Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] Please see Figure 1One embodiment of this application provides an installation device for a power quality monitoring terminal, including a mounting base 100, an adjustment mechanism 200, and a positioning mechanism 300. The mounting base 100 has a through mounting hole 110 and a mounting cavity 120 that are connected to each other. The adjustment mechanism 200 passes through the through mounting hole 110 and is capable of reciprocating along the axial direction of the through mounting hole 110. The positioning mechanism 300 is disposed on the adjustment mechanism 200 and is used to install the power quality monitoring terminal.

[0034] In use, the aforementioned installation device for power quality monitoring terminals involves first installing the power quality monitoring terminal on the positioning mechanism 300. Since the positioning mechanism 300 is connected to the adjustment mechanism 200, when the adjustment mechanism 200 moves along the axial direction of the mounting through hole 110 of the mounting base 100, it can drive the power quality monitoring terminal on the positioning mechanism 300 to move, thereby achieving fine-tuning of the position of the power quality monitoring terminal. Compared with traditional technology, after installing the power quality monitoring terminal using the aforementioned installation device, it is not necessary to remove the entire power quality monitoring terminal from the electrical equipment to fine-tune its position. The adjustment process is simple, improving the installation efficiency of the power quality monitoring terminal.

[0035] As an explanation, the mounting base 100 is used to set up at a designated location on the electrical equipment. After the power quality monitoring terminal is installed on the electrical equipment, in order to avoid interference sources such as strong electromagnetic interference, it is necessary to fine-tune the position of the power quality monitoring terminal. Furthermore, the purpose of fine-tuning is to ensure that the power quality monitoring terminal can operate normally while avoiding interference sources and preventing objects from shielding the wireless signal, thereby reducing the error of the monitoring data.

[0036] In addition to avoiding sources of interference, the power quality monitoring terminal can also be adjusted to a location with better monitoring quality, thereby further improving the monitoring effect of the power quality monitoring terminal.

[0037] exist Figure 1 In the embodiment shown, the axial direction of the mounting through hole 110 is direction B.

[0038] Optionally, the positioning mechanism 300 can use common positioning methods such as snap-fit ​​or adhesive to position the power quality monitoring terminal, which will not be elaborated here.

[0039] Please see Figure 1 In one embodiment, the adjustment mechanism 200 includes an adjustment seat 210, which has a first side 211 and a second side 212 opposite to each other. The first side 211 is located in the mounting cavity 120, and the second side 212 is provided with a limiting part 213. The mounting seat 100 has a mounting part with a mounting through hole 110, and the limiting part 213 is used to abut against the mounting part.

[0040] The limiting part 213 of the second side 212 of the regulating seat 210 can abut against the mounting part with the mounting through hole 110. In this way, it can prevent the regulating mechanism 200 from moving too far along the axial direction of the mounting through hole 110 and disengaging from the mounting through hole 110, thereby limiting the regulating seat 210 and avoiding damage to the power quality monitoring terminal.

[0041] Optionally, the limiting part 213 can be a plurality of limiting blocks spaced apart circumferentially along the second side 212, or it can be a limiting ring arranged circumferentially around the second side 212, as long as it can prevent the adjusting seat 210 from disengaging from the mounting through hole 110, and no specific limitation is made here.

[0042] Furthermore, in one embodiment, the mounting portion is provided with a sidewall of mounting through hole 110 for the mounting base 100.

[0043] Please see Figure 1 In one embodiment, the installation device for the power quality monitoring terminal further includes a first buffer 410 and a second buffer 420. The first buffer 410 is disposed on the mounting portion and is used to abut against the limiting portion 213. The second buffer 420 is disposed on the side wall of the mounting cavity 120 opposite to the mounting through hole 110 and is used to abut against the first side 211.

[0044] With this configuration, when the adjusting mechanism 200 moves along the mounting cavity 120 toward the mounting through hole 110, the first buffer 410 can provide a certain buffer for the limiting part 213, preventing the limiting part 213 from directly contacting the outer periphery of the mounting through hole 110 and causing collision damage. Similarly, when the adjusting mechanism 200 moves along the mounting through hole 110 toward the mounting cavity 120, the second buffer 420 can provide a certain buffer for the first side 211 of the adjusting mechanism 200, preventing the first side 211 of the adjusting mechanism 200 from directly contacting the side wall of the mounting cavity 120 opposite to the mounting through hole 110 and causing collision damage.

[0045] For illustrative purposes, the mounting cavity 120 has a top wall and a bottom wall that are disposed opposite to each other. The top wall of the mounting cavity 120 is the wall surface on the side of the mounting base 100 where the mounting through hole 110 is opened. The first buffer member 410 is disposed on the top wall of the mounting cavity 120, and the second buffer member 420 is disposed on the bottom wall of the mounting cavity 120. These details will not be elaborated here.

