[0027] 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.

[0028] like Figures 1 to 7 As shown;

[0029] A locking device for the outer door of a wind power substation includes a door frame 1, and a door body 2 is provided inside the door frame 1.

[0030] In this implementation plan: According to the public announcement (CN212359420U), a locking device for the outer door of a wind power substation is disclosed. Although this design has the technical effect of preventing the door from closing due to strong winds, the door body 2 is not firmly fixed by only inserting the rubber head at the end of the top door rod into the positioning hole. In strong winds, the top door rod is prone to detach from the door body 2. Although the door body 2 can be prevented from closing under the action of the stop bar, the door body 2 is prone to continuous impact with the stop bar under strong winds, which can easily cause damage to the door body 2. To solve this technical problem, a locking component 3 and an auxiliary component 4 are added on this basis.

[0031] Furthermore:

[0032] Based on the above: The surface of the door frame 1 is provided with a locking assembly 3, which includes a gear 33 disposed inside the door frame 1 and an insert plate 36 disposed on the surface of the gear 33. A toothed block 310 is fixedly connected to an arc-shaped groove opened at one end of the insert plate 36 near the gear 33. A rectangular plate 38 is fixedly connected to the other end of the insert plate 36. A spring 37 is fixedly connected to the side of the rectangular plate 38 away from the insert plate 36. Two symmetrically arranged rotating shafts 32 are fixedly connected to the surface of the door body 2. The rotating shafts 32 are inserted into a rotating hole 31 opened inside the door frame 1. The rotating shafts 32 and the door frame 1 are rotatably connected. A clearance groove 311 is opened inside the door frame 1. The rectangular plate 38 is inserted into a third rectangular groove 39 opened on the surface of the door frame 1. The third rectangular groove 39, the first rectangular groove 34 and the second rectangular groove 35 are connected. The spring 37 is located inside the third rectangular groove 39, and the end of the spring 37 away from the rectangular plate 38 is fixedly connected to the door frame 1.

[0033] In this implementation: pulling the rectangular plate 38 causes it to compress the spring 37. The movement of the rectangular plate 38 moves the insert plate 36, which in turn causes the teeth on the toothed block 310 and gear 33 to disengage. At this time, the door 2 can rotate inside the door frame 1 under the action of the two rotating shafts 32, rotating until... Figure 1 At the position shown, the force applied to the rectangular plate 38 is released. Under the action of the elastic potential energy of the spring 37, the toothed block 310 on one side of the insert plate 36 can be inserted between the adjacent teeth on the surface of the gear 33, thereby fixing the position of the door body 2 after rotation. Moreover, under the action of the relief groove 311, it will not hinder the rotation of the door body 2 around the rotation axis 32, ensuring the effectiveness of the device. The depth of the relief groove 311 allows the door body 2 to rotate only 90 degrees. When the door body 2 is completely rotated into the door frame 1, the limited depth of the relief groove 311 can still ensure the gap between the door body 2 and the door frame 1, thereby ensuring the effectiveness of the device.

[0034] Furthermore:

[0035] In an optional embodiment, the gear 33 is disposed in a first rectangular groove 34 opened on the upper surface of the door frame 1, and one end of the gear 33 is fixedly connected to one of the rotating shafts 32. The insert plate 36 is inserted into a second rectangular groove 35 opened on the upper surface of the door frame 1, and the insert plate 36 is slidably connected to the door frame 1. A top cover 312 is disposed inside the first rectangular groove 34 and the second rectangular groove 35, and the top cover 312 is fixedly connected to the door frame 1.

[0036] In this embodiment: the first rectangular groove 34 and the second rectangular groove 35 opened on the upper surface of the door frame 1 facilitate the placement of the insert plate 36 and the gear 33, and the setting of the top cover 312 further enables the insert plate 36 and the gear 33 to be placed in the space formed by the top cover 312 and the door frame 1.

[0037] Furthermore:

[0038] In an optional embodiment, an auxiliary component 4 is provided on the surface of the door frame 1. The auxiliary component 4 includes a square plate 42, a rectangular block 44, and a carrier plate 46. The square plate 42 is inserted into a recessed groove 41 on the surface of the rectangular plate 38. The square plate 42 is rotatably connected to the rectangular plate 38 by a pivot pin. The rectangular block 44 is fixedly connected to the front surface of the door frame 1. The carrier plate 46 is fixedly connected to the side of the rectangular block 44 near the rectangular plate 38. One end of the square plate 42 is in contact with the surface of the carrier plate 46. The square plate 42 is in contact with the surface of the door frame 1. The auxiliary component 4 also includes a stop shaft 45 and a handle 43. The handle 43 is fixedly connected to the surface of the square plate 42. The stop shaft 45 is fixedly connected to the surface of the door frame 1. The stop shaft 45 is located above the rectangular plate 38.

[0039] In this implementation scheme: when the door 2 is rotated open from inside the door frame 1, a force is applied to the handle 43, causing one end of the square plate 42 to rotate inside the recessed groove 41. When the surfaces of the square plate 42 and the stop shaft 45 are in contact, and as the force applied to the square plate 42 increases, the rectangular plate 38 slides inside the third rectangular groove 39, thereby achieving the effect of moving the insert plate 36 away from the gear 33. At this time, the door 2 can be rotated easily, making it convenient for the staff to open the door 2. After the door 2 is rotated to a suitable position, the square plate 42 is rotated in the opposite direction, and one end of the square plate 42 is placed on the surface of the carrier plate 46. At this time, the rectangular block 44 can block one end of the square plate 42, thereby limiting the position between the toothed block 310 and the gear 33, thus ensuring the firmness of the door 2 after it is opened, and avoiding the problem that the door 2 is not firmly fixed and is easily damaged under the action of strong wind.

[0040] Working principle: When equipment repair or maintenance is required, pulling the rectangular plate 38 causes it to compress the spring 37. The movement of the rectangular plate 38 drives the insert plate 36 to move, which in turn causes the teeth on the surface of the toothed block 310 and gear 33 to disengage. At this time, the door 2 can rotate inside the door frame 1 under the action of the two rotating shafts 32, rotating until... Figure 1 At the position shown, the force applied to the rectangular plate 38 is released. Under the action of the elastic potential energy of the spring 37, the toothed block 310 on one side of the insert plate 36 can be inserted between the adjacent teeth on the surface of the gear 33, thereby fixing the position of the door body 2 after rotation. Moreover, under the action of the relief groove 311, it will not hinder the rotation of the door body 2 around the rotation axis 32, ensuring the effectiveness of the device.

[0041] With the auxiliary component 4, when the door 2 is rotated open from inside the door frame 1, a force is applied to the handle 43, causing one end of the square plate 42 to rotate inside the recessed groove 41. When the surface of the square plate 42 and the stop shaft 45 are in contact, and as the force applied to the square plate 42 increases, the rectangular plate 38 slides inside the third rectangular groove 39, thereby achieving the effect of moving the insert plate 36 away from the gear 33. At this time, the door 2 can be rotated easily, making it convenient for staff to open the door 2. After the door 2 is rotated to the appropriate position, the square plate 42 rotates in the opposite direction, and one end of the square plate 42 is placed on the surface of the carrier plate 46. At this time, the rectangular block 44 can block one end of the square plate 42, thereby limiting the position between the toothed block 310 and the gear 33, thus ensuring the firmness of the door 2 after it is opened, and avoiding the problem that the door 2 is not firmly fixed and is easily damaged under strong winds.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
