[0002] Pneumatic shield gates have significant advantages in terms of control flexibility, structural and design advantages, operation and maintenance, environmental protection and safety, economy and practicality. They are a type of water conservancy engineering equipment with excellent comprehensive performance. The water level can be continuously adjusted, the water flow is slowly accelerated, and it is not easy to produce cavitation, scour and vortex. In addition, in the event of a power outage caused by a flood, the water level can still be controlled by discharging the air in the air bag to safely discharge the flood. The air bag material is made of food hygiene grade material to ensure water quality safety. However, after long-term use, the air bag material ages and its elasticity decreases, which may cause the air bag to leak. For this reason, some patents have published air bag maintenance methods.

[0003] For example, the patent with authorization announcement number CN220908318U discloses an air shield dam that automatically adjusts based on water level changes. By pressing the control lever, the push plate pushes the reset spring and rotates the connecting rod. The rotation of the connecting rod drives the card plate out of the inner wall of the card slot, so that the airbag can be taken out for inspection and maintenance to ensure the normal operation of the device. However, there is still room for improvement.

[0004] The common shortcoming of the air bag maintenance of the partially activated shield gate in the above patent and the prior art is that the gate loses its support due to the removal of the air bag, and the gate cannot work normally at this time, so the air bag needs to be repaired and replaced when there is no water, which has low applicability. Utility Model Content

[0005] In response to the above problems, the present application provides an enhanced pneumatic shield gate to solve the problem of low applicability of the above patent that when the air bag is repaired, the gate loses its support due to the removal of the air bag, and the gate cannot work normally. Therefore, the air bag needs to be repaired and replaced when there is no water.

[0006] An enhanced pneumatic shield gate comprises a mounting plate, a gate is hinged on the top of the mounting plate, an air bag is installed between the gate and the mounting plate, two connecting rods are symmetrically hinged on the outer side of the gate, a connecting block is fixedly installed on one end of the connecting rod away from the gate, and the connecting block is connected to the mounting plate by bolts;

[0007] A mounting base is fixedly installed at the bottom of the airbag, two fixing blocks are symmetrically fixedly installed at the bottom of the mounting base, a plug column is installed in the middle of the fixing block, and the plug column is connected with the bolt through a linkage mechanism.

[0008] Specifically, a plug-in hole is provided through the middle of the fixing block, and the plug-in post is slidably plugged into the plug-in hole.

[0009] Specifically, a slide groove is provided on the top of the mounting plate, and the connecting block is slidably engaged in the slide groove.

[0010] Specifically, a bolt hole is formed through the top of the connection block, a fixing hole matching with the bolt hole is formed on the top of the mounting plate, and the bolt matches with the bolt hole.

[0011] Specifically, the linkage mechanism includes a linkage column, which is slidably installed inside the fixing hole, a rope is slidably installed through the middle of the linkage column, and a yield groove matching the rope is opened on the outer side of the linkage column.

[0012] Specifically, one end of the rope is fixedly mounted on the inner side of the mounting plate, and the other end is fixedly mounted on the end of the plug post. A spring is fixedly mounted between the end of the plug post and the inner side of the mounting plate, and the spring is movably sleeved on the outer periphery of the rope.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model discloses an enhanced pneumatic shield gate. When the air bag needs to be removed for maintenance or replaced, the staff will inflate the air bag to the maximum, and then screw the bolts into the bolt holes and the fixing holes to fix the gate, ensuring that the gate can intercept water normally when the air bag is replaced.

[0015] During the downward movement of the bolt, the restriction of the fixed block is released through the transmission mechanism. The staff can remove the old mounting plate and air bag, replace them with new mounting plate and air bag, and then rotate to remove the bolt. Under the elastic force of the spring, the column is inserted into the socket hole to fix the gate while removing the air bag. It is simple and convenient, and improves the efficiency of air bag replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0025] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides an enhanced pneumatic shield gate, including a mounting plate 2, a gate 1 is hinged on the top of the mounting plate 2, and is used to control the water level. An air bag 3 is installed between the gate 1 and the mounting plate 2. The inflation and degassing of the air bag 3 belong to the prior art and will not be described in detail herein. The air bag 3 is used to adjust the inclination angle of the gate 1. Two connecting rods 4 are symmetrically hinged on the outer side of the gate 1. A connecting block 13 is fixedly installed on one end of the connecting rod 4 away from the gate 1, and the connecting block 13 is connected to the mounting plate 2 by bolts;

[0026] A mounting base 5 is fixedly installed at the bottom of the airbag 3, and two fixing blocks 6 are symmetrically fixedly installed at the bottom of the mounting base 5. A plug post 8 is installed in the middle of the fixing block 6 for stabilizing the airbag 3. The plug post 8 is connected to the bolt through a linkage mechanism.

