Description

Technical Field

[0001] The invention relates to the field of vacuum heat collection tube sealing rubber ring auxiliary installation tools, in particular to a solar energy vacuum heat collection tube sealing rubber ring auxiliary installation tool and method under water operation. Background Art

[0002] According to the national energy strategic plan, solar energy, as a new type of renewable energy, has great development prospects. Due to its efficient heat absorption performance and low cost, solar vacuum collector tubes have been widely used in residential and industrial heating systems. However, such collector tubes usually need to be operated in a water environment during maintenance and replacement, which brings new challenges to the installation of sealing rubber rings. Existing installation tools usually cannot be operated in a water environment, and replacement and maintenance can only be performed after the water valve is closed or the water flow stops completely. This operation method brings a series of problems.

[0003] First, the need to close the water valve or drain the water in the pipe before operation leads to maintenance delays, affecting the continuity of the system's heating. Especially in winter or under continuous heating conditions, a heating system that cannot be repaired in time may reduce user comfort and may even cause more serious system failures. Secondly, the system needs to be refilled after draining, which not only wastes water resources but also increases maintenance costs. Therefore, the development of a solar vacuum collector tube sealing rubber ring auxiliary installation tool suitable for water environments can significantly improve maintenance efficiency, reduce heating interruptions, and save water resources.

[0004] This auxiliary tool can be used to replace the sealing rubber ring without interrupting the water supply, thus reducing the impact of maintenance on heating, achieving faster maintenance response, and improving user satisfaction. At the same time, it can also avoid unnecessary waste of water resources, conform to modern water-saving and environmental protection concepts, and have significant ecological and economic benefits. Therefore, the development of sealing rubber ring installation tools suitable for water-related working environments is of great significance to optimizing the maintenance process of solar collector tubes.

[0005] As a key component in solar water heaters, the solar sealing rubber ring not only prevents water leakage, but also maintains the thermal insulation effect and prevents foreign objects from entering the water tank. Since the water temperature inside the solar vacuum tube collector is usually between 40-60°C, special tools are indispensable for efficiently and safely replacing the sealing rubber ring and quickly restoring heating. In order to solve this problem, the present invention designs a water-blocking airbag, which is suitable for water-carrying operation scenarios such as water pipes of various diameters and solar vacuum collector tubes. When using this device, there is no need to shut off the water source or wait for drainage to replace the sealing rubber ring or perform other maintenance, which greatly improves work efficiency, reduces water waste, and ensures the continuous heating capacity of the system.

[0006] The installation tools currently available on the market include extended needle-nosed pliers, flathead screwdrivers, and tool sets designed specifically for installing solar seals. Professional solar water heater maintenance personnel sometimes make their own installation tools to meet specific needs. Existing tools have their own advantages and disadvantages in different scenarios, but they generally have the defects of complex manual operation, low installation accuracy, high risk of water leakage, and inconvenience in use and inability to work under water conditions. Furthermore, prior art tools may cause splashing injuries to operators during the installation of the seal, especially in extreme weather, which may further endanger personnel safety.

[0007] Technical solutions of the prior art

[0008] In the prior art, the installation of the sealing rubber ring of the solar water heater usually relies on manual operation, that is, the installer needs to manually place the sealing rubber ring in the joint gap between the vacuum tube and the header.

[0009] At the same time, the auxiliary tool, the extended needle-nose pliers, performs well in installations in narrow spaces or deep holes. The pointed design makes it easier to grab and manipulate small seals, and the extension provides sufficient leverage to improve the operator's force application conditions. The traditional flathead screwdriver is simple and easy to use when handling larger or tightly fixed seals, easy to carry, and is a standing tool for most families. There are tool sets designed specifically for the installation and maintenance of solar seals on the market. These sets include tool heads of different sizes and shapes to accommodate different seals and operating requirements. A set of multiple specifications can adapt to changing maintenance needs, and the dedicated design improves maintenance efficiency. Some professional solar water heater maintenance workers will make their own installation tools suitable for specific occasions based on their own experience and specific needs. Customized tools can perfectly fit the needs of specific jobs and improve maintenance efficiency and quality.

