rainfall-adjustable simulated rain increasing and decreasing device, which includes a main frame 2 and a interception and distribution device. The main frame 2 is divided into a rain increasing area 22 and a rain reducing area 23. area, the throttling distribution device includes an upper frame 1, a water tank 7, an angle adjustment mechanism and an opening adjustment mechanism. The upper frame 1 is hinged to the main frame 2 through a hinge 18. The water tank 7 is installed on the upper frame 1 and has several , the water tank 7 includes two weather shields 8 arranged in a V-shape and hinged to each other. Preferably, the rain screen 8 is made of a highly transparent organic glass plate. The water tank 7 is divided into a retention section and a redistribution section. The retention section is located at the reduction section. Above the rain area 23, the redistribution section is located above the rain enhancement area 22. The bottom of the rain shield 8 of the redistribution section is provided with a drain groove 21. The angle adjustment mechanism is used to drive the upper frame 1 to rotate relative to the main frame 2, thereby changing the water tank. 7, the opening adjustment mechanism is used to drive the hinged rain shield 8 to rotate, thereby changing the angle between the two rain shields 8.

Preferably, the main frame 2 is made of a number of corrosion-resistant, light-weight hollow stainless steel tubes, and the joints of the hollow stainless steel tubes are fixedly connected through corner pieces 20, thereby forming a frame that can be disassembled and assembled to facilitate installation. Overall assembly, transportation, loading and unloading.

Preferably, the opening of the drain 21 gradually increases as the distance from the interception section increases. When rainwater flows in the water tank 7, the further away from the interception section, the smaller the water flow is, which may easily lead to uneven distribution of the water volume in the rain-increasing area. Therefore, the water tank 21 is set in a form with a gradually increasing opening to ensure rainwater distribution. balanced.

Specifically, in the present invention, the angle adjustment mechanism includes a cross beam 3, a flange 5, a handle 4 and a connecting rod 6. The cross beam 3 is fixedly mounted on the main frame 2, the flange 5 is rotatably mounted on the cross beam 3, and the handle 4 The middle part of the connecting rod 6 is fixedly connected to the flange 5. One end of the connecting rod 6 is hinged with the handle 4 and the other end is hinged with the upper frame 1. Fastening bolts 14 are installed on the flange 5.

When the user holds the end of the handle 4 away from the connecting rod 6 and rotates it, the flange 5 can be directly driven to rotate around the beam 3. At this time, the height of the connecting end of the handle 4 and the connecting rod 6 will change, because the connecting rod Both ends of 6 are rotatably connected to the handle 4 and the upper frame 1 respectively, so the upper frame 1 can be driven to rotate relative to the main frame 2 through the connecting rod 6, thereby changing the inclination angle of the water tank 7 on the upper frame 1. After the angle adjustment is completed , only need to tighten the fastening bolts 14 so that the flange 5 and the beam 3 are relatively fixed.

Specifically, as shown in Figure 7, in the present invention, the opening adjustment mechanism includes several adjustment components.

The angle between the weather shields 8; conversely, when the guide rod 9 slides downward in the base 12, the height of the middle rod 13 can be driven down, and then the two rain shields can be driven through the adjustment rod 11 and the swing plate 10 8 opens, making the angle between the two weather shields 8 become larger.

Preferably, the opening adjustment mechanism also includes a control rod 15. The control rod 15 is fixedly connected to all the guide rods 9. In this way, the user only needs to directly pull the control rod 15 to drive all the guide rods 9 to slide, thereby adjusting the opening. The opening angles of all slots 7 are adjusted synchronously.

At the same time, when the position of the entire device needs to be adjusted, the positioning bolt 19 can be screwed in, the fixing rod 16 can be pulled out from the bottom, and the device can be moved .

To sum up, the working process of this device is: first assemble the main frame 2 and move it to a predetermined position, then insert the fixing rod 16 into the ground, tighten the positioning bolt 19, and then pull the control rod 15 to open the slot 7 Adjust to a suitable opening angle, and then turn the handle 4 to drive the flange 5 to rotate, thereby lifting the upper frame 1. After changing the slot 7 to a suitable tilt angle, tighten the fastening bolts 14.

The above descriptions are only preferred embodiments of the present invention and do not limit the present invention in any way.
