Description

Technical Field

[0001] This invention belongs to the field of opaque container liquid level detection technology, and more specifically, relates to a device and a container for detecting the liquid level in an opaque container. Background Technology

[0002] Liquid storage tanks or water tanks are typically made of opaque materials such as stainless steel or fiberglass. These tanks usually have inlets and vents at the top for filling with water and venting air. Because stainless steel and fiberglass are opaque, the internal liquid level cannot be seen from the outside. When the internal liquid level needs to be checked, it can only be seen by opening the inlet or outlet, which is inconvenient and makes it difficult to detect situations like low liquid levels. The inability to directly observe the internal liquid level from the outside can, in severe cases, affect normal production or use. Summary of the Invention

[0003] The purpose of this invention is to provide a device and a container for detecting the liquid level in an opaque container, thereby solving the technical problem that it is not easy to see the internal liquid level of an opaque container from the outside.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a device for detecting the liquid level in an opaque tank, comprising:

[0005] The pipe has one end inserted into the tank from the water inlet at the top and the other end placed outside the tank. The end of the pipe that extends into the tank is placed inside the tank near the bottom, allowing liquid inside the tank to enter the pipe.

[0006] A float is placed inside the pipe and floats on the surface of the liquid. The float rises and falls with the liquid level in the tank.

[0007] The rope has one end inserted into the pipe and connected to the upper end of the float, and the other end extends out from the outside of the pipe and is placed on the outer wall of the tank.

[0008] A counterweight is attached to the outer end of the rope. The weight of the float is greater than the weight of the counterweight, and the counterweight rises and falls with the rise and fall of the float.

[0009] A liquid level indicator is affixed to the outer wall of the tank. Various different colored height stickers are arranged sequentially along the height direction of the tank. The weight is placed at different heights, corresponding to different colored height stickers, to indicate the liquid level height value inside the tank.

[0010] As another embodiment of this application, the device for detecting the liquid level in an opaque tank further includes:

[0011] A sensor alarm is connected to the liquid level indicator and is used to sense the height of the counterweight. When the counterweight is within the sensing range of the sensor alarm, the sensor alarm will issue an alarm signal.

[0012] In another embodiment of this application, a sealing plug is provided inside the water inlet, and the sealing plug is provided with a water inlet hole and a detection hole. One end of the pipe is inserted into the tank through the detection hole. The outer wall of the pipe is sealed to the sealing plug. A plug is provided inside the water inlet hole. The water inlet hole is opened to add water into the tank.

[0013] In another embodiment of this application, the pipe is S-shaped, and the pipe placed inside the tank is arc-shaped and adapted to the arc shape of the inner wall of the tank. The pipe is close to but does not contact the inner wall of the tank. Liquid in the tank enters the inside of the pipe, and the liquid level in the pipe is the same as the liquid level in the tank.

[0014] In another embodiment of this application, the pipe is rotatably sealed to the detection hole, and an actuator is provided on the outer wall of the tank. The power output end of the actuator is connected to one end of the pipe extending out of the tank. The actuator is used to drive the pipe to rotate circumferentially in the detection hole so that the pipe placed inside the tank agitates the liquid inside the tank.

[0015] In another embodiment of this application, the driver is electrically connected to a wireless communication module. The device for detecting the liquid level in an opaque tank also includes a remote controller that is wirelessly connected to the driver. The remote controller has control buttons for remotely controlling the operation of the driver.

[0016] In another embodiment of this application, the liquid level indicator includes a low liquid level zone, a lower liquid level zone, a medium liquid level zone, a higher liquid level zone, and a high liquid level zone arranged sequentially from top to bottom. The sensor alarm is located in the low liquid level zone and is used to sense the weight located in the low liquid level zone.

[0017] In another embodiment of this application, the sensor alarm is wirelessly connected to the remote control, and the remote control has a display for displaying alarm information of the sensor alarm.

[0018] In another embodiment of this application, a plug is provided at one end of the pipe extending out of the tank, the plug being used to seal and prevent the liquid in the pipe from flowing to the outside of the tank.

[0019] The beneficial effects of the device for detecting the liquid level in an opaque tank provided by this invention are as follows: Compared with the prior art, the device for detecting the liquid level in an opaque tank includes a pipe, a float, a rope, a counterweight, and a liquid level indicator. One end of the pipe is inserted into the tank from the upper inlet, and the other end is placed outside the tank. The end of the pipe extending into the tank is placed inside the tank near the bottom, allowing the liquid in the tank to enter the pipe. The float is placed inside the pipe and floats on the liquid surface, rising and falling with the liquid level in the tank. The rope... One end of the body extends into the pipe and connects to the upper end of the float, while the other end extends out from the outside of the pipe and is placed on the outer wall of the tank. A counterweight is connected to the outer end of the rope. The weight of the float is greater than the weight of the counterweight, and the counterweight rises and falls with the float. A liquid level indicator is affixed to the outer wall of the tank. Various different colored height stickers are arranged sequentially along the height of the tank. Different colored height stickers correspond to different heights of the counterweight to indicate the liquid level in the tank. The liquid level can be directly indicated from the outside of the tank, making the liquid level indication convenient. It does not require opening the inlet and has a high degree of visibility.

