[0044] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0045] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0046] like Figure 1 As shown, it is a structural diagram of an oil leakage detection and positioning device provided by an embodiment of the utility model, comprising:

[0047] Oil leakage detection and positioning network 1, connection module 2, fixing module 3 and oil leakage controller 4;

[0048] The oil leakage detection and positioning network 1 includes a plurality of oil leakage detection ropes 11, which are used to locate the oil leakage point when oil leakage occurs;

[0049] The oil leakage detection ropes 11 are arranged in parallel along a first direction and in parallel along a second direction on the same plane. The oil leakage detection ropes 11 in the first direction and the oil leakage detection ropes 11 in the second direction are cross-wound and distributed in a mesh shape to form an oil leakage detection positioning network 1. The leaked oil penetrates into the oil leakage detection ropes 11 so that the detection lines 112 in the oil leakage detection ropes 11 are connected at the oil leakage point to form a current-conducting loop.

[0050] The input end of the connection module 2 is connected to the voltage output end of the oil leakage controller 4, and a plurality of output ends are provided, and the output ends are respectively connected to the input ends of a plurality of the oil leakage detection ropes 11. The connection module 2 is used to form a current loop between the oil leakage detection ropes 11 that conduct current and the oil leakage controller 4 when oil leakage occurs, so that the oil leakage controller 4 detects the current;

[0051] The fixing module 3 is fixed to the end of the oil leakage detection rope 11 and is used to fix the oil leakage detection rope 11;

[0052] The oil leakage controller 4 is used to provide voltage and detect current, and determine the conductive oil leakage detection rope 11 in the first direction and the conductive oil leakage detection rope 11 in the second direction according to the detected current, so as to locate the oil leakage point on the oil leakage detection positioning network 1;

[0053] The first direction and the second direction in the same plane are perpendicular to each other.

[0054] In the embodiment of the utility model, an oil leakage detection rope 11 may exist on multiple planes. For example, when the oil leakage detection rope 11 is bent, it is a case that the oil leakage detection rope 11 exists on multiple planes. Figure 1 As shown, there are 5 planes in the oil leakage detection positioning network 1. For any plane, if the first direction is the horizontal direction, the second direction is the vertical direction perpendicular to the first direction on the same plane, and the vertical direction exists on the plane just like the horizontal direction. Each plane has a first direction and a second direction of each plane.

[0055] In the embodiment of the present utility model, Figure 1 As shown, the oil leakage detection positioning net 1 is 5 planes, and there are also oil leakage detection positioning nets 1 with 1-4 planes or single-sided oil leakage detection positioning nets 1 surrounding a cylinder. Multiple oil leakage detection positioning nets 1 can be used to perform oil leakage detection on the same device. For example, for a hexahedron, a 5-plane oil leakage detection positioning net 1 and a 1-plane oil leakage detection positioning net 1 can be used to surround the hexahedron.

[0056] In the embodiment of the utility model, there is an intersection point between two cross-wound oil leakage detection ropes 11, and the oil leakage point is sent at the intersection point. The two oil leakage detection ropes 11 corresponding to the intersection point are connected, and the two oil leakage detection ropes 11 correspond to the coordinates of the first direction and the second direction respectively, so the oil leakage point can be located. The interval between the parallel oil leakage detection ropes 11 should be as small as possible to ensure that each point can be accurately determined. For example, the gap between the parallel oil leakage detection ropes 11 is 0.

[0057] In the embodiment of the utility model, the oil leakage controller 4 provides voltage, but voltage does not necessarily mean current, such as in the case of a short circuit. Therefore, the oil leakage controller 4 provides voltage and detects current. When there is no oil leakage, the oil leakage detection rope 11 does not have a loop that can conduct current, which is equivalent to a short circuit, and no current flows through the oil leakage detection rope 11; when there is an oil leakage, the oil leakage detection rope 11 corresponding to the oil leakage point forms a loop that conducts current, and under the condition of input voltage, current is generated. When there is an oil leakage, the current of the oil leakage controller 4 outputs a current to the oil leakage detection rope 11 through the connection module 2, and the detection line 112 in the oil leakage detection rope 11 corresponding to the oil leakage point is turned on, forming a current loop with the connection module 2 and the oil leakage controller 4, generating current.

