[0002] Leakage is a common disease of dams and is also a precursor danger of dam break during the flood season. Quickly plugging underwater leakage passages has important engineering significance for the emergency rescue of dams. Currently, there are various methods for dealing with leakage diseases, but there are still various deficiencies in quickly plugging leaks during the flood season, especially the inapplicability of emergency plugging of underwater leakage passages of dams, resulting in untimely plugging, and the operation of the underwater plugging sealing device is relatively difficult and not easy to perform sealing operations. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a sealing device for a leakage passage that is convenient for emergency plugging of underwater leakage passages of dams, is easy to operate, and is easier to plug.

A sealing block made of a flexible sealing material is provided at the place to be sealed between the plugging head and the passage to be sealed. Bolt holes are provided on the plugging head, and fastening bolts are inserted into the bolt holes. A stamping bracket is erected on the passage to be sealed, and a stamping mechanism is provided on the stamping bracket. The stamping end of the stamping mechanism corresponds to the end of the plugging head away from the passage to be sealed.

[0005] The stamping mechanism includes a housing. A stamping port corresponding to the plugging head is provided at the front end of the housing. A stamping piston is provided inside the housing. One end of the stamping piston extends out of the stamping port. The upper part of the housing inside the stamping piston is a stamping chamber, and the stamping chamber is communicated with a hydraulic pump through a sealing pipe above.

[0006] The flexible sealing material is rubber.

[0007] The stamping piston has a convex-shaped structure.

[0008] The bottom end of the plugging head has an arc transition.

[0009] The number of the fastening bolts is two, and they are respectively arranged at the left and right ends of the plugging head.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] When the present invention seals the leakage channel, a corresponding sealing channel to be sealed is excavated at the place to be sealed. During stamping, the stamping mechanism is used to stamp the plugging head, and the sealing block is stamped into the sealing channel to be sealed. Then, the plugging head is fixed by the fastening bolt. The present invention has the advantages of convenient leakage plugging, high leakage plugging efficiency and easy operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 is a schematic structural diagram of the present invention when the plugging head is not plugged. DETAILED DESCRIPTION OF THE INVENTION

[0014] The following further describes the specific embodiments of the present invention with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0015] Please refer to Figure 1-2 , a sealing device for a leakage channel of the present invention includes a plugging head 2 for being embedded in the sealing channel 1 to be sealed. A sealing block 3 made of a flexible sealing material is arranged between the plugging head 2 and the place to be sealed of the sealing channel 1 to be sealed. A bolt hole is opened on the plugging head 2, and a fastening bolt 4 is inserted through the bolt hole. A stamping support 5 is erected on the sealing channel 1 to be sealed, and a stamping mechanism 6 is arranged on the stamping support 5. The stamping end of the stamping mechanism 6 corresponds to the end of the plugging head 2 away from the sealing channel 1 to be sealed. When sealing the leakage channel, a corresponding sealing channel 1 to be sealed is excavated at the place to be sealed. The depth of the excavated sealing channel 1 to be sealed can be determined according to actual needs, and its general depth matches the protruding end of the plugging head 2. During stamping, the stamping mechanism 6 is used to stamp the plugging head 2, and the sealing block 3 is stamped into the sealing channel 1 to be sealed. Then, the plugging head 2 is fixed by the fastening bolt 4.

[0016] For facilitating the stamping of the plugging head 2, the stamping mechanism 6 includes a housing 61. A stamping port corresponding to the plugging head 2 is opened at the front end of the housing 61. A stamping piston 62 is arranged inside the housing 61. One end of the stamping piston 62 extends out of the stamping port. A stamping chamber 63 is arranged above the stamping piston 62 inside the housing 61. The stamping chamber 63 is communicated with a hydraulic pump 8 through a sealing pipe 7 above.

[0017] In the actual use of the present invention, the flexible sealing material used is rubber. Without considering cost issues, silica gel can be used instead of rubber as the flexible sealing material. The main purpose is to seal the leak hole under the action of the plugging head 2 during sealing and plugging to achieve the purpose of preventing leakage.

[0018] In order to better cooperate with the stamping mechanism 6 so that the stamping mechanism 6 can better apply pressure to the plugging head 2, the stamping piston 62 is set in a convex shape structure to apply a downward punching force to the plugging head 2 during its operation.

[0019] In order to prevent the sealing block 3 from being punctured by the sharp bottom end of the plugging head 2 when the plugging head 2 of the present invention is sealing, therefore, the bottom end of the plugging head 2 has an arc transition.

[0020] In order to better stabilize the stability of the plugging head 2 after sealing, the number of the fastening bolts 4 is two, and they are respectively placed at the left and right ends of the plugging head 2.

[0021] Specifically, when the present invention seals the leakage channel, a corresponding channel to be sealed is dug at the place to be sealed. During stamping, the stamping mechanism is used to stamp the plugging head, and the sealing block is stamped into the channel to be sealed. Then, the plugging head is stabilized through the fastening bolts. The present invention has the advantages of convenient leak plugging, high leak plugging efficiency and easy operation.

[0022] The above has described in detail the embodiments of the present invention in conjunction with the drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principles and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
