Description

Technical Field

[0001] This application relates to the field of water conservancy engineering construction technology, specifically to an inlet protection system for a hydraulic structure and a hydraulic structure. Background Technology

[0002] The primary function of existing rodent barriers in hydraulic engineering structures is to prevent rats and other small pests from entering the buildings, especially in remote locations such as sluice gates, pumping stations, and power stations. These locations, due to their remoteness and different environments compared to cities, have a high concentration of human activity indoors, creating food residue that attracts rodents. These rodents may then enter large electrical or mechanical equipment such as high and low voltage switchgear and pump rooms, causing damage. Therefore, installing rodent barriers at the entrances of these structures aims to create a physical barrier to prevent rats from passing through, while minimizing the impact on pedestrian traffic.

[0003] Rat barriers are typically made of durable materials such as stainless steel, aluminum, or special hard plastics. These materials are chosen because they resist the biting and scratching of rats, preventing them from passing through. In terms of design, the thickness and height of rat barriers need to meet certain requirements to prevent small animals from squeezing into gaps under or on the sides of doors, while minimizing obstruction to human passage. However, fixed rat barriers can easily lead to the following problems:

[0004] Rodent barriers impede operation and personnel passage. Fixed rodent barriers, often located at the bottom of doors, frequently constitute a height obstacle, particularly inconvenient for water conservancy workers using wheelchairs or carrying trolleys. This is especially true when inspecting or moving equipment or parts, requiring the temporary removal of existing barriers, which are often forgotten to be reinstalled, creating safety hazards. In high-traffic areas during rush hour, the frequent opening and closing of rodent barriers significantly increases passage time and labor intensity, especially during peak hours, potentially leading to congestion and dissatisfaction.

[0005] In emergencies, such as fires or other events requiring rapid evacuation, fixed rodent barriers can obstruct escape routes and increase escape time. If poorly designed, sharp edges or protruding parts of the rodent barrier can cause cuts or tripping injuries to those passing through.

[0006] Limited adaptability. Fixed rodent barriers may not be able to completely stop all mice in certain situations, especially for mice of different sizes and agility, where their effectiveness may be limited.

[0007] Rat barriers are difficult to maintain and have poor durability. They require regular inspection and maintenance to ensure structural integrity and proper function. In outdoor environments, rat barriers can degrade rapidly due to weather conditions such as rain, snow, and UV exposure. Frequent physical contact (such as kicking or pushing) can cause deformation or damage to the rat barrier, requiring not only repair or replacement but also potential loss of rat-repellent function during the damage period.

[0008] Poor aesthetics and design adaptability. Rat barriers may be made of metal or other industrial materials, which often clash with the building's aesthetic design, especially in historic buildings or locations where a certain appearance needs to be maintained. The size and shape of rat barriers may not fit all types of doors or entrances, particularly non-standard sizes or specially designed doors, requiring custom solutions, which can increase costs and implementation difficulties.

[0009] Therefore, in water conservancy engineering construction, how to prevent rats from entering and damage related electrical equipment 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 present application provides an entrance protection system for hydraulic structures and a hydraulic structure to solve the problem that existing hydraulic engineering structures cannot prevent rats from entering and prevent damage to related electrical equipment while ensuring the smooth passage of pedestrians.

[0011] The first aspect of this application provides a hydraulic structure inlet protection system, comprising:

[0012] The first sensing area is located outside the entrance and includes a first pressure sensor array;

[0013] The second sensing area is located between the entrance and the first sensing area and is connected to the first sensing area. It includes a liftable barrier mechanism and a second pressure sensor array.

[0014] The signal processing unit has 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 second aspect of this application provides a hydraulic structure with an entrance protection system for a hydraulic structure as provided in the first aspect of this application at its entrance.

[0016] The hydraulic structure entrance protection system provided in the first aspect of this application includes a first sensing zone located outside the entrance, comprising a first pressure sensor array; and a second sensing zone located inside the entrance and connected to the first sensing zone, comprising a liftable barrier mechanism and a second pressure sensor array; and a signal processing unit whose input end is connected to the output ends of the first and second pressure sensor arrays, and whose output end is communicatively connected to the input end of the liftable barrier mechanism. By setting up a collaborative detection architecture with internal and external dual sensing zones, comprehensive pressure monitoring of the entrance area is achieved. The first pressure sensor array performs initial identification, while the second pressure sensor array continuously tracks objects that have entered the entrance. Combined with the bidirectional data integration capability of the signal processing unit, a dynamic response mechanism is formed. This hierarchical detection system can effectively distinguish pressure signals from different sources, avoiding the problem of false triggering by a single sensor. Simultaneously, the joint analysis of pressure signals improves the system's judgment accuracy, ensuring the timeliness and accuracy of the barrier mechanism's lifting control.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0029] like Figure 1 As shown, this application embodiment provides a hydraulic structure inlet protection system, including:

[0030] The first sensing area 1 is located outside the inlet and includes a first pressure sensor array 111;

[0031] The second sensing area 2 is located between the entrance and the first sensing area 1 and is connected to the first sensing area 1. It includes a liftable barrier mechanism 24 and a second pressure sensor array 221.

