An electrical cabinet circuit control and energy-saving optimization device

Abstract

This utility model discloses an electrical cabinet circuit control and energy-saving optimization device, belonging to the field of electrical cabinet technology. It includes a circuit breaker with positioning holes at both the top and bottom. An internal threaded tube is fixed to the inner wall of each positioning hole. An upper pressure ring is vertically slidably mounted on the top of the positioning hole, and a first spring connects the upper pressure ring to the interior of the positioning hole. Through the synergistic action of the upper pressure ring, the first spring, the L-shaped rod, the vertical groove, and the stop block within the positioning hole, the upper pressure ring moves downwards synchronously during bolt installation. When the bolt installation torque reaches a preset value, the L-shaped rod moves below the stop block, and its elasticity causes it to make a sound upon resetting, thus providing clear installation feedback. This effectively avoids the problem of wire vibration and loosening caused by insufficient torque, significantly enhancing the stability of the device installation and its operational safety.

Description

Technical Field

[0001] This utility model relates to an electrical cabinet circuit control and energy-saving optimization device, belonging to the field of electrical cabinet technology. Background Technology

[0002] Molded case circuit breakers (MCCBs) excel in branch control and energy-saving optimization in electrical cabinet applications: they support precise branch control, achieving accurate energy consumption monitoring through graded protection, dynamic load balancing (three-phase imbalance can be reduced to within 3%), and PowerTag metering technology; in terms of energy saving, they can be linked to voltage regulation and trigger reactive power compensation (power factor improved to 0.96), and connect to the energy platform to generate optimization strategies, achieving a total energy saving of 18% in industrial scenarios and improving air conditioning efficiency by 30% in commercial buildings, effectively achieving synergistic optimization of branch control and energy saving.

[0003] However, there are still obvious shortcomings in installation and use: First, the terminal bolts lack an installation torque determination mechanism, making it difficult to ensure installation stability. If the torque is insufficient (<20N·m), the wires are prone to loosening due to vibration. Second, the installation position marking is inconvenient. The screws need to be inserted into the mounting holes and rotated slightly to leave a mark before drilling the holes. This process significantly affects the installation efficiency.

[0004] To address this issue, an electrical cabinet circuit control and energy-saving optimization device was designed. Utility Model Content

[0005] The main purpose of this utility model is to provide an electrical cabinet circuit control and energy-saving optimization device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] An electrical cabinet circuit control and energy-saving optimization device includes a circuit breaker. The circuit breaker has positioning holes at its top and bottom. An internal thread is fixed on the inner wall of the positioning hole. An upper pressure ring is vertically slidably arranged at the top of the positioning hole. A first spring is connected between the upper pressure ring and the inside of the positioning hole.

[0008] An L-shaped rod is vertically fixed on one side of the upper pressure ring, and a vertical groove adapted to the L-shaped rod is opened on the inner wall of the positioning hole. A stop block is horizontally fixed at the top of the vertical groove.

[0009] The top of the L-shaped rod is a bevel, and the top of the L-shaped rod extends to the top of the positioning hole;

[0010] The bottom of the positioning hole is equipped with a marking mechanism for marking the installation position.

[0011] Preferably, the L-shaped rod is made of elastic plastic and can slide vertically along the vertical groove. The inner side of the L-shaped rod is in contact with the outer side of the stop block, and the protruding position at the top of the L-shaped rod is on the same vertical plane as the inner side of the vertical groove.

[0012] Preferably, the marking mechanism includes a pressure ring, a sponge ring, a second spring, and a protective component. The pressure ring is slidably disposed at the bottom of the positioning hole. A second spring is connected between the pressure ring and the bottom of the positioning hole. In the reset state, the bottom of the pressure ring protrudes below the positioning hole. A sponge ring is provided at the bottom of the pressure ring, and pigment powder is provided inside the sponge ring. A protective component is provided at the bottom of the circuit breaker to prevent the sponge ring from being marked incorrectly.

[0013] Preferably, the protective component includes a cover, a pigment tank, a block, and a slot. The cover is attached to the bottom of the circuit breaker and clipped onto both sides of the circuit breaker. The inner side of the cover is symmetrically provided with blocks. The two ends of the cover are provided with pigment tanks at the positions corresponding to the foam rings. The two sides of the circuit breaker are provided with slots that cooperate with the blocks.

[0014] Preferably, the card block and the card slot are interference fit, and the card block is made of elastic rubber material.

[0015] Preferably, the first spring is sleeved on the outside of the inner threaded tube, and the two ends of the first spring are fixedly connected to the upper pressure ring and the inner wall of the positioning hole, respectively.

