Technical Field
[0001] The present disclosure relates to the technical field of protective covers for electric actuators, and more particularly, to a protective cover assembly for an electric actuator. Background Art
[0002] In the automatic control of power plants, the adjustment of electric actuators directly determines the quality of the adjustment of each system and the safety of the unit equipment. Therefore, corresponding requirements are imposed on the safety and reliability of the actuators. Each electric actuator has a local control panel, and the control panel has several forms such as knob type and button type. To prevent misoperation, a protective cover is installed outside the control panel. The existing protective cover is usually hinged to the electric actuator at the lower end, and the upper end of the protective cover is fixedly connected to the electric actuator by screws. During the overhaul and maintenance process, the screws of the protective cover often fall off due to vibration, so that the protective plate opens, and the knobs or buttons of the control panel are exposed, resulting in misoperation events easily occurring during the overhaul and maintenance process. Summary of the Utility Model
[0003] The purpose of the present disclosure is to provide a protective cover assembly for an electric actuator, which can stably cover the control panel of the electric actuator and avoid the problem of misoperation during the overhaul and maintenance process, so as to solve at least part of the problems in the related art.
[0004] To achieve the above purpose, the present disclosure provides a protective cover assembly for an electric actuator, including: a fixing plate for fixedly connecting with the housing of the electric actuator, an avoidance opening for avoiding the input end of the electric actuator is provided on the fixing plate, a cover plate, a hinge shaft for hinged connection with the fixing plate is provided at the upper end of the cover plate, and a shielding portion for shielding the input end of the electric actuator is provided at the lower end of the cover plate.
[0005] Optionally, guard plates protruding outward in the thickness direction of the fixing plate are respectively provided on both sides of the fixing plate in the width direction, and hinge holes for hinged cooperation with the hinge shaft are provided on both guard plates.
[0006] Optionally, connection holes are provided on both sides of the fixing plate in the width direction and inside the guard plates, and fasteners pass through the connection holes to fixedly connect the fixing plate with the housing of the electric actuator.
[0007] Optionally, the number of the connection holes is multiple and they are arranged at intervals along the length direction of the fixing plate.
[0008] Optionally, a limiting block protruding outward in the thickness direction of the fixing plate is provided on the fixing plate, the limiting block is located inside the guard plate, and the shielding portion abuts against the limiting block so as to form a gap between the shielding portion and the fixing plate.
[0009] Optionally, there are a plurality of the limiting blocks, and the limiting blocks are arranged at intervals along the outer periphery of the avoidance opening.
[0010] Optionally, in the length direction of the cover plate, the shielding portion extends to the outside of the fixing plate and forms a gripping end.
[0011] Optionally, an observation opening is further provided on the cover plate.
[0012] Optionally, a buffer block is further provided between the shielding portion and the fixing plate.
[0013] Optionally, a pressure monitoring mechanism is provided between the shielding portion and the fixing plate.

[0021] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0022] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, left, right", generally refer to the use state of the protective cover assembly of the electric actuator, and "inside, outside" refer to the outline of the part itself. In addition, it should be noted that the terms used, such as "first, second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.
[0023] like Figure 1 and Figure 2 As shown, the present disclosure provides a protective cover assembly of an electric actuator, comprising: a fixed plate 1 and a cover plate 2, both of which can be made of stainless steel plates, the fixed plate 1 is fixedly connected to the housing of the electric actuator, for example, the fixed plate 1 can be fixed to the housing of the electric actuator by screws, the fixed plate 1 is provided with a avoidance opening 11 for avoiding the input end of the electric actuator, so that the setting of the avoidance opening 11 can avoid the contact between the fixed plate 1 and the input end of the electric actuator, a hinge shaft 21 hingedly connected to the fixed plate 1 is provided at the upper end of the cover plate 2, and a shielding portion 22 for shielding the input end of the electric actuator is provided at the lower end of the cover plate 2, the upper end of the cover plate 2 is hingedly connected to the fixed plate 1 through the hinge shaft 21, so that the shielding portion 22 at the lower end of the cover plate 2 can shield the input end of the electric actuator.
