Description

Technical Field

[0001] This utility model relates to the field of natural gas production technology, and in particular to a device for indicating wind direction. Background Technology

[0002] In industrial sites involving flammable and explosive gases, such as natural gas pressurization stations, wind vanes are typically installed in open areas to ensure production safety and timely emergency response. As an important meteorological indicator, the wind vane displays real-time wind direction and assists in judging wind speed. By observing its swaying motion, it visually indicates the current wind direction, providing clear wind guidance for on-site personnel. Especially in emergencies such as natural gas leaks, wind direction information becomes crucial for determining the diffusion path of leaked gas, rationally planning evacuation areas, and formulating effective emergency measures. Furthermore, by observing the amplitude and frequency of the wind vane's swaying, workers can roughly estimate the wind speed and thus assess the diffusion rate of the leaked gas, providing important reference for emergency decision-making.

[0003] However, wind vanes are exposed to a complex outdoor environment for extended periods, facing numerous adverse factors. Ultraviolet radiation, wind and rain erosion, corrosive gases, and mechanical wear can all cause varying degrees of damage. These factors can lead to aging and fading of the wind vane material, reduced strength, and even tearing, severely impacting its visibility and the accuracy of wind direction indication. Therefore, to ensure the proper functioning of wind vanes, they need to be replaced regularly.

[0004] Currently, wind vanes are typically installed at the top of a wind vane, which is inserted into a sleeve fixed to the ground. Replacing a wind vane requires first pulling the wind vane out of the sleeve, then laying it flat on the ground, removing the damaged or old wind vane, installing a new one, and finally re-erecting the wind vane and inserting it back into the sleeve. This process is cumbersome and complex, and due to the height and weight of the wind vane, it often requires two people working together. Therefore, the current wind vane installation method suffers from inconvenience and low replacement efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of inconvenient operation and low efficiency of wind direction bag replacement in the existing technology, and to provide a device for indicating wind direction.

[0006] This utility model provides a device for indicating wind direction, comprising:

[0007] A column and a slide rail, wherein the slide rail is fixed on the column and is arranged along the height direction of the column;

[0008] A slide bar, which is mounted in the slide rail;

[0009] A wind vane is connected to a slide bar via a connecting rod. The slide bar can move along the slide rail, thereby causing the wind vane to move along the height direction of the column.

[0010] This invention provides a device for indicating wind direction. The upright column serves as the frame of the entire device, fixing it to the ground. A slide rail is arranged along the height of the upright column, providing a channel for the sliding rod to move up and down along the column. The sliding rod can move along the slide rail, and the wind direction bag is connected to the slide rod via a connecting rod. Therefore, the slide rod can move the wind direction bag along the slide rail, thus enabling the wind direction bag to move between the top and bottom of the upright column. When the wind direction bag needs to be replaced, it can descend from the top of the upright column to the bottom, the old wind direction bag can be removed, and a new wind direction bag can be installed. The new wind direction bag can then rise back to the top of the upright column. The cooperation of the slide rail and the sliding rod allows the wind direction bag to move up and down along the upright column, simplifying the wind direction bag replacement process and improving its efficiency.

[0011] The sliding rod can move along the slide rail in two ways: First, an electric gear can be mounted on the sliding rod, and a rack adapted to the electric gear can be mounted on the slide rail. The sliding rod moves up and down along the slide rail by the rolling of the electric gear along the rack. Alternatively, a traction rope can be used, fixed to the top of the sliding rod. Tightening and loosening the traction rope allows the sliding rod to move up and down along the slide rail.

[0012] Preferably, the system also includes a lifting rope. A pulley system is provided at the top of the column, and a winding wheel is provided at the bottom of the column. The two ends of the lifting rope are connected to the sliding rod and the winding wheel, respectively. The middle portion of the lifting rope is wound around the pulley system. Rotating the winding wheel allows the sliding rod to move along the slide rail via the lifting rope. The lifting rope is used to pull the sliding rod. One end of the lifting rope is connected to the sliding rod, and the other end is connected to the winding wheel after passing through the pulley system at the top of the column. The forward and reverse rotation of the winding wheel tightens or releases the lifting rope, thereby driving the sliding rod to move vertically up and down along the column. The pulley system changes the direction of force on the lifting rope during this process, ensuring that the traction force is effectively transmitted to the sliding rod. Compared to the electric gear method, this solution has a simpler structure, lower cost, and is easier to maintain.

[0013] Preferably, the winding reel is provided with a handle. The handle is used to rotate the winding reel, making it easier and faster to operate the winding reel in both directions.

[0014] Preferably, the pulley system includes a first fixed pulley and a second fixed pulley, which are arranged at the same height. The first fixed pulley is located directly above the winding sheave, and the second fixed pulley is located directly above the sliding rod. In this configuration, the first fixed pulley being located directly above the winding sheave allows the force direction of the lifting rope connected between the first fixed pulley and the winding sheave to change from a vertical direction to a horizontal direction. The second fixed pulley being located directly above the sliding rod allows the force direction of the lifting rope connected between the first fixed pulley and the second fixed pulley to change from a horizontal direction to a vertical direction.

