[0004] 1. The sound generated by the ground source heat pump unit when it is working will be transmitted from the heat dissipation window or vent, resulting in a large noise when the heat pump unit is working;

[0005] In order to solve the above-mentioned problems, this document discloses a ground source heat pump unit with noise reduction function. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that the sound generated by the ground source heat pump unit when working will be transmitted from the heat dissipation window or the vent, resulting in that the heat pump unit still generates relatively large noise when working, and to propose a ground source heat pump unit with noise reduction function.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A ground source heat pump unit with a noise reduction function comprises a box body, wherein the box body is formed by a first shell body and a second shell body being detachably sealed and butted together, and further comprises:

[0009] A placement plate is sealed and slid on the inner wall of the box body, and is used to place the ground source heat pump unit;

[0010] A through slot fixedly provided on the bottom wall of the box body;

[0011] Two main rods are symmetrically fixedly connected to the bottom of the placement plate, and the main rods pass through the through slots. The outer wall of the bottom end of the main rod is fixedly sleeved with a support spring, and the bottom end of the support spring is fixedly connected with a support leg for supporting the placement plate;

[0012] Four L-shaped rods are symmetrically fixedly connected at the four corners of the bottom of the box body, one end of the four L-shaped rods slides through the corresponding support legs, and the two L-shaped rods that conflict with each other are fixed by bolts to support and fix the box body;

[0013] A heat dissipation window is provided on one side of the first shell to facilitate heat dissipation of the ground source heat pump unit;

[0014] A buffer component is arranged inside the box body and is used to buffer the vibration generated by the ground source heat pump unit placed on the top of the plate;

[0015] The noise reduction component is arranged on the inner wall of the heat dissipation window to reduce the sound emitted from the heat dissipation window when the ground source heat pump unit is working.

[0016] In a possible design, the buffer assembly includes a plurality of spring shock absorbers symmetrically fixedly connected to the bottom of the placement plate, the bottom of the spring shock absorber is fixedly connected to a rectangular plate, and the bottom of the rectangular plate is in contact with the bottom wall of the box body.

[0017] In a possible design, a roller is fixedly mounted on the bottom of each rectangular plate, and a rolling groove for cooperating with the roller is opened on the bottom wall of the box.

[0018] In a possible design, the noise reduction component includes two groups of arc-shaped plates installed on the inner wall of the heat dissipation window, and the number of arc-shaped plates in each group is at least two.

[0019] In a possible design, the two groups of arc-shaped plates are staggered.

At the same time, when the sound waves emitted by the ground source heat pump unit work and reach the heat dissipation window, they first connect with the arc surface of the arc plate, and the waveform changes and disperses outward along the arc surfaces on both sides of the arc plate. With the help of sound insulation cotton, the energy of the sound waves is greatly attenuated, thereby achieving the effect of reducing noise.

[0025] In the utility model, the ground source heat pump unit with noise reduction function reduces the decibel of sound transmitted from the heat dissipation window through the noise reduction component;

[0026] In the utility model, an arc plate is provided to consume the energy of sound waves and reduce the decibel of sound. A roller groove is provided to facilitate pulling the first shell and the second shell. A plurality of spring shock absorbers are provided to absorb and consume the vibration generated by the work of the ground source heat pump unit. The device is easy to operate and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Example 1

