Description

Technical Field

[0001] This utility model relates to the field of power grid line simulation technology, and in particular to a multifunctional power distribution network line simulation device. Background Technology

[0002] A multi-functional distribution network line simulation device is a piece of equipment that integrates technologies from multiple fields to simulate various operating states of a distribution network. In the field of power systems, it can assist in the operation and planning of distribution networks, simulating the power flow distribution and voltage quality after the connection of new substations or lines; it can perform fault analysis and processing, simulating the changes in electrical quantities during faults such as short circuits and grounding, providing a basis for relay protection settings and fault handling strategy formulation.

[0003] During the use of the device, heat dissipation is required. When air enters the device, it will bring dust into the device along with it. When using conventional dust filter plates, dust will fall on the filter plates and block the filter holes, affecting the amount of air entering. When the device is not in use, dust will also accumulate on the filter holes of the filter plate, resulting in poor heat dissipation. High temperature will have a negative impact on the electronic components inside the device, accelerate component aging, and may even damage the components, affecting the performance and service life of the device. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional power distribution network line simulation device to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional power distribution network line simulation device, including simulation equipment, and further comprising:

[0006] A heat dissipation mechanism is installed inside the simulation device. The heat dissipation mechanism includes a cylinder installed inside the simulation device. The heat dissipation mechanism is used to dissipate heat from the device when heat dissipation is required. It can automatically close and seal when not in use to prevent dust from entering the device.

[0007] A sealing mechanism is provided inside the simulation device. The sealing mechanism includes a strip sealing plate installed inside the simulation device. The sealing mechanism is used to dissipate the heat generated by the device when it is dissipating heat, and to seal the air outlet when the device stops dissipating heat, thereby further reducing the intrusion of dust.

[0008] Preferably, the heat dissipation mechanism includes a cylinder fixedly installed on the inner wall of the right side of the simulation device, a drive motor fixedly installed on the left side of the cylinder, a rotating shaft rotatably installed through the cylinder, the left end of the rotating shaft being fixedly connected to the output shaft of the drive motor, and a plurality of cooling fan blades fixedly installed on the rotating shaft.

[0009] Preferably, the cylinder has several ventilation holes on its left and right sides, and two cleaning blocks are fixedly installed on the rotating shaft, with the left sides of both cleaning blocks in contact with the cylinder.

[0010] Preferably, a circular groove is provided on the right side of the simulation device, and a dust discharge groove is provided on the bottom inner wall of the circular groove. The right end of the dust discharge groove extends outside the simulation device, and two rectangular sliding grooves are provided inside the circular groove.

[0011] Preferably, the sealing mechanism includes a plurality of limiting springs fixedly installed on the inner walls of two rectangular slides on opposite sides, and two closing plates fixedly installed at the ends of the plurality of limiting springs that are close to each other, with the two closing plates in contact with each other.

[0012] Preferably, a strip sealing plate is fixedly installed on the corresponding closed plate, and a strip sealing groove is opened on the corresponding closed plate. The strip sealing plate extends into the strip sealing groove and slides in connection with the strip sealing groove.

[0014] Preferably, the top and bottom of the T-shaped hollow slide plate are respectively provided with strip-shaped exhaust ducts, and the bottom of the rectangular box is provided with several air inlet ducts.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model:

[0017] 1. When in use, start the drive motor. The drive motor drives the rotating shaft to rotate, which in turn drives several cooling fan blades to rotate. The rotation of the cooling fan blades generates suction force, which in turn drives two cleaning blocks to rotate. The cleaning blocks drive two circular rotating rods to rotate. When the circular rotating rods contact the triangular blocks, the inclined surfaces of the triangular blocks cause the triangular blocks to move away from each other. The triangular blocks then cause the two closed plates to move away from each other. At this time, the limit springs will compress and deform, and the closed plates will slide into the rectangular groove. The circular groove opens, and the suction force will draw outside air into the simulation equipment. Dust will be filtered down by the ventilation holes. During the rotation of the cleaning blocks, the dust accumulated on the ventilation holes will be cleaned off and discharged from the dust exhaust groove. When the device stops running, the cleaning blocks stop rotating, and the corresponding limit springs will drive the closed plates to close under the elastic force. At this time, the strip sealing plate will re-enter the strip sealing groove, thereby improving the sealing performance of the device and effectively preventing dust from entering the device and affecting its operation.

