Description

Technical Field

[0001] The utility model relates to the field of steel gates, in particular to an anti-collision steel gate. Background Technique

[0002] A gate is a control facility used to close and open a water discharge (release) channel and an important part of a hydraulic structure. It can be used to intercept water flow, control water level, regulate flow rate, discharge sediment and floating objects, etc. Currently, the steel gate usually uses a lifting structure to move the gate vertically to achieve the function of intercepting water flow. However, during the process of blocking water flow, the gate is often collided by water flow or impurities in it. After long-term collision, the gate is severely damaged, reducing its service life.

[0003] The anti-collision structure of the current steel gate generally installs an anti-collision plate in front of the gate body. When large stones in the rapid water flow impact the anti-collision plate, the impact force will still be transmitted to the gate body, and the anti-collision effect is limited, which is likely to cause damage to the gate and it is difficult to improve the protection of the gate.

[0026] As Figure 1-6 shown, an anti - collision steel gate includes a door frame 2 and a door body 1. A chute matching the door body 1 is provided on the inner wall of the door frame 2, and a roller 9 is installed in the chute. An opener 3 is installed on the top surface of the door frame 2. The output end of the opener 3 is connected to a lead screw 4. A threaded seat 5 matching the lead screw 4 is connected to the back of the door body 1. A receiving pipe 6 for receiving the lead screw 4 is connected to the back of the door body 1. The receiving pipe 6 is located below the threaded seat 5. A fixed plate 10 is connected to the bottom of the door frame 2. A plurality of anti - collision columns 11 are evenly connected to the top surface of the fixed plate 10. An anti - collision net 12 is arranged behind the plurality of anti - collision columns 11. When the door body 1 is closed, the anti - collision net 12 is located directly in front of the door body 1.

[0027] As Figure 4 shown, the door frame 2 is divided into a working cavity 1 - 1 and a water - passing cavity 1 - 2 by a cross - beam. The working cavity 1 - 1 is located above the water - passing cavity 1 - 2. Cover plates 7 are installed on the front and back sides of the working cavity 1 - 1. A handle 8 is connected to the outside of the cover plate 7. The anti - collision net 12 is installed in front of the water - passing cavity 1 - 2. When the gate is closed, the door body 1 is located in the water - passing cavity 1 - 2. When the gate is opened, the door body 1 is located in the working cavity 1 - 1.

[0028] During operation, the opener 3 drives the lead screw 4 to rotate. The rotation of the lead screw 4 drives the threaded seat 5 and the door body 1 to move upward. When the door body 1 moves into the working cavity 1 - 1, the gate is fully opened, and water can pass through the water - passing cavity 1 - 2.

[0029] As shown Figure 2 in the figure, the anti-collision column 11 includes a central rod 11-1. The bottom end of the central rod 11-1 is connected to the top surface of the fixing plate 10. A plurality of anti-collision plates 11-3 are arranged on the outer side of the central rod 11-1. The plurality of anti-collision plates 11-3 are evenly distributed in a circumferential manner. The anti-collision plates 11-3 are connected to the outer wall of the central rod 11-1 through spring shock absorbers 11-2; a plurality of the spring shock absorbers 11-2 are installed between the inner wall of the anti-collision plate 11-3 and the outer wall of the central rod 11-1, and the plurality of spring shock absorbers 11-2 are evenly distributed in the vertical direction; in addition, a rubber buffer layer or protrusions can be installed on the outer wall of the anti-collision plate 11-3. The protrusions can play a role in pressure relief and protect the anti-collision plate, so that the gate has the effect of resisting compression and collision and extends the service life of the gate; a rubber layer can also be installed on the outer wall of the central rod 11-1. When an object hits the central rod 11-1, the rubber layer plays a protective role.

[0030] The cross-section of the fixing plate 10 is set as a semi-circular ring. The fixing plate 10 surrounds the front side of the water passing cavity 1-2. A plurality of anti-collision columns 11 are evenly connected to the top surface of the fixing plate 10. Large stones and other objects in the water flow first hit the anti-collision columns 11. After the anti-collision plates 11-3 are hit, the energy is transmitted to the spring shock absorbers 11-2. The spring shock absorbers 11-2 play a role in shock absorption and buffering, and can effectively resist the impact of large stones and other objects in the rapid water flow, thereby improving the protection of the gate structure composed of the door body 1 and the door frame 2 and extending the service life of the gate.

[0031] As shown Figure 5 and 6 in the figure, the anti-collision net 12 is connected to the front of the door frame 2 through a connector 13; the connector 13 includes a connecting plate 13-1. The middle part of the connecting plate 13-1 is set as an arc structure. The two sides of the arc structure are connected with plane structures. Connecting bolts 13-2 are arranged on the plane structures. The connecting bolts 13-2 pass through the plane structures and are then connected to the front of the door frame 2; the mesh holes on the anti-collision net 12 can block objects with smaller volumes. Smaller objects in the water flow pass through the gaps between adjacent two anti-collision columns 11 and then hit the anti-collision net 12. Through the interception of the anti-collision net 12, these objects are prevented from hitting the door body 1, further improving the anti-collision performance of the gate.

[0032] The working process of the present utility model is as follows:

[0033] Large objects such as large stones in the water flow first hit the anti-collision column 11. After being hit, the anti-collision plate 11-3 transfers the energy to the spring shock absorber 11-2. The spring shock absorber 11-2 plays a role in shock absorption and buffering, and can effectively resist the impact of large objects such as large stones in the rapid water flow, thereby improving the protection of the gate structure composed of the gate body 1 and the door frame 2; Smaller objects in the water flow pass through the gap between two adjacent anti-collision columns 11 and then hit the anti-collision net 12. Through the interception of the anti-collision net 12, these objects are prevented from hitting the gate body 1, further providing the anti-collision performance of the gate.

Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
