Description

Technical Field

[0001] This utility model relates to the field of capacitor installation technology, specifically a compact capacitor that is easy to install on site. Background Technology

[0002] A capacitor is a component that stores electrical charge and energy. A system of conductors, where one conductor is surrounded by another, or where all the electric field lines emanating from one conductor terminate in another, is called a capacitor. In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a component that can store charge and is one of the most commonly used electronic components. However, in an AC circuit, because the direction of the current changes with time, and the charging and discharging process of a capacitor takes time, a changing electric field is formed between the plates. This electric field also changes with time. In fact, the current passes through the capacitor in the form of an electric field. Capacitors are widely used in various electrical equipment. Currently, some large-volume capacitors are usually bolted into a casing and transported to the site. Because of their large size after installation, they occupy a lot of space and are inconvenient to transport. Furthermore, the installation process relies on screws for fixation, and if a fault occurs, many bolts need to be removed, making maintenance inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a compact capacitor that is easy to install on-site, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compact capacitor that is easy to install on site, including a mounting frame, a fixing component, and a shock-absorbing component;

[0005] Wherein: the bottom of the mounting frame is provided with a mounting base, and the top of the mounting frame is provided with a capacitor;

[0006] The fixing assembly includes a bidirectional lead screw rotatably mounted inside a mounting frame. Slider blocks are threaded to both ends of the bidirectional lead screw. A fixing clamp is fixedly mounted on the top of each slider. A groove is formed on the surface of the mounting frame. The fixing clamp is inserted into the groove and fixedly clamps the capacitor. A rocker wheel is rotatably mounted on one end of the mounting frame. A drive gear is fixedly mounted on the surface of the rocker wheel. A driven gear is fixedly mounted on one end of the bidirectional lead screw. The drive gear and the driven gear mesh with each other.

[0007] The shock absorption assembly includes a fixed sleeve installed around the inside of the mounting base. A shock absorption spring is installed inside the fixed sleeve. A movable column is installed inside the fixed sleeve. A fixed plate is installed on the top of the movable column. The fixed plate is installed at the bottom of the mounting frame. The shock absorption spring is sleeved on the surface of the movable column and one end contacts the bottom of the fixed plate.

[0008] As a preferred embodiment of this utility model: a protective cover is installed on the top of the mounting frame, and ventilation holes are provided on both sides of the protective cover.

[0009] As a preferred embodiment of this utility model: a slide rail is fixedly installed on the inner wall of the mounting frame, and a limit block is installed at the bottom of the slider, and the limit block is slidably installed on the surface of the slide rail.

[0010] As a preferred embodiment of this utility model: a plurality of positioning posts are installed on the bottom edge of the fixing plate, the positioning posts are slidably inserted into the top edge of the fixing sleeve, and the bottom end of the positioning posts is connected to an anti-detachment block.

[0011] As a preferred embodiment of this utility model, the surface of the protective cover is provided with wiring holes.

[0012] As a preferred embodiment of this utility model, the back of the fixing clamp is equipped with reinforcing ribs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) A bidirectional lead screw is rotatably installed inside the mounting frame. When the rocker wheel is rocked, the driving gear is driven to rotate. The driving gear drives the bidirectional lead screw to rotate inside the mounting frame through the driven gear. The rotation of the bidirectional lead screw causes the sliders connected by threads at both ends to rotate accordingly. Since the bottom of the slider is equipped with a limit block, the limit block slides on the slide rail surface installed on the inner wall of the mounting frame. After the bidirectional lead screw rotates, the sliders at both ends move closer or further away from each other along the bidirectional lead screw. The sliding of the slider drives the top fixing plate to move in the slide groove, thereby clamping and fixing the capacitor placed on the top of the mounting frame, replacing the bolt installation method. This makes it easier to combine and fix the capacitor and the mounting frame on site, and facilitates subsequent maintenance.

[0015] (2) With the provided shock absorption components, a fixed sleeve is installed around the inside of the mounting base. A shock absorption spring is installed inside the fixed sleeve. The movable column is inserted inside the fixed sleeve and compresses the shock absorption spring. When the mounting frame vibrates, it drives the movable column to move into the fixed sleeve. The movable column applies pressure to the shock absorption spring. The shock absorption spring dissipates the vibration transmitted by the mounting frame through its own elastic deformation, so that the capacitor can be stably installed on the top of the mounting frame.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-4 A compact capacitor that is easy to install in the field includes: a mounting frame 1, a fixing component 4, and a shock-absorbing component 5; the bottom of the mounting frame 1 is provided with a mounting base 2, and the top of the mounting frame 1 is equipped with a capacitor 3.

[0023] Please see Figure 1 , Figure 3 The fixing component 4 includes a bidirectional lead screw 41 rotatably installed inside the mounting frame 1. The two ends of the bidirectional lead screw 41 are threadedly connected to sliders 42. A fixing clamp 43 is fixedly installed on the top of the slider 42. A groove 44 is opened on the surface of the mounting frame 1. The fixing clamp 43 is inserted into the groove 44 and fixedly clamped to the capacitor 3. A rocker wheel 45 is rotatably installed on one end of the mounting frame 1. A drive gear 46 is fixedly installed on the surface of the rocker wheel 45. A driven gear 47 is fixedly installed on one end of the bidirectional lead screw 41. The drive gear 46 and the driven gear 47 are meshed and connected. A slide rail 8 is fixedly installed on the inner wall of the mounting frame 1. A limit block 9 is installed on the bottom of the slider 42. The limit block 9 is slidably installed on the surface of the slide rail 8.

