[0036] like Figure 1-Figure 13 As shown, the fast-opening lifting type hydraulic gate 100 according to the embodiment of the present invention includes a valve assembly 110 , a sealing assembly 120 and a driving assembly 130 .

[0037] The valve assembly 110 includes a valve body 111 and a valve plate 112. The valve body 111 has a Figure 1 The valve plate 112 is disposed in the first cavity and is movable relative to the valve body 111 in the up-down direction so that the valve assembly 110 can be opened or closed. A second cavity extending in the up-down direction is disposed between the valve body 111 and the valve plate 112. Specifically, as shown in FIG. Figure 1 and Figure 2As shown, the valve body 111 is a frame-type structure and extends in the up-down direction. The inner circumferential surface of the valve body 111 defines a first cavity and the first cavity is rectangular. The valve plate 112 is a rectangular plate and extends in the up-down direction. The valve plate 112 can move in the first cavity in the up-down direction. When the valve assembly 110 needs to be opened, the valve plate 112 moves upward. When the valve assembly 110 needs to be closed, the valve plate 112 moves downward to the lower end of the first cavity. A first sub-cavity along the up-down direction is provided on the valve body 111, and a second sub-cavity extending in the up-down direction is provided on the valve plate 112. The first sub-cavity and the second sub-cavity define a second cavity.

[0038] The sealing assembly 120 includes a first sealing member 121 and a second sealing member 122, both of which are disposed between the second cavity. The sealing assembly 120 has a first state and a second state. In the first state, at least one of the first sealing member 121 and the second sealing member 122 expands and the first sealing member 121 and the second sealing member 122 fit each other so as to block the second cavity. In the second state, at least one of the first sealing member 121 and the second sealing member 122 contracts and at least parts of the first sealing member 121 and the second sealing member 122 are separated from each other to define a third cavity 127. The third cavity 127 is suitable for passing liquid, and the liquid flows into between the first sealing member 121 and the second sealing member 122 so as to open the valve assembly 110. Specifically, as Figure 1-Figure 11 As shown, the first sealing member 121 and the second sealing member 122 can both be rubber sealing members. When the valve assembly 110 is closed, the sealing assembly 120 is in a first state, such as Figure 5 and Figure 6 As shown, at least one of the first seal 121 and the second seal 122 can expand, and the first seal 121 and the second seal 122 are tightly fitted in the second cavity, so that the first seal 121 and the second seal 122 seal the second cavity to prevent water from leaking from between the valve plate 112 and the valve. When the valve assembly 110 is opened, the sealing assembly 120 is in the second state, as shown in FIG. Fig.10 and Fig.11 As shown, at least one of the first seal 121 and the second seal 122 contracts, and the first seal 121 and the second seal 122 are separated, so that a third cavity 127 is formed between the first seal 121 and the second seal 122. Liquid (for example, water) can be introduced into the third cavity 127, and the liquid flows into between the first seal 121 and the second seal 122 through the third cavity 127, thereby lubricating the sealing assembly 120 and reducing the wear of the sealing assembly 120.

