TECHNICAL FIELD

[0001] The utility model belongs to the technical field of heating unit, specifically relates to a solar energy combines with the heating unit of ground source heat pump. BACKGROUND

[0002] With the popularization and application of renewable energy, the combination of solar energy and ground source heat pump technology in the heating field has gradually become a hot spot. The traditional heating unit runs through a single energy form, which is difficult to meet the needs of high efficiency and stable heating. The technical scheme of solar energy combined with ground source heat pump can effectively reduce the dependence on traditional fossil fuels and improve the economy and environmental protection of heating by using the clean energy of solar energy and the stable energy supply characteristics of ground source heat pump. However, in the prior art, there are some problems that need to be further optimized.

[0003] For example, the published patent document CN219177797U proposes a solar photovoltaic water ground source heat pump heating unit, which can realize heating by combining solar energy and ground source heat pump, but there is room for improvement in the cable fixation and protection of the equipment. The fixing device of the traditional cable is usually designed simply, which can only provide basic clamping and fixing function, and is easy to loosen during use, which leads to loose cable connection and affects the overall stability and safety of the equipment. In addition, the fixing device designed by part is not convenient to install and operate, which increases the complexity of equipment maintenance. UTILITY MODEL CONTENT

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a heating unit of solar energy combined with ground source heat pump, which can realize not only the safety and stability of the heating unit, but also the optimization of the operation process of cable installation.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0006] A heating unit of solar energy combined with ground source heat pump, comprising a body, a photovoltaic panel is arranged at the top of the body, a bracket is arranged between one end of the photovoltaic panel and the body, a clamping device is arranged on the side of the body, the clamping device comprises an inner lining plate inside the body and a sleeve outside the body;

[0007] The inner lining plate and the sleeve are connected by screws;

[0008] An observation window is provided on the sleeve;

[0009] The outer side of the two open ends of the sleeve is fixedly connected with a locking plate and a locking head respectively;

[0010] A driving assembly is connected to the locking plate and the locking head;

[0011] The driving assembly comprises a threaded column penetrating through the locking plate and the locking head, and a nut is connected to one end of the threaded column;

[0012] The threaded column can shorten the distance between the locking plate and the locking head.

[0013] Further, a clamping member is sleeved on the threaded column, and the clamping member is clamped on the locking head;

[0014] One end of the threaded column is fixedly connected with a handle.

[0015] Further, a pin joint member is sleeved on the threaded column, the pin joint member is located in the locking head, and a locking handle is rotatably connected to the pin joint member;

[0016] The locking handle can be further pressed downward to shorten the distance between the locking plate and the locking head.

[0017] Further, a third through hole is formed through the center of the side surface of the pin joint member, and the threaded column passes through the third through hole;

[0018] Pin joint holes are formed through the two side surfaces of the pin joint member;

[0019] One end of the locking handle is fixedly connected with a pin joint plate, and the pin joint plate is rotatably connected to the pin joint hole.

[0020] Further, the other end of the locking handle is fixedly connected with a pressing head.

[0021] Further, a first through hole is formed through the center of the side surface of the inner lining plate;

[0022] One end of the sleeve is fixedly connected with a connecting plate, and a second through hole corresponding to the first through hole is formed through the center of the side surface of the connecting plate.

[0023] Further, connecting holes are formed through the side surface of the inner lining plate in a symmetrical manner, and screw holes corresponding to the connecting holes are formed through the side surface of the connecting plate.

[0024] Compared with the prior art, the utility model has the advantages that:

[0025] The solar energy combined with the ground source heat pump heating unit can effectively solve the problem of insecure cable fixation in the existing heating equipment. Through the cooperation of the locking plate and the locking head in the clamping device, combined with the structural design of the driving assembly and the pin joint member, efficient clamping and fixation of the cable are realized. The combination of the threaded column and the handle makes the operation more convenient, and the user can adjust the distance between the locking plate and the locking head by simply rotating the handle, which improves the installation and maintenance efficiency of the equipment, ensures more reliable fixation of the cable, and avoids the safety hazards caused by loose cable.

[0026] The observation window integrated into the clamping device allows users to visually inspect the cable's fixation status during installation and operation, facilitating the quick identification and resolution of potential problems. This observation window design not only improves operational convenience but also enhances the controllability of equipment operation, offering a significant advantage over existing technologies that lack real-time inspection capabilities.

[0027] By using the pin connector in conjunction with the locking handle, this invention can further shorten the distance between the locking plate and the locking head when the locking handle is pressed, thereby achieving secondary cable fixation. This design significantly improves the clamping force of the cable, making the fixation effect more stable, while reducing the risk of equipment failure caused by loosening, and is safer and more reliable than existing technologies.

[0028] This invention also optimizes the connection method between the inner liner and the sleeve, using screws for fixing and aligning the connecting holes and threaded holes to ensure stable installation and uniform stress distribution. This design improves the structural stability of the entire device, extends its service life, and overcomes the problem of loosening at the connection points in existing equipment. Furthermore, the symmetrical layout of the connecting holes and threaded holes facilitates quick assembly and disassembly of the equipment, simplifying maintenance operations.

