Description

Technical Field

[0001] This invention belongs to the field of power facility installation technology, and specifically relates to an installation device for power facilities. Background Technology

[0002] Power facilities include power supply, transmission, and receiving equipment. Cables are a type of power facility, commonly used for laying various power grids. Cable trays are required during installation. Cable trays are divided into trough type, tray type, ladder type, and mesh type structures, and are composed of supports, brackets, and installation accessories. Cable trays inside buildings can be erected independently or laid on various building and pipe rack supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized before being installed on exposed cable trays outside buildings.

[0003] Currently, existing industrial equipment cables need to transmit power according to the production cycle of the industrial equipment. During use, the transmission of current within the cable will cause the cable to heat up. After heating up, the cable will expand and contract, causing wear between the cable and the clamps fixing the cable, which will shorten the service life of the cable. In addition, heat will accumulate in the cable tray, which will affect the power transmission efficiency of the cable and accelerate the aging of the cable. Based on this, an installation device for power facilities is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a reasonably designed installation device for power facilities in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An installation device for power facilities includes a tray, a cover plate inserted into the top of the tray, and heat dissipation vents on both sides of the tray. It also includes: A cable fixing mechanism is fixedly connected in the tray for fixing the cable. The cable fixing mechanism includes an upper clamp and a lower clamp. Multiple balls are rolledly connected to the opposite sides of the upper clamp and the lower clamp. The multiple balls are in contact with the outer surface of the cable. Rotate the temperature sensing mechanism connected to the tray. The temperature sensing mechanism opens the heat dissipation vent when the cable is working and automatically closes the heat dissipation vent when the cable stops working. A shielding mechanism fixedly connected to a temperature sensing mechanism, the shielding mechanism being used to shield electromagnetic interference when the cable is in operation.

[0006] As a further optimization of the present invention, the temperature sensing mechanism includes a sealing door fixedly connected to the tray by a hinge, a temperature sensing plate fixedly connected to the adjacent side of the sealing door, the temperature sensing plate being hollow, a downwardly inclined through groove on the sealing door communicating with the interior of the temperature sensing plate, a plurality of air blowing ports on the top of the temperature sensing plate, and the temperature sensing plate being made of shape memory metal.

[0007] As a further optimization of the present invention, the sealing door is installed inside the heat dissipation vent, and the bottom of the heat dissipation vent is inclined.

[0008] As a further optimization of the present invention, the cable fixing mechanism further includes a support plate fixedly connected to the tray, a plurality of wire clamps fixedly connected to the support plate, and damping rods fixedly connected to the upper surface of the upper clamp and the lower surface of the lower clamp, the damping rods being fixedly connected to the inner surface of the wire clamps.

[0009] As a further optimization of the present invention, a buffer spring is fixedly connected to the upper surface of the upper clamping plate and the lower surface of the lower clamping plate, and the buffer spring is fixedly connected to the inner surface of the clamp.

[0010] As a further optimization of the present invention, the shielding mechanism includes a connecting plate fixedly connected to the bottom of the temperature sensing plate, a shielding plate fixedly connected to the end of the connecting plate, a plurality of filter holes being provided in the upper middle part of the shielding plate, and a groove being provided in the top of the shielding plate.

[0011] As a further optimization of the present invention, the shielding plate is attached to the inner surface of the tray, the shielding plate is positioned directly opposite the heat dissipation vent, and the groove is positioned directly opposite the temperature sensing plate.

[0012] As a further optimization of the present invention, a ventilation chamber is fixedly connected to the inner bottom of the tray, the ventilation chamber has a through hole, the shielding plate is slidably connected to the ventilation chamber in a sealed manner, and a drain hole is provided at the bottom of the tray, the drain hole communicating with the interior of the ventilation chamber.

[0013] As a further optimization of the present invention, ventilation slots are provided on both sides of the tray, and the ventilation slots are connected to the interior of the ventilation chamber.

[0014] The beneficial effects of this invention are as follows: 1. The present invention, through the setting of the cable fixing mechanism, allows the spacing between the upper and lower clamps to change with the diameter of the cable when the cable undergoes radial expansion and contraction, thanks to the damping rod and buffer spring. When the cable heats up and undergoes axial expansion and contraction, the ball bearings reduce the friction between the cable and the clamp during axial expansion and contraction, thus providing good protection for the cable and extending its service life.

