Description
Technical Field
[0001] This utility model relates to the field of pump station protection technology, and in particular to a pump station protection mechanism for water conservancy projects. Background Technology
[0002] Pumping stations in water conservancy projects are core facilities used to lift and transport water in water conservancy systems. They are applied in irrigation, drainage, and water diversion. Their working principle is to use an electric motor to drive the pump impeller to rotate, converting mechanical energy into the kinetic and potential energy of the water body, thus transporting water from a lower to a higher level. However, during operation, pumping stations are constantly affected by water erosion, silt abrasion, and corrosion. They also face the risk of impact from external foreign objects and human damage, leading to equipment failure, reduced operating efficiency, and even safety accidents. Therefore, the design and application of protective mechanisms are particularly important to ensure the stable and efficient operation of pumping stations. Water conservancy project pumping station protective mechanisms are a series of devices and structures designed to protect pumping station equipment and facilities. Their function is to resist damage from adverse external factors and ensure the normal operation of the pumping station.
[0003] Currently, the existing solution to the protection problem of pumping stations in water conservancy projects is to use traditional fixed protective structures. These structures, through fixed installation, can block some foreign objects and external interference to a certain extent, achieving basic protection for the pumping station equipment. However, due to their fixed structure, they are difficult to effectively buffer and cope with the impact of large flow rates or large foreign objects, and may deform, be damaged, or even fail. Once these protective structures are damaged, repair and replacement are difficult and require a lot of time and manpower, resulting in prolonged pumping station downtime, affecting the normal scheduling and use of water conservancy projects, and failing to meet the needs of efficient and safe operation of modern water conservancy pumping stations. Therefore, a water conservancy project pumping station protection mechanism is proposed to solve the above problems. Summary of the Invention
[0004] To overcome the above deficiencies, this utility model provides a protective mechanism for pumping stations in water conservancy projects, which aims to improve the problem that existing technologies are difficult to effectively buffer and cope with when facing large flow of water or impacts from large foreign objects, resulting in deformation, damage, or even failure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective mechanism for a water conservancy engineering pump station, comprising a base plate, side frames fixedly connected to the top left and right sides of the base plate, outer plates fixedly connected to the inner walls of the two side frames on opposite sides, buffer pads fixedly connected to the outer walls of the two outer plates on opposite sides, shock-absorbing springs fixedly connected to the adjacent outer walls of the two outer plates, a grid fixedly connected to the middle of the inner walls of the two side frames, damping fixedly connected to the outer walls of the two grids on opposite sides, inner plates fixedly connected to the adjacent inner walls of the two side frames, airbags fixedly connected to the outer walls of the two inner plates, a single top plate fixedly connected to the top of the outer walls of the two side frames, a pump station mechanism fixedly connected to the top middle of the base plate, and a passage mechanism provided on the front top of the base plate for providing a passage for maintenance personnel.
[0006] As a further description of the above technical solution:
[0007] The channel mechanism includes two side strips. The outer wall of the left side strip is fixedly connected to the outer wall of the left side frame. Multiple rotating plates are arranged between adjacent side strips, and the inner walls of each rotating plate are rotatably connected to a rotating shaft. A pulley is rotatably connected to the bottom of the right side strip. A sliding groove is formed on the top front side of the base plate. A locking plate is rotatably connected to the outer wall of the right side frame, and a locking groove is formed on the outer wall of the right side strip. As a further description of the above technical solution:
[0008] The passage mechanism also includes a revolving door, the left side of which is rotatably connected to the outer wall of the left side frame, and multiple hinges are fixedly connected to the outer wall of the revolving door, with a door handle fixedly connected to the front side of the outer wall of the revolving door.
[0009] As a further description of the above technical solution:
[0010] Each of the two side frames has two pillars fixedly connected to its bottom, and each of the multiple pillars has a support leg fixedly connected to its bottom.
[0011] As a further description of the above technical solution:
[0012] The inner walls of the multiple legs are threaded with multiple bolts, and the top of each bolt has a cross groove.
[0013] As a further description of the above technical solution:
[0014] Multiple reflective strips are fixedly connected to the outer walls of both side frames, and the same reinforcing plate is connected to the adjacent side of the outer walls of the two pillars on the same side.
[0015] As a further description of the above technical solution:
[0016] Multiple reinforcing strips are fixedly connected to the bottom of both reinforcing plates, and the bottom of each of the multiple reinforcing strips is fixedly connected to the same mounting plate.
[0017] As a further description of the above technical solution:
[0018] The top of the outer wall of the top plate is provided with multiple flow channels, and the outer wall of the door handle is rounded.
