Description

Technical Field

[0001] This utility model relates to the field of sealing technology for stacked beam doors, and more specifically, to a sealing structure for a channel stacked beam door. Background Technology

[0002] Channel gate systems are key equipment used in water conservancy projects, municipal water supply and drainage, and industrial circulating water systems to control water flow, regulate water levels, or ensure smooth maintenance operations within channels. Their core consists of multiple independently hoistable horizontal gate panels, pre-set gate slots on both sides of the channel, and a sealing structure installed between the gate panels and the slots. In practical applications, multiple gate panels are stacked and embedded into the channel gate slots from top to bottom. The sealing structure fills the gaps between the sides of the gate panels and the inner wall of the slot, achieving the channel's water-blocking or flow-intercepting function. This maintains a stable water level during normal flow and blocks water flow during maintenance, providing a dry and safe working environment for channel cleaning and equipment maintenance. Furthermore, by removing some gate panels or adjusting the stacking height, the water flow can be flexibly controlled to adapt to different flow regulation needs under various operating conditions.

[0003] However, the sealing structures of existing canal gate systems mostly adopt a surface rigid design, commonly including rigid rubber strips fixed to the side of the gate, metal water seals, or hard plastic sealing blocks. These rigid sealing structures suffer from significant poor sealing performance in actual use. On the one hand, the inner wall of the canal gate slot is prone to unevenness due to long-term water erosion and silt wear, resulting in localized depressions and concrete spalling. Furthermore, slight tilting or installation deviations are inevitable during the hoisting and stacking of the gate. The rigid sealing structure cannot adaptively fill these non-standard gaps, resulting in a persistent gap between the gate and the gate slot. On the other hand, rigid seals are prone to deformation, cracking, or hardening due to water temperature changes, water pressure fluctuations, or long-term compression and wear, further widening the sealing gap and making leakage difficult to control. This not only affects the efficiency of canal maintenance but may also cause safety hazards due to water leakage eroding the canal foundation. In addition, the rigid sealing structure requires complete disassembly and replacement after wear, resulting in high maintenance costs and time consumption, seriously affecting the normal operation of the canal.

[0004] In summary, in order to improve the sealing reliability of the channel beam gate, reduce maintenance costs, and ensure stable channel operation, it is necessary to solve the problems that the existing rigid sealing structure cannot adaptively fill non-standard gaps, is easily damaged leading to difficult-to-control leakage, and is inconvenient to maintain. The goal is to reduce the leakage of the beam gate, make maintenance operations more convenient, and enable it to work stably for a long time in accordance with channel conditions. Utility Model Content

[0005] The present invention provides a channel beam gate sealing structure, which aims to solve the problems of existing rigid sealing structures being unable to adaptively fill non-standard gaps, being easily damaged leading to uncontrollable leakage, and being inconvenient to maintain.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a channel stacked beam door sealing structure, including a door groove, embedded grooves at both ends of the inner side of the door groove, multiple stacked gate plates disposed in the embedded grooves, reserved slots on both sides of the gate plates, empty slots disposed on both sides of the inner side of the door groove and communicating with the corresponding embedded grooves and reserved slots, a T-shaped reinforcing plate fixedly connected in the empty slot, rubber airbags disposed in each group of connected reserved slots and empty slots, thickened positioning edges of the airbags fixedly connected to the rubber airbags, two sets of alignment mechanisms installed on both sides of the door groove, a mounting plate fixedly connected to the rear side of the top of the door groove, and a portable compressor fixedly connected to the mounting plate by bolts. The number of rubber airbags in each group of reserved slots and empty slots is set to two, and the total number of rubber airbags on both sides is four. The two rubber airbags in the same group are separated on both sides by the T-shaped reinforcing plate. The output end of each set of alignment mechanisms is connected to the thickened positioning edges of the two airbags on the same side. The alignment mechanism is used to drive the thickened positioning edges of the airbags to move along a preset trajectory. The portable compressor is used to fill each rubber airbag with compressed gas.

[0007] In a preferred embodiment, each alignment mechanism includes a lifting component whose output end is connected to the thickened positioning edges of two airbags on the same side, and a driving component whose output end is connected to the input end of the lifting component. The driving component drives the two thickened positioning edges of the airbags to move along a preset trajectory through the lifting component.

