Description

Technical Field

[0001] The present invention relates to an intelligent flagpole, in particular to a sliding air outlet sealed intelligent flagpole. Background Art

[0002] Since ancient times, the flag has always been a symbol of the cohesion and centripetal force of the masses. In today's era, peace has become the theme of the era's development. From countries and various departments at all levels to primary and secondary schools or various large-scale sports games, etc., flag-raising and flag-lowering ceremonies have become essential activities for people, and the flagpole is an essential carrier for the flag to flutter. Usually, raising, lowering the flag or maintaining the flag at a certain height can basically be completed. However, we can see that often due to the influence of meteorological conditions such as lack of natural wind, the flag cannot unfold and flutter, especially in the middle and lower parts of the flagpole, the flag rarely unfolds and flutters; when the flag is raised, lowered or at a set height, due to the continuous change of the natural wind direction, the flag often gets entangled on the flagpole and cannot unfold and flutter gracefully. In the case of no wind or gentle breeze, the flag cannot unfold and flutter well. If such a situation occurs during a major event, it is quite regrettable. Most people have the same feeling and hope for a change. The applicant has also applied for a flagpole with automatic air supply before, which supplies air through an air flow pipe and an air outlet cylinder. However, the layout of the air flow pipe and the air outlet cylinder is relatively complex and easy to be damaged, and the applicability is poor. Summary of the Invention

The flagpole body passes through the flagpole base and is sealed and fixed at the bottom of the flagpole base. A blowing device is arranged at the bottom of the flagpole body. An air outlet is arranged longitudinally on the flagpole body, and a sealing device is arranged at the air outlet; the flag keel moves up and down along the air outlet, and the sealing device is in an open state at the position where the flag keel contacts the air outlet.

[0005] The technical solution of the present invention is further limited in that the air outlet is sealed by cascaded sliding pieces, and the flag keel is arranged at the opening and closing contact point in the center of the cascaded sliding pieces; the cascaded sliding pieces are divided into left and right pieces, the middle of the two pieces is the contact point for controlling opening and closing, and a movable pulley is arranged at the bottom of each piece.

[0006] Further, the air outlet is sealed by left and right rubber sealing strips, and the flag keel moves up and down along the center of the rubber sealing strips.

[0007] Furthermore, the pneumatic device further includes an intelligent control system, and a wind speed measuring instrument is provided at the top of the flagpole body. The wind speed measuring instrument is connected to the signal input port of the intelligent control system, and the signal output port of the intelligent control system is connected to the air blowing device.

[0008] Furthermore, a counterweight disk is also arranged on one side of the flagpole body corresponding to the flag.

[0009] Furthermore, an LED strong light and a high-definition camera are arranged in the hemispherical seat at the top end of the flagpole body.

[0010] Beneficial effects: The sliding open-air vent sealed intelligent flagpole provided by the present invention is sealed by cascaded sliding sheets.

[0011] Figure 1 is a structural schematic diagram of a sealed automatic air-supplementing flagpole provided by the present invention;

[0012] Figure 2 is a structural schematic diagram of the cascaded sliding sheets provided by the present invention. Detailed Embodiments

[0013] The technical solution of the present invention will be described in detail below with reference to the drawings, but the protection scope of the present invention is not limited to the described embodiments.

[0014] Embodiment 1: The present invention provides a sliding open-air vent sealed intelligent flagpole, and its structural schematic diagram is as Figure 1 shown, including a flagpole body 1 and a flagpole base 2. The flagpole body 1 passes through the flagpole base 2 and is sealed and fixed at the bottom of the flagpole base 2. A blower device 3 is arranged at the bottom of the flagpole body 1. An air outlet is arranged longitudinally on the flagpole body 1. The wind from the blower device 3 is blown out through the air outlet to keep the flag flying in the wind.

[0015] In order to save wind power and enhance the sealing performance in this embodiment, a sealing device is arranged at the air outlet. The flag keel 5 moves up and down along the air outlet. At the position where the flag keel 5 contacts the air outlet, the sealing device is in an open state.

[0016] In this embodiment, the air outlet is sealed by cascaded sliding sheets 6. The structural schematic diagram of the cascaded sliding sheets 6 is as Figure 2 shown. The cascaded sliding sheets 6 are divided into left and right arranged segments 8. The middle of the two segments 8 is a contact point 7 for controlling opening and closing. A moving pulley 9 is arranged at the bottom of each segment 8.

[0017] The flag keel is arranged at the opening and closing contact 7 in the center of the sliding piece 6 of the cascade. When the flag rises or falls, the keel touches the opening and closing contact 7, and the shards 8 separate left and right to form an air outlet, from which the air of the air blowing device 3 blows out to keep the flag flying.

[0018] The pneumatic device also includes an intelligent control system, and an anemometer is arranged at the top of the flagpole body. The anemometer is communicated with the signal input port of the intelligent control system, and the signal output port of the intelligent control system is communicated with the blower. The intelligent control calculates the rotation speed of the blower according to the wind speed measured by the anemometer and the gas flow required for the flag to fly normally.

[0019] N = K * S * V * [Q]

[0020] In the formula, N is the rotation speed of the blower; K is the coefficient obtained by converting the absolute pressure of the gas; S is the cross-sectional area of the air outlet at the flag position, which is a pre-stored value in the intelligent system; [V] is the difference between the wind speed measured by the anemometer and the wind speed required for the flag to fly normally; [Q] is the data table of the flow pressure difference rotation speed relationship provided by the blower manufacturer.

[0021] On the side of the flagpole body corresponding to the flag, a counterweight plate is also configured. An LED strong light and a high-definition camera are arranged in the hemispherical seat at the top of the flagpole body for shooting.

[0022] According to the above solution, it can be realized that the flag can always face the wind direction, and under the action of internal air flow compensation, the flag always maintains a state of flying against the wind under a certain wind force; when the flag rises, falls or maintains a certain height, the flag always has a dynamic flying; the flag reflects the supreme honor and pride of a group's spirit, energy and morale, giving people a personal touch and shock in the heart. If the flag being raised is the national flag or the flag of a large sports event, it will produce extraordinary effects.

[0023] Embodiment 2: The present invention provides a sliding open-air outlet sealed intelligent flagpole, whose structure and working principle are the same as those of Embodiment 1, and the difference is that: the air outlet is sealed by rubber sealing strips that are joined together left and right, and the flag keel 5 moves up and down along the center of the rubber sealing strips. By sealing the air outlet with rubber sealing strips, the structure is simpler, the cost is low, and it is convenient for popularization and promotion.

[0024] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined by the appended claims.
