Description

Technical Field

[0001] The utility model relates to the technical field of liquid storage monitoring equipment, in particular to a video monitoring device with the function of liquid leakage identification. Background Art

[0002] In the production process, liquid materials are usually stored in liquid tanks. There is usually a liquid outlet at the bottom of the liquid tank, through which the materials are loaded onto trucks or transported to other places. However, liquid leakage often occurs in the liquid inlet, liquid outlet and other leakage areas, which will cause certain waste. If the liquid material is toxic or volatile, continuous leakage is likely to cause safety accidents and directly cause environmental pollution. Therefore, in order to prevent leakage caused by damage to the liquid tank, it is necessary to monitor the liquid tank for leakage.

[0003] Generally, traditional leakage identification technology is to monitor by naked eyes through manual patrol. However, manual patrol is not only time-consuming, labor-intensive, and has low monitoring efficiency, but also involves certain personnel risks. Therefore, how to replace manual labor to monitor whether a liquid storage tank is leaking in real time is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0004] The purpose of the utility model is to provide a video monitoring device with leakage recognition function to solve the above-mentioned problems, so as to replace manual patrol detection and reduce labor costs. When a liquid storage bottle leaks, the leakage can be detected in time and an alarm can be issued, thereby improving monitoring efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0006] A video monitoring device with liquid leakage identification includes a monitoring device capable of remote video monitoring, and also includes a liquid leakage detection device, the liquid leakage detection device includes a liquid leakage collection mechanism and a liquid leakage detection mechanism, wherein:

[0007] The leakage collection mechanism can be installed directly below the liquid storage device, a feed port is provided at the top of the leakage collection mechanism, and the diameter of the feed port is larger than the outer diameter of the liquid storage device, and a receiving cavity connected to the feed port is provided inside the leakage collection mechanism, and the receiving cavity is used to contain the liquid leaked from the liquid storage device;

[0008] The liquid leakage detection mechanism is fixedly arranged on the side wall of the bottom end of the liquid leakage collection mechanism, and is used to detect whether the liquid leakage is collected in the accommodating cavity of the liquid leakage collection mechanism;

[0009] The monitoring equipment can be installed in the peripheral space area of ​​the leakage detection mechanism, so that it can obtain real-time video information of the leakage detection mechanism.

[0010] The monitoring equipment is an existing technology and is briefly described here. It includes a monitoring camera and a host computer. The monitoring camera is installed in the peripheral space area of ​​the leakage detection mechanism so that it can obtain real-time images / video signals from the leakage detection equipment. The monitoring camera is communicated with the host computer and the video signal is transmitted to the host computer, which is then played or replayed in real time by the host computer. It can display regional alarm prompts and control the monitoring camera, making it convenient for staff to promptly detect leakage in the liquid storage device.

[0011] The leakage detection mechanism includes a first detection head, a second detection head and a test circuit, the two ends of the first detection head and the two ends of the second detection head are respectively set as connection ends and conductive ends, and the connection ends of the first detection head and the second detection head are respectively electrically connected to the two ends of the break point of the test circuit loop; the test circuit includes a detection power supply, wires and a signal load, and the connection end of the second detection head, the detection power supply, the signal load and the connection end of the first detection head are connected in series through wires in sequence. Specifically, the signal load is a light-emitting / acoustic-optical component, which can emit light / acoustic-optical signals in the working state.

[0012] A first opening and a second opening are provided on the side wall near the bottom end of the leakage collection mechanism, the first detection head is provided in the first opening and its conductive end extends into the accommodating cavity, the second detection head is provided in the second opening and its conductive end extends into the accommodating cavity; when there is no leakage in the accommodating cavity of the leakage collection mechanism, the first detection head and the second detection head are not conductive; when the leakage in the accommodating cavity submerges the first detection head and the second detection head, the first detection head and the second detection head are conductive. It should be noted that the conductive end of the first detection head and the conductive end of the second detection head are at a preset distance from each other, and preferably the first opening and the second opening are symmetrical about the central axis of the accommodating cavity, so that the leakage can conduct the test circuit to form a loop.

