Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to an evaporator tower for an air source heat pump. Background Technology

[0002] The evaporator is a very important component among the four major components of refrigeration. Low-temperature condensed liquid exchanges heat with the outside air through the evaporator, vaporizing and absorbing heat to achieve the cooling effect. Air source heat pumps require the use of an evaporator when in operation.

[0003] However, current evaporators have some shortcomings. When the evaporator is in use, high-temperature gas from the outside enters the evaporator. After the gas comes into contact with the water in the water pipe, its temperature drops. At this time, the gas temperature drops and is discharged from another pipe. When the evaporator is being repaired, it needs to be disconnected from the external pipe. During the disconnection and maintenance, because the disconnection point of the evaporator is exposed, foreign objects can easily enter the interior of the evaporator, which will affect the performance of the evaporator. Utility Model Content

[0004] The main objective of this invention is to provide an evaporator tower for an air source heat pump, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An evaporator tower for an air source heat pump includes an evaporator tower body. A water inlet pipe is fixedly installed on the upper surface of the evaporator tower body, and a water outlet pipe is fixedly installed on the lower surface of the evaporator tower body. An air inlet pipe is fixedly installed on the surface of the evaporator tower body near the top, and an air outlet pipe is fixedly installed on the surface of the evaporator tower body near the bottom. A support frame is fixedly fitted on the surface of the evaporator tower body near the top and bottom, and a protective frame is movably installed between the support frames. A dual-shaft motor is fixedly installed inside the protective frame.

[0007] As a preferred technical solution of this application, the protective frame includes a connecting cover, a protective cover, an arc-shaped limiting slide bar, and a handle. The protective cover is fixedly installed on the upper and lower surfaces of the connecting cover, and the arc-shaped limiting slide bar is fixedly installed on the upper and lower surfaces of the protective cover at the rear end. The handle is fixedly installed on the lower surface of the protective cover below the connecting cover.

[0008] As a preferred technical solution of this application, the support frame includes a first fixing ring, a second fixing ring, and a connecting rod. The connecting rod is fixedly installed between the first fixing ring and the second fixing ring, and a positioning groove is formed on the upper surface of the first fixing ring.

[0009] As a preferred technical solution of this application, the number of connecting rods is three, the number of positioning grooves is two, and the curved surfaces of the first fixing ring and the second fixing ring are provided with annular limiting grooves.

[0010] As a preferred technical solution of this application, a threaded shaft is fixedly installed at the output end of the dual-axis motor, a threaded sleeve block is sleeved on the surface of the dual-axis motor, and a positioning rod is fixedly installed on the upper surface of one end of the threaded sleeve block.

[0011] As a preferred technical solution of this application, the dual-axis motor is fixed in the connecting cover, and one end of the threaded shaft is movably connected to the protective cover.

[0012] As a preferred technical solution of this application, the arc-shaped limiting slide bar is embedded in the annular limiting groove, the positioning rod is embedded in the positioning groove, and the other end surface of the threaded sleeve block is in contact with the inner front surface of the connecting cover.

[0013] Compared with the prior art, this utility model proposes a self-cleaning solar street light, which has the following beneficial effects:

[0014] In this invention, by setting up a support frame, a protective frame, and a dual-axis motor in cooperation, after the inlet and outlet pipes are disconnected from the external pipeline, the dual-axis motor is started by an external device. The dual-axis motor drives the threaded shaft to rotate, and the rotating threaded shaft controls the two threaded sleeves to move closer to each other. This allows the positioning rod on the threaded sleeve to exit from the positioning slots of the support frame above and below the evaporator tower. Then, the protective frame can be rotated by a lever until the protective cover of the protective frame covers the inlet and outlet pipes respectively. Finally, the dual-axis motor is controlled by the external device to rotate in reverse, so that the positioning rod is embedded in another positioning slot of the support frame, thereby positioning the protective frame. This prevents foreign objects from entering the interior of the evaporator during evaporator maintenance. Attached Figure Description

A water inlet pipe 2 is fixedly installed on the upper surface of the evaporator tower body 1, a water outlet pipe 3 is fixedly installed on the lower surface of the evaporator tower body 1, an air inlet pipe 4 is fixedly installed on the surface of the evaporator tower body 1 near the top, an air outlet pipe 5 is fixedly installed on the surface of the evaporator tower body 1 near the bottom, and a support frame 6 is fixedly fitted on the surface of the evaporator tower body 1 near the top and bottom. A protective frame 7 is movably installed between the support frames 6, and a dual-shaft motor 8 is fixedly installed inside the protective frame 7.

[0022] The protective frame 7 includes a connecting cover 701, a protective cover 702, an arc-shaped limiting slide bar 703, and a handle 704. The protective cover 702 is fixedly installed on the upper and lower surfaces of the connecting cover 701. The arc-shaped limiting slide bar 703 is fixedly installed on the upper and lower surfaces of the protective cover 702, and located at the rear end. The handle 704 is fixedly installed on the lower surface of the protective cover 702 below the connecting cover 701. When in use, the protective cover 702 can shield and protect the air inlet pipe 4 and air outlet pipe 5 after disconnection. The support frame 6 includes a first fixing ring 602, a second fixing ring 601, and a connecting rod 604. The connecting rod 604 is fixedly installed between the first fixing ring 602 and the second fixing ring 601. A positioning groove 603 is formed on the upper surface of the first fixing ring 602. There are three connecting rods 604, and the positioning grooves 603... There are two fixed rings, No. 1 fixed ring 602 and No. 2 fixed ring 601, with annular limiting grooves 605 on their curved surfaces; a threaded shaft 801 is fixedly installed at the output end of the dual-axis motor 8, and a threaded sleeve block 802 is fitted on the surface of the dual-axis motor 8. A positioning rod 803 is fixedly installed on the upper surface of one end of the threaded sleeve block 802.
