Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to an air source heat pump with a protection mechanism for industrial heating. Background Art

[0002] An air-source heat pump is a device that uses heat from the air to provide heating, cooling, or hot water. Using heat pump technology, it raises the low-temperature heat in the air to a suitable temperature and then transfers it to the building or water system. An air-source heat pump primarily consists of a compressor, evaporator, condenser, and expansion valve.

[0003] Based on the principle of air-source heat pumps, when industrial hot water is needed, an air-source heat pump can be used to generate hot water for factory use. An air-source heat pump water heater utilizes heat from the air to heat water. Combining heat pump technology with the functions of a water heater, it efficiently transfers heat from the air to water, providing hot water. Compared to traditional electric or gas water heaters, air-source heat pump water heaters are more energy-efficient and environmentally friendly.

[0004] The efficiency of existing air source heat pump water heaters is greatly affected by the external ambient temperature, especially under extremely cold conditions, the performance will decline, and air source heat pump water heaters usually need to be installed outdoors in a well-ventilated area, which requires a certain amount of space. Therefore, during the use of the air source heat pump water heater, the external ambient temperature has a greater impact on the thermal efficiency of the air source heat pump, and when used in some rainy and snowy weather, rainwater and snow water fall from above and accumulate on the outside of the equipment. The melting and evaporation of water in the rain and snow will absorb heat, which will further lead to a decrease in the heating efficiency of the air source heat pump water heater. Moreover, when extreme weather, such as freezing rain, hail, etc., impacts the heat dissipation blades of the heat exchanger, it is easy to cause the heat sink designed to be thin and light for heat dissipation efficiency to deform, causing damage to the equipment. In view of the above problems, an air source heat pump with a protective mechanism for industrial heating is proposed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-8 , the utility model provides a technical solution: an air source heat pump with a protective mechanism for industrial heating, including a heat source pump main body 1. The heat source pump main body 1 is equipped with a protective device 2 on the outside, and several sets of protective devices 2 are electrically connected to an identification device 3;

[0029] The protection device 2 includes a bracket 21, the top of which is equipped with a guide tube 22, and the interior of the guide tube 22 is equipped with a plurality of sets of protective blades 23 stacked layer by layer, and all the protective blades 23 rotate synchronously;

[0030] The identification device 3 includes a base 31, a fixed plate 31 is installed on the top of the base 31, a floating plate 35 that can be relatively displaced is installed on the top of the fixed plate 31, a sensor is installed between the floating plate 35 and the fixed plate 34, the sensor is electrically connected to the control module, and the control module is electrically connected to the drive device of the protective blade 23.

[0031] The present invention provides an air source heat pump with a protective mechanism. During use, when the weather changes, when the falling objects fall onto the top of the floating plate and exceed a certain weight or impact force, the sensor on the inner side of the floating plate 35 recognizes the reading and automatically activates the electric push rod 32. The electric push rod 32 drives the rack 28 to move, thereby driving the gear 26 to rotate around the positioning tube 25, and finally driving the protective blade 23 to rotate, providing protection for the top of the air source heat pump 1 when needed, and timely protecting the air source heat pump in extreme outdoor weather conditions, effectively solving the problem that when the existing large-scale air source heat pumps used in industry collect heat in the air, extreme weather such as rain, snow, and hail have a great impact on the heat exchange efficiency of the radiator.

[0032] Specifically, the bracket 21 is composed of at least 4 pillars, 2 of which are shorter than the other 2. The number of pillars of the bracket 21 is an even number. After the whole is combined with the guide tube 22, the guide tube 22 is tilted to one side, and the tilted surface is preferably configured to face the sunlight side. The internal area of ​​the base structure of the combination of the bracket 21 and the pillars is larger than the maximum distance of the air source heat pump. Therefore, when the protective device is installed, the orientation of the overall structure can be adjusted before installation.

