[0023] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The device for simulating the combined action of artificial wind and rain is an experimental device used to simulate the action of wind and rain in nature in a laboratory environment. This device is usually used to study the effects of soil erosion, plant growth, and the durability of building materials. The artificial simulation of wind and rain system has important value in experimental research and teaching practice.

[0025] See also Figure 1-Figure 6 As shown, the present embodiment provides a device for simulating the combined effect of artificial wind and rain, including a rainfall device platform 1. However, in the prior art, before use, due to the influence of outdoor and building environments, the rainfall nozzle is easily blocked by dust, insects, etc., which affects the normal operation of the rainfall nozzle, resulting in the simulated rainwater not being convenient to fall evenly, reducing the accuracy of the experiment, and manual cleaning requires a lot of time, reducing work efficiency. Therefore, the details are as follows: four support columns 11 are fixedly connected to the bottom of the rainfall device platform 1, and a dust shielding plate 2 is slidably connected to the inner wall of the support column 11. A screw rod 21 is rotatably connected to the inner wall of the dust shielding plate 2, and the upper end of the screw rod 21 is fixedly connected to the output shaft of the first motor 22. A water pump is provided inside the rainfall device platform 1 to simulate rainfall. The nozzle at the lower end of the rainfall device platform 1 is protected by adjusting the height of the dust shielding plate 2. A slide groove 111 is provided on the side of the support column 11 close to the dust shielding plate 2. The outer wall of the dust shielding plate 2 slides and fits in the slide groove 111. The outer wall of the dust shielding plate 2 slides firmly on the inner wall of the slide groove 111, thereby improving the stability of the up and down movement of the dust shielding plate 2.

[0026] Among them, a water pump is a mechanical device used to transport liquids or increase the pressure of liquids. The water pump increases the energy of the liquid by transferring the mechanical energy of the prime mover or other forms of energy to the liquid. This process is mainly used to transport various liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. A water pump is a mechanical device used to transport liquids or increase the pressure of liquids. This is common knowledge among people in this technical field and will not be elaborated here.

[0027] A dust exhaust column 23 is fixedly connected to the top of the cavity of the dust shielding plate 2, a spring 24 is fixedly connected to the top of the cavity of the dust shielding plate 2, a baffle 25 is fixedly connected to the upper end of the spring 24, the baffle 25 is adapted to the cavity size of the dust shielding plate 2, the baffle 25 is evenly provided with circular holes, the dust exhaust column 23 is inserted and adapted to the circular holes of the baffle 25, and at the same time, when the rainfall device platform 1 is performing precipitation work, the water falling on the dust shielding plate 2 can be blocked to the outer wall of the dust shielding plate 2 to the greatest extent, a water supply tank 12 is fixedly connected to the top of the rainfall device platform 1, the lower end of the rainfall device platform 1 is adapted to the cavity size of the dust shielding plate 2, the lower end of the rainfall device platform 1 is evenly provided with circular holes that are inserted and adapted to the dust exhaust column 23, when the nozzle at the lower end of the rainfall device platform 1 is plugged with the dust exhaust column 23, the dust exhaust column 23 squeezes out the dust in the circular holes of the nozzle, thereby cleaning the nozzle.

[0028] The outer side of the rainfall device platform 1 is fixedly connected to a cover shell 3, the outer side of the cover shell 3 is fixedly connected to a second motor 31, the output shaft at the end of the second motor 31 is fixedly connected to a fan blade 32, and the side of the cover shell 3 away from the second motor 31 is rotatably connected to a wind guide plate 33. By adjusting the angle of the wind guide plate 33, the blowing direction can be freely adjusted to better achieve the effect of wind and rain linkage.

[0029] Among them, the first motor 22 and the second motor 31 are both motors commonly used in the prior art, and their working principle is: an electromagnetic device that realizes electric energy conversion or transmission based on the law of electromagnetic induction. This is common knowledge in this technical field and will not be elaborated again.

[0030] The improvement of this embodiment is that:

[0031] Through the cooperation of the dust shielding plate 2 and the screw rod 21, when the device is not in use, the dust shielding plate 2 is adjusted to the nozzle under the rainfall device platform 1 to achieve dust protection for the nozzle, avoid the invasion of dust and insects on the nozzle, and improve the accuracy of the experiment. At the same time, the dust exhaust column 23 cleans the nozzle every time the dust shielding plate 2 works, thereby improving the work efficiency. Four support columns 11 are fixedly connected under the rainfall device platform 1, and the inner wall of the support column 11 is slidably connected to the dust shielding plate 2, and the inner wall of the dust shielding plate 2 is rotatably connected to the screw rod 21, and the upper end of the screw rod 21 is fixedly connected to the output shaft of the first motor 22. A water pump is provided inside the rainfall device platform 1 to simulate rainfall, and the nozzle at the lower end of the rainfall device platform 1 is protected by adjusting the height of the dust shielding plate 2.

