[0027] Example 1

[0028] As attached Figure 1 and attached Figure 2As shown, this embodiment provides a tailrace gate bottom water seal installation structure that is easy to maintain, including a water seal strip fixing seat 1, a water seal strip 2 fixedly installed at the bottom of the water seal strip fixing seat, and multiple steel ball locking cylinders 3 evenly spaced on the gate bottom plate.

[0029] As attached Figure 2 As shown, the steel ball locking cylinder 3 includes a fixed cylinder 3.1, a cylinder body 3.2, a piston rod 3.3, a spring 3.4, and multiple steel balls 3.5. The fixed cylinder 3.1 is fixedly installed in a through hole in the gate bottom plate; the installation method can be welding or threaded connection. The top of the cylinder body 3.2 is screwed to the bottom of the fixed cylinder 3.1. The outer wall of the bottom of the cylinder body 3.2 has multiple through holes, and the multiple steel balls 3.5 are movably disposed within these through holes. The piston rod 3.3 is fitted with a spring 3.4 and movably disposed within the cylinder body 3.2. The bottom of the piston rod 3.3 has a groove 3.3.1, preferably a groove with inclined surfaces at both ends. The length of the groove is greater than the diameter of the steel ball, and the depth is sufficient to ensure that the steel ball does not protrude from the outer surface of the cylinder body after entering the groove.

[0030] The top of the water seal fixing seat 1 is provided with a plurality of locking holes 1.1 corresponding to the steel ball locking cylinder 3. The locking hole 1.1 is provided with a conical surface 1.1.1. The steel ball 3.5 is pushed towards the conical surface 1.1.1 by the piston rod 3.3 of the steel ball locking cylinder 3, and the water seal fixing seat is locked by the steel ball pressing the conical surface.

[0031] The working principle of the steel ball locking cylinder locking water seal strip fixing seat in this embodiment is as follows: Under normal conditions, the piston rod is supported by the elastic force provided by the spring. At this time, the groove is above the steel ball, and the steel ball is squeezed out under the action of the piston rod. The steel ball acts on the inclined surface of the through hole, locking the water seal strip fixing seat; when the piston rod is moved downward, the steel ball enters the groove, as shown in the attached figure. Figure 4 As shown, the steel ball separates from the inclined plane, releasing the water seal fixing seat. Using this type of steel ball locking cylinder, air pressure is only required during assembly and disassembly, resulting in very low air consumption.

[0032] Preferably, in this embodiment, a rubber pad 4 is provided at the bottom of the gate base plate or at the top of the water seal fixing seat 1 to ensure the seal between the water seal fixing seat and the gate base plate.

[0033] Preferably, the ball-locking cylinder 3 in this embodiment is a pneumatic ball-locking cylinder, with an air pipe 5 connected to its top. The air inlet of the air pipe 5 is located on the tailrace gate. In this embodiment, compressed air drives the piston rod to move downward. In other embodiments, a push rod can also be used to push the piston rod, and the push rod is also fixed to the gate.

[0034] In this embodiment, the steel ball locking cylinder 3 can be provided with one row or two rows in parallel as needed, and setting two rows of locking cylinders is more reliable.

[0035] Preferably, in this embodiment, the upstream side of the water seal strip fixing seat 1 is provided with a water seal strip mounting groove 1.2, and the water seal strip 2 is embedded in the water seal strip mounting groove 1.2 and fixed to the water seal strip fixing seat 1 by a pressure plate 1.3 and bolts 1.4. The modular design facilitates quick disassembly of the entire module before the water seal strip is installed or removed, greatly reducing the operational difficulty compared to installing or removing the water seal strip on the gate.

[0036] Preferably, the bottom of the pressure plate 1.3 in this embodiment is provided with a 45° slope, which can effectively reduce the impact of water flow on the water seal strip.

[0037] Example 2

[0038] As attached Figure 1 and attached Figure 2 As shown, in this embodiment, the gate panel is also provided with multiple dovetail-shaped guide rails 6 arranged at equal intervals, and the water seal strip fixing seat 1 is provided with multiple dovetail-shaped guide grooves 1.5 that slide with the guide rails. This design allows the guide rails to play a positioning and guiding role during the installation of the water seal strip fixing seat, reducing the installation difficulty.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
