Description

Technical Field

[0001] This invention relates to the field of control cabinets, specifically a high-pressure control cabinet for hydraulic valves. Background Technology

[0002] A control cabinet is an assembly of switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger personnel or surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices can disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters and allow adjustment of certain electrical parameters. They can also provide alerts or signals for deviations from normal operating conditions. Control cabinets are commonly used in power generation, distribution, and substations.

[0003] In the prior art, Chinese invention patent application number CN201910587779.4 discloses a control cabinet, a heat dissipation method, and an air conditioner. The control cabinet includes: a control cabinet body, the control cabinet body including a receiving cavity; and a heat dissipation structure, the heat dissipation structure including a heat dissipation component and a conveying pipe for conveying a first refrigerant. The heat dissipation component and the conveying pipe are disposed in the receiving cavity. The heat dissipation component includes a flow channel for the flow of a second refrigerant. One end of the flow channel is disposed inside the conveying pipe, and the other end is disposed outside the conveying pipe, so that the first refrigerant in the conveying pipe and the second refrigerant in the flow channel can exchange heat.

[0004] In the above case, existing technology integrates components such as frequency converters, PLC controllers, switches, industrial control computers, and circuit breakers inside the control cabinet. During operation, the heat dissipation is relatively large. Furthermore, due to the uneven distribution of circuit components in different parts of the control cabinet, the heat generation varies in different locations. When the heat generation in a certain location or layer of the control cabinet is abnormal, it is difficult to accurately concentrate the cooling air into that location, thereby reducing the heat dissipation effect on the circuit components inside the control cabinet and causing damage to the circuit components due to high temperature.

[0005] Based on this, the present invention designs a high-pressure control cabinet for hydraulic valves to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-pressure control cabinet for hydraulic valves, which solves the problem mentioned in the background art that the control cabinet integrates components such as frequency converters, PLC controllers, switches, industrial control computers, and circuit breakers. During operation, the heat dissipation is large, and due to the uneven distribution of circuit components in different parts of the control cabinet, the heat generation in different locations within the control cabinet varies. When the heat generation in a certain location or layer of the control cabinet is abnormal, it is difficult to accurately concentrate and inject cool air into that location, thereby reducing the heat dissipation effect on the circuit components inside the control cabinet and causing damage to the circuit components due to high temperature.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic valve high-pressure control cabinet, comprising a control cabinet body and a rotary valve integrated with the control cabinet body. The top of the control cabinet body is provided with a flow groove. Electronic components are disposed within the control cabinet body. A U-shaped connecting box is fixedly connected within the control cabinet body. Connecting columns are arrayed and fixedly connected to the two inner side walls of the U-shaped connecting box. Sealing plates are fixedly connected to both ends of the top of each connecting column. The ends of the sealing plates are fixedly connected to the inner wall of the U-shaped connecting box, dividing the U-shaped connecting box into multiple non-interconnected secondary connecting boxes. Temperature sensors are fixedly connected to the secondary connecting boxes at different positions within the control cabinet body. The electronic components are respectively disposed at the secondary connecting boxes. Cold air holes are arrayed on the side walls of the connecting columns. Air inlet pipes are symmetrically fixedly connected to the side walls of the secondary connecting boxes. Several air inlet pipes penetrate the outer side wall of the control cabinet and are then fixedly connected to an external exhaust pipe. An internal exhaust pipe is rotatably connected to the external exhaust pipe.

[0008] The internal exhaust pipe is divided into N sections at equal intervals along the longitudinal direction based on the number of connecting column layers. The surface of each section of the internal exhaust pipe is divided 2 times axially corresponding to the position of the intake pipe. N -1 node, and 2 nodes are selected for each section of the internal exhaust pipe. N-1 Each node has a section hole, and the section holes of each internal exhaust pipe are interconnected, where N is the number of connecting column layers;

[0009] The top of the internal exhaust pipe is fixedly connected to a bellows box, the side wall of the bellows box is provided with an air inlet groove, the bellows box is fixedly connected to the side wall of the control cabinet body, a fan is rotatably connected inside the bellows box, the output shaft end of the fan is drivenly connected to a first motor, the first motor is fixedly connected to the top of the bellows box, the bottom end of the internal exhaust pipe is drivenly connected to a second motor, and the second motor is fixedly connected to the side wall of the control cabinet body.