[0032] In order to better realize the combined effect of wind and rain connection, the outer side of the rainfall device platform 1 is fixedly connected with a cover shell 3, the outer side of the cover shell 3 is fixedly connected with a second motor 31, the output shaft at the end of the second motor 31 is fixedly connected with a fan blade 32, and the side of the cover shell 3 away from the second motor 31 is rotatably connected with an air guide plate 33. By adjusting the angle of the air guide plate 33, the blowing direction can be freely adjusted to better realize the effect of wind and rain linkage.

[0033] Taking into account that the above-mentioned protective effect is still insufficient, a dust exhaust column 23 is fixedly connected above the cavity of the dust shielding plate 2, a spring 24 is fixedly connected above the cavity of the dust shielding plate 2, a baffle 25 is fixedly connected to the upper end of the spring 24, and the baffle 25 is adapted to the cavity size of the dust shielding plate 2. The movement of the dust shielding plate 2 drives the dust exhaust column 23 to fit closely to the lower end of the rainfall device platform 1 for secondary protection.

[0034] Considering that the dust exhaust column 23 needs to pass through the baffle 25 to contact with the lower end of the rainfall device platform 1, the baffle 25 is evenly provided with circular holes, and the dust exhaust column 23 is inserted into and adapted to the circular holes of the baffle 25. The dust exhaust column 23 is inserted into the circular holes on the baffle 25 and contacts with the lower end of the rainfall device platform 1. At the same time, when the rainfall device platform 1 is performing precipitation work, the water falling on the dust shielding plate 2 can be blocked to the outer wall of the dust shielding plate 2 to the greatest extent, preventing a large amount of water from accumulating in the cavity of the dust shielding plate 2.

[0035] Taking into account that the movement stability of the dust shield plate 2 driven by the single-thread rod 21 is insufficient and is prone to displacement, a slide groove 111 is provided on the side of the support column 11 close to the dust shield plate 2. The outer wall of the dust shield plate 2 slides in the slide groove 111, and the outer wall of the dust shield plate 2 slides firmly on the inner wall of the slide groove 111, thereby improving the stability of the movement of the dust shield plate 2.

[0036] In order to better achieve the rainfall effect, a water supply box 12 is fixedly connected above the rainfall device platform 1. The lower end of the rainfall device platform 1 is adapted to the cavity size of the dust shielding plate 2. Circular holes are evenly arranged at the lower end of the rainfall device platform 1 to fit the dust exhaust column 23. A water supply valve is arranged above the water supply box 12 to ensure that water is always input into the rainfall device platform 1 to increase the sustainability of the experiment. When the nozzle at the lower end of the rainfall device platform 1 is connected to the dust exhaust column 23, the dust exhaust column 23 squeezes out the dust in the circular hole of the nozzle to clean the nozzle.

[0037] In summary, the working principle of this scheme is as follows:

[0038] When the device for simulating the combined effect of artificial wind and rain of the utility model is used, the first motor 22 is turned on, and the output shaft at the end of the first motor 22 drives the screw rod 21 to rotate, and the dust shielding plate 2 on the outer wall of the screw rod 21 moves downward along the slide groove 111 on the inner wall of the support column 11, and the dust exhaust column 23 leaves the circular hole at the nozzle at the lower end of the rainfall device platform 1, and the upper surface of the baffle 25 in the cavity of the dust shielding plate 2 leaves the end of the rainfall device platform 1, and the spring 24 fixedly connected to the baffle 25 drives the baffle 25 to reset, and when the dust shielding plate 2 reaches the bottom, the first motor 22 is turned off, the rainfall device platform 1 and the second motor 31 are turned on to work, and the water pump inside the rainfall device platform 1 starts to deliver water to simulate rainfall, and the water delivery tank 12 delivers water to the water pump inside the rainfall device platform 1, and the second motor 31 is ... second motor 31 is turned on to work, and the second motor 31 is turned on to work, and the second motor 31 is turned on to work, and the second motor 31 is turned on to work, and the second motor 31 is turned on to work, and the second motor 31 is turned on to work, and the second motor 31 is turned on to work, and the second motor 31 is turned on to The output shaft at the end of the machine 31 drives the fan blades 32 to rotate, and the fan blades 32 rotate to discharge wind, and the wind guide plate 33 is rotated to adjust the wind direction. After use, the rainfall device platform 1 and the screw rod 21 are closed to stop the device from working, and the first motor 22 is turned on. The first motor 22 drives the screw rod 21 to rotate in the opposite direction, driving the dust shielding plate 2 to move upward. When the baffle plate 25 contacts the end of the rainfall device platform 1, it will be squeezed and move downward. The baffle plate 25 is synchronously squeezed to the spring 24 below, driving the spring 24 to move downward. At this time, the dust exhaust column 23 passes through the baffle plate 25 and is inserted into the circular hole of the nozzle at the end of the rainfall device platform 1. The dust shielding plate 2 covers the nozzle at the end of the rainfall device platform 1 as a whole. The first motor 22 is closed, and the dust shielding plate 2 continuously protects the nozzle at the end of the rainfall device platform 1.
