Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to a power acquisition device that can be quickly replaced and repaired. Background Technology

[0002] Power data acquisition devices are intelligent devices controlled by microprocessors and are one of the main components of data collection systems. They are widely used in substations, distribution cabinets, and other applications to monitor power parameters such as voltage and current in real time.

[0003] However, traditional power acquisition devices typically use expansion bolts for installation and require independent wiring. When replacing a power acquisition device, each bolt must be removed individually, and multiple lines must be independently disassembled and reconnected. This process is time-consuming and affects the efficiency of power system maintenance. Furthermore, with long-term use, the bolts are prone to rust and become difficult to remove, further impacting disassembly and assembly efficiency. During assembly, multiple wires need to be manually reconnected, which can easily lead to poor wiring contact or incorrect connections, affecting data acquisition accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a power acquisition device that can be quickly replaced and repaired to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a power acquisition device that can be quickly replaced and maintained, comprising: an acquisition device body, a display screen mounted on the front side of the acquisition device body, and junction boxes fixedly connected to both the upper and lower ends of the acquisition device body; The assembly frame has assembly slots that are compatible with the main body of the acquisition device and the two junction boxes. Assembly blocks are fixedly connected to the four corners of the assembly frame, and assembly holes for inserting fixing bolts are provided on the assembly blocks. Two fixing parts are symmetrically arranged on both sides of the assembly frame and the main body of the acquisition device; The positioning part is symmetrically installed on the upper and lower sides of the assembly frame and abuts against the body of the acquisition device; The power receiving part is symmetrically mounted on the assembly frame and the two wiring terminals, wherein: After the main body of the data acquisition device is pushed into the assembly slot, the two fixing parts approach each other and abut against the main body of the data acquisition device, and the two electrical connection parts respectively contact the two junction boxes.

[0006] Furthermore, the fixing part includes a control plate disposed on one side of the assembly frame; two fixing rods symmetrically fixed on the control plate, both penetrating the assembly frame and extending into the assembly slot; two fixing slots symmetrically opened on one side of the acquisition device body, corresponding to the two fixing rods respectively; and two tower-shaped springs whose two ends are fixedly connected to the outer wall of the assembly frame and the control plate respectively, and movably sleeved on the outside of the two fixing rods respectively.

[0007] Furthermore, the fixing part also includes a plurality of storage slots symmetrically formed on the inner wall of the assembly slot; a plurality of return springs respectively fixedly connected in the plurality of storage slots; a fixed roller rotatably mounted on the control plate; a rubber sleeve fixedly sleeved on the outside of the fixed roller; and a slot formed on the body of the acquisition device and adapted to the fixed roller.

[0008] Furthermore, the fixing part also includes two limiting rods symmetrically fixed on one side of the assembly frame; The other ends of both limiting rods pass through the control plate and are fixedly connected to limiting blocks.

[0009] Furthermore, the power receiving part includes a plurality of power receiving slots equally spaced on the rear sides of the two junction boxes, a plurality of conductive copper sheets respectively installed in the plurality of power receiving slots and electrically connected to the main body of the acquisition device, a plurality of power receiving bases equally spaced on the upper and lower sides of the assembly slot and adapted to the plurality of power receiving slots, a plurality of power receiving springs respectively installed on the plurality of power receiving bases and corresponding one-to-one with the plurality of conductive copper sheets, and two terminal blocks symmetrically fixed on the upper and lower sides of the assembly frame, a plurality of power receiving terminals respectively installed on the two terminal blocks and electrically connected to the plurality of power receiving springs respectively.

[0010] Furthermore, the positioning part includes a plurality of positioning rods symmetrically fixed on the upper and lower sides of the assembly frame; and a plurality of positioning blocks rotatably connected to the front ends of the plurality of positioning rods and abutting against the front surface of the acquisition device body.

[0011] Furthermore, the rear surfaces of both junction boxes are fixedly connected with sealing rings that abut against the inner wall of the assembly slot.

[0012] Furthermore, the assembly frame is provided with a plurality of honeycomb slots, and the rear side of the collection device body is provided with heat dissipation slots corresponding to the plurality of honeycomb slots. When some of the assembly blocks are in contact with the mounting plane, the rear side of the assembly frame is not in contact with the mounting plane.

