Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a power line carrier concentrator. Background Technology

[0002] Power line carrier concentrators are the core equipment in power line carrier communication systems. They serve as the link between the master station and the electricity meter and are the central component of the entire system design. They play an important role in power systems and are widely used in IoT and smart home scenarios.

[0003] Most existing power line carrier concentrators lack external protective casings, making them susceptible to damage from external factors. While some concentrators have protective casings, the dust filters on these casings tend to accumulate dust over time, requiring removal for cleaning and maintenance. This significantly increases the workload for maintenance personnel. Therefore, designing a power line carrier concentrator is a necessary step to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power line carrier concentrator. To address usability issues, it incorporates a housing and a limiting mechanism. By controlling the two clamping plates to move in opposite directions, the concentrator body can be confined within the housing, ensuring safe operation. It also features a heat dissipation and dustproof mechanism for air cooling. Furthermore, by alternating the use of fans and a brush, the dustproof mesh can be easily cleaned, ensuring effective heat dissipation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power line carrier concentrator includes a concentrator body and a housing, the concentrator body being located inside the housing; a limiting mechanism, the limiting mechanism including a support plate fixedly connected inside the housing, the upper end of the support plate having a positioning groove vertically formed, the upper end of the support plate having a rectangular through groove vertically formed, a bidirectional threaded rod rotatably connected between the inner walls of the left and right sides of the housing, each of the two threaded ends of the bidirectional threaded rod having a first slider threadedly connected to it, the upper ends of the two first sliders passing through the rectangular through groove and fixedly connected to a clamping plate, the opposing sides of the two clamping plates being provided with rubber pads; and a heat dissipation and dust prevention mechanism, the heat dissipation and dust prevention mechanism being used to achieve heat dissipation and dust prevention for the concentrator body.

[0007] Preferably, the lower end of the concentrator body is fitted with the inner wall of the positioning groove, and both first sliders are slidably connected to the inner wall of the rectangular through groove.

[0008] Preferably, the two threaded ends of the bidirectional threaded rod have opposite thread directions, and the right end of the bidirectional threaded rod penetrates the right inner wall of the housing and is fixedly connected to a circular control block.

[0009] Preferably, the heat dissipation and dust prevention mechanism includes two cooling fans, and ventilation openings are horizontally provided on the inner walls of both the left and right sides of the housing. The two cooling fans are each located in a corresponding ventilation opening, and a dustproof net is provided in each of the two ventilation openings. The two dustproof nets are located on the outside of the corresponding cooling fans.

[0010] Preferably, two fixing blocks are fixedly connected to both the left and right sides of the housing, and a guide rod is fixedly connected between each pair of cooperating fixing blocks. A second slider is slidably connected to each of the two guide rods, and a brush is provided on the opposing side of each of the two second sliders. Each brush is cooperating with a corresponding dustproof net.

[0011] Preferably, a sliding door is provided on the front side of the housing, and a mounting plate is fixedly connected to the rear side of the housing.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] The device is equipped with a housing and a limiting mechanism. By rotating the circular control block, the bidirectional threaded rod rotates, causing the two clamping plates to move towards each other. This conveniently and stably limits the concentrator body within the housing, preventing damage from external factors. A heat dissipation and dustproof mechanism is also included. Two fans, in conjunction with two dust filters, provide air cooling for the concentrator body.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A power line carrier concentrator includes a concentrator body 1 and a housing 2. The concentrator body 1 is located inside the housing 2. A sliding door 17 is provided on the front side of the housing 2. A mounting plate 18 is fixedly connected to the rear side of the housing 2. The mounting plate 18 has multiple mounting holes, which can facilitate the subsequent fixing of the entire device to a designated position.

[0021] The device also includes a limiting mechanism, which includes a support plate 3 fixedly connected inside the housing 2. The upper end of the support plate 3 is vertically provided with a positioning groove 4, which can realize the pre-positioning of the concentrator body 1 before limiting it. The lower part of the concentrator body 1 is in contact with the inner wall of the positioning groove 4. The upper end of the support plate 3 is vertically provided with a rectangular through groove 5. A bidirectional threaded rod 6 is rotatably connected between the inner walls of the left and right sides of the housing 2. The two threaded ends of the bidirectional threaded rod 6 have opposite thread directions. A first slider 7 is threadedly connected to each of the two threaded ends of the bidirectional threaded rod 6. The upper ends of the two first sliders 7 pass through the rectangular through groove 5 and are fixedly connected with clamping plates 8. The two first sliders 7 are slidably connected to the inner wall of the rectangular through groove 5. Rubber pads 9 are provided on the opposite sides of the two clamping plates 8. The right end of the bidirectional threaded rod 6 passes through the right inner wall of the housing 2 and is fixedly connected with a circular control block 10.

[0022] The system also includes a heat dissipation and dust prevention mechanism, which is used to dissipate heat and prevent dust from entering the concentrator body 1. The heat dissipation and dust prevention mechanism includes two cooling fans 11, both of which are unidirectional and have strong airflow. The cooling fan 11 on the left blows to the left and the cooling fan 11 on the right blows to the right. Ventilation openings are horizontally provided on the inner walls of both sides of the housing 2. The two cooling fans 11 are located in the corresponding ventilation openings. Dustproof nets 12 are provided in both ventilation openings. The two dustproof nets 12 are located on the outside of the corresponding cooling fans 11, which can effectively prevent dust from entering the housing 2. Two fixing blocks 13 are fixedly connected to both sides of the housing 2. A guide rod 14 is fixedly connected between each pair of mating fixing blocks 13. A second slider 15 is slidably connected to each of the two guide rods 14. Brushes 16 are provided on the opposing sides of the two second sliders 15. The two brushes 16 cooperate with the corresponding dustproof nets 12 to brush up the dust adhering to the dustproof nets 12.

[0023] In this utility model, when in use, first use multiple bolts to install the mounting plate 18 to the designated position, place the lower part of the concentrator body 1 into the positioning groove 4 to ensure the pre-positioning before limiting it, then rotate the circular control block 10 to drive the bidirectional threaded rod 6 to rotate, which drives the two first sliders 7 and the two clamping plates 8 to move synchronously towards each other until the rubber pads 9 on the two clamping plates 8 respectively clamp the left and right sides of the concentrator body 1, thus conveniently achieving stable limiting of the concentrator body 1;

[0024] After installation, one of the cooling fans 11 can be turned on (taking the left cooling fan 11 as an example). This allows outside air to flow along the path from the right-side vent of housing 2 to the inside of housing 2 and then to the left-side vent. The leftward airflow cools the concentrator body 1, ensuring its stable operation. After a period of continuous cooling, the right-side vent, being the air intake, will accumulate dust on the right side of the dust filter 12. At this point, the operator can turn off the left cooling fan 11 and turn on the right cooling fan 11. Outside air flows along the path from the vent on the left side of housing 2 to the inside of housing 2 and then to the vent on the right side of housing 2. During this process, the air flowing to the right continues to maintain the air cooling of the concentrator body 1. At the same time, the operator can move the second slider 15 on the right side up and down, which drives the corresponding brush 16 to brush the dust screen 12 on the right side. With the rightward airflow, the dust adhering to the dust screen 12 can be brushed up and blown away. This makes it easy to clean the dust screen 12 and ensures the heat dissipation effect of the concentrator body 1. Similarly, the dust screen 12 on the left side can also be cleaned by referring to the above operation.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
