Description

Technical Field

[0001] The utility model belongs to the technical field of circulating pipelines and relates to a cooling pipeline structure and a cooling water circulating pipeline. Background Art

[0002] It is very common to use water circulation cooling for test. Take the retarder test as an example. The retarder test requires a large flow of cooling circulating water to cool the heat generated by the retarder in time. Due to structural reasons, there must be a rubber tube connection part in the cooling pipeline. However, the rubber tube will be damaged due to quality problems or long-term use.

[0003] If the rubber tube is damaged, a large flow of cooling water will overflow into the test room, damaging the test equipment and posing a great risk of electric shock. The existing protection measures are limited to the rubber tube being damaged, the cooling circulating water overflowing into the ditch and triggering the water level alarm probe alarm, the use of internal circulation cooling, the flow reduction alarm being triggered after the cooling water flows dry, and the on-duty personnel's inspection and discovery. There is a lack of the most direct and timely pipe burst monitoring and alarm.

[0004] Existing rubber hose technologies all involve strengthening the pipeline itself to ensure the strength of the rubber hose and reduce the probability of its bursting. However, bursting of the hose cannot be avoided, and there is no effective means to monitor damage. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing pipeline structure in the prior art has no effective means to monitor the damage of the rubber tube and cannot avoid the damage of the rubber tube. When the rubber tube is damaged, the cooling water will overflow into the ditch and there is a risk of electric shock. A cooling pipeline structure and a cooling water circulation pipeline are provided.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cooling pipeline structure comprises an inner layer pipeline, an outer layer pipeline is sleeved outside the inner layer pipeline, and there is a gap between the inner layer pipeline and the outer layer pipeline;

[0008] A monitoring component is arranged on the outer pipeline, and the monitoring component is used to monitor the pressure between the inner pipeline and the outer pipeline.

[0009] The further improvement of the utility model is:

[0010] The monitoring component comprises a quick-insert structure, and the quick-insert structure is connected to a pressure sensor.

[0011] It also includes a pressure alarm mechanism, which is connected to the pressure sensor.

[0012] The quick-insert structure is connected to the pressure sensor via an air pipe.

[0013] The quick-insert structure is a pipeline quick-insert connector.

[0014] The inner layer pipeline and the outer layer pipeline are an integrated structure.

[0015] The inner layer pipeline and the outer layer pipeline are bonded.

[0016] The inner layer pipeline and the outer layer pipeline are both rubber tubes.

[0017] A cooling water circulation pipeline comprises the cooling pipeline structure according to any one of claims of the utility model.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model discloses a cooling pipeline structure, which has a double-layer structure, including an inner pipeline and an outer pipeline, and there is a gap between the inner pipeline and the outer pipeline, and the gap forms a sandwich space. When water flows through the inner pipeline, the inner pipeline plays a major role in bearing pressure. If the inner pipeline ruptures, the cooling water will directly enter the sandwich, and the sandwich provides a buffer space for overflowing cooling water. A monitoring component installed on the outer pipeline will monitor the pressure in the sandwich space in real time. When the overflowing water enters the sandwich, the pressure value monitored by the monitoring component changes, and the staff takes timely remedial measures according to the pressure change. Through the buffering of the sandwich space, the cooling water will not flow out directly, will not cause electric shock, and will not cause damage to the experimental equipment. The device can effectively monitor the running condition of the pipeline in the test of the retarder, discover abnormal phenomena in time, and prevent the pipeline from bursting.

[0020] Furthermore, the utility model also includes an alarm mechanism. The pressure alarm mechanism is connected to the pressure sensor. The upper limit value of the pressure can be directly set at the alarm mechanism. When the monitored pressure exceeds the upper limit value, the alarm mechanism will sound an alarm, so that abnormal situations can be discovered more promptly and quickly.