[0015] Preferably, the slide bar is made of ferromagnetic material, a magnetic control device is installed on the column, and a magnetic control switch is installed at the bottom of the column. The magnetic control switch can control the magnetic control device to open or close, and the opening of the magnetic control device can limit the movement of the slide bar through magnetic attraction.

[0016] When the magnetic control device is in the active state, it exerts a magnetic attraction on the sliding rod; when the magnetic control device is in the inactive state, this magnetic attraction disappears. This design ensures that when the sliding rod moves to the height of the magnetic control device, its magnetic attraction will hold it in place, preventing it from falling due to gravity even after the lifting rope is released, thus effectively preventing accidental falls. When the wind direction bag needs to be replaced and the sliding rod needs to be lowered, simply operate the magnetic control switch to switch the magnetic control device from the active state to the inactive state, releasing the fixation on the sliding rod and allowing it to descend smoothly.

[0017] The magnetic control device can be a mechanical magnetic control device or an electromagnetic magnetic control device. A mechanical magnetic control device directly or indirectly controls the distribution, direction, or intensity of the magnetic field through mechanical structures (such as gears, connecting rods, cams, etc.). An electromagnetic magnetic control device controls the generation, distribution, or change of the magnetic field through electrical signals (current, voltage), without requiring mechanical movement.

[0018] Preferably, the magnetic control device is a mechanical magnetic control device. Compared with electromagnetic magnetic control devices, mechanical magnetic control devices have a simpler structure, lower cost, and do not require electricity, thus saving on electricity costs.

[0019] Preferably, the column is a hollow structure, and the magnetic control device is located on the inner wall of the hollow structure. This design utilizes the external structure of the column to conceal and protect the magnetic control device, preventing it from aging and being damaged by sun and rain, thereby helping to extend the service life of the magnetic control device.

[0020] Preferably, the column is fixed to the ground by a base. This design effectively enhances the stability of the column.

[0021] Preferably, the connection between the wind direction bag and the connecting rod is detachable. This design facilitates the replacement of the wind direction bag.

[0022] The detachable connection method can be a locking connection, a snap-on connection, or a magnetic connection.

[0023] Preferably, the detachable connection is a snap-fit ​​connection or a magnetic connection. Compared to a locking connection, the snap-fit ​​connection and the magnetic connection are more convenient to install and remove. Snap-fit ​​and magnetic connections further improve the efficiency of changing the wind direction bag.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This utility model provides a device for indicating wind direction. Through the cooperation of the slide rail and the slide rod, the wind direction bag can be driven to move up and down along the column, which not only simplifies the operation process of replacing the wind direction bag, but also improves the replacement efficiency of the wind direction bag.

[0050] Figure 2 A front view of a device for indicating wind direction is shown, in which the connecting rod 4, wind direction bag 5, magnetic control device 10, and magnetic switch 11 are not shown. Figure 2 As shown in the image.

[0051] like Figures 1 to 3 As shown, a device for indicating wind direction includes a column 1, a slide rail 2, a slide bar 3, and a wind direction bag 5.

[0052] The slide rail 2 is fixed to the column 1 and is arranged along the height of the column 1. Specifically, the height of the column 1 is 5m to 7m, the top of the slide rail 2 is 20cm to 30cm lower than the top of the column 1, and the bottom of the slide rail 2 is 0.5m to 1m higher than the ground.

[0053] The slide rod 3 is installed in the slide rail 2. Specifically, the length of the slide rod 3 is 0.6m to 1m.

[0054] The wind vane 5 is connected to the slide bar 3 via a connecting rod 4. The slide bar 3 can move along the slide rail 2, thereby moving the wind vane 5 along the height direction of the column 1. Specifically, the connecting rod 4 is horizontally arranged, with a length of 0.5m to 1m, and is connected to the top of the slide bar 3.

[0055] In an optional embodiment, a lifting rope 8 may also be included. A pulley assembly 6 is provided at the top of the column 1, and a winding wheel 7 is provided at the bottom of the column 1. The two ends of the lifting rope 8 are connected to the sliding rod 3 and the winding wheel 7, respectively, and the middle portion of the lifting rope 8 is wound around the pulley assembly 6. Specifically, the pulley assembly 6 is installed 10cm below the top of the column 1. The winding wheel 7 is positioned 0.8m to 1m above the ground and is connected to the outer wall of the column 1 via a connecting rod. The lifting rope 8 can be a nylon rope or a steel wire rope. The diameter of the winding wheel 7 can be 15cm to 25cm. The lifting rope 8 can be wound around the winding wheel 7.

[0056] In an optional embodiment, the winding wheel 7 may be provided with a handle 701. The winding wheel 7 can be rotated in the forward or reverse direction by rotating the handle 701.