[0008] In a preferred embodiment, the lifting assembly includes a threaded rod rotatably connected in a slot, a lifting block threadedly connected to the outside of the threaded rod, two Velcro rough surfaces fixedly connected to the surface of the lifting block, and Velcro hook surfaces fixedly connected to the lower part of the thickened positioning edges of the corresponding two airbags, with the two Velcro rough surfaces and the two Velcro hook surfaces respectively connected to each other.

[0009] In a preferred embodiment, the drive assembly includes a gear 1 rotatably connected to the top of the door slot, a fixed plate fixedly connected to the outside of the door slot, a motor fixedly connected to the fixed plate, and a gear 2 fixedly connected to the output end of the motor. The gear 2 and the gear 1 are meshed together. The gear 1 is fixedly connected to a threaded rod via a shaft. The motor is used to drive the gear 2 to rotate.

[0010] In a preferred embodiment, an inner air plate is fixedly connected to the output end of the portable compressor. Four connecting pipes are fixedly connected to the outer side of the inner air plate in a circumferential array. Each connecting pipe is equipped with a solenoid valve, and the four connecting pipes are respectively connected to four rubber air bags by connecting pipes.

[0011] In a preferred embodiment, the thickened positioning edge of the airbag is embedded between the T-shaped reinforcing plate and the inner wall of the slot, and the thickened positioning edge of the airbag is foldable.

[0012] In a preferred embodiment, two storage boxes are fixedly connected to the upper end of the top frame, and the upper end of the storage boxes is provided with a cover.

[0013] The beneficial effects of this utility model are as follows: This invention utilizes four sets of rubber airbags adapted to the gap between the gate slot and the gate plate, along with a portable compressor to regulate air pressure. Compared to traditional rigid rubber strips and metal water seals, the flexible rubber airbags can expand and self-fill non-standard gaps in the inner wall of the channel gate slot caused by erosion and wear, such as depressions and concrete spalling. Simultaneously, it offsets minor tilting deviations during gate plate hoisting and stacking. Furthermore, the T-shaped reinforcing plate separates and limits the rubber airbags, and the independent inflation function controlled by a solenoid valve ensures stable pressure in each airbag. Even if one rubber airbag is damaged, the other can still provide a good seal, keeping leakage within a standard range. This solves the problems of rigid seals, which are difficult to control and prone to causing channel foundation erosion, significantly improving the sealing reliability of the stacked beam gate.

[0014] This utility model, through its designed alignment mechanism (including a lifting component and a driving component), can carry the bottom of the rubber airbag to a preset lowest position, effectively avoiding the problem of the rubber airbag getting stuck in the middle of the door groove during installation. This reduces the difficulty of installation and shortens the installation time, while also avoiding the problem of excessive local gaps caused by airbag jamming, further ensuring the complete fit of the sealing surface and indirectly improving the sealing effect.

[0015] The rubber airbag and the thickened positioning edge of the fixed connection airbag in this utility model adopt a foldable design. When the stacked beam door does not require sealing operation, the rubber airbag can be deflated and folded to avoid aging and deformation caused by the airbag being under tension or compression for a long time. At the same time, the folded rubber airbag can be stored in the storage box and matching cover to isolate the airbag from the erosion of mud and sewage in the channel, reduce the wear and mold growth on the surface of the airbag, extend the service life of the rubber airbag, and the storage process is convenient without taking up extra storage space, thus ensuring the reuse of the airbag in the future.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6 A channel stacked beam gate sealing structure includes a gate slot 1, embedded grooves 2 at both ends of the inner side of the gate slot 1, multiple stacked gate plates 3 disposed in the embedded grooves 2, reserved slots 5 on both sides of the gate plates 3, empty slots 6 on both sides of the inner side of the gate slot 1 and communicating with the corresponding embedded grooves 2 and reserved slots 5, T-shaped reinforcing plates 10 fixedly connected in the empty slots 6, rubber airbags 7 disposed in each set of connected reserved slots 5 and empty slots 6, thickened positioning edges 8 of the airbags fixedly connected to the rubber airbags 7, two sets of alignment mechanisms installed on both sides of the gate slot 1, and a fixed... The mounting plate 11 is fixedly connected to the top rear side of the door slot 1, and the portable compressor 12 is fixedly connected to the mounting plate 11 by bolts. The number of rubber airbags 7 in each group of reserved slots 5 and empty slots 6 is set to two, and the total number of rubber airbags 7 on both sides is four. The two rubber airbags 7 in the same group are separated on both sides by T-shaped reinforcing plates 10. The output end of each group of alignment mechanism is connected to the thickened positioning edge 8 of the two airbags on the same side. The alignment mechanism is used to drive the thickened positioning edge 8 of the airbag to move along the preset trajectory. The portable compressor 12 is used to fill each rubber airbag 7 with compressed gas.