[0016] Preferably, the two ends of the second spring are fixedly connected to the bottom of the lower pressure ring and the positioning hole, respectively, and the outer side of the lower pressure ring is in contact with the inner wall of the positioning hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model utilizes the synergistic effect of the upper pressure ring, first spring, L-shaped rod, vertical groove, and stop block within the positioning hole. During bolt installation, the upper pressure ring moves downward synchronously. When the bolt installation torque reaches the preset value, the L-shaped rod moves below the stop block, and its own elasticity causes it to make a sound when resetting, thus providing clear installation feedback. This effectively avoids the problem of wire vibration and loosening caused by insufficient torque, and greatly enhances the stability of the device installation and the safety of use.

[0019] 2. This utility model utilizes a combination structure of a bottom pressure ring at the positioning hole, a sponge ring, and a second spring. The sponge ring contains pigment powder, and the bottom end of the pressure ring is located outside the mounting hole when in the reset state. During installation, the circuit breaker is placed against the mounting position, and the pigment powder in the sponge ring can directly mark the installation position, significantly improving installation efficiency. At the same time, the protective components consisting of a cover, pigment tank, card block, and card slot can prevent mismarking in the non-installation state, further enhancing the practicality of the device.

[0031] Example 1

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an electrical cabinet circuit control and energy-saving optimization device, including a circuit breaker 1. The top and bottom of the circuit breaker 1 are provided with positioning holes 2. An internal threaded tube 3 is fixed on the inner wall of the positioning hole 2. An upper pressure ring 4 is vertically slidably arranged on the inner top of the positioning hole 2. A first spring 5 is connected between the upper pressure ring 4 and the inside of the positioning hole 2.

[0033] An L-shaped rod 6 is vertically fixed on one side of the upper pressure ring 4. A vertical groove 7 adapted to the L-shaped rod 6 is opened on the inner wall of the positioning hole 2. A stop block 8 is horizontally fixed at the top of the inner wall of the vertical groove 7.

[0034] The top of the L-shaped rod 6 is a bevel, and the top of the L-shaped rod 6 extends to the top of the positioning hole 2. The L-shaped rod 6 is made of polyoxymethylene (POM) material (elastic modulus 3.0 GPa), with a cross-sectional dimension of 8 mm width × 3 mm thickness. The bevel angle at the top is 30°. The distance between the lower edge of the stop block 8 and the top of the positioning hole 2 is 12 mm. The torque increases by 2 N·m for every 1 mm the bolt is screwed in. When screwed in 10 mm, the torque reaches 20 N·m. At this time, the top of the L-shaped rod 6 just slides past the stop block 8.

[0035] The bottom of the positioning hole 2 is equipped with a marking mechanism for marking the installation position.

[0036] Before installation, remove the obstruction of the calibration mechanism, attach the circuit breaker 1 to the installation position, use the marking mechanism to quickly mark the installation position, and then drill holes at the marked position.

[0037] When the bolt is installed through the inner threaded tube 3, the bottom end of the bolt will press the upper pressure ring 4 to slide vertically downward along the inner wall of the positioning hole 2. At this time, the upper pressure ring 4 will compress the first spring 5 and drive the L-shaped rod 6 to slide down the vertical groove 7 in sync. Since the top of the L-shaped rod 6 is inclined and its inner side is in contact with the outer side of the stop block 8, the L-shaped rod 6 will undergo slight deformation due to the obstruction of the stop block 8 during the downward movement. When the bolt installation torque reaches the preset value, the top of the L-shaped rod 6 will completely slide past the stop block 8. At this time, the L-shaped rod 6 will return to its original position due to its own elasticity, and its top will collide with the stop block 8 to produce a sound, thereby indicating that the bolt installation torque is up to standard and avoiding the wire from becoming loose due to insufficient torque.

[0038] Example 2

[0039] The solution in Example 1 will be further described below with reference to its specific working method.

[0040] like Figure 3 As shown, in a preferred embodiment, based on the above method, the L-shaped rod 6 is further made of elastic plastic and can slide vertically along the vertical groove 7. The inner side of the L-shaped rod 6 is in contact with the outer side of the stop block 8, and the protruding position of the top of the L-shaped rod 6 is located in the same vertical plane as the inner side of the vertical groove 7.

[0041] The L-shaped rod 6 is made of elastic plastic to ensure both stability and elastic recovery when sliding along the vertical groove 7. The protruding part at the top of the L-shaped rod 6 is on the same vertical plane as the inner side of the vertical groove 7, ensuring precise cooperation with the stop block 8 during the downward movement and ensuring reliable sound feedback when the torque is up to standard.

[0042] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the marking mechanism further includes a pressure ring 9, a sponge ring 10, a second spring 11, and a protective component 12. The pressure ring 9 is slidably disposed at the bottom of the positioning hole 2. The second spring 11 is connected between the pressure ring 9 and the bottom of the positioning hole 2. In the reset state, the bottom of the pressure ring 9 protrudes below the positioning hole 2. The bottom of the pressure ring 9 is provided with a sponge ring 10. The sponge ring 10 is filled with pigment powder. The sponge ring 10 is a high-density polyurethane sponge (density 0.3g / cm³), with an outer diameter of 10mm and a thickness of 5mm. It contains iron oxide red pigment powder (particle size 8μm) and has an adhesion to metal / plastic surfaces ≥24h. The bottom of the circuit breaker 1 is provided with a protective component 12 to prevent the sponge ring 10 from being mismarked.

