Abstract
Description
Technical Field
[0001] This utility model relates to the field of product testing tools, and more specifically, to a partitioned multifunctional oil tank for product testing. Background Technology
[0002] In industrial production, performance testing after product overhaul (such as air tightness test, flow resistance test, and high temperature test) is a key link in ensuring product quality. As a core testing device, the performance of the oil tank directly affects the testing efficiency, accuracy, and space utilization.
[0003] In existing technologies, traditional product testing oil tanks are generally single-function and have low space utilization: most oil tanks are single-tank designs and can only complete one type of test (such as only airtightness test or only high temperature test), which requires enterprises to configure multiple devices, which not only increases procurement costs and energy consumption, but also occupies a lot of space. Especially in space-constrained testing environments, the problem of chaotic equipment layout is prominent.
[0004] Some oil tanks use a nested design to integrate functions, but the nested tanks lack a levelness detection mechanism. For example, if the shallow tank used for flow resistance testing is tilted, it will cause abnormal fluid flow and directly affect the accuracy of the flow resistance test data. At the same time, the gaps along the edges of the nested tanks are not sealed enough, which can easily lead to the mixing of fluid media from different tests (such as oil from the flow resistance test seeping into the water from the airtightness test), interfering with the test results.
[0005] In addition, the oil tanks used for high-temperature tests often rely on direct heating by bottom electric heating rods. Due to the slow natural convection speed of the fluid, the temperature distribution inside the tank is uneven, resulting in inconsistent heating of the products and low test accuracy. Furthermore, the heating area is large and the temperature rises slowly. Utility Model Content
[0006] The purpose of this application is to provide a partitioned, multi-functional oil tank for product testing, which solves the technical problems of existing product testing oil tanks having single function, low space utilization, low testing accuracy, and insufficient heating uniformity and efficiency.
[0007] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:
[0008] A partitioned, multi-functional oil tank for product testing includes a platform.
[0009] Preferably, the platform is installed horizontally, and an oil tank and a heating oil tank are movably nested on the platform, with an oil tank 2 movably nested on the oil tank.
[0010] Preferably, the heating oil tank includes an electric heating rod, and a heat equalization structure is also provided in the heating oil tank.
[0011] Preferably, the second oil tank is shallower than the first oil tank and the heating oil tank.
[0012] Preferably, a horizontal detection component is provided between the two groove edges of the oil tank one and the oil tank two.
[0013] Preferably, a sealing component is also provided between the groove edges of the first oil tank and the second oil tank.
[0014] Preferably, the volume and depth of the first oil tank are larger than those of the second oil tank and the heating oil tank.
[0015] Preferably, the bottom of the oil tank is connected to an oil drain valve.
[0016] Preferably, the heating oil tank includes oil tank three.
[0017] Preferably, the oil tank three is nested on the platform, and a row of electric heating rods is fixed at the bottom of the oil tank three. The electric heating rods are connected to an external power source, and a temperature sensor is installed inside the oil tank three. The temperature sensor is connected to an external display terminal.
[0018] Preferably, the bottom of the oil tank three is connected to an oil drain valve two.
[0019] Preferably, the level detection component includes a contact sensor and a sensing sheet.
[0020] Preferably, four contact sensors are vertically fixedly installed at the four corners of the groove edge of the second oil tank, and the sensing heads of the contact sensors are located below the groove edge of the second oil tank.
[0021] Preferably, four sensing plates are fixedly arranged at the four corners of the groove edge of the oil tank, and the sensing plates are located on the top surface of the groove edge of the oil tank and vertically correspond to the sensing head of the contact sensor.
[0022] Preferably, the sealing components are respectively disposed on the upper surface of the groove edge of oil tank one and the lower surface of the groove edge of oil tank two.
[0023] Preferably, the sealing assembly includes an annular magnet.
