DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0027] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0028] At present, in complex industrial environments such as mine exploitation, real-time parameter (such as pressure, temperature, viscosity, pollution degree) detection of liquid medium (such as hydraulic oil, cooling liquid) in key equipment such as hydraulic system, cooling system or lubricating system is an important technical means to judge the running health status of the equipment and prevent sudden failure.

[0029] In related technologies, the liquid parameter detection system usually adopts an external or internal pipeline network to guide the liquid to be detected from the main loop of the equipment to the inside of a centralized sensor container or detection box. In the box, a large number of joints and tees are needed for connection. In actual application, a large number of mechanical connection points become potential weak links of liquid leakage. Under the harsh working conditions of continuous vibration, temperature change and pressure impact in the mine, the pipeline joints are prone to looseness, aging or sealing failure, thereby causing liquid leakage. Once leakage occurs, the electrically conductive liquid directly sprays onto the electrical elements in the box, which is extremely easy to cause short circuit and even electrical fire. This not only easily leads to high failure rate of the detection system itself, but also may cause the key mining equipment (such as coal mining machine, hydraulic support) to be shut down due to false alarm or signal interruption, which seriously affects the production efficiency and operation safety of the mine.

[0030] In view of this, in order to reduce the failure rate and reduce downtime, the embodiment of the present application provides a liquid medium detection device, which comprises a box body, a partition plate, a control unit, a detection cavity and a detection unit. Wherein, the box body is provided with a containing cavity, a liquid inlet channel and a liquid outlet channel. The partition plate is arranged in the containing cavity and divides the containing cavity into an electrical cavity and a liquid cavity. The control unit is arranged in the electrical cavity. The detection cavity is arranged in the box body, and the detection container is provided with a detection port, a liquid inlet and a liquid outlet; the detection port and the liquid cavity are communicated, the liquid inlet is connected with one end of the liquid inlet channel, and the liquid outlet is connected with one end of the liquid outlet channel. The detection unit is arranged in the detection port and is electrically connected with the control unit. In this way, the liquid to be detected can enter the detection cavity through the liquid inlet channel and finally flow out from the liquid outlet channel. In this process, the detection unit measures the liquid flowing through the detection cavity through the detection port and transmits the signal to the control unit located in the electrical cavity. The liquid medium detection device physically separates the electrical cavity and the liquid cavity through the partition plate, so as to prevent the liquid from leaking into the electrical cavity; at the same time, the liquid inlet channel and the liquid outlet channel are arranged on the box body, the connecting pipeline is cancelled, only the detection port of the detection cavity and the liquid cavity are communicated, which serves as the installation position of the detection unit, so that the liquid leakage point is only the detection port, thereby effectively reducing the leakage points in the box body, and further reducing the risk of liquid leakage.

[0031] It can be understood that the liquid medium detection device provided by the embodiment of the present application can be used to detect the physical parameters and / or chemical parameters of the liquid medium, including but not limited to temperature, pressure, flow rate, viscosity, density, dielectric constant, pollution degree, water content or component concentration. The liquid medium includes but is not limited to water, hydraulic oil, emulsion and other working media.

[0032] The liquid medium detection device provided by the embodiment of the present application can be used in a detection system as part of the detection system, or in various working equipment that needs to detect liquid medium as part of the state monitoring system of the working equipment. The working equipment includes but is not limited to mining equipment and engineering machinery and the like. Among them, the mining equipment can include coal mining machine, heading machine and hydraulic support and the like; the engineering machinery can include excavator, loader and shield machine and the like.

[0033] The liquid medium detection device, system and working equipment provided by the embodiment of the present application will be described in detail in combination with Figures 1 to 3 specific embodiments and application scenarios.

[0034] Referring to Figure 1 and Figure 2 , the present application provides a liquid medium detection device, the structure of which comprises a box body 100, a partition plate 110, a control unit 200, a detection cavity 120 and a detection unit 300.

[0035] The box 100 is provided with a containing cavity 130, a liquid inlet channel 140 and a liquid outlet channel 150. The baffle 110 is arranged in the containing cavity 130 and divides the containing cavity 130 into an electrical cavity 132 and a liquid cavity 134. The control unit 200 is arranged in the electrical cavity 132. The detection containing cavity 120 is arranged on the side wall of the liquid cavity 134 and is provided with a detection port 122, a liquid inlet port 124 and a liquid outlet port 126. The detection port 122 and the liquid cavity 134 are communicated, the liquid inlet port 124 is connected with one end of the liquid inlet channel 140, and the liquid outlet port 126 is connected with one end of the liquid outlet channel 150. The detection unit 300 is arranged in the detection port 122 and is electrically connected with the control unit 200.

