Description

Technical Field

[0001] The present invention relates to the technical field of relays, and in particular to a fast-acting oil pressure relay. Background Art

[0002] The fast-acting oil pressure relay is a new type of transformer oil tank pressure relay protection device. The faster the oil pressure increases, the faster the action. Since the oil pressure wave propagates very quickly in the transformer oil, the fast-acting oil pressure relay is sensitive and precise in action. It can quickly send out signals and cut off the power supply. If a fast-acting oil pressure relay is installed on the transformer, once a malignant short circuit occurs inside, it can prevent the oil tank from exploding.

[0003] When existing fast-acting oil pressure relays are inspected and installed, the inspection work is usually carried out by one operator alone, and the operator needs to hold tools and continuously support the relay, which is inconvenient for the operator to operate and has low inspection efficiency. Since the relays that need to be replaced are mostly damaged, when the relays are dismantled and replaced, broken pieces and surface dust and other materials are easy to fall into the transformer tank, which can easily contaminate the oil. At the same time, it can also protect the inside of the transformer tank. Therefore, the present application provides a fast-acting oil pressure relay to meet the needs. Summary of the invention

[0038] like Figures 1 to 9 As shown, an embodiment of the present invention provides a fast-acting oil pressure relay, including a relay 1, wherein a refueling port 2 is provided at the bottom end of the relay 1, a shell 3 is provided on the outer side of the bottom end of the refueling port 2, the bottom end of the shell 3 is connected to a transformer oil port 4, the bottom end of the transformer oil port 4 is connected to a transformer 8, and further includes a fixing component 5, the fixing component 5 is installed on the inner side of the shell 3, the fixing component 5 is located on the outer side of the transformer oil port 4, the fixing component 5 is used for auxiliary fixing, a clamping component 6, the clamping component 6 is installed above the fixing component 5, the clamping component 6 is used to clamp the oil tank cover, and a switching component 7, the switching component 7 is installed on the inner side of the shell 3, and the switching component 7 is used to switch the channel opening and closing state.

[0039] like Figures 1 to 4 As shown, the fixing assembly 5 includes a mounting plate 51, and five rotating rods 52 are installed at equal angles on the bottom end of the mounting plate 51, and a rotating plate 53 is installed on the outer side of each rotating rod 52. A sealing gasket 54 is connected to the end of each rotating plate 53, and a connecting rod 55 is connected to one side of each rotating plate 53. A gear ring 56 is connected between the tail ends of each connecting rod 55, and the gear ring 56 is installed on the bottom end of the mounting plate 51. The gear ring 56 rotates at the bottom end of the mounting plate 51, and a sealing sleeve 57 is connected to the bottom end of the gear ring 56. The sealing sleeve 57 is nested and installed on the inner side of the housing 3, and the gear ring 56 is meshed with a gear 58. The gear 58 rotates on the outer bracket of the sealing sleeve 57, and the end of the gear 58 is connected to a bevel gear set 59, and the output end of a bevel gear in the bevel gear set 59 is connected to a quick-release rocker 510.

[0040] By setting the fixing component 5, the operator first places the relay 1 at a position close to the transformer 8, aligns the positions of the oil filling port 2 and the transformer oil port 4, the operator supports the housing 3 with one hand, inserts the quick-release rocker 510, and manually rotates the quick-release rocker 510 first. The quick-release rocker 510 drives the bevel gear set 59 to rotate, and the bevel gear set 59 drives the gear 58 to rotate by mutual engagement. The gear 58 rotates on the outer bracket of the sealing sleeve 57, and the gear 58 is engaged with the gear ring 56. The gear ring 56 rotates at the bottom end of the mounting plate 51, and the gear ring 56 drives the connecting rod 55 to rotate. The connecting rod 55 pulls the rotating plate 53, so that the rotating rod 52 at the bottom end of the mounting plate 51 drives the corresponding rotating plate 53 to rotate, so that the connecting hole of the sealing sleeve 57 is opened, and the operator partially covers the sealing sleeve 57 on the outside of the transformer oil port 4. The operator rotates the quick-release rocker 510 in the opposite direction to make the quick-release rocker 510 rotate. 510 drives bevel gear set 1 59 to mesh and rotate, and a bevel gear in bevel gear set 1 59 drives gear 58 to rotate, and gear 58 meshes with gear ring 56 to drive gear ring 56 to rotate counterclockwise at the end of mounting plate 51, so that gear ring 56 pushes five connecting rods 55, so that connecting rod 55 pushes corresponding rotating plate 53 to rotate toward the outside of transformer oil port 4 with rotating rod 52 as rotating axis. When the operator feels resistance when shaking quick-release rocker 1 510, stop shaking quick-release rocker 1 510 and pull out quick-release rocker 1 510. At this time, sealing gasket 54 contacts the outer side wall of transformer oil port 4, so that the position between relay 1 and transformer 8 can be relatively fixed, and the operator no longer needs to continuously support relay 1 during installation, which is convenient for the operator to install. At the same time, it can be applicable to transformer oil ports 4 of different sizes, thereby improving the versatility of the device and avoiding the limitation of only being applicable to a single type of transformer 8.