[0015] 2. Through the setting of the temperature sensing mechanism, when the cable is working, the temperature sensing plate will gradually change from a bent state to a straight state under the action of temperature. During this process, the temperature sensing plate will push the sealing door to open outward, so that the heat dissipation vent is opened until the top of the temperature sensing plate contacts the cable. At this time, the outside air will enter the hollow temperature sensing plate through the through groove, thereby realizing the heat dissipation operation of the cable. At the same time, the temperature sensing plate will conduct the temperature of the cable outward, further improving the heat dissipation efficiency of the cable, thereby ensuring the stability of the cable's operation and extending the service life of the cable.

[0016] 3. The present invention, through the setting of the temperature sensing plate, provides support for the cable by contacting the bottom of the cable. When the cable is transmitting current, it further buffers and absorbs the vibration of the cable. In addition, when the cable vibrates, the temperature sensing plate will move up and down, thereby causing the sealing doors on both sides to swing, further accelerating the airflow speed in the internal space of the tray and cover, thereby further improving the heat dissipation efficiency of the cable, reducing the impact of temperature on the cable, and thus reducing the probability of cable aging and wear.

[0017] 4. Through the shielding mechanism, this invention ensures that during cable operation, as the sealing door opens, the temperature sensing plate gradually becomes flat, pulling the connecting plate upwards and causing the shielding plate to move upwards as well. When the temperature sensing plate is flat, the filter holes of the shielding plate are completely positioned at the heat dissipation vent. At this point, the shielding plate is located on both sides of the cable, achieving shielding against external electromagnetic interference and filtering the air entering the heat dissipation vent, reducing dust interference with the cable, thus further protecting the cable and extending its service life.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, an installation device for power facilities includes a tray 1, a cover plate 2 inserted into the top of the tray 1, and heat dissipation vents 3 on both sides of the tray 1. The bottom of the heat dissipation vents 3 is inclined. A cable fixing mechanism 4 for fixing cables is fixedly connected inside the tray 1. The cable fixing mechanism 4 includes an upper clamping plate 44 and a lower clamping plate 46. Multiple balls 47 are rolled and connected to opposite sides of the upper clamping plate 44 and the lower clamping plate 46. The multiple balls 47 are in contact with the outer surface of the cable. A support plate 41 is fixedly connected inside the tray 1. Multiple wire clamps 42 are fixedly connected to the support plate 41. A damping rod 43 is fixedly connected to the upper surface of the upper clamping plate 44 and the lower surface of the lower clamping plate 46. The damping rod 43 is fixedly connected to the inner surface of the wire clamp 42. A buffer spring 45 is fixedly connected to the upper surface of the upper clamping plate 44 and the lower surface of the lower clamping plate 46. The buffer spring 45 is fixedly connected to the inner surface of the wire clamp 42.

[0022] When installing the cable, open the cover plate 2, then open the clamp 42 and place the cable on the lower clamp 46. Then close the clamp 42. At this time, the upper clamp 44 and lower clamp 46 clamp the cable securely with ball bearings 47. When current flows through the cable, the cable will heat up, causing it to expand and contract. The damping rod 43 and buffer spring 45 allow the distance between the upper clamp 44 and lower clamp 46 to change with the cable diameter. When the cable expands and contracts axially due to heat, the ball bearings 47 reduce friction between the cable and the clamp 42, providing good protection and extending the cable's service life. Furthermore, during the use of this installation device, if the cable or the device vibrates, the damping rod 43 and buffer spring 45 absorb and buffer the vibration, further protecting the cable and extending their service life.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, a temperature sensing mechanism 5 is rotatably connected to the tray 1. The temperature sensing mechanism 5 opens the heat dissipation vent 3 when the cable is working and automatically closes the heat dissipation vent 3 when the cable stops working. The temperature sensing mechanism 5 includes a sealing door 52 connected to the tray 1 by a hinge. The sealing door 52 is installed inside the heat dissipation vent 3. A temperature sensing plate 51 is fixedly connected to the adjacent side of the sealing door 52. The temperature sensing plate 51 is made of shape memory metal. The temperature sensing plate 51 is arc-shaped at room temperature and is hollow. The sealing door 52 has a downward inclined through groove 53 that communicates with the inside of the temperature sensing plate 51. The top of the temperature sensing plate 51 has multiple air blowing ports 54.

