Description

Technical Field

[0001] This utility model relates to the field of water-blocking tools, and more specifically, to a shielding device for a host computer. Background Technology

[0002] In settings such as hospitals and laboratories where equipment stability is paramount, various precision mainframes (such as medical diagnostic mainframes and laboratory analysis mainframes) are core infrastructure ensuring the normal operation of work. These mainframes integrate a large number of electronic components, circuit boards, and precision sensors, and have strict requirements for the humidity and sealing of the working environment. Once liquids enter, they are highly susceptible to short circuits, component corrosion, data loss, and other malfunctions. This not only results in high equipment repair costs but may also delay the diagnosis and treatment process in medical settings due to equipment downtime, posing a potential threat to patients' lives and health. However, some older medical buildings or laboratories often face problems such as aging roof waterproofing layers and pipe leaks during long-term use, especially in rainy or snowy weather or when pipe maintenance is not timely, leading to frequent roof leaks. To prevent water droplets from dripping directly onto the main unit surface, the industry-standard protective method is to cover the top of the main unit with a cloth cover. However, this traditional protective method has significant drawbacks: First, the cloth cover needs to completely wrap around the top of the main unit during the covering process. However, the main unit usually needs to reserve space for heat dissipation or interface operation during operation. Covering the main unit with the cloth cover can easily lead to poor heat dissipation and also hinder medical staff from quickly operating the interfaces on the top of the main unit, affecting the efficiency of equipment use. Second, the unfolding and folding of the cloth cover is cumbersome. Since the size of the cloth cover needs to match the overall specifications of the main unit, it is difficult for a single person to unfold and fix it. It often requires 2-3 medical staff to work together to first hold the cloth cover up and align it with the position of the main unit, and then fix it with ropes or buckles. The operation is time-consuming and laborious. Especially in emergency medical scenarios, the excessively long preparation time for protection will further increase the tension of the workflow. Third, the fixation reliability of the cloth cover is poor. Affected by airflow disturbances or personnel collisions, the cloth cover is prone to displacement and slippage, resulting in protection failure and inability to continuously protect the main unit from the threat of water leakage. Meanwhile, in settings such as hospitals, rooftop pendants (used to suspend medical equipment, oxygen supply pipelines, etc.) are typically installed. While these structures offer stable load-bearing capacity and fixed positions, they haven't been effectively utilized for leak protection of the main unit. Current technology lacks a leak-proof solution that leverages the pendant structure, allows for convenient deployment and retraction, and doesn't interfere with the normal operation of the main unit. Therefore, developing a rooftop leak-proof device for main unit installation that is compatible with pendant installation, easy to operate, and flexibly deployable has become a key requirement for addressing current industry pain points. Utility Model Content

[0003] The purpose of this utility model is to provide a shielding device for the host computer, so as to solve the problems mentioned in the background art, such as the aging of the roof waterproofing layer and pipe leakage in some old medical buildings or laboratories during long-term use, especially the frequent occurrence of roof leakage in rainy or snowy weather or when pipe maintenance is not timely.

[0004] To achieve the above objectives, this utility model provides a shielding device for a host computer, including a shielding structure, an installation component, and an operating component. The installation component is used to detachably install the shielding structure on a ceiling-mounted tower, with the shielding structure positioned directly above the host computer. The shielding structure adopts an umbrella-shaped foldable structure, having an unfolded state and a retracted state. In the unfolded state, the shielding structure forms a shielding surface for catching leaks from the roof; in the retracted state, the shielding structure shrinks into a compact shape. The operating component is electrically connected to the shielding structure, allowing medical personnel standing on the ground to operate the operating component to switch the shielding structure between the unfolded and retracted states.

[0005] This setup utilizes a three-part structural design—a shielding structure, an installation component, and an operating component—to form a complete leak protection system. First, the installation component detachably and securely attaches the shielding structure to the rooftop tower, ensuring it is precisely positioned directly above the main unit, providing a stable support foundation. Second, the shielding structure features an umbrella-shaped, foldable design, allowing for two states: "unfolded" and "folded." When unfolded, it forms a continuous shielding surface to absorb leaks; when folded, it retracts into a compact form to reduce space occupation. Finally, the operating component establishes an electrical connection with the shielding structure, allowing medical personnel to transmit signals from the ground to drive the shielding structure to switch states, eliminating the need for work at heights or multiple personnel.