[0041] like Figures 5 to 8 As shown, the clamping assembly 6 includes a mounting box 61, which is nested and installed on the inner side of the shell 3. A mounting ring 62 is installed on the inner side of the mounting box 61. Four bevel gears 63 are installed at equal angles on the outer side of the mounting ring 62. Each bevel gear 63 rotates on the outer bracket of the mounting ring 62. A screw 64 is connected to the output end of each bevel gear 63. The outer thread of each screw 64 is meshed with a threaded sleeve 65. Each threaded sleeve 65 slides on the inner side of the mounting ring 62 respectively. A clamping block 66 is connected to the end of the threaded sleeve 65. A bevel gear disk 67 is installed on the outer side of the mounting ring 62. The bevel gear disk 67 is meshed with the four bevel gears 63 respectively. The bevel gear disk 67 rotates on the outer side of the mounting ring 62. A quick-release rocker lever 2 68 is connected to the end of one bevel gear 63. The quick-release rocker lever 2 68 runs through the side wall of the mounting box 61. Two limit rods 69 are symmetrically nested and installed on the inner side of the mounting box 61.

[0042] By setting the clamping assembly 6, the operator then manually rotates the quick-release rocker lever 68 to rotate the bevel gear 63 connected to the quick-release rocker lever 68. The bevel gear 63 meshes with the bevel gear plate 67, and the bevel gear plate 67 rotates on the outside of the mounting ring 62 and meshes with the other three bevel gears 63. When the four bevel gears 63 rotate, the screws 64 connected to the tail ends of the four bevel gears 63 rotate. The screws 64 mesh with the threaded sleeves 65, so that the four threaded sleeves 65 drive the corresponding clamping blocks 66 to the center of the mounting ring 62. The axis moves so that the four clamping blocks 66 clamp the oil tank cap of the transformer 8 at the same time. When the operator feels resistance when manually rotating the quick-release rocker lever 2 68, the operator stops rotating the quick-release rocker lever 2 68 and pulls out the quick-release rocker lever 2 68. The operator rotates the limit rod 69 to remove the oil tank cap to prevent the oil tank cap from causing surface dust to fall into the oil tank. The oil tank cap can be clamped in different sizes, which is convenient for the operator to operate. When the oil tank cap thread is stuck, the operator does not need to use special tools to remove it, thereby improving the operator's operating efficiency.

[0043] like Figure 2 and Fig. 9 As shown, the switching assembly 7 includes a fixed box 71, which is installed on the inner side of the shell 3, and the bottom end of the fixed box 71 is connected to a fixed plate 72, and a connecting hole 73 is provided on the inner side of the fixed plate 72. A transmission rod 74 is nested on the inner side of the fixed plate 72, and a rotating plate 75 is connected to the bottom end of the transmission rod 74, and a connecting hole 76 is provided on the inner side of the rotating plate 75. The top end of the transmission rod 74 is connected to a bevel gear set 77, and the input end of a bevel gear in the bevel gear set 77 is connected to a handle 78, and the handle 78 is arranged on the outer side of the shell 3 in a through-type manner.

[0044] By setting the switching assembly 7, when replacing the relay 1, the housing 3 and the refueling port 2 are removed and separated, and then the operator replaces it, so that when replacing the relay 1, impurities on the surface of the relay 1 will not fall into the oil tank of the transformer 8, thereby avoiding pollution to the inside of the oil tank. The operator rotates the handle 78 to drive the bevel gear set 2 77 to rotate, and the bevel gear set 2 77 meshes and rotates with each other. A bevel gear in the bevel gear set 2 77 drives the transmission rod 74 to rotate, so that the rotating plate 75 rotates with the transmission rod 74, so that the connecting hole 2 76 is aligned with the connecting hole 1 73 on the inner side of the fixed plate 72 through the rotation of the rotating plate 75, so that the oil circuit can be normally connected, and the fixed box 71 can avoid the bevel gear set 2 77 from affecting the oil circuit. By using the handle 78 for transmission, the connecting hole 1 73 and the connecting hole 2 76 are staggered, and the transformer oil port 4 is blocked, so that when replacing the relay 1, impurities on the surface of the relay 1 will not fall into the oil tank of the transformer 8, thereby avoiding pollution to the inside of the oil tank.

