Description

Technical Field

[0001] This utility model relates to the field of outdoor monitoring cabinet technology, and in particular to an outdoor waterproof monitoring cabinet. Background Technology

[0002] A server rack is a cabinet structure designed to house and install electronic equipment as needed. A monitoring server rack is an outdoor enclosure that houses monitoring electronic equipment such as switching systems and power systems, providing a suitable environment and security for the normal operation of the electronic equipment. This is the second-highest level of assembly after the system level. The structure of the server rack should be designed physically and chemically according to the electrical and mechanical performance requirements of the equipment and the operating environment to ensure good rigidity and strength, as well as good electromagnetic isolation, grounding, noise isolation, ventilation, and heat dissipation. To ensure comprehensive functionality, server racks typically house numerous high-value electronic devices, including monitoring equipment, data acquisition units, access units, and batteries.

[0003] Currently, conventional monitoring cabinets have ventilation holes on the sides to improve the heat dissipation and efficiency of the electronic equipment inside, thereby reducing the operating temperature of the electronic equipment and preventing overheating damage. Monitoring cabinets are typically placed outdoors to meet practical needs. To ensure effective heat dissipation, the air intake vents are usually positioned low, utilizing the automatic rising characteristics of heat-absorbing gas to promote directional airflow within the cabinet, effectively cooling the built-in electronic equipment. However, existing monitoring cabinets have poor waterproofing capabilities and cannot adjust their installation height according to changes in ambient water levels. With increasing global warming, the probability and severity of severe weather have increased. During heavy rainstorms, outdoor monitoring cabinets located in low-lying areas are highly susceptible to water intrusion due to rising water levels. Rising water can easily enter the cabinet cavity through the ventilation holes at the bottom and assembly gaps, causing short circuits in electrical equipment, insulation aging and burnout of electrical coils and leads, and affecting the stability and safety of the electronic equipment. Utility Model Content

[0004] The purpose of this invention is to provide an outdoor waterproof monitoring cabinet that can adaptively adjust the cabinet height according to changes in water level to prevent water seepage and improve the cabinet's waterproof capability. This solves the problem that existing monitoring cabinets placed in low-lying areas are prone to being lowered below the water level during heavy rainstorms due to increased environmental water accumulation. They cannot automatically adjust their height according to changes in water level, leading to water intrusion and short circuits in the internal electronic components.

[0005] The technical solution adopted by this utility model is as follows: an outdoor waterproof monitoring cabinet, including a cabinet shell, and a sensor lifting frame at the bottom of the cabinet shell that can adjust the placement height of the cabinet shell according to the water level. The sensor lifting frame is supported on a base. The sensor lifting frame includes a mounting frame, a telescopic adjustment mechanism arranged at intervals around the corners of the mounting frame, a two-position switch mechanism embedded in the mounting frame, and a unit switch mechanism disposed outside the telescopic adjustment mechanism. The two-position switch mechanism can cooperate with the unit switch mechanism to form a parallel bidirectional electrical circuit to control the telescopic movement of the telescopic adjustment mechanism.

[0006] According to a preferred embodiment, the support tube of the telescopic adjustment mechanism is supported on the base. The top end of the support tube is rotatably threaded with a plug screw. The outside of the support tube is also fitted with a protective shell that can move up and down along its cylindrical axis and is connected to the mounting frame. The top of the protective shell is equipped with a telescopic adjustment motor, and the power shaft of the telescopic adjustment motor passes through the top surface of the protective shell and is connected to the top end of the plug screw inside the protective shell.

[0007] According to a preferred embodiment, the dual-position switch mechanism includes a first switch housing, a first switch element, a second switch element, and a first buoyancy adjustment element. The first switch housing is embedded in a mounting frame, and the top and bottom of the cavity of the first switch housing are respectively provided with a first switch element and a second switch element connected in parallel. The first buoyancy adjustment element can also be vertically inserted into the cavity of the first switch housing.

[0008] According to a preferred embodiment, the first conductive plate and the second conductive plate of the first switch element are aligned and inserted into the inner wall of the top cavity of the first switch housing, and an upper conductive connecting plate is also provided on the inner top surface of the first switch housing via a connecting spring.

[0009] According to a preferred embodiment, the third and fourth conductive plates of the second switch element are aligned and inserted into the inner wall of the bottom cavity of the first switch housing, and a lower conductive connecting plate is movably disposed on the inner bottom surface of the first switch housing.