[0013] Through the above structure, when liquid leakage occurs in the liquid storage device, the leakage collection mechanism collects the leakage and when the leakage submerges the conductive ends of the first detection head and the second detection head, the liquid can make the first detection head and the second detection head electrically conductive, and the test circuit forms a closed loop to make the signal load work and emit a light / sound and light signal (alarm signal). When the monitoring equipment detects the alarm signal, it is displayed through the host computer, so that the staff can promptly discover the leakage of the liquid storage device; after the leakage fault is eliminated, the liquid in the leakage collection mechanism is removed, the alarm is lifted, and the leakage detection mechanism can return to normal working state.

[0014] As an option, based on the above scheme, in the improved scheme, the leakage collection mechanism is a funnel-shaped structure, which plays a role in gathering leakage. Preferably, the bottom of the accommodating chamber of the leakage collection mechanism is provided with a transition portion extending downward along its depth direction, and the transition portion is a hollow cylindrical structure, and the conductive end of the first detection head and the conductive end of the second detection head are respectively arranged on the side wall of the transition portion. In this way, the leakage is more likely to gather at the bottom of the leakage collection mechanism and be stored in the transition portion, and the transition portion is expanded relative to the collection mechanism to reduce its contact with the external liquid surface.

[0015] As an option, based on the above scheme, in the improved scheme, the bottom of the transition part extends downward along its depth direction to be provided with a collecting part, the collecting part is a funnel-shaped structure, the conductive end of the first detection head and the conductive end of the second detection head are respectively arranged on the side wall of the collecting part, and the first detection head and the second detection head are a certain distance from the inner bottom wall of the collecting part, such as 1cm or 1.5cm. In this way, the bottom end of the leakage collection mechanism sinks to form a cone structure, which can play a role in depositing impurities such as dust in the leakage, and compared with the bottom cylindrical structure, the cone structure has a smaller volume, and less liquid is required to flood the detection head to conduct the test circuit, and the required leakage identification time is shorter.

[0016] As an option, based on the above-mentioned scheme, in an improved scheme, the video surveillance device also includes two seals, and the two sealing sleeves are respectively arranged on the first detection head and the second detection head, and are respectively inserted into the first opening with the first detection head and the second detection head with the second detection head to achieve a sealed connection.

[0017] As an option, based on the above-mentioned solution, in an improved solution, a dustproof flip plate is provided in the accommodating chamber, and the dustproof flip plate is hingedly connected to the inner wall of the leakage collection mechanism.

[0018] As an option, the leakage collection mechanism is provided with a discharge port and a switch component used in conjunction with the discharge port. The discharge port is provided at the bottom end of the leakage collection mechanism. The switch component includes a discharge pipe and a switch valve. The discharge pipe is provided at the discharge port and is connected to the accommodating cavity. The switch valve is provided on the discharge pipe and can control the closing and opening of the discharge channel.

[0019] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0020] The utility model provides a video monitoring device with leakage recognition function. By converting whether a liquid storage device is leaking into monitoring whether a load is working, it can timely, accurately and effectively monitor whether the liquid storage device is leaking and issue an alarm, thereby avoiding the problem of being unable to timely and accurately monitor after a liquid storage device leaks. It also replaces manual patrols to monitor the liquid storage device, reduces labor costs and improves monitoring efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] See also Figure 1 A video monitoring device with leakage recognition function in this embodiment includes a monitoring device 10 capable of remote video monitoring, and also includes a leakage detection device, which includes a leakage collection mechanism 40 and a leakage detection mechanism 50.

