Description

Technical Field

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. The present invention adopts a fan assembly, a one-way cylinder, an extrusion plate, a limit block, a limit frame, a damping telescopic rod and a buffer spring. Through the ingenious design of the moving seat and the carrying plate, the user can easily move the control cabinet out of the protective frame, which greatly simplifies the installation and disassembly process and improves maintenance efficiency. When the fan assembly is in operation, it can effectively suck the air in the protective frame, so that the air inside the protective frame forms a relatively thin or near-vacuum state, creating a stable operating environment for the control cabinet. As the air pressure in the protective frame decreases, the extrusion plate, the moving rod and the limit block will automatically move away from the limit frame, intelligently releasing the limit on the limit frame and the carrying plate, ensuring that the control cabinet can move freely when needed. The buffer spring and the damping telescopic rod in the device provide excellent buffering and shock absorption functions, effectively protecting the safety and stability of the control cabinet when it is moved or impacted by external forces. The vacuum state not only optimizes the operating environment of the control cabinet, but also significantly reduces the noise during the operation of the control cabinet, thereby improving the working comfort of the equipment.

[0027] 2. In the present invention, a contact plate, a connecting frame, an extrusion plate, a piston plate, an extrusion column, a heat conducting plate, a thermal pad, a pin assembly and a spring are used. The movable seat is uniquely designed and can effectively squeeze the contact plate and the extrusion plate to move backward. At the same time, through the ingenious design of the intermediate tube, the gas in the first connecting cylinder is sucked into the connecting frame, thereby realizing rapid gas transfer. During the gas suction process, the piston plate, the cross bar and the extrusion column are controlled to realize the coordinated movement forward, demonstrating the precise control ability of the device. The extrusion column pushes the heat conducting plate to rotate around the pin assembly. At this time, the second spring is cleverly compressed, and the heat conducting plate rotates to be in close contact with the surface of the control cabinet. A stable heat dissipation channel is formed between the heat conducting plate, the thermal pad and the control cabinet, ensuring that the control cabinet can maintain excellent heat dissipation effect while in contact with external air, dust and moisture. This device not only provides reliable safety protection, but also cleverly solves the heat dissipation problem of the control cabinet, realizing the perfect combination of protection and heat dissipation, and effectively reduces the operating temperature of the control cabinet by optimizing the heat dissipation mechanism, thereby improving the stability and service life of the equipment.

[0028] 3. The present invention utilizes a second connecting tube, a one-way valve, a pressure relief valve, a damping pressure plate, a second piston rod, a connecting pin, a rotating rod, and a sliding frame. When significant heat or explosion occurs inside the control cabinet, the expanding gas rapidly flows through the connector, bellows, and one-way valve into the second connecting tube, ensuring a rapid emergency response. The design of the second connecting tube significantly increases the space available for gas flow during an explosion, effectively mitigating the sharp rise in internal pressure. The flowing gas pushes the damping pressure plate to move within the second connecting tube. Precise control of the second piston rod and connecting pin enables the rotating rod to move, thereby controlling the downward movement of the sliding frame. This downward movement of the sliding frame increases the energy consumption of gas flow, providing rapid pressure relief and energy consumption in the event of an explosion, effectively reducing the hazards caused by the explosion. Effective pressure relief and energy consumption are achieved in the event of an explosion, while the sliding frame also cleans the surface of the thermal pad, further enhancing the safety and protection of the control cabinet. Through multiple design features, this device significantly improves the safety of the control cabinet in high-temperature or explosive conditions, providing a solid guarantee for equipment operation.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] Please see the attached Figure 1 -Attached Figure 10The present invention provides a technical solution: a boiler control cabinet safety protection device, comprising a protection frame 1, a revolving door 2 hinged on the front of the protection frame 1, a fan assembly 4 is provided on the protection frame 1, and an exhaust pipe 5 connected to the protection frame 1 is connected on the side of the fan assembly 4. An electric guide rail 6 is installed on the inner bottom wall of the protection frame 1, and a sliding bearing mechanism 7 is slidably connected in the electric guide rail 6. A limiting mechanism 17 is fixedly installed in the sliding bearing mechanism 7, and an extrusion adjustment mechanism 8 connected to the inner wall of the protection frame 1 is provided on the back of the sliding bearing mechanism 7. The extrusion adjustment mechanism 8 is connected to the outside of the intermediate pipe 9, and the end of the intermediate pipe 9 is connected to the movement control mechanism 10 provided on the inner wall of the protection frame 1. The left and right side surfaces of the inner wall of the protection frame 1 are connected to a rotating heat conducting mechanism 11, and the rotating heat conducting mechanism 11 is provided outside the movement control mechanism 10. The left and right side surfaces of the protection frame 1 are connected to a thermal pad 12, and a sliding frame 13 is slidably connected to the outside of the thermal pad 12. The side of the sliding frame 13 is provided with an explosion-proof pressure relief mechanism 16 that penetrates and is connected to the side of the protection frame 1.