[0010] According to a preferred embodiment, the first buoyancy adjustment member includes a magnetically adjustable block disposed inside the first switch housing and capable of being raised and lowered, a linkage vertical rod penetrating the bottom of the first switch housing and connected to the magnetically adjustable block, and a first buoyancy plate disposed below the first switch housing and connected to the lower axial end of the linkage vertical rod.

[0011] According to a preferred embodiment, a left-hand conductive plate and a right-hand conductive plate are inserted into the limiting post housing of the unit switch mechanism. The limiting post housing is also provided with an abutting conductive block that can move up and down. The abutting conductive block is connected to a second buoyancy plate located below the limiting post housing via a connecting rod that passes through the limiting post housing.

[0012] According to a preferred embodiment, a top cover that can be detachably fastened to the telescopic adjustment motor is also provided on the top of the protective cylinder shell, and a sizing rectangular washer that can fill the sleeve gap between the protective cylinder shell and the supporting square tube is also embedded on the inner wall surface of the lower opening of the protective cylinder shell.

[0013] The beneficial effects of this utility model are:

[0014] The electrical circuit established by the dual-position switch mechanism and the unit switch mechanism in this application can adaptively close or open according to changes in water level. This allows the telescopic adjustment mechanism to extend or shorten under current in different directions, changing the actual support height of the induction lifting frame. This ensures that the cabinet is always positioned above the water level, preventing water leakage and ensuring that the internal electronic equipment does not come into contact with water, thus improving the waterproof capability of the electronic equipment and guaranteeing the stable operation of the monitoring cabinet in severe weather. Furthermore, the descent of the telescopic adjustment mechanism when the water level drops also helps maintain the cabinet's low center of gravity, improving the overall structural stability and ease of maintenance.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] The technical solutions provided by this utility model will be described in detail below with reference to the accompanying drawings and through embodiments. It should be noted that the descriptions of these embodiments are for the purpose of helping to understand this utility model, but do not constitute a limitation thereof. In some examples, because some implementation methods belong to existing or conventional technology, they are not described or are not described in detail. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and do not have any sequential or technical meaning.

[0024] The following is a detailed explanation with reference to the accompanying drawings.

[0025] Example 1

[0026] This application provides an outdoor waterproof monitoring cabinet, which includes a cabinet shell 1, an induction lifting frame 2, and a base 3.

[0027] according to Figure 1-5In one specific embodiment, the cabinet 1 forms a housing structure for isolating and housing electronic equipment. An inductive lifting frame 2, adjustable in height according to water level, is located at the bottom of the cabinet 1. The inductive lifting frame 2 is supported on a concrete base 3. The base 3 can be a pre-cast concrete platform with multiple expansion bolts pre-installed on its surface for easy connection to the bottom flange of the inductive lifting frame 2. The inductive lifting frame 2 includes a mounting frame 21, telescopic adjustment mechanisms 22 spaced around the corners of the mounting frame 21, a two-position switch mechanism 23 embedded in the mounting frame 21, and a unit switch mechanism 24 located outside the telescopic adjustment mechanism 22. The cabinet 1 is mounted on the mounting frame 21 by bottom connecting bolts or welding. The two-position switch mechanism 23 and the unit switch mechanism 24 cooperate to form two parallel circuits with opposite current directions, allowing the formed positive or negative electrical loops to be connected as needed, thereby controlling the telescopic movement of the telescopic adjustment mechanism 22. The upper switch body of the double-position switch mechanism 23 is connected in series with the unit switch mechanism 24 and forms a first electrical circuit with the positive power supply and the telescopic adjustment mechanism 22. When both are closed, the first electrical circuit is activated, causing the telescopic adjustment mechanism 22 to extend and raise the height of the cabinet 1. The lower switch body of the double-position switch mechanism 23 forms a second electrical circuit with the reverse power supply and the telescopic adjustment mechanism 22. When the lower switch body is closed, the retraction circuit is activated, causing the telescopic adjustment mechanism 22 to shorten and lower the height of the cabinet 1. The electrical circuit formed by the double-position switch mechanism 23 and the unit switch mechanism 24 can adaptively close or open according to changes in water level, allowing the telescopic adjustment mechanism 22 to extend or shorten under current in different directions. This changes the actual support height of the induction lifting frame 2, ensuring that the cabinet 1 is always positioned above the water level, preventing water intrusion and ensuring that the internal electronic equipment does not come into contact with water. This enhances the water resistance of the electronic equipment and ensures the stable operation of the monitoring cabinet in adverse weather conditions. Furthermore, the telescopic adjustment mechanism 22 can easily maintain the low center of gravity of the cabinet when the water level drops, thus improving the overall structural stability and ease of maintenance.

