Description

Technical Field

[0001] The present invention relates to the technical field of liquid leakage detection, and in particular to a liquid leakage detection device, system and gene sequencer. Background Art

[0002] Liquid leakage detection usually exists in equipment with liquid pipelines or liquid storage tanks. It detects liquid leakage in liquid pipelines or liquid storage tanks to prevent leakage from affecting the equipment. For example, for gene sequencers, the liquid pipelines are an important and indispensable part of the instrument, and there are risks and problems of leakage caused by pipe collapse or blockage. Once the liquid pipeline leaks, the gene sequencer cannot sequence normally in the least, and the board on the gene sequencer will short-circuit and burn out in the worst case. Therefore, liquid pipeline leakage detection is very important.

[0003] So far, there are two main solutions for the leakage problem caused by the collapse or blockage of the liquid pipeline: the first method uses three parts, namely the first connecting piece, the second connecting piece and the electrode sheet. The main method is to connect the electrode sheet to the first connecting piece and the second connecting piece, and make the two connecting pieces at the same horizontal position. When liquid leaks out, the electrode sheet conducts electricity through the liquid, so that it can be used to detect whether there is a leakage; the second method is to use two leakage detection sensors to be installed directly on the bottom of the instrument. The resistance between the two leakage detection sensors will change according to whether there is liquid between the two leakage detection sensors, so it can be used to detect whether there is a leakage.

[0004] However, the current leak detection method is prone to misjudgment of leakage detection or even detection failure, so the leakage detection method needs to be improved. Summary of the invention

[0005] The main technical problem solved by the present invention is that leakage detection of liquid pipelines is prone to fail.

[0006] According to the first aspect, an embodiment provides a liquid leakage detection device, which is applied to liquid leakage detection of a liquid pipeline, and the liquid leakage detection device includes:

[0007] A leakage collection component, comprising a shell, the shell comprising a bottom, the bottom forming a collection space, the bottom of the shell having a to-be-detected area, the collection space being used to accommodate at least part of the liquid pipeline, so as to collect the leaked liquid to the to-be-detected area when leakage occurs in the liquid pipeline;

[0008] The ultrasonic detection component has a sensing surface, and the sensing surface is arranged toward the area to be detected; the ultrasonic detection component is used to detect liquid leakage in the area to be detected and obtain detection data; when the detection data is the first detection data, it is determined that the liquid pipeline is leaking.

[0009] According to the second aspect, an embodiment provides a liquid leakage detection system, comprising:

[0010] At least two liquid leakage detection devices as described in the first aspect, each of which is used to detect liquid leakage in liquid pipelines at different positions;

[0011] A communication unit, used for respectively communicating with the ultrasonic detection components of each of the liquid leakage detection devices;

[0012] Controller for:

[0013] Sending a control instruction through the communication unit to control any of the ultrasonic detection components to perform liquid leakage detection, and obtaining detection data of the controlled ultrasonic detection component;

[0014] When the detection data of the controlled ultrasonic detection component is the first detection data, determining that the liquid pipeline at the corresponding position has leakage;

[0015] The prompt unit is used to give a prompt message when it is determined that the liquid pipeline at the corresponding position has a leak.

[0016] According to the third aspect, an embodiment provides a gene sequencer, comprising:

[0017] at least one fluid line;

[0018] A sequencing system, used for gene sequencing of the target to be tested;

[0019] As in the liquid leakage detection device described in the first aspect or the liquid leakage detection system described in the second aspect, the liquid leakage detection device is used to detect liquid leakage on at least one of the liquid pipelines, and the liquid leakage detection system is used to detect liquid leakage on at least one of the liquid pipelines.

[0020] According to the leakage detection device of the above embodiment, the collection space of the leakage collection component can collect the leaked liquid when the liquid pipeline leaks, thereby preventing the leakage from directly affecting the equipment. At the same time, the collection space collects the leaked liquid to the area to be detected, and the ultrasonic detection component sensing surface faces the area to be detected to detect the leakage in the area to be detected. When the liquid pipeline leaks, regardless of whether it is a small area leak or a large area leak, the leak will be collected in the area to be detected and sensed by the ultrasonic detection component, thereby improving the detection effect of the detection component and avoiding easy failure of detection.

