Description

Sluice gate

Technical Field

The utility model relates to a sluice.

Background

Sluice is a common device for hydraulic engineering, which is known for intercepting water flows. Prior art water gates typically include a gate that is driven by a screw to close or open the doorway.

The water gate in the prior art has the following defects:

1. the bottom of the doorway is a flat ground, after the doorway is used for draining water, hard blocks can be left on the ground, and if the blocks are not manually cleared, the falling of the gate can be prevented, or a certain gap is formed between the falling gate and the ground, so that the gate is not closed tightly.

2. The gates are generally formed by welding metal plates that approximate a rigid body, and the final stage of falling of the gates into contact with the ground may generate impacts with the ground, which may damage the ground cast with concrete.

3. The bottom of the gate can incline relative to the ground due to installation errors after the gate is installed, and the inclination results in the following results: when the gate is completely dropped, only one side of the bottom of the gate is in contact with the ground, which not only increases the pressure of the gate to the ground (the pressure increases, making the pressed bottom more easily damaged), but also results in a less tight closure of the gate.

4. The screw and the gate are rigidly and fixedly connected, and the screw is easily subjected to transverse force due to installation errors, and the transverse force easily causes the deformation of the screw.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1 to 4, the disclosed embodiment of the present invention discloses a sluice, which comprises: frame 20, fulcrum 40, screw rod 30, hand wheel 50.

The frame 20 comprises a bottom beam 21 and two vertical beams 22, and the bottom beam 21 and the vertical beams 22 can be made of section steel. The base beam 21 is buried in the ground 100 made of concrete and protruded above the ground 100, and the base beam 21 has a protrusion 211 protruded from the ground 100 in an inverted V shape, which makes it difficult for blocks to remain on the base beam 21. Two vertical beams 22 are respectively located on both sides of the bottom beam 21, and the two vertical beams 22 are buried in a concrete-poured vertical wall.

The lower end of the stay 40 is embedded in the upper part of the standing wall, and the top of the stay 40 has a horizontal plate 41, and the horizontal plate 41 is perpendicular to the stay 40.

The gate 10 is located below the cross plate 41 of the stay 40, and the gate 10 is moved up and down to open or close the doorway defined by the vertical beam 22 and the bottom beam 21.

The bottom of the gate 10 is formed into an inverted V-shaped concave portion 11, a V-shaped strip 14 is bonded to the concave portion 11, and the V-shaped strip 14 is bonded to the concave portion 11 via a rubber layer 15, specifically, the rubber layer 15 is heated to a semi-molten state to bond the V-shaped strip 14 to the rubber layer 15. The rubber layer 15 has a certain thickness, so that the V-shaped strip 14 can be cushioned when being impacted.

As shown in fig. 2, the V-shaped strip 14 of the bottom of the lock gate 10 is opposed to the projection 211 of the bottom beam 21, which causes the projection 211 to project into the V-shaped strip 14 after the lock gate 10 is lowered.

The top of the gate 10 is formed with a connecting plate 13, the connecting plate 13 is perpendicular to the gate 10, the lower end of the screw 30 is connected to the connecting plate 13 by a hinge mechanism 60, and the upper end of the screw 30 penetrates through the transverse plate 41 of the support plate 40. As shown in fig. 1, specifically, the hinge mechanism 60 includes a hinge base 61, a ball 62, and a cover plate 70. The hinge seat 61 is fixed on the connecting plate 13 by a fastener, a spherical recess is formed in the upper end of the hinge seat 61, the ball 62 is formed at the lower end of the screw 30, the ball 62 is embedded in the spherical recess of the hinge seat 61, and the cover plate 70 is fastened on the upper end of the hinge seat 61 by the fastener to limit the ball 62 from being released from the spherical recess of the hinge seat 61. A bushing 70 is fixed on a through hole on the transverse plate 41 through which the screw 30 passes, a key 71 is arranged on the inner wall of the bushing 70, correspondingly, a key groove 31 (as a limiting part) is arranged on the screw 30, the key groove 31 extends along the length of the screw 30, and the key 71 extends into the key groove 31, so that the screw 30 can only vertically move but cannot rotate.

The hand wheel 50 is sleeved on the screw rod 30 and located above the transverse plate 41, the hand wheel 50 and the screw rod 30 form a threaded connection, so that the screw rod 30 can be forced to move up and down by rotating the hand wheel 50, and then the gate 10 is driven to move up and down to open and close the doorway.

The vertical beam 22 is provided with a guide groove 221 with a notch facing the gate 10, a guide rail 12 matched with the guide groove 221 is formed on the side edge of the gate 10, and the guide rail 12 extends into the guide groove 221 so as to limit the movement of the gate 10 in the thickness direction.

When it is desired to close the gate 10, the hand wheel 50 is rotated and the screw 30 is moved downwardly, the gate 10 falls under gravity and guided by the guide groove 221, and finally the inverted V-shaped protrusion 211 of the bottom beam is caused to extend into the V-shaped bar 14 to close the gate.

The utility model provides a sluice's advantage lies in:

1. through the bulge 211 that forms the shape of falling V on making ground 100, and then can effectively avoid the cubic to persist on the floorbar (the inclined plane structure of V-arrangement structure makes the cubic can not stable stop), so, can significantly reduce the probability that the cubic that is relative with the bottom of gate 10 is vertical persists, and then can provide gate 10 bottom and ground 100 degree of strictness greatly.

2. Even if a small amount of the block remains on the projection 211, since the V-shaped strip 14 at the bottom of the shutter 10 is used to engage with the projection 211, when the V-shaped strip 14 is near the projection 211, the pressure of the V-shaped strip 14 against the block causes the block to slide off the projection 211 along the slope of the projection 211.

3. The rubber layer 15 between the V-shaped strip 14 and the bottom of the gate 10 can play a good role in buffering at the moment when the gate 10 falls and contacts the ground 100, so that the probability of damage to the ground 100 due to impact can be reduced to the greatest extent.

4. The rubber layer 15 can compensate for the inclination of the bottom of the gate 10 by deformation, so that an uneven gap between the V-shaped strip 14 and the protrusion 211 can be effectively avoided, and an excessive pressure on one side can be effectively avoided.

5. The screw 30 is hinged to the gate 10, so that the screw 30 is only under the action of gravity of the gate 10, and the screw 30 can be effectively prevented from being stressed transversely, and the screw 30 is effectively prevented from being bent, so that the hand wheel 50 and the screw 30 are more smoothly in spiral transmission.
