Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic engineering construction, and particularly relates to a protection system and method for the entrance of a hydraulic structure and a hydraulic structure. Background Art

[0002] The existing rat guards in hydraulic engineering construction are mainly used to prevent rats and other small pests from entering the building. Especially in remote places such as sluices, pumping stations, power stations, etc., due to their remote locations and different environments from cities, human activities are mostly concentrated indoors, resulting in an environment with food residues, which is likely to attract rodents such as rats into the building. They may enter large electrical equipment or mechanical equipment such as high and low voltage cabinets and pump rooms inside the building, causing impacts or damages. Installing a rat guard at the entrance of such buildings is to create a physical barrier to prevent rats from passing through, while minimizing the impact on personnel passage.

[0003] Rat guards are usually made of strong and durable materials such as stainless steel, aluminum, or special hard plastics. These materials are selected because they can resist the biting and scratching of rats and prevent rats from passing through. In terms of design, the thickness and height of the rat guard need to meet certain requirements to prevent small animals from squeezing through the gaps under or beside the door, while reducing the impact on human passage. However, fixed rat guards are extremely likely to induce the following problems:

[0004] Affect operation obstacles and personnel passage. The fixed rat guard may be located at the bottom of the door and often constitutes an obstacle in height, which is particularly inconvenient for hydraulic workers using wheelchairs or carrying carts. Especially during maintenance, equipment and parts handling, it is necessary to temporarily remove the existing rat guard, and often forget to reinstall it after removal, creating a safety hazard. In high-traffic areas during commuting, rat guards that need to be frequently opened and closed significantly increase the passage time and labor intensity. Especially during peak hours, such delays may lead to congestion and dissatisfaction.

[0005] In case of an emergency such as a fire or other events that require rapid evacuation, the fixed rat guard may block the escape route and increase the escape time. If the rat guard is not properly designed, sharp edges or protruding parts may cause cuts or tripping to the passing personnel.

[0006] Limited adaptability. Fixed rat guards may not be able to completely block all rats in certain situations, especially for rats of different sizes and flexibilities, and their effects may be limited.

[0007] Difficult to maintain and poor in durability. The rat guard needs to be regularly inspected and maintained to ensure its structural integrity and normal function. In outdoor environments, the rat guard may degenerate rapidly due to weather conditions (such as rain, snow, and ultraviolet radiation). Frequent physical contact (such as being kicked or pushed) may cause the rat guard to deform or be damaged, which not only requires repair or replacement but may also lose its rat-proof function during the damage period.

[0008] Poor in aesthetics and design adaptability. The rat guard may be made of metal or other industrial materials, which are often not in harmony with the aesthetic design of the building, especially in historical buildings or places where a certain appearance needs to be maintained. The size and shape of the rat guard may not be suitable for all types of doors or entrances, especially non-standard-sized or specially designed doors, and customized solutions are required, which may increase costs and implementation difficulties.

[0009] Therefore, in hydraulic engineering buildings, how to block the entry of rats and prevent related power equipment from being damaged while ensuring the smooth passage of pedestrians is a problem that needs to be solved. Summary of the Invention

[0010] In view of this, the embodiments of the present application provide a protection system, method, and hydraulic structure for the entrance of a hydraulic structure to solve the problem that existing hydraulic engineering buildings cannot block the entry of rats and prevent related power equipment from being damaged while ensuring the smooth passage of pedestrians.

[0011] The first aspect of the embodiments of the present application provides a protection system for the entrance of a hydraulic structure, including:

[0012] A first sensing area, arranged outside the entrance, including a first pressure sensor array;

[0013] A second sensing area, arranged between the entrance and the first sensing area and connected to the first sensing area, including a liftable barrier mechanism and a second pressure sensor array;

[0014] A signal processing unit, with its input end connected to the output ends of the first pressure sensor array and the second pressure sensor array, and its output end communicatively connected to the input end of the liftable barrier mechanism;

[0015] The signal processing unit is configured to control the lifting of the liftable barrier mechanism based on the pressure signals of the first pressure sensor array and / or the second pressure sensor array;

[0016] The liftable barrier mechanism is configured to have a raised state and a lowered state. In the raised state, the liftable barrier mechanism is close to and protrudes from the ground, and in the lowered state, the liftable barrier mechanism is embedded in the ground.