[0039] The driving assembly 130 is disposed in the valve assembly 110 and connected to the sealing assembly 120. The driving assembly 130 is used to drive the sealing assembly 120 to rotate relative to the valve assembly 110 in the up-down direction between the first position and the second position. In the first position, the sealing assembly 120 is in the first state, a portion of the first sealing member 121 and a portion of the second sealing member 122 are located in the valve body 111, and another portion of the first sealing member 121 and another portion of the second sealing member 122 are located in the valve plate 112. In the second position, the sealing assembly 120 is in the second state, one of the first sealing member 121 and the second sealing member 122 is located in the valve body 111, and the other of the first sealing member 121 and the second sealing member 122 is located in the valve plate 112. Specifically, as Figure 2-Figure 13 As shown, the drive assembly 130 is disposed on the valve plate 112 and is located behind the sealing assembly 120. The drive assembly 130 can be connected to the sealing assembly 120 so that the drive assembly 130 drives the sealing assembly 120 to rotate in the third chamber 127. In the first position, as shown in FIG. Figure 6 As shown, a portion of the first seal 121 and a portion of the second seal 122 are both located in the first sub-cavity, another portion of the first seal 121 and another portion of the second seal 122 are both located in the second sub-cavity, and the sealing assembly 120 is in the first state, so that the first seal 121 and the second seal 122 block the gap between the valve plate 112 and the valve body 111, thereby improving the sealing effect of the sealing assembly 120 and preventing water from flowing out from between the valve body 111 and the valve plate 112. In the second position, as shown in FIG. Fig.11 As shown, the first sealing member 121 is arranged in the first sub-cavity, and the second sealing member 122 is arranged in the second sub-cavity. When the valve assembly 110 is opened, the first sealing member 121 is located in the valve body 111, and the second sealing member 122 moves up and down with the valve plate 112. Since the sealing assembly 120 is in the second state, liquid is arranged between the first sealing member 121 and the second sealing member 122, thereby reducing the friction between the first sealing member 121 and the second sealing member 122, facilitating the separation of the first sealing member 121 and the second sealing member 122, and extending the service life of the first sealing member 121 and the second sealing member 122.

The second mounting portion 124 is provided with a third port 1241 and is connected to the first water outlet cavity 1215, so that the liquid in the third cavity 127 flows out of the third cavity 127 through the third port 1241, so that the first tube 140 and the second tube 150 are respectively connected to the first sealing cavity 1211 and the first water inlet cavity 1212 through the first mounting portion 123, so that the sealing assembly 120 is more reasonably arranged.

[0047] The third mounting portion 125 and the fourth mounting portion 126 are both arranged in the second cavity. The third mounting portion 125 and the fourth mounting portion 126 are respectively located at the upper and lower ends of the second sealing member 122 and connected to the upper and lower ends of the second sealing member 122. The third mounting portion 125 is provided with a fourth port 1251 and a fifth port 1252 penetrating the third mounting portion 125 in the up-down direction.

The fourth mounting portion 126 is provided with a sixth port 1261 penetrating the fourth mounting portion 126 in the up-down direction. The sixth port 1261 is communicated with the second water outlet cavity 1225. Specifically, as Figure 4 , Figure 8 and Fig. 9As shown, the third mounting portion 125 and the fourth mounting portion 126 are both made of hard rubber, the first mounting portion 123 and the third mounting portion 125 are symmetrically arranged, and the first mounting portion 123 and the third mounting portion 125 are buckled into a cylindrical shape, the second mounting portion 124 and the fourth mounting portion 126 are symmetrically arranged, and the second mounting portion 124 and the fourth mounting portion 126 are buckled into a cylindrical shape, the third mounting portion 125 and the fourth mounting portion 126 are respectively arranged at the upper and lower ends of the second sealing member 122, the third mounting portion 125 is provided with a fourth port 1251 and a fifth port 1252, and the fourth port 1251 and the fifth port 1252 are arranged in parallel at intervals, and the lower end of the fourth port 1251 is aligned with the second sealing member 122. The sealing cavity 1221 is connected, and the lower end of the fifth port 1252 is connected to the second water inlet cavity 1222. In the first state and the first sub-state, the first tube 140 is connected to the upper end of the fourth port 1251. In the second sub-state, the second tube 150 is connected to the fifth port 1252.

