本实用新型的上述技术目的是通过以下技术方案得以实现的：The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:
一种水利水电闸门门槽防冻装置，包括坝体、闸门和浮桶，闸门内侧设有与闸门水平的滑轨，滑轨之间设有与滑轨垂直的通水钢管，通水钢管的两侧分别设有连接杆，连接杆的一侧与通水钢管固定连接，另一侧与滑轨滑动连接，通水钢管内壁上设有若干发热管。A water conservancy and hydropower gate groove anti-freezing device, including a dam body, a gate and a floating barrel. The inside of the gate is provided with a slide rail horizontal to the gate, and between the slide rails is provided a water-passing steel pipe perpendicular to the slide rail. The two water-passing steel pipes Connecting rods are respectively arranged on the sides, one side of the connecting rod is fixedly connected with the water-passing steel pipe, and the other side is slidingly connected with the slide rail, and a plurality of heating pipes are arranged on the inner wall of the water-passing steel pipe.
通过采用上述技术方案，当滑轨滑动连接的连接杆开始上下移动，带动着与连接杆固定连接的通水钢管，进入通水钢管的水，通过发热管进行加热，使半结冰的水与热水混合，从而解决了结冰和水面忽高忽低，没有办法调节高度的问题，同时发热管设有若干个，且都处于通水钢管的内壁上，这样不仅不会造成部分水结冰，而且还节约了通水钢管的空间。By adopting the above technical scheme, when the connecting rod slidably connected to the slide rail starts to move up and down, it drives the water-passing steel pipe fixedly connected with the connecting rod, and the water entering the water-passing steel pipe is heated by the heating pipe, so that the semi-frozen water and Hot water is mixed to solve the problem of freezing and water surface fluctuating, and there is no way to adjust the height. At the same time, there are several heating pipes, and they are all on the inner wall of the water-passing steel pipe, so that not only will not cause part of the water to freeze , but also save the space of the water pipe.
进一步设置：通水钢管底部设有与通水钢管相通的潜水泵。通水钢管与潜水泵相通处设有止水阀。Further setting: a submersible pump connected with the water pipe is provided at the bottom of the water pipe. A stop valve is provided at the connection between the water pipe and the submersible pump.
通过采用上述技术方案，当需要吸水时，通水钢管与潜水泵相通处的止水阀打开，通水钢管通过潜水泵将水吸入内部。当不需要吸水时，与通水钢管和潜水泵相通的止水阀关闭。By adopting the above technical scheme, when water needs to be absorbed, the water stop valve at the communication place between the water-passing steel pipe and the submersible pump is opened, and the water-passing steel pipe sucks water into the interior through the submersible pump. When no need to absorb water, the water stop valve communicated with the water pipe and the submersible pump is closed.
进一步设置：通水钢管上设有倾斜角度为45度喷水管。通水钢管上端与浮桶下表面分别设有挂钩，挂钩上设有挂绳。Further setting: the water-passing steel pipe is provided with a water spray pipe with an inclination angle of 45 degrees.

通过采用上述技术方案，当通水钢管内的水到一定程度，就会通过喷水管往外45度喷出。喷水管喷出的水触碰到闸门时，力过大就会发生反作用力，通过此原理会使水流发生反射，使水在闸门和浮桶之间形成自然循环，以此解决在门槽两侧及电机电缆处经常出现结冰现象。通水钢管和浮桶通过挂钩与挂绳连接在一起，当水平面忽高忽低时，浮桶拉动着通水钢管上下移动。By adopting the above-mentioned technical scheme, when the water in the water-passing steel pipe reaches a certain level, it will be sprayed out at 45 degrees through the water spray pipe. When the water sprayed from the spray pipe touches the gate, the reaction force will occur if the force is too large. Through this principle, the water flow will be reflected, so that the water will form a natural circulation between the gate and the floating bucket, so as to solve the problem of the gate slot. Icing often occurs on the sides and on the motor cables. The water-passing steel pipe and the floating barrel are connected together by hooks and lanyards. When the water level fluctuates, the floating barrel pulls the water-passing steel pipe to move up and down.
进一步设置：潜水泵数量为两个，且到闸门的距离一致。Further settings: the number of submersible pumps is two, and the distance to the gate is the same.
通过采用上述技术方案，当潜水泵开始吸水时，两个潜水泵到闸门的距离一致，可以使两个潜水泵供水均匀，不会因此导致一边倾斜。By adopting the above technical solution, when the submersible pump starts to absorb water, the distances from the two submersible pumps to the gate are the same, so that the water supply of the two submersible pumps can be uniform without causing one side to tilt.
综上所述，本实用新型具有以下有益效果：该水利水电闸门门槽防冻装置，设有若干个发热管，不会造成部分位置水结冰，同时所处在通水钢管内壁上侧，不占用空间，目前大多数水利水电闸门门槽防冻装置喷管采用直管竖直向上喷水，此种方法基本解决了水面结冰的问题，但在门槽两侧及电机电缆处经常出现结冰现象，因此，在通水钢管上设有倾斜角度为45度喷水口，这样当最外侧喷管喷出的水流射到闸门表面上时就会发生反弹，在闸门和浮桶间形成一个自然的环流，从而达到将冰水和热水扰动的效果，喷水管、滑轨同时运动在一个层面，这就有效地杜绝了配套设施的结冰问题，使之更加方便的服务于水利水电工程，更好的治理江河、进行水资源的优化配置。To sum up, the utility model has the following beneficial effects: the water conservancy and hydropower gate groove antifreeze device is provided with several heating pipes, which will not cause water to freeze in some places, and is located on the upper side of the inner wall of the water-passing steel pipe, without freezing. Occupies space. At present, the nozzles of most water conservancy and hydropower gate slot antifreeze devices use straight pipes to spray water vertically upwards. This method basically solves the problem of freezing on the water surface, but ice often occurs on both sides of the gate slot and at the motor cable. Phenomenon, therefore, on the water pipe, there is a water nozzle with an inclination angle of 45 degrees, so that when the water sprayed from the outermost nozzle hits the surface of the gate, it will rebound, forming a natural gap between the gate and the floating bucket. Circulation, so as to achieve the effect of disturbing the ice water and hot water, the water spray pipe and the slide rail move at the same level at the same time, which effectively prevents the freezing problem of supporting facilities and makes it more convenient to serve water conservancy and hydropower projects , to better manage rivers and optimize the allocation of water resources.