[0010] In existing technologies, control cabinets integrate components such as frequency converters, PLC controllers, switches, industrial computers, and circuit breakers. These components generate significant heat during operation. Furthermore, due to the uneven distribution of circuit components within the control cabinet, different locations experience varying heat generation. When an abnormal heat generation occurs at a specific location or level, it is difficult to precisely concentrate cool air into that area, thus reducing the cooling effect on the internal circuit components and potentially causing damage due to high temperatures. This technical solution addresses these issues. The specific operation is as follows: First, create joint holes on the internal exhaust pipe according to the number of connecting column layers. When the number of connecting column layers is four, the internal exhaust pipe is first divided into four sections at equal intervals along the longitudinal direction according to the number of connecting column layers. Simultaneously, the surface of each section of the internal exhaust pipe is divided into fifteen nodes at equal intervals along the axial direction corresponding to the position of the intake pipe. Eight nodes are selected and joint holes are opened in each section of the internal exhaust pipe. Observations are made along the longitudinal direction of the internal exhaust pipe and rotated along its axial direction. The following configurations are observed: one section with one joint hole occupying four nodes; two sections with two joint holes occupying six nodes; three sections with three joint holes occupying three nodes; and four sections with four joint holes occupying one node. Then, the external exhaust pipe, internal exhaust pipe, and intake pipe are assembled. When the control cabinet body is at a certain layer... An anomaly occurred, while the temperatures of the other three layers remained normal. Temperature sensors on the corresponding layers detected this anomaly. An external controller then activated the second motor, causing its output shaft to rotate to the appropriate position, connecting the corresponding access hole to the air intake pipe. Driven by the first motor, the fan rotated, drawing in ambient air through the air intake slot into the air box. The air then flowed through the internal exhaust pipe into the connecting column of the corresponding layer. Because sealing plates were fixedly connected to both ends of the connecting column, the U-shaped connecting box was divided into multiple non-interconnected secondary connecting boxes. This ensured that the incoming air could only be exhausted through the cold air vents on the connecting column of that layer, thus protecting the electronic components of that layer. The cooling system rapidly reduces the temperature of electronic components on this layer without affecting components on other layers. Simultaneously, if the temperature of multiple layers of electronic components becomes abnormal, under the joint monitoring of multiple temperature sensors, the second motor drives the internal exhaust pipe to rotate to the corresponding position, connecting the exhaust pipes of each layer with the internal exhaust pipe. This allows natural air to flow in through multiple air intake pipes and be injected into the connecting columns of different layers, thereby cooling multiple layers of electronic components. This precisely concentrates cool air into the location of abnormal heat generation, improving the heat dissipation effect on the internal circuit components of the control cabinet and preventing damage to these components due to high temperatures.

[0011] As a further aspect of the present invention, each of the cooling air vents is fixedly connected to a connecting pipe, and an air intake plate is fixedly connected to the top of the connecting pipe. An arc-shaped groove is formed on the inner side wall of the air intake plate, and rotating blades are slidably connected in an array within the arc-shaped groove. Several rotating blades are fixedly connected to a rotating disk at their ends, and the two side walls of the rotating disk are in contact with the inner wall of the air intake plate. During operation, by setting up the air intake plate, rotating blades, and rotating disk, when external natural air is injected into the connecting pipe through the cooling air vents, it is injected into the air intake plate through the connecting pipe, blowing the rotating blades, thereby causing the rotating disk to rotate and exhausting the natural air, reducing the temperature of the electronic components inside the control cabinet. At the same time, as the rotating blades rotate, the air circulation speed inside the space is increased, thereby improving the heat dissipation effect.

