Description

Technical Field

[0001] The utility model relates to the technical field of bridge heat dissipation, and particularly relates to a bridge heat dissipation and ventilation device. Background Art

[0002] In a heat treatment process workshop, the ambient temperature is generally affected, especially for metal objects with easy heat conduction. At present, iron bridges are mostly used for the layout and protection of cables. However, most power cables will generate heat during use, and it is normal for the cable load temperature to be between 30-50°C. Although the allowable temperature values of different types of cables are different, for example, cross-linked polyethylene insulated cables can withstand a long-term temperature of 90°C, and polyvinyl chloride insulated cables can only withstand a long-term temperature of 70°C. At present, most of the cables used are polyvinyl chloride insulated cables, and the surface temperature during use is nearly 90°C. Although the iron bridge used for layout or protection is conducive to cable heat dissipation to a certain extent, it is easy to cause the heat dissipation ability of the bridge to weaken or even lose the heat dissipation ability in a high-temperature environment, resulting in problems such as accelerated aging of cables in a high-temperature environment, thus affecting the service life of the cables or having certain safety hazards.

[0003] Therefore, it is very necessary to invent a bridge heat dissipation and ventilation device to solve the above problems. Content of the Utility Model

[0004] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a bridge heat dissipation and ventilation device, which solves the problems in the prior art that although the iron bridge used for layout or protection is conducive to cable heat dissipation to a certain extent, it is easy to cause the heat dissipation ability of the bridge to weaken or even lose the heat dissipation ability in a high-temperature environment, resulting in problems such as accelerated aging of cables in a high-temperature environment, thus affecting the service life of the cables or having certain safety hazards.

[0005] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0006] A bridge heat dissipation and ventilation device includes two bridges with open tops and a U-shaped connecting frame detachably connected between the left sides of the two bridges. A transfer air duct that can transport cold air for heat dissipation inward by an external fan is detachably clamped at the top of the U-shaped connecting frame. Both ends of the transfer air duct are detachably connected with L-shaped transport air ducts, and the flow ventilation volume of the shorter side branch of the L-shaped transport air duct can be controlled. The longer side branch of the L-shaped transport air duct is adapted to the length of the bridge and is located directly above the open end of the bridge. A plurality of air outlet ducts that can discharge cold air for heat dissipation into the bridge are equidistantly arranged on the bottom side of the peripheral side wall of the L-shaped transport air duct.

[0007] As a preferred embodiment of the present utility model, an air inlet pipe is connected to the middle part on the left side of the peripheral side wall of the transfer air duct. The other end of the air inlet pipe is connected with an external flange, and the external flange can be detachably connected to the air outlet of an external fan.

[0008] As a preferred embodiment of the present utility model, main flanges are connected to both ends of the transfer air duct. A side flange is connected to the end of the shorter side branch of the L-shaped transportation air duct. The main flange and the side flange are detachably connected.

[0009] As a preferred embodiment of the present utility model, a first regulating valve for controlling the flow ventilation volume is installed in the air inlet pipe, and a second regulating valve for controlling the flow ventilation volume is installed in the shorter side branch of the L-shaped transportation air duct.

[0010] As a preferred embodiment of the present utility model, first support frames can be detachably installed at symmetrical positions at the top of the U-shaped connecting frame, and the transfer air duct is detachably clamped between the two first support frames.

[0011] As a preferred embodiment of the present utility model, a second support frame is detachably clamped to the part of the L-shaped transportation air duct located between the two air outlet pipes. Both ends of the second support frame extend to form clamping plates, and an insertion post is connected to the bottom end of the clamping plate. The bottom end of the second support frame abuts against the top surface of the bridge, and a resisting plate is connected to the position of each clamping plate on both outer side walls of the bridge. The insertion post is detachably inserted longitudinally into the resisting plate.

[0012] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0013] In the present utility model, the cooling cold air generated by the external fan is first transmitted into the transfer air duct, and then transported through the L-shaped transportation air duct to the position directly above the corresponding bridge. Furthermore, the cold air is conveyed to the bridge at different positions through the air outlet pipes at multiple positions, so as to perform cold air heat dissipation ventilation treatment on the cables arranged inside the bridge at different positions. Finally, on the premise of not affecting the overall ambient temperature, the cold air heat dissipation ventilation treatment is carried out on different positions of the bridge through the air outlet pipes at multiple positions, which can not only achieve local cooling or heat dissipation, but also perform overall heat dissipation cooling on the cables in the bridge, avoiding cable damage caused by excessive temperature in the bridge.