[0021] Furthermore, in the present invention, the inner layer pipeline and the outer layer pipeline are an integrated structure, and the overall connection is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] The utility model is further described in detail below with reference to the accompanying drawings:

[0034] See also Figures 1 to 3 The utility model discloses a cooling pipeline structure, which can effectively prevent the cooling water from flowing into the test room and causing damage to the equipment when the rubber tube is broken, and can timely discover the initial rupture of the pipeline to avoid greater damage and loss. The structure specifically includes the following:

[0035] See also Figure 1 to Figure 2 The utility model discloses a cooling pipeline structure, including an inner pipeline 1, an outer pipeline 2 is sleeved outside the inner pipeline 1, and there is a gap between the inner pipeline 1 and the outer pipeline 2; a monitoring component is arranged on the outer pipeline 2, and the monitoring component is used to monitor the pressure between the inner pipeline 1 and the outer pipeline 2.

[0036] Furthermore, in this embodiment, the gap between the inner pipe 1 and the outer pipe 2 forms an interlayer space. When the inner pipe 1 ruptures, the cooling water will not directly enter the test room. The interlayer space will provide a buffer space for the cooling water, reserving time for the staff to take remedial measures and avoiding greater losses.

[0037] Furthermore, in this embodiment, the inner layer pipeline 1 and the outer layer pipeline 2 can be an integrated structure or can be bonded. This embodiment does not limit the specific connection method of the inner layer pipeline 1 and the outer layer pipeline 2, as long as the normal operation of the inner layer pipeline 1 and the outer layer pipeline 2 can be achieved.

[0038] Furthermore, in this embodiment, the inner layer pipeline 1 and the outer layer pipeline 2 are both rubber pipelines.

[0039] Furthermore, in this embodiment, the specific structure of the monitoring component is:

[0040] The monitoring component includes a quick-plug structure 3, which is installed on the side wall of the outer pipeline 2. The quick-plug structure 3 is connected to the interlayer space. The quick-plug structure 3 is connected to the pressure sensor using an air pipe. The pressure sensor is mainly used to measure the pressure value of the empty layer between the inner pipeline 1 and the outer rubber monitoring pipeline 2. The pressure sensor signal is connected to the test bench measurement channel and configured to activate the pressure alarm upper limit. If the inner pipeline 1 ruptures, cooling water will enter the interlayer space and the pressure in the interlayer space will rise. When the pressure value exceeds the set upper limit, an alarm is triggered to promptly detect the existence of abnormal conditions.

[0041] Furthermore, in this embodiment, the quick-insert structure 3 is a pipeline quick-insert connector.

[0042] The embodiment of the utility model further discloses a cooling water circulation pipeline. When the retarder needs to be tested, the cooling pipeline structure in the embodiment is installed on the circulation pipeline to test the retarder.

[0043] See also Figure 3 , the working principle of this embodiment is:

[0044] The cooling pipeline structure disclosed in the embodiment of the utility model is installed on the circulation pipeline used to test the retarder. After the arrangement is completed, the water flow test is started.

[0045] During the test, cooling water 4 flows inside the inner layer pipeline 1, the inner layer rubber main pipeline 1 provides the main load-bearing, the outer layer pipeline 2 provides auxiliary load-bearing, and the quick-insert structure 3 is connected to the pressure sensor using an air pipe. The pressure sensor monitors the pressure value of the air layer between the inner layer pipeline 1 and the outer layer pipeline 2 in real time. The pressure sensor signal is connected to the test bench measurement channel, and the upper limit value of the activation pressure alarm is configured;

[0046] When the inner layer pipeline 1 is not damaged, the pressure sensor measures the pressure of the air layer between the inner layer pipeline 1 and the layer pipeline 2 through the quick-insert structure 3, which is basically 0Kpa (using a non-absolute pressure sensor);

[0047] When the inner pipeline 1 is damaged, the empty layer between the inner pipeline 1 and the outer pipeline 2 will be instantly filled with cooling water 4, and the pressure will increase sharply, triggering the test bench alarm pressure alarm upper limit value. At this time, the outer pipeline 2 provides the main bearing force to avoid a large amount of cooling water overflow, and triggers the alarm to remind the rubber tube of damage, realizing the most direct and timely rubber tube damage alarm, and preventing equipment damage and electric shock risks caused by pipe explosion.

[0048] This device provides a buffer time for overflowing cooling water through the interlayer space between the inner pipe 1 and the outer pipe 2, and cooperates with the monitoring of the pressure sensor to issue an alarm, so that the staff can take remedial maintenance measures in time to avoid the entire pipeline from bursting, causing damage to the equipment and the risk of electric shock.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
