Description

Technical Field

[0001] The present application relates to the technical field of substations, and in particular to a buckle device. Background Art

[0002] The outdoor boxes of the substation mainly include terminal boxes, mechanism boxes, and control boxes, which are mainly used to store secondary components such as air switches, terminal blocks, motors, and SF6 relays. They are the hubs connecting primary and secondary equipment. Once damp, the secondary components in the box will be corroded, reducing the insulation performance of the secondary circuit. In severe cases, the secondary circuit will be grounded or short-circuited, causing electrical equipment to malfunction or refuse to operate. According to the "Guangzhou Power Supply Bureau Substation Wind and Flood Prevention Special Patrol (Before Typhoons and Heavy Rains) Operation Guide", before wind and flood prevention, all outdoor boxes in the substation need to be inspected to ensure that all box doors are reliably closed and there are no empty spaces when pushed by hand.

[0003] As the outdoor boxes in the substation are exposed to rain and sun for a long time, their doors are corroded and damaged to a certain extent and cannot be completely closed. During typhoons, it is easy for the boxes to crack or even open due to strong winds. Currently, iron wire or tape is usually used to reinforce the box doors, which is labor-intensive, cannot be reused, and takes time to clean up later. Summary of the invention

[0004] Based on this, it is necessary to provide a snap-on device to solve the problem that the outdoor box door in the substation is damaged and cannot be completely closed, especially when typhoons and rainstorms come, the box door needs to be closed to prevent internal components from getting damp.

[0056] See also Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a buckle device 1 provided in an embodiment of the present application includes a housing 11, a clamping assembly 12 and a first ratchet mechanism 13. The clamping assembly 12 is disposed on the housing 11, and includes a first clamping portion 121 and a second clamping portion 122; the first ratchet mechanism 13 is connected to the first clamping portion 121; the first clamping portion 121 is used to move relative to the first ratchet mechanism 13, and cooperate with the second clamping portion 122 to clamp or release the box.

[0057] First of all, it should be noted that the box described above can be an electrical box and cabinet in a substation, or other boxes and cabinets in a substation, or boxes and cabinets in other scenarios, that is, this application does not limit the specific type of the box. The box in this application refers to an electrical box and cabinet in a substation by way of example, and the type of the box will not be described in detail here.

[0058] Furthermore, the housing 11 serves as an external frame structure of the clamping assembly 12 and the first ratchet mechanism 13, and is used to support the clamping assembly 12 and the first ratchet mechanism 13. The clamping assembly 12 serves as a clamping structure of the buckle device 1, and is used to clamp or release the box. It should be noted that the first ratchet mechanism 13 is used to convert continuous rotation or reciprocating motion into unidirectional stepping motion.

[0059] Specifically, see Figure 5 and Figure 6 As shown, the first ratchet mechanism 13 is connected to the first clamping portion 121, and the first clamping portion 121 is used to move relative to the first ratchet mechanism 13, and cooperate with the second clamping portion 122 to clamp or release the box. The first ratchet mechanism 13 includes a first state and a second state; in the first state, the first clamping portion 121 moves in a direction away from the second clamping portion 122; in the second state, the first clamping portion 121 moves in a direction close to the second clamping portion 122.

[0060] When the box door of the box body is damaged and cannot be completely closed, at this time, the first ratchet mechanism 13 is adjusted to the first state, and the first clamping part 121 is controlled to move in a direction away from the second clamping part 122, so that the distance between the first clamping part 121 and the second clamping part 122 is greater than the size of the part of the box body that needs to be sealed, and the second clamping part 122 is clamped to one of the side surfaces of the box body. Further, the first ratchet mechanism 13 is adjusted to the second state, at this time, the first clamping part 121 is controlled to move in a direction close to the second clamping part 122, so that the first clamping part 121 is clamped to the other side surface of the box body, and then cooperates with the second clamping part 122 to clamp the box body.

[0061] On the contrary, when the box door needs to be loosened, the first ratchet mechanism 13 is adjusted to the first state, and the first clamping part 121 is controlled to move in a direction away from the second clamping part 122, so that the box is separated from the clamping action of the first clamping part 121 and the second clamping part 122, thereby loosening the box.

