Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment protection, and in particular to a protection system for an electrical equipment operating panel. Background Art

[0002] Electrical equipment generally includes an operation panel for facilitating the operation of the control system. For example, the operation panel of the station terminal can be used by staff to perform equipment maintenance and debugging. However, the operation panel of the station terminal is directly exposed to the outside and is easily affected by dust and moisture, which affects its use.

[0003] At present, the common practice is to add a protective cover to the outside of the operation panel. For example, the Chinese utility model patent with the authorization announcement number CN211456672U discloses a microcomputer integrated protection device (i.e., an electrical device) with dust and moisture-proof functions, which includes a device body, an annular protrusion is arranged on the outer wall of the body, a control panel is arranged inside the annular protrusion, and a protective cover is arranged on the outer side of the annular protrusion. The protective cover is a cylindrical structure with one end open, and its open end is in contact with the outer wall of the device body. The outer wall of the device body is also symmetrically provided with two horizontal plates. The protective cover is fixedly installed between the two horizontal plates through a snap-fit ​​mechanism to prevent the control panel from being exposed to the outside. Among them, the snap-fit ​​mechanism includes a conical card block, and a conical card slot is arranged on the protective cover. When in use, the conical card block is squeezed by the conical surface to move the conical card block to open it.

[0004] The microcomputer integrated protection device in the above patent requires the entire protective cover to be manually removed before using the control panel, and then manually installed after use. The locking mechanism needs to be squeezed hard to open, which is laborious and inconvenient to operate. In addition, when the device fails, the equipment itself is dangerous to be electrified. If the protective cover is still opened manually at this time, there is a risk of electric shock to the operator, and the operator's safety cannot be guaranteed. Summary of the invention

[0005] The object of the present invention is to provide a protection system for an electrical equipment operating panel with high automation and high safety.

[0006] To achieve the above purpose, the protection system of the electrical equipment operation panel in the present invention adopts the following technical solutions:

[0007] The protection system of the operating panel of electrical equipment includes:

[0008] A protective tube, one end of which is used to be fixed on the equipment body of the electrical equipment so as to cover the operation panel of the electrical equipment;

[0009] A protective cover is installed at the other end of the protective tube;

[0010] A power device is connected to the protective cover in a driving manner and is used to drive the protective cover to move so that the protective cover is closed to enclose the operation panel in the protective tube, or the protective cover is opened to facilitate observation of the operation panel;

[0011] A control switch, connected to the power device, for an operator to manually control the start of the power device;

[0012] A controller connected to the power device and used to automatically control the start of the power device according to the received signal, and the controller is also used to connect to the fault handling system of the equipment body;

[0013] A proximity sensor is connected to the controller and is used to be installed on the equipment body, protective cylinder or protective cover to detect whether an operator is approaching the protective cylinder or protective cover;

[0014] When the equipment is working normally, the operator manually controls the start of the power device through the control switch to open or close the protective cover;

[0015] When a fault occurs in the equipment body, the controller receives a fault signal from the fault handling system and controls the proximity sensor to start working according to the fault signal; when the proximity sensor detects that an operator is approaching the protective cylinder or protective cover, the proximity sensor feeds back the detection signal to the controller, and the controller automatically controls the start of the power device to open the protective cover to facilitate the operator to observe the operation panel; when the proximity sensor detects that the operator has left, the proximity sensor feeds back the detection signal to the controller, and the controller automatically controls the start of the power device to close the protective cover.

[0016] The beneficial effect of the above technical solution is that the protection system of the present invention controls the opening or closing of the protective cover by setting a power device, and controls the start of the power device by setting a control switch and a controller. Specifically, the operator controls the opening or closing of the protective cover by pressing the control switch, or the controller controls the opening or closing of the protective cover by receiving a signal, and there is no need to manually remove or install the protective cover, which is convenient to operate, labor-saving, and highly automated.

[0017] At the same time, the protection system of the present invention also includes a proximity sensor. When the equipment body fails, the fault handling system of the equipment sends a fault signal. After receiving the fault signal, the controller controls the proximity sensor to start working. Then the proximity sensor can detect the approach or departure of the operator and feed back the detection signal to the controller. The controller controls the protective cover to automatically open or close, avoiding the risk of electric shock caused by the operator touching the equipment body or the control switch when opening the protective cover when the equipment body fails and the equipment body or the control switch is energized. This has the advantage of high safety.

[0018] Furthermore, the protective cover is hinged on the protective cylinder.

[0019] The beneficial effect of the above technical solution is that the protective cover is hinged on the protective tube, and the structure is simple and easy to install.

[0020] Furthermore, the power device is an electric push rod hinged between the protective tube and the protective cover, the electric push rod includes a motor, and the control switch and the controller are respectively connected to the motor control to control the forward and reverse rotation of the motor.

