Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy grid fixing device that is easy to install and disassemble. Background Technology

[0002] According to current water treatment industry standards, untreated sewage cannot be directly discharged and large suspended solids must be removed. In order to remove large suspended solids from sewage, rainwater pumping stations, and sewage treatment plant influent, to protect the normal operation of subsequent treatment facilities, and to reduce the load on other treatment facilities, hydraulic screens need to be installed in the primary treatment stage of sewage treatment plants. However, the existing hydraulic screens installed at the ends of sewage pipes will grow moss and other dirt on their surface during long-term use, requiring regular cleaning. However, the existing hydraulic screen fixing devices are not convenient for disassembly and installation, and disassembly and installation are time-consuming and labor-intensive, reducing the work efficiency of staff and failing to meet the needs of water conservancy projects.

[0003] A search revealed that patent CN201821294808.5 discloses a hydraulic grating fixing device that facilitates installation and disassembly. While this device, through the cooperation of a handle, disc, connecting rod, locking rod, locking groove, insert plate, and spring, makes disassembly and installation of the hydraulic grating convenient, saving time and effort and improving worker efficiency, thus greatly meeting the needs of hydraulic engineering projects, its complex structure, the use of higher-quality materials and more refined manufacturing processes, and the resulting increased manufacturing costs, along with higher maintenance requirements due to the greater number of components needing regular inspection, maintenance, and replacement, all contribute to the higher cost of maintaining and repairing this complex structure. This necessitates more time and specialized skills to complete these tasks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic grid fixing device that is easy to install and disassemble, thus solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A hydraulic grid fixing device that is easy to install and disassemble includes an outer frame, on which a grid plate is inserted, and the grid plate and the outer frame are connected and fixed by a fastener.

[0007] The outer side of the grating plate is provided with a limiting strip, and the outer frame is provided with a slot. The grating plate is installed in the outer frame by interlocking with the limiting strip and the slot.

[0008] The fastener is provided with a nut, the nut has a threaded rod inside, the top of the nut has a hexagonal protrusion, the outer frame has a first threaded hole, the outer side of the first threaded hole has a first threaded groove, and a first threaded post is provided between the first threaded groove and the first threaded hole. The grid plate has a second threaded hole, the grid plate has a second threaded groove located outside the second threaded hole, and a second threaded post is provided between the second threaded groove and the second threaded hole.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the second threaded hole and the first threaded hole are joined together to form a complete threaded hole.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] This design allows the grating panel and outer frame to be joined by splicing the threaded holes of the two parts into a single threaded hole, simplifying the installation process. Installers do not need to perform additional alignment or adjustment work; they simply screw the threaded rod of the fastener into this complete threaded hole. The spliced, complete threaded hole provides a larger contact area and a deeper thread engagement, thus enhancing the stability and strength of the connection. This design helps prevent the grating panel from loosening or falling off under stress during use. Connecting by splicing the two parts through threaded holes reduces the need for machining individual large threaded holes, thereby lowering manufacturing costs. Furthermore, this simplified installation process also reduces installation time and labor costs.

[0013] Furthermore, the first thread groove and the second thread groove are joined together to form a complete thread groove.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The combined threaded groove provides a larger contact area and a deeper thread path, which helps increase the friction between the nut and the threaded groove, thus enhancing the stability of the connection. This design prevents the nut from loosening due to vibration or external forces during use. By joining the two threaded grooves into a single complete threaded groove, installers can more easily screw the nut in or out. This design simplifies the installation and disassembly process and improves work efficiency.

[0016] Furthermore, the first and second threaded posts are joined together to form a complete threaded post.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The assembled threaded post can withstand greater axial and radial loads, improving the strength and stability of the entire connection structure. This design helps prevent connection failure or damage caused by external forces. The assembled threaded post provides a more precise thread fit, ensuring tightness and accuracy between connected components. This design helps reduce loosening or leakage problems caused by thread mismatch.

