Description

Technical Field

[0001] This invention belongs to the technical field of mobile relay protection devices, and more specifically, relates to a mobile relay protection device that is easy to move. Background Technology

[0002] A relay protector is a comprehensive relay protection device based on microprocessor design, integrating inverse-time and definite-time relay protection. Relay protectors are often used to provide safety protection for electrical equipment, such as transformers, motors, generators, and short-circuit and grounding failure protection for power distribution system transmission lines. To facilitate their movement during use, they require a suitable mobile support frame.

[0003] Existing relay protection mobile racks often require a large base to ensure better stability when carrying and moving relay protection devices. However, a large base is inconvenient for portable movement in confined areas such as mountainous regions, thus limiting its use. Furthermore, it cannot be quickly reshaped to accommodate different environments during movement, further limiting its functionality.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a mobile relay protection device that is easy to move, in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a mobile relay protector frame that is easy to move, thus solving the limitation of existing frames that cannot be quickly reshaped for use in different environments.

[0006] The present invention provides a convenient mobile relay protection device frame with the purpose and effect of including a base. The main body of the base is a rectangular structure, and the interior of the base has two transverse grooves arranged in a straight line array. There are two bases in total, and the two bases are axially connected. The transverse grooves in the base are all unidirectional through structures, and two base plates are installed opposite each other on the outer side of each base. The outer side of the base plate is also equipped with a moving wheel. The base and the base plate together form a load-bearing structure for the moving wheel. The base plate and the base are connected by a torsion spring.

[0007] Furthermore, the bearing box has through slots on both the left and right sides, and baffles are installed inside the through slots on both the left and right sides of the bearing box. The baffles are normally in a closed state for the bearing box. The baffles and the bearing box together form a bearing structure for the relay protector. A bracket is fixedly connected to the inside of the bearing box.

[0008] Furthermore, a slide block is slidably connected inside the transverse groove in the base. The slide block has an installation hole inside, and a top plate is fixedly connected to the side of the slide block near the bottom plate. The top plate matches the bottom plate. When the slide block is close to the bottom plate, the top plate is in a state of pushing the bottom plate out and flipping it over.

[0009] Furthermore, a mounting base is installed at the top of each pair of horizontally adjacent connecting rods, and a carrier box is fixedly connected to the top of the mounting base. The carrier box is used to carry the relay protector, and an airbag is installed on the bottom surface of the carrier box. The airbag and the carrier box together form a pumping structure, and the airbag is in a compressed state when the carrier box is close to the base.

[0010] Furthermore, the support has four locations, with each pair of horizontally adjacent supports forming a group. The two groups of supports are fixedly connected to the front and rear sides inside the carrier box. A cover plate is installed on the top of the carrier box. The cover plate and the carrier box are magnetically connected. Air ducts are arranged in a straight line on the right side of the cover plate. The cover plate is connected to the airbag through a flexible hose. When the airbag is in a contracted state, the air ducts on the outside of the cover plate are in an air-discharging state.

[0011] Furthermore, a limit bolt is installed at the front end of the slide block, which is used to limit the position of the slide block inside the base. The slide block and the base are connected by a spring rod. The base and the spring rod together form a traction structure for the slide block. A connecting rod is installed at the top of the slide block.

[0012] The beneficial effects of the present invention are as follows: 1. In the present invention, when gas enters the inner side of the cover plate through the hose, the airflow can be quickly blown into the interior of the carrier box through the air duct opened on the outer side of the cover plate. When the gas enters the interior of the carrier box, the baffle can be opened by the airflow, and the dust in the relay protector can be quickly removed by the airflow, so as to avoid the normal use of the relay protector due to the presence of dust.

[0013] 2. In this invention, when the two slides move outward, the top plate fixedly connected to their outer sides will extrude the base plate and the moving wheel installed on the outer side of the base together. The slides are then fixed by the limit bolts installed on the base and the slides. At this time, the moving wheel can be flipped out of the base by the push-out of the top plate, thereby facilitating the movement of the relay protector. When the device needs to be folded and stored, the two bases can be folded inward at the same time, and the connecting rod can be brought as close as possible to store the device. This allows the user to move and relocate the device more conveniently, thus achieving a more practical purpose.

