Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an electrical control box. Background Technology

[0002] Currently, electrical control boxes are electrical devices integrated with components for control, measurement, signaling, protection, and regulation. The connection stability of these components is crucial to the performance of the control box. However, power plants are often located in working environments with high vibration levels, posing a significant challenge to the design of electrical control boxes.

[0003] Traditional electrical control boxes are typically mechanically installed, fixed to a support structure or the ground using bolts or welding. This installation method is susceptible to damage from vibration, which can be transmitted to the inside of the control box, causing damage to internal components and affecting the safe operation of the power station. Utility Model Content

[0004] This application provides an electrical control box to solve the problem that vibration can damage internal components in existing electrical control boxes.

[0005] In a first aspect, this application provides an electrical control box mounted on a support platform. The support platform is equipped with a first electromagnetic component and multiple fixing components. The electrical control box includes: a support cylinder, a box body, a locking component, a locking component controller, a second electromagnetic component, a detection sensor, and multiple fixing guides, wherein: The support cylinder is fixed to the support platform, and the first electromagnetic component and all the fixing components are disposed on the support platform inside the support cylinder; The projection position of the box body is located within the projection position of the support cylinder, and there is a gap between the projection position of the outer wall of the box body and the projection position of the inner wall of the support cylinder. Multiple fixing guides are located on the outer periphery of the bottom of the housing, and each fixing member passes through a corresponding fixing guide and is fixed to the locking member; The locking component controller is movably connected to the locking component. When the locking component controller receives a release signal, it drives the locking component to release from the fixing component and releases the fixing guide. The detection sensor is used to detect environmental signals. The output terminal of the detection sensor is connected to the locking component controller, the first electromagnetic component, and the second electromagnetic component, respectively. When the detection sensor detects that the value of the environmental signal is greater than or equal to a preset threshold, it sends a release signal to the locking component controller and a drive signal to the first electromagnetic component and / or the second electromagnetic component, so that the first electromagnetic component and the second electromagnetic component create a gap between the bottom of the housing and the support platform under electromagnetic action.

[0006] Optionally, when the locking component controller receives a locking signal, it drives the locking component to be tightly connected to the fixing component and locks the fixing guide component. When there is a gap between the bottom of the housing and the support platform, if the detection sensor detects that the environmental signal is less than a preset threshold, the detection sensor stops sending drive signals to the first electromagnetic component and / or the second electromagnetic component, and sends a locking signal to the locking component controller.

[0007] Optionally, the fasteners include: a fixing screw or a fixing rod, and the fasteners may include four, with the four fasteners respectively located on the outer periphery of the projection of the housing onto the support platform.

[0008] Optionally, the fixing component includes: a plurality of telescopic controllers, the plurality of telescopic controllers being fixed within the support platform, and each fixing component being connected to the telescopic shaft of one of the telescopic controllers; The fixing member can protrude from the surface of the support platform or retract into the interior of the support platform under the drive of the telescopic shaft of the telescopic controller. The output of the detection sensor is connected to each telescopic controller. When the detection sensor sends a release signal to the locking component controller, the detection sensor sends a retraction signal to the telescopic controller to retract the fixing component into the support platform. Before the detection sensor sends a locking signal to the locking component controller, the detection sensor sends an extension signal to the telescopic controller to make the fixing component protrude from the surface of the support platform.

[0009] Optionally, a peripheral mounting plate is provided at the bottom of the housing, and the fixing guide is a mounting hole that penetrates the mounting plate, or a mounting groove that opens at the edge of the mounting plate, wherein the area of ​​the mounting hole or the opening of the mounting groove is larger than the outer diameter of the fixing screw or fixing rod.

[0010] Optionally, the top end of the fixing member is provided with a limiting fixing structure, and the locking member is provided with a limiting engagement structure that cooperates with the limiting structure. The limiting engagement structure can be connected to or released from the limiting fixing structure. The locking component controller is a drive motor. The locking component is connected to the drive shaft of the drive motor and can be connected to or released from the limiting and fixing structure under the drive of the drive shaft.