[0032] The signal processing unit 5 has its input end connected to the output end of the first pressure sensor array 111 and the second pressure sensor array 221, and its output end is communicatively connected to the input end of the liftable barrier mechanism 24.

[0033] The signal processing unit 5 is configured to control the lifting and lowering of the lifting barrier mechanism 24 based on the pressure signals of the first pressure sensor array 111 and / or the second pressure sensor array 221.

[0034] In application, this system is designed for pedestrian entrances and exits (i.e., the installation location of door 3) of newly built or renovated sluice gates, pumping stations, or hydropower stations. It primarily enhances the security and functionality of the entrance by dividing it into a first sensing zone and a second sensing zone. Through physical isolation and automatic control technology, the system effectively prevents the intrusion of non-target organisms.

[0035] The purpose of the first sensing zone is to ensure that people can sense when entering the interior space of a building from the outside, and it is also the first barrier to prevent creatures other than humans from entering the interior of the building.

[0036] The second sensing zone is a further refinement of the barrier. Through the division of areas and the combination of functions, it prevents animals from following humans into the building, thus eliminating potential safety hazards.

[0037] In this application, the first sensing area is a slope, primarily designed as a buffer zone connecting the outdoor and indoor elevations of the building. Its width is adjusted according to the entrance / exit width, while the slope is fixed at 1:12. The surface is made of anti-slip material to ensure safety. Pressure sensors are installed in the middle of the slope, each with a sensing area of ​​0.5 square meters, arranged in a grid pattern to form the first pressure sensor array 111, covering the entire slope.

[0038] The maximum slope ratio is 1:12 to ensure pedestrian safety and comfort. Simultaneously, the direction of water flow inside the building is ensured to be outwards, further enhancing the building's interior safety.

[0039] Pressure sensors are installed at the bottom of the slope. When any pressure sensor is activated (i.e., it senses a weight of more than 40 kilograms), the control system will immediately send a signal to the second sensing area to trigger the relevant program in the second sensing area and prevent non-targets from entering.

[0040] This application embodiment achieves comprehensive pressure monitoring of the entrance area by setting up a collaborative detection architecture with internal and external dual sensing zones. A first pressure sensor array performs initial identification, while a second pressure sensor array continuously tracks objects that have entered the entrance. Combined with the bidirectional data integration capability of the signal processing unit, a dynamic response mechanism is formed. This hierarchical detection system can effectively distinguish pressure signals from different sources, avoiding the problem of false triggering by a single sensor. Simultaneously, the joint analysis of pressure signals improves the system's judgment accuracy, ensuring the timeliness and accuracy of the barrier mechanism's lifting control.

[0041] In one embodiment, the second sensing area 2 includes a first control area 21, a second control area 233, and a buffer zone 22 for connecting the first control area 21 and the second control area 233;

[0042] Both the first control zone 21 and the second control zone 233 are equipped with a liftable barrier mechanism 24, and the buffer zone 22 is equipped with a second pressure sensor array 221.

[0043] Signal processing unit 5 is configured as follows:

[0044] When the first pressure sent by the first pressure sensor array 111 is greater than a predetermined pressure threshold, the liftable barrier mechanism 24 of the first control area 21 is raised.

[0045] When the second pressure sent by the second pressure sensor array 221 is greater than the predetermined pressure threshold, the lifting barrier mechanism 24 of the first control area 21 is raised and the lifting barrier mechanism 24 of the second control area 233 is lowered.

[0046] When both the first pressure and the second pressure are less than the predetermined pressure threshold, the liftable barrier mechanism 24 of the first control zone 21 and the second control zone 233 is raised.

[0047] In the application, the signal processing unit 5 is connected to the second sensing area. The second sensing area 2 is further subdivided into three regions: the first control area 21, the buffer zone 22, and the second control area 23.

[0048] The first control zone 21 is identical in form, structure, and principle to the second control zone 23, differing only in location. The distance between the first control zone 21 and the second control zone 23 is at least 2 meters, serving as a buffer zone for pedestrians. The second control zone 23 is a rectangular area on the ground, with an outer edge and an inner edge. The inner edge serves as a boundary, with the outer area located outdoors and the inner area located indoors.

