Description

Technical Field

[0001] This utility model relates to the technical field of industrial water tank repair tools, and in particular to a tool for replacing parts in industrial water tanks. Background Technology

[0002] Wave flumes are core experimental facilities for marine engineering experiments. They are generally about 32m long × 0.80m wide × 1m high. They integrate a pusher-type wave generation system and bidirectional current generation technology, which can accurately simulate complex ocean wave-current coupling environment and provide convenient conditions for the study of ocean currents. However, existing wave flumes generally face the problem of difficulty in replacing parts when the flume parts are damaged during the experiment.

[0003] For example, Chinese utility model patent CN205588221U discloses a tool for replacing parts in an industrial water tank. Although the tool proposed by this solution eliminates the need to drain the liquid from the tank during maintenance and facilitates the replacement of faulty parts by creating a partially emptied replacement space, it is very difficult to drain the water that enters between the first and second gates after the water flow is blocked by the first and second gates. Furthermore, relying solely on sealing strips on the edges of the gates to prevent external water from seeping into the space between the first and second gates may result in unreliable anti-seepage performance.

[0004] In view of this, a tool for replacing parts in an industrial water tank is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problem of sealing and waterproofing performance of tools for replacing parts in industrial water tanks, this utility model provides a tool for replacing parts in industrial water tanks.

[0006] This utility model is achieved using the following technical solution: a tool for replacing parts in an industrial water tank, comprising an outer cylinder, a vacuum suction cup base fixedly connected to the lower side of the outer cylinder, a sealing gasket installed on the lower side of the vacuum suction cup base, an inner sealing cylinder rotatably connected to the inner side of the vacuum suction cup base, an inner cylinder fixedly connected to the upper side of the inner sealing cylinder and rotatably connected to the inner side of the outer cylinder, a plurality of outer water tank holes being opened on the side of the vacuum suction cup base near the inner sealing cylinder, the plurality of outer water tank holes being distributed in a circumferential array, a plurality of inner water tank holes being opened on the inner sealing cylinder, the plurality of inner water tank holes being paired with the plurality of outer water tank holes, a drainage mechanism and a sealing adsorption mechanism being respectively provided on the upper side of the inner cylinder, and an inner cylinder drive mechanism for rotating the inner cylinder being provided on the upper side of the inner cylinder.

[0007] As a further improvement to the above solution, the drainage mechanism includes a ring fixedly connected to the upper side of the inner cylinder, a drain pipe communicating between the ring and the lower side of the inner cylinder, and a water pump installed on the upper side of the ring, the water pump communicating with the drain pipe.

[0008] As a further improvement to the above solution, the sealing adsorption mechanism includes an exhaust pipe that connects the ring and the lower side of the inner cylinder, and a vacuum pump is installed on the upper side of the ring, with the output end of the vacuum pump connected to the exhaust pipe.

[0009] As a further improvement to the above solution, the inner cylinder driving mechanism includes a gear ring fixedly connected to the upper side of the outer cylinder, a fixing plate fixedly connected to the upper side of the ring, a servo motor mounted on one side of the fixing plate, a gear fixedly connected to the output end of the servo motor, the gear meshing with the gear ring, and a switching mechanism provided on the upper side of the vacuum suction cup base.

[0010] As a further improvement to the above solution, the switching mechanism includes a through groove that is opened through the top of the inner side of the vacuum suction cup base, and the through groove is configured to cooperate with the lower port of the exhaust pipe and the lower port of the drain pipe.

[0011] As a further improvement to the above solution, a control panel is installed on one side of the fixing plate, and the control panel is electrically connected to the vacuum pump and the water pump.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model inserts the outer cylinder into the water tank around the part to be replaced, then first uses a water pump to drain the water in the inner cylinder, and then uses a vacuum pump to remove the air from the vacuum suction cup base, so that the sealing gasket firmly adheres to the inner wall of the water tank, which can stably form a water-proof space around the part, and has the advantages of strong waterproof performance and high reliability. 2. This utility model involves inserting the outer cylinder into the water tank around the part to be replaced. The control panel automatically starts the water pump, servo motor, and vacuum pump in sequence. First, the water pump drains the water from the vacuum suction cup base and the inner cylinder. Then, the servo motor drives the gear to rotate, switching the exhaust pipe to align with the connecting groove. Finally, the vacuum pump is started to expel the air from the vacuum suction cup base, creating negative pressure to tightly adhere the sealing gasket. Then, the operator can reach the part to be replaced at the bottom of the water tank through the inner cylinder without having to completely drain the water tank. It has the advantages of simple operation and convenient use. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] Example: Please combine Figures 1-3 This embodiment describes a tool for replacing parts in an industrial water tank, including an outer cylinder 1. A vacuum suction cup base 2 is fixedly connected to the lower side of the outer cylinder 1. Please refer to... Figure 4 As shown, the vacuum suction cup base 2 has an annular groove structure inside, a rounded corner grinding structure on the outside, and an inner cylindrical outer wall, which facilitates dynamic sealing docking. Please combine Figure 3 As shown, a sealing gasket 3 is installed on the lower side of the vacuum suction cup base 2. Vacuum suction cups are generally made of rubber because rubber suction cups have good elasticity and sealing properties, and can closely adhere to the surface of the adsorbed object to form a vacuum space to generate adsorption force. Common materials include nitrile rubber (NBR), polyurethane rubber (PU), fluororubber (FKM), and silicone rubber (SI). Different materials are suitable for different scenarios. Please combine Figure 2 As shown, an inner sealing cylinder 17 is rotatably connected to the inner side of the vacuum suction cup base 2, and an inner cylinder 4, which is rotatably connected to the inner side of the outer cylinder 1, is fixedly connected to the upper side of the inner sealing cylinder 17. Please refer to... Figure 5As shown, in this embodiment, the vacuum suction cup base 2 has four external water groove holes 19 on the side near the inner sealing cylinder 17. The four external water groove holes 19 are arranged in a circumferential array. The inner sealing cylinder 17 has four internal water groove holes 15. The four internal water groove holes 15 are paired with the four external water groove holes 19. When the inner sealing cylinder 17 rotates, the external water groove holes 19 and the internal water groove holes 15 can be aligned or staggered. When aligned, water can flow inside and outside. When staggered, a sealing environment can be provided for the vacuum pump. Please combine Figure 4 As shown, a drainage mechanism and a sealing and adsorption mechanism are respectively provided on the upper side of the inner cylinder 4, and an inner cylinder drive mechanism for rotating the inner cylinder 4 is provided on the upper side of the inner cylinder 4.

