[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0035] This embodiment provides an installation system for a communication device of an electric power device, including a guide rail 1 and a communication device, wherein the communication device is fixedly installed on the guide rail 1, wherein the communication device is used for inverter working information collection and energy dispatch management.
[0036] Reference Figures 1 to 7 As shown, the communication device has a mounting seat 2, which is specifically a base or shell of the communication device. The mounting seat 2 has a mounting slot 12 for inserting the guide rail 1 and a receiving slot 24 for receiving the clamping mechanism 3, and the clamping mechanism 3 is located in the receiving slot 24 and can move relative to the receiving slot 24.
[0037] Furthermore, there are multiple clamping mechanisms 23, and the clamping mechanisms 23 are used to fix the mounting seat 2 of the communication device on the guide rail 1. In this embodiment, an abutting mechanism 21 for clamping the guide rail 1 is pre-set on the mounting seat 2. After the mounting seat 2 is installed on the guide rail 1 at a certain inclination angle, the abutting mechanism 21 clamps one side of the guide rail 1, and then two clamping mechanisms 23 are set on the other side of the guide rail 1. The clamping mechanism 23 and the abutting mechanism 21 of the mounting seat 2 cooperate to fix the mounting seat 2 on the guide rail 1. In other embodiments, a plurality of clamping assembly clamping mechanisms 23 can be set on one side of the guide rail 1, and a plurality of clamping mechanisms 23 can be set on the other side of the guide rail 2 to fix the mounting seat 2 on the guide rail 1. The clamping mechanisms 23 are all set on the long side of the guide rail 1.
[0038] Furthermore, refer to Figures 4 to 7 As shown, the clamping mechanism 3 includes a clamping member 32 movably arranged on the mounting seat 2 and a locking member 31 capable of locking or releasing the clamping member 32. The material of the clamping member 32 is plastic, and the material of the locking member 31 is metal or plastic. The clamping member 32 has an abutting end 322 for abutting against the guide rail 1 to fix it in the mounting groove 23. After the communication device is installed on the guide rail 1, the locking member 31 locks the clamping member 32 and the mounting seat 2. Further, the clamping member 32 has a slot 321 and a positioning slot 325. The positioning slot 325 is connected to the slot 321, and the locking member 31 is inserted into the slot 321. The locking member 31 has a cam 311, and the cam 311 has a portion 313 with a smaller outer diameter.
[0039] The clamping mechanism 3 has a first state and a second state. In the first state, the clamping member 32 is movably arranged on the mounting seat 2 of the communication device, and the smaller outer diameter portion 313 of the cam 311 is inserted into the positioning groove 325 to release the clamping member 32. At this time, the length direction of the locking member 31 is the same as the length direction of the clamping member 32. In the second state, the clamping member 32 is elastically deformed and tightly contacts the mounting seat 2, and the abutting end portion 322 abuts on the guide rail 1. The smaller outer diameter portion 313 of the protrusion 311 and the inner wall of the slot 321 are tightly contacted to lock the clamping member 32. When the first state is converted to the second state, the locking member 31 rotates relative to the clamping member 32, specifically 90°. When the locking member 31 rotates 90 degrees, the cam 311 and the inner wall of the slot 321 are in close contact, and the two sides of the positioning slot 325 are forced to expand outward. The clamping member 32 is elastically deformed under the force and is in close contact with the inner wall of the accommodating slot 24. The abutting end 322 also abuts on the guide rail 1, and the mounting base 2 of the communication device is fixed on the guide rail 1.
[0040] Reference Figure 4 As shown, the clamping member 32 has a contact surface 323 that abuts against the receiving groove 24, and the contact surface 323 has a plurality of protrusions, which are triangular prism-shaped and serrated, increasing the friction between the clamping member 32 and the mounting seat 2, making the connection between the clamping member 32 and the mounting seat 2 more stable and reliable. In other embodiments, a plurality of protrusions can also be provided on the inner wall of the receiving groove 24 to obtain a greater friction. The locking member 31 includes an operating handle 312 and a rotating shaft 314, and a cam 311 is located between the operating handle 312 and the rotating shaft 314. When the first state is converted to the second state, the operating handle 312 rotates around the rotating shaft 314. The operating handle 312 has a plurality of protrusions 315, which can increase the friction and facilitate operation.
[0041] The clamping mechanism 3 further includes a connecting member 4 connecting the locking member 31 and the clamping member 32, and a first stopper 326. The connecting member 4 passes through the slot 321 and is connected to the rotating shaft 314. The connecting member 4 is specifically a screw, and an internal thread is provided in the rotating shaft 314. The screw passes through the slot 321 and is fixedly connected to the rotating shaft 314, so that the locking member 31 will not fall off the clamping member 32 easily, and will not affect the rotation of the locking member 31 relative to the clamping member 32. Further, the screw has a head and a rod, the rod passes through the slot 321 and is fixedly connected to the rotating shaft 314, and the head falls on the first stopper 326. When the first state is converted to the second state, the head rotates relative to the first stopper 326.
[0042] A positioning column 22 is provided on the bottom wall of each mounting groove 23. When assembling, the clamping mechanism 3 is first placed in the mounting groove 23, specifically, the positioning column 22 is inserted into the positioning groove 325 of the clamping member 32. The diameter of the positioning column 22 is smaller than the width of the positioning groove 325, and the clamping member 32 can move in the positioning groove 325. Specifically, the movement and adjustment are performed according to the width of the guide rail 1. When the width of the guide rail 1 increases, the clamping member 32 can be moved in a direction away from the guide rail 1, and when the width of the guide rail 1 decreases, the clamping member 32 can be moved in a direction close to the guide rail 1. Further, the clamping member 32 is provided with a second stopper 327 that can abut against the positioning column 22. The positioning column 22 can at least abut against a part of the second stopper 327. The second stopper 327 can effectively prevent the clamping member 32 from falling from the mounting groove 23, which is more convenient to use.
[0043] The steps of fixing the communication device of this embodiment on the guide rail are as follows: first, the clamping member 32 and the locking member 31 are connected, specifically, the rod of the screw passes through the installation groove 23 and is threadedly fixedly connected with the rotating shaft 314. The fixed connection between the screw and the rotating shaft 314 can ensure that the locking member 31 will not fall off the clamping member 32 and will not affect the rotation of the locking member 31 relative to the clamping member 32; then the clamping assembly 3 is placed in the installation groove 23, and the positioning column 22 is inserted into the positioning groove 325. Since the clamping member 32 is provided with a second stopper 323 that matches the positioning column 22, the clamping member 32 will not fall off the mounting seat 2. Finally, according to the size of the guide rail 1, the clamping member 32 is pushed forward or backward, so that the abutting end 322 of the clamping member 32 abuts on the guide rail 1, and the locking member 31 rotates 90° clockwise or counterclockwise, and the cam 311 and the inner wall of the slot 321 are in close contact. Since the clamping member 32 is made of plastic, the two sides of the clamping member 32 are squeezed and deformed, causing the side serrated structure to be clamped on the side wall of the installation groove 23, and the clamping member 32 and the installation seat 2 are locked.
[0044] The communication device of this embodiment can be applied to guide rails of various specifications, has stronger applicability and higher versatility, and solves the problem of communication products being difficult to install and incompatible on customized guide rails.
