[0001] This utility model belongs to the field of substation cable trench technology, and more specifically, it relates to a substation cable trench protection device with automatic dehumidification. Background Technology

[0002] Substation cable trenches are underground passageways within substations used for laying and protecting cables. Cable trenches provide a relatively safe and stable environment for cables, preventing them from being directly exposed to wind, sun, rain, mechanical damage, and damage from small animals. They also facilitate cable laying, inspection, maintenance, and management, allowing maintenance personnel to easily inspect, troubleshoot, and repair cables within the trench. However, traditional cable trenches have poor dehumidification capabilities. This poor dehumidification makes cables and related equipment more prone to failure, requiring maintenance personnel to perform more frequent inspections, maintenance, and repairs. This not only increases labor costs but also affects the normal operation of the substation. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a substation cable trench protection device with automatic dehumidification. This addresses the issue that traditional cable trench dehumidification is weak, which can easily lead to cable and equipment failures, forcing maintenance personnel to conduct frequent inspections and repairs, increasing labor costs and affecting the normal operation of the substation.

[0004] The purpose and effectiveness of this utility model's substation cable trench protection device with automatic dehumidification are achieved through the following specific technical means: A substation cable trench protection device with automatic dehumidification includes a cable trench body and an automatic dehumidification component. The cable trench body has an installation groove. The automatic dehumidification component includes multiple sets of trench covers arranged sequentially in the installation groove. A control box, a humidity sensor, and a dehumidifier are sequentially arranged at the bottom of the multiple sets of trench covers along the arrangement direction. The humidity sensor and the dehumidifier are both electrically connected to the control box. Multiple sets of mounting columns are arranged opposite each other on two opposing inner sides of the cable trench body. Each set of mounting columns has two sets of cable racks for placing cables. An assembly rack is provided inside the cable trench body, and a ventilation fan is provided on the assembly rack for ventilation inside the cable trench body.

[0005] The above technical solution further includes that multiple sets of trench cover plates are provided with hook holes for separating the trench cover plate from the cable trench body; multiple sets of anti-slip textures are also uniformly provided on the trench cover plate.

[0006] The above technical solution further includes that the trench cover plate on which the dehumidifier is installed has a through-hole for ventilation, and a filter screen is detachably installed on the vent at the top of the trench cover plate.

[0007] The above technical solution further includes that a mounting block is provided on one side of the cable rack, and a sliding groove is provided on the mounting column corresponding to the mounting block, and the cable rack is movably inserted into the sliding groove through the mounting block.

[0008] The above technical solution further includes that the mounting column is uniformly provided with multiple sets of assembly holes, the mounting block is provided with positioning holes corresponding to the assembly holes, and the positioning holes and the assembly holes are provided with the same set of limiting bolts.

[0009] The above technical solution further includes that the cable rack is provided with a dividing protrusion, and two sets of locking holes are provided through the cable rack on both sides of the dividing protrusion, and the same set of U-shaped locking rods for fixing the cable are provided in the two sets of locking holes.

[0010] The above technical solution further includes that a drainage ditch is provided inside the main body of the cable trench, and multiple sets of condensation tanks with condensation plates are provided inside the main body of the cable trench on both sides of the drainage ditch.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. A humidity sensor monitors the humidity in the cable trench in real time, and the data is transmitted to the control box. When the humidity exceeds the set value, the control box activates the dehumidifier and ventilation fan, combined with the condenser fins in the condensation tank to assist in dehumidification and reduce the humidity in the trench. A drainage ditch can drain accumulated water, reducing repeated increases in humidity. The cable rack's height is adjustable via mounting blocks that engage with mounting column grooves, and it is secured with limit bolts. U-shaped locking rods pass through lock holes to secure cables, preventing cable slippage and wear. These structures work together to reduce malfunctions caused by moisture and cable damage, lowering the frequency of equipment maintenance.