[0019] Furthermore, the threaded rod of the fastener is threadedly connected to the second threaded hole and the first threaded hole.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The main characteristics of threaded connections are high tightening force and strong connection. When the threaded rod of the fastener is threaded into the second and first threaded holes, a tight engagement is formed, capable of withstanding large tensile forces, shear forces, and torques, ensuring the stability and reliability of the connection. Threaded connections utilize the thread pair engagement principle, allowing for easy unscrewing under sufficient installation torque, and facilitating disassembly. This design enables easy disassembly and replacement of the connection between the grating and the outer frame, simplifying maintenance and repair.

[0022] Furthermore, the nut of the fastener is located in the first threaded groove and the second threaded groove, and the nut is threadedly connected to the first threaded post and the second threaded post.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The fit between the nut and the first and second threaded grooves, as well as the threaded connection between the nut and the first and second threaded posts, together form a robust connection structure. This multi-layered connection significantly enhances the stability of the connection, making the entire device more reliable during use. The threaded connection itself has high strength, and the threaded connection between the nut and the two threaded grooves and two threaded posts further strengthens the connection. This design allows the device to withstand greater external forces, improving its overall load-bearing capacity and safety. Because the nut is threadedly connected to the threaded grooves and threaded posts, disassembly and maintenance can be easily performed by rotating the nut. This design not only simplifies the disassembly process but also reduces maintenance costs and improves work efficiency.

[0025] This utility model provides a hydraulic grid fixing device that is easy to install and disassemble. It has the following advantages:

[0026] The grating panel can be quickly and securely installed inside the outer frame using a locking strip and slot design, eliminating the need for complicated installation steps. The fastener design makes the connection between the grating panel and the outer frame more robust, and the threaded connection allows for easy tightening or loosening, facilitating the removal and replacement of the grating panel.

[0027] The use of components such as nuts, threaded rods, first threaded post, and second threaded post forms a stable connection structure, ensuring the stability and safety of the grating within the outer frame. The threaded connection is self-locking, effectively preventing the grating from loosening or falling off due to external forces during use.

[0028] The design of the first and second threaded grooves allows the nut to fit more tightly against the outer frame and grille plate, further enhancing the stability of the connection. The hexagonal protrusion design facilitates the use of tools to tighten or loosen the nut, improving work efficiency.

[0029] Because the grating panels can be easily removed and replaced, the device is more convenient to maintain. When the grating panels are damaged or need cleaning, they can be easily removed and handled. Attached Figure Description

[0038] 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.

[0039] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0040] Example 1

[0041] A hydraulic grid fixing device that is easy to install and disassemble includes an outer frame 3, a grid plate 1 inserted into the outer frame 3, the grid plate 1 and the outer frame 3 being connected and fixed by a fastener 2, a limiting strip 104 being provided on the outer side of the grid plate 1, and a slot 303 being provided inside the outer frame 3, the grid plate 1 being installed inside the outer frame 3 by the limiting strip 104 and the slot 303 engaging with each other.