[0032] Among them, the monitoring device 10 is an existing technology, which is briefly described as follows: the monitoring device 10 specifically includes a monitoring camera and a host computer, and the monitoring camera is installed in the peripheral space area of ​​the leakage detection mechanism 50, so that it can obtain the real-time image / video signal of the leakage detection device; the monitoring camera is connected to the host computer for communication, and the video signal is transmitted to the host computer, and then played or replayed in real time by the host computer, which can display the regional alarm prompt and control the monitoring camera, so that the staff can find the leakage of the liquid storage device 20 in time; it should be noted that the monitoring camera and the host computer are both applications of existing technologies, and the monitoring camera and the host computer can realize the long-distance transmission of data. The present application is to add a leakage detection device on the basis of the existing monitoring device, which collects the leakage and provides a conspicuous prompt signal (signal load), so that it is easier to watch the prompt signal in real time through the video monitoring device or watch the prompt signal through playback. The following will further explain the improvement point of the present application, the leakage detection device.

[0033] The leakage collection mechanism 40 is further described as follows:

[0034] See also Figure 1-Figure 3The leakage collection mechanism 40 is installed directly below the liquid storage device 20 through the bracket 30. A feed port 401 is provided at the top of the leakage collection mechanism 40. The diameter of the feed port 401 is larger than the outer diameter (width) of the liquid storage device 20, so that it can completely collect the leaked liquid from any place of the liquid storage device 20. A accommodating cavity 402 connected to the feed port 401 is provided inside the leakage collection mechanism 40. The accommodating cavity 402 is used to contain the liquid leaked from the liquid storage device 20; or, the leakage collection mechanism can be installed directly below the leakage area of ​​the liquid storage device, and the diameter of the feed port is larger than the width of the leakage area of ​​the liquid storage device.

[0035] The liquid storage device 20 can be used to store oil, water, slurry or other liquid materials, as long as the stored liquid is conductive, thereby ensuring that the leakage collection mechanism 40 can accurately determine whether there is leakage in the liquid storage device 20.

[0036] Here, the case where the diameter of the feed port 401 is larger than the outer diameter (width) of the liquid storage device 20 is used as an example for explanation: for example, the outer diameter of the liquid storage device 20 can be 1m, as long as it can accommodate a certain amount of conductive liquid for storage; when the outer diameter of the liquid storage device 20 is 1m, the diameter of the feed port 401 at the top of the leakage collection mechanism 40 can be 1.1m, and the axis of the feed port 401 coincides with the axis of the liquid storage device 20, thereby ensuring that the leakage of the liquid storage device 20 can be completely collected by the leakage collection mechanism 40. Of course, in an example of a leakage area structure, the diameter of the leakage area (drip) is 0.2m, and the diameter of the feed port is 0.3m, which will not be further described here.

[0037] Preferably, the leakage collection mechanism 40 has a funnel-shaped structure, that is, the top cross-section of the accommodating chamber 402 is larger than the bottom cross-section, and the inner wall of the accommodating chamber 402 is conical, which plays a role in guiding and converging, so as to facilitate the collection of leakage at the bottom of the accommodating chamber 402, and the first opening 403 and the second opening are symmetrically arranged on the side wall near the bottom of the leakage collection mechanism 40 along its axis.

[0038] The leakage detection mechanism 50 is further described:

[0039] The leakage detection mechanism 50 is fixedly arranged on the bottom side wall near the leakage collection mechanism 40, and is used to detect whether leakage is collected in the accommodating cavity 402 of the leakage collection mechanism 40. The leakage detection mechanism 50 includes a first detection head 501, a second detection head 502 and a test circuit. The two ends of the first detection head 501 and the two ends of the second detection head 502 are respectively set as connecting ends and conductive ends; the test circuit is arranged in the external space area of ​​the leakage collection mechanism 40, and it is an open circuit in its normal state. The connecting ends of the first detection head 501 and the second detection head 502 are respectively electrically connected to the two ends of the breaking point of the test circuit loop, and no conductive loop is formed.