[0058] In the embodiment of the utility model, the input end of the connection module 2 has two interfaces, corresponding to the two interfaces of the voltage output end of the oil leakage controller 4. The voltage output end of the oil leakage controller 4 can output AC voltage or DC voltage. Since the oil leakage detection rope 11 can be regarded as a pure resistance device, it is only necessary to maintain a one-to-one connection between the two interfaces of the voltage output end of the oil leakage controller 4 and the two interfaces of the input end of the connection module 2. Since the actual oil leakage position is determined based on the current value, the obtained current can be positive or negative, and the current value is only used for calculation.

[0059] In the embodiment of the utility model, each output end of the connection module 2 includes two interfaces, which correspond to the two interfaces of the input end of the oil leakage detection rope 11. The two interfaces on an output end of the connection module 2 and the two interfaces on the input end of an oil leakage detection rope 11 are in a one-to-one connection relationship.

[0060] In the embodiment of the utility model, the oil leakage detection rope 11 has only an input end but no output end.

[0061] In the embodiment of the present utility model, Figure 2As shown, point P is the oil leakage point, the block hollow arrow is the flow direction of the current on the oil leakage detection rope 11 in the first direction, and the block black solid arrow is the flow direction of the current on the oil leakage detection rope 11 in the second direction. At this time, according to the current detected by the oil leakage controller 4, the length X from the oil leakage point corresponding to the oil leakage detection rope 11 in the first direction to the input end of the oil leakage detection rope 11 or the length Y from the oil leakage point corresponding to the oil leakage detection rope 11 in the second direction to the input end of the oil leakage detection rope 11 can be known, so the plane coordinates (X, Y) of the oil leakage point in the plane where it is located can be known, and thus the precise position of the oil leakage point can be known. It can also be simply understood as determining the oil leakage detection rope 11 with the on-current in the first direction, that is, a, and determining the oil leakage detection rope 11 with the on-current in the second direction, that is, b, and the intersection of a and b is the oil leakage point. a can be determined by Y, and b can be determined by X. In this way, even if the oil leakage detection rope 11 exists in multiple planes at the same time, only a and b need to be known to know the three-dimensional coordinates of the oil leakage point.

[0062] The oil leakage detection and positioning device provided by the embodiment of the utility model provides voltage and detects current through the oil leakage controller 4. When an oil leakage point occurs, the oil leakage detection rope 11 corresponding to the oil leakage point on the oil leakage detection and positioning network 1 is turned on, so that current occurs. The current returns to the oil leakage controller 4 through the connection module 2. The oil leakage controller 4 determines the oil leakage detection rope 11 that is turned on in the first direction and the oil leakage detection rope 11 that is turned on in the second direction according to the detected current, so as to locate the oil leakage point on the oil leakage detection and positioning network 1. In this way, the situation of too many winding coils is reduced by using a plurality of oil leakage detection ropes 11 in parallel to form the oil leakage detection and positioning network 1, and solves the problem that the oil leakage point occurs in the second half of the winding direction of the oil leakage detection rope 11, and the positioning is inaccurate due to too many winding coils.

[0063] like Figure 3 , Figure 4 As shown, as a preferred embodiment of the utility model, the oil leakage detection rope 11 includes: a center line 111, a detection line 112, an isolation line 113, an oil absorption expansion sleeve 114, and a limit sleeve 115;

[0064] The center line 111 is arranged at the middle part of the oil leakage detection rope 11, and plays the role of supporting the main body;

[0065] The detection lines 112 include two lines, the detection lines 112 do not intersect each other, surround the center line 111, and are used to transmit current;

[0066] The isolation lines 113 include a plurality of lines, which surround the center line 111 and are used to separate the two detection lines 112 and provide internal support for the oil absorption expansion sleeve 114;

[0067] The oil absorption expansion sleeve 114 is on the center line 111 surrounded by the isolation line 113 on the outside, and has a gap 116 between the center line 111 and the detection line 112;

[0068] The limiting sleeve 115 is sleeved on the oil absorption expansion sleeve 114 to provide external support for the oil absorption expansion sleeve 114 so as to limit the outward expansion of the oil absorption expansion sleeve 114 .