[0006] Preferably, the shielding structure includes retractable components, shielding cloth, and a central rod; the shielding cloth is wrapped around the outside of the central rod, the top of the central rod is connected to the tower via the mounting components, multiple sets of retractable components are evenly distributed along the circumference of the central rod, the outer end of the retractable components is hinged to the inner side of the shielding cloth, and a slip ring is slidably provided on the central rod, the outer side of the slip ring is hinged to the inner end of the retractable components.

[0007] This shielding structure employs a collaborative design of a central pole, retractable components, and shielding fabric. The central pole, serving as the core support, is connected to the pylon at its top via mounting components, providing a vertical fixation reference for the entire shielding structure. Multiple retractable components are evenly distributed circumferentially along the central pole, forming a symmetrical support frame. Their outer ends are hinged to the shielding fabric, allowing it to expand or contract synchronously. Slip rings on the central pole can slide linearly along the pole and are hinged to the inner ends of the retractable components. The displacement of these slip rings changes the tilt angle and extension length of the retractable components, thereby controlling the unfolded area of ​​the shielding fabric.

[0008] Preferably, the center rod is internally equipped with a lead screw, and a slider is threaded onto the outer side of the lead screw. The outer end of the slider extends through the center rod and is welded to the inner wall of the slip ring. The top of the lead screw is driven by a motor to rotate, thereby driving the slip ring to move linearly up and down, realizing the retraction and expansion of the retraction assembly. The outer shell of the motor is fixedly mounted on the assembly.

[0009] This setup utilizes a "lead screw-slider-motor" transmission structure to power the shielding structure. The lead screw and slider inside the central rod form a helical transmission pair. The slider is welded and fixed to the inner wall of the slip ring, making them move synchronously. The motor is fixed to the mounting assembly, and its output shaft is connected to the top of the lead screw. When the motor runs, it drives the lead screw to rotate, converting the rotational motion of the lead screw into the linear motion of the slider through helical transmission. This, in turn, drives the slip ring to slide along the central rod, and the slip ring then drives the retraction / expansion assembly to complete the retraction or expansion action.

[0010] Preferably, the unfolding assembly includes a first support rod and a second support rod. The outer ends of the first support rod and the second support rod are hinged together. The inner end of the first support rod is hinged to the outer wall of the slip ring. The inner end of the second support rod is hinged to the middle of the inner top of the shielding cloth. The hinge joint of the first support rod and the second support rod is fixed to the middle of the inner wall of the shielding cloth. By moving the slip ring vertically up and down, the first support rod and the second support rod can be folded and stored, thereby causing the shielding cloth to retract.

[0011] This retractable assembly uses a "double-rod hinge" structure. The outer ends of the first and second rods are hinged together to form a foldable movable joint. When the slip ring slides upward along the central rod, it pulls the first rod to rotate around the hinge point, which in turn drives the second rod to rotate synchronously, reducing the angle between the two rods and achieving folding and retraction. At the same time, it drives the inner middle and outer ends of the shielding cloth to retract inward synchronously. When the slip ring slides downward, the angle between the two rods increases, extending outward and pushing the shielding cloth to unfold into a complete shielding surface.

[0012] Preferably, the operating component includes an operating panel and a control cable. The operating panel is electrically connected to the input terminal of the motor via the control cable, and the operating panel is provided with two buttons for controlling the start and stop of the motor.

[0013] This setup establishes a remote control link between the ground and elevated locations. The control panel is electrically connected to the motor input via a control cable, forming a complete control circuit. The two buttons on the control panel correspond to the forward and reverse rotation of the motor. When medical staff press the buttons, the control panel outputs the corresponding electrical signal, which is transmitted to the motor via the control cable to control the motor's direction of rotation and start / stop status, thereby indirectly controlling the retraction and extension of the shielding structure.

[0014] Preferably, the installation assembly includes a U-shaped clamp, a pressure plate is provided on the inner side of the U-shaped clamp, a threaded rod is installed on the back of the pressure plate, a threaded hole is provided on one side wall of the U-shaped clamp, the threaded rod is threadedly connected to the threaded hole, a screw handle is installed on the outer end of the threaded rod, and the U-shaped clamp is clamped and fixed to the ceiling tower on the roof by the pressure plate.