[0017] The second aspect of the embodiments of the present application provides a method for protecting the entrance of a hydraulic structure, which is applied to the hydraulic structure entrance protection system provided by the first aspect of the embodiments of the present application, and includes:

[0018] Identifying a trigger signal through pressure sensing data;

[0019] In response to the trigger signal, controlling the liftable barrier mechanism to perform a lift state conversion.

[0020] The third aspect of the embodiments of the present application provides a hydraulic structure, and a hydraulic structure entrance protection system provided by the first aspect of the embodiments of the present application is configured at the entrance.

[0021] The hydraulic structure entrance protection system provided by the first aspect of the embodiments of the present application includes a first sensing area disposed outside the entrance and including a first pressure sensor array; a second sensing area disposed inside the entrance and connected to the first sensing area, including a liftable barrier mechanism and a second pressure sensor array; a signal processing unit, the input end of which is connected to the output ends of the first pressure sensor array and the second pressure sensor array, and the output end of which is communicatively connected to the input end of the liftable barrier mechanism; the signal processing unit is configured to control the lifting of the liftable barrier mechanism based on the pressure signals of the first pressure sensor array and / or the second pressure sensor array. By setting up a cooperative detection architecture with internal and external dual sensing areas, all-round pressure monitoring of the entrance area is achieved. The first pressure sensor array performs preliminary identification, the second pressure sensor array continuously tracks the objects that have entered the entrance, and combined with the two-way data integration ability of the signal processing unit, a dynamic response mechanism is formed. This hierarchical detection system can effectively distinguish pressure signals from different sources, avoid false triggering problems of a single sensor, and at the same time improve the system judgment accuracy through the joint analysis of pressure signals, ensuring the timeliness and accuracy of the lift control of the barrier mechanism.

However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details.

[0031] It should also be understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] In addition, in the description of the specification and appended claims of the present application, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0033] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that specific features, structures or characteristics described in connection with that embodiment are included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in some other embodiments", "in still some other embodiments" etc. that appear at different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0034] As Figure 1 shown, an entrance protection system for hydraulic structures provided by an embodiment of this application includes:

[0035] A first sensing area 1, arranged outside the entrance, including a first pressure sensor array 111;

[0036] A second sensing area 2, arranged between the entrance and the first sensing area 1 and connected to the first sensing area 1, including a liftable barrier mechanism 24 and a second pressure sensor array 221;

[0037] A signal processing unit 5, with its input end connected to the output ends of the first pressure sensor array 111 and the second pressure sensor array 221, and its output end communicatively connected to the input end of the liftable barrier mechanism 24;

[0038] The signal processing unit 5 is configured to control the lifting of the liftable barrier mechanism 24 based on the pressure signals of the first pressure sensor array 111 and / or the second pressure sensor array 221;

[0039] The liftable barrier mechanism 24 is configured to have a raised state and a lowered state. In the raised state, the liftable barrier mechanism 24 closely adheres to and protrudes from the ground, and in the lowered state, the liftable barrier mechanism 24 is embedded in the ground.

[0040] In application, this system is designed for the pedestrian entrances (i.e., the installation locations of the doors 3) of newly built or renovated sluices, pumping stations or hydropower station buildings, and mainly enhances the safety and functionality of the entrance by dividing the first sensing area and the second sensing area. The system effectively prevents the intrusion of non-target organisms through physical isolation and automatic control technologies.

[0041] Among them, the purpose of the first sensing area is to sense when a person enters the interior space of the building from outside the building, and it is also the first barrier to prevent organisms other than humans from entering the interior of the building.

[0042] The second sensing area is a further refinement of the barrier. Through area division and function combination, it prevents animals from following when humans enter the building interior, eliminating potential safety hazards.

[0043] In the application, the first sensing area is a sloping land, mainly a buffer sloping land set to connect the outdoor and indoor elevations of the building. The width is adjusted according to the width of the entrance, the slope is fixed at 1:12, and the surface is made of anti-slip material to ensure safety. The pressure sensors are installed in the middle of the sloping land. The sensing area of each pressure sensor is 0.5 square meters, arranged in a grid pattern to form the first pressure sensor array 111 to cover the entire slope surface.