[0028] Preferably, the telescopic adjustment mechanism 22 includes a supporting square tube 221, an insert screw 222, a protective cylindrical shell 223, a telescopic adjustment motor 224, a top cover 225, and a gap-filling rectangular washer 226. Preferably, the supporting square tube 221 of the telescopic adjustment mechanism 22 is supported on the base 3. Preferably, the top end of the supporting square tube 221 is rotatably threaded with the insert screw 222. More preferably, the supporting square tube 221 is also fitted with a protective cylindrical shell 223 that can move up and down along its cylindrical axis and is connected to the mounting connecting frame 21. Preferably, the top of the protective cylindrical shell 223 is equipped with the telescopic adjustment motor 224. Preferably, the telescopic adjustment motor 224 is a ZGA37 series brushed DC geared motor capable of rotating at low speed and high torque in either the forward or reverse direction according to the current direction of the connected circuit. Specifically, the power shaft of the telescopic adjustment motor 224 passes through the top surface of the protective cylinder shell 223 and is connected to the top end of the insert screw 222 inside the protective cylinder shell 223. This allows the telescopic adjustment motor 224 to rotate forward or backward depending on the circuit's energization, driving the insert screw 222 to rotate synchronously and changing its threaded insertion length in the support square tube 221. The protective cylinder shell 223 and the telescopic adjustment motor 224 rise and fall synchronously with the insert screw, thereby changing the support height of the telescopic adjustment mechanism 22. Preferably, a top cover 225 is detachably attached to the telescopic adjustment motor 224 at the top of the protective cylinder shell 223. Preferably, the top cover 225 can be threaded onto a reduced cylindrical shell at the top of the protective cylinder shell 223, and the outer wall of this cylindrical shell has external threads. Specifically, the protective cylinder shell 223 has a rectangular cavity inside, adapted to fit the support square tube 221. Preferably, a breathable dustproof net is installed on the side of the top cover 225, and a rainproof eave is provided at the top of the breathable dustproof net. Preferably, a connecting flange ring matching the top surface of the protective cylinder 223 is provided at the bottom edge of the top cover 225, thereby ensuring the effectiveness of the connection between the top cover 225 and the protective cylinder 223 by bolts passing through the connecting flange ring. A caulking rectangular washer 226 is also embedded in the inner wall of the lower opening of the protective cylinder 223 to fill the sleeve gap between it and the supporting square tube 221.

[0029] Preferably, the dual-position switch mechanism 23 includes a first switch housing 231, a first switch element 232, a second switch element 233, and a first buoyancy adjustment element 234. Preferably, the first switch housing 231 is embedded in the mounting connecting frame 21. Preferably, the top and bottom of the cavity of the first switch housing 231 are respectively provided with the first switch element 232 and the second switch element 233 connected in parallel. Preferably, the first buoyancy adjustment element 234 can also be vertically inserted into the cavity of the first switch housing 231. Preferably, the first switch element 232 is arranged in series with the unit switch mechanism 24, so that when both are closed, the telescopic adjustment motor 224 is driven to rotate forward, causing the rod of the insertion screw 222 to rotate out of the support square tube 221, thereby raising the support height. Preferably, the second switch element 233 can be closed under the control of the descending first buoyancy adjustment element 234, thereby driving the telescopic adjustment motor 224 to rotate in reverse, causing the rod of the insertion screw 222 to rotate into the support square tube 221, thereby lowering the support height.

[0030] Preferably, an insulating film 2311 is provided inside the first switch housing 231 to separate the placement space of the first switch element 232 and the second switch element 233 from the placement space of the magnetic adjustment block 2341. Preferably, a guide sleeve 2312 is also provided at the bottom of the first switch housing 231, which is sleeved on the linkage rod 2342 and limits the movement direction of the linkage rod 2342. Preferably, the lower conductive connecting plate 2333 is movably fitted onto the guide sleeve 2312.