[0010] Disadvantages of existing technology

[0011] The manual installation method has many shortcomings. First, the manual installation process is cumbersome and requires a high level of technical skills from the installer. Second, due to the limited operating space and difficulty in visual identification, this method can easily lead to loose installation of the sealing rubber ring, posing a risk of water leakage. In addition, during the installation process, the operator is easily splashed with hot water, which may not only wet the clothes, but also cause damage to the skin, affecting the safety and comfort of the operation.

[0012] Extended needle-nose pliers may not be precise enough in some complex operations due to their length, and have limited compatibility with sealing rings of different sizes and shapes.

[0013] When installing a seal, a traditional slotted screwdriver may not be easy to insert into the seal because the head is too wide, and it may cause damage to the fragile seal material.

[0014] A tool kit specifically designed for solar seal installation and repair. The practicality and quality of the tool kit need to be verified. The price may be higher than ordinary tools.

[0015] Customized tools require certain DIY skills and tool-making knowledge, which makes them difficult to promote and use on a large scale.

[0016] Therefore, the above traditional installation methods seriously affect the installation efficiency and reliability of solar water heaters. There is an urgent need for a new method or tool that can simplify the installation process, improve installation accuracy and ensure the safety of installers, so as to improve the efficiency and reliability of the entire installation process.

[0017] The present invention aims to solve a series of problems currently faced by outdoor workers when replacing the sealing rubber rings of solar vacuum tubes. First, the installation process is cumbersome, resulting in low work efficiency. Secondly, due to the poor installation practicality, the operator may be at risk of being burned by hot water during the installation process. In addition, in extremely cold weather, wet clothes will also pose a potential threat to the operator's health. Finally, especially when there is water in the pipeline and it cannot be repaired in time in winter or in a continuous heating environment, the shutdown of the heating system will reduce the comfort of the users and may even cause more serious system failures.

[0086] Step S3: After the design is completed, the inflation scheme is tested and verified, and the inflation scheme is optimized and improved to improve performance and reliability.

[0087] When this embodiment is implemented, the present invention provides a sealing ring auxiliary installation tool, which is particularly suitable for the installation of silicone rings of solar collector tubes. Figure 1As shown, the sealing ring auxiliary installation tool is composed of an airbag, a positioning claw, a threaded tube, a connecting rod, a positioning ring, a movable disk, a threaded sleeve, a piston rod, etc. The overall structure is divided into two parts, the airbag water blocking part and the sealing ring installation part. First, the installation tool is installed in the hole, and the threaded tube drives the adjusting block to rotate by rotating the adjusting rod. The adjusting block drives the positioning claw to move inward or outward by a suitable distance through the connecting rod. Then, the silicone ring can be sleeved on the limiting ring, and the positioning claw is expanded again to make it fully contact with the inner wall of the silicone ring. The piston rod can be started to contract, so that it pulls the piston to move forward quickly, and the air in the cavity formed by the contact part between the adsorption head and the silicone ring is extracted. The silicone ring is tightly fitted on the limiting ring, thereby achieving the effect of fully controlling the volume of the silicone ring.

[0088] The tool comprises a positioning ring, the inner cavity of which is rotatably connected to a movable disk. The movable disk is designed with evenly distributed slide grooves, and a positioning claw is slidably connected to the slide groove. A limiting ring is provided at the rear of the positioning claw to fix the position of the silicone ring.

[0089] The mounting device further includes a threaded tube, and the adjusting block can be driven to rotate by rotating the threaded tube. The adjusting block is connected to the positioning claw through a connecting rod, so that the positioning claw can be moved inward or outward to a suitable distance. In this way, the user can easily place the silicone ring on the limit ring and expand the positioning claw again to make it fully contact with the inner wall of the silicone ring.

[0090] In order to ensure a tight fit between the silicone ring and the limiting ring, the device is also equipped with a piston. By pulling the piston, the air in the cavity formed by the contact between the adsorption head and the silicone ring can be extracted, thus forming a vacuum state, so that the silicone ring fits tightly on the limiting ring.

