Description

Technical Field

[0001] This invention relates primarily to the field of flagpole technology, and more particularly to a flagpole that is easy to erect and lay down. Background Technology

[0002] In certain scenarios, flagpoles need to be able to be erected and lowered as needed, and these scenarios include, but are not limited to, ships.

[0003] Shipboard flagpoles, both bow and stern, are typically selected according to relevant specifications and standards as tilting flagpoles. Serving as carriers for flags, mast lights, anchor lights, and other equipment, they are an essential component of naval vessels. Currently, raising and lowering shipboard flagpoles is primarily done manually, generally requiring multiple people working together, which is time-consuming and labor-intensive. Furthermore, operation requires personnel on deck, which is inconvenient in inclement weather and poses safety hazards. Therefore, through in-depth research and development, the inventors have provided a flagpole that can be electrically powered to achieve both uprighting and lowering. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a flagpole that is easy to erect and lay down.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A flagpole that is easy to erect and fall includes a base fixed to an external platform, the base being hinged to the bottom end of a main pole, the main pole being connected to an electric drive mechanism that drives the main pole to flip in a plane perpendicular to the external platform.

[0007] As a further improvement to the above technical solution:

[0008] The base includes a pair of hinge seats fixed to the external platform. The bottom end of the main rod is formed with a hinge shaft along the direction perpendicular to the length of the main rod. The hinge shaft passes through the hinge seat to form a hinge.

[0009] The electric drive mechanism is fixed to the external platform. The electric drive mechanism includes a drive motor and a transmission assembly. The output end of the drive motor is connected to the input end of the transmission assembly, and the output end of the transmission assembly is fixed to the hinge shaft via a coupling.

[0010] The transmission assembly includes a T-type reducer and a worm gear reducer; the first input end of the T-type reducer is connected to the output end of the drive motor, the second input end of the T-type reducer is connected to the rotary handle, the output end of the T-type reducer is connected to the input end of the worm gear reducer, the first output end of the worm gear reducer is fixed to the hinge shaft via a coupling, and the second output end of the worm gear reducer is fitted with an observation rod for indicating the tilt angle of the main rod.

[0011] The flagpole also includes two symmetrically arranged diagonal braces, the upper end of which is hinged to the middle of the main pole and the lower end of which is hinged to the external platform.

[0012] The diagonal brace is composed of multiple brace segments hinged end to end, and adjacent diagonal braces are provided with locking mechanisms to fix their relative positions.

[0013] The diagonal brace includes a first brace and a second brace connected end to end; the locking mechanism includes a locking hole formed at the first end of the first brace and a locking electric cylinder built into the tail end of the second brace; the output shaft of the locking electric cylinder can be inserted into the locking hole to fix the relative position of the first brace and the second brace.

[0014] The flagpole also includes a signal transmitter, which is connected to the electric drive mechanism and the locking cylinder respectively. When the electric drive mechanism drives the main pole to rotate to be perpendicular to the external platform, the signal transmitter sends a locking command to the locking cylinder, thereby causing the output shaft to extend and insert into the locking hole.

[0015] The diagonal bracing includes a first bracing and a second bracing connected end-to-end via a fisheye connector; the locking mechanism includes a limiting shaft at the first end of the first bracing and a connecting plate at the second end of the second bracing. The connecting plate has a groove and is equipped with a locking motor for pushing a stop block to close the groove; when the first bracing and the second bracing are parallel, the limiting shaft engages with the groove, and the locking motor fixed on the connecting plate drives the stop block to close the groove, thereby fixing the relative positions of the first bracing and the second bracing.

