Description

Technical Field

[0001] This utility model relates to the field of main unit chassis technology, and in particular to a main unit chassis for controlling building sewage equipment. Background Technology

[0002] In modern building sewage systems, the control unit serves as the core hub, undertaking key functions such as equipment operation monitoring, command execution, and fault early warning. However, traditional control units expose many shortcomings in complex building environments: insufficient heat dissipation efficiency leads to overheating and aging of components during long-term high-load operation, shortening equipment lifespan; inadequate dustproof performance causes dust accumulation, posing a risk of short circuits; vibration and electromagnetic interference often cause unstable control signals, affecting the accurate operation of sewage equipment.

[0003] With the upgrading of building intelligence, the requirements for the reliability, compatibility, and environmental adaptability of sewage systems have significantly increased. Existing equipment is difficult to adapt to the coordinated control of multiple brands of sewage pumps, valves, and other terminals, and lacks remote monitoring and intelligent protection mechanisms, increasing manual maintenance costs. Therefore, technical optimization for heat dissipation, dust prevention, anti-interference, and intelligent management has become an urgent need to improve the stability and energy efficiency of building sewage systems.

[0004] CN107861573A discloses a control unit for building sewage equipment, including a base. The top of the base is fixedly connected to the main unit body via a fixing rod. From left to right, a blower and a water tank are fixedly connected to the top of the base. An air supply pipe is fixedly connected to the air outlet of the blower. The end of the air supply pipe away from the blower passes through and extends into the inner cavity of the water tank. The air outlet at the top of the water tank is fixedly connected to the air inlet at the bottom of the main unit body via an air outlet pipe. This control unit for building sewage equipment, through the cooperation of the blower, water tank, air supply pipe, and air outlet pipe, can ensure that the internal parts of the main unit body do not accumulate a large amount of dust, thereby improving the heat dissipation rate of the internal parts of the main unit body, ensuring that the temperature of the internal parts of the main unit body does not become too high, and extending the service life of the internal parts of the main unit body. However, it does not solve the problems of convenient heat dissipation and moisture prevention. Therefore, we propose a control unit for building sewage equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies in terms of heat dissipation and moisture prevention, and to propose a control unit for building sewage equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A control unit for building sewage equipment includes a support base and a protective assembly. The protective assembly is fixedly connected to the top of the support base. The protective assembly includes an outer protective shell. Two sets of connecting rods are fixedly connected to the left and right sides of the inner wall of the outer protective shell. A U-shaped protective plate is fixedly connected to the ends of the two sets of connecting rods away from the outer protective shell. Multiple hanging brackets are fixedly connected to the left and right sides of the inner wall of the U-shaped protective plate by fixing bolts. A support net is fixedly connected to the upper end of each of the multiple hanging brackets. An air inlet is opened in the middle of the lower surface of the outer protective shell, and an air outlet is opened on the upper surface of the outer protective shell. Two filter mounting brackets are fixedly connected inside the air inlet and the air outlet. Filter screens are fixedly connected inside the filter mounting brackets. Two exhaust fans are fixedly connected to the lower end of the upper filter mounting bracket and the upper end of the lower filter mounting bracket.

[0007] As a further improvement of this utility model: the air inlet and the air outlet are relatively vertically symmetrical, and the air inlet is larger than the air outlet, and the edges of the U-shaped protective plate are all wavy.

[0008] The symmetrical layout of the air inlet and outlet, with the inlet larger than the outlet, creates a chimney-like ventilation structure. This layout allows hot air to be expelled more smoothly from the outlet by the exhaust fan, while cool air is quickly replenished from the inlet, enhancing air convection efficiency and effectively reducing the internal temperature of the chassis. The wavy design of the U-shaped protective plate cuts and turbulents the airflow as it passes through. This ensures a more even distribution of airflow inside and around the U-shaped protective plate, achieving more efficient and uniform cooling of the chassis and preventing damage to the equipment from localized overheating.

[0009] This design further optimizes the ventilation and heat dissipation system, which not only improves heat dissipation efficiency but also makes the internal temperature distribution more uniform, helping to extend the service life of the equipment inside the chassis and ensuring that the equipment operates in a stable temperature environment.

[0010] As a further improvement of this utility model: both the U-shaped protective plate and the outer protective shell have two sets of square holes on the left and right sides, and two louvers are fixedly connected inside the square holes on the left and right sides of the outer protective shell.

