Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and more specifically, to a pipeline water accumulation detection device and pipeline water accumulation detection equipment. Background Technology

[0002] Sprinkler pipes are fire protection facilities. In the event of a fire in certain locations (such as data centers), water can be sprayed onto specific areas (such as the computer room where the fire occurs) through these sprinkler pipes. Under normal circumstances (when not in a fire), there should be no water inside the sprinkler pipes.

[0003] During routine fire protection maintenance, there is a risk of water accumulation in the sprinkler pipes directly above the server racks after construction is completed. Currently, the common method to check for water accumulation is to remove the sprinkler pipes. However, this method is extremely risky because: 1. The operators are unpredictable; 2. The sprinkler pipes' location directly above the server racks makes operation inconvenient; 3. The large number of sprinkler pipes means that personnel may make mistakes during prolonged periods of high-intensity operation, leading to water entering the server racks or heavy objects (such as sprinkler heads, wrenches, spray guns, hoses, etc.) falling on the racks, ultimately causing service outages and affecting production.

[0004] To minimize the number of sprinkler pipes that need to be removed, it's best to confirm whether there is water inside the pipes before removal. If there is no water, removal can be skipped, and only the pipes containing water should be dismantled. However, currently, there is a lack of methods and equipment to detect water accumulation inside pipes without removing them. Utility Model Content

[0005] The purpose of this invention is to provide a pipe water accumulation detection device and a pipe water accumulation detection equipment, which can determine whether there is water in the sprinkler pipe without dismantling the sprinkler pipe, thereby reducing the number of sprinkler pipes to be dismantled and reducing operational risks.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] As disclosed in the background section, existing methods for inspecting sprinkler pipes typically require disassembling the sprinkler heads for inspection, which is time-consuming and labor-intensive. This is especially true in large systems, where disassembly and reinstallation of sprinkler pipes can lead to prolonged downtime and increased maintenance costs. Furthermore, traditional methods struggle to monitor the status of sprinkler pipes in real time, potentially resulting in delayed problem detection and impacting normal system operation.

[0039] Existing technologies also include detection devices for detecting the internal conditions of pipelines. However, these devices can only detect specific points on the pipeline, are inconvenient to move, and are prone to missing detections, resulting in poor detection performance.

[0040] To address the aforementioned problems, this utility model provides a novel pipe water accumulation detection device 100 and pipe water accumulation detection equipment. The specific structure and working principle of the pipe water accumulation detection device 100 and equipment will be described in detail below.

[0041] See Figures 1 to 3 This utility model provides a pipe water accumulation detection device 100 and a pipe water accumulation detection equipment, which can determine whether there is water in the sprinkler pipe without dismantling the sprinkler pipe, thereby reducing the number of sprinkler pipes to be dismantled and reducing operational risks. Furthermore, it is easy to move and can detect every location in the sprinkler pipe, effectively avoiding missed detections.

[0042] This utility model provides a pipe water accumulation detection device 100, including a connecting bracket 110, a sliding head 130, a detection head 150, and a holding rod 170. The connecting bracket 110 is configured to be fastened to the outside of the pipe 200 to be tested. Two sliding heads 130 are disposed at both ends of the connecting bracket 110 and are configured to roll against the outer surface of the pipe 200 to be tested, and the connecting bracket 110 can move along the pipe 200 to be tested through the two sliding heads 130. The detection head 150 is disposed on the connecting bracket 110 and is configured to detect the water accumulation in the pipe 200 to be tested. One end of the holding rod 170 is connected to one of the sliding heads 130 and is configured to drive the sliding head 130 to roll relative to the pipe 200 to be tested.

[0043] In actual testing, the connecting bracket 110 can be rolled and fastened to the pipe 200 under test using two sliding heads 130. The probe 150 is used to detect the water accumulation inside the pipe. By holding the handle 170, the sliding heads 130 can be rolled to adjust the position of the connecting bracket 110, thereby achieving detection at different locations. Therefore, this embodiment of the invention can detect the internal water accumulation of the entire pipe from the outside, thus determining whether there is water inside the sprinkler pipe without disassembling it, thereby reducing the number of sprinkler pipes to be removed and reducing operational risks. Furthermore, the method of using the sliding heads 130 to roll and adjust their position is convenient to move and can detect every location of the sprinkler pipe, effectively avoiding missed detections.

[0044] It should be noted that the pipe 200 to be tested here can be a sprinkler pipe, which can be used in household, industrial, agricultural irrigation, and fire protection systems. This sprinkler pipe includes sprinkler heads at the ends and a pipe body, which may include one or more vertical pipe sections and one or more horizontal pipe sections. In this embodiment, the connecting bracket 110 is fastened to the pipe body by two sliding heads 130, thereby enabling the detection of water accumulation inside the pipe body. Specifically, the detection is mainly performed on the water accumulation in the horizontal sections.

