Description

Technical Field

[0001] This utility model belongs to the technical field of water heaters, specifically relating to a solar flat-plate water heater with an easy-to-replace heat-absorbing plate. Background Technology

[0002] The basic structure of a solar flat-plate water heater typically includes: an outer frame, a transparent cover, a heat-absorbing plate assembly, and a back insulation layer. The transparent cover primarily serves to allow light to pass through and to retain heat; the heat-absorbing plate assembly is used to absorb solar energy.

[0003] In practical use, the heat absorber plate assembly may be at risk of coating aging or corrosion damage after long-term use, requiring regular maintenance or replacement. However, in the existing technology, the transparent cover is usually glued or directly fixed to the outer frame using a large number of screws and pressure strips. Disassembling the transparent cover before replacing the heat absorber plate requires a lot of time and is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a solar flat-plate water heater with an easy-to-replace heat-absorbing plate, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A solar flat-plate water heater with an easy-to-replace absorber panel includes a limiting component, a collector frame, a water pipe fixedly connected inside the collector frame, a cover frame rotatably connected to the top of the collector frame, a transparent cover plate fixedly connected inside the cover frame, an L-shaped plate on the right side of the collector frame that can constrain the cover frame by movement, a pressing component for pressing the cover frame on the outside of the collector frame, and a positioning component at the right end of the collector frame; auxiliary components include a bent plate fixedly connected to the outside of the collector frame, a lifting component on the outside of the collector frame, and a constraint component on the outside of the bent plate.

[0007] In a preferred embodiment of this utility model, the extrusion assembly includes a guide block fixedly connected to the outside of the collector frame, a guide plate slidably connected to the inner wall of the guide block, the guide plate being fixedly connected to an L-shaped plate, a handle being fixedly connected to the right side of the L-shaped plate, a support base being fixedly connected to the inner wall of the L-shaped plate, and a pressure roller being rotatably connected inside the support base.

[0008] As a preferred embodiment of this utility model, an inclined surface is provided at the top of the cover frame corresponding to the pressure roller, and the pressure roller is in contact with the inclined surface.

[0009] In a preferred embodiment of this utility model, the positioning component includes a stud fixedly connected to the right end of the collector frame, a threaded sleeve connected to the outside of the stud, a hexagonal block fixedly connected to the outside of the threaded sleeve, a rotatable ring rotatably connected to the outside of the threaded sleeve, a hanging rope fixedly connected to the outside of the rotatable ring, and the hanging rope being fixedly connected to the handle.

[0010] In a preferred embodiment of this utility model, a through hole is provided inside the L-shaped plate at the position corresponding to the stud, and the stud passes through the through hole.

[0011] In a preferred embodiment of this utility model, the lifting assembly includes a lifting rod slidably connected inside the guide plate. A first roller is provided at the bottom of the lifting rod, and the first roller contacts the bending plate. A second roller is provided at the top of the lifting rod, and the second roller contacts the cover frame. A limiting post is fixedly connected to the inner wall of the guide block, and the limiting post is slidably connected to the guide plate.

[0012] In a preferred embodiment of this utility model, the constraint assembly includes a housing fixedly connected to the bottom of the bending plate, a guide post fixedly connected to the inner wall of the housing, a lifting block slidably connected to the outside of the guide post, the lifting block being slidably connected to the bending plate, and the bottom of the lifting block being elastically connected to the housing via a spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. With the setting of limiting components, the collector frame and the cover frame are connected by rotation, which allows the transparent cover plate to be easily opened or closed, simplifying the process of replacing the heat absorption plate. By pushing the L-shaped plate with the handle, the pressure roller on it rolls and presses down along the inclined surface of the top of the cover frame. Then, by using the stud and threaded sleeve, the L-shaped plate can be quickly fixed, thus achieving a stable and reliable locking of the cover frame, ensuring the sealing and wind resistance of the collector during operation.

