Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic gates, and in particular to a double-layer sealed hydraulic gate structure. Background Art

[0002] Hydraulic gates are control facilities used to close and open discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge silt and floating objects, etc. In water conservancy projects, hydraulic gates are often needed to control the water storage capacity of rivers, canals and reservoirs.

[0003] However, most of the current water conservancy gates are sealed in the form of single-layer sealing. For example, a "P"-shaped sealing strip is set between the gate and the gate track. Although it can achieve a sealing and water-stopping effect, the sealing reliability is still general, resulting in water seepage and leakage after a period of use. In addition, since the near-water surface of the gate is often impacted by the water flow and produces a certain amount of vibration, as the vibration time becomes longer and longer, it is not only easy to cause repeated squeezing of the sealing strip, but also damage to other components in the gate, which is bound to affect the service life of the corresponding components.

[0015] Compared with the prior art, the present invention provides a double-layer sealed hydraulic gate structure, which has the following beneficial effects.

[0016] 1. The present invention, through the setting of the blocking net, will not affect the normal passage of water when the gate is opened, and in the process of closing the gate, the blocking net can filter the water flowing between the gate and the bottom sill to a certain extent, preventing larger impurities from passing through and getting stuck between the gate and the bottom sill, thereby ensuring the smooth closing of the gate and preventing larger impurities from damaging the bottom of the first airbag sealing strip.

[0017] 2. The present invention, through the setting of the spraying and impurity removal mechanism, when the gate is closed, multiple one-way nozzles can spray airflow at high speed between the bottom sill and the gate, thereby blowing out impurities between the bottom sill and the gate, preventing impurities from being stuck between the first airbag sealing strip and the sealing groove after sealing, and further avoiding damage to the first airbag sealing strip caused by impurities, thereby improving the protection capability of the first airbag sealing strip.

[0018] 3. The present invention, through the setting of the double-layer airbag sealing mechanism, can achieve double-layer sealing between the two sides of the gate and the gate groove and between the bottom of the gate and the bottom sill, thereby improving the sealing and water-stopping ability of the gate structure, and can effectively prevent water leakage and seepage. In addition, through the cooperation between the gate and the support frame, the bottom sealing assembly and the bottom sill and the first airbag sealing strip will be sealed more tightly, thereby further improving the sealing performance there.

[0019] 4. The present invention, through the setting of the inflation mechanism, can make the first airbag sealing strip and the second airbag sealing strip undergo a certain expansion deformation during the process of closing the gate, thereby effectively improving the sealing between the gate and the gate groove, ensuring reliable sealing and water stopping of the water flow, and through this setting, when the gate is lifted and slid, since the first airbag sealing strip and the second airbag sealing strip are in a normal contracted state, they do not contact the gate groove, and therefore, the first airbag sealing strip and the second airbag sealing strip will not be caused friction damage during the lifting and sliding process, which can improve the service life of the sealing component to a certain extent.

[0020] 5. The present invention can lock the gate and the gate track by setting the opening and closing limit mechanism, and the whole locking process is carried out automatically without the need for additional operation by the operator. At the same time, the whole locking process is realized by the opening and closing device and the hanger, so there is no need to provide an additional driving device, thereby improving the degree of locking automation while not requiring excessive energy.

[0021] 6. The present invention, through the setting of the clamping mechanism, can make the gate tightly pressed against the other side wall of the gate groove through the supporting wheel, thereby improving the connection stability between the gate and the gate track, and can effectively reduce the vibration caused by the gate being washed and hit by water flow or other things, thereby effectively preventing the damage of related components caused by vibration, improving its protection ability, and ensuring the service life of related components.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Reference Figure 1-2 A double-layer sealed hydraulic gate structure includes a gate track 10, a gate 20, a sill 100, an opening and closing device 120, and a gate groove 101 opened inside the gate track 10. The gate track 10 is two symmetrically distributed and fixedly installed on the sill 100, and the two sides of the gate 20 are respectively slidably connected in the gate groove 101. The opening and closing device 120 is installed on the top of the gate track 10, and is used to drive the gate 20 to slide upward or downward along the gate groove 101, so as to realize the opening and closing of the gate structure. The opening and closing device 120 adopts a screw-type opening and closing machine.

