Description

Technical Field

[0001] This invention relates to the field of protection cabinet technology, specifically to a relay protection cabinet that is easy to expand and upgrade later, and its usage method. Background Technology

[0002] Relay protection cabinets are commonly used to protect relays and their internal wiring components, maintaining excellent protection. However, with the gradual development of circuits, the number of relays and circuits required has increased. Traditional relay protection cabinets, being integrated units, cannot accommodate the addition of new relays, or adding relays can lead to congestion and tangled wiring, making the operation of the relays within the cabinet extremely dangerous. This can easily cause fires and other extremely dangerous situations, resulting in economic losses. Furthermore, it can pose a threat to personnel health, leaving significant hidden dangers. Directly replacing the relay protection cabinet with a new one is wasteful of materials. The common method for modifying relays involves cutting or disassembling the existing cabinet and then reassembling and welding it, which is time-consuming, labor-intensive, and lacks expansion capabilities, easily limited by the shape of the original protection cabinet.

[0003] Therefore, people have considered using a modular, track-based approach to expand the protective cabinet, achieving simple assembly without being limited by shape and reducing the freedom of assembly. However, the problems that arise are also quite obvious. Although the assembly process is simple, the stability of the assembly needs to be improved. The protective cabinet with the modular structure will lose its overall anti-collision performance, causing the protective cabinet to fail to achieve the specified protection effect. After the assembly is completed, the internal wiring problem is still not solved. Although the installation range of relays is increased, the wires inside the assembled protective cabinet are still placed haphazardly. Moreover, due to the special modular structure, the installation direction and length of the wires will be greatly restricted. Summary of the Invention

[0004] The purpose of this invention is to provide a relay protection cabinet that is easy to expand and upgrade later, and its usage method, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A relay protection cabinet that facilitates future expansion and its usage method is disclosed. The protection cabinet includes: a first protection cabinet, a second protection cabinet, a cable straightening assembly, a fixing buckle, a retracting motor, a wire storage box, and an anti-collision assembly. The first and second protection cabinets are slidably connected. The retracting motor is located at the bottom of the first protection cabinet and is connected to the second protection cabinet. The fixing buckle is located on the second protection cabinet. The cable straightening assembly is located inside the first protection cabinet and is connected to the second protection cabinet. The wire storage box is located on the first protection cabinet. The anti-collision assembly is located on both ends of the first and second protection cabinets respectively. Through this connection, the first and second protection cabinets are connected together by a socket, realizing the expansion function of the double-section protection cabinet. The retracting motor is used to control the expansion degree between the first and second protection cabinets. The retracting motor adopts a servo motor, which has a good effect and can realize the auxiliary positioning function. Together with the fixing buckle, the retracting motor realizes the retraction function of the protection cabinet. The anti-collision assembly works with the extension and retraction of the first and second protection cabinets to achieve the protective effect.

[0007] The first protection cabinet includes: a cover box, a relay mounting platform, and a motor bracket. The cover box contains a cable straightening assembly and a wire storage box, with the wire storage box located below the cable straightening assembly. The relay mounting platform is located inside the cover box and rotates with it. A motor bracket is located at the bottom of the cover box, and a tensioning motor is mounted on the motor bracket. A positioning spring is located on the side of the cover box away from the motor bracket, and the positioning spring is slidably connected to the cover box. A spring is installed between the positioning spring and the cover box, with both ends of the spring abutting against the positioning spring and the inner wall of the cover box, respectively. The second protection cabinet contains a spare mounting platform and is rotatably connected to the second protection cabinet via a spring shaft. The cover box is slidably connected to the second protection cabinet. A toothed mechanism is located on the side of the second protection cabinet near the tensioning motor, and the output end of the tensioning motor meshes with the toothed mechanism on the second protection cabinet. The protective cabinet has a cable-straightening rack on the side near the cable-straightening assembly, which is embedded in the cable-straightening assembly. The second protective cabinet has several positioning slots on the side near the positioning springs, and the shape of the positioning slots matches the shape of the positioning springs. After the retraction motor is started, it will move along the teeth on the second protective cabinet, driving the cover box to move downwards or upwards, thereby changing the space inside the protective cabinet. During the upward movement, the spare mounting platform will pop out from the second protective cabinet, providing a mounting position for the expansion relay. During the upward movement, the positioning springs will pass through the positioning slots on the second protective cabinet in sequence. When it rises to the required position, the positioning springs will be locked in the positioning slots, and the retraction motor will stop working. The cover box will stop moving, and the cable-straightening assembly will also perform automatic cable-straightening operation with the relative movement of the cable-straightening rack.