[0049] This application embodiment constructs a three-tiered protection and response system by refining the second sensing area into a logically related control area and a buffer zone. The first control area is responsible for primary isolation, the second control area implements secondary protection, and the buffer zone undertakes the status confirmation function, forming a progressive security defense line. The signal processing unit implements differentiated control strategies based on the pressure signal combinations of different areas. For example, when internal pressure is triggered, it synchronously executes the lifting and lowering combination of the isolation mechanism. This multimodal response mechanism can prevent external intrusion and avoid the risk of internal retention, significantly improving the system's adaptability to complex scenarios.

[0050] In one embodiment, such as Figure 2 , 5 As shown, the liftable barrier mechanism 24 includes:

[0051] Base assembly 241 pre-embedded in the ground 29;

[0052] A column assembly 242 that can be vertically raised and lowered within a base assembly 241;

[0053] A baffle plate 246 is used to connect the two end column assemblies 242 and to be linked with the column assemblies 242;

[0054] The first control area 21 and the second control area 233 are provided with partition grooves for storing the partition plate 246 at positions 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.

[0055] The column assembly 242 is configured to be controlled by the signal processing unit 5, extending out of the base assembly 241 and putting the linked barrier plate 246 into operation, or falling back into the base assembly 241 and putting the linked barrier plate 246 into storage.

[0056] In the application, the first control area 21 and the second control area 23 are both located at two end base components 241. The distance between the base components 241 in each area is greater than or equal to 3 meters and less than or equal to 6 meters. If the distance exceeds 6 meters, a base component 241 needs to be installed in the middle.

[0057] The base assembly 241 contains a liftable column assembly 242, wherein the column assembly 242 protrudes at least 0.6 meters above the finished ground surface. A partition plate 246 is provided between two column assemblies 242, and the partition plate 246 is interlocked and fixed to the column assembly 242.

[0058] The base assembly 241 is 1.5 times the height of the column assembly 242. The column assemblies 242 of the first control zone 21 and the second control zone 23 are raised and lowered through the mechanical structure of the underground base assembly 241, and the column assemblies 242 in each zone are driven by hydraulic or electromechanical means.

[0059] In application, a concealed flange 245 is provided at the top of the base assembly 241. The thickness of the concealed flange is of standard size, ensuring that after construction is completed, the top of the flange is at the same elevation as the finished ground surface, ensuring flushness and thus achieving pedestrian safety and comfort.

[0060] A power interface 244 is provided on the upper end of the base assembly 241 as the power supply terminal for the base assembly 241 to ensure its operation.

[0061] The power interface 244 is waterproof, and each base assembly 241 has two power interfaces 244 to ensure that it can quickly switch to backup power in the event of a failure of any interface.

[0062] The barrier panel 246 is at the same height as the column assembly 242. As the column assembly 242 moves up and down, it simultaneously raises and lowers the barrier panel 246, ensuring a minimum 0.6-meter barrier space at the entrance / exit to prevent rodents such as rats from entering. A yellow warning sign 24 is located at the top of the barrier panel 246 to indicate that it is currently raised and to prevent passage, ensuring safety.

[0063] This application's embodiment achieves a balance between functionality and concealment through a modular barrier mechanism design. The pre-embedded installation of the base assembly ensures ground flatness, avoiding obstruction of normal passage; the vertical lifting mode of the column assembly offers higher space utilization efficiency compared to rotation or translation mechanisms. The cooperative structural design of the barrier plate 246 and the barrier groove completely conceals it beneath the ground surface in the retracted state, eliminating visual and behavioral obstacles; in the working state, it forms a continuous barrier surface through mechanical linkage, ensuring the reliability of physical protection. This reversible deformation mechanism caters to both daily use and emergency protection needs.

[0064] In one embodiment, the base assembly 241 has a first drain outlet 243 at the bottom that connects the inside and outside of the mounting cavity of the base assembly 241, and a power interface 244 at the top for connecting the internal drive assembly and the signal processing unit 5. The first control area 21 and the second control area 233 have a drain pipe 28 pre-embedded in the ground 29 that communicates with the first drain outlet 243 of each base assembly 241, and one end of the drain pipe 28 extends to the drainage ditch 4.

[0065] In application, the base assembly 241 is provided with a first drain outlet 243 at the lower end. The drainage system is designed to be self-cleaning. The drainage slope inside the base assembly 241 ensures that the water flows smoothly and without obstruction. The transition interface connected to the external drain pipe 42 is made of flexible material to adapt to the effects of ground settlement and temperature changes.

