Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gate anti-freezing devices, and more specifically, to a hydraulic dam gate anti-freezing device. Background Technology
[0002] In the field of water conservancy engineering, hydraulic dams, as a common and important water-retaining structure, are widely used in rivers, canals, and other water bodies, playing a crucial role in regulating water levels, storing water for irrigation, and flood control. The gate components of a hydraulic dam directly affect the normal operation and function of the entire dam. However, in cold regions or environments with low winter temperatures, hydraulic dam gates face severe freezing problems. When the outside temperature drops below freezing, the water near the gate gradually freezes, and the ice layer thickens, causing various adverse effects on the gate. Therefore, hydraulic dam gate freezing devices have emerged. The usual method for preventing sluice gate freezing is to lay pipelines near the gate slot and panel, and use an air compressor to periodically introduce air into the water surface. The high-temperature compressed air is then used to blow open a non-freezing water hose in front of the gate to protect it from freezing and affecting its normal use. Although this method can prevent the gate from freezing, the pipeline layout is relatively complex, making inspection and maintenance difficult. This significantly increases the maintenance difficulty of the gate device and reduces the maintenance efficiency. To address the shortcomings of the existing technology, we propose a hydraulic dam gate anti-freezing device. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a hydraulic dam gate anti-freezing device to solve the problem that the existing gate anti-freezing measures have complicated pipeline layout, which makes their inspection and maintenance difficult and greatly increases the maintenance difficulty of the gate device, thereby reducing the maintenance efficiency of the gate.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hydraulic dam gate anti-freezing device, including a steel gate, an anti-freezing component is provided on one side of the steel gate, a scraper component is provided on one side of the anti-freezing component, a U-shaped frame is symmetrically fixedly installed on the outer surface of one side of the steel gate, a hydraulic rod is rotatably connected to the inner surface of the U-shaped frame, a mounting base is rotatably connected to one end of the hydraulic rod, a protective cover is fixedly installed in the middle of the outer surface of one side of the steel gate, and fixing blocks are symmetrically fixedly installed on both sides of the protective cover;
[0005] The anti-freezing component includes an L-shaped telescopic tube, one end of which is fixedly fitted with a hollow tube. An air outlet is fixedly connected to the outer surface of the hollow tube. Both ends of the hollow tube are symmetrically and rotatably connected with L-shaped fixing rods. A float plate is slidably installed on the outer surface of the L-shaped fixing rod. A threaded screw is threadedly connected to the middle of the inner wall of the float plate. A knob is fixedly installed on the upper outer surface of the threaded screw.
[0006] The L-shaped telescopic tube is fixedly installed in the middle of the inner wall of the steel gate, and the threaded screw is rotatably connected to the inner wall of the L-shaped fixed rod.
[0007] The scraper assembly includes a bidirectional motor. A positive and negative lead screw is fixedly installed on the outer surface of the output end of the bidirectional motor. A connecting ring is threaded onto the outer surface of the positive and negative lead screw. An L-shaped connecting rod is fixedly installed on one side of the outer surface of the connecting ring. A fixing ring is fixedly installed on the upper outer surface of the L-shaped connecting rod. A scraper is fixedly installed on one side of the outer surface of the fixing ring. The bidirectional motor is fixedly installed on one side of the outer surface of the steel gate, located inside the protective cover. The positive and negative lead screw is rotatably connected to one side of the inner wall of the fixing block. The L-shaped connecting rod slides on the inner wall of the steel gate, and the scraper slides on one side of the outer surface of the steel gate.
[0008] One end of the L-shaped telescopic tube is fixedly connected to the output end of the air compressor, and the float plate always floats horizontally on the water surface.
[0009] The gate has two scraper blades, which reciprocate relative to each other on one side of the outer surface of the steel gate.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model features an anti-freezing component, including an L-shaped telescopic tube. Depending on environmental requirements, rotating a knob drives a threaded screw to rotate, which in turn causes a float connected to the outer surface of the protective cover to slide, adjusting the float's height. After adjustment, the upper end of the L-shaped telescopic tube is connected to the output end of an air compressor. When the hydraulic rod is activated to flip the steel gate, the hollow tube enters the water. Then, the air compressor is activated, causing compressed air to be released from the outlet pipe. Using this structure, by rotating the threaded screw to slide the float, the depth of the hollow tube in the water is adjusted. Simultaneously, the hollow tube creates an unfrozen water zone near the steel gate, thus achieving an anti-freezing effect on the steel gate. Its structure is relatively simple, thereby improving the maintenance efficiency of the anti-freezing device.