[0043] Reference Figure 3-7 The water surface of the gate 20 is slidably connected with a blocking net 30, and both sides of the blocking net 30 are also located in the gate groove 101. The outer periphery of the gate 20 and the back water surface and the lower part of the blocking net 30 are provided with a double-layer airbag sealing mechanism 50, which is used to seal between the gate 20 and the gate groove 101 and between the gate 20 and the bottom sill 100. The blocking net 30 and the gate 20 are provided with a spraying and removing impurities mechanism 40, which is used to spray impurities on the bottom sill 100 when the gate 20 is closed. The sealing surface is sprayed to remove impurities, and an inflation mechanism 60 connected to the opening and closing device 120 is provided in the gate 20 for inflating the double-layer airbag sealing mechanism 50. Both sides of the barrier net 30 are provided with a clamping mechanism 80 connected to the opening and closing device 120 for tightly supporting between the near-water surface of the gate 20 and the side wall of the gate groove 101, and an opening and closing limit mechanism 70 is also provided in the gate 20 for fixing the gate 20 to the gate track 10.

[0044] Reference Figure 7-10 The blowing and impurity removal mechanism 40 includes a support frame 401 fixed to the lower part of the blocking net 30 and a second air cylinder assembly 90 arranged in the gate 20. A blowing pipe 404 is fixed inside the support frame 401. An air guide pipe 403 is connected between the blowing pipe 404 and the second air cylinder assembly 90, and a one-way nozzle 402 facing the bottom of the gate 20 is fixed on the outside of the blowing pipe 404. The gas entering the blowing pipe 404 from the air guide pipe 403 can be sprayed outward onto the bottom sill 100 through the one-way nozzle 402.

[0045] The second inflator assembly 90 includes a second cylinder 91 and a second piston 92 slidably mounted inside the second cylinder 91. The second cylinder 91 is connected to the blowing pipe 404 through the air pipe 403, and a one-way valve 94 is fixedly mounted on the outside of the second cylinder 91. External gas can enter the second cylinder 91 through the one-way valve 94. The outside of the second piston 92 is fixedly connected to a second piston rod 93. A connecting frame 31 is connected between the outer end of the second piston rod 93 and the blocking net 30. The connecting frame 31 is slidably mounted on the gate 20. The interior of the connecting frame 31 is hollow. The air pipe 403 is arranged in the connecting frame 31 to prevent the air pipe 403 from leaking out, which can provide a good protective effect on the air pipe 403. Figure 2 The outer surface of the gate 20 is fixedly connected with a guide sleeve 140 sleeved on the outside of the connecting frame 31 to ensure the stability of the relative sliding of the connecting frame 31 on the gate 20.

[0046] When the gate structure is in the open state, the lower surface of the blocking net 30 is lower than the lower surface of the gate 20. When the gate 20 is moved downward to close, the lower surface of the blocking net 30 will first contact the bottom sill 100, and then the gate 20 will continue to move downward. During this process, the gate 20 and the blocking net 30 can slide relative to each other, and under the action of the connecting frame 31 and the second piston rod 93, the second piston 92 and the second cylinder 91 can slide relative to each other, so that the gas in the second cylinder 91 is sprayed outwardly through the one-way nozzle 402 to between the bottom sill 100 and the gate 20, and then the impurities between the bottom sill 100 and the gate 20 are blown out.

[0047] Reference Figure 3 , Fig.11 and Fig.12 The double-layer airbag sealing mechanism 50 includes a first airbag sealing strip 51, a second airbag sealing strip 52 and a bottom sealing assembly 53. The first airbag sealing strip 51 is U-shaped and is sleeved and fixed on the two side surfaces and the bottom surface of the gate 20. The second airbag sealing strip 52 is fixed on both sides of the back water surface of the gate 20. The cooperation between the vertical sections on both sides of the U-shaped first airbag sealing strip 51 and the second airbag sealing strip 52 can realize a double-layer seal between the two sides of the gate 20 and the gate groove 101. The bottom sealing assembly 53 is fixed to the outside of the support frame 401 in the horizontal direction. The horizontal section of the first airbag sealing strip 51 and the bottom sealing assembly 53 can realize a double-layer seal between the bottom of the gate 20 and the bottom sill 100, thereby improving the sealing performance of the gate structure.

[0048] Reference Fig.11 The inflation mechanism 60 includes a first inflation cylinder assembly 61 and an inflation tube group 62. The first inflation cylinder assembly 61 includes a first cylinder body 6101 and a first piston 6102 slidably installed in the first cylinder body 6101. The first cylinder body 6101 is connected to the interior of the first airbag sealing strip 51 and the second airbag sealing strip 52 respectively through the inflation tube group 62. A first piston rod 6103 is fixedly installed on the outside of the first piston 6102.