[0048] In some embodiments, the first mounting portion 123 is provided with a first connecting hole 1233, one end of the first connecting hole 1233 is connected to the first port 1231, and the third mounting portion 125 is provided with a second connecting hole 1253, one end of the second connecting hole 1253 is connected to the fourth port 1251. In the first state or the first sub-state, the first connecting hole 1233 and the second connecting hole 1253 are connected. Specifically, as Figure 4 and Figure 8 As shown, the first connecting hole 1233 and the second connecting hole 1253 are respectively arranged in the first mounting part 123 and the second mounting part 124. In the first state and the first sub-state, the first port 1231 and the fourth port 1251 are connected through the first connecting hole 1233 and the second connecting hole 1253 respectively, so that when one of the first port 1231 and the fourth port 1251 is inflated, the first seal 121 and the second seal 122 can be expanded at the same time, or when one of the first port 1231 and the fourth port 1251 is deflating, the first seal 121 and the second seal 122 can be contracted at the same time.

[0049] It can be understood that a connecting valve can be set between the first connecting hole 1233 and the second connecting hole 1253. In the first state, since the first sealing member 121 and the second sealing member 122 fit each other, the first connecting hole 1233 and the second connecting hole 1253 are relatively arranged and connected through the connecting valve. In the second sub-state, since the first sealing member 121 and the second sealing member 122 are separated, the first connecting hole 1233 and the second connecting hole 1253 are disconnected.

[0050] In some embodiments, the fast-opening lifting water gate 100 further includes a pump 160, which is disposed on the valve body 111. In a first state, the pump 160 is communicated with the first tube 140 to inflate at least one of the first seal 121 and the second seal 122 to expand at least one of the first seal 121 and the second seal 122. In a first sub-state, the pump 160 is communicated with the first tube 140 to evacuate at least one of the first seal 121 and the second seal 122 to shrink at least one of the first seal 121 and the second seal 122. In a second sub-state, the pump 160 is communicated with the second tube 150 to pass liquid into the third chamber 127. Specifically, as Figure 1 and Figure 2 As shown, the pump 160 is arranged at the upper end of the valve body 111, and the pump 160 is connected with the first tube 140 and the second tube 150 through a connecting tube, and a first connecting valve is provided between the connecting tube and the first tube 140, and a second connecting valve is provided between the connecting tube (not shown in the figure) and the second tube 150. In the first state, the first connecting valve is opened and the second connecting valve is closed, and the pump 160 can inflate the first tube 140, so that at least one of the first sealing member 121 and the second sealing member 122 expands. In the first sub-state, the first connecting valve is opened and the second connecting valve is closed, and the pump 160 can evacuate the first tube 140, so that at least one of the first sealing member 121 and the second sealing member 122 shrinks. In the second sub-state, the first connecting valve is closed, the second connecting valve is opened, and the pump 160 is connected with the second tube 150, so as to allow liquid to enter the third chamber 127.

[0051] In some embodiments, the drive assembly 130 includes a motor 131 and a drive shaft 132 .

[0052] The motor 131 is disposed at the upper end of the valve plate 112, and the drive shaft 132 is disposed in the valve plate 112 and adjacent to one side of the sealing assembly 120. The drive shaft 132 is connected to the motor 131 so that the motor 131 drives the drive shaft 132 to rotate in the up and down directions relative to the valve body 111. The upper and lower ends of the drive shaft 132 cooperate with the upper and lower ends of the sealing assembly 120 so that the drive shaft 132 drives the sealing assembly 120 to rotate between the first position and the second position. Specifically, Figure 7 and Fig.14As shown, the motor 131 is arranged on the valve plate 112 and adjacent to the sealing assembly 120, the driving shaft 132 is a rotating shaft and extends in the up-down direction, the motor 131 is connected to the upper end of the driving shaft 132, so that the motor 131 drives the driving shaft 132 to rotate around the up-down direction, the upper end of the driving shaft 132 is provided with a first gear, the outer ends of the first mounting portion 123 and the third mounting portion 125 are provided with a second gear meshed with the first gear, the lower end of the driving shaft 132 is provided with a third gear, the outer ends of the second mounting portion 124 and the fourth mounting portion 126 are provided with a fourth gear meshed with the third gear, thereby, the sealing assembly 120 is driven to rotate between the first position and the second position through the driving shaft 132, and the upper and lower ends of the sealing assembly 120 are prevented from twisting during the rotation of the sealing assembly 120, thereby ensuring the rotation efficiency of the sealing assembly 120.