[0043] The fan assembly 4 is used to suck and discharge the air in the protective frame 1, so that the entire control cabinet is placed in a vacuum or thin air environment;

[0044] Specifically, such as Figure 1-3 As shown, a controller 3 is provided on the front of the revolving door 2 , a connecting block 14 is connected to the side of the sliding frame 13 , a sliding rail 15 is slidably connected to the outside of the connecting block 14 , and the sliding rail 15 is fixedly connected to the outside of the protective frame 1 .

[0045] The slide rail 15 cooperates with the connecting block 14 to guide and support the vertical sliding of the sliding frame 13, ensuring that the sliding frame 13 slides stably on the surface of the thermal pad 12;

[0046] Specifically, such as Figure 7-8 As shown, the sliding bearing mechanism 7 includes a moving seat 71 and a bearing plate 72. An electric slider 73 is connected under the moving seat 71. The electric slider 73 slides in the electric guide rail 6. Four buffer springs 74 are fixedly connected to the moving seat 71. The buffer springs 74 are connected under the bearing plate 72. The bearing plate 72 is connected under a damping telescopic rod 75 provided on the moving seat 71. The limiting mechanism 17 is connected to the outside of the moving seat 71 and the bearing plate 72.

[0047] The electric slide rail 15 cooperates with the electric slider 73 to control the movable seat 71 and the carrying plate 72 to move forward and backward, making it convenient to assemble the control cabinet on the carrying plate 72. The buffer spring 74 and the damping telescopic rod 75 can provide shock absorption protection for the carrying plate 72 and the control cabinet.

[0048] Specifically, such as Figure 8-9As shown, the limiting mechanism 17 includes a limiting frame 171 fixedly connected under the supporting plate 72 and a one-way cylinder 172 provided on the movable seat 71, a movable plate 173 is slidably connected in the one-way cylinder 172, a movable rod 174 is fixedly connected to the side of the movable plate 173, and one end of the movable rod 174 located outside the one-way cylinder 172 is fixedly connected to the limiting block 176, the limiting block 176 is slidably connected in the limiting frame 171, and the outer sleeve of the movable rod 174 is provided with a fourth spring 175 connected to the movable plate 173 and the inner wall of the one-way cylinder 172.

[0049] When the limit block 176 is inserted into the limit frame 171, the limit frame 171 and the supporting plate 72 are limited, and the supporting plate 72 and the movable seat 71 cannot move relative to each other. At this time, the control cabinet and the supporting plate 72 cannot perform shaking buffering, and the air pressure in the protective frame 1 is reduced. The extrusion plate 82, the moving rod 174 and the limit block 176 will move away from the limit frame 171, releasing the limit on the limit frame 171 and the supporting plate 72.

