Description

Technical Field

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

[0002] Air source heat pump unit, also known as air source heat pump unit, is a device that uses the heat in outdoor air as a heat source for heating or cooling. It absorbs environmental heat energy from the outside air through its evaporator, and then the heat transfer medium is pressurized and heated in the compressor, and then releases heat through the condenser, thereby transferring heat to water or other media to achieve the purpose of heating. It can also be used for cooling.

[0003] Air source heat pumps are energy-efficient and highly efficient, easy to use and install, and are widely used in households, commerce, and industry to provide multiple functions such as hot water supply, indoor heating and cooling. They are particularly suitable for use in areas where no other traditional thermal energy resources are available.

[0004] As a commonly used heating and cooling equipment, its internal metal components are very easy to be damaged due to long-term operation in harsh environments such as outdoor. In order to avoid this problem, the current commonly used solution is to set the air heat source pump unit inside a box for protection. However, although this protection can initially solve the problem, this design fixes the pump inside the device, which causes some troubles in the subsequent cleaning of the pump unit's working environment and pump maintenance. Therefore, an air heat source pump unit with a protective mechanism is proposed, which can effectively protect the pump unit while also providing great convenience for the subsequent pump maintenance. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an air heat source pump unit with a protective mechanism, which has the advantages of high flexibility and good stability, and solves the problem that traditional pump protection devices over-protect the pump, making subsequent maintenance inconvenient.

[0006] In order to achieve the above-mentioned purposes of high flexibility and good stability, the utility model provides the following technical solutions: an air heat source pump unit with a protective mechanism, comprising a box body, a protective component arranged on the outside of the box body, a lifting component used in conjunction with the protective component, and a shielding component arranged on the top of the box body, the protective component comprising a buffer pad arranged on the bottom wall of the box body, a bearing plate movably connected to the top of the buffer pad, a plurality of side baffles fixedly mounted on the top of the bearing plate, a cleaning slot opened at the bottom of the box body, and a heat dissipation mesh plate arranged on the side of the box body.

[0007] Furthermore, the side baffles are fixedly mounted on the top of the bearing plate to form a square notch, and the heat pump group is embedded in the square notch formed by the side baffles.

[0008] Furthermore, the lifting assembly includes a plurality of slides fixedly mounted on the inner wall of the box body, a sliding block slidably connected inside the slide, a plurality of threaded sleeves fixedly mounted on the side of the bearing plate, a threaded rod rotatably connected inside the threaded sleeve, and an adjustment handle fixedly mounted on the top of the threaded rod.

[0009] Furthermore, a plurality of limit sliders are fixedly installed on the side of the side baffle, the limit sliders are embedded in the slide groove of the slide and are slidably connected to the slide, and the side of the sliding block and the bearing plate are fixedly installed.

[0010] Furthermore, the threaded rod passes through the threaded sleeve and is rotationally connected to the threaded sleeve through a thread. The bottom of the threaded rod is rotationally connected to the inner bottom wall of the box. A plurality of limiting sleeves are fixedly installed on the top of the inner side wall of the box. The threaded rod vertically passes through the limiting sleeve and is rotationally connected to the limiting sleeve.

[0011] Furthermore, the shielding assembly includes a support plate movably connected inside the slide, a support rod fixedly installed on the top of the support plate, a protective plate fixedly installed on the top of the support rod, a plurality of ventilation ducts arranged inside the protective plate, and a shielding cover arranged on the top of the ventilation ducts.

[0012] Furthermore, the bottom of the ventilation duct is wrapped around the outside of the air port at the top of the heat pump, a support seat is fixedly installed on the inner wall of the ventilation duct, and the top of the support seat and the bottom of the shielding cover are fixedly installed.

[0013] Furthermore, a plurality of shock-absorbing feet are fixedly installed on the bottom of the box body, and anti-skid rubber pads are fixedly installed on the bottom of the shock-absorbing feet.

[0014] Compared with the prior art, the utility model provides an air heat source pump unit with a protection mechanism, which has the following beneficial effects:

[0015] 1. The air heat source pump unit with a protective mechanism drives the threaded rod to rotate by rotating the adjustment handle, and then drives the threaded sleeve to achieve lifting and lowering. The lifting and lowering of the threaded sleeve drives the load-bearing plate to rise, and the sliding block moves inside the slideway at the same time. The limit sliders arranged on the sides of the side baffles cooperate with the sliding block to move up and down inside the slideway at the same time, which can prevent the pump unit from rotating during the lifting and lowering of the load-bearing plate. The side baffles form a groove-type structure to fix the pump placed on the top of the load-bearing plate to prevent the pump from moving.

[0016] 2. The air heat source pump unit with a protective mechanism always presses the support rod and holds the support plate on the top of the limit slider through the gravity of the protective plate, so that the protective plate is always sealed with the box body when not in operation. The ventilation pipe wraps the air port of the hot air pump, which can protect the air port to a certain extent and prevent foreign matter from entering the air port, solving the problem of excessive protection of the pump by traditional pump protection devices, which makes subsequent maintenance inconvenient.