[0024] Preferably, a ring magnet is fixedly provided on the upper surface of the groove edge of oil tank one and the lower surface of the groove edge of oil tank two.
[0025] Preferably, the sealing assembly further includes a sealing strip, and each ring magnet is wrapped with a layer of sealing strip.
[0026] Preferably, the heat dissipation structure includes a mesh plate.
[0027] Preferably, a mesh plate is fixedly installed inside the oil tank three, the mesh plate is located above the electric heating rod, and the mesh plate has several through holes.
[0028] Preferably, the heat dissipation structure further includes a heat-conducting sheet and an air cavity.
[0029] Preferably, a plurality of heat-conducting sheets are vertically and slidably arranged on the mesh plate, and the plurality of heat-conducting sheets are evenly arranged, with air chambers provided at both the upper and lower ends of the heat-conducting sheets.
[0030] Preferably, the volume of the air cavity is larger than the sliding channel of the mesh plate.
[0031] The technical solution of this application has at least the following advantages and beneficial effects:
[0032] This invention integrates three functions—air tightness testing (oil tank one), flow resistance testing (oil tank two), and temperature testing (oil tank three)—on a single platform through a partitioned nested structure of multiple oil tanks with different functions. Oil tank two is nested vertically with oil tank one, while oil tank three is nested independently on the platform, reducing the equipment's footprint.
[0033] This invention utilizes a horizontal detection component (contact sensor + sensing plate) to monitor the nesting level of the second oil tank in real time, and uses indicator lights to feedback the tilt status, thus avoiding deviations in flow resistance test data caused by the tilt of the second oil tank and ensuring the accuracy of the flow resistance test. Furthermore, a sealing component (ring magnet + sealing strip) enhances nesting stability through magnetic positioning, preventing tank shaking caused by fluid flow during the flow resistance test. Simultaneously, the sealing strip seals the gaps along the tank edge, effectively preventing fluid from the second oil tank from seeping into the first oil tank, avoiding interference from the mixing of different test media, and ensuring the accuracy of the test results.
[0034] This invention achieves rapid and uniform heating by setting up a uniform heating structure (mesh plate + heat-conducting plate + air cavity) in the heating oil tank: the mesh plate isolates the product from the electric heating rod, avoiding direct contact damage; the heat-conducting plate floats in the fluid with the help of the air cavity buoyancy, quickly transferring the heat from the bottom to the upper part of the tank, so that the temperature in the tank rises evenly and rapidly; at the same time, the total volume of the oil tank is smaller than that of traditional heating tanks, reducing the total amount of heating medium and further accelerating the heating rate.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0046] Example 1
[0047] Please refer to Figures 1-8This utility model provides a partitioned multifunctional product testing oil tank, including a platform 1 for installing each oil tank. The platform 1 is installed horizontally, and an oil tank 2 and a heating oil tank 4 are nested on the platform 1. Furthermore, an oil tank 3 is nested on the oil tank 2.
[0048] Oil tank 2 and heating oil tank 4 are both movably mounted on platform 1 (their groove edges abut against the top surface of platform 1 to support the weight of each oil tank). The groove edge of oil tank 3 is also movably mounted on the groove edge of oil tank 2. A handle is also provided on the top groove edge, which can be used to quickly remove oil tank 2, oil tank 3 and heating oil tank 4 from platform 1.
[0049] Among them, oil tank 2 has the largest and deepest volume and can be used to store clean water for product airtightness testing.
[0050] Specifically, during the airtightness test of the product, the inner tank of oil tank 2 (nested within oil tank 2) is manually lifted and separated, exposing the inner tank of oil tank 2. Water is then added, and the product to be tested is placed in the water and completely submerged. The airtightness is then assessed by observing the bubbles. Oil tank 2 is also connected to a drain valve 21 at its bottom. During the test, the drain valve 21 is closed; after the test, the product is removed, and the drain valve 21 is opened to quickly drain the water.
