Description

Technical Field

[0001] The utility model belongs to the technical field of resistance boxes, and particularly relates to a water-proof resistance box with an insulating component. Background Art

[0002] At present, in order to ensure the heat dissipation effect of the resistance box, heat dissipation holes are usually opened on its outer shell to ensure the air circulation inside the shell and achieve the purpose of heat dissipation. At the same time, these heat dissipation holes will affect its waterproof performance, and external water is easy to flow into the inside of the outer shell through the heat dissipation holes, causing faults such as short circuits of the resistors. And completely enclosing the outer shell of the resistance box, although it can improve the water-proof effect, will affect the heat dissipation effect of the resistance box.

[0003] Therefore, it is necessary to design a water-proof resistance box with an insulating component that can improve the water-proof effect while ensuring that the heat inside the resistance box can be dissipated outward to solve the current technical problems. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the utility model provides a water-proof resistance box with an insulating component that can improve the water-proof effect while ensuring that the heat inside the resistance box can be dissipated outward.

[0005] The technical solution of the utility model is as follows: a water-proof resistance box with an insulating component, including an integrated bottom box, an opening is provided at the top of the bottom box, a cover plate is detachably and fixedly arranged on the opening, a terminal is arranged at the top of the bottom box on one side of the opening, an air inlet hood is arranged at one end of the bottom box, an air outlet hood is arranged at the other end of the bottom box, a heat dissipation fan is arranged inside the air outlet hood, a partition is arranged inside the bottom box, an air inlet cavity is formed between the partition and the inner bottom of the bottom box, the air inlet cavity is communicated with the air inlet hood through an air inlet channel, an air outlet is opened on the partition, and a wire-wound resistor is arranged at the top of the partition.

[0006] A slot is arranged at the end of the air inlet hood, and the air inlet moisture absorption component is detachably inserted inside the slot.

[0007] The air inlet moisture absorption component has a support frame, a moisture absorption chamber and an air inlet are alternately arranged inside the support frame, a desiccant is arranged inside the moisture absorption chamber, and moisture absorption holes are evenly opened on both sides of the moisture absorption chamber corresponding to the air inlet.

[0008] Insulating components are fixedly arranged at both ends of the wire-wound resistor, the insulating components are "L"-shaped plates made of bakelite, and the bottom ends of the insulating components are assembled and fixed on the top of the partition.

[0009] A protective net is arranged at the end of the air outlet hood facing away from the bottom box.

[0013] Advantages of the present utility model:

[0014] (1) In the present utility model, there are no gaps around and at the bottom of the integrated bottom box, which can effectively prevent water from seeping into the inside of the bottom box from the top during use, causing faults such as internal short circuits.

[0015] (2) The cooling fan drives the generation of air flow inside the bottom box. External air enters the inside of the air inlet cavity from the air inlet hood and the air inlet duct, and then flows upward from the air outlet above the air inlet cavity to the air outlet hood and is discharged outward.

[0026] As Figures 1 to 5 shown, a water-proof resistor box with an insulation component includes an integral bottom box 1. An opening is provided at the top of the bottom box 1, and a cover plate 2 is detachably and fixedly arranged on the opening. A wiring terminal 3 is arranged at the top of the bottom box on one side of the opening. An air inlet hood 11 is arranged at one end of the bottom box 1, and an air outlet hood 12 is arranged at the other end of the bottom box 1. A heat dissipation fan 6 is arranged inside the air outlet hood 12. A partition 15 is arranged inside the bottom box 1. An air inlet cavity 17 is formed between the partition 15 and the inner bottom of the bottom box 1. The air inlet cavity 17 is communicated with the air inlet hood 11 through an air inlet channel 16. An air outlet 151 is formed on the partition 15. A wound resistor 5 is arranged on the top of the partition 15. In this embodiment, there are no gaps around and at the bottom of the integral bottom box 1, and during use, it can effectively prevent water from seeping into the inside of the bottom box 1 from the top, causing internal short circuit and other faults. The heat dissipation fan 6 drives the generation of air flow inside the bottom box 1. External air enters the inside of the air inlet cavity 17 from the air inlet hood 11 and the air inlet channel 16, and then flows upward through the air outlet 151 above the air inlet cavity 17 to the air outlet hood 12 and is discharged outward. The air flow inside the bottom box 1 can dissipate the heat generated by the resistor during use, preventing it from being damaged due to excessive temperature. The cover plate 2 is detachably arranged on the top of the bottom box 1, and removing the cover plate 2 facilitates the maintenance of the internal circuits and resistors of the bottom box 1.

[0027] In some embodiments, as Figure 2As shown, a slot 13 is provided at the end of the air inlet hood 11, and the air inlet and moisture absorption component 4 is detachably inserted into the inside of the slot 13. The air inlet and moisture absorption component 4 can dry the air entering the bottom box 1 from the air inlet hood 11, reducing the entry of water vapor into the bottom box 1.

[0028] In some embodiments, as Figure 6 and 7 shown, the air inlet and moisture absorption component 4 has a support frame 42. Moisture absorption chambers 43 and air inlets 41 are alternately arranged inside the support frame 42. A desiccant 44 is arranged inside the moisture absorption chamber 43. Moisture absorption holes 43 are evenly formed on both sides of the moisture absorption chamber 43 corresponding to the air inlets 41. When the air outside the bottom box 1 enters the inside of the air inlet hood 11 through the air inlets 41, the desiccant 44 inside the moisture absorption chamber 43 absorbs part of the water vapor in the air passing through the air inlets 41, so as to achieve the purpose of reducing the entry of water vapor into the bottom box 1.

[0029] In some embodiments, insulating components 51 are fixedly arranged at both ends of the wire-wound resistor 5. The insulating components 51 are "L"-shaped plate bodies made of bakelite. The bottom ends of the insulating components 51 are assembled and fixed to the top of the partition plate 15; the two insulating components 51 are assembled and fixed to both ends of the wire-wound resistor 5 through a screw and nut assembly arranged along the axis of the wire-wound resistor. The connection manner between the insulating component 51 and the wire-wound resistor 5 is a common connection manner in the prior art, so the specific connection manner will not be described in detail.

[0030] In some embodiments, a protective net 14 is provided at one end of the air outlet hood 12 facing away from the bottom box 1. The protective net 14 is a metal net, and the four sides of the metal net 14 are welded to the end of the air outlet hood 12. The metal net 14 can prevent animals such as mice from entering the bottom box 1 through the air outlet hood 12.

[0031] In some embodiments, the openings of the air inlet hood 11 and the air outlet hood 12 face downward to prevent rainwater from entering the bottom box 1 through the air inlet hood 11 and the air outlet hood 12.

[0032] In some embodiments, the air outlet 151 corresponds to the wire-wound resistor 5, so that the air flow directly acts on the wire-wound resistor 5.

[0033] In some embodiments, a sealing ring matching the cover plate 2 is provided on the opening, and the cover plate 2 is detachably and fixedly connected to the opening; specifically, the cover plate 2 is assembled and fixed to the opening through bolts.

In order to avoid obscuring the concept of the present invention, some details well known in the art have not been described. Those skilled in the art can clearly understand how to implement the technical solutions disclosed here based on the above description.

[0035] The above-described embodiments only represent some implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