[0069] In the embodiment of the present utility model, the center line 111 and the isolation line 113 are both insulated. Figure 3 , which is a cross-sectional view of the oil leakage detection rope 11 , wherein the isolation line 113 and the center line 111 separate the two detection lines 112 .

[0070] In the embodiment of the utility model, the input ends of the two detection lines 112 constitute the input end of the oil leakage detection rope 11. The detection line 112 has no output end, which can be understood as follows. Figure 2 As shown, after the two detection lines 112 are in contact with each other because of the oil absorption expansion sleeve 114, the current flows into the input end of one detection line 112 and flows out from the output end of the other detection line 112. The current flows in the direction shown in FIG. Figure 2 As shown by the blocky hollow arrows or blocky black solid arrows in the figure.

[0071] In the embodiment of the utility model, the two detection lines 112 are the same resistance lines. When an oil leak occurs, the length of the position where the oil leak contacts the two detection lines 112 is constant, so the resistance R of the oil leak detection rope 11 corresponding to the oil leak is, where is the resistivity of the detection line 112, k is the length ratio of the detection line 112 to the oil leak detection rope 11, x is the length from the oil leak corresponding to the oil leak detection rope 11 to the input end of the oil leak detection rope 11, and S is the cross-sectional area of ​​the detection line 112; and R can be known according to Ohm's law through the voltage provided by the oil leak detector and the detected current, so the length x from the oil leak corresponding to the oil leak detection rope 11 to the input end of the oil leak detection rope 11 can be known.

[0072] In the embodiment of the utility model, the oil absorption expansion sleeve 114 will expand when absorbing oil. When not expanded, the system has an expansion sleeve because there is a gap between it and the detection line 112, so it will not contact the detection line 112. After the oil absorption expansion sleeve 114 absorbs oil and expands, the outside cannot expand outward due to the limit sleeve 115, and can only expand internally. The expanded oil absorption expansion sleeve 114 fills the gap, thereby contacting the two detection lines 112.

[0073] In the embodiment of the utility model, the limiting sleeve 115 can be made of nylon.

[0074] As a preferred embodiment of the present utility model, the outer wall of the center line 111 is provided with a plurality of spiral grooves for surrounding the isolation line 113 and the detection line 112 .

[0075] In the embodiment of the utility model, the spiral groove serves to prevent the isolation line 113 or the detection line 112 from sliding on the center line 111 .

[0076] As a preferred embodiment of the present utility model, the oil absorption expansion sleeve 114 is a sleeve structure, which expands after absorbing oil and contacts the two detection lines 112 .

[0077] In the embodiment of the present invention, the oil absorption expansion sleeve 114 can be made of a conductive material or a non-conductive material.

[0078] As a preferred embodiment of the utility model, the inner wall of the oil absorption expansion sleeve 114 is provided with a conductive layer, and the conductive layer contacts the two detection lines 112 after the oil absorption expansion sleeve 114 absorbs oil and expands, so that the two detection lines 112 contact to form a conductive loop.

[0079] In the embodiment of the utility model, since the inner wall of the oil absorption expansion sleeve 114 is provided with a conductive layer, after the oil absorption expansion, the two detection lines 112 are contacted at the expansion position to form a conductive loop. At this time, due to the existence of voltage, the current of the conductive loop flows, and the current flows from the input end of one detection line 112, flows through the conductive layer at the expansion position to the other detection line 112, and flows out from the input end of the detection line 112, so that the oil leakage controller 4 detects the current.

[0080] In the embodiment of the present utility model, Figure 2 As shown, P is the oil leakage point. The oil absorption expansion sleeve 114 of the oil leakage detection rope 11 in the first direction and the second direction absorbs oil and expands at P, and then contacts the two detection lines 112, so that the two detection lines 112 contact each other to form a conductive loop. Due to the existence of the limiting sleeve 115, the oil absorption expansion sleeves 114 of the two oil leakage detection ropes 11 will not contact each other, and the oil is not conductive, so the current on the oil leakage detection rope 11 in the first direction and the current on the oil leakage detection rope 11 in the second direction do not affect each other.