[0053] It is worth noting that the driving assembly 120 drives the first seal 121 and the second seal 122 to rotate synchronously, and in the single opening and closing process of the gate assembly 110, the first seal 121 and the second seal 122 are displaced 180° (in other words: the first seal and the second seal always rotate in a fixed direction), ensuring uniform wear of the outer peripheral surfaces of the first seal 121 and the second seal 122, preventing excessive wear of the first seal 121 and the second seal 122, and causing failure of the sealing assembly 120.

[0054] In some embodiments, the first sealing member 121 includes a first skeleton 1213 and a first sealing sleeve 1214, the first skeleton 1213 is disposed in the first sealing sleeve 1214, and the first sealing sleeve 1214 has elastic deformation capability, so that in a first state, the first sealing sleeve 1214 expands, and in a second state, the first sealing sleeve 1214 contracts, and / or, the second sealing member 122 includes a second skeleton 1223 and a second sealing sleeve 1224, the second skeleton 1223 is disposed in the second sealing sleeve 1224, and the second sealing sleeve 1224 has elastic deformation capability, so that in a first state, the second sealing sleeve 1224 expands, and in a second state, the second sealing sleeve 1224 contracts. Specifically, as Figure 6As shown, the first skeleton 1213 is arranged in the first sealing sleeve 1214, the first sealing cavity 1211 is formed in the first sealing sleeve 1214, the first skeleton 1213 is a hard material, the first sealing sleeve 1214 is a rubber material that can be elastically deformed, the second skeleton 1223 is arranged in the second sealing sleeve 1224, the second sealing cavity 1221 is formed in the second sealing sleeve 1224, the second skeleton 1223 is a hard material, the second sealing sleeve 1224 is a rubber material that can be elastically deformed, thus, the first skeleton 1213 and the second skeleton 1223 provide a support basis for the first sealing member 121 and the second sealing member 122, ensuring that the first The sealing sleeve 1214 and the second sealing sleeve 1224 maintain stable shapes during the expansion and contraction process. In addition, the structural design of the first skeleton 1213 and the second skeleton 1223 ensures that the first sealing sleeve 1214 and the second sealing sleeve 1224 can deform evenly during the expansion and contraction process, avoiding local stress concentration and reducing the risk of damage to the first sealing sleeve 1214 and the second sealing sleeve 1224. Secondly, the existence of the first skeleton 1213 and the second skeleton 1223 enables the first sealing sleeve 1214 and the second sealing sleeve 1224 to respond quickly during inflation or deflating and quickly reach an expanded or contracted state, thereby reducing the response speed of the sealing assembly 120.

[0055] In some embodiments, in a projection plane orthogonal to the up-down direction, the first frame 1213 and the second frame 1223 are both arc-shaped, and the first frame 1213 and the second frame 1223 are symmetrically arranged. In the first state, the first frame 1213 and the second frame 1223 are buckled into a cylindrical shape. Specifically, Figure 6 As shown, the cross-section of the first skeleton 1213 and the cross-section of the second skeleton 1223 are both arc-shaped, and the first skeleton 1213 and the second skeleton 1223 can be buckled into a cylindrical shape, thereby making the first seal 121 and the second seal 122 arc-shaped, ensuring that the first seal 121 and the second seal 122 can rotate smoothly in the second cavity, and the arc-shaped setting allows the first seal 121 and the second seal 122 to smoothly transition during expansion and contraction, thereby reducing the wear of the first seal 121 and the second seal 122.

