Description

Technical Field

[0001] This utility model relates to the field of maintenance gate technology, and in particular to a bottom support bracket for maintenance gate. Background Technology

[0002] Inspection gates are temporary water-blocking gates used for the maintenance of hydraulic structures or working gates and their slots. According to the pump station pump maintenance regulations, equipment conditions are checked regularly every six months before and after the flood season to identify defects and abnormalities and perform routine maintenance. Regular inspections of the pump impeller and impeller chamber require emptying the water accumulated in the inlet channel connected to the forebay to create basic environmental conditions for maintenance. Therefore, it is necessary to open or close the inspection gate on the corresponding side to empty the accumulated water.

[0003] The sealing performance of a gate depends primarily on the sealing rubber. However, in actual use, especially the sealing rubber at the bottom of the gate, which is also a major supporting component, it is deformed due to prolonged pressure from the gate's own weight, resulting in permanent damage and significantly reducing the gate's sealing effect. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a bottom support bracket for maintenance gates. It features a reasonable structural design and convenient installation. The bracket can replace the water-stop rubber to share the gate's weight, preventing severe deformation of the water-stop rubber due to prolonged pressure from the gate. This keeps the deformation of the water-stop rubber within a controllable range, achieving the desired sealing effect without causing damage, effectively ensuring the gate's water-stopping performance and solving the problems existing in the prior art.

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

[0006] A maintenance gate bottom support bracket includes a base plate and vertical plates symmetrically and vertically arranged on the front and rear sides of the base plate. Baffles connected to the two vertical plates on the corresponding sides are symmetrically arranged at the left and right ends of the base plate. A mounting groove is provided along the length of the base plate in the middle of its surface, and a plurality of mounting holes are spaced apart along the length of the mounting groove. A lower pressure plate is provided on the surface of the base plate, with its left and right ends abutting against the baffles on the corresponding sides. A positioning strip is provided at the bottom of the lower pressure plate corresponding to the mounting groove position to engage with it. The lower pressure plate is further supported on the front and rear sides of its surface. Two glue-injection baffles are symmetrically arranged along their length. Mounting plates that are fixed to the base plate are provided at the left and right ends of the outer walls of the two glue-injection baffles. Two L-shaped limiting plates are symmetrically arranged along their length on the side walls of the two vertical plates on opposite sides. Guide grooves are opened along their length in the middle of the horizontal sections of the two L-shaped limiting plates. Several support members are spaced apart along their length on the base plate corresponding to the positions of the two L-shaped limiting plates. Adjustment grooves that cooperate with the support members are opened in the middle of the two vertical plates below the L-shaped limiting plates along their length.

[0007] Optionally, the support includes an adjusting sleeve, the upper end of which abuts against the bottom of the L-shaped limiting plate, and the lower end of which abuts against the base plate. Both the upper and lower ends of the adjusting sleeve are provided with annular locking blocks. An adjusting seat is provided on the side wall of the adjusting sleeve at the position corresponding to the adjusting groove. Limiting seats are provided at the upper and lower ends of the adjusting seat, respectively, and are movably fitted onto the adjusting sleeve. An annular groove is provided on the limiting seat at the position corresponding to the annular locking block, cooperating with the annular locking block. A lead screw is threaded into the adjusting sleeve, and its upper end extends through a guide groove and is movably connected to the support seat.

[0008] Optionally, retaining rings that fit onto the adjusting sleeve are provided at the upper and lower ends of the adjusting seat, and retaining grooves that cooperate with the retaining rings are provided on the limiting seat at the corresponding retaining ring positions.

[0009] Optionally, a groove is provided on the lead screw sidewall on the upper side along its circumference, and an annular slider is provided in the locking hole at the bottom of the support base to engage with the groove.

[0010] Optionally, a rubber pad is provided on the bottom of the base plate.

[0011] The advantages of this utility model using the above-mentioned technical solution are: reasonable structural design and convenient installation. The bracket can replace the water-stop rubber to share the weight of the gate, avoiding severe deformation of the water-stop rubber due to long-term pressure from the gate. This keeps the deformation of the water-stop rubber within a controllable range, achieving the proper sealing effect without causing damage, and effectively ensuring the water-stopping effect of the gate.