[0027] Specifically, a plug hole 7 is formed through the middle of the fixing block 6 , and the plug post 8 is slidably plugged into the plug hole 7 .

[0028] Specifically, a slide groove 15 is provided on the top of the mounting plate 2 , and the connecting block 13 is slidably engaged in the slide groove 15 .

[0029] In this embodiment, the water level height of the gate 1 is adjusted. The staff inflates or deflates the air bag 3 to adjust the size of the air bag 3, and then changes the inclination angle of the gate 1 to adjust the water level. This is a mature existing technology and will not be described in detail herein. During the adjustment process, the gate 1 drives the connecting block 13 to slide in the slide groove 15 through the connecting rod 4.

[0030] Specifically, a bolt hole 14 is formed through the top of the connection block 13 , a fixing hole 16 matching with the bolt hole 14 is formed on the top of the mounting plate 2 , and the bolt matches with the bolt hole 14 .

[0031] In this embodiment, when the air bag 3 needs to be removed for maintenance or replaced, the staff will inflate the air bag 3 to the maximum, so that the gate 1 drives the connecting block 13 and the bolt hole 14 to move, so that the bolt hole 14 is aligned with the fixing hole 16, and the staff will screw the bolt into the bolt hole 14 and the fixing hole 16, thereby fixing the gate 1.

[0032] Specifically, the linkage mechanism includes a linkage column 11, which is slidably installed inside the fixing hole 16. A rope 10 is slidably installed through the middle of the linkage column 11 to drive the insertion column 8 to disengage from the insertion hole 7 and release the fixation of the airbag 3. A yield groove 12 that cooperates with the rope 10 is opened on the outer side of the linkage column 11.

[0033] Specifically, one end of the rope 10 is fixedly mounted on the inner side of the mounting plate 2 , and the other end is fixedly mounted on the end of the plug column 8 . A spring 9 is fixedly mounted between the end of the plug column 8 and the inner side of the mounting plate 2 for resetting the plug column 8 . The spring 9 is movably sleeved on the outer periphery of the rope 10 .

[0034] In this embodiment, during the downward movement of the bolt, the linkage column 11 is squeezed, and then the plug column 8 is driven to move out of the plug-in hole 7 by pulling the rope 10, and the spring 9 is compressed. At this time, the fixing block 6 loses its restriction, and the staff can move out the old mounting plate 2 and the air bag 3, and replace them with the new mounting plate 2 and the air bag 3. The staff rotates and takes out the bolt, and under the elastic force of the spring 9, the plug column 8 is inserted into the plug-in hole 7, and the rope 10 is straightened. This method can ensure that when the air bag 3 is replaced, the gate 1 can normally intercept water, and the air bag 3 can be removed while the gate 1 is fixed. It is simple and convenient, and the replacement efficiency of the air bag 3 is improved.

[0035] How it works:

[0036] The water level height of gate 1 is adjusted by the staff inflating or deflating the air bag 3 to adjust the size of the air bag 3, thereby changing the inclination angle of gate 1 to adjust the water level. This is a mature existing technology and will not be described in detail herein. During the adjustment process, the bolt is not inserted into the bolt hole 14, and gate 1 drives the connecting block 13 to slide in the slide groove 15 through the connecting rod 4.

[0037] When the air bag 3 needs to be removed for maintenance or replaced, the staff will inflate the air bag 3 to the maximum, so that the gate 1 drives the connecting block 13 and the bolt hole 14 to move, so that the bolt hole 14 is aligned with the fixing hole 16. The staff screws the bolt into the bolt hole 14 and the fixing hole 16 to fix the gate 1. During the downward movement of the bolt, the linkage column 11 is squeezed, and then the plug column 8 is driven to move out of the plug hole 7 by pulling the rope 10. The spring 9 is compressed. At this time, the fixing block 6 loses its restriction. The staff can move out the old mounting plate 2 and the air bag 3, and replace the new mounting plate 2 and the air bag 3. The staff rotates and takes out the bolt. Under the elastic force of the spring 9, the plug column 8 is inserted into the plug hole 7, and the rope 10 is straightened. This method can ensure that when the air bag 3 is replaced, the gate 1 can intercept water normally, and the air bag 3 can be removed while the gate 1 is fixed. It is simple and convenient, and the replacement efficiency of the air bag 3 is improved.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