[0044] Among them, the maximum slope ratio of the sloping land does not exceed 1:12 to ensure the safety and comfort of pedestrians (including the disabled). At the same time, it ensures that the indoor water flow direction of the building is outward, further consolidating the indoor safety of the building.

[0045] Among them, pressure sensors are provided at the lower part of the sloping land. When any one of the pressure sensors is activated (i.e., senses a weight exceeding 40 kg), the control system will immediately send a signal to the second sensing area to trigger the relevant procedures in the second sensing area to prevent non-target entry.

[0046] Through the collaborative detection architecture of setting internal and external dual sensing areas in the embodiments of the present application, all-round pressure monitoring of the entrance area is achieved. The first pressure sensor array conducts preliminary identification, and the second pressure sensor array continuously tracks the objects that have entered the entrance. Combining the two-way data integration ability of the signal processing unit, a dynamic response mechanism is formed. This hierarchical detection system can effectively distinguish pressure signals from different sources, avoid the problem of false triggering of a single sensor, and at the same time improve the system judgment accuracy through the joint analysis of pressure signals to ensure the timeliness and accuracy of the lifting control of the blocking mechanism.

[0047] In one embodiment, the second sensing area 2 includes a first control area 21, a second control area 233, and a buffer area 22 for connecting the first control area 21 and the second control area 233;

[0048] Both the first control area 21 and the second control area 233 are provided with liftable blocking mechanisms 24, and the buffer area 22 is provided with a second pressure sensor array 221;

[0049] The signal processing unit 5 is configured to:

[0050] When the first pressure sent by the first pressure sensor array 111 is greater than a predetermined pressure threshold, control the liftable blocking mechanism 24 in the first control area 21 to rise;

[0051] When the second pressure sent by the second pressure sensor array 221 is greater than a predetermined pressure threshold, the liftable barrier mechanism 24 of the first control area 21 is controlled to rise, and the liftable barrier mechanism 24 of the second control area 233 is controlled to fall;

[0052] When the first pressure and the second pressure are both less than a predetermined pressure threshold, the liftable blocking mechanism 24 controlling the first control area 21 and the second control area 233 is raised.

[0053] In application, the signal processing unit 5 is connected to the second sensing area 2. The second sensing area 2 is further divided into three areas: a first control area 21, a buffer area 22, and a second control area 23.

[0054] The first control area 21 is consistent with the second control area 23 in form, structure and principle, and only the position is different. The first control area 21 and the second control area 23 are spaced at least 2 meters apart, serving as a buffer zone for pedestrians. The second control area 23 on the ground is a rectangular area, wherein the rectangular area has an outer sideline and an inner sideline. The inner sideline is used as a boundary, and the outer area is located outside the building, and the inner area is located inside the building.

[0055] The embodiment of the present application constructs a three-level protection response system by subdividing the second sensing area into a control area and a buffer area with logical associations. The first control area is responsible for primary blocking, the second control area implements secondary protection, and the buffer area undertakes the status confirmation function to form a progressive safety line of defense. The signal processing unit implements differentiated control strategies based on the combination of pressure signals in different areas. For example, when the internal pressure is triggered, the combined lifting and lowering actions of the barrier mechanism are synchronously executed. This multimodal response mechanism can not only prevent external intrusion and penetration, but also avoid the risk of internal retention, significantly improving the system's adaptability to complex scenarios.

[0056] In one embodiment, Figure 2 , 5 As shown, the liftable blocking mechanism 24 includes:

[0057] A base assembly 241 pre-buried in the ground 29;

[0058] A column assembly 242 capable of vertically ascending and descending in a base assembly 241;

[0059] A blocking plate 246 used to connect the column assemblies 242 at both ends and to work in conjunction with the column assemblies 242;

[0060] The first control area 21 and the second control area 233 are provided with a partition groove for accommodating the partition plate 246 at a position corresponding to the partition plate 246. The partition plate 246 has a storage state hidden in the partition groove and a working state protruding from the ground surface;

[0061] The column assembly 242 is configured to be controlled by the signal processing unit 5, extend out of the base assembly 241 and put the linked baffle 246 into the working state, or fall back into the base assembly 241 and put the linked baffle 246 into the storage state.

