Description

Technical Field

[0001] This utility model relates to the field of tank container technology, and in particular to a tank container liquid level detection device. Background Technology

[0002] Tank containers, also known as liquid cargo containers or liquid tank containers, are a type of container specifically designed for transporting various liquid goods, such as liquid chemicals, liquid food, various petroleum products, and alcoholic beverages. These containers are mainly composed of two parts: the liquid tank and the frame. The tank is the main body for transporting the goods, and its shape can be round, elliptical, or approximately spherical. The frame is usually made of steel or high-strength steel, and its dimensions and shape are the same as those of a regular container. The liquid tank is installed in the middle of the frame, hence the name liquid tank container.

[0003] Existing liquid level detection devices are often complex in structure, containing multiple components and complex mechanical or electronic systems. This not only increases manufacturing costs and leads to higher maintenance and repair costs, but also makes some electronic or optical liquid level detection devices susceptible to external environmental influences, such as temperature changes and electromagnetic interference, resulting in inaccurate detection results. Therefore, we propose a tank container liquid level detection device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tank container liquid level detection device.

[0005] This utility model is achieved using the following technical solution: a tank container liquid level detection device, comprising a tank container, a support rod fixedly connected to the inner wall of the tank container, a sliding collar slidably connected to the surface of the support rod, an auxiliary floating plate sleeved on the surface of the support rod, an external extension rod fixedly connected to the right end of the auxiliary floating plate, a connecting plate provided on the top of the tank container, a fixed plate fixedly connected to the bottom of the connecting plate, and a scale fixedly connected to the right end of the tank container.

[0006] With the above technical solution, when liquid enters the interior of the tank container, the auxiliary float plate rises with the increase in liquid level, causing the sliding collar to slide upward along the surface of the support rod. At the same time, it also causes the external extension rod to move upward. Since the external extension rod is fixedly connected to the connecting plate, the connecting plate also moves upward, causing the fixing plate to move upward, which in turn moves the position of the indicator plate. Because the indicator plate and the auxiliary float plate are on the same horizontal line, the height of the liquid inside the tank container can be determined by observing the position of the indicator plate and the scale. This makes it easier to see the liquid level more intuitively. The overall structure is simple and reduces the cost of subsequent maintenance.

[0007] As a further improvement to the above solution, the top of the sliding collar is fixedly connected to the bottom of the auxiliary floating plate, and the surface of the external extension rod is slidably connected to the inner wall of the tank container.

[0008] With the above technical solution, as the auxiliary float rises with the liquid level, the sliding collar slides along the support rod. The support rod limits the sliding collar, preventing the auxiliary float from tilting and ensuring that the auxiliary float and the indicator plate are always on the same horizontal line, thus improving the accuracy of the detection.

[0009] As a further improvement to the above solution, the top of the external extension rod extends to the outside of the tank container and is fixedly connected to the bottom of the connecting plate.

[0010] The above technical solution provides a sealing structure at the connection point between the external extension rod and the tank container, ensuring the sealing effect of the tank container without affecting the sliding of the external extension rod.

[0011] As a further improvement to the above solution, an indicator plate is fixedly connected to one end of the fixed plate, and the bottom of the indicator plate is at the same horizontal line as the bottom of the auxiliary floating plate.

[0012] As a further improvement to the above solution, a guide limiting plate is fixedly connected to the right end of the tank container, and the scale is located at the left end of the fixed plate.

[0013] The above technical solution allows for easy and intuitive observation of the liquid level using a ruler, improving ease of use.

[0014] As a further improvement to the above solution, a limiting groove is provided at one end of the guide limiting plate, and the guide limiting plate is L-shaped.

[0015] Through the above technical solution, the size of the limiting groove is adapted to the size of the fixing plate.

[0016] As a further improvement to the above solution, the inner wall of the limiting groove is slidably connected to the surface of the fixing plate.

