Description

Technical Field

[0001] The present application relates to the field of lifting devices, and in particular to a flag raising system. Background Art

[0002] The flag-raising system usually consists of basic components such as flagpole, flag rope, and flag hoist. The flagpole is the supporting core of the flag-raising system, usually made of durable metal or composite materials. Its height and stability determine the effect of the flag display. The flag rope is used to connect the flag to the lifting device (or manual flag raising). It is usually made of strong fiber or nylon material and has the ability to withstand wind and external tension. The flag itself is usually made of soft and sturdy fabric, and its design and size are customized according to the needs of flag raising. The flag hoist is used to adjust the raising and lowering of the flag manually or automatically. Common flag hoists include manual lifting devices and electric flag hoists.

[0003] In the prior art, during the flag-raising process, when the wind is insufficient, the flag cannot flutter naturally, which directly affects the flag-raising effect. The fluttering of a flag is not only a display of its physical state, but also has important symbolic meaning and ritual sense. When a flag is not fluttering, it tends to appear droopy or stiff, which has a poor visual effect and may make the flag-raising occasion look dull and rigid, weakening its solemn atmosphere. Especially in some solemn celebrations or formal occasions, the fluttering of a flag is usually an important element to express respect, unity and honor. Summary of the invention

[0004] To this end, the present application provides a flag-raising system to solve the problem in the prior art that the flag is difficult to fly when the wind is insufficient.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A flag-raising system comprises a platform, a flagpole connected to the platform, two pulleys rotatably connected to the two ends of the flagpole, a flag rope connected between the two pulleys, a flag connected to the flag rope, and a driving member connected to a receiving cavity of the platform and used for driving the pulley close to the platform to rotate, the flag is connected to the flag rope through a supporting member, an air pump is arranged in the receiving cavity of the platform, a ventilation hose is connected between the air pump and the supporting member, the supporting member is provided with an airflow cavity connected to the ventilation hose, and the outer wall of the supporting member is provided with a plurality of airflow holes connected to the airflow cavity, so that the airflow ejected from the airflow holes can blow up the flag.

[0007] Optionally, the driving member includes a first motor connected to the cavity wall of the accommodating cavity and a driving chain connected to the output shaft of the first motor, the driving chain is wound around the pulley, and a winding assembly for winding the ventilation hose is also provided in the accommodating cavity.

[0008] Optionally, the winding assembly includes a second motor connected to the cavity wall of the accommodating cavity and a winding drum connected to the output shaft of the second motor and used to partially wind the ventilation hose, the end of the ventilation hose away from the support member is wound out of the winding drum and connected to the air pump, the air pump is connected to the walking device, and the walking device includes a support plate connected to the air pump, a plurality of driving wheels rotatably connected to the support plate, and a third motor connected to the support plate and used to drive the driving wheels to rotate;

[0009] The flag-raising system further includes a controller disposed in the accommodating cavity, and the first motor, the second motor, the third motor and the air pump are all electrically connected to the controller.

[0010] Optionally, a first through hole connected to the accommodating cavity and used to cooperate with the driving chain is opened on the top of the platform, and a second through hole connected to the accommodating cavity and used to cooperate with the ventilation hose is opened on the top of the platform;

[0011] The cavity wall of the accommodating cavity is connected with a plurality of guide wheels for partially winding the ventilation hose to guide the moving direction of the ventilation hose, and the plurality of guide wheels are located between the second through hole and the winding drum.

[0012] Optionally, the plurality of air flow holes are distributed along the length direction of the support member, and the plurality of air flow holes are distributed on both sides of the flag.

[0013] Optionally, the support member is connected to a plurality of clips for clamping the flag rope.

[0014] Optionally, a side wall of the platform is connected to a maintenance door communicating with the accommodating cavity.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] In the flag-raising system of the present application, the driving member drives the pulley near the platform to rotate, and the end of the flag rope is connected and wound around the two pulleys. The rotation of the pulley drives the flag rope to rotate cyclically along the pulley track, so that the flag can be raised and lowered. With the driving of the driving member, the support member moves up and down along the height direction of the flagpole with the rise and fall of the flag rope to maintain the stability of the flag. The support member is connected to the air pump through the connected ventilation hose, and the air pump injects air into the airflow cavity in the support member. The airflow cavity ejects air at a higher speed through a plurality of airflow holes, thereby forming an airflow to blow up the flag and assist the flag to flutter.

