Description

Technical Field

[0001] This utility model relates to the field of building electrical equipment installation and layout technology, and in particular to a building electrical sound insulation and vibration reduction device. Background Technology

[0002] Building electrical systems refer to the electrical platform constructed within a building using scientific theories and electrical technology, encompassing both high-voltage (e.g., power supply, lighting, lightning protection) and low-voltage (e.g., telephone, television, fire protection, and building automation) systems. In building electrical design, to improve the acoustic performance of the indoor or working environment and reduce noise transmission, soundproof enclosures are often used to enclose electrical equipment. However, existing soundproof enclosures are simply rectangular front-opening boxes with a basic structure. While they offer some sound insulation, they are still susceptible to malfunction or damage from external vibrations, especially for electrical equipment containing numerous precision components. Furthermore, the excessively sealed interior of existing soundproof enclosures leads to poor heat dissipation, causing electrical equipment to shut down or even break down during prolonged operation due to insufficient heat dissipation. Summary of the Invention

[0003] The purpose of this utility model is to provide a building electrical sound insulation and vibration reduction device to address the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution: The building electrical sound insulation and vibration reduction device of this utility model includes a box with a front door, and a rectangular bearing cavity inside the box. A damping telescopic rod that can extend and retract vertically is vertically arranged on the bottom wall of the bearing cavity. The upper end of the damping telescopic rod is fixedly connected to a horizontal platform for supporting electrical equipment. A flexible fixing sleeve that is snapped onto the top wall of the electrical equipment is arranged in the bearing cavity above the horizontal platform. The left and right sides of the flexible fixing sleeve are fixedly connected to the side wall of the bearing cavity by horizontally arranged tension springs. A plurality of support springs for pushing the horizontal platform upward are arranged in the bearing cavity below the horizontal platform. The lower end of the support spring is hinged to the bottom wall of the bearing cavity by a rotating rod, and its upper end abuts against the bottom wall of the horizontal platform. A positioning guide rod that is vertically arranged on the bottom wall of the horizontal platform and inserted into the support spring is correspondingly arranged in one by one.

[0005] Furthermore, the horizontal platform is a rectangular plate. In this case, the supporting springs and the positioning guide rods are four sets that correspond one-to-one and are evenly distributed at the four corners of the horizontal platform. At the same time, the upper end of the damping telescopic rod should be fixed to the center of the bottom surface of the horizontal platform.

[0006] Furthermore, to improve the sound insulation of the enclosure, a layer of sound-insulating cotton can be sandwiched inside the enclosure wall to form a sandwich structure, which effectively reduces noise.

[0007] Furthermore, the flexible fixing sleeve is a rubber or silicone sleeve with an opening facing downwards that is adapted to snap onto the top wall of the electrical equipment, thereby securing it firmly onto the electrical equipment and using the tension springs on both sides to form a lateral shock absorption and protection effect on the electrical equipment.

[0008] Furthermore, in order to efficiently dissipate heat from the electrical equipment inside the enclosure, at least one set of heat dissipation vents can be opened on the horizontal platform. A vertically downward blowing electric fan is connected to the heat dissipation vent through a horizontal cantilever. An exhaust vent is opened on the bottom wall of the enclosure directly below the heat dissipation vent, and a dustproof net is covered on the exhaust vent to ensure that the exhaust hot air dissipates heat while reducing the entry of dust and debris into the enclosure.

[0009] The advantages of this invention lie in its use of a horizontal platform connected by damping telescopic rods to support the electrical equipment. Simultaneously, four sets of vertically arranged support springs evenly distributed at the four corners of the horizontal platform, and a pair of horizontally arranged tension springs connected to the left and right sides of the flexible fixing sleeve, achieve lateral and longitudinal vibration damping protection for the electrical equipment. This reduces vibrations caused by various environmental factors and weakens the self-vibration generated by spring buffering, achieving excellent vibration damping effects. Furthermore, the heat dissipation vents on the horizontal platform, the exhaust vents on the bottom wall of the enclosure, and the electric fan installed within the heat dissipation vents accelerate the heat dissipation of the electrical equipment, preventing it from operating at high temperatures for extended periods and avoiding shutdowns or even damage.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0014] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium; unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1 , 2 As shown, the building electrical sound insulation and vibration reduction device of this utility model includes a rectangular box 1, which has a rectangular bearing cavity 2 for installing electrical equipment 100 inside. The front wall of the box 1 is a front door 3 hinged thereon. In addition, in order to improve the sound insulation effect of the box 1, a sound insulation cotton layer 4 can be sandwiched inside the box wall of the box 1 to form a sandwich structure box wall, which effectively reduces noise.