[0027] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0028] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0029] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0030] In the current scheme, whether it is the electrode sheet of the first type or the leakage detection sensor of the second type, they can only detect leakage at a specific location. For example, when the location where the leakage drops is not on the electrode sheet or between the two leakage detection sensors, the current scheme cannot detect the leakage, resulting in leakage detection failure when leakage occurs. Alternatively, when a large area of ​​leakage occurs, and the amount of leakage dripping on the electrode sheet or between the two leakage detection sensors is small, the current scheme may cause misjudgment of leakage detection.

[0031] At the same time, since the reagents used in the sequencer are usually corrosive, and the electrode sheet needs to be immersed in the leaked liquid, it is easy to be corroded after a long time, and the electrode sheet is easy to contact the metal part of the instrument when installed, resulting in short circuit misjudgment. In addition, the conductivity of the electrode sheet is related to the type of liquid. When the conductivity of the leaking liquid is not strong, the leak will not be detected correctly. Therefore, this detection method itself will also lead to misjudgment of the leak detection or even failure of the detection. The two leak detection sensors must be installed facing each other, otherwise it will lead to inaccurate detection, and the distance between the two is difficult to control. Therefore, this detection method itself will also lead to misjudgment of the leak detection or even failure of the detection. Even if the current solution can accurately detect the leak, the leak has already affected the equipment, for example, affecting the normal use of the gene sequencer or causing the board on the gene sequencer to short-circuit and burn out.

[0032] In some embodiments of the present invention, a leakage collection component is added, and the leakage collection component has a collection space and a detection area, wherein the collection space is used to accommodate at least part of the liquid pipeline, so that the leakage can be collected when the liquid pipeline leaks, thereby avoiding the leakage from directly affecting the equipment. At the same time, the collection space collects the leakage to the detection area, and the ultrasonic detection component senses the surface toward the detection area to detect the leakage. When the liquid pipeline leaks, regardless of whether it is a small area leakage or a large area leakage, the leakage will be collected in the detection area and sensed by the ultrasonic detection component, thereby improving the detection effect of the detection component and avoiding easy failure of the detection.

[0033] Some embodiments provide a liquid leakage detection device, which can be used for liquid leakage detection of liquid pipelines. The liquid leakage detection device is used to receive the liquid leakage generated by the liquid pipeline, collect the leaked liquid to the area to be detected, and then perform a liquid leakage detection on the area to be detected to determine whether the liquid pipeline is leaking. Please refer to Figure 1 The liquid leakage detection device includes a liquid leakage collection component 10, an ultrasonic detection component 20 and a liquid leakage alarm unit, which will be described in detail below.

[0034] The leakage collecting component 10 is used to receive and collect the leakage generated by the liquid pipeline 30. In some embodiments, the leakage collecting component 10 includes a shell, the shell includes a bottom 12, the bottom 12 of the shell forms a collection space 18, and the bottom 12 of the shell has a detection area 122.

