Description

Technical Field

[0001] The present invention relates to the technical field of CO2 heat pumps, and particularly to a CO2 heat pump that is convenient for installation. Background Art

[0002] As is well known, a CO2 heat pump (also known as a carbon dioxide heat pump) is a heat pump that uses carbon dioxide as a refrigerant and is usually used in applications such as heating, cooling, and hot water heating. The advantages of this type of heat pump include environmental friendliness (due to the relatively small climate impact of carbon dioxide), high energy efficiency, and good working performance (in low-temperature environments).

[0003] Existing CO2 heat pumps are generally not convenient for installation. Even though existing CO2 heat pumps are assembled and various devices are integrated in a housing, when installing a CO2 heat pump, the entire CO2 heat pump still needs to be moved to the installation location. When the entire CO2 heat pump is moved, it generally relies on multiple workers to carry it to the installation location. If the carrying distance is far, a large amount of time and manpower will be wasted. Summary of the Invention

Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1-4 , a CO2 heat pump that is convenient for installation, including a base 1, a limit plate 22, and a main body 6. The main body 6 is placed on the top of the base 1. One end of the limit plate 22 is connected to the top of the base 1, and one side of the limit plate 22 is in contact with the side of the main body 6. It further includes:

[0027] Sliding assembly, the sliding assembly is arranged on the base 1, the sliding assembly includes a bearing plate 3, a hydraulic assembly 4 and a pulley assembly 5, one end of the bearing plate 3 is connected to the base 1, one end of the hydraulic assembly 4 is connected to the bottom of the bearing plate 3, the other end of the hydraulic assembly 4 is connected to the pulley assembly 5, and a plurality of the sliding assemblies are provided, such as Figure 1 shown, first, the staff pushes the equipment to the designated installation position, and the installation is generally outdoors on a flat surface. Then, the hydraulic assembly 4 on the bearing plate 3 is started to drive the pulley assembly 5 to contract, so that the base 1 contacts the ground and the equipment is fixed. The hydraulic assembly 4 is a conventional technology on the market and is driven by a hydraulic cylinder, and will not be described in detail here;

[0028] Rolling mechanism 7, the rolling mechanism 7 includes a slot 8, a circular groove and a bearing column 9, the slot 8 is opened on the base 1, a plurality of circular grooves are opened, a plurality of the circular grooves are opened on the slot 8, a plurality of bearing columns 9 are provided, and a plurality of the bearing columns 9 respectively extend into a plurality of the circular grooves;

[0029] Traction mechanism 10, the traction mechanism 10 includes a frame 11, a cylinder 12, a round block 13 and a traction assembly 14. The frame 11 is arranged on the top of the base 1. Both ends of the cylinder 12 pass through the frame 11 and are connected to one end of the round block 13. There are two traction assemblies 14. The traction assembly 14 includes a connecting plate 15, a motor 16, a wire groove 17, a Kevlar rope 18, an iron block 20 and an electromagnet 21. One end of the connecting plate 15 is connected to the frame 11. One end of the motor 16 is connected to the connecting plate 15. The output end of the motor 16 is connected to the round block 13. The wire groove 17 is opened on the cylinder 12. One end of the Kevlar rope 18 is connected to the inner wall of the wire groove 17. The other end of the Kevlar rope 18 is connected to the iron block 20. One end of the iron block 20 is in contact with the side of the body 6. The two iron blocks 20 on the two traction mechanisms 10 are connected by the electromagnet 21. Then the staff holds the body 6. While pushing the body 6, start the motor 16 on the connecting plate 15 to drive the cylinder 12 passing through the frame 11 on the round block 13 to rotate, so that the Kevlar rope 18 extends out and drives the iron block 20 to move. The staff needs to push the body 6 at the same time to keep one side of the body 6 always in contact with the iron block 20. The side of the iron block 20 in contact with the body 6 is provided with a rubber layer to prevent the iron block 20 from bruising the body 6. When the staff pushes the body 6 on the base 1, it does not consume a particularly large amount of physical strength. Only a part of the base 1 is horizontal. When the body 6 is pushed to the position of the slot 8, since the slot 8 is inclined, the staff no longer needs to push the body 6. After the body 6 reaches the position of the slot 8, the slot 8 is inclined. By contacting the bearing column 9 in the slot 8, the bearing column 9 is arranged in the circular groove of the inner wall of the slot 8 of the slot 8, and the bearing column 9 can rotate, so that the body 6 can move quickly. When the body 6 is about to be separated from the base 1, turn off the electromagnet 21 to make the electromagnet 21 no longer adsorb the two iron blocks 20 and separate the two iron blocks 20. Then the staff slowly separates the body 6 from the base 1, and the body 6 can be moved to the designated installation position. Multiple staff members perform fine-tuning, and the body 6 can be placed in the appropriate position. Then, using external equipment, the equipment can be installed. When the body 6 needs to be moved from one position to another, first start the sliding component to make the pulley component 5 contact the ground, push the equipment to the side of the body 6. Multiple staff members carry the body 6 to the position of the slot 8 to make the bottom of the body 6 contact the bearing column 9. Then, the iron block 20 on the Kevlar rope 18 of the traction assembly 14 contacts the body 6, and the two iron blocks 20 are adsorbed together by the electromagnet 21. Then, by starting the motor 16 on the traction assembly 14, drive the Kevlar rope 18 to rotate so that the Kevlar rope 18 is retracted into the wire groove 17. When the body 6 is being towed, the staff needs to pay attention at all times to avoid the body 6 from tipping over. When one side of the body 6 contacts the limit plate 22, the work is completed. Then install the above steps.It can be separated from the device, and no specific description will be given here.

