Description

Technical Field

[0001] This utility model relates to the field of channel gate technology, and more specifically, to a corrugated plate channel gate. Background Technology

[0002] Channel gates play a crucial role in wastewater treatment systems. They not only control the flow rate and direction of wastewater but also prevent leaks and environmental pollution. Furthermore, gates provide rapid response and closure capabilities in emergencies, ensuring the safe and stable operation of the wastewater treatment system.

[0003] Currently, the mainstream structure of channel gate panels is a flat steel plate with "well"-shaped reinforcing ribs. Its structural strength can meet the requirements of working conditions, but it consumes a lot of materials and the overall weight of the gate is large. Therefore, the gate opening and closing requires a large-power motor, which does not conform to the development trend of green energy conservation.

[0004] A search revealed Chinese patent application number 2017109908773, which discloses a lightweight corrugated plate gate, comprising a gate slot and a gate body. The gate slot consists of a top water-stop groove, side water-stop tracks, a bottom water-stop beam, a bottom water-stop seat, and a guide locking block. The gate body is plate-shaped and includes a top beam, two side beams, a bottom beam, a corrugated panel, a support beam, and lifting lugs. The corrugated panel extends along the opening and closing direction of the gate. This application proposes a lightweight gate panel design, but it still requires a support beam to be installed on the corrugated panel. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the technical problem of the large weight of existing channel gate panels, this utility model provides a corrugated plate channel gate. This solution, by setting the gate panel as a corrugated plate, with the extension direction of the corrugations designed perpendicular to the opening and closing direction of the gate, not only effectively reduces the self-weight of the gate panel but also minimizes its deformation under pressure, thereby ensuring the strength of the gate panel.

[0007] 2. Technical solutions adopted

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] The present invention provides a corrugated plate channel gate, including a gate panel that can be slidably installed in a gate frame to open and close the water flow channel; the gate panel includes a corrugated panel and side beams located around the corrugated panel, and the corrugated extension direction of the corrugated panel is perpendicular to the opening and closing direction of the gate.

[0010] There are also wedging and sealing components between the door panel and the door frame. The wedging components are used to tighten the door, and the sealing components are used to stop water from entering.

[0011] Furthermore, the waveform panel contains multiple arc segments distributed laterally, with adjacent arc segments connected by straight segments. The arc segments and straight segments together form a flat-topped sine wave, and all of their waveforms bulge towards the water-facing side.

[0012] Furthermore, the side beam includes an upper side beam, a lower side beam, and two side beams that enclose a hollow rectangular frame. The outer contour lines of the upper sealing plate at the bottom of the upper side beam and the lower sealing plate at the top of the lower side beam match the waveforms of the top and bottom surfaces of the waveform panel, respectively, and are fixedly connected accordingly.

[0013] Furthermore, the two sides of the waveform panel are straight line segments.

[0014] Furthermore, the wedging component includes an upper wedge, a lower wedge, an upper limit rod, and a lower limit rod. Each side beam has an upper wedge and a lower wedge on its water-facing surface. The door frame has an upper limit rod and a lower limit rod corresponding to the upper and lower wedges, respectively. The upper wedge and the upper limit rod, and the lower wedge and the lower limit rod are pressed together to achieve wedging.

[0015] Furthermore, the upper and lower wedges in a single side beam are spaced apart along the height direction and staggered along the direction of the waveform extension. The lower wedge is located on the side of the upper wedge closer to the waveform panel. The adjacent sides of the upper limit rod and the lower wedge are spaced apart along the direction of the waveform extension. And / or the upper limit rod and the lower limit rod are both round rods. And / or the upper and lower wedges are both triangular flat plates with their hypotenuses forming wedge surfaces. The angle between the hypotenuses forming the wedge surfaces and the opening and closing direction of the door panel is 8° to 12°.

[0016] Furthermore, the door frame includes a lower frame, a upper frame, and two side frames that enclose a hollow rectangular frame, with grooves in the two side frames for sliding the side beams.

[0017] Furthermore, the sealing component adopts a modular sealing part, which includes a sealing element and a pressure plate. The sealing element is fixedly installed on the side beam and the lower beam by the pressure plate. The sealing element used on the side beam is located in the groove. The sealing element is located on the back water surface and is a P-type rubber part.

[0018] Furthermore, the pressure plate is an integrally formed U-shaped plate; the seal matches the shape of the pressure plate; and / or the seal and the pressure plate are bonded together.

[0019] Furthermore, the channel gate includes a hoist, which drives the gate panel to slide relative to the gate frame via a lead screw; the upper frame is provided with a through groove for the lead screw to pass through.