[0025] It should be noted that the gate slot 1 needs to reserve a clearance for the lifting and lowering of the gate plate 3. The width of the embedded slot 2 should match the thickness of the gate plate 3. The slot opening should be rounded to prevent scratches on the gate plate 3 during hoisting. When stacking the gate plates 3, add an elastic sealing gasket to prevent water leakage at the joint. The reserved slot 5 should be aligned longitudinally to ensure a smooth airbag installation channel and avoid jamming. The height of the empty slot 6 should cover the water-blocking height of the gate slot 1 to accommodate the inflation of the airbag. The T-shaped reinforcing plate 10 is fixed to the empty slot 6 with 304 stainless steel, separating the airbags to form a double seal, while also enhancing the impact resistance of the gate slot 1. There are four airbags on both sides, with the length of each matching the height of the gate plate 3. The contact surface is roughened to prevent water flow impact and displacement. The double sealing design can prevent a sudden increase in water leakage caused by leakage of a single airbag. Select a dual power supply model with high-voltage output and low-voltage protection to adapt to outdoor scenarios. Add rubber shock-absorbing pads during installation to reduce the impact of vibration on the stability of the gate plate 3.

[0026] Refer to the instruction manual appendix Figure 4 Each alignment mechanism includes a lifting component whose output end is connected to two corresponding thickened positioning edges 8 of the airbags on the same side, and a drive component whose output end is connected to the input end of the lifting component. The drive component drives the two thickened positioning edges 8 of the airbags to move along a preset trajectory through the lifting component.

[0027] It should be noted that the two sets of alignment mechanisms are synchronized through the same controller, such as a PLC, to avoid uneven sealing caused by inconsistent installation heights of the airbags on both sides. The inner wall of the empty slot 6 is provided with a guide groove to ensure that the positioning edge of the airbag moves along the preset trajectory. A limit block is provided at the bottom, and the motor 907 automatically cuts off power after contact to prevent the airbag from being squeezed and damaged.

[0028] Refer to the instruction manual appendix Figure 4 and Figure 6 The lifting assembly includes a threaded rod 901 rotatably connected in the slot 6, a lifting block 902 threadedly connected to the outside of the threaded rod 901, two Velcro rough surfaces 903 fixedly connected to the surface of the lifting block 902, and Velcro hook surfaces 904 fixedly connected to the lower part of the corresponding two airbag thickened positioning edges 8. The two Velcro rough surfaces 903 are respectively connected to the two Velcro hook surfaces 904.

[0029] It should be noted that the threaded rod 901 is made of 40Cr material to prevent rust, and the trapezoidal thread is selected to be wear-resistant and prevent jamming. The lifting block 902 is made of reinforced engineering plastic, and the mating surfaces are regularly lubricated to reduce friction. The Velcro is made of industrial-grade water-resistant material and is firmly attached with high-temperature resistant epoxy resin. The spacing matches the vertical arm of the T-shaped reinforcing plate 10 to prevent the airbags from squeezing each other when moving.

[0030] Refer to the instruction manual appendix Figure 1 and Figure 4The drive assembly includes a gear 905 rotatably connected to the top of the door slot 1, a fixed plate 906 fixedly connected to the outside of the door slot 1, a motor 907 fixedly connected to the fixed plate 906, and a gear 908 fixedly connected to the output end of the motor 907. The gear 908 and the gear 905 are meshed together. The gear 905 is fixedly connected to the threaded rod 901 through a shaft. The motor 907 is used to drive the gear 908 to rotate.

