Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, in particular to a liftable golf net mechanism. Background Art

[0002] Golf nets are used to isolate the golf course from the outside environment, preventing balls from flying off the course. These nets are often erected at high altitudes. When winds are strong, the nets are impacted by the wind and transmitted to the pillars. This can reduce the net's service life over time and may even cause the pillars to collapse, posing a safety hazard. To address this, some liftable net mechanisms have emerged on the market. However, these mechanisms are often exposed to the sun and rain, resulting in high maintenance costs. Furthermore, they lack precise control over the height of the net, making them unsuitable for practical applications. Summary of the Invention

[0003] In view of the above situation, it is necessary to provide a liftable golf fence mechanism to solve the problems of high maintenance cost and inaccurate lifting height of the existing golf fence lifting mechanism due to long-term exposure to open air environment.

[0004] To achieve the above-mentioned object, the technical solution of the present invention is as follows: a liftable golf fence mechanism, comprising: a control platform, a wind measurement module, a fence, and a plurality of pillars with accommodating cavities, wherein the plurality of pillars are arranged at intervals and vertically installed on the ground;

[0005] A lifting mechanism for controlling the height of the fence is provided inside the pillar. The control platform is connected to the wind measurement module and the lifting mechanism respectively. The wind measurement module is located at the top of the pillar.

[0006] The lifting mechanism includes a winch, a stroke calculation device and a pulley block. A steel wire is wound on the winch. The stroke calculation device is used to calculate the length of the steel wire when the winch is working.

[0007] The free end of the steel wire is wound around the stroke calculating device and the pulley block and passes through the top of the support column to be connected to the top of the fence, and the bottom of the fence is fixed on the ground.

[0008] In the liftable golf fence mechanism of the present invention, a through hole for passing the steel wire is provided on the top of the support column, a guide mechanism is provided on the top of the support column, and the through hole is located in the guide mechanism;

[0009] The guide mechanism includes a guide groove and several guide wheels arranged in the guide groove. One end of the guide groove extends to the outside of the pillar and is suspended in the air. The suspended part of the guide groove is open to the ground. The steel wire passes through the through hole, passes through several guide wheels, and then passes through the opening of the guide groove to connect to the top of the fence.

[0010] In the liftable golf fence mechanism of the present invention, the lifting mechanism further comprises a base, and the winch and the stroke calculation device are respectively fixed on the base;

[0011] The pulley group includes a first pulley and a second pulley. The first pulley is fixed on the base, and the second pulley is fixed on the inner wall of the pillar and located above the winch. After the free end of the steel wire is wound out from the winch, it is first stretched to the second pulley, and then pulled back to the first pulley and the stroke calculation device.

[0012] In the liftable golf fence mechanism of the present invention, the heights of several pillars are different. The pillars near the middle are the highest, and the heights of the pillars on both sides of the middle decrease successively, so that the line connecting the top ends of several pillars is a convex arc shape. The wind measurement module is located near the top of the highest group of pillars.

[0013] The liftable golf fence mechanism of the present invention also includes several guide ropes. The fence is provided with several buckles. One end of the guide rope is fixed to the support near the top, and the other end passes through the buckle and is fixed to the ground through a ground anchor.

[0014] In the liftable golf fence mechanism of the present invention, the fence includes a plurality of net ropes, which are fixed to the ground through ground anchors.

[0015] In the liftable golf fence mechanism of the present invention, the control platform is communicatively connected with the wind measuring module and the lifting mechanism respectively via the RS485 bus.

[0016] In the liftable golf fence mechanism of the present invention, the control platform includes a control mainboard and an operation panel; the operation panel is a touch screen for controlling the working state of the device and for displaying status information such as wind speed and fence height.

[0017] In the liftable golf fence mechanism of the present invention, a door body is provided on the support column near the bottom.