[0015] 2. With the help of the auxiliary components, when the L-shaped plate is pulled to the right to unlock, it will simultaneously drive the lifting rod to rise, and push the cover frame upward through the second roller at the top, thus providing initial assistance for opening the cover frame. This makes it convenient for staff to quickly pick up and rotate the cover frame. The spring is always based on the upward force of the lifting block, making it difficult for the first roller that has passed the lifting block to reset, thereby avoiding the L-shaped plate from swaying back and forth. This makes it easy for the cover frame to contact the second roller again when closing later, which facilitates simultaneous control of the movement of the L-shaped plate and the closing of the cover frame, avoiding the risk of pinching hands when manually closing the cover frame.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a solar flat-plate water heater with easy-to-replace absorber plate, including a limiting component, a collector frame 10, a water pipe 11 fixedly connected inside the collector frame 10, a cover frame 12 rotatably connected to the top of the collector frame 10, a sealing ring provided in the contact area between the top of the collector frame 10 and the cover frame 12, a transparent cover plate 13 fixedly connected inside the cover frame 12, an L-shaped plate 14 provided on the right side of the collector frame 10, the L-shaped plate 14 can constrain the cover frame 12 by moving, a pressing component 15 for pressing the cover frame 12 is provided outside the collector frame 10, and a positioning component 16 is provided at the right end of the collector frame 10.

[0030] The collector frame 10 serves as the main structure to support the heat absorption plate and the insulation layer. The cover frame 12 is opened and closed as a whole through a rotating connection to facilitate the replacement of the heat absorption plate. The sealing ring on its contact surface is used to ensure the sealing when closed. When it is necessary to replace the heat absorption plate, the constraint on the cover frame 12 is released and it is moved. Then the cover frame 12 can be rotated around the hinge to open, which facilitates the replacement of the heat absorption plate.

[0031] Furthermore, the extrusion assembly 15 includes a guide block 151 fixedly connected to the outside of the collector frame 10. A guide plate 152 is slidably connected to the inner wall of the guide block 151. The guide plate 152 is fixedly connected to the L-shaped plate 14. A handle 153 is fixedly connected to the right side of the L-shaped plate 14. A support seat 154 is fixedly connected to the inner wall of the L-shaped plate 14. A pressure roller 155 is rotatably connected inside the support seat 154. When locking the cover frame 12, the L-shaped plate 14 is pushed to the left by the handle 153, causing it to slide along the guide block 151, which drives the pressure roller 155 to roll and press down along the inclined surface of the cover frame 12. When opening, the handle 153 is pulled to the right, causing the pressure roller 155 to leave the inclined surface and release the pressure, facilitating the rotation of the cover frame 12.

[0032] The top of the cover frame 12 is provided with an inclined surface at the position corresponding to the pressure roller 155, and the pressure roller 155 contacts the inclined surface. The inclined surface on the cover frame 12 is used to cooperate with the pressure roller 155 to convert the horizontal thrust transmitted from the L-shaped plate 14 into a vertical downward pressure, thereby forcing the cover frame 12 to be tightly pressed against the sealing ring of the collector frame 10 to achieve a seal.

[0033] Furthermore, the positioning component 16 includes a stud 161 fixedly connected to the right end of the collector frame 10. A threaded sleeve 162 is threadedly connected to the outside of the stud 161. A hexagonal block 163 is fixedly connected to the outside of the threaded sleeve 162. A swivel ring 164 is rotatably connected to the outside of the threaded sleeve 162. A hanging rope 165 is fixedly connected to the outside of the swivel ring 164. The hanging rope 165 is fixedly connected to the handle 153. The hanging rope 165 connects the threaded sleeve 162 to the handle 153. Its main function is to prevent the threaded sleeve 162 from being lost or falling off when not in use. When the L-shaped plate 14 moves to the right end locking position, the threaded sleeve 162 is rotated to move to the left along the stud 161, using the self-locking characteristic of the thread to prevent the L-shaped plate 14 from accidentally moving back. When unlocking, the threaded sleeve 162 is rotated in the opposite direction to release the pressure on the L-shaped plate 14.

[0034] It should be noted that the L-shaped plate 14 has a through hole at the position corresponding to the stud 161, and the stud 161 passes through the through hole. The main function of the through hole on the L-shaped plate 14 is to provide a passage for the stud 161 to pass through, ensuring that the stud 161 can pass through accurately and cooperate with the threaded sleeve 162, which facilitates the limiting operation of the L-shaped plate 14.