[0020] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0021] (1) This utility model optimizes the design of the gate panel. Specifically, the corrugated panel is made of corrugated plate, and the corrugation extension direction is perpendicular to the opening and closing direction of the gate. Compared with the traditional flat gate panel, it can withstand higher static water pressure, thereby improving the gate strength and reducing the amount of deformation under pressure. In addition, the use of corrugated plate ensures strength while reducing its weight by 30% to 40% compared with flat plate, reducing the power required to open and close the gate.

[0022] (2) This utility model prevents interference between the wedges and other limiting rods by setting a wedge-tightening component between the door panel and the door frame, and by optimizing the relative positions of the upper wedge, lower wedge, upper limit rod, and lower limit rod, thereby increasing the number of wedges and limiting rods that can be used. Furthermore, sealing components are set between the left and right sides and the bottom of the door panel and the door frame to improve sealing performance. Moreover, the cooperation between the wedges and the limiting rods ensures that the sealing components on both sides fit tightly with the door frame. Attached Figure Description

[0040] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation.

[0041] Explanation regarding direction: See reference. Figure 1 From the perspective shown, the "waveform extension direction" referred to in this utility model refers to the horizontal direction along the line connecting the two side frames 401 in the door frame 4, also known as the "lateral direction"; the opening and closing direction of the gate refers to the vertical direction.

[0042] This embodiment provides a corrugated plate channel gate, see reference. Figure 1-3As shown, the gate includes a door panel 3, which can be slidably installed inside the door frame 4 to open and close the water flow channel; the door panel 3 includes a corrugated panel 302 and side beams located around the corrugated panel 302, the corrugation extension direction of the corrugated panel 302 is perpendicular to the opening and closing direction of the gate; a wedge-tightening component and a sealing component are also provided between the door panel 3 and the door frame 4, the wedge-tightening component is used for wedge tightening; the sealing component is used for water stop.

[0043] The corrugated panel 302 is made of corrugated plate, with its corrugation extending perpendicular to the opening and closing direction of the gate. Compared with a flat gate panel, it can withstand higher static water pressure, thereby increasing the gate's strength and reducing deformation under pressure. In addition, the use of corrugated plate ensures strength while reducing its weight by 30% to 40% compared to a flat plate, thus reducing the power required to open and close the gate.

[0044] For details, please refer to Figure 3 , Figure 4 As shown, the waveform panel 302 includes multiple arc segments distributed laterally. Adjacent arc segments are connected by straight segments. The arc segments and straight segments together form a flat-topped sine wave, and the waveforms all bulge towards the water-facing side.

[0045] The corrugated panel 302 is made of flat steel plate pressed by a mold. Its shape is a flat-topped sine wave. Compared with ordinary circular curves and trapezoidal curves, this type of waveform has higher structural stability and a longer service life. When intercepting sewage, the waveform extension direction of the corrugated panel 302 is perpendicular to the water flow direction.

[0046] More specifically, the side beams include an upper side beam 301, a lower side beam 305, and two side beams 306 that enclose a hollow rectangular frame. The outer contours of the upper sealing plate 3011 at the bottom of the upper side beam 301 and the lower sealing plate at the top of the lower side beam 305 respectively match the waveforms of the top and bottom surfaces of the wave panel 302 and are fixedly connected to each other to seal the top surface of the wave panel 302. The two side beams 306 are located on both sides of the wave panel 302 in the horizontal direction and are fixedly connected to each other.

[0047] The outer contours of the upper sealing plate 3011 and the lower sealing plate are closely fitted with the top and bottom waveforms of the waveform panel 302, which not only prevents sewage from leaking from the joint between the two, but also increases the structural stability of the waveform panel 302.

[0048] Preferably, the upper beam 301, the lower beam 305, and the two side beams 306 are all L-shaped bent angle steels, and the L-shaped bent angle steels are provided with reinforcing ribs between adjacent inner surfaces; thereby improving their stability.

[0049] When the upper beam 301 and the lower beam 305 adopt an L-shaped bent angle steel structure, the horizontal folded plates therein constitute the upper sealing plate 3011 and the lower sealing plate, respectively.

[0050] More preferably, the waveform panel 302 has straight segments of its waveform on both sides along the waveform extension direction, which facilitates the connection between the waveform panel 302 and the two side beams 306.

[0051] To further improve the stability of the connection between the corrugated panel 302 and the side beam, reinforcing ribs are provided between the straight section of the corrugated panel 302 and the upper side beam 301, the lower side beam 305, and the two side beams 306.