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0020] Example 1, as shown in the attached document Figure 1 To be continued Figure 4As shown: This invention provides a convenient mobile relay protection device frame, including a base 1. The main body of the base 1 is rectangular, and two transverse slots are arranged in a linear array inside the base 1. There are two bases 1, and the two bases 1 are axially connected. The transverse slots in the base 1 are all unidirectional through structures. Two base plates 2 are installed opposite each other on the outer side of each base 1. The outer side of the base plate 2 is also equipped with a moving wheel 3. The base 1 and the base plate 2 together form a load-bearing structure for the moving wheel 3. The base plate 2 and the base 1 are connected by a torsion spring. There are four brackets 12, and every two transversely adjacent brackets 12 form a group. The two groups of brackets 12 are fixedly connected opposite each other to the front and rear sides of the inside of the carrier box 9. A cover plate 13 is installed on the top of the carrier box 9. The cover plate 13 is magnetically connected to the carrier box 9. The right side of the cover plate 13 has air ducts 14 arranged in a linear array. 13 is connected to the airbag 10 via a hose. When the airbag 10 is in a contracted state, the air duct 14 on the outside of the cover plate 13 is in an air-out state. When the two slides 4 move outward, the top plate 5 fixedly connected to their outer sides will expel the base plate 2 and the moving wheel 3 installed on the outside of the base 1 together. The slide 4 can be limited and fixed by installing the limit bolt 6 on the base 1 and the slide 4. At this time, the moving wheel 3 can be flipped out of the base 1 by the push of the top plate 5, thereby facilitating the movement of the relay protector. When the device needs to be folded and stored, the two bases 1 can be folded inward at the same time, and the connecting rod 8 can be brought as close as possible to the storage to fold and store the whole device. This makes it easier for the user to move and displace the whole device, thereby achieving a more practical purpose.

[0021] refer to Figures 1-2 A slide block 4 is slidably connected inside the transverse groove in the base 1. The slide block 4 has mounting holes inside, and a top plate 5 is fixedly connected to the side of the slide block 4 closest to the base plate 2. The top plate 5 matches the base plate 2. When the slide block 4 is close to the base plate 2, the top plate 5 pushes the base plate 2 out and flips it over. A limit bolt 6 is installed at the front end of the slide block 4 to limit its position inside the base 1. The slide block 4 and the base 1 are connected by a spring rod 7. The base 1 and the spring rod 7 together form a traction structure for the slide block 4. The structure includes a connecting rod 8 installed at the top of the slide 4. When gas enters the inside of the cover plate 13 through the hose, it can simultaneously blow airflow into the interior of the carrier box 9 through the air duct 14 opened on the outside of the cover plate 13. When the gas enters the interior of the carrier box 9, it can not only push open the baffle 11 through the airflow, but also quickly remove dust from the relay protector through the blowing of the airflow, thereby avoiding the problem of the relay protector being affected by the presence of dust.

[0022] refer to Figures 1-4 Mounting base 15 is installed at the top of each pair of horizontally adjacent connecting rods 8. The top of mounting base 15 is fixedly connected to a bearing box 9. The bearing box 9 is used to support the relay protector. An air bladder 10 is installed on the bottom surface of the bearing box 9. The air bladder 10 and the bearing box 9 together form a pumping structure. When the bearing box 9 is close to the base 1, the air bladder 10 is in a compressed state. The left and right sides of the bearing box 9 are provided with through slots. Baffles 11 are installed inside the through slots on the left and right sides of the bearing box 9. The baffles 11 are normally in a closed state for the bearing box 9. The baffles 11 and the bearing box 9 together form a bearing structure for the relay protector. A bracket 12 is fixedly connected to the inside of the bearing box 9.

[0023] The specific usage and function of this embodiment are as follows:

[0024] When using this device, firstly, when it is necessary to place the relay protector, the relay protector can be placed on the bracket 12 fixedly connected to the inside of the carrier box 9, and the cover plate 13 installed on the top of the carrier box 9 can be flipped over and covered on the carrier box 9 to support the relay protector.

[0025] When it is necessary to relocate the relay protection device carried in the carrier box 9, the carrier box 9 can be pressed down to drive the connecting rod 8 installed in the mounting base 15 to move the two sliding blocks 4 outward along the transverse groove opened in the base 1.

[0026] When the two slides 4 move outward, the top plate 5 fixedly connected to their outer side will extrude the base plate 2 and the moving wheel 3 installed on the outer side of the base 1 together. The slide 4 can be fixed by installing the limit bolt 6 on the base 1 and the slide 4. At this time, the moving wheel 3 can be protruded from the base 1 by flipping through the top plate 5, thereby facilitating the movement of the relay protector.

[0027] When the device needs to be folded and stored, the two bases 1 can be folded inwards at the same time, and the connecting rod 8 can be brought as close as possible to the storage area to fold and store the entire device. This makes it easier for users to move and relocate the entire device, thus achieving a more practical purpose.

[0028] When the device is moved, if the relay protector is placed from outdoors into the carrier box 9, and if the relay protector is covered with a lot of dust, the airbag 10 installed at the bottom of the carrier box 9 can be squeezed. When the airbag 10 is squeezed, the air will be pumped into the cover plate 13 through the hose through the contraction of the airbag 10.

[0029] When the gas enters the inside of the cover plate 13 through the hose, the airflow can be simultaneously blown into the inside of the carrier box 9 through the air duct 14 opened on the outside of the cover plate 13. When the gas enters the inside of the carrier box 9, the airflow can not only push open the baffle 11, but also quickly remove the dust in the relay protector, thereby avoiding the problem of the relay protector being affected by the presence of dust.