[0024] The pump unit is stored and fixed by providing a protective component 2, and the pump unit is lifted out of the box by using a lifting component 3, and the shielding component 4 assists the protective component 2 in protecting the pump unit in daily use.

[0025] In this embodiment, the side baffles 23 are fixedly mounted on the top of the bearing plate 22 to form a square notch, and the heat pump unit is embedded in the square notch formed by the side baffles 23 .

[0026] The side baffles 23 are provided to form a groove-shaped structure to fix the pump placed on the top of the bearing plate 22 to prevent the pump from moving.

[0027] In this embodiment, the lifting assembly 3 includes a plurality of slideways 31 fixedly mounted on the inner wall of the box body 1, a sliding block 32 slidably connected inside the slideway 31, a plurality of threaded sleeves 33 fixedly mounted on the side of the supporting plate 22, a threaded rod 34 rotatably connected inside the threaded sleeve 33, and an adjustment handle 35 fixedly mounted on the top of the threaded rod 34.

[0028] By setting the sliding block 32 to be able to move only up and down inside the slideway 31 , the threaded rod 24 cooperates with the threaded sleeve 33 to achieve the purpose of lifting.

[0029] In this embodiment, a plurality of limit sliders 26 are fixedly installed on the side of the side baffle 23 . The limit sliders 26 are embedded in the slide groove of the slideway 31 and are slidably connected to the slideway 31 . The side of the sliding block 32 is fixedly installed on the bearing plate 22 .

[0030] By arranging a limit slider 26 on the side of the side baffle 23 to cooperate with the sliding block 32 to move up and down inside the slideway 31 at the same time, the pump unit can be prevented from rotating during the lifting process of the bearing plate 22.

[0031] In this embodiment, the threaded rod 34 passes through the threaded sleeve 33 and is rotationally connected to the threaded sleeve 33 through a thread. The bottom of the threaded rod 34 is rotationally connected to the inner bottom wall of the box body 1. A plurality of limiting sleeves 36 are fixedly installed on the top of the inner wall of the box body 1. The threaded rod 34 vertically passes through the limiting sleeve 36 and is rotationally connected to the limiting sleeve 36.

[0032] By arranging the threaded sleeve 33 on the outer side of the threaded rod 34 and fixing it on the side of the bearing plate 22 , the rotating adjustment handle 35 drives the threaded rod 34 to rotate and then drives the threaded sleeve 33 to achieve the lifting function.

[0033] In this embodiment, the shielding assembly 4 includes a support plate 41 movably connected to the inside of the slide 31, a support rod 42 fixedly installed on the top of the support plate 41, a protective plate 43 fixedly installed on the top of the support rod 42, a plurality of ventilation ducts 44 arranged inside the protective plate 43, and a shielding cover 45 arranged on the top of the ventilation duct 44.

[0034] By setting the support plate 41 and the support rod 42 to be embedded in the slideway 31, the support rod 42 is always pressed to hold the support plate 41 on the top of the limit slider 26 under the action of gravity of the protection plate 43, so that the protection plate 43 is always sealed with the box body 1 when not operated.

[0035] In this embodiment, the bottom of the ventilation duct 44 is wrapped around the outside of the air port at the top of the heat pump, a support seat 46 is fixedly installed on the inner wall of the ventilation duct 44, and the top of the support seat 46 and the bottom of the shielding cover 45 are fixedly installed.

[0036] By providing a ventilation duct 44 to wrap the air port of the hot air pump, the air port can be protected to a certain extent and foreign matter can be prevented from entering the air port.

[0037] In this embodiment, a plurality of shock-absorbing feet 5 are fixedly mounted on the bottom of the box body 1 , and anti-skid rubber pads are fixedly mounted on the bottom of the shock-absorbing feet 5 .

[0038] The stabilizing effect of the device is increased by providing the shock-absorbing feet 5, and the anti-skid rubber pads can be provided to prevent sliding during the placement operation.

[0039] The working principle of the above embodiment is:

[0040] The threaded rod 34 is driven to rotate by rotating the adjusting handle 35, and then the threaded sleeve 33 is driven to be raised and lowered. The lifting and lowering of the threaded sleeve 33 drives the load-bearing plate 22 to rise, and at the same time, the sliding block 32 moves inside the slide 31. The limiting slider 26 set on the side of the side baffle plate 23 cooperates with the sliding block 32 to move up and down inside the slide 31 at the same time, which can prevent the pump unit from rotating during the lifting and lowering of the load-bearing plate 22. The side baffle plate 23 forms a groove-shaped structure to fix the pump placed on the top of the load-bearing plate 22 to prevent the pump from moving.

[0041] In addition, under the action of gravity, the protection plate 43 always presses the support rod 42 and holds the support plate 41 on the top of the limit slider 26, so that the protection plate 43 is always sealed with the box body 1 when not in operation. The ventilation pipe 44 wraps the air outlet of the hot air pump, which can protect the air outlet to a certain extent and prevent foreign matter from entering the air outlet.

[0042] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