[0049] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A hanger 121 is connected between the opening and closing device 120 and the gate 20. The hanger 121 is slidably connected inside the gate 20 and is connected to the first piston rod 6103. A limiting member 122 is fixed on the hanger 121 to limit the relative sliding between the hanger 121 and the gate 20 and ensure that the gate 20 is stably suspended on the hanger 121.

[0050] During the process of the gate 20 sliding downward and closing, after the gate 20 contacts the sill 100, the gate 20 stops sliding, and the hanger 121 continues to slide downward under the drive of the opening and closing device 120, so that the hanger 121 pushes the first piston 6102 downward to slide downward in the first cylinder 6101, thereby inflating the first airbag sealing strip 51 and the second airbag sealing strip 52, thereby improving the sealing and water-stopping capabilities.

[0051] Reference Figure 3 , Figure 7 as well as Figures 13 to 17 The clamping mechanism 80 includes two brackets 81 and two pressure rods 82. The two brackets 81 are respectively fixed to the two sides of the barrier net 30, and the brackets 81 are located between the near water surface of the gate 20 and the side wall of the gate slot 101. The insides of the two brackets 81 are provided with extrusion components 83 for extruding the side wall of the gate slot 101. One end of the two pressure rods 82 is respectively inserted and slid in the two brackets 81 to drive the extrusion components 83. The other ends of the two pressure rods 82 are inserted and slid in the gate 20, and the part of the pressure rod 82 inserted into the gate 20 is fixedly connected with two limit protrusions 8201. The two limit protrusions 820 A certain gap is left in the vertical direction, and an extrusion protrusion 123 is fixed between the two limiting protrusions 8201 on the outer side of the hanger 121, and the extrusion protrusion 123 is sleeved and slid on the pressure rod 82. When the hanger 121 slides down in the gate 20, the extrusion protrusion 123 can press the limiting protrusion 8201 at the lower part downward, and push the pressure rod 82 to slide downward for a certain distance to provide downward pressure to the extrusion assembly 83. When the hanger 121 slides up in the gate 20, the extrusion protrusion 123 can push the upper limiting protrusion 8201 upward, thereby driving the pressure rod 82 to reset upward.

[0052] The extrusion assembly 83 includes a vertical slide bar 8301, a horizontal slide bar 8302 and an extrusion piece 8303. The vertical slide bar 8301 is connected to the bracket 81 in a vertical sliding manner and the upper end is fixed to the pressure rod 82. The horizontal slide bar 8302 is parallel to the vertical slide bar 8301 and is connected to the bracket 81 in a horizontal sliding manner. There are several extrusion pieces 8303 and they are evenly fixed on the horizontal slide bar 8302 in the vertical direction. The side wall of the bracket 81 is provided with a through hole connected to the inside thereof. The extrusion piece 8303 can contact the side wall of the gate slot 101 through the through hole. The first wedge block 8304 is fixed at the position corresponding to the horizontal slide bar 8302 and the vertical slide bar 8301. A second wedge block 8305 is fixed at a position corresponding to the vertical slide bar 8301 and the horizontal slide bar 8302, the first wedge block 8304 corresponds to the inclined surface of the second wedge block 8305, and the first wedge block 8304 is located below the second wedge block 8305. Therefore, when the vertical slide bar 8301 slides downward due to the downward pressure from the pressure rod 82, the inclined surface of the first wedge block 8304 can be squeezed by the inclined surface of the second wedge block 8305, thereby pushing the horizontal slide bar 8302 and the extrusion piece 8303 to slide horizontally, and in order to ensure the uniformity of the force on the horizontal slide bar 8302, the first wedge block 8304 and the second wedge block 8305 can be set into multiple groups.

[0053] Reference Figure 4-6 The opening and closing limit mechanism 70 includes a slider 71, a latch 73, and a limit groove 74 opened on the gate track 10 and adapted to the latch 73. The slider 71 slides vertically inside the gate 20, and the latch 73 slides horizontally inside the gate 20. A connecting rod 72 is connected between the slider 71 and the latch 73. Pressure blocks 75 are fixed to the outside of the hanger 121 above and below the slider 71. In order to ensure the stability of the connection between the gate 20 and the gate track 10, the opening and closing limit mechanism 70 can be set into two groups, which are symmetrically distributed on both sides of the gate 20.

