Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy pipelines, in particular to a pipeline protection device. Background Art
[0002] The development of water conservancy projects is crucial for irrigation, drainage, etc., and pipes are basically used to transport water in water conservancy projects. Therefore, the protection of pipelines is particularly important and it happens a lot in real life.
[0003] At present, water conservancy pipelines are generally buried underground and protected by soil layers. Due to the need to avoid low-temperature ice blockage inside the pipeline, the pipeline is usually buried deep, and the initial excavation and subsequent backfilling are difficult. In addition, there is a lack of warning reminders for buried pipelines, which are easily damaged by subsequent excavation and construction. Utility Model Content
[0004] The present disclosure relates to a pipeline protection device, which solves the problem that existing water conservancy pipelines are generally buried underground and protected by soil layers. Since it is necessary to avoid low-temperature icing and blockage inside the pipeline, the pipeline is usually buried at a deep depth, and the early construction excavation and later backfilling are difficult. In addition, there is a lack of warning reminders for buried pipelines, which makes them easy to be damaged by later excavation construction.
[0005] In a first aspect of the present disclosure, a pipeline protection device is provided, which specifically includes: a protective lower trough; a protective upper cover is installed on the top of the protective lower trough, and a lower protective shell is installed inside the protective lower trough; an upper protective shell is connected to the top of the lower protective shell, and the upper protective shell is located inside the protective upper cover.
[0006] Furthermore, the two ends of the top of the lower protective shell are arranged with limit pins, and the two ends of the bottom of the upper protective shell are arranged with sockets. The limit pins are inserted into the sockets provided in the upper protective shell. The limit pins are plugged into the sockets provided in the upper protective shell, and the limit pins are plugged into the sockets to limit the lower protective shell and the upper protective shell, so that the pipeline is located in the circular channel formed by the lower protective shell and the upper protective shell.
[0007] Furthermore, positioning protrusions are equidistantly provided on both sides of the bottom of the lower protective shell, and positioning grooves are equidistantly provided on the left and right inner sides of the protective lower groove. The positioning protrusions are inserted into the positioning grooves provided in the protective lower groove. The positioning protrusions and the positioning grooves are inserted and matched to achieve a limiting effect on the lower protective shell.
[0008] Furthermore, slots are provided at two ends of the top of the protective lower slot, and two ends of the bottom of the protective upper cover are inserted into the slots provided in the protective lower slot.
[0009] Furthermore, the top of the upper protective shell is symmetrically provided with guide columns, and the top of the protective upper cover is symmetrically provided with guide holes. The guide columns penetrate the guide holes provided in the protective upper cover, and the guide columns are plugged into and matched with the guide holes to limit the protective upper cover.
[0010] Furthermore, a spring is mounted on the outside of the guide column of the upper protective shell, the bottom of the spring is in contact with the outside of the upper protective shell, and the top of the spring is in contact with the inside of the protective upper cover. When the protective upper cover is buckled on the top of the protective lower groove, the protective upper cover applies pressure to the spring, and the upper protective shell is in close contact with the pipeline under the influence of the spring thrust, thereby clamping and fixing the pipeline, and achieving double protection effect on the pipeline through the protective lower groove and the protective upper cover.
[0011] Furthermore, the cavity between the protective lower trough and the lower protective shell is filled with a foaming agent, and an injection hole is provided on the top of the protective upper cover. The foaming agent is filled into the cavity between the protective upper cover and the upper protective shell through the injection hole. By filling the foaming agent into the internal cavity of the device, the pipeline is wrapped around and insulated, thereby achieving a heat-insulating effect on the pipeline and ensuring the constant temperature of the water flow inside the pipeline.
[0012] The utility model provides a pipeline protection device, which has the following beneficial effects:
[0013] When the utility model is in use, the limiting plug column cooperates with the plug hole to limit the lower protective shell and the upper protective shell, so that the pipeline is located in the circular channel formed by the lower protective shell and the upper protective shell, which has a protective effect on the pipeline and prolongs the service life of the pipeline; the positioning protrusion cooperates with the positioning groove to limit the lower protective shell and prevent the lower protective shell from being displaced; the guide column cooperates with the guide through hole to limit the protective upper cover and prevent the protective upper cover from being displaced.
[0014] In addition, when the protective upper cover is buckled on the top of the protective lower trough, the protective upper cover exerts pressure on the spring, and the upper protective shell is in close contact with the pipeline under the influence of the spring thrust, which has the effect of clamping and fixing the pipeline, ensuring the stability of the pipeline state, and achieving double protection effect on the pipeline through the protective lower trough and the protective upper cover. During the later excavation construction, the excavator first contacts the protective lower trough and the protective upper cover to remind the operator to stop digging further downwards, effectively avoiding damage to the pipeline due to the later excavation construction.
[0015] In addition, by filling the foaming agent into the internal cavity of the device and wrapping the pipeline around it, the pipeline can be insulated, the constant temperature of the water flow inside the pipeline can be ensured, and the freezing of the water flow inside the pipeline due to low temperature can be effectively avoided. Shallow burial can be achieved, reducing the difficulty of construction excavation.