[0066] During the up-and-down movement of the column assembly 242, if water enters the base assembly 241, the water can be ensured to flow through the first drain outlet 243 to the drain pipe 28 and finally reach the drainage ditch 4 of the floor, thus preventing water accumulation from damaging the circuit equipment and other parts of the base assembly 241.

[0067] To ensure smooth drainage operation, the base component 241, located away from the drainage ditch, is sloped towards the drainage ditch, ensuring a certain drainage slope for the drainage ditch 4, ultimately leading to the drainage ditch. The drainage ditch is connected to municipal pipelines, ensuring rainwater drainage within its capacity.

[0068] Among them, such as Figure 3 and 4 As shown, below the ground 29 of the second sensing zone 2, from the ground surface downwards, there are a road or paved surface layer 293, a concrete layer 291 and a reinforced concrete cushion layer 292.

[0069] When encountering extreme external weather, if too much rainwater enters the base component 241, causing the rainwater in the drainage ditch to drain, a water pump 43 is installed inside, which works together with a float valve. When the water level reaches a certain value, the float rises and the water pump starts working automatically. When the water level falls below a certain value, the float falls and the water pump stops working.

[0070] This application's embodiment solves the waterproofing problem of underground installed equipment through an integrated drainage system design. The drainage outlet at the bottom of the base and the pre-embedded drainage pipe form a tiered drainage channel, effectively preventing equipment corrosion and electrical safety risks caused by water accumulation inside the base components. The sealed design of the top power interface, combined with the drainage system, constructs a dual protection system, ensuring the stable operation of electronic components in humid environments. This feature extends the service life of critical components while reducing maintenance frequency, making it particularly suitable for the high-humidity operating environments of hydraulic structures.

[0071] In one embodiment, the second sensing area 2 is provided with a biological de-escaping device 26, and the output terminal of the signal processing unit 5 is connected to the input terminal of the biological de-escaping device 26.

[0072] The signal processing unit 5 is configured to control the biological decoupling device 26 to open when the first pressure sent by the first pressure sensor array 111 is greater than a predetermined pressure threshold.

[0073] This application's embodiments achieve synergistic protection through the introduction of a biological repellency device, combining physical barriers with active defense. Through intelligent linkage with a pressure detection system, the repellency procedure is initiated the moment a potential biological intrusion is identified, forming a complete "detection-barrier-repellency" protection chain. This composite protection strategy overcomes the limitations of traditional single-barrier modes, preventing the infiltration of small organisms and significantly enhancing the system's multi-dimensional protection capabilities.

[0074] In one embodiment, the second sensing area 2 is provided with connecting walls 25 that are separated on both sides and pass through the first control area 21 and the second control area 233, and the biological decoy device 26 is disposed on the connecting wall 25.

[0075] In the application, the second sensing area is equipped with two connecting walls 25 perpendicular to the entrance to prevent unauthorized entry. These connecting walls 25 are tightly connected to the column assemblies 242 of the first and second control areas when raised. A biological repelling device 26, such as a rodent repellent, is located between the two connecting walls 25; when activated, it emits ultrasonic waves at a frequency of 18000Hz to 24000Hz. A second drain outlet 251 is located at the bottom of each connecting wall 25 for draining accumulated indoor water.

[0076] This application's embodiment employs a through-wall connection structure, allowing the repelling device to cover both edge areas, forming a three-dimensional protective network. This layout avoids the structural complexity of separate installation brackets, while utilizing the building's structure to enhance the device's stability and ensure the effective coverage of repelling methods such as sound waves / ultrasound.

[0077] In one embodiment, a protective canopy 7 is also included, which is disposed at the entrance and covers the first sensing area 1 and the second sensing area 2.

[0078] In this application, the building's exterior, the top of the first sensing zone, and the second sensing zone are equipped with canopies of equal width. This protects the building's interior from severe weather conditions and provides a relatively safe external environment for people. It also prevents rain, snow, fallen leaves, and other debris from entering the building's interior space.

[0079] The canopy is made of transparent polycarbonate material, with high structural strength, capable of withstanding winds up to level 8. The canopy covers the entire first and second sensing zones, effectively isolating rain, snow, fallen leaves, and other external debris.

[0080] The canopy is secured with a stainless steel frame, with a support point every 1 meter to ensure its stability and long-term durability. A simple cleaning and maintenance access is designed for easy routine cleaning and emergency maintenance.