[0021] The beneficial effect of the above technical solution is that according to the structural form in which the protective cover is hinged on the protective tube, the power device is configured as an electric push rod hinged between the protective tube and the protective cover, which has a simple structure and is easy to use.

[0022] Furthermore, the electric push rod is arranged in the protective tube, one end of the electric push rod is hinged on the inner wall of the protective tube, and the other end of the electric push rod is hinged on the inner wall of the protective cover.

[0023] The beneficial effect of the above technical solution is that the electric push rod is arranged in the protective tube, which can protect the electric push rod from dust and moisture.

[0024] Furthermore, the upper end of the protective cover is hinged on the protective tube, and the electric push rod is located on the upper side of the protective tube.

[0025] The beneficial effect of the above technical solution is that: with this structure, when the protective cover is opened, it is located on the upper side of the operator's head, which will not hinder the operator from approaching the operation panel and facilitates the operator to view the operation panel at close range.

[0026] Furthermore, the hinged position between the electric push rod and the protective cover is located at the upper middle side of the protective cover.

[0027] The beneficial effect of the above technical solution is that when the protective cover is opened, the push rod has a short stroke and does not need to be configured with a long-stroke push rod, which can reduce the configuration cost.

[0028] Furthermore, the controller is also used to send fault information to an operator to notify the operator to handle the fault.

[0029] The beneficial effect of the above technical solution is that it is convenient for operators to handle faults in a timely manner.

[0030] Furthermore, the protective tube is a square tube, and the protective cover is a square cover.

[0031] The beneficial effect of the above technical solution is that: the protective tube is a square tube, and the protective cover is a square cover, which facilitates the installation and connection of the protective tube and the protective cover.

[0032] Furthermore, the protective cover is in the shape of a flat plate.

[0033] The beneficial effect of the above technical solution is that the protective cover is in a flat plate shape, has a simple structure and is easy to process.

[0034] Furthermore, a sealing gasket is provided at the joint position between the protective cover and the protective tube.

[0035] The beneficial effect of the above technical solution is that a sealing gasket is provided at the joint position between the protective cover and the protective tube, thereby improving the sealing performance of the protective system. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0041] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0042] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0043] The implementation of a protection system for an electrical equipment operation panel (hereinafter referred to as the protection system) of the present invention is as follows: Figure 1 As shown, the electrical equipment in this embodiment takes a station terminal as an example, and the station terminal includes a device body 4 and an operation panel 5 arranged on the outer wall of the device body 4.

[0044] Specifically, the protection system includes a protection tube 1, one end of which is fixed to the equipment body 4 of the station terminal so as to cover the operation panel 5 of the station terminal, and the other end is provided with a protection cover 3. Specifically, the protection cover 3 is in the shape of a flat plate, and its upper end is hinged on the protection tube 1. To facilitate the hinge between the protection tube 1 and the protection cover 3, the protection tube 1 is set as a square tube, and the protection cover 3 is set as a square cover. In addition, in order to improve the sealing performance of the protection system, a sealing gasket (not shown in the figure) is provided at the joint position between the protection cover 3 and the protection tube 1.

[0045] The protection system also includes a power device that is transmission-connected to the protective cover 3 to drive the protective cover 3 to move, so that the protective cover 3 is closed to enclose the operation panel 5 in the protective tube 1, or the protective cover 3 is opened to facilitate observation of the operation panel 5. Specifically, the power device in this embodiment is an electric push rod 2, and the electric push rod 2 includes a motor (not shown in the figure). The electric push rod 2 is arranged in the protective tube 1 and is located on the upper side of the protective tube 1. One end of the electric push rod 2 is hinged on the inner wall of the protective tube 1, and the other end is hinged on the middle upper side of the inner wall of the protective cover 3. When the electric push rod 2 is extended, the protective cover 3 is pushed to open, and when the electric push rod 2 is retracted, the protective cover 3 is pulled to close.

[0046] The protection system also includes a control switch (not shown in the figure), which is connected to the motor of the electric push rod 2 to control the forward and reverse rotation of the motor. When the station terminal is working normally, when the operator needs to view the data, he presses the "on" key on the control switch, the motor rotates forward, the electric push rod 2 extends, and then pushes the protective cover 3 to open; when the "off" key is pressed, the motor reverses, the electric push rod 2 retracts, and the protective cover 3 is pulled closed, so that the protection system reaches a completely sealed closed state, which is convenient and labor-saving to operate.

[0047] The protection system also includes a controller (not shown in the figure), which is connected to the motor to control the forward and reverse rotation of the motor. The controller is also connected to the fault handling system of the equipment body 4 to receive a fault signal issued by the fault handling system. At the same time, the controller is also used to send the fault information to the operator to notify the operator to handle the fault.