[0035] In some embodiments, the collecting space 18 is used to accommodate at least part of the liquid pipeline 30. For example, in the horizontal direction, the collecting space 18 is larger than at least part of the liquid pipeline 30, so as to accommodate at least part of the liquid pipeline 30 in the horizontal direction. Therefore, when the liquid pipeline 30 leaks, the collecting space 18 can receive the leaked liquid generated by the liquid pipeline 30. In some embodiments, the collecting space 18 can be at a certain distance from the liquid pipeline 30, so that the leaked liquid of the liquid pipeline 30 drips into the collecting space 18. In some embodiments, the collecting space 18 can also be close to the liquid pipeline 30, so that the collecting space 18 can directly receive the leaked liquid generated by the liquid pipeline 30. In some embodiments, the collecting space 18 has an opening, in which case the liquid pipeline 30 can be located above the opening, or can be located on the opening and mounted on the bottom 12 of the shell. For example, a snap-in notch is provided on the top edge of the bottom 12, and the liquid pipeline 30 can be snapped or fixed to the snap-in notch, so that the portion of the liquid pipeline 30 mounted on the shell can also be accommodated by the collecting space 18 in the vertical direction, and the degree of accommodation is related to the depth of the snap-in notch. In this embodiment, the leakage collection component 10 can collect the leakage generated by the liquid pipeline 30, thereby preventing the leakage from directly affecting related equipment. Please refer to Figure 1 In some embodiments, in addition to the bottom 12, the shell also includes a top 16, and the top 16 is used to close the collection space 18, so that the collection space 18 becomes a sealed space. At this time, the liquid pipeline 30 can be set through the shell, so that the part of the liquid pipeline 30 that passes through the shell is completely contained in the collection space 18. In some embodiments, the connection formed by the shell being penetrated by the liquid pipeline 30 is sealed, for example, by a sealing ring or a sealant, so as to ensure better sealing. In this embodiment, the leakage collection component 10 can not only collect the leakage generated by the liquid pipeline 30, but also prevent the leakage from dripping or spraying to the outside of the leakage collection component 10, thereby further avoiding the leakage from affecting external equipment or instruments. In some embodiments, the shell can be made of corrosion-resistant material, so that corrosive leakage can be better contained.

[0036] It can be seen from the above embodiments that since the leakage collection component 10 can collect a certain amount of leakage generated by the liquid pipeline 30, the leakage will not affect the relevant equipment. At the same time, leakage generated at different places of the liquid pipeline 30 can be collected by the leakage collection component 10. For example, when the collection space 18 is open, any leakage generated at any place of the liquid pipeline 30 on the opening will be collected and may cause leakage in the area to be detected 122. For example, when the collection space 18 is sealed, any leakage or spray leakage generated at any place of the liquid pipeline 30 in the collection space 18 will also be collected and may cause leakage in the area to be detected 122.

[0037] In some embodiments, the collection space 18 is also used to collect the leaked liquid into the to-be-detected area 122 , so that when the leaked liquid is small, there can be leaked liquid in the to-be-detected area 122 .

[0038] Please refer to Figure 1 and Figure 2 In some embodiments, the bottom 12 of the shell further has an inclined guide area 124, and the guide area 124 is used to guide the collected leaked liquid to the area to be detected 122. In this embodiment, the guide area 124 is connected to the area to be detected 122 and is higher than the area to be detected 122 in the vertical direction. For example, the guide area 124 is an inclined surface or a curved surface, so that the guide area 124 can guide the collected leaked liquid to the area to be detected 122. In some embodiments, the bottom 12 of the shell includes a bottom edge 13, and a side edge 14 formed by extending the edge of the bottom edge 13, and a collection space 18 is formed between the bottom edge 13 and the side edge 14. In this embodiment, the guide area 124 and the area to be detected 122 are both located at the bottom edge 13 of the bottom 12, so that the leaked liquid can be collected in the area to be detected 122 at the bottom edge 13. In this embodiment, the side edge 14 can prevent the leaked liquid from splashing to the outside of the shell to a certain extent, and at the same time, it can also increase the space of the collection space 18 to collect more leaked liquid and prevent it from overflowing. Please refer to Figure 3 In some embodiments, the side edge 14 of the bottom 12 is inclined so that the collecting space 18 is gradually narrowed from top to bottom, and the above-mentioned detection area 122 is formed at the bottom edge 13 of the bottom 12, and the detection area 122 can be all or part of the bottom edge 13 of the bottom 12. Please refer to Figure 3 and 4 For example, the cross section of the collection space 18 in the vertical direction is trapezoidal, or the side 14 of the vertical cross section is an oblique line or a curve. The inclined side 14 can guide the collected leaked liquid to the bottom 13 of the bottom 12 of the shell, and the guide area 124 of the bottom 13 can guide the leaked liquid to the detection area 122. In this embodiment, after the side 14 of the bottom 12 is inclined, on the one hand, the leakage collection area of ​​the collection space 18 can be increased, and on the other hand, after collecting the leaked liquid, it can be collected to the bottom 13 of the bottom 12. Please refer to Figure 5In some embodiments, the area to be detected 122 is provided with a convergence area, and the convergence area is used to converge the leakage of the area to be detected 122. In this embodiment, since the size of the area to be detected 122 is associated with the ultrasonic detection component 20, when the area to be detected 122 is set to be small, even if there is less leakage in the area to be detected 122, the leakage will be concentrated in the area to be detected 122, which is conducive to the ultrasonic detection component 20 to accurately detect the leakage. On the contrary, when the area to be detected 122 is large, if there is less leakage in the area to be detected 122, the leakage will be dispersed in the area to be detected 122, thereby affecting the detection accuracy of the ultrasonic detection component 20. In this regard, a convergence area can be provided in the area to be detected 122, and the convergence area can converge the leakage of the area to be detected 122, so that even if there is less leakage in the area to be detected 122, the leakage can be concentrated in the convergence area, thereby improving the detection accuracy of the ultrasonic detection component 20. In some embodiments, the convergence area includes at least one convergence groove 126, which can be rectangular, elliptical or other strips, or square, circular or other shapes. The convergence groove 126 has a certain depth, so that the leakage of the area to be detected 122 can be better concentrated in the convergence groove 126, so as to facilitate the detection by the ultrasonic detection component 20. In some embodiments, the convergence groove 126 includes a bottom edge and a side edge, and the side edge is connected to other areas of the area to be detected 122. The bottom edge and other areas of the area to be detected 122 are usually horizontal, so as to facilitate the reflection of ultrasonic waves.

