[0002] In the field of water conservancy projects, existing mechatronic gates, a type of gate device that combines mechanical transmission with electrical control, are primarily used to control water flow. They can intercept floodwaters and prevent them from spreading during flood control; provide on-demand water to farmland during irrigation; regulate water levels and ensure channel depth during navigation; and control water flow to meet power generation needs in hydropower generation. Furthermore, existing mechatronic gates offer a high degree of automation, enabling remote operation and monitoring. This improves the management efficiency and safety of water conservancy projects and effectively ensures the rational allocation and utilization of water resources.

[0003] However, existing mechatronic gates generate significant friction between the gate body and the door during opening. This, on the one hand, places a significant load on the drive system, significantly reducing equipment efficiency; on the other hand, the continuous friction causes rapid wear of sealing components, resulting in a decrease in sealing performance and, in turn, serious water leakage.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings). In the description of the present invention, it should be understood that terms such as "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate positions or relationships based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the device or component being referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0042] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0043] The embodiment of the present invention provides a mechatronic gate sealing structure, such as Figures 1-9 As shown, it includes:

[0044] The gate body 100 and the door body 200 , wherein the door body 200 is located inside the gate body 100 and can be raised and lowered.

[0045] The door body 200 has a closed state and an open state. When the door body 200 is in the closed state, the door body 200 and the gate body 100 are tightly fitted together to form an effective barrier. When the door body 200 is in the open state, a channel for water to flow through is formed between the door body 200 and the gate body 100.

[0046] When the door body 200 is opened, the area of ​​the channel increases, and water flows through the channel under the action of driving forces such as upstream and downstream water level difference and pressure difference.

[0047] When the door 200 is closed, the structural integrity of the door 200 and its excellent sealing with the gate body 100 can limit the flow of water to the greatest extent possible. At this time, the water flow is blocked on one side by the door 200 and cannot flow freely from the position of the door 200 to the other side, thereby achieving water flow cutoff control, which can be used in various functional scenarios such as water storage, flood prevention, and separation of different water areas.

[0048] When door 200 is open, the amount of water flowing through it is related to factors such as the degree of door 200 opening and the upstream and downstream water level difference. Generally speaking, the greater the degree of door 200 opening, the greater the water flow. This method of regulating water flow by controlling the degree of door 200 opening can accurately meet the needs of water distribution, flood discharge, irrigation, and other engineering scenarios.

[0049] The driving device serves as the power source of the electromechanical integrated gate sealing structure, and provides power for the movement of other components, including but not limited to the relative movement of the gate body 100 and the door body 200.

[0050] It is understood that the drive device can be a common drive form, such as an electric motor, an internal combustion engine, etc. The power source in the drive device can be centralized, transmitting power to other components through a transmission structure; or the power source can be decentralized, with multiple decentralized power sources driving each component separately.

[0051] In existing water conservancy project gate technology, significant friction exists between the sealing strip of the gate body 100 and the sealing surface of the door body 200 during the gate opening process, and the sealing strip of the gate body 100 and the sealing surface of the door body 200 frequently slide relative to each other. This not only increases the power required to open the gate, resulting in greater opening resistance, but also accelerates the wear of the sealing components, shortening the service life of the seal, thereby affecting the sealing performance of the gate and potentially causing water leakage and other problems.

[0052] Based on this, the electromechanical integrated gate sealing structure provided in the embodiment of the present invention includes multiple sets of sealing devices 300, and the sealing devices 300 include a first sealing belt 311 and a second sealing belt 312, so that the first sealing belt 311 and the second sealing belt 312 move synchronously to reduce friction and wear.

[0053] Specifically, the first sealing strip 311 is located on the gate body 100, and the second sealing strip 312 is located on the door body 200. The gate body 100 and the door body 200 are tightly fitted together by the first sealing strip 311 and the second sealing strip 312. The first sealing strip 311 and the second sealing strip 312 are provided with mutually cooperating meshing structures, which enable the mating surfaces of the first sealing strip 311 and the second sealing strip 312 to tightly fit together, achieving an effective sealing effect.

