In order to avoid signal interference between signal line <NUM> and power supply line <NUM>, an insulating plate is arranged between signal line <NUM> and power supply line <NUM>.

As shown in <FIG>, a control structure is arranged in the dam body <NUM>, wherein one end of the diversion tunnel <NUM> is provided with a controller <NUM>, and the other end of the diversion tunnel <NUM> is provided with a contactor frame <NUM>, that is, the contactor frame <NUM> is arranged towards the downstream face of the gate body <NUM>. In order to connect the controller <NUM> and the contactor frame <NUM>, the gate water supplement device also comprises the line between the contactor frame <NUM> and the controller <NUM>, as well as the tube body <NUM> which is sleeved around the line, wherein the tube body <NUM> is arranged in the diversion tunnel <NUM> to protect the line. The tube body <NUM> can be buried in the dam body <NUM> during the pouring process of the dam body <NUM>, which is convenient and simple to set. Specifically, the material of the tube body <NUM> is steel tube. In order to prevent the water entering the tube body <NUM> from affecting the internal line, the top of the tube body <NUM> is arranged with a water seal plate to prevent the water in the diversion tunnel <NUM> from entering the tube body <NUM>. The line comprises signal line <NUM> and power supply line <NUM>. In order to push the contactor frame <NUM> to move towards the gate body <NUM>, as shown in <FIG>, the gate water supplement device further comprises an elastic member <NUM> arranged between the tube body <NUM> and the contactor frame <NUM>. The structure of the contactor frame <NUM> is preferably arc-shaped structure. Specifically, the elastic member <NUM> is a spring. The elastic member <NUM> drives the contactor frame <NUM> to move, so that the signal terminal <NUM> and the power supply terminal <NUM> of the contactor frame <NUM> enter the signal terminal <NUM> and the power supply terminal <NUM> along the configuration of the conical opening structure, realizing adaptive adjustment to solve the problem that the gate body <NUM> does not fall in place.

In order to prevent the contactor frame <NUM> from moving arbitrarily towards the gate body <NUM>, a sealing cover plate <NUM> is arranged at one end of the tube body <NUM> towards the gate body <NUM>, and the sealing cover plate <NUM> is connected to the controller <NUM> through signal. Specifically, the sealing cover plate <NUM> is made of cork. In order to contact the signal terminal <NUM> and the power supply terminal <NUM> of the contactor frame <NUM>, as shown in <FIG>, the contactor frame <NUM> is provided with a signal contactor <NUM> adapted to the signal terminal <NUM> and a power supply contactor <NUM> adapted to the power supply terminal <NUM>, wherein the signal contactor <NUM> is plugged with the signal terminal <NUM>, and the power supply contact <NUM> is plugged with the power supply terminal <NUM>.

In order to facilitate the installation, removal and maintenance of contactor frame <NUM>, as shown in <FIG>, a manhole <NUM> and an access cover plate used for the seal the manhole <NUM> are arranged on the side wall of tube body <NUM> close to gate body <NUM>. The access cover plate is used to seal the manhole to avoid air leakage, water leakage and other problems.

In the specific implementation process, the gate body <NUM> is lifted and lowered by the elevator <NUM>. Before the gate body <NUM> falls to the predetermined position, the controller <NUM> controls the sealing end cover to be in a sealed state, that is, the contactor frame <NUM> is completely located in the tube body <NUM>, and the elastic member <NUM> is in a compressed state simultaneously. When the gate body <NUM> quickly falls to the predetermined position under the action of the elevator <NUM>, the controller <NUM> opens the sealing cover plate <NUM>, the elastic member <NUM> applies the force to the contactor frame <NUM> to move towards the gate body <NUM>, the signal contactor <NUM> and the power supply contactor <NUM> of the contactor frame <NUM> move towards the gate body <NUM>, and the signal contactor <NUM> enters the conical opening structure of the signal end <NUM> below the signal guide groove, and the power supply contactor <NUM> enters into the conical opening structure of the power supply terminal <NUM> below the power supply guide groove.

During the dam construction, gate lowering, impoundment and operation, the remote control room remotely controls the controller <NUM> according to the data of the water pressure detection probe. When water supplement is required, the controller <NUM> will send a signal to open the first opening and closing member <NUM> and the second opening and closing member <NUM> successively to supply water to the outside. The water flow can also be controlled through the first opening and closing member <NUM> and the second opening and closing member <NUM>. When water supplement is not required, the controller <NUM> sends a signal to close the first opening and closing member <NUM> and the second opening and closing member <NUM>. In extreme cases where the remote control function of the first opening and closing member <NUM> and the second opening and closing member <NUM> is damaged, if the first opening and closing member <NUM> and the second opening and closing member <NUM> need to be opened, the personnel will enter along the diversion tunnel <NUM> and open them manually after reaching the first opening and closing member <NUM> and the second opening and closing member <NUM>. It should be noted that the manual control mode is only used as an emergency standby mode.

As an alternative embodiment, the ecological water supplement channel <NUM> can also be provided with opening and closing member such as a third opening and closing member, a fourth opening and closing member and so on.

As an alternative embodiment, the sealing cover plate <NUM> can also be made of plastic, steel plate and other materials.

As an alternative embodiment, when the sealing cover plate <NUM> is opened, the sealing cover plate <NUM> can be opened by pressurizing and blowing air from the air compressor into the tube body <NUM>. When the pressure in the tube body reaches a preset value, the sealing cover plate <NUM> will be opened under pressure.

As an alternative embodiment, the signal terminal <NUM> and the power supply terminal <NUM> can also be a horn-type opening structure, so as to facilitate accurate docking between the contactor and the contactor end.

As an alternative embodiment, in order to detect the water level and water pressure in the dam, the dam body <NUM> is also provided with a water pressure detection probe and a remote control room, wherein the remote control room is respectively connected to the water pressure detection probe, the elevator <NUM> and the controller <NUM> through signal. The water pressure detection probe transmits the data to the remote control room.

Of course, this embodiment does not specifically define the connection mode between the signal contactor <NUM> and the signal terminal <NUM>, and the connection mode between the power supply contactor <NUM> and the power supply terminal <NUM>. In other embodiments, the signal contactor <NUM> and the signal terminal <NUM>, and the power supply contact <NUM> and the power supply terminal <NUM> can also be connected through wireless transmission communication respectively.