[0013] Compared with the prior art, the embodiments of this utility model have the following beneficial effects: This quick-replacement and repairable power acquisition device, through its two fixed parts, allows for rapid assembly of the acquisition device body. When the acquisition device body is pushed into the assembly slot along the assembly frame, the elastic force of several tower-shaped springs pulls two rollers and several fixed rods into two slots and several fixed slots respectively, thus achieving rapid assembly of the acquisition device body. Simultaneously, when the control plates on both sides are pulled outward, the fixed rods and two fixed rollers disengage from their locked positions. Under the push of the spring plates of several return springs, the acquisition device body can be directly pulled out, allowing the acquisition device to be easily disassembled. Tightening the bolts and pushing the acquisition device body into the assembly slot completes the locking process. Pulling the two control plates apart completes the disassembly process, ensuring efficient disassembly and assembly of the acquisition device body and facilitating rapid replacement in case of failure. This quick-replacement and repairable power acquisition device, through its connection part, allows the conductive copper plates in the two junction boxes to elastically contact the connection springs on the mounting frame when the acquisition device body is installed in the assembly slot via two fixing parts. Current flows through the terminal block to the external circuit, achieving tool-free power connection. When the acquisition device body is pulled out, the connection springs automatically spring back and separate from the conductive copper plates, achieving rapid power disconnection and avoiding the risk of arcing. Compared to the traditional method of tightening and loosening each terminal with a screwdriver, electrical connection and disconnection can be quickly completed during the disassembly and assembly of the acquisition device body, effectively improving power connection efficiency, achieving plug-and-play functionality, eliminating the need for wiring disassembly and assembly, and avoiding potential wiring errors during disassembly and assembly.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1-6 As shown, a power acquisition device that can be quickly replaced and repaired includes: an acquisition device body 1, a display screen 2 installed on the front side of the acquisition device body 1, and junction boxes 3 fixedly connected to both the upper and lower ends of the acquisition device body 1. Assembly frame 4, the assembly frame 4 is provided with assembly slots 5 adapted to the main body 1 of the acquisition device and the two junction boxes 3, and assembly blocks 7 are fixedly connected at the four corners of the assembly frame 4, and assembly holes 8 for inserting fixing bolts are provided on several of the assembly blocks 7. Fixing parts 9, two of the fixing parts 9 are symmetrically arranged on both sides of the assembly frame 4 and the collection device body 1; The positioning part 10 is symmetrically installed on the upper and lower sides of the assembly frame 4 and abuts against the body 1 of the acquisition device; The power receiving part 11 is symmetrically mounted on the assembly frame 4 and the two wiring terminals, wherein: After the main body 1 of the data acquisition device is pushed into the assembly slot 5, the two fixing parts 9 approach each other and abut against the main body 1 of the data acquisition device, and the two electrical connection parts 11 respectively contact the two junction boxes 3. When assembling the main body 1 of the data acquisition device, push the main body 1 of the data acquisition device into the assembly slot 5 of the assembly frame 4. The sealing rings 31 on the two junction boxes 3 are in contact with the wall of the assembly slot 5 to ensure dust and water resistance. At this time, several positioning blocks 30 of the positioning part 10 rotate and press against the front surface of the acquisition device body 1 to prevent back and forth shaking. During the process of pushing the main body 1 of the data acquisition device into the assembly slot 5, the two fixed rollers 18 are simultaneously squeezed on both sides of the main body 1, pushing the two control plates 12 to move outward and stretching several tower springs 15. When the main body 1 of the data acquisition device is pushed to the bottom, the two rollers are aligned with the two slots 20, and the several tower springs 15 release their elasticity, driving several fixed rods 13 to insert into several fixed slots 14, thus completing the rapid and stable assembly of the main body 1 of the data acquisition device in the assembly slot 5 and ensuring the assembly efficiency of the main body 1 of the data acquisition device. While the main body 1 of the data acquisition device is assembled in the assembly slot 5, the power receiving part 11 works in coordination. Several conductive copper sheets 24 of the two junction boxes 3 make elastic contact with several power receiving spring sheets 26 on the assembly frame 4. The current flows through the terminal block 27 to the external line, realizing tool-free power supply, so that the insertion, fixing and power supply of the main body 1 of the data acquisition device are completed simultaneously. When the main body 1 of the data acquisition device needs to be replaced or repaired, simply pull out both control plates 12 on both sides at the same time to disengage several fixed rods 13 from the two fixed rollers 18 from their locked positions. This allows the data acquisition device to be pulled out directly and several conductive copper discs to be disconnected from several contact springs 26. There is no need to remove bolts or rewire, which ensures the disassembly efficiency of the main body 1 of the data acquisition device and facilitates quick replacement in case of failure. Furthermore, there is no need to rewire during disassembly and assembly, which avoids incorrect wiring or poor contact and ensures the accuracy of data acquisition.