[0050] Specifically, such as Figure 4-5 As shown, the extrusion adjustment mechanism 8 includes a connecting frame 81 fixedly connected to the protective frame 1, the inner wall of the connecting frame 81 is slidably connected to the extrusion plate 82, the outside of the extrusion plate 82 is fixedly connected to the cross bar 83, the end of the cross bar 83 located outside the connecting frame 81 is fixedly connected to the contact plate 84, the contact plate 84 is provided on the back of the movable seat 71, the outside of the extrusion plate 82 is fixedly connected to the first spring 85, the first spring 85 is fixedly connected to the inner wall of the connecting frame 81, and the connecting frame 81 is connected to the intermediate tube 9.

[0051] The movable seat 71 will squeeze the contact plate 84 and the extrusion plate 82 to move backward. When the extrusion plate 82 moves, the gas in the first connecting tube 101 is sucked into the connecting frame 81 through the intermediate tube 9. The movement of the contact plate 84 is adjusted by moving the control cabinet in the front and rear directions to realize the adjustment and control of the internal air pressure of the first connecting tube 101.

[0052] Specifically, such as Figure 4-5 As shown, the mobile control mechanism 10 includes a first connecting cylinder 101 fixedly connected to the protective frame 1, a piston plate 102 is slidably connected to the inner wall of the first connecting cylinder 101, a first piston rod 103 is fixedly connected to the outside of the piston plate 102, one end of the first piston rod 103 is connected to the extrusion column 104, the first connecting cylinder 101 is connected to the intermediate tube 9, and the first piston rod 103 passes through and is linearly slidably connected to the side of the first connecting cylinder 101.

[0053] When the air pressure in the first connecting tube 101 decreases, the piston plate 102 and the cross bar 83 can be controlled to move. At this time, the extrusion column 104 moves close to the heat conducting plate 1111 to achieve the control of the extrusion column 104 to adjust the extrusion of the heat conducting plate 1111.

[0054] Specifically, such as Figure 4 and Figure 6 As shown, the rotating heat-conducting mechanism 11 includes a heat-conducting component 111 and a fixed plate 112 connected in the protective frame 1, a second spring 113 is connected to the side of the fixed plate 112, the other end of the second spring 113 is fixedly connected to the heat-conducting component 111, and the heat-conducting component 111 includes five heat-conducting plates 1111, and the side of the heat-conducting plate 1111 close to the side wall of the protective frame 1 is attached to the corresponding position of the thermal pad 12.

[0055] The other side of the heat conducting plate 1111 is arranged outside the control cabinet. The opposite surfaces of the two adjacent heat conducting plates 1111 in the same rotating heat conducting mechanism 11 are provided with a spherical shell 1113. The two spherical shells 1113 are hinged with the same connecting rod 1114. A pin assembly 1112 is hinged through the heat conducting plate 1111, and the pin assembly 1112 is fixedly connected to the inner wall of the protective frame 1.

[0056] The extrusion column 104 pushes the heat conducting plate 1111 to rotate around the pin assembly 1112. At this time, the second spring 113 is squeezed to shorten. At the same time, the heat conducting plate 1111 rotates to contact the surface of the control cabinet, and the connecting head 1612 is assembled and connected to the control cabinet. After the control cabinet moves to the specified position in the protective frame 1, the heat conducting plate 1111 will automatically rotate and contact the control cabinet, realizing the formation of a heat channel between the heat conducting plate 1111, the thermal pad 12 and the control cabinet.

[0057] Specifically, such as Figure 2-3 and Figure 10 As shown, the explosion-proof pressure relief mechanism 16 includes a rotating rod 1601 and a second connecting tube 1602 that is connected to the side wall of the protective frame 1, a damping pressure plate 1604 is slidably connected in the second connecting tube 1602, and a second piston rod 1605 is connected to the side of the damping pressure plate 1604. The second piston rod 1605 is connected to a movable seat 1606 at one end outside the second connecting tube 1602, and connecting pins 1603 are hinged on the side of the rotating rod 1601 near both ends. The connecting pin 1603 near the side of the sliding frame 13 is hinged to the outside of the sliding frame 13, and the other connecting pin 1603 is hinged to the outside of the movable seat 1606.