[0024] When current flows through the cable, the cable heats up under the influence of the current, which in turn heats the internal space of tray 1 and cover 2. At this time, the temperature-sensing plate 51, made of shape memory metal, will gradually change from a bent state to a straight state under the influence of temperature. During this process, the temperature-sensing plate 51 will push the sealing door 52 to open outward, opening the heat dissipation vent 3 until the top of the temperature-sensing plate 51 contacts the cable. At this time, outside air will enter the hollow temperature-sensing plate 51 through the through groove 53, thereby achieving heat dissipation for the cable. At the same time, the temperature-sensing plate 51 will conduct the heat of the cable outward, further improving the heat dissipation efficiency of the cable. This ensures the stability of the cable's operation and extends its service life. In addition, since the temperature sensing plate 51 is in contact with the bottom of the cable, it provides support for the cable. When the cable is transmitting current, it further buffers and absorbs the vibration of the cable. Furthermore, when the cable vibrates, the temperature sensing plate 51 will move up and down, which will cause the sealing doors 52 on both sides to swing, further accelerating the airflow speed in the internal space of the tray 1 and the cover plate 2. This further improves the heat dissipation efficiency of the cable, reduces the impact of temperature on the cable, and thus reduces the probability of cable aging and wear.

[0025] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, a shielding mechanism 6 is fixedly connected to the temperature sensing mechanism 5. The shielding mechanism 6 is used to shield electromagnetic interference when the cable is working. The shielding mechanism 6 includes a connecting plate 61 fixedly connected to the bottom of the temperature sensing plate 51. The connecting plate 61 is fixedly connected to the middle position of the temperature sensing plate 51. A shielding plate 62 is fixedly connected to the end of the connecting plate 61. The shielding plate 62 is attached to the inner surface of the tray 1 and is positioned directly opposite the heat dissipation vent 3. Multiple filter holes 63 are provided in the upper middle part of the shielding plate 62, and a groove 64 is provided on the top of the shielding plate 62. The groove 64 is positioned directly opposite the heat dissipation vent 3. A temperature sensing plate 51 is provided. A ventilation chamber 65 is fixedly connected to the inner bottom of the tray 1. Ventilation slots 68 are provided on both sides of the tray 1. The ventilation slots 68 are connected to the interior of the ventilation chamber 65. A through hole 66 is provided on the ventilation chamber 65. A one-way valve is installed in the through hole 66, so that the ventilation chamber 65 can only draw gas through the through hole 66. The shielding plate 62 is L-shaped. The bottom of the shielding plate 62 is slidably connected to the ventilation chamber 65. A drain hole 67 is provided at the bottom of the tray 1. The drain hole 67 is connected to the interior of the ventilation chamber 65. A one-way valve is installed in each drain hole 67.

[0026] During cable operation, as the sealing door 52 opens, the temperature sensing plate 51 gradually becomes flat, which in turn pulls the connecting plate 61 upward, causing the shielding plate 62 to move upward. When the temperature sensing plate 51 is flat, the filter holes 63 of the shielding plate 62 will be completely located at the heat dissipation port 3. At this time, the shielding plate 62 is located on both sides of the cable, which on the one hand shields against external electromagnetic interference, and on the other hand filters the air entering the heat dissipation port 3, reducing the interference of dust on the cable, thereby achieving further protection of the cable and extending its service life. At the same time, the upward movement of the shielding plate 62 will cause the ventilation chamber 65 to draw gas from the inside of the tray 1 through the through hole 66, thereby accelerating the rate at which the outside airflow enters the tray 1 and further improving the cooling efficiency of the cable. At the same time, the bottom of the shielding plate 62 will be located at the position of the ventilation groove 68, so that the outside can communicate with the inside of the ventilation chamber 65 through the ventilation groove 68. At this time, the air inside the tray 1 will circulate through the through hole 66, further realizing the heat dissipation of the tray 1, thereby realizing the further heat dissipation operation of the cable. When the cable stops working, as the temperature inside the tray 1 and cover 2 gradually recovers, the temperature sensing plate 51 will gradually return to its initial state, which will push the connecting plate 61 to move downward, causing the shielding plate 62 to move downward, compressing the internal space of the ventilation chamber 65, and allowing the gas inside the ventilation chamber 65 to be discharged through the drain hole 67. In addition, when the shielding plate 62 moves downward, the heat dissipation vent 3, which is set at an angle at the bottom, will clean the filter holes 63 of the shielding plate 62, remove the dust adhering to the filter holes 63, and facilitate good air filtration for the next use.

