TECHNICAL FIELD
[0001] The application relates to the technical field of battery sealing structures, in particular to a battery compartment sealing structure and an intelligent water meter. BACKGROUND
[0002] A sealing ring is usually used to seal the battery compartment of a water meter. When the sealing ring is placed in the battery compartment body, the sealing ring is extruded by a pressing block to produce elastic deformation. The deformation causes a certain contact force between the sealing ring and the inside of the compartment body, thereby forming a sealing barrier to prevent leakage. During the fastening process, the pressure on the sealing ring gradually increases, causing the sealing ring to deform further and increase the contact force with the compartment body, thereby improving the sealing performance. However, during actual installation, the sealing ring also bears frictional resistance from the pressing block in the axial direction, which can cause problems such as twisting and breaking, thereby affecting the service life. CONTENT OF THE UTILITY MODEL
[0003] The application aims to provide a battery compartment sealing structure and an intelligent water meter, which effectively ensure the sealing performance of the battery compartment and avoid the problem of leakage of the entire compartment body caused by deformation failure of a layer of sealing ring.
[0004] To achieve the above-mentioned purpose, the application adopts the following technical scheme:
[0005] On the one hand, a battery compartment sealing structure is provided, which comprises:
[0006] a compartment body, which has an accommodation space formed inside;
[0007] a sealing plug, which is installed in the accommodation space, and the outer peripheral surface of the sealing plug is provided with two sealing grooves, and the two sealing grooves are spaced apart along the axial direction;
[0008] two sealing rings, which are correspondingly installed in the two sealing grooves, and the outer wall surfaces of the two sealing rings are in contact with the inner wall surface of the accommodation space;
[0009] a locking assembly, which is installed on the upper side of the sealing plug, and the bottom of the locking assembly abuts against the sealing ring located above, thereby locking the position of the sealing plug in the accommodation space.
[0010] Further, the outer peripheral surface of the sealing plug is provided with a first flange and a second flange, and the first flange and the second flange form one of the sealing grooves, and the upper surface of the first flange forms the other sealing groove.
[0011] Further, a first gasket is arranged between the locking assembly and the sealing ring.
[0012] Further, an exhaust hole is formed in the sealing plug.
[0013] Further, a boss is arranged on the sealing plug, the exhaust hole is arranged at the center of the boss, and a screw plug is arranged on the boss to seal the exhaust hole.
[0014] Further, a second gasket is arranged between the screw plug and the boss.
[0015] Further, the locking assembly comprises a nut and a lead plug, the nut is arranged above the sealing plug and the bottom edge of the nut abuts against the sealing gasket arranged above, a mounting position is arranged at the center of the nut, and the lead plug is arranged in the mounting position.
[0016] Further, a limiting step is arranged inside the accommodating space to limit the mounting position of the sealing plug.
[0017] Further, a power supply element is arranged in the accommodating space, and a gap is arranged between the power supply element and the sealing plug.
[0018] In another aspect, the application further provides a smart water meter comprising the battery compartment sealing structure.
[0019] The battery compartment sealing structure has the following advantages: the core of the battery compartment sealing structure is the unique double-layer sealing design, two sealing grooves are arranged on the sealing plug and each sealing groove is provided with a sealing gasket, the outer wall surface of each sealing gasket is tightly attached to the inner wall surface of the ring groove to form two sealing lines, the double-layer sealing gasket design not only increases the level and redundancy of the sealing, but also significantly improves the reliability and safety of the sealing.
[0020] In particular, a gasket is specially designed on the top of the upper sealing gasket, the gasket plays a key buffering role in the tightening process of the locking assembly, effectively reducing the distortion of the upper sealing gasket caused by excessive pressure, which not only prolongs the service life of the upper sealing gasket, but also ensures the continuous stability of the sealing performance. At the same time, the lower sealing gasket cleverly avoids the friction force from the axial direction of the locking assembly. Since it is located below the upper sealing gasket and does not directly contact the locking assembly, its stress condition is much better than that of the upper sealing gasket. This design enables the lower sealing gasket to maintain its original elasticity and sealing performance, further enhancing the sealing effect of the battery compartment body.