[0031] Preferably, the first conductive piece 2321 and the second conductive piece 2322 of the first switching element 232 are aligned and inserted into the inner wall of the top cavity of the first switch housing 231. Preferably, an upper conductive connecting plate 2323 is also provided on the inner top surface of the first switch housing 231 via a connecting spring 2324. Preferably, the upper conductive connecting plate 2323 includes conductive connecting pieces, an insulating plate, and a magnetic plate that are stacked in sequence, wherein the magnetic plate is connected to the connecting spring 2324. Preferably, the first conductive piece 2321 is connected to the right-side conductive piece 243 via a wire, the second conductive piece 2322 is connected to the terminal of the telescopic adjustment motor 224 via a wire connected in series with a positive power supply, and the left-side conductive piece 242 is also connected to another terminal of the telescopic adjustment motor 224 via a wire, thereby forming a first electrical circuit with the first switching element 232, the unit switching mechanism 24, the positive power supply, and the telescopic adjustment motor 224.

[0032] Preferably, the third conductive piece 2331 and the fourth conductive piece 2332 of the second switching element 233 are aligned and inserted into the inner wall of the bottom cavity of the first switch housing 231. Preferably, a lower conductive connecting plate 2333 is also movably disposed on the inner bottom surface of the first switch housing 231. Preferably, the lower conductive connecting plate 2333 also includes conductive connecting pieces, an insulating plate, and a magnetic plate that are stacked and assembled in sequence. Preferably, the third conductive piece 2331 is connected to the power terminal of the telescopic adjustment motor 224 through a wire connected in series with a reverse power supply, and the fourth conductive piece 2332 is connected to another power terminal of the telescopic adjustment motor 224 through a wire, thereby forming a second electrical circuit with the third conductive piece 2331, the fourth conductive piece 2332, the reverse power supply, and the telescopic adjustment motor 224.

[0033] Preferably, the first buoyancy adjustment component 234 includes a magnetically adjustable block 2341 that is disposed within the first switch housing 231 and is liftable, a linkage vertical rod 2342 that passes through the bottom of the first switch housing 231 and is connected to the magnetically adjustable block 2341, and a first buoyancy plate 2343 disposed below the first switch housing 231 and connected to the axial lower end of the linkage vertical rod 2342. Specifically, the magnetically adjustable component 2341 is a permanent magnet with selectable magnetic force, and the first buoyancy plate 2343 is a high-buoyancy board structure such as foam board.

[0034] More preferably, the first buoyancy plate 2343 can rise or fall synchronously according to changes in water level, thereby changing the working height of the magnetic adjustment block 2341 in a linked manner, so that it can selectively close the first switch 232 or the second switch 233.

[0035] Preferably, the unit switch mechanism 24 includes a limiting post housing 241, a left conductive piece 242, a right conductive piece 243, an abutting conductive block 244, a connecting rod 245, and a second buoyancy plate 246. Preferably, the left conductive piece 242 and the right conductive piece 243, capable of connecting circuit wires, are respectively inserted and aligned within the limiting post housing 241 of the unit switch mechanism 24. Preferably, the limiting post housing 241 also includes an abutting conductive block 244 that can move up and down to adjust and connect the left conductive piece 242 and the right conductive piece 243. More preferably, the abutting conductive block 244 is connected to the second buoyancy plate 246 located below the limiting post housing 241 via the connecting rod 245 passing through the limiting post housing 241, so that the second buoyancy plate 246 can drive the abutting conductive block 244 to move up and down according to the buoyancy of the water level. Specifically, the second buoyancy plate 246 is made of the same foam board. Preferably, the bottom side of the limiting column housing 241 is also provided with a drain hole for draining accumulated water. Preferably, the four telescopic adjustment motors 224 provided in this application are all connected in series in the same electrical circuit. Therefore, the unit switch mechanism 24 only needs to be set on the outside of one protective cylinder housing 223 to realize the linkage of the four motors. Thus, only one unit switch mechanism 24 needs to be set in the entire equipment, and there is no need to set up additional unit switch mechanisms 24 with the three support structures.

[0036] Preferably, the telescopic adjusting motor 224 provided in this application is connected to two parallel batteries for adjustable driving. More preferably, the telescopic adjusting motor 224, batteries, and other electrical components involved in this application are all electrically connected to a controller and a power supply. The control method in this application is achieved through a controller, whose control circuit can be easily programmed by those skilled in the art. The power supply is also common knowledge in the field. Furthermore, this utility model is only used to protect the mechanical device and its mechanical structural features; therefore, the control method and circuit connections will not be explained in detail here.

