Definitions

  • the invention relates to the technical field of metal structures of water conservancy and hydropower projects, in particular to an efficient and fast stepless layered water intake gate device.
  • reservoirs are the solution to ecological water.
  • One of the key objects of concern for security issues For reservoirs, there will be temperature and density gradients in the water body in the vertical direction.
  • the water quality of water bodies at different depths is different in terms of water temperature, dissolved oxygen, plankton, turbidity, and carbon dioxide. Water taken from different depths has great impact on ecology, Agriculture, aquaculture, human life and the downstream environment have different impacts, so reservoirs usually need to set up stratified water intake facilities.
  • the main purpose of the reservoir is irrigation water and urban domestic water. Because of the greater impact on human physical and mental health, the requirements for water quality are usually higher, and the surface water of the reservoir is often polluted by floating objects or garbage. In order to meet the water quality requirements, water bodies with a certain depth and range must be removed to meet the water quality requirements. Therefore, in addition to controlling pollution sources, it is important to use water bodies that meet ecological water quality requirements. This requires that the reservoir can be used at any depth and Get water within range.
  • the water depth of the downstream channel is generally not large. Due to the turbulent water flow, the vertical component of the circulation velocity is relatively large, so that the upper and lower water bodies are constantly mixed, and the heat exchange between the water surface and the air can be quickly transferred to other parts. Therefore, in the whole
  • the water temperature distribution on the water flow section is basically uniform. Located in the downstream channel of the reservoir, the water temperature is often affected by meteorological conditions, the location of the reservoir discharge hole (hole), the operation and scheduling of the reservoir, the heat exchange between the water body and the river bed, and the natural flow of the tributaries in the interval. Influenced by water heat exchange, etc., it is greatly affected by the discharge temperature of the reservoir.
  • the main purpose of the reservoirs of hydropower projects is to release water that satisfies the natural ecological balance downstream while generating electricity, mainly to release water with high temperature. Therefore, hydropower projects generally draw the surface water of the reservoir to increase the temperature of the discharged water; For hydropower projects in the region, due to the low temperature of the surface water body in winter, water bodies in the middle and lower parts that meet the water temperature requirements must be used in winter. Therefore, for hydropower projects in cold regions, the reservoirs are also required to be able to draw water freely within a relatively large depth range.
  • layered water intake technologies such as setting stacked gates or multi-layer water intake channels at water inlets or water intakes are commonly used in China at present.
  • stacked gates are more widely used, especially in high dams and large reservoirs.
  • hydropower projects such as Jinsha River Baihetan, Jinsha River Xiluodu, Lancang River Nuozhadu, Lancang River Huangdeng, Yalong River Jinping I, Beipanjiang Guangguang, Oujiang Tankeng and other hydropower stations (see Table 1) .
  • the number of orifices of large-scale hydropower projects that have been built in China is large, the water level varies greatly, and the flow rate of the unit is large, which leads to a large control water depth at the top of the stacking beam gate, generally reaching more than 15m.
  • the number of stacked beam gates on the same level is more, and the lifting height is also larger.
  • the Jinsha River Xiluodu Hydropower Station as an example, if the same layer of stacked beam gates is lifted out of the opening, 90 sections of stacked beam gate leaves need to be raised, and the number of operations reaches 90 times. Cumbersome and time-consuming.
  • Table 1 The technical characteristics of layered water intake of some representative large-scale hydropower stations built in China
  • the hoisting equipment needs to grab the stacked beam gate or the overall gate of different gate holes underwater by grabbing the beam at different times. Since the opening and closing of the gate is an underwater operation, it will be affected by the flow rate of the diversion water for power generation, and the lowering depth is relatively large. There will be problems in the process of grabbing the stacking beam gate by the opening and closing equipment: too fast lowering or lifting speed will easily cause the imbalance of the grasping beam Swinging causes it to be stuck by the door slot, alignment of the slot and difficulty in underwater positioning of the stoplog gate, etc.
  • the layered water intake technology with multi-layer water intakes it is necessary to set up multi-layer water intake channels from top to bottom in the water intake along the water flow direction, set gates in each layer of flow channels, and control the gates in each layer of flow channels through hoisting equipment.
