[0002] A large number of electrical devices are used in smart agriculture, such as irrigation systems, greenhouse control systems, climate monitoring equipment, etc. These devices are usually installed in complex electrical networks, which may cause certain leakage risks. The leakage protector can monitor the leakage in the circuit in real time. Once leakage is detected, it will quickly cut off the power supply to prevent electrical fires and electric shock accidents, thereby protecting the safety of equipment and personnel.

[0003] In the prior art, the leakage protector is generally installed in the meter box. In the agricultural production environment, in order to facilitate the operation and maintenance of the meter box, the meter box is generally installed in an outdoor environment close to the production site. After the meter box is installed in a sunny outdoor environment, the following effects will occur: Since the meter box is in an outdoor environment with sufficient light, the internal temperature of the meter box that is exposed to the sun for a long time is higher in summer than that of the meter box installed indoors; when the leakage protector is in a high temperature installation environment for a long time, its equipment performance and operational safety are adversely affected, which not only affects the normal operation of the smart agricultural system, but also has an adverse impact on the safety of the entire production system.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0032] Embodiment 1:

[0033] like Figure 1—4 shows: an auxiliary mounting frame for a leakage protection switch, comprising an electrical rail 1, on which a leakage protection switch 6 is mounted, and on the inner side of the electrical rail 1 a heat pipe heat dissipation assembly 2 is mounted, and the heat pipe heat dissipation assembly 2 comprises a heat pipe 21, and the heat pipe 21 is inserted into the electrical rail 1 and a heat dissipation fin 22, and the heat dissipation fin 22 is mounted on the side of a fixing plate 23, and the fixing plate 23 is mounted on the inner side of the electrical rail 1, and an air hole 24 is opened on the fixing plate 23, and one end of the cavity formed between the fixing plate 23 and the electrical rail 1 is blinded and the other end is connected to a connector 3, and the connector 3 is connected to one end of an air pipe 4, and the other end of the air pipe 4 The exhaust assembly 5 is connected, and the exhaust assembly 5 includes a connecting pipe 51. The two ends of the connecting pipe 51 are respectively installed with a flange 52 and a cooling fan 53. After the heat pipe cooling assembly 2 and the exhaust assembly 5 are respectively installed on the inner and outer sides of the distribution box, the evaporation section of the heat pipe cooling assembly 2 can efficiently absorb the heat of the air around the leakage protection switch 6, and maintain efficient operation under the auxiliary heat dissipation of the exhaust assembly 5, compared with the simple air cooling structure, a higher cooling efficiency is achieved, and the normal installation of the leakage protection switch 6 is not affected. The air hole 24 has the same shape and size as the mounting hole opened on the electrical rail 1 and is arranged relative to each other. The air hole 24 arranged relative to the mounting hole opened on the electrical rail 1 It can play a role in making the air flow flow smoothly while avoiding affecting the use of the fixing bolts of the electrical rail 1. The heat pipe 21 and the air hole 24 are staggered left and right. By staggering the heat pipe 21 and the air hole 24, it can avoid that the heat pipe 21 hinders the insertion of the bolts in the air hole 24, thereby affecting the normal installation of the electrical rail 1. The fixing plate 23 is a channel steel structure. The upper and lower flanges of the fixing plate 23 are welded and connected to the inner end surface of the electrical rail 1. The fixing plate 23 can be stably connected to the electrical rail 1. On the one hand, it provides a stable installation support for the heat dissipation fins 22, and on the other hand, it improves the structural strength of the electrical rail 1. The heat dissipation fins 22 are arranged on the upper and lower sides of the air hole 24. side, and the heat dissipation fins 22 are arranged parallel to the upper and lower flanges of the fixing plate 23. After the air enters the cavity formed between the fixing plate 23 and the electrical guide rail 1 through the air holes 24, it can flow smoothly along the surface of the heat dissipation fins 22. The evaporation section of the heat pipe 21 is located on the outside of the electrical guide rail 1, and the condensation section of the heat pipe 21 is located on the inside of the electrical guide rail 1. The use of the heat pipe 21 can effectively improve the heat dissipation efficiency of the exhaust component 5. The connecting pipe 51 is a circular tube structure with openings at both ends. The inner wall of the flange 52 is flush with the inner wall of the air duct of the cooling fan 53. Bolts can be inserted into the bolt holes opened on the flange 52, so that the exhaust component 5 can be installed on the meter box with ease and stability.

[0034] The working principle of this technical solution is as follows: the meter box itself should have a heat dissipation hole structure to ensure the stability of the air pressure in the box when the exhaust assembly 5 is working. A through hole for inserting the air pipe 4 is opened on the meter box, so that the two ends of the air pipe 4 are inserted on the inner and outer sides of the meter box, and bolts are used to insert the flange 52 and the meter box to stably fix the exhaust assembly 5 on the outside of the meter box; the electrical rail 1 is installed in the meter box by the installation method in the prior art, and the leakage protection switch 6 is fixed on the electrical rail 1 to complete the installation of the device; the heat dissipation fan 53 can be externally controlled or directly powered on for continuous operation; after the heat dissipation fan 53 is running, the air in the meter box enters the air gap formed between the electrical rail 1 and the fixing plate 23 through the air hole 24 The air in the inner cavity flows through the surface of the evaporation section of the heat pipe 21 before entering the air hole 24. At this time, the medium in the evaporation section of the heat pipe 21 absorbs heat, vaporizes and rises to the condensation section, thereby achieving the purpose of lowering the air temperature around the leakage protection switch 6. At the same time, the air entering between the electrical guide rail 1 and the fixed plate 23 flows along the surface of the heat dissipation fins 22, and takes away the heat from the surface of the condensation section of the heat pipe 21 by heat transfer, so that the gas medium in the condensation section of the heat pipe 21 is liquefied and refluxed to the evaporation section, realizing cyclic and efficient cooling. The use of the heat pipe structure achieves a higher efficiency cooling than the simple air cooling method.