[0011] Optionally, the support cylinder includes: a cylinder body and a cylinder body lifting controller, wherein the cylinder body lifting controller is disposed within the support platform, and the cylinder body is connected to the lifting rod of the cylinder body lifting controller; The cylinder can protrude from the surface of the support platform or retract into the interior of the support platform under the action of the lifting rod of the cylinder lifting controller; the initial state of the cylinder is that it is located inside the support platform. The output of the detection sensor is connected to the cylinder lifting controller. When the detection sensor detects an environmental signal greater than or equal to a preset threshold, the detection sensor sends a lifting signal to the cylinder lifting controller to make the cylinder protrude from the surface of the support platform. And, if the detection sensor detects an environmental signal less than the preset threshold, the detection sensor sends a lowering signal to the cylinder lifting controller to make the cylinder descend into the surface of the support platform.

[0012] Optionally, a third annular electromagnetic component is provided on the inner wall of the support cylinder, and a fourth annular electromagnetic component is provided on the outer wall of the housing corresponding to the position of the support cylinder. The third and fourth electromagnetic components cooperate to stabilize the housing on the support cylinder.

[0013] Optionally, the detection sensor includes: a first vibration sensor, a second vibration sensor, and a signal processor, wherein, The first vibration sensor is mounted on the housing; the second vibration sensor is mounted on the support platform. The input terminal of the signal processor is connected to the first vibration sensor and the second vibration sensor respectively, and is used to calculate the difference between the first detection signal collected by the first vibration sensor and the second detection signal collected by the second vibration sensor; if the difference between the first detection signal and the second detection signal is greater than a preset threshold, the output terminal of the signal processor is used as the output terminal of the detection sensor, and the average of the first detection signal and the second detection signal is output as the environmental signal.

[0014] Secondly, a control method for an electrical control box is provided. This method is applied to the electrical control box described in any of the foregoing embodiments. In the initial state, each of the fixing members in the electrical control box passes through a corresponding fixing guide and is fixed to the locking member. The method: Detect environmental signals using sensors; If the value of the environmental signal is greater than or equal to a preset threshold, the detection sensor sends a release signal to the locking component controller and a drive signal to the first electromagnetic component and / or the second electromagnetic component, so that the first electromagnetic component and the second electromagnetic component create a gap between the bottom of the housing and the support platform under electromagnetic action.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: In the embodiment of this application, the electrical control box can be fixed between the mounting plate and the support plate of the box body during normal use by the locking component. When vibration is detected, the detection sensor can first release the locking component through the locking component controller when the value of the detected environmental signal is greater than or equal to a preset threshold. Then, it controls the first electromagnetic component and the second electromagnetic component to send drive signals. The magnetic repulsion between the first electromagnetic component and the second electromagnetic component can suspend the box body. When the box body is suspended, the support cylinder can also protect the box body and prevent it from tipping over. This creates a gap between the box body and the support platform, preventing vibration from being transmitted from the support platform to the box body, thereby preventing vibration from damaging the components inside the box body.

Figure 5 A schematic diagram of the support platform provided in the embodiments of this application. Figure 6 This is a schematic diagram of device connections provided in an embodiment of this application.

[0022] See Figures 1-6 As shown, this application embodiment provides an electrical control box 100, which is installed on a support platform 200. The support platform 200 is provided with a first electromagnetic component 204 and a plurality of fixing components 202. The electrical control box 100 includes: a support cylinder 205, a box body 101, a locking component 108, a locking component controller 302, a second electromagnetic component 106, a detection sensor 301, and a plurality of fixing guides 105.

[0023] See Figure 1 As shown, the enclosure 101 is provided with two enclosure doors 107. An observation window 102 and an operation switch 103 can also be provided on the enclosure doors respectively, so that the operator can directly observe the condition of the enclosure components through the observation window 102 from the outside of the enclosure, and directly connect or disconnect the components inside the enclosure through the operation switch 103.

[0024] See Figure 2 and Figure 5As shown, the support cylinder 205 is fixed to the support platform 200. A support plate 201 is provided on the support platform, and the support cylinder 205 is fixed around the support plate 201 and perpendicular to it. The outer width of the support cylinder 205 is larger than the outer dimensions of the electrical control box 100. For easier fixing of the electrical control box 100 inside the support cylinder, see [reference needed]. Figure 2 As shown, the first electromagnetic component 204 and all the fixing components 202 are disposed on the support platform 200 inside the support cylinder 205, specifically on the support plate 201 on the support platform.