  • the gates of each layer of flow channel need to be staggered in the direction of the water flow, which will increase the length of the water intake along the flow direction. It is generally suitable for reservoirs with a small water intake depth. Otherwise, the investment will increase due to the excessive length of the water intake, but it can be realized within a certain range.
  • louver-type technology used in some foreign projects can achieve arbitrary water intake requirements in a certain range, such as the Shasta Hydropower Station in the United States, it is fixed, and the louvers are easily damaged after long-term underwater operation, and the maintenance needs to be drained to reduce the water level.

Description

一种高效快捷的无级分层取水闸门装置 技术领域
本发明涉及水利水电工程金属结构技术领域，尤其涉及一种高效快捷的无级分层取水闸门装置。
背景技术
随着我国经济高速发展和人们生活的不断提高，国家对关系着人们身心健康和环境保护的生态用水安全问题越来越重视，而生态用水的水源地主要为水库，因此，水库是解决生态用水安全问题的重点关注对象之一。对于水库，其水体在铅直方向会存在温度和密度梯度，不同深度的水体，其水质的水温、溶解氧、浮游生物、浑浊度、二氧化碳等是不同的，从不同的深度取水，对生态、农业、水产养殖、人类生活及下游环境带来的影响不同，故水库通常需要设置分层取水设施。
对于水利工程，其水库的主要用途是灌溉用水和城镇生活用水，因对人身心健康的影响较大，通常对水质的要求更高，而水库的表层水往往受漂浮物或垃圾等污染而达不到要求，需取下部一定深度和范围的水体方能达到水质要求，因此，水库水质安全除控制污染源外，重要的是能引用满足生态水质要求的水体，这就要求水库能在任意深度及范围内取水。
对于水电工程，其下游河道的水深一般不大，因水流湍急，环流速度的垂直分量较大，从而使上下层水体不断搅混，水面与空气的热交换量能迅速传递到其它部位，所以在整个水流断面上的水温分布基本上是均匀的，位于水库的下游河道，其水温往往受气象条件、水库泄水孔(洞)位置、水库运行调度、水体与河床的热交换、区间各支流天然来水热交换等影响，其中受水库放流温度的影响较大，放流水温高，河道水温变高，反之则低。根据上述知，水电工程其水库主要用途是在发电的同时下放满足下游自然生态平衡的水体，主要是下放温度较高的水体，因此，水电工程一般引取水库表层水，提高下泄水温；但对于寒冷地区的水电工程，因冬季表层水体温度较低，则在冬季需引用中下部满足水温要求的水体，故对于寒冷地区的水电工程，其水库也要求能在较大深度范围内任意取用水 体。