[0017] With the above technical solution, when the fixed plate moves, it slides along the inner wall of the limiting groove, which limits the movement path of the fixed plate and prevents it from shifting or tilting during movement. This ensures that the fixed plate moves vertically, thereby improving the accuracy of liquid level detection and reducing errors.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes a supporting fixed rod, a sliding collar, an auxiliary float plate, an external extension rod, a connecting plate, a fixed plate, and a scale. Specifically, when liquid enters the tank container, the auxiliary float plate rises with the liquid level, causing the sliding collar to slide upwards along the surface of the supporting fixed rod. Simultaneously, the external extension rod moves upwards. Since the external extension rod is fixedly connected to the connecting plate, the connecting plate also moves upwards, causing the fixed plate to move upwards, thus shifting the position of the indicator plate. Because the indicator plate and the auxiliary float plate are at the same horizontal level, the liquid level inside the tank container can be determined by observing the corresponding positions of the indicator plate and the scale. This provides a more intuitive view of the liquid level. The overall structure is simple, reducing subsequent maintenance costs.

[0020] This invention improves the accuracy of liquid level detection and reduces errors by setting a guide limiting plate. Specifically, when the fixed plate moves, the fixed plate slides along the inner wall of the limiting groove, which limits the movement path of the fixed plate and prevents it from shifting or tilting during the movement. This ensures that the fixed plate moves vertically. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-5 This embodiment of a tank container liquid level detection device includes a tank container 1. A support rod 2 is fixedly connected to the inner wall of the tank container 1. A sliding collar 3 is slidably connected to the surface of the support rod 2. An auxiliary float plate 4 is sleeved on the surface of the support rod 2. An external extension rod 5 is fixedly connected to the right end of the auxiliary float plate 4. A connecting plate 6 is provided on the top of the tank container 1. A fixing plate 7 is fixedly connected to the bottom of the connecting plate 6. A scale 8 is fixedly connected to the right end of the tank container 1. When liquid enters the interior of the tank container 1, the auxiliary float plate 4 will move with the liquid level. As the height increases, the sliding collar 3 slides upward along the surface of the supporting fixed rod 2, which in turn moves the external extension rod 5 upward. Since the external extension rod 5 is fixedly connected to the connecting plate 6, the connecting plate 6 also moves upward, causing the fixed plate 7 to move upward and the indicator plate 9 to move. Since the indicator plate 9 and the auxiliary floating plate 4 are on the same horizontal line, the height of the liquid inside the tank container 1 can be determined by observing the corresponding position of the indicator plate 9 and the scale 8. This makes it easier to see the liquid level more intuitively. The overall structure is simple, reducing the cost of subsequent maintenance.

[0031] The top of the sliding collar 3 is fixedly connected to the bottom of the auxiliary floating plate 4, and the surface of the external extension rod 5 is slidably connected to the inner wall of the tank container 1.

[0032] The top of the external extension rod 5 extends to the outside of the tank container 1 and is fixedly connected to the bottom of the connecting plate 6.

[0033] An indicator plate 9 is fixedly connected to one end of the fixed plate 7. The bottom of the indicator plate 9 is at the same level as the bottom of the auxiliary floating plate 4.

[0034] A guide limit plate 10 is fixedly connected to the right end of the tank container 1, and a scale 8 is located at the left end of the fixed plate 7.

[0035] One end of the guide limiting plate 10 is provided with a limiting groove 11, and the guide limiting plate 10 is L-shaped.

[0036] The inner wall of the limiting groove 11 is slidably connected to the surface of the fixing plate 7.

[0037] The implementation principle of the liquid level detection device for a tank container in this embodiment is as follows: During use, liquid is poured into the tank container 1. When the liquid enters the tank container 1, the auxiliary float plate 4 rises with the increase in liquid level, causing the sliding collar 3 to slide upwards along the surface of the supporting fixed rod 2. Simultaneously, it also causes the external extension rod 5 to move upwards. Since the external extension rod 5 is fixedly connected to the connecting plate 6, the connecting plate 6 also moves upwards, causing the fixed plate 7 to move upwards, thus moving the position of the indicator plate 9. Because the indicator plate 9 and the auxiliary float plate 4 are on the same horizontal line, the height of the liquid inside the tank container 1 can be determined by observing the corresponding position of the indicator plate 9 and the scale 8. This provides a more intuitive view of the liquid level. The overall structure is simple, reducing subsequent maintenance costs. Simultaneously, when the fixed plate 7 moves, it slides along the inner wall of the limiting groove 11, limiting the movement path of the fixed plate 7 and preventing it from shifting or tilting during movement. This ensures that the fixed plate 7 moves vertically, thereby improving the accuracy of liquid level detection and reducing errors.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