[0025] See Figure 2 As shown in the figure (support cylinder 205 is not shown), the projected position of the box body 101 is located within the projected position of the support cylinder 205, and there is a gap between the projected position of the outer wall of the box body 101 and the projected position of the inner wall of the support cylinder 205. This means that after the box body 101 is properly placed, it can avoid pressing against the inner walls of the support cylinder 205. During installation, the box body can be firmly fixed to the support plate, and at this time, it will not contact the support cylinder. When the box body floats, the support cylinder can protect the box body from all sides, and even if the box body occasionally contacts the support cylinder, it will not cause the box body to tip over.

[0026] See Figures 1-5 As shown, a mounting plate 104 is provided at the bottom of the housing 101, and multiple fixing guides 105 are located on the outer periphery of the mounting plate 104 at the bottom of the housing 101. The fixing guides 105 in the figure can be four through holes at the four corners; in other embodiments, the number of through holes can be six or eight, etc. Each fixing member 202 corresponds to a fixing guide 105. During installation, each fixing member 202 passes through a corresponding fixing guide 105 and is fixed to the locking member 108. In this embodiment, the fixing member 202 can be a screw, and the fixing guide 105 can be a through hole. The inner diameter of the through hole of the fixing guide 105 is larger than the outer diameter of the screw, serving only a guiding function and not limiting or fixing the fixing member. The locking member 108 can be a nut.

[0027] For specific installation instructions, please refer to [link / reference]. Figure 2 As shown, when the housing 101 is placed on the support plate 201, the fixing guide 105 can pass through the fixing member 202. At this time, because the inner diameter of each through hole on the mounting plate 104 is larger than the outer diameter of the screw in the fixing member 202, the housing 101 can still sway left and right and is not fixed. A locking member can be fixed to each screw. By tightening the nut of the locking member, the mounting plate 104 and the support plate 201 of the housing 101 can be fixed together. The outer diameter of the nut of the locking member is larger than the inner diameter of the through hole on the fixing guide 105.

[0028] In other embodiments, the fixing member 202 can be a slide rod or a guide groove, the fixing guide member 105 can be a through hole, and the fixing member 202 is provided with a plurality of horizontally arranged locking holes. The locking member 108 can be a pin or a locking pin, the length of which is greater than the diameter of the through hole. In this way, when the fixing member 202 passes through the through hole of the fixing guide member 105, the locking member 108 can be inserted into the locking hole on the slide rod or the guide groove, preventing the fixing member 202 from coming out of the through hole.

[0029] The locking component controller 302 is movably connected to the locking component 108. When the locking component controller 302 receives a release signal, it drives the locking component 108 to loosen from the fixing component 202, thereby releasing the fixing guide 105 from the locking component 108. In this embodiment, the locking component controller 302 can be a drive motor, with the screw of the drive motor connected to a nut. When the drive motor rotates, the nut can be tightened or loosened, and the locking component will not fall off the fixing component 202 after the nut of the locking component is loosened.

[0030] The detection sensor 301 is used to detect environmental signals. In this embodiment, the detection sensor 301 can be a vibration sensor to sense environmental vibration signals. The output terminal of the detection sensor 301 is connected to the locking component controller 302, the first electromagnetic component 204, and the second electromagnetic component 106, respectively. In a specific application, when the detection sensor 301 detects an environmental signal value greater than or equal to a preset threshold, it sends a release signal to the locking component controller 302 and a drive signal to the first electromagnetic component 204 and / or the second electromagnetic component 106, so that the first electromagnetic component 204 and the second electromagnetic component 106, under electromagnetic action, create a gap between the bottom of the housing and the support platform.

[0031] In the embodiment of this application, the electrical control box can be fixed between the mounting plate and the support plate of the box body during normal use by the locking component. When vibration is detected, the detection sensor can first release the locking component through the locking component controller when the value of the detected environmental signal is greater than or equal to a preset threshold. Then, it controls the first electromagnetic component and the second electromagnetic component to send drive signals. The magnetic repulsion between the first electromagnetic component and the second electromagnetic component can suspend the box body 101. When the box body is suspended, the support cylinder can also protect the box body and prevent it from tipping over. This creates a gap between the box body and the support platform, preventing vibration from being transmitted from the support platform to the box body, thereby preventing vibration from damaging the components inside the box body.

[0032] In one embodiment of this application, when the locking component controller receives a locking signal, it drives the locking component to be securely connected to the fixing component and locks the fixing guide. The locking controller can be a drive motor. In this embodiment, four drive motors can be respectively set at the four corners, and the rotating shaft of each motor is fixedly connected to the locking component (nut), which can drive the locking component to rotate on the fixing component (screw), and the locking component can lock the fixing component and the fixing guide.