[0056] In some embodiments, the sealing assembly 120 further includes a third state, in which liquid is introduced into the top of the third chamber 127 and discharged from the bottom of the third chamber 127, so as to clean the sealing assembly 120. Thus, when the valve assembly 110 is rotated from the open state to the closed state, the sealing assembly 120 can be placed in the third state, the pump 160 is connected to the second pipe 150, so that liquid is introduced into the third chamber 127, and the third port 1241 and the sixth port 1261 are respectively connected to the first water outlet chamber 1215 and the second water outlet chamber 1225, so that liquid is discharged from the third port 1241 and the sixth port 1261, so as to clean the sealing assembly 120, wash away the mud and sand in the sealing assembly 120, and ensure the sealing performance and service life of the sealing assembly 120.

[0057] In some embodiments, Figure 1 and Figure 2 As shown, the fast-opening lifting hydraulic gate 100 also includes a driving motor 180 and a connecting rod 170. The driving motor 180 is arranged at the upper end of the valve body 111, and the two ends of the connecting rod 170 are respectively connected to the valve plate 112 and the driving motor 180, so that the connecting rod 170 is driven up and down by the driving motor 180, and the connecting rod 170 drives the valve plate 112 to move up and down, so that the valve assembly 110 is opened or closed.

[0058] The working process of the fast-opening lifting hydraulic gate 100 of the embodiment of the present invention is as follows:

[0059] The quick-opening lifting hydraulic gate 100 is initially located at the first position and in the first state. When the valve assembly 110 is opened, the motor 131 drives the drive shaft 132 to rotate, and the drive shaft 132 drives the sealing assembly 120 to rotate from the first position to the second position. At this time, the first tube 140 is connected to the first port 1231, the first connecting hole 1233 and the second connecting hole 1253 are connected, and the second tube 150 is connected to the second port 1232. The gas in the first sealing member 121 and the second sealing member 122 is pumped out by the pump 160, so that the first sealing member 121 and the second sealing member 122 shrink, and the third port 1241 and the sixth port 1261 are closed by the valve. The pump 160 adds water to the second tube 150 so that the water in the second tube 150 flows into the first water inlet chamber 1212 through the second port 1232, and then flows through the water inlet chamber 1212. Flows into the third chamber 127. Since the third port 1241 and the sixth port 1261 are closed, water can only pass through the gap between the first seal 121 and the second seal 122 to form liquid lubrication between the first seal 121 and the second seal 122. The valve assembly 110 is opened, and one of the first seal 121 and the second seal 122 moves upward with the valve plate 112, and the other of the first seal 121 and the second seal 122 remains in the valve body 111. Due to the effect of liquid lubrication, the wear of the first seal 121 and the second seal 122 during the process of opening the gate plate can be reduced, thereby extending the service life of the first seal 121 and the second seal 122.

[0060] When the valve assembly 110 is closed, the valve plate 112 is moved downward, so that the first sealing member 121 and the second sealing member 122 are buckled into a whole again, and the motor 131 drives the driving shaft 132 to rotate (the driving shaft 132 always rotates in one direction to make the sealing assembly 120 wear evenly), and the sealing assembly 120 rotates from the second position to the first position. At this time, the first tube 140 is connected to the fourth port 1251, the first connecting hole 1233 and the second connecting hole 1253 are connected, and the second tube 150 is connected to the fifth port 1252, and the third port 1241 is connected to the sixth port 1252. The valve in the port 1261 is opened, and liquid is introduced into the second tube 150 through the pump 160, so that the liquid flows into the second water inlet chamber 1222, and then flows into the third chamber 127 through the water inlet chamber, and flows out through the third port 1241 and the sixth port 1261, so as to clean the first sealing member 121 and the second sealing member 122. After cleaning, the fourth port 1251 is inflated through the pump 160, and the gas expands the first sealing member 121 and the second sealing member 122 through the first connecting hole 1233 and the second connecting hole 1253, so that the sealing assembly 120 plays a sealing role.

[0061] The technical features of the above embodiments may 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 pointed out that, for those of ordinary skill in the art, several modifications and improvements may be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