Detailed Implementation Manner

[0019] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0020] The present utility model provides a Figures 1 - 3 bridge heat dissipation and ventilation device as shown, including two bridges 1 with open ends at the top and a U-shaped connecting frame 2 detachably connected between the left sides of the two bridges 1. A transfer air duct 3 that can transport cooling air inward by an external fan is detachably clamped at the top of the U-shaped connecting frame 2. Both ends of the transfer air duct 3 are detachably connected with L-shaped transportation air ducts 5, and the shorter side branch of the L-shaped transportation air duct 5 can control its air flow rate. The longer side branch of the L-shaped transportation air duct 5 is adapted to the length of the bridge 1 and is located directly above the open end of the bridge 1. A plurality of air outlet ducts 6 for discharging cooling air into the bridge 1 are equidistantly arranged on the bottom side of the circumferential side wall of the L-shaped transportation air duct 5. In the actual application process, covers can be added to the tops of the two bridges 1 to close the open top end of the bridge 1, and through slots are opened on the covers, so that the air outlet ducts 6 on the bottom side of the circumferential side wall of each L-shaped transportation air duct 5 penetrate through the through slots and extend into the bridge 1. The specific application scenario depends on the actual usage situation.

[0021] In the middle of the left side of the circumferential side wall of the transfer air duct 3, an air inlet duct 4 is connected, and the other end of the air inlet duct 4 is connected with an external flange 16. The external flange 16 can be detachably connected with the air outlet of the external fan. The air inlet duct 4 is detachably connected with the external fan through the external flange 16, so as to transmit the cooling air generated by the external fan into the transfer air duct 3 through the air inlet duct 4, thus facilitating subsequent transportation and transfer.

[0022] Main flanges 9 are connected to both ends of the transfer air duct 3, and side flanges 10 are connected to the ends of the shorter side branches of the L-shaped transportation air ducts 5. The main flanges 9 and the side flanges 10 are detachably connected. Through the connection method of the main flanges 9 and the side flanges 10, it is convenient to complete the installation and disassembly of the transfer air duct 3 and the L-shaped transportation air duct 5.

[0023] A first regulating valve 7 for controlling the flowing ventilation volume is installed in the air inlet pipe 4, and a second regulating valve 8 for controlling the flowing ventilation volume is installed in the shorter side branch of the L-shaped transportation air pipe 5. The flowing ventilation volumes of the transfer air pipe 3 and the L-shaped transportation air pipe 5 are respectively adjusted through the first regulating valve 7 and the second regulating valve 8, so as to facilitate the control of the cooling air volume.

[0024] First support frames 11 are detachably installed at symmetric positions at the top end of the U-shaped connecting frame 2. The transfer air pipe 3 is detachably clamped between the two first support frames 11. The first support frames 11 can fix the position of the transfer air pipe 3 at the top end of the U-shaped connecting frame 2 and facilitate the disassembly of the transfer air pipe 3 at the same time.

[0025] Portions of the L-shaped transportation air pipe 5 located between the two air outlet pipes 6 are detachably clamped with second support frames 12. Clamping plates 13 are formed by extending both ends of the second support frames 12. A plug post 14 is connected to the bottom end of the clamping plate 13. The bottom end of the second support frame 12 abuts against the top surface of the bridge frame 1, and a resisting plate 15 is connected to each position on the outer side walls of both sides of the bridge frame 1 adapted to each clamping plate 13. The plug post 14 is detachably inserted longitudinally into the resisting plate 15. The top end of the second support frame 12 abuts against the top end of the bridge frame 1, so as to facilitate the L-shaped transportation air pipe 5 to be limited directly above the bridge frame 1, and the insertion of the plug post 14 into the resisting plate 15 can completely limit the position of the L-shaped transportation air pipe 5 directly above the bridge frame 1.

[0026] In the present utility model, the cooling air generated by the external fan is first transmitted into the transfer air pipe 3, and then transported through the L-shaped transportation air pipe 5 to directly above the corresponding position of the bridge frame 1, and then the bridge frame 1 is subjected to cold air delivery through the air outlet pipes 6 at multiple positions at different positions of the bridge frame 1, so as to perform cold air heat dissipation ventilation treatment on the cables arranged inside the bridge frame 1 at different positions of the bridge frame 1. Finally, on the premise of not affecting the overall environmental temperature, the cold air heat dissipation ventilation treatment is performed on different positions of the bridge frame 1 through the air outlet pipes 6 at multiple positions. It can not only achieve local cooling or heat dissipation, but also perform overall heat dissipation cooling on the cables in the bridge frame 1, and avoid cable damage caused by too high temperature in the bridge frame 1.

[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
