Abstract
Description
Technical Field
[0001] This utility model relates to a wind vane steering device for chemical enterprises, belonging to the field of wind vane technology. Background Technology
[0002] In the event of a hazardous chemical leak at a chemical plant, the toxic and harmful substances will flow downwind, where their concentration will be relatively higher. To minimize harm from these substances, plant employees and nearby residents should evacuate against the wind, i.e., upwind. At this time, accurately locating a wind vane at a high position can help people determine their direction.
[0003] However, the existing wind vane's hanging rod and bottom support rod are fixedly connected, and the hanging rod cannot rotate. During use, the wind vane often gets tangled on the hanging rod and cannot adjust itself according to the wind direction. Its sensitivity is poor, and sometimes it cannot accurately indicate the wind direction, which can lead to safety accidents. Utility Model Content
[0004] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a wind vane steering device for chemical enterprises, which has high sensitivity and can avoid the situation where the wind vane gets tangled in steel pipes.
[0005] The wind vane steering device for chemical enterprises described in this utility model includes a chassis, an outer support pipe fixed on top of the chassis, an inner pipe rotatably connected inside the outer support pipe, a connecting ring fixed at the top of the inner pipe, and the inner pipe being movably connected to the wind vane through the connecting ring; a support cover is also fitted on the inner pipe, the support cover being located below the connecting ring and closely attached to the connecting ring.
[0006] The technical solution of this utility model is to provide a wind vane turning device for chemical enterprises. By setting a rotatable inner tube, the wind vane can be flexibly rotated according to the wind direction. At the same time, a support cover is set to support the wind vane in the absence of wind, so that it is at a certain angle to the inner tube and away from the inner tube, thereby preventing the wind vane from getting tangled on the inner tube.
[0007] Preferably, the support cover is conical in shape and has several ventilation holes evenly distributed on it to facilitate airflow and avoid affecting natural wind.
[0008] Preferably, a bearing is welded to the top of the outer support tube, and the outer support tube is rotatably connected to the inner tube through the bearing.
[0009] Preferably, a gasket is welded onto the inner tube to support it and prevent it from falling.
[0010] Preferably, the outer support tube is also rotatably connected to a wind cup, which can be used to determine the wind speed.
[0011] Preferably, the wind vane is covered with a luminous sticker for easy observation at night.
[0012] Preferably, the outer support tube is evenly distributed with several reinforcing supports, and the bottom of the reinforcing supports is fixedly connected to the chassis.
[0013] The advantages of this utility model compared with the prior art are:
[0014] The wind vane steering device for chemical plants described in this utility model features a rotatable inner tube, allowing the wind vane to rotate flexibly according to the wind direction. A support cover is also included to support the wind vane in calm conditions, keeping it at a certain angle to the inner tube and away from it, thus preventing the wind vane from becoming entangled in the inner tube. This utility model has high sensitivity, avoiding the situation where the wind vane becomes entangled in the steel pipe, extending the service life of the wind vane, and preventing safety accidents caused by the wind vane's inability to accurately indicate the wind direction.

[0018] The present invention will be further described below with reference to specific embodiments.
[0019] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.
[0020] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.
[0021] like Figures 1-2 As shown, this embodiment is achieved through the following technical solution: it includes a chassis 8, which can be fixedly connected to equipment or a building. An outer support pipe 6 is fixed on the top of the chassis 8. The outer support pipe 6 is made of DN20 steel pipe. An inner pipe 10 is rotatably connected inside the outer support pipe 6. The inner pipe 10 is made of DN15 steel pipe. A connecting ring 2 is fixed on the top of the inner pipe 10. The inner pipe 10 is movably connected to the wind vane 1 through the connecting ring 2. A support cover 3 is also fitted on the inner pipe 10. The support cover 3 is located below the connecting ring 2 and is close to the connecting ring 2.
[0022] In this embodiment, the support cover 3 is conical in shape, and has several ventilation holes 11 evenly distributed on it to facilitate airflow and avoid affecting natural wind. A bearing 5 is welded to the top of the outer support tube 6, and the outer support tube 6 is rotatably connected to the inner tube 10 via the bearing 5. A gasket 4 is welded to the inner tube 10 to support it and prevent it from falling. A wind cup 9 is also rotatably connected to the outer support tube 6, allowing for the determination of wind speed. A luminous sticker 12 is affixed to the wind vane 1 for nighttime observation. Several reinforcing supports 7 are evenly distributed on the outer support tube 6, and the bottom of the reinforcing supports 7 is fixedly connected to the chassis 8.
[0023] The working process of this utility model is as follows:
[0024] When there is wind, the wind will blow the wind vane 1 up. When the wind direction changes, the wind vane 1 changes with the wind and at the same time drives the inner tube 10 to rotate through the connecting ring 2.
[0025] When there is no wind, the wind vane 1 falls naturally under the action of gravity. The bottom cable of the wind vane 1 is attached to the support cover 3 and away from the inner tube 10, thereby preventing the wind vane 1 from getting tangled on the inner tube 10.
[0026] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