[0012] As a further embodiment of the present invention, heat dissipation plates are fixedly connected to the inner side walls of the control cabinet body. After the top of the heat dissipation plate passes through the connecting column, a heat dissipation fin is fixedly connected to its top. During operation, by setting the heat dissipation plate and the heat dissipation fin, the heat dissipation plate is in close contact with the inner side wall of the control cabinet body to dissipate heat on its surface. When the outside natural wind is injected into the connecting column, the natural wind dissipates the surface temperature of the heat dissipation fin, thereby improving the heat dissipation effect on the inner side wall of the control cabinet.

[0013] As a further embodiment of the present invention, the internal exhaust pipe has a hollow structure, and the internal cavity of the internal exhaust pipe is filled with refrigerant. During operation, since the internal exhaust pipe has a hollow structure and is filled with refrigerant, when the outside natural wind blows into the internal exhaust pipe, the refrigerant cools the internal exhaust pipe, thereby reducing the temperature of the natural wind and improving the heat dissipation effect on the control cabinet body.

[0014] As a further aspect of the present invention, the external exhaust pipe has a hollow structure, and the internal cavity of the external exhaust pipe is filled with a thermal insulation agent. During operation, since the external exhaust pipe has a hollow structure and is filled with a thermal insulation agent, the influence of the external temperature on the internal exhaust pipe can be reduced, thereby improving the cooling effect of the internal exhaust pipe on natural wind and improving the heat dissipation effect on the control cabinet body.

[0015] As a further embodiment of the present invention, the intake pipe is a tapered pipe, including a narrow diameter end and a wide diameter end, wherein the narrow diameter end of the tapered pipe is fixedly connected to the external exhaust pipe, and the wide diameter end is fixedly connected to the connecting post; during operation, the intake pipe is set as a tapered pipe to improve the natural airflow speed.

[0016] As a further aspect of the present invention, a first dust removal screen is fixedly connected inside the air intake slot; during operation, by setting the first dust removal screen, dust in the natural wind is reduced, thereby reducing the amount of dust inside the control cabinet.

[0017] As a further aspect of the present invention, a second dust removal screen is fixedly connected inside the flow channel; during operation, by setting the first dust removal screen, the amount of dust inside the control cabinet is reduced.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention utilizes a U-shaped connecting box, connecting columns, external exhaust pipe, internal exhaust pipe, and air intake pipe to achieve layered heat dissipation for the control cabinet body. Under the joint monitoring of multiple temperature sensors, abnormally heated layers are detected. An external controller controls a second motor to rotate the internal exhaust pipe to the corresponding position, ensuring that the exhaust pipes of each layer are connected to the internal exhaust pipe. This allows natural airflow to be injected into the connecting columns of different layers through the corresponding air intake pipes, thereby dissipating heat from electronic components on multiple layers. This precisely concentrates cool air into the locations of abnormal heat generation, improving the heat dissipation effect on the internal circuit components of the control cabinet and preventing damage to the circuit components due to high temperatures.

[0020] 2. This invention, by setting up an air intake plate, rotating blades, and a rotating disk, allows external natural air to be injected into the connecting pipe through the cooling air hole, and then into the air intake plate through the connecting pipe. This blows the rotating blades, causing the rotating disk to rotate and expel the natural air, thereby reducing the temperature of the electronic components inside the control cabinet. At the same time, the rotation of the rotating blades increases the air circulation speed in the internal space, thereby improving the heat dissipation effect.

[0021] 3. This invention uses a heat dissipation plate and heat dissipation fins to make the heat dissipation plate fit tightly against the inner wall of the control cabinet body and dissipate heat on its surface. When the outside natural wind is injected into the connecting column, the natural wind dissipates the surface temperature of the heat dissipation fins, thereby improving the heat dissipation effect on the inner wall of the control cabinet.

