[0024] Figure 2 is an exploded schematic diagram of the present invention;

[0025] Figure 3 It is a cross-sectional schematic diagram of the present invention. DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 3 As shown, the present invention relates to a turnout control box drying device, which is mainly used to improve the drying effect inside the turnout control box, thereby ensuring the stability and reliability of the control system. The drying device has a reasonable structural design and comprehensive functions, and effectively solves the problem that traditional turnout control boxes are prone to water accumulation in humid environments.

[0028] The device comprises a box body 1 located inside a turnout control box, and an opening 11 is provided on the upper part of the box body 1. A top cover 2 is detachably connected to the opening 11. The top cover 2 is composed of a cover frame 21 and a water-absorbing film 22. The water-absorbing film 22 is made of a water-absorbing material, such as a polyvinyl alcohol (PVA) film. The water-absorbing film has good water absorption capacity, can continuously absorb water inside the turnout control box, and keep the internal environment dry.

[0029] A desiccant 3 is provided inside the box body 1, which can effectively enhance the dehumidification capacity and ensure that moisture will not affect important electrical components and oil pumps. A water outlet 12 is provided at the bottom of the box body 1, and the water outlet is connected to the oil leakage hole on the control box through a drain pipe 4, so that excess moisture inside the control box can be smoothly discharged to the outside of the control box, avoiding the retention of moisture in the control box.

[0030] Specifically, when the water absorption film 22 absorbs the water in the switch control box, if the water reaches a certain saturation level, the water absorption film 22 will drop the excess water onto the desiccant 3. The desiccant 3 further improves the drying effect of the internal environment by absorbing the water. This design realizes the multi-level management of water: first, it is collected by the water absorption film, and then deeply adsorbed by the desiccant.

[0031] In order to increase the practicality and convenience of the desiccant 3, the design takes into account the replaceability of the desiccant. The desiccant 3 can be made of highly efficient water-absorbing particles such as calcium chloride and silica gel, and the user can replace it regularly as needed. More preferably, the desiccant 3 can also be made of a vanishing desiccant such as soda lime. When the soda lime absorbs water, it will be converted into a mud flow state with strong fluidity, and can be smoothly discharged to the outside of the control box through the drain pipe 4. This design not only reduces the frequency of maintenance, but also avoids the re-evaporation of the water absorbed in the desiccant, thereby improving the overall drying effect of the turnout control box.

[0032] Furthermore, a layer of support net 5 is detachably installed in the inner cavity of the box body 1, and the support net 5 is designed to effectively support the desiccant 3 so that it is suspended inside the box body. This suspended design not only increases the contact area of ​​the desiccant and improves its ability to adsorb moisture, but also facilitates the subsequent drainage process. Through the function of the support net, the desiccant 3 no longer directly contacts the bottom of the box body, avoiding water accumulation caused by a humid environment and ensuring the efficiency of the use of the desiccant.

[0033] Preferably, the inner cavity of the box body 1 is also filled with a layer of buffer cotton, especially around the desiccant 3. The setting of such buffer cotton can effectively reduce the shaking of desiccant particles caused by equipment vibration, ensure the stability and uniformity of the desiccant during use, and thus improve the overall dehumidification effect.

[0034] Furthermore, a funnel-shaped water collection chamber 13 is provided at the bottom of the inner cavity of the box body 1. The design of the water collection chamber 13 allows the water flow to naturally gather at the lowest point, which is convenient for subsequent drainage. The drain port 12 is located at the lowest position of the water collection chamber 13, ensuring that when water accumulates, the water can be quickly and smoothly discharged to keep the inside of the control box dry.

[0035] In order to avoid interference with the fixing device mentioned later, the lower part of the water collecting chamber 13 is deliberately designed to be biased to one side. This design takes into account the spatial relationship between the water collecting chamber and the fixing device, ensuring that during use, the shape and position of the water collecting chamber will not affect the normal function of the fixing device. By offsetting the lower part of the water collecting chamber 13, sufficient space can be effectively freed up to provide the necessary range of movement and installation position for the fixing device.

[0036] In order to enhance the function of the drainage system, a U-shaped or V-shaped trap pipe section 41 is provided on the drainage pipe 4. The design of the trap pipe section 41 is similar to the trap pipe in the toilet sewer pipe, and its main function is to prevent small animals such as insects, rats, and ants from entering the drainage pipe. At the same time, the trap pipe section 41 can also effectively block the communication between the internal and external gases, further protecting the stability of the internal environment of the turnout control box.

[0037] In addition, the drain pipe 4 is detachably connected with a joint 42, which is used to connect the drain pipes 4 at two ports together. Both ends of the joint 42 are threaded, which is convenient for disassembly and maintenance. A pocket-shaped filter 421 can also be connected to the joint 42 as a secondary protection to further prevent small animals such as insects, rats, and ants from entering the drainage system. Of course, it is also possible to choose not to set the water trap pipe section 41, and use the filter 421 alone to achieve the protection function.

[0038] Furthermore, a one-way valve 7 is provided on the drainage pipe 4, which can not only prevent the entry of small animals such as insects, rats, ants, etc., but also prevent the backflow of water, ensure the unidirectionality of the drainage system, and effectively maintain the dry environment inside the switch control box.

[0039] Finally, a connection seat 8 is provided at the lower end of the drain pipe 4, and a hollow drain bolt 81 is rotatably connected to the connection seat 8. The inner cavity of the drain bolt 81 is connected to the drain pipe 4 and is fixed in the oil leakage hole of the turnout control box through a threaded connection. This design facilitates the fixing of the drain pipe 4 and ensures that the water flow can be smoothly discharged to the outside, effectively enhancing the stability and reliability of the overall drainage system.

[0040] Furthermore, in order to prevent the drying device from shaking or loosening during operation, thereby affecting the normal operation of other components in the turnout control box, a special fixing device 6 is provided on the box body 1. This fixing device 6 can effectively fix the box body 1 firmly in the turnout control box, ensuring the stability and reliability of the entire system when in use.

[0041] Preferably, the fixing device 6 is composed of a hoop 61 connected to the bottom of the box body 1 and a locking bolt 62 for locking the hoop 61. The design of the hoop 61 enables it to be firmly clamped in the oil pump position in the control box. Such a configuration not only enhances the fixing strength, but also adapts to the structure inside the control box and provides a better support effect. By adjusting the locking bolt 62, the tightness of the hoop 61 can be adjusted at any time as needed, thereby realizing a flexible fixing solution.

[0042] Furthermore, the cover frame 21 of the top cover 2 is tightly combined at the opening 11 by means of a snap connection. At the same time, in order to further enhance the firmness between the top cover 2 and the box body 1, a strapping belt 9 (such as Figure 1 As shown, the two ends of the strapping belt 9 are connected to the box body, and the middle is pressed on the top cover 2). The strapping belt 9 not only reinforces the top cover 2, but also effectively prevents the top cover from shaking or detaching due to vibration during use.

[0043] Through this multiple fixing method, the entire drying device can maintain good stability inside the turnout control box, ensuring the effective operation of each component whether in normal working conditions or in a high vibration environment. This design improves the overall performance and service life of the equipment, providing users with a safer and more reliable operating experience.