[0034] Reference Figure 1-Figure 4 A ground source heat pump unit includes a box body 1, which is formed by a first shell 101 and a second shell 102 being detachably sealed and butted together. A placement plate 2 is sealed and slid on the inner wall of the box body 1 for placing the ground source heat pump unit. A through groove 4 is fixedly opened on the bottom wall of the box body 1. Two main rods 3 are symmetrically fixedly connected to the bottom of the placement plate 2, and the main rods 3 pass through the through groove 4. A support spring 5 is fixedly sleeved on the outer wall of the bottom end of the main rod 3. The bottom end of the support spring 5 is fixedly connected with a support leg 6 for supporting the placement plate 2. Four L-shaped rods 7 are symmetrically fixedly connected to the four corners of the bottom of the box body 1. One end of each L-shaped rod 7 slides through the corresponding supporting leg 6, and the two L-shaped rods 7 that are in conflict with each other are fixed by bolts to support and fix the box body 1. The heat dissipation window 12 is opened on one side of the first shell 101 to facilitate the heat dissipation of the ground source heat pump unit. The buffer component is arranged inside the box body 1 to buffer the vibration generated by the ground source heat pump unit on the top of the placement plate 2. The buffer component includes a plurality of spring shock absorbers 8 symmetrically fixedly connected to the bottom of the placement plate 2. The bottom of the spring shock absorber 8 is fixedly connected to a rectangular plate 9, and the bottom of the rectangular plate 9 is in contact with the bottom wall of the box body 1. When the ground source heat pump unit located on the top of the placement plate 2 is working, it will generate vibration, causing the box body 1 to vibrate slightly and make a sound. The placement plate 2 is provided to prevent the ground source heat pump unit from directly contacting the bottom wall of the box body 1, and to prevent the box body 1 from vibrating along with the ground source heat pump unit. The vibration generated by the ground source heat pump unit will first cause the placement plate 2 to vibrate, and then be transmitted to the multiple spring shock absorbers 8 at the bottom of the placement plate 2. The spring shock absorbers 8 consume the vibration force generated by the ground source heat pump unit, thereby reducing the impact on the box body 1.

[0035] The present application can be used in the field of ground source heat pump units with noise reduction function, and can also be applied to other fields of the present application.

[0036] Example 2

[0037] refer to Figure 1-Figure 4, improved on the basis of Example 1: A ground source heat pump unit with noise reduction function, which is used in the field of noise reduction technology of ground source heat pump units, and also includes a noise reduction component arranged on the inner wall of the heat dissipation window 12 to reduce the sound transmitted from the heat dissipation window 12 when the ground source heat pump unit is working, and the noise reduction component includes two groups of arc plates 13 installed on the inner wall of the heat dissipation window 12, and the number of each group of arc plates 13 is at least two. When the sound waves generated by the ground source heat pump unit working arrive at the heat dissipation window 12, they will meet the arc surface of the arc plate 13, and the waveform will change and spread outward along the arc surfaces on both sides of the arc plate 13. In this process, the energy of the sound waves will be lost, so that the sound transmitted from the heat dissipation window 12 will be weakened.

[0038] In one aspect of this embodiment, referring to Figure 3 The two groups of arc-shaped plates 13 are staggered. The arc-shaped plates 13 are staggered, which can effectively gradually weaken the energy of the sound waves and make the transmitted sound gradually weaker.

[0039] In one aspect of this embodiment, referring to Figure 3 The arc plate 13 is fixed with sound insulation cotton on one side close to the box body 1. When the sound waves generated by the local heat pump unit collide with the arc plate 13, the sound insulation cotton absorbs the energy of the sound waves, greatly attenuates the sound wave energy, and improves the noise reduction effect.

[0040] In one aspect of this embodiment, referring to Figure 1 The box body 1 is made of a soundproof board, which can effectively prevent sound from passing through the box body 1.

[0041] Example 3

[0042] refer to Figure 2 , based on the improvement of Example 1: a roller 10 is fixedly mounted on the bottom of each rectangular plate 9, and a rolling groove 11 for rolling with the roller 10 is provided on the bottom wall of the box body 1. When the ground source heat pump unit needs to be lifted for maintenance or installed and disassembled, the limit between the first shell 101 and the second shell 102 is first released, and then the bolts on the outer wall of the L-shaped rod 7 are removed, and the first shell 101 and the second shell 102 are pulled successively to expose the ground source heat pump unit to the outside, and maintenance and other operations can be performed on it. The roller 10 and the rolling groove 11 are provided to facilitate pulling the first shell 101 and the second shell 102.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