[0046] Optionally, the first buffer 410 and the second buffer 420 can be springs, rubber products, or other components, as long as they can provide a buffering effect; no specific limitations are made here.

[0047] Understandably, specifically Figure 1In the embodiment shown, the first buffer 410 and the second buffer 420 are springs.

[0048] Please see Figure 1 In one embodiment, the adjustment mechanism 200 further includes a damper 500. The side wall of the mounting cavity 120 is provided with a guide portion, which extends along the axial direction of the mounting through hole 110. One end of the damper 500 is guided and engaged with the guide portion, and the other end of the damper 500 is connected to the limiting portion 213.

[0049] When the adjusting mechanism 200 reciprocates along the axial direction of the mounting through hole 110, the limiting part 213 can drive the damper 500 to reciprocate in the extension direction of the guide part. Since there will inevitably be a gap between the adjusting mechanism 200 passing through the mounting through hole 110 and the hole wall of the mounting through hole 110, when the mounting base 100 shakes or the power quality monitoring terminal collides with external objects, the adjusting mechanism 200 will be displaced radially along the mounting through hole 110. By setting the damper 500, when the adjusting mechanism 200 moves radially along the mounting through hole 110, it can play a certain buffering role, preventing the force generated between the adjusting mechanism 200 and the hole wall of the mounting through hole 110 from being too large and causing damage.

[0050] Furthermore, the damper 500 can provide a certain degree of shock absorption for the adjustment mechanism 200.

[0051] In one embodiment, the damper 500 includes a damping part, a first connecting rod and a second connecting rod. The opposite ends of the damping part are respectively connected to one end of the first connecting rod and one end of the second connecting rod. The end of the first connecting rod away from the damping part is connected to the limiting part 213, and the end of the second connecting rod away from the damping part is guided and engaged with the guide part.

[0052] Furthermore, the damping part can adopt common damping components such as hydraulic damping components, gas damping components, and friction damping components, without being specifically limited here; preferably, the damping part adopts a spring damper 500, which has a simple structure and low implementation cost.

[0053] For illustrative purposes, the sidewall of the mounting cavity 120 is located between the top wall and the bottom wall of the mounting cavity 120 and can connect the top wall and the bottom wall of the mounting cavity 120, which will not be elaborated further here.

[0054] In one embodiment, the guide portion is provided with a guide protrusion extending along the axial direction of the mounting through hole 110, and the damper 500 is provided with a guide groove at one end away from the limiting portion 213, the guide groove being assembled with the guide protrusion.

[0055] The guide protrusion is located in the guide groove and can reciprocate along the extension direction of the guide groove, thereby driving the damper 500 to move along the axial direction of the mounting through hole 110.

[0056] As an alternative embodiment to the above embodiment, the guide portion is provided with a guide groove extending along the axial direction of the mounting through hole 110, and the end of the damper 500 away from the limiting portion 213 is provided with a guide protrusion, which is assembled with the guide groove. Similar to the above embodiment, it will not be described again here.

[0057] In other embodiments, the guiding engagement between the guide portion and the damper 500 can also be achieved by other guiding engagement methods such as guide rails and rollers, or slide rails or sliders, which are not specifically limited here.

[0058] Please see Figure 1 In one embodiment, at least two dampers 500 are provided, and all dampers 500 are arranged at circumferential intervals along the limiting portion 213. At least two guide portions are provided and are arranged in one-to-one correspondence with the dampers 500.

[0059] At least two dampers 500 are arranged circumferentially at intervals along the limiting portion 213, so that the regulating mechanism 200 can be buffered in at least two different directions, thereby improving the buffering effect on the regulating mechanism 200 and the power quality monitoring terminal.

[0060] Please see Figure 1 In one embodiment, the adjustment mechanism 200 further includes a screw 220. The adjustment seat 210 has a screw hole, the axis of which is parallel to the axis of the mounting through hole 110. The screw 220 is threadedly engaged with the screw hole. One end of the screw 220 abuts against the side wall of the mounting cavity 120 opposite to the mounting through hole 110, and the other end of the screw 220 protrudes from the outer wall of the adjustment seat 210.

[0061] The operator can rotate the screw 220 by rotating the end of the screw 220 that protrudes from the outer wall of the adjusting seat 210, causing the screw 220 to move along the axial direction of the screw hole. One end of the screw 220 abuts against the bottom wall of the mounting cavity 120. Thus, when the relative position of the screw 220 and the adjusting seat 210 changes, the adjusting seat 210 can move along the axial direction of the mounting through hole 110. This design is simple in structure and has low implementation cost.