[0048] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0049] See Figures 1-7 A solar-powered heating unit combining a solar panel and a ground source heat pump includes a body 1. A photovoltaic panel 3 is mounted on the top of the body 1. One end of the photovoltaic panel 3 is connected to the body 1 via a bracket 2, which is L-shaped and used to support the photovoltaic panel 3 and provide stability. A clamping device 4 is installed on the side of the body 1. The clamping device 4 includes an inner lining plate 41 inside the body 1 and a sleeve 42 outside the body 1. The inner lining plate 41 and the sleeve 42 are evenly connected by multiple screws to ensure the structural rigidity and stability. A rectangular observation window 422 is provided through the outer surface of the sleeve 42 for easy observation of the heating elements. The cable is in a certain state; a locking plate 423 and a locking head 424 are fixedly connected to the outer sides of the two open ends of the sleeve 42, respectively. The locking plate 423 and the locking head 424 are made of high-strength alloy to improve durability and corrosion resistance. The locking plate 423 and the locking head 424 are connected by a drive assembly 43. The drive assembly 43 includes a threaded post 431 that passes through the locking plate 423 and the locking head 424. One end of the threaded post 431 is connected to a nut 432. By tightening the nut 432, the distance between the locking plate 423 and the locking head 424 can be shortened, thereby achieving the clamping and fixing of the cable.

[0050] See Figure 2 and Figure 5A locking element 433 is sleeved in the middle of the threaded post 431. The locking element 433 is made of plastic to avoid damaging the cable surface. The locking element 433 is engaged with the locking head 424 through a slot to ensure that the threaded post 431 remains stable when rotating. A handle 4311 is fixedly connected to one end of the threaded post 431. The handle 4311 has a T-shaped design to facilitate the operator to apply force to rotate the threaded post 431. When rotating the handle 4311, the engaging structure of the locking element 433 can further reduce the sliding friction of the threaded post 431, thereby improving the operating efficiency.

[0051] See Figures 4-6 A pin 44 is also fitted on the threaded post 431. The pin 44 is located inside the locking head 424 and is fixed to the locking head 424 by an interference fit. The top of the pin 44 is rotatably connected to the locking handle 45. The locking handle 45 is a lever design and its structure is made of high-strength composite material to ensure long-term reliability. When the locking handle 45 is pressed down, the distance between the locking plate 423 and the locking head 424 is further shortened by the lever action, thereby enhancing the clamping force on the cable.

[0052] See Figures 6-7 A circular third through hole 441 is provided through the center of the side of the pin connector 44, and the threaded post 431 passes through the third through hole 441 to ensure that the pin connector 44 can slide freely on the threaded post 431; pin holes 442 are symmetrically provided through both sides of the pin connector 44, and the pin holes 442 are rotatably connected to the pin plate 451. One end of the pin plate 451 is fixed to the pin hole 442 by a hinge structure, and the other end is used to support the movement of the locking handle 45; the design of the pin plate 451 takes into account the torque balance and can evenly distribute the pressure generated during the pressing process.

[0053] See Figure 7 The other end of the locking handle 45 is fixedly connected to a pressing head 452. The pressing head 452 has an arc-shaped design, which conforms to ergonomics and makes it easy for the operator to apply force. The pressing head 452 is covered with anti-slip rubber, which improves the safety and comfort of operation.

[0054] See Figures 2-4 A first through hole 411 is provided through the center of the side of the inner lining plate 41. The diameter of the first through hole 411 is adapted to the diameter of the cable for the cable to pass through. One end of the sleeve 42 is fixedly connected to the inner lining plate 41 through a connecting plate 421. A second through hole 4212 corresponding to the first through hole 411 is provided through the center of the side of the connecting plate 421. The positions of the first through hole 411 and the second through hole 4212 are precisely aligned to facilitate the smooth installation and fixation of the cable.

[0055] See Figures 2-4The inner liner plate 41 has symmetrical through-holes 412 on its side, and the connecting plate 421 has symmetrical through-holes 4211 corresponding to the through-holes 412 on its side. The inner liner plate 41 and the connecting plate 421 are tightly fixed by screws, thereby further improving the stability and reliability of the clamping device 4. The arrangement of the through-holes 412 and the threaded holes 4211 is symmetrical, ensuring uniform stress distribution after assembly.

[0056] The working principle of this utility model is as follows:

[0057] Insert the wire harness into one end of the sleeve 42 and let the connector of the wire harness pass through the second through hole 4212 and the first through hole 411, and then connect the connector to the socket inside the body 1.

[0058] Next, hold the handle 4311 with your hand and turn it clockwise. As the handle 4311 turns, the locking plate 423 and the locking head 424 will move closer to each other. As the locking plate 423 and the locking head 424 move closer to each other, the sleeve 42 will be tightly wrapped around the wire harness.

[0059] Finally, hold the pressing head 452 with your hand and move the locking handle 45 toward the position of the handle 4311. During this process, the pin plate 451 will squeeze the outside of the locking head 424, so that the locking head 424 can move closer to the locking plate 423, thereby further locking the wire harness with the sleeve 42.

[0060] Compared with the technical solution in the solar photovoltaic water source heat pump heating unit disclosed in CN219177797U, the clamping device 4 makes it more convenient and secure to fix the cables.

[0061] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
