Description

Technical Field

[0001] The utility model relates to the technical field of heat pump units, in particular to a multi-state air source heat pump unit. Background Art

[0002] A multi-state air source heat pump unit is a heat pump system that utilizes the air source for multiple function conversions. It combines the basic principle of an air source heat pump and achieves multiple working modes and a higher energy efficiency ratio through advanced technical means.

[0003] Currently, the existing multi-state air source heat pump units cannot provide a sunshade and rain shelter environment for maintenance personnel, enabling them to work in a more suitable environment, resulting in a reduction in the efficiency of maintenance work. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the drawback in the prior art that it cannot provide a sunshade and rain shelter environment for maintenance personnel, enabling them to work in a more suitable environment, resulting in a reduction in the efficiency of maintenance work, and to propose a multi-state air source heat pump unit.

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

[0006] A multi-state air source heat pump unit, comprising:

[0007] A unit main body, a top cover is fixedly arranged on the top of the unit main body, and two support frames are symmetrically and fixedly arranged at the bottom of the unit main body;

[0008] A shielding component, which is arranged on the top cover and is used to shade and shelter maintenance personnel from the sun and rain during maintenance;

[0009] A buffering component, which is arranged on the support frame and is used to buffer the vibration generated during the operation of the unit.

[0010] In a possible design, the shielding component includes a receiving groove opened on one side of the top cover, and sliding grooves are arranged on both sides of the receiving groove. Slide frames are slidably arranged inside the two sliding grooves. One ends of the two slide frames are hinged with support rods, one ends of the two support rods are hinged with connecting blocks, sliding columns are fixedly arranged at the ends of the two connecting blocks close to each other, connecting seats are slidably sleeved outside the ends of the two sliding columns close to each other, reset springs are arranged inside the two connecting seats, one end of the reset spring is fixedly connected with the sliding column, and the other end of the reset spring is fixedly connected with the inner wall of the connecting seat. A shielding cloth is fixedly arranged on one side of the two support rods close to each other.

[0011] In a possible design, the buffer assembly includes four threaded rods respectively passing through and threadedly connected to both ends of two support frames. At the bottom of each of the four threaded rods, a top seat is rotatably provided. At the bottom of each of the four top seats, a bottom seat is slidably provided. A damper is fixedly provided inside the top seat and the bottom seat. The bottom of the damper is fixedly connected to the bottom wall of the bottom seat, and the piston end of the damper is fixedly connected to the top wall of the top seat. A buffer spring is sleeved outside the damper between the bottom seat and the top seat. The bottom end of the buffer spring is fixedly connected to the bottom wall of the bottom seat, and the top end of the buffer spring is fixedly connected to the top wall of the top seat. Anti-slip pads are fixedly provided at the bottom of each of the four bottom seats.

[0012] In a possible design, on both sides of the inner wall of the top cover accommodating groove, the same lead screw is rotatably provided, and a motor is fixedly provided on one side of the accommodating groove. One end of the output shaft of the motor is fixedly connected to the lead screw. A fixed block is fixedly provided on one side of the sliding frame, and the fixed block is threadedly connected to the lead screw.

[0013] In a possible design, adjustment knobs are fixedly provided at the top of each of the four threaded rods, and locking nuts are threadedly connected to the outside of each of the four threaded rods below the support frame.

[0014] In a possible design, on one side of the unit main body, inspection doors symmetrically arranged are hinged through hinges, and the two inspection doors are locked and fixed through a buckle. An audible and visual alarm is electrically fixedly provided on the top of the unit main body.