[0019] This utility model has the following beneficial effects:
[0020] 1. In this utility model, the shock-absorbing spring and the mesh are connected by the outer plate. When impacted, the shock-absorbing spring can compress and extend to buffer energy, prolong the stress time, and reduce the peak force. The mesh can disperse the impact force. The outer wall of the mesh is connected to damping, which can consume energy to suppress vibration and reduce the continuous shaking after the impact. At the same time, the outer wall of the inner plate is equipped with airbags, which can absorb energy through compression deformation to protect the pump station mechanism when the equipment vibrates or is impacted by external forces. This multi-stage buffer structure effectively buffers the vibration generated by the operation of the pump station mechanism, reduces the impact on the surrounding environment, and protects itself from excessive vibration damage.
[0021] 2. In this utility model, a rotatable locking plate is provided on the outer wall of the right side frame, and a locking groove is opened on the outer wall of the right side strip. This allows maintenance personnel to manually rotate the locking plate to disengage it from the locking groove, quickly releasing the fixed constraint of the right side strip, which facilitates subsequent operations. By providing a pulley at the bottom of the right side strip and opening a sliding groove on the top of the base plate, and by connecting multiple rotating plates to the side strip through a rotating shaft, when the right side strip is pushed, the rotating plates rotate around the rotating shaft. At the same time, the right side strip slides to the left under the guidance of the pulley and the sliding groove, thereby gradually expanding the passage space and meeting the needs of large maintenance equipment entering and exiting and personnel working.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. (Refer to the accompanying drawings.) Figure 1 Appendix Figure 3 and attached Figure 4This utility model provides an embodiment of a protective mechanism for a pumping station in a water conservancy project, comprising a base plate 1, which serves as a basic support component, providing a stable installation foundation for the entire protective mechanism and ensuring its stable installation. Side frames 3 are fixedly connected to the top left and right sides of the base plate 1. The side frames 3 form the main frame of the protective mechanism, together with the base plate 1, creating a stable three-dimensional frame structure to ensure the overall strength of the protective mechanism. Outer plates 4 are fixedly connected to the inner walls of the two side frames 3 on opposite sides. The outer plates 4 act as a protective barrier, preventing external objects from directly impacting the internal components. Buffer pads 5 are fixedly connected to the outer walls of the two outer plates 4 on opposite sides. When subjected to external impact, the buffer pads 5 absorb energy through their own deformation, reducing the impact force on the outer plates 4. Shock-absorbing springs 6 are fixedly connected to the adjacent sides of the outer walls of the two outer plates 4. The shock-absorbing springs 6 undergo elastic deformation when subjected to impact, further buffering energy, prolonging the impact time, and reducing the peak force. A mesh is fixedly connected to the middle of the inner walls of the two side frames 3. 7. The grid 7 can disperse the impact force and provide installation support for the damper 8. The outer walls of the two grids 7 are fixedly connected to the damper 8 on the side away from each other. The damper 8 suppresses vibration by consuming energy, reduces the continuous shaking caused by the impact, and improves the stability of the protective mechanism. The inner walls of the two side frames 3 are fixedly connected to the inner plates 9 on the adjacent side. The inner plates 9 are used to install the airbags 10 and play a protective and support role. The outer walls of the two inner plates 9 are fixedly connected to the airbags 10. When the equipment vibrates or is subjected to external impact, the airbags 10 absorb energy through compression deformation and protect the pump station mechanism 12 from vibration and impact. The top of the outer walls of the two side frames 3 are fixedly connected to the same top plate 11. The top plate 11 prevents objects above from falling and damaging the pump station mechanism 12 and provides top protection. The top middle of the bottom plate 1 is fixedly connected to the pump station mechanism 12, so that the protective mechanism can form all-round protection for the pump station mechanism 12. The top front side of the bottom plate 1 is provided with a channel mechanism 2. The channel mechanism 2 is used to provide a passage for maintenance personnel.
[0029] Specifically, when an external object impacts, the buffer pad 5 makes contact first, absorbing some of the energy and reducing the impact force on the outer plate 4. The outer plate 4 is connected to the grid 7 through the damping spring 6. During the impact, the damping spring 6 is compressed and extended, prolonging the stress time and reducing the peak force. The grid 7 further disperses the impact force. The damping 8 on the outer wall of the grid 7 suppresses vibration by consuming energy, reducing the continuous shaking after the impact. The airbag 10 on the outer wall of the inner plate 9 is compressed and deformed under equipment vibration or external impact, absorbing the remaining energy and protecting the pump station mechanism 12. The top plate 11 prevents objects above from falling and damaging the pump station mechanism 12. When the pump station mechanism 12 vibrates during operation, the vibration is transmitted from the bottom plate 1 to the side frame 3, and is buffered in sequence by the buffer pad 5, the damping spring 6, the damping 8 and the airbag 10, reducing the impact on the surrounding environment and protecting the pump station mechanism 12.
