Description

Technical Field

[0001] The present invention relates to the field of detection equipment, and specifically to an integrated image liquid level monitor. Background Art

[0002] When detecting the environment to obtain environmental data, it is necessary to detect the water quality situation in the surrounding area; and when detecting the water quality, it is necessary to use a liquid level monitor to quickly obtain the liquid level situation at the position of the water area to be detected;

[0003] A liquid level monitor is provided in the related art. The liquid level monitor is composed of a control module, a wire, and a monitor body; the control module and the monitor body are connected by a coiled wire; the provided monitor body includes a housing and a liquid level pressure sensor installed inside the housing; the liquid level pressure sensor is located at the lower end of the housing;

[0004] When using this liquid level monitor, after the operator throws the monitor body into the position of the water area to be detected, then the monitor body falls in the water under the action of its own gravity until it finally reaches the bottom. Along with the fall of the position of the monitor body, the wire also changes from the wound state to the released state; the wire is not only used to tow the monitor body, but also is the medium for transmitting electrical signals between the monitor body and the control module; the liquid level pressure sensor transmits the measured pressure signal through the wire and finally converts the mechanical signal into an electrical signal at the position of the control module, and finally obtains the liquid level at the position of the water area to be detected;

[0005] This liquid level monitor is convenient to use and is also convenient to store when not in use later; but there are also some defects. For example, when the monitor body dives under the action of its own gravity for liquid level monitoring, the fluctuation of the water flow will cause turbulent shaking of the monitor body. In addition, the installed liquid level pressure sensor directly contacts the water flow frontally. If other impurities in the water are encountered during the diving process of the monitor body, these factors will ultimately affect the monitoring results of the liquid level monitor;

[0006] Aiming at the problems in the above background art, the present invention aims to provide an integrated image liquid level monitor. Summary of the Invention

[0010] A base, a sealing cover, and a monitoring cylinder. The base is installed at the upper end of the sealing cover; an adjusting mechanism is movably installed at the upper end of the base, which can adjust the operating angle and force direction of the entire integrated image liquid level monitor according to actual conditions; a control component is provided inside the sealing cover, and a Bluetooth signal transmitter is also installed at the upper end of the outer side of the sealing cover;

[0011] A monitoring cylinder is provided at the lower end of the sealing cover, and a detection mechanism for performing anti-interference accurate water level detection and underwater image information detection on the water area to be detected is installed inside the monitoring cylinder.

[0012] As a further scheme of the present invention: The adjusting mechanism includes a vertical rod, a movable seat, and a pressing component. The vertical rod is fixedly installed at the upper end of the movable seat, and the movable seat is movably installed on the base through a pin shaft; at the same time, a shock absorber is installed at the lower end of the movable seat, and the provided pressing component is located between the base and the sealing cover.

[0013] As a further scheme of the present invention: The pressing component includes an elastic plug, a movable rod, and a baffle. The elastic plug is installed at the upper end of the movable rod, and the movable rod is movably installed between the base and the sealing cover; a baffle is provided at the end part of the movable rod extending into the sealing cover; a compression spring is sleeved on the part of the movable rod between the elastic plug and the sealing cover.

[0014] As a further scheme of the present invention: An anti-disturbance protection cover is installed at the lower end of the monitoring cylinder. A pressure measuring chamber is formed between the anti-disturbance protection cover and the lower end of the monitoring cylinder. A pressure guiding hole is opened on one side of the pressure measuring chamber; the provided detection mechanism is located inside the pressure measuring chamber; the detection mechanism includes a liquid level detection component and an image detection component.

[0015] As a further scheme of the present invention: The liquid level detection component includes a strain gauge, a hydraulic medium, a pressure sensing sheet, and a pressure detector.

[0016] As a further scheme of the present invention: The image detection component includes a camera and a transparent protective cover. The camera is installed on one side of the anti-disturbance protection cover, and the transparent protective cover is arranged outside the camera; the provided image detection component and the liquid level detection component are both connected to the control component.