[0024] Through the above technical solution, the protective cover assembly of the electric actuator includes a fixing plate 1 and a cover plate 2. The fixing plate 1 is fixedly connected to the housing of the electric actuator. The input end of the electric actuator is avoided through the avoidance opening 11. The upper end of the cover plate 2 is provided with a hinge shaft 21 and is hingedly connected to the fixing plate 1. The lower end of the cover plate 2 is provided with a shielding portion 22 that shields the input end of the electric actuator. By hingedly connecting the upper end of the cover plate 2 to the fixing plate 1, the cover plate 2 can naturally droop by its own weight, and the input end of the electric actuator can be shielded by the shielding portion 22 at the lower end of the cover plate 2. When adjustment is required, the cover plate 2 can be rotated relative to the fixing plate 1 through the hinge shaft 21 of the cover plate 2, and the input end of the electric actuator can be exposed, facilitating the staff to adjust the working condition of the electric actuator. Through the cooperation of the cover plate 2 and the fixing plate 1, it is possible to avoid the method in the related art of hingedly connecting the lower end of the cover plate to the electric actuator and fixedly connecting the upper end to the electric actuator through screws, thereby solving the problem in the related art that the protective cover falls off due to vibration during maintenance, resulting in no protection for the control panel and accidental operation of the equipment by cleaning staff and daily maintenance personnel, thus improving the overall safety of the electric actuator.
[0025] In some implementable ways, on both sides of the fixing plate 1 in the width direction, there are guard plates 12 protruding outward in the thickness direction of the fixing plate 1. Both guard plates 12 are provided with hinge holes 13 that are hingedly matched with the hinge shaft 21. The guard plates 12 can also be stainless steel plates. The two guard plates 12 extend along the length direction of the fixing plate 1. The two guard plates 12 can protect the cover plate 2 from the side direction, avoiding damage to the cover plate 2 due to lateral force. At the same time, corresponding hinge holes 13 are provided on the two guard plates 12, facilitating the insertion of the hinge shaft 21 on the cover plate 2 into the corresponding hinge holes 13, and facilitating the hinged connection between the cover plate 2 and the fixing plate 1. Among them, the length direction can refer to Figure 1 the direction pointed by X in Figure 1 and the thickness direction can refer to
[0026] It can be understood that the above-mentioned guard plates 12 can be independently provided and fixedly connected to the fixing plate 1 by welding. Of course, the guard plates 12 can also be integrally formed with the fixing plate 1. For example, the fixing plate 1 can be turned up to form the guard plates 12. In order to facilitate the overall hinged connection of the cover plate 2 relative to the fixing plate 1, the hinge holes 13 are at a certain distance from the fixing plate 1. In addition, in order to limit the rotation angle of the cover plate 2 relative to the fixing plate 1, a stop block can also be provided on the fixing plate 1. When the cover plate 2 is flipped, the outer side edge of the cover plate 2 abuts against the stop block, thereby limiting the flipping angle of the cover plate 2 and avoiding damage caused by excessive flipping angle of the cover plate 2 and collision between the shielding portion 22 and other components.
[0027] It can be understood that the above-mentioned hinge shaft 21 can be integrally formed with the cover plate 2 or fixedly welded to the cover plate 2. In this embodiment, asFigure 1 and Figure 2 As shown in Figure 2 , the hinge shaft 21 is integrally formed with the cover plate 2. Specifically, on the cover plate 2, the hinge shafts 21 disposed opposite to each other in the width direction of the cover plate 2 can be cut out on both sides of the upper end of the cover plate 2 by cutting. The hinge shaft 21 can be cylindrical or regular polygon. The extension length of the hinge shaft 21 passes through the hinge hole 13, so that there is a certain margin in the width direction of the cover plate 2, avoiding the separation of the cover plate 2 from the fixing plate 1 during the flipping process of the cover plate 2. Of course, in order to further avoid the separation of the cover plate 2 from the fixing plate 1 during the flipping process, positioning holes can be provided at the outer ends of the hinge shafts 21, and positioning pins can be inserted into the positioning holes, thereby preventing the cover plate 2 from separating from the fixing plate 1 in the width direction.