[0051] Among them, oil tank 2, 3 has the shallowest tank depth, which can be used for product flow resistance testing.
[0052] Specifically, when conducting flow resistance testing on a product, the oil tank 2 3 is manually nested at the top edge of the oil tank 1 2. The product to be tested is placed inside the oil tank 2 3. Then, a flowing fluid medium is introduced from one side of the oil tank 2 3 using an external pump pipe, and a fluid medium is simultaneously pumped from the other side using an external pump suction pipe to ensure continuous flow of the fluid medium in the oil tank 2 3, thereby achieving the flow resistance test of the product.
[0053] The heating oil tank 4 includes an oil tank 3 41, an electric heating rod 42, an oil drain valve 2 43, a temperature sensor 44, and a heat equalization structure 7, which can be used to quickly and evenly heat the tank body for product temperature testing.
[0054] Specifically, oil tank 3 41 is nested on platform 1. A row of electric heating rods 42 is fixed at the bottom of oil tank 3 41. The electric heating rods 42 are connected to an external power source. A temperature sensor 44 is also fixedly installed inside oil tank 3 41. The temperature sensor 44 is electrically connected to an external display terminal to display the temperature value.
[0055] Specifically, during product temperature testing, a fluid medium is added to the oil tank 41, the product to be tested is placed inside, and then an electric heating rod 42 heats the fluid medium to the test temperature. The temperature is detected by a temperature sensor 44, and the heat equalization structure 7 inside the tank quickly and evenly transfers the temperature to the fluid medium, allowing it to reach the test temperature rapidly and improving product testing efficiency. The bottom of the oil tank 41 is also connected to an oil drain valve 43, which allows the fluid medium to be drained after the test.
[0056] Preferably, the three oil tanks can be divided into sections to conduct different functional tests on the product under test, achieving multifunctional testing results. Moreover, by nesting oil tank 1 and oil tank 2, installation space is further saved, and the space utilization of the test room is improved while ensuring that flow resistance test, sealing test and temperature test can be completed.
[0057] Furthermore, since the flow resistance test of the product needs to be performed on oil tank 2 3, the angle of the surface of oil tank 2 3 will also affect the flow resistance effect. Especially when oil tank 2 3 is nested in oil tank 1 2, when oil tank 2 3 is nested at an angle, the flow resistance effect of the fluid medium will change due to the inclination of the surface of oil tank 2 3, making it impossible to accurately perform the flow resistance test of the product.
[0058] Therefore, a level detection component 5 is provided between the two groove edges of oil tank 1 2 and oil tank 2 3 to detect the levelness of oil tank 2 3 when nested.
[0059] Specifically, the horizontal detection component 5 includes a contact sensor 51 and a sensing sheet 52.
[0060] Four contact sensors 51 are vertically fixed at the four corners of the groove edge of oil tank 2 3, and the sensing head of the contact sensor 51 is located below the groove edge of oil tank 2 3; four sensing plates 52 are correspondingly fixed at the four corners of the groove edge of oil tank 1 2, and the sensing plates 52 are located on the top surface of the groove edge of oil tank 1 2, and are vertically corresponding to the sensing head of the contact sensor 51.
[0061] When oil tank 2 (3) is nested on oil tank 1 (2), the four contact sensors 51 will approach and contact the sensing plate 52, thus simultaneously emitting four sensing signals. However, if oil tank 2 (3) is tilted during nesting, at least one contact sensor 51 will fail to contact the sensing plate 52, resulting in a maximum of three sensing signals being emitted simultaneously. The contact sensors 51 are electrically connected to the controller, which is in turn electrically connected to the indicator light. When oil tank 2 (3) is horizontally nested on oil tank 1 (2), the controller receives four signals from the contact sensors 51 and controls the indicator light to emit normal light. When oil tank 2 (3) is tilted and nested on oil tank 2 (3), the controller receives a maximum of three signals from the contact sensors 51 and controls the indicator light to emit a warning light, thus alerting the staff.