[0045] It should also be noted that the probe 150 here can be an acoustic sensor. The acoustic sensor emits sound waves, which propagate and are reflected within the sprinkler pipe. The presence of water alters the propagation speed and reflection characteristics of the sound waves. By analyzing the changes in the reflected signal, the presence of water within the sprinkler pipe can be determined. In actual testing, the probe 150 communicates with the main unit of the device, either via a wired connection or a wireless connection. The detection process is initiated, and the sensor begins collecting data. The signal processing unit in the main unit analyzes the collected data to determine the state within the sprinkler pipe. The results are displayed on the main unit and output through the alarm system, informing the user of the current water status within the sprinkler pipe.

[0046] In some embodiments, the connecting bracket 110 includes a support rod 111 and fixed rods 113 disposed at both ends of the support rod 111. The support rod 111 is configured to correspond to the pipe 200 to be tested at intervals. A probe 150 is disposed on the support rod 111. The two fixed rods 113 are bent relative to the support rod 111, and sliding heads 130 are respectively disposed at the ends of the two fixed rods 113 away from the support rod 111. Specifically, the connecting bracket 110 is U-shaped and surrounds the pipe 200 to be tested. The two sliding heads 130 are respectively disposed at the bent portions of the two fixed rods 113, so that the connecting bracket 110 can be fastened to the outside of the pipe 200 to be tested. Furthermore, the two fixed rods 113 are symmetrically distributed at both ends of the support rod 111, so that the two sliding heads 130 can symmetrically abut against the outer surface of the pipe 200 to be tested, thereby preventing them from falling off.

[0047] Furthermore, each sliding head 130 includes a first pulley 131, a rotating shaft 133, and a second pulley 135. The rotating shaft 133 is connected to the connecting bracket 110. The first pulley 131 and the second pulley 135 are rotatably arranged on the rotating shaft 133 at intervals, and simultaneously roll against the surface of the pipe 200 to be tested. The holding rod 170 is connected to one end of the rotating shaft 133. Specifically, the first pulley 131 and the second pulley 135 have the same outer diameter and are spaced apart, which ensures that the first pulley 131 and the second pulley 135 are firmly held against the outer surface of the pipe 200 to be tested, effectively preventing them from falling off. Moreover, the arrangement of the first pulley 131 and the second pulley 135 can also be applied to pipes 200 of different sizes to be tested.

[0048] During actual installation, the two sliding heads 130 can roll against the top and bottom surfaces of the pipe to be tested 200, respectively, and the probe head 150 can correspond to the side of the pipe to be tested 200. At the same time, the holding rod 170 is connected to the sliding head 130 on the bottom side.

[0049] In some embodiments, the extending direction of the rotating shaft 133 is perpendicular to the moving direction of the connecting bracket 110. Specifically, the rotating shaft 133 extends horizontally and is perpendicular to the extending direction of the pipe 200 to be tested, thereby enabling the first pulley 131 and the second pulley 135 to roll against the pipe 200 to be tested. Simultaneously, the first pulley 131 and the second pulley 135 have identical structures, and the midpoint of the line connecting the centers of the first pulley 131 and the second pulley 135 of the two sliding heads 130 overlaps with the diameter direction of the pipe 200 to be tested. That is, from the cross-sectional view of the pipe 200 to be tested, the first pulley 131 and the second pulley 135 are symmetrical along the vertical diameter direction of the pipe 200 to be tested, ensuring the rolling engagement effect of the first pulley 131 and the second pulley 135 with the pipe 200 to be tested.

[0050] It should be noted that the first pulley 131 and the second pulley 135 here are both conventional pulley structures, that is, the outer ring rolls and the inner ring is fixed through bearings. For details, please refer to existing rolling pulleys.

[0051] See Figure 2 and Figure 4 In some embodiments, the end of the gripping rod 170 is sleeved on the rotating shaft 133, and a fixing member 137 is detachably provided on the rotating shaft 133. The fixing member 137 is configured to fix the rotating shaft 133 and the gripping rod 170. Specifically, the fixing member 137 is a quick-release structure that can switch between a tightened state and a loosened state. When the fixing member 137 is in the tightened state, it can provide a fastening force along the axial direction of the rotating shaft 133, which can keep the rotating shaft 133 and the gripping rod 170 relatively fixed. At this time, the gripping rod 170 can better drive the sliding head 130 to roll. When the fixing member 137 is in the loosened state, it can release the fastening limit on the gripping rod 170, so that the angle between the gripping rod 170 and the rotating shaft 133 can be freely adjusted, which is convenient for switching between vertical pipe sections and horizontal pipe sections. After the adjustment is completed, the fixing member 137 can be tightened again to fix the gripping rod 170.