[0021] In addition, since the sealing plug adopts a radial sealing mode, in order to ensure smooth exhaust during installation, an exhaust hole is carefully designed on the sealing plug, which not only provides a channel for gas exhaust during installation, but also ensures that the sealing plug can tightly attach to the inner wall of the compartment body after installation to form an effective seal.

DETAILED DESCRIPTION
[0030] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application are described in further detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0031] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0032] In the present application, unless specifically and expressly defined otherwise, "on" or "under" of a first feature to a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "over" of a first feature to a second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher than the second feature in horizontal height. "Under", "below" and "underneath" of a first feature to a second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower than the second feature in horizontal height.
[0033] As shown in the Figures 1-6 The present embodiment provides a battery compartment sealing structure, comprising: a compartment body 1, a sealing plug 2, two sealing rings 3 and a locking assembly 4, the inside of the compartment body 1 is formed with a containing space 101; the sealing plug 2 is installed in the containing space 101, the outer circumferential surface of the sealing plug 2 is provided with two sealing grooves 203, the two sealing grooves 203 are distributed along the axial direction; two sealing rings 3 are correspondingly installed in the two sealing grooves 203, the outer wall surface of the two sealing rings 3 is in contact sealing with the inner wall surface of the containing space 101; the locking assembly 4 is installed on the upper side of the sealing plug 2, the bottom of the locking assembly 4 abuts against the sealing ring 3 located above, thereby locking the position of the sealing plug 2 in the containing space 101.
[0034] Based on the above scheme, the structure is mainly composed of a warehouse body 1, a sealing plug 2, two sealing rings 3 and a locking assembly 4. The inside of the warehouse body 1 is carefully designed to have a containing space 101 for accommodating components such as batteries. This space needs strict sealing protection to prevent external environment from interfering with the internal components. The sealing plug 2, as the core component of this sealing structure, is cleverly installed in the containing space 101 of the warehouse body 1. Its outer peripheral surface is specially designed with two axially spaced sealing grooves 203, which provide perfect installation positions for the two sealing rings 3. Each sealing ring 3 is accurately installed in the corresponding sealing groove 203, with its outer wall surface tightly fitted to the inner wall surface of the ring groove, forming two sealing lines. This double-layer sealing ring 3 design not only greatly increases the level and redundancy of sealing, but also significantly improves the reliability and safety of sealing, providing double protection for the battery warehouse body 1. In particular, the lower sealing ring 3 is located below the upper sealing ring 3 and does not directly contact the locking assembly 4. This design makes the lower sealing ring 3 much better than the upper sealing ring 3 in terms of stress, as it avoids direct pressure and possible friction damage from the locking assembly 4. Therefore, the lower sealing ring 3 can better maintain its original elasticity and sealing performance, providing more durable and stable sealing effect for the battery warehouse body 1. The locking assembly 4 is installed on the upper side of the sealing plug 2, with its bottom tightly contacting the upper sealing ring 3, and the sealing plug 2 is firmly fixed in the containing space 101 by appropriate fastening force. This design not only ensures the stability of the sealing ring 3, but also provides great convenience for installation and disassembly.
[0035] Further, the outer peripheral surface of the sealing plug 2 is provided with a first flange 201 and a second flange 202, and a sealing groove 203 is formed between the first flange 201 and the second flange 202. The upper surface of the first flange 201 forms another sealing groove 203. The space between the first flange 201 and the second flange 202 constitutes the first sealing groove 203 for installing the first sealing ring 3, which tightly fits the inner wall of the warehouse body 1 to form the first sealing barrier. At the same time, the upper surface of the first flange 201 forms the second sealing groove 203 for installing the second sealing ring 3, which tightly contacts the inner wall of the warehouse body 1 to form the second sealing barrier. This double-layer sealing ring 3 design significantly increases the level and redundancy of sealing, ensuring that even if one of the sealing rings 3 performance declines, the other sealing ring 3 can continue to effectively seal, thereby greatly improving the overall sealing performance of the battery warehouse body 1.
