Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid leakage detection equipment, in particular to a four-way branch device for a liquid leakage induction line. Background Art
[0002] Traditional water and oil leak detection systems are in high demand in industries such as data centers, petroleum and petrochemicals, and power grids. Existing leak detection and positioning devices typically use a single induction line laid throughout the environment to be detected, with each line requiring a corresponding positioning controller. This wiring method is not only limited by the length of the induction line and cannot meet the wiring requirements of complex spaces, but also requires multiple induction lines and positioning controllers when laying out in large spaces, resulting in complex induction line wiring and significantly increasing installation costs.
[0003] Therefore, there is an urgent need for a detection device that can connect multiple wires into an induction loop. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model proposes a four-way branch device for leakage sensing lines, which can facilitate the connection of multiple leakage sensing lines with the positioning controller to form a longer sensing loop to meet the user's topological application in specific scenarios.

The circuit board is arranged in the wiring cavity. The box body is provided with a through hole. The circuit board is provided with at least four groups of sensing line interfaces. Each group of the sensing line interfaces includes four wiring points. The two wiring points of any two adjacent groups of the sensing line interfaces are connected to each other.

[0008] A further technical solution of the present invention is that the number of the through holes is four and they are arranged opposite to each other in pairs.
[0009] A further technical solution of the present invention is that the number of the through holes is four and the angle between two adjacent through holes is 90°.
[0010] A further technical solution of the present invention is that the circuit board is configured as a single-sided board and a double-sided board.
[0011] A further technical solution of the present invention is that each group of the sensing line interfaces is arranged close to the corresponding through holes.
[0012] A further technical solution of the present invention is that a cable gland is passed through the through hole.
[0013] A further technical solution of the present invention is that the box body includes a detachable upper cover and a base.
[0014] Compared with the prior art, the utility model has the following advantages:

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] 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., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0025] Each leakage sensing line in the leakage detection usually includes four wires, which are connected in pairs to form two independent electrical circuits. Each circuit is composed of a specific pair of wires. When liquid leaks, the conductivity of the liquid causes the two circuits to be connected, thereby sensing an alarm. Figure 1 As shown in the figure, R-1 and G-2 are connected to form a sensing line loop, and Y-3 and B-4 are connected to form a sensing line loop. The typical sensing line length is 50 meters. When the sensing line detects an alarm, the alarm location is returned: 50. The detection range of a single sensing line is very limited and cannot meet the wiring requirements of larger or more complex sites.
[0026] like Figures 2 to 4As shown, the embodiment of the present utility model discloses a four-way branch device for liquid leakage sensing lines, including a box body and a circuit board. The interior of the box body is hollow to form a wiring cavity, the circuit board is arranged in the wiring cavity, the box body is provided with a through hole, and the circuit board is provided with at least four groups of sensing line interfaces, each group of the sensing line interfaces includes four wiring points, and the two wiring points of any two adjacent groups of the sensing line interfaces are connected to each other. The sensing lines and positioning controller connecting lines to be connected are passed through the through holes into the box body and connected to the circuit board, so that the wires in the multiple sensing lines are connected to each other to form two complete loops to achieve detection. Since the two wiring points of any two adjacent groups of the sensing line interfaces are connected to each other, the two wiring points of each group of sensing line interfaces are connected to the sensing line interface on one side, and the other two wiring points are connected to the sensing line interface on the other side; when an input line of a positioning controller is connected to a sensing line interface, and three leakage sensing lines are connected to the other three sensing line interfaces, the following can be obtained. Figure 4 The connection relationship shown in the figure forms two groups of loops, one group is connected between G1-2 and R2-1, and B1-4 is connected to Y2-3; the other group is connected between G2-2 and R3-1, and B2-4 is connected to Y3-3. The R1-1 to G3-2 wires form a 150-meter loop, and the Y1-3 to B3-4 wires form a 150-meter loop. When the output 1 sensing line end 3 sensing line end alarms, the return position is 150, thus forming a longer sensing line loop, which can adapt to different leakage detection scenarios, reduce the length of the sensing line consumption, and save laying costs.
[0027] Those skilled in the art will appreciate that the structure of the connection point is a welding point, and may also be adjusted to a connection structure such as a plug-in connector, a tightening screw, etc. according to needs.
[0028] In this embodiment, the number of the through holes is not less than two. Those skilled in the art will appreciate that the number of through holes can be two, three, or four, so as to facilitate insertion of multiple sensing wires into the box. The number of the through holes is four, and they are arranged in pairs opposite to each other.
[0029] In this embodiment, there are four through holes and the angle between two adjacent through holes is 90°. That is, the sensing lines extend from all four sides of the box body, which can further expand the coverage of the sensing lines and realize multi-angle laying of the sensing lines.
[0030] In this embodiment, the circuit board is configured as a single-sided board or a double-sided board, and those skilled in the art can select the one according to actual needs.
[0031] In this embodiment, each group of the sensing line interfaces is disposed close to the corresponding through holes, so that the sensing lines can be quickly connected to the wiring points after being inserted.
[0032] In this embodiment, a cable gland is provided in the through hole; the cable gland can fix sensing wires of various specifications and also prevent water intrusion.
[0033] In this embodiment, the box body includes a detachable upper cover and a base. It is understood that the shape of the upper cover is not limited to a flat plate. The upper cover can also be a shell that is the same as the base, and the upper cover and the base are fixed to each other by screws, snaps, etc. to form a relatively closed wiring cavity.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