[0008] The shaping buckle is slidably connected to the second protective cabinet. The shaping buckle is provided with several release protrusions. Each release protrusion is embedded in the positioning groove and slides in contact with the positioning groove. When the first and second protective cabinets need to be retracted, the shaping buckle is pushed down, and the release protrusions will fill the positioning groove. At this time, the positioning spring will not remain in the positioning groove and will continue to descend.

[0009] The wire straightening assembly includes a following gear, a winding wheel rod, and a winding wheel. The following gear is rotatably connected to the cover housing via a bracket. The winding wheel rod is mounted on the following gear and meshes with the wire straightening rack. The rotation axis of the following gear and the rotation axis of the winding wheel rod are on the same straight line. A winding wheel is positioned between the winding wheel rods and is located inside the wire storage box. Excess wire will be wound onto the winding wheel. As the first protective cabinet rises and falls, the wire straightening rack will drive the following gear to rotate. At the same time, the following gear will drive the winding wheel rod, which will cause the wire generated during the rising and falling process to be wound or detached from the winding wheel, reducing the problem of wire accumulation and limited space caused by changes in the space inside the protective cabinet.

[0010] The winding reel includes: a winding tube, winding blocks, a tensioning motor, tensioning springs, tensioning spring clips, and a bevel gear. The winding tube is located between the winding reel rods. The tensioning motor body is fixedly connected to the wire storage box. A bevel gear is provided at the output end of the tensioning motor, and the bevel gear meshes with several tensioning spring clips. The tensioning spring clips are disposed inside the winding tube. The winding tube is fixedly connected to the inner wall of the wire storage box. Several winding blocks are provided on the winding tube, and the winding blocks pass through the winding tube and are slidably connected to the winding tube. Tensioning springs are provided on the winding blocks, with their two ends respectively abutting against the winding blocks and the inner wall of the winding tube. Each winding block has a tension spring at one end near the tensioning motor. The operator can freely adjust the tension of the wires inside the protection cabinet according to the tightness of the wires. After starting the tensioning motor, the motor will drive the bevel gear to move. The threads on the bevel gear will drive the tension spring to move. During the movement, the tension spring will expand outward and press against the winding block. The winding block moves outward, expanding the radius of the winding of the wire, so that the wire gets greater tension during the winding process. If it is necessary to loosen the wire, simply turn the tensioning motor in the opposite direction.

[0011] The anti-collision assembly includes: an upper anti-collision strip, a lower anti-collision strip, an upper anti-collision ring, and a lower anti-collision ring. Multiple upper and lower anti-collision strips are respectively installed on the upper and lower anti-collision rings. Each upper anti-collision strip is rotatably connected to the upper anti-collision ring. The upper anti-collision ring is rotatably connected to the upper end of the first protective cabinet. The upper and lower anti-collision strips are connected by anti-collision springs. Several spring mounting slots are provided on each of the upper and lower anti-collision strips. Protective soft sleeves are installed on both the first and second protective cabinets. When a minor impact occurs, the upper and lower anti-collision strips will offset the impact through their built-in anti-collision springs. When a major impact occurs, the upper and lower anti-collision strips will drive the upper and lower anti-collision rings to move, causing them to rotate and converting the impact force into rotational power, thus largely eliminating the impact force and protecting the protective cabinet. Simultaneously, the entire system is protected against minor scratches from sharp objects.

[0012] The top of the first protective cabinet and the bottom of the second protective cabinet are respectively equipped with conical spiral columns. Multiple balls are set on the threads of the conical spiral columns. The upper anti-collision ring consists of multiple anti-collision sections, each of which is connected by a spring. Each lower anti-collision strip is rotatably connected to an anti-collision section. The upper and lower anti-collision rings have the same structure. The upper and lower anti-collision rings engage with the conical spiral columns on the top of the first protective cabinet and the bottom of the second protective cabinet, respectively. The upper and lower anti-collision rings work together with the conical spiral columns so that after an impact, the upper and lower anti-collision rings will automatically return to their initial state, waiting for the next impact, achieving a cyclical use effect. The addition of balls can enhance the lubrication between the upper and lower anti-collision rings and the conical spiral columns, indirectly strengthening the impact protection effect.