[0011] The square holes on the left and right sides of the U-shaped protective plate and outer protective shell provide installation positions for the louvers. The louvers are fixed inside the square holes, and their adjustable blade angles allow for control of ventilation volume and direction. When it is necessary to adjust the ventilation inside the main unit chassis, the louver blade angle can be adjusted. This adjustment method allows for flexible control of ventilation volume and direction based on the actual environment and the internal temperature requirements of the main unit chassis, further optimizing airflow within the chassis, enhancing heat dissipation, or preventing adverse external airflow from affecting the internal environment of the chassis.

[0012] The louvers not only increase the flexibility of ventilation adjustment, but also block external debris from entering the main unit, thus providing protection and improving the stability and safety of the equipment inside the main unit.

[0013] As a further embodiment of this utility model: a door frame is fixedly connected to the surface of the outer protective shell, a protective door is movably connected to the surface of the door frame, and a controller is fixedly connected to the lower surface of the inner wall of the outer protective shell on one side of the air inlet.

[0014] The fixed connection between the outer protective shell and the door frame provides the mounting base for the protective door. The protective door, through its movable connection with the door frame, protects the internal equipment of the main unit chassis while facilitating operation and maintenance by personnel. The protective door can be opened when installation, debugging, or repair of the internal equipment is required; otherwise, it is closed to prevent external factors from damaging the internal equipment. This opening and closing mechanism achieves the goal of protecting the internal equipment of the main unit chassis while facilitating personnel operation and maintenance.

[0015] The controller, fixedly connected to the lower inner surface of the outer protective casing on one side of the air inlet, can acquire environmental parameters such as air temperature and humidity near the air inlet at close range. This positioning allows the controller to more accurately sense changes in the internal environment of the main unit, thereby more precisely controlling the operation of the exhaust fans and louvers at the air inlet and outlet. This achieves the goal of timely and accurate adjustment of the internal environment based on the actual conditions inside the main unit, ensuring stable equipment operation.

[0016] This design takes into account both the protection and ease of operation of the equipment, as well as the precise control of the internal environment, thereby improving the overall performance and practicality of the main unit.

[0017] As a further improvement of this utility model: multiple guide flow pipes are provided inside the support base, and a ventilation opening is provided in the middle of the lower surface of the support base, with a trapezoidal guide shell fixedly connected around the lower end of the ventilation opening.

[0018] Multiple guide pipes are installed inside the support base, interconnected to form a drainage channel. When water enters the support base, it flows along these guide pipes. This design quickly guides water into the ventilation openings, preventing water accumulation inside the support base and thus protecting it from damage to the support base and the internal equipment of the main unit.

[0019] A vent in the center of the lower surface of the support base provides an outlet for water discharged from the guide pipe, while also facilitating air circulation within the support base and preventing equipment corrosion caused by a humid environment. A trapezoidal guide shell, fixedly connected to the lower end of the vent, disperses and guides the water discharged from the vent. This structure prevents the discharged water from concentrating and impacting a single area, avoiding damage to the surrounding environment, and further prevents water from flowing back into the support base or main unit chassis, thus protecting the main unit chassis and its surrounding environment.

[0020] The coordinated design of the flow guide pipe, ventilation port, and trapezoidal guide shell ensures the safe and stable operation of the main unit chassis from multiple aspects such as drainage, ventilation, and waterproof backflow, and improves the adaptability and reliability of the main unit chassis in humid environments.

[0021] As a further embodiment of this utility model: a support assembly is fixedly connected to the lower end of the support base, the support assembly includes four threaded sleeves, the four threaded sleeves are installed at the four corners of the lower surface of the support base, and four threaded rods are rotatably connected inside the four threaded sleeves through threads.

[0022] The lower end of the support base is fixedly connected to the support assembly, providing a support structure for the entire main unit chassis. Four threaded sleeves are installed at the four corners of the lower surface of the support base, providing installation positions for the threaded rod. The threaded rod is rotatably connected to the threaded sleeve via threads. When the height of the main unit chassis needs to be adjusted, the threaded rod is rotated, and through the transmission principle of the threads, the threaded rod moves up and down within the threaded sleeve. This adjustment method allows for flexible adjustment of the main unit chassis height according to the flatness of different working surfaces, ensuring the main unit chassis is placed stably and improving its adaptability to different working environments.