[0019] Optionally, the fixing part 9 includes a control plate 12 disposed on one side of the assembly frame 4; two fixing rods 13 symmetrically fixed on the control plate 12, both penetrating the assembly frame 4 and extending into the assembly groove 5; two fixing grooves 14 symmetrically opened on one side of the acquisition device body 1 and corresponding to the two fixing rods 13 respectively; and two tower-shaped springs 15 whose two ends are fixedly connected to the outer wall of the assembly frame 4 and the control plate 12 respectively, and movably sleeved on the outside of the two fixing rods 13 respectively.

[0020] Optionally, the fixing part 9 further includes a plurality of storage slots 16 symmetrically opened on the inner wall of the assembly slot 5; a plurality of return springs 17 respectively fixedly connected in the plurality of storage slots 16; a fixed roller 18 rotatably mounted on the control plate 12; a rubber sleeve 19 fixedly sleeved on the outside of the fixed roller 18; and a slot 20 opened on the collection device body 1 and adapted to the fixed roller 18. When the data acquisition device body 1 is installed near the assembly frame 4, it simultaneously compresses the two fixed rollers 18 in the two fixed parts 9, pushing the two control plates 12 in the two fixed parts 9 away from each other and causing the tower springs 15 in the two fixed parts 9 to stretch and deform. Then, when the data acquisition device body 1 is fully inserted, several return springs 17 are compressed into several storage slots 16. The two fixed rollers 18 are respectively aligned with the two slots 20, and several fixed rods 13 are respectively aligned with several fixed slots 14. After the tower springs 15 release their elasticity, they pull the control plates 12 to reset, the two fixed rollers 18 are locked into the two slots 20, and several fixed rods 13 are respectively inserted into several fixed slots 14, forming an axial and radial double locking, effectively restricting the movement of the data acquisition device body 1 in the assembly slot 5, ensuring the stable connection of the power connection part 11. Moreover, the fixed part 9 can be triggered simply by pushing the data acquisition device into the assembly slot 5, without additional operation, realizing "insertion and locking". The rollers on both sides are pressed simultaneously, avoiding the equipment tilting caused by unilateral stress, and ensuring the insertion of the power connection part 11. With the terminals aligned, the rubber sleeves 19 on the outside of the two fixed rollers 18 and the frictional engagement with the two slots 20 respectively effectively improve the vibration resistance of the data acquisition device body 1 in the assembly slot 5. When it is necessary to remove the data acquisition device body 1, manually pull the control plates 12 on both sides outward, the two fixed rollers 18 disengage from the two slots 20, and several fixed rods 13 exit from several fixed slots 14, thus unlocking. At this time, under the elastic force of several return springs 17, the data acquisition device body 1 moves horizontally in the assembly slot 5, partially retracting from the assembly slot 5, so that the two fixed rollers 18 and several fixed rods 13 are misaligned with the two slots 20 and several fixed slots 14 respectively, and the data acquisition device body 1 can be quickly removed from the assembly slot 5. Only one person is needed to quickly complete the disassembly and assembly of the data acquisition device, ensuring the efficiency of disassembly and replacement of the data acquisition device body 1, facilitating the maintenance of the data acquisition device, and making it easy to use. And through the cooperation of the two fixed parts 9 for fixation, if one fixed part 9 fails, the other side can still provide basic fixing force through the fixed part 9, and the redundant design improves safety.

[0021] Optionally, the fixing part 9 may also include two limiting rods 21 symmetrically fixed on one side of the assembly frame 4; The other ends of the two limiting rods 21 pass through the control plate 12 and are fixedly connected to the limiting block 22. The two limiting rods 21 passing through the control plate 12, together with the two limiting blocks 22, can effectively limit the movement stroke of the control plate 12, avoid excessive pressing or pulling that would cause plastic deformation of the tower spring 15, protect the elasticity of the spring, and improve the stability of the movement of the control plate 12, ensuring that the two fixing rods 13 are fully inserted into the two fixing slots 14, and avoiding loose connections.