[0016] The flagpole also includes a signal transmitter, which is connected to the electric drive mechanism and the locking motor respectively. When the electric drive mechanism drives the main pole to rotate to be perpendicular to the external platform, the signal transmitter sends a locking command to the locking motor, thereby driving the anti-reverse block to close the slot.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] By incorporating an electric drive mechanism connected to the main mast, electrical energy can be used to rotate the main mast, enabling its erection and lowering without manual operation. Compared to existing technologies that rely on manual rotation of the main mast, the electric drive is more efficient and eliminates the need for personnel to work on the deck, thus reducing safety risks.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figures 1 to 5 As shown, the flagpole of this embodiment, which is easy to erect and lower, includes a base 2 fixed on an external platform 1. The base 2 is hinged to the bottom end of the main pole 3. The main pole 3 is connected to an electric drive mechanism 4, which drives the main pole 3 to rotate in a plane perpendicular to the external platform 1. The base 2 is fixed on the external platform 1. In this embodiment, the flagpole is installed on a ship, so the external platform 1 is the deck. The base 2 has a U-shaped groove, and the main pole 3 is hinged in the U-shaped groove. When the main pole 3 is perpendicular to the external platform 1, the side wall of the main pole 3 fits against the inner wall of the U-shaped groove. That is, when the main pole 3 is fully erected, the base 2 can use the U-shaped groove to provide support for the main pole 3 in three directions and prevent it from tipping over. By setting the electric drive mechanism 4 connected to the main pole 3, the main pole 3 can be rotated using electrical energy, thereby realizing the erection and lowering of the main pole 3 without manual operation. Compared to existing technologies that rely on manual rotation of the main mast 3, electric drive is more efficient and can eliminate the need for workers to go up on the deck, thereby reducing safety risks.

[0029] In this embodiment, the base 2 includes a pair of hinge seats 21 fixed to the external platform 1. A hinge shaft 31 is formed at the bottom end of the main rod 3 along a direction perpendicular to its length. The hinge shaft 31 passes through the hinge seats 21 to form a hinge. The two hinge seats 21 are arranged opposite each other, with the main rod 3 located between them. The bottom end of the main rod 3 has a hinge shaft 31 perpendicular to its body, and both ends of the hinge shaft 31 pass through the two hinge seats 21 respectively, thereby hinged the main rod 3 to the base 2.

[0030] In this embodiment, the electric drive mechanism 4 is fixed to the external platform 1. The electric drive mechanism 4 includes a drive motor 41 and a transmission assembly 42. The output end of the drive motor 41 is connected to the input end of the transmission assembly 42, and the output end of the transmission assembly 42 is fixed to the hinge shaft 31 via a coupling 5. The transmission assembly 42 includes a T-type reducer 421 and a worm gear reducer 422. The first input end of the T-type reducer 421 is connected to the output end of the drive motor 41, the second input end of the T-type reducer 421 is connected to the rotary handle 6, and the output end of the T-type reducer 421 is connected to the input end of the worm gear reducer 422. The first output end of the worm gear reducer 422 is fixed to the hinge shaft 31 via a coupling 5, and the second output end of the worm gear reducer 422 is fitted with an observation rod 7 for indicating the tilt angle of the main rod 3. The drive motor 41 and the T-type reducer 421 are both fixedly installed below the external platform 1, and the worm gear reducer 422 is fixedly installed above the external platform 1. The output end of the drive motor 41 is connected to the first input end of the T-type reducer 421, and the output end of the T-type reducer 421 is connected to the input end of the worm gear reducer 422. The first output end of the worm gear reducer 422 is fixed to the hinge shaft 31 via the coupling 5. The force is output from the drive motor 41 and transmitted to the hinge shaft 31 through the T-type reducer 421 and the worm gear reducer 422, thereby driving the hinge shaft 31 to rotate. Since the hinge shaft 31 is formed at the bottom of the main rod 3 and is perpendicular to the main rod 3 body, it can drive the main rod 3 to rotate around the central axis of the hinge shaft 31. Specifically, the worm gear reducer 422 has a reverse locking function. When the main rod 3 rotates to a state perpendicular to the external platform 1, it cannot rotate in the reverse direction without active driving, thus preventing accidental tipping. Furthermore, to address power outages, the second input end of the T-type reducer 421 is connected to the rotary handle 6. In the absence of power, the operator can manually rotate the rotary handle 6 from below the deck, causing the T-type reducer 421 and the worm gear reducer 422 to rotate, thereby allowing the main rod 3 to stand upright or bend. Even further, the second output end of the worm gear reducer 422 is fitted with an observation rod 7 to indicate the tilt angle of the main rod 3. This observation rod 7 rotates with the shaft of the worm gear reducer 422, allowing the operator to determine the angle of the main rod 3 based on the tilt angle of the observation rod 7. It should be noted that the drive motor 41, the T-type reducer 421, and the worm gear reducer 422 are all commercially available products, and their structure, connection, and working principle are existing technologies, which will not be elaborated upon here.