[0023] The design of this support component uses a threaded connection, which makes height adjustment simple and convenient. At the same time, the threaded connection has a certain degree of self-locking, which can maintain a stable support state after the main unit is adjusted to a suitable height, ensuring the safe and stable operation of the main unit.

[0024] As a further embodiment of this utility model: four support legs are fixedly connected to the lower ends of the four threaded rods, and four fixing nuts are fixedly connected to the surface of the threaded rods located at the upper ends of the support legs by welding.

[0025] The fixed connection between the lower end of the threaded rod and the support leg makes the support leg the support point where the main unit chassis contacts the ground. The four support legs are evenly distributed at the bottom of the main unit chassis. By contacting the ground, the weight of the main unit chassis is evenly distributed to the ground, so as to provide stable support for the main unit chassis and prevent the main unit chassis from tipping over.

[0026] A fixing nut welded to the threaded rod at the upper end of the support leg provides an operating point for adjusting the support leg height. By turning the fixing nut with an external wrench, the threaded rod can be easily rotated within the threaded sleeve, thereby adjusting the support leg height. The welding method ensures a secure connection between the fixing nut and the threaded rod, preventing the fixing nut from loosening during frequent adjustments of the support leg height, thus guaranteeing the reliability and stability of the height adjustment operation.

[0027] The design of the support legs and fixing nuts is closely matched, which not only ensures the stable support of the main unit, but also makes the height adjustment operation convenient and reliable, meeting the requirements of the main unit for stability and adaptability in different working scenarios.

[0028] Compared with the prior art, the present invention provides a main control box for building sewage discharge equipment, which has the following advantages: 1. In this invention, the air inlet and exhaust outlet are vertically symmetrical, with the air inlet being larger than the exhaust outlet. This layout forms a chimney-like ventilation structure. When the internal temperature of the main unit rises, the hot air naturally rises and is exhausted through the exhaust outlet. Due to the larger area of ​​the air inlet, cool air can be replenished more quickly. Combined with the operation of the exhaust fans inside the air inlet and exhaust outlet, the air convection effect is enhanced, achieving the goal of efficiently exhausting hot air from inside the main unit and reducing the internal temperature.

[0029] The U-shaped protective plate has a wavy edge design. When cold air enters from the air inlet and passes through the U-shaped protective plate, the wavy edge cuts and disrupts the airflow. This makes the airflow more evenly distributed inside and around the U-shaped protective plate. Through this even airflow distribution, the internal temperature of the main unit is cooled more comprehensively and evenly, avoiding damage to the equipment due to excessively high local temperatures.

[0030] Both the U-shaped protective plate and the outer protective shell have two sets of square holes on both sides, with louvers fixed inside. The airflow volume and direction can be flexibly controlled by adjusting the angle of the louver blades. When environmental parameters such as temperature and humidity inside the main unit need adjustment, the louver blade angle can be changed accordingly. This adjustment method allows for precise control of ventilation based on the actual environmental needs inside the main unit, further optimizing internal airflow, enhancing heat dissipation, and preventing undesirable airflow, dust, or debris from entering the main unit, thus protecting the internal equipment.

[0031] A door frame is fixedly connected to the surface of the outer protective shell, and the door frame is movably connected to the protective door. When the protective door is closed, it effectively blocks external dust, debris, and accidental collisions from damaging the internal equipment, providing a safe operating environment for the internal equipment. When it is necessary to install, debug, or repair the internal equipment, the protective door can be opened. This opening and closing method achieves the purpose of both protecting the internal equipment and facilitating operation and maintenance by the operators.

[0032] In summary, the protective components achieve efficient heat dissipation for the main unit through a unique layout of the air inlet and outlet, a U-shaped protective plate with wavy edges, louvered ventilation adjustment, and a protective door designed for both equipment protection and ease of operation. Simultaneously, the internal support base includes a guide pipe, ventilation openings, and a trapezoidal guide shell, effectively guiding water flow and preventing internal moisture absorption. These functions work together to provide the device with excellent heat dissipation and moisture resistance, ensuring stable operation of the internal equipment and meeting the requirements of a main unit control box for building sewage treatment equipment in practical operating environments.