[0015] This installation assembly uses a clamping and fixing structure of "U-shaped clamp + threaded rod + pressure plate". The opening of the U-shaped clamp can be directly engaged with the horizontal or vertical bar of the crane tower to form a preliminary positioning; the threaded hole on one side wall of the clamp engages with the threaded rod. By rotating the screw handle at the outer end of the threaded rod, the threaded rod can be pushed to move axially along the threaded hole, thereby driving the inner pressure plate to move closer to the crane tower until the pressure plate is tightly attached to the surface of the crane tower. Through the clamping force between the pressure plate and the inner wall of the U-shaped clamp, the entire device is fixed to the crane tower.

[0016] Preferably, a silicone pad is installed on the front side of the pressure plate.

[0017] This feature involves installing a silicone pad on the front side where the pressure plate contacts the crane tower. The silicone material has a high coefficient of friction, which increases the friction between the pressure plate and the crane tower surface, improving the stability of the clamping and fixing. At the same time, the silicone is soft and has a certain degree of elasticity, which can fill the tiny gaps between the pressure plate and the crane tower surface, making the contact tighter, and can also buffer the pressure generated during the clamping process.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This shielding device for the main unit utilizes a U-shaped clamping plate and threaded rod in the mounting assembly to quickly clamp and fix it to the ceiling-mounted crane. No additional drilling, welding, or other modifications to the crane or building structure are required. The installation process can be completed by a single person, significantly reducing installation difficulty and construction costs. Furthermore, the silicone pad on the front of the clamping plate not only increases friction with the crane, improving stability, but also prevents scratches caused by direct contact between the clamping plate and the crane surface. It is adaptable to crane structures with different pipe diameters or cross-sectional dimensions, thus broadening its applicability. Single-person ground operation enables folding and unfolding, significantly improving efficiency: Utilizing the electrical signal transmission between the operating components and the shielding structure, medical personnel standing on the ground can control the motor via buttons on the control panel. This drives the lead screw within the central rod, causing the slip ring to move linearly, thus folding and unfolding the folding and unfolding components, ultimately completing the storage and unfolding of the shielding cloth. The entire operation requires no multiple people or climbing to heights; a single person can complete the status switch in just a few seconds. This effectively solves the problems of cumbersome, time-consuming, and labor-intensive folding and unfolding of traditional cloth shields. Especially in emergency medical scenarios, it can quickly respond to leakage protection needs, ensuring the continuous and stable operation of the main unit. The umbrella-shaped folding structure balances protection and space utilization: The umbrella-shaped foldable design, when unfolded, forms a sufficiently large shielding surface precisely positioned above the main unit. It effectively catches rainwater or condensation dripping from the roof, preventing direct liquid contact with the main unit and protecting the delicate internal components from water damage. This provides significantly better protection than traditional cloth covers. In everyday use, when protection is not needed, the structure can be retracted into a compact shape, greatly reducing its size. It doesn't occupy excessive space above the main unit or obstruct heat dissipation, ventilation, or top interface operations, resolving the pain point of traditional cloth covers affecting the use of the main unit and achieving compatibility between protective functions and normal equipment operation. The structure is stable and has a long service life, reducing maintenance costs: The retraction and extension components are hinged together by the first and second support rods, combined with the linear drive of the slip ring, ensuring stable and smooth movement without the risk of jamming or loosening. It can withstand the weight load of the shielding cloth when it is absorbing liquid for a long time. The shielding cloth can be made of waterproof, wear-resistant, and anti-aging polymer materials, which have good waterproof performance and durability, and are not easily damaged or leaked due to long-term exposure to air or liquid. The transmission structure of the motor and lead screw has good sealing, which can effectively prevent malfunctions caused by dust and moisture intrusion. The overall device structure is stable and reliable, reducing the need for frequent maintenance and replacement, and lowering maintenance costs during long-term use. The detachable design facilitates flexible adjustment and relocation, enhancing practicality: Because the mounting components utilize a detachable clamping fixation method, when the main unit's position needs adjustment or the device needs to be moved to another crane tower, simply loosening the threaded rod allows the device to be removed from the tower—a quick and easy operation without damaging the original installation structure. This detachable feature enables the device to flexibly adjust its installation position according to changes in actual usage scenarios, adapting to the protection requirements of different areas and different main unit models, further improving the device's practicality and resource utilization.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a shielding device for a host computer, such as... Figures 1-4 As shown, it includes a shielding structure 1, an installation component 2, and an operating component 3. The installation component 2 is used to detachably install the shielding structure 1 on a ceiling-mounted tower, with the shielding structure 1 located directly above the main unit. The shielding structure 1 adopts an umbrella-shaped foldable structure, having an unfolded state and a retracted state. In the unfolded state, the shielding structure 1 forms a shielding surface to catch water leakage from the roof. In the retracted state, the shielding structure 1 shrinks into a compact shape. The operating component 3 is electrically connected to the shielding structure 1. Medical staff standing on the ground can drive the shielding structure 1 to switch between the unfolded and retracted states by operating the operating component 3.