[0062] Please see Figure 1 In one embodiment, the screw 220 passes through the screw hole and is threaded into the screw hole. One end of the screw 220 is rotatably connected to the bottom wall of the mounting cavity 120, and the other end of the screw 220 is provided with a nut 221 so that the operator can rotate the screw 220 by rotating the nut 221, thereby driving the adjusting seat 210 to move along the axial direction of the mounting through hole 110.

[0063] For illustrative purposes, the end of the screw 220 away from the nut 221 may not be connected to the bottom wall of the mounting cavity 120, or it may be rotatably connected to the bottom wall of the mounting cavity 120. When the end of the screw 220 away from the nut 221 is not connected to the bottom wall of the mounting cavity 120 but only abuts against the bottom wall of the mounting cavity 120, rotating the screw 220 can only drive the adjusting seat 210 to move along the mounting cavity 120 toward the mounting through hole 110. When it is necessary to move the adjusting seat 210 along the mounting through hole 110 toward the mounting cavity 120, the adjusting seat 210 needs to be manually pushed. When the screw 220 is rotatably connected to the bottom wall of the mounting cavity 120, it is only necessary to rotate the screw 220 in different directions to drive the adjusting seat 210 to move back and forth along the axis of the mounting through hole 110.

[0064] Please see Figure 2 In one embodiment, the adjustment mechanism 200 further includes a rotating rod 230, one end of which is rotatably disposed on the adjustment seat 210, and the other end of which is connected to the positioning mechanism 300.

[0065] One end of the rotating rod 230 is rotatably mounted on the adjusting seat 210 to drive the positioning mechanism 300 at the other end of the rotating rod 230 to rotate, thereby driving the power quality monitoring terminal on the positioning mechanism 300 to rotate, so as to adjust the direction of the power quality monitoring terminal. With this setting, the direction of the power quality monitoring terminal can be adjusted without disassembling the power quality monitoring terminal, ensuring the monitoring accuracy of the power quality monitoring terminal.

[0066] Alternatively, staff can manually rotate the positioning mechanism 300 to adjust the direction of the power quality monitoring terminal, or they can set up a drive motor or other means connected to the rotating rod 230 to drive the rotating rod 230 to rotate, thereby adjusting the direction of the power quality monitoring terminal. No specific limitation is made here.

[0067] Please see Figures 2 to 3In one embodiment, the adjusting seat 210 has a communicating adjusting through hole and an adjusting cavity 214. The adjusting through hole is located on the second side 212. The end of the rotating rod 230 away from the positioning mechanism 300 passes through the adjusting through hole and is rotatably connected to the bottom wall of the adjusting cavity 214. The adjusting mechanism 200 also includes a locking gear 240, a locking rod 250, and a first elastic member 260. The locking gear 240 is sleeved outside the rotating rod 230 and located inside the adjusting cavity 214. The locking rod 250 has... The first end 251 and the second end 252 are opposite to each other. The first end 251 is rotatably disposed on the cavity wall of the adjustment cavity 214, and the second end 252 is used to engage with the meshing teeth of the engagement gear 240. One end of the first elastic member 260 is disposed on the cavity wall of the adjustment cavity 214, and the other end of the first elastic member 260 is connected to the side wall of the engagement rod 250. The first elastic member 260 is used to apply a pulling force to the engagement rod 250 so that the second end 252 has a tendency to move toward the engagement gear 240.

[0068] The adjustment cavity 214 is used to accommodate the locking gear 240, the locking rod 250, and the first elastic element 260. Under the action of the first elastic element 260, the second end 252 of the locking rod 250 tends to move towards the locking gear 240, so that the second end 252 of the locking rod 250 engages with the meshing teeth of the locking gear 240 to prevent the rotating rod 230 from rotating and causing the power quality monitoring terminal on the adjustment seat 210 to rotate, so that the power quality monitoring terminal can maintain its current angle. When it is necessary to adjust the angle of the power quality monitoring terminal, the locking rod 250 is moved, so that the second end 252 of the locking rod 250 moves away from the locking gear 240, thereby causing the second end 252 to disengage from the meshing teeth of the locking gear 240. At this time, the rotating rod 230 can rotate, so that the operator can rotate the adjustment seat 210 to adjust the angle of the power quality monitoring terminal on the adjustment seat 210.

[0069] To explain, without applying any external force, the locking rod 250 is only subjected to the tension of the first elastic element 260, so that the end of the locking rod 250 away from the locking seat can be locked between any two adjacent meshing teeth of the locking gear 240. Under the meshing action of the locking rod 250 and the locking gear 240, the rotating rod 230 will not easily rotate.