[0023] like Figure 1-7As shown in this embodiment, a maintenance gate bottom support bracket includes a base plate 1 and vertical plates 2 symmetrically and vertically arranged on the front and rear sides of the base plate 1. Baffles 3 are symmetrically arranged at the left and right ends of the base plate 1, connecting to the two vertical plates 2 on the corresponding sides. An installation groove 4 is provided along the length of the base plate 1 in the middle of its surface. A plurality of installation holes 5 are spaced apart along the length of the installation groove 4. A lower pressure plate 6 is provided on the surface of the base plate 1. The left and right ends of the lower pressure plate 6 abut against the baffles 3 on the corresponding sides. A positioning strip 7 is provided at the bottom of the lower pressure plate 6 corresponding to the installation groove 4, engaging with it. The lower pressure plate 6 surface... A glue injection baffle 8 is symmetrically provided on the front and rear sides along its length. Mounting plates 9, which are fixed to the base plate 1, are provided on the left and right ends of the outer walls of the two glue injection baffles 8. L-shaped limiting plates 10 are symmetrically provided on the side walls of the two vertical plates 2 on the opposite side along their length. Guide grooves 11 are opened in the middle of the horizontal sections of the two L-shaped limiting plates 10 along their length. Several support members are provided at intervals along their length on the base plate 1 at the positions corresponding to the two L-shaped limiting plates 10. Adjustment grooves 12 that cooperate with the support members are opened in the middle of the two vertical plates 2 below the L-shaped limiting plates 10 along their length.

[0024] Optionally, the support includes an adjusting sleeve 13, the upper end of which abuts against the bottom of the L-shaped limiting plate 10, and the lower end of which abuts against the base plate 1. Both the upper and lower ends of the adjusting sleeve 13 are provided with annular locking blocks 14. An adjusting seat 15 is provided on the side wall of the adjusting sleeve 13 at the position corresponding to the adjusting groove 12. Limiting seats 16, which are movably fitted onto the adjusting sleeve 13, are provided at the upper and lower ends of the adjusting seat 15. An annular groove 17, which cooperates with the annular locking block 14, is provided on the limiting seat 16 at the position corresponding to the annular locking block 14. A lead screw 18 is threaded into the adjusting sleeve 13, and its upper end extends through the guide groove 11 and is movably connected to the support seat 19.

[0025] Optionally, retaining rings 20 are provided at the upper and lower ends of the adjusting seat 15, respectively, and retaining grooves 21 are provided on the limiting seats 16 at the corresponding positions of the retaining rings 20. Through the cooperation of the retaining rings 20 and the retaining grooves 21, the adjusting seat 15 can be more stably engaged in the limiting seats 16 on the upper and lower sides.

[0026] Optionally, a groove 22 is provided along the circumference of the side wall of the lead screw 18 on the upper side, and an annular slider 24 is provided in the locking hole 23 at the bottom of the support base 19 to engage with the groove 22. The support base 19 can be connected to the lead screw 18 through the annular slider 24 to prevent the support base 19 from slipping outward.

[0027] Optionally, a rubber pad 25 is provided at the bottom of the base plate 1. The rubber pad 25 can further improve the sealing performance between the base plate 1 and the bottom of the pool.

[0028] During installation, the base plate 1 is first placed at the bottom of the pool and secured firmly with multiple expansion bolts passing through the mounting holes 5 of the mounting groove 4. Next, the lower pressure plate 6 is tilted and inserted between the two L-shaped limiting plates 10, with its bottom positioning strip 7 engaging within the mounting groove 4 of the base plate 1. This serves both to position the lower pressure plate 6 between it and the base plate 1 and to facilitate the secure fixing of the lower pressure plate 6 to the base plate 1 via the mounting plates 9. Then, depending on the gate size, different vertical beam supports are selected for coordination, with each support abutting against the bottom of the grid-like side ribs on the gate's sidewall for support. Specifically, the limiting seat 16 is inserted from the outside of the L-shaped limiting plate 10. Because the mounting plates 9 and the L-shaped limiting plates 10 are staggered, a space is created for the limiting seat 16 to insert. Therefore, the adjusting sleeve 13 and the limiting seats 16 on both sides are smoothly inserted. The upper limiting seat 16 is movably engaged in the L-shaped limiting plate 10, which serves as a limiting function, while the lower limiting seat 16 abuts against the base plate 1. After horizontally pushing it to the corresponding position, the lower end of the lead screw 18 is passed through the guide groove 11 and threaded into the adjusting sleeve 13. From one side of the adjusting groove 12, the adjusting seat 15 is rotated to adjust the height of the lead screw 18, so that the top support seat 19 is aligned with the bottom of the grid-like side ribs of the gate. Finally, glue is injected into the template formed by the two glue injection baffles 8, the lower pressure plate 6, and the two vertical plates 2 on both sides, and left to solidify. Then, the gate is lowered, so that the water-stop rubber at the bottom of the gate abuts against the glue in the template, and the glue effectively cushions the water-stop rubber. Then, adjust each adjusting seat 15 one by one, causing the lead screw 18 to move upwards continuously until the support seat 19 abuts against the bottom of the grid-like side ribs, thereby forming effective support for the gate and preventing the gate's own weight from being concentrated entirely on the water-stop rubber. Its structural design is reasonable and easy to install. The bracket can replace the water-stop rubber to share the gate's weight, preventing the water-stop rubber from being severely deformed due to prolonged pressure from the gate. This keeps the deformation of the water-stop rubber within a controllable range, achieving the necessary sealing effect without causing damage, effectively ensuring the gate's water-stopping effect and solving the problems existing in the prior art.