[0036] In addition, the lower sealing ring 3 (the first sealing ring 3) is located below the upper sealing ring 3 (the second sealing ring 3) and does not directly contact the locking assembly 4. This design not only avoids direct pressure and friction damage of the locking assembly 4 to the lower sealing ring 3, but also makes the stress of the lower sealing ring 3 more uniform, so that the original elasticity and sealing performance of the lower sealing ring 3 can be better maintained. The flange structure not only provides a stable mounting position for the sealing ring 3, but also increases the contact area between the sealing plug 2 and the inner wall of the battery compartment 1, further improving the reliability and stability of the sealing.
[0037] Preferably, a first washer 5 is further arranged between the locking assembly 4 and the sealing ring 3. The first washer 5 acts as an additional buffer layer, which can effectively prevent the locking assembly 4 from generating excessive pressure on the sealing ring 3 during tightening, thereby avoiding deformation or damage of the sealing ring 3 due to excessive compression, so as to ensure that the sealing ring 3 maintains close contact with the inner wall of the battery compartment 1, further enhancing the sealing effect. Through the buffering effect of the first washer 5, the wear of the sealing ring 3 caused by uneven stress during long-term use can be reduced, the service life of the sealing ring 3 can be prolonged, and the maintenance cost caused by replacement of the sealing ring 3 can be reduced. In addition, the presence of the first washer 5 makes the contact between the locking assembly 4 and the sealing ring 3 smoother, reduces the friction resistance during installation and disassembly, and makes the operation more convenient. Moreover, the first washer 5 not only plays a buffering and protective role for the sealing ring 3, but also enhances the connection stability between the locking assembly 4 and the sealing plug 2, making the entire battery compartment sealing structure more stable and reliable.
[0038] In some embodiments, an exhaust hole 204 is further arranged on the sealing plug 2. The battery compartment may generate certain gas pressure inside during long-term operation or under certain conditions. The design of the exhaust hole 204 allows these gases to be automatically discharged when the pressure reaches a certain level, thereby avoiding safety hazards caused by excessive internal pressure of the battery compartment. This design helps to maintain the balance of the internal pressure of the battery compartment and ensures the normal operation of the battery compartment. Moreover, if the gas inside the battery compartment accumulates for a long time, it may adversely affect the performance and life of the battery. The exhaust hole 204 can timely discharge these gases to prevent them from accumulating inside the battery compartment, thereby protecting the battery from damage. In addition, if the gas inside the battery compartment cannot be discharged in time, it may cause serious safety accidents such as explosion. The design of the exhaust hole 204 can effectively reduce this risk and improve the safety of the battery compartment. Especially during high temperature or charging process, a large amount of gas may be generated inside the battery compartment. The presence of the exhaust hole 204 can ensure that these gases are discharged in time to avoid safety hazards.
[0039] Specifically, the sealing plug 2 is provided with a boss 205, the exhaust hole 204 is located at the center of the boss 205, and the boss 205 is provided with a screw plug 6 for sealing the exhaust hole 204. The exhaust hole 204 is located at the center of the boss 205, which can ensure that the gas accumulated in the battery compartment can be accurately and efficiently discharged through the exhaust hole 204 when it reaches a certain level. The existence of the boss 205 not only provides a clear positioning for the exhaust hole 204, but also makes the exhaust process more concentrated and controllable. The screw plug 6 as the sealing device of the exhaust hole 204 can be easily installed and removed. When exhaust is needed, the screw plug 6 can be simply unscrewed to allow gas to be discharged; when exhaust is not needed, the exhaust hole 204 can be sealed by tightening the screw plug 6 to prevent external gas or moisture from entering the battery compartment. This design allows the sealing performance of the battery compartment to be flexibly adjusted according to actual needs.
[0040] In addition, the screw plug 6 and the boss 205 are also provided with a second gasket 7. The second gasket 7 as an additional sealing layer can fill the small gap between the screw plug 6 and the boss 205, preventing gas or moisture from entering or leaking into the battery compartment. This design significantly improves the sealing performance of the battery compartment, ensuring its stability and safety in various working environments. The second gasket 7 is usually made of wear-resistant and corrosion-resistant materials, which can withstand the friction and pressure generated during the tightening and unscrewing of the screw plug 6. This design prolongs the service life of the screw plug 6 and the boss 205, reducing maintenance costs due to sealing failure. Moreover, the presence of the second gasket 7 makes the contact between the screw plug 6 and the boss 205 smoother, reducing the friction resistance during installation and removal. This not only makes the operation more convenient, but also reduces the risk of sealing failure due to improper operation.
