Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
As shown in Fig. 1 to 2, a kind of rainwater invasion and attack earth's surface demonstrator that the application provides, is applicable to education sector, can vividly reflect intuitively the erosion condition of rainwater to different earth's surfaces, effectively assist the understanding of student to course content, thereby improve the quality of teaching further.
Above-mentioned a kind of rainwater invasion and attack earth's surface demonstrator, comprise the water pump 1 being communicated with water source and the casing 2 that is mounted with at least one earth's surface, the sparge pipe 11 of water pump 1 is located at the top of casing 2, the base plate 21 of casing 2 is provided with at least one freeing port 22, and the below of freeing port 22 is provided with and equates with freeing port 22 quantity and header tank 3 one to one.
In order to strengthen the control to current size, be convenient to the observation of student to erosion process, a water flow control valve 12 is installed on sparge pipe 11 in the application.
For convenience of recovery to precipitation and prevent that precipitation from splashing down ground, in the application, the base plate 21 of casing 2 is close in the upper edge of header tank 3, is drawing and pulling type design.
Increase discharge for reducing pump bigcatkin willow journey, in the application, water pump 1 is submersible type water pump, and the water inlet of submersible type water pump is placed in water source.Because submersible type water pump can be installed in water, water inlet is directly communicated with water source and need to be by remote flexible pipe, has greatly reduced pump bigcatkin willow journey, thereby has effectively increased discharge.
In the application, water pump 1 comprises motor, switch and power supply, motor, switch and power supply are electrically connected and form loop successively, it should be noted that, switch is positioned over outside casing 2, the convenience that not only can improve operation can also reduce the risk of short circuit, specific to the application, power supply is exactly the accumulator that is built in water pump 1.
For ease of the laying of surface soil and reduce soil and the surface of contact of freeing port, in the application, freeing port 22 is crescent shape and digs on the edge of box bottom 21, due to the minimizing of surface soil and freeing port 22 surface of contact, prevent that too much soil from falling into freeing port 22 under Action of Gravity Field and effect that impact demonstration is normally carried out thereby played.