[0012] This invention utilizes a scraping assembly, including a bidirectional motor. Activating the bidirectional motor rotates the positive and negative lead screws at both ends, which in turn rotate the threaded connecting ring on its outer surface. This causes the connecting ring and the L-shaped connecting rod to slide, thereby causing the scraper strips to slide against one side of the outer surface of the steel gate. Using this structure, by activating the bidirectional motor and driving the two scraper strips to reciprocate against one side of the outer surface of the steel gate, the scraping of the steel gate is achieved. This prevents water vapor on the steel gate surface from freezing in cold weather, further protecting the steel gate and effectively extending its service life. Attached Figure Description

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0021] As attached Figure 1 To be continued Figure 5This utility model provides a hydraulic dam gate anti-icing device, including a steel gate 1, an anti-icing component 2 on one side of the steel gate 1, a scraper component 3 on one side of the anti-icing component 2, a U-shaped frame 4 symmetrically fixedly installed on the outer surface of one side of the steel gate 1, a hydraulic rod 5 rotatably connected to the inner surface of the U-shaped frame 4, a mounting base 6 rotatably connected to one end of the hydraulic rod 5, a protective cover 7 fixedly installed in the middle of the outer surface of one side of the steel gate 1, and fixing blocks 8 symmetrically fixedly installed on both sides of the protective cover 7.
[0022] The anti-freezing component 2 includes an L-shaped telescopic tube 21. A hollow tube 22 is fixedly installed at one end of the L-shaped telescopic tube 21. An air outlet tube 23 is fixedly connected to the outer surface of the hollow tube 22. L-shaped fixing rods 24 are symmetrically and rotatably connected to both ends of the hollow tube 22. A float plate 25 is slidably installed on the outer surface of the L-shaped fixing rod 24. A threaded screw 26 is threadedly connected to the middle of the inner wall of the float plate 25. A knob 27 is fixedly installed on the outer surface of the upper end of the threaded screw 26.
[0023] Among them, the L-shaped telescopic tube 21 is fixedly installed in the middle of the inner wall of the steel gate 1, and the threaded rod 26 is rotatably connected to the inner wall of the L-shaped fixed rod 24;
[0024] By rotating the threaded screw 26 to drive the float 25 to slide, the depth of the hollow tube 22 in the water is adjusted. At the same time, the hollow tube 22 forms an unfrozen water zone near the steel gate 1, thereby achieving the antifreeze effect of the steel gate 1. Its structure is relatively simple, which improves the maintenance efficiency of the antifreeze device.
[0025] The scraper assembly 3 includes a bidirectional motor 31. A positive and negative lead screw 32 is fixedly installed on the outer surface of the output end of the bidirectional motor 31. A connecting ring 33 is threaded onto the outer surface of the positive and negative lead screw 32. An L-shaped connecting rod 34 is fixedly installed on one side of the outer surface of the connecting ring 33. A fixing ring 35 is fixedly installed on the upper outer surface of the L-shaped connecting rod 34. A scraper 36 is fixedly installed on one side of the outer surface of the fixing ring 35. The bidirectional motor 31 is fixedly installed on one side of the outer surface of the steel gate 1, located inside the protective cover 7. The positive and negative lead screw 32 is rotatably connected to one side of the inner wall of the fixing block 8. The L-shaped connecting rod 34 slides on the inner wall of the steel gate 1, and the scraper 36 slides on one side of the outer surface of the steel gate 1.
[0026] The bidirectional motor 31 drives two scraper blades 36 to reciprocate against one side of the outer surface of the steel gate 1, thus achieving the scraping work of the steel gate 1. This avoids the water vapor on the surface of the steel gate 1 from freezing in cold weather, further protecting the steel gate 1 and effectively improving its service life.
[0027] One end of the L-shaped telescopic tube 21 is fixedly connected to the output end of the air compressor, and the float 25 always floats horizontally on the water surface.
[0028] There are two scraper bars 36, and the two scraper bars 36 reciprocate relative to each other on one side of the outer surface of the steel gate 1.
[0029] The working process of this utility model is as follows:
[0030] First, according to environmental requirements, turn knob 27 to rotate threaded screw 26. The rotation of threaded screw 26 causes the float 25, threaded to the outer surface of the protective cover 7, to slide, adjusting the height of float 25. After adjustment, connect the upper end of L-shaped telescopic pipe 21 to the output end of the air compressor. When the hydraulic rod 5 is activated, causing the steel gate 1 to flip, the hollow pipe 22 enters the water. Then, the air compressor is activated, causing compressed air to be released from the air outlet pipe 23, thus adjusting the water depth of the hollow pipe 22. Simultaneously, the hollow pipe 22 creates an unfrozen water band near the steel gate 1. The steel gate 1 achieves antifreeze protection with a relatively simple structure, thereby improving the maintenance efficiency of the antifreeze device. Then, the bidirectional motor 31 is started to drive the positive and negative lead screws 32 at both ends to rotate. The rotation of the positive and negative lead screws 32 drives the connecting ring 33 with its outer surface threaded to rotate, thereby driving the connecting ring 33 and the L-shaped connecting rod 34 to slide. This causes the scraper 36 to slide back and forth against one side of the outer surface of the steel gate 1, realizing the scraping work of the steel gate 1. This avoids the water vapor on the surface of the steel gate 1 from freezing in cold weather, further protecting the steel gate 1 and effectively improving its service life.