[0062] In the application, the first control area 21 and the second control area 23 are both at the two end base assemblies 241, and the distance between each area base assembly 241 is greater than or equal to 3 meters and less than or equal to 6 meters. If it exceeds 6 meters, a base assembly 241 needs to be arranged in the middle.

[0063] The base assembly 241 is internally provided with a liftable column assembly 242. Among them, the column assembly 242 exposes at least 0.6 meters above the ground finish surface. A baffle 246 is arranged between two column assemblies 242, and the baffle 246 and the column assembly 242 are fixedly engaged with each other.

[0064] Among them, the base assembly 241 is 1.5 times the height of the column assembly 242. The column assemblies 242 in the first control area 21 and the second control area 23 are lifted through the mechanical structure of the underground base assembly 241, and the column assemblies 242 in each area are driven by hydraulic or electromechanical means.

[0065] In the application, a hidden flange 245 is provided at the top of the base assembly 241, and the thickness of the hidden flange is a conventional size. After the construction is completed, the top of the flange is at the same elevation as the ground finish surface to ensure flatness, so as to obtain the safety and comfort of pedestrians.

[0066] A power interface 244 is provided at the upper end of the base assembly 241, which serves as the power supply end of the base assembly 241 to ensure its operation.

[0067] Among them, the power interface 244 adopts a waterproof design, and two power interfaces 244 are provided on each base assembly 241 to ensure that the standby power supply can be quickly switched when any one of the interfaces fails.

[0068] Among them, the height of the baffle 246 is the same as that of the column assembly 242. During the up and down movement of the column assembly 242, the baffle 246 is simultaneously driven to rise and fall, ensuring that there is at least 0.6 meters of blocking space at the entrance and exit to prevent rodents such as mice from entering. Among them, a warning sign 24 painted yellow is provided at the top of the baffle 246 to remind pedestrians that it is in the lifted state and avoid passing to ensure safety.

[0069] The embodiments of the present application achieve the unity of functionality and concealment through the design of a modular barrier mechanism. The embedded installation of the base component ensures the flatness of the ground and avoids affecting normal passage; the vertical lifting mode of the column component has higher space utilization efficiency compared to rotary or translation mechanisms. The cooperative structure design of the barrier plate 246 and the partition groove is completely hidden under the ground surface in the storage state, eliminating visual and behavioral obstacles; in the working state, a continuous barrier surface is formed through mechanical linkage to ensure the reliability of physical protection. This reversible deformation mechanism takes into account the dual needs of daily use and emergency protection.

[0070] In one embodiment, the base component 241 is provided with a first drain port 243 at the bottom that communicates the inside and outside of the installation cavity of the base component 241, and a power interface 244 for connecting the internal drive component and the signal processing unit 5 at the top. The first control area 21 and the second control area 233 are embedded with a drain pipe 28 that communicates with the first drain port 243 of each base component 241 on the ground 29, and one end of the drain pipe 28 extends to the drainage ditch 4.

[0071] In application, the lower end of the base component 241 is provided with a first drain port 243, and the drainage system is designed to be self-cleaning. The drainage slope inside the base component 241 ensures smooth water flow, and the transition interface connected to the external drain pipe 42 uses flexible materials to adapt to the effects of ground settlement and temperature changes.

[0072] During the up and down movement of the column component 242, if water enters the base component 241, it can ensure that the water body flows through the first drain port 243 to the drain pipe 28 and finally reaches the drainage ditch 4 on the floor, avoiding damage to circuit equipment and other places in the base component 241 caused by water accumulation.

[0073] Among them, to ensure the smooth operation of drainage, the base component 241 on the side far from the drainage ditch slopes towards the side close to the drainage ditch to ensure that the drainage ditch 4 has a certain drainage slope and finally runs off to the drainage ditch. Among them, the drainage ditch is connected to the municipal pipeline to ensure the self-drainage of rainwater within the bearing range.

[0074] Among them, as Figure 3 and 4 shown, below the ground 29 of the second induction area 2, there are successively provided a road or paving surface layer 293, a concrete layer 291, and a reinforced concrete cushion layer 292 from the ground surface downwards.

[0075] When encountering extreme external weather and there is too much rainwater entering the base component 241, resulting in the self-drainage of rainwater in the drainage ditch, there is a water pump 43 installed inside, which is used together with a float valve. When the water level reaches a certain value, the float ball rises and the water pump automatically starts working. When the water level is lower than a certain value, the float ball drops and the water pump stops working.