[0039] As can be seen from the above embodiments, the leakage collection component 10 can collect the leakage generated at various places of the liquid pipeline 30 and gather it to the to-be-detected area 122, so that when the leakage is small, the to-be-detected area 122 can also have leakage, thereby improving the leakage detection effect and avoiding the easy failure of leakage detection. At the same time, the leakage can be further gathered in the to-be-detected area 122, so that when there is less leakage in the to-be-detected area 122, there can be concentrated leakage in the convergence area of ​​the to-be-detected area 122, so as to further improve the leakage detection effect.

[0040] The ultrasonic detection component 20 has a sensing surface 22, which is disposed toward the area to be detected 122, for performing liquid leakage detection on the area to be detected 122 and obtaining detection data, which is used to determine whether the liquid pipeline 30 is leaking. In some embodiments, when there is liquid leakage in the area to be detected 122, the ultrasonic detection component 20 performs liquid leakage detection on the area to be detected 122 and obtains first detection data, which is used to determine whether there is liquid leakage in the liquid pipeline 30. Conversely, when there is no liquid leakage in the area to be detected 122, the ultrasonic detection component 20 performs liquid leakage detection on the area to be detected 122 and obtains second detection data, which is used to determine whether there is no liquid leakage in the liquid pipeline 30.

[0041] As can be seen from the above embodiments, the leakage collection component 10 can collect the leakage generated at various places of the liquid pipeline 30 through the collection space 18 and gather it to the to-be-detected area 122, and the ultrasonic detection component 20 only needs to perform leakage detection on the to-be-detected area 122 to determine whether there is leakage at various places of the liquid pipeline 30, thereby changing the leakage detection method from point detection of the leakage point of the liquid pipeline 30 to range detection of the leakage of the liquid pipeline 30. Therefore, the ultrasonic detection component 20 performs leakage detection on the to-be-detected area 122, which can greatly improve the leakage detection accuracy when the liquid pipeline 30 leaks, and on the other hand, can change the detection range of the liquid pipeline 30 from point detection to range detection, thereby greatly improving the leakage detection efficiency.

