Description

Technical Field

[0001] This utility model relates to the field of air conditioning system technology, and in particular to an ethylene glycol solution circulation device integrated with an air conditioning pressure tank. Background Technology

[0002] Air conditioning pressure regulating tanks are key devices in air conditioning systems used to maintain stable pressure. By adjusting the volume of internal gas and liquid, they compensate for pressure fluctuations caused by temperature changes or leaks, ensuring the safe and efficient operation of the system.

[0003] In central air conditioning water systems, pressure tanks typically use ethylene glycol solution circulation to achieve heat transfer in low-temperature environments and prevent the solution from freezing. The integrated ethylene glycol solution circulation device in the pressure tank can use a circulation pump to circulate the ethylene glycol solution between the refrigeration unit, terminal equipment, and pipelines, thereby regulating system pressure fluctuations, maintaining stable operation, and improving energy efficiency.

[0004] However, the existing ethylene glycol solution circulation device integrated with the air conditioning pressure tank has the following shortcomings:

[0005] In the existing technology, the ethylene glycol solution circulation device integrated into the air conditioning pressure tank sometimes needs to be installed outdoors due to the limited space inside the building, to facilitate heat dissipation and ventilation of the equipment, or to reduce indoor noise interference. However, the existing device lacks protective waterproof measures, and external rainwater can penetrate and corrode the circulation pump and electrical components, leading to short circuits, reduced motor insulation performance, and even equipment failure, leakage and other safety hazards.

[0006] Therefore, we propose an ethylene glycol solution circulation device integrated with an air conditioning pressure tank to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide an ethylene glycol solution circulation device integrated with an air conditioning pressure tank. By precisely engaging three embedded blocks with the mounting bracket's embedded groove, the protective box is initially positioned. Subsequently, a threaded transmission assembly drives two embedded plates to move in opposite directions, embedding them into corresponding limiting grooves to form a multi-directional constrained tenon-and-mortise connection structure, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an ethylene glycol solution circulation device integrated with an air conditioning pressure tank, comprising a protective mechanism, wherein a shock-absorbing mechanism is provided on the outer wall of the protective mechanism;

[0009] The protective mechanism includes a mounting frame with three insertion slots on its top. Insertion blocks are movably inserted between the inner walls of the three insertion slots. A protective box is fixedly connected to the top of each insertion block. Two limiting slots are provided on the inner wall of each insertion block. A circulation device body is installed inside the protective box. Two bearings are fixedly inserted into the inner wall of the mounting frame. A bidirectional lead screw is fixedly inserted between the two bearings. Two threaded blocks are threadedly connected to the outer wall of the bidirectional lead screw. Insertion plates are fixedly connected to the top of each of the two threaded blocks. A guide rod is fixedly connected to the inner wall of the mounting frame, and the outer wall of the guide rod is movably inserted into the two threaded blocks. A throttle is fixedly connected to one side of the outer wall of each threaded block.

[0010] Preferably, the shock absorption mechanism includes a fixed frame, and a pressure stabilizing tank is fixedly connected to the top of the fixed frame.

[0011] Preferably, a set of upper support cylinders is fixedly connected to the bottom of the fixing frame, and dampers are fixedly connected to the inner surface of each set of upper support cylinders.

[0012] Preferably, a damping spring is movably sleeved on the outer wall of each group of dampers, and a lower support cylinder is fixedly connected to the bottom of each group of dampers.

[0013] Preferably, a rubber pad is fixedly connected to the bottom of each of the lower support cylinders.

[0014] Preferably, a fixing plate is fixedly connected to the bottom of each set of rubber pads.

[0015] Preferably, the inner wall of the mounting bracket is fixedly connected to the outer wall of the fixing bracket, the bottom of the circulation device body is fixedly connected to the top of the fixing bracket, and the outer walls of the two embedding plates are movably inserted into the interior of the fixing bracket.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the protective box is initially positioned by the precise engagement of three embedded blocks with the mounting bracket's embedded groove under the interaction of the various components of the protective mechanism. Subsequently, the two embedded plates are driven to move in opposite directions by the threaded transmission component, so that they are embedded in the corresponding limiting grooves, forming a mortise and tenon connection structure with multi-directional constraints. In this way, the protective box and the ethylene glycol solution circulation device can form a high-strength and stable assembly, providing the device with full-enclosed protection, effectively resisting the corrosion and penetration of external rainwater on core components such as the circulation pump, heat exchanger, and control cabinet, ensuring that the device can continue to operate stably in harsh outdoor environments such as high humidity and heavy rainfall, and reducing the risk of failures such as electrical short circuits and corrosion of mechanical parts.