[0076] The embodiments of the present application solve the waterproof problem of underground installation equipment through an integrated drainage system design. The drainage outlet at the bottom of the base forms a hierarchical diversion channel with the pre-buried drainage pipe, effectively preventing equipment corrosion and electrical safety risks caused by water accumulation inside the base assembly. The sealing design of the top power interface, combined with the drainage system, constructs a dual protection system to ensure the stable operation of electronic components in a humid environment. This feature extends the service life of key components and reduces the maintenance frequency at the same time, being particularly suitable for the high-humidity working conditions of hydraulic buildings.

[0077] In one embodiment, a biological repelling device 26 is provided in the second sensing area 2, and the output end of the signal processing unit 5 is connected to the input end of the biological repelling device 26;

[0078] The signal processing unit 5 is configured to control the biological repelling device 26 to be turned on when the first pressure sent by the first pressure sensor array 111 is greater than a predetermined pressure threshold.

[0079] The embodiments of the present application achieve collaborative protection of physical barrier and active defense through the introduction of a biological repelling device. Through intelligent linkage with the pressure detection system, the repelling program is started at the first time of identifying potential biological intrusion, forming a complete protection chain of "detection - barrier - expulsion". This composite protection strategy breaks through the limitations of traditional single-barrier modes, can prevent small organisms from infiltrating, and significantly improves the multi-dimensional protection ability of the system.

[0080] In one embodiment, a connecting wall 25 is provided in the second sensing area 2, which is separated on both sides and penetrates through the first control area 21 and the second control area 233, and the biological repelling device 26 is arranged on the connecting wall 25.

[0081] In application, two connecting walls 25 are provided perpendicular to the entrance in the second sensing area to prevent non-targets from entering. Among them, the connecting wall 25 is tightly connected to the column assembly 242 of the first control area and the second control area when rising. A biological repelling device 26, such as a rat repeller, is provided between the two connecting walls 25, which can emit ultrasonic waves with a frequency of 18000 Hz to 24000 Hz when started. A second drainage port 251 is provided at the bottom of the connecting wall 25 for discharging indoor accumulated water.

[0082] The embodiments of the present application adopt a structural design of a through-type connecting wall, enabling the repelling device to radiate to the edge areas on both sides, forming a three-dimensional protection network. This layout method avoids the structural complexity brought by installing brackets separately, and at the same time utilizes the building body structure to enhance the stability of the device, ensuring the effective coverage range of repelling means such as sound waves / ultrasonic waves.

[0083] In one embodiment, a protective ceiling 7 is further included, and the protective ceiling 7 is arranged at the entrance and covers the first sensing area 1 and the second sensing area 2.

[0084] In the application, there are canopies with the same width at the top of the outdoor area of the building, the first sensing area, and the second sensing area, which protect the interior of the building from the adverse weather outside, and at the same time provide a relatively safe external environment for people. It also prevents impurities such as rain, snow, or fallen leaves from entering the interior space of the building.

[0085] The canopy is made of transparent polycarbonate material with high structural strength and can resist the influence of wind speed of level 8. The canopy covers the entire first sensing area and the second sensing area, effectively isolating external impurities such as rain, snow, and fallen leaves.

[0086] The canopy is fixed by stainless steel brackets, and a fulcrum is set every 1 meter to ensure its stability and long-term durability. A simple cleaning and maintenance passage is designed for easy daily cleaning and emergency maintenance.

[0087] The embodiment of the present application adopts an integral protective canopy to construct an all-weather protection system. The shielding protection of the canopy for the sensing equipment can reduce the influence of environmental factors such as sunlight exposure and rain erosion on the detection accuracy; the covering protection of the mechanical components reduces the risk of mechanism jamming caused by sand accumulation. The extended coverage design forms a physical isolation belt, which can still maintain the normal operation of the system under bad weather conditions and ensure the continuous effectiveness of the protection function.

[0088] In one embodiment, warning signs 27 are provided on the first control area 21, the second control area 233, and the partition board 246.

