Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy gates, in particular to a gate. Background Art

[0002] In the hot summer, in order to ensure the normal growth of crops in the fields, people usually divert some water to the canal to irrigate the crops. Usually, this water is blocked by the gate to prevent it from pouring in and causing waterlogging of the crops.

[0003] When the existing gate is opened, as the water in the canal flows, some stones and soil at the bottom of the canal will easily flow. If the gate is just closed, a lot of stones will gather at the bottom of the gate plate. For some current remote intelligent control gates, the users are generally not on site, resulting in these stones being unable to be cleaned. As a result, when the gate moves down, these stones are likely to contact and collide with the lower end surface of the gate plate, causing damage to the gate plate. Over time, this will cause the throttling effect of the gate to deteriorate. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a gate, which, in actual use, can effectively avoid the gate from being damaged by using a first gate plate and a second gate plate, thereby increasing the service life of the entire gate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A gate comprises a mounting frame, wherein the mounting frame is penetrated by a mounting opening in a front-to-back direction, a first gate plate is arranged in the mounting opening, a first motor is mounted on the upper end of the mounting frame, a first threaded groove is opened on the upper end of the first gate plate, an output shaft of the first motor extends into the mounting opening and is fixedly connected with a first threaded rod, a lower end of the first threaded rod extends into the first threaded groove and is threadedly connected to the inner wall of the first threaded groove; and a lower gate plate mechanism, wherein the lower gate plate mechanism cooperates with the first gate plate.

[0007] Preferably, guide grooves are provided on both the left and right sides of the installation opening, and the left and right sides of the first gate plate extend into the corresponding guide grooves respectively and are slidably connected to the inner walls of the corresponding guide grooves.

[0008] Preferably, the lower gate mechanism comprises a slide groove provided at the bottom of the installation opening, and a second gate which can slide up and down is arranged in the slide groove.

[0009] Preferably, a second motor is installed at the inner bottom of the slide groove, the output shaft of the second motor is fixedly connected to a second threaded rod, a second threaded groove is opened at the lower end of the second gate plate, the upper end of the second threaded rod extends into the second threaded groove and is threadedly connected to the inner wall of the second threaded groove.

[0010] Preferably, the lower end surface of the first gate plate and the upper end surface of the second gate plate are both inclined, and the lower end surface of the first gate plate and the upper end surface of the second gate plate match each other.

[0011] Preferably, the first motor and the second motor are both servo motors capable of changing the rotation direction.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] During actual use of the gate, the movement of the first gate plate can be supported by the setting of the guide groove, so that the overall force is more evenly distributed, and the impact force of the water is prevented from acting completely on the first gate plate and the second gate plate. Through the use of the second gate plate, during the upward movement, since the upper end face of the second gate plate is inclined and moves relative to the water body, the mud and gravel on its upper end face will fall off. In this way, when the first gate plate contacts the second gate plate, the overall sealing effect is better, and no damage is caused to the contact surface, thereby increasing the actual service life.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3A gate comprises a mounting frame 1, wherein the mounting frame 1 is provided with a mounting opening 2 in the front-to-back direction, a first gate plate 6 is provided in the mounting opening 2, a first motor 4 is installed at the upper end of the mounting frame 1, a first threaded groove 11 is provided at the upper end of the first gate plate 6, an output shaft of the first motor 4 extends into the mounting opening 2, and is fixedly connected with a first threaded rod 5, and a lower end of the first threaded rod 5 extends into the first threaded groove 11, and is threadedly connected with an inner wall of the first threaded groove 11;

[0020] The left and right sides of the installation opening 2 are both provided with guide grooves 3, and the left and right sides of the first gate plate 6 extend into the corresponding guide grooves 3 respectively and are slidably connected with the inner walls of the corresponding guide grooves 3;

[0021] Among them, it also includes a lower gate mechanism, which cooperates with the first gate 6. The lower gate mechanism includes a slide groove 8 opened at the bottom of the installation port 2, and a second gate 10 that can slide up and down is arranged in the slide groove 8. A second motor 9 is installed at the inner bottom of the slide groove 8. The output shaft of the second motor 9 is fixedly connected with a second threaded rod 7. A second thread groove 12 is opened at the lower end of the second gate 10. The upper end of the second threaded rod 7 extends into the second thread groove 12 and is threadedly connected to the inner wall of the second thread groove 12. The lower end surface of the first gate 6 and the upper end surface of the second gate 10 are both inclined. The lower end surface of the first gate 6 The end face and the upper end face of the second gate plate 10 cooperate with each other. The first motor 4 and the second motor 9 are servo motors that can change the rotation direction. In order to improve the use effect, the second motor 9 is a submersible motor. The servo motor can control the speed and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0022] In the utility model, when the gate is installed, the inner bottom of the installation opening 2 is flush with the inner bottom surface of the water channel. The staff can drive the first gate plate 6 to move up by starting the first threaded rod 5, so that the water can pass through the gate. When the gate needs to be closed later, the second motor 9 can be started first to rotate the second threaded rod 7, so that the second gate plate 10 can be moved up, so that the second gate plate 10 moves up to the lower end surface of the first gate plate 6. In the process of moving up, since the upper end surface of the second gate plate 10 is inclined and moves relative to the water body, the mud and gravel on its upper end surface will fall off. In this way, when the first gate plate 6 contacts the second gate plate 10, the overall sealing effect is better, and the contact surface will not be damaged, thereby improving the actual service life. Then the first motor 4 and the second motor 9 are started to rotate synchronously in the opposite direction, so that the first gate plate 6 and the second gate plate 10 are synchronously moved down to Figure 1 Location is fine.