[0054] When the door 200 is closed, the drive mechanism rotates the first sealing belt 311, causing the first and second sealing belts 311, 312 to move synchronously toward the closed position of the door 200. When the door 200 and the gate body 100 reach a predetermined position, the meshing portions of the first and second sealing belts 311, 312 engage with each other, forming a sealed structure. At this point, the first sealing belt 311 continues to rotate, driving the second sealing belt 312 toward the closed position of the door 200.

[0055] When the door body 200 performs the opening operation, the driving device drives the first sealing belt 311 to rotate in the reverse direction, so that the first sealing belt 311 drives the second sealing belt 312 to move in the reverse direction synchronously. When the door body 200 and the gate body 100 move to the predetermined position, the mating surfaces of the first sealing belt 311 and the second sealing belt 312 separate and disengage, thereby releasing the sealing state of the door body 200 and the gate body 100.

[0056] Therefore, by setting the first sealing belt 311 and the second sealing belt 312 that can move synchronously, the first sealing belt 311 of the gate body 100 and the second sealing belt 312 of the door body 200 can move synchronously when the door body 200 is opened and closed, thereby eliminating the relative sliding and friction between the first sealing belt 311 and the second sealing belt 312.

[0057] Furthermore, to prevent the sealing device 300 from being unable to resist the impact of the water flow due to its limited structural strength, the first sealing strip 311 and the second sealing strip 312 may be deformed under the water flow pressure, thereby generating gaps and causing a decrease in the sealing effect.

[0058] A support structure is provided inside the first sealing strip 311 and the second sealing strip 312, and the support structure can evenly provide support force for the first sealing strip 311 and the second sealing strip 312. The support structure can be a high-strength metal strip or a plastic support rib with a specific structure.

[0059] When water impacts the first and second sealing strips 311, 312, the support structure, with its inherent strength, effectively prevents excessive deformation of the first and second sealing strips 311, 312. The support structure disperses the impact force of the water flow, ensuring more uniform pressure across the first and second sealing strips 311, 312, and preventing gaps from forming due to excessive local pressure.

[0060] Therefore, when the door body 200 is in a closed state, the first sealing strip 311 and the second sealing strip 312 can be further tightly fitted, thereby significantly improving the sealing effect of the sealing device 300 and ensuring the effective blocking and control of water flow by the gate in the water conservancy project.

[0061] It is understood that the door body 200 is fixedly connected to the main screw, which converts the rotational motion of the drive unit into linear motion of the door body 200. During the opening and closing process of the door body 200, the main screw bears the weight of the door body 200 and various forces it is subjected to. In traditional mechatronic gate sealing structures, the main screw must overcome the weight of the door body 200 itself and the friction between the door body 200 and the gate body 100 to achieve the opening action.

[0062] In this embodiment of the present invention, the first sealing strip 311 and the second sealing strip 312 utilize an engaging structure to coordinate and move synchronously. When the door body 200 is subjected to an upward lifting force, the drive device rotates the first sealing strip 311. Under the action of the engaging structure, the second sealing strip 312 is subjected to the vertical upward meshing force of the first sealing strip 311, thereby providing a portion of the upward lifting force for the door body 200, thereby sharing part of the force required by the main screw to lift the door body 200.

[0063] At the same time, when the door body 200 is opened, the first sealing strip 311 and the second sealing strip 312 move synchronously, reducing the friction between the door body 200 and the gate body 100. When the vertical upward force exerted by the first sealing strip 311 on the second sealing strip 312 reduces the positive pressure of the door body 200 on the gate body 100, the friction is also reduced accordingly, thereby reducing the force on the main screw during the gate opening process.

[0064] As a result, the force on the main screw during the gate opening process is effectively reduced, and the gate opening resistance is reduced.

[0065] In one embodiment, Figure 4-Figure 9 As shown, different parts of the sealing device 300 face different working environments and have different loss forms.

[0066] Long-term immersion of the underwater portion of the sealing device 300 in water can cause the material of the sealing device 300 to swell, resulting in dimensional changes and structural deformation, weakening the sealing performance. Furthermore, chemicals in the water can react with the sealing device 300, causing corrosion and deteriorating material properties. Furthermore, the impact of water flow can damage the lubricating film within the sealing groove, reducing lubrication effectiveness.

