Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a valve assembly for water conservancy engineering. Background Technology

[0002] Water conservancy projects are comprehensive engineering systems designed to regulate, utilize, and protect water resources for the benefit of human society and the ecological environment. By constructing facilities such as dams, dikes, sluices, pumping stations, canals, and reservoirs, they systematically address the problem of uneven spatial and temporal distribution of water resources, achieving multiple objectives such as flood control and drainage to protect life and property, irrigation and water supply to support agricultural production, hydropower generation to provide clean energy, navigation to promote regional connectivity, and water ecological restoration to maintain environmental balance. At the same time, they also take into account climate change, improve water quality, and promote sustainable socio-economic development, making them a key infrastructure for the harmonious coexistence of humans and nature.

[0003] Chinese patent CN222525314U discloses a valve for hydraulic engineering. This valve opens the valve by the cooperation of a main shaft and a first rope reel, which causes a first steel wire rope to move the valve upward. At the same time, the cooperation of a drive wheel, a belt, and a driven wheel causes the secondary shaft to rotate the second rope reel, which in turn causes the second steel wire rope to move the filter screen downward, thereby filtering out garbage on the water surface.

[0004] The aforementioned patent can only filter garbage on the water surface, but cannot clean it. Furthermore, the filter holes on the filter screen are easily clogged by garbage or impurities, affecting water flow. Utility Model Content

[0005] The purpose of this invention is to provide a valve assembly for water conservancy projects, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A valve assembly for hydraulic engineering includes a gate frame, a gate plate slidably mounted inside the gate frame, and a hydraulic rod mounted on the top of the gate frame, with its telescopic end connected to the gate plate. Guide slide rods are mounted on both sides of the outer surface of the gate frame, and sliding sleeves are slidably mounted on the outer surfaces of the guide slide rods. A filter basket is installed between the opposing surfaces of the two sliding sleeves. A lifting mechanism is provided on the outer side of the gate frame to drive the filter basket to move vertically up and down.

[0008] Therefore, by lifting the filter basket by the lifting mechanism, the garbage on the water surface can be lifted up using the filter basket. Then, the sliding sleeve can be removed from the guide slide rod, thereby cleaning the garbage inside the filter basket. This prevents the garbage on the water surface from gradually accumulating and affecting the water quality, and also reduces the difficulty for operators to retrieve the garbage and reduces the workload.

[0009] Furthermore, the lifting mechanism includes two brackets mounted on the upper surface of the gate frame, with a winding shaft rotatably mounted between the two brackets. A motor is mounted on the outer surface of one of the brackets, and the output shaft of the motor is connected to the winding shaft. A steel wire rope is wound around the outer surface of the winding shaft, and the end of the steel wire rope is connected to the filter basket.

[0010] Furthermore, a handle is installed on the top of the filter basket, and a hook is connected to the end of the wire rope.

[0011] Furthermore, the outer surface of the gate is provided with an outward protrusion, the surface of which is flush with the outer surface of the gate. A scraper is provided on one side of the top of the filter basket, and the scraper is in contact with the outward protrusion.

[0012] Furthermore, the inner wall of the sleeve is provided with balls, which make rolling contact with the outer surface of the guide rod.

[0013] Furthermore, a connecting plate is provided between the two supports, and a collar is installed at the end of the connecting plate, with the wire rope placed inside the collar. The inner surface of the collar is evenly distributed with bristles that come into contact with the wire rope.

[0014] Furthermore, a crossbar is installed between the two supports, and a connecting plate is slidably mounted on the outer surface of the crossbar in a horizontal direction.

[0015] Furthermore, the bottom of the filter basket has an inverted triangular structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model uses a lifting mechanism to raise the filter basket, which can be used to lift the garbage on the water surface. Then, the sliding sleeve can be removed from the guide slide rod, thereby cleaning the garbage in the filter basket, preventing the garbage on the water surface from gradually accumulating and affecting the water quality, and reducing the difficulty for operators to retrieve garbage and reducing the workload.

[0018] 2. By using the bristles, this utility model allows the wire rope to move within the collar and rub against the bristles when the winding shaft winds or releases the wire rope. This cleans algae, impurities, or garbage adhering to the surface of the wire rope, preventing it from affecting the winding process and extending its service life. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a valve assembly for hydraulic engineering, including a gate frame 1. A gate plate 101 is slidably installed inside the gate frame 1. A hydraulic rod 102 is installed on the top of the gate frame 1, and the end of the hydraulic rod 102 is connected to the gate plate 101. Guide slide rods 103 are installed on both sides of the outer surface of the gate frame 1. Sliding sleeves 104 are slidably installed on the outer surface of the guide slide rods 103. A filter basket 105 is installed between the opposing surfaces of the two sliding sleeves 104. A lifting mechanism 2 is provided on the outer side of the gate frame 1, which is used to drive the filter basket 105 to move vertically up and down.