[0015] In this application, when starting to use, first symmetrically fix the two support frames at the bottom of the unit main body to ensure stable installation. Subsequently, at both ends of each support frame, install four buffer assemblies through threaded connection of the threaded rods. Then, according to the ground conditions, rotate the adjustment knobs. When the adjustment knobs rotate, they drive the threaded rods to rotate synchronously. When the threaded rods rotate, they move downward on the support frames. When the threaded rods move downward, they push the buffer assemblies closer to the ground until the bottom of the buffer assemblies abuts against the ground, and then stop rotating the adjustment knobs. Then, turn the two locking nuts above and below the threaded rods so that the two locking nuts respectively abut against the bottom of the support frames to complete the position limitation of the threaded rods. Subsequently, according to the above operation method, sequentially rotate the other adjustment knobs until all the buffer assemblies abut against the ground to complete the support of the unit.

[0016] Subsequently, start the multi-state air source heat pump unit. The unit starts to work normally, performing heating or cooling cycles. During the operation of the unit, the generated vibration is transmitted to the buffer assembly through the support frame. At this time, the damper itself slows down the movement of the unit when it is vibrated through internal friction or resistance, consuming the vibration energy, so as to effectively absorb and reduce the amplitude and frequency of the vibration generated when the unit is working. The buffer spring is sleeved outside the damper and buffers the received vibration through its own elastic principle, thereby further enhancing the anti-vibration effect and reducing the vibration generated during the operation of the unit.

[0017] When the unit needs to be overhauled, first turn off the power supply of the unit to ensure safety. Subsequently, start the motor. One end of the output shaft of the motor drives the screw rod to rotate. While the screw rod rotates, it drives the carriage to move along the chute through the fixed block. While the carriage is moving, it pushes the entire shielding assembly out of the receiving groove of the top cover. When the shielding assembly is pushed out, under the elastic force of the return spring, it pushes the sliding column out of the connecting seat, and drives the support rod to expand in a fan shape through the connecting block. At the same time, the support rod rotates and expands on the carriage. When the support rod is fully expanded, the shielding cloth is unfolded. When the light is strong, it can effectively prevent the strong light from bringing discomfort to the body of the maintenance personnel, especially the eyes, and affecting the operation of the maintenance personnel. Because of the waterproof coating on the surface of the shielding cloth, it can also play a role in shielding rain and snow during emergency repairs in rainy and snowy weather. Subsequently, the staff unfastens the buckle, opens the inspection door, and performs inspection and maintenance work on the inside of the unit. After the inspection is completed, close the inspection door and lock it with the buckle.

[0018] During the operation of the unit, if abnormal conditions occur (such as too high temperature, abnormal pressure, etc.), the sound and light alarm will be automatically triggered to issue a sound and light alarm to remind the maintenance personnel to deal with it in time.

[0019] The utility model has the following beneficial effects:

[0020] In the utility model, through the setting of the shielding assembly, when the unit needs to be overhauled, the motor drives the screw rod to rotate, pushes the carriage to move along the chute, drives the support rod to move out, and under the elastic force of the return spring, pushes the sliding column out of the connecting seat, and drives the support rod to expand in a fan shape through the connecting block. When the support rod reaches the predetermined position, the shielding cloth is fully unfolded, providing a sunshade and rainshield environment for the maintenance personnel, enabling the maintenance personnel to work in a more suitable environment, thereby improving work efficiency.

[0021] In the utility model, through the setting of the buffer assembly, when the vibration generated during the operation of the unit is transmitted to the support frame, the damper and the buffer spring will work together to effectively absorb and reduce the amplitude and frequency of the vibration generated during the operation of the unit, reduce the vibration generated during the operation of the unit, and protect the unit from damage.

[0022] In the present utility model, through the arrangement of the threaded rod, the adjusting knob and the locking nut, by rotating the adjusting knob, the height of the threaded rod is adjusted, thereby driving the buffer assembly to rise or fall to adapt to different working heights, so as to be flexibly adjusted according to the ground conditions, ensuring that the unit can work in a horizontal state, which helps to reduce the safety risks caused by vibration and shaking due to uneven terrain, thereby improving the operating efficiency and safety of the unit;

[0023] Through the arrangement of the shielding assembly in the present utility model, an environment of sunshade and rain protection can be provided for maintenance personnel, enabling the maintenance personnel to work in a more suitable environment, thereby improving work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Embodiment 1

[0031] Refer to Figures 1-4 , the heat pump unit includes:

[0032] The main body of the unit 1, as the core component, is fixedly installed with a top cover 2 at its top, which can provide shelter for the main body of the unit 1 and reduce the damage to the maintenance equipment caused by weather conditions. At its bottom, two support frames 3 are symmetrically arranged to stably support the entire unit.