[0042] In some embodiments, the ultrasonic detection component 20 includes an ultrasonic sensor probe and an ultrasonic control circuit. The ultrasonic sensor probe includes a transducer composed of a plurality of array elements arranged in an array. The array element is used to transmit ultrasonic waves according to an excitation electrical signal, or to convert the received ultrasonic waves into electrical signals. Therefore, each array element can be used to realize the mutual conversion between electrical pulse signals and ultrasonic waves, thereby realizing the transmission of ultrasonic waves to the scanned object, and can also be used to receive the echo of the ultrasonic waves reflected back from the scanned object. The ultrasonic control circuit includes a transmitting circuit and a receiving circuit. The transmitting circuit is used to excite the ultrasonic sensor probe to transmit ultrasonic waves to the scanned object according to the acquired control signal, and the receiving circuit is used to receive the ultrasonic echo returned from the scanned object through the ultrasonic sensor probe to obtain an ultrasonic echo signal. In this embodiment, the ultrasonic sensor probe has a sensing surface 22, and the orientation of the sensing surface 22 is used to determine the direction in which the ultrasonic sensor probe transmits ultrasonic waves or receives ultrasonic echoes. Therefore, the sensing surface 22 needs to be arranged toward the area to be detected 122, for example, facing the area to be detected 122, so that the ultrasonic sensor probe is used to transmit ultrasonic waves to the area to be detected 122 and receive echoes of ultrasonic waves reflected by the area to be detected 122. In this embodiment, the sensing surface 22 of the ultrasonic sensor probe can match the area to be detected 122, for example, the sensing surface 22 is opposite to the area to be detected 122, and the two are parallel, so as to facilitate the reception of ultrasonic echoes. For example, the area of ​​the area to be detected 122 is at least not less than the area of ​​the sensing surface 22, which can better reflect all ultrasonic waves on the one hand, and on the other hand, when there is leakage in the area to be detected 122, the sensing surface 22 can detect the leakage. In this embodiment, when the sensing surface 22 of the ultrasonic sensor probe faces downward and is facing the area to be detected 122, even if only a small amount of liquid leakage occurs in the liquid pipeline 30, the sensing surface 22 of the ultrasonic sensor probe can detect the liquid leakage in the area to be detected 122. Otherwise, if the sensing surface 22 of the ultrasonic sensor probe faces upward and is facing the liquid pipeline 30, the leakage can only be detected when the leakage liquid submerges the sensing surface 22 or the leakage liquid just drips on the sensing surface 22. Therefore, the ultrasonic detection component 20 does not need to be in contact with the leakage liquid, and the installation position requirement is not so strict, thereby ensuring a better detection effect.

[0043] In some embodiments, the ultrasonic detection component 20 receives the echo of the ultrasonic wave reflected by the detection area 122, and converts it into an electrical signal, that is, an ultrasonic echo signal, and the ultrasonic echo signal can be used to determine the detection data obtained by the ultrasonic detection component 20. In this embodiment, when there is no leakage in the detection area 122, the echo intensity of the ultrasonic wave reflected by the detection area 122 is weak, so the ultrasonic echo signal is small, on the contrary, when there is leakage in the detection area 122, the echo intensity of the ultrasonic wave reflected by the detection area 122 is strong, so the ultrasonic echo signal is large, so a detection threshold can be set, when the ultrasonic echo signal is greater than the threshold, it can be judged that there is leakage in the detection area 122, and it can be judged that the liquid line pipeline 30 has leakage, on the contrary, it is judged that there is no leakage in the liquid line pipeline 30.

[0044] In some embodiments, the ultrasonic sensor probe and the liquid pipeline 30 are staggered in the horizontal direction. In this embodiment, when the ultrasonic sensor probe and the liquid pipeline 30 are staggered, it can be prevented that the leakage of the liquid pipeline 30 directly drips onto the ultrasonic sensor probe, thereby failing to detect the leakage of the liquid pipeline 30 in the first time. In some embodiments, in order to detect the leakage dripping from the top of the ultrasonic sensor probe, a drainage sheet can be provided above the ultrasonic sensor probe, and the drainage sheet can drain the leakage dripping from the top of the ultrasonic sensor probe to the bottom of the ultrasonic sensor probe, for example, directly to the area to be detected 122.