[0048] The protection system also includes a proximity sensor (not shown in the figure), which is installed on the protective cover 3 and is used to detect whether an operator is close to the protective cover 3. The proximity sensor is connected to the controller. When the controller receives a fault signal from the fault handling system, the controller will control the proximity sensor to start working, and then the proximity sensor will feed back the detection signal of whether a person is approaching to the controller, so that the controller can automatically control the start of the electric push rod 2 to open or close the protective cover 3.

[0049] Specifically, when the equipment is working normally, the operator opens or closes the protective cover by pressing the corresponding button of the control switch; when the terminal fails, the working process of the protection system is as follows: Figure 2 As shown, the fault handling system of the equipment body 4 sends a fault signal, the controller receives the fault signal, and controls the proximity sensor to start working according to the fault signal; at the same time, the controller also sends the fault information to the operator to notify the operator to handle the fault. When the proximity sensor detects that an operator is approaching the protective cover 3, the proximity sensor feeds back the detection signal to the controller, and the controller automatically controls the start of the motor, the motor rotates forward, and the electric push rod 2 extends, thereby pushing the protective cover 3 to open, so that the operator can observe the operation panel 5; when the proximity sensor detects that the operator has left, the proximity sensor feeds back the detection signal to the controller, and the controller automatically controls the start of the motor, the motor reverses, the electric push rod 2 retracts, and pulls the protective cover 3 to close. During the entire operation, the operator does not need to touch the protective tube 1 and the protective cover 3, avoiding the risk of electric shock to the operator due to the protection tube 1 or the protective cover 3 being charged in the event of equipment failure.

[0050] The protection system in this embodiment controls the opening or closing of the protection cover by setting an electric push rod, and controls the start of the electric push rod by setting a control switch and a controller, without manual operation, and has the advantages of convenient operation, labor saving and high degree of automation. In addition, the protection system also includes a proximity sensor, which only starts to work when the equipment fails, which not only ensures the personal safety of the operator in the event of a failure, but also avoids the failure of the dust and moisture proof effect of the protection system due to frequent opening and closing due to the passing of people when the equipment is working normally.

[0051] In other embodiments of the protection system for the operating panel of an electrical device, the electrical device may also be a microcomputer protection device, or other electrical device with an operating panel.

[0052] In other embodiments of the protection system for the operating panel of an electrical device, no sealing gasket is provided at the joint between the protection cover and the protection cylinder.

[0053] In other embodiments of the protection system for the operating panel of an electrical device, the protection cover is not a flat plate but a flanged plate with flanges.

[0054] In other embodiments of the protection system for the operating panel of an electrical device, the protection cylinder is a circular cylinder, and the protection cover is a circular cover.

[0055] In other embodiments of the protection system of the electrical equipment operation panel, the controller will not send the fault information to the operator. For the electrical equipment, a main control room is provided to match the fault handling system. When a fault occurs in the equipment, the fault handling system will send a fault signal to the main control room. After the personnel in the main control room discover it, they can handle the fault.

[0056] In other embodiments of the protection system for the operating panel of an electrical device, the hinge position between the electric push rod and the protective cover may also be arranged in the middle or the lower side of the middle of the inner wall of the protective cover.

[0057] In other embodiments of the protection system for the operating panel of an electrical device, the protection cover may also be hinged in such a way that the lower end is hinged on the protection tube, and in this case, the electric push rod is located at the lower side of the protection tube.

[0059] In other embodiments of the protection system for the electrical equipment operation panel, the power device may also be a hydraulic cylinder or a pneumatic cylinder.

[0060] In other embodiments of the protection system of the electrical equipment operating panel, the protective cover can also be hinged in the following manner: a rotating shaft is fixed on the protective cover, and the protective cover is hinged to the protective cylinder through the rotating shaft. The power device is a motor transmission connected to the rotating shaft, and the forward and reverse rotation of the motor can directly drive the forward and reverse rotation of the rotating shaft, thereby controlling the opening or closing of the protective cover.

[0061] In other embodiments of the protection system of the electrical equipment operating panel, the protective cover is not hinged on the protective cylinder. For example, the protective cylinder is provided with a slide groove extending up and down at the left end of the connection with the protective cover, and a sliding block cooperating with the up and down guide of the slide groove is fixed to the left end of the protective cover. At this time, the power device is an electric push rod, and the electric push rod is arranged outside the protective cylinder, one end of the electric push rod is connected to the protective cylinder, and the other end is connected to the protective cover. The electric push rod directly drives the protective cover to move up and down by telescoping, so as to realize the opening or closing of the protective cover.

[0062] In other embodiments of the protection system for the operation panel of an electrical device, the proximity sensor may also be installed on the device body or the protection cylinder.