[0012] 2. The trench cover features hook holes for easy separation, and its anti-slip texture enhances safety. The vent filter is removable for convenient cleaning and maintenance. The cable rack mounting block mates with the sliding track, and the assembly holes and positioning holes are secured by limit bolts, allowing for easy adjustment of position according to the number of cables. The control box is linked to the humidity sensor and dehumidifier to achieve automatic dehumidification, reducing the frequency of manual inspections.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0021] like Figures 1 to 6 As shown, this utility model provides a substation cable trench protection device with automatic dehumidification, including a cable trench body 1 and an automatic dehumidification component. The cable trench body 1 is provided with an installation groove. The automatic dehumidification component includes multiple sets of trench cover plates 2 arranged sequentially in the installation groove. The bottom of the multiple sets of trench cover plates 2 is provided with a control box 3, a humidity sensor 101 and a dehumidifier 102 in sequence along the arrangement direction. The humidity sensor 101 and the dehumidifier 102 are both electrically connected to the control box 3. Multiple sets of mounting columns are provided on two opposite inner sides of the cable trench body 1. Each set of mounting columns is provided with two sets of cable racks 103 for placing cables. An assembly rack 104 is provided inside the cable trench body 1. A ventilation fan 105 for ventilation inside the cable trench body 1 is provided on the assembly rack 104. The cable trench body 1 is provided with an installation groove, which provides an installation base for multiple sets of trench covers 2, so that the trench covers 2 can be stably arranged to cover and form a closed space, reducing the impact of the external environment on the interior. At the same time, the structure of the installation groove facilitates the positioning and disassembly of the trench covers 2. The trench covers 2 are arranged in sequence in the installation groove, which can completely cover the cable trench body 1, blocking rainwater, dust and other debris from entering. The multiple arrangement structure also makes it easy to disassemble a single trench cover 2, which is convenient for local maintenance without the need for complete removal, thus improving operational efficiency.

[0022] The control box 3 is electrically connected to the humidity sensor 101 and the dehumidifier 102 to form a linkage system. The data monitored by the humidity sensor 101 can be transmitted to the control box 3. The control box 3 automatically controls the operation of the dehumidifier 102 according to the preset threshold, realizing dehumidification adjustment without manual operation and ensuring stable humidity in the trench. The dehumidifier 102 can be an ARS-E60 model dehumidifier.

[0023] Humidity sensor 101 is located at the bottom of the trench cover 2, allowing direct contact with the air inside the cable trench body 1 to capture humidity changes. This provides data support for the control box 3, ensuring the dehumidifier 102 starts and stops at appropriate times, preventing insufficient or excessive dehumidification. The dehumidifier 102, installed at the bottom of the trench cover 2, directly dehumidifies the air inside the cable trench body 1. Its proximity to the trench space allows for rapid action on damp areas, improving dehumidification efficiency and reducing the impact of accumulated humidity on the cables. Multiple sets of mounting posts on the two opposite inner sides of the cable trench body 1 provide fixed support points for the cable rack 103, ensuring stable installation. The distribution of these posts can accommodate different numbers of cables, enhancing structural flexibility. The humidity sensor 101 can be an MD-HT101 model; the control box 3 can be an SPT2-404020 model, and the device connects to external power supply equipment via cables.

[0024] The two sets of cable racks 103 on each set of mounting columns allow for layered placement of cables, preventing different cables from tangling and squeezing each other, reducing friction damage. At the same time, the layered structure facilitates individual maintenance of a specific layer of cables, improving maintenance convenience. The mounting frame 104 provides a mounting carrier for the ventilation fan 105, allowing it to be stably installed inside the cable trench body 1, ensuring the stability of the ventilation fan 105 during operation and preventing positional displacement due to vibration from affecting the ventilation effect. The ventilation fan 105 on the mounting frame 104 can accelerate the airflow inside the cable trench body 1, delivering the dry air processed by the dehumidifier 102 to each area, while simultaneously exhausting humid air, forming an air circulation, enhancing the overall dehumidification effect, and preventing excessively high local humidity.

[0025] like Figure 1 As shown, multiple sets of trench cover plates 2 are provided with hook holes 201 for separating the trench cover plate 2 from the cable trench body 1; multiple sets of anti-slip textures 202 are also evenly provided on the trench cover plate 2; a ventilation opening for ventilation is provided through the trench cover plate 2 with a dehumidifier 102 installed, and a filter screen 301 is detachably installed on the ventilation opening at the top of the trench cover plate 2. The multiple sets of trench cover plates 2 are provided with hook holes 201, and external force can be applied by hooking the hook holes 201 with tools to separate the trench cover plate 2 from the cable trench body 1, reducing the difficulty of disassembly, saving manpower, and facilitating quick opening of the trench cover plate 2 for internal operations; the multiple sets of anti-slip textures 202 on the trench cover plate 2 can increase the friction of the contact surface, reduce the risk of slipping when personnel step on it, and improve operational safety.