[0045] In some embodiments, the ultrasonic sensor probe is installed by a fixing bracket 24, and the fixing bracket 24 is fixed to the bottom 12 or the top 16 of the shell. After the ultrasonic sensor probe is installed on the fixing bracket 24, the sensing surface 22 of the ultrasonic sensor probe faces the area to be detected 122, and is separated from the area to be detected 122 by a certain distance, and the distance can be adjusted according to the actual detection situation. In this embodiment, since the sealing of the shell is required to be good, the fixing bracket 24 cannot be fixed by screws, for example, it can be fixed by gluing. In this embodiment, the fixing bracket 24 can be used as a drainage plate, and the drainage plate can also be set above the fixing bracket 24. In some embodiments, the ultrasonic detection component 20 also includes a lead wire 26, which includes a power line and a signal line of the ultrasonic detection component 20. The power line is used to power the ultrasonic detection component 20, for example, the power supply range is 5V-12V, and the signal line is used to transmit data, for example, the high level is 5V, and the low level is 0V. The length of the lead wire will have an attenuation effect on the detection signal, so the cable must use the sensor's own line, and the cable length must not exceed 3 meters. At the same time, the lead wire can be led out from the top 16 or bottom 12 of the shell, and sealed at the connection with the shell.

[0046] In some embodiments, when there are multiple liquid pipelines 30, for example, multiple liquid pipelines 30 are arranged side by side and adjacent to each other, the collection space 18 can be used to accommodate at least part of at least two liquid pipelines 30, so that when any of the liquid pipelines 30 leaks, the leaked liquid can be collected and collected in the to-be-detected area 122. In this embodiment, the leaked liquid collection component 10 can collect the leaked liquid of multiple liquid pipelines 30, so that only one ultrasonic detection component can be used for leak detection for multiple liquid pipelines 30, so as to reduce the cost of leak detection.

[0047] In some embodiments, the liquid pipeline 30 includes at least a first section of the pipe 32 and a second section of the pipe 34, and the first section of the pipe 32 and the second section of the pipe 34 are sealed and connected to form a sealing section 36. In this embodiment, the liquid pipeline 30 is obtained by sealingly connecting at least the first section of the pipe 32 and the second section of the pipe 34. For example, when the length of the first section of the pipe 32 is not enough or a turning setting is required, the second section of the pipe 34 needs to be sealed and connected, and the first section of the pipe 32 and the second section of the pipe 34 are both used for liquid to flow through. Since the first section of the pipe 32 and the second section of the pipe 34 need to be sealed and connected to form a sealing section 36, and the sealing section 36 is most likely to leak, the collection space 18 of the leakage collection component 10 is used to accommodate at least part of the sealing section 36, for example, the sealing section 36 is entirely or partially mounted on the shell, for example, one end of the sealing section 36 or the entirety is accommodated in the sealed collection space 18, so as to effectively detect the leakage of the liquid pipeline 30. In some embodiments, the first pipe section 32 and the second pipe section 34 are sealed and connected by a liquid pipe threaded joint, and the liquid pipe threaded joint is used to connect the independent first pipe section 32 and the second pipe section 34 by threaded engagement, and the liquid pipe threaded joint is connected to each pipe section by a liquid pipe joint and two liquid pipe fixed joints, wherein the liquid pipe joint is used to connect the liquid pipe threaded joint to each pipe section, and the liquid pipe fixed joint is used to prevent the connection between the liquid pipe threaded joint and each pipe section from loosening, and its function is similar to that of a rubber ring.

[0048] The liquid leakage alarm unit is used to give an alarm when it is determined that a liquid pipeline has a leak. In some embodiments, the liquid leakage alarm unit can give an alarm in the form of sound and light. For example, the liquid leakage alarm unit can give an audible alarm or a voice alarm through a sound playing device such as a speaker. For example, the liquid leakage alarm unit can give an illuminating alarm through a luminous device such as an alarm lamp. For example, the liquid leakage alarm unit can display the alarm information through a display device such as a display screen.

[0049] It can be seen from the above embodiments that the leakage detection device is added with a leakage collection component 10, and the leakage collection component 10 can collect large-area leakage of the liquid pipeline 30, thereby preventing the leakage from affecting external equipment. The leakage collection component 10 can also gather the collected leakage in the detection area 122, and detect the leakage through the sensing surface 22 of the ultrasonic detection component 20 toward the detection area 122, so that even a small leakage of the liquid pipeline 30 can be detected, thereby improving the detection effect. At the same time, the leakage detection method of the ultrasonic detection component 20 is changed from leakage point detection to leakage range detection, which greatly increases the leakage detection area of ​​the liquid pipeline 30, and can also be used for leakage detection of multiple liquid pipelines 30 at the same time, improving the leakage detection efficiency, and further improving the detection effect, and avoiding easy failure of detection.