[0054] Reference Figure 1 , Fig.13 and Fig.14 A sealing groove 1001 is provided on the upper surface of the bottom sill 100 below the gate 20, and the support frame 401 and the bottom sealing assembly 53 are inserted into the sealing groove 1001. A second inclined surface 1002 is provided on the side of the sealing groove 1001 close to the support frame 401, and a first inclined surface 4012 corresponding to the second inclined surface 1002 is provided at the lower part of the support frame 401.

[0055] The bottom sealing assembly 53 includes a third airbag sealing strip 5301, a connecting tube 5302 and a fourth airbag sealing strip 5303. The third airbag sealing strip 5301 is fixed on the first inclined surface 4012, the fourth airbag sealing strip 5303 is fixed on the side of the support frame 401 close to the first airbag sealing strip 51, and the interior of the third airbag sealing strip 5301 is connected to the interior of the fourth airbag sealing strip 5303 through the connecting tube 5302.

[0056] A boss 4011 is provided on the side of the support frame 401 close to the first airbag sealing strip 51. The boss 4011 is located below the gate 20. When the gate 20 is closed, the lower part of the gate 20 will be pressed tightly against the boss 4011, thereby tightly inserting the support frame 401 into the sealing groove 1001, thereby further improving the sealing performance there.

[0057] Reference Fig.12 Support wheels 150 are rotatably mounted on both sides of the gate 20 . The support wheels 150 extend outward to the back surface of the gate 20 and contact the inner wall of the gate groove 101 to reduce the friction of the gate 20 sliding in the gate groove 101 .

[0058] In the present invention, Figure 1 As shown, when the gate structure is in the open state, the lower surface of the blocking net 30 is lower than the lower surface of the gate 20. When the gate 20 is closed, the opening and closing device 120 drives the hanger 121 to move downward, and the gate 20 moves downward synchronously under the action of gravity, and then the lower surface of the blocking net 30 will first contact the sill 100 and stop moving downward, and then the gate 20 continues to move downward. During this process, the blocking net 30 can filter the water flow passing through the gate 20 and the sill 100 to prevent larger impurities from passing through and getting stuck between the gate 20 and the sill 100, thereby ensuring the smooth closing of the gate 20 and preventing larger impurities from damaging the bottom of the first airbag sealing strip 51.

[0059] Moreover, after the blocking net 30 stops moving downward, the hanger 121 and the gate 20 continue to move downward. During this process, the gate 20 and the blocking net 30 will slide relative to each other, and therefore the gate 20 will slide downward on the connecting frame 31 and the pressure rod 82, and thereby drive the pressure rod 82 to slide downward on the second piston 92, so as to fill the air guide pipe 403 with air. After the air flowing into the air guide pipe 403 enters the blowing pipe 404, it will be directly sprayed outward at high speed to between the bottom sill 100 and the gate 20 through multiple one-way nozzles 402, thereby blowing out impurities between the bottom sill 100 and the gate 20, preventing impurities from being stuck between the first airbag sealing strip 51 and the sealing groove 1001 after sealing, and further avoiding impurities from damaging the first airbag sealing strip 51, thereby improving the protection capability of the first airbag sealing strip 51.

[0060] When the first airbag sealing strip 51 moves down into the sealing groove 1001, the gate 20 and the first cylinder 6101 stop moving down, and the hanger 121 will still move down a certain distance driven by the opening and closing device 120. In this process, the hanger 121 can push the first piston 6102 downward to slide in the first cylinder 6101 through the first piston rod 6103, and thereby fill the first airbag sealing strip 51 and the second airbag sealing strip 52 with air through the inflation tube group 62, and cause them to expand and deform to a certain extent, so that the first airbag sealing strip 51 is closely attached to the inner surface of the gate groove 101 and the bottom wall of the sealing groove 1001, and the second airbag sealing strip 52 is also closely attached to the inner surface of the gate groove 101, thereby effectively improving the sealing between the gate 20 and the gate groove 101, and ensuring reliable sealing of the water flow.

[0061] Moreover, after the lower portion of the support frame 401 is inserted into the sealing groove 1001, as the gate 20 moves downward, the boss 4011 will be squeezed downward through its lower portion, and the downward pressure will cause the third airbag sealing strip 5301 to accumulate in the second inclined surface 1002. After the third airbag sealing strip 5301 is squeezed by the second inclined surface 1002, a part of the air inside it will enter the fourth airbag sealing strip 5303 through the connecting tube 5302, so that the fourth airbag sealing strip 5303 will undergo a certain expansion deformation and be tightly pressed against the outer surface of the first airbag sealing strip 51, the lower surface of the gate 20 and the bottom wall of the sealing groove 1001, thereby further improving the sealing performance there. The first airbag sealing strip 51, the second airbag sealing strip 52, the third airbag sealing strip 5301 and the fourth airbag sealing strip 5303 can realize double-layer sealing between the gate 20 and the gate track 10 and between the gate 20 and the sealing groove 1001, which can effectively ensure the reliable sealing of the entire gate structure.