[0024] In practical use: A bidirectional lead screw 41 is rotatably installed inside the mounting frame 1. When the rocker wheel 45 is rocked, it drives the drive gear 46 to rotate. The drive gear 46 drives the bidirectional lead screw 41 to rotate inside the mounting frame 1 through the driven gear 47. The rotation of the bidirectional lead screw 41 causes the sliders 42 connected by threads at both ends to rotate accordingly. Since the bottom of the slider 42 is equipped with a limit block 9, the limit block 9 slides on the surface of the slide rail 8 installed on the inner wall of the mounting frame 1. After the bidirectional lead screw 41 rotates, the sliders 42 at both ends move closer or further away from each other along the bidirectional lead screw 41. The sliding of the slider 42 drives the top fixing plate 43 to move in the slide groove 44, thereby clamping and fixing the capacitor 3 placed on the top of the mounting frame 1, replacing the bolt installation method. This makes it easier to combine and fix the capacitor 3 and the mounting frame 1 on site, and facilitates subsequent maintenance.

[0025] Please see Figure 2 , Figure 4 The shock absorption assembly 5 includes a fixed sleeve 51 installed around the inside of the mounting base 2. A shock absorption spring 52 is installed inside the fixed sleeve 51. A movable column 53 is installed inside the fixed sleeve 51. A fixed plate 54 is installed on the top of the movable column 53. The fixed plate 54 is installed at the bottom of the mounting frame 1. The shock absorption spring 52 is sleeved on the surface of the movable column 53 and one end is in contact with the bottom of the fixed plate 54.

[0026] In practical use: a fixed sleeve 51 is installed around the inside of the mounting base 2. A shock-absorbing spring 52 is installed inside the fixed sleeve 51. The movable column 53 is inserted inside the fixed sleeve 51 and compresses the shock-absorbing spring 52. When the mounting frame 1 vibrates, the movable column 53 is driven to move into the fixed sleeve 51 through the fixed plate 54. The movable column 53 applies pressure to the shock-absorbing spring 52. The shock-absorbing spring 52 dissipates the vibration transmitted by the mounting frame 1 through its own elastic deformation, so that the capacitor 3 can be stably installed on the top of the mounting frame 1.

[0027] Please see Figure 1 , Figure 2 A protective cover 6 is installed on the top of the mounting frame 1, and ventilation holes 7 are opened on both sides of the protective cover 6.

[0028] In practical use: The top of the mounting frame 1 is equipped with a protective cover 6. After the capacitor 3 is installed, it is covered by the protective cover 6, which serves to prevent water and dust. The ventilation holes 7 on both sides of the protective cover 6 facilitate airflow to carry away the heat generated by the capacitor 3, thus achieving a cooling effect.

[0029] Please see Figure 4 Multiple positioning posts 10 are installed on the bottom edge of the fixing plate 54. The positioning posts 10 slide through the top edge of the fixing sleeve 51. The bottom end of the positioning post 10 is connected to an anti-detachment block 11.

[0030] In practical use: a positioning post 10 is installed on the bottom edge of the fixed plate 54. The positioning post 10 slides through the top edge of the fixed sleeve 51. When the movable post 53 moves into the fixed sleeve 51, the positioning post 10 slides up and down on the top of the fixed sleeve 51, so that the movable post 53 keeps moving up and down in a straight line. The anti-detachment block 11 at the bottom of the positioning post 10 prevents the positioning post 10 from detaching from the top of the fixed sleeve 51.

[0031] Please see Figure 2 The protective cover 6 has wiring holes 12 on its surface.

[0032] In practical use: The wiring hole 12 on the surface of the protective cover 6 facilitates the connection of external wiring to the capacitor 3.

[0033] Please see Figure 3 The back of the fixing plate 43 is equipped with reinforcing ribs 13.

[0034] In practical use: the fixing plate 43 is reinforced by the reinforcing ribs 13 installed on the back to enhance the structural strength and prevent the fixing plate 43 from deforming or being damaged.

[0035] A bidirectional lead screw 41 is rotatably installed inside the mounting frame 1. When the rocker wheel 45 is rocked, it drives the drive gear 46 to rotate. The drive gear 46 drives the bidirectional lead screw 41 to rotate inside the mounting frame 1 through the driven gear 47. The rotation of the bidirectional lead screw 41 causes the sliders 42 connected by threads at both ends to rotate accordingly. Since the bottom of the slider 42 is equipped with a limit block 9, the limit block 9 slides on the surface of the slide rail 8 installed on the inner wall of the mounting frame 1. After the bidirectional lead screw 41 rotates, the sliders 42 at both ends move closer or further away from each other along the bidirectional lead screw 41. The sliding of the slider 42 drives the top fixing plate 43 to move in the slide groove 44, thereby clamping and fixing the capacitor 3 placed on the top of the mounting frame 1, replacing the bolt installation method. This makes it easier to combine and fix the capacitor 3 and the mounting frame 1 on site, and facilitates subsequent maintenance.
