Description

Technical Field

[0001] This utility model mainly relates to the field of water conservancy engineering construction equipment, specifically a water-stopping device for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and underground water resources and the environment. During the construction of water conservancy projects, it is often necessary to install water-stop gates at the ports of the pipelines laid to facilitate water shut-off when needed. However, existing water-stop gates have the following problems: they are inconvenient to install, and their opening and closing are unstable. The inconvenience of closing and opening / closing the gates makes the entire gate extremely unstable during use. Existing water-stop gates at the ports of water conservancy pipelines are generally fixed to the ports by drilling holes in the outer perimeter of the water conservancy pipeline and fixing the gates to the ports with bolts or by welding, which can cause a certain degree of damage to the pipe ports. Therefore, a fixing method that will not damage the pipe ports is needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a water-stopping device for water conservancy engineering construction. Its main advantages are: by installing a sleeve at the pipe end and a movable fixing plate inside the sleeve (which can be moved by bolts), the fixing plate expands outwards to abut against the inside of the pipe. A spring device is further fitted onto the bolts to enhance the abutment force. This method of fixing the device to the pipe end allows for water-stopping without damaging the pipe and is applicable to pipes of varying thicknesses. Furthermore, openable baffles are installed on both sides of the front of the sleeve to block water flow and are easily opened. A threaded block at the front of the sleeve engages with a threaded post on the baffle to fix the baffle to the front of the sleeve, sealing the pipe. A pin is threaded to one side of the threaded post, allowing the threaded post to rotate and simultaneously move the pin, further securing the baffles on both sides and improving the device's water-stopping performance.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A water-stopping device for water conservancy construction includes a sleeve. Several bolted tubes are fixedly inserted around the outer periphery of the sleeve in pairs, equidistantly spaced around the outer circumference. A sliding column sleeve corresponding to the position of the bolted tubes is fixedly installed inside the sleeve in pairs. Each sliding column sleeve has a sliding column inside it, which is slidably connected to the sliding column. A limiting plate is fixedly installed at the front of each sliding column. A movable fixing plate is fixedly installed on one side of the sliding column inside each set of sliding column sleeves. A bolted tube is fixedly installed at a position corresponding to the bolted tubes in each set of sliding column sleeves. A bolt rod is inserted through the bolted tube and its corresponding bolted tube. A nut is fitted onto the upper part of the bolt rod, threaded into it, and a spring is fitted onto the lower part of the bolt rod, abutting against the bottom of the bolted tube.

[0006] Furthermore, baffle support plates are fixedly provided on both sides of the sleeve, and baffle rotating tubes are fixedly provided at the upper and lower ends of the baffle support plates. Rotating shaft columns are provided inside the rotating tubes on both sides and are rotatably connected to them. A connecting plate is fixedly provided on the inner side of the rotating shaft column, and a baffle is fixedly provided at the end of the connecting plate. A sealing strip is fixedly provided around the inner side of the baffle.

[0007] Furthermore, a fixing bolt support box is fixedly provided at the front of the baffle. A fixing bolt hole is opened at the front of the fixing bolt support box, penetrating the fixing bolt support box and the baffle. Fixing bolt block support plates are fixedly provided on both sides of the front of the sleeve. Fixing bolt blocks are fixedly provided at the front of the fixing bolt block support plates on both sides. Fixing threaded holes are opened at the corresponding positions of the fixing bolt blocks and the fixing bolt holes. A threaded post is rotatably connected to the fixing bolt holes and penetrates the sleeve. The threaded post can be threadedly engaged with the fixing threaded hole. A rotating wheel is fixedly provided at the outer end of the threaded post.

[0008] Furthermore, a gear sleeve is fitted on one side of the threaded post, and gear teeth are fixedly provided on the outer periphery of the gear sleeve. A pin is provided inside the fixing bolt support box and is slidably connected to it. The pin has a toothed groove densely provided on one side, and the toothed groove can mesh with the gear teeth.

[0009] Compared with the existing technology, the beneficial effects of this utility model are:

[0010] 1. By installing a sleeve at the pipe end and a movable fixing plate inside the sleeve, the fixing plate expands outward to abut against the inside of the pipe. A spring device is further installed on the bolt to enhance the abutment force. In this way, the device is fixed to the pipe end, which can seal the pipe end without damaging the pipe and achieve a water-stopping effect. The movable fixing plate makes the device suitable for fixing pipes of different thicknesses and further performing water-stopping operations.

[0011] 2. Openable baffles are installed on both sides of the front of the sleeve to block water flow and can be easily opened. The baffles are fixed to the front of the sleeve by threaded blocks that are threaded into the threaded posts on the baffles to seal the pipeline. Furthermore, a pin is installed on one side of the threaded post that is threaded into it, so that when the threaded post is rotated and fixed, it drives the pin to move and further fix the baffles on both sides, thereby further improving the water-stopping performance of the device.