[0040] The test circuit includes a detection power supply 5031, a wire 5032 and a signal load 5033, wherein the connection end of the second detection head 502, the positive electrode of the detection power supply 5031, the two ends of the signal load 5033 and the connection end of the first detection head 501 are connected in series through the wire (5032) in sequence; the signal load 5033 can be arranged on a side close to the monitoring device 10, so that the monitoring device 10 can clearly capture the video information of the signal load 5033. Specifically, the signal load 5033 can be a red LED lamp or other light-emitting device in the existing technology, or an audio-visual warning device. When the test circuit is turned on to form a loop, the signal load 5033 will emit a warning light source / audio-visual signal.

[0041] The conductive end of the first detection head 501 extends from the outside of the leakage collection mechanism 40 through the first opening 403 into the accommodating cavity 402, and the conductive end of the second detection head 502 extends from the outside of the leakage collection mechanism 40 through the second opening into the accommodating cavity 402; specifically, the first detection head 501 and the second detection head 502 should be arranged near the bottom end of the accommodating cavity 402 and located on the same horizontal plane, so that the leakage can easily submerge the conductive ends of the first detection head 501 and the second detection head 502.

[0042] In addition, there is a certain preset distance between the conductive end of the first detection head 501 and the conductive end of the second detection head 502. When there is no leakage in the leakage collection mechanism 40, the first detection head 501 and the second detection head 502 are not conductive to each other. When there is leakage in the leakage collection mechanism 40 and the leakage completely soaks the conductive ends of the first detection head 501 and the second detection head 502, the test circuit is conductive to form a closed loop. Because the conductivity of the liquid is affected by the distance (the longer the electrical conduction path, the weaker the current), the preset distance should be the distance at which the leakage can conduct the test circuit and form a loop.

[0043] Through the above-mentioned video monitoring device, when liquid leakage occurs in the liquid storage device 20, the liquid flows into the leakage collection mechanism 40, and the liquid collected in the leakage collection mechanism 40 floods the conductive ends of the first detection head 501 and the second detection head 502, so that the first detection head 501 and the second detection head 502 can be connected, and the test circuit is connected to form a closed loop to make the signal load 5033 work, that is, the red LED lamp or the sound and light warning device sends out a light / sound and light signal alarm, and the monitoring equipment 10 receives and displays the alarm area through the host computer, reminding the staff to take maintenance measures for the liquid storage device 20; when the leakage fault is eliminated, the liquid in the leakage collection mechanism 40 is removed, the alarm is lifted, and the leakage detection mechanism 50 returns to a normal working state. In this way, it is possible to accurately and effectively monitor whether the liquid storage device is leaking, thereby avoiding the problem of not being able to monitor the liquid storage device in a timely and accurate manner after the leakage occurs.

[0044] Example 2

[0045] On the basis of Example 1, the structure of the leakage collection mechanism 40 of Example 2 is different, and other identical structures are not repeated here. The leakage collection mechanism 40 of Example 2 is specifically as follows:

[0046] The bottom of the accommodating cavity 402 of the leakage collection mechanism 40 extends downward along its depth direction to set a transition part 405, which is a hollow cylindrical structure, i.e., cylindrical, square cylindrical, etc. In this way, setting the bottom of the leakage collection mechanism 40 into a columnar structure can make it easier for the leakage to gather at its bottom and be stored in the transition part, and the transition part is expanded relative to the collection mechanism to reduce its contact with the external liquid surface. And the preset distance between the conductive end of the first detection head 501 and the conductive end of the second detection head 502 is minimized as much as possible.

