Description

Technical Field

[0001] The invention relates to the technical field of heat pump units, and in particular to a photovoltaic direct-drive heat pump unit with optimized energy flow. Background Art

[0002] As an efficient energy conversion device, heat pump units play an important role in modern energy utilization. They use environmental or industrial waste heat as a low-temperature heat source and transfer heat to the high-temperature end through a thermodynamic cycle process for heating, cooling or hot water supply. Photovoltaic direct-drive heat pump units combine the advantages of photovoltaic power generation and heat pump technology to achieve efficient energy utilization and self-sufficiency.

[0003] However, the existing photovoltaic direct-drive heat pump units have some deficiencies in terms of maintenance. The units often contain some key maintenance components, such as filter screens, compressors, and photovoltaic panels. These components are installed in different locations of the unit due to their different functions. Therefore, when performing regular maintenance or replacing these wearing parts, the staff needs to go to the installation locations of each component to disassemble them. In addition, the compressor, as the core component of the heat pump unit, is usually installed inside the unit. Therefore, before maintaining the compressor, the outer casing of the unit must be removed first. This step increases the complexity and time-consuming of maintenance. In summary, the traditional heat pump unit's disassembly and installation methods for wearing parts are not only inefficient, but may also cause unnecessary damage to other components of the unit, increasing maintenance costs and downtime.

[0035] Please refer to Figures 1 to 8 :

[0036] Embodiment 1:

Through structural improvements, the heat pump unit only needs to drive the push rod 12 to open the protective sliding shell 16 for protecting the compressor unit, which is convenient for the staff to disassemble the compressor unit inside the heat pump unit. At the same time, the corresponding structure will also synchronously cancel the positioning of the filter cover 3 and the photovoltaic panel body 30, which is convenient for the staff to disassemble and replace these two components. The heat pump unit integrates the disassembly work of three functions and structural components with different installation positions, thereby improving the convenience of maintenance of the heat pump unit.

[0038] By starting the driving push rod 12, it controls the driving push block 13 and the driving push column 14 to move rightward, so that the driving push column 14 cooperates with the opening and closing inclined slot 17 to convert the rightward moving force into an upward force provided to the protective sliding shell 16, so that the protective sliding shell 16 cancels the protection of the compressor unit inside the heat pump body 1 by moving upward, making it easier for staff to access the compressor unit for maintenance.

[0039] Embodiment 2, on the basis of embodiment 1, an opening and closing inclined groove 17 is provided on both sides of the interior of the protective sliding shell 16; the opening and closing inclined groove 17 is an inclined structure; the driving push block 13 is also slidably installed inside the opening and closing inclined groove 17; a transmission slide 18 is fixedly installed on both sides of the front and rear of the protective sliding shell 16; the transmission slide 18 is an inverted structure; the top of the transmission slide 18 contacts the inclined surface of the force-bearing push groove 11; a top push fixing plate 19 is fixedly installed on the outer side of the transmission slide 18; a top push sliding column 20 is fixedly installed on the inner side of the top push fixing plate 19; the top push sliding column 20 is a cylindrical structure; a mounting bracket 21 is fixedly installed at the top position of the front and rear sides of the heat pump body 1; a support bracket 22 is fixedly installed on the outer side of the mounting bracket 21; and a limit baffle 23 is fixedly installed on the left and right sides of the support bracket 22; A positioning slot 24 is provided on the outer side of the upper limit baffle 23; the positioning slot 24 is an inclined structure; a guide slide post 25 is fixedly installed on the outer side of the support bracket 22; the guide slide post 25 is a cylindrical structure, and a plurality of structures cooperate to form a standby structure, through which the heat pump unit can be quickly placed in a standby state, and the standby state of the heat pump unit includes: canceling the positioning of the filter cover 3, opening the protective sliding shell 16 for protecting the compressor unit and canceling the positioning of the photovoltaic panel body 30, so that the staff can disassemble and replace or maintain the filter cover 3, the compressor unit and the photovoltaic panel body 30, which need regular maintenance. Compared with the separate disassembly of these components, it is more time-saving and labor-saving, saves maintenance time, and saves downtime of the heat pump unit;

[0040] When the protective sliding shell 16 moves upward, the protective sliding shell 16 will also move upward with the transmission slide 18. At this time, the top end of the transmission slide 18 will cancel the push on the inclined surface of the force-bearing push groove 11, so that the driven slide 7 and the limit insert 8 move outward under the action of the spring A10, so that the limit insert 8 is separated from the limit slot 5, thereby canceling the positioning of the filter cover 3, making it convenient for the staff to disassemble and maintain the filter cover 3.