[0067] The surface portion of sealing device 300 is exposed to prolonged sunlight. The ultraviolet rays in solar radiation can break the molecular chains of the sealing material, causing material aging, reducing its flexibility and elasticity, and degrading sealing performance. Sunlight can significantly increase the surface temperature of the device. The repeated temperature swings between day and night can cause stress fatigue in the material due to thermal expansion and contraction, accelerating cracking and damage, and affecting the proper functioning of sealing device 300.

[0068] However, existing technologies lack effective means to distinguish and address different forms of wear, making it difficult to formulate and implement targeted maintenance strategies. This results in poor overall maintenance of the sealing device 300, further impacting the long-term stable operation of the gate. Therefore, the electromechanical integrated gate sealing structure provided in an embodiment of the present invention includes a protective device 400, which is used to provide differentiated protection for the sealing device 300.

[0069] Specifically, when the door body 200 is in a closed state, the above-water portion of the sealing device 300 is a sun protection area, and the underwater portion of the sealing device 300 is a waterproof area.

[0070] Protective device 400 includes a waterproof coating unit 410 and a sunscreen coating unit 420. A driving device causes waterproof coating unit 410 to apply waterproof coating to the waterproof area of ​​sealing device 300, while sunscreen coating unit 420 applies sunscreen coating to the sunscreen area of ​​sealing device 300. A sealing line separates the waterproof coating and the sunscreen coating on sealing device 300, and this sealing line is aligned with the water level.

[0071] When the first sealing belt 311 and the second sealing belt 312 are engaged and disengaged, the driving device drives the first sealing belt 311 and the second sealing belt 312 to rotate so that the protective device 400 is coated with different coatings in sequence according to the water level. Figure 3 As shown in , when the driving device drives the first sealing strip 311 to rotate clockwise from the inside to the outside, the waterproof coating unit 410 is first used to apply the waterproof coating to the waterproof area of ​​the first sealing strip 311. Then, the waterproof coating unit 410 stops, and the sunscreen coating unit 420 starts and continues to apply the waterproof coating along the cut-off line, so that the sunscreen area of ​​the first sealing strip 311 is coated with the sunscreen coating. Similarly, when the driving device drives the second sealing strip 312 to rotate counterclockwise from the inside to the outside, the waterproof coating unit 410 is first used to apply the waterproof coating to the waterproof area of ​​the second sealing strip 312. Then, the waterproof coating unit 410 stops applying the waterproof coating, and the sunscreen coating unit 420 continues to apply the waterproof coating along the cut-off line, so that the sunscreen area of ​​the second sealing strip 312 is coated with the sunscreen coating.

[0072] And when the water level changes, multiple coatings are re-applied according to the water level, and the position of the sealing boundary line is adjusted to ensure that the sealing boundary lines of the first sealing tape 311 and the second sealing tape 312 are aligned.

[0073] The waterproof coating forms a continuous, dense waterproof film on the surface of the sealing device 300, preventing moisture from penetrating into the interior of the sealing device 300 and thus preventing moisture intrusion. The sunscreen coating converts ultraviolet rays into heat energy or reflects them away, reducing their penetration into surfaces and thus reducing the damaging effects of ultraviolet rays on the sealing device 300.

[0074] Therefore, by coating the sealing device 300 with different protective coatings, precise maintenance of the sealing device 300 is achieved, and the overall performance and durability of the sealing device 300 are effectively improved.

[0075] It is understood that the waterproof coating can include a silicone-modified polyurethane coating and lithium-based grease. The silicone-modified polyurethane coating can reduce the rate of microbial attachment. The lithium-based grease filling maintains a lubricating film thickness of ≥ 0.3 mm, thereby protecting the sealing device 300 from hydraulic erosion.

[0076] The sunscreen coating can be made from a fluororubber coating containing 2% carbon nanotubes, a silicone oil protective agent containing a benzotriazole UV absorber, and a molybdenum disulfide + graphite composite dry film lubricant. Spraying the fluororubber coating containing 2% carbon nanotubes can increase UV shielding efficiency to 95%. Applying the silicone oil protective agent containing a benzotriazole UV absorber can resist oxidation and slow the rate of cracking on the surface of the sealing device 300. Using the molybdenum disulfide + graphite composite dry film lubricant can reduce dry friction between the first sealing strip 311 and the second sealing strip 312.