[0036] Specifically, the box 100 is an external support structure of the whole device, which is used to provide installation and accommodation space for internal components, so as to protect the internal components from external environment interference and ensure that the whole detection process is carried out in a relatively stable environment. The containing cavity 130 is used to accommodate other components. The liquid inlet channel 140 and the liquid outlet channel 150 provide a flow channel for the liquid medium to enter and exit the detection device, so as to guide the liquid medium to enter and exit the liquid medium detection device. It can be understood that the box 100 can be an explosion-proof box, so as to improve the safety of the liquid medium detection device in the downhole environment.

[0037] The baffle 110 is arranged in the containing cavity 130 and divides the containing cavity 130 into the electrical cavity 132 and the liquid cavity 134. In this way, the electrical elements which do not need to contact with the liquid medium can be arranged in the electrical cavity 132, and the related components which need to contact with the liquid medium can be arranged in the liquid cavity 134. Thus, the liquid leakage to the electrical cavity 132 can be effectively prevented, the damage of the electrical elements caused by the liquid medium can be avoided, and the reliability and safety of the whole liquid medium detection device can be improved, and the downtime can be reduced.

[0038] The control unit 200 has data processing capability, can receive the signal transmitted by the detection unit 300, and can analyze and process the signal, so as to obtain the related parameter information of the liquid medium and judge whether the state and parameters of the liquid medium meet the requirements. It can be understood that the control unit 200 does not need to contact with the liquid, and is arranged in the electrical cavity 132, so as to provide a liquid-free working environment for the control unit 200, so as to ensure that the control unit 200 can stably operate. At the same time, arranging the control unit 200 in the electrical cavity 132 is convenient for maintenance and management, and can effectively reduce the maintenance cost and difficulty.

[0039] The detection cavity 120 is used to store the liquid medium, and is a space in which the liquid medium is detected in the liquid medium detection device. The liquid medium enters the detection cavity 120 through the liquid inlet 124 and then flows out from the liquid outlet 126. During the flow process, the detection unit 300 measures the liquid medium through the detection port 122. The detection cavity 120 is only connected to the liquid cavity 134 through the detection port 122 and the installation position of the detection unit 300, so that the only liquid leakage point is the detection port 122, thereby effectively reducing the leakage points inside the box 100, and further reducing the risk of liquid medium leakage.

[0040] The detection unit 300 is arranged at the detection port 122 and is used to measure the parameters of the liquid medium in the detection cavity 120. It can be understood that the detection unit 300 includes various types of sensors, such as temperature sensors, pressure sensors, flow rate sensors, etc., to measure different parameters of the liquid medium.

[0041] In actual application, the liquid medium enters the detection cavity 120 through the liquid inlet channel 140 and flows out through the liquid outlet channel 150. During the flow process, the detection unit 300 measures the parameters of the liquid medium and transmits signals to the control unit 200 located in the electrical cavity 132.

[0042] In the above embodiment, the electrical cavity 132 and the liquid cavity 134 are physically isolated by the partition plate 110, so that liquid leakage into the electrical cavity 132 can be prevented; at the same time, the connecting pipeline is cancelled, and the detection cavity 120 is directly connected to the liquid inlet channel 140 and the liquid outlet channel 150 on the box 100, and only the detection port 122 of the detection cavity 120 is connected to the liquid cavity 134 as the installation position of the detection unit 300, so that the only liquid leakage point is the detection port 122, thereby effectively reducing the leakage points inside the box 100, and further reducing the risk of liquid leakage. In this way, the reliability and safety of the liquid medium detection device can be effectively improved, thereby reducing downtime.

[0043] In some embodiments, the liquid medium detection device further comprises a liquid leakage detection unit 400. The liquid leakage detection unit 400 is arranged in the liquid cavity 134 and is used to monitor whether there is liquid in the liquid cavity 134.

[0044] The detection port 122 can cause liquid medium to leak into the liquid cavity 134 due to various unpredictable factors such as aging, collision, extreme working conditions, and the like. If the leakage is long-term, on the one hand, it can cause the detection result to deviate, and the real state of the liquid medium cannot be accurately reflected. On the other hand, although the baffle 110 separates the electrical cavity 132 and the liquid cavity 134, if the amount of leakage is too large or the sealing performance of the baffle 110 decreases due to long-term use, the liquid medium can seep into the electrical cavity 132 and contact the electrical element, thereby causing a short circuit fault of the electrical element, and further affecting the stability and reliability of the entire liquid medium detection device.