[0020] The present invention also provides a tank, including a tank body and a device as described in any of the preceding claims for detecting the liquid level in an opaque tank.

Detailed Implementation

[0030] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] Please refer to the following: Figures 1 to 6 The present invention provides a device for detecting the liquid level in an opaque tank. The device includes a pipe 1, a float 2, a rope 3, a weight 4, and a liquid level indicator 5. One end of the pipe 1 is inserted into the tank 6 through the inlet 61 at the top, and the other end is placed outside the tank 6. The end of the pipe 1 extending into the tank 6 is positioned inside the tank 6 near the bottom, allowing liquid to enter the pipe 1. The float 2 is placed inside the pipe 1 and floats on the liquid surface. The float 2 rises with the liquid level in the tank 6. The float 2 rises and falls with the water level. One end of the rope 3 extends into the pipe 1 and is connected to the upper end of the float 2. The other end extends out from the outside of the pipe 1 and is placed on the outer wall of the tank 6. The weight of the float 2 is greater than the weight of the weight 4. The weight 4 rises and falls with the float 2. The liquid level indicator is affixed to the outer wall of the tank 6. Various different colored height stickers are arranged along the height direction of the tank 6. The weight 4 is placed at different heights, and there are different colored height stickers to indicate the liquid level height value inside the tank 6.

[0032] This invention provides a device for detecting the liquid level in an opaque tank. Compared with existing technologies, it can directly indicate the height of the internal liquid level from the outside of the tank 6, making the liquid level indication convenient without opening the inlet 61, and providing a high degree of visualization. The pipe 1 is a hollow tube with a certain degree of rigidity and flexibility, extending into the tank 6 from the inlet 61. It can also pass through the detection hole 63 on the sealing plug 62, allowing the float 2 to be placed inside. The float 2 will not get stuck inside the pipe 1 and can freely rise and fall with the liquid level. In this embodiment, the weight 4 also refers to a marker, its function being to indicate the height of the float 2 for the operator to see. The liquid inside the tank 6 will not flow out from the inlet 61, and of course, the liquid inside the pipe 1 will not flow out from the protruding end of the pipe 1 (defined as the outer end), because the height of the outer end is greater than the maximum liquid level height inside the tank 6.

[0033] As a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link / reference needed]. Figures 1 to 6 The device for detecting the liquid level in the opaque tank also includes a sensor alarm 7, which is connected to the liquid level indicator and senses the height of the weight 4. When the weight 4 is within the sensing range of the sensor alarm 7, the sensor alarm 7 emits an alarm signal. The sensor functions as an alarm, promptly alerting personnel to prevent the liquid level in the tank 6 from becoming too low, which could affect subsequent production or use. When the liquid level is low, personnel can open the water inlet to add water to the tank 6. Specifically, the sensor alarm 7 includes a sensor and an alarm.

[0034] Rope 3 is a flexible rope that can deform and move freely within pipe 1, allowing for precise control of the movement of the weight 4. The float 2 has a certain weight, and its density is less than that of the liquid inside tank 5, thus allowing it to float on the liquid surface.

[0035] As a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link / reference needed]. Figures 1 to 6 A sealing plug 62 is installed inside the water inlet 61. The sealing plug 62 has a water inlet hole 64 and a detection hole 63. One end of the pipe 1 is inserted into the tank 6 through the detection hole 63. The outer wall of the pipe 1 is sealed to the sealing plug 62. A plug 65 is installed inside the water inlet hole 64. Opening the water inlet hole 64 allows water to be added into the tank 6. The sealing plug 62 serves two purposes: firstly, it prevents liquid from flowing out of the tank 6, and secondly, it provides rotational support for the pipe 1. The longitudinal cross-section of the sealing plug 62 is an inverted frustum shape, with the outer diameter of the upper end being larger than that of the lower end. It can only block the water inlet 61 with external force. Due to its own structural factors, it cannot fall into the tank 6.

[0036] As a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link / reference needed]. Figures 1 to 6 Pipe 1 is S-shaped and is located inside tank 6. Pipe 1 is arc-shaped and conforms to the arc shape of the inner wall of tank 6. Pipe 1 is close to but does not contact the inner wall of tank 6. Liquid in tank 6 enters into pipe 1, and the liquid level in pipe 1 is the same as the liquid level in tank 6. The purpose of setting pipe 1 in an S-shape is twofold: first, it allows liquid in tank 6 to enter into pipe 1, making it easy to observe the liquid level from outside tank 6; second, it allows for thorough stirring of the liquid in tank 6. When pipe 1 rotates, the liquid is in a state of agitation, and the upper end of pipe 1 does not contact the sealing plug 62 or the inlet 61.

