Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a sealed cast iron gate inlaid with copper. Background Technology

[0002] In the field of water conservancy engineering, sealed cast iron copper-lined gates are key equipment for controlling the opening and closing of water flow channels, regulating flow, and blocking water flow. They are widely used in hydropower stations, irrigation canals, sewage treatment plants, urban water supply and drainage networks, and other scenarios. Their core function relies on the reliable sealing performance between the gate body and the frame, as well as the ability to withstand silt and impurities during long-term use, so as to ensure the stable operation of water conservancy systems and the efficient regulation of water resources.

[0003] Traditional sealed cast iron copper-lined sluice gates typically have a frame groove on the inner side of the frame for guiding the sliding of the gate body. Impurities such as mud, silt, and stones carried by the water flow easily accumulate in the frame groove, especially in the horizontal section of the frame groove. Over time, this accumulation forms a hard sediment layer. When the gate body falls and closes, the sediment layer will prevent the gate body from tightly fitting the sealing surface of the frame groove, resulting in a sealing gap and causing water leakage. At the same time, the sediment can also scratch the gate body or sealing surface, accelerate the wear of sealing components, and shorten the service life of the gate.

[0004] Therefore, it is necessary to provide a new type of sealed cast iron copper-lined gate to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sealed cast iron gate inlaid with copper.

[0006] The sealed cast iron copper-lined gate provided by this utility model includes a frame, and the inner side wall of the frame is provided with a U-shaped frame groove, and a sand discharge component is provided in the frame groove.

[0007] The sand discharge assembly includes a trough elastic airbag, which is installed in the frame groove of the horizontal section of the frame, and the trough elastic airbag is connected to an elastic telescopic airbag for inflating the trough elastic airbag.

[0008] The frame is fitted with a slidingly connected door, and the door is fitted with an abutment plate for compressing the elastic telescopic airbag.

[0009] Preferably, a cover plate is fixedly installed on the top of the frame groove on both sides of the vertical section of the frame, and the frame groove with the cover plate constitutes an installation chamber, and the elastic telescopic airbag is installed in the installation chamber.

[0010] Preferably, the top surface of the elastic telescopic airbag is fixedly connected to the inner top wall of the installation chamber, and a metal air guide tube is fixedly installed on the elastic telescopic airbag, with the other end of the metal air guide tube fixedly connected to the air inlet of the filling elastic airbag.

[0011] Preferably, the lower surface of the filling elastic airbag is fixedly connected to the bottom wall of the frame groove in the horizontal section.

[0012] Preferably, side sliding sleeves are fixedly installed on both sides of the door body, and the side sliding sleeves are sleeved on the metal air guide pipe and slidably connected to the metal air guide pipe, and the inner plate surface of the side sliding sleeve abuts against the inner groove wall of the vertical section frame groove.

[0013] Preferably, the abutting sleeve is fixedly installed on the side sliding sleeve, and the abutting sleeve is sleeved on the metal air guide pipe and slidably connected to the metal air guide pipe.

[0014] Preferably, the door body is equipped with a rotatably connected threaded rod.

[0015] Preferably, fixed side plates are fixedly installed on both sides of the frame.

[0016] Preferably, the elastic expansion force of the elastic expansion airbag is much greater than that of the elastic expansion force of the grooved elastic airbag.

[0017] Preferably, the back of the frame has a sand discharge port that is flush with the bottom plate of the frame, and the sand discharge port is located at the bottom of the vertical section of the frame groove.

[0018] Compared with related technologies, the sealed cast iron gate with copper inlay provided by this utility model has the following beneficial effects:

[0019] 1. When the door is fully closed, the bottom of the door falls into the frame groove of the horizontal section. At this time, the groove filling elastic airbag is fully compressed, so the groove filling elastic airbag fits tightly against the bottom of the door and the inner wall of the frame groove, forming an elastic sealing pad effect. Combined with the rigid sealing surface of cast iron inlaid with copper, it forms a double sealing structure. Compared with the traditional single seal, this design can effectively buffer the impact force when the door is closed. At the same time, through the elastic compensation of the groove filling elastic airbag, it can adapt to the small processing errors or wear of the frame groove, significantly improving the sealing accuracy and long-term stability.

[0020] 2. In this utility model, when the door rises, it presses against the sleeve plate to compress the elastic telescopic airbag, thereby compressing the elastic telescopic airbag. At the same time, the gas inside the elastic telescopic airbag flows through the metal air guide pipe to the filling elastic airbag. Therefore, the filling elastic airbag expands and quickly fills the horizontal section of the frame groove, preventing mud and sand from falling into the horizontal section of the frame groove. Furthermore, the expanded filling elastic airbag can completely squeeze out the mud, sand, and silt remaining in the frame groove and discharge them with the water flow, realizing automatic cleaning of the frame groove and preventing the accumulation of silt from obstructing the door closure, thus ensuring the reliability of the seal from the source.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5 The present invention provides a sealed cast iron copper-lined gate, which includes a frame 1, a sand discharge assembly 2, and a gate body 3.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 The frame 1 has fixed side plates 12 fixedly installed on both sides of its side walls, and the inner side wall of the frame 1 has a U-shaped frame groove 1a. The frame 1 is equipped with a sliding door 3, and the door 3 has a sliding sleeve plate 31 fixedly installed on both sides of its side walls. The inner surface of the sliding sleeve plate 31 abuts against the inner groove wall of the vertical section of the frame groove 1a. The door 3 is equipped with a rotatably connected threaded rod 4.

