Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy gate equipment, and in particular relates to a lifting type water conservancy gate. Background Art

[0002] Gates are control facilities used to close and open water discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow rates, and discharge sediment. A lifting hydraulic gate can be installed at the outlets of rivers, lakes and other areas for water storage and flood discharge.

[0003] However, most of the existing lifting water conservancy gates are integrated gates, that is, the gates directly discharge floodwaters after opening, and are unable to intercept and filter the water flow, resulting in the water flow and debris on one side of the gate all flowing into the other side of the gate, or a separate interception device is set to intercept the debris, which is more inconvenient to use.

[0004] Therefore, those skilled in the art have proposed a lifting type hydraulic gate to solve the above-mentioned problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] See also Figure 1-Figure 5 As shown, a lifting type hydraulic gate comprises:

[0031] A gantry 1, a fixing frame 2 is fixedly mounted on the top outer wall of the gantry 1, and a same base 6 is fixed on both ends of the bottom outer wall of the gantry 1;

[0032] A lifting mechanism 3 is fixedly installed inside the fixed frame 2, and a rectangular opening 4 is opened at the center of the top outer wall of the gantry frame 1;

[0033] The gate mechanism 5 is clamped on the inner wall of the base 6, one end of the lifting mechanism 3 passes through the rectangular opening 4 and is fixedly installed on the top outer wall of the gate mechanism 5, a rectangular frame 503 is arranged inside the gate mechanism 5, and a blocking net 504 is clamped on both sides of the inner wall of the rectangular frame 503.

[0034] As can be seen from the above, when it is necessary to open the gate to release water, the lifting mechanism 3 is started, and the gate mechanism 5 is driven to move upward as a whole through the lifting mechanism 3. After the gate mechanism 5 is adjusted to a suitable height, it is convenient for upstream drainage. When it is necessary to filter debris and reduce the amount of debris entering the downstream, the internal components of the gate mechanism 5 are controlled, the rectangular frame 503 is stopped from being lifted, and the debris is filtered through the retaining net 504.

[0035] Specifically, the lifting mechanism 3 includes a stepper motor 301 and an axle fixing seat 305, which are respectively fixedly mounted on the inner walls on both sides of the fixing frame 2, a transmission shaft 303 is fixed to one end of the output shaft of the stepper motor 301, one end of the transmission shaft 303 is inserted into the circumferential inner wall of the axle fixing seat 305, a sleeve 302 is sleeved on the circumferential outer wall of the transmission shaft 303, the sleeve 302 is located directly above the rectangular opening 4, and a nylon rope 304 is fixedly mounted on one end of the sleeve 302.

[0036] As can be seen from the above, starting the stepper motor 301 drives the transmission shaft 303 to rotate, and then drives the sleeve 302 to rotate, and the nylon rope 304 is wound around the surface of the sleeve 302, so as to facilitate the subsequent gate lifting and water release work.

[0037] Specifically, one end of the nylon rope 304 is fixedly mounted on the top outer wall of the gate mechanism 5 .

[0038] As can be seen from the above, the gate mechanism 5 is pulled up by the nylon rope 304, so as to facilitate opening the gate to release water.

[0039] Specifically, the gate mechanism 5 includes a gate body 502, the interior of the gate body 502 is hollow and interconnected from top to bottom, the gate body 502 is clamped on the inner walls around the base 6, a fixing plate 501 is fixedly installed on the top outer wall of the gate body 502, and an electromagnet 505 is fixedly installed on the bottom inner wall of the fixing plate 501, and the electromagnet 505 is located at the upper part of the interior of the gate body 502.

[0040] As can be seen from the above, the stepping motor 301 drives the fixing plate 501 and the gate body 502 to move upward through the nylon rope 304 .

[0041] Specifically, the rectangular frame 503 is adsorbed and fixed by the electromagnet 505 , a slot 7 is formed on the inner wall of the bottom of the base 6 , and the bottom of the rectangular frame 503 is snapped onto the inner wall of the slot 7 .

[0042] As can be seen from the above, when the electromagnet 505 is in the energized state, the rectangular frame 503 moves up along with the gate body 502. When the electromagnet 505 is powered off, the rectangular frame 503 is separated from the adsorption of the electromagnet 505, the gate body 502 moves up, and the rectangular frame 503 remains on the surface of the base 6, intercepting debris through the blocking net 504.

[0043] Working principle: when it is necessary to open the gate to release water, start the lifting mechanism 3, drive the transmission shaft 303 to rotate through the stepper motor 301, and then drive the sleeve 302 to rotate, wrap the nylon rope 304 around the surface of the sleeve 302, adjust the gate mechanism 5 to a suitable height, and then it is convenient for upstream drainage. When it is necessary to filter debris and reduce the amount of debris entering the downstream, disconnect the power supply of the electromagnet 505, and the rectangular frame 503 will be separated from the adsorption of the electromagnet 505, and the gate body 502 will move up, and the rectangular frame 503 will remain on the surface of the base 6, stop lifting the rectangular frame 503, and filter the debris through the retaining net 504.

[0046] As can be seen from the above, the curved rod 11 can be used to hook some floating weeds and other debris when the gate is opened to release water, thereby reducing the debris in the water. The hollow cylinder 10 and the curved rod 11 can be cleaned regularly to facilitate subsequent use.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