[0045] Therefore, in the above embodiment, by arranging the liquid leakage detection unit 400, the leakage of the liquid medium can be monitored in real time, so that the leakage can be detected in time and a leakage signal can be sent to shut off the liquid inlet channel 140 or stop the operation of the related equipment, thereby avoiding continuous leakage of the liquid medium.

[0046] It can be understood that the liquid leakage detection unit 400 can use the principles of electrical conductivity (judging the presence of liquid by detecting the change of electrical conductivity between electrodes), optical type (detecting the liquid level by the change of refraction or transmittance of infrared light), float type (using the float to trigger a switch by rising and falling with the liquid level), and the like to detect the liquid leakage.

[0047] In some embodiments, the liquid leakage detection unit 400 is arranged at the bottom of the liquid cavity 134. Since the liquid medium leaks and gathers at the bottom, the liquid leakage detection unit 400 is arranged at the bottom (i.e., the low position) of the liquid cavity 134. In this way, once leakage occurs, the liquid medium can quickly flow to the detection area of the liquid leakage detection unit 400, so that the liquid leakage detection unit 400 can timely find the leakage of the detection port 122.

[0048] In some embodiments, the position of the liquid outlet 126 is higher than that of the liquid inlet 124 along the direction of gravity.

[0049] Under natural conditions, the liquid medium has a downward flow tendency under the action of gravity. By arranging the position of the liquid outlet 126 of the detection cavity 120 to be higher than that of the liquid inlet 124, the liquid medium cannot flow out of the liquid outlet 126 at the beginning after entering the detection cavity 120 from the liquid inlet 124, and can be discharged only after the liquid level of the detection cavity 120 reaches a certain height due to the continuous increase of the liquid inlet amount. In this way, it can be ensured that the detection cavity 120 always stores liquid medium, and emptying can be avoided. Therefore, when detecting, the detection position of the detection unit 300 can be arranged below the position of the liquid outlet 126, so that the detection unit 300 can always be in contact with the liquid medium, thereby ensuring that the detection data of the detection unit 300 is always valid.

[0050] In some embodiments, the liquid medium detection device further comprises a first connector 510 and a first breathing liquid discharge unit 520. The first connector 510 is connected to the other end of the liquid inlet channel 140 and at least partially located outside the box 100. The first breathing liquid discharge unit 520 is arranged at the first connector 510.

[0051] Specifically, the first connector 510 serves as a quick connection interface for connecting the external liquid medium source and the liquid inlet channel 140. By arranging the first connector 510, the liquid medium detection device can quickly and stably access the liquid medium source, so that the liquid medium flows into the detection device.

[0052] The first breathing liquid discharge unit 520 has a breathing function. When the detection cavity 120 is filled with liquid, the air in the detection cavity 120 and the liquid inlet channel 140 needs to be discharged to avoid air blockage. When the liquid is discharged, external air needs to enter to avoid vacuum formation. In this way, the pressure balance in the device is maintained, and the smooth flow of the liquid medium is ensured. At the same time, the first breathing liquid discharge unit 520 also has a liquid discharge function. In actual application, the detection device sometimes needs to discharge the liquid medium. For example, when there is too much liquid medium, the first breathing liquid discharge unit can provide an emergency liquid discharge channel to ensure the normal operation of the detection device.

[0053] In some embodiments, the liquid medium detection device further comprises a second connector 610 and a second breathing liquid discharge unit 620. The second connector 610 is connected to the other end of the liquid outlet channel 150 and at least partially located outside the box 100. The second breathing liquid discharge unit 620 is arranged at the second connector 610.

[0054] The second connector 610 serves as a quick connection interface for connecting the liquid outlet channel 150 and the liquid medium source. In this way, the liquid medium detection device can quickly and stably access the liquid medium source, so that the liquid medium flows back to the liquid medium source.

[0055] The second breathing liquid discharge unit 620 and the first breathing liquid discharge unit 520 have similar structures and also have breathing and liquid discharge functions.

[0056] In the above embodiments, the first connector 510 and the first breathing liquid discharge unit 520 are responsible for the access of the liquid medium and the regulation of the inlet end pressure, and the second connector 610 and the second breathing liquid discharge unit 620 are responsible for the discharge of the liquid medium and the regulation of the end pressure. The two cooperate to maintain the stable pressure inside the detection device, so as to ensure the normal operation of the detection device.

[0057] In actual application, the breathing liquid discharge unit has a protection function in addition to the functions of air discharge and liquid passage, so as to effectively prevent the release of explosive gas to the outside.