[0030] During the actual use of the above device, after the main body 6 is moved to the position of the slot 8, it is prone to tipping. For this reason, an auxiliary mechanism 23 is further provided on the base 1. The auxiliary mechanism 23 includes an electric push rod 24, a connecting rod 25 and an auxiliary plate 26. One end of the electric push rod 24 is connected to the base 1, the other end of the electric push rod 24 is connected to one end of the connecting rod 25, and the other end of the connecting rod 25 is connected to the auxiliary plate 26. There are two groups of the auxiliary mechanism 23. By starting the electric push rod 24, the auxiliary plate 26 on the connecting rod 25 is driven to move, so that the auxiliary plate 26 is adjusted to a suitable position, and the auxiliary plate 26 blocks both sides of the slot 8, which can prevent the main body 6 from tipping after moving to the position of the slot 8.

[0031] During the actual use of the above device, the Kevlar rope 18 is prone to instability. For this reason, the traction assembly 14 further includes a limit block 19. The bottom of the limit block 19 is connected to the top of the base 1. A round hole is opened on the limit block 19, and the size of the round hole is larger than the size of the Kevlar rope 18. The Kevlar rope 18 passes through the round hole. There are two limit blocks 19. The Kevlar rope 18 can be limited to a certain extent by passing through the round ring opened on the limit block 19, and the instability of the Kevlar rope 18 can be avoided.

[0032] When the above device is not in use, dust is likely to enter the inside of the slot 8 on the base 1. For this reason, a sealing plate 27 is provided on the base 1. One side of the sealing plate 27 in contact with the top of the base 1 is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the sealing plate 27. When the device is not in use, the sealing plate 27 is used to cover the slot 8 to prevent external dust particles from entering the slot 8, and to avoid the problem that it is inconvenient to clean the inner wall of the slot 8 due to the arrangement of multiple bearing columns 9 in the slot 8. The anti-slip layer provided at the bottom of the sealing plate 27 can prevent the sealing plate 27 from sliding by itself when it contacts the base 1.

[0033] During the actual use of the above device, it is inconvenient to push the whole device. To solve this problem, in this embodiment, a push handle 28 is provided on one side of the base 1. The push handle 28 is fixedly connected to one side of the base 1, and there are two push handles 28.

[0034] During the actual use process of the above device, the bottom of the main body 6 is prone to wear. For this reason, a Teflon layer is provided at the bottom of the main body 6. The Teflon layer is fixedly connected to the bottom of the main body 6. The Teflon layer is provided at the bottom of the main body 6, and the Teflon layer has the advantages of low friction coefficient, wear resistance, corrosion resistance, etc., which can prevent the bottom of the main body 6 from being worn.

[0035] In order to improve the overall stability of the device, in this embodiment, two sets of the auxiliary mechanisms 23 are provided, and a plurality of the sliding mechanisms 2 are symmetrically arranged.

[0036] In this structure, a power supply mechanism for the motor 16 is provided inside the base 1, which can supply power to the device. A charging port is provided on one side of the base 1. When the power supply mechanism for the motor 16 runs out of power, it can charge the power supply mechanism for the motor 16. The power supply mechanism for the motor 16 is a structure such as a storage battery, which will not be specifically described here. The electric push rod 24 in the text is a conventional technology on the market, including a telescopic shell, a motor 16, a lead screw drive structure, a switch and other components. The specific working principle is well known to those skilled in the art and will not be specifically described here. The main body 6 in the text is a conventional CO2 heat pump on the market, including a compressor, a condenser, a throttling device and an evaporator, etc., which will not be specifically described here. The control mode of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the power supply belong to the common knowledge in the art. And the present invention is mainly used to protect the mechanical device, so the control mode and wiring layout of the present invention will not be further explained in detail. The dimensions of all components in this structure need to be produced according to the actual situation and will not be specifically described here. The dimensions of the iron block 20 in this structure are not specifically limited here. The iron block 20 needs to be selected according to the width of the main body 6 and will not be specifically described here. The Kevlar rope 18 is tied to the wire groove 17, and methods such as double figure-eight knots are used, which are not specifically limited here. When the size of the iron block 20 needs to be changed, the Kevlar rope 18 can be separated from the wire groove 17, which will not be specifically described here. This structure can be applied to most sizes of CO2 heat pumps, and there are some sizes that this structure is not suitable for, which will not be specifically described here.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
