Description

Technical Field

[0001] This utility model relates to the field of sealing performance testing technology, specifically a testing device for the sealing performance of alkaline battery sealant. Background Technology

[0002] Battery leakage is fatal for alkaline batteries. The causes of battery leakage are multifaceted, including mechanical reasons causing leakage at the seal, as well as physicochemical factors during the electrode process. There are various methods to prevent battery leakage. Using sealant to block the capillary channel between the inner wall of the battery's steel casing flare and the sealing ring is a very effective method, but it is still necessary to use testing equipment to test its sealing performance.

[0003] The prior art, disclosed in CN210893571U, provides a testing device for the sealing performance of alkaline battery sealant. The device includes a water storage device, a water pump, a first switching valve, a pressure gauge, and a sealed container, all connected in sequence. The sealed container mainly consists of a tank body and a lid. The upper edge of the tank body extends outward to form a circular protrusion. The lid body is mechanically fixed to the circular protrusion, and a ring of alkaline battery sealant is applied around the upper opening of the tank body on the contact surface between the lid body and the tank body. An exhaust port is located in the middle of the lid body above the tank body's cavity, and a second switching valve is located at the exhaust port. During operation, water is injected into the sealed container and pressurized by controlling the first switching valve, the second switching valve, and the water pump. When the pressure gauge pointer indicates the set pressure value, the first switching valve and the water pump are closed, and the container is left to stand. The pressure gauge pointer is observed to determine if there is any change during the standing period. If the pointer changes, the sealing performance of the alkaline battery sealant is poor; if the pointer remains unchanged, the sealing performance of the alkaline battery sealant is good.

[0004] The aforementioned patent primarily tests the sealing performance of a tank by adding water inside and using a pressure gauge. However, this method of testing the sealing performance involves delivering a large amount of water into the tank and using a pressure gauge to measure the sealing performance. This method can lead to a situation where, if the tank's seal is poor, the tank may not be fully filled with water, rendering the pressure gauge ineffective. Consequently, users cannot accurately test the sealing performance of the tank, reducing the accuracy of the alkaline battery sealant sealing performance testing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a testing device for the sealing performance of alkaline battery sealant, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a testing device for the sealing performance of alkaline battery sealant, comprising a device body, a detection component for gas content detection fixedly mounted on the top of the device body, a conveying component connected to one side of the device body, a component to be tested, a housing, a simulation container for simulating an alkaline battery placed inside the housing, a simulation cover fixedly mounted on the top of the simulation container, and sealant filled between the simulation container and the simulation cover. The conveying component is used to fill the simulation container with gas. The detection component includes a top cover fixedly mounted on the housing, and a gas detector for detecting the gas content inside the housing is installed through the top cover. The gas detector installed through the top cover allows for rapid testing of the sealant's sealing performance during use, improving the testing efficiency of the alkaline battery sealant sealing performance testing device.

[0007] Furthermore, an exhaust assembly for venting gas from the interior of the outer casing is fixedly installed on the top cover. Locking components are fixedly installed on both sides of the top cover, and these locking components are secured to the outer casing with bolts. This bolted installation of the locking components to the outer casing makes the internal structure of the alkaline battery sealant sealing performance testing device more robust and reliable, thus improving the operational safety of the device.

[0008] Furthermore, the gas outlet assembly includes a flow pipe that penetrates and is installed on the top cover. A second ball valve for controlling the gas flow within the flow pipe is fixedly installed on the flow pipe, and a filter element for gas filtration is fixedly installed at the top of the flow pipe. The filter element at the top of the flow pipe ensures that all gas emitted from the alkaline battery sealant sealing performance testing device is filtered and purified before being released, thus improving the environmental friendliness of the testing device.

[0009] Furthermore, the delivery assembly includes a gas tank for storing gas. A hollow first delivery pipe is fixedly installed on the side of the gas tank near the device body, and a first flange is fixedly installed on the end of the first delivery pipe away from the gas tank. The connection of the flange makes the internal components of the alkaline battery sealant sealing performance testing device more tightly connected, thereby improving the sealing performance of the alkaline battery sealant sealing performance testing device.

[0010] Furthermore, a second delivery pipe is fixedly installed on the side of the component under test near the delivery component. One end of the second delivery pipe is located inside the simulation tank, and a sealing gasket is filled between the outside of the second delivery pipe and the outer shell. A second flange is fixedly installed on the end of the second delivery pipe away from the simulation tank, and the second flange is sealed to the first flange. The sealed connection between the second flange and the first flange improves the sealing performance of the testing device for alkaline battery sealant.

[0011] Furthermore, a first ball valve for controlling the gas flow within the second delivery pipe is fixedly installed at its center, and a pressure gauge for detecting the gas filling level inside the simulation tank is fixedly installed on the second delivery pipe. This pressure gauge allows for the detection of whether the simulation tank is fully filled with gas, improving the practicality of the testing device for the sealing performance of alkaline battery sealant.