[0018] Through the above technical solution, the beneficial effects of the present invention are:

[0019] 1. The present invention can avoid exposure to the sun and rain by arranging the lifting mechanism inside the pillar, thereby increasing the service life of the lifting mechanism and reducing maintenance costs. At the same time, since the lifting mechanism is independently arranged inside each pillar, the voltage is more stable during operation and the lifting height of each pillar is more accurate.

[0020] 2. During the lifting and lowering process of the fence, the winch works to release or retract the steel wire to adjust the height of the fence. Through the setting of the stroke calculation device, the length of the released or retracted steel wire can be accurately calculated so that the lifting and lowering height of the fence can meet the precise requirements.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following further describes a liftable golf fence mechanism of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the present invention and are not intended to limit the present invention.

[0029] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top," "bottom," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to simplify the description of the present invention. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Please refer to Figure 1-6A raise / lower golf fence mechanism includes: a control platform, a wind measurement module, a fence 100, and several pillars 200 with accommodating cavities. The pillars 200 are spaced apart and vertically mounted on the ground. A lifting mechanism for controlling the height of the fence is installed within the pillars 200. The control platform is in communication with the wind measurement module and the lifting mechanism, respectively. The wind measurement module is located on the top of the pillars 200. The lifting mechanism includes a hoist 300, a stroke calculation device 400, and a pulley assembly. Optionally, the hoist 300 can be replaced by a traction device such as a winch. A steel wire 500 is wound around the hoist 300. The stroke calculation device 400 is used to calculate the length of the steel wire 500 traveled during operation of the hoist 300. The free end of the steel wire 500 is wound around the stroke calculation device 400 and the pulley assembly, and then extends from the top of the pillars 200 to connect to the top of the fence 100. The bottom of the fence 100 is fixed to the ground. It is understood that a cable can be buried underground to power the lifting mechanism. Preferably, the travel calculation device 400 can be a meter or other device capable of measuring the length of the wire 500. The meter is used in conjunction with a meter wheel and a sensor. The measurement coefficient is the circumference of the wheel, i.e., the length of one rotation of the wheel. The meter accumulates the wheel's circumference each time the wheel strikes the sensor during rotation.

[0031] During operation, the wind measurement module can measure wind speed or wind pressure and transmit this information back to the control platform. The control platform adjusts the height of the pillars 200 based on the current wind pressure and the height information of the pillars 200, thereby achieving the raising and lowering of the fence 100. Specifically, when the fence 100 is raised, the winch 300 rotates forward, causing the steel wire 500 to be retracted. Since the top of the fence 100 is connected to the steel wire 500, the fence 100 can be raised during the retraction process of the steel wire 500. When the fence 100 is lowered, the winch 300 rotates reversely, causing the steel wire 500 to be released, and the fence 100 connected to the steel wire 500 to be lowered as the steel wire 500 is released.

[0032] Existing seine lifting mechanisms often calculate the height of the seine 100 by the number of turns of the winch, a method that is subject to significant inaccuracy. Since the outer diameter of the winch's turntable changes with the number of turns of the steel wire 500, it is understandable that each turn of the winch increases or decreases the length of the steel wire 500 on the winch. For example, for a five-meter descent, the winch is set to make fifty turns. However, since the length of the steel wire 500 varies with each turn and cannot be calculated, the actual descent height is subject to significant error, and it is impossible to guarantee that the descent height will be exactly five meters after fifty turns. Therefore, using the number of turns of the winch as the calculation for the height of the seine 100 is inaccurate. In the present invention, by winding the steel wire 500 around the stroke calculation device 400, the length of the steel wire 500 released or recovered can be accurately calculated, achieving the required precision in the height of the seine 100. Furthermore, by locating the lifting mechanism inside the support 200, this technical solution protects the lifting mechanism from exposure to sunlight and rain, extending its service life and reducing maintenance costs. At the same time, since each pillar 200 is independently provided with a lifting mechanism, the voltage is more stable during operation, and the lifting height of each pillar 200 is more precise, meeting the market's requirements for the accuracy of the network lifting mechanism.