[0022] In use, a complete leakage protection system is formed through a three-section structural design of "shielding structure 1 + installation component 2 + operation component 3". First, the installation component 2 detachably fixes the shielding structure 1 to the rooftop tower, ensuring that the shielding structure 1 is precisely positioned directly above the main unit, providing a stable support foundation for protection. Second, the shielding structure 1 adopts an umbrella-shaped foldable structure, utilizing its folding characteristics to achieve two states of "unfolding-folding"—when unfolded, it forms a continuous shielding surface to absorb leakage, and when folded, it shrinks into a compact form to reduce space occupation. Finally, the operation component 3 establishes an electrical connection with the shielding structure 1, allowing medical personnel to transmit signals from the ground to drive the shielding structure 1 to complete the state switching, without the need for working at heights or multiple people working together. This structural design addresses the core pain points of traditional fabric covers from a holistic perspective: First, it eliminates the direct wrapping of the host, avoiding impact on host heat dissipation and interface operation; second, the detachable installation of mounting component 2 adapts to tower crane scenarios without requiring modifications to the building structure; third, the operation component 3 enables single-person operation of the cover from the ground, significantly reducing labor costs and operational difficulty. Meanwhile, the umbrella-shaped structure of the shielding structure 1 balances protection area and space utilization, laying the functional framework for subsequent detailed structural designs.

[0023] In this embodiment, the shielding structure 1 includes a retractable assembly 11, a shielding cloth 12, and a central rod 13. The top end of the central rod 13 is connected to the tower via an installation assembly 2. Multiple sets of retractable assemblies 11 are evenly distributed around the circumference of the central rod 13. The outer end of the retractable assembly 11 is hinged to the inner side of the shielding cloth 12. A slip ring 131 is slidably disposed on the central rod 13, and the outer side of the slip ring 131 is hinged to the inner end of the retractable assembly 11. The top end of the central rod 13 passes through the middle of the top inner side of the shielding cloth 12, and the shielding cloth 12 wraps around the outer side of the central rod 13.

[0024] In use, the shielding structure 1 adopts a collaborative structure of "central rod 13 + retractable assembly 11 + shielding cloth 12". The central rod 13 serves as the core support component, and its top end is connected to the tower via the mounting assembly 2, providing a vertical fixing reference for the entire shielding structure 1. Multiple sets of retractable assemblies 11 are evenly distributed around the circumference of the central rod 13, forming a symmetrical support frame. Their outer ends are hinged to the shielding cloth 12, which can drive the shielding cloth 12 to expand or contract synchronously. The slip ring 131 on the central rod 13 can slide linearly along the rod body and is hinged to the inner end of the retractable assembly 11. The displacement of the slip ring 131 changes the tilt angle and extension length of the retractable assembly 11, thereby controlling the unfolded area of ​​the shielding cloth 12. The "expansion and retraction function" of the shielding structure 1 is visualized as an executable mechanical structure. Multiple sets of expansion and retraction components 11 are evenly distributed around the central rod 13 to ensure that the shielding cloth 12 is evenly stressed after being unfolded, avoiding local sagging that could lead to leakage and displacement. The hinged design between the slip ring 131 and the expansion and retraction components 11 makes the expansion and retraction action smoother and eliminates the risk of jamming. At the same time, the supporting role of the central rod 13 ensures that the shielding structure 1 will not tilt due to its own weight or rainwater after being unfolded, thus improving the accuracy of the protective position.