[0022] 4. This invention incorporates a refrigerant-filled internal cavity in the internal exhaust pipe and a thermal insulation agent-filled internal cavity in the external exhaust pipe. When natural air blows into the internal exhaust pipe, the refrigerant cools the pipe, thus lowering the air temperature and improving heat dissipation within the control cabinet. Simultaneously, the hollow structure of the external exhaust pipe, with its internal thermal insulation agent, mitigates the influence of external temperature on the internal exhaust pipe, further enhancing its cooling effect on the natural air and improving overall heat dissipation for the control cabinet.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-12 This invention provides a technical solution: a high-pressure control cabinet for a hydraulic valve, comprising a control cabinet body 1 and a rotary valve 101 integrated with the control cabinet body 1. The top of the control cabinet body 1 is provided with a flow channel 102. Electronic components 103 are installed inside the control cabinet body 1. A U-shaped connecting box 2 is fixedly connected inside the control cabinet body 1. Connecting columns 3 are arrayed and fixedly connected to the two inner side walls of the U-shaped connecting box 2. Sealing plates 301 are fixedly connected to both ends of the top of the connecting columns 3. The ends of the sealing plates 301 are fixedly connected to the inner wall of the U-shaped connecting box 2. The U-shaped connecting box 2 is divided into multiple non-connected secondary connecting boxes 201. Temperature sensors 4 are fixedly connected to the secondary connecting boxes 201 at different positions inside the control cabinet body 1. Electronic components 103 are respectively set at the secondary connecting boxes 201. Cold air holes 5 are arrayed on the side walls of the connecting columns 3. Air inlet pipes 6 are symmetrically fixedly connected to the side walls of the secondary connecting boxes 201. The ends of several air inlet pipes 6 pass through the outer side wall of the control cabinet and are fixedly connected to the external exhaust pipe 7. An internal exhaust pipe 8 is rotatably connected inside the external exhaust pipe 7.

[0040] The internal exhaust pipe 8 is divided into N sections at equal intervals along the longitudinal direction using the number of connecting columns 3. The surface of each section of the internal exhaust pipe 8 is divided 2 times axially corresponding to the position of the intake pipe 6. N -1 node 801, each section has an internal exhaust pipe 8, each selected 2 N-1 Each node 801 has a section hole 802, and the section holes 802 of the exhaust pipe 8 in each section are interconnected. N is the number of connecting columns 3 layers.

[0041] The top of the internal exhaust pipe 8 is fixedly connected to the air box 9. The side wall of the air box 9 is provided with an air inlet slot 10. The air box 9 is fixedly connected to the side wall of the control cabinet body 1. A fan 11 is rotatably connected inside the air box 9. The output shaft end of the fan 11 is driven to the first motor 12. The first motor 12 is fixedly connected to the top of the air box 9. The bottom end of the internal exhaust pipe 8 is driven to the second motor 13. The second motor 13 is fixedly connected to the side wall of the control cabinet body 1.

