Description

Technical Field

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

[0002] As an important water conservancy engineering facility, water conservancy gates are mainly used to control the water level of rivers. They play a key role in urban drainage, farmland irrigation and hydropower station power generation. The gates can close the openings of buildings as needed, or open the openings completely or partially, thereby regulating the upstream and downstream water levels and flows, and achieving multiple benefits such as flood control, irrigation, water supply, power generation, and navigation.

[0003] In the existing technology, hydraulic gates usually have the following problems: during the operation of hydraulic gates, branches, weeds and other debris are easily accumulated on the gates and their surrounding areas, which may cause the gate frame to be blocked and affect the normal operation of the gate switch. This situation may even cause a gap between the gate and the frame bottom plate, making it impossible to effectively store water in front of the gate. Long-term accumulation of debris may cause physical damage to the gate structure, such as wear and corrosion, shortening the service life of the gate. If the hydraulic gate is stuck by debris during operation, it will increase the load on the motor and cause the motor to overheat. If the motor overheats seriously, it may even cause safety accidents such as fire, posing a threat to the safety of personnel and equipment. Utility Model Content

The bottom of the lifting plate 410 is connected with a lifting rod 407, the outer wall of the lifting rod 407 is threadedly connected with a telescopic tube 406, one end of the telescopic tube 406 away from the lifting rod 407 is threadedly connected to a water tank 408, and the water tank 408 is provided with an integrally formed water outlet 409, and the end of the lifting rod 407 away from the hollow gate 401 is connected with a baffle 403, the top and bottom of the baffle 403 are installed with a one-way water outlet valve 405, and the front and back of the baffle 403 are installed with rubber baffles 404;

[0030] Both ends of the telescopic tube 406 are made of stainless steel, the water tank 408 is integrally formed on the inner wall of the gate frame 1, and the aperture of the water outlet hole 409 gradually increases from top to bottom;

[0031] The rubber baffle 404 is made of polyurethane rubber, and the thickness of the rubber baffle 404 is 3 cm;

The friction coefficient of the deep groove ball bearing is small, which helps to reduce friction loss, thereby increasing the life of the bearing. The structure of the deep groove ball bearing is relatively simple, usually consisting of an outer ring, an inner ring, a group of steel balls and a retaining frame, which helps to reduce manufacturing costs.

[0035] Embodiment 2

[0036] On the basis of the first embodiment, further, as a specific implementation mode of the present utility model, the present utility model provides a water conservancy gate operation abnormal protection device.

[0037] Specifically, by Figure 1 , Figure 2 , Figure 3It is given that a heat dissipation component 5 is provided on the top of the gate frame 1, and the heat dissipation component 5 includes a heat dissipation copper tube 502 installed on the front of the lifting motor 2, and heat dissipation one-way water inlet valves 501 are connected to both ends of the heat dissipation copper tube 502, and the heat dissipation one-way water inlet valve 501 is threadedly connected to the lifting rod 407, and the heat dissipation copper tube 502 is connected to a heat dissipation one-way water outlet valve 503 at one end away from the heat dissipation one-way water inlet valve 501, and the heat dissipation one-way water outlet valve 503 is threadedly connected to the lifting rod 407;

[0038] The heat dissipation copper tube 502 is set to be S-shaped, and the heat dissipation copper tube 502 has a thickness of 0.5 cm and a diameter of 5 cm;

[0039] As the temperature of the lifting motor 2 rises during operation, its operating quality will decline, thereby affecting the working efficiency of the motor. Long-term high-temperature operation will cause the motor insulation material to age, oxidize or even become brittle, reducing the insulation performance of the motor, thereby increasing the risk of short circuit inside the motor. Water is introduced through the heat dissipation one-way water inlet valve 501 threadedly connected to the lifting rod 407, and water is discharged through the heat dissipation one-way water outlet valve 503 threadedly connected to the lifting rod 407. This design allows water to flow continuously through the heat dissipation copper tube 502, thereby taking away more heat and improving the heat dissipation efficiency. Especially in high temperature environments, this method can effectively prevent equipment from overheating and ensure stable operation of the equipment. The S-shaped design of the heat dissipation copper tube 502 can increase the number of heat sinks or the surface area of ​​the heat sink, thereby increasing the heat dissipation area, thereby improving the heat dissipation efficiency and reducing the heat dissipation blind area. In this way, heat can be more evenly distributed to the heat sink, thereby improving the overall heat dissipation effect.

[0040] Working principle: By starting the lifting motor 2 to drive the left and right screws to rotate, the hollow gate 401 and the baffle 403 are controlled to move up and down in opposite directions to generate negative pressure. Due to the negative pressure generated during operation, the water flow will be sucked into the interior of the hollow gate 401 through the one-way water inlet valve 402. Because of the pressure generated by the hollow gate 401 and the baffle 403 moving up and down in opposite directions, the water inside the hollow gate 401 is pressed out from the one-way water outlet valve 405 by the pressure, and the pressed water flows through the installation cavity inside the baffle 403 and the bottom of the lifting rod 407. The cavity, telescopic tube 406 and water tank 408 are ejected from the water outlet 409. The accumulation of silt and debris in the gate frame 1 may cause the gate to be unable to open and close normally, thereby affecting the normal operation of the reservoir. By jetting water, the silt and other residues in the gate frame 1 can be effectively removed. This structure can remove blockages and ensure the normal operation of the sluice. Because both ends of the telescopic tube 406 are made of stainless steel with high mechanical strength, can withstand high water pressure, are not easy to deform or break, and have reliable sealing performance, can It effectively prevents water from leaking from the joint, so the service life of the telescopic tube 406 is increased and the maintenance frequency is reduced. The aperture of the water outlet 409 gradually increases from top to bottom. The design of gradually increasing aperture avoids the influence of different water flow pressure on the cleaning effect and ensures the stability of the water outlet state. The rubber baffle 404 increases the sealing of the baffle 403 and increases the internal pressure of the hollow gate 401 during the operation of the sluice. The rubber baffle 404 made of polyurethane rubber has high elasticity, which makes it excellent in buffering and shock absorption, avoiding the wear caused by direct contact between the inner wall of the hollow gate 401 and the baffle 403. The wear resistance of polyurethane rubber is the highest among all rubbers, which increases the service life of the rubber baffle 404 and reduces the maintenance frequency. The bearings for rotatingly connecting the hollow gate 401 with the left and right screw rods 3 are deep groove ball bearings. The friction coefficient of the deep groove ball bearings is small, which helps to reduce friction loss, thereby increasing the life of the bearings. The structure of the deep groove ball bearings is relatively simple, usually consisting of an outer ring, an inner ring, a group of steel balls and a retaining frame, which helps to reduce manufacturing costs.

[0041] As the temperature of the lifting motor 2 rises during operation, its operating quality will decline, thereby affecting the working efficiency of the motor. Long-term high-temperature operation will cause the motor insulation material to age, oxidize or even become brittle, reducing the insulation performance of the motor, thereby increasing the risk of short circuit inside the motor.
