Description

Technical Field

[0001] This utility model relates to the field of tanker capacity detection technology, and in particular to a device for detecting the capacity of hazardous chemical tankers. Background Technology

[0002] With the rapid development of China's transportation industry, ensuring the safety of road transport of dangerous goods has become a focus of national and societal attention. As the country continues to deepen its efforts in regulating tank trucks carrying atmospheric pressure liquid dangerous goods, the importance of tank truck capacity has become even more prominent. Dangerous chemical tank trucks are special-purpose vehicles used to transport highly toxic chemicals and other chemicals that possess properties such as toxicity, corrosiveness, explosiveness, flammability, and combustion-supporting properties, posing a threat to human health, facilities, and the environment.

[0003] According to patent number CN218885107U, a utility model patent for a device for verifying the capacity of oil tankers includes a platform, a main outlet pipe, a main drain pipe, and a water storage tank. The platform is equipped with a first metal measuring instrument and a second metal measuring instrument. The main outlet pipe is located on the platform and is connected to the first metal measuring instrument via a first branch pipe and a second branch pipe. The main drain pipe is also located on the platform, and is connected to both the first and second metal measuring instruments. The water storage tank is located on the ground below the platform and is equipped with a first water pump and a second water pump. Both pumps are connected to the water storage tank. The water storage tank contains a separation structure capable of separating oil and water. This utility model can simultaneously verify the capacity of oil tankers using volumetric methods, mass methods, and flow valves, reducing detection errors and enabling the recycling of water resources.

[0004] While the above technical solution can detect the volume of tank trucks, the method of measurement using an electronic weighbridge affects the accuracy of the volume detection. Furthermore, in practical applications, the accuracy of the detection results needs to be reduced by decreasing the air content, but this technical solution does not meet this requirement. Utility Model Content

[0005] The purpose of this invention is to provide a capacity detection device for hazardous chemical tank trucks, which can detect the volume of tank trucks and reduce the air content during detection, thereby improving the accuracy of tank truck volume detection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A capacity detection device for hazardous chemical tank trucks includes a sunken water storage tank on the ground, an air deflator installed on one side of the water storage tank, a first level gauge installed along the height direction on one side of the inner wall of the water storage tank, a float plate floating on the water surface of the water storage tank, a first temperature sensor installed at the upper end of the float plate and passing through its lower end, a water pump installed on one side of the water storage tank, an inlet of the water pump connected to an inlet pipe extending to the bottom of the inner wall of the water storage tank, a filter installed on one side of the water pump, and a water guide pipe connected to both the outlet of the water pump and the inlet of the filter.

[0008] A U-shaped support frame is provided on one side of the filter. A water supply pipe is provided along the length of the upper end of the inner wall of the support frame. A water outlet pipe is provided between the outlet of the filter and one end of the water supply pipe, and the deaerator is installed between the water outlet pipe and the water supply pipe. A corrugated pipe is provided at the other end of the water supply pipe, and a control component is provided at the lower end of the corrugated pipe. A control cabinet is installed on one side of the outer wall of the support frame. The water pump, the first level gauge, and the first temperature sensor are all electrically connected to the control cabinet.

[0009] By adopting the above technical solution, when using the device, first power it on, then drive the chemical tanker to be tested into the support frame and position its inlet at the control component. Then operate the control cabinet to make the water pump work. The water pump draws water from the storage tank through the inlet pipe, allowing it to flow into the filter through the first guide pipe, then into the temperature control component through the second guide pipe, and finally into the water supply pipe through the outlet pipe. Then open the control component to allow the water to flow into the tank of the chemical tanker. During this process, the first level gauge and the first temperature sensor monitor the water level and temperature changes in the storage tank in real time, while the deaerator will expel as much air as possible from the water to improve the accuracy of the test results. When the tanker is full of water, the tank capacity can be calculated by combining the current water temperature and the amount of water entering the tank.

[0010] A further feature of this invention is that: the left and right sides of the inner wall of the water storage tank are recessed inward along their height direction and have sliding grooves, and a connecting rod that can float on the water surface and is fixedly connected to the float plate is slidably connected in the two sliding grooves.

[0011] By adopting the above technical solution, it can be ensured that the float will not shake significantly when pumping water from the reservoir.

[0012] A further feature of this invention is that the control component includes a flow meter, a positioning sleeve installed at the lower end of the flow meter and communicating with it, a second temperature sensor installed on one side of the outer wall of the positioning sleeve and extending into it, and a second level gauge installed on one side of the outer wall of the positioning sleeve.

[0013] By adopting the above technical solution, not only can the temperature of the water entering the tank be controlled by the first temperature sensor, thus improving the accuracy of the detection results, but the cooperation of the first and second level gauges can also be used for auxiliary verification.