[0017] As a further scheme of the present invention: The control component includes an input transformer, a control module, and a storage battery. The input transformer and the storage battery are both electrically connected to the control module; the strain gauge and the camera are both electrically connected to the input transformer through conductive sheets.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] Compared with the current liquid level monitor, the integrated image liquid level monitor described above has the following advantages:

[0020] First, it changes the original single way of measuring the liquid level of the liquid level monitor. Instead, it is designed with a detection mechanism arranged inside the housing. The detection mechanism includes a liquid level detection component and an image detection component. In this way, the liquid level and image of the water area to be detected can be monitored simultaneously. At the same time, the detection mechanism is located inside the pressure measurement chamber, and the pressure measurement chamber is located between the anti-disturbance shield and the lower end of the monitoring cylinder. There is a pressure guiding hole on one side of the pressure measurement chamber. During the process of the monitoring cylinder diving, the anti-disturbance shield is used to reduce the shaking feeling caused by the water resistance encountered by the monitoring cylinder when diving in the water area to be detected, so as to improve the detection quality. When the monitoring cylinder dives to the specified water depth, water passes through the pressure guiding hole and enters the inside of the pressure measurement chamber, generating water pressure. Different water pressures are generated at different water depth positions, and different water pressures cause different mechanical vibration signals to the liquid level detection component. At the same time, since the water area to be detected passes through the pressure guiding hole and enters the inside of the pressure measurement chamber, rather than directly squeezing and contacting the pressure sensing sheet, it can effectively avoid other impurities in the water from hitting the pressure sensing sheet and affecting the detection result of the pressure sensing sheet. Furthermore, the monitoring error is finally reduced.

[0021] Second, it uses Bluetooth wireless signals to replace the current wire-based signals. In this way, there is no need to use long wires as a medium, which is convenient for reducing the occupied space in the later stage. At the same time, an adjustment mechanism is movably installed at the upper end of the base. The adjustment mechanism can adjust the state between the vertical rod and the monitoring cylinder, switching to a linear shape or a right-angled L shape. Making the vertical rod and the monitoring cylinder in a linear shape is convenient for reducing the occupied space of the entire integrated image liquid level monitor, and it can be convenient for storage and can also detect some small water areas at the detection port positions. When the vertical rod and the monitoring cylinder form a right angle, a lever arm can be provided on one side of the vertical rod, which is convenient for making the integrated image liquid level monitor dive under force and for slowly controlling the diving speed of the integrated image liquid level monitor at the monitoring water area position.

The provided adjusting mechanism can adjust the operating angle and force direction of the entire integrated image liquid level monitor according to actual conditions; a control component is provided inside the sealing cover 8, and a Bluetooth signal transmitter 7 is also installed at the upper end of the outer side of the sealing cover 8.

[0034] In an embodiment of the present invention, when using the integrated image liquid level monitor, for example, according to the water depth of the detected water area, the operating force angle direction of the entire integrated image liquid level monitor is changed through the provided adjustment mechanism.

[0035] Then, the water level of the water area to be detected and the specific underwater conditions are detected through the detection mechanism installed inside the monitoring cylinder 9; finally, the detection information result is wirelessly transmitted and discharged through the installed Bluetooth signal transmitter 7 by the provided control component.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 In an embodiment of the present invention, the adjustment mechanism includes a vertical rod 1, a movable seat 2, and a pressing component. The vertical rod 1 is fixedly installed at the upper end of the movable seat 2, and the movable seat 2 is hinged and movably installed on the base 5 through a pin shaft 4; at the same time, a shock absorber plug 3 is installed at the lower end of the movable seat 2, and the provided pressing component is located between the base 5 and the sealing cover 8.

[0037] In an embodiment of the present invention, for example, when lateral force needs to be applied to the integrated image liquid level monitor, when the vertically installed vertical rod 1 and the base 5 are adjusted to a right-angled vertical state, and then the movable seat 2 is rotated around the base 5 so that the vertical rod 1 installed on one side of the movable seat 2 forms a vertical state with the base 5, the provided pressing component automatically causes a pressing state at the position of the shock absorber plug 3 installed at the lower end of the movable seat 2, so that the adjusted vertical rod 1 in a right-angled state is locked and fixed.

[0038] When vertical force needs to be applied to the integrated image liquid level monitor, the movable seat 2 is rotated around the base 5 so that the vertical rod 1 installed on one side of the movable seat 2 forms a straight line state with the base 5, and the provided pressing component automatically causes a pressing state at the position of the shock absorber plug 3 installed at the lower end of the movable seat 2, so that the adjusted vertical rod 1 in a straight line state is pressed and fixed.