[0047] See also Figure 4 Based on the above examples, in a further preferred example, a collecting part 406 is provided at the bottom of the transition part 405 extending downward along the depth direction thereof, and the collecting part 406 is funnel-shaped, and the conductive end of the first detection head 501 and the conductive end of the second detection head 502 are respectively provided on the side walls of the collecting part 406, and the first detection head and the second detection head are at a certain distance from the inner bottom wall of the collecting part, such as 1 cm. By providing the collecting part 406, that is, the bottom end of the leakage collection mechanism is sunken to form a cone-shaped structure, on the one hand, when there are impurities such as dust in the leakage, the impurities can be slowly deposited in the collecting part, and when the leakage needs to be removed, the leakage can be recovered from the top of the collecting part; on the other hand, compared with the cylindrical structure at the bottom, the cone-shaped structure has a smaller volume, and less liquid is required to flood the detection head to conduct the test circuit, and the required leakage identification time is shorter.

[0048] Example 3

[0049] Based on Example 2, this Example 3 adds a dustproof structure, which is as follows:

[0050] See also Figure 2 , Figure 3 and Figure 5 A detachable dust-proof flip plate 60 is arranged in the accommodating cavity 402, and the dust-proof flip plate 60 is hingedly connected to the inner side wall at the top end of the transition portion 405. Specifically, two notches 407 are symmetrically provided on the inner side wall at the top end of the transition portion 405 along the central axis, and a connecting shaft 601 is arranged on the dust-proof flip plate 60 to match the notch 407. The connecting shaft 601 is inserted into the notch 407 so that the dust-proof flip plate 60 can rotate around its axis, wherein the shape of the dust-proof flip plate 60 is adapted to the shape of the opening at the top end of the transition portion 405 and a certain gap is reserved between the dust-proof flip plate 60 and the inner side wall of the transition portion 405 to ensure that the leaked liquid can flow into the collecting portion 406 from the gap; the dust-proof flip plate 60 can be made of lightweight plastic.

[0051] Through the dust-proof structure, when the leaked liquid of the liquid storage device 20 drips slowly, the leaked liquid is collected slowly in the leakage collection mechanism 40, and the dust in the air is easy to fall into and mix with the collected leaked liquid. The more dust impurities in the solution, the greater the resistivity, which will affect the conductivity of the liquid. Therefore, setting a dust-proof flip plate 60 can reduce the impurities and dust in the leaked liquid.

[0052] Based on the above example, as a further preferred example, the video monitoring device further includes two seals, which are sleeved on the first detection head 501 and the second detection head 502, and are inserted in the first opening 403 and the second opening for sealing connection. The seal is a rubber ring or a silicone ring. In this way, not only the first detection head 501 and the second detection head 502 are insulated from the side wall of the leakage collection mechanism 40, but also the leakage is prevented from seeping out of the first opening 403 or the second opening, thereby improving the sealing between the leakage detection mechanism and the leakage collection mechanism.

[0053] Based on the above examples, further as a preferred example, the leakage collection mechanism 40 of the video monitoring device is provided with a discharge port 407 and a switch member 80 used in conjunction with the discharge port. The discharge port 407 is provided at the bottom end of the leakage collection mechanism 40 and communicates with the accommodating chamber 402. The switch member 80 can be an elastic soft plug and has an interference fit with the discharge port 407. The switch member 80 can also be a switch valve installed and used in conjunction with the discharge port 407 (the switch member includes a discharge pipe and a switch valve, the discharge pipe is provided at the discharge port, and the switch valve is provided on the discharge pipe). By providing the discharge port 407, the leakage of the leakage collection mechanism 40 can be discharged through the discharge port 407, avoiding the need to manually disassemble the leakage collection mechanism 40 to pour out the leakage or use a liquid pump to remove the leakage when it is necessary to remove the liquid collected in the leakage collection mechanism 40, thereby facilitating the removal of the leakage.

[0054] As mentioned above, a video monitoring device with leakage recognition function of the utility model can replace manual patrols to monitor liquid storage devices, reducing labor costs. When a liquid storage bottle leaks, the video monitoring device can also promptly check the leakage and issue an alarm to improve monitoring efficiency.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. 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 claims of the present invention.