[0012] Furthermore, the gas tank contains carbon dioxide gas, and the gas detector is a carbon dioxide detector. The use of carbon dioxide gas in the gas tank and a carbon dioxide detector improves the convenience of testing the sealing performance of alkaline battery sealant within the testing device. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention simulates an alkaline battery as a canister and lid, fills the space between the canister and lid with sealant, fills the interior of the canister and lid with carbon dioxide gas, and finally uses a gas detector to detect the carbon dioxide content on the exterior of the canister and lid. This allows for the testing of the sealant's sealing performance. Even if gas leakage occurs at the beginning of the process, the leaked gas will be quickly detected by the gas detector, thus improving the accuracy of the alkaline battery sealant sealing performance testing device.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. Example

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application provides a further detailed description. A testing device for the sealing performance of an alkaline battery sealant includes a device body 2. A detection component 1 for detecting gas content is fixedly mounted on the top of the device body 2. A conveying component 3 is connected to one side of the device body 2. The device body 2 includes a component to be tested 21, which includes a housing 211. A simulation container 214 for simulating an alkaline battery is placed inside the housing 211. A simulation cover 212 is fixedly mounted on the top of the simulation container 214. Sealant 213 is filled between the simulation container 214 and the simulation cover 212. The conveying component 3 is used to supply sealant to the model. The simulated tank 214 is filled with gas. The detection assembly 1 includes a top cover 14 fixedly installed on the outer shell 211. A gas detector 11 for detecting the gas content inside the outer shell 211 is installed through the top cover 14. A gas outlet assembly 12 for venting the gas inside the outer shell 211 is also fixedly installed on the top cover 14. Locking members 13 are fixedly installed on both sides of the top cover 14. The locking members 13 are fixedly installed to the outer shell 211 by bolts. The gas outlet assembly 12 includes a flow pipe 123 that penetrates the top cover 14. A useful... A second ball valve 122 controls the gas flow within the flow pipe 123. A filter body 121 for gas filtration is fixedly installed at the top of the flow pipe 123. The conveying assembly 3 includes a gas tank 33 for storing gas. A hollow first conveying pipe 32 is fixedly installed on the side of the gas tank 33 near the device body 2. A first flange 31 is fixedly installed at the end of the first conveying pipe 32 away from the gas tank 33. A second conveying pipe 25 is fixedly installed on the side of the component under test 21 near the conveying assembly 3. One end of the second conveying pipe 25 is located inside the simulation tank 214. A sealing gasket 22 is filled between the outside of the delivery pipe 25 and the outer shell 211. A second flange 24 is fixedly installed at the end of the second delivery pipe 25 away from the simulation tank 214. The second flange 24 is sealed to the first flange 31. A first ball valve 26 for controlling the gas flow in the second delivery pipe 25 is fixedly installed at the center of the second delivery pipe 25. A pressure gauge 23 for detecting the gas filling degree inside the simulation tank 214 is fixedly installed on the second delivery pipe 25. The gas tank 33 contains carbon dioxide gas. The gas detector 11 is a carbon dioxide detector.

[0024] In this invention, the gas detector 11 controls an internal infrared lamp to emit infrared light of a fixed wavelength through a drive circuit. After absorption by the gas to be measured, the amplitude of the infrared light changes. The concentration of the gas to be measured is then calculated by detecting the change. The signal output by the sensing element is filtered, amplified, and converted by an ADC before being input to a microprocessor. The microprocessor system performs corresponding temperature and pressure compensation processing based on the collected temperature and pressure, and finally calculates the carbon dioxide concentration value to be measured and outputs it to the display device. Since the gas detector 11 in this invention is a commonly used model on the market, this invention is not described in detail.

[0025] When the first ball valve 26 is opened, the gas tank 33 can continuously supply carbon dioxide gas to the simulation tank 214 through the first delivery pipe 32 and the second delivery pipe 25. When the simulation tank 214 is full of carbon dioxide gas, the continuous input from the gas tank 33 will increase the pressure inside the simulation tank 214. At this time, the value of the pressure gauge 23 will change accordingly. The user can judge whether the simulation tank 214 is full of gas by observing the change in the value of the pressure gauge 23.

[0026] The gas detector 11 can start detecting the carbon dioxide content inside the outer shell 211 before the delivery component 3 is running. When the delivery component 3 delivers carbon dioxide into the simulation tank 214, the user can compare the value of the gas detector 11 with the initial value to test the sealing performance and mechanical properties of the sealant.

[0027] When the second ball valve 122 is opened, the carbon dioxide will continue to move upward. Therefore, the carbon dioxide will be filtered by the filter body 121 before being emitted into the atmosphere, which improves the environmental friendliness of the test device for the sealing performance of alkaline battery sealant.

[0028] The simulated can 214 and simulated cover 212 are made of the same material and are the same size as alkaline batteries, so that the data detected by the simulated can 214 and simulated cover 212 can achieve a similar effect to that of using alkaline batteries.

[0029] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the alkaline battery sealant sealing performance testing device are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. Before use, the user fills the sealant to be tested between the simulation cap 212 and the simulation tank 214. Both the second ball valve 122 and the first ball valve 26 are closed. The user observes the value displayed on the gas detector 11. Then, the user opens the first ball valve 26, and carbon dioxide gas from the gas tank 33 is continuously supplied to the simulation tank 214. When the value in the pressure gauge 23 gradually increases, it indicates that the simulation tank 214 is full of carbon dioxide gas. At this point, the user closes the first ball valve 26. After waiting for a period of time, the user observes the value displayed by the gas detector 11 again. If the value displayed by the gas detector 11 differs greatly from the initial value, it indicates that the sealing performance of the sealant is poor. If the value displayed by the gas detector 11 differs very little from the initial value, it indicates that the sealing performance of the sealant is good. When the gas inside the outer casing 211 needs to be released, the user opens the second ball valve 122. At this time, the gas will first be filtered through the filter body 121, and then meet the emission standards and be released into the atmosphere. Through the cooperation of the above components, even if gas leakage occurs in the canister at the beginning of the test, the leaked gas will be quickly detected by the gas detector, which improves the accuracy of the alkaline battery sealant sealing performance test device for sealant sealing performance testing.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
