Gate device for small water conservancy project

Abstract

The invention relates to a gate device for a small water conservancy project, and relates to the technical field of water conservancy projects. The lower end of a guiding rod is fixed to a protectingplate, and the surface of the protecting plate is coated with an anti-oxidation coating, the protecting plate is arranged on the side face of a gate plate and is in fit arrangement with the side faceof the gate plate, the protecting plate is movably arranged in a gate frame below a cross bar in an up and down mode, a second bearing base is fixed to the top surface of the protecting plate, the lower end of a screw rod is inserted into a bearing fixed in the second bearing base, the screw rod is rotationally fixed on the cross bar through a screw rod base, the upper part of the screw rod is rotationally connected with an inner threaded sleeve through a ball bearing, the ball bearing is embedded in the first bearing base, the first bearing base is fixed on the side surface of the top edge ofthe gate frame, and an protecting plate lifting hand wheel sleeves the outer part of the inner threaded sleeve. The gate device can increase the oxidation resistance of the gate plate according to the using condition, the service life of the gate is effectively prolonged, meanwhile, impurities deposited at the bottom of the gate frame can be effectively eliminated, and the sealing performance ofthe gate plate is improved.

Description

technical field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a gate device for small water conservancy projects. Background technique

[0002] The gate is used to close and open the control facility of the discharge (discharge) channel. An important part of hydraulic structures, it can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc.

[0003] Because the gate plate has been in contact with water for a long time, the interface between the two is prone to oxidation, and the oxidized gate plate is prone to damage, which affects the normal closure and discharge of water conservancy. At the same time, after the gate is put into use for a long time, the impurities entrained in the water etc. are easy to deposit at the bottom of the gate frame, affecting the closing of the gate plate, which needs to be improved urgently.

specific Embodiment approach 2

[0045] see Figure 10-Figure 13 , the difference between this specific embodiment and the specific embodiment one is: the protective plate lifting hand wheel 7-2 is replaced by a driven gear 7-9, and the driven gear 7-9 in the two protection mechanisms 7 is all connected with the driving gear 7-11 meshing setting, the driving gear 7-11 is socketed and fixed on the output shaft of the motor 7-10, the motor 7-10 is fixed on the top surface of the gate frame 1, the motor 7-10 is connected to the external power supply, and the rest of the structure and The connection relationship is the same as that in the first embodiment.

[0046] The motor 7-10 in this embodiment drives the driving gear 7-11, thereby driving the driven gear 7-9 to rotate, which solves the time-consuming and labor-intensive problems caused by manually pulling the protective plate to lift the handwheel.