[0033] 2. This utility model includes a support assembly fixedly connected to the lower end of a support base. The support assembly comprises four threaded sleeves located at the four corners of the lower surface of the support base. The threaded sleeves provide space for the installation and movement of threaded rods, and the four threaded rods are rotatably connected to their corresponding threaded sleeves via threads. When the height of the main unit needs to be adjusted, the user uses a tool (such as an external wrench) to rotate the fixing nut located on the surface of the threaded rod and welded to the upper end of the support leg. Because the fixing nut is tightly connected to the threaded rod, rotating the fixing nut will cause the threaded rod to rotate inside the threaded sleeve. According to the transmission principle of the thread, the rotation of the threaded rod is converted into its up-and-down movement along the axial direction of the threaded sleeve. In this way, precise adjustment of the support leg height is achieved, enabling the main unit to adapt to working surfaces with different flatness levels, meeting the needs of use in various complex terrain conditions.

[0034] The lower ends of the four threaded rods are fixedly connected to four support legs, which are evenly distributed at the bottom of the chassis and in direct contact with the ground. When the chassis is placed on the ground, the support legs bear the entire weight of the chassis and distribute it evenly across the ground. This uniform weight distribution provides a stable support foundation for the entire chassis, ensuring that the chassis will not tilt or tip over due to uneven ground or uneven stress during use, thus improving the stability of the chassis.

[0035] Four fixing nuts, welded together on the threaded rod surface at the upper end of the support leg, not only provide a point of leverage for adjusting the support leg height, but also ensure a secure connection between the fixing nuts and the threaded rod. During frequent height adjustments, this robust connection effectively prevents the fixing nuts from loosening, ensuring the reliability of the height adjustment operation. This structural design ensures the stability of the support assembly during long-term use, maintaining a stable support state for the main unit chassis and further improving the reliability of the main unit chassis under different operating environments.

[0036] In summary, the support assembly achieves free height adjustment through the cooperation of the threaded sleeve and the threaded rod, improves support stability by evenly distributing weight using the support legs, and ensures structural stability through the firm welding of the fixing nut and the threaded rod. Thus, the device can freely adjust its height and support stability, significantly improving the stability of the entire device in different working scenarios and meeting the requirements for stable placement of the main control box for building sewage discharge equipment.