[0091] After completing the above steps, the user can retract the positioning claws by turning the threaded tube again. This will cause the silicone ring to sink toward the middle and reduce its volume, thereby achieving the purpose of safely and conveniently delivering the silicone ring into the collector tube hole and ensuring that the silicone ring effectively fits on the inner wall of the collector tube hole.

[0092] In addition, the design includes a water-blocking airbag at the end. By inflating, the water-blocking airbag can block the water inside to prevent hot water from hurting people, providing additional safety protection for users.

[0093] Water blocking scheme design: This scheme aims to ensure that during the installation of the solar vacuum collector tube sealing ring, a closed space is formed, which is crucial to prevent water and gas from escaping from the solar water heater system at the installation point. Such a closed environment ensures that the sealing ring can effectively perform its sealing function.

[0094] First, place the solar vacuum collector tube sealing ring correctly at the predetermined installation position, and make sure that the position and direction of the sealing ring are accurate. Then, place the water-blocking airbag around the sealing ring and inflate it to the appropriate pressure level to ensure that the airbag fits the sealing ring and the installation surface fully, thus forming an airtight closed space.

[0095] like Figure 2 As shown, the airbag is fixed to the mounting seat by means of hexagon socket screws. There are air holes on the lower surface of the airbag, and air can directly pass out from the middle mounting plate and then connect to the air cylinder outside the mounting tool through a hose.

[0096] Next, proceed to the actual installation steps of the sealing ring. This process needs to be carried out according to the specific structure and installation requirements of the solar water heater. Choose the appropriate installation method and tools, fix the sealing ring firmly in it, and check the installation position to ensure that the sealing ring has been correctly installed and can play its expected sealing role. After the installation of the sealing ring is completed, use it.

[0097] Finally, after confirming that the seal ring is installed correctly, remove the water blocking airbag from the installation location. At this time, it should be checked again to ensure that the seal ring can perform its sealing function normally, prevent any water and gas leakage, and ensure the normal operation and efficiency of the solar water heater system.

[0098] Design of sealing ring installation scheme: This scheme aims to ensure the stability and sealing effect of the sealing ring during installation. The size of the sealing ring is reduced by sucking the inner ring of the sealing ring with air pressure for installation, and the size of the sealing ring is enlarged and reduced by the rotation control of the connecting rod mechanism.

[0099] Specifically, the installation method includes the following steps: First, the operator rotates the adjustment rod so that the threaded tube drives the adjustment block to rotate. Then, the adjustment block drives the positioning claw to move inward or outward to a suitable distance through the connecting rod. Then, the operator can put the silicone ring on the limit ring and expand the positioning claw again to make it fully contact with the inner wall of the silicone ring.

[0100] like Figure 3 As shown, the movement of the threaded tube is restricted by the threaded sleeve. Specifically, when the threaded tube rotates, the threaded sleeve does not rotate with the threaded tube due to the specific joint design with the threaded sleeve. This mechanism effectively realizes the positioning function of the threaded tube. Furthermore, the threaded tube is designed as an internal hollow structure, so that the piston rod can reciprocate along the axial direction inside the threaded tube. This movement mechanism allows the system to perform inflation and deflation operations, thereby controlling the expansion and contraction of the sealing ring installed on the limit ring to adapt to different working conditions or achieve the adjustment of the sealing effect.

[0101] The positioning function of the threaded tube is effectively realized. Furthermore, the threaded tube is designed as an internal hollow structure, so that the piston rod can reciprocate along the axis direction inside the threaded tube. This movement mechanism allows the system to perform inflation and deflation operations, thereby controlling the expansion and contraction of the sealing ring installed on the limit ring to adapt to different working conditions or achieve the adjustment of the sealing effect.

[0102] Then, the telescopic rod can be retracted to pull the piston forward quickly. This action extracts the air in the cavity formed by the contact between the suction head and the silicone ring, so that the silicone ring fits tightly on the limit ring. This step achieves a full limit effect on the silicone ring.

[0103] By fitting the silicone ring tightly onto the limiting ring and adjusting the adjusting rod to shrink the positioning claw, the corresponding silicone ring is driven to be recessed toward the middle and reduce its volume. This mechanism ultimately achieves the effect of safely and conveniently inserting the silicone ring into the collector tube hole.