[0022] Optionally, the power receiving part 11 includes a plurality of power receiving slots 23 equally spaced on the rear side of the two junction boxes 3, a plurality of conductive copper sheets 24 respectively installed in the plurality of power receiving slots 23 and electrically connected to the main body of the acquisition device 1, a plurality of power receiving bases 25 equally spaced on the upper and lower sides of the assembly slot 5 and adapted to the plurality of power receiving slots 23, a plurality of power receiving springs 26 respectively installed on the plurality of power receiving bases 25 and corresponding one-to-one with the plurality of conductive copper sheets 24, and two terminal blocks 27 symmetrically fixed on the upper and lower sides of the assembly frame 4, a plurality of power receiving terminals 28 respectively installed on the two terminal blocks 27 and electrically connected to the plurality of power receiving springs 26. When the main body 1 of the data acquisition device is pushed into the assembly slot 5 and fixed in place by the fixing part 9, several electrical connection slots 23 on the two junction boxes 3 automatically align with the electrical connection bases 25, and several conductive copper sheets 24 contact the electrical connection springs 26. The electrical connection springs 26 are deformed under pressure, forming a stable elastic contact. When external lines are connected to the two terminal blocks 27 through several electrical connection terminals 28, the current flows through the electrical connection springs 26 to the conductive copper sheets 24, and then to the main body 1 of the data acquisition device, completing the power supply or signal transmission. A single terminal block 27 can integrate multiple electrical connection terminals 28, supporting unified access for voltage, current, and communication interfaces. When the main body 1 of the data acquisition device is pushed into the assembly slot 5, the electrical connection slots 23 on the two junction boxes 3 automatically align with the electrical connection bases 25, and several conductive copper sheets 24 contact with the electrical connection springs 26. The electrical connection springs 26 are deformed under pressure, forming a stable elastic contact. When external lines are connected to the two terminal blocks 27 through several electrical connection terminals 28, the current flows through the electrical connection springs 26 to the conductive copper sheets 24, and then to the main body 1 of the data acquisition device, completing the power supply or signal transmission. A single terminal block 27 can integrate multiple electrical connection terminals 28, supporting unified access for voltage, current, and communication interfaces. When removed from slot 5, several contact springs 26 automatically spring back and separate from several conductive copper sheets 24, achieving rapid power disconnection and avoiding the risk of arcing. The main body 1 of the power acquisition device can be directly pushed into and removed from the assembly slot 5, which can quickly complete the electrical connection and disconnection. In contrast to the traditional method of tightening and loosening the terminals one by one with a screwdriver, this ensures the efficiency of electrical connection and disconnection when the power acquisition device is quickly disassembled and assembled. In case of damage, only the contact springs 26 or conductive copper sheets 24 need to be replaced, without the need for overall disassembly. When a single line needs to be disassembled, the connection between the line and the corresponding contact terminal 28 can be loosened with a screwdriver, and the line can be removed for inspection.

[0023] Optionally, the positioning part 10 includes a plurality of positioning rods 29 symmetrically fixed on the upper and lower sides of the assembly frame 4; and a plurality of positioning blocks 30 rotatably connected to the front ends of the plurality of positioning rods 29 and abutting against the front surface of the acquisition device body 1. In the initial state, the positioning blocks 30 are at a certain angle to the assembly frame 4 due to a slight preload, and do not obstruct the assembly slot 5. When the acquisition device body 1 is installed in the assembly slot 5 through the fixing part 9, the positioning blocks 30 are rotated to make them fit tightly against the front surface of the acquisition device body 1, forming a physical limit and preventing the acquisition device body 1 from sliding back and forth in the assembly slot 5. In a vibration environment, the spring pressure may periodically decrease, while the mechanical hard contact of the positioning blocks 30 provides continuous limit, improves overall stability, avoids displacement caused by vibration or insertion and extraction force, prevents the acquisition device body 1 from accidentally loosening, and ensures continuous data acquisition.

[0024] Optionally, a sealing ring 31 that abuts against the inner wall of the assembly groove 5 is fixedly connected to the rear surface of both junction boxes 3; The two sealing rings 31 are compressed when the two junction boxes 3 are inserted into the assembly slots 5 to fill the gap between the junction box 3 and the assembly slots 5, effectively preventing dust and water from entering the electrical connection slots 23; at the same time, the rubber material can absorb some vibration energy, playing a shock absorption and buffering effect to protect the internal electrical connection parts 11 of the acquisition device body 1.

[0025] Optionally, the assembly frame 4 is provided with a plurality of honeycomb slots 32, and the rear side of the collection device body 1 is provided with heat dissipation slots 33 corresponding to the plurality of honeycomb slots 32. When several of the assembly blocks 7 are in contact with the mounting surface, the rear side of the assembly frame 4 is not in contact with the mounting surface; during installation, there will be a gap between the assembly frame 4 and the mounting surface to ensure air circulation, thereby facilitating the discharge of heat from the main body 1 of the collection device through several heat dissipation grooves 33 and honeycomb grooves 32, which is beneficial to the long-term normal operation of the equipment 5.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