[0031] It should be noted that: the frame 1 is fixedly installed on the wall of the water passage using the fixed side plate 12, and then the hoist for driving the threaded rod 4 to rise and fall is installed on the top. When the hoist is working, the output shaft drives the threaded rod 4 to rotate, and the threaded rod 4 passes through a fixed non-rotating nut (this nut is installed on the hoist or frame). Since the side sliding sleeve 31 on the gate body 3 is inserted into the inner groove wall of the frame groove 1a, the gate body 3 can be raised and lowered.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 5 The frame groove 1a is equipped with a sand discharge assembly 2, which includes a filling elastic airbag 21. The filling elastic airbag 21 is installed in the frame groove 1a of the horizontal section of the frame 1, and the lower surface of the filling elastic airbag 21 is fixedly connected to the bottom wall of the frame groove 1a of the horizontal section. The filling elastic airbag 21 is connected to an elastic telescopic airbag 22 for inflating the filling elastic airbag 21. Specifically, a cover plate 11 is fixedly installed on the top of the frame groove 1a of the vertical sections on both sides of the frame 1, and is provided with The frame groove 1a of the cover plate 11 forms an installation chamber 11a. The elastic telescopic airbag 22 is disposed in the installation chamber 11a. The top surface of the elastic telescopic airbag 22 is fixedly connected to the inner top wall of the installation chamber 11a. A metal air guide tube 23 is fixedly installed on the elastic telescopic airbag 22. The other end of the metal air guide tube 23 is fixedly connected to the air inlet of the filling elastic airbag 21. The elastic telescopic force of the elastic telescopic airbag 22 is much greater than the elastic telescopic force of the filling elastic airbag 21.

[0033] The door body 3 is equipped with an abutting sleeve 32 for compressing the elastic telescopic airbag 22. The abutting sleeve 32 is fixedly installed on the side sliding sleeve 31, and the abutting sleeve 32 is sleeved on the metal air guide tube 23 and slidably connected to the metal air guide tube 23.

[0034] It should be noted that when the door 3 falls, the bottom of the door 3 gradually slides into the horizontal section of the frame groove 1a and presses against the filling elastic airbag 21, thereby compressing and contracting the filling elastic airbag 21. At this time, the gas in the filling elastic airbag 21 flows into the elastic telescopic airbag 22 through the metal air guide tube 23. When the door 3 falls completely, the bottom of the door 3 falls into the horizontal section of the frame groove 1a. At this time, the filling elastic airbag 21 is fully compressed, so the filling elastic airbag 21 fits tightly against the bottom of the door 3 and the inner wall of the frame groove 1a, forming an elastic sealing pad effect. Combined with the rigid sealing surface of cast iron inlaid with copper, it forms a double sealing structure. Compared with the traditional single seal, this design can effectively buffer the impact force when the door 3 closes. At the same time, through the elastic compensation of the filling elastic airbag 21, it can adapt to the small processing errors or wear of the frame groove 1a, significantly improving the sealing accuracy and long-term stability.

[0035] When the door 3 rises, it presses against the sleeve plate 32 to compress the elastic telescopic airbag 22, thereby compressing the elastic telescopic airbag 22. At the same time, the gas in the elastic telescopic airbag 22 flows through the metal air guide pipe 23 to the filling elastic airbag 21. Therefore, the filling elastic airbag 21 expands and quickly fills the horizontal section of the frame groove 1a, preventing mud and sand from falling into the horizontal section of the frame groove 1a. Furthermore, the expanded filling elastic airbag 21 can completely squeeze out the mud, sand, and silt remaining in the frame groove 1a and discharge them with the water flow, realizing the automatic cleaning of the frame groove 1a and preventing the accumulation of silt from hindering the closure of the door 3, thus ensuring the reliability of the seal from the source.

[0036] The side sliding sleeve 31 is sleeved on the metal air guide pipe 23 and slidably connected to the metal air guide pipe 23, so as to avoid the metal air guide pipe 23 affecting the sliding of the side sliding sleeve 31 in the frame groove 1a.

[0037] In addition, a sand discharge port 1b is provided on the back of the frame 1, which is flush with the bottom plate of the frame 1, and the sand discharge port 1b is located at the bottom of the vertical section of the frame groove 1a. Therefore, the mud and sand falling from the vertical part of the frame groove 1a can be discharged through the sand discharge port 1b.

[0038] The materials used for the filling elastic airbag 21 and the elastic telescopic airbag 22 are fluororubber or silicone rubber composite materials with stronger weather resistance and corrosion resistance. At the same time, a polytetrafluoroethylene coating is applied to the surface of the airbag to further reduce the impact of mud and sand adhesion and water corrosion.

[0039] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
