Description
Technical Field
[0001] The utility model relates to the technical field of gates, in particular to a bottom-opening weir gate combined with a water retaining device. Background Art
[0002] Weirs and sluices are important hydraulic structures built on rivers or channels in water conservancy projects. They mainly use gates to control or regulate the flow of water to achieve a specific purpose. For example, closing the gate to block floods for irrigation, power generation, shipping, industrial and domestic water use, etc.; opening the gate to release water to discharge floods, drain waterlogging, and discharge wastewater, etc. In water conservancy projects, weir and sluice structures are widely used.
[0003] The sluice chamber includes a gate bottom plate, gate piers, gates, hoist chamber, traffic bridge, etc. The conventional practice is to use an upper-opening gate, that is, the gate opens when it is lifted up and closes when it is lowered down. This opening and closing method requires a certain amount of space on the upper part of the gate (between the top of the gate and the bottom of the hoist) to ensure that the gate can be fully opened and closed. For example, the patent document with the existing patent application number 202020993140.4 discloses a fully sealed sluice gate. The advantage of a conventional sluice gate is that after the gates are fully opened, it basically does not affect the flow of water in the river or channel, and can adapt to the requirements of different water retaining heights and downstream flow rates; the disadvantage is that a hoist platform and hoist chamber higher than the top of the pier need to be set on the upper part of the pier, which leads to an increase in the amount of civil engineering work. The hoist platform and columns protrude from the ground. When used in urban rivers, the landscape effect is poor.
[0004] Therefore, a bottom-opening weir gate combined with a water retaining device is needed to overcome the above problems. Utility Model Content
[0005] The purpose of the utility model is to overcome the above-mentioned technical deficiencies and provide a bottom-opening weir gate combined with a water retaining device to solve the problem in the prior art that the upper part of the existing top-opening sluice gate needs to be provided with a hoist platform and a hoist room higher than the top of the pier, which leads to an increase in the amount of civil engineering work, and the hoist platform and the columns all protrude from the ground, so the landscape effect is poor when used in urban rivers.

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0027] See also Figures 1 to 6 The utility model provides a bottom-opening weir gate combined with a water retaining device. The bottom-opening weir gate combined with a water retaining device can discharge flood water by moving the gate downward, and at the same time, can reduce the overall height of the sluice gate, so that a conventional gate with a high height becomes a structure in which an overflow weir and a gate jointly retain water, effectively reducing the investment in civil engineering.