[0014] A further feature of this invention is that a solenoid valve is installed at the lower end of the positioning sleeve and communicates with it.

[0015] By adopting the above technical solution, when the water entering the tanker reaches the appropriate position, the water can be quickly intercepted by the solenoid valve.

[0016] In summary, this utility model has the following beneficial effects:

[0017] Firstly, this utility model can detect the volume of tank trucks, and during the detection process, it can detect changes in water temperature and reduce the air content in the water, thereby improving the accuracy of tank truck volume detection.

[0018] Secondly, the corrugated pipe of this utility model can not only adjust its length according to the height of the tank truck, making it convenient to use on tank trucks of different sizes, but also control the height of the water level detected by the second level gauge according to the actual situation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Example, refer to Figs. 1-3 A capacity detection device for hazardous chemical tank trucks includes a sunken water storage tank 1 on the ground, an air degasser 23 on one side of the water storage tank 1, a first level gauge 11 installed along the height direction on one side of the inner wall of the water storage tank 1, a float plate 14 floating on the water surface of the water storage tank 1, a first temperature sensor 15 installed at the upper end of the float plate 14 and passing through its lower end, a sliding groove 12 recessed inward on the left and right sides of the inner wall of the water storage tank 1 along the height direction, a connecting rod 13 that can float on the water surface and is fixedly connected to the float plate 14 is slidably connected in the two sliding grooves 12, and a water pump 16 is installed on one side of the outer wall of the water storage tank 1, and the inlet of the water pump 16 is connected to an inlet pipe 17 extending to the bottom of the inner wall of the water storage tank 1.

[0028] A filter 18 is installed on one side of the water pump 16. The water inlet of the filter 18 is top-inlet and bottom-outlet. A water guide pipe 19 is provided between the outlet of the water pump 16 and the inlet of the filter 18. A U-shaped support frame 2 is provided on one side of the filter 18. A water conveying pipe 22 is provided along the length of the upper end of the inner wall of the support frame 2. A water outlet pipe 24 is provided between the outlet of the filter 18 and one end of the water conveying pipe 22. An air deaerator 23 is installed between the water outlet pipe 24 and the water conveying pipe 22. A corrugated pipe 25 is provided at the other end of the water conveying pipe 22.

[0029] A control component 26 is provided at the lower end of the bellows 25 and is connected to it. The control component 26 includes a flow meter 27, a positioning sleeve 28 installed at the lower end of the flow meter 27 and connected to it, a second temperature sensor 29 installed on one side of the outer wall of the positioning sleeve 28 and extending into it, and a second level gauge 3 installed on one side of the outer wall of the positioning sleeve 28. A solenoid valve 31 is installed at the lower end of the positioning sleeve 28 and is connected to it. The lower end of the second level gauge 3 extends beyond the lower end of the solenoid valve 31. A control cabinet 21 is installed on one side of the outer wall of the support frame 2. The water pump 16, the first level gauge 11, the first temperature sensor 15, the second level gauge 3, the second temperature sensor 29 and the solenoid valve 31 are all electrically connected to the control cabinet 21.

[0030] Usage: First, power on the device. Then, drive the chemical tanker to be tested into the support frame 2 and position its inlet at the control component 26. The operator pulls the bellows 25 to extend the lower end of the control component 26 into the appropriate position inside the tank and fixes it in place. Then, operate the control cabinet 21 to make the water pump 16 work. The water pump 16 draws water from the water storage tank 1 through the water inlet pipe 17 and lets it flow into the filter 18 through the water guide pipe 19 for filtration, and then into the water supply pipe 22 through the water outlet pipe 24. Then, open the control component 26 and the solenoid valve 31 to let the water flow into the tank of the chemical tanker. During this process, the first level gauge 11 and the first temperature sensor 15 on the float 14 monitor the water level and temperature changes in the water storage tank 1 in real time.

[0031] When the water level in the reservoir 1 drops, the connecting rod 13 ensures that the float 14 slides along the chute 12, preventing the eddies generated during pumping from affecting the stability of the float 14. The deaerator 23 will expel as much air as possible from the water, improving the accuracy of the detection results. The second temperature sensor 29 on the positioning sleeve 28 will monitor the temperature of the water flowing into the tank truck in real time. The temperature detected by the second temperature sensor 29 will be compared with the temperature detected by the first temperature sensor 15. The flow meter 27 will monitor the amount of water entering the tank in real time. When the liquid level in the tank truck reaches the detection position of the second level gauge 3, the solenoid valve 31 will automatically close, preventing water from continuing to enter the tank truck. Then, the tank capacity can be calculated by combining the current water temperature and the amount of water entering the tank. The initial water level detected by the first level gauge 11 and the temperature difference between the water before and after the tank can be used for auxiliary calculation.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