[0052] refer to Figure 3 , Figure 5 , Figure 6 As shown, in some embodiments, the wedging component includes an upper wedge 303, a lower wedge 304, an upper limit rod 402, and a lower limit rod 403. Each side beam 306 has an upper wedge 303 and a lower wedge 304 on its water-facing surface. The door frame 4 has an upper limit rod 402 and a lower limit rod 403 corresponding to the upper wedge 303 and the lower wedge 304, respectively. The upper wedge 303 and the upper limit rod 402, and the lower wedge 304 and the lower limit rod 403 are pressed together to achieve wedging.

[0053] Preferably, the upper wedge block 303 and the lower wedge block 304 in a single side beam 306 are distributed at intervals along the height direction and are staggered along the direction of waveform extension. The lower wedge block 304 is located on the side of the upper wedge block 303 close to the waveform panel 302. The upper limit rod 402 and the adjacent side of the lower wedge block 304 are spaced apart along the direction of waveform extension.

[0054] By optimizing the relative positions of the upper wedge 303, lower wedge 304, upper limit rod 402, and lower limit rod 403, as the door panel 3 descends relative to the door frame 4, because there is a gap between the adjacent sides of the lower wedge 304 and the upper limit rod 402 along the waveform extension direction, when the lower wedge 304 descends to the height corresponding to the upper limit rod 402, the lower wedge 304 and the upper limit rod 402 do not contact each other, thus preventing incorrect locking; as the door panel 3 continues to descend relative to the door frame 4, the upper wedge 303 and the lower wedge 304 contact the corresponding upper limit rod 402 and lower limit rod 403 respectively, and gradually wedge tight.

[0055] When the door panel 3 is closed, the upper wedge 303 and the upper limit rod 402, as well as the lower limit rod 403 and the lower wedge 304 cooperate to form a self-locking mechanism for the door panel 3.

[0056] Further preferred options, refer to Figure 6As shown, the upper limit rod 402 and the lower limit rod 403 are both cylindrical rods. The rods are made of stainless steel. Using rods as limiters has two advantages: firstly, when the wedge is wedged tightly with the rod, the required operating force is smaller; secondly, when the gate is opened, the rods are less likely to cause jamming, thus reducing the equipment failure rate.

[0057] More preferably, both the upper wedge 303 and the lower wedge 304 are triangular flat plates, with their hypotenuses forming wedge surfaces, and the angle between the hypotenuses forming the wedge surfaces and the opening and closing direction of the door panel 3 is 8° to 12°.

[0058] In other embodiments, the door frame 4 includes a lower frame 404, an upper frame 405, and two side frames 401 that enclose a hollow rectangular frame. The two side frames 401 are provided with grooves 4011 for sliding the side beam 306.

[0059] The groove 4011 in the two side frames 401 is preferably U-shaped, see reference. Figure 1 The viewing angle limits the left and right sides and the front and back sides of the door panel 3.

[0060] Specifically, the lower frame 404, upper frame 405, and two side frames 401 are all made of bent channel steel. The side frames 401 utilize the grooves formed by bending the channel steel to create internal sliding grooves 4011. The lower frame 404 is also made of bent channel steel, with the grooves formed by bending facing outwards from the empty rectangular frame formed by the side beams. (See reference...) Figure 1 The view shown is downward, and the top surface of the bottom border 404 is flat.

[0061] As a preferred embodiment of the sealing component, refer to Figure 7-10 As shown, the sealing component adopts a modular sealing part 5, which includes a sealing element 502 and a pressure plate 501. The sealing element 502 is fixedly installed on the side beam 306 and the lower side beam 305 by the pressure plate 501. The sealing element 502 used on the side beam 306 is located in the groove 4011. The sealing element 502 is located on the back water surface and is a P-type rubber part.

[0062] The sealing element 502 is fixedly installed on the side beam 306 and the lower beam 305. This modular sealing element 5 is particularly suitable for normally open gates, where the bottom end of the gate plate 3 is usually above the liquid level, thereby preventing the sealing element from being immersed in sewage for a long time and extending its service life.

[0063] Specifically, the pressure plate 501 has corresponding threaded holes between it and the side beam 306 and the lower beam 305, and the sealing element 502 is placed between the pressure plate 501 and the side beam 306 and the lower beam 305. The sealing element 502 is fixedly installed on the side beam 306 and the lower beam 305 by fixing screws.