[0037] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0042] Example: Reference Figures 1 to 5 A control unit for building sewage discharge equipment includes a support base 1 and a protective assembly 2. The protective assembly 2 is fixedly connected to the top of the support base 1. The protective assembly 2 includes an outer protective shell 201. Two sets of connecting rods 202 are fixedly connected to the left and right sides of the inner wall of the outer protective shell 201, respectively. A U-shaped protective plate 203 is fixedly connected to the end of the two sets of connecting rods 202 away from the outer protective shell 201. Multiple hanging brackets 205 are fixedly connected to the left and right sides of the inner wall of the U-shaped protective plate 203 by fixing bolt groups 204. Each of the hanging brackets 205 has a support net 206 fixedly connected to its upper end. An air inlet 207 is provided in the middle of the lower surface of the outer protective shell 201, and an air outlet 208 is provided on the upper surface of the outer protective shell 201. Two filter mounting brackets 209 are fixedly connected inside the air inlet 207 and the air outlet 208. A filter screen 210 is fixedly connected inside the filter mounting bracket 209. Two exhaust fans 211 are fixedly connected to the lower end of the upper filter mounting bracket 209 and the upper end of the lower filter mounting bracket 209. The air inlet 207 and the air outlet 208 are relatively vertically symmetrical, and the air inlet 207 is larger than the air outlet 208. The edges of the U-shaped protective plate 203 are all wavy. Both the U-shaped protective plate 203 and the outer protective shell 201 have two sets of square holes 218 on the left and right sides. Two louvers 212 are fixedly connected inside the square holes 218 on the left and right sides of the outer protective shell 201. A door frame 213 is fixedly connected to the surface of the outer protective shell 201, and a protective door 214 is movably connected to the surface of the door frame 213. A controller 3 is fixedly connected to the lower surface of the inner wall of the outer protective shell 201 on one side of the air inlet 207. Multiple guide tubes 215 are provided inside the support base 1, and a vent 216 is provided in the middle of the lower surface of the support base 1. A trapezoidal guide shell 217 is fixedly connected around the lower end of the vent 216. In this embodiment, the air inlet 207 and the exhaust vent 208 are vertically symmetrical, with the air inlet 207 being larger than the exhaust vent 208. This layout forms a chimney-like ventilation structure. When the internal temperature of the main unit chassis rises, the hot air naturally rises and is exhausted through the exhaust vent 208. Due to the larger area of ​​the air inlet 207, cool air can be replenished more quickly. Combined with the operation of the exhaust fan 211 inside the air inlet 207 and the exhaust vent 208, the air convection effect is enhanced, achieving the goal of efficiently exhausting hot air from inside the main unit chassis and reducing the internal temperature. The edge of the U-shaped protective plate 203 is designed with a wavy shape. When cold air enters from the air inlet 207 and passes through the U-shaped protective plate 203, the wavy edge cuts and disturbs the airflow. This makes the airflow more evenly distributed inside and around the U-shaped protective plate 203. Through this uniform airflow distribution, more comprehensive and even cooling of the inside of the main unit is achieved, avoiding damage to the equipment due to excessively high local temperatures. Both the U-shaped protective plate 203 and the outer protective shell 201 have two sets of square holes 218 on their left and right sides, with louvers 212 fixed inside the square holes 218. By adjusting the angle of the louvers 212, flexible control of ventilation volume and direction can be achieved. When environmental parameters such as temperature and humidity inside the main unit chassis need adjustment, the angle of the louvers 212 can be changed according to the actual situation. This adjustment method achieves precise control of ventilation based on the actual environmental needs inside the main unit chassis, further optimizing internal airflow, enhancing heat dissipation, and preventing external airflow, dust, or debris from entering the main unit chassis, thus protecting the internal equipment. A door frame 213 is fixedly connected to the surface of the outer protective shell 201, and the door frame 213 is movably connected to the protective door 214. When the protective door 214 is closed, it can effectively block external dust, debris, and accidental collisions from damaging the internal equipment of the main unit chassis, providing a safe operating environment for the internal equipment. When it is necessary to install, debug, or maintain the internal equipment of the main unit chassis, the protective door 214 can be opened. This opening and closing method achieves the purpose of both protecting the safety of the internal equipment and facilitating the operation and maintenance of the equipment by the operators. refer to Figure 1 The lower end of the support base 1 is fixedly connected to a support component 4. The support component 4 includes four threaded sleeves 401. The four threaded sleeves 401 are installed at the four corners of the lower surface of the support base 1. The four threaded sleeves 401 are all connected to four threaded rods 402 through threads. The lower ends of the four threaded rods 402 are fixedly connected to four support legs 403, and the surface of the threaded rods 402 located on the upper end of the support legs 403 is fixedly connected to four fixing nuts 404 by welding. In this embodiment, a support assembly 4 is fixedly connected to the lower end of the support base 1. The support assembly 4 includes four threaded sleeves 401 located at the four corners of the lower surface of the support base 1. The threaded sleeves 401 provide space for the installation and movement of the threaded rods 402. The four threaded rods 402 are rotatably connected to their corresponding threaded sleeves 401 via threads. When the height of the main unit needs to be adjusted, the user uses a tool (such as an external wrench) to rotate the fixing nut 404 located on the surface of the threaded rod 402 and welded to the upper end of the support leg 403. Since the fixing nut 404 is tightly connected to the threaded rod 402, rotating the fixing nut 404 will cause the threaded rod 402 to rotate inside the threaded sleeve 401. According to the transmission principle of the thread, the rotation of the threaded rod 402 is converted into