[0030] See attached document Figure 2 Appendix Figure 4 and attached Figure 5 The passage mechanism 2 includes two side strips 201, which provide an installation base and side support for the rotating plates 202, ensuring the overall structural stability of the passage mechanism 2. The outer wall of the left side strip 201 is fixedly connected to the outer wall of the left side frame 3, achieving a stable connection between the passage mechanism 2 and the main body of the protective mechanism, ensuring that it will not shift during use. Multiple rotating plates 202 are arranged between the two adjacent side strips 201. The rotating plates 202 form a retractable passage barrier during opening and closing, realizing the opening and closing of the passage. The system integrates multiple rotating plates 202, each with a rotating shaft 203 rotatably connected to its inner wall. The shaft 203 provides the rotating center for each plate 202, allowing it to rotate flexibly to change the channel state. A pulley 204 is rotatably connected to the bottom of the right-side strip 201. The pulley 204 engages with a sliding groove 205 to reduce friction during sliding, making the sliding smoother. A sliding groove 205 is provided on the top front side of the base plate 1, providing a sliding track for the pulley 204 and facilitating the sliding of the right-side strip 201. The mechanism serves as a guide and positioning element. A locking plate 206 is rotatably connected to the outer wall of the right side frame 3. The locking plate 206 engages with a locking groove 207 to lock the right side strip 201, ensuring stability when the passage is closed. A locking groove 207 is provided on the outer wall of the right side strip 201, which engages with the locking plate 206 to provide a locking point for the right side strip 201, preventing accidental sliding. The passage mechanism 2 also includes a revolving door 208, which provides a convenient passage for daily personnel access without requiring full opening of the telescopic mechanism. The passageway is passable. The left side of the revolving door 208 is rotatably connected to the outer wall of the left side frame 3, realizing the hinge connection between the revolving door 208 and the main body of the protective mechanism, so that it can rotate around the axis to open and close. Multiple hinges 209 are fixedly connected to the outer wall of the revolving door 208. The hinges 209 enhance the stability of the rotational connection of the revolving door 208 and ensure that the revolving door 208 will not loosen during rotation. A door handle 210 is fixedly connected to the front side of the outer wall of the revolving door 208. The door handle 210 provides a force point for the operator to easily control the opening and closing of the revolving door 208.
[0031] Specifically, when opening, the maintenance personnel first grasp the door handle 210 on the revolving door 208 and apply force around the hinge 209 as the axis to make the revolving door 208 rotate around the axis to open, providing a preliminary entry passage. Next, the locking plate 206 on the outer wall of the right side frame 3 is manually rotated to disengage it from the limiting slot of the locking groove 207 on the outer wall of the right side strip 201, releasing the fixed constraint of the right side strip 201. Then, the right side strip 201 is pushed, and the rotating plate 202 rotates around the rotating shaft 203. The bottom pulley 204 of the right side strip 201 slides and moves to the left along the top sliding groove 205 of the base plate 1. The rotating plate 202 rotates and retracts synchronously until the passage is fully opened to meet the needs of equipment and personnel entry and exit. When closing the passage, the operation is reversed to restore the passage mechanism 2 to its complete protective function and ensure the safety of the pump station equipment.
[0032] See attached document Figure 1 Appendix Figure 2 and attached Figure 3 Each of the two side frames 3 has two fixed supports 13 at its bottom. The supports 13 increase the support height between the side frames 3 and the ground, improving the overall stability and anti-overturning capability of the protective mechanism. Each of the supports 13 has a fixed foot 14 at its bottom. The foot 14 increases the contact area between the supports 13 and the ground, dispersing the pressure of the protective mechanism on the ground and preventing sinking. The inner walls of each foot 14 are threaded with multiple bolts 15, which securely connect the foot 14 to the ground, ensuring reliable installation of the protective mechanism. Each bolt 15 has a cross-shaped groove 16 at its top, facilitating tightening and loosening with a Phillips screwdriver, improving installation and maintenance efficiency. Each of the two side frames 3 has multiple reflective strips 17 fixedly connected to its outer wall. These reflective strips 17 reflect light under illumination, serving as a warning and reminding personnel of the protective mechanism's location. (The last sentence appears to be incomplete and possibly refers to a separate section.) The outer walls of each support column 13 are connected to the same reinforcing plate 18 on adjacent sides. The reinforcing plate 18 enhances the connection strength between the two support columns 13 and improves the overall stability of the support column 13 structure. Multiple reinforcing strips 19 are fixedly connected to the bottom of each of the two reinforcing plates 18. The reinforcing strips 19 further enhance the connection between the reinforcing plate 18 and the ground and improve the overall stability of the protective mechanism. The bottom of the multiple reinforcing strips 19 is fixedly connected to the same mounting plate 20. The mounting plate 20 provides an installation surface for the reinforcing strips 19 to connect with the ground, so that the reinforcing strips 19 can be fixed to the ground by bolts 15. Multiple drainage channels 21 are opened on the top of the outer wall of the top plate 11. The drainage channels 21 guide rainwater to drain quickly, prevent liquid from accumulating on the top plate 11, and avoid damage to the top plate 11 due to long-term liquid erosion. The outer wall of the door handle 210 is rounded to reduce the discomfort when people hold it and to avoid scratches caused by sharp edges.