[0062] Since it is only necessary to control the different states of the first ratchet mechanism 13, the relative distance between the first clamping portion 121 and the second clamping portion 122 can be changed. When the box needs to be clamped, the first clamping portion 121 and the second clamping portion 122 are controlled to be close to each other until the first clamping portion 121 and the second clamping portion 122 clamp the box door. It can be understood that as long as the distance between the first clamping portion 121 and the second clamping portion 122 is greater than the size between the two sides of the box door that needs to be buckled, any type of box door can be clamped and buckled, which is highly practical and can promptly and effectively repair the box door that needs to be repaired, and can promptly and effectively solve the pain point of the box door being opened and damp under harsh conditions such as typhoons and rainstorms.

[0063] It should be noted that when the box door is damaged and cannot be completely closed, when the box door cannot be repaired in time, especially when it is in a typhoon or rainstorm, the first clamping part 121 can cooperate with the second clamping part 122 to clamp the box and close the box door, which can prevent the components inside the box from being damaged by moisture during a typhoon or rainstorm, and can reduce the workload of closing the box door, which is easy to operate. At the same time, as long as the distance between the first clamping part 121 and the second clamping part 122 is greater than the size between the two sides of the box that need to be fastened, any type of box door can be clamped and fastened, which is highly practical and can promptly and effectively repair the box door that needs to be repaired.

[0064] When the climate is normal, the first clamping part 121 can cooperate with the second clamping part 122 to loosen the box door, thereby realizing the maintenance of the box door, and at the same time, it is convenient to repair the box door. In addition, after the first clamping part 121 cooperates with the second clamping part 122 to loosen the box door, other box doors that need to be closed can be clamped, so that the buckle device 1 of the present application can be reused. It can be understood that, since the buckle device 1 of the present application only needs to move the first clamping part 121 away from the second clamping part 122 during the process of loosening the box door, the box door can be loosened, which reduces the time for later cleaning and facilitates the operation of the operator.

[0065] At the same time, since the distance between the first clamping part 121 and the second clamping part 122 is adjusted, the box doors of different sizes and types can be clamped, and the box doors of different sizes and types can be adapted, so that the maintenance of box doors of different models can be facilitated. In particular, in severe conditions such as typhoons and rainstorms, it is not necessary to select according to the model of the box, and it is only necessary to control the relative movement between the first clamping part 121 and the second clamping part 122, so that the first clamping part 121 cooperates with the second clamping part 122 to clamp the box door, so as to achieve the buckling and sealing of the box door, and the box door can be repaired in time, which improves the convenience of maintenance in severe conditions.

[0066] In addition, when the snap-fit ​​device 1 of the present application is not needed, the first ratchet mechanism 13 only needs to be switched to the first state, so that the first clamping portion 121 can be moved away from the second clamping portion 122, thereby loosening the box door, simplifying the operator's disassembly steps and facilitating the operator's operation.

[0067] In addition, when the box body or door on which the snap device 1 has been installed no longer needs the snap device 1, it is only necessary to remove the snap device 1, and the snap device 1 can still be applied to other box bodies or doors as needed, thereby improving the recycling of the snap device 1 and saving the production cost of the snap device 1.

[0068] It can be understood that since the snap-in device 1 of the present application can snap-close the open box door that needs maintenance in time under severe conditions such as typhoons and rainstorms, it can avoid abnormal damage to equipment such as box doors during a normal cycle, extend the service life of equipment such as box doors, and have high economic value.

[0069] It should be noted that, for the box door of the substation, under the influence of severe conditions such as typhoons and rainstorms, when the sealing effect of the box door is reduced and it is opened due to the influence of wind and rain, it will cause damage to the electrical components inside the box, thereby affecting the normal power supply. Since the snap-fit ​​device 1 of the present application can close the sealed box in time, it can reduce the possibility of malfunction of electrical components inside the box and reduce the occurrence of accidents such as power outages, thereby having higher social value.