[0077] It should be noted that the amount of paint should refer to the volume between the first sealing tape 311 and the second sealing tape 312 to prevent overfilling and causing the door body 200 to become stuck.

[0078] It is understandable that the positional relationship between the waterproof coating unit 410 and the sunscreen coating unit 420 can be diverse. For example, the first sealing tape 311 equipped with the sunscreen coating unit 420 can be located above the waterproof coating unit 410 or below the waterproof coating unit 410. The driving device first drives the sunscreen coating unit 420 to coat the first sealing tape 311, and then drives the waterproof coating unit 410 to coat the first sealing tape 311.

[0079] However, the positional relationship between the waterproof coating unit 410 and the sunscreen coating unit 420 should be such that the sunscreen area of ​​the sealing device 300 is coated with the sunscreen coating, and the waterproof area of ​​the sealing device 300 is coated with the waterproof coating.

[0080] In one embodiment, when the door body 200 is in the open state, the rotation of the first sealing strip 311 will cause a temporary area of ​​the first sealing strip 311 to be exposed to the water flow. The first sealing strip 311 in the temporary area is directly subjected to the scouring effect of the water flow. The long-term scouring of the water flow will gradually wear out the first sealing strip 311, reduce the sealing accuracy of the first sealing strip 311, and affect the water-stopping effect of the electromechanical integrated gate sealing structure. Based on this, Figure 4-Figure 9 As shown, the protection device 400 further includes a temporary coating unit 430 , which is used to apply temporary coating on a temporary area of ​​the first sealing strip 311 to buffer the scouring effect of water flow on the first sealing strip 311 .

[0081] Specifically, a temporary coating unit 430 is provided inside the gate body 100 , so that the temporary coating unit 430 is located at the lower end inside the gate body 100 , and can apply temporary coating to the first sealing tape 311 along the cut-off line of the waterproof coating.

[0082] When the door body 200 is in the opening operation, the driving device drives the first sealing belt 311 to rotate, and the first sealing belt 311 rotates counterclockwise from the inside to the outside, so that the temporary area of ​​the first sealing belt 311 contacts the water surface. During the rotation of the first sealing belt 311, the temporary coating unit 430 will apply temporary coating to the temporary area of ​​the first sealing belt 311, so that the temporary coating can form a protective film on the first sealing belt 311, effectively reducing the direct erosion of the first sealing belt 311 by the water flow.

[0083] When the door body 200 is in a closing operation, the temporary area coated with the temporary paint will rotate clockwise from outside to inside to the inside of the gate body 100 as the first sealing tape 311 rotates, and no longer contacts the water surface.

[0084] Therefore, by setting up a temporary paint unit 430, when the door body 200 is in the open state, a layer of temporary paint is attached to the temporary area of ​​the first sealing strip 311, which can effectively buffer the scouring effect of water flow on the first sealing strip 311 and significantly reduce the degree of wear of the first sealing strip 311.

[0085] It is understood that the temporary coating is primarily made of materials such as oily wax or grease-based coatings that are hydrophobic, easy to remove, and have low adhesion properties. This allows the temporary coating to form a physical barrier layer on the surface of the first sealing tape 311, preventing water penetration and being able to withstand short-term water erosion. After curing, the temporary coating becomes semi-solid or ointment-like and can be physically scraped off using tools such as scrapers and spatulas, without the need for chemical solvents. At the same time, the temporary coating has a weak bond with the substrate, preventing damage to the protected surface.

[0086] In one embodiment, during actual use of the sealing device 300, the sidewalls of the first sealing strip 311 and the second sealing strip 312 are exposed and subject to continuous water erosion, UV radiation, chemical corrosion, and friction with surrounding structures. If the sidewalls become worn, corroded, or deformed, the structural integrity and sealing properties of the sealing device 300 may be compromised, leading to leakage of the medium through gaps in the sidewalls, thereby compromising the sealing performance of the sealing device 300.

[0087] Based on this, Figure 4-Figure 9 As shown, the protection device 400 includes a plurality of paint cartridges 440 , which are used to store a plurality of paints and are capable of coating the outer peripheral wall surface and the side wall surface of the first sealing band 311 and the second sealing band 312 .