[0033] Specifically, the combination of support column 13 and support leg 14 increases the support height and contact area, and is fixed with bolt 15 to ensure stable installation of the mechanism. The cross groove 16 design facilitates installation and disassembly, improving maintenance efficiency. The reflective strip 17 provides safety warning and reduces the risk of collision. The reinforcing plate 18, reinforcing strip 19 and mounting plate 20 enhance structural stability and improve the overall resistance to external forces. The drainage channel 21 of the top plate 11 can quickly drain rainwater, prevent the top plate 11 from being corroded and extend its service life. The smooth treatment of the door handle 210 is a detail that ensures the safety and comfort of the operator.
[0034] Working Principle: This mechanism is based on the base plate 1, forming a stable frame structure with the side frame 3 on top. When an external object impacts the protective mechanism, the buffer pad 5 first contacts and absorbs some energy, reducing the direct impact force on the outer plate 4. A damping spring 6 is fixedly connected to the adjacent side of the outer wall of the outer plate 4. The other end of the damping spring 6 is connected to the grid 7. When impacted, the damping spring 6 further buffers energy through compression and extension, prolonging the impact time and reducing the peak force. The grid 7 not only provides support but also disperses the impact force. The outer wall of the grid 7 is connected to a damper 8, which suppresses vibration by consuming energy, reducing the continuous vibration caused by the impact. An airbag 10 is fixedly connected to the outer wall of the inner plate 9. When the equipment vibrates during operation or is subjected to external impact, the airbag 10 absorbs energy through compression and deformation, further protecting the pump station mechanism 12. 1. The protective structure provides top protection to prevent objects from falling and damaging the pump station mechanism 12. The entire protective structure is set around the pump station mechanism 12 to form a complete protection system. When the pump station mechanism 12 is running, the vibration generated is transmitted to the side frame 3 through the base plate 1. After passing through the multi-level buffer structure of the buffer pad 5, shock absorber spring 6, damper 8 and airbag 10, the impact of vibration on the surrounding environment can be reduced. At the same time, the pump station mechanism 12 itself is protected from excessive vibration damage. When encountering external impact, the buffer pad 5 and shock absorber spring 6 play a role first, absorbing and dispersing most of the impact force. The remaining energy is transmitted to the grid 7 and damper 8 through the side frame 3, and is further consumed and suppressed. The airbag 10 provides the final buffer and absorption of the vibration from the inside and the remaining external impact energy, ensuring that the pump station mechanism 12 operates in a safe environment.Furthermore, when the passage needs to be opened for maintenance, the revolving door 208 is opened first. The maintenance personnel hold the door handle 210 and rotate it outward or inward around the hinge 209 as the axis. Utilizing the hinge characteristic of the hinge 209, the revolving door 208 is rotated around the axis to open. The opening of the revolving door 208 provides the maintenance personnel with a preliminary entry passage. Next, the right side strip 201 is unlocked. The maintenance personnel manually rotate the lock plate 206 to disengage it from the limiting slot of the lock groove 207, releasing the fixed constraint of the right side strip 201. Then, the right side strip 201 is slid to the left. The rotating plate 202 rotates around the rotating shaft 203 as the axis, simultaneously driving the right side strip 201 to the left under the guidance of the pulley 204 and the sliding groove 205. As the right-side strip 201 moves, the rotating plate 202 continuously rotates and contracts, gradually expanding the passage space until it is fully open, meeting the needs of large maintenance equipment entry and exit and personnel operations. When closing the passage after maintenance is completed, the operation is reversed: first, the right-side strip 201 slides to the right along the slide groove 205, causing the rotating plate 202 to rotate and unfold until all rotating plates 202 return to their initial closed state. Then, the locking plate 206 is rotated to engage with the locking groove 207, re-fixing the right-side strip 201. Finally, the rotating door 208 is closed via the door handle 210. The hinge 209 positions the rotating door 208 tightly, and the passage mechanism 2 once again forms a complete protective system, ensuring the safe operation of the pump station equipment.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