[0013] The second protective cabinet is equipped with a mounting bracket, which is fixedly connected to the ground or mounting platform by bolts. The mounting bracket can also be changed in shape according to the specific installation location and environment. For example, when installed on a pole, the mounting bracket can be replaced with a mounting ring and secured with bolts.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The present invention adopts a pull-out protection cabinet structure, which can realize the longitudinal and lateral extension directions while maintaining the basic shape of the original protection cabinet, providing a stable expansion direction for the development of relays.

[0015] 2. The present invention adopts a follow-up cord-strapping assembly that can automatically follow the cord-strapping process according to the extension process, which is more convenient, reduces some unnecessary structural additions, and can also automatically adjust the cord-strapping intensity according to the changes in the space inside the protection cabinet.

[0016] 3. This invention employs a following anti-collision system that automatically adjusts the anti-collision intensity as the shape of the protective cabinet changes, thus maintaining the structure of the protective cabinet while reducing energy loss. Attached Figure Description

[0029] A relay protection cabinet that facilitates future expansion and its usage method is disclosed. The protection cabinet includes: a first protection cabinet 1, a second protection cabinet 2, a cable winding assembly, a retaining clip 3, a retracting motor 4, a wire storage box 5, and anti-collision components 6. The first protection cabinet 1 and the second protection cabinet 2 are slidably connected. The retracting motor 4 is located at the bottom of the first protection cabinet 1 and is connected to the second protection cabinet 2. The retaining clip 3 is located on the second protection cabinet 2. The cable winding assembly is located inside the first protection cabinet 1 and is connected to the second protection cabinet 2. The wire storage box 5 is located on the first protection cabinet 1. The anti-collision components 6 are located on both sides. The ends are respectively set on the first protective cabinet 1 and the second protective cabinet 2. Through this connection, the first protective cabinet 1 and the second protective cabinet 2 are connected together by a socket, realizing the expansion function of the double-section protective cabinet. The retraction motor 4 is used to control the degree of expansion between the first protective cabinet 1 and the second protective cabinet 2. The retraction motor 4 adopts a servo motor, which has a good effect and can realize the auxiliary positioning function. In conjunction with the shaping buckle 3, the retraction motor 4 realizes the retraction function of the protective cabinet. The anti-collision component 6 works with the extension and retraction of the first protective cabinet 1 and the second protective cabinet 2 to achieve the protective effect.

[0030] The first protective cabinet 1 includes: a cover box 101, a relay mounting platform 102, and a motor bracket 103. The cover box 101 contains a cable straightening assembly and a wire storage box 5, which is located below the cable straightening assembly. The relay mounting platform 102 is located inside the cover box 101 and rotates with it. The motor bracket 103 is located at the bottom of the cover box 101, and a retraction motor 4 is mounted on the motor bracket 103. A positioning spring 104 is located on the side of the cover box 101 away from the motor bracket 103, and is slidably connected to the cover box 101. A spring is located between the positioning spring 104 and the cover box 101, with both ends of the spring abutting against the positioning spring 104 and the inner wall of the cover box 101, respectively. The second protective cabinet 2 contains a spare mounting platform 7, which is rotatably connected to the second protective cabinet 2 via a spring shaft. The cover box 101 is slidably connected to the second protective cabinet 2. A toothed section is located on the side of the second protective cabinet 2 near the retraction motor 4. The output of the retraction motor 4... The end engages with the teeth on the second protective cabinet 2. The second protective cabinet 2 is provided with a winding rack 8 on the side near the winding assembly. The winding rack 8 is embedded in the winding assembly. The second protective cabinet 2 is provided with several positioning slots 9 on the side near the positioning spring 104. The shape of the positioning slots 9 matches the shape of the positioning spring 104. After the retraction motor 4 is started, the retraction motor 4 will move along the teeth on the second protective cabinet 2. The retraction motor 4 will drive the cover box 101 to move down or up, thereby changing the space change inside the protective cabinet. During the upward movement, the spare mounting platform 7 will pop out from the second protective cabinet 2 to provide the mounting position for the expansion relay. During the upward movement, the positioning spring 104 will pass through the positioning slots 9 on the second protective cabinet 2 in sequence. When it rises to the required position, the positioning spring 104 will be locked in the positioning slot 9. At the same time, the retraction motor 4 will stop working, the cover box 101 will stop moving, and the winding assembly will also perform automatic winding operation with the relative movement of the winding rack 8.