[0027] When it is necessary to open the gate 101 to release water, the gate 101 can be lifted upward by the hydraulic rod 102. At this time, the bottom of the gate 101 is still inside the water, and the water can be discharged from the bottom of the gate 101. The garbage on the water surface will be carried by the water flow and accumulate on the surface of the gate 101. The operator can lift the filter basket 105 by the lifting mechanism 2 to lift it out of the water. The water will be discharged from the filter holes on the filter basket 105, while the garbage will be left in the filter basket 105. Then the sliding sleeve 104 can be removed from the guide slide rod 103, so that the garbage in the filter basket 105 can be cleaned, avoiding the gradual accumulation of garbage on the water surface and affecting the water quality. It also reduces the difficulty for the operator to retrieve the garbage and reduces the workload.

[0028] Preferably, the lifting mechanism 2 includes two supports 201 mounted on the upper surface of the gate frame 1, with a winding shaft 202 rotatably mounted between the two supports 201. A motor 203 is mounted on the outer surface of one of the supports 201, and the output shaft of the motor 203 is connected to the winding shaft 202. A steel wire rope 204 is wound around the outer surface of the winding shaft 202, and the end of the steel wire rope 204 is connected to the filter basket 105.

[0029] The motor 203 drives the winding shaft 202 to rotate. When the winding shaft 202 winds up the wire rope 204, it can drive the filter basket 105 to rise. When the winding shaft 202 releases the wire rope 204, it can drive the filter basket 105 to fall.

[0030] Since the guide rod 103 and the sliding sleeve 104 limit the movement of the filter basket 105, the stability of the filter basket 105 in raising and lowering can be ensured, and the filter basket 105 is prevented from shaking randomly under the influence of water flow.

[0031] Preferably, a handle 3 is installed on the top of the filter basket 105, and a hook 301 is connected to the end of the wire rope 204.

[0032] The hook 301 and handle 3 enable quick connection between the filter basket 105 and the wire rope 204. After the filter basket 105 is lifted to a high position, it is easy to remove the filter basket 105 from the wire rope 204 to clean the collected garbage.

[0033] Preferably, the outer surface of the gate 101 is provided with an outward protrusion 1011, and the surface of the outward protrusion 1011 is flush with the outer surface of the gate 101. A scraper 4 is provided on one side of the top of the filter basket 105, and the scraper 4 is in contact with the outward protrusion 1011.

[0034] When the filter basket 105 is lifted, it drives the scraper 4 to scrape off the garbage and algae and other impurities attached to the surface of the gate 101. After scraping, the garbage falls directly into the filter basket 105, which is more conducive to garbage collection and improves the cleanliness of the gate 101.

[0035] Preferably, the inner wall of the sliding sleeve 104 is provided with balls 1041, which roll in contact with the outer surface of the guide slide rod 103.

[0036] By setting the ball bearing 1041, the frictional contact between the sliding sleeve 104 and the guide slide rod 103 can be transformed into rolling contact, which reduces resistance, improves the smoothness of the lifting and lowering of the filter basket 105, and reduces the load on the motor 203 and the wire rope 204.

[0037] Preferably, a connecting plate 5 is provided between the two supports 201, and a collar 501 is installed at the end of the connecting plate 5, with the wire rope 204 disposed inside the collar 501. The inner surface of the collar 501 is evenly distributed with bristles 502 that contact the wire rope 204.

[0038] With the bristles 502 in place, when the winding shaft 202 winds up or releases the wire rope 204, the wire rope 204 moves within the collar 501 and rubs against the bristles 502, thereby cleaning algae, impurities or garbage attached to the surface of the wire rope 204, avoiding affecting the winding of the wire rope 204 and improving its service life.

[0039] Preferably, a crossbar 503 is installed between the two brackets 201, and the connecting plate 5 is slidably installed on the outer surface of the crossbar 503 in the horizontal direction.

[0040] Since the position of the wire rope 204 may change when it is wound on the winding shaft 202, the sliding connection between the connecting plate 5 and the crossbar 503 can make the bristles 502 adapt to the position change of the wire rope 204 and ensure the cleaning effect on the surface of the wire rope 204.

[0041] Preferably, the bottom of the filter basket 105 has an inverted triangular structure.

[0042] The inverted triangular structure makes it easier for the filter basket 105 to be immersed in water, and can prevent surface debris from obstructing the filter basket 105 and causing it to be unable to be immersed in water.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