[0070] In one embodiment, see Figure 5 , Figure 6 and Figure 7 As shown, the first clamping portion 121 is provided with a rack 1211; the first ratchet mechanism 13 includes a ratchet 131 and a pawl 132: see Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the ratchet 131 is meshed and connected to the rack 1211; the pawl 132 is used to mesh and connect with the ratchet 131, and one of the first meshing portion 1322 and the second meshing portion 1323 is connected to the ratchet 131, so that the first ratchet mechanism 13 switches between the first state and the second state. In the first state, the ratchet 131 is used to rotate relative to the pawl 132 in a first direction; in the second state, the ratchet 131 is used to rotate relative to the pawl 132 in a second direction; the first direction is opposite to the second direction.

[0071] In this way, when it is necessary to control the first clamping portion 121 to move in a direction away from the second clamping portion 122, it is only necessary to switch the first ratchet mechanism 13 to the first state. At this time, the ratchet 131 rotates relative to the pawl 132 in the first direction and cannot rotate in the second direction, thereby enabling the first clamping portion 121 to move in a direction away from the second clamping portion 122. Conversely, when it is necessary to control the first clamping portion 121 to move in a direction close to the second clamping portion 122, it is only necessary to switch the first ratchet mechanism 13 to the second state. At this time, the ratchet 131 rotates relative to the pawl 132 in the second direction and cannot rotate in the first direction, thereby enabling the first clamping portion 121 to move in a direction close to the second clamping portion 122.

[0072] Since the present application only needs to control the first clamping member to move in a specific direction relative to the second clamping member through different movement modes of the ratchet 131 relative to the pawl 132, on the one hand, the clamping and loosening of the box door can be realized, so that the maintenance of the box door can be facilitated. On the other hand, the operation of the buckle device 1 can be facilitated, simplifying the operation difficulty of the operator.

[0073] In one embodiment, see Figure 5 , Figure 6 and Figure 7 As shown, the pawl 132 includes a pawl body 1321, a first meshing portion 1322 and a second meshing portion 1323. The first meshing portion 1322 is provided on one side of the pawl body 1321; the second meshing portion 1323 is provided on the other side of the pawl body 1321. In the first state, the first meshing portion 1322 is meshed and connected to the ratchet 131, and the second meshing portion 1323 is separated from the ratchet 131; in the second state, the second meshing portion 1323 is meshed and connected to the ratchet 131, and the first meshing portion 1322 is separated from the ratchet 131.

[0074] In this way, since in the first state, the first meshing portion 1322 is meshed and connected to the ratchet 131, and the second meshing portion 1323 is separated from the ratchet 131; in the second state, the second meshing portion 1323 is meshed and connected to the ratchet 131, and the first meshing portion 1322 is separated from the ratchet 131, the different positional relationships between the first meshing portion 1322 and the second meshing portion 1323 relative to the ratchet 131 can be used to control the different movement states of the pawl 132 relative to the ratchet 131, thereby simplifying the design difficulty of the snap device 1 and improving the convenience of operating the snap device 1.

[0075] In one embodiment, see Figure 3 As shown, the first ratchet mechanism 13 further includes a toggle member 133. The toggle member 133 is connected to the ratchet 131 body, and is used to toggle the ratchet 131 body to drive the first meshing portion 1322 and the second meshing portion 1323 to switch between the first state and the second state.

[0076] In this way, the different positional relationships of the first meshing portion 1322 and the second meshing portion 1323 relative to the ratchet 131 can be controlled by the toggle member 133 , thereby facilitating the operation of the operator.

[0077] In one embodiment, see Figure 3 and Figure 8 As shown, the housing 11 is provided with a through hole; a locking portion 1311 is provided on one side of the ratchet 131, and the locking portion 1311 passes through the through hole.

[0078] In this way, in the process of clamping the box door through the first clamping part 121 and the second clamping part 122, when the distance between the first clamping part 121 and the second clamping part 122 is gradually shortened until it works together with the second clamping part 122 to clamp the box door, by locking the locking part 1311, since the locking part 1311 is penetrated through the through hole, and the through hole is arranged on one side of the ratchet 131, the ratchet 131 can be locked by locking the locking part 1311, thereby ensuring that the ratchet 131 and the pawl 132 are in a relatively static state, and then the ratchet 131 can be prevented from moving relative to the pawl 132, thereby ensuring the reliability of the first clamping part 121 and the second clamping part 122 clamping the box.

[0079] In one embodiment, the first clamping portion 121 defines a notch 1212 , the rack 1211 is disposed on an inner sidewall of the notch 1212 , and the first ratchet mechanism 13 is disposed in the notch 1212 .