[0045] The working principle of the technical solution provided by the present invention is as follows:

[0046] The operator first places the relay 1 near the transformer 8, aligns the oil filling port 2 and the transformer oil port 4, supports the housing 3 with one hand, inserts the quick-release rocker 510, and manually rotates the quick-release rocker 510 first. The quick-release rocker 510 drives the bevel gear set 59 to rotate, and the bevel gear set 59 drives the gear 58 to rotate by mutual meshing rotation. The gear 58 rotates on the outer bracket of the sealing sleeve 57, and the gear 58 meshes with the gear ring 56. The gear ring 56 rotates at the bottom end of the mounting plate 51, and the gear ring 56 drives the connecting rod 55 to rotate. The connecting rod 55 pulls the rotating plate 53 to make the rotating rod 52 at the bottom end of the mounting plate 51 drive the corresponding rotating plate 53 to rotate, so that the connecting hole of the sealing sleeve 57 is opened, and the operator partially covers the sealing sleeve 57 on the outside of the transformer oil port 4. The operator rotates the quick-release rocker 510 in the opposite direction to make the quick-release rocker 510 drive the The movable bevel gear set 59 meshes and rotates, and a bevel gear in the bevel gear set 59 drives the gear 58 to rotate. The gear 58 meshes with the gear ring 56, driving the gear ring 56 to rotate counterclockwise at the end of the mounting plate 51, so that the gear ring 56 pushes the five connecting rods 55, and the connecting rods 55 push the corresponding rotating plate 53 to rotate toward the outside of the transformer oil port 4 with the rotating rod 52 as the rotation axis. When the operator feels resistance when shaking the quick-release rocker 510, stop shaking the quick-release rocker 510 and pull out the quick-release rocker 510. At this time, the sealing gasket 54 contacts the outer side wall of the transformer oil port 4, so that the position between the relay 1 and the transformer 8 can be relatively fixed. The operator no longer needs to continuously support the relay 1 during installation, which is convenient for the operator to install. At the same time, it can be applicable to transformer oil ports 4 of different sizes, thereby improving the versatility of the device and avoiding the limitation of only being applicable to a single type of transformer 8.

[0047] Then the operator manually rotates the quick-release rocker lever 2 68 to rotate the bevel gear 63 connected to the quick-release rocker lever 2 68. The bevel gear 63 meshes with the bevel gear plate 67, and the bevel gear plate 67 rotates on the outside of the mounting ring 62 and meshes with the other three bevel gears 63. When the four bevel gears 63 rotate, the screw rod 64 connected to the tail ends of the four bevel gears 63 rotates. The screw rod 64 meshes with the threaded sleeve 65, so that the four threaded sleeves 65 drive the corresponding clamping blocks 66 to move toward the central axis of the mounting ring 62, so that the four clamping blocks 66 clamp the oil tank cap of the transformer 8 at the same time. When the operator feels resistance when manually rotating the quick-release rocker lever 2 68, he stops rotating the quick-release rocker lever 2 68 and pulls out the quick-release rocker lever 2 68. The operator rotates the limit rod 69 to remove the oil tank cap to prevent the oil tank cap from causing surface dust to fall into the oil tank.

[0048] When replacing relay 1, the housing 3 and the refueling port 2 are removed and separated, and then the operator replaces it to avoid that impurities on the surface of relay 1 will fall into the oil tank of transformer 8 during the replacement of relay 1, thereby avoiding pollution to the inside of the oil tank. The operator rotates the handle 78 to drive the bevel gear set 2 77 to rotate, and the bevel gear sets 2 77 mesh with each other and rotate. A bevel gear in the bevel gear set 2 77 drives the transmission rod 74 to rotate, so that the rotating plate 75 rotates with the transmission rod 74, so that the connecting hole 2 76 is aligned with the connecting hole 1 73 on the inner side of the fixed plate 72 through the rotation of the rotating plate 75, so that the oil circuit can be connected normally, and the fixed box 71 can prevent the bevel gear set 2 77 from affecting the oil circuit.

[0049] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