[0026] The trench cover 2, equipped with a dehumidifier 102, has ventilation openings that serve as air circulation channels. When the dehumidifier 102 is running, dry external air enters through the ventilation openings, while humid internal air is discharged through them, ensuring the dehumidifier 102 functions properly. A removable filter 301 is installed on the ventilation opening at the top of the trench cover 2 to prevent external dust and debris from entering the cable trench body 1, thus avoiding their adhesion to internal equipment and affecting operation. The removability also facilitates regular cleaning or replacement of the filter 301, keeping the ventilation opening unobstructed. The hook holes 201, anti-slip textures 202, ventilation openings, and filter 301 are all located on the trench cover 2, forming an integral structure with the trench cover 2. This eliminates the need to occupy additional internal space in the cable trench body 1, does not affect the internal equipment layout, and allows for simultaneous installation and removal of the trench cover 2.

[0027] like Figure 3 , Figure 5 and Figure 6 As shown, a mounting block 401 is provided on one side of the cable rack 103, and a groove is provided on the mounting post corresponding to the mounting block 401. The cable rack 103 is movably inserted into the groove through the mounting block 401. Multiple sets of assembly holes 501 are evenly provided on the mounting post, and positioning holes 502 are provided on the mounting block 401 corresponding to the assembly holes 501. The same set of limit bolts are inserted into the positioning holes 502 and the assembly holes 501. The cable rack 103 is inserted into the groove of the mounting post through the mounting block 401, so that the cable rack 103 can slide along the groove, which is convenient for adjusting the position according to the number and specifications of cables, adapting to different wiring needs, and improving installation flexibility. The cooperation between the mounting block 401 and the groove provides stable support for the cable rack 103, preventing the cable rack 103 from tilting or falling off, ensuring that the cables are placed stably, and reducing cable damage caused by unstable support.

[0028] The mounting column has multiple sets of assembly holes 501, and the mounting block 401 corresponds to the positioning hole 502. A limit bolt passes through both, fixing the position of the cable rack 103 and preventing accidental movement within the groove, ensuring a stable cable layout. The multiple sets of assembly holes 501 allow for adjustment of the connection position between the mounting block 401 and the mounting column, thereby changing the height of the cable rack 103 to accommodate cables of different diameters, enhancing the device's versatility and reducing adaptation costs. The combined structure of the mounting block 401, groove, assembly holes 501, positioning holes 502, and limit bolt facilitates the disassembly and replacement of the cable rack 103. When the cable rack 103 is damaged or requires adjustment, quick operation is possible, improving maintenance efficiency.

[0029] The cable rack 103 is equipped with a dividing protrusion 601. Two sets of locking holes are provided on both sides of the cable rack 103, and the same set of U-shaped locking rods 602 for fixing cables are installed in the two sets of locking holes. The dividing protrusion 601 can divide the surface of the cable rack 103 into multiple independent areas, allowing different cables to be placed in different areas, avoiding cable tangling, facilitating the differentiation of cables with different functions, improving wiring clarity, and reducing identification time. The two sets of locking holes on both sides of the dividing protrusion 601 allow the U-shaped locking rods 602 to pass through the locking holes, which can fix the cables placed in the divided areas, preventing the cables from shifting or falling due to air flow in the trench or external vibration, ensuring the stability of the cable position, and reducing wear caused by movement. The mating structure of the U-shaped locking rods 602 and the locking holes facilitates quick installation and disassembly. When it is necessary to add, remove, or replace cables, it can be easily operated, improving maintenance efficiency. At the same time, it can adapt to the fixing needs of different numbers of cables, enhancing the flexibility of use.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, the cable trench body 1 is also equipped with a drainage ditch 701, and multiple sets of condensation tanks 702 with condensing fins are installed on both sides of the drainage ditch 701. The drainage ditch 701 in the cable trench body 1 can collect water accumulated in the trench and drain it through its own slope or auxiliary equipment, avoiding long-term water retention that would cause the humidity in the trench to rise, reducing the soaking of cables and equipment by water, and reducing the risk of corrosion. The multiple sets of condensation tanks 702 with condensing fins on both sides of the drainage ditch 701 can condense water vapor in the air into water droplets, which drip into the drainage ditch 701 and are discharged, enhancing the dehumidification effect. In combination with other dehumidification components, it forms a multi-stage dehumidification mechanism to improve the dryness of the trench. The multiple sets of condensation tanks 702 distributed on both sides of the drainage ditch 701 can cover more areas, so that water vapor in different locations in the trench can be treated, avoiding excessive local humidity. At the same time, the condensate is directly discharged into the drainage ditch 701, forming a closed loop of water vapor treatment and improving dehumidification efficiency.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