[0035] During use, after the absorber plate is replaced, the operator rotates the cover frame 12 around its hinge point with the collector frame 10 until it is flat. Then, the operator pushes the handle 153 to the left, causing the L-shaped plate 14 to move to the left along the collector frame 10. The pressure roller 155 fixed on the L-shaped plate 14 moves accordingly and contacts the inclined surface at the top of the cover frame 12. This inclined surface structure converts the horizontal thrust into downward pressure, making the sealing ring at the top of the collector frame 10 fit tightly against the cover frame 12. As the L-shaped plate 14 moves to the left... The stud 161 passes through the through hole inside the L-shaped plate 14. By rotating the threaded sleeve 162, it is threaded onto the outside of the stud 161, thereby limiting the L-shaped plate 14 and ensuring its stability. When opening, the threaded sleeve 162 is loosened in the opposite direction to move it away from the stud 161. With the help of the hanging rope 165, the threaded sleeve 162 is prevented from falling off. Then, the handle 153 is pulled to the right to release the clamping force, allowing the cover frame 12 to be opened freely for easy replacement of the heat absorption plate.

[0036] Example 2

[0037] Reference Figures 6-9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides auxiliary components, including a bent plate 20 fixedly connected to the outside of the collector frame 10, a lifting component 21 provided on the outside of the collector frame 10, and a restraining component 22 provided on the outside of the bent plate 20.

[0038] Specifically, the bending plate 20 provides an installation base for the auxiliary components, and its specific contour is used to guide the movement trajectory of the lifting assembly 21, while the constraint assembly 22 ensures that the lifting assembly 21 can be stably maintained after moving to a specific position.

[0039] Furthermore, the lifting assembly 21 includes a lifting rod 211 slidably connected inside the guide plate 152. A first roller 212 is provided at the bottom of the lifting rod 211, contacting the bending plate 20. A second roller 213 is provided at the top of the lifting rod 211, contacting the cover frame 12. A limiting post 214 is fixedly connected to the inner wall of the guide block 151, and the limiting post 214 is slidably connected to the guide plate 152. The first roller 212 engages with the inclined profile of the bending plate 20, converting the horizontal movement of the guide plate 152 into the vertical lifting movement of the lifting rod 211. The second roller 213 at the top transmits the lifting movement to the cover frame 12 to provide lifting assistance, facilitating subsequent rotation of the cover frame 12 by the user.

[0040] Furthermore, the constraint component 22 includes a housing 221 fixedly connected to the bottom of the bending plate 20. A guide post 222 is fixedly connected to the inner wall of the housing 221. A lifting block 223 is slidably connected to the outside of the guide post 222. The lifting block 223 is slidably connected to the bending plate 20. The bottom of the lifting block 223 is elastically connected to the housing 221 through a spring 224. During the operation of the lifting component 21, the first roller 212 squeezes and passes over the lifting block 223. The lifting block 223 quickly resets and rises under the action of the spring 224, forming a limit, so that the second roller 213 and the L-shaped plate 14 are not prone to accidental movement, and the cover frame 12 can contact the second roller 213 again when it is closed later.

[0041] In use, when the handle 153 is pulled to the right to unlock, the movement of the L-shaped plate 14 causes the guide plate 152 fixed to it to move to the right in sync. The lifting rod 211, which is fixed to the guide plate 152, moves accordingly. The first roller 212 at its bottom rolls on the inclined surface of the bent plate 20 fixed to the collector frame 10, forcing the lifting rod 211 to move upward. The second roller 213 at the top pushes up the edge of the cover frame 12, providing assistance and an initial angle for opening. During this process, the lifting block 223 springs... Under the thrust of spring 224, the bending plate 20 is always extended. When the first roller 212 squeezes and passes over the lifting block 223, the guide plate 152 moves to the maximum distance. The elastic force of spring 224 will prevent the lifting block 223 from falling back, thereby preventing the guide plate 152 and the L-shaped plate 14 connected to it from accidentally moving to the left and resetting. This makes it easier for the cover frame 12 to contact the second roller 213 again when it is closed later. It is convenient to control the leftward movement of the L-shaped plate 14 and the closing of the cover frame 12 at the same time, avoiding the risk of pinching hands when manually closing the cover frame 12.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