[0031] It should be noted that gear oil should be applied to the meshing joints of gear 1 (905) and gear 2 (908) and replaced periodically. Dust covers should be added to the outside to prevent mud and sand from getting stuck. A stepper motor 907 with overcurrent and overheat protection should be selected. The output shaft and gear should be connected with a key and fixed with set screws to prevent slippage. The fixing plate 906 should be made of steel plate of sufficient thickness and fixed with expansion bolts to prevent shaking.

[0032] Based on another embodiment of the two sets of alignment mechanisms, the design of threaded rod 901, lifting block 902, hook and loop fastener 903 and hook and loop fastener 904 can be retained, gear 2 908 can be removed, and pulleys can be used to replace the two gears 1 905. A belt can be used to drive the two gears 1 905. Only one motor 907 can be selected to connect to the shaft of any one of the gears 1 905. In this way, the actuation of the rubber airbags 7 on both sides can be synchronized, and one less motor 907 can be used to reduce costs.

[0033] Refer to the instruction manual appendix Figure 1 and Figure 5 An inner air plate 13 is fixedly connected to the output end of the portable compressor 12. Four connecting pipes 14 are fixedly connected to the outer side of the inner air plate 13 in a circular array. A solenoid valve 15 is installed on each connecting pipe 14, and connecting pipes 16 are connected between the four connecting pipes 14 and the four rubber air bags 7 respectively.

[0034] It should be noted that the inner cavity plate 13 is made of lightweight and corrosion-resistant material. After welding the connecting pipe 14, a pressure test is performed to prevent air leakage and ensure reliable air circuit sealing. The connecting pipe 16 is made of high-pressure PU tubing that is resistant to aging and hydrolysis. It is fixed along the door groove 1 and a length allowance is reserved to prevent pulling and breakage. The connector uses a quick-connect design to facilitate airbag disassembly and replacement.

[0035] In another embodiment based on the internal hollow plate 13 design, a pressure sensor can be installed on each connected connecting pipe 14, connected to an intelligent controller with a display screen and audible and visual alarms, displaying the pressure value in real time, and alarming when the pressure is below the threshold. It is also equipped with a spare small high-pressure gas cylinder for manual inflation in case of a sudden power outage.

[0036] Refer to the instruction manual appendix Figure 6 The thickened positioning edge 8 of the airbag is embedded between the inner wall of the T-shaped reinforcing plate 10 and the hollow groove 6, and the thickened positioning edge 8 of the airbag is foldable.

[0037] It should be noted that the thickened positioning edge 8 of the airbag uses a composite structure of "rubber + polyester cord reinforcement layer", which has high tear resistance and adopts accordion-style pre-compression crease. The inner side of the crease is rounded to prevent cracking and meets the requirements of multiple folding.

[0038] Refer to the instruction manual appendix Figure 1 and Figure 2 The top of the top frame 4 is fixedly connected to two storage boxes 17, and the top of the storage boxes 17 is provided with a cover 18.

[0039] It should be noted that the storage box 17 is made of impact-resistant and aging-resistant plastic or stainless steel, depending on the working conditions. The inside is lined with a cushioning pad to prevent airbag wear and can accommodate the folded airbag.

[0040] Working principle: After the gate slot 1 is fixed, the gate plate 3 is stacked and embedded into the embedded slot 2, and the reserved slot 5 is aligned with the empty slot 6. The T-shaped reinforcing plate 10 separates the empty slot 6. The rubber airbags 7 in the storage box 17 are taken out and connected in sequence through the Velcro surface 903 and the Velcro hook surface 904. The thickened positioning edge 8 of the airbag is fixed to the lifting block 902. The motor 907 in the alignment mechanism is started to drive the gear 2 908 to rotate. The gear 2 908 drives the gear 1 905 to rotate. The gear 1 905 further drives the threaded rod 901 to rotate. The lifting block 902 drives the rubber airbag 7 to be embedded in the bottom position of the corresponding slot. The portable compressor 12 is started, and the four rubber airbags 7 are inflated through the inner empty plate 13 and the connecting pipe 14, so that they fit the gate plate 3 and the gate slot 1 to form a seal and prevent water leakage.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
