Description

Technical Field

[0001] The utility model relates to the technical field of oil storage tanks, and more specifically to an automatic measuring device for oil tank detection. Background Art

[0002] The oil tank detection automatic measuring device is an automated device used to detect the internal status of the oil tank and ensure the safe operation of the oil tank. These devices usually integrate a variety of sensors and measurement technologies to monitor the key parameters of the oil tank in real time, such as liquid level, temperature, pressure, and whether there is leakage.

[0003] Due to the flammable and explosive characteristics of refined oil stored in oil tanks, it is necessary to monitor the storage status of the oil tanks in real time during the storage process, and keep abreast of the status of the oil in the oil tanks, such as liquid level information, temperature information, etc. The measurement of the oil reserves inside the oil tank can be achieved through a float-type electronic liquid level gauge. The current traditional float-type electronic liquid level gauge is usually composed of a long rod and a float. The float moves up and down with the rise and fall of the oil, thereby converting the position change of the float into an electrical signal to obtain liquid level information. However, this measurement structure can generally only achieve accurate measurement when the oil level changes slightly when used. When the oil tank is in the state of refueling or draining, the liquid level of the oil in the oil tank fluctuates greatly, and the depth of the oil will also change greatly in a short period of time. When the liquid level fluctuates, it is easy to cause the height of the float to change, thereby affecting the accuracy of real-time detection of liquid level information. In view of this, we propose an automatic measurement device for oil tank detection. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide an automatic measuring device for oil tank detection to solve the technical problem that when the current measuring structure is in use, when the oil tank is in the state of refueling or draining, the liquid level fluctuation amplitude of the oil in the oil tank is large, which affects the accuracy of real-time detection of liquid level information.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an oil tank detection automatic measuring device, comprising an oil tank with an oil storage bin formed inside;

[0006] The top of the oil storage tank is detachably provided with a top cover, and the inside of the oil storage tank is provided with a measuring component;

[0007] The measuring assembly comprises positioning rods arranged in an annular array in the oil storage tank, and a floating plate assembly is installed between the positioning rods in a sliding manner;

[0008] The floating plate assembly includes a floating plate body with positioning holes formed in a circular array inside, a liquid level measuring device is fixedly arranged in the middle of the floating plate body, the floating plate body is a funnel-shaped structure with the middle part smoothly collapsed downward, the positioning holes are slidably matched with the positioning support rods, and the inner wall structure of the positioning hole forms a drum surface portion with the middle part smoothly protruding toward the axis.

[0009] The utility model designs a floating plate body, which has a disc-shaped structure and can relatively fully fit the surface of the oil inside the oil storage tank, thereby increasing the contact area with the oil liquid surface. At the same time, the floating plate body is limited by the sliding cooperation of the positioning hole and the positioning support rod. When the oil storage tank is in the state of refueling or draining oil, the fluctuation amplitude of the liquid surface is reduced by increasing the contact area, thereby ensuring the accuracy of liquid level measurement and facilitating improving the real-time detection effect of liquid level information.

[0010] Preferably, a guide rod is formed in the center of the oil storage tank, a guide hole is opened in the center of the floating plate body, the liquid level measuring device is fixedly arranged in the guide hole, and the liquid level measuring device is installed in a sliding manner with the guide rod.

[0011] Preferably, the top end and the bottom end of the positioning support rod are fixedly connected to the bottom wall of the top cover and the bottom of the inner wall of the oil storage tank respectively.

[0012] Preferably, arc-shaped flow-guiding holes are formed in a circular array inside the floating plate body, and the arc-shaped flow-guiding holes are distributed in a vortex shape inside the floating plate body.

[0013] Preferably, an oil drain hole is formed at the bottom of one side of the oil storage tank, an oil drain pipe is integrally formed in the oil drain hole, and a refueling hole is formed inside the top cover, a refueling pipe is integrally formed in the refueling hole.

[0014] Preferably, a guardrail frame is fixedly provided at the top outer edge position of the top cover, a ladder is fixedly provided at one side of the oil storage tank, and a protective frame covering the outside of the ladder is fixedly provided at one side of the oil storage tank.

[0015] Preferably, the lower end surface of the floating platform body is provided with stabilizing rods in an annular array structure, and the end portions of the stabilizing rods are structured to form arc-shaped balancing rods.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model designs a floating plate body, which is a disc-shaped structure. It can relatively fully fit the surface of the oil inside the oil storage tank, thereby increasing the contact area with the oil surface. At the same time, the floating plate body is limited by the sliding cooperation of the positioning hole and the positioning support rod. When the oil storage tank is in the state of refueling or draining, the increase in the contact area is conducive to reducing the fluctuation amplitude of the liquid surface, thereby ensuring the accuracy of liquid level measurement, and is conducive to improving the real-time detection effect of liquid level information. It solves the problem that when the measuring structure is in use, when the oil tank is in the state of refueling or draining, the liquid surface fluctuation amplitude of the oil in the oil tank is large, affecting the accuracy of real-time detection of liquid level information.

[0018] 2. The utility model also forms a drum surface portion with a smooth protrusion in the middle toward the axis through the inner wall structure of the positioning hole. The drum surface structure of the drum surface portion is conducive to reducing the contact area between the positioning hole and the positioning support rod, thereby limiting the floating plate body through the sliding cooperation between the positioning hole and the positioning support rod, while improving the smoothness of the floating plate body rising and falling, avoiding the situation of getting stuck.
