Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy construction technology, specifically a novel waterproof structure for water conservancy construction. Background Technology
[0002] Water conservancy construction refers to the process of constructing, renovating, or repairing water conservancy facilities using various construction methods and machinery and equipment according to the water conservancy project design plan. During water conservancy construction, water pipes are important components for transporting water resources. Therefore, waterproof structures are needed to waterproof the connection points of two water pipes.
[0003] For example, a novel waterproof structure for water conservancy construction, authorized by announcement number CN222864405U, includes a sleeve, a sliding sleeve slidably installed inside the sleeve, a shock-absorbing rubber pad and a fixing clamp installed inside the sliding sleeve, and a first bolt installed on the outer side of the fixing clamp; although the above document can reduce the amplitude of movement and swing of the two water pipes, it can effectively prevent gaps from appearing at their connection, thus improving the overall stability and sealing of the device;
[0004] However, when replacing the sealing ring inside the sleeve, workers have to disassemble the sleeve and the sliding sleeve to expose the sealing ring for replacement. After replacement, the sleeve and the sliding sleeve need to be re-secured, resulting in multiple disassembly and reassembly operations. This makes the process cumbersome and time-consuming, leading some to avoid replacing the sealing ring inside the waterproof structure. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a novel waterproof structure for hydraulic construction, which solves the problem that when replacing the sealing ring inside the sleeve, multiple disassemblies and reassemblies between the sleeve and the sliding sleeve are required, resulting in cumbersome operation and long replacement time, thus eliminating the need to replace the sealing ring inside the waterproof structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel waterproof structure for water conservancy construction, comprising a water pipe, a connecting sleeve inserted into the outer wall of the water pipe, a connecting ring fixedly connected to the end of the connecting sleeve, a fixing ring fixedly connected to the outer wall of the water pipe near the connecting ring, and a replacement mechanism provided inside the connecting sleeve; the replacement mechanism includes a first clamp, a second clamp, a first connecting ear, a second connecting ear, a second bolt, and a sealing ring; the outer wall of the first clamp is inserted into the inner wall of the connecting sleeve, the second clamp is inserted into the lower part of the connecting sleeve, the first clamp and the second clamp are respectively fixedly connected to the front and back of the first clamp and the second clamp, the first connecting ear and the second connecting ear are fixedly connected by the second bolt, and the inner wall of the first clamp and the second clamp are respectively fixedly connected to the inner wall of the second clamp, the inner wall of the sealing ring being attached to the outer end of the water pipe.
[0007] Preferably, the side walls of the first clamp and the second clamp are respectively fixedly connected with rubber strips, and the outer wall of the rubber strips is attached to the inner wall of the connecting sleeve.
[0008] Preferably, the first clamp and the second clamp are respectively provided with limiting mechanisms on their exteriors; the limiting mechanism includes a limiting piece and a limiting groove; the limiting piece is fixed to the outer wall of the first clamp and the second clamp respectively, the outer wall of the connecting sleeve is provided with a limiting groove, and the outer wall of the limiting piece is inserted into the inner wall of the limiting groove.
[0009] Preferably, the inner walls of the connecting ring and the fixing ring are respectively penetrated by a first bolt, and the outer wall of the first bolt is threaded with a nut.
[0010] Preferably, a protrusion is fixedly connected to the side wall of the connecting ring, and a groove is fixedly connected to the side wall of the fixing ring, with the outer wall of the protrusion inserted into the inner wall of the groove.
[0011] Beneficial effects
[0012] This utility model provides a novel waterproof structure for hydraulic construction. It has the following advantages: This novel waterproof structure for hydraulic construction, through the cooperation of a first clamp, a second clamp, a first connecting ear, a second connecting ear, a second bolt, and a sealing ring, enables modular replacement of the rubber ring. This solves the problem that replacing the sealing ring inside the sleeve requires multiple disassemblies and reassemblies between the sleeve and the sliding sleeve, resulting in cumbersome operation and long replacement time, thus avoiding the need to replace the sealing ring inside the waterproof structure.