[0019] Example: A water-stopping device for water conservancy engineering construction

[0020] like Figure 1-5 As shown, a water-stopping device for water conservancy engineering construction has the following specific structure:

[0021] A water-stopping device for water conservancy construction includes a sleeve 1 for sealing the water supply pipeline by fixing it to the outer side of the end of the pipeline. Several bolted tubes 2 are fixedly inserted around the outer periphery of the sleeve 1, arranged in pairs at equal intervals around the circumference. A sliding column sleeve 3, corresponding to the position of the bolted tubes 2, is fixedly installed inside the sleeve 1, allowing a movable fixing plate 6 to slide within the sliding column sleeve 3 via the sliding column 4. The sliding column sleeve 3 is arranged in pairs, with a sliding column 4 slidably connected inside each sliding column sleeve 3. A limiting plate 5 is fixedly installed at the front of each sliding column 4. A sliding guide plate 5 is fixedly installed on one side of each sliding column 4 inside the sliding column sleeve 3. A movable fixing plate 6 is provided, and a bolt tube 7 is fixed at a position corresponding to the bolt tube 1 2. A bolt rod 8 is provided through the bolt tube 2 7 and the corresponding bolt tube 1 2. The bolt rod 8 is used to connect the movable fixing plate 6 and the sleeve 1. A nut sleeve 9 is fitted on the upper part of the bolt rod 8 and threadedly engages with it. By rotating the nut sleeve 9, the bolt rod 8 moves outward, thereby driving the movable fixing plate 6 to move outward, so that the movable fixing plate 6 can abut against the inner side of the water supply pipe, thereby fixing the device at the end of the water supply pipe. A spring 10 is fitted on the lower part of the bolt rod 8 and abuts against the bottom of the bolt tube 2 7. The spring 10 further generates elastic force on the movable fixing plate 6 to strengthen its abutment force.

[0022] The sleeve 1 is fixedly provided with baffle support plates 11 on both sides. The baffle support plates 11 are fixedly provided with baffle rotating tubes 12 at the top and bottom. The baffle rotating tubes 12 on both sides are provided with rotating shaft columns 13 and rotatably connected to them. The rotating shaft columns 13 are fixedly provided with connecting plates 14 on the inner side. The connecting plates 14 are fixedly provided with baffles 15 at the end. The baffles 15 are connected to the rotating shaft columns 13 through the connecting plates 14, so that the baffles 15 can rotate around the baffle rotating tubes 12, so that the baffles 15 can open and close with the front of the sleeve 1. The inner side of the baffles 15 is fixedly provided with sealing strips 16 to further seal the sleeve 1 and improve the water-stopping effect.

[0023] A fixing bolt support box 17 is fixedly provided at the front of the baffle 15. A fixing bolt hole 18 is opened at the front of the fixing bolt support box 17, penetrating the fixing bolt support box 17 and the baffle 15. Fixing bolt block support plates 19 are fixedly provided on both sides of the front of the sleeve 1. Fixing bolt blocks 20 are fixedly provided at the front of the fixing bolt block support plates 19 on both sides. Fixing bolt blocks 20 have fixing threaded holes 21 at positions corresponding to the fixing bolt holes 18. A threaded post 22 is rotatably connected to the fixing bolt hole 18 and the fixing bolt block 22. The threaded post 22 can be threadedly engaged with the fixing threaded hole 21. A rotating wheel 23 is fixedly provided at the outer end of the threaded post 22. The rotating wheel 23 drives the threaded post 22 to rotate, so that the threaded post 22 is threadedly engaged with the fixing threaded hole 21. The baffle 15 can be fixedly connected to the fixing bolt block 20 through the threaded post 22, so that the baffle 15 can be fixed to the front of the sleeve 1.

[0024] A gear sleeve 24 is fitted onto one side of the threaded post 22. Gear teeth 25 are fixedly provided on the outer periphery of the gear sleeve 24. A pin 26 is provided inside the fixing bolt support box 17 and is slidably connected to it. The pin 26 has a toothed groove 27 on one side, which can mesh with the gear teeth 25. The gear sleeve 24 and gear teeth 25 are fixedly provided on the outer periphery of one side of the threaded post 22. When the threaded post 22 is rotated by the rotating wheel 23, the gear sleeve 24 meshes with the pin 26, causing the pin 26 to slide inside the fixing bolt support box 17. This further causes the pin 26 to slide into the fixing bolt support box 17 on the other side, connecting the two fixing bolt support boxes 17 through the pin 26, thereby further fixing the baffles 15 on both sides.

[0025] Working principle:

[0026] In use, the sleeve 1 is fitted onto the outer periphery of the end of the water supply pipe. Rotating the nuts 9 around the outer periphery of the sleeve 1 moves the bolt rod 8 towards the outer periphery of the sleeve 1. This causes the spring 10 on the bolt rod 8 to push the bolt tube 7 and its connected movable fixing plate 6 outwards, ultimately causing the movable fixing plate 6 to fit against the inner wall of the water supply pipe, thus fixing the sleeve 1 to the end of the water supply pipe. Furthermore, openable baffles 15 are provided on both sides of the sleeve 1, and a sealing strip 16, which mates with the inner periphery of the sleeve 1, is provided at the rear of the baffles 15 for sealing and blocking water. When it is necessary to close the sleeve 1, the baffles 15 on both sides are closed first, and the rotating wheels 23 on both sides are rotated to drive the... The threaded post 22 rotates, causing it to engage with the threaded hole 21 on the fixing bolt block 20 at the front of the sleeve 1, thereby fixing the baffle 15 to the front of the sleeve 1 for sealing and water blocking. The gear sleeve 24 and the gear teeth 25 are fixed around the threaded post 22 on one side. When the threaded post 22 rotates, it engages with the tooth groove 27 on the inner side of the pin post 26, causing the pin post 26 to move within the fixing bolt support box 17. Finally, the pin post 26 moves to a stop between the fixing bolt support boxes 17 on both sides, and the baffles 15 on both sides are further fixed by the pin post 26 to prevent the threaded post 22 from falling off due to excessive water pressure.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