[0080] In this way, since the rack 1211 is arranged on the inner wall of the slot 1212 and the first ratchet mechanism 13 is arranged in the slot 1212, on the one hand, the space occupied by the rack 1211 on the first clamping portion 121 can be saved, thereby improving the space utilization rate of the first clamping portion 121; on the other hand, the space occupied by the first ratchet mechanism 13 can be saved, thereby improving the space utilization rate of the first ratchet mechanism 13, and further improving the space utilization rate of the buckle device 1.

[0081] In one embodiment, see Figure 4 As shown, the first clamping portion 121 includes a first connecting member 1213 and a first bending member 1214, and the first connecting member 1213 is connected to the shell 11 and the first bending member 1214; the second clamping portion 122 includes a second connecting member 1221 and a second bending member 1222, and the second connecting member 1221 is connected to the shell 11 and the second bending member 1222; the first bending member 1214 and the second bending member 1222 are used to clamp the box or loosen the box.

[0082] In this way, the first connecting member 1213 and the first bending member 1214 can be respectively clamped on two different side surfaces on one side of the box, and at the same time, the second connecting member 1221 and the second bending member 1222 can be respectively clamped on different side surfaces on the other side of the box, so that the four side surfaces of the box can be clamped by the clamping device 1, thereby improving the clamping reliability of the clamping device 1 to the box.

[0083] In one embodiment, the first clamping portion 121 also includes a first anti-slip member, which is disposed on the side of the first bending member 1214 facing the second bending member 1222; the second clamping portion 122 also includes a second anti-slip member, which is disposed on the side of the second bending member 1222 facing the first bending member 1214.

[0084] In this way, since the first anti-slip part is arranged on the side of the first bending part 1214 facing the second bending part 1222, and the second anti-slip part is arranged on the side of the second bending part 1222 facing the first bending part 1214, the first anti-slip part can be used to increase the abutment force of the clamping connection between the first bending part 1214 and the box body, and at the same time, the second anti-slip part can be used to increase the abutment force of the clamping connection between the second bending part 1222 and the box body, so that the clamping reliability of the snap device 1 on the box door can be further improved through the first anti-slip part and the second anti-slip part.

[0085] In one embodiment, the snap-fit ​​device 1 also includes a second ratchet mechanism connected to the second clamping portion 122; the second clamping portion 122 is used to move relative to the second ratchet mechanism to cooperate with the first clamping portion 121 to clamp or release the box body; in the first state, the second clamping portion 122 moves in a direction away from the first clamping portion 121; in the second state, the second clamping portion 122 moves in a direction close to the first clamping portion 121.

[0086] In this way, the first ratchet mechanism 13 and the second ratchet mechanism can work together to synchronously or asynchronously adjust the relative position between the first clamping portion 121 and the second clamping portion 122, thereby achieving the locking or releasing of the box door, which can facilitate the maintenance of the box.

[0087] In addition, since the first ratchet mechanism 13 and the second ratchet mechanism can both move relative to each other, the force applied to the first ratchet mechanism 13 during movement can be balanced by the second ratchet mechanism, thereby increasing the service life of the first ratchet mechanism 13 and further increasing the service life of the buckle device 1 as a whole.

[0088] In addition, if the first ratchet mechanism 13 fails and cannot move normally, the second ratchet mechanism can cooperate with the first ratchet mechanism 13 to achieve the locking or releasing of the box door, thereby ensuring the normal operation of the operator.

[0089] In one embodiment, the housing 11 is provided with a groove, and at least one of the first clamping portion 121 and the second clamping portion 122 is disposed in the groove.

[0090] Thus, on the one hand, since at least one of the first clamping portion 121 and the second clamping portion 122 is disposed in the groove, the space occupied by the first clamping portion 121 and the second clamping portion 122 can be reduced, thereby improving the space utilization of the first clamping portion 121 and the second clamping portion 122, and further improving the overall space utilization of the buckle device 1. On the other hand, since the first clamping portion 121 and the second clamping portion 122 are disposed in the groove, the first clamping portion 121 and the second clamping portion 122 can be protected by the housing 11, thereby improving the service life of the buckle device 1.

[0091] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