[0013] The cooperation between the limiting plate and the limiting groove enables the first and second clamps to be limited, preventing axial rotation of the first and second clamps. This solves the problem that when water resources are transported through water pipes, slight vibrations may occur, and since there is no limiting structure between the first and second clamps and the connecting sleeve, the first and second clamps may rotate when the water pipe vibrates.

[0020] 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.
[0021] When replacing the sealing ring inside the sleeve, the sleeve and the sliding sleeve need to be disassembled and reassembled multiple times, which makes the operation cumbersome and the replacement time long. Therefore, the sealing ring inside the waterproof structure is not replaced.
[0022] In view of this, the present invention provides a novel waterproof structure for water conservancy construction. Through the cooperation between the first clamp, the second clamp, the first connecting ear, the second connecting ear, the second bolt, and the sealing ring, the rubber ring can be replaced in a modular manner. This solves the problem that when replacing the sealing ring inside the sleeve, the sleeve and the sliding sleeve need to be disassembled and reassembled multiple times, which makes the operation cumbersome and the replacement time long. Therefore, the sealing ring inside the waterproof structure does not need to be replaced.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.
[0024] Example 1, by Figure 1-5It is understood that the novel waterproof structure for water conservancy construction in this case includes a water pipe 1, a connecting sleeve 2 inserted into the outer wall of the water pipe 1, a connecting ring 3 fixedly connected to the end of the connecting sleeve 2, a fixing ring 4 fixedly connected to the outer wall of the water pipe 1 near the connecting ring 3, and a replacement mechanism provided inside the connecting sleeve 2; the replacement mechanism includes a first clamp 9, a second clamp 10, a first connecting ear 11, a second connecting ear 12, a second bolt 13, and a sealing ring 14; the outer wall of the first clamp 9 is inserted into the inner wall of the connecting sleeve 2, the second clamp 10 is inserted into the lower part of the connecting sleeve 2, the first connecting ear 11 and the second connecting ear 12 are fixedly connected to the front and back of the first clamp 9 and the second clamp 10 respectively, the first connecting ear 11 and the second connecting ear 12 are fixedly connected by the second bolt 13, and the sealing ring 14 is fixedly connected to the inner wall of the first clamp 9 and the inner wall of the second clamp 10 respectively, the inner wall of the sealing ring 14 is attached to the outer end of the water pipe 1;
[0025] In the specific implementation process, it is worth noting that when waterproofing the connection point of the two water pipes 1, the workers insert the two water pipes 1 into the connecting sleeves 2 respectively. The water pipes 1 drive the connecting ring 3 to move, thereby causing the connecting ring 3 to contact the fixing ring 4 and connect them together. At this time, the sealing ring 14 contacts the outer wall of the connection point of the two water pipes 1, thus preventing water leakage at the connection point of the two water pipes 1. The sealing ring 14 can be made of EPDM rubber, and the second bolt 13 is made of high-strength alloy steel (such as galvanized or stainless steel of grade 8.8 or 10.9 carbon steel for corrosion-resistant environments), providing sufficient pre-tightening force to ensure that all components are tightly connected and resist water pressure, vibration, etc. For loosening, the first clamp 9 and the second clamp 10 should preferably be made of stainless steel (such as 304 stainless steel, which balances strength and corrosion resistance). High-strength alloy structural steel (such as 45 steel after quenching and tempering to improve strength) can also be used. The first clamp 9 and the second clamp 10 need to have certain strength and toughness to withstand the pre-tightening force of the second bolt 13 and the water flow pressure when clamping the water pipe 1 and sealing, so as to avoid deformation and failure. The sealing ring 14 can be connected to the inner wall of the first clamp 9 and the second clamp 10 through interference fit. After installation, it will be subjected to the clamping force of the first clamp 9 and the second clamp 10 and the water flow pressure, and will continue to maintain elastic deformation to dynamically adapt to the small displacement between the water pipe 1 and the connecting sleeve 2, so as to ensure the reliability of the seal.
