Description

Technical Field

[0001] The utility model relates to the technical field of hole blocking equipment, in particular to a hole blocking equipment in a gate chamber of a water diversion project. Background Art

[0002] In the lock chamber of a water diversion project or natural river, gates and their supporting equipment and sewage cleaning equipment are generally installed. Sewage cleaning equipment needs to wade through water, so there are generally gate holes in the lock chamber that are connected to the outdoor river or channel. During normal water transfer operation, moisture from the water flow below, flying insects, etc. enter the lock chamber from the hole, causing the equipment to become damp and the sanitary conditions to deteriorate.

[0003] After searching, the patent (application number: 202121973001.6) discloses "a device for plugging the orifice in the lock chamber of a water diversion project". This new device can be promoted and used as a hole plugging facility for the same type of water flow channels. It can not only ensure the normal operation of equipment such as gates and sewage cleaning machines entering the hole, but also isolate the channel water flow from the lock chamber, effectively prevent moisture in the culvert from evaporating into the lock chamber, solve the problem of dampness in the lock chamber, and improve the sanitary condition of the lock chamber. However, the device has the following shortcomings in actual use:

[0004] The device mainly blocks the inner opening of the gate chamber by laying a blocking rolling shutter member. Each time the inner opening of the gate chamber is opened, the blocking rolling shutter member from bottom to top needs to be rolled up, all parts need to be coordinated, the opening method is single, and the maintenance cost is high. In addition, the door frames on both sides of the door panel filled with high-pressure polyurethane are not connected and need to be installed separately. The installation position needs to be constantly adjusted during installation, which makes the installation difficult. Utility Model Content

[0027] In this embodiment, the servo motor 2 is used to drive the bidirectional screw rod 3 to rotate, and the first sealing plate 5 and the second sealing plate 6 respectively connected to the two slides 4 can approach or move away from each other, which not only realizes the rapid sealing of the orifice in the gate chamber, but also can directly open up the passage space from the orifice position in the gate chamber, making it convenient for operators to carry equipment through.

[0028] Example 2, refer to Figure 2 , a device for sealing the orifice in a gate chamber of a water diversion project, wherein the inner wall of the first sealing plate 5 is rotatably connected to a rotating shaft 7, and a sealing circular plate 8 is welded to the outer wall at the bottom of the rotating shaft 7, a connecting piece 9 is welded to the outer wall of the rotating shaft 7, and a cylinder 10 is hinged between the connecting piece 9 and the first sealing plate 5.

[0029] In this embodiment, the sealing circular plate 8 connected to the rotating shaft 7 can be controlled to rotate by adjusting the piston rod length of the cylinder 10, thereby adjusting the size of the wall-penetrating groove 16, which can provide passage conditions for small-sized equipment in a smaller space. It not only has the characteristics of diversified opening, but also does not require the linkage of all parts, thereby reducing maintenance costs.

[0030] Example 3, refer to Figure 3 A device for sealing the orifice in a gate chamber of a water diversion project, wherein the outer walls of the top and bottom of the frame 1 are welded with symmetrically distributed hanging ears 11, and the inner walls of the grooves of the hanging ears 11 are provided with positioning columns 12, and the outer walls of the positioning columns 12 are located on both sides of the hanging ears 11 and are welded with positioning rings 13.

[0031] In this embodiment, the frame 1 is the main structure, and other parts can be distributed by unfolding the frame 1. Since multiple hanging ears 11 are fixed on the frame 1, the installation method of fixing the frame 1 to the wall 22 by bolts is replaced. The hanging ears 11 can be directly placed on the positioning columns 12 and positioned by the positioning rings 13, so that the assembly of the entire device can be completed quickly and disassembly is convenient.

[0032] Reference Figure 2 A first rubber sheet 14 is bonded to one side of the outer wall of one side of the sealing circular plate 8 , and a second rubber sheet 15 is bonded to one side of the outer wall of the other side of the sealing circular plate 8 .

[0033] Reference Figures 1 to 2 A through-wall groove 16 is defined between the first blocking plate 5 and the second blocking plate 6 , and the sealing circular plate 8 is disposed inside the through-wall groove 16 .

[0034] Reference Figures 1 to 3 Limit rods 17 are welded on both sides of the inner wall of the frame 1, and the first blocking plate 5 and the second blocking plate 6 are slidably connected to the outer wall of the limit rod 17.

[0035] Reference Figure 1 The outer walls of one side of the first blocking plate 5 and the second blocking plate 6 are fixedly connected to a connecting column 18, and the outer wall of one end of the connecting column 18 is rotatably connected to a pulley 19.

[0036] Reference Figure 1 A positioning groove 20 is provided at the bottom of the outer wall of one side of the frame 1, and the pulley 19 is slidably connected to the inner wall of the positioning groove 20.

[0037] Reference Figures 1 to 3 The top outer wall of the frame 1 is welded with symmetrically distributed hanging rings 21.

[0038] Reference Figures 1 to 3 The outer wall of one end of the positioning column 12 is screwed with the wall 22, and the frame 1 is close to the outer wall of one side of the wall 22.

[0039] Working principle: The device is based on the frame 1 as the main structure, and other parts are distributed by unfolding the frame 1. By placing the ear 11 on the positioning column 12 and relying on the positioning ring 13 for positioning, the assembly of the entire equipment can be quickly completed. Under normal conditions, the opening in the gate chamber is blocked by closing the first sealing plate 5 and the second sealing plate 6. If necessary, the sealing circular plate 8 connected to the rotating shaft 7 can be controlled to rotate by adjusting the piston rod length of the cylinder 10, thereby adjusting the size of the wall-penetrating groove 16 to provide passage conditions for small-sized equipment in a smaller space. Alternatively, the servo motor 2 is used to drive the bidirectional screw 3 to rotate, so that the first sealing plate 5 and the second sealing plate 6 are separated from each other, thereby expanding the passage space and facilitating the operator to carry the equipment through.