[0062] Furthermore, because each oil tank performs different types of tests on the products, the type of fluid medium used in the oil tank will also be different. When oil tank 1 2 and oil tank 2 3 are nested, especially when the shallow oil tank 2 3 is used for flow resistance testing (the fluid medium has strong fluidity), the fluid medium flowing in oil tank 2 3 is prone to splashing out and flowing into oil tank 1 2 through the gaps along the grooves of oil tank 1 2 and oil tank 2 3, affecting the subsequent product testing in oil tank 1 2.
[0063] Therefore, a sealing component 6 is also provided between the groove edges of oil groove 1 2 and oil groove 2 3. The sealing component 6 includes an annular magnet 61 and a sealing strip 62.
[0064] Specifically, the sealing components 6 are respectively installed on the upper surface of the groove edge of oil tank 1 2 and the lower surface of the groove edge of oil tank 2 3.
[0065] Specifically, a ring magnet 61 is fixedly installed on the upper surface of the groove edge of oil tank 1 2 and the lower surface of the groove edge of oil tank 2 3. Each ring magnet 61 is wrapped with a layer of sealing strip 62. When oil tank 2 3 is nested into oil tank 1 2, the ring magnets 61 on the groove edges of the two oil tanks will be magnetically attracted together quickly. This not only assists in the nesting and positioning of oil tank 2 3, but also improves the installation stability of oil tank 2 3 during flow resistance testing (flow resistance testing will generate force). In addition, after the two ring magnets 61 are magnetically attracted together, the two layers of sealing strip 62 on their surfaces will be squeezed together by their own elasticity, thereby sealing the groove edge gaps and reducing the possibility of test fluid mixing between the two nested oil tanks.
[0066] Furthermore, in order to achieve a uniform heat conduction effect in the heating oil tank 4, the uniform heat conduction structure 7 includes a mesh plate 71, a heat conduction sheet 72, and an air cavity 73.
[0067] Specifically, a mesh plate 71 is fixedly installed inside the oil tank 3 41. The mesh plate 71 is located above the electric heating rod 42, and several mesh holes are passed through the mesh plate 71. When the product temperature is tested, the mesh plate 71 can isolate the product from the electric heating rod 42 of the tank, avoid the product from contacting the electric heating rod 42 and causing damage, and ensure the flow of fluid medium in the tank (refer to oil grate).
[0068] In addition, to achieve uniform heat distribution during product temperature testing within the oil tank 41, several heat-conducting plates 72 are vertically and slidably installed on the mesh plate 71. These heat-conducting plates 72 are evenly distributed, and air cavities 73 are provided at both the upper and lower ends of each heat-conducting plate 72. When a fluid medium is added to the oil tank 41, the heat-conducting plates 72, due to the buoyancy of the air cavities 73, will overcome gravity and float upwards. This causes the heat-conducting plates 72, initially located at the lower part of the tank, to slide into the space above the mesh plate 71. When the electric heating rod 42 heats the fluid medium at the bottom of the tank, the temperature at the bottom of the tank is conducted to the fluid medium in the upper part of the tank through the floating heat-conducting plates 72, achieving uniform and rapid heating of the entire tank space. The volume of the air cavities 73 is larger than the sliding channel of the mesh plate 71, preventing the lower ends of the heat-conducting plates 72 from protruding beyond the mesh plate 71 due to buoyancy.
[0069] Preferably, in order to avoid the heat-conducting sheet 72 interfering with the placement of the product, the heat-conducting sheet 72 is set as a vertical floating structure. When the product is placed in the oil tank 3 41, the weight of the product will press part of the heat-conducting sheet 72 down, so that the product sinks to the vicinity of the mesh plate 71 in the tank, so that the product is located in the middle of the tank and can be submerged by the fluid medium, thus ensuring the temperature test effect of the product.
[0070] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
