Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a damaged rubber dam bag repairer. Background Art

[0002] A rubber dam, also known as a rubber sluice, is a new type of water retaining and discharge system. It uses a high-strength fiber fabric as a load-bearing framework, coated internally and externally with rubber as a protective layer. This is processed into a tape, which is then anchored to the base plate to form a closed dam bag. This bag is filled with water or air via a pump, air compressor, and charging and discharging pipes, causing it to expand to retain water and collapse to drain water. The dam's crest can overflow, and its height can be adjusted as needed. This allows for convenient and rapid control of river water levels and flows, providing a wide range of benefits in water supply, irrigation, power generation, shipping, flood control, and tide control.

[0003] Rubber dams are a combination of rigid and flexible engineering structures. The gate piers, bank walls, bottom plates, and energy dissipation and anti-scouring facilities are constructed of concrete or reinforced concrete, which are rigid materials. The dam bags used for retaining and discharging water are made of adhesive tape, which are flexible, thin-walled, and hollow structures. During operation, punctures, scratches, wear, debonding, blistering, and tape tearing are inevitable. If the dam bag damage is not repaired promptly and effectively, it may cause further tearing, resulting in the entire dam bag being scrapped, the stored water being lost, or even a sudden rupture and collapse of the dam, with the stored water rapidly discharging and causing casualties and damage to equipment and facilities. Therefore, in order to prevent the dam bag damage from further expanding and endangering the dam bag, engineering equipment, and even personal safety, the dam bag damage must be repaired using appropriate methods once it is discovered. Dam bag repair is a regular and very important task in the operation and management of rubber dam projects.

[0004] In the prior art, the methods for repairing dam bags mainly include suturing, patching, splinting and combining.

[0005] The suturing method generally uses fiber thread with the same elongation as the fiber of the dam bag tape to drill holes and thread around the cracks in the dam bag to sew. Wrinkles are easily generated after sewing, which changes the stress state of the dam bag and easily causes stress concentration. It is suitable for repairing damaged dam bags with longer cracks and smaller designed tape tension.

[0006] Patching involves applying glue to damaged areas. This method requires demanding adhesive bonding conditions and cannot be applied in the presence of water. The bonding surface must be sanded, dry, and dust-free. Patching is not possible in cold temperatures, rainy days, strong sandstorms, water, or underwater conditions. Patching requires pressure with a heavy object and typically requires at least 24 hours before use. Glue is toxic, potentially posing a risk to personnel and potentially polluting water.

[0007] The splinting method uses steel plates and bolts to patch torn dam bags. While relatively quick and easy, it's generally suitable for larger tears or gaps. For smaller leaks, the plywood can be difficult to insert through the hole and into the dam bag's tape, making the repair more challenging. A weak anchor can also lead to leaks. In some cases, cutting the hole to insert the plywood can enlarge the damage, further damaging the dam bag.

[0008] The combination method is to select one or more of the above three methods and combine them with each other. The repair process is cumbersome and the scope of application is narrow.

[0009] Based on the above reasons, the existing methods for repairing damaged rubber dam bags have various drawbacks and are difficult to meet the needs of rubber dam bag operation and maintenance. It is urgent to develop a rubber dam bag repair tool with simple structure, low cost, easy operation, convenience and speed, and wide applicability. Utility Model Content

[0010] In order to solve the above problems, the present invention provides a rubber dam bag damage repairer. The technical solution of the present invention is as follows:

[0011] The rubber dam bag damage repairer consists of three parts: an umbrella nail, an anchor plate, and a nut. The umbrella nail consists of a central screw, a cantilever rod, a rubber membrane, and a side screw. The nuts are divided into central nuts and side nuts. The device is characterized by a central screw connected to multiple cantilever rods via a bearing with a limiter and a torsion spring, and the cantilever rods are connected to the side screws via bearings with a limiter and a torsion spring. A soft rubber membrane is provided between the cantilever rods. The central screw is fastened to the central nut via a thread, and the side screws are fastened to the side nuts via a thread.

[0012] The described rubber dam bag damage repairer is characterized in that when the dam bag is damaged, the umbrella nail is inserted into the hole and the pin is turned, the umbrella nail is unfolded like an umbrella, and the rubber membrane on the umbrella nail is tightly fitted with the inner side of the tape at the damaged part of the dam bag under the action of the water pressure of the gushing water, and the gushing water at the damaged part is blocked. The middle nut and the side nut are inserted into the middle screw and the side screw and tightened, and the excess screw is cut off and polished to complete the dam bag damage repair.

[0013] The umbrella rivet is an umbrella-shaped, rigid-flexible screw, consisting of a central screw, cantilever rods, a rubber membrane, and side screws. The central screw is located in the center, and is surrounded by multiple cantilever rods and side screws. A soft rubber membrane is placed between each cantilever rod. The central screw is equipped with a sliding latch. When the latch is locked, the umbrella rivet is in a closed position, with the cantilever rods and the central screw forming a 0-degree angle, and the side screws and cantilever rods forming a straight line. When the latch is released, the umbrella rivet is in an open position, with the cantilever rods and side screws automatically springing open, and the rubber membranes between the cantilever rods are expanded. The bearings limit the angles between the cantilever rods and the central screw, and between the side screws and the cantilever rods, to 90 degrees, due to the action of torsion springs. The central screw's latch has a groove between it for positioning.

[0014] The anchor plate is a circular steel plate coated with an organic plastic coating on the outside, which is used for sealing, water-stopping and corrosion protection of the anchor plate. In order to accurately determine the hole position of the dam bag tape through the hole position of the anchor plate, a protrusion corresponding to the groove of the middle screw is set in the hole of the anchor plate.