[0104] In summary, the solar water heater sealing ring auxiliary installation scheme of the present invention ensures the stability and sealing of the sealing ring during the installation process through precise mechanical control and air pressure regulation, improves installation efficiency, and reduces operational difficulty.

[0105] Inflation scheme design: This scheme aims to ensure that the gas can effectively drive the piston movement. Its core components include two structures that need to be inflated and deflated: the positioning claw suction and release structure and the air bag. The air hole on the positioning claw is made into a piston rod by the center of the threaded tube, and the piston rod is manually controlled to move forward and backward to achieve precise control of the positioning claw. In addition, the connection port and inflation pipeline between the air bag and the external air cylinder are designed to ensure safe and reliable connection and meet the inflation requirements of the air bag. After the design was completed, the inflation scheme was tested and verified, and the inflation scheme was optimized and improved to improve performance and reliability.

[0106] like Figure 4 The action of the piston rod is shown, with arrows showing its forward and backward movement. During the piston rod retraction phase, the air hole in the positioning claw shrinks the seal by suction, so that the movable disk can be inserted into the hole for positioning. Subsequently, the gas is released, allowing the seal to return to its original shape. When the piston rod is in the compressed state, the positioning claw exhausts the air, releasing the seal into the groove and fixing it in the groove by rotating the movable disk.

[0107] The air hole on the positioning claw is made into a piston rod by the center of the threaded tube, and the piston rod is manually controlled to move forward and backward. This design has been carefully considered and planned, including the structure, size, material and other aspects of the piston rod to ensure that it meets the expected functions and requirements. When selecting the materials of the various components of the piston rod, such as the piston, seals, etc., materials with sufficient strength, wear resistance and corrosion resistance should be selected. The selection of these materials is crucial to ensure the reliability and durability of the piston rod.

[0108] like Figure 5 As shown in the figure, the installation and positioning mechanism of the positioning claw is designed as a precise linkage system. The upper end of the positioning claw is connected to a connecting rod, and four connecting rods are synchronously connected to an adjustment block. This structure makes it possible for the four connecting rods to swing simultaneously when the threaded tube undergoes rotation, thereby driving the four positioning claws to move synchronously. This synchronous movement ensures the accuracy of positioning and the coordination of operation.

[0109] Furthermore, the lower end of each positioning claw is connected to a limit ring, which is designed with air holes, which are connected to corresponding interfaces on the mounting seat through hoses. The air holes on the mounting seat eventually lead to the center of the threaded tube. The design of this passage allows the system to be inflated and deflated by manually pushing the piston rod, thereby controlling the position adjustment of the positioning claw and the pressure change of the sealing ring on the limit ring to adapt to different working requirements or environmental conditions.

[0110] like Figure 6 As shown in the figure, the opening and closing of the positioning claw is achieved by rotating the threaded tube. When the user rotates the threaded tube in a clockwise direction, the adjustment block at the end of the threaded tube moves accordingly, and this movement causes the connecting rod connected to the adjustment block to rotate. The rotation of this connecting rod further pushes the positioning claw to move toward the outer ring, thereby smoothly sending the sealing ring into the preset groove.

[0111] On the contrary, when the user rotates the threaded tube counterclockwise, the adjustment block at the end of the threaded tube drives the connecting rod to rotate again, but at this time the movement of the connecting rod is to push the positioning claw toward the inner circle, causing the positioning claw to move inward and shrink the sealing ring, thereby releasing or adjusting the position of the sealing ring.

[0112] In this design, the interaction and precise mechanical coordination between the threaded tube, the adjustment block, the connecting rod, and the positioning claws ensure that the sealing ring can be accurately moved to the specified position and effectively contracted and released from the groove. This structure is not only easy to operate, but also can achieve fast and accurate position adjustment and installation or removal of the sealing ring, greatly improving the operating efficiency and flexibility of the equipment.

[0113] The specific design steps are as follows:

[0114] Step 1: Select the inner diameter size of the common type of sealing ring. The present invention takes the Φ47mm sealing ring as the design standard. The distance between the sealing ring and the entrance is about 100mm. The tool designed this time can move between 90-110mm to meet the installation requirements. The size of each part will be designed in order from large to small.