[0081] As a preferred embodiment of the present utility model, the limiting sleeve 115 is provided with a hole for oil to pass through.

[0082] In the embodiment of the utility model, the pores are provided to facilitate the penetration of oil materials and the expansion reaction of the oil absorption expansion sleeve 114.

[0083] like Figure 5 As shown, as a preferred embodiment of the present utility model, the connection module 2 includes two;

[0084] One of the connection modules 2 includes a connection wire 21 and a hollow pipe 22 for fixing the connection wire 21;

[0085] The input end of the connecting wire 21 is connected to the voltage output end of the oil leakage controller 4, and a plurality of output ends are provided, and the output ends are respectively connected to the input ends of a plurality of the oil leakage detection ropes 11. The connecting wire 21 is used to form a current loop between the oil leakage detection rope 11 that conducts current and the oil leakage controller 4 when oil leakage occurs, so that the oil leakage controller 4 detects the current;

[0086] A plurality of through holes 23 are provided on the side wall of the hollow pipe 22 for the oil leakage detection rope 11 to pass through.

[0087] In the embodiment of the present utility model, there are two connecting wires 21 , corresponding to the two detection lines 112 respectively.

[0088] In the embodiment of the utility model, the input end of the connecting wire 21 is the input end of the connecting module 2 , and the output end of the connecting wire 21 is the output end of the connecting module 2 .

[0089] In the embodiment of the utility model, the connecting wire 21 is a wire that can conduct current. The resistivity of the connecting wire 21 is very small, and the connecting wire 21 does not need to be set very long, so the resistance of the connecting wire 21 can be ignored.

[0090] In the embodiment of the utility model, the size of the through hole 23 formed on the side wall of the hollow pipe 22 is adapted to the cross-sectional size of the oil leakage detection rope 11 .

[0091] like Figure 6 As shown, as a preferred embodiment of the utility model, the fixing module 3 includes two;

[0092] One of the fixing modules 3 includes a fixing member 31 and a fixing buckle 32 fixed to the outer side of the fixing member 31;

[0093] There are a plurality of fixing buckles 32 , which are respectively fixed to the ends of a plurality of oil leakage detection ropes 11 .

[0094] In the embodiment of the present invention, the fixing member 31 may be the same as the hollow pipe 22 of the connecting module 2 .

[0095] In the embodiment of the utility model, the size of the buckle opening of the fixing buckle 32 is adapted to the cross-sectional size of the oil leakage detection rope 11 .

[0096] like Figure 7 As shown, as a preferred embodiment of the utility model, the oil leakage controller 4 includes a power supply module, a current detection module and a main control module;

[0097] The output end of the power module is connected to the input end of the connection module 2, and is used to provide voltage so that the oil leakage controller 4 detects current when oil leaks;

[0098] The detection end of the current detection module is connected to the output end of the power module, and the data sending end is connected to the data receiving end of the main control module, for detecting the current value and sending the detected current value to the main control module;

[0099] The main control module is used to determine the actual oil leakage position according to the current value and output it.

[0100] In this embodiment, the output end of the power module is the voltage output end of the oil leakage controller 4. The detection end of the current detection module can be connected to an interface of the output end of the power module. For example, the output end of the power module is a positive and negative pole, and the detection end of the current detection module is connected to the negative pole. The data sending end is used to send the current value, so the data receiving end of the main control module is used to receive the current value and process it. In essence, it is the principle of the MCU chip detecting the current value. This is a common technology and will not be described in detail here.

[0101] In this embodiment, the oil leakage controller 4 can be a device or a collection of multiple devices. If it is a collection of multiple devices, the oil leakage controller 4 also includes a communication module. For example, the current detection module, the power module and the communication module are integrated into a device A, and the device A is used to provide voltage and detect current value, and send the detected current value to the main control module through the communication module. The main control module can be a terminal. A main control module can be connected to multiple devices at the same time and serve as the main control module of multiple oil leakage controllers 4 at the same time. If the oil leakage controller 4 is a device, the power module also provides power for the current detection module and the main control module. If it is a collection of multiple devices, the power of the current detection module and the main control module can be provided by other power modules.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
