Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection device for water conservancy and hydropower construction. Background Art

[0002] Water conservancy and hydropower refers to the use of water resources to develop water conservancy projects and hydropower projects to achieve comprehensive utilization for purposes such as irrigation, water supply, flood control, and power generation. In water conservancy and hydropower construction, pipelines are an indispensable and important part. Pipelines play a key role in transporting and discharging water resources in water conservancy and hydropower projects. Since most of the pipelines arranged on the construction site are relatively complex, pipeline connection devices are required to connect the pipelines.

[0003] However, the existing pipeline connection device has the risk of water seepage during the connection process. If the staff does not find it in time, safety accidents are likely to occur. At the same time, no protective device is arranged at the pipeline connection, making the connection part relatively fragile. In view of this, we propose a pipeline connection device for water conservancy and hydropower construction. Utility Model Content

[0009] Preferably, a rotation groove is provided on the top wall of the positioning and fixing block, a bearing is installed in the rotation groove, and a threaded rod is arranged in the bearing.

[0010] Preferably, a threaded hole is provided on the outer wall of the internal threaded protective sleeve, and the threaded rod is arranged in the threaded hole at a corresponding position.

[0011] Preferably, a receiving cavity is provided on the inner wall of the internal thread protective sleeve, and the size of the receiving cavity is larger than the size of the positioning and fixing block.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model inserts the end of the pipe on the connecting pipe so that it is located inside the internal threaded protective sleeve, and the threaded rod is twisted to drive the positioning fixing block to descend, thereby realizing the positioning of the pipe connection, and under the protection of the V-shaped rubber pad, damage to the outer wall of the pipe is avoided during the positioning process. Since the pipe needs to be inserted in the internal threaded protective sleeve for connection, the internal threaded protective sleeve protects the connection of the pipe to prevent it from being damaged by external collision. At the same time, the arrangement of the detection cavity is conducive to monitoring when water leakage occurs in the two connecting pipes, and cooperates with the alarm to complete the alarm, so as to achieve the purpose of reminding the staff, which is conducive to timely maintenance and avoidance of leakage accidents.

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-3As shown, the pipeline connection device for water conservancy and hydropower construction proposed by the utility model includes an internal threaded protective sleeve 1, and two pipes 2 are symmetrically arranged inside the internal threaded protective sleeve 1, which is convenient for connecting the two pipe interfaces; two first external threaded rings 3 are symmetrically sleeved on the outer ring surfaces of the two pipes 2, and the second external threaded ring 4 is fixedly installed on the side wall of one first external threaded ring 3, and is arranged in a threaded groove opened on the side wall of the other first external threaded ring 3, and the connection of the two pipes 2 is completed through the threaded groove. The two first external threaded rings 3 are also connected to the internal threaded protective sleeve 1 by threads, which is convenient for replacing the first external threaded ring 3 when leakage occurs, and under the arrangement of the second external threaded ring 4, the sealing of the joint of the two first external threaded rings 3 is improved, and the risk of leakage at the pipeline connection is reduced.

[0021] Furthermore, a detection component 5 for monitoring leakage is provided in the internal threaded protective sleeve 1. The detection component 5 includes a detection cavity 51. The detection cavity 51 is arranged on the inner surface wall of the internal threaded protective sleeve 1 and is located at the joint of the two first external threaded rings 3, which is conducive to collecting the liquid at the leakage; the liquid level sensor 52 is fixedly installed on the inner wall of the detection cavity 51 to monitor the liquid level in the detection cavity 51. The alarm 7 is fixedly installed on the top wall of the internal threaded protective sleeve 1 and is electrically connected to the liquid level sensor 52. When the liquid level in the detection cavity 51 reaches the liquid level sensor 52, the liquid level sensor 52 cooperates with the alarm 7 to sound an alarm, thereby reminding the staff to check and repair the device in time to avoid subsequent serious leakage accidents.

[0022] Furthermore, a positioning assembly 6 is installed on the internal threaded protective sleeve 1 for fixing the position of the pipe connection. The positioning assembly 6 includes a positioning and fixing block 61. The positioning and fixing block 61 is arranged inside the internal threaded protective sleeve 1. The V-shaped groove at the bottom of the positioning and fixing block 61 can clamp and limit the outer wall of the pipe. The V-shaped rubber pad 62 is adapted to the V-shaped groove and is fixedly installed in the V-shaped groove, which is beneficial to protect the outer wall of the pipe during the process of the positioning and fixing block 61 clamping the pipe, and avoids damage to the outer wall of the pipe during the clamping process; the bearing 63 is installed in the rotation groove opened on the top wall of the positioning and fixing block 61, and the bottom end of the threaded rod 64 penetrates The threaded hole on the internal threaded protective sleeve 1 is passed through and arranged in the bearing 63. At the same time, it is also connected to the outer ring surface of the bearing 63. The bearing 63 assists the threaded rod 64 to rotate, which is conducive to adjusting the height of the positioning and fixing block 61. During the replacement of the connecting pipe 2, it is convenient to adjust the positioning and fixing block 61 to the storage cavity on the inner wall of the internal threaded protective sleeve 1 to avoid affecting the staff to remove the connecting pipe 2 from the internal threaded protective sleeve 1; during the connection process, the pipeline needs to be plugged into the connecting pipe 2, so that the interface end of the pipeline is located in the internal threaded protective sleeve 1, and under the action of the internal threaded protective sleeve 1, the purpose of protecting the pipeline interface is achieved.