[0033] In this embodiment, the drive motor can control the locking mechanism in two ways: locking and releasing. When there is a gap between the bottom of the housing 101 and the support platform 200, the first and second electromagnetic components repel each other magnetically, suspending the housing and support platform by magnetic levitation. If the detection sensor detects that the environmental signal is less than a preset threshold (i.e., the environment is no longer vibrating), the detection sensor stops sending drive signals to the first and / or second electromagnetic components. The housing will no longer be magnetically levitated but will fall and land on the support plate 201 along the fixed guide. At this time, the detection sensor will also send a locking signal to the locking mechanism controller, thereby locking the housing 101 and the support plate 201.

[0034] Therefore, the embodiments of this application can achieve the following: when vibration is detected, the locking member can be released, and the box body is levitated by generating opposite magnetic forces between the first and second electromagnetic members. After the vibration disappears, the first and second electromagnetic members are stopped from being driven, magnetic levitation stops, and the locking member is tightened to re-lock the box body with the support plate 201.

[0035] In this embodiment, the fixing component includes a fixing screw or a fixing rod. The fixing component may include four fixing components, which are respectively located on the outer periphery of the projection of the box body on the support platform.

[0036] The aforementioned fixing component is a screw. In another embodiment of this application, the fixing component further includes: a plurality of telescopic controllers, which are fixed within the support platform, and each fixing component is connected to the telescopic shaft of one of the telescopic controllers. That is, the fixing component itself is directly connected to the telescopic shaft of the telescopic controller.

[0037] Through the above design, the fixing member can protrude from the surface of the support platform or retract into the interior of the support platform under the action of the telescopic shaft of the telescopic controller. The movement of the fixing member can cause it to disengage from or extend into the fixing guide.

[0038] After the aforementioned setup, for ease of control, the output of the detection sensor is connected to each telescopic controller. When the detection sensor sends a release signal to the locking component controller, the detection sensor sends a retraction signal to the telescopic controller to retract the fixing component into the support platform; and, before the detection sensor sends a locking signal to the locking component controller, the detection sensor sends an extension signal to the telescopic controller to make the fixing component protrude from the surface of the support platform.

[0039] With this design, after detecting a vibration signal, the detection sensor sends a release signal to the locking component controller, and then the detection sensor sends a retraction signal to the telescopic controller. This causes the fixing component to retract into or below the support platform along with the telescopic controller. At this point, the fixing component detaches from the fixing guide. Therefore, if it is necessary to levitate the housing, the fixing component and its guide will not interfere with the housing.

[0040] Before the detection sensor sends a locking signal to the locking component controller, the detection sensor sends an extension signal to the telescopic controller, so that the fixing component protrudes from the surface of the support platform and passes through the fixing guide, so that the locking component can lock the fixing component.

[0041] This application provides a power supply box in which the fixing member can be retracted into the support platform when the box needs to be levitated, so as to avoid the fixing member interfering with the stability of the box when it is levitated. When levitation is not required, the fixing member will extend and pass through the fixing guide, so that the locking member can lock the fixing member.

[0042] like Figure 1 As shown, a peripheral mounting plate 104 is provided at the bottom of the housing 101. The fixing guide 105 is a mounting hole that penetrates the mounting plate, or a mounting groove (an outward-facing opening groove) that opens at the edge of the mounting plate. The area of ​​the mounting hole or the opening of the mounting groove is larger than the outer diameter of the fixing screw or fixing rod.

[0043] like Figure 2 As shown, the top of the fixing member 202 is provided with a limiting fixing structure, and the locking member is provided with a limiting engagement structure that cooperates with the limiting structure. The limiting engagement structure can be connected to or released from the limiting fixing structure. In this embodiment, the limiting fixing structure can be threaded, and the corresponding limiting engagement structure can also be threaded. In other embodiments, the limiting engagement structure can be multiple horizontal through holes, and the corresponding limiting engagement structure can be a pin.

[0044] For ease of driving, the locking component controller is a drive motor. The locking component is connected to the drive shaft of the drive motor and can be connected to or released from the limiting and fixing structure under the drive of the drive shaft.