[0064] As an extension, the shape of the pressure plate 501 is adapted to the shape formed by the side beam 306 and the lower beam 305 in the door panel 3. Specifically, the pressure plate 501 is an integrally formed U-shaped plate; the sealing element 502 matches the shape of the pressure plate 501; correspondingly, the sealing element 502 is U-shaped as a whole, preferably made of P-type rubber parts through hot vulcanization bonding to form an integrally formed U-shape. The pressure plate 501 is preferably made of 304 stainless steel. The sealing element 502 is preferably made of nitrile rubber or EPDM rubber.

[0065] As a further extension, the seal 502 and the pressure plate 501 are bonded together; this facilitates the replacement of the modular sealing part 5 and further improves the sealing performance.

[0066] The replacement process for the modular sealing part 5 is as follows: During use, when the modular sealing part 5 needs maintenance, slide the door panel 3 to the highest position, i.e., open the door panel 3, remove the fixing screws between the pressure plate 501 and the side beam 306 and the lower beam 305, remove the modular sealing part 5 as a whole, check whether the pressure plate 501 is damaged. If the pressure plate 501 is not damaged, it can be reused. Separate the pressure plate 501 from the seal 502, clean the surface of the pressure plate 501, and then bond the new seal 502 to the pressure plate 501. Then install the modular sealing part 5 in the corresponding position of the door panel 3. The replacement is complete. The entire replacement process is simple and quick.

[0067] As a further extension, the door frame 4 has multiple reinforcing hoops 406, which are spaced apart along the height direction and match the shape of the side frames 401. Accordingly, the reinforcing hoops 406 are U-shaped. The reinforcing hoops 406 are preferably located at the lower part of the side frames 401.

[0068] refer to Figure 1 As shown, the channel gate includes a hoist 1, which drives the gate panel 3 to slide relative to the gate frame 4 via a screw 2; the upper frame 405 is provided with a through groove for the screw 2 to pass through.

[0069] Preferably, the two upper frame edges 405 include two parallel and spaced-apart bent channel steels, the gap between the two bent channel steels forming a through groove for the lead screw 2 to pass through. Preferably, the bent grooves of the two bent channel steels are arranged facing outwards from each other.

[0070] This type of corrugated plate channel gate is suitable for open-type water channels, and its installation method is as follows:

[0071] (1) Measure the dimensions of the gate slots reserved in the channel. In civil engineering, gate slots are generally reserved on both sides and the bottom for installation. Steel plates need to be embedded in the gate slots on both sides. Before installing the gate, the width and depth of the gate slots need to be measured to determine whether the dimensions of the gate slots and the outer side of the gate frame 4 match. If the dimensions are not up to standard, they need to be adjusted again. If the dimensions are up to standard, the next step can be carried out.

[0072] (2) Lift the gate as a whole and insert it into the gate slot in the direction of the gate slot. At this time, it is necessary to determine the orientation of the gate. The side of the gate plate 3 with the wedge fastening part is the water-facing side. After adjusting the installation orientation, adjust the gate level and proceed to the next step.

[0073] (3) Weld and fix the side frame 401 in the door frame 4 to the pre-embedded steel plate in the door groove on both sides of the channel. After the welding is completed, the door groove needs to be poured with concrete for a second time. Use concrete to fill the door groove on both sides and the bottom door groove to be flush with the inner wall of the channel. After the second pouring, the concrete residue on the gate needs to be cleaned.

[0074] (4) Gate debugging: For manual gates, the gate hoist 1 can be operated to move the gate plate 3 up and down. Observe whether there is any jamming during the movement of the gate plate 3, whether the wedging component is under force after the gate plate 3 is closed, and whether the sealing component is tightly fitted. For electric gates, the gate plate 3 switch limit needs to be adjusted after the electric hoist is connected to the power.

[0075] When the gate is closed, the gate plate 3 gradually descends to the bottom of the gate frame 4. During this process, the wedges on both sides of the gate plate 3 gradually contact and wedge tightly with the corresponding limit rods in the gate frame 4. The sealing element 502 gradually presses against the bottom of the gate frame 4. At the same time, under the action of the wedge-tightening components, the gate plate 3 moves closer to the inner wall of the backwater side of the gate frame 4, and the sealing element 502 gradually presses against the gate frame 4. Thus, three seals are formed on the sides and bottom of the gate plate 3, and all sealing surfaces are pressed tightly together, achieving bidirectional sealing with excellent sealing performance. When the gate is closed, the corrugated plate bears the hydrostatic pressure. Due to the high overall strength and rigidity of the corrugated plate, the gate plate 3 is not easily deformed. Therefore, the sealing components will not be worn or damaged due to the deformation of the gate plate 3, improving the service life of the sealing components and thus improving the overall service life of the gate.

[0076] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