[0017] With this design, even when there is no wind, the airflow generated by the air pump can blow the flag so that it always flies. This improves the problem of the traditional flag-raising system where the flag cannot fly when there is insufficient wind. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0029] refer to Figure 1-6 The present application discloses a flag-raising system, comprising a platform 1, a flagpole 2 connected to the platform 1, two pulleys 3 rotatably connected to the two ends of the flagpole 2, a flag rope 4 connected between the two pulleys 3, a flag 5 connected to the flag rope 4, and a driving member 8 connected to a receiving cavity 11 of the platform 1 and used for driving the pulley 3 close to the platform 1 to rotate, the flag 5 is connected to the flag rope 4 through a supporting member 6, an air pump 10 is arranged in the receiving cavity 11 of the platform 1, a ventilation hose 7 is connected between the air pump 10 and the supporting member 6, the supporting member 6 is provided with an airflow cavity 61 connected to the ventilation hose 7, and a plurality of airflow holes 62 connected to the airflow cavity 61 are arranged on the outer wall of the supporting member 6, so that the airflow ejected from the airflow holes 62 can blow up the flag 5.

[0030] In the flag-raising system of the present application, the driving member 8 drives the pulley 3 near the platform 1 to rotate, and the ends of the flag rope 4 are connected and wound around the two pulleys 3. The rotation of the pulley 3 drives the flag rope 4 to rotate along the track of the pulley 3, so that the flag 5 can be raised and lowered. With the driving of the driving member 8, the support member 6 moves up and down along the height direction of the flagpole 2 with the rise and fall of the flag rope 4, maintaining the stability of the flag 5. The support member 6 is connected to the air pump 10 through the connected ventilation hose 7, and the air pump 10 injects air into the airflow cavity 61 in the support member 6. The airflow cavity 61 ejects air at a higher speed through a plurality of airflow holes 62, thereby forming an airflow to blow up the flag 5 and assist the flag 5 to flutter.

[0031] Through this design, even in the absence of wind, the airflow generated by the air pump 10 can blow the flag 5 so that it always keeps flying, thereby improving the problem that the flag 5 cannot fly when there is insufficient wind in the traditional flag-raising system.

[0032] The driving member 8 includes a first motor (not shown in the figure) connected to the cavity wall of the accommodating cavity 11 and a driving chain 81 connected to the output shaft of the first motor. The driving chain 81 is wound around the pulley 3. A winding assembly 9 for winding the ventilation hose 7 is also provided in the accommodating cavity 11.

[0033] The rotation of the first motor driving chain 81 drives the pulley 3 to rotate, so that the flag rope 4 synchronously follows the movement of the pulley 3 and rises and falls. The pulley 3 is simultaneously wound with the flag rope 4 and the driving chain 81. The lifting and lowering of the flag rope 4 drives the support member 6 to rise and fall along the height direction of the flagpole 2 through the rotation of the pulley 3;

[0034] In order to prevent the ventilation hose 7 from being pulled or entangled during the lifting process, a winding assembly 9 for winding the ventilation hose 7 is also provided in the accommodating chamber 11. The winding assembly 9 can adjust the length of the ventilation hose 7 as the support 6 is lifted and lowered, thereby preventing the ventilation hose 7 from being wound or damaged due to the change of tension during the lifting process, ensuring that the air supply is stable and undisturbed. The design of the winding assembly 9 ensures that the ventilation hose 7 always maintains an appropriate length, neither dragging on the ground nor getting tangled together due to being too long or hindering the normal operation of the flag-raising system.

[0035] In some embodiments, the pulley 3 driving the platform 1 is provided with two annular grooves, which are used to wind the flag rope 4 and the driving chain 81 respectively.

[0036] The winding assembly 9 includes a second motor (not shown in the figure) connected to the cavity wall of the accommodating cavity 11 and a winding drum (not shown in the figure) connected to the output shaft of the second motor (not shown in the figure) and used to partially wind the ventilation hose 7, the end of the ventilation hose 7 away from the support member 6 is wound out of the winding drum and connected to the air pump 10, the air pump 10 is connected to the walking device 101, and the walking device 101 includes a support plate connected to the air pump 10, a plurality of driving wheels (not shown in the figure) rotatably connected to the support plate, and a third motor (not shown in the figure) connected to the support plate and used to drive the driving wheels to rotate;

[0037] The flag raising system further includes a controller disposed in the accommodating chamber 11 , and the first motor, the second motor, the third motor and the air pump 10 are all electrically connected to the controller.

