Description

Technical Field

[0001] This utility model relates to the field of gate technology, specifically a high-efficiency sealing bidirectional water-stopping gate. Background Technology

[0002] A bidirectional water-stop gate is a special hydraulic device capable of stopping water flow in both directions. Its unique structural design ensures excellent sealing performance under varying water pressure conditions, making it suitable for various applications including urban water supply and drainage, flood control projects, sewage treatment plants, and hydroelectric power stations.

[0003] The sealing effect of current bidirectional water-stop gates mainly relies on the sealing strip on the gate body to fit tightly against the gate frame to form a seal and prevent water from flowing through. However, the gate body needs to slide up and down, which will cause the sealing strip and the gate frame to slide and rub against each other, resulting in wear. Since the sealing strip is fixedly installed on the gate body and its relative position does not change, the sealing strip continues to wear and become thinner, eventually creating a certain gap between it and the gate frame, affecting the sealing effect. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient, bidirectional, sealing gate to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency sealing bidirectional water-stop gate, comprising:

[0007] A lifting structure, wherein the lifting structure includes a crossbeam;

[0008] A gate frame, comprising a frame body, a crossbeam fixedly installed at the upper end of the frame body, guide grooves provided on the inner walls of both sides of the frame body, and spring clip grooves provided on the inner walls of both sides of the guide grooves.

[0009] The gate structure includes a double-arc gate plate, on both sides of which lifting slide bars are fixedly installed and slidably engaged with guide slide grooves, and on both sides of the lifting slide bars are fixedly installed sealing springs.

[0010] Furthermore, the lifting structure also includes:

[0011] A drive motor is fixedly installed on the rear edge of the crossbeam;

[0012] A worm gear box is fixedly installed on the middle of the upper surface of the crossbeam, and the worm inside the worm gear box is fixedly connected to the output end of the drive motor.

[0013] The transmission rod is fixedly sleeved at the middle part with the worm gear inside the worm gear box.

[0014] Furthermore, the lifting structure also includes:

[0015] A bevel gear, which is fixedly installed at both ends of the transmission rod;

[0016] A bevel gear disk that meshes with a bevel gear.

[0017] An internal threaded sleeve is fixedly fitted onto the lower edge of the outer surface of the internal threaded sleeve, and the internal threaded sleeve is rotatably mounted on the upper surface of the crossbeam via a bearing.

[0018] A lead screw, wherein the lead screw is screwed into an internal threaded sleeve;

[0019] The connecting end is fixedly installed at the lower end of the lead screw.

[0020] Furthermore, the gate frame also includes:

[0021] Bottom slot, the bottom slot being formed inside the bottom of the frame body;

[0022] A sealing groove is formed on one edge of the spring slide groove;

[0023] The water inlet trough is located at the front and rear edges of the guide slide opening and is connected to the spring slide trough.

[0024] Furthermore, the gate structure also includes:

[0025] A bottom clip is fixedly installed at the bottom of the double-arc gate plate;

[0026] Top bar, the top bar is fixedly installed on the upper surface of the double arc-shaped gate plate;

[0027] A connecting seat is fixedly installed on both ends of the upper surface of the top strip, and the connecting seat and the connecting end are interlocked with each other.

[0028] An internal support frame is fixedly installed inside the double-arc gate.

[0029] Furthermore, the gate structure also includes:

[0030] An auxiliary roller is rotatably mounted on the front and rear edges of one side of the lifting slide bar.

[0031] A sealing strip is fixedly installed on one edge of the sealing spring, and the sealing strip is slidably engaged with the sealing groove.

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] 1. Insert the double-arc gate into the main frame and install the crossbeam on the upper part of the main frame. After assembling the overall structure, install the overall structure at the water flow channel. The double-arc gate is an irregular box structure composed of two arc-shaped gate panels. The arc panels form a bidirectional arch structure to resist water pressure on both sides, effectively dispersing the water pressure load and improving the pressure resistance. At the same time, the sliding guide groove and the lifting slide are equipped with sliding spring grooves and sealing springs. The elasticity makes one side of the sealing spring tightly abut against the side surface of the spring groove at all times. With the sliding engagement of the guide groove and the lifting slide, the sealing and water-stopping effect is guaranteed.

[0034] 2. When the double-arc gate slides up and down, the auxiliary rollers roll on both sides of the guide groove, and the auxiliary lifting slide bar slides up and down. At the same time, the elasticity of the sealing spring pushes the sealing strip and the sealing groove to fit tightly against each other to ensure the sealing effect and avoid the reduction of sealing effect caused by sliding wear between the sealing strip and the sealing groove. Meanwhile, the impact water flow dispersed to both sides by the arc surface of the double-arc gate will flow into the space behind the sealing spring release direction under the guidance of the water inlet groove, and release the water flow impact force along the direction of the sealing spring release force, so as to prevent the sealing spring from shrinking under the impact of the water flow and affecting the sealing performance.

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figure 1-7 In this embodiment of the utility model, a high-efficiency sealing bidirectional water-stop gate includes a lifting structure 1, a gate frame 2, and a gate structure 3. The lifting structure 1 includes a crossbeam 101; the gate frame 2 includes a frame body 201, with the crossbeam 101 fixedly installed at the upper end of the frame body 201, and guide grooves 203 are provided on the inner walls of both sides of the frame body 201, with spring strip grooves 204 provided on the inner walls of both sides of the guide grooves 203; the gate structure 3 includes a double-arc gate plate 301, with lifting slide bars 305 fixedly installed on both sides of the double-arc gate plate 301 and slidably engaged with the guide grooves 203, and sealing spring strips 308 fixedly installed on both sides of the lifting slide bars 305.