[0017] Please combine Figure 4 As shown, the drainage mechanism includes a ring 13 fixedly connected to the upper side of the inner cylinder 4, a drain pipe 6 connecting the ring 13 and the lower side of the inner cylinder 4, a water pump 11 installed on the upper side of the ring 13, and the water pump 11 connected to the drain pipe 6. The drainage mechanism can drain the water inside the inner cylinder 4, thereby exposing the bottom water tank parts that need to be replaced. Please combine Figure 4 As shown, the sealed adsorption mechanism includes an exhaust pipe 5 that connects the ring 13 and the lower side of the inner cylinder 4. A vacuum pump 12 is installed on the upper side of the ring 13. The output end of the vacuum pump 12 is connected to the exhaust pipe 5. When the vacuum pump 12 is started, it can create a negative pressure environment, thereby generating an adsorption effect. Please combine Figure 2 As shown, the inner cylinder drive mechanism includes a gear ring 14 fixedly connected to the upper side of the outer cylinder 1, a fixing plate 9 fixedly connected to the upper side of the ring 13, a servo motor 8 installed on one side of the fixing plate 9, a gear 7 fixedly connected to the output end of the servo motor 8, the gear 7 meshing with the gear ring 14, and a switching mechanism provided on the upper side of the vacuum suction cup base 2.

[0018] Please combine Figure 2 As shown, the switching mechanism includes a connecting groove 18 that is opened through the top of the inner side of the vacuum suction cup base 2. The connecting groove 18 is configured to cooperate with the lower port of the exhaust pipe 5 and the lower port of the drain pipe 6. By switching the connecting groove 18 with the lower port of the exhaust pipe 5 and the drain pipe 6, the alignment and connection status can be changed, thereby achieving the effect of drainage or vacuum exhaust. Please combine Figure 1 As shown, a control panel 10 is installed on one side of the fixing plate 9, and the control panel 10 is electrically connected to the vacuum pump 12 and the water pump 11.

[0019] The implementation principle of a tool for replacing parts in an industrial water tank according to this application embodiment is as follows: The entire device is placed in the water tank where the part to be replaced needs to be placed, with the outer cylinder 1 positioned around the part. Manual assistance is used to press downwards, temporarily bringing the sealing gasket 3 into contact with the bottom of the water tank. Then, the water pump 11 is started via the control panel 10, and the water inside the vacuum suction cup base 2 and the inner cylinder 4 is fully discharged through the drain pipe 6. When the inner cylinder 4 is initially positioned, the multiple inner water groove holes 15 inside the inner sealing cylinder 17 below the inner cylinder 4 are aligned one-to-one with the outer water groove holes 19 on the vacuum suction cup base 2, allowing water to flow along the inner water groove. Hole 15 and outer water tank hole 19 enter the vacuum suction cup base 2 and are discharged through drain pipe 6. Then, servo motor 8 is started to drive gear 7 to rotate, pushing inner cylinder 4 to rotate. This causes drain pipe 6, which was initially connected to connecting groove 18, to switch to being connected to the top of connecting groove 18 via exhaust pipe 5. After rotation, inner water tank hole 15 on inner sealing cylinder 17 and outer water tank hole 19 on vacuum suction cup base 2 are offset from each other. At this time, vacuum pump 12 is started to discharge air from sealing gasket 13 and vacuum suction cup base 2, thereby generating negative pressure and achieving the effect of firmly fixing sealing gasket 13 and vacuum suction cup base 2 to the inner wall of water tank.

[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