[0039] Please refer to Figure 3, in an embodiment of the present invention, the pressing assembly includes an elastic plug 6, a movable rod 12 and a baffle 13. The elastic plug 6 is installed at the upper end of the movable rod 12, and the movable rod 12 is movably installed between the base 5 and the sealing cover 8; a baffle 13 is provided at the end of the movable rod 12 extending into the sealing cover 8; a compression spring 11 is sleeved on the part of the movable rod 12 between the elastic plug 6 and the sealing cover 8;

[0040] The provided elastic plug 6 automatically approaches the shock-absorbing plug 3 at the lower end of the movable seat 2 under the action of the elastic force generated by the deformation of the compression spring 11, and always performs a pressing operation on the position of the shock-absorbing plug 3; a straight line is formed between the vertical rod 1 and the monitoring cylinder 9, which is convenient for reducing the floor space of the entire integrated image liquid level monitor, and can be convenient for storage and can also detect some small detection waters at the detection port positions; when the vertical rod 1 and the monitoring cylinder 9 are formed into a right angle state, a lever arm can be provided on one side of the vertical rod 1, which is convenient for the integrated image liquid level monitor to dive under force;

[0041] Please refer to Figure 4 , in an embodiment of the present invention, an anti-disturbance shield 23 is installed at the lower end of the monitoring cylinder 9, and a pressure measurement chamber 24 is formed between the anti-disturbance shield 23 and the lower end of the monitoring cylinder 9. A pressure guiding hole 22 is opened on one side of the pressure measurement chamber 24; the provided detection mechanism is located inside the pressure measurement chamber 24; the detection mechanism includes a liquid level detection component and an image detection component;

[0042] During the process of the monitoring cylinder 9 diving, the provided anti-disturbance shield 23 is used to reduce the shaking feeling caused by the water resistance encountered by the monitoring cylinder 9 when diving in the water area to be detected, so as to improve the detection quality; when the monitoring cylinder 9 dives to the specified water depth, water passes through the pressure guiding hole 22 and enters the pressure measurement chamber 24 to generate water pressure. Different water pressures are generated at different water depth positions, and different water pressures cause different mechanical vibration signals to the liquid level detection component. The liquid level detection component can detect the liquid level situation at the specified position; and the provided image detection component can perform real-time image detection on different water depth positions;

[0043] Specifically, the liquid level detection component includes a strain gauge 18, a hydraulic medium 20, a pressure sensing sheet 21 and a pressure detector 19. The pressure sensing sheet 21 is located at the upper end of the pressure measurement chamber 24, and the hydraulic medium 20 is filled between the strain gauge 18 and the pressure sensing sheet 21; the pressure detector 19 is located at both ends of the hydraulic medium 20;

[0044] When reaching the specified water area, the water source at the specified water area position passes through the pressure guiding hole 22 and enters the pressure measuring chamber 24. After the water source enters the interior of the pressure measuring chamber 24, it will exert pressure on the pressure sensing sheet 21, and the generated pressure will be transmitted to the hydraulic medium 20. Then, the pressure is transmitted to the strain gauge 18 through the hydraulic medium 20. The water pressures at different water depth positions are different, and the corresponding generated pressure signals are also different. Finally, it will be fed back to the control component through the pressure detector 19, and the liquid level signal at the specified position will be measured ultimately. At the same time, since the water area to be detected passes through the pressure guiding hole 22 and enters the interior of the pressure measuring chamber 24, rather than directly squeezing and contacting the pressure sensing sheet 21, it can effectively avoid other impurities in the water from hitting the pressure sensing sheet 21 and affecting the detection result of the pressure sensing sheet 21.

[0045] Specifically, the image detection component includes a camera 25 and a transparent protective cover 26. The camera 25 is installed on one side of the anti-disturbance shield 23, and the transparent protective cover 26 is arranged outside the camera 25. The set image detection component and the liquid level detection component are both connected to the control component.

[0046] Please refer to Figure 4 and Figure 5 In an embodiment of the present invention, the control component includes an input transformer 16, a control module 14, and a storage battery 15. The input transformer 16 and the storage battery 15 are both electrically connected to the control module 14. The strain gauge 18 and the camera 25 are both electrically connected to the input transformer 16 through conductive sheets 17.

[0047] The storage battery 15 provides electrical energy for the operation of the entire integrated image liquid level monitor. The installed control module 14 is used to control the operation state of the entire integrated image liquid level monitor. The detection mechanism generates a detection signal, which is the signal source 27. The signal source 27 includes the mechanical signal 28 generated by the liquid level detection component and the optical image signal 29 generated by the image detection component. The input mechanical signal 28 and the optical image signal 29 are both subjected to signal conversion through the input transformer 16, switched into electrical signals and then output to the control module 14. Then, it is output to the Bluetooth signal transmitter 7 through the control module 14. After the Bluetooth signal transmitter 7 emits wireless signals, finally, the signal is received through the Bluetooth signal receiver 30, thereby achieving the acquisition of the detection result.