[0052] Furthermore, the end of the gripping rod 170 is provided with a mounting hole 171, and the end of the rotating shaft 133 is correspondingly fitted into the mounting hole 171. The diameter of the mounting hole 171 is larger than the diameter of the rotating shaft 133, and the width of the fixing member 137 is larger than the diameter of the mounting hole 171. The fixing member 137 is configured to abut and fix the gripping rod 170. Specifically, the fixing member 137 can be a nut, and the end of the rotating shaft 133 is provided with threads, so that the fixing member 137 and the end of the rotating shaft 133 can be threadedly engaged. At the same time, a stop ring 139 is also provided on the rotating shaft 133. The outer diameter of the stop ring 139 is larger than the diameter of the mounting hole 171, thereby stopping the gripping rod 170 and preventing the gripping rod 170 from interfering with the rotation of the first pulley 131 or the second pulley 135. The fixing member 137 can be provided with a lug for easy hand-tightening, thereby facilitating the tightening or loosening of the fixing member 137.

[0053] In some embodiments, the gripping rod 170 includes a telescopic part 173 and a gripping part 175. The gripping part 175 is connected to one end of the telescopic part 173, and the other end of the telescopic part 173 is connected to a rotating shaft 133. The telescopic part 173 is configured to extend and retract, causing the gripping part 175 to move closer to or away from the rotating shaft 133. Specifically, the gripping part 175 is provided with anti-slip textures. The telescopic part 173 can be a structure in which multiple telescopic cylinders are sequentially nested to achieve the telescopic function. The top end of the telescopic part 173 is provided with a mounting hole 171, which facilitates assembly onto the rotating shaft 133. By providing the telescopic part 173, it is possible to detect pipes 200 at different heights, improving its applicability and eliminating the need for climbing operations.

[0054] See Figure 5 and Figure 6 In some embodiments, telescopic structures 190 are also provided at both ends of the support rod 111. The telescopic structures 190 are connected to the fixed rods 113 and are configured to telescopically adjust the distance between the two fixed rods 113. Specifically, the fixed rods 113 and the support rod 111 are movably connected through the telescopic structure 190. By adjusting the telescopic structure 190, the gap distance between the two fixed rods 113 can be adjusted, thereby making it suitable for test pipes 200 of different diameters and further improving its applicability.

[0055] Furthermore, the telescopic structure 190 includes an elastic telescopic member 191, one end of which is connected to the support rod 111 and the other end to the fixed rod 113. The elastic telescopic member 191 is configured to provide a spring force toward the other fixed rod 113. Specifically, the elastic telescopic member 191 can be a compression spring that provides an inward spring force, thereby ensuring that the sliding head 130 can roll against the outer surface of the pipe 200 under test. When testing a large-sized pipe 200, the two fixed rods 113 can be pulled apart by external force to accommodate the large-sized pipe 200. Furthermore, protrusions or spray nozzles on the pipe 200 can be avoided by pulling apart the fixed rods 113.

[0056] This utility model embodiment also provides a pipe water accumulation detection device, including a main unit and the aforementioned pipe water accumulation detection device 100. The pipe water accumulation detection device 100 includes a connecting bracket 110, a sliding head 130, a detection head 150, and a holding rod 170. The connecting bracket 110 is configured to be fastened to the outside of the pipe 200 to be tested. Two sliding heads 130 are disposed at both ends of the connecting bracket 110 and are configured to roll against the outer surface of the pipe 200 to be tested, and the connecting bracket 110 can move along the pipe 200 to be tested through the two sliding heads 130. The detection head 150 is disposed on the connecting bracket 110 and is configured to detect the water accumulation in the pipe 200 to be tested. One end of the holding rod 170 is connected to one of the sliding heads 130 and is configured to drive the sliding head 130 to roll relative to the pipe 200 to be tested. The main unit is communicatively connected to the detection head 150.

[0057] Furthermore, the main unit is equipped with a signal processing unit, a display screen, and an alarm. The probe 150 is an acoustic sensor. The main unit can connect to the probe 150 via a wire or wirelessly. During actual testing, the detection process begins, and the probe 150 starts collecting data. The signal processing unit in the main unit analyzes the collected data to determine the state within the sprinkler pipe. The results are output through the main unit's display screen and alarm to inform the user of the current water level in the sprinkler pipe.

[0058] In summary, the pipe water accumulation detection device 100 and equipment provided in this embodiment of the present invention have two sliding heads 130 disposed at both ends of the connecting bracket 110, which can roll against the outer surface of the pipe 200 to be tested. Thus, the connecting bracket 110 can be engaged with the outside of the pipe 200 through the two sliding heads 130, and can move along the pipe 200 through the two sliding heads 130. A detection head 150 is disposed on the connecting bracket 110, thereby detecting the water accumulation inside the pipe 200. A holding rod 170 is connected to one of the sliding heads 130, thereby driving the sliding head 130 to roll. In actual testing, the connecting bracket 110 can be rolled and engaged with the pipe 200 through the two sliding heads 130, and the detection head 150 can be used to determine the water accumulation inside the pipe. By holding the holding rod 170, the position of the connecting bracket 110 can be adjusted, thereby achieving detection at different positions. Compared to existing technologies, this utility model embodiment can detect the internal water accumulation of the entire pipeline from the outside, thereby determining whether there is water inside the sprinkler pipe without dismantling the sprinkler pipe, thus reducing the number of sprinkler pipes to be dismantled and lowering operational risks.

[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