[0058] The outer sleeve of the second piston rod 1605 is provided with a third spring 1607 fixedly connected to the damping pressure plate 1604 and the second connecting cylinder 1602. The second connecting cylinder 1602 is connected to the outside of the pressure relief valve 1609, and the pressure relief valve 1609 is located outside the protective frame 1. An air hole 1608 is provided on the side of the second connecting cylinder 1602. The outside of the second connecting cylinder 1602 is connected to a one-way valve 1610 for air intake. The end of the one-way valve 1610 is connected to a bellows 1611, and the other end of the bellows 1611 is connected to a connector 1612 installed outside the control cabinet.

[0059] The expanded gas inside the control cabinet will flow directly into the second connecting tube 1602 through the connecting head 1612, the bellows 1611 and the one-way valve 1610. The second connecting tube 1602 increases the space where the gas can flow during the explosion, and the flowing gas will push the damping pressure plate 1604 to move in the second connecting tube 1602. The movement of the damping pressure plate 1604 is controlled by the second piston rod 1605 and the connecting pin shaft 1603 to control the movement of the rotating rod 1601, thereby controlling the downward movement of the sliding frame 13 and increasing the energy consumed by the gas flow. The pressure relief valve 1609 can discharge the air pressure that continues to increase after the pressure reduction and energy consumption.

[0060] Working principle, when using:

[0061] First, the electric guide rail 6 is used to control the electric slider 73 and the moving seat 71 to move forward, and the control cabinet is installed on the bearing plate 72. Then, the electric guide rail 6 is controlled to drive the control cabinet to move into the protective frame 1. The moving seat 71 squeezes the contact plate 84 and the squeezing plate 82 to move backward. While the squeezing plate 82 moves, the gas in the first connecting cylinder 101 is sucked into the connecting frame 81 through the intermediate pipe 9, so as to control the piston plate 102, the cross bar 83 and the squeezing column 104 to move forward. The squeezing column 104 pushes the heat conducting plate 1111 to rotate around the pin assembly 1112. At this time, the second spring 1 is squeezed. 13 is shortened, and at the same time, the heat conducting plate 1111 is rotated to contact the surface of the control cabinet, and the connector 1612 is assembled and connected to the control cabinet. Then, the revolving door 2 is closed, and the fan assembly 4 is controlled to operate to suck the air in the protective frame 1, so that the air inside the protective frame 1 is in a relatively thin or vacuum state. As the air pressure in the protective frame 1 decreases, the extrusion plate 82, the moving rod 174 and the limit block 176 will move away from the limit frame 171, releasing the limit on the limit frame 171 and the supporting plate 72. At this time, the control cabinet and the supporting plate 72 can be buffered and shock-absorbing by the buffer spring 74 and the damping telescopic rod 75;

[0062] The heat generated during the operation of the control cabinet is conducted to the outside of the protective frame 1 through the heat conducting plate 1111 and the heat conducting pad 12, and the vacuum state inside the control cabinet blocks the noise during the operation of the control cabinet, thereby achieving a noise reduction effect. When obvious high temperature or explosion occurs inside the control cabinet, the expanded gas inside the control cabinet will directly flow into the second connecting tube 1602 through the connecting head 1612, the bellows 1611 and the one-way valve 1610. The second connecting tube 1602 increases the space where the gas can flow during the explosion, and the flowing gas will push the damping pressure plate 1604 to move in the second connecting tube 1602. The movement of the damping pressure plate 1604 is controlled by the second piston rod 1605 and the connecting pin shaft 1603 to control the movement of the rotating rod 1601, thereby controlling the downward movement of the sliding frame 13, increasing the energy consumed by the gas flow, and achieving the purpose of decompression and rapid energy consumption in the explosion situation, and the sliding frame 13 cleans the surface of the heat conducting pad 12.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