[0089] Among them, warning signs 27 are painted in yellow within the outlines of the first control area 21 and the second control area 23 (i.e., the corresponding ground positions) to form a warning area. The main purpose is to remind people that functional lifting will be carried out in this area to prevent safety accidents when people pass through the area. Ensure that users can clearly understand the lifting state and possible safety tips.

[0090] The embodiment of the present application sets up multi-level warning signs. Among them, the control area signs provide operation guidance to prevent misoperation from triggering system malfunctions; the signs on the partition board 246 form a visual warning line to improve the recognition of dangerous areas by personnel. Convert passive protection into active warning, and effectively reduce safety accidents caused by human factors through warning information that can be recognized by the human eye, while meeting the human factors engineering requirements of building safety codes.

[0091] The embodiment of the present application also provides a protection method for the entrance of a hydraulic structure, which is used for a protection system for the entrance of a hydraulic structure. The method includes:

[0092] Identifying a trigger signal through pressure sensing data;

[0093] Responding to the trigger signal to control the lifting state conversion of the liftable barrier mechanism.

[0094] In the application, the working principle of the protection method of this system is as follows:

[0095] When a person approaches the building entrance, they first enter the first sensing area. In this area, there are pressure sensors installed at the bottom, which are used to detect the weight of the target object above. If the detected weight exceeds 40 kilograms, the system determines it as a normal adult and activates the control system. This ensures that the system will not malfunction due to small animals or irrelevant objects.

[0096] After receiving the signal from the pressure sensor, the control system (i.e., the signal processing unit 5) will send an instruction to the base component 241 in the second sensing area (the first control area 21). This base component 241 controls the lifting and lowering of the column component 242 to ensure that the barrier plate 246 is flush with the ground for the person to pass through. At the same time, the control system also controls the rat repeller in the second sensing area to start, emitting ultrasonic waves from 18,000 Hz to 24,000 Hz to drive away small animals or insects that may follow the person and prevent them from entering the building interior.

[0097] When the person passes through the first control area 21, they will enter the buffer area 22 in the second sensing area. There are also pressure sensors installed in the lower part of this area to detect and confirm that the person has passed through the preliminary safety area.

[0098] After receiving the passing signal, the control system will immediately raise the barrier plate 246 in the first control area 21 to prevent the entry of subsequent non-target objects or people, and at the same time lower the barrier plate 246 in the second control area 23 to prepare for the person to further enter the interior.

[0099] After the person completely enters the building interior, the pressure sensor in the buffer area 22 in the second sensing area detects a change again and sends a closing signal to the control system.

[0100] Based on this instruction, the control system raises the barrier plate 246 in the second control area 23 to ensure the closure and safety of the area, and at the same time ends the entire process.

[0101] To deal with emergencies, there is a manual switch 6 beside the controller. This switch facilitates the staff to manually adjust the column component 242 and other mechanisms in each sensing area according to actual needs, thereby increasing the flexibility of the system and its ability to handle various situations.

[0102] Through the design of the automatic column component 242 and the barrier plate 246, this system avoids the possible passage obstacles caused by fixed rat-proof plates. Especially for disabled people and those carrying large equipment, it provides an unobstructed passage experience. In case of emergencies such as fires or events that require rapid evacuation, the automatic lifting mechanism can quickly lower to clear the passage obstacles, reducing the escape time and improving the efficiency of emergency response.

[0103] Through a flexible lifting mechanism and high-frequency ultrasonic technology, the system can effectively prevent the intrusion of rodents of various sizes and flexibilities, including mice, and has better adaptability and blocking effect compared with fixed rat guards. The design of the baffle and column components of the system can adjust the height and position according to the actual situation to ensure effective prevention of all potential intruders.

[0104] Compared with traditional rat guards, the system uses column components and baffles made of high-strength and weather-resistant materials, reducing the loss caused by external environmental factors (such as rain, snow, and ultraviolet radiation) and extending the service life. The system design is easy to clean and maintain, especially the self-cleaning drainage system, which ensures the long-term integrity of the structure and the continuous effectiveness of the function.

[0105] The system fully considers the coordination with the building and aesthetic requirements, and is especially suitable for historical buildings or places that need to maintain a specific appearance. The integrated design of the automatic lifting mechanism and the baffle avoids the visual disharmony problems that may be caused by traditional rat guards, and at the same time provides more possibilities for customization to adapt to different building styles and entrance designs.