[0016] A damping telescopic rod 5 that extends vertically is vertically installed at the center of the bottom wall of the bearing cavity 2. The upper end of the damping telescopic rod 5 is the telescopic end, and a horizontal platform 6 for supporting the electrical equipment 100 is fixedly connected to it.

[0017] A flexible fixing sleeve 7 is provided in the bearing cavity 2 located above the horizontal platform 6 for fastening onto the top wall of the electrical equipment 100. The flexible fixing sleeve 7 is a rubber or silicone sleeve with an opening facing downwards, which is elastic and can be securely fastened onto the electrical equipment 100. The left and right sides of the flexible fixing sleeve 7 are fixed to the side walls of the bearing cavity 2 by horizontally arranged tension springs 8, thereby using the tension springs 8 on both sides and the flexible fixing sleeve 7 to form a lateral shock absorption and protection effect for the electrical equipment 100.

[0018] Multiple support springs 9 are installed in the bearing cavity 2 located below the horizontal platform 6 to push the horizontal platform 6 upward. The lower end of the support spring 9 is hinged to the bottom wall of the bearing cavity 2 through the rotating rod 10, while the upper end is abutted against the bottom wall of the horizontal platform 6. In addition, a positioning guide rod 11 is vertically installed on the bottom wall of the horizontal platform 6, which is inserted into the support spring 9.

[0019] Preferably, the horizontal platform 6 is a rectangular plate. In this case, the support springs 9 and the positioning guide rods 11 are in four sets, evenly distributed at the four corners of the horizontal platform 6. At the same time, the upper end of the damping telescopic rod 5 should be fixed to the center of the bottom surface of the horizontal platform 6. Thus, under the action of the four sets of support springs 9 and positioning guide rods 11, the horizontal platform 6 can achieve the purpose of longitudinal shock absorption and protection. Under the action of the damping telescopic rod 5, the horizontal platform 6 can be raised and lowered smoothly, weakening the self-vibration generated by the buffering of the support springs 9, and achieving excellent shock absorption effect.

[0020] Furthermore, to efficiently dissipate heat from the electrical equipment 100 inside the enclosure 1, at least one set of heat dissipation vents 12 can be opened on the horizontal platform 6. A vertically downward-blowing electric fan 14 is connected to each heat dissipation vent 12 via a horizontal cantilever 13. An exhaust vent 15 is opened on the bottom wall of the enclosure 1 directly below the heat dissipation vents 12, allowing the electric fan 14 to directly blow hot air out through the exhaust vent 15, accelerating the heat dissipation of the electrical equipment 100 and achieving the heat dissipation purpose. In addition, a dustproof net 16 should be installed over the exhaust vent 15 for dust prevention. For easy cleaning, the dustproof net 16 is detachably installed on the exhaust vent 15, ensuring not only the dissipation of hot air from the exhaust vent 15 but also reducing the entry of dust and debris into the enclosure 1.

[0021] During actual installation, first press down on the support spring 9 to disengage it from the positioning guide rod 11, and rotate the support spring 9 by a certain angle so that the upper end of the support spring 9 no longer supports the bottom wall of the horizontal platform 6. Then, you can easily press down on the horizontal platform 6, place the electrical equipment 100 on the horizontal platform 6, and fit the flexible fixing sleeve 7 onto the electrical equipment 100 to form lateral shock absorption protection for the electrical equipment 100. After that, press down on the support spring 9 again and rotate it so that the upper end of the support spring 9 is once again fitted onto the positioning guide rod 11. At this time, releasing the support spring 9 will cause it to automatically spring back and support the bottom wall of the horizontal platform 6, thereby forming longitudinal shock absorption protection for the electrical equipment 100, and completing the installation of the electrical equipment 100.

[0022] When it is necessary to cool down the electrical equipment 100, the electric fan 14 can be controlled to work, and hot air can be blown out through the exhaust port 15 to achieve the purpose of heat dissipation, prevent the electrical equipment 100 from working in a high-temperature state for a long time, and avoid the electrical equipment 100 from shutting down or even being damaged.