[0042] In existing technologies, control cabinets integrate components such as frequency converters, PLC controllers, switches, industrial computers, and circuit breakers. These components generate significant heat during operation. Furthermore, due to the varying distribution of circuit components within the control cabinet, different locations experience different heat generation. When an abnormal heat generation occurs at a specific location or level, it is difficult to precisely concentrate cool air into that location, thus reducing the cooling effect on the internal circuit components and potentially causing damage due to high temperatures. This technical solution addresses these issues. The specific operation is as follows: First, according to the number of layers in the connecting column 3, a joint hole 802 is opened on the internal exhaust pipe 8. When the number of layers in the connecting column 3 is four, the internal exhaust pipe... 8 is divided into four sections longitudinally at equal intervals based on the number of layers of the connecting column 3. Simultaneously, the surface of the internal exhaust pipe 8 in each section is axially divided into fifteen nodes 801 at equal intervals corresponding to the position of the intake pipe 6. Eight nodes 801 are selected for each section of the internal exhaust pipe 8, and joint holes 802 are opened. Observations are made longitudinally along the internal exhaust pipe 8 and rotated axially. The following configurations are observed: one section with one joint hole 802 occupying four nodes 801; two sections with two joint holes 802 occupying six nodes 801; three sections with three joint holes 802 occupying three nodes 801; and four sections with four joint holes 802 occupying one node 801. Subsequently, the external exhaust pipe 7, internal exhaust pipe 8, and intake pipe 6 are assembled. When a certain layer of the control cabinet body 1... An anomaly occurred at one of the three floors, while the temperatures of the other three floors remained normal. Temperature sensors on the corresponding floors detected this anomaly. Subsequently, an external controller activated the second motor 13, causing its output shaft to rotate to the corresponding position, connecting the corresponding joint hole 802 to the air intake pipe 6. Driven by the first motor 12, the fan 11 rotated, drawing in outside air through the air intake slot 10 into the air box 9. The air then flowed through the internal exhaust pipe 8 into the connecting column 3 on the corresponding floor. Since sealing plates 301 were fixedly connected to both ends of the connecting column 3, the U-shaped connecting box 2 was divided into multiple non-connected secondary connecting boxes 201. This ensured that the incoming air could only be exhausted through the cold air vents 5 on the connecting column 3 of that floor, thus preventing the air from being discharged. The sub-component 103 dissipates heat, causing the temperature of the electronic component 103 on this layer to drop rapidly without affecting the electronic components 103 on other layers. At the same time, if the temperature of multiple layers of electronic components 103 is abnormal, under the joint monitoring of multiple temperature sensors, the second motor 13 drives the internal exhaust pipe 8 to rotate to the corresponding position, so that the exhaust pipes of the corresponding layers are connected to the internal exhaust pipe 8. This allows the natural air flowing in through multiple air intake pipes 6 to be injected into the connecting columns 3 of different layers, thereby dissipating heat from the electronic components 103 on multiple layers. This precisely concentrates the cool air into the abnormally hot location, improving the heat dissipation effect on the circuit components inside the control cabinet and preventing damage to the circuit components inside the control cabinet due to high temperature.

[0043] As a further embodiment of the present invention, each of the air vents 5 is fixedly connected to a connecting pipe 14, and the top end of the connecting pipe 14 is fixedly connected to an air intake plate 15. An arc-shaped groove 16 is provided on the inner side wall of the air intake plate 15, and rotating blades 17 are slidably connected in an array within the arc-shaped groove 16. Several rotating blades 17 are fixedly connected to a rotating disk 18 at their ends, and the two side walls of the rotating disk 18 are in contact with the inner wall of the air intake plate 15. During operation, by setting up the air intake plate 15, rotating blades 17 and rotating disk 18, when the outside natural wind is injected into the connecting pipe 14 through the air vents 5, it is injected into the air intake plate 15 through the connecting pipe 14, blowing the rotating blades 17, thereby causing the rotating disk 18 to rotate, exhausting the natural wind, reducing the temperature of the electronic components 103 in the control cabinet, and at the same time, the rotation of the rotating blades 17 increases the air circulation speed in the internal space, thereby improving the heat dissipation effect.

[0044] As a further embodiment of the present invention, heat dissipation plates 19 are fixedly connected to the inner sidewalls of the control cabinet body 1. After the top of the heat dissipation plate 19 passes through the connecting column 3, a heat dissipation fin 20 is fixedly connected to its top. During operation, by setting the heat dissipation plate 19 and the heat dissipation fin 20, the heat dissipation plate 19 is in close contact with the inner sidewall of the control cabinet body 1 to dissipate heat on its surface. When the outside natural wind is injected into the connecting column 3, the natural wind dissipates the surface temperature of the heat dissipation fin 20, thereby improving the heat dissipation effect on the inner sidewall of the control cabinet.

[0045] As a further aspect of the present invention, the internal exhaust pipe 8 has a hollow structure, and the internal cavity of the internal exhaust pipe 8 is filled with refrigerant 803. During operation, since the internal exhaust pipe 8 has a hollow structure and is filled with refrigerant 803, when the outside natural wind blows into the internal exhaust pipe 8, the refrigerant 803 cools the internal exhaust pipe 8, thereby reducing the temperature of the natural wind and improving the heat dissipation effect on the control cabinet body 1.

