[0002] When multiple gates are arranged in a large-span river channel, since each gate needs to be equipped with a driving device to drive the opening and closing of the gate, a tall pier is generally required between two adjacent gates to accommodate the driving device room for installing the driving device, forming a tall pier water-blocking section, which creates obstacles to flood discharge. Summary of the invention

[0003] The present invention provides a water retaining device for a large-span river channel, which can greatly reduce the water blocking area generated by the pier when the gate is open, thereby increasing the efficiency of the gate when discharging flood water.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

In the present invention, the extension and retraction of the push rod can drive the crank arm to rotate and thus drive the gate to rotate around the gate rotation axis, thereby realizing the opening and closing of the gate.

[0006] Another technical solution of the present invention is based on the above solution, wherein the water retaining device comprises at least two gates, and when the gates are in a water retaining state, the gate leaves of two adjacent gates are in sealed contact.

The partitioning device is arranged between adjacent gates. When the gates are in a water retaining state, the door leaves of the adjacent gates are in sealing contact with the partitioning device.

[0008] Dividers can be used to install decorative objects such as fountains, sculptures, lights, etc.

[0009] Another technical solution of the present invention is based on the above solution, wherein the sealing contact is achieved by a second sealing device, and the gap of the second sealing device is adjustable.

[0010] The sealed contact enables water storage and ensures the water level height of the stored water.

[0012] Another technical solution of the present invention is that, based on the above solution, the driving device is provided with a locking device. The locking device can lock the gate at multiple rotation angles to control the flood discharge or water storage. In the present invention, the driving device can use one or more conventional driving devices such as a cylinder, an oil cylinder, and a motor as a power source.

[0013] Another technical solution of the present invention is based on the above solution, wherein the water retaining device is provided with a driving device chamber, and the push rod is arranged in the driving device chamber.

[0014] Another technical solution of the present invention is that, based on the above solution, the water retaining device further comprises a corridor, and the corridor is communicated with the driving device chamber, so that maintenance can be facilitated by entering through the corridor.

[0015] Another technical solution of the present invention is that, based on the above solution, one driving device can drive multiple gates at the same time.

[0032] In conjunction with the accompanying drawings, the technical solution of the present invention is further described:

[0033] like Figure 1-11 The figure shows a schematic diagram of a water retaining device of the present invention in which the gate is in a fully closed water retaining state, comprising: a water retaining device, comprising three gates 1, a driving device 2, the driving device 2 comprising a push rod 201 and a crank arm 202, the push rod 201 being connected to the crank arm 202, the gate 1 comprising a gate rotating shaft 3 and a gate leaf 8, the crank arm 202 being connected to the gate rotating shaft 3, the push rod 201 being located below the horizontal plane where the center of the gate rotating shaft 3 is located, and at least one crank arm 202 rotates below the horizontal plane where the center of the gate rotating shaft 3 is located.

[0034] Furthermore, when the gate 1 is in a water-blocking state, the gate leaves 8 of two adjacent gates 1 are in sealed contact.

[0035] Furthermore, a partition device may be included between two adjacent gates 1, and when the gates 1 are in a water-blocking state, the gate leaves 8 of the adjacent gates 1 are in sealing contact with the partition device.

[0036] Furthermore, the sealing contact is achieved through a second sealing device 7, and the gap of the second sealing device 7 is adjustable.

[0037] Preferably, the second sealing device 7 comprises a sealing strip bearing member 702 , a sealing strip 701 and an adjusting bolt, wherein the adjusting bolt is used to adjust the relative position between the sealing strip bearing member 702 and the side of the door leaf 8 .

[0038] Furthermore, the driving device 2 is provided with a locking device, which can lock the gate 1 at multiple angles.

[0039] Furthermore, the water retaining device is provided with a driving device chamber 4 , and the push rod 201 is arranged in the driving device chamber 4 .

[0040] Furthermore, a first sealing device 6 is provided between the gate rotating shaft 3 and the driving device chamber 4 .

[0041] Furthermore, the water retaining device also includes a corridor 5 , and the corridor 5 is communicated with the driving device chamber 4 .

[0042] Furthermore, the driving device 2 may include multiple driving devices, each of which drives the gate 1 to rotate; or one driving device 2 may be used to drive multiple gates 1 at the same time.

[0043] When the gate 1 is in the open flood discharge state, the driving device 2 drives the crank arm 202 to rotate, and rotates the gate leaf 8 to a nearly horizontal position in the downstream direction. Since the position of the driving device chamber 4 is relatively low, the foundation structure outside the driving device chamber 4 is also below the horizontal plane. Therefore, when the gate 1 is in the open flood discharge state, there is no water blocking obstacle on the water surface. If a partition device is set between adjacent gates 1, since the position of the driving device chamber 4 is relatively low, the foundation structure outside the driving device chamber 4 is also below the horizontal plane, the partition device is set above the foundation structure outside the driving device chamber 4. Since the partition device does not need to accommodate the driving device, the required size and shape of the partition device can be flexibly adjusted according to the scene requirements, such as installing fountains, lights, sculptures, etc., therefore, the water blocking area on the water surface can be greatly reduced.

[0044] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and changes without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