[0031] The shaping buckle 3 is slidably connected to the second protective cabinet 2. The shaping buckle 3 is provided with several release protrusions 301. Each release protrusion 301 is embedded in the positioning groove 9 and slides in contact with the positioning groove 9. When the first protective cabinet 1 and the second protective cabinet 2 need to be retracted, the shaping buckle 3 is pushed down, and the release protrusions 301 will fill the positioning groove 9. At this time, the positioning spring 104 will not remain in the positioning groove 9 and will continue to descend.

[0032] The wire straightening assembly includes: a following gear 10, a winding wheel rod 11, and a winding wheel 12. The following gear 10 is rotatably connected to the cover box 101 via a bracket. The winding wheel rod 11 is mounted on the following gear 10. The following gear 10 meshes with the wire straightening rack 8. The rotation axis of the following gear 10 and the rotation axis of the winding wheel rod 11 are on the same straight line. The winding wheel 12 is mounted between the winding wheel rods 11 and is located inside the wire storage box 5. Excess wire will be wound onto the winding wheel 12. As the first protective cabinet 1 rises and falls, the wire straightening rack 8 will drive the following gear 10 to rotate. At the same time, the following gear 10 will drive the winding wheel rod 11. The winding wheel rod 11 will cause the wire generated during the lifting and lowering to be wound or detached from the winding wheel 12, reducing the problem of wire accumulation and limited space caused by changes in the space inside the protective cabinet.

[0033] The winding reel 12 includes: a winding tube 1201, winding blocks 1202, a tensioning motor 1203, tensioning springs 1204, tensioning springs 1205, and a bevel gear 1206. The winding tube 1201 is located between the winding reel rods 11. The body of the tensioning motor 1203 is fixedly connected to the wire storage box 5. The output end of the tensioning motor 1203 is provided with a bevel gear 1206, which meshes with several tensioning springs 1205. The tensioning springs 1205 are disposed inside the winding tube 1201. The winding tube 1201 is fixedly connected to the inner wall of the wire storage box 5. Several winding blocks 1202 are provided on the winding tube 1201. The winding blocks 1202 pass through the winding tube 1201 and are slidably connected to the winding tube 1201. Tensioning springs 1204 are provided on the winding blocks 1202. The two ends of the spring 1204 abut against the inner wall of the winding block 1202 and the winding tube 1201, respectively. The end of each winding block 1202 near the tensioning motor 1203 abuts against the tensioning spring 1205. The operator can freely adjust the tension of the wires inside the protective cabinet according to the tightness of the wires. After starting the tensioning motor 1203, the tensioning motor 1203 will drive the bevel gear 1206 to move. The thread on the bevel gear 1206 will drive the tensioning spring 1205 to move. During the movement, the tensioning spring 1205 will expand outward and abut against the winding block 1202. The winding block 1202 moves outward, expanding the radius of the winding wire, so that the wire gets greater tension during the winding process. If it is necessary to loosen the wire, simply turn the tensioning motor 1203 in the opposite direction.

[0034] The anti-collision component 6 includes: an upper anti-collision strip 601, a lower anti-collision strip 602, an upper anti-collision ring 603, and a lower anti-collision ring 604. Multiple upper anti-collision strips 601 and lower anti-collision strips 602 are respectively provided on the upper anti-collision ring 603 and the lower anti-collision ring 604. Each upper anti-collision strip 601 is rotatably connected to the upper anti-collision ring 603. The upper anti-collision ring 603 is rotatably connected to the upper end of the first protective cabinet 1. The upper anti-collision strip 601 and the lower anti-collision strip 602 are connected by anti-collision springs 606. Multiple spring mounting slots 607 are respectively provided on the upper anti-collision strip 601 and the lower anti-collision strip 602. The first protective cabinet 1 and the second protective cabinet 1... The protective cabinet 2 is equipped with protective soft sleeves 605. When a slight impact occurs, the upper anti-collision strip 601 and the lower anti-collision strip 602 will offset the impact through their built-in anti-collision springs 606. When an impact occurs, the upper anti-collision strip 601 and the lower anti-collision strip 602 will drive the upper anti-collision ring 603 and the lower anti-collision ring 604 to move. The upper anti-collision ring 603 and the lower anti-collision ring 604 will rotate and convert the impact force into rotational power, which will largely eliminate the impact force and protect the protective cabinet. At the same time, it will also protect the entire cabinet and reduce the scratches on the outer shell of the protective cabinet by small sharp objects.