[0033] Please refer to Figure 3 In this embodiment, a through hole 210 is provided at the top of the support 200 for the steel wire 500 to pass through. A guide mechanism 600 is also provided at the top of the support 200, with the through hole 210 located within the guide mechanism 600. The guide mechanism 600 includes a guide slot 610 and several guide wheels 620 disposed within the guide slot 610. One end of the guide slot 610 extends to the outside of the support 200 and is suspended in the air. The suspended portion of the guide slot 610 is open to the ground. The steel wire 500 passes through the through hole 210, passes through the guide wheels 620, and then exits the open portion of the guide slot 610 to connect to the top of the fence 100. The guide mechanism 600 provides traction for the steel wire 500, better protecting it while also facilitating smoother raising and lowering of the fence 100. Furthermore, the guide mechanism 600 shields the through hole 210, preventing rainwater from seeping into the support 200 during rain, causing water accumulation and potentially malfunctioning the lifting mechanism.

[0034] Please refer to Figure 1In this embodiment, the lifting mechanism further includes a base 700, on which the hoist 300 and the stroke calculation device 400 are respectively fixed. The pulley group includes a first pulley 800 and a second pulley 900. The first pulley 800 is fixed to the base 700. Preferably, three sets of first pulleys 800 are provided, which can effectively pull the steel wire 500. The second pulley 900 is provided in one set. The second pulley 900 is fixed to the inner wall of the pillar 200 and is located above the hoist 300. A fixing bar 910 for mounting the second pulley 900 extends laterally from the inner wall of the pillar 200. Specifically, the first pulley 800 and the second pulley 900 each include a column and a pulley. One end of the column is connected to the pulley via a rotating shaft. The pulley is provided with a groove for winding the steel wire 500. After being wound from the hoist 300, the free end of the steel wire 500 is first stretched to the second pulley 900 and then pulled back to the first pulley 800 and the stroke calculation device 400, so that the release and recovery of the steel wire 500 can be smoother during the lifting process. Preferably, the stroke calculation device 400 is installed between the two sets of first pulleys 800.

[0035] Please refer to Figure 4 In this embodiment, the several pillars 200 are of varying heights, with the pillars 200 near the center being the tallest and the pillars 200 on either side of the center gradually decreasing in height. This creates a convex arc shape connecting the tops of the pillars 200, giving the fence 100 an overall convex arc shape, adapting to the mainstream design of golf fences. A wind measurement module is located near the top of the tallest set of pillars 200.

[0036] Preferably, sixteen groups of pillars 200 are provided, the four pillars in the middle are of the same height of 45m, and the heights of the pillars 200 on both sides of the middle decrease successively, namely 40m, 35m, 30m, 25m, 20m, and 15m.

[0037] Furthermore, the wind force is divided into three levels. The default wind speed of level 0 to 7 is less than 62km / h, the wind speed of level 7 to 8 is 62-74km / h, the wind speed of level 8 to 9 is 75-88km / h, the wind speed of level 9 to 10 is 89-102km / h, and the wind speed above level 10 is greater than 102km / h.

[0038] When the wind force is within the range of 0 to 7, all the pillars 200 are raised to the maximum height, that is, the fence 100 reaches the maximum height; when the wind force is within the range of 7 to 8, the fence 100 connected to the 45m and 40m pillars 200 are lowered by 8m and 5m respectively; when the wind force is within the range of 8 to 9, the fence 100 connected to the 45m, 40m and 35m pillars 200 are uniformly lowered to a height of 30m; when the wind force is within the range of 9 to 10, the fence 100 connected to all the pillars 200 are uniformly lowered to a height of 20m; when a typhoon approaches with a wind force above level 10, the fence 100 connected to all the pillars 200 are uniformly lowered to the ground.