[0037] For surface connections between components not explicitly specified in this application, conventional bolt connections, snap-fit ​​connections, or fixed connections such as welding can be used. As these are conventional connection methods, this application will not elaborate further on this part. Specifically, the connecting ends of the assembled components all form flange structures, and the two flange structures are connected by bolts, gaskets, or other structures.

[0038] The working principle of this application is as follows:

[0039] When the water level rises, the first buoyancy plate 2343 begins to float upwards with the water level change, causing the magnetic adjustment block 2341 to gradually rise and abut against the insulating film 2311 provided on the lower surface of the first conductive sheet 2321 and the second conductive sheet 2322. At this time, as the magnetic adjustment block 2341 approaches the upper conductive connecting plate 2323, it generates a magnetic attraction force on the magnetic plate of the upper conductive connecting plate 2323, causing the upper conductive connecting plate 2323 to descend. As a result, the two ends of the conductive connecting piece of the upper conductive connecting plate 2323 press against the first conductive sheet 2321 and the second conductive sheet 2322 respectively, thereby realizing the closure of the switch body formed by the first switching element 232. When the water level rises further and contacts the unit switch mechanism 24, the second buoyancy plate 246 rises with the water level, thereby causing the contact conductive block 244 to rise in the limiting column shell 241. This causes the two ends of the contact conductive block 244 to contact the left connecting conductive piece 242 and the right connecting conductive piece 243 respectively, closing the switch body formed by the unit switch mechanism 24 and thus completely closing the first electrical circuit. At this time, the positive power supply drives the telescopic adjustment motor 224 to rotate in the positive direction, causing the insert screw 222 to rotate and move out of the support square tube 221, thereby raising the support height defined by the telescopic adjustment mechanism 22. In this state, the raising process is continuous. Only when the second buoyancy plate 246 of the unit switch mechanism 24 gradually falls off the surface of the accumulated water does the unit switch mechanism 24 disconnect, at which point the first electrical circuit is broken, and the telescopic adjustment mechanism 22 stops raising. When the water level rises further, the unit switch mechanism 24 synchronously and adaptively closes and opens, ensuring that the support height defined by the telescopic adjustment mechanism 22 is always higher than the water level to prevent the cabinet from being intruded by accumulated water.

[0040] When the water level remains constant or drops, the unit switch mechanism 24 remains open. Then, as the water level drops further, the first buoyancy plate 2343 descends. At this time, the distance between the magnetic adjustment block 2341 and the magnetic plate of the upper conductive connecting plate 2323 increases, causing the magnetism between them to decrease. As a result, the wire connecting plate 2323 moves upward under the restoring force of the connecting spring 2324, and the conductive connecting piece of the upper conductive connecting plate 2323 separates from the first conductive piece 2321 and the second conductive piece 2322, causing the first switch 232 to also disconnect. As the water level drops further, the magnetic adjustment block 2341 comes into contact with the insulating film 2311 above the third conductive sheet 2331 and the fourth conductive sheet 2332 of the second switch 233. This causes the magnetic adjustment block 2341 to generate a magnetic attraction force on the magnetic plate of the lower conductive connecting plate 2333, thereby pulling the lower conductive connecting plate 2333 upward. This causes the two ends of the conductive connecting piece of the lower conductive connecting plate 2333 to abut against the lower surface of the third conductive sheet 2331 and the fourth conductive sheet 2332. The second switch 233 closes, thus closing the second electrical circuit. This causes the telescopic adjustment motor 224 to rotate in the opposite direction under the drive of the reverse power supply, causing the insertion screw 222 to rotate and move into the support square tube 221, thereby reducing the support height limited by the telescopic adjustment mechanism 22. During the continuous descent, the first buoyancy plate 2343 gradually comes into contact with the base 3 as the liquid level drops, causing the magnetic adjustment block 2341 to be lifted to a certain height. This releases the magnetic attraction of the magnetic adjustment block 2341 to the lower conductive connecting plate 2333, causing the lower conductive connecting plate 2333 to fall back under the action of gravity. As a result, the second switch 233 is disconnected. At this time, both the first and second electrical circuits remain disconnected, allowing the cabinet to maintain a low support height when there is no or little water accumulation. This facilitates equipment maintenance by operators, reduces the space occupied by the equipment, lowers the center of gravity of the cabinet, and improves the structural stability of the equipment installation.