[0026] When the sealing ring 8 needs to be replaced, the worker uses a tool to rotate the second bolt 13 to unscrew the second connecting ear 12, thereby releasing the fixation between the first clamp 9 and the second clamp 10. Then, the worker removes the first clamp 9 and the second clamp 10 from the connecting sleeve 2, thereby disassembling the sealing ring 14 and replacing it. After the replacement is completed, the worker puts the first clamp 9 and the second clamp 10 back into the connecting sleeve 2. Finally, the worker rotates the second bolt 13 again to fix the first clamp 9 and the second clamp 10 back onto the connecting sleeve 2, thus realizing the modular replacement of the rubber ring 14.
[0027] Furthermore, rubber strips 15 are fixedly connected to the side walls of the first clamp 9 and the second clamp 10 respectively, and the outer wall of the rubber strips 15 is attached to the inner wall of the connecting sleeve 2.
[0028] In the specific implementation process, it is worth noting that the rubber strip 15 is made of nitrile rubber, the fixing method of the rubber strip 15 is the same as above, and there are two rubber strips 15. The rubber strip 15 increases the sealing between the first clamp 9 and the second clamp 10 and the connecting sleeve 2, so as to prevent external dust and moisture from entering between the connecting sleeve 2 and the water pipe 1.
[0029] Furthermore, the first clamp 9 and the second clamp 10 are respectively provided with limiting mechanisms on their exteriors; the limiting mechanisms include limiting pieces 16 and limiting grooves 17; the limiting pieces 16 are respectively fixed to the outer walls of the first clamp 9 and the second clamp 10, and the outer wall of the connecting sleeve 2 is provided with limiting grooves 17, and the outer wall of the limiting pieces 16 is inserted into the inner wall of the limiting grooves 17.
[0030] In the specific implementation process, it is worth noting that when the first clamp 9 and the second clamp 10 are put back into the connecting sleeve 2, the first clamp 9 and the second clamp 10 drive the limiting piece 16 to move, insert the limiting piece 16 into the limiting groove 17, thereby limiting the first clamp 9 and the second clamp 10 and preventing the first clamp 9 and the second clamp 10 from rotating axially.
[0031] Example 2, by Figure 1 , 2 As can be seen from 4, the inner walls of the connecting ring 3 and the fixing ring 4 are respectively penetrated by the first bolt 8, and the outer wall of the first bolt 8 is threaded with a nut 7.
[0032] In the specific implementation process, it is worth noting that the first bolt 8 and nut 7 are made of high-strength alloy steel (such as galvanized or stainless steel of grade 8.8 or 10.9 carbon steel for corrosion-resistant environments) to provide sufficient preload force to ensure that the connection of each component is tight and to resist loosening caused by water flow pressure, vibration, etc. When fixing the water pipe 1 and the connecting sleeve 2 together, the worker moves the first bolt 8 and passes it through the connecting ring 3 and the fixing ring 4. Finally, the worker rotates the nut 7 and rotates it onto the first bolt 8 to fix the connecting ring 3 and the fixing ring 4 together, thereby fixing the water pipe 1 and the connecting sleeve 2 together.
[0033] Furthermore, a protrusion 6 is fixedly connected to the side wall of the connecting ring 3, and a groove 5 is fixedly connected to the side wall of the fixing ring 4, with the outer wall of the protrusion 6 inserted into the inner wall of the groove 5.
[0034] In the specific implementation process, it is worth noting that before the connecting ring 3 and the fixing ring 4 are fixed, the worker connects the sleeve 2. The connecting sleeve 2 drives the fixing ring 4 to move, and the fixing ring 4 drives the groove 5 to move, thereby inserting the protrusion 6 on the connecting ring 3 into the groove 5, so as to achieve positioning between the connecting ring 3 and the fixing ring 4.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