[0058] ReferenceFigure 1 and Figure 2 In some embodiments, the box 100 comprises a shell 160 and a fixing base 170. The shell 160 is provided with an opening 162, and the fixing base 170 is arranged on the opening 162 to form the accommodating cavity 130 together with the shell 160. The detection cavity 120, the liquid inlet channel 140 and the liquid outlet channel 150 are integrally arranged in the fixing base 170.

[0059] Specifically, the shell 160 serves as the main structure of the box 100 and is provided with the opening 162. The fixing base 170 is tightly connected with the shell 160 by means of bolts, buckles or welding, etc. to form a closed space of the accommodating cavity 130. The detection cavity 120, the liquid inlet channel 140 and the liquid outlet channel 150 are all integrated in the fixing base 170. In this way, only the detection port 122 of the detection cavity 120 and the liquid cavity 134 are in communication, serving as the installation position of the detection unit 300. The liquid inlet channel 140 and the liquid outlet channel 150 are all located inside the fixing base 170 and are isolated from the liquid cavity 134. Thus, the only leakage point of the liquid is the detection port 122, thereby effectively reducing the leakage points inside the box 100 and further reducing the risk of liquid leakage. In this way, the reliability and safety of the liquid medium detection device can be effectively improved, thereby reducing downtime. Meanwhile, by integrating the flow channel with the fixing base, it can be produced and replaced as a standard unit, simplifying assembly and facilitating maintenance.

[0060] In actual application, the fixing base 170 is arranged at the bottom of the box 100, and the partition plate 110 divides the accommodating cavity 130 into the electric cavity 132 and the liquid cavity 134 distributed in upper and lower positions. The liquid inlet channel 140 and the liquid outlet channel 150 are arranged at opposite sides of the detection cavity 120, respectively.

[0061] In some embodiments, the liquid medium detection device further comprises a wiring terminal 112 arranged on the partition plate 110.

[0062] Specifically, the wiring terminal 112 is used to connect the detection unit 300 and the control unit 200. The electric wire in the detection unit 300 is connected with the wiring terminal 112 and is led out by the wiring terminal 112 to be connected with the control unit 200 in the electric cavity 132 through the liquid cavity 134.

[0063] It can be understood that the wiring terminal 112 has an explosion-proof certification and meets the requirements for use in the well. In this way, the reliability of the isolation between the electric cavity 132 and the liquid cavity 134 can be further improved.

[0064] In some embodiments, the liquid medium detection device further comprises an incoming line connector 710 and an outgoing line connector 720. The incoming line connector 710 and the outgoing line connector 720 are both arranged on the side wall of the electrical cavity 132. The host computer is electrically connected to the incoming line connector 710 and the outgoing line connector 720 to connect the control unit 200. In this way, the liquid medium parameters detected by the detection unit 300 can be uploaded to the host computer in real time after being processed by the control unit 200, so that remote monitoring can be realized.

[0065] The incoming line connector 710 and the outgoing line connector 720 provide a standardized interface, and the operator only needs to connect the cable to the connector, which is simple to operate. When replacement or maintenance is needed, the cable connection can be easily disconnected without the need for rewiring.

[0066] In practical applications, the incoming line connector 710 and the outgoing line connector 720 are arranged on opposite sides of the electrical cavity 132.

[0067] Reference Figure 3 It can be understood that the control unit 200 also has bus and wireless communication functions. Specifically, the control unit has a communication interface 204. In this way, the optimal communication mode can be selected according to the site conditions, the wiring is simplified, the deployment cost is reduced, and the flexibility of the detection device is greatly enhanced.

[0068] In some embodiments, the control unit 200 further comprises a display unit 205, so that the liquid medium parameters can be displayed in real time to facilitate the operator to view on site.

[0069] In practical applications, the control unit further comprises a keyboard processing unit 206 and a power module 207. In this way, the power module 207 can supply power, and the operator can perform on-site operation.

[0070] The following will be described in conjunction with Figure 3 The detection process of the liquid medium detection device provided by the embodiments of the present application will be described in detail.

[0071] The control unit 200 is provided with a signal processing unit B 202, a signal processing unit A 203, a communication interface 204, a display unit 205 and a signal acquisition unit 208. The signal acquisition unit 208 acquires the signals of the detection unit 300 and the liquid leakage detection unit 400, which are processed by the control unit 200. On the one hand, the signals are sent to the host computer through the communication interface 204 by the signal processing unit A 203, and on the other hand, the signals are sent to the actuator to perform corresponding actions by the signal processing unit B 202.
