Embodiment 1

[0023] Such as figure 1 , 3 As shown, the outdoor portable artificial rainfall simulation device of the present invention includes a vertical water delivery pipeline 1, a tee joint 2 and a horizontal water delivery pipeline 3, and the horizontal water delivery pipeline 3 connects with the vertical water delivery pipeline 1 through the tee joint 2 Connected, four branch pipes 31, 32, 33, 34 are connected to one side of the horizontal water delivery pipeline 3, and the two branch pipelines 31, 34 at both ends pass through an elbow 12 and the two ends of the horizontal water delivery pipeline 3 respectively. The two branch pipes 32 and 33 in the middle are connected to the middle part of the horizontal water pipeline 3 through a tee respectively; the length of the branch pipe 31 is the same as that of the branch pipe 33, and the length of the branch pipe 32 is the same as that of the branch pipe 34 , the length of the branch pipes 31,33 is longer than the length of the branch pi...

Embodiment 2

[0027] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is only that: the vertical water delivery pipeline 1 in this implementation is a split type, and is composed of at least two sections of pipelines, and the adjacent two sections of pipelines are connected by PVC joints 9 , to facilitate disassembly, and all the other are the same as embodiment 1.

Embodiment 3

[0029] Such as figure 2 As shown, the supporting device in this embodiment adopts five short vertical pipes 16, wherein, two short vertical pipes are arranged below the side of the flat water delivery pipeline, and the tops of the two short vertical pipes are bonded On the lower surface of the flat plate 8, the bottom ends of the two short vertical pipes are inserted into the tee sleeved on the horizontal water pipeline 3 and fixed; Knotted on the lower surface of the flat plate 8, its bottom end is inserted into the tee set on the branch pipe 31 and fixed; The lower surface, the bottom end of which is inserted into the tee set on the branch pipe 33 and fixed; the last short vertical pipe is set corresponding to the area where the motor is located, and the top of the short vertical pipe is bonded to the flat plate 8 in the area where the motor is located. The lower surface, the bottom end of which is pasted and fixed on the pipe wall of the third shower head. The upper ends...

Abstract

The invention discloses am outdoor portable artificial rainfall simulation device. The outdoor portable artificial rainfall simulation device comprises a vertical water conveying pipeline, a three-way connector and a horizontal water conveying pipeline, the horizontal water conveying pipeline is connected with the vertical water conveying pipeline through the three-way connector, four branch pipelines are arranged on one side of the horizontal water conveying pipeline in parallel, the length of the first branch pipeline is the same as that of the third branch pipeline, the second branch pipeline and the fourth branch pipeline are the same in length, and the first branch pipeline and the third branch pipeline are different from the second branch pipeline and the fourth branch pipeline in length; each branch pipeline is provided with a valve and a spray head, the first spray head and the third spray head are connected with the second spray head and the fourth spray head through connecting rods respectively, and the two connecting rods are arranged in parallel and connected with a motor through a reciprocating rocker arm pull rod; the motor is fixed to a flat plate, and the flat plate is fixed to a horizontal water conveying pipeline. The device is suitable for various field terrains, good in rainfall uniformity, light in weight and convenient to move, disassemble and assemble.

Description

technical field [0001] The invention relates to an artificial rainfall device, in particular to an outdoor portable artificial rainfall simulation device. Background technique [0002] Soil erosion destroys land, devours farmland, aggravates flood disasters, and has a serious impact on the high-quality development of ecological civilization construction. It is very important to implement soil and water loss monitoring, accurately grasp the soil and water loss under various terrain conditions and different rainfall intensities, and take targeted measures to effectively control it. [0003] In order to accurately monitor water and soil loss during rainfall, artificial rainfall devices are often used to simulate rainfall experiments. my country's existing artificial rainfall erosion-related tests can be roughly divided into two types: field in-situ tests and indoor simulation tests, of which field in-situ tests account for about 40%, and indoor simulation tests account for abo...