[0025] Specifically, a lead screw is rotatably mounted inside the central rod 13, and a slider is threaded onto the outer side of the lead screw. The outer end of the slider slides through and extends to the outer side of the central rod 13 and is welded and fixed to the inner wall of the slip ring 131. The top of the lead screw is driven to rotate by a motor 132, which in turn drives the slip ring 131 to move linearly up and down, realizing the retraction and expansion of the retraction assembly 11. The outer casing of the motor 132 is fixedly mounted on the assembly 2. A groove is provided on the outer wall of the central rod 13 along the axial direction to facilitate the sliding of the slider.

[0026] In use, a transmission structure of "lead screw-slider-motor 132" is adopted to provide power to the shielding structure 1. The lead screw and slider inside the central rod 13 form a helical transmission pair. The slider is welded and fixed to the inner wall of the slip ring 131, so that the slider and slip ring 131 form a synchronous moving body. The motor 132 is fixed on the mounting assembly 2, and the output shaft is connected to the top of the lead screw. When the motor 132 is running, it drives the lead screw to rotate. Through helical transmission, the rotational motion of the lead screw is converted into the linear motion of the slider, which in turn drives the slip ring 131 to slide along the central rod 13. The slip ring 131 then drives the retraction assembly 11 to complete the retraction or expansion action. This structural design enables automated operation of the shielding structure 1, which is more labor-saving and efficient than traditional manual rope pulling. The spiral drive features high transmission precision and good self-locking. The displacement of the slip ring 131 is precise and controllable, allowing the shielding cloth 12 to remain stably after being unfolded to a specified area, preventing it from sliding due to external forces. The motor 132 is fixed to the mounting component 2, forming a stable power transmission path with the central rod 13, reducing vibration and noise. At the same time, the fixed design of the motor 132 housing improves the overall structural stability and extends its service life.

[0027] Furthermore, the retractable assembly 11 includes a first support rod 111 and a second support rod 112. The outer ends of the first support rod 111 and the second support rod 112 are hinged together. The inner end of the first support rod 111 is hinged to the outer wall of the slip ring 131. The inner end of the second support rod 112 is hinged to the middle of the inner top of the shielding cloth 12. The hinge joint of the first support rod 111 and the second support rod 112 is fixed to the middle of the inner wall of the shielding cloth 12. By the vertical linear movement of the slip ring 131, the first support rod 111 and the second support rod 112 can be folded and stored, thereby causing the shielding cloth 12 to retract.

[0028] In use, the retractable assembly 11 adopts a double-rod hinge structure of "first rod 111 + second rod 112". The outer ends of the first rod 111 and the second rod 112 are hinged to form a foldable movable joint. When the slip ring 131 slides upward along the central rod 13, it will pull the first rod 111 to rotate around the hinge point, which will drive the second rod 112 to rotate synchronously, so that the included angle between the two rods decreases, realizing folding and shrinking. At the same time, it will drive the inner middle part and the outer end of the cover cloth 12 to shrink inward synchronously. When the slip ring 131 slides downward, the included angle between the two rods increases and extends outward, pushing the cover cloth 12 to unfold into a complete cover surface. The folding structure of the first support rod 111 and the second support rod 112 allows the cover cloth 12 to be folded and unfolded more thoroughly. When folded, the cover cloth 12 can be folded into a multi-layered compact shape, reducing the storage volume. When unfolded, the cover cloth 12 can be fully stretched to ensure that the covering surface is flat and wrinkle-free, avoiding water leakage and seepage caused by water accumulation due to wrinkles. The hinge joint of the first support rod 111 and the second support rod 112 and the fixed design of the cover cloth 12 further enhance the connection strength between the cover cloth 12 and the unfolding component 11, preventing the cover cloth 12 from detaching from the support rod when collecting rainwater, and improving the reliability of structure 1.

[0029] Furthermore, the operating component 3 includes an operating panel 31 and a control cable 32. The operating panel 31 is electrically connected to the input terminal of the motor 132 via the control cable 32. The operating panel 31 is provided with two buttons 33 for controlling the start and stop of the motor 132. One button 33 controls the motor 132 to rotate forward, and the other button 33 controls the motor 132 to rotate in reverse.