[0033] The shielding component mainly includes a receiving groove, a sliding groove, a sliding frame 7, a support rod 8, a connecting block 10, a sliding column 11, a connecting seat 12, a return spring 13 and a shielding cloth 9 (with a waterproof coating on its surface) on the top cover 2. When the unit needs to be overhauled, the maintenance personnel can start the motor 15 to drive the screw rod 14 to rotate. While the screw rod 14 rotates, it drives the sliding frame 7 to move along the sliding groove through the fixed block 16. While the sliding frame 7 is moving, the whole shielding component is pushed out from the receiving groove of the top cover 2. When the shielding component is being pushed out, under the elastic force of the return spring 13, the sliding column 11 is pushed out of the connecting seat 12, and the support rod 8 is driven by the connecting block 10 to expand in a fan shape. At the same time, the support rod 8 rotates and unfolds on the sliding frame 7. When the support rod 8 is fully unfolded, the shielding cloth 9 is unfolded accordingly. In strong light, it can effectively prevent the strong light from bringing discomfort to the body of the maintenance personnel, especially the eyes, and affecting the operation of the maintenance personnel. Because of the waterproof coating on the surface of the shielding cloth 9, it can also play a role in shielding rain and snow during emergency maintenance in rainy and snowy weather. After the overhaul is completed, the motor 15 is controlled to rotate in the reverse direction, so that the sliding frame 7 retracts, the support rod 8 folds accordingly, and the shielding cloth 9 is retracted and stored in the receiving groove of the top cover 2.

[0034] The buffer component includes a threaded rod 17, a top seat 18, a bottom seat 19, a damper 20, a buffer spring 21, an adjustment knob 22 and a locking nut 23. The four threaded rods 17 are respectively installed through threading at both ends of the support frame 3. By rotating the adjustment knob 22, the height of the threaded rod 17 is adjusted, thereby driving the buffer component to rise or fall to adapt to different working heights, so as to be flexibly adjusted according to the ground conditions to ensure that the unit can work in a horizontal state, which helps to reduce the safety risks caused by vibration and shaking due to uneven terrain, thereby improving the operating efficiency and safety of the unit. Subsequently, the locking nut 23 is tightened on the threaded rod 17 to limit its position to ensure that the threaded rod 17 is fixed. A damper 20 and a buffer spring 21 are installed between each top seat 18 and the bottom seat 19; when the vibration generated during the operation of the unit is transmitted to the support frame 3, the damper 20 and the buffer spring 21 will act together to effectively absorb and reduce the amplitude and frequency of the vibration generated during the operation of the unit, reduce the vibration generated during the operation of the unit, and protect the unit from damage. The anti-slip pad 24 is fixedly installed at the bottom of the bottom seat 19 to increase the friction with the ground and prevent the unit from shifting during the operation process.

[0035] This application can be used in the technical field of multi-energy state air source heat pump units, and can also be used in other fields applicable to this application.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, Embodiment 2 further includes: a multi-state air source heat pump unit, which is applied to the technical field of multi-state air source heat pump units. Two symmetrical maintenance doors 5 are provided on one side of the unit main body 1 and are locked and fixed by buckles 6, facilitating maintenance personnel to perform inspections and maintenance on the interior of the unit.

[0038] An audible and visual alarm 4, installed on the top of the unit main body 1, is used to issue an alarm when the unit has an abnormal situation, reminding relevant personnel to handle it in a timely manner.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the audible and visual alarm 4 and the motor 15 are common knowledge, and they both belong to conventional means or well-known common sense. Therefore, they will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.