[0088] Specifically, the coating cartridge 440 is provided with a cartridge head, which is in close contact with the outer peripheral wall and side wall of the sealing device 300 to apply coating to the side wall of the first sealing belt 311 and the second sealing belt 312 .

[0089] The barrel head of the paint cartridge 440 is made of a flexible and resilient polymer material such as silicone or thermoplastic elastomer. A soft lip is located around the edge of the barrel head. When the barrel head approaches the sealing device 300, the lip deforms under pressure, fitting tightly against the surface of the sealing device 300 and effectively preventing paint from spilling. Even with slight indentations or curvatures on the surface of the sealing device 300, the lip deforms adaptively, ensuring a secure seal, improving paint utilization, and ensuring uniform and stable coating.

[0090] Therefore, by providing a paint barrel 440 filled with different paints, accurate coating of different paints can be achieved, and the paint barrel 440 can coat the side wall surfaces of the first sealing band 311 and the second sealing band 312, reducing the risk of leakage caused by damage to the side wall, and significantly enhancing the sealing performance of the sealing device 300.

[0091] In one embodiment, when the water level changes, it is necessary to remove the coating already applied to the sealing device 300 and reapply multiple coatings to adjust the sealing boundary line. Figure 4-Figure 9 As shown, the protective device 400 includes a roller brush 450, which is used to clean the paint on the surface of the sealing device 300 when the paint of the sealing device 300 needs to be replaced.

[0092] Specifically, a roller brush 450 is installed between the first sealing strip 311 and the gate body 100, and between the second sealing strip 312 and the door body 200. The main body of the roller brush 450 is configured as a soft-bristled brush structure, which provides high conformability and cleaning flexibility. Made of soft nylon with excellent elasticity and toughness, the soft-bristled brush structure effectively removes debris and old coatings from the seal during operation. This also prevents the roller brush 450 from scratching the surface of the sealing device 300.

[0093] When the roller brush 450 is in a stationary state, the bristles naturally droop under the action of gravity. This natural shape ensures that when the roller brush 450 is not in a working state, unnecessary wear and tear will not be caused to the sealing device 300 due to the hard contact of the bristles.

[0094] The drive mechanism for roller brush 450 utilizes a built-in motor located within the roller brush 450, providing stable rotational power. The motor's speed can be precisely controlled via an external controller, allowing for efficient and precise cleaning based on various operating requirements, such as the surface material of the sealing device 300 and the thickness of the coating to be removed.

[0095] Therefore, by providing the roller brush 450 , not only can various coatings on the sealing device 300 be removed, but also foreign matter covering the surface of the sealing device 300 can be cleaned.

[0096] In other embodiments where the roller brush 450 is not provided, other paint removal devices, such as chemical paint stripping devices, sandblasting devices, etc., can be used to remove the paint applied to the sealing device 300 so as to re-apply new paint for protection.

[0097] In one embodiment, when the electromechanical integrated gate sealing structure is in operation, a high water level side and a low water level side are formed on both sides. Figures 1-9 As shown, the multiple sealing devices 300 include a first sealing device 310 and a second sealing device 320. The first sealing device 310 adjusts the sealing boundary line according to the water level on the high water level side, and the second sealing device 320 adjusts the sealing boundary line according to the water level on the low water level side. The first sealing device 310 is located outside the second sealing device 320.

[0098] Because the water pressure on the high water level side is significantly higher than that on the low water level side, under the action of the water pressure, the door body 200 is pushed toward the gate body 100, causing the first sealing belt 311 and the second sealing belt 312 to be squeezed against each other and fit more tightly.

[0099] Under high water pressure, a slight gap may appear between the door body 200 and the gate body 100 on the high water level side, causing the water flow on the high water level side to contact the first sealing device 310. Therefore, the first sealing device 310 automatically adjusts the sealing boundary line according to the water level change on the high water level side.

[0100] The water flow pressure on the low water level side is relatively small, and the water flow mainly contacts the second sealing device 320. Therefore, the second sealing device 320 automatically adjusts the sealing boundary line according to the water level change on the low water level side.