[0018] 2. After air enters the simulation equipment, the air pressure inside the equipment will increase. At this time, the air will enter the rectangular box from the air inlet slot. The air will push the T-shaped hollow slide plate to move away from the rectangular box. At this time, the return spring will be stretched and deformed. When the T-shaped hollow slide plate drives the strip exhaust slot away from the simulation equipment, the air in the rectangular box will be discharged from the strip exhaust slot. At this time, the gas pressure relief and heat dissipation in the simulation equipment are completed. When heat dissipation stops, the return spring will drive the T-shaped hollow slide plate to enter the rectangular box again under the action of elasticity. At this time, the exhaust port of the device forms a seal, further improving the sealing performance of the device. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-6 The multifunctional power distribution network line simulation device shown includes a simulation device 1 and further includes: a heat dissipation mechanism, which is disposed within the simulation device 1 and includes a cylinder 101 disposed within the simulation device 1. The heat dissipation mechanism is used to dissipate heat from the device when heat dissipation is required, and can automatically close and seal when not in use to prevent dust from entering the device; and a sealing mechanism, which is disposed within the simulation device 1 and includes a strip sealing plate 2 disposed within the simulation device 1. The sealing mechanism is used to dissipate the heat generated by the device when heat dissipation is required, and can seal the air outlet when the device stops dissipating heat, further reducing dust intrusion. The heat dissipation mechanism includes a cylinder 101 fixedly installed on the inner right side of the simulation device 1. A drive motor 102 is fixedly installed on the left side of the cylinder 101. A rotating shaft 103 is rotatably installed through the cylinder 101. The left end of the rotating shaft 103 is fixedly connected to the output shaft of the drive motor 102. Several cooling fan blades 104 are fixedly installed on the rotating shaft 103. Several ventilation holes 105 are provided on the left and right sides of the cylinder 101. Two cleaning blocks 106 are fixedly installed on the rotating shaft 103, and the left sides of the two cleaning blocks 106 are in contact with the cylinder 101. A circular groove 107 is provided on the right side of the simulation device 1. A dust discharge groove 108 is provided on the bottom inner wall of the circular groove 107. The right end of the dust discharge groove 108 extends to the outside of the simulation device 1. Two rectangular sliding grooves 109 are provided in the circular groove 107.

[0028] When in use, the drive motor 102 is started, which drives the rotating shaft 103 to rotate. The rotating shaft 103 drives several cooling fan blades 104 to rotate, and the rotation of the cooling fan blades 104 generates suction force. Correspondingly, during the rotation of the rotating shaft 103, two cleaning blocks 106 will rotate, and the cleaning blocks 106 will drive two circular rotating rods 113 to rotate. When the circular rotating rods 113 contact the triangular block 114, the inclined surface of the triangular block 114 will cause the triangular block 114 to move away from each other. The triangular block 114 will then cause the two closing plates 111 to move away from each other. At this time, the limit spring 110 will undergo compression deformation, closing. Plate 111 slides into rectangular groove 109. At this time, circular groove 107 opens, and suction force draws outside air into simulation device 1. Dust is filtered down by ventilation hole 105. During rotation, cleaning block 106 cleans the dust accumulated on ventilation hole 105 and discharges it from dust discharge groove 108. When the device stops running, cleaning block 106 stops rotating, and corresponding limit spring 110 will drive closing plate 111 to close under elastic force. At this time, strip sealing plate 2 will re-enter strip sealing groove 201, thereby improving the sealing performance of the device and effectively preventing dust from entering the device and affecting its operation.

