Embodiment 1

[0035] Example 1: The existing stacking gate is used to control the discharge of upstream water level to the downstream. The main function is to keep the upstream and downstream water temperature basically constant, so as not to affect the biological habits and ecological balance. Compared with the existing stacking gate, it needs to be controlled separately Only multi-layer gates can make the upstream surface water discharge downwards. This embodiment adopts such as figure 1 The single-door gate 3 structure shown,figure 1 It is a front view of the side facing the water of the gate 3. The gate 3 has the function of a stoplog gate and has the function of opening and closing automatic drainage. Compared with the existing multi-layer combined beam gate, the structure and driving part of the gate 3 are simplified, and the operation is simple. Since there is no problem of cooperation between multiple gates, the water-stop performance is improved.

[0036] From figure 1 It can be s...

Embodiment 2

[0046] Embodiment 2: On the basis of Embodiment 1, the way of controlling the water baffle can be changed, such as Figure 16 and Figure 17 In the shown structure, the shaft sleeve side of the driving arm 328 is fixed with a swing rod, the swing rod is located in the relief hole, and the end of the swing rod is hinged to the upper end of the tapered lock 307 through a connecting piece. The driving arm 328 is located at the back of the water deflector and can be pressed tightly against the water deflector.

[0047] In this embodiment, the driving arm can move together with the water baffle 313 , that is, after the water baffle is overturned by the pressure of the water, the driving arm is pushed to overturn together to unlock the tapered lock. This function is the same as that of Embodiment 3. At the same time, the driving arm of this embodiment can be turned over independently, that is, after the water retaining plate blocks the water channel 302 of the gate, the independen...

Embodiment 3

[0049] Embodiment 3: This embodiment adopts such as figure 1 The single-door gate structure shown, figure 1 It is the front view of the side facing the water of the gate, which has the function of a stoplog gate and has the function of opening and closing automatic drainage. Compared with the existing multi-layer combined beam gate, the structure and driving part of the gate are simplified, the operation is simple, and the water-stop performance is improved because there is no problem of cooperation between multiple gates.

[0050] From figure 1 It can be seen that the gate track includes an aboveground section 101 of the track located on the upper side of the concrete foundation 201 and an underground section 102 of the track located on the lower side of the concrete foundation 201. The height difference of the aboveground section 101 is not less than that of the underground section 102 of the track. The height difference ratio depends on the situation. After matching the ...

Abstract

The invention discloses an openable automatic drainage structure with a stoplog gate function. The openable automatic drainage structure comprises a gate rail, a gate main body and a concrete foundation. The gate rail comprises a rail overground section vertically located on the upper side of the concrete foundation and a rail underground section located on the lower side of the concrete foundation. Two sides of the gate main body are sleeved in the gate rail in a matched mode and can slide on the rail overground section and the rail underground section. In a water discharging process of the gate, the height of the gate main body can be automatically adjusted according to the height of the upstream water level, and the penable automatic drainage structure belongs to an unpowered automatically-adjusted gate, has the function of a stoplog gate, can replace an existing stoplog gate for use and saves energy and manpower. The gate is of an integrated single-gate structure, the structure issimplified, the failure rate is low, and the water stop performance is good. Lining plates on the left side and the right side can be unlocked through conical locking pieces, so that the lining plateson the two sides and the bottom of a gate rail groove are locked or released.

Description

technical field [0001] The invention belongs to the technical field of gates in water conservancy projects, and in particular relates to a gate drainage structure that can automatically adjust upstream surface water to discharge downstream without power. Background technique [0002] The existing stacked beam gates in water conservancy and hydropower projects are composed of multi-layer stacked beams, and each layer of gates is independent of each other. Each layer of gates must be equipped with a complete set of gate frames (tracks) and independent gates. Common cast iron gates and stainless steel gates, gate weight Large, it is very laborious to open and close, it needs to be driven by electricity, and the multi-layer gates need to be controlled separately, the control workload is heavy, and a lot of maintenance work is required, resulting in free waste. While the existing stack gate is used as a water cut-off gate, it also has the function of releasing water in layers. By...