[0046] As a further embodiment of the present invention, the external exhaust pipe 7 has a hollow structure, and the internal cavity of the external exhaust pipe 7 is provided with a heat-insulating agent 701. During operation, since the external exhaust pipe 7 has a hollow structure and is provided with a heat-insulating agent 701, the influence of the external temperature on the internal exhaust pipe 8 can be reduced, thereby improving the cooling effect of the internal exhaust pipe 8 on natural wind and improving the heat dissipation effect on the control cabinet body 1.

[0047] As a further embodiment of the present invention, the intake pipe 6 is a tapered pipe, including a narrow diameter end 601 and a wide diameter end 602, wherein the narrow diameter end 601 of the tapered pipe is fixedly connected to the external exhaust pipe 7, and the wide diameter end 602 is fixedly connected to the connecting post 3; during operation, the intake pipe 6 is set as a tapered pipe to improve the natural airflow speed.

[0048] As a further embodiment of the present invention, a first dust removal screen 21 is fixedly connected inside the air intake slot 10; during operation, by setting the first dust removal screen 21, dust in the natural wind is reduced, and the amount of dust in the control cabinet is reduced.

[0049] As a further embodiment of the present invention, a second dust removal screen 22 is fixedly connected inside the flow channel 102; during operation, the amount of dust inside the control cabinet is reduced by setting the first dust removal screen 21.

[0050] Working principle: First, according to the number of connecting columns 3, section holes 802 are opened on the internal exhaust pipe 8. When the number of connecting columns 3 is four, the internal exhaust pipe 8 is first divided into four sections longitudinally at equal intervals according to the number of connecting columns 3. At the same time, the surface of each section of the internal exhaust pipe 8 is divided into fifteen nodes 801 axially at equal intervals corresponding to the position of the intake pipe 6. Eight nodes 801 are selected in each section of the internal exhaust pipe 8 and section holes 802 are opened. Among them, when observed longitudinally along the internal exhaust pipe 8 and when observed by rotating the internal exhaust pipe 8 axially, each section has only one section hole 802, each section occupies four nodes 801, and each section has two section holes 802. 02 Each section occupies six nodes 801, each section has three joint holes 802, each section occupies three nodes 801, and each section has four joint holes 802. Each section occupies one node 801. Then, the external exhaust pipe 7, internal exhaust pipe 8, and intake pipe 6 are assembled. When an abnormality occurs at a certain layer of the control cabinet body 1, while the temperature of the other three layers is normal, it is detected by the temperature sensor of the corresponding layer. Then, the external controller controls the second motor 13, so that the output shaft of the second motor 13 rotates to the corresponding position, so that the corresponding joint hole 802 is connected to the intake pipe 6, driven by the first motor 12. The fan 11 rotates, drawing in outside air through the air intake slot 10 into the air box 9. The air then flows through the internal exhaust pipe 8 into the corresponding connecting column 3. Since sealing plates 301 are fixedly connected to both ends of the connecting column 3, the U-shaped connecting box 2 is divided into multiple non-interconnected secondary connecting boxes 201. This ensures that the incoming air can only be exhausted through the cooling vents 5 on the connecting column 3 of that layer, thereby dissipating heat from the electronic components 103 of that layer. This allows the temperature of the electronic components 103 in that layer to drop rapidly without affecting the electronic components 103 in other layers. If the temperature of the multi-layer electronic components 103 is abnormal, under the joint monitoring of multiple temperature sensors, the second motor 13 drives the internal exhaust pipe 8 to rotate to the corresponding position, so that the exhaust pipes of the corresponding layers are connected to the internal exhaust pipe 8. This allows the natural air flowing in through multiple air intake pipes 6 to be injected into the connecting columns 3 of different layers, thereby dissipating heat from the electronic components 103 on multiple layers. This ensures that the cool air is precisely concentrated and injected into the abnormally hot location, improving the heat dissipation effect on the circuit components inside the control cabinet and preventing damage to the circuit components inside the control cabinet due to high temperature.