[0050] The above is some description of the liquid leakage detection device. The following is a specific description of the liquid leakage detection system composed of multiple liquid leakage detection devices.

[0051] In some embodiments, a liquid leakage detection system is provided, which is used to simultaneously detect liquid leakage in a liquid pipeline 30 at multiple locations, and when a liquid pipeline 30 at any location leaks, the liquid leakage detection system can also determine the specific location of the liquid pipeline 30 at any location. Figure 2 The liquid leakage detection system includes at least two liquid leakage detection devices, a communication unit 40, a prompt unit 50 and a controller 60, which are described in detail below.

[0052] The leakage detection device can be the leakage detection device in the above embodiment, wherein each leakage detection device is used to detect leakage of the liquid pipeline 30 at different positions and obtain detection data. There can be one or more liquid pipelines 30 at each position.

[0053] The communication unit 40 is used to communicate with the ultrasonic detection components in each leakage detection device, so that each ultrasonic detection component can be controlled to perform leakage detection and obtain the detection data obtained. In some embodiments, the communication unit 40 can be a wired communication module, such as a 485 communication module, a 232 communication module, etc. The communication unit 40 can also be a wireless communication module, such as a Bluetooth module, a ZigBee module, etc. It can be understood that the communication unit 40 can be used as long as it can be used for data transmission. In some embodiments, the communication unit 40 can also be used to communicate with other external devices, such as a host computer, a service terminal, a user terminal, etc.

[0054] The prompt unit 50 is used to give prompt information. In some embodiments, the prompt unit 50 may adopt a human-computer interaction device, which may include a display and an input device. Among them, the input device is used to receive input from a user (usually an operator), for example, one or more of a mouse, a keyboard, a touch display, a trackball, and a joystick may be used to receive instructions input by the user. The user can perform input operations through the input device. The display is used to output information, such as outputting visual information such as prompt information. The display may adopt a display with only a display function, or a touch display. In some embodiments, the prompt unit 50 may also be just a display unit to display prompt information. In some embodiments, the prompt unit 50 may also be a voice module, which may give prompt information by outputting voice. In some embodiments, the prompt unit 50 may also be a plurality of indicator lights, for example, different indicator lights indicate different prompt information.

[0055] The controller 60 is used to send a control instruction through the communication unit 40 to control any ultrasonic detection component to perform leakage detection, and obtain the detection data of any ultrasonic detection component. In some embodiments, the controller 60 is used to control any ultrasonic detection component to perform at least one leakage detection, and obtain at least one detection data. In this embodiment, by performing leakage detection multiple times, accidental errors in detection can be avoided, thereby improving the judgment of leakage detection of the liquid pipeline 30, and thus having high accuracy. In this embodiment, the controller 60 can send a control instruction to control the corresponding ultrasonic detection component to perform leakage detection after obtaining the instruction input by the user, or it can perform detection according to a pre-set detection strategy, such as performing a round of detection at intervals, and performing at least one leakage detection in each round of detection.

[0056] The controller 60 is also used to determine whether the liquid pipeline 30 at the corresponding position is leaking according to the detection data of any ultrasonic detection component, and obtain the detection result. In some embodiments, when only one leakage detection is performed, the controller 60 is used to determine whether the detection data meets the preset conditions. For example, the detection data is usually a value indicating the detection intensity. If the value is greater than the threshold, the liquid pipeline 30 at the corresponding position is judged to be leaking, otherwise it is judged that the liquid pipeline 30 at the corresponding position is not leaking, and it is used as the detection result. In some embodiments, when multiple leakage detections are performed within a shorter preset time, such as within 1 second or 2 seconds, the controller 60 then determines whether the detection data of each time meets the preset conditions, and also determines whether the number of detection data that meets the preset conditions reaches the preset number, or reaches the preset proportion of the total number, such as reaching more than half of the proportion, or reaching the preset number under a certain number of times. If the preset number is reached, or the preset proportion is reached, the liquid pipeline 30 at the corresponding position is judged to be leaking, otherwise it is judged that the liquid pipeline 30 at the corresponding position is not leaking, and it is used as the detection result.