its up-and-down movement along the axial direction of the threaded sleeve 401. In this way, the height of the support leg 403 can be precisely adjusted, enabling the main unit to adapt to working surfaces with different flatness and meeting the needs of use in various complex terrain conditions. The lower ends of the four threaded rods 402 are fixedly connected to four support legs 403, which are evenly distributed at the bottom of the main unit chassis and in direct contact with the ground. When the main unit chassis is placed on the ground, the support legs 403 bear the entire weight of the main unit chassis and distribute it evenly on the ground. This uniform weight distribution provides a stable support foundation for the entire main unit chassis, ensuring that the main unit chassis will not tilt or tip over due to uneven ground or uneven force during use, thereby improving the stability of the main unit chassis. Four fixing nuts 404, welded to the surface of the threaded rod 402 at the upper end of the support leg 403, not only provide a point of leverage for adjusting the height of the support leg 403, but also ensure the firmness of the connection between the fixing nuts 404 and the threaded rod 402 through welding. During frequent height adjustments of the support leg 403, this robust connection effectively prevents the fixing nuts 404 from loosening, ensuring the reliability of the height adjustment operation. This structural design ensures the stability of the support assembly 4 during long-term use, maintaining a stable support state for the main chassis and further improving the reliability of the main chassis under different working environments. Working Principle: First, the user uses an external wrench to rotate the fixing nut 404 located on the surface of the threaded rod 402 and welded to the upper end of the support leg 403. The fixing nut 404 is threadedly connected to the threaded rod 402, so that rotating the fixing nut 404 causes the threaded rod 402 to rotate inside the threaded sleeve 401. The threaded sleeve 401 is installed at the four corners of the lower surface of the support base 1. Through this structure, the rotational motion of the threaded rod 402 is converted into the up-and-down movement of the support leg 403, thereby adjusting the height of the support leg 403. This allows the main unit to better adapt to uneven working surfaces and ensures that the main unit is placed stably. Before using the main unit, the internal equipment needs to be installed. First, multiple suspension brackets 205 are installed on the left and right sides of the inner wall of the U-shaped protective plate 203 using fixing bolt group 204. The tightening action of the fixing bolt group 204 secures the suspension brackets 205 to the U-shaped protective plate 203, providing stable support points for the subsequent support net 206 and related equipment. Then, the support net 206 is installed on the upper end of the suspension brackets 205, providing a platform for the control system of the building sewage equipment. Next, the control system of the relevant building sewage equipment is placed on top of the support net 206, completing the initial placement of the equipment. The filter screen 210 is installed in the filter mounting bracket 209 inside the air inlet 207 and the air outlet 208, respectively. The filter mounting bracket 209 provides a fixed position for the filter screen 210. The filter screen 210 filters the air entering and exiting the main unit through the filter mounting bracket 209, thereby preventing dust and other impurities from entering the main unit and avoiding the discharge of impurities generated by the operation of internal equipment to pollute the environment. After installation, the device is turned on by the controller 3, which is fixedly connected to the lower surface of the inner wall of the outer protective shell 201 on the side of the air inlet 207. When the internal temperature of the outer protective shell 201 is too high, the controller 3 comes into play. The controller 3 regulates the temperature by controlling the exhaust fans 211 inside the air inlet 207 and exhaust 208, as well as the louvers 212 inside the U-shaped protective plate 203 and the square holes 218 on the left and right sides of the outer protective shell 201. The air inlet 207 and exhaust 208 are relatively vertically symmetrical, with the air inlet 207 being larger than the exhaust 208. This chimney-like exhaust design, combined with the operation of the exhaust fan 211, quickly expels the hot air inside the outer protective shell 201. Utilizing the principle of air convection, the heat inside the outer protective shell 201 is carried out, achieving the purpose of reducing the internal temperature. Simultaneously, the U-shaped protective plate 203 is installed inside the U-shaped protective plate 203, making it less likely for related equipment installed on top of the support net 206 to come into contact with the wall of the outer protective shell 201, reducing heat transfer from the outside and further assisting in reducing the internal temperature. When cool air is exhausted into the bottom of the U-shaped protective plate 203 through the exhaust fan 211 inside the air inlet 207, the wavy design of the edge of the U-shaped protective plate 203 begins to function. The wavy edge can quickly cut the air, allowing the air to pass through the inside of the U-shaped protective plate 203 and its left and right sides. Through this zoned airflow guidance, the temperature inside the U-shaped protective plate 203 and the outer protective shell 201 is cooled more evenly, ensuring that the internal temperature of the main unit chassis decreases uniformly and avoiding damage to the equipment due to localized overheating. During the use of the main unit, water often appears in the control system of the building's sewage equipment. To prevent water from entering the outer protective shell 201 and affecting the safety of the equipment installed inside, a series of waterproofing measures are taken. Guiding flow pipes 215 are interwoven inside the support base 1. This design allows water to drain directly from the support base 1 through the guiding flow pipes 215, preventing water accumulation near the support base 1 and thus preventing water buildup from affecting the normal operation of the device. Furthermore, a trapezoidal guide shell 217 is fixedly connected to the lower end of the support base 1. The trapezoidal guide shell 217 effectively separates the directly flowing water, preventing water from causing dampness or other hazards to the support base 1 and the equipment inside the outer protective shell 201, thus protecting the safe operation of the equipment.