[0015] The nut is divided into a middle nut and a side nut, which are respectively fastened to the middle screw rod and the side screw rod through threads.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The rubber dam bag damage repairer adopts a rigid-flexible movable structure, which avoids the disadvantage of the traditional splint method that the damage is enlarged in order to insert the splint into the hole, thereby causing further damage to the dam bag. Large holes, small holes, round holes and long seams can be repaired.

[0018] (2) The repair conditions are low and can be completed under low temperature, rainy days, strong wind and sand conditions. There is no need to grind the bonding surface to make it rough, dry and dust-free. After the patch is completed, there is no need to use heavy objects to press it flat. The repair can be carried out under conditions where there is water in the dam bag or water is gushing, and it can even be completed underwater.

[0019] (3) The rubber dam bag damage repairer has high repair reliability and adopts triple protection of rubber film bonding, bolt fastening and organic plastic coating anchor plate. After repair, it is leak-proof and durable.

[0020] (4) The repair operation is simple and has low technical requirements for the repair personnel. The repair can be completed in a very short time and can be put into use immediately after the repair. There is no need to wait and it can be used for emergency repairs as well as daily repairs.

[0021] (5) The rubber dam bag damage repairer does not require glue, is non-toxic, and will not pollute water quality or poison management personnel.

[0022] (6) It can be processed into full-size standard parts in the factory and implemented in factory batch production, or it can be customized according to special needs. It has a wide range of applications and extremely low production and installation costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] This utility model provides a repair device for damaged rubber dam bags. It is suitable for repairing damaged rubber dam bags. The following, combined with the accompanying drawings, provides a clear and complete description of the technical solutions in the embodiments of this utility model. Obviously, the described embodiments represent only a portion of the embodiments of this utility model, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0043] The umbrella tack 1 is an umbrella-shaped, rigid-flexible screw, consisting of a central screw 2, cantilever rods 3, a rubber membrane 4, and side screws 5. The central screw 2 is located in the center, surrounded by multiple cantilever rods 3 and side screws 5. A flexible rubber membrane 4 is placed between each cantilever rod 3. A sliding latch 6 is attached to the central screw 2. When the latch 6 is locked, the umbrella tack 1 is in the closed position, with the cantilever rods 3 and central screw 2 forming a zero-degree angle, and the side screws 5 and cantilever rods 3 aligned. When the latch 6 is released, the umbrella tack 1 is in the open position, with the cantilever rods 3 and side screws 5 automatically springing open, and the rubber membranes 4 between the cantilever rods 3 are expanded. Bearings 7 limit the angles between the cantilever rods 3 and central screw 2, and between the side screws 5 and cantilever rods 3, and the torsion springs act to create a 90-degree angle. The central screw 2 has a positioning groove 8 between the latch 6.

[0044] The anchor plate 9 is a circular steel plate 10 coated with an organic plastic coating 11 for sealing, waterproofing and corrosion protection. In order to accurately determine the drilling position of the dam bag tape 23 through the hole position of the anchor plate 9, a protrusion 12 is set in the hole of the anchor plate 9 corresponding to the groove 8 of the middle screw 2.

[0045] The nuts are divided into a middle nut 13 and a side nut 14, which are respectively fastened to the middle screw 2 and the side screw 5 through threads. Figure 1-3 shown.

[0046] like Figure 4-12 As shown, the specific repair procedure of the rubber dam bag damage repairer is as follows.

[0047] (1) When the dam bag is damaged, insert the umbrella nail 1 into the hole 15.

[0048] (2) Push the latch 6, and the cantilever rod 3 rotates to a position perpendicular to the middle screw 2 under the action of the torsion spring. The side screw 5 rotates to a position perpendicular to the cantilever rod 3 under the action of the torsion spring. The rubber membrane 4 is unfolded and, under the action of the water pressure from the damaged part, fits tightly against the inner side of the tape at the damaged part of the dam bag, and the water from the damaged part is blocked.

[0049] (3) Insert the anchor plate 9 into the middle screw 2.

[0050] (4) Drill holes in the dam bag tape through the holes in the anchor plate 9 and pass the side screw 5 through the holes from the inside to the outside.

[0051] (5) Insert the middle nut 13 into the middle screw 2 and tighten it, and insert the side nut 14 into the side screw 5 and tighten it.

[0052] (6) Cut off the excess parts of the side screw 5 and the middle screw 2 outside the middle nut 13 and the side nut 14 and grind them smooth. This step can also be pre-done as needed, and the cutting and grinding can be done after the lengths of the side screw 5 and the middle screw 2 are accurately measured.

[0053] The present invention will be further described below with reference to Examples 1-3.

[0054] Example 1: This example provides a simplified version of a rubber dam bag damage repairer. The difference of the simplified version of the rubber dam bag damage repairer is that the skeleton structure of the umbrella nail 1 has no edge screws, and is composed only of a middle screw 2 and a cantilever rod 3. The middle screw has no groove for positioning, the anchor plate has only a middle hole and no protrusions, and the dam bag tape does not need to be drilled. It is suitable for emergency repairs and repairs of non-important rubber dam bag damage. Figure 13-16 shown.

[0055] Example 2: The cantilever rod 3 in the umbrella nail 1 of the rubber dam bag damage repairer can be set to three spokes 16, four spokes 17, five spokes 18, six spokes 19, seven spokes 20, eight spokes 21, etc. according to the needs of engineering repair. The larger the number of spokes, the greater the rigidity and the better the sealing performance. Figure 17 shown.

[0056] Example 3: When the rubber dam bag damage repairer is used to repair a long crack 22, it can be arranged linearly 24 according to the direction of the crack 22. Figure 18 shown.

[0057] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