[0030] In use, the operating component 3 establishes a remote control link between the ground and the height. The operating panel 31 is electrically connected to the input terminal of the motor 132 via the control cable 32, forming a complete control circuit. The two buttons 33 on the operating panel 31 correspond to the forward and reverse rotation of the motor 132. When medical personnel press the buttons 33, the operating panel 31 outputs the corresponding electrical signal, which is transmitted to the motor 132 via the control cable 32 to control the rotation direction and start / stop status of the motor 132, thereby indirectly controlling the retraction and extension of the shielding structure 1. This structural design completely realizes "single-person operation on the ground," eliminating the need for medical personnel to climb to the vicinity of the crane for work and avoiding the risk of falls from heights. The connection method of the control cable 32 in the operating component 3 is more stable than wireless control, is not affected by the complex electromagnetic environment of the hospital, and ensures reliable transmission of control signals. The buttons 33 on the operating panel 31 are designed to be simple and intuitive, allowing medical personnel to quickly get started without professional training. Especially in emergency water leakage scenarios, it can quickly respond to operational needs and shorten the preparation time for protection.

[0031] Furthermore, the mounting assembly 2 includes a U-shaped clamp 21, with a pressure plate 23 on the inner side of the U-shaped clamp 21. A threaded rod 22 is mounted on the back of the pressure plate 23. A threaded hole is provided on one side wall of the U-shaped clamp 21, and the threaded rod 22 is threadedly connected to the threaded hole. A screw handle 24 is mounted on the outer end of the threaded rod 22. The U-shaped clamp 21 is clamped and fixed to the ceiling tower on the roof by the pressure plate 23. The housing of the motor 132 is mounted on the inner bottom wall of the U-shaped clamp 21.

[0032] In use, the installation component 2 adopts a clamping and fixing structure of "U-shaped clamp 21 + threaded rod 22 + pressure plate 23". The opening of the U-shaped clamp 21 can be directly engaged with the horizontal or vertical bar of the crane tower to form a preliminary positioning; the threaded hole on one side wall of the U-shaped clamp 21 cooperates with the threaded rod 22. By rotating the screw handle 24 at the outer end of the threaded rod 22, the threaded rod 22 can be pushed to move axially along the threaded hole, thereby driving the inner pressure plate 23 to move closer to the crane tower until the pressure plate 23 is tightly attached to the surface of the crane tower. Through the clamping force between the pressure plate 23 and the inner wall of the U-shaped clamp 21, the entire device is fixed on the crane tower. This structural design enables the device to be detachably and quickly fixed to the tower. The installation process does not require drilling or welding, thus avoiding damage to the tower structure. The design of the screw handle 24 at the outer end of the threaded rod 22 allows medical staff to install or remove the installation component 2 without the need for tools, making the operation convenient. The clamping and fixing of the U-shaped clamp 21 and the pressure plate 23 are compatible with tower rods of different diameters, with a wide range of applications. At the same time, the clamping force can be adjusted by the screwing force to ensure stable fixation and prevent the device from shifting due to vibration or wind.

[0033] Furthermore, a silicone pad 231 is installed on the front side of the pressure plate 23.

[0034] In use, a silicone pad 231 is installed on the front side of the mounting component 2 where the pressure plate 23 contacts the crane tower. The physical properties of silicone are utilized: silicone has a high coefficient of friction, increasing the friction between the pressure plate 23 and the crane tower surface, thus improving the stability of the clamping and fixing; simultaneously, silicone is soft and elastic, filling the tiny gaps between the pressure plate 23 and the crane tower surface, making the contact tighter, and buffering the pressure generated during clamping. This provides dual protection for the crane tower and the device: firstly, it prevents direct hard contact between the pressure plate 23 and the crane tower's metal surface, preventing scratches and damage to the crane tower and protecting its appearance and structural integrity; secondly, the silicone pad 231 enhances the clamping stability of the mounting component 2. Even if the crane tower surface has slight rust or unevenness, the silicone pad 231 can adapt through deformation, preventing the device from loosening due to insufficient contact; furthermore, silicone is resistant to aging and wear, and long-term use will not affect the protective effect due to material deterioration, extending the service life of the mounting component 2.