[0045] In other embodiments of this application, while the support cylinder can protect the box from tipping over when it is suspended, it may affect the opening and closing of the box door during normal use. Therefore, in this embodiment, the support cylinder includes a cylinder body and a cylinder lifting controller. The cylinder lifting controller is disposed within the support platform, and the cylinder body is connected to the lifting rod of the cylinder lifting controller.

[0046] The cylinder can protrude from the surface of the support platform or retract into the interior of the support platform under the action of the lifting rod of the cylinder lifting controller; the initial state of the cylinder is that it is located inside the support platform.

[0047] In a specific application, the output of the detection sensor is connected to the cylinder lifting controller. When the detection sensor detects an environmental signal greater than or equal to a preset threshold, the detection sensor sends a lifting signal to the cylinder lifting controller to make the cylinder protrude from the surface of the support platform. Conversely, if the detection sensor detects an environmental signal less than the preset threshold, the detection sensor sends a lowering signal to the cylinder lifting controller to make the cylinder descend into the surface of the support platform.

[0048] In the initial state, the support cylinder of the electrical control box provided in this application embodiment can be hidden inside the support platform (for example, when the support platform is installed on the ground, it is equivalent to the support cylinder being hidden underground). When vibration is detected, the support cylinder will support the platform to rise when a rise signal is received, thereby limiting the box body around the box body when it is suspended and preventing the box body from tipping over.

[0049] In the aforementioned embodiments, the support cylinder and the housing are in direct contact, which can cause friction or compression, damaging the housing. Therefore, in this embodiment, a third annular electromagnetic component can be provided on the inner wall of the support cylinder, and a fourth annular electromagnetic component can be provided on the outer wall of the housing corresponding to the position of the support cylinder. The third and fourth electromagnetic components cooperate to stabilize the housing on the support cylinder.

[0050] In this embodiment, the third and fourth electromagnetic components are energized and cooperate only after the cylinder body of the support cylinder has risen to the correct position in the air of the cylinder lifting controller. This allows the cylinder body to maintain stability within the cylinder body through the repulsive magnetic force between the third and fourth electromagnetic components, preventing it from tipping over.

[0051] In other embodiments of this application, the detection sensor includes: a first vibration sensor, a second vibration sensor, and a signal processor, wherein, The first vibration sensor is mounted on the housing; the second vibration sensor is mounted on the support platform. The input terminal of the signal processor is connected to the first vibration sensor and the second vibration sensor respectively, and is used to calculate the difference between the first detection signal collected by the first vibration sensor and the second detection signal collected by the second vibration sensor; if the difference between the first detection signal and the second detection signal is greater than a preset threshold, the output terminal of the signal processor is used as the output terminal of the detection sensor, and the average of the first detection signal and the second detection signal is output as the environmental signal.

[0052] By using two vibration sensors, false alarms from a single vibration sensor can be avoided, preventing control errors in the enclosure. One sensor can be mounted on the enclosure itself, while the other can be mounted on the ground around the support platform. When the difference between the first and second detection signals exceeds a preset threshold, it indicates significant shaking, thus confirming vibration. During output, the average of the first and second detection signals can be used to avoid the problem of a single sensor's signal being zero, preventing proper drive operation.

[0053] In other embodiments of this application, an electrical control box control method is also provided. The method is applied to the electrical control box described in any of the foregoing embodiments. In the initial state, each of the fixing members in the electrical control box passes through a corresponding fixing guide and is fixed to the locking member. The method: Detect environmental signals using sensors; If the value of the environmental signal is greater than or equal to a preset threshold, the detection sensor sends a release signal to the locking component controller and a drive signal to the first electromagnetic component and / or the second electromagnetic component, so that the first electromagnetic component and the second electromagnetic component create a gap between the bottom of the housing and the support platform under electromagnetic action.

[0054] The method provided in this application embodiment, under normal use, uses a locking component to fix the mounting plate and support plate of the housing. When vibration is detected, the detection sensor can first loosen the locking component through the locking component controller when the detected environmental signal value is greater than or equal to a preset threshold. Then, it controls the first and second electromagnetic components to send drive signals. The magnetic repulsion between the first and second electromagnetic components can suspend the housing 101. When the housing is suspended, the support cylinder can also protect the housing and prevent it from tipping over. This creates a gap between the housing and the support platform, preventing vibration from being transmitted from the support platform to the housing, thereby preventing vibration from damaging the components inside the housing.