[0031] In this embodiment, the flagpole also includes two symmetrically arranged diagonal bracing rods 8. The upper end of the diagonal bracing rod 8 is hinged to the middle of the main pole 3, and its lower end is hinged to the external platform 1. By setting two diagonal bracing rods 8, and symmetrically arranging the two diagonal bracing rods 8 on both sides of the main pole 3, diagonal support can be provided to the main pole 3 from two directions, thereby improving the anti-collapse ability of the main pole 3.

[0032] In this embodiment, the diagonal brace 8 is composed of multiple brace segments 81 hinged end to end, and adjacent diagonal brace segments 8 are provided with locking mechanisms 82 for fixing their relative positions. The diagonal brace 8 includes a first brace 811 and a second brace 812 connected end to end; the locking mechanism 82 includes a locking hole 821 formed at the first end of the first brace 811 and a locking electric cylinder 822 built into the tail end of the second brace 812; the output shaft 8221 of the locking electric cylinder 822 can be inserted into the locking hole 821, thereby fixing the relative positions of the first brace 811 and the second brace 812. The output shaft 8221 of the locking electric cylinder 822 faces the end face of the second diagonal support rod 812, and this end face is recessed inward to form a locking hole 821 that matches the output shaft 8221. When the first support rod 811 and the second support rod 812 are parallel, the output shaft 8221 of the locking electric cylinder 822 extends and can be inserted into the locking hole 821, thereby locking the first support rod 811 and the second support rod 812. By setting a multi-section diagonal support rod 8, when the main pole 3 falls, the first support rod 811 and the second support rod 812 bend and retract, thereby saving space. The flagpole also includes a signal transmitter, which is connected to the electric drive mechanism 4 and the locking electric cylinder 822 respectively. When the electric drive mechanism 4 drives the main pole 3 to rotate to be perpendicular to the external platform 1, the signal transmitter sends a locking command to the locking electric cylinder 822, thereby causing the output shaft 8221 to extend and be inserted into the locking hole 821. By incorporating a signal transmitter into the flagpole, the erection and tilting of the main pole 3 can be linked to the locking and loosening of the diagonal brace 8, thereby simplifying manual operation. It should be noted that the signal transmitter is a commercially available product, and its structure, connection method, and function are all existing technologies, which will not be elaborated upon here.

[0033] In this embodiment, the flagpole also includes a collapsible support 9 mounted on the external platform 1 to support the main pole 3. By providing the collapsible support 9, the upper part of the main pole 3 in the collapsed state can be supported, thereby preventing it from falling directly onto the deck and causing collision or friction damage.

[0034] Example 2

[0035] like Figure 6As shown, the second embodiment of the flagpole of the present invention, which is convenient for erection and lowering, is basically the same as that of the first embodiment, except that: in this embodiment, the diagonal support 8 includes a first support 811 and a second support 812 connected end to end by a fisheye connector 813; the locking mechanism 82 includes a limiting shaft 823 disposed at the first end of the first support 811 and a connecting plate 824 disposed at the second end of the second support 812. The connecting plate 824 has a groove 8241 formed on it and a locking motor 826 installed thereon for pushing the anti-reverse block 825 to close the groove 8241; when the first support 811 and the second support 812 are parallel, the limiting shaft 823 is engaged in the groove 8241. At this time, the locking motor 826 fixed on the connecting plate 824 drives the anti-reverse block 825 to close the groove 8241, thereby fixing the relative position of the first support 811 and the second support 812. Specifically, the connecting plate 824 also has a waist hole, and the anti-reverse block 825 is connected to a handle passing through the waist hole. In the event of a power failure, the operator can move the anti-reverse block 825 through the handle. The flagpole also includes a signal transmitter, which is connected to the electric drive mechanism 4 and the locking motor 826. When the electric drive mechanism 4 drives the main pole 3 to rotate to be perpendicular to the external platform 1, the signal transmitter sends a locking command to the locking motor 826. By including a signal transmitter in the flagpole, the uprighting and tilting of the main pole 3 can be linked with the locking and loosening of the diagonal brace 8, thereby simplifying manual operation. It should be noted that the signal transmitter is a commercially available product, and its structure, connection form, and function are all existing technologies, which will not be described in detail here.

[0036] It should be noted that while ships are selected as the application scenario in the specific implementation, this does not mean that the scope of application of this application is limited to ships.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
