Description

Technical Field

[0001] The utility model belongs to the technical field of meteorological devices, in particular to an isolation device for a meteorological wind measuring tower. Background Art

[0002] When the lightning rod of the meteorological wind tower is struck by lightning, the current passes through the lightning rod at the top of the tower and the wind direction and speed sensor mounting bracket installed on the top of the tower - the wind cross arm, and is transmitted to the wind direction and speed sensors at both ends of the wind cross arm, causing the electronic components inside the two sensors to be broken down and damaged, resulting in the scrapping of the sensors. At the same time, the current is transmitted along the sensor cables (signal lines, power lines, shielded grounding wires) to the ground connected to the power supply system, wind observation data collector and supporting business computers, causing breakdown, burnout and other lightning disasters, which have a serious impact on meteorological observation business. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the above-mentioned technology and provide a meteorological wind tower isolation device.

[0004] To this end, the utility model provides a meteorological wind measurement tower isolation device, including a nesting piece and a snap-fit ​​piece. The nesting piece is used to be sleeved on the plug-in piece of the wind cross arm, and the snap-fit ​​piece cooperates with the nesting piece and is fixed on the wind cross arm; both the nesting piece and the snap-fit ​​piece are fixedly provided with insulating bakelite inside, and the insulating bakelite is arranged around the wind cross arm; both the nesting piece and the snap-fit ​​piece are provided with matching mounting plates for snap-fitting between the nesting piece and the snap-fit ​​piece, and the end of the nesting piece is fixedly connected with a copy plug-in piece.

[0005] Furthermore, isolation grooves are provided on both sides of the nesting member and the engaging member, and a plurality of drainage holes are provided on the lower surface of the isolation grooves.

[0006] Furthermore, the matching diameters of the nesting member and the engaging member are larger than the diameter of the wind cross arm, so that a gap is left between the nesting member, the engaging member and the wind cross arm.

[0007] Furthermore, the length of the nesting piece is shorter than the length of the engaging piece, and the nesting piece and the engaging piece are made of stainless steel.

[0008] Furthermore, a water retaining eave is provided at the edge of the engaging piece which is joined with the nesting piece.

[0009] The utility model provides a meteorological wind tower isolation device, which has the following beneficial effects:

[0010] The device physically isolates the wind cross arm by wrapping and splicing at the connection of the wind cross arm, ensuring that when the tower is struck by lightning, the current will be released through the tower to the ground and will not be transmitted through the wind cross arm to the sensor and collection equipment to cause damage.

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0018] like Figure 1-3 As shown, the utility model provides a meteorological wind tower isolation device, including a nesting member 1 and a snap-fit ​​member 2, wherein the nesting member 1 is used to be sleeved on the plug-in member 9 of the wind cross arm 10, and the snap-fit ​​member 2 cooperates with the nesting member 1 and is fixed on the wind cross arm 10. Both the nesting member 1 and the snap-fit ​​member 2 are fixedly provided with insulating bakelite 3 inside, and the insulating bakelite 3 is arranged around the wind cross arm 10. Both the nesting member 1 and the snap-fit ​​member 2 are provided with matching mounting plates 7 for snap-fitting and fixing between the nesting member 1 and the snap-fit ​​member 2. A duplicate plug-in member 4 is fixedly connected to the end of the nesting member 1. Because the plug-in member 9 is wrapped and covered by the nesting member 1, the subsequent assembly of the wind cross arm 10 is ensured by adding an identical duplicate plug-in member 4.

[0019] like Figure 4 5, the two sides of the nesting member 1 and the engaging member 2 are provided with an isolation groove 5, and the lower surface of the isolation groove 5 is provided with a plurality of drainage holes 6. The isolation groove 5 can ensure that in rainy weather, the water on the wind cross arm 10 forms a water accumulation area after entering the nesting member 1 and the engaging member 2, and then the water is discharged through the drainage holes 6.

[0020] The length of the nesting member 1 is less than that of the engaging member 2. The nesting member 1 and the engaging member 2 are made of stainless steel and have a long service life. Figure 3As shown, the matching diameter of the nesting member 1 and the clamping member 2 is larger than the diameter of the wind cross arm 10, so that a gap of 1 cm is left between the nesting member 1, the clamping member 2 and the wind cross arm 10. Leaving a gap can prevent the nesting member 1, the clamping member 2 from directly contacting the wind cross arm 10, and prevent the material of the nesting member 1 and the clamping member 2 from affecting the lightning protection effect.

[0021] like Figure 5 As shown, a water retaining eave 8 is also provided at the edge where the clamping member 2 is joined with the nesting member 1. The water retaining eave 8 can reduce water leakage at the joined edge and improve the sealing performance. After the nesting member 1 and the clamping member 2 are installed on the wind cross arm 10, a layer of insulating glue is applied to the joined edge to ensure the overall sealing performance.

[0022] The device physically isolates the wind cross arm 10 by wrapping and splicing at the connection of the wind cross arm 10, ensuring that when the tower is struck by lightning, the current will be released through the tower to the ground and will not be transmitted through the wind cross arm 10 to the sensor and collection equipment to cause damage.

[0023] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