[0027] The specific working principle of this invention is as follows: When installing the cable, open the cover plate 2, then open the clamp 42 and place the cable on the lower clamp 46. Then close the clamp 42. At this time, the upper clamp 44 and lower clamp 46 clamp the cable securely with ball bearings 47. When current flows through the cable, the cable will heat up, causing it to expand and contract. The damping rod 43 and buffer spring 45 allow the distance between the upper clamp 44 and lower clamp 46 to change with the cable diameter. When the cable expands and contracts axially due to heat, the ball bearings 47 reduce friction between the cable and the clamp 42, providing good protection and extending the cable's service life. Furthermore, during the use of this installation device, when the cable or the device vibrates, the damping rod 43 and buffer spring 45 absorb and buffer the vibration, further protecting the cable and extending their service life. When current flows through the cable, the cable heats up under the influence of the current, which in turn heats the internal space of tray 1 and cover 2. At this time, the temperature-sensing plate 51, made of shape memory metal, will gradually change from a bent state to a straight state under the influence of temperature. During this process, the temperature-sensing plate 51 will push the sealing door 52 to open outward, opening the heat dissipation vent 3 until the top of the temperature-sensing plate 51 contacts the cable. At this time, outside air will enter the hollow temperature-sensing plate 51 through the through groove 53, thereby achieving heat dissipation for the cable. At the same time, the temperature-sensing plate 51 will conduct the heat of the cable outward, further improving the heat dissipation efficiency of the cable. This ensures the stability of the cable's operation and extends its service life. In addition, since the temperature sensing plate 51 is in contact with the bottom of the cable, it will provide support for the cable. When the cable is transmitting current, it will further buffer and absorb the vibration of the cable. Furthermore, when the cable vibrates, the temperature sensing plate 51 will move up and down, which will cause the sealing doors 52 on both sides to swing, further accelerating the airflow speed in the internal space of the tray 1 and the cover plate 2, thereby further improving the heat dissipation efficiency of the cable, reducing the impact of temperature on the cable, and thus reducing the probability of cable aging and wear. During cable operation, as the sealing door 52 opens, the temperature sensing plate 51 gradually becomes flat, which in turn pulls the connecting plate 61 upward, causing the shielding plate 62 to move upward. When the temperature sensing plate 51 is flat, the filter holes 63 of the shielding plate 62 will be completely located at the heat dissipation port 3. At this time, the shielding plate 62 is located on both sides of the cable, which on the one hand shields against external electromagnetic interference, and on the other hand filters the air entering the heat dissipation port 3, reducing the interference of dust on the cable, thereby achieving further protection of the cable and extending its service life. At the same time, the upward movement of the shielding plate 62 will cause the ventilation chamber 65 to draw gas from the inside of the tray 1 through the through hole 66, thereby accelerating the rate at which the outside airflow enters the tray 1 and further improving the cooling efficiency of the cable. At the same time, the bottom of the shielding plate 62 will be located at the position of the ventilation groove 68, so that the outside can communicate with the inside of the ventilation chamber 65 through the ventilation groove 68. At this time, the air inside the tray 1 will circulate through the through hole 66, further realizing the heat dissipation of the tray 1, thereby realizing the further heat dissipation operation of the cable. When the sealing door 52 swings, the ventilation chamber 65 will intermittently exhaust and extract air through the through hole 66, thus accelerating the circulation of outside air. When the cable stops working, as the temperature inside the tray 1 and cover 2 gradually recovers, the temperature sensing plate 51 will gradually return to its initial state, which will push the connecting plate 61 to move downward, causing the shielding plate 62 to move downward, compressing the internal space of the ventilation chamber 65, and allowing the gas inside the ventilation chamber 65 to be discharged through the drain hole 67. In addition, when the shielding plate 62 moves downward, the heat dissipation vent 3, which is inclined at the bottom, will clean the filter holes 63 of the shielding plate 62, remove the dust adhering to the filter holes 63, and facilitate good air filtration for the next use.

[0028] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