[0035] The top of the first protective cabinet 1 and the bottom of the second protective cabinet 2 are respectively provided with conical spiral columns 14. Multiple balls are provided on the threads of the conical spiral columns 14. The upper anti-collision ring 603 includes multiple anti-collision sections, each of which is connected by a spring. Each lower anti-collision strip 602 is rotatably connected to an anti-collision section. The upper anti-collision ring 603 and the lower anti-collision ring 604 have the same structure. The upper anti-collision ring 603 and the lower anti-collision ring 604 respectively engage with the conical spiral columns on the top of the first protective cabinet 1 and the bottom of the second protective cabinet 2. The upper anti-collision ring 603 and the lower anti-collision ring 604 work together with the conical spiral columns 14 so that after an impact, the upper anti-collision ring 603 and the lower anti-collision ring 604 will automatically return to their initial state and wait for the next impact, achieving a cyclical use effect. The addition of balls can enhance the lubrication of the upper anti-collision ring 603 and the lower anti-collision ring 604 with the conical spiral columns 14, indirectly enhancing the impact protection effect.

[0036] The second protective cabinet 2 is equipped with a mounting bracket 13, which is fixedly connected to the ground or mounting platform by bolts. The mounting bracket 13 can also change shape according to the specific installation location and environment. For example, when it is installed on a pole, the mounting bracket 13 can be replaced with a mounting ring and fastened with bolts.

[0037] The working principle of this invention is as follows: When it is necessary to further expand the number of electrical components such as relays, the retraction motor 4 is started. The retraction motor 4 operates, causing the cover box 101 to rise. The spare mounting platform 7 on the second protection cabinet 2 protrudes under the action of the spring shaft to hold the expanded relays. As the cover box 101 rises, the following gear 10 will rotate with the movement of the winding rack 8, thereby driving the winding wheel rod 11. The winding wheel rod 11 will pull the excess wire from the winding wheel 12. At the same time, according to the specific situation inside the protection cabinet, the tensioning motor 1203 is adjusted. The tensioning motor 1203 operates, driving the bevel gear 1206 to move. The thread on the bevel gear 1206 will drive the tensioning spring 1205 to move. The tensioning spring 1205 moves as it moves. During the process, it expands outward and blocks the winding block 1202. The winding block 1202 moves outward, expanding the radius of the winding wire, so that the wire obtains greater tension during the winding process. If it is necessary to loosen the wire, simply turn the tensioning motor 1203 in the opposite direction. At the same time, after the expansion is completed, adjust the position of the anti-collision spring 606 to maintain the best anti-collision effect. When a slight impact is encountered, the upper anti-collision strip 601 and the lower anti-collision strip 602 will offset the impact through their own anti-collision spring 606. When an impact is encountered, the upper anti-collision strip 601 and the lower anti-collision strip 602 drive the upper anti-collision ring 603 and the lower anti-collision ring 604 to move. The upper anti-collision ring 603 and the lower anti-collision ring 604 will rotate and convert the impact force into rotational power, which largely eliminates the impact force and protects the protective cabinet.

[0038] The steps for using this invention are as follows:

[0039] 1. Determine the type of mounting bracket 13, and install the protective cabinet body using the mounting bracket located on the second protective cabinet 2.

[0040] 2. When it is necessary to expand the space inside the protection cabinet and add relays, start the retraction motor 4. The retraction motor 4 will rotate in the forward direction. When it rises to the required position, turn off the retraction motor 4.

[0041] 3. When it is necessary to compress the protection cabinet and remove the relay, press down the shaping buckle 3 until all of them disengage from the 301 protrusion and enter the positioning groove 9.

[0042] 4. Start the retraction motor 4. The retraction motor 4 rotates in the opposite direction, and the first protection cabinet 1 and the second protection cabinet 2 will retract to their initial state.

[0043] 5. Open the doors of the first protection cabinet 1 and the second protection cabinet 2 to install the expansion relay.

[0044] 6. After the expansion is complete, adjust the position of the anti-collision spring 606.