[0057] The controller 60 also obtains the position information of any ultrasonic detection component through the communication unit 40, and the position information is also the position information of the leaking pipeline at the corresponding position of the ultrasonic detection component, and controls the prompt unit 50 to give prompt information of at least one of the position information, detection data and detection result of any ultrasonic detection component. For example, each ultrasonic detection component can be numbered, and the number of the ultrasonic detection component corresponds to the liquid pipeline 30 at its location. Therefore, when the controller 60 obtains the number of the ultrasonic detection component, its position information can be obtained. When the controller 60 obtains the detection result of any ultrasonic detection component, the position information, detection result and detection data of the ultrasonic detection component are given prompt information through the prompt unit 50. The user can immediately obtain the leakage of the liquid pipeline 30 at a specific location based on the prompt information of the position information, detection data and detection result, so that the leakage and position of the liquid pipeline 30 can be obtained at the first time when the leakage occurs, so as to reduce the maintenance time of the liquid pipeline 30.

[0058] The following is a detailed description of the liquid leakage detection process performed by the ultrasonic detection component 20.

[0059] When the controller 60 controls the ultrasonic detection component 20 No. 1 to detect the liquid leakage of the liquid pipeline 30 at position 1, the controller 60 controls the ultrasonic detection component 20 No. 1 to continuously transmit ultrasonic waves to the detection area 122 for ten times, and continuously receive the echo of the ultrasonic waves reflected by the detection area 122 ten times, so as to obtain ten ultrasonic echo signals. The controller 60 obtains ten ultrasonic echo signals and compares them with the preset threshold value respectively. If the ultrasonic echo signal is greater than the preset threshold value, it is recorded, and finally the number of times the ultrasonic echo signal is greater than the preset threshold value is obtained. If the number is greater than five times, it is judged that the ultrasonic detection component 20 No. 1 detects the liquid leakage, and prompts the ultrasonic detection component 20 No. 1 to detect the liquid pipeline 30 at position 1. Otherwise, it prompts the ultrasonic detection component 20 No. 1 to detect that the liquid pipeline 30 at position 1 does not leak. Similarly, the detection results of other ultrasonic detection components 20 can be judged, and the detection results and position information of other ultrasonic detection components 20 can be prompted. Therefore, the user does not need to disassemble the device and can intuitively check the actual conditions of each liquid pipeline 30 in the device.

[0060] In some embodiments, a gene sequencer is provided for performing gene sequencing on a target to be tested, such as DNA and RNA. The gene sequencer includes at least one liquid pipeline 30, a sequencing system and a liquid leakage detection device, or includes at least one liquid pipeline 30, a sequencing system and a liquid leakage detection system, which are described in detail below.

[0061] The at least one liquid pipeline 30 may be one liquid pipeline 30 or multiple liquid pipelines 30 located at one position, or one liquid pipeline 30 or multiple liquid pipelines 30 located at multiple positions. The liquid pipeline 30 may be used to transport reagents used by the sequencing system for sequencing.

[0062] The sequencing system is used to perform gene sequencing on the target to be tested.

[0063] The liquid leakage detection device may adopt the liquid leakage detection device in the above embodiment, which can be used for liquid leakage detection of at least one liquid pipeline 30 at one location.

[0064] The liquid leakage detection system may adopt the liquid leakage detection system in the above embodiment, which may be used for at least one liquid pipeline 30 at different positions to perform liquid leakage detection.

[0065] In this embodiment, when the liquid pipeline 30 in the gene sequencer collapses or is blocked, resulting in leakage, the leakage detection device or the leakage detection system can be used to ensure that the operator can promptly and accurately determine whether there is leakage, and can accurately determine the specific location of the leaking liquid pipeline 30, so as to avoid sequencing failure or short circuit and burnout of the board on the instrument. The leakage detection system can increase or decrease the number of leakage detection devices according to the needs of the liquid pipeline 30, so as to ensure that a leakage detection device is installed at a location where there is a liquid pipeline 30.