[0057] In an optional embodiment, the pulley block 6 may include a first fixed pulley and a second fixed pulley. The first fixed pulley and the second fixed pulley are arranged at the same height, with the first fixed pulley located directly above the winding wheel 7 and the second fixed pulley located directly above the sliding rod 3. Specifically, the lifting rope 8 starts from the winding wheel 7, extends vertically upward to the first fixed pulley, changes direction after passing through the first fixed pulley, and then extends horizontally. Next, the lifting rope 8 continues to extend to the second fixed pulley, changes direction again after passing through the second fixed pulley, and then extends vertically downward, finally connecting to the top of the sliding rod 3. The diameter of both the first fixed pulley and the second fixed pulley can be 5cm to 10cm. Both the first fixed pulley and the second fixed pulley are connected to the outer wall of the column 1 via connecting rods.

[0058] In an optional embodiment, the slide bar 3 can be made of ferromagnetic material, a magnetic control device 10 can be installed on the column 1, and a magnetic control switch 11 can be installed at the bottom of the column 1. The magnetic control switch 11 can control the magnetic control device 10 to open or close. When the magnetic control device 10 is open, it can limit the movement of the slide bar 3 through magnetic attraction. Specifically, the installation range of the magnetic control device 10 matches the area corresponding to when the slide bar 3 moves to the highest point of the slide rail 2. The slide bar 3 can be made of iron or steel, or other materials that can be attracted by magnets.

[0059] When the slide bar 3 moves to the highest point of the slide rail 2, the magnetic control device 10 is activated. At this moment, the magnetic control device 10 can restrict the movement of the slide bar 3 through magnetic attraction, thereby achieving the effect of fixing the slide bar 3.

[0060] Specifically, when the length of the slide bar 3 is 0.8m, the number of magnetic control devices 10 can be two, installed at positions 0.2m and 0.6m lower than the highest point of the slide rail 2, respectively.

[0061] In an optional embodiment, the magnetic control device 10 can be a mechanical magnetic control device. Specifically, the magnetic control switch 11 is connected to the magnetic control device 10 via a mechanical linkage or wire rope to control the opening or closing of the magnetic control device 10.

[0062] In an optional embodiment, the column 1 can be a hollow structure, with the magnetic control device 10 located on the inner wall of the hollow structure. Specifically, the cross-sectional shape of the column 1 can be square or circular. A through hole of a size matching the magnetic control device 10 can be formed between the outer wall of the column 1 and the slide rail 2. The magnetic control device 10 can be installed in the through hole, and the installed magnetic control device 10 will not protrude beyond the inner wall of the slide rail 2, thereby avoiding interference with the normal movement of the slide rod 3. In this way, the installation position of the magnetic control device 10 can be closer to the slide rod 3, thus more effectively using magnetic attraction to fix the slide rod 3.

[0063] In an optional embodiment, the column 1 can be fixed to the ground by the base 9. Specifically, the base 9 is a steel plate structure, and the base 9 is anchored to the concrete structure below the ground by bolts or steel bars. The column 1 and the base 9 are connected by welding or bolts.

[0064] In an optional embodiment, the connection between the wind direction bag 5 and the connecting rod 4 can be a detachable connection.

[0065] In an optional embodiment, the detachable connection can be a snap-fit ​​connection or a magnetic connection. The wind direction bag 5 includes a wind bag and a connecting rope. The first end of the connecting rope is connected to the wind bag, and the second end of the connecting rope is used to set a snap-fit ​​or magnetic structure for easy connection with the connecting rod 4. Specifically, a female snap-fit ​​and a female snap-fit ​​can be respectively set on the second end of the connecting rod 4 and the connecting rope, or two magnets that can attract each other can be respectively set on the second end of the connecting rod 4 and the connecting rope.

[0066] Example 2

[0067] This embodiment describes the method of using a wind direction indicator device as described in Embodiment 1. When it is necessary to replace the wind direction bag 5, the specific operation includes the following steps:

[0068] S1: Operate the magnetic switch 11 to change the magnetic control device 10 from the on state to the off state. At this time, the magnetic attraction of the magnetic control device 10 to the slide bar 3 will disappear.

[0069] S2: Rotate the winding wheel 7 using handle 701 to release the lifting rope 8. Under its own weight, the slide bar 3 moves downward along the slide rail 2, thereby pulling the wind direction bag 5 down as well.

[0070] S3: When the wind direction bag 5 descends to a height of 1m to 1.5m above the ground, remove the worn-out wind direction bag 5 from the connecting rod 4 and replace it with a new wind direction bag 5.

[0071] S4: By rotating the winding wheel 7 in the opposite direction using handle 701, the lifting rope 8 is tightened, and the slide bar 3 moves upward along the slide rail 2 under the traction of the lifting rope 8. When the slide bar 3 moves to the highest point of the slide rail 2, the rotation of the winding wheel 7 stops.

[0072] S5: Operate the magnetic control switch 11 to change the magnetic control device 10 from the closed state to the open state. At this time, the magnetic control device 10 fixes the slide bar 3 through magnetic attraction, completing the replacement of the wind direction bag 5.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