对于水库取水，目前国内较常采用的是在进水口或取水口设置叠梁闸门或多层取水流道等分层取水技术，其中以叠梁闸门的应用较多，尤其在高坝大库的水电工程中更显突出，比如金沙江白鹤滩、金沙江溪洛渡、澜沧江糯扎渡、澜沧江黄登、雅砻江锦屏一级、北盘江光照、瓯江滩坑等已建水电站(见表1)。根据表1知，国内已建大型水电工程的孔口数量较多，水位变幅大，机组引用流量大，由此导致叠梁闸门顶控制水深也较大，一般达15m以上，因此，操作一层的叠梁闸门次数较多，提升高度也较大，以金沙江溪洛渡水电站为例，若将同一层叠梁闸门提出孔口，需提出90节叠梁闸门门叶，操作次数达90次，运行繁琐且耗时过长。
表1国内部分代表性已建大型水电站叠梁闸门分层取水技术特性
Figure PCTCN2022088079-appb-000001
对于现有较常采用的叠梁闸门，其通常采用门机、台车等移动式启闭设备操作，为“一机多门”布置方式，一台启闭设备需要抓取不同孔口数量的闸门，因此启闭设备需在不同时刻通过抓梁水下抓取不同闸孔的叠梁闸门或整体闸门。由于闸门启闭为水下作业，会受到引水发电过流水体流速的影响，且下放深度较大，启闭设备抓取叠梁闸门过程中会存在：下放或提升速度过快易造成抓梁失衡产生摆动导致其被门槽卡住、入槽对位和叠梁闸门水下定位穿轴困难等诸多不确定风险因数，导致远程控制实现难度大，通常采用现地控制，从而造成现场工作人员 工作强度过大，效率过低；且频繁的操作导致调度容错率差，一旦操作过程中出现叠梁闸门错位被卡住的现象，叠梁闸门操作时间将大幅延长，对电站运行安全及发电效益也会产生一定影响；以已建的某水电站为例，该水电站进水口水平方向同一挡水层设置36扇叠梁闸门，由于叠梁闸门数量多、共用门机、夜间无法操作、操作强度大等原因，正常下放一层门叶耗时约9天，且门机电机功率大，取水时，因门机一直处于运行状态，故能耗较大；此外，因每扇叠梁闸门的所有门叶处于一个门槽内，只能逐级逐层向下提取门叶取用上部水体或逐级逐层下放门叶挡住下部水体。经工程实践，现有较常采用的叠梁闸门技术，存在运行繁琐、耗时过长、能耗较大、且达不到任意深度取用水体要求，尤其在多进水口的水电工程中更加突出。对于设置多层取水口的分层取水技术，需在取水口顺水流向依次从上至下设置多层取水流道，每层流道内设置闸门，通过启闭设备操控每层流道内的闸门，因每层流道闸门在顺水流向位置需错开，这会增加取水口顺水流向长度，一般适用于取水深度不大的水库，否则会因取水口长度过大增加投资较多，但可以实现部分范围内取水，但因闸门启闭为动水操作，其启闭设备容量较大，电机功率大导致能耗大，且启闭闸门的时间依然较长，运行效率较低。国外某些工程采用的百页窗式技术虽可一定范围上实现任意取水要求，比如美国沙斯塔水电站，但为固定式，且百叶窗长期水下操作易损坏，检修维护需泄水降低水位至进水口底槛高程以下，造成水资源浪费，且该技术需用钢结构框架三面围住进水塔或取水塔，用钢量较大，经济性较差；所以，现有技术还存在不足，有待于进一步完善。

由于采用了上述技术方案，本发明的有益效果如下：
(1)分层取水闸门装置每节门叶由活动门瓣和支撑活动门瓣的流道闸组成，活动门瓣通过流道闸内部设置的双作用油泵油缸集成一体式液压机或者电动推杆或者双作用油泵油缸分离式液压机作为活动门瓣启闭装置，门叶之间采用节间连接板通过连接成整体式取水闸门或多套叠梁式取水闸门，整体式取水闸门或叠梁式取水闸门的启闭采用进水口闸井顶部设置的门机或台车进行操作。在运行期间，活动门瓣通过流道闸内设置的活动门瓣启闭装置进行局部开启或全开全闭操 作以调节取水深度，因整体式取水闸门或叠梁式取水闸门与活动门瓣均采用独立的启闭设备，相对传统的逐层逐级取水的将闸门吊出孔口移至门库存放或锁定于闸井顶部技术，普遍存在的启闭设备扬程较高，对于高水位变幅水电工程可达80m以上，逐层逐级操作1扇闸门达几个小时甚至几天操作繁琐、耗时过长等不足，本发明可通过操控整体式取水闸门或叠梁式取水闸门各节门叶的活动门瓣在0至90°之间任意开度启闭，除操作快捷方便外，能在同一时间开启任意活动门瓣或不同组合活动门瓣或所有活动门瓣实现无极分层取水，因无需将门叶提出孔口，所以启闭活动门瓣的行程很短，一般不超过2m，故整个过程的操作时间很短，通常可在10分钟内完成，从而高效快捷地实现了水库取水口较大水深范围内任意深度的无级分层取水要求。