[0039] The above is only an embodiment. When used, the number and height of the pillars 200 can be selected and customized according to the specific site environment conditions. The number and height of the pillars 200 are not limited here.

[0040] Please refer to Figure 5-6 In this embodiment, the fence 100 also includes several guide ropes 110. Several buckles 120 are provided on the fence 100. One end of the guide rope 110 is secured to the top of the pillar 200, while the other end passes through the buckle 120 and is secured to the ground via a ground anchor 111. This arrangement prevents the fence 100 from flapping during strong winds, enhancing its stability. Furthermore, the buckles 120 allow the fence 100 to be raised and lowered along the guide ropes 110. Preferably, the guide ropes 110 are made of steel wire.

[0041] Please refer to Figure 2 , Figure 5-6 In this embodiment, the fence 100 includes several ropes 130, which are fixed to the ground via anchors 111 to prevent the bottom of the fence 100 from being blown away by the wind. Specifically, the ropes 130 are spaced and arranged parallel to each other on the fence 100. When the fence 100 is suspended, the ropes 130 are perpendicular to the ground. Preferably, buckles 120 are installed at intervals on the ropes 130 to ensure that the overall force of the fence 100 is more stable when encountering wind. Specifically, the fence 100 and the ropes 130 can be made of nylon.

[0042] In this embodiment, the control platform is connected to the wind measurement module and the lifting mechanism via the RS485 bus. The RS485 bus uses balanced transmission and differential reception to achieve communication: the transmitting end converts the TTL level signal of the serial port into two differential signal outputs, a and b. After cable transmission, the differential signal is restored to a TTL level signal at the receiving end. Since the transmission line usually uses a twisted pair and is differentially transmitted, it has a strong ability to resist common-mode interference. The bus transceiver is highly sensitive and can detect voltages as low as 200mV, so the transmission signal can be restored from a distance of one kilometer. Compared with wireless communication, it has a strong anti-interference ability and is lower in cost than base station communication.

[0043] In this embodiment, the control platform includes a control board and an operating panel. The operating panel is a touchscreen display used to control the device's operating status and display information such as wind speed and fence height. When the golf fence mechanism is in operation, manual or automatic mode can be selected on the operating panel, and the corresponding heights of the pillars 200 can be set at various wind speed levels. The control board includes a function model that shows the relationship between the height and wind level.

[0044] In this embodiment, a door (not shown in the figure) is provided near the bottom of the pillar 200 to facilitate installation and maintenance of the lifting mechanism inside the pillar 200.

[0045] In summary, the present invention provides a liftable golf fence mechanism, comprising: a control platform, a wind measurement module, a fence 100 and a plurality of pillars 200 with accommodating cavities, wherein the plurality of pillars 200 are arranged at intervals and vertically mounted on the ground; a lifting mechanism for controlling the height of the fence 100 is provided in the pillars 200, and the control platform is communicatively connected with the wind measurement module and the lifting mechanism respectively, and the wind measurement module is disposed on the top of the pillars 200; the lifting mechanism comprises a winch 300, a stroke calculation device 400 and a pulley block, a steel wire 500 is wound on the winch 300, and the stroke calculation device 400 is used to calculate the length of the steel wire 500 when the winch 300 is working; the free end of the steel wire 500 is wound around the stroke calculation device 400 and the pulley block and passes through the top of the pillar 200 to be connected to the top of the fence 100, and the bottom of the fence 100 is fixed to the ground. By wrapping the steel wire 500 around the stroke calculation device 400, the length of the wire 500 released or retracted can be accurately calculated, enabling the fence 100 to be raised or lowered to the required precision. Furthermore, the lifting mechanism is located within the pillars 200, protecting it from direct sunlight and rain, extending its service life and reducing maintenance costs. Furthermore, since each pillar 200 has its own independent lifting mechanism, the voltage is more stable during operation, and the height of each pillar 200 is more precisely adjusted, meeting market requirements for precision in net lifting mechanisms.