[0042] Example 2

[0043] To facilitate quick and easy connection and fixation of the grating panel 1 and the outer frame 3, for example, as shown... Figures 1 to 4As shown, the present invention also includes: a nut 203 provided in the fastener 2, a threaded rod 201 inside the nut 203, a hexagonal protrusion 202 at the top of the nut 203, a first threaded hole 302 on the outer frame 3, a first threaded groove 301 on the outer side of the first threaded hole 302, a first threaded post 304 between the first threaded groove 301 and the first threaded hole 302, and a second threaded hole 103 on the grating plate 1. The second threaded hole 103 and the first threaded hole 302 are joined together to form a complete threaded hole. This design enables the grating plate 1 and the outer frame 3 to form a complete threaded connection channel through the double threaded hole splicing technology, significantly simplifying the installation process. Installers do not need to perform tedious alignment and adjustment operations; they only need to smoothly screw the threaded rod 201 of the fastener 2 into this complete threaded channel to complete the installation. The assembled threaded holes, with their larger contact area and deeper thread engagement, effectively enhance the stability and load-bearing capacity of the connection, effectively preventing the grating plate 1 from loosening or falling off under stress. Furthermore, the double-threaded hole splicing technology reduces the processing requirements for a single large threaded hole, thus significantly reducing manufacturing costs. Simultaneously, this design simplifies the installation process, shortens the installation cycle, and reduces labor costs. The threaded rod 201 of the fastener 2 is threadedly connected to the second threaded hole 103 and the first threaded hole 302. Threaded connections are known for their high tightening force and strong connection. When the threaded rod 201 of the fastener 2 is threadedly connected to the first and second threaded holes 103, a tight engagement is formed, withstanding significant tension, shear, and torque, ensuring the stability and reliability of the connection. The threaded connection utilizes the thread pair engagement principle, allowing for easy unscrewing under sufficient installation torque, facilitating disassembly. This design allows for easy disassembly and replacement of the connection between the grating plate 1 and the outer frame 3, facilitating subsequent maintenance and repair. A second threaded groove 102 is provided on the grating plate 1 outside the second threaded hole 103. The first threaded groove 301 and the second threaded groove 102 are joined to form a complete threaded groove. This joint provides an increased contact area and an extended thread path, which helps increase the frictional resistance between the nut 203 and the threaded groove, thereby improving the stability of the connection. This design effectively prevents the nut 203 from loosening under vibration or external force. By joining the two threaded grooves into a complete threaded channel, installers can more easily screw the nut 203 in and out, simplifying the installation and disassembly process and improving work efficiency. A second threaded post 101 is provided between the second threaded groove 102 and the second threaded hole 103. The first threaded post 304 and the second threaded post 101 are joined to form a complete threaded post. This joint can withstand greater axial and radial loads, significantly improving the strength and stability of the entire connection structure. This design effectively prevents connection failure or damage caused by external forces.Meanwhile, the assembled complete threaded post provides a more precise thread fit, ensuring the tightness and accuracy between connected components. This effectively reduces loosening or leakage problems caused by thread mismatch. The nut 203 of the fastener 2 is located within the first threaded groove 301 and the second threaded groove 102, and is threadedly connected to the first threaded post 304 and the second threaded post 101. The threaded connections of the nut 203 with the first and second threaded grooves 102 and the first and second threaded posts 101 together form a robust connection system. This multi-connection method significantly enhances the stability of the connection, making the entire device more reliable during use. The threaded connection itself has high strength, and the threaded connection of the nut 203 with the two threaded grooves and the two threaded posts further enhances the strength of the connection. This design allows the device to withstand greater external forces, improving the overall load-bearing capacity and safety. Furthermore, because the nut 203 is threadedly connected to the threaded grooves and threaded posts, disassembly and maintenance can be easily performed by rotating the nut 203, simplifying the disassembly process, reducing maintenance costs, and improving work efficiency.

[0044] Working principle:

[0045] The outer side of the grating plate 1 is provided with a limiting strip 104, while the inner side of the outer frame 3 is provided with a slot 303 that matches the limiting strip 104. During installation, first align the limiting strip 104 of the grating plate 1 with the slot 303 of the outer frame 3, and gently push it in so that the limiting strip 104 and the slot 303 engage and limit each other.

[0046] The grating plate 1 has a second threaded hole 103, while the outer frame 3 has a first threaded hole 302. When the grating plate 1 is correctly installed inside the outer frame 3, the second threaded hole 103 and the first threaded hole 302 will fit together to form a complete threaded hole. The threaded rod 201 of the fastener 2 can pass through this complete threaded hole and be tightened by the nut 203. The nut 203 has threads inside that match the threaded rod 201, so the threaded rod 201 can be fixed in the threaded hole by rotating the nut 203.

[0047] To further enhance the stability of the connection, the device is also designed with a first threaded groove 301 and a second threaded groove 102. When the nut 203 is tightened, it simultaneously contacts the first threaded groove 301 and the second threaded groove 102, forming a tighter connection. In addition, the first threaded post 304 and the second threaded post 101 also serve as auxiliary connectors. They are located within the first threaded groove 301 and the second threaded groove 102, respectively. When the nut 203 is tightened, these threaded posts are compressed together, thereby increasing the strength of the connection.

[0048] To remove the grating plate 1, first use a tool (such as a wrench) to loosen the nut 203. By rotating the nut 203 counterclockwise, it can be unscrewed from the threaded rod 201.

[0049] Once the nut 203 is fully loosened, the connection between the grating plate 1 and the outer frame 3 becomes less tight. At this point, the grating plate 1 can be gently pulled out of the outer frame 3, causing its limiting strip 104 to separate from the slot 303.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
