Description

Technical Field

[0001] The utility model relates to the technical field of clamps for building construction, in particular to an installation device for a non-contact monitoring terminal of a power transmission line. Background Art

[0002] At present, due to the current technical conditions, the transmission line non-contact fault monitoring terminal sensor needs to be installed roughly parallel to the ground in order to obtain better sensor data. Therefore, the same type of transmission line non-contact fault monitoring terminal is commonly installed on the cross arm on the high-voltage tower, and the terminal box and the cross arm angle steel are firmly clamped by the angle steel installation clamp and bolts. In general, it can meet the installation requirements of most transmission line high-voltage towers. Due to the different voltage levels of high-voltage transmission lines across the country, the structural forms of high-voltage towers vary greatly. Some angle steel towers have cross arm angle steels, while some do not, or there is no suitable matching cross arm for the height of the tower to be installed. Especially for transmission lines with voltage levels of 110KV and below, due to the reduction of the design standards of the tower-type bearing structure, the tower structure is often simplified. The frame part of the special tower type is directly fixed with angle steel inclined cross connection, and the horizontal reinforcement of the second-level and above cross arm angle steel is cancelled. Or due to the limitation of the sensor detection distance, the tower height suitable for installation does not have a suitable cross arm angle steel, and the conventional installation device cannot meet the installation requirements. This makes it difficult for existing conventional installation devices to adapt to the installation requirements of all on-site pole towers. Utility Model Content

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0049] See also Figure 1 The utility model provides an installation device for a non-contact monitoring terminal for a power transmission line, which is characterized by comprising:

[0050] A first mounting clamping plate (1), used for mounting and fixing the mounting device on the angle steel of the tower through the first mounting clamping plate;

[0051] A first bracket (2), the first bracket (2) being fixedly connected to the first mounting clamping plate (1), and an angle adjustment plate (3) being fixed on the first bracket (2);

[0052] A second bracket (4), the second bracket (4) is used to fix a non-contact monitoring terminal (6) connected to a power transmission line, and an angle connection plate (5) is fixed on the second bracket (4);

[0053] The angle adjustment plate (3) has an arc-shaped opening for adjusting the installation angle of the angle connection plate (5) when it is installed and fixed with the angle connection plate (5), thereby adjusting the relative angle between the monitoring terminal (6) and the first bracket (2).

[0054] The monitoring terminal is fixed on the second bracket, which is in turn fixed to the first bracket. The first bracket is fixed to the angle steel via a first mounting clamp. According to the actual inclination angle of the angle steel, the monitoring terminal is kept roughly parallel to the ground through an angle adjustment connection between the angle connection plate (5) and the angle adjustment plate (3).

[0055] The utility model designs an angle-adjustable installation device that satisfies both reliability and installation convenience. It can be installed on an inclined non-transverse angle steel and keep the monitoring terminal roughly parallel to the ground. Figure 2-3As shown. It can be applied not only to conventional angle steel poles and towers, but also to special angle steel poles and towers, especially to poles with angle steel inclined cross-connection structures. It has wide adaptability and can realize the effective installation and application of monitoring terminals under all-scenario installation conditions. It fundamentally solves the core technical demands such as the inability of terminals to collect data due to limited on-site installation.

[0056] Furthermore, the angle adjustment plate (3) comprises a mounting surface and an adjustment surface which are perpendicular to each other;

[0057] The mounting surface is used for fixed connection with the first bracket (2);

[0058] The adjustment surface is provided with an arc-shaped opening;

[0059] The arc-shaped opening comprises a first arc groove (31) and a second arc groove (32) having the same center;

[0060] The angle connection plate (5) is provided with first connection holes (51) arranged in an arc shape;

[0061] The first bolt (33) passes through the first arc groove (31) to connect to the corresponding first connection hole (51), and the second bolt (34) passes through the second arc groove (52) to connect to the corresponding first connection hole (51), thereby realizing the connection between the angle adjustment plate (3) and the angle connection plate (5).

[0062] Specifically, the center angle of the first arc groove (31) is less than 90 degrees.

[0063] Specifically, the center angle of the second arc groove (31) is less than 90 degrees.

[0064] Specifically, in the actual process, a first bolt (33) is used to connect a corresponding first connection hole (51) in the first arc groove (31). The specific first connection hole (51) to be connected is determined according to the actual adjustment angle.

[0065] Specifically, in the second arc groove (32), a second bolt (34) is used to connect to a corresponding first connection hole (51). The specific first connection hole (51) to be connected to is determined according to the actual adjustment angle.

[0066] Furthermore, the first bracket (2) has a second connection hole (21), the second bracket (4) has a third connection hole (41), and the common center of the first circular arc groove (31) and the second circular arc groove (32) corresponds to the second connection hole (21);

[0067] The first bracket (2) and the second bracket (4) are fixed by passing a third bolt (22) through the second connection hole (21) and the third connection hole (41).

[0068] The two aforementioned arc grooves, each of which corresponds to a first connecting hole, are connected by a bolt. At the same time, in order to make the first bracket and the second bracket more stable, and to make the angle adjustment plate and the angle connecting plate more stable after the angle adjustment, the first bracket and the second bracket are directly connected by a third bolt. Since the common center of the first arc groove (31) and the second arc groove (32) corresponds to the second connecting hole (21), that is, the common center of the first arc groove (31) and the second arc groove (32) and the straight line formed between the second connecting hole (21) and the circular surface formed by the first arc groove (31) and the second arc groove (32) are perpendicular, so that under various angle adjustments, the second connecting hole and the third connecting hole can be aligned without deviation to achieve fixed connection.

[0069] Furthermore, the first mounting clamping plate (1) is composed of a first straight plate, a second straight plate and a U-shaped plate connected between the first straight plate and the second straight plate;

[0070] The U-shaped plate is used to cover the angle steel of the tower;

[0071] The first straight plate and the second straight plate are fixed to the first bracket (2) by means of fourth bolts (23).

[0072] The first mounting clamp (1) is an angle steel mounting clamp, and the U-shaped plate is conveniently put on the angle steel to achieve a fixed connection between the mounting device and the angle steel. Furthermore, one of the side plates of the U-shaped plate is provided with a through hole, and the fifth bolt (11) passes through the through hole to clamp the U-shaped plate and the tower angle steel.

[0073] Generally, the distance between the two side plates of the U-shaped plate is greater than the thickness of the angle steel. If they are not fixed and clamped, the mounting device and the angle steel bracket are prone to loosening and unstable installation. Therefore, a fifth bolt (11) is provided, and the head of the fifth bolt (11) presses the angle steel tightly against the side plate of the U-shaped plate without a through hole to achieve clamping.

[0074] Furthermore, at least two first mounting clamping plates (1) are fixedly connected to the first bracket (2).

[0075] The additional first mounting clamping plate (1) makes the connection between the mounting device and the angle steel more stable.

[0076] Furthermore, the monitoring terminal (6) is fixed on the second bracket (4) via at least two second mounting clamps (7).

[0077] Furthermore, the angle adjustment range between the angle connecting plate (5) and the angle adjustment plate (3) is 0-130 degrees.

[0078] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