[0018] 2. In this utility model, through the interaction of various components of the shock absorption mechanism, a three-stage shock absorption system composed of a damper, a shock absorption spring, and a rubber pad is used to achieve multiple shock absorption treatments for the ethylene glycol solution circulation device, so that the vibration amplitude of the equipment is strictly controlled within the industry standard limit, thereby ensuring the stability and reliability of the device operation, effectively reducing the risk of mechanical fatigue, component loosening and pipeline leakage, and extending the entire life cycle of the equipment.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4As shown, this utility model provides a technical solution: an ethylene glycol solution circulation device integrated with an air conditioning pressure tank, including a protective mechanism 1, and a shock-absorbing mechanism 2 is provided on the outer wall of the protective mechanism 1;

[0027] The protective mechanism 1 includes a mounting frame 101. The top of the mounting frame 101 has three embedding slots 102. An embedding block 103 is movably inserted between the inner walls of the three embedding slots 102. A protective box 104 is fixedly connected to the top of the embedding block 103. Two limiting slots 105 are opened on the inner wall of the embedding block 103. A circulation device body 106 is installed inside the protective box 104. Two bearings 107 are fixedly inserted into the inner wall of the mounting frame 101. A bidirectional lead screw 108 is fixedly inserted between the interior of the two bearings 107. Two threaded blocks 109 are threadedly connected to the outer wall of the bidirectional lead screw 108. An embedding plate 110 is fixedly connected to the top of each of the two threaded blocks 109. A guide rod 111 is fixedly connected to the inner wall of the mounting frame 101. The outer wall of the guide rod 111 is movably inserted into the interior of the two threaded blocks 109. A throttle 112 is fixedly connected to one side of the outer wall of the threaded block 109.

[0028] The effect achieved by the entire embodiment 1 is as follows: When the circulation device body 106 needs to be installed outdoors, the three protrusions at the bottom of the embedding block 103 are first inserted into the embedding groove 102. By rotating the handle 112, the bidirectional screw 108 is driven to rotate. Under the guidance and support of the guide rod 111, the bidirectional screw 108 drives the two threaded blocks 109 to move in opposite directions, thereby causing the embedding plate 110 to be inserted into the limiting groove 105 at the same time, so as to achieve a mortise and tenon connection between the embedding block 103 and the mounting frame 101. At this time, the protective box 104 forms a closed protective structure for the circulation device body 106, preventing external rainwater from spraying, penetrating and corroding the core components such as the circulation pump, heat exchanger and electrical control cabinet, ensuring that the device operates stably in outdoor high humidity, rainy and strong ultraviolet environment, extending the service life of the equipment and reducing the maintenance frequency.

[0029] Example 2, as Figure 2-4 As shown, the shock absorption mechanism 2 includes a fixed frame 201. A pressure stabilizing tank 202 is fixedly connected to the top of the fixed frame 201. A set of upper support cylinders 203 is fixedly connected to the bottom of the fixed frame 201. A damper 204 is fixedly connected to the inner wall of each set of upper support cylinders 203. A shock-absorbing spring 205 is movably sleeved on the outer wall of each set of dampers 204. A lower support cylinder 206 is fixedly connected to the bottom of each set of lower support cylinders 206. A rubber pad 207 is fixedly connected to the bottom of each set of lower support cylinders 206. A fixed plate 208 is fixedly connected to the bottom of each set of rubber pads 207. The inner wall of the mounting frame 101 is fixedly connected to the outer wall of the fixed frame 201. The bottom of the circulation device body 106 is fixedly connected to the top of the fixed frame 201. The outer walls of the two embedded plates 110 are movably inserted into the interior of the fixed frame 201.

[0030] The overall effect of Embodiment 2 is as follows: During operation, the vibrations generated by the circulating pump and the pressure tank 202 are transmitted sequentially through the fixed frame 201. At this time, a set of dampers 204 quickly absorbs high-frequency vibration energy and converts it into heat energy through the viscous fluid damping effect. Subsequently, the shock-absorbing spring 205 uses elastic deformation to buffer low-frequency vibration and achieves secondary vibration reduction through compression and rebound. At the same time, the rubber pad 207 further attenuates residual vibration and isolates solid-borne sound by virtue of its high elasticity and internal friction characteristics. The three work together to effectively dissipate vibration energy, keep the vibration amplitude of the equipment within the safe threshold, ensure the long-term stable operation of the device, and reduce the risk of mechanical fatigue and component loosening caused by vibration.

[0031] The working principle of the entire device is as follows: When the circulation device body 106 needs to be installed in an outdoor environment, the operator first precisely aligns the three positioning protrusions at the bottom of the embedding block 103 into the corresponding embedding slots 102 of the mounting frame 101 to form an initial positioning constraint. Then, by rotating the handle 112, the bidirectional lead screw 108 is driven to rotate. Based on the thread transmission mechanism and the guide support of the guide rod 111, the two threaded blocks 109 move synchronously in opposite directions along the axial direction, driving the embedding plate 110 to insert into the limiting slot 105 of the fixing frame 201, realizing the multi-directional constraint tenon and tenon connection between the embedding block 103 and the mounting frame 101. At this time, the protective box 104 provides support for the circulation device. The main body 106 forms a fully enclosed protection, effectively preventing external rainwater from spraying, penetrating, and electrochemically corroding core components such as the circulating pump, heat exchanger, and electrical control module. During operation, when the vibration generated by the circulating pump and pressure tank 202 is transmitted to the support structure through the fixed frame 201, a set of dampers 204 first rapidly attenuates the high-frequency vibration energy through the viscous damping effect, while a set of shock-absorbing springs 205 absorbs the low-frequency vibration impact through elastic deformation. Combined with the high elastic modulus and internal friction characteristics of a set of rubber pads 207, a three-stage vibration reduction system is formed to control the vibration amplitude within the standard limits, reducing the risk of pipe fatigue cracking, loose electrical connections, etc. caused by vibration.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