[0041] In some embodiments, the locking assembly 4 includes a nut 401 and a lead seal 402. The nut 401 is installed above the sealing plug 2 and its bottom edge abuts the sealing ring 3 above. The center of the nut 401 is provided with a mounting position, and the lead seal 402 is arranged in the mounting position. The nut 401 serves as the main part of the locking assembly 4, and its bottom edge abuts the sealing ring 3 above to ensure that the sealing ring 3 can tightly fit the inner wall of the battery compartment 1 when subjected to pressure, forming an effective sealing barrier. The design of the nut 401 makes the installation and removal of the locking assembly 4 relatively simple and fast. The staff only needs to rotate the nut 401 to achieve locking or loosening, without the need for complex tools or steps. This design improves the convenience of maintenance and reduces the difficulty of operation. The lead seal 402 is a highlight of this design. It not only serves as a visual identifier after the nut 401 is installed, indicating that the battery compartment has been properly locked, but also prevents unauthorized removal. Once the lead seal 402 is damaged, it means that the battery compartment may have been opened or tampered with, which is of great significance to ensure the integrity and safety of the items in the battery compartment.
[0042] Generally, the inside of the containing space 101 is provided with a limiting step for limiting the installation position of the sealing plug 2. The limiting step provides a clear installation position and a fixed reference point for the sealing plug 2. During assembly, the sealing plug 2 can be easily aligned with the limiting step to ensure that the sealing plug 2 is correctly installed at the predetermined position. This design not only simplifies the installation process, but also improves the accuracy and reliability of the installation. The presence of the limiting step can effectively prevent the sealing plug 2 from being misaligned or loose during installation. Even under external force, the sealing plug 2 will remain in the correct position due to the blocking of the limiting step, thereby avoiding the problem of sealing failure caused by misalignment or looseness.
[0043] Optionally, the containing space 101 is also provided with a power supply 8, and a gap is left between the power supply 8 and the sealing plug 2. The power supply 8 (such as a battery and a capacitor) generates heat during operation. If the power supply 8 is in close contact with the sealing plug 2, the heat may be transmitted to other parts of the battery compartment through the sealing plug 2, which may even cause the sealing material to deform due to heat, affecting the sealing performance. Leaving a gap can prevent this from happening, ensuring that heat can be effectively dissipated to prevent heat accumulation from damaging the sealing plug 2 and the battery compartment.
[0044] It is worth mentioning that the assembly steps of the above battery compartment sealing structure are as follows: first, the power supply 8 needs to be smoothly put into the accommodating space 101 of the battery compartment along the axial direction, ensuring that the power supply 8 is correctly installed and avoiding damage or misplacement during installation. Second, the two sealing rings 3 are accurately installed in the sealing groove 203 of the sealing plug 2, ensuring that the sealing rings 3 are not twisted or damaged, and the correct installation of the sealing rings 3 is the key to forming an effective seal, which can prevent gas or moisture leakage. Then, the sealing plug 2 is placed in the accommodating space 101, and the bottom of the sealing plug 2 is tightly fitted with the limiting step, which provides an accurate installation position for the sealing plug 2, preventing misplacement or loosening of the sealing plug 2 during installation. The second gasket 7 is placed between the screw plug 6 and the boss 205, ensuring that the gasket is flat and not twisted, and the screw plug 6 is screwed into the boss 205, ensuring that the exhaust hole 204 is completely closed and the screw plug 6 is not loose. The second gasket 7 enhances the sealing performance between the screw plug 6 and the boss 205, improving the overall sealing effect, and the tight fit of the screw plug 6 can prevent gas leakage from the exhaust hole 204, while allowing exhaust when needed by unscrewing the screw plug 6. Finally, the nut 401 is tightened on the screw plug 6, ensuring that the nut 401 is tightly fitted with the boss 205, and then the lead seal 402 is installed to prevent unauthorized disassembly. The combination of the nut 401 and the lead seal 402 provides additional security to prevent the battery compartment from being opened or tampered with without authorization.