[0043] During installation, first remove the protective component 12 to remove the obstruction of the sponge ring 10. In the reset state, the bottom of the pressure ring 9 protrudes below the positioning hole 2 due to the support of the second spring 11. At this time, the sponge ring 10 is exposed. When the circuit breaker 1 is attached to the mounting surface, the pressure ring 9 is pressed upward by the mounting surface and compresses the second spring 11. The sponge ring 10 contacts the mounting surface, and the pigment powder inside will leave a mark, realizing the quick determination of the installation position. The elastic coefficient of the second spring 11 is 3N / mm, and the compression stroke is 5mm, ensuring that the contact pressure between the sponge ring 10 and the mounting surface is 12N, which can clearly mark without overflowing pigment.

[0044] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the protective component 12 further includes a cover 1201, a pigment tank 1202, a block 1203, and a slot 1204. The cover 1201 is attached to the bottom of the circuit breaker 1 and is clipped to both sides of the circuit breaker 1. The block 1203 is symmetrically provided on the inner side of the cover 1201. The pigment tank 1202 is provided at both ends of the cover 1201 corresponding to the position of the sponge ring 10. The slots 1204 that cooperate with the block 1203 are provided on both sides of the circuit breaker 1.

[0045] The pigment tanks 1202 at both ends of the cover 1201 correspond to the positions of the sponge ring 10. When not in use, the cover 1201 covers the sponge ring 10 to prevent pigment powder from leaking due to accidental contact and causing mismarking. When installing, the cover 1201 is removed, and the pigment tanks 1202 do not affect the contact between the sponge ring 10 and the mounting surface.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, the card block 1203 and the card slot 1204 are further designed to be interference fit, and the card block 1203 is made of elastic rubber material to ensure that the card cover 1201 fits tightly with the bottom of the circuit breaker 1.

[0047] like Figure 3 As shown, in a preferred embodiment, based on the above method, the first spring 5 is further sleeved on the outside of the inner threaded tube 3. The two ends of the first spring 5 are fixedly connected to the upper pressure ring 4 and the inner wall of the positioning hole 2, respectively. The first spring 5 is sleeved on the outside of the inner threaded tube 3, and the two ends are fixed to the upper pressure ring 4 and the inner wall of the positioning hole 2, respectively. This provides a restoring force for the upper pressure ring 4 and avoids the spring from shifting and affecting the bolt installation.

[0048] like Figure 3 As shown, in a preferred embodiment, based on the above method, the two ends of the second spring 11 are fixedly connected to the bottom of the lower pressure ring 9 and the positioning hole 2 respectively, and the outer side of the lower pressure ring 9 is in contact with the inner wall of the positioning hole 2 to ensure that the lower pressure ring 9 can only slide vertically and to ensure the accuracy of the calibration position.

[0049] Example 3

[0050] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0051] Preparation before installation: The cover 1201 of the protective component 12 is fixed to the bottom of the circuit breaker 1 by the interference fit between the cover 1203 and the slot 1204. At this time, the cover 1201 covers the sponge ring 10 to prevent mismarking in the non-installation state. The second spring 11 supports the lower pressure ring 9 to keep the sponge ring 10 in the standby state. The first spring 5 supports the upper pressure ring 4 and the L-shaped rod 6 to reset. The top of the L-shaped rod 6 protrudes from the top of the positioning hole 2.

[0052] Installation position marking: Remove the cover 1201, attach the circuit breaker 1 to the preset installation position, the mounting surface will press the pressure ring 9 to move upward along the inner wall of the positioning hole 2, the second spring 11 will be compressed, the sponge ring 10 at the bottom of the pressure ring 9 will contact the mounting surface, and the pigment powder inside will adhere to the mounting surface, thus completing the installation position marking. After marking, release the circuit breaker 1, the second spring 11 will reset and drive the pressure ring 9 to move downward, the sponge ring 10 will detach from the mounting surface, and then drill holes at the marked position.

[0053] Bolt fixing and torque feedback: Pass the bolt through the marked mounting hole and screw it into the internal thread tube 3. The bottom end of the bolt presses the upper pressure ring 4 to move down. The first spring 5 is compressed and drives the L-shaped rod 6 to slide down the vertical groove 7. The L-shaped rod 6 is deformed due to the block 8. When the bolt torque reaches the standard, the top of the L-shaped rod 6 slides past the block 8, and after elastic reset, it collides with the block 8 and makes a sound, indicating that the installation is secure.

[0054] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
