DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1

[0024] Reference Figure 1-3 , a hydraulic gate device, comprising a support frame 1, wherein:

[0025] Grooves 2 are provided on both sides of the inner wall of the support frame 1, and a gate 3 is slidably connected between the grooves 2. A motor 4 is fixedly connected to the upper end of the support frame 1, and the motor 4 is a servo motor. The output end of the motor 4 is fixedly connected to a threaded rod 5 through a connecting shaft, and the threaded rod 5 is connected to the gate 3 through a connecting frame 6. An anti-blocking mechanism 7 for preventing debris from accumulating at the bottom of the groove 2 is connected to the support frame 1. A control box is fixedly connected to the support frame 1, and the control box signal connects the motor 4 and the anti-blocking mechanism 7. The support frame 1 is installed in the gate. When the gate needs to be opened, the control box controls the motor 4 to be powered on and started. After the motor 4 is started, the threaded rod 5 is driven to rotate clockwise for a set number of circles through the connecting shaft. After the threaded rod 5 rotates, the connecting frame 6 moves upward After the gate 3 is moved upward by the set distance, the gate is opened. When the gate needs to be closed, the control box controls the motor 4 to drive the threaded rod 5 to rotate counterclockwise for a set number of turns through the connecting shaft. After the threaded rod 5 rotates, the connecting frame 6 moves downward by the set distance. After the connecting frame 6 drives the gate 3 to move downward by the set distance, the gate is closed. At the same time, the control box controls the anti-blocking mechanism 7 to start. After the anti-blocking mechanism 7 is started, the air blow is released to sweep the bottom end of the groove 2, so that the debris at the bottom end of the groove 2 is separated from the groove 2. When the gate 3 moves downward to close the gate, it will not cause obstruction to the gate 3, and there will be no gap between the bottom end of the gate 3 and the bottom of the gate, thereby improving the sealing effect of the gate on the gate.

[0026] The anti-blocking mechanism 7 includes an air pump 71, which is fixedly connected to the upper end of the support frame 1. The air pump 71 is connected to the control box through a wire. The outlet of the air pump 71 is connected to a conduit 72. An air pipe 73 is fixedly connected inside the support frame 1. Both ends of the air pipe 73 extend to the bottom end of the groove 2. The upper end of the air pipe 73 is connected to the conduit 72 through a connecting pipe 74. The control box controls the air pump 71 to start. After the air pump 71 is started, external air enters the air pump 71 through the air inlet. The gas in the air pump 71 enters the conduit 72, the connecting pipe 74 and the air pipe 73 in turn. The gas in the air pipe 73 is released from both ends of the air pipe 73. The released gas purges the bottom end of the groove 2, so that the debris at the bottom end of the groove 2 is separated from the groove 2.

[0027] The connecting frame 6 includes a fixing plate 61, which is fixedly connected to the upper end of the gate 3. A threaded tube 62 is fixedly connected to the fixing plate 61. The threaded tube 62 is connected to the threaded rod 5. The fixing plate 61 and the threaded tube 62 are an integrated structure. After the threaded rod 5 rotates, the threaded tube 62 moves in the vertical direction. The threaded tube 62 drives the fixing plate 61 to move. The fixing plate 61 drives the gate 3 to move in the vertical direction to control the opening and closing of the gate.

[0028] Working process: the support frame 1 is installed in the gate. When the gate needs to be opened, the control box controls the motor 4 to be powered on and started. After the motor 4 is started, the threaded rod 5 is driven to rotate clockwise for a set number of turns through the connecting shaft. After the threaded rod 5 rotates, the threaded tube 62 moves upward by a set distance. The threaded tube 62 drives the gate 3 to move upward by a set distance through the fixed plate 61, and then the gate is opened. When the gate needs to be closed, the control box controls the motor 4 to drive the threaded rod 5 to rotate counterclockwise for a set number of turns through the connecting shaft. After the threaded rod 5 rotates, the threaded tube 62 moves downward by a set distance. The threaded tube 62 drives the gate 3 through the fixed plate 61. After moving downward a set distance, the gate is closed, and at the same time, the control box controls the air pump 71 to start. After the air pump 71 is started, the external air enters the air pump 71 through the air inlet, and the gas in the air pump 71 enters the conduit 72, the connecting pipe 74 and the air pipe 73 in turn. The gas in the air pipe 73 is released from both ends of the air pipe 73, and the released gas purges the bottom end of the groove 2, so that the debris at the bottom end of the groove 2 is separated from the groove 2. When the gate 3 moves downward to close the gate, it will not cause obstruction to the gate 3, and no gap will be generated between the bottom end of the gate 3 and the bottom of the gate, thereby improving the sealing effect of the gate on the gate.

[0029] Example 2

[0030] The motor 4 and the air pump 71 are fixed to the upper end of the support frame 1 and exposed to the air. In rainy and snowy weather, rain and snow fall on the motor 4 and the air pump 71, which may easily cause damage to the motor 4 and the air pump 71. Figure 2 As another preferred embodiment of the utility model, on the basis of embodiment 1, a protective mechanism 8 for protecting the motor 4 is fixedly connected to the upper end of the support frame 1, and the protective mechanism 8 includes two parallel support plates 81, and the two parallel support plates 81 are fixedly connected to the upper end of the support frame 1, and the upper ends of the two parallel support plates 81 are fixedly connected with a baffle 82, and an anti-corrosion layer is sprayed on the baffle 82. The support plate 81 supports and fixes the baffle 82, and the baffle 82 is located above the motor 4 and the air pump 71. In rainy and snowy weather, rain and snow are blocked to prevent rain and snow from falling on the motor 4 and the air pump 71, and the motor 4 and the air pump 71 are protected to prevent damage to the motor 4 and the air pump 71. The anti-corrosion layer protects the baffle 82 from corrosion, slows down the corrosion rate of the baffle 82, and extends the service life of the baffle 82.

[0031] Example 3

[0032] When the air pump 71 starts to absorb gas from the air, there is a certain amount of dust in the air. The dust in the extracted gas falls into the air pump 71, thereby affecting the operation of the air pump 71. Figure 4 As another preferred embodiment of the utility model, on the basis of embodiment 1, the air inlet of the air pump 71 is connected to a filter mechanism 9 for gas filtering. The filter mechanism 9 includes a box body 91, and the box body 91 is connected to the air inlet of the air pump 71. An opening 92 is provided at the bottom end of the box body 91. A filter screen 93 is fixedly connected to the opening 92. The filter screen 93 is an arc-shaped screen. When the air pump 71 absorbs gas, the air enters the box body 91 through the filter screen 93. When the gas passes through the filter screen 93, the filter screen 93 filters the dust in the air, thereby reducing the dust content in the gas entering the box body 91, thereby avoiding a large amount of dust accumulation in the air pump 71, which will not affect the operation of the air pump 71.