[0029] The sealing mechanism includes several limiting springs 110 fixedly installed on the inner walls of two rectangular slides 109 on opposite sides. Two closing plates 111 are fixedly installed at the ends of the limiting springs 110 that are close to each other, and the two closing plates 111 are in contact. A strip-shaped sealing plate 2 is fixedly installed on the corresponding closing plate 111, and a strip-shaped sealing groove 201 is formed on the corresponding closing plate 111. The strip-shaped sealing plate 2 extends into the strip-shaped sealing groove 201 and slides within it. A rectangular box 202 is fixedly installed on the inner wall of the back of the simulation device 1. A T-shaped hollow slide plate 203 is slidably installed inside the rectangular box 202. A return spring 204 is fixedly installed on the inner wall of the back of the T-shaped hollow slide plate 203, and the front end of the return spring 204 is fixedly connected to the rectangular box 202. Strip-shaped exhaust ducts 205 are formed at the top and bottom of the T-shaped hollow slide plate 203, and several air inlet ducts 206 are formed at the bottom of the rectangular box 202.

[0030] After air enters the simulation device 1, the air pressure inside the simulation device 1 will increase. At this time, the air will enter the rectangular box 202 from the air inlet slot 206. The air will push the T-shaped hollow slide plate 203 to move away from the rectangular box 202. At this time, the return spring 204 will be stretched and deformed. When the T-shaped hollow slide plate 203 drives the strip exhaust slot 205 away from the simulation device 1, the air in the rectangular box 202 will be discharged from the strip exhaust slot 205. At this time, the depressurization and heat dissipation of the gas in the simulation device 1 are completed. When heat dissipation stops, the return spring 204 will drive the T-shaped hollow slide plate 203 to enter the rectangular box 202 again under the action of elasticity. At this time, the exhaust port of the device forms a seal, further improving the sealing performance of the device.

[0031] The working principle of the multifunctional power distribution network line simulation device provided by this utility model is as follows:

[0032] When in use, the drive motor 102 is started, which drives the rotating shaft 103 to rotate. The rotating shaft 103 drives several cooling fan blades 104 to rotate, and the rotation of the cooling fan blades 104 generates suction force. Correspondingly, during the rotation of the rotating shaft 103, two cleaning blocks 106 will rotate, and the cleaning blocks 106 will drive two circular rotating rods 113 to rotate. When the circular rotating rods 113 contact the triangular block 114, the inclined surface of the triangular block 114 will cause the triangular block 114 to move away from each other. The triangular block 114 will then cause the two closing plates 111 to move away from each other. At this time, the limit spring 110 will undergo compression deformation, closing. Plate 111 will slide into rectangular groove 109. At this time, circular groove 107 opens, and suction will draw outside air into simulation device 1. Dust will be filtered down by ventilation hole 105. During the rotation of cleaning block 106, the dust accumulated on ventilation hole 105 will be cleaned off and discharged from dust discharge groove 108. When the device stops running, cleaning block 106 stops rotating, and corresponding limit spring 110 will drive closing plate 111 to close under the action of elasticity. At this time, strip sealing plate 2 will re-enter strip sealing groove 201, thereby improving the sealing performance of the device and effectively preventing dust from entering the device and affecting its operation.

[0033] After air enters the simulation device 1, the air pressure inside the simulation device 1 will increase. At this time, the air will enter the rectangular box 202 from the air inlet slot 206. The air will push the T-shaped hollow slide plate 203 to move away from the rectangular box 202. At this time, the return spring 204 will be stretched and deformed. When the T-shaped hollow slide plate 203 drives the strip exhaust slot 205 away from the simulation device 1, the air in the rectangular box 202 will be discharged from the strip exhaust slot 205. At this time, the depressurization and heat dissipation of the gas in the simulation device 1 are completed. When heat dissipation stops, the return spring 204 will drive the T-shaped hollow slide plate 203 to enter the rectangular box 202 again under the action of elasticity. At this time, the exhaust port of the device forms a seal, further improving the sealing performance of the device.