[0041] Embodiment 3, on the basis of embodiment 2, a transmission slide plate 26 is slidably mounted on the guide slide column 25; the transmission slide plate 26 is an L-shaped structure; a spring B27 is embedded between the inner side surface of the transmission slide plate 26 and the outer wall of the support bracket 22; a positioning plug 28 is also provided on the inner front upper side of the transmission slide plate 26; the positioning plug 28 is an inclined structure; the positioning plug 28 corresponds horizontally to the position of the positioning slot 24; a transmission slide groove 29 is also provided on the transmission slide plate 26; the transmission slide groove 29 is composed of two vertical grooves and an inclined groove, and the bottom end of the lower vertical groove pierces the bottom of the transmission slide plate 26; the push slide column 20 is located below the lower vertical groove in the transmission slide groove 29; a photovoltaic panel body 30 is arranged on the support bracket 22; the photovoltaic panel body 30 is connected to the compressor unit and the fan unit in the heat pump body 1 through a line, and the optimized pipeline 15 for circulating liquid is made of tripropylene polypropylene. The inner wall of the pipeline of this material is smooth, which can reduce liquid resistance, increase liquid flow, and achieve energy flow optimization;

[0042] During the upward movement of the transmission slide 18, the push slide 20 on the transmission slide 18 will slide into the interior of the transmission slide groove 29, so that the push slide 20 cooperates with the inclined groove in the transmission slide groove 29 to convert the upward force into an outward force and provide it to the transmission slide 26, so that the transmission slide 26 moves outward with the positioning plug 28, so that the positioning plug 28 is disengaged from the interior of the positioning slot 24, thereby canceling the clamping of the photovoltaic panel body 30, making it easier for the staff to disassemble and maintain the photovoltaic panel body 30.

[0043] Working principle of this embodiment: When the components in the heat pump unit need to be maintained, it is only necessary to start the driving push rod 12, which will then control the driving push block 13 and the driving push column 14 to move to the right. In this process, the driving push column 14 and the opening and closing inclined slot 17 cooperate ingeniously to convert the rightward driving force into an upward force, which is transmitted to the protective sliding shell 16. The protective sliding shell 16 thus moves upward, releasing the protection state of the compressor unit inside the heat pump body 1, providing convenience for the staff to directly contact and maintain the compressor unit. At the same time, the protective sliding shell 16 also carries the transmission slide 18 to rise together during the rising process. This action causes the top of the transmission slide 18 to no longer push the inclined surface of the force-bearing push slot 11, so that the driven slide 7 and the limit insert 8 move outward under the elastic force of the spring A10. The limiting insert 8 then disengages from the limiting slot 5, releasing the positioning of the filter screen cover 3, so that the staff can easily disassemble and maintain the filter screen cover 3. In addition, during the rising process of the transmission slide 18, the push slide 20 thereon will slide into the transmission slide 29. The push slide 20 cooperates with the inclined groove in the transmission slide 29 to convert the rising force into an outward force and transmit it to the transmission slide 26. The transmission slide 26 therefore moves outward with the positioning insert 28, so that the positioning insert 28 is disengaged from the positioning slot 24, thereby canceling the clamping and fixing of the photovoltaic panel body 30, providing convenience for the staff to disassemble and maintain the photovoltaic panel body 30. After the maintenance or replacement of the parts is completed, only the driving push rod 12 needs to be reset, and the other structures will automatically recover under the action of their respective corresponding mechanisms. This includes restoring the positioning of the photovoltaic panel body 30 and the filter screen cover 3, and restoring the protective function of the protective sliding shell 16 on the compressor unit. The entire maintenance process is both efficient and convenient, greatly improving the maintainability and operating efficiency of the heat pump unit.