[0045] Specifically, the double-arc gate 301 is inserted into the frame body 201 and the crossbeam 101 is installed on the upper part of the frame body 201. After the assembly of the overall structure is completed, the overall structure is installed at the water flow channel. The double-arc gate 301 is a special-shaped box structure composed of two arc-shaped gate panels. The arc-shaped panels form a bidirectional arch structure to resist the water pressure on both sides, effectively dispersing the water pressure load and improving the pressure resistance. At the same time, the sliding guide groove 203 and the lifting slide bar 305 are provided with sliding spring groove 204 and sealing spring 308. Through the elasticity, one side of the sealing spring 308 is always tightly pressed against the side surface of the spring groove 204. With the sliding engagement of the guide groove 203 and the lifting slide bar 305, the sealing and water-stopping effect is guaranteed.

[0046] Example 1

[0047] like Figure 1-2 As shown, in this embodiment, the lifting structure 1 further includes a drive motor 102, a worm gear box 103, a transmission rod 104, a bevel gear 105, a bevel gear disc 106, an internal threaded sleeve 107, a lead screw 108, and a connecting end 109. The drive motor 102 is fixedly installed on the rear edge of the crossbeam 101; the worm gear box 103 is fixedly installed on the middle of the upper surface of the crossbeam 101, and the worm inside the worm gear box 103 is fixedly connected to the output end of the drive motor 102; the transmission... The middle part of the rod 104 is fixedly sleeved with the worm gear inside the worm gear box 103; the bevel gear 105 is fixedly installed at both ends of the transmission rod 104; the bevel gear disc 106 meshes with the bevel gear 105; the lower edge of the outer surface of the internal threaded sleeve 107 is fixedly sleeved with the internal threaded sleeve 107, and the internal threaded sleeve 107 is rotatably installed on the upper surface of the crossbeam 101 through the bearing; the lead screw 108 is screwed and sleeved with the internal threaded sleeve 107; the connecting end 109 is fixedly installed at the lower end of the lead screw 108.

[0048] In this embodiment, the drive motor 102 drives the worm and worm gear inside the worm gear box 103 to control the rotation of the transmission rod 104. Then, the bevel gear 105 and bevel gear disc 106 rub the internal threaded sleeve 107 to rotate. The internal threaded sleeve 107 and the lead screw 108 are screwed together to control the lead screw 108 to move up and down. Then, the lead screw 108 pulls the gate structure 3 to move up and down to perform the gate opening and closing operation.

[0049] like Figure 4-5 As shown, in this embodiment, the gate structure 3 further includes a bottom clamp 302, a top bar 303, a connecting seat 304, and an internal support frame 307. The bottom clamp 302 is fixedly installed on the bottom of the double-arc gate plate 301; the top bar 303 is fixedly installed on the upper surface of the double-arc gate plate 301; the connecting seat 304 is fixedly installed on both ends of the upper surface of the top bar 303, and the connecting seat 304 and the connecting end 109 are interlocked; the internal support frame 307 is fixedly installed inside the double-arc gate plate 301.

[0050] In practice, the lower end of the lead screw 108 is connected to the connecting seat 304 through the connecting end 109, which pulls the double arc-shaped gate 301 to move up and down. The double arc-shaped gate 301 is designed as a hollow box structure to reduce weight. At the same time, there is an internal support frame 307 for grid-like internal support. When there is a weight requirement for the gate, sand and gravel or other fillers can be injected into each grid space formed by the internal support frame 307 during the production of the double arc-shaped gate 301 to adjust the weight.

[0051] Example 2

[0052] Based on Example 1, in order to compensate for the fact that the sealing spring 308 used as the force base of the sealing and water-stopping structure in Example 1 has a certain degree of mobility and may retract under the impact of water flow, thus affecting the sealing and water-stopping effect.

[0053] like Figure 3-7 As shown, in this embodiment, the gate frame 2 further includes a bottom slot 202, a sealing slot 205, and a water inlet groove 206. The bottom slot 202 is located on the inner bottom of the frame body 201; the sealing slot 205 is located on one side edge of the spring slide groove 204; the water inlet groove 206 is located on the front and rear sides of the opening of the guide slide groove 203 and is interconnected with the spring slide groove 204; the gate structure 3 further includes an auxiliary roller 306 and a sealing strip 309. The auxiliary roller 306 is rotatably installed on the front and rear sides of one side of the lifting slide bar 305; the sealing strip 309 is fixedly installed on one side edge of the sealing spring 308 and is slidably engaged with the sealing slot 205.

[0054] In practical implementation, when the double-arc gate 301 slides up and down, the auxiliary roller 306 rolls on both sides of the guide groove 203, and the auxiliary lifting slide 305 slides up and down. At the same time, the elasticity of the sealing spring 308 pushes the sealing strip 309 to tightly abut against the sealing groove 205 to ensure the sealing effect and avoid the reduction of sealing effect caused by sliding wear between the sealing strip 309 and the sealing groove 205. Meanwhile, the impact water flow dispersed to both sides by the arc surface of the double-arc gate 301 will flow into the space behind the elasticity release trend of the sealing spring 308 under the guidance of the water inlet groove 206, and release the water flow impact force along the direction of the release of the elasticity of the sealing spring 308, so as to avoid the sealing spring 308 retracting under the impact of the water flow and affecting the sealing performance.