[0062] As the opening and closing device 120 drives the hanger 121 to move downward, the limiting member 122 will eventually press on the crossbeam inside the gate 20, thereby restricting and fixing the gate 20 to a certain extent. Figure 5 As shown. Moreover, when the hanger 121 slides on the gate 20, the pressure block 75 located at the upper part will also push the slider 71 downward to slide, and the slider 71 will then push the latch 73 to slide outward through the connecting rod 72. The outer end of the latch 73 extends outward from the gate 20 and is inserted into the limit groove 74 on the gate track 10, thereby locking the gate 20 and the gate track 10 and completing the closing of the gate 20. The entire locking process is automatic and does not require additional manipulation by the operator. At the same time, the entire locking process is realized by the opening and closing device 120 and the hanger 121, so there is no need to provide an additional driving device. In order to ensure the seal between the latch 73 and the gate 20, a sliding sealing ring can be installed between the two.

[0063] When the hanger 121 slides on the gate 20, the extrusion protrusion 123 on the outer side of the hanger 121 can press the limit protrusion 8201 located at the lower part downward, and push the pressure rod 82 to slide downward for a certain distance to push the vertical slide bar 8301 to slide synchronously. In this process, the second wedge block 8305 slides synchronously with the vertical slide bar 8301 and presses the inclined surface of the first wedge block 8304 downward through the inclined surface of the second wedge block 8305, thereby pushing the horizontal slide bar 8302 and the extrusion piece 8303 to slide horizontally, thereby pushing the extrusion piece 8303 to slide horizontally. 03 extends outward and presses tightly against the side wall of the gate groove 101. At this time, the side wall of the gate groove 101 provides a reverse thrust to the bracket 81, so that the bracket 81 is pressed tightly against the gate 20. As a result, the gate 20 is pressed tightly against the other side wall of the gate groove 101 through the support wheel 150, thereby improving the connection stability between the gate 20 and the gate track 10, and effectively reducing the vibration caused by the gate 20 being washed and hit by water or other things, thereby effectively preventing the damage of related components caused by vibration, improving its protection capability, and ensuring the service life of related components.

[0064] Furthermore, by pressing down the boss 4011 on the support frame 401 through the bottom of the gate 20, the first inclined surface 4012 will be subjected to a reaction force from the second inclined surface 1002. Through this reaction force, the support frame 401 will also be pressed tightly against the lower part of the gate 20, thereby improving the stability of the connection between the lower part of the gate 20 and the bottom sill 100, and further reducing the vibration generated when the gate 20 is impacted.

[0065] When the gate 20 is in a closed state and needs to be opened, the hanger 121 is pulled upward by the opening and closing device 120. At this time, the hanger 121 first slides upward for a certain distance in the gate 20 while the gate 20 remains stationary. Figure 6 As shown, the hanger 121 can push the slider 71 upward to slide through the pressure block 75 located at the bottom, and the slider 71 can then pull the pin 73 out of the limit groove 74 through the connecting rod 72 and retract it back into the gate 20, thereby automatically releasing the lock between the gate 20 and the gate track 10.

[0066] During the upward sliding of the hanger 121 in the gate 20, the extrusion protrusion 123 on the hanger 121 separates from the lower limiting protrusion 8201 and then contacts the upper limiting protrusion 8201, and drives the pressure rod 82 to slide upward a certain distance in the gate 20 and reset by pushing the upper limiting protrusion 8201. At this time, the vertical sliding rod 8301 slides up synchronously with the pressure rod 82, thereby canceling the extrusion pressure of the extrusion piece 8303 on the inner wall of the gate groove 101, and thereby releasing the tight pressure of the gate 20 on the gate groove 101.

[0067] As the hanger 121 slides upward inside the gate 20, the limit piece 122 that slides upward with the hanger 121 will also come into contact with the upper crossbeam inside the gate 20, and then the opening and closing device 120 can pull the hanger 121 upward to continue to pull the gate 20 upward through the limit piece 122 to slide. During this process, the blocking net 30 will not slide until the top of the connecting frame 31 contacts the upper surface of the gate 20, and then it will drive the blocking net 30 to move upward synchronously and complete the opening process of the gate 20.
