[0002] With the construction of ecological civilization, the improvement of ecological restoration function has received further attention. Soil and water conservation loss is directly related to the country's ecological security, flood control safety, etc., and has a significant impact on the natural environment, human life and social economy, and has received particular attention. Forests can play a role in both treating the symptoms and the root causes in the control of soil and water erosion. Monitoring surface runoff in wild forests can fully clarify their effect in slowing down soil and water conservation loss.

[0003] Therefore, the field soil surface runoff monitoring device is of great significance for the study of surface runoff. In the existing technology, surface runoff monitoring is carried out through simulation; the second is to monitor by building a runoff area surrounded by cement on all four sides. The required site is relatively large, which makes the construction of the runoff field difficult and expensive in the field, and it is easy to cause problems such as no water and unsatisfactory data. At the same time, the traditional runoff field only focuses on the results of runoff and sediment, lacks research on the flow generation process, resulting in unclear related situations such as flow peaks, and no effect in the process of soil and water management.

[0004] Therefore, it is necessary to provide a field portable soil surface runoff monitoring device to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] like Figure 1 As shown, the embodiment of the utility model provides a portable device for monitoring surface runoff, including a runoff box 1, a rain gauge 3, a surface runoff collection box 5, a power supply solar panel 6, a data acquisition and transmission module 7 and a pole 8. The data acquisition and transmission module 7 includes a low-power acquisition host, a 4G communication module, a 12AH lithium battery and a solar controller.

[0024] The runoff box 1 is used to receive the formed surface runoff to flow in smoothly. The runoff box 1 is connected to the rain gauge 3 through the first plastic transfer tube 2. The rain gauge 3 is connected to the surface runoff collection box 5 through the second plastic transfer tube 4. The vertical pole 8 is fixed on one side of the surface runoff collection box 5. The solar panel 6 for power supply is fixed on the top of the vertical pole 8 through the bracket 901. The data acquisition and transmission module 7 is fixed on the vertical pole 8 through the ring buckle 902. The rain gauge 3 is connected to the vertical pole 8 through the steel member 903.

[0025] When rainfall occurs, the surface runoff in the runoff box 1 enters the rain gauge 3 through the first plastic adapter tube 2. The rain gauge 3 quantifies the surface runoff of the rainfall event, and the quantified data is transmitted to the computer or mobile phone network terminal through the data acquisition and transmission module 7 for the next step of viewing and analysis, so as to achieve the purpose of remote real-time monitoring. The solar panel 6 is used for power supply, so that the flow monitoring can be quantitatively realized in the field, the dynamic process of surface runoff can be clarified, and the wireless signal transceiver can be used to transmit the signal to the network platform to achieve the purpose of remote monitoring, which is convenient for use.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the runoff box 1 includes a square box 101, a slope surface 102 is provided at the bottom of one side of the square box 101, and the slope of the slope surface 102 is 70°; a triangular water channel 103 is provided outside one side of the square box 101, and the triangular water channel 103 is arranged to be inclined downward at 20°; a water outlet pipe 104 is provided at the bottom of the side of the triangular water channel 103 away from the square box 101, and the water outlet pipe 104 is connected to the rain gauge 3 through the first plastic adapter pipe 2. The materials of the square box 101, the slope surface 102, the triangular water channel 103 and the water outlet pipe 104 are all made of stainless steel plates.

[0027] Among them, the bottom of the square box 101 is preferably a square structure of 40×40 cm. The edge of the square box 101, except for one side connected to the water channel 103, has a 2 cm extension. First, it is easy to operate, and second, the humanized design is not easy to scratch the hand. The square box 101 is embedded in the soil to form a barrier with the external environment, replacing the traditional cement blockage. The slope surface 102 is a 5.5 cm long slope inclined 70° toward the inside of the runoff box 1, which is embedded in the soil. The water channel 103 is a triangle inclined 20° downward. Both are designed to ensure that the surface runoff formed in the square box 101 flows smoothly into the rain gauge 3. The outlet pipe 104 and the water channel 103 are located on the same horizontal plane. Through the design of the runoff box 1, the runoff field with cement blockage in the traditional sense is replaced. Compared with the traditional runoff field, the runoff box 1 has the advantages of small size, low cost, reusability, applicability to multiple scenarios, and easy to meet monitoring requirements.

[0028] The outlet pipe 104 of the runoff box 1 is connected to the rain gauge 3 through the first plastic adapter tube 2. Before the connection, a matching cover is designed for the rain gauge currently circulating on the market, and a caliber matching the connecting pipe is reserved on the cover. The second plastic adapter tube 4 made of PVC is connected to the surface runoff collection box 5 at the outlet below the rain gauge 3, and at the same time, a steel member 903 made of stainless steel is used above and below it to fix it to the vertical pole 8. In addition, the solar panel 6 is fixed to the vertical pole 8 using a ring buckle 902 and a reinforcing screw, and the data acquisition and transmission module 7 contained therein is fixed to the vertical pole using a ring buckle 902. The overall combination can not only collect surface runoff, but also realize the quantification of surface runoff in the field and remote real-time monitoring of flow, and clarify the dynamic process of surface runoff after a rainfall event.

[0029] The working principle of a portable device for monitoring surface runoff is as follows: when in use, first, the runoff box 1 needs to be fixed in the soil, and the triangular water channel 103 and the outlet pipe 104 are dug in advance to ensure that the two are not higher than the square runoff box 1; at the same time, a part of the surface runoff collection box 5 is buried in the soil to play a fixing role; then the remaining part is connected and fixed, and the length of the first plastic transfer pipe 2 is determined according to the actual situation of the site. After the connection is completed, the device is in the usable stage. When rainfall occurs, the surface runoff in the square runoff box 1 enters the single-tipping bucket rain gauge 3 through the water channel 103 and the outlet pipe 104. The rain gauge 3 quantifies the surface runoff of the rainfall event, and the quantified data is transmitted to the computer or mobile phone network terminal through the data acquisition and transmission module 7 for the next step of viewing and analysis, so as to achieve the purpose of remote real-time monitoring. At the same time, the collected surface runoff flows into the surface runoff collection box 5 through the second plastic transfer pipe 4 to measure nutrients, etc., and finally complete the monitoring of the surface runoff of the forest soil.

[0030] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