[0070] In one embodiment, the adjustment mechanism 200 further includes a hinge seat 270, which is disposed on the cavity wall of the adjustment cavity 214, and one end of the locking rod 250 is rotatably disposed on the hinge seat 270.

[0071] Furthermore, the hinge seat 270 is provided with a hinge rod, which passes through the side wall of the snap-fit ​​rod 250 so that the snap-fit ​​rod 250 can be rotatably mounted on the hinge seat 270.

[0072] Optionally, the first elastic element 260 can be a spring or a rubber rope or other elastic component; no specific limitation is made here.

[0073] Please see Figures 2 to 3 In one embodiment, the adjustment mechanism 200 further includes a toggle member 280, which is disposed on the side wall of the latching rod 250. A toggle through hole 215 is provided on the second side 212, which communicates with the adjustment cavity 214. The toggle member 280 passes through the toggle through hole 215.

[0074] With this configuration, the operator can move the actuating member 280 through the actuating through hole 215 on the second side 212, thereby causing the second end 252 of the locking rod 250 to move away from the locking gear 240.

[0075] Furthermore, the actuating through hole 215 is a strip-shaped hole, and the radial direction of the strip-shaped actuating through hole 215 matches the moving direction of the second end 252 of the snap-fit ​​rod 250.

[0076] In other embodiments, the actuating through hole 215 may also be a through hole with a large opening area to ensure that the actuating member 280 can move within the actuating through hole 215.

[0077] Please see Figure 4 In one embodiment, the positioning mechanism 300 further includes a positioning seat 310, a connector 320, a first clamping member 330, a second clamping member 340, a second elastic member 350, and a third elastic member 360. The positioning seat 310 is disposed on the second side 212, the connector 320 is disposed on the positioning seat 310, and the first clamping member 330 and the second clamping member 340 are movably disposed on the positioning seat 310. The first clamping member 330 and the second clamping member 340 are respectively located on opposite sides of the connector 320. One end of the second elastic member 350 is connected to the connector 320, and the other end of the second elastic member 350 is connected to the first clamping member 330. One end of the third elastic member 360 is connected to the connector 320, and the other end of the third elastic member 360 is connected to the second clamping member 340.

[0078] When the power quality monitoring terminal needs to be installed on the positioning mechanism 300, the first clamping member 330 and the second clamping member 340 are first moved away from the connecting member 320. Then, the power quality monitoring terminal is placed between the first clamping member 330 and the second clamping member 340. Under the action of the second elastic member 350 and the third elastic member 360, both the first clamping member 330 and the second clamping member 340 tend to move towards the connecting member 320 to clamp the power quality monitoring terminal, thereby realizing the installation of the power quality monitoring terminal. This setting not only facilitates the installation and removal of the power quality monitoring terminal, but also provides a more reliable installation effect for the power quality monitoring terminal.

[0079] Further, please refer to Figure 4 The first clamping member 330 is provided with a first limiting protrusion 331, and the second clamping member 340 is provided with a second limiting protrusion 341. The first limiting protrusion 331 and the second limiting protrusion 341 are arranged opposite to each other. The outer wall of the power quality monitoring terminal is provided with a first limiting groove and a second limiting groove. When the first clamping member 330 and the second clamping member 340 approach each other and clamp the power quality monitoring terminal, the first limiting protrusion 331 is assembled with the first limiting groove, and the second limiting protrusion 341 is assembled with the second limiting groove, thereby further improving the installation reliability of the power quality monitoring terminal.

[0080] In one embodiment, the connector 320 is provided with a first limiting guide rail and a second limiting guide rail on opposite sides, and the first clamping member 330 and the second clamping member 340 are movably disposed on the first limiting guide rail and the second limiting guide rail, respectively. Under the action of the first limiting guide rail and the second limiting guide rail, the movement reliability of the first clamping member 330 and the second clamping member 340 is improved.

[0081] Optionally, the second elastic element 350 and the third elastic element 360 can be springs or elastic components such as rubber ropes, without specific limitations here.

[0082] Please see Figure 2 In one embodiment, the positioning seat 310 has a relief groove 311 on the side facing the adjustment seat 210, and the actuating through hole 215 is opened in the relief groove 311. In this way, the operator can move the actuating member 280 passing through the actuating through hole 215 through the relief groove 311, thereby driving the second end 252 of the locking rod 250 to move away from the locking gear 240.

[0083] Furthermore, staff can hold a rod-shaped object such as a screwdriver and enter the clearance groove 311 to move the actuating component 280, which will not be described in detail here.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