(2)本发明在每节门叶上设置监测仪器用于监测、观测水温和/或水质，可以掌握不同高程处水温水质情况，实时评价闸门分层取水效果，为分层取水措施的运行优化提供数据支撑，实现水温水质精准调控。
(3)流道闸两侧设置锁定板和可拆卸的电缆限位滑筒，电缆限位滑筒由电缆限位滑槽和电缆限位滑槽挡板组成，在闸门检修维护期间，通过闸顶设置的启闭设备提升整体式取水闸门或叠梁式取水闸门至闸井顶部的锁定梁锁定后，拆除门叶之间的螺栓或销轴和电缆限位滑槽挡板，逐层将电缆和信号线移除电缆限位滑筒与门叶脱离，在不增加启闭设备闸井平台以上扬程或轨上扬程情况下，可逐节拆除并移走各节门叶至门库或指定位置实现检修维护。
(4)活动门瓣由活动闸板、框型水封装置、L型P头水封装置或竖向布置P头水封装置组成，框型水封装置设置在活动闸板的下游侧，使作用在活动闸板的水压方向与水封压缩方向保持一致，流道闸上游侧设置与框型水封装置对应的框型止水座板，使框型水封装置在水压较低情况下保持一定的压缩量，有利于密封止水，活动闸板在框型水封装置两侧外部设置条形支承滑道，在活动门瓣处于关闭挡水状态时可将荷载较好的传递至流道闸上，并可防止框型水封装置在水压较大情况下压缩变形过大失效破坏；活动闸板上游两侧设置L型P头水封装置或竖向布置P头水封装置，进水口的取水闸门槽上游边墙设置活动门瓣转动范围内与L型P头水封装置或竖向布置P头水封装置位置对应的止水座板，在活动门瓣0～90°范围内局部开启时，可防止水体从两侧进入流道闸的过流孔；活动 门瓣的竖梁设置连通孔，便于活动门瓣运行时排除梁格内部的水体；活动门瓣在横梁的L型P头水封靠孔口侧位置处设置水封限位挡块或在横梁的竖向布置P头水封装置的橡胶垫后部设置水封限位支承板，可防止活动门瓣上游侧设置的侧水封在侧向压力作用下向孔口侧偏移过大导致与边墙有间隙而封不住两侧水体进入流道闸；止水座板分成上止水座板和下止水座板，下止水座板设置高度略大于闸门顶，且宽度大于活动门瓣全开时水封长度，满足活动门瓣在0～90°范围内开启封水要求，上止水座板宽度与活动门瓣关闭状态时上游侧水封位置对应，满足在闸门检修维护时启闭闸门能正常运行的同时，可节省进水口边墙闸门埋件的投资。
(5)流道闸由上横梁、下横梁及左右箱型边柱焊接组成过流面封闭的钢结构流道孔，并在过流迎水面及出水面均倒圆角，保障了流道闸过流时水流顺畅，继而有效减轻流道闸过流时的振动。
(6)流道闸下游两侧设置侧水封装置，下游侧底部设置底水封装置，下游侧顶部设置底水封支承座板用于支承上一层门叶底水封装置，有效保障各节门叶两侧及底部均能密封止水。
(7)流道闸边柱设置进人孔、门叶节间连接装置安装操作孔，便于电缆限位滑筒内的电缆和信号线从上至下逐层逐级通过进人孔、门叶节间连接装置的安装操作孔后与操作活动门瓣对应的活动门瓣启闭装置，以及流道闸内部设置的监测仪器的连接；活动门瓣启闭装置的电缆和监测仪器的信号线均设置活动接头，便于闸门提至闸门槽孔顶部时拆除。
(8)流道闸上游侧设置反向支承，下游侧设置正向支承、侧向支承，在保障分层取水闸门启闭过程支承限位方式与传统闸门相同情况下，不干扰活动门瓣的正常操作。
(9)在污物很少的取水口或进水口，当分层取水闸门槽的流速较慢时，通过在流道闸内不影响启闭活动门瓣启闭设备运行的部位设置栅片，满足分层取水的同时兼顾拦污，有效减少取水口或进水口的长度，节省拦污栅及清污设备投资。栅片的截面为上下游圆头矩形条结构或上下游流线型头矩形条结构，流道闸过流时，有利于减轻栅片的振动。
(10)取水闸门槽孔顶部的锁定梁采用桥型结构，便于电缆从锁定梁下部穿 出；活动门瓣启闭设备的配电箱设置在取水口上部靠近取水闸门槽孔的平台上，在可减少电缆长度的同时，便于与电缆连接。