[0033] Specifically, there are sleeve holes on both sides of the guide tube 22, and a positioning tube 25 is provided inside the sleeve hole. The positioning tube 25 and the sleeve hole are preferably threadedly connected. The positioning tube is screwed to the inside of the sleeve hole from both sides to realize positioning of both sides of the gear. Bearings can be optionally installed on the inner side of the positioning tube 25. The connection method between the positioning tube 25 and the sleeve hole can also be a welding mode. When assembling the gear, it can be installed from the top of the mounting port 29.

[0034] Specifically, pads 210 are provided on both sides of the interior of the guide tube 22, and a rack 28 is provided on the top of the pad 210. A gear 26 is engaged with the top of the rack 28. The gear 26 is provided between the positioning tubes 25, and the center of the gear 26 is coaxially fixed with the protective blade 23. Connecting shafts are welded on both sides of the protective blade 23 to extend outward, and the connecting shafts are used for assembly with the gear 26. The entire protective mechanism only uses one transmission mechanism consisting of a gear 26, a rack 28 and an electric push rod 27. When the span is large, two sets of synchronous transmissions can also be used.

[0035] Specifically, an electric push rod 27 is installed on one side of the rack 28, and the electric push rod 27 is fixed downwardly and assembled at the bottom of the guide tube 22. The electric push rod 27 is assembled in a back-to-back manner, which can save installation space when in use. By controlling the moving distance, the purpose of adjusting the angle of the protective blade 23 is achieved. When in use, the single tooth displacement distance of the gear 26 and the rack 28 is input into the background computer. When in use, according to the gear rotation angle corresponding to the number of teeth, after calculation, the single tooth displacement distance can be moved multiple times to achieve control of the rotation angle of the gear 26.

[0036] During use, when raindrops with the weight and impact force required for protection fall on the top of the floating plate, the floating plate 35 presses down on the sensor. After obtaining the reading, the background system will only need to identify and compare the pressure reading if it exceeds the set range, and immediately start the protection mechanism. The electric push rod 27 moves to the maximum position, and the protective blade 23 is quickly closed to achieve the purpose of protection. In normal rain or snow conditions, the background system controls the protective blade 23 to rotate slowly or to a suitable angle as needed to guide rainwater discharge. In rainless weather, the angle of the protective blade 23 can be adjusted according to the daily solar altitude of the installation location, so that the air source heat pump 1 below can be exposed to sunlight, thereby improving heat exchange efficiency and enhancing heat absorption efficiency. It can also be adjusted to reduce the thermal efficiency of the system to achieve the purpose of controlling the extreme thermal energy efficiency of the system.

[0037] Specifically, the top of the guide tube 22 is evenly provided with mounting openings 29 , which are used for mounting the gear 26 .

[0038] Specifically, a protective cover 24 is provided on the top of the guide tube 22. The top and both sides of the protective cover 24 are arc-shaped structures. An opening is provided at the bottom of the protective cover 24, and the protective cover 24 is fixedly assembled on the outer surface of the mounting port 29 above the guide tube 22. The longitudinal cross-section and the cross-sections at both ends are elliptical structures, which can maximize the protection against the falling or accumulation of hail, snowflakes and other structures with high difficulty, and effectively protect the safety of the driving device during normal time.

[0039] Specifically, the identification device 3 includes a base 31 , a support rod 32 is welded to the top of the base 31 , a fixing plate 34 is welded to the top of the support rod 32 , and the fixing plate 34 is fixedly assembled on the top of the support rod 32 .

[0040] Specifically, a diagonal brace 33 is welded to the outer side of the support rod 32 .

[0041] The floating plate 35 and the fixed plate 34 can be connected by an elastic structure such as a gas spring or a spring, which will not affect the transmission of force during use. In addition, when the floating plate 35 and the fixed plate 34 are displaced, the sensor can be directly activated and will not be directly activated by the influence of gravity.

[0042] Mirror structures can be attached to the inner side and top of the protective blade 23, which can assist in the refraction of sunlight when in use, and are used to control the direction of sunlight, and use the heat energy of sunlight to provide the temperature around the air source heat pump, thereby increasing the amount of heat obtained in the air during heat exchange of the air source heat pump.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