[0101] Therefore, by setting the first sealing device 310 and the second sealing device 320, the sealing boundary line is precisely adjusted according to different water levels to ensure that the water flow can be effectively blocked under different water level conditions, maintain the stability and reliability of the sealing device 300, and meet the operation requirements of the water conservancy project.

[0102] In one embodiment, Figure 1-Figure 3 As shown, the electromechanical integrated gate sealing structure further includes a water level adaptive regulating device, which is used to adjust the position of the sealing boundary line on the sealing device 300 according to the water level.

[0103] Specifically, the water level adaptive adjustment device includes a water level sensor and a controller. The water level sensor is used to detect the real-time water level. The controller adjusts the sealing boundary line to be level with the current water level line according to the signal of the water level sensor.

[0104] Therefore, by setting up a water level adaptive adjustment device, it is ensured that the sealing device 300 can fit tightly with the door body 200 and the gate body 100 under various water level conditions, minimizing leakage in gaps caused by water level fluctuations and effectively improving the sealing performance of the gate.

[0105] In one embodiment, Figure 4-Figure 9 As shown, the door body 200 is provided with a guide wheel 210 , the gate body 100 is provided with a protrusion 110 , and the first sealing belt 311 and the second sealing belt 312 are disengaged through the cooperation of the guide wheel 210 and the protrusion 110 .

[0106] Specifically, both sides of the door body 200 are located in the groove of the gate body 100, and a plurality of guide wheels 210 are provided on the side wall surface of the door body 200, and the guide wheels 210 are embedded in the groove of the gate body 100. A protrusion 110 is provided on the upper part of the groove of the gate body 100 to form a guide channel.

[0107] When the door body 200 is in a lower position, the guide wheel 210 is located at the lower part of the groove, and at this time the first sealing belt 311 and the second sealing belt 312 are tightly fitted together.

[0108] When the door 200 needs to be opened, the drive mechanism moves it upward, and the guide wheel 210, mounted on the sidewall of the door 200, rises synchronously. As the door 200 continues to move upward, the guide wheel 210 gradually enters the guide channel formed by the recessed protrusion 110 of the gate body 100. Constrained by the guide channel, the guide wheel 210 drives the door 200 to move laterally. This lateral movement of the door 200 causes the second sealing strip 312 to gradually move away from the first sealing strip 311, disengaging the first and second sealing strips 311, 312.

[0109] After the first sealing belt 311 and the second sealing belt 312 are disengaged, the driving device applies paint to the first sealing belt 311 and the second sealing belt 312 .

[0110] Therefore, by providing the guide wheel 210 and the protrusion 110 , it is ensured that the first sealing tape 311 and the second sealing tape 312 can accurately complete the fitting and separation actions.

[0111] In one embodiment, Figure 4-Figure 7 As shown, the first sealing belt 311 and the second sealing belt 312 are provided with meshing teeth 313 , and the meshing teeth 313 are used to achieve synchronous movement of the first sealing belt 311 and the second sealing belt 312 .

[0112] Specifically, the outer peripheral surfaces of the first sealing strip 311 and the second sealing strip 312 are each provided with mating teeth 313. The meshing teeth 313 are regular in shape and have a trapezoidal structure. Multiple adjacent meshing teeth 313 are equally spaced and arranged along the length of the first sealing strip 311 and the second sealing strip 312.

[0113] During installation, the meshing teeth 313 on the first sealing strip 311 correspond to the meshing teeth 313 on the second sealing strip 312 one by one and are embedded in each other to form a tight bite connection.

[0114] Thus, during the opening and closing process of the door body 200, the meshing connection of the meshing teeth 313 ensures that the first sealing strip 311 and the second sealing strip 312 always maintain synchronous movement. This prevents misalignment of the first sealing strip 311 and the second sealing strip 312 due to asynchronous movement, ensures the stability of the sealing device 300, and maintains good sealing performance.

[0115] At the same time, the meshing teeth 313 are tightly engaged, which reduces the gap between the first sealing belt 311 and the second sealing belt 312 , thereby reducing the risk of water leakage from the connection between the first sealing belt 311 and the second sealing belt 312 .

[0116] An embodiment of the present invention further includes an electromechanical integrated gate, which includes the electromechanical integrated gate sealing structure in the above embodiment.

[0117] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