[0038] The controller is remotely controlled through a terminal device (such as a mobile phone or a computer) so that the first motor, the second motor, the third motor and the air pump 10 work together. During the flag-raising process, the controller can adjust the first motor to drive the pulley 3 near the platform 1 to rotate, thereby driving the flag rope 4 to rise and fall; the second motor drives the winding drum to rotate, partially winding the ventilation hose 7, and ensuring that the length of the ventilation hose 7 is automatically adjusted as the support 6 rises and falls. In this way, the ventilation hose 7 can always maintain an appropriate length to avoid affecting the flag-raising process due to stretching or winding; at the same time, the air pump 10 is connected to the support plate of the walking device 101 and provides airflow to the ventilation hose 7. The walking device 101 includes a plurality of driving wheels rotatably connected to the support plate and a third motor. The third motor is responsible for driving the driving wheel to rotate, thereby driving the walking device 101 to reciprocate along the set trajectory in the accommodating cavity 11. As the ventilation hose 7 is wound, the reciprocating motion of the air pump 10 and the walking device 101 can ensure that the ventilation hose 7 will not be pulled or entangled during the winding process, and maintain the stability of the air supply.

[0039] It should be noted that the third motor drives any combination of the plurality of driving wheels to rotate, and the movement mode of the walking device 101 can be flexibly adjusted according to actual needs.

[0040] The top of the platform 1 is provided with a first through hole 12 connected to the accommodating cavity 11 and used to cooperate with the driving chain 81, and the top of the platform 1 is provided with a second through hole 13 connected to the accommodating cavity 11 and used to cooperate with the ventilation hose 7;

[0041] A plurality of guide wheels 102 for partially winding the ventilation hose 7 are connected to the cavity wall of the accommodating cavity 11 to guide the moving direction of the ventilation hose 7. The plurality of guide wheels 102 are located between the second through hole 13 and the winding drum.

[0042] The plurality of guide wheels 102 are located in the accommodating cavity 11, between the second through hole 13 and the winding drum, and play a role in guiding the moving direction of the ventilation hose 7. The plurality of guide wheels 102 are reasonably arranged to ensure that the ventilation hose 7 maintains a smooth movement path during the lifting process, and avoids friction between the hose and the hole wall or other parts of the second through hole 13. If the ventilation hose 7 rubs against these parts, it will not only increase the friction resistance, but also may cause damage to the hose or poor airflow, affecting the airflow supply during the flag-raising process, and further affecting the display effect of the flag 5.

[0043] The plurality of airflow holes 62 are distributed along the length direction of the support member 6, and the plurality of airflow holes 62 are distributed on both sides of the flag 5. Through this arrangement, the airflow holes 62 can evenly spray airflow to the flag 5 from both sides of the support member 6, so that the flag 5 always keeps flying during the lifting process. The even distribution of airflow can effectively prevent the flag 5 from partially drooping or incompletely unfolding due to insufficient airflow; the airflow is ejected from the plurality of airflow holes 62, forming an airflow covering both sides of the flag 5, which assists the flag 5 in unfolding and maintaining its stable state.

[0044] In some embodiments, the flag 5 can be fixedly connected to the support member 6 along the length direction of the support member 6; in some other embodiments, the flag 5 can also be tied to the support member 6 by means of ropes or the like.

[0045] The support member 6 is connected with a plurality of clips for clamping the flag rope 4 .

[0046] The support member 6 is connected with a plurality of clips for clamping the flag rope 4, and these clips are spaced apart along the length direction of the support member 6 to ensure that the flag 5 can be stably fixed on the flag rope 4 during the lifting process. With this design, the support member 6 can realize the replacement or adjustment of the flag 5, so that the flag 5 can be disassembled and replaced as needed, which is convenient for maintenance and cleaning.

[0047] In some embodiments, the support member 6 may be a cylinder or a rectangle.

[0048] It should be noted that the clip is a prior art and will not be described in detail in this application.

[0049] In some embodiments, the support member 6 may also be fixedly connected to the flag rope 4 .

[0050] The side wall of the platform 1 is connected with an inspection door communicating with the accommodating chamber 11. When the inspection door is opened, the user can easily enter the accommodating chamber 11 to replace or repair the first motor, the second motor, the third motor, the air pump 10 and other components therein.

[0051] In some embodiments, steps may be provided on both sides of the platform 1 .

[0052] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0053] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
