Description

Technical Field

[0001] The present invention relates to the field of building ventilation, and in particular to a photovoltaic power generation ventilation system. Background Art

[0002] In the field of building ventilation, there is a demand for air interaction within the building. Some high-altitude building ventilation systems are installed outside the building facade to guide the wind direction and achieve ventilation inside and outside the building. The matching accessories such as photovoltaic panels and sunshades have the need for cleaning and cooling. For this demand, the commonly used cleaning method includes high-altitude operations by cleaners, and common cooling or cleaning methods include spraying, etc. However, the labor cost of high-altitude operations by cleaners is high, it is not sustainable and long-term, and there are certain risks; and the existing nozzle spraying cannot be automated.

[0003] However, in actual production practice, the following problems exist:

[0004] 1. In the prior art, when cleaning or cooling nozzles, multiple nozzles need to be installed due to the size ratio of the nozzles to the building. However, due to water pressure issues and the problem of large-scale concentrated water use by multiple nozzles, the water pressure of the upstream nozzles is high and the water pressure of the downstream nozzles is low, which makes it difficult to evenly distribute the water pressure.

[0005] At the same time, facing this problem, it is not suitable to adopt an arithmetic method to solve it. The arithmetic method is that the size of each nozzle is much smaller than the size of the main pipeline, so that the upstream nozzle does not take away much pressure, thereby achieving equal pressure. This is only feasible in theory, and in fact the defects are too large. Since the size of the building pipeline cannot be too large, if the arithmetic method is used to solve the size of the nozzle, it will inevitably be smaller, resulting in a nozzle size that is too small and cannot realize more functions. Too small a size will also reduce work efficiency.

[0006] 2. Existing sprinkler nozzles are common, but they are not designed for use in high-altitude buildings. High-altitude building accessories are difficult to install, maintain, and install. While this is only a relative improvement, implementing this solution would increase costs. Furthermore, without circuitry and a drive mechanism like a motor, sprinkler control would be difficult.

[0007] 3. The existing nozzles realize automatic rotation of the nozzles through impeller blades. For example, by tilting the blades, the vertical water flow impacts the tilted blades to create a circumferential component of force, thereby causing the blades to rotate. However, this technical solution can only achieve rotation in one direction and cannot achieve rotation in two directions. For high-altitude nozzles, it is often only necessary to spray obliquely upwards; similar to ground nozzles, they also need to rotate to expand the spraying area and reduce the number of nozzles.

[0008] 4. When the blades of the prior art nozzle rotate, the blades generally rotate too fast. In the swing mechanism for swinging, the swing period needs to be controlled. It is inappropriate to swing too fast. However, there is no solution in the prior art.

[0009] 5. The nozzle piping system of the existing technology will cause water to accumulate in the nozzle after the water supply is cut off. Even if there is water tension, it is impossible to return water in time before the water valve is closed. If the water cannot be returned in time, there will be dripping after the water valve is closed, which will cause unexpected situations. Summary of the Invention

[0025] The beneficial effects of the present invention are:

[0026] 1. Regarding the first point raised in the background technology, when the size of the nozzle is similar to that of the main pipeline, it is ensured that there is enough space inside the nozzle to realize the function and improve efficiency; at the same time, in order to achieve pressure control, multiple openings are set in the nozzle, and the opening size is smaller than the inner diameter of the nozzle to control the flow rate, so that the pressure will not enter the upstream nozzle, and the pressure between the upstream and downstream nozzles is achieved.

[0027] 2. Regarding the second point raised in the background technology, the traditional solution of setting up an additional power source or manually controlling the rotation of the sprinkler head is abandoned. Water flow is used to realize the automatic movement of the sprinkler head. A more stable mechanical structure is used to replace the power structure and wire layout, avoiding the difficulty of high-altitude maintenance.

[0028] 3. Regarding the third point raised in the background technology,

[0029] 1) The linear water force is converted into rotational power through the impeller mechanism, and the flow of water on different sides is achieved through the rotation of the impeller. The flow on different sides drives the swing plate to swing back and forth, thereby driving the nozzle to swing within a range of 90 degrees. At the same time, a constant flow path is set to flexibly replenish the water source.

[0030] 2) A pressurized space is formed by the misalignment between the plurality of fan-shaped holes to drive the swing plate to swing.

[0031] 4. Regarding the fourth point raised in the background technology, there are four solutions:

[0032] 1) Cut off the power shaft between the swing mechanism and the power mechanism, so that the rotation speed of the power mechanism is no longer synchronized with the rotation speed of the swing mechanism;

[0033] 2) Add a counterweight - a blade - to the impeller shaft of the blade to reduce the rotation speed of the impeller blade through the weight of the blade;

[0034] 3) By controlling the rotation angle cycle, the swing plate only swings 90 degrees back and forth in one cycle; while the blade rotates 360 degrees in one cycle, so the swing speed is slower than the rotation speed;

[0035] 4) The rotation angle of the blade can be flexibly adjusted to adjust the circumferential force component.

[0036] 5. Regarding point 5 of the background technology, a baffle is provided to block the water flow at a lower water level outside the internal components of the nozzle to avoid dripping.