[0037] As a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link / reference needed]. Figures 1 to 6 The pipe 1 is rotatably sealed to the detection hole 63. An actuator 8 is installed on the outer wall of the tank 6. The power output end of the actuator 8 is connected to the end of the pipe 1 extending out of the tank 6. The actuator 8 drives the pipe 1 to rotate circumferentially within the detection hole 63, thereby agitating the liquid inside the tank 6. In this embodiment, the rotatable sealing connection can be achieved using a rotary sealing ring, meaning that the pipe 1 can maintain a seal with the sealing plug 62 while rotating, or that the gap between the two is sealed, preventing liquid from flowing out of the tank 6 from the gap between the sealing plug 62 and the pipe 1. It is important to note that during the rotation of the pipe 1, the rope 3 will move a certain distance, but will not twist or otherwise affect the indication or detection of the liquid level inside the tank 6. The upper end of the pipe 1 extends horizontally or obliquely towards the outer wall of the tank 6 after extending out of the tank 6. This is to facilitate the rope 3's contact with the outer wall of the tank 6, better indicating the liquid level.

[0038] Typically, the driver 8 is a geared motor capable of both forward and reverse rotation, thus driving the pipe 1 to rotate clockwise or counterclockwise. The pipe 1 stops rotating after a certain period of time. Figure 5 It rotates back and forth within the angle range indicated by α. Moreover, it does not move into the tank 6 during the rotation, thus ensuring the normal use of the pipeline 1.

[0039] Typically, the rotation angle of pipe 1 is between -30° and 30°, such as Figure 5 The angle α shown in the figure means that pipe 1 can rotate 60°, which ensures that pipe 1 will not be touched and will not affect the normal use of pipe 1.

[0040] To enable remote control of the actuator 8 and facilitate remote operation by staff, as a specific embodiment of the device for detecting the liquid level in an opaque tank provided by this invention, please refer to [link to specific implementation]. Figures 1 to 6 The actuator 8 is electrically connected to a wireless communication module. The device for detecting the liquid level inside the opaque tank 6 also includes a remote controller 9 wirelessly connected to the actuator 8. The remote controller 9 has control buttons for remotely controlling the operation of the actuator 8. In this embodiment, the remote controller 9 can be a prior art product, equipped with a mobile communication module that wirelessly connects to the wireless communication module. Both modules are existing electronic products, enabling real-time wireless communication between the remote controller 9 and the actuator 8. The actuator 8 can be controlled from the remote controller 9, thus agitating the liquid inside the tank 6 and solving the technical problems of clumping and solidification within the tank 6. Alternatively, it is necessary for a dedicated person to open the inlet 61 to agitate the liquid, which is labor-intensive. By using a pipe 1 that can perform a stirring function, a dual-purpose technical effect is achieved.

[0041] As a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link / reference needed]. Figures 1 to 6 The liquid level indicator 5 includes, from top to bottom, a low liquid level zone 51, a lower liquid level zone 52, a medium liquid level zone 53, a higher liquid level zone 54, and a high liquid level zone 55. A sensor alarm 7 is installed in the low liquid level zone 51 and is used to sense the weight 4 located in the low liquid level zone 51. When the weight 4 is in the low liquid level zone 51, the sensor alarm 7 will generate an alarm signal, thereby reminding staff to pay attention to adding liquid. The various zones can be represented by different colored cards, such as red for the low liquid level zone 51 and orange for the lower liquid level zone 52, etc.

[0042] In order to enable the alarm information of the sensor alarm 7 to be displayed on the remote control 9 in real time, as a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link to specific embodiment]. Figures 1 to 6 The sensor alarm 7 is wirelessly connected to the remote control 9, which has a display screen on the remote control 9 to show alarm information from the sensor alarm 7. This display screen can show alarm information. When an operator holds the remote control 9 and sees an alarm message, they can know that the liquid level is low and be reminded to add liquid to the tank 6.

[0043] As a specific embodiment of the device for detecting the liquid level in an opaque tank provided by the present invention, please refer to [link / reference needed]. Figures 1 to 6A plug 10 is inserted through one end of the pipe 1 that extends out of the tank 6. The plug 10 is used to seal and prevent the liquid in the pipe 1 from flowing to the outside of the tank 6. When the present invention is not used, the plug 10 can be used to seal the outer end of the pipe 1 so that the liquid in the tank 6 will not leak out. When the present invention is used, the plug 10 can be removed from the pipe 1 or placed in a position that does not affect the movement of the rope 3.

[0044] The present invention also provides a tank body 6. Please refer to [link / reference]. Figure 1 The tank 6 includes a tank body and a device for detecting the liquid level inside the opaque tank, as described above.

[0045] The tank 6 provided by the present invention employs a device for detecting the liquid level inside the opaque tank 6, which can directly indicate the height of the internal liquid level from the outside of the tank 6. The liquid level is easy to indicate, and there is no need to open the inlet 61, resulting in a high degree of liquid level visualization.

[0046] As one specific embodiment of the tank provided by the present invention, see [reference needed]. Figure 1 The tank 6 is an opaque type, such as a liquid storage tank, a stainless steel tank, or a water tank.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