[0081] This application embodiment employs an integrated protective canopy to construct an all-weather protection system. The canopy's shielding and protection of the sensing equipment reduces the impact of environmental factors such as sunlight exposure and rain erosion on detection accuracy; its coverage and protection of mechanical components reduces the risk of mechanical jamming caused by dust accumulation. The extended coverage design forms a physical isolation zone, ensuring the system can maintain normal operation even under severe weather conditions and guaranteeing the continued effectiveness of the protective function.

[0082] In one embodiment, warning signs 27 are provided on the first control area 21, the second control area 233, and the barrier plate 246.

[0083] Within the outlines of the first control area 21 and the second control area 23 (i.e., the ground at the corresponding locations), yellow warning signs 27 are painted to form warning zones. Their main purpose is to remind people that these areas will undergo functional elevation changes, preventing safety accidents when people pass through them. This ensures that users are clearly aware of the elevation status and potential safety warnings.

[0084] This application embodiment sets up multi-layered warning signs. Among them, the control area sign provides operation guidance to prevent accidental touches that could cause system malfunctions; the barrier plate 246 sign forms a visual warning line, improving personnel's ability to identify dangerous areas. This transforms passive protection into active early warning, effectively reducing safety accidents caused by human factors through eye-readable warning information, while also meeting the human factors engineering requirements of building safety codes.

[0085] In application, the working principle of the protection method of this system is as follows:

[0086] When a person approaches the building entrance, they first enter the first sensing zone. In this zone, pressure sensors at the bottom detect the weight of any object above. If the detected weight exceeds 40 kilograms, the system identifies the person as a normal adult and activates the control system. This ensures the system will not malfunction due to small animals or unrelated objects.

[0087] After receiving the signal from the pressure sensor, the control system (i.e., signal processing unit 5) sends a command to the base assembly 241 in the second sensing area (first control area 21). This base assembly 241 controls the raising and lowering of the column assembly 242 to ensure that the barrier plate 246 is flush with the ground, facilitating personnel passage. Simultaneously, the control system also activates the rodent repellent in the second sensing area, emitting ultrasonic waves of 18000Hz to 24000Hz to repel small animals or insects that may accompany personnel, preventing them from entering the building.

[0088] After personnel pass through the first control zone 21, they will enter the buffer zone 22 within the second sensing zone. Pressure sensors are also installed at the bottom of this zone to detect and confirm that personnel have passed through the initial security zone.

[0089] Upon receiving the pass signal, the control system will immediately raise the barrier 246 of the first control zone 21 to prevent subsequent entry of non-target objects or personnel, and at the same time lower the barrier 246 of the second control zone 23 to prepare for personnel to further enter the interior.

[0090] After personnel have fully entered the building, the pressure sensor in buffer zone 22 of the second sensing zone detects the change again and sends a shutdown signal to the control system.

[0091] Based on this instruction, the control system raises the barrier 246 of the second control zone 23 to ensure the enclosure and safety of the area, and at the same time ends the entire process.

[0092] To handle emergencies, a manual switch 6 is provided next to the controller. This switch allows staff to manually adjust the column components 242 and other mechanisms in each sensing area as needed, thereby increasing the system's flexibility and ability to respond to changing situations.

[0093] This system, through the design of the automatic column assembly 242 and the barrier plate 246, avoids the passage obstruction that fixed rodent barriers may cause, providing an unobstructed passage experience, especially for personnel carrying large equipment. In emergencies, such as fires or events requiring rapid evacuation, the automatic lifting mechanism can quickly descend, clearing the passage obstruction, reducing escape time, and improving the efficiency of emergency response.

[0094] The system, utilizing a flexible lifting mechanism and high-frequency ultrasonic technology, effectively prevents the intrusion of rodents of various sizes and agility, including rats, offering better adaptability and blocking effect compared to fixed rodent barriers. The system's barrier and column components are designed to be adjustable in height and position according to actual conditions, ensuring effective deterrence against all potential intruders.

[0095] Compared to traditional rodent barriers, this system uses column components and barrier panels made of high-strength, weather-resistant materials, reducing damage caused by external environmental factors (such as rain, snow, and ultraviolet radiation) and extending its service life. The system is designed for easy cleaning and maintenance, especially the self-cleaning drainage system, ensuring the long-term integrity of the structure and the continued effectiveness of its functions.

[0096] This system takes into full consideration the harmony and aesthetic requirements of the architecture, making it particularly suitable for historical buildings or sites that need to maintain a specific appearance. The integrated design of the automatic lifting mechanism and barrier panels avoids the visual disharmony problems that may be caused by traditional rodent barriers, while providing more customization possibilities to adapt to different architectural styles and entrance designs.

[0097] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