[0035] The steps for using the shielding device for the host computer according to this utility model are as follows: 1. Installation and fixing stage Step 1: Locate the installation position: Medical staff observe the location of the main unit and the distribution of the ceiling-mounted towers, determine the installation point on the tower that corresponds directly above the main unit, and ensure that the shielding structure 1 can completely cover the top of the main unit after it is unfolded. Step 2: Fixing the mounting assembly 2: Engage the opening of the U-shaped clamp 21 of the mounting assembly 2 onto the tower rod, so that the inner wall of the U-shaped clamp 21 fits against the surface of the tower; then turn the screw handle 24 clockwise, causing the threaded rod 22 to move along the threaded hole of the U-shaped clamp 21 toward the tower. The threaded rod 22 pushes the pressure plate 23 closer to the tower until the silicone pad 231 on the front of the pressure plate 23 fits tightly against the tower. The clamping force fixes the U-shaped clamp 21 to the tower. At this time, the center rod 13 is connected to the tower through the mounting assembly 2 and is suspended vertically above the main unit. 2. Deploy the protection phase Step 1: Start the unfolding operation: Medical staff hold the operation panel 31 on the ground and press the "unfold" button 33 on the panel; after receiving the command, the operation panel 31 outputs a positive electrical signal, which is transmitted to the motor 132 via the control line 32. Step 2: Drive the slip ring 131 to move downward: After receiving a positive electrical signal, the motor 132 starts to rotate forward, driving the lead screw inside the center rod 13 to rotate clockwise; the lead screw is threadedly engaged with the slider, and when the lead screw rotates, it pushes the slider to slide downward along the inner wall of the center rod 13. The slider is welded and fixed to the slip ring 131, so the slip ring 131 moves downward synchronously with the slider. Step 3: Unfolding the shielding cloth 12: When the slip ring 131 moves down, it pulls the first support rod 111, which is hinged to it, to rotate downward around the hinge point. The first support rod 111 pushes the second support rod 112 to rotate synchronously, so that the angle between the first support rod 111 and the second support rod 112 gradually increases. Since the hinge of the two support rods is fixed in the middle of the inner side of the shielding cloth 12, and the outer end of the second support rod 112 is hinged to the top center of the inner side of the shielding cloth 12, the two support rods extend outward as the angle increases, gradually expanding the shielding cloth 12 from a compact state until the shielding cloth 12 is fully unfolded to form a circular shielding surface, covering the area directly above the main unit. Step 4: Maintain protective status: Medical staff observe the unfolding status of the protective cloth 12. After confirming that it completely covers the main unit, they release the "unfold" button 33, and the motor 132 stops running. Due to the self-locking property of the screw and slider screw transmission, the slip ring 131 can stay stably in the current position, and the protective cloth 12 remains unfolded. Rainwater dripping from the roof falls on the protective cloth 12 and drips along the edge of the protective cloth 12 to the ground, avoiding direct contact with the main unit. 3. Storage during the idle period Step 1: Initiate the storage operation: When the roof leak problem is resolved or protection is no longer needed, medical staff press the "Storage" button 33 on the control panel 31; the control panel 31 outputs a reverse electrical signal, which is transmitted to the motor 132 via the control line 32. Step 2: Drive the slip ring 131 upward: After receiving the reverse electrical signal, the motor 132 starts to reverse, driving the lead screw to rotate counterclockwise. Under the action of the lead screw, the slider slides upward along the inner wall of the central rod 13, and the slip ring 131 moves upward synchronously with the slider. Step 3: Retracting the shielding cloth 12: When the slip ring 131 moves upward, it pulls the first support rod 111 to rotate upward around the hinge point. The first support rod 111 pulls the second support rod 112 to rotate synchronously, so that the included angle between the two support rods gradually decreases. The two support rods fold towards the center rod 13, causing the inner middle and outer ends of the shielding cloth 12 to retract towards the center. The shielding cloth 12 gradually folds into a multi-layered compact shape and fits against the outside of the center rod 13. Step 4: Complete the storage and idle state: When the cover cloth 12 is completely retracted to a tight state with no obvious loose parts, the medical staff release the "storage" button 33, the motor 132 stops running, the slip ring 131 stays stably at the upper position of the center rod 13, the device enters the idle state, does not occupy the space above the host, and does not affect the heat dissipation and interface operation of the host.