[0028] Of course, it can be understood that threaded holes can also be provided on both sides of the upper end of the cover plate 2. The hinge shaft 21 and the cover plate 2 are of split design. The side of the hinge shaft 21 facing the cover plate 2 is provided with external threads. The hinge shaft 21 is threadedly connected to the threaded holes on both sides of the upper end of the cover plate 2, so as to be hingedly connected to the fixing plate 1 through the hinge shaft 21, and thus it is convenient to adjust and replace the worn hinge shaft 21 in a detachable and split manner.
[0029] In some specific embodiments, connection holes 14 are provided on both sides of the fixing plate 1 in the width direction and inside the guard plate 12. Fasteners pass through the connection holes 14 to fixedly connect the fixing plate 1 with the housing of the electric actuator. Among them, the connection holes 14 can be through holes or threaded holes. Corresponding mating holes are provided on the housing of the electric actuator. The mating holes can be threaded holes. The fasteners can be screws. The screws pass through the connection holes and are threadedly connected to the mating holes, so as to be able to fixedly connect the fixing plate 1 with the housing of the electric actuator. In order to improve the connection strength between the fixing plate 1 and the housing of the electric actuator, in some feasible embodiments, the number of the connection holes 14 is multiple and they are arranged at intervals along the length direction of the fixing plate 1, so that the fixing plate 1 can be fixed on the housing of the electric actuator by multiple screws passing through the connection holes and being threadedly connected to the mating holes.
[0030] In some feasible embodiments, a limiting block 15 protruding outward in the thickness direction of the fixing plate 1 is provided on the fixing plate 1. The limiting block 15 is located inside the guard plate 12. The shielding portion 22 and the limiting block 15 are in contact with each other so as to form a gap between the shielding portion 22 and the fixing plate 1. Among them, the shape of the limiting block 15 can be strip-shaped or frame-shaped, such as Figure 2As shown, there are multiple limiting blocks 15, and the limiting blocks 15 are arranged at intervals along the outer periphery of the avoidance opening 11. The limiting blocks 15 include a strip-shaped limiting block 15 and two frame-shaped limiting blocks 15. The strip-shaped limiting block 15 is arranged at the lower end of the fixing plate 1, and the two frame-shaped limiting blocks 15 are respectively arranged in the middle of the shielding part 22 on the fixing plate 1, so that a safety gap can be formed between the shielding part 22 and the fixing plate 1 through the three limiting blocks 15.
[0031] In addition, in order to facilitate lifting the cover plate 2, in the length direction of the cover plate 2, the shielding part 22 extends to the outside of the fixing plate 1 and forms a holding end 24. In this way, when it is necessary to lift the cover plate 2, it can be done by holding the holding end 24 with the hand.
[0032] Of course, in order to facilitate real-time observation of the data of the electric actuator, in some implementable ways, an observation port 23 is also provided on the cover plate 2. The specific size of the observation port 23 needs to be determined according to the content displayed on the shell of the specific electric actuator, as long as it can meet the observation requirements.
[0033] In some implementable ways, in order to prevent the shielding part 22 from being damaged when the shielding part 22 is accidentally subjected to a load, in some implementable ways, a buffer block is also provided between the shielding part 22 and the fixing plate 1. The buffer block can be a rubber pad, and the number of buffer blocks can be multiple. The multiple buffer blocks are arranged at intervals along the outer periphery of the avoidance opening 11 on the fixing plate 1, so that the shielding part 22 accidentally subjected to a load has a certain buffer space, further improving the safety.
[0034] In order to facilitate, in some implementable ways, a pressure monitoring mechanism is provided between the shielding part 22 and the fixing plate 1. The pressure monitoring mechanism includes a controller, a pressure sensor and an alarm. Both the pressure sensor and the alarm are signal-connected to the controller. The pressure sensor is used to monitor the pressure between the shielding part 22 and the fixing plate 1 and transmit the pressure value to the controller. The controller controls the alarm to work according to the pressure value of the pressure sensor. For example, the controller can be a single-chip microcomputer, the pressure sensor can be a strain type pressure sensor, and the alarm can include a warning bell and a warning light. The pressure sensor monitors the pressure between the shielding part 22 and the fixing plate 1 in real time. When the pressure corresponding to the shielding part 22 obtained by the controller is too large, the single-chip microcomputer can be used to control the warning bell and the warning light to give an alarm to prompt the staff to check.